Specifically, the ribs 301 are provided on the extended lines (on the negative side of the z-axis) of the gates 60, and the x-axis direction position and the y-axis direction position of each gate 60 are the first. The rib 301 of the mold member 30 substantially overlaps the x-axis direction position and the y-axis direction position.
The second die 6 has an x-axis positive direction side portion 61 and an x-axis negative direction side portion 62. After the second mold member 31 is formed, the second die 6 is indicated by an arrow in FIG. In this way, it is divided into both parts 61 and 62 with the dividing plane α as a boundary. The dividing surface α is provided on the x-axis negative direction side with respect to the contact surface 31c of the second mold member 31. In other words, the second mold member 31 is formed so that the dividing surface α of the second mold 6 is disposed on the x-axis negative direction side of the contact surface 31c. Specifically, the dividing surface α is provided at a substantially intermediate position in the x-axis direction of the connection flange portion 313. After the x-axis negative direction side portion 62 is separated from the x-axis positive direction side portion 61, the x-axis negative direction side portion 62 is divided into a y-axis positive direction side portion 62a and a y-axis negative direction side portion 62b with the dividing plane β shown in FIG. Is done.
A 3rd process is a process of filling the adhesive agent 32 in the shape | molded 2nd mold member 31 (the recessed part 316). The adhesive 32 has fluidity when filled in at least the second mold member 31 (recess 316), and the first mold member is adhered to the outer periphery of each of the insulators of the covered wires 10a to 10e. 30 is filled to the x-axis negative direction side rather than the end part (end surface 300) of the x-axis negative direction side.
[Operation of Example 1]
Next, the operation of the connector 1 will be described. 2. Description of the Related Art Conventionally, a connector (terminal structure) that is a connection portion for electrically connecting a plurality of electronic devices is known. A cable for connecting a plurality of devices is connected to the connector. Usually, such a cable is constituted by a covered wire in which a waterproof insulator is covered with a conductive wire. In a connector, in order to make an electrical connection, a conductive wire inside the covered wire (cable) is used. There is an exposed part (connection terminal) where the line is exposed. Since moisture from the outside enters the exposed portion, it causes corrosion and the like. Conventionally, various waterproof structures have been adopted in the connector so that moisture does not enter the exposed portion. On the other hand, from the viewpoint of simplifying the connector, it is desirable to suppress an increase in size of the connector by providing a waterproof structure. That is, it is desirable to further simplify the structure of the connector while maintaining the waterproofness (sealability) of the conductive wire. For example, a resin connector that is integrally attached to an aluminum housing of an electro-mechanical integrated electric power steering device is known, and this connector opens to the outside of the housing, and a cable ( Specifically, signal lines and power supply lines for exchanging electrical signals with the vehicle are connected. However, since this connector has a conventional structure in which two socket parts (female part and male part) provided with a waterproof structure are fitted to each other, it is difficult to reduce the size, and other vehicle parts There is also a limit in improving the layout of the electric power steering device in the vehicle by avoiding interference with the vehicle.
On the other hand, the connector (terminal structure) 1 according to the first embodiment is a waterproof member that accommodates and holds the covered wires 10a to 10e, and the exposed portion B (10B) of the covered wires 10a to 10e. The 1st mold member 30 which accommodates a boundary part with the coating | coated part A inside was provided. In other words, the exposed portion B of the first mold member 30 protrudes from one end side thereof (of the conductive members 11a to 11e connected to the exposed portions 10B of the covered wires 10a to 10e, respectively), and the covered portion A extends from the other end side. It is formed to protrude. Therefore, in the connector 1 (first mold member 30), one end side (x-axis positive direction side) from which the exposed portion B protrudes is disposed inside the electronic device (housing 2), and the other end side from which the covering portion B protrudes. If the (x-axis negative direction side) is disposed outside the electronic device (housing 2), it is possible to suppress moisture from entering the exposed portion B from the outside. The structure of such a connector 1 is “a conventional connector in which two sockets (female part and male part) are connected to each other and a waterproof seal structure is provided between these sockets (both or one of the sockets). This corresponds to a structure in which one socket in the “structure” is omitted, and the structure is simpler because the one socket does not need to be provided. Therefore, the structure of the connector can be further simplified while obtaining the sealing property (waterproofness) of the conductive wire, and the connector 1 can be downsized to reduce the size of the device PS (gear unit GU) provided with the connector 1. The layout in the vehicle can also be improved. In the first embodiment, the control unit ECU and the gear unit GU are separated and connected by the signal line L2 or the like. However, they may be integrated. In this case, the present invention may be applied to a connector that connects the control unit ECU and the torque sensor TS directly and electrically and also connects the control unit ECU and an external device. In addition, the 1st mold member 30 is good also as not accommodating the coating | coated part A (boundary part with the exposed part B) inside. In this case, if the boundary portion between the exposed portion B and the covering portion A is accommodated in the adhesive 32, the exposed portion B can be waterproofed to obtain the above effect.
Here, the first mold member 30 is a resin member. Thus, the above-mentioned effect can be improved by using as the first mold member 30 a resin material that is excellent in waterproofness and retention of the covered wires 10a to 10e. Note that the material is not limited to resin as long as the material can sufficiently and sufficiently secure the waterproofness and retention of the covered wire 10. Further, since the first mold member 30 is molded as a resin member, the processing can be facilitated. Moreover, the 1st mold member 30 fixes the relative position of several covered wire | line 10a-10e by becoming a solid state at least after shaping | molding. For this reason, the relative positioning of the covered wires 10a to 10e and the conductive members 11a to 11e can be realized without providing any special position restricting means after molding. Therefore, the structure of the connector 1 can be further simplified. In addition, as long as the relative position can be regulated to such an extent that the exposed portions of the covered wires 10a to 10e (conductive members 11a to 11e) do not come into contact with each other, the first mold member 30 may not be in a completely solid state after molding. In this case, for example, a position restricting means for suppressing contact may be provided.
In the first mold member 30 of the first embodiment, the pins 5a to 5d are inserted between the plurality of covered wires 10a to 10e (exposed portions 10B), and the relative positions of the covered wires 10a to 10e are restricted. It has holes 30a to 30d formed by molding. That is, the pins 5a to 5d are used as means for restricting the positions of the covered wires 10a to 10e only while the first mold member 30 is being molded. Therefore, when the first mold member 30 is molded, the relative positional accuracy between the covered wires 10a to 10e can be improved, and the contact between the exposed portions 10B of the covered wires 10a to 10e can be more reliably suppressed. It is also conceivable that the mold is formed such that the exposed portions 10B of the covered wires 10a to 10e and the conductive members 11a to 11e are exposed in the holes 30a to 30d formed by the pins 5a to 5d. However, in the present Example 1, since the 2nd mold member 31 is shape | molded so that the outer periphery of the 1st mold member 30 may be enclosed and the opening of holes 30a-30d is closed, a waterproof fall can be suppressed. In the first embodiment, the pins 5a to 5d are inserted between the exposed portions 10B of the covered wires 10a to 10e, but the pins are covered between the portions (covered portions) covered with the insulator of the covered wires 10a to 10e. 5a to 5d may be inserted, and in this case, contact between the exposed portions 10B can be suppressed to some extent while suppressing a situation where the holes 30a to 30d and the exposed portion 10B communicate with each other.
In the first step, the first mold member 30 is formed in a state where the conductive members 11a to 11e are integrally connected to each other by the connection portion 11B. Therefore, since the relative positional accuracy between the conductive members 11a to 11e can be easily obtained, when the connector 1 is installed, the terminals (conductive members 11a to 11e) of the connector 1 projecting into the housing 2 and the terminals (conductive members 11a to 11e). The relative positional accuracy with the member (substrate 200) of the electronic device (torque sensor TS) as the connection counterpart in 11e) is improved, whereby the electrical connectivity of the connector 1 can be improved. The connecting portion 11B is cut so as to insulate the conductive members 11a to 11e in a step after the first step. That is, when the first step is completed, the first mold member 30 is in a fixed state, and the positions of the conductive members 11a to 11e are fixed by the first mold member 30. By cutting the connection portion 11B in this state, the relative positional accuracy between the conductive members 11a to 11e can be maintained high.
As the resin material for forming the first mold member 30, a material that does not adhere to the insulator is adopted. Therefore, when the first mold member 30 is molded, since the adhesion between the first mold member 30 and the first mold 4 is suppressed, the product (the first mold member 30) is separated from the first mold 4. Good type. Therefore, workability can be improved. However, when the first mold member 30 is formed of a material that does not adhere to the insulator as described above, adhesion between the first mold member 30 and the insulator of the covered wires 10a to 10e is also suppressed. Therefore, when a force that bends or pulls the covered wires 10a to 10e from the signal line L21 side or when exposed to severe temperature conditions, the first mold member 30 and the covered wires 10a to 10e A certain amount of gap may be formed between the insulators. Therefore, it is necessary to seal the gap to ensure waterproofness. On the other hand, in the present Example 1, this gap was covered with the adhesive 32 as a sealing member. That is, in the first mold member 30, the end portion (end surface 300 where the gap is opened) on the side where the covering portion A of the covered wires 10 a to 10 e protrudes (the negative direction side on the x axis) and the covered wires 10 a to 10 e (covering portion A). ) Is provided with an adhesive 32 for sealing between the outer periphery of the insulator. The adhesive 32 is attached to the outer periphery of each of the insulators of the covered wires 10a to 10e from the end (surface 300) of the first mold member 30 on the negative side of the x axis in the x axis of the covered wires 10a to 10e. Fills up to the negative side (insulator). Therefore, moisture can be prevented from entering the exposed portion B from the outer periphery (the gap) of the covered wires 10a to 10e (insulator), and the waterproof property can be improved. The material of the first mold member 30 only needs to be a material that does not adhere to the first mold 4 to some extent (so as to ensure releasability), and does not need to be a material that does not strictly adhere to the insulator. In other words, the adhesive 32 and the structure (recessed portion) for holding the adhesive 32 may be provided as long as the adhesive between the first mold member 30 and the insulators of the covered wires 10a to 10e can be secured. It is also possible to omit 316). The adhesive 32 does not need to be filled in the entire volume of the recess 316, is in close contact with the x-axis negative direction side (surface 315) of the first mold member 30, and is an insulator of the covered wires 10a to 10e. By adhering to the outer periphery, any material may be used as long as moisture is prevented from entering the first mold member 30 (exposed portion B) from the outer periphery of each of the covered wires 10a to 10e. Further, the adhesive 32 does not need to be provided in the entire range of the surface 300, and only a portion necessary for sealing the gap, for example, an outer peripheral portion of each of the covered wires 10a to 10e (opening portion of the gap in the surface 300). It is good also as providing only in this case, The said effect can be acquired also in this case.
As a material of the adhesive 32, a silicone resin having high adhesiveness with the insulators of the covered wires 10a to 10e is used. Specifically, a soft silicone resin is used, and the seal member formed by the adhesive 32 is elastic. For this reason, for example, there is followability to the force to bend, and even if the covering portion A (insulator) of the covered wires 10a to 10e is bent, it bends following this. Therefore, even when a force acts on the covered wires 10a to 10e to cause a fall or the like, a gap is hardly generated between the adhesive 32 and the covered wires 10a to 10e (insulator), and the waterproofness can be further improved. Note that the material of the adhesive 32 is not limited to a soft resin, and may be a hard resin. For example, a hard epoxy resin may be used. When a hard resin is used, not only can the adhesiveness with the coated wires 10a to 10e be ensured in the same manner as the soft resin, but also the adhesive 32 is excellent in strength, and therefore the adhesive 32 due to the falling of the coated wires 10a to 10e. There is an advantage that durability sufficient can be improved by securing a sufficient strength against the load. Here, when the linear expansion coefficient of each material is compared, for example, the soft silicone resin is 63 × 10 −6 and the hard epoxy resin is 177 × 10 −6, while the adhesive 32 is filled and bonded. The linear expansion coefficient of the PBT resin as the material of the second mold members 30 and 31 is 75 × 10 −6, and the flame-retardant polyethylene as the insulating material for covering the coated wires 10a to 10e is 180 × 10 −6. is there. That is, the soft silicone resin has a linear expansion coefficient closer to that of the PBT resin than the hard epoxy resin. Therefore, if the soft silicone resin is used as the material of the adhesive 32 as in the first embodiment, the adhesive 32 can be prevented from being peeled off from the first and second mold members 30 and 31 due to a temperature change. It is possible to suppress the generation of a gap between the adhesive 32 and the first and second mold members 30 and 31 (concave portion 316), and to improve the waterproofness. On the other hand, when the strength (tensile strength) of each material is compared, for example, soft silicone resin is 0.2 MPa and hard epoxy resin is 82.7 MPa, while PBT which is a material of the first and second mold members 30 and 31 is used. The tensile strength of the resin is 118 MPa, and the flame-retardant polyethylene that is the insulator material of the covered wires 10a to 10e is 10 MPa. That is, the soft silicone resin has a lower tensile strength than the flame retardant polyethylene, whereas the hard epoxy resin has a higher tensile strength than the flame retardant polyethylene. Therefore, if a hard epoxy resin is used as the material of the adhesive 32, the adhesive 32 can be prevented from breaking against the load applied to the adhesive 32 due to the falling of the covered wires 10a to 10e. It is possible to suppress the occurrence of gaps (cracks) in the interior of 32 and improve durability and waterproofness. Considering the material characteristics as described above, for example, a gap between the adhesive 32 and the first and second mold members 30 and 31 (recess 316) due to a temperature change, or the inside of the adhesive 32 due to a load. From the viewpoint of suppressing cracking and improving waterproofness and durability, the material of the adhesive 32 has a coefficient of linear expansion close to that of the first and second mold members 30 and 31 (for example, 75 × A material having a tensile strength equal to or higher than the material of the covered wires 10a to 10e (insulator) (for example, 10 MPa or more) is preferable.
The first mold member 30 is provided with a second mold member 31 as a housing member for the adhesive 32. That is, the second mold member 31 includes an annular wall portion 310, and the wall portion 310 projects to the x-axis negative direction side with respect to the x-axis negative direction end (surface 300) of the first mold member 30 and is covered. It is formed so as to surround the outer periphery of the covering portion A of the wires 10a to 10e. As described above, the wall 310 protrudes in the negative x-axis direction from the surface 300 and is disposed on the outer peripheral side of the covering portion A. Therefore, the wall 310 is located on the inner peripheral side of the wall 310 (at least in the negative x-axis direction from the surface 300). When the adhesive 32 is filled, the opening of the gap (between the first mold member 30 and the insulator of the covered wire 10) on the end surface 300 of the first mold member 30 is closed and the covered wires 10a to 10e are covered. It is possible to seal between the outer periphery of each of the insulators and the opening. Therefore, the arrangement | positioning operation | work of the adhesive agent 32 is facilitated and the said clearance gap can be efficiently sealed with the adhesive agent 32. FIG. Further, since the wall 310 is provided in an annular shape, the fluid adhesive 32 can be held on the inner peripheral side of the wall 310 when the adhesive 32 is filled. Therefore, the filling operation of the adhesive 32 can be made efficient. In other words, the process of forming the sealing member composed of the adhesive 32 can be simplified. Although there is a possibility that a gap is generated between the first and second mold members 30 and 31 (between the inner periphery of the fitting hole 314 and the outer periphery of the first mold member 30), in the first embodiment, Since the wall portion 310 is also provided so as to surround the outer periphery of the first mold member 30, the gap is sealed by filling the inner peripheral side (recess 316) of the adhesive portion 32 with the gap 310. Ingress of water through is suppressed. In the first embodiment, the wall 310 is provided in a quadrangular prism shape, and the thickness of the z-axis direction side portion is thicker than the y-axis direction side portion when viewed from the x-axis direction. In this way, the wall 310 may be provided in an oval shape having a substantially uniform thickness over the entire circumference when viewed from the x-axis direction. In this case, the outer periphery of the connection main body 312 is similar to the wall 310. It can be a shape.
The second mold member 31 includes a connection portion 311, and the connection portion 311 is provided on the positive side in the x-axis direction of the wall portion 310 and connects the wall portion 310 and the first mold member 30 in a liquid-tight manner. . Therefore, when connecting the connector 1 (first mold member 30) to the electronic device (torque sensor TS), the connecting portion 311 has only to be installed in the electronic device (housing 2), and the first mold member 30 is directly connected to the housing 2. No need to install. Accordingly, without providing a special sealing member between the first mold member 30 and the housing 2 (through hole 220), only the liquid tightness between the second mold member 31 (connecting portion 311) and the housing 2 is achieved. Since both may be connected in consideration, the connection of the connector 1 can be facilitated (connectivity is improved). Specifically, the second mold member 31 is provided with a contact surface 31c on the end surface on the x-axis positive direction side, and when the connector 1 is connected to the torque sensor TS, the contact surface 31c is the housing 2. It abuts on (connector installation part 22). Because of this contact (surface contact), it is possible to ensure the bondability (sealability) between the connector 1 and the housing 2 (connector installation portion 22), so that water enters the housing 2 through the through hole 220. Thus, contact with the exposed portion B of the covered wire 10 (conductive member 11) can be suppressed. Here, the second mold member 31 is formed such that the dividing surface α of the second mold 6 is disposed on the x-axis negative direction side of the contact surface 31c. Therefore, the split surface α does not interfere with the contact surface 31c, and the contact surface 31c can be more reliably formed into six shapes (seal surfaces) of the second mold, so that the contact surface 31c is joined to the housing 2. (Sealability) can be improved.
The second mold member 31 is provided with pins 31a and 31b as engaging portions on the end surface 31c on the x-axis positive direction side. When the connector 1 is connected to an electronic device (torque sensor TS), the pin 31a and 31b engage with the electronic device (engagement hole of the housing 2). Therefore, the relative positional accuracy between the second mold member 31 (and the first mold member 30 accommodated therein) and the electronic apparatus (housing 2) can be improved. Therefore, the terminal (conductive members 11a to 11e) of the connector 1 protruding into the housing 2 and the member (substrate 200) of the electronic device (torque sensor TS) that is the counterpart of the terminals (conductive members 11a to 11e). The relative positional accuracy is improved, and thereby the electrical connectivity of the connector 1 can be improved. In other words, it is possible to improve workability when the board 200 is installed in the housing 2 and the terminals 11a to 11e are connected. Note that the number, shape, and position of the pins 31a and 31b are not particularly limited. In the first embodiment, the pins 31a and 31b are provided as the engaging portions. However, any pin may be used as long as positioning can be realized by fitting, and for example, a claw-shaped (snap fit) structure may be used. Further, a protruding portion may be provided on the housing 2 side, and a concave portion to be fitted to this may be provided on the connector 1 side. Moreover, it is good also as positioning by providing the mark of a connector position on the housing 2 side irrespective of fitting.
The contact surface 31c of the second mold member 31 is provided with an annular seal groove 318 into which an O-ring S as a seal member is inserted. When the connector 1 is connected to the torque sensor TS, The installed O-ring S seals the gap between the housing 2 (connector installation portion 22) and the connector 1 (contact surface 31c). That is, the seal groove 318 and the seal member S may be omitted. In this case, it is possible to ensure the sealing performance by the contact (surface contact) between the contact surface 31c and the connector installation portion 22, By providing the seal member (O-ring S) as in the first embodiment, it is possible to further improve the bondability (sealability) between the connector 1 and the electronic device (housing 2) on the contact surface 31c. For example, even if the contact surface 31c is not in contact (surface contact) with the housing 2 over the entire range, if the O-ring S is in close contact with the housing 2, a desired sealing property can be obtained. The seal groove may be provided on the electronic device (housing 2) side, or the seal groove 318 may be omitted. In the first embodiment, the connector 1 (second mold member 31) is fastened and fixed to the electronic device (the connector installation portion 22 of the housing 2) by the bolt b. Therefore, the O-ring S is crushed in the x-axis direction by the axial force of the bolt b, and thereby the adhesion between the O-ring S and the housing 2 is improved, so that the sealing performance can be further improved. From the viewpoint of downsizing the connector 1 or the like, it is preferable to reduce the thickness of the second mold member 31 (connecting portion 311) (reducing the x-axis direction dimension). On the other hand, in the second mold member 31 (connecting portion 311), the portion provided with the seal groove 318 has a reduced x-axis direction dimension (wall thickness), and the pressing force of the O-ring S may act. Strength may be reduced. For example, the second mold member 31 (connecting portion 311) may be bent at the site where the seal groove 318 is provided. On the other hand, in the first embodiment, the seal groove 318 is disposed so as to overlap the wall portion 310 when viewed from the x-axis direction. Therefore, the reduction in the x-axis direction dimension of the portion provided with the seal groove 318 is compensated by the x-axis direction dimension of the wall portion 310 (the strength reduction of the portion provided with the seal groove 318 is compensated by the wall portion 310). Creep (deformation) of the two mold member 31 (connection portion 311) can be suppressed. In the first embodiment, in the direction perpendicular to the x-axis direction (longitudinal direction of the covered wire 10), that is, in the y-axis direction and the z-axis direction in which the wall 310 extends, the seal groove 318 and the wall 310 are viewed from the x-axis direction. Are arranged to overlap. Note that it is only necessary to partially overlap when viewed from the x-axis direction, and one of the seal groove 318 and the wall portion 310 may not completely overlap (include) the other. That is, it is sufficient that the second mold member 31 overlaps (preferably half or more) to such an extent that a shortage of strength (thickness) can be suppressed.
The second mold member 31 is formed by insert molding in which mold molding is performed with the first mold member 30 inserted into the second mold 6. By dividing the molding into two times in this way, a relatively complicated shape such as a wall portion 310 for holding the adhesive 32 and a connection portion 311 for facilitating connection to an electronic device can be formed in the connector 1 ( It becomes easy to form the second mold member 31). In other words, when the second mold member 31 is formed (manufactured) in a process different from that of the first mold member 30, each of the first and second mold members 30 and 31 can be easily molded. Moreover, since it becomes possible to shape | mold the 1st, 2nd mold members 30 and 31 with the material which has another characteristic, respectively, a moldability (workability) can be improved more. Note that the first and second mold members 30 and 31 may be integrally formed in the same process without being a separate process. Further, the shape of the connection portion 311 (wall portion 310) or the like may be formed by another process (molding).
The wall portion 310 is provided at a predetermined distance (y-axis direction and z-axis direction) from the outer peripheral surface of the first mold member 30 in the circumferential direction of the first mold member 30. Therefore, the second mold 6 can be structured so as not to interfere (contact) with the insulator of the covered wire 10. Thereby, the moldability of the second mold member 31 can be improved. That is, unlike the first mold member 30, the second mold member 31 has a complicated structure having an annular wall portion 310 and the like, and the removal direction of the second mold 6 is also greatly limited (the removal direction is mainly x Limited in the axial direction). Further, from the x-axis negative direction end surface 300 of the first mold member 30, the covered wires 10 a to 10 e (covered portion A) extend in the x-axis negative direction side. Therefore, when removing the 2nd type | mold 6, the 2nd type | mold 6 which forms the inner peripheral side of the wall part 310 surrounding the covering wire 10a-10e (covering part A) becomes covering wire 10a-10e (covering part A). When contacted, the insulators of the covered wires 10a to 10e may be damaged and peeled off (the internal conductive wires are exposed). Therefore, in the first embodiment, the structure is such that the second mold 6 can be easily pulled out and the second mold 6 is unlikely to interfere (contact) with the insulator of the covered wire 10 at the time of mold cutting. Specifically, a through hole 620 is formed through the inner periphery of the portion of the second mold 6 that forms the inner periphery of the wall 310 in the x-axis direction. The through hole 620 is provided in a shape surrounding the outer periphery of the first mold member 30. When the second mold member 31 is molded, the x-axis negative direction side of the first mold member 30 is fitted to the x-axis positive direction side of the through-hole 620, and the covered wires 10a to 10e extending from the end surface 300 (cover portion A) Is installed through the through hole 620. At the time of die cutting, both the x-axis positive and negative side portions 61 and 62 of the second mold 6 are separated and removed in the x-axis direction, and the x-axis negative direction side portion 62 is removed in the axial direction of the first mold member 30 (x-axis negative side). To the direction side). At this time, since the covered wires 10a to 10e only move relatively in the x-axis direction in the through hole 620, the second mold 6 (the inner peripheral surface of the through hole 620) and the insulators of the covered wires 10a to 10e Is prevented from sliding. Therefore, the second mold 6 can be removed without taking excessive care so as not to impair the insulating properties of the covering portion A, so that the moldability of the second mold member 31 can be improved. In addition, a predetermined distance from the outer peripheral surface of the first mold member 30 is not set, for example, adjacent to the first mold member 30 (along the outer periphery of the first mold member 30), compared with the case where the wall portion 310 is provided. Since it is easy to ensure the thickness of the second mold 6 disposed on the inner peripheral side of the wall portion 310 while avoiding interference with the covering portion A, the moldability of the second mold member 31 (wall portion 310) is improved. be able to. In the first embodiment, the annular wall 310 is formed so as to be separated from the outer peripheral surface of the first mold member 30 over the entire circumference in the circumferential direction. In other words, the wall portion 310 is provided at a predetermined distance (y-axis direction and z-axis direction) from the entire outer periphery of the first mold member 30. Therefore, the above effect can be obtained more reliably.
The outer surface of the first mold member 30 is combined with the inner surface of the second mold 6 to form one space, and this space is filled with the material of the second mold member 31. For this reason, it is important to ensure a sealing property between the outer surface of the first mold member 30 and the inner surface of the second mold 6 (so that the filling material does not leak to the outside of the second mold 6). For example, when the x-axis negative direction end (surface 300) of the first mold member 30 is provided at the same x-axis direction position as the x-axis negative direction end surface 315 of the connection part 311 of the second mold member 31, the connection part 311 is provided. The seal length between the inner surface of the second mold 6 to be molded and the outer surface of the first mold member 30 (of the x-axis negative direction side) (which forms a space filled with the material together with the second mold 6) (Area where both are in contact) becomes substantially zero, and there is a risk that the material leaks from between the two. On the other hand, in the first embodiment, the x-axis negative direction side (end surface 300) of the first mold member 30 is the second mold member 31 (the x-axis negative direction end surface 315 of the connecting portion 311 surrounded by the wall portion 310). The second mold member 31 is formed so as to protrude from the X axis negative direction side. Therefore, the second mold member 31 can be molded in a state where the x-axis negative direction side of the first mold member 30 is fitted into the through hole 620 of the second mold 6, and at this time, the first mold member The sealing surface formed between 30 and the second mold 6 can be secured by the amount of protrusion of the first mold member 30 (that is, the distance in the x-axis direction of the fitting portion). Accordingly, when the second mold 6 is filled with the material and the second mold member 31 is molded, the second mold 6 has good sealing performance, and the filling material leaks when the space is filled with the material. Since it can suppress, moldability can be improved. Moreover, the x-axis negative direction end of the first mold member 30 protrudes from the x-axis negative direction end surface 315 of the connecting portion 311 surrounded by the wall portion 310 to the x-axis negative direction side, in other words, the first mold. It is also that the wall portion 310 is provided at a predetermined distance (y-axis direction and z-axis direction) from the outer surface of the member 30. Therefore, as described above, damage to the covered wires 10a to 10e due to the interference of the second mold 6 can be suppressed, and the moldability can be improved.
The first mold member 30 has a rib 301 at a portion surrounded by the second mold member 31. The rib 301 has a smaller heat capacity than other parts of the first mold member 30 and is easily melted at a high temperature. Therefore, at the time of insert molding by the second mold 6, the joining between the first mold member 30 and the second mold member 31 can be improved by first waiting in a state where the rib 301 is melted. Specifically, the rib 301 is provided adjacent to the molten material injection port (gate 60) provided in the second mold 6. Therefore, when the second resin material melted at a high temperature is injected into the second mold 6 through the gate 60, the rib 301 is first melted at a high temperature (as compared to other parts in the second mold 6). Since the material comes into contact with the ribs 301 and the ribs 301 are more easily melted, the bondability between the first mold member 30 and the second mold member 31 can be further improved.

Engagement portions (pins 31a and 31b) that engage with the first electronic device (housing 2) when connected to TS) are provided.
Therefore, the electrical connectivity of the connector 1 can be improved.
(11) The housing member (second mold member 31) is provided on the end surface of the housing member on the exposed portion B side (x-axis positive direction side), and is a first electronic device (torque sensor) that is one of a plurality of electronic devices. The contact surface 31c that comes into contact with the first electronic device (housing 2) when connected to the TS), and an annular groove provided in the contact surface 31c, the first electronic device and the contact surface 31c. And a seal groove 318 into which a seal member (O-ring S) is inserted, and the seal groove 318 is a wall portion in a perpendicular direction (in the yz plane) of the covered wires 10a to 10e (longitudinal direction). Arranged to overlap 310.
Therefore, the sealing performance of the connector 1 can be improved, and the strength reduction can be suppressed while the connector 1 is downsized.
(12) The manufacturing method of the connector 1 is a manufacturing method of a connector for electrically connecting a plurality of electronic devices (the torque sensor TS and the control unit ECU), and a covered region A in which a conductive wire is covered with an insulator. And an exposed portion B that is provided on one end side (x-axis positive direction side) and is exposed from the insulator (exposed portion B where the conductive wire is exposed) or the conductive members 11a to 11e connected to the conductive wire. Forming the first mold member 30 with the first mold 4 on the covered wires 10a to 10e, and filling the first mold 4 with the first resin material as the material of the first mold member 30; The method includes a step of releasing the first mold 4 after the first resin material is solidified, and the first resin material maintains a solid state after molding, thereby fixing the relative positions of the plurality of covered wires 10a to 10e. In addition, the first mold member 30 is a boundary between the exposed portion B of the covered wires 10a to 10e and the covered region A. The exposed portion B protrudes from one end side (x-axis positive direction side) of the first mold member 30 and the covering region A protrudes from the other end side (x-axis negative direction side). The first step and the step of forming the second mold member 31 provided on the first mold member 30 with the second mold 6, with the first mold member 30 installed in the second mold 6. A step of filling the second mold 6 with the second resin material, which is the material of the second mold member 31, and releasing the second mold 6 after the second resin material is solidified; The first mold member 30 is held by maintaining a solid state after molding, and the second mold member 31 is an end of the first mold member 30 on the side where the covering region A protrudes (the negative direction side on the x axis). (Surface 300) protrudes to the other end side (x-axis negative direction side) of the covered wires 10a to 10e and outside the covered region A An annular wall 310 formed so as to surround the circumference, and is provided on the exposed portion B side (x-axis positive direction side) of the wall 310 so that the space between the wall 310 and the first mold member 30 is liquid-tight.

An end (surface 300) on the side (x-axis negative direction side) from which the coating region A of the first mold member 30 protrudes so as to adhere to the outer periphery of each of the insulators of the coated wires 10a to 10e. 3rd process filled to the other end side (x-axis negative direction side) of the covered wire 10 rather than.
Therefore, the first mold member 30 can fix the relative positions of the plurality of covered wires 10a to 10e. In addition, the first mold member 30 can be easily molded by manufacturing the second mold member 31 in a separate process from the first mold member 30. And the penetration | invasion of the water | moisture from the covered wire | line 10a-10e outer periphery can be suppressed by filling the accommodating part (recessed part 316) with the adhesive agent 32 adhere | attached on the outer periphery of the covered wire | line 10a-10e. Further, by providing the storage portion (recess 316), when the adhesive 32 is filled, the fluid adhesive 32 can be held in the storage portion, so that the work of filling the adhesive 32 can be made more efficient.
(13) The second mold member 31 has the other end side (x-axis negative direction side) end (surface 300) of the covered wire 10a to 10e of the first mold member 30 at the connection portion 311 (surface 315) of the second mold member 31. ) To the other end side (x-axis negative direction side) of the covered wires 10a to 10e.
Therefore, since the sealing part with respect to the insert part of the 2nd type | mold 6 can be made into the 1st mold member 30 (the x-axis negative direction side) instead of the covered wire 10a-10e, the insert molding by the 2nd type | mold 6 is possible. It becomes easy. Further, the possibility of damaging the covered wires 10a to 10e by the second mold 6 can be reduced.
(14) The conductive members 11a to 11e are connected to the plurality of covered wires 10a to 10e, respectively. In the first step, the conductive members 11a to 11e connected to the covered wires 10a to 10e are the conductive members 11a to 11e, respectively. The 1st mold member 30 is formed in the state connected integrally by the connection part 11B which connects 11e.
Therefore, the relative positional accuracy between the conductive members 11a to 11e can be improved, and the electrical connectivity of the connector 1 can be improved.
(15) The connecting portion 11B is cut so as to insulate the conductive members 11a to 11e in a step after the first step.
Therefore, the relative positional accuracy between the conductive members 11a to 11e can be maintained high, and the effect (14) can be improved.
The connector 1 of the second embodiment is different from the first embodiment in the shape of the wall portion 310 (recess 316) of the second mold member 31. FIG. 15 is a front view similar to FIG. 7, in which the connector 1 of the second embodiment is viewed from the x-axis negative direction side. The illustration of the bolt through hole 319 and the like is omitted. As shown in FIG. 15, the annular wall portion 310 extends from the outer peripheral surface of the first mold member 30 at a predetermined range in the circumferential direction of the first mold member 30, specifically, on both sides in the z-axis direction of the first mold member 30. It is formed so as to be separated from each other, and is formed so as to be adjacent (approached) to the first mold member 30 on a portion excluding the predetermined range in the circumferential direction, specifically on both sides in the y-axis direction of the first mold member 30. That is, both side portions in the y-axis direction of the wall portion 310 are provided thicker on the inner peripheral side than in the first embodiment, and when viewed from the x-axis direction, the inner peripheral surface of the wall portion 310 is on both sides in the y-axis direction. The first mold member 30 is provided so as to substantially coincide with the outer peripheral surface. Since other configurations are the same as those of the first embodiment, the description thereof is omitted.
Therefore, in the concave portion 316 of the second embodiment, the adhesive 32 is not filled between the wall portion 310 and the first mold member 30 in both the positive and negative y-axis portions where the wall portion 310 and the first mold member 30 are adjacent to each other. . Therefore, the amount of the adhesive 32 used can be reduced as compared with the first embodiment. In other words, in the first embodiment, the wall portion 310 is formed so as to be separated from the entire peripheral surface of the first mold member 30 by a predetermined distance, but this separation distance may not be provided over the entire outer periphery of the first mold member 30. Good. Also in this case, if the annular wall portion 310 is formed so as to be separated from the outer peripheral surface of the first mold member 30 in a predetermined range in the circumferential direction, the insulator of the covered wires 10a to 10e and the second are formed as in the first embodiment. It is possible to improve the moldability of the second mold member 31 (wall portion 310) by suppressing interference with the mold 6 to some extent. In the second embodiment, a predetermined separation distance is secured on both the positive and negative z-axis sides of the first mold member 30 (the influence of interference with the second mold 6 is large because all the covered wires 10a to 10e face each other). Since the wall portion 310 is formed as described above, interference with the second mold 6 can be more effectively suppressed.
The annular wall portion 310 is formed so as to be separated from the outer peripheral surface of the first mold member 30 in a predetermined range in the circumferential direction, and is formed so as to be adjacent to the first mold member 30 in a portion excluding the predetermined range in the circumferential direction.
Therefore, the usage amount of the adhesive 32 can be reduced, and the manufacturing cost of the connector 1 can be reduced.
The connector 1 of the third embodiment is different from the first embodiment in the shape of the wall portion 310 (recess 316) of the second mold member 31. FIG. 16 is a partial cross-sectional view similar to FIG. 6 of the connector 1 of the third embodiment, and shows only the y-axis negative direction side portion. The illustration of the seal groove 318, the pin 31b, etc. is omitted. As shown in FIG. 16, the second mold member 31 has an inner peripheral surface of the wall portion 310 that moves from the x-axis negative direction side (opening side) toward the x-axis positive direction side (the bottom surface 315 side) (inner periphery). It is formed in an inclined shape so as to approach the first mold member 30 on the side. In other words, a tapered portion T is provided on the inner peripheral surface of the concave portion 316 that accommodates the adhesive 32 so that the dimension (inner diameter) in the y-axis direction gradually decreases toward the bottom on the x-axis positive direction side. . Since other configurations are the same as those of the first embodiment, the description thereof is omitted.
Therefore, the amount of the adhesive 32 can be reduced by making the volume of the recess 316 smaller than that of the first embodiment by the amount of the tapered portion T provided. The adhesion range between the adhesive 32 and the end surface 300 of the first mold member 30 and the covered wires 10a to 10e is maintained in the same manner as in the first embodiment. The shape of the taper portion T may be flat or curved (R shape).
The housing member (second mold member 31) is a first mold member as the inner peripheral surface of the wall 310 moves from the other end side (x-axis negative direction side) of the covered wire 10 toward one end side (x-axis positive direction side). It is formed in an inclined shape so as to approach 30.
The connector 1 of the fourth embodiment is different from the first embodiment in the shape of the adhesive 32. FIG. 17 is a partial cross-sectional view similar to FIG. 6 of the connector 1 of Example 4, and shows only the vicinity of the covered wire 10a. In addition, since it is the same structure also about the vicinity of the other covered wires 10b-10e, description is abbreviate | omitted. As shown in FIG. 17, the adhesive 32 has a fillet portion 32a at a boundary portion with the covered wire 10a. The fillet portion 32a is formed by being pulled up by the surface tension of the adhesive 32 toward the x-axis negative direction side from the x-axis negative direction side end surface 320 of the adhesive 32 filled in the concave portion 316. The wire 10a is bonded to cover the outer periphery. In addition, as a material of the adhesive agent 32, what can generate | occur | produce an appropriate surface tension when it has fluidity | liquidity at the time of filling to the recessed part 316 can be selected. The fillet portion 32a gradually decreases in its outer diameter (radius centered on the covered wire 10a in the yz plane) from the x-axis positive direction side (base end side) toward the x-axis negative direction side (tip end side). It is formed as follows. Specifically, the outer diameter R of the end portion (surface 320) on the x-axis positive direction side of the fillet portion 32a is gradually larger than the length H of the fillet portion 32a in the longitudinal direction (x-axis direction) of the covered wire 10. It is formed as follows. Since other configurations are the same as those of the first embodiment, the description thereof is omitted.
The seal length between the adhesive 32 and the covered wire 10 (the seal length in the longitudinal direction of the covered wire 10) is longer than that of the first embodiment due to the fillet portion 32a pulled up from the end surface 320 toward the negative x-axis direction. Secured. In other words, even when the x-axis negative direction side end surface 320 of the adhesive 32 is provided on the x-axis positive direction side (lower in the recess 316) than in the first embodiment, the same seal as in the first embodiment is provided by the fillet portion 32a. Since the length, that is, the sealing property (waterproofness) can be ensured, the amount of the adhesive 32 used can be reduced by the amount that the end face 320 can be lowered. Further, since the fillet portion 32a is formed in a tapered shape so that the outer diameter R gradually decreases, stress concentration at the boundary portion between the adhesive 32 and the covered wires 10a to 10e can be reduced. Therefore, generation | occurrence | production of the crack of the adhesive agent 32 with respect to the bending of the covered wire | line 10a-10e can be suppressed in the said boundary part. Therefore, the waterproofness of the connector 1 can be improved. The tapered shape may be flat or curved (R shape). Further, by making the fillet portion 32a a so-called flat shape whose outer diameter R is larger than the length H, the rigidity of the fillet portion 32a against the bending of the covered wires 10a to 10e can be further improved. Thereby, the crack of the fillet part 32a can be suppressed and the above effect can be improved.
[Effect of Example 4]
(1) The adhesive 32 has the other end side (x-axis negative direction side) of the covered wire 10 than the end surface 320 of the other end side (x-axis negative direction side) of the coated wire 10a to 10e due to the surface tension of the adhesive 32. ) And a fillet portion 32a formed so as to cover the outer periphery of the covered wires 10a to 10e.
Therefore, the waterproofness of the connector 1 can be improved.
(2) The fillet portion 32a gradually decreases as the outer diameter R of the fillet portion 32a moves from one end side (x-axis positive direction side) to the other end side direction (x-axis negative direction side) of the covered wires 10a to 10e. The outer diameter R of one end of the coated wire 10a to 10e (the base end or the surface 320 of the adhesive 32) of the fillet portion 32a is the length of the coated wire 10a to 10e in the longitudinal direction (x-axis direction). It is formed to be larger than H. Therefore, the effect (1) can be improved.
The connector 1 of the fifth embodiment is different from the first embodiment in the shapes of the second mold member 31 and the adhesive 32. 18 is a partial cross-sectional view similar to FIG. 6 of the connector 1 according to the fifth embodiment (substantially equivalent to the cross-section taken along the line III-III in FIG. 19). FIG. 19 is a front view similar to FIG. 7 and showing only a part of the connector 1 according to the fifth embodiment as viewed from the x-axis negative direction side. In FIG. 19, the illustration of the seal groove 318, the pin 31b, and the like is omitted. As shown in FIG. 18, the second mold member 31 is a flat plate member that is substantially equivalent to the connection flange portion 313 of the first embodiment, in which the wall portion 310 is omitted and the connection main body portion 312 of the connection portion 311 is omitted. Only have. The second mold member 31 holds the first mold member 30 in the fitting hole 314 and is joined to the housing 2 at the contact surface 31c. A seal member 32 is provided on the surface 317 on the x-axis negative direction side of the second mold member 31.
The seal member 32 is formed of an adhesive, and includes the first mold member 30 (fitting hole 314) inside as viewed from the x-axis direction, and is closer to the x-axis negative direction side than the end surface 300 of the first mold member 30. And surrounds the outer periphery of the covering part A of the covered wires 10a to 10e. The seal member 32 is provided so as to be in close contact with the negative side (surface 300) of the first mold member 30 and to be adhered to the outer periphery of each of the insulators of the covered wires 10a to 10e. The seal member 32 is molded by being filled with an adhesive in a state where the first and second mold members 30 and 31 are installed in the mold. This adhesive has fluidity at least when filled in the mold, and the seal member 32 is formed by removing the mold after solidifying. The material of the adhesive is selected at least that which can be molded, preferably that which can be easily molded. As shown in FIG. 19, the mold (not shown) for forming the sealing member 32 is formed so as to sandwich the covered wires 10a to 10e from both sides in the z-axis direction, and is divided into two in the arrow direction in FIG. The division plane is γ, and the division plane γ is provided parallel to the x-axis direction (perpendicular to the z-axis direction). Since other configurations are the same as those of the first embodiment, the description thereof is omitted.
The first mold member 30 can fix the relative positions of the plurality of covered wires 10a to 10e. Further, by providing a sealing member 32 that is in close contact with the x-axis negative direction end surface 300 of the first mold member 30 and adheres to the outer periphery of each of the insulators of the covered wires 10a to 10e, the covered wires 10a to 10a. It is possible to prevent moisture from entering the exposed portion B from the gap between the outer periphery of 10e and the first mold member 30. Further, when the sealing member 32 is molded using the adhesive as a material, the mold is filled with the fluid adhesive, so that the filling operation of the adhesive can be made efficient and the moldability of the sealing member 32 can be improved. In addition, since the adhesive is filled in the mold when the sealing member 32 is molded, the second mold member 31 does not require the wall 310 for accommodating the adhesive as in the first embodiment. The connection main body 312 of the connection part 311 can also be omitted. Therefore, the shape of the second mold member 31 can be simplified to form a flat plate member. Therefore, the moldability of the second mold member 31 can be improved. In addition, the first and second mold members 30 and 31 can be easily molded by making the mold of the seal member 32 different from the molds of the first and second mold members 30 and 31. In addition, the number of parts can be reduced. That is, in the fifth embodiment, the first and second mold members 30 and 31 are separated from each other. However, since the structure of the entire mold member constituted by the first and second mold members 30 and 31 is simple, The first and second resin materials may be shared and molded as an integral part. In this case, it is possible to mold the entire mold member (before molding the seal member 32) by a single molding, and the workability can be improved. In this case, it is not necessary to seal the gap between the first and second mold members 30 and 31 (between the inner periphery of the fitting hole 314 and the outer periphery of the first mold member 30). It is sufficient to provide it only on the end surface 300 of one mold member 30, thereby reducing the amount of adhesive used.
Furthermore, since the mold release direction of the sealing member 32 is the radial direction (z-axis direction) of each of the covered wires 10a to 10e, compared with the case of releasing in the longitudinal direction (x-axis direction) of the covered wires 10a to 10e. Thus, sliding between the mold and the covered wires 10a to 10e can be suppressed, and damage to the covered wires 10a to 10e due to the mold can be suppressed. As a result, the mold of the seal member 32 can be removed without taking excessive care so as not to impair the insulating properties of the covering portion A, so that the moldability of the seal member 32 can be improved. Note that the second mold member 31 may be omitted. For example, with the first mold member 30 installed in the housing 2 (through hole 220), the gap between the first mold member 30 and the through hole 220 is filled, and each of the insulators of the covered wires 10a to 10e is filled. The sealing member 32 may be formed so as to adhere to the outer periphery.
[Effect of Example 5]
