A device-side terminal that is not connected to an electric wire and has a female connection portion and a device-side housing that accommodates the device-side terminal are sealed.
An apparatus-side terminal is provided with an extension part 53 configured to extend from a female connection part 52 to the side opposite to the wire-side terminal 15 and a seal member 63 is externally fitted to the extension part 53. Then, the seal member 63 is brought into close contact with the inner periphery of the device-side housing 30 so that the gap between the device-side terminal 50 and the inner periphery of the device-side housing 30 is sealed. Thereby, even if the apparatus side terminal 50 is a form which is not connected to an electric wire and has the female connection part 52, between the apparatus side terminal 50 and the apparatus side housing 30 can be sealed reliably.
The present invention relates to a connector for equipment.
As a device connector for connecting electric wires to devices such as motors for electric vehicles, the terminal portion of the electric wires is held by the housing, the housing is fixed to the case of the device, and the electric wires are passed through the mounting holes of the case. There is a structure in which the electric wire side terminal fixed to the terminal is connected to the equipment side terminal in the case.
Connection between terminals is done by bolting, but in order to enable this bolting work, the terminal is provided with a terminal block that exposes the device side terminal outside the case, and after bolting is complete, The terminal block is covered so as to cover the terminal connection portion (see, for example, Patent Document 1).
However, in the above conventional connector for equipment, when connecting or disconnecting an electric wire to or from the equipment, a laborious work of tightening or loosening a bolt and a work of attaching or removing the cover to the terminal block are required. Therefore, workability when connecting / disconnecting wires for maintenance or the like is not good.
Therefore, the electric wire side terminal fixed to the terminal portion of the electric wire is accommodated in the electric wire side housing, and the equipment side housing holding the equipment side terminal is accommodated in the attachment hole provided in the equipment case. A structure in which both terminals are connected by fitting the electric wire side housing to the device side housing is conceivable. According to this structure, there is no need for bolting between terminals, so there is no need to expose the device-side terminal outside the case, and therefore there is no need to cover the terminal with a cover after bolting the terminal. Is excellent.
JP 2002-125348 A
In the structure where the terminals are connected to each other by fitting the housings as described above, if sufficient space cannot be secured on the outer surface side of the case, the wire side terminal is a bus bar bent in an L shape, and the electric wire is connected to the outer surface of the case. It will be routed along. In this case, since the electric wire side terminal which consists of a bus bar makes a male shape, the recessed shape which fits in the state which accommodated this plate-shaped electric wire side terminal, ie, a female shape, is provided in the apparatus side terminal.
When the female terminal is provided with a female shape, there is the following problem in providing a structure for sealing between the device side terminal and the device side housing. Generally, when an electric wire is connected to a terminal, a method is adopted in which a tubular rubber plug is externally fitted to the electric wire and the outer periphery of the rubber plug is brought into close contact with the inner periphery of the housing. However, in the case of a device-side terminal arranged near the device, an electric wire is not necessary, and therefore it is not technically reasonable to employ a waterproof structure in which a rubber plug is externally fitted to the electric wire.
The present invention has been developed in view of the above circumstances, and provides a structure capable of sealing between a device-side terminal that is not connected to an electric wire and has a female connection portion and a device-side housing that accommodates the device-side terminal. It is an object.
According to the first aspect of the present invention, the device-side housing is mounted in a mounting hole formed in the case of the device, the device-side housing is held with a device-side terminal having a female connection portion, and the end of the electric wire is male. While fixing the electric wire side terminal which has a connection part, holding the electric wire side terminal in the electric wire side housing, and fitting the electric wire side housing with the apparatus side housing in the attachment hole, the device side terminal The wire-side terminal is connected by male-female fitting, and the device-side terminal extends from the female connection portion to the opposite side of the wire-side terminal. The extending part of the form was provided, a sealing member was externally fitted to the extending part, and the gap between the device-side terminal and the inner periphery of the device-side housing was sealed by the sealing member.
According to a second aspect of the present invention, in the first aspect of the present invention, the extension portion is fitted with the seal member so as to be in direct contact with the outer peripheral surface thereof, and approaches or abuts the seal member, and the apparatus side. A spacer fitted to the inner periphery of the housing was externally fitted.
The invention of claim 3 is the invention of claim 2, wherein the extending portion is plate-shaped and the inner peripheral sealing surface of the device housing is circular.
It was set as the structure integrated with the said sealing member in the state closely_contact | adhered with respect to the said spacer fixed to the said extension part.
The device side terminal is provided with an extension portion extending from the female connection portion to the side opposite to the wire side terminal, and the inside of the device side terminal and the device side housing is provided by a sealing member fitted to the extension portion. Since the gap with the periphery is sealed, even if the device side terminal is not connected to the electric wire and has a female connection portion, the space between the device side housing can be surely sealed.
[Invention of claim 2]
Since the extension portion is restricted from being displaced in the radial direction by the spacer, the deformation amount of the seal member fitted on the extension portion can be kept uniform in the circumferential direction, and high sealing performance is exhibited. Is done.
[Invention of claim 3]
When the extending portion is plate-shaped and the sealing surface on the inner periphery of the device housing is circular, there is a portion that is greatly separated between the outer surface of the extending portion and the inner peripheral surface of the device housing. For this reason, when the seal member is externally fitted to the extending portion alone, it is necessary to increase the axial dimension of the seal member to prevent unauthorized deformation of the seal member. However, in the present invention, since the seal member is integrated in close contact with the spacer fixed to the extending portion, unauthorized deformation can be avoided even if the seal member is disk-shaped. Thereby, the dimension of the axial direction of a sealing member can be made small, and size reduction can be achieved.
A first embodiment embodying the present invention will be described below with reference to FIGS.
First, the device 80 to which the device connector A of the present embodiment is attached will be described.

Next, the device side connector C will be described. The device-side connector C is a device in which three device-side terminals 50 are held in a device-side housing 30 made of synthetic resin, and is fixed to the mounting hole 82 by a retainer 70 made of synthetic resin.
The device-side housing 30 has an axial line directed upward and downward, three cylindrical portions 31 on the left and right sides, an oval connecting portion 32 that connects the lower ends of the cylindrical portions 31, and a cylindrical portion that extends downward from the connecting portion 32 and each cylinder. An arcuate wall 33 having three left and right semi-cylindrical shapes arranged so as to correspond to the portion 31 is integrally formed.
The outer diameter of the cylindrical portion 31 is the same as the inner diameter of the fitting recess 13 of the electric wire side housing 10, and the male connection portion 17 of the electric wire side terminal 15 is placed in the cylindrical portion 31 on the upper wall portion of the cylindrical portion 31. A slit-like insertion port 34 for entering is formed. In addition, each cylindrical portion 31 has a cavity 35 having a square cross section, and the cavity 35 protrudes upward from a position deviated forward from the axial center of the cylindrical portion 31 in the connecting portion 32. A lance 36 capable of elastic bending in the front-rear direction is provided.
The connecting portion 32 is adapted to be fitted to the inner periphery of an oblong stopper 83 formed at the lower end portion of the attachment hole 82, and a locking rib extending in the circumferential direction is provided on the outer peripheral upper end of the connecting portion 32. 37 is formed. A circumferential seal groove 38 is formed below the locking rib 37 on the outer periphery of the connecting portion 32, and a seal ring 39 is attached to the seal groove 38. The seal ring 39 is formed with a positioning protrusion 40 that protrudes upward. By engaging the positioning protrusion 40 with the positioning recess 41 of the device-side housing 30, the seal ring 39 is positioned in the circumferential direction. And movement in the circumferential direction is restricted. In addition, three attachment grooves 42 that form a semicircular shape coaxial with each cylindrical portion 31 are formed in the front region on the outer periphery of the connecting portion 32 as means for locking the retainer 70.
Three communication spaces 43 communicating with the cavity 35 of the cylindrical portion 31 are formed inside the connection portion 32. On the inner periphery of the communication space 43, a sealing surface 44 is formed that has a circular shape coaxial with the cylindrical portion 31. The inner diameter of the seal surface 44 is larger than the dimension of the cavity 35 in the front-rear direction and is substantially the same as the dimension of the cavity 35 in the left-right direction.
The arc-shaped wall 33 is arranged coaxially with each cylindrical portion 31 and is formed in a direction that opens forward and downward. The radius of curvature of the inner peripheral surface of the arc-shaped wall 33 is the same as the radius of the seal surface 44 of the connecting portion 32. That is, the inner peripheral surface of the arc-shaped wall 33 is continuous with the seal surface 44. In addition, a pair of left and right guide walls 45 are formed on the central arc-shaped wall 33 of the three arc-shaped walls 33 so as to linearly extend forward and rearward from the upper end portions at the left and right end edges. The guide wall 45 is along the lower surface of the connecting portion 32 and has an elongated rectangular shape in the front-rear direction. The inner surface of the guide wall 45 is smoothly continuous with the inner periphery of the arc-shaped wall 33. The front end surface and the rear end surface of the guide wall 45 are flush with the outer periphery of the connecting portion 32. On the other hand, the arc-shaped walls 33 located on both the left and right sides are formed with auxiliary walls 46 that linearly extend forward from the upper end at the edge from the center in parallel to the guide wall 45. Similarly to the guide wall 45, the auxiliary wall 46 extends along the lower surface of the connecting portion 32, has a long and narrow rectangular shape in the front-rear direction, and the inner surface of the auxiliary wall 46 smoothly continues to the inner periphery of the arc-shaped wall 33. The front end surface of 46 is flush with the outer periphery of the connecting portion 32.
The device-side terminal 50 is configured by assembling a terminal main body 51 made of a thick plate material and an elastic contact piece 58 thinner than the terminal main body 51.
The terminal body 51 includes a female connection portion 52 and an extension portion 53 extending downward from the female connection portion 52. The female connection portion 52 has a rectangular tube shape penetrating in the vertical direction, and the front wall 54 of the female connection portion 52 (a plate portion which is a constituent element of the present invention) is engaged with the lance 36 of the cylindrical portion 31. A lance hole 55 to be stopped is formed. The extending portion 53 is elongated in the vertical direction and has a direction in which the thickness direction is the front-rear direction, and is continuous with the front wall 54 (plate portion) of the female connection portion 52. Further, a circular hole 56 penetrating in the front-rear direction is formed at the lower end portion of the extending portion 53, and a cylindrical female screw body 57 projects into the circular hole 56 toward the rear surface side of the extending portion 53. It is fixed.
On the other hand, the elastic contact piece 58 is elongated in the vertical direction as a whole and has a curved shape so that the central part in the vertical direction swells rearward when viewed from the side. A side plate 59 is formed at the upper end of the elastic contact piece 58 so as to extend rearward from the left and right side edges of the elastic contact piece 58 at a right angle, and a locking claw 60 is formed at the upper end edge of each side plate 59. In addition, a cut-and-raised piece 61 perpendicular to the side plate 59 is formed on the front edge of each side plate 59 by cutting a part thereof outward. The elastic contact piece 58 engages the engaging claw 60 with the upper end edge of the side wall 52S of the female connection portion 52, and engages the cut and raised piece 61 with the engagement hole 52H of the side wall 52S of the female connection portion 52. By being stopped, it is attached in a state of being accommodated in the female connection portion 52. The male connection portion 17 of the electric wire side terminal 15 is elastically pinched between the elastic contact piece 58 and the rear wall 52R of the female connection portion 52.
A spacer 62 having a disk shape with the axis line directed in the vertical direction and a seal member 63 having a disk shape coaxial with the spacer 62 are mounted on the extending portion 53 of the device-side terminal 50. The outer diameter of the spacer 62 is the same as the inner diameter of the seal surface 44 of the device-side housing 30, and the outer diameter of the seal member 63 when not elastically deformed is larger than the inner diameter of the seal surface 44. Yes. The spacer 62 and the seal member 63 are integrated with the extending portion 53 (fixed to the extending portion 53) by molding. The molding of the spacer 62 and the molding of the seal member 63 are performed as separate steps, but either may be performed first. By this molding, the seal member 63 is brought into close contact with the upper surface of the spacer 62 so as to be integrated. The centers of the spacer 62 and the seal member 63 are eccentric rearward with respect to the extending portion 53, but are substantially concentric with the female connection portion 52. In addition, the contact region of the seal member 63 in the outer periphery of the extended portion 53 is a constriction in which the cross section is similar to the extended portion 53, that is, a rectangle, the diameter is reduced over the entire periphery, and the four corners are rounded into a taper shape. Part 64 is formed. Note that an adhesive may be applied to the close contact region of the seal member 63 on the outer surface of the extending portion 53.
The device side terminal 50 is inserted into the device side housing 30 from below. The inserted device-side terminal 50 is held by the device-side housing 30 in a state in which the lance hole 55 is locked to the lance 36 to prevent removal (falling). In this state, the female connection part 52 is accommodated in the cavity 35 of the cylindrical part 31, and the extension part 53 passes through the communication space 43 of the connection part 32 and is positioned in front of the arc-shaped wall 33. At this time, the lower end of the extending portion 53 is positioned slightly above the lower end of the arc-shaped wall 33. Further, the spacer 62 abuts against the seal surface 44 over the entire circumference, and as a result of this abutment, the seal member 63 fixed to the extending portion 53 has a backlash in the front-rear and left-right directions relative to the seal surface 44. Restricted to play. Therefore, the seal member 63 is kept in a state of being in close contact with the seal surface 44 over the entire circumference.
The retainer 70 is made of synthetic resin, and is formed by integrally molding an upper surface wall 71 and four wall portions 73 and 75 extending downward from the lower surface of the upper surface wall 71 at a right angle and in parallel with each other. In the upper surface wall 71, three cutouts 72 that are opened rearward and whose back end (front end) is a semicircular arc are formed so as to correspond to the cylindrical part 31 of the device-side housing 30. Of the four wall portions 73 and 75, the central two wall portions are partition walls 73 that partition between the three cutout portions 72. A bending locking piece 74 is formed at the upper end of the partition wall 73. Further, the two wall portions located at both the left and right ends are protective walls 75.
When attaching the device connector A of the present embodiment to the device 80, first, the device-side connector C is assembled to the shield case 81. At the time of assembly, the device side housing 30 is dropped from above (from the outer surface side of the shield case 81) into the mounting hole 82, and the locking rib 37 is brought into contact with the stopper 83 from above so that the device side housing 30 is dropped. To regulate. In this state, the attachment groove 42 at the lower end of the connecting portion 32 passes through the attachment hole 82 and is positioned slightly below the lower surface (inner surface) of the shield case 81, and the arcuate wall 33 also penetrates the attachment hole 82. Located inside the shield case 81.
Thereafter, the retainer 70 is assembled to the device-side housing 30 from the front inside the shield case 81, and the notch 72 is fitted into the mounting groove 42. The assembled retainer 70 is prevented from being pulled out by a flexure locking piece 74, and is restricted from moving in any direction of up / down / left / right / front / rear with respect to the device-side housing 30. It will be in the state of contact. As a result, the device-side housing 30 is prevented from coming out upward with respect to the shield case 81.
In a state where the retainer 70 is assembled to the device-side housing 30, the device direct connection terminal 85 is sandwiched between the protective wall 75 and the partition wall 73 or between the partition walls 73, and left and right with the axis in the front-rear direction as a fulcrum. Displacement in the direction (including rotation and tilt) is restricted. In addition, lower end portions of the device-side terminal 50 that are located in front of the arc-shaped wall 33 are separated from each other by the partition wall 73. Similarly, the apparatus direct connection terminals 85 are also isolated by the partition wall 73.
In the state where the device-side housing 30 is assembled to the shield case 81 in this way, the vertical portions 85b of the device direct connection terminals 85 abut or approach the front surfaces of the extending portions 53 of the corresponding device-side terminals 50, respectively. The bolt hole (not shown) of the apparatus direct connection terminal 85 and the female screw body 57 of the apparatus side terminal 50 correspond to each other coaxially. In this state, when the bolt 86 is passed through the bolt hole from the front and screwed into the female screw body 57 and tightened, the device-side terminal 50 is connected to the device direct connection terminal 85.
Thereafter, the electric wire side connector B is assembled from the outside (upper side) of the shield case 81 and engaged with the device side connector C. At the time of fitting, each fitting part 12 is fitted in the mounting hole 82 and is fitted so as to cover the corresponding cylindrical part 31. Then, the male connection portion 17 of the device side terminal 50 is inserted into the cylindrical portion 31 and enters the female connection portion 52 of the device side terminal 50, and the elastic contact piece 58 is against the male connection portion 17. Elastic contact. Thereby, the electric wire side terminal 15 and the apparatus side terminal 50 are connected.
In addition, the wire-side connector B is fixed to the outer surface of the shield case 81 by screwing and tightening a bolt 87 penetrating the shield shell 22 and the wire-side housing 10 into the female screw hole 88 of the shield case 81. The The shield shell 22 is connected to the shield case 81 so as to be conductive.
Further, in a state where the device connector A is attached to the device 80, the space between the mounting hole 82 and the device side connector C is waterproofed by a seal ring 39 attached to the outer periphery of the device side housing 30, and the wire side connector B and the mounting hole 82 is waterproofed by a seal ring 14 mounted on the outer periphery of the fitting portion 12. Therefore, there is no possibility that liquid outside the shield case 81 enters the shield case 81 through the attachment hole 82, and there is no possibility that oil in the shield case 81 leaks out of the shield case 81 through the attachment hole 82. Water immersion from the outside of the shield case 81 to the fitting portion between the wire side connector B and the device side connector C is also waterproofed by the two seal rings 14 and 39.
Further, since the inside of the device-side housing 30 faces the shield case 81, the oil in the shield case 81 passes through the gap between the device-side housing 30 and the device-side terminal 50, and the wire-side terminal 15 and the device-side terminal. However, in the present embodiment, the outer periphery of the device-side terminal 50 may be intruded into the wire 24 through the gap between the wire-side housing 10 and the wire-side terminal 15. Since the seal member 63 is attached to the cable, there is no risk of oil intrusion into the connecting portion between the terminals 15 and 50 and the electric wire 24.
As described above, in the present embodiment, the device-side terminal 50 is provided with the extending portion 53 in a form extending from the female connection portion 52 to the side opposite to the wire-side terminal 15, and the extending portion 53 is externally provided. Since the gap between the outer periphery of the device-side terminal 50 and the inner periphery of the device-side housing 30 is sealed by the fitted seal member 63, the device-side terminal 50 is not connected to the electric wire and has a female connection portion. Even so, the gap between the device-side terminal 50 and the device-side housing 30 can be reliably sealed.
Further, a seal member 63 is externally fitted to the extended portion 53 so as to be in direct contact with the outer peripheral surface thereof, and a spacer 62 that is adjacent to the seal member 63 and fitted to the inner periphery of the device-side housing 30 is externally attached. The outer periphery of the spacer 62 is in contact with the seal surface 44 of the device-side housing 30 over the entire periphery, so that the displacement of the extending portion 53 in the radial direction (front / rear / left / right direction) is regulated. ing. Therefore, the deformation amount of the seal member 63 (elastic adhesion force to the seal surface 44) is kept uniform and constant in the circumferential direction, and high sealing performance is exhibited.
In the present embodiment, the extending portion 53 has a plate shape and is decentered forward, whereas the inner peripheral sealing surface 44 of the device-side housing 30 has a circular shape. And the seal surface 44 are greatly separated. For this reason, when trying to make the structure in which the seal member 63 is externally fitted to the extending portion 53 alone, the size of the seal member 63 in the axial direction (vertical direction) is increased to improper deformation (elasticity in the radial direction) of the seal member 63. It is necessary to prevent deformation other than bending. However, in this embodiment, since the spacer 62 is fixed to the extension portion 53 and integrated with the seal member 63 in close contact with the upper surface of the spacer 62, it is illegal to make the seal member 63 disk-shaped. Deformation (deformation in which the upper and lower surfaces of the seal member 63 are curved) can be avoided. In other words, the size of the seal member 63 in the axial direction is reduced to reduce the size, and as a result, the entire device-side connector C is reduced in size.
In the second embodiment, the mounting configuration of the spacer 90 and the seal member 91 to the extending portion 53 is different from that of the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.
In the first embodiment, both the spacer 62 and the seal member 63 are directly fitted to the extended portion 53, whereas in the second embodiment, only the spacer 90 is directly fitted to the extended portion 53. The seal member 91 has a ring shape that is fitted in a seal groove 92 formed on the outer periphery of the spacer 90 and is attached to the outer periphery of the spacer 90. As for the spacer 90, in the second embodiment, the molded one is fixed to the extending portion 53, but may be integrated with the extending portion 53 by molding. Similarly, the seal member 91 is not limited to a form in which the molded seal member 91 is mounted in the seal groove 92, and the seal member 91 may be integrated with the outer periphery of the spacer 90 by molding.
(1) In the first embodiment, the spacer is disposed so as to contact the seal member. However, according to the present invention, the spacer may not be provided. In this case, if the dimension of the seal member in the axial direction is increased, it is possible to prevent the seal member from being illegally deformed.
(2) In the first embodiment, the spacer is disposed so as to contact the seal member. However, according to the present invention, the seal member and the spacer may be disposed so as to be in non-contact and close to each other.
(3) In the above embodiment, the seal member is in close contact with the upper surface of the spacer. However, according to the present invention, the seal member may be in close contact with the lower surface of the spacer. In addition, a seal member may be sandwiched between two spacers, and two seal members may be disposed on both upper and lower sides of one spacer.
(4) In the above embodiment, the spacer and the seal member are integrated by molding. However, according to the present invention, the molded spacer and the seal member are assembled to the extension portion. It may be fixed with an adhesive.
(5) In the above embodiment, the spacer is fixed to the extending portion by molding. However, according to the present invention, a molded spacer may be externally fitted to the extending portion and fixed with an adhesive.
(6) In the above embodiment, the seal member is externally fitted to the extending portion by molding.
