The present invention relates to an electrical connector and an electrical connector assembly for electrically connecting a terminal portion of a signal transmission medium to a conductive path formed on a surface of a product housing.
In general, in various electronic devices or electric devices such as mobile phones, terminal portions of various signal transmission media composed of fine coaxial cables, flexible wiring boards, printed wiring boards, etc. are connected to the printed wiring board side using electrical connectors. (See, for example, Patent Document 1 below). The electrical connector is used to connect the terminal portion of the signal transmission medium to a predetermined wiring pattern (circuit), and is usually attached to the inside of the product housing 1 as shown in FIG. 20, for example. A receptacle connector 3 is mounted on the circuit board 2, and a plug connector 5 in which a terminal portion of a signal transmission medium 4 made of a thin coaxial cable or the like is connected is fitted to the receptacle connector 3. The functions of the electrical connectors 3 and 5 used at this time are to transmit a necessary information signal through the signal line and to connect the ground shield signal to the ground circuit through the shield line.
On the other hand, in recent years, electronic devices and the like have been rapidly reduced in size and thickness, and accordingly, electrical connectors are also being reduced in height and cost. There is a strong demand to simplify the configuration of No. 5. In order to omit the receptacle connector 3, it is conceivable to directly solder the connecting leg portion of the plug connector 5 to the conductive path on the product housing 1, but the product housing 1 is made of a resin molding material. It has low heat resistance and cannot be directly soldered or mounted on electronic products. Accordingly, in any of the electrical connectors normally used, one electrical connector (receptacle connector) 3 is mounted on the printed wiring board 2 having a wiring pattern, and the other electrical connector 3 is mounted on the other electrical connector 3. It has a basic configuration in which an electrical connector (plug connector) 5 is fitted. And it is becoming increasingly difficult to achieve a significant reduction in profile and cost due to such basic configuration constraints.

Hereinafter, a thin coaxial cable is used as a signal transmission medium, and the electric cable is configured so as to be directly fitted by being inserted into the product housing of the electronic device from the upper side and horizontally moved. An embodiment when the present invention is applied to a connector will be described in detail with reference to the drawings.
[Overall structure of electrical connector assembly]
That is, the plug connector 10 according to the first embodiment of the present invention shown in FIG. 1 to FIG. 15 is a cellular phone having a predetermined electronic circuit as a terminal portion of a thin coaxial cable SC as a signal transmission medium. The product housing MF is configured to be electrically connected to the wiring pattern conductive path CP formed on the outer surface of the wall portion of the product housing MF constituting the electronic device. A wiring pattern conductive path CP that constitutes a part of an antenna and various circuits is formed on the outer surface of the wall portion by printing or the like. In addition, the product housing | casing MF described in FIGS. 2-19 represents the partial shape excerpting.
A pair of fitting connection holes MFa and MFa are formed in the wall portion of the product casing MF so as to pass through the wall portion of the product casing MF, and the pair of fitting connections A fitting and fixing portion MFb formed in a beam shape is defined between the holes MFa and MFa. And the connection leg part 10B which protrudes from the connector main-body part 10A of the plug connector 10 is horizontally moved from the upper side with respect to the fitting connection hole MFa and MFa provided in the wall part of the product housing | casing MF. It is made the structure fitted by.
That is, the connector main body portion 10A of the plug connector 10 is connected with a terminal portion of a fine coaxial cable SC as a signal transmission medium, and the plug connector 10 to which the fine coaxial cable SC is connected is first shown in FIGS. 10 is arranged so as to face the upper side of the fitting fixing part MFb. Then, the entire plug connector 10 disposed on the upper side is lowered in a direction substantially orthogonal to the outer surface of the wall portion of the product housing MF, as shown in FIGS. 12 and 14A. As described above, after the connecting leg portion 10B of the plug connector 10 is inserted into the fitting connecting hole MFa described above, the fitting fixing portion MFb is moved by moving along the outer surface of the product housing MF. Is brought into a fitted state.
Thus, in the fitting state in which the plug connector 10 is inserted and moved into the fitting connection hole MFa of the product housing MF, the terminal portion of the thin coaxial cable SC is connected to the wiring pattern conductive path CP via the plug connector 10. In the following description, the direction in which the plug connector 10 is inserted is referred to as “downward”, and the removal direction in which the plug connector 10 is removed is referred to as “upward”. In the plug connector 10, the end edge to which the end of the thin coaxial cable SC is connected is referred to as a “rear end edge”, and the opposite end edge is referred to as a “front end edge”. The direction from the “rear edge” to the “front edge” is “front”, and the opposite direction is “rear”. Further, the direction perpendicular to the “vertical direction” and “front-rear direction” is defined as “left-right direction”.
[Product housing]
Here, as described above, the fitting connection hole MFa formed in the wall portion of the product housing MF is formed from a pair of through holes arranged adjacent to each other so as to be substantially line-symmetric. The end edge portion on the side where the fitting connection holes MFa and MFa are adjacent to each other is formed on both side edge portions of the fitting fixing portion MFb described above. That is, the fitting and fixing portion MFb formed in a beam shape extending in the front-rear direction as described above has both side edges in the plate width direction orthogonal to the extending direction on the wall portion of the product casing. It is made into the structure which forms the inner edge part of the fitting connection hole MFa and MFa which consist of the long hole penetrated.
Each of the fitting connection holes MFa is a long hole extending in an elongated shape so as to correspond to the front-rear direction of the plug connector 10 described above, and corresponds to the rear side and the front side of the plug connector 10 respectively. An insertion hole MFa1 and a fitting hole MFa2 made of long holes having different opening shapes are provided so as to communicate with each other in the front-rear direction. The long hole constituting the insertion hole portion MFa1 disposed on the rear side of the long hole is set so that the longitudinal direction of the long hole is the front-rear direction, and in the front-rear direction of the connecting leg portion 10B of the plug connector 10 It has a long diameter extending in the front-rear direction so as to allow movement.
The long hole constituting the insertion hole MFa1 has a short diameter extending in the left-right direction. The short diameter is inserted through the entire connecting leg 10B of the plug connector 10 described above. It is formed relatively wide to the extent possible. Due to this relatively wide minor diameter, the connecting leg portion 10B of the plug connector 10 described above is arbitrarily inserted or removed through the insertion hole MFa1.
On the other hand, the long hole constituting the fitting hole MFa2 disposed on the front side of the insertion hole MFa1 has a long diameter extending in the front-rear direction, similar to the above-described insertion hole MFa1. Thus, the connecting leg 10B of the plug connector 10 is configured in a similar manner in that the connecting leg 10B can be moved in the front-rear direction, but has a shorter diameter than the insertion hole MFa1. . The short diameter of the fitting hole MFa2 is formed such that only the intermediate portion in the height direction of the connecting leg portion 10B can be inserted, and the wide lower end portion of the connecting leg portion 10B cannot be inserted. It has become. Therefore, only the intermediate portion in the height direction of the connecting leg portion 10B inserted from the insertion hole portion MFa1 described above can be inserted into the fitting hole portion MFa2. The connecting leg 10B inserted into the fitting hole MFa2 through the insertion hole MFa1 is allowed to move in the longitudinal direction (front-rear direction) of the long hole constituting the fitting hole MFa2. On the other hand, it does not separate from the fitting hole MFa2 in the height direction and come out.
More specifically, the opening edge portion of the fitting connection hole MFa composed of the long holes constituting the insertion hole portion MFa1 and the fitting hole portion MFa2 is elongated corresponding to the front-rear direction of the plug connector 10. The outer edge in the left-right direction of the opening edge is formed as a straight common edge extending continuously from the insertion hole MFa1 to the fitting hole MFa2. On the other hand, the inner edge of the fitting connection hole MFa2, that is, the end edge forming the outer shape of the fitting fixing part MFb described above is substantially perpendicular to the boundary with the insertion hole MFa1. A fixed main plate MFb1 having a shape slightly protruding outward in the left-right direction is provided on the front side portion of the fitting fixing portion MFb. And the connector main-body part 10A of the plug connector 10 is finally made into a fitting state with respect to this fixed main board MFb1.
In addition, the opening shape of each fitting connection hole MFa formed of the insertion hole portion MFa1 and the fitting hole portion MFa2 is symmetric in both the inner and outer side edges, but is asymmetrically different. Alternatively, it may have a rotationally asymmetric shape. In that case, corresponding to the rotationally asymmetric opening shape in the fitting connection hole MFa, the connection leg portion 10B of the plug connector 10 inserted into the fitting connection hole MFa is also rotationally asymmetric, as will be described later. If the projected shape in the fitting direction of the leg portion 10B is a rotationally asymmetric shape in a horizontal plane perpendicular to the insertion fitting direction (downward), the connecting leg portion 10B of the plug connector 10 is inserted into the fitting connecting hole MFa. When the plug connector 10 is mistakenly arranged on the opposite side in the rotational direction when mating, the mating operation itself becomes impossible, so that erroneous mating can be prevented.
Furthermore, on the front and back surfaces of the fixed main plate MFb1 provided on the front side of the fitting fixing portion MFb that defines the fitting connection holes MFa and MFa in this way, An interference avoidance recess MFb2 is provided in a portion between the pair of fitting holes MFa2 and MFa2 described above. The interference avoidance recess MFb2 is separated from the connector main body 10A when the plug connector 10 moves in the longitudinal direction of the fitting connection hole MFa, that is, the extending direction of the fitting fixing portion MFb. However, a detailed structure will be described later as a structure for avoiding frictional interference.
On the other hand, as described above, the terminal portions of the signal conductive path CPa and the ground conductive path CPb constituting the wiring pattern conductive path CP are formed on the surface constituting the outer exposed surface of the front and back surfaces of the product housing MF. Has been. The terminal portions of these wiring pattern conductive paths CP are arranged so as to extend in the front-rear direction in a region including the fitting fixing portion MFb which is a region between the pair of fitting connection holes MFa and MFa described above. . The terminal portions of the signal conductive path CPa and the ground conductive path CPb are in the front-rear direction with respect to the fixed main plate MFb1 constituting the front side portion of the fitting fixing portion MFb, that is, the inner side portion of the fitting hole MFa2. The arrangement relationship is such that they are spaced apart from each other and face each other. In addition, the product housing | casing said by this invention does not necessarily need to be formed in a box shape, and should just comprise a part of wall surface which comprises electronic devices, such as a mobile telephone.
[About plug connectors]
In addition, as described above, the plug connector 10 is fitted to the fixed main plate MFb1 that is horizontally moved and constitutes the front portion of the fitting fixing portion MFb after being inserted into the fitting connecting hole MFa from above. The terminal portion of a thin coaxial cable SC as an example of a signal transmission medium is connected to the rear end edge of the connector main body 10A of the plug connector 10. Hereinafter, each end edge portion of the fitting connection hole MFa corresponding to the rear end edge portion and the front end edge portion of the plug connector 10 will be similarly referred to as a rear end edge portion and a front end edge portion.

The elastic arm portions constituting the ground conductive terminals 13 and 13 formed so as to branch into the forked shape are left and right sandwiching the thin coaxial cable SC and the signal transmission conductive terminal (signal contact) 12. The contact portions 13a and 13a (shown in the figure) are disposed at the outer positions on both sides, and have a concave shape at the leading end portion on the extending side (rear end side) of the elastic arm portion of the ground conductive terminals 13 and 13. 15). Each of the contact portions 13a is configured to be bifurcated in both left and right directions and elastically displaced in the vertical direction about a swinging fulcrum 13b formed on the proximal end near the front end surface of the shell main body portion 14a. ing. When the plug connector 10 is fitted to the product housing MF, the contact portion 13a of the ground conductive terminal 13 is connected to the ground conductive path CPb formed on the outer surface of the product housing MF. It comes in contact from the upper side.
At this time, the connecting member 14e that connects the shell main body portion 14a and the shell lid portion 14b does not face the rocking fulcrum 13b of the ground conductive terminal (ground contact) 13 described above in the bending direction of the connecting member 14e. Is provided.
With such a configuration, when the connecting member 14e is bent so that the shell lid portion 14b is attached to the shell main body portion 14a, the influence of the bending of the connecting member 14e is the ground conductive terminal (ground contact) 13. Therefore, deformation of the ground conductive terminal 13 is avoided. Therefore, depending on the position of the connecting member 14e, the position of the swing fulcrum 13b can be changed as appropriate.
In addition, the shell main body portion 14a and the shell insertion portion 14c described above are arranged on the outer portions of the ground conductive terminals 13 and 13 on both sides in the left-right direction so as to form a standing wall. The insertion portion 14c is formed of a plate-like member that extends downward from the shell main body portion 14a so as to form a cantilever beam. The shell insertion portion 14c constitutes a part of the connecting leg portion 10B described above. If the connecting leg portion 10B is formed integrally with the shield shell 14, the shield shell 14 is molded. At the same time, the connecting leg portion 10B is efficiently molded, so that productivity is improved.
Further, the lower end portion of the shell insertion portion 14c has a sandwiching support portion 14h made of an inner side bent piece that is bent at a substantially right angle and protrudes toward the inner side (center side) in the left-right direction. Is provided. The sandwiching support portion 14h extends from the inner edge portion of the fitting connection hole MFa2 to the back surface (lower surface) side of the fitting fixing portion MFb, and lowers both end edge portions of the fixing main plate MFb1 of the fitting fixing portion MFb. It is formed in a shape that covers from the side, and it projects inwardly so that it can be inserted into the aforementioned insertion hole MFa1 and cannot be inserted into the fitting connection hole MFa2. Width) is limited and adjusted. When the shell insertion portion 14c inserted into the insertion hole MFa1 moves forward to the front fitting coupling hole MFa2, the clamping support portion 14h is pressed against the back surface of the fitting fixing portion MFb. It is made a joint state.
The sandwiching support portion 14h provided at the lower end portion of the shell insertion portion 14c is disposed so as to be substantially parallel to a position substantially directly below the ground conductive terminal (ground contact) 13 described above. 14h and 13 are arrange | positioned in the positional relationship which mutually faces in an up-down direction. The distance between the general surfaces of the members 14h and 13 at this time is set to be slightly larger than the thickness of the product housing MF, and the distance between the sandwiching support portion 14h and the ground conductive terminal 13 is set. The wall portion of the product housing MF described above is configured to enter the space portion formed without any trouble.
At this time, movement guide portions 14i and 14i formed so as to be inclined downward are provided at front and rear end edge portions of the above-described sandwiching support portion 14h. The inclined surfaces of these movement guide portions 14i, 14i have a guiding action with respect to the edge corner portion of the fixed main plate MFb1 constituting the front side portion of the fitting fixing portion MFb, and are inserted as described above. When the shell insertion portion 14c moves in the front-rear direction between the hole portion MFa1 and the fitting connection hole MFa2, the distal end portion of the sandwiching support portion 14h does not interfere with the edge corner portion of the fixed main plate MFb1, It can be inserted smoothly.
Furthermore, the clamping support portion 14h of the connecting leg 14 described above is engaged and locked in an upwardly convex shape at a substantially central portion in the longitudinal direction that is the extending direction of the clamping support portion 14h. A portion 14j is projected. (See FIG. 15) The engagement lock portion 14j is formed of a so-called dimple that is pressed so as to form a protruding shape on the sandwiching support portion 14h that forms a part of the connecting leg portion 14 described above. The front and rear have inclined engaging surfaces facing both the extending direction (front-rear direction) of the portion 14h. Further, the engagement lock portion 14j is arranged to face the lower side of the ground conductive terminal (ground contact) 13 in the thickness direction of the product housing MF, and the top portions of these engagement lock portions 14j. And the contact portion 13a of the ground conductive terminal 13 are set to be slightly smaller than the thickness of the product housing MF. Accordingly, the product housing MF is sandwiched in the thickness direction between the engagement lock portions 14j and the contact portion 13a of the ground conductive terminal 13. The structure and operation of the engagement lock portion 14j will be described later.
Thus, in the present embodiment, the fitting fixing portion MFb and the fitting connection hole MFa of the product housing MF are formed so as to be elongated in the front-rear direction, and the fitting connection hole MFa of the product housing MF is formed. The connecting leg portion 10B of the plug connector 10 inserted inside is allowed to reciprocate in the longitudinal direction (front-rear direction) which is the major axis direction of the long hole.

And a contact portion 12d of the signal contact 12, which will be described later, are configured to sandwich the fixed main plate MFb1 constituting the front side portion of the fitting fixing portion MFb provided in the product housing MF in the thickness direction. Yes. The connecting leg 10B of the plug connector 10 can be moved backward from the fitting hole MFa2 disposed on the front side of the fitting connecting hole MFa toward the insertion hole MFa1 on the rear side. The connecting leg portion 10B of the plug connector 10 and the ground conductive terminal 13 are separated from the fixed main plate MFb1 of the fitting fixing portion MFb in the product housing MF and can be removed.
As described above, in the present embodiment, the single plug connector 10 is directly fitted to the fitting fixing portion MFb provided on the wall portion of the product housing MF. In the fitted state of the plug connector 10, the signal transmission conductive terminal (signal contact) 12 and the ground conductive terminal (signal contact) 12 are connected to the wiring pattern conductive path CP such as the signal transmission wiring pattern formed on the surface of the product housing MF. Each contact portion of the ground contact 13 is brought into contact. Therefore, the electrical connection of the signal transmission medium is performed with a simple configuration without interposing a conventionally used circuit board or other electrical connector to be mated with the circuit board. The number of points can be reduced and solder mounting can be omitted, resulting in a significant cost reduction. In addition, the variation in impedance is suppressed by reducing the number of electrical connection points. The reliability of electrical connection is improved by improving the problems such as variations.
The final fixing of the entire plug connector 10 is performed by the product leg MF of the connector main body 10A and the ground conductive terminal (ground contact) 13 sandwiching the product housing MF in the thickness direction. Therefore, even if the plug connector 10 is repeatedly fitted to and removed from the product housing MF, the fitting connectivity of the plug connector 10 to the product housing MF is maintained well over a long period of time.
Further, in the present embodiment, a locking lock portion MFc that receives the engagement locking portion 14j of the above-described sandwiching support portion 14h is recessed in the rear surface side (lower surface side) of the product housing MF. The locking lock portion MFc is formed so as to cut out a part of the inner end edge of the fixed main plate MFb1 constituting the front side portion of the fitting fixing portion MFb, that is, the front side fitting hole portion MFa2. As described above, the connecting leg portion 10B of the plug connector 10 is provided in the holding support portion 14h when the connecting leg portion 10B is moved forward from the rear side insertion hole portion MFa1 to the front side fitting hole portion MFa2. The engagement lock part (engagement lock part) 14e is dropped into a stepped shape inside the engagement lock part MFc so as to be in a fitted state.
On the other hand, the engagement lock portion 14j in the present embodiment has the front and rear inclined engagement surfaces facing both in the front-rear direction as described above, and the engagement lock portion 14j is the engagement lock portion as described above. When the entire plug connector 10 is shifted in either the front or rear direction after being dropped into the MFc, any of the inclined engagement surfaces provided on the front and rear sides of the engagement lock portion 14j is as described above. The connector main body portion 10A is brought into contact with the inner wall surface of the locking lock portion MFc, whereby the connector main body portion 10A is locked in the front-rear direction, and the entire plug connector 10 is held stationary. In addition, the locking action to the front side with respect to the plug connector 10 is also performed by the connection leg portion 10B coming into contact with the front end edge of the above-described front-side fitting hole MFa2.
In this way, if the engagement lock portion 14j provided in the fitting fixing portion MFb of the connecting leg portion 10B is fitted to the locking lock portion MFc formed by the hole portion of the product housing MF, a configuration is adopted. The fitting property between the engagement lock portion 14j and the engagement lock portion MFc is improved, and the plug connector 10 is reliably held. Further, if the engagement lock portion 14j is formed of dimples as in the present embodiment, the engagement lock portion 14j can be easily formed.
Furthermore, in the present embodiment, in particular, the ground conductive terminal (ground contact) 13 is connected to the wiring pattern conductive path CP provided in the product housing MF, as shown in FIG. 7 and FIG. When the contact portion 13a contacts, the elastic arm portion of the ground conductive terminal 13 floats upward from the surface of the product housing MF due to the elastic spring force of the ground conductive terminal 13, and the upper surface of the product housing MF And a bottom surface of the insulating main body 11a, which is a surface facing the upper surface of the product housing MF, and a top surface of the product housing MF and an upper surface of the product housing MF. A gap is formed between the elastic arm portion of the ground conductive terminal 13, which is a surface facing the surface.
[Signal contact]
Further, the signal transmission conductive terminal (signal contact) 12 in the present embodiment is attached to the insulating main body 11a of the insulating housing 11 by press-fitting or insert molding or the like, and as particularly shown in FIG.

In such a configuration, the contact portions 12d, 12d, 12d, 12d, and 12b are formed by elastic displacement action of the two cantilevered arm-shaped members constituting the signal transmission conductive terminal (signal contact) 12 and the ground conductive terminal (ground contact) 13. Although moments occur around 13a, both moments cancel each other because they are in opposite directions. As a result, the plug connector 10 is maintained in a stable state during and after the fitting operation.
Further, the contact portion 12d of the signal transmission conductive terminal (signal contact) 12 is similar to the contact portion 13a of the ground conductive terminal (ground contact) 13 described above, and the engagement lock portion 14j of the holding support portion 14h.

With such a configuration, the entire plug connector 10 inserted and fitted into the product housing MF includes the engagement lock portion 14j of the holding support portion 14h and the signal transmission conductive terminal (signal contact) 12. It is stably held by the clamping force between the contact portion 12d and the contact portion 13a of the ground conductive terminal (ground contact) 13.
Furthermore, in the present embodiment, an engagement lock portion 14j is disposed between the contact portion 12d of the signal transmission conductive terminal 12 and the contact portion 13a of the ground conductive terminal 13 in the cross-sectional direction (front-rear direction) in FIG.
