JP 2011-249076 A

  Since the connector includes a plurality of housings, a fixed housing and a movable housing, the size of the connector increases as a whole. Further, in order for the movable part to sufficiently absorb the vibration of the substrate or the like, the spring piece of the movable part needs to be soft and elastically deformable. In this case, it is necessary to increase the spring length, but the terminal may be enlarged as a whole as the spring length is increased.

  The present invention has been made based on the background described above, and an object of the present invention is to provide a small connector having a terminal that can sufficiently absorb vibration of a substrate or the like and maintain a conductive contact with a connection object.

In order to achieve the above object, the present invention is configured as follows.
That is, the present invention includes a housing having a fitting chamber with a pin-shaped connection object, and a contact contact portion disposed in the fitting chamber and in electrical contact with the pin-shaped connection object inserted into the fitting chamber. The coil spring is arranged in the mating chamber and has a coil spring shape along the direction of the axis of the pin-shaped connection object, and elastically supports the contact contact portion so that it can be displaced in the three-dimensional direction inside the mating chamber. A connector including a terminal having a movable piece is provided.

  Since the terminal has the wound spring-like movable piece, the spring piece can be made compact as a whole while increasing the spring length. Therefore, the wound spring-like movable piece can be softly and elastically deformed. Furthermore, one housing has a fitting chamber that accommodates both the wound spring-like movable piece and the contact point contact portion, so that it has a plurality of housings and a terminal is fixed to the plurality of housings. And a small connector.

  The wound spring-like movable piece of the present invention can form a polygonal shape in the winding direction.

  By doing so, it is possible to obtain a terminal that can easily fit into the fitting chamber of the housing. Therefore, it can be set as a more compact connector.

  The wound spring-like movable piece of the present invention can have a plurality of divided movable pieces that are branched by slits that extend along the winding direction.

  By doing so, since the wound spring-like movable piece can be constituted by a plurality of thin divided movable pieces, the wound spring-like movable piece can be softly and elastically deformed as a whole.

  The slit of the present invention may be provided across a plurality of corners of the wound spring-like movable piece forming the polygonal shape.

  By doing so, a long slit can be formed long and the split movable piece can be made longer, so that the wound spring-like movable piece can be softly and elastically deformed.

  The wound spring-like movable piece of the present invention and the contact point contact portion may be disposed along the insertion / extraction direction of the connection object inside the fitting chamber.

  By carrying out like this, a terminal can be reduced in size in the crossing direction with respect to the insertion / extraction direction of a connection target object. Thereby, the occupation area of the whole connector can be made small.

  The terminal of the present invention has a board connecting portion disposed in the housing and a base extending from the board connecting portion to the fitting chamber of the housing, and the wound spring-like movable piece is one end connected to the base. The side is located in the upper part of the fitting chamber, and the contact contact part is connected to the other end side of the wound spring-like movable piece and is located in the lower part of the fitting chamber.

  By making the terminal into such a shape, the board connecting portion that is conductively connected to the board is secured, and the occupying area on the board where the wound spring-like movable piece and the contact contact portion are arranged vertically inside the fitting chamber Can be easily manufactured from a single metal plate.

  The displacement load at which the wound spring-like movable piece of the present invention is displaced in the insertion / removal direction of the connection object is smaller than the load at which the contact contact portion is displaced in the insertion / removal direction from the normal contact position with the connection object. Can be.

  In this way, even if the connection object is elastically displaced along the insertion / extraction direction with respect to the housing, the coil spring-like shape is formed before the contact contact portion is displaced from the normal contact position with the connection object. The movable piece is elastically deformed in the insertion / extraction direction. Therefore, the contact contact portion can follow the connection object and suppress the occurrence of sliding contact.

  The inner surface of the fitting chamber of the present invention may have a polygonal cross-section, and the wound spring-like movable piece may have a wound spring-like movable portion having a polygonal shape along the inner surface of the fitting chamber.

  By making the inner surface of the fitting chamber into a polygonal cross section, the fitting chamber can be formed by efficiently utilizing the occupied volume of the housing. In addition, since the wound spring-like movable piece has a shape along the inner surface of the fitting chamber, it can be accommodated in the fitting chamber in a compact manner, so that the entire connector can be further downsized.

  A plurality of terminals according to the present invention are provided, the housing has a plurality of fitting chambers, and each fitting chamber has a contact contact portion and a wound spring-like movable piece each having one terminal. Can be.

  By doing so, it is possible to ensure a space in which each of the wound spring-like movable pieces is sufficiently elastically deformed while reliably preventing a short circuit with another terminal. In addition, a small connector can be provided with a plurality of terminals.

  According to the connector of the present invention, it is possible to maintain a conductive contact between the contact contact portion and the connection object by absorbing vibrations of the substrate or the like by the wound spring-like movable piece that is soft and elastically deformed, and to make a small connector.

As shown in FIGS. 1 to 8, the connector 1 includes a housing 4 and a plurality of terminals 2 held by the housing 4.

〔housing〕
As shown in FIGS. 1 and 2, the housing 4 is formed as a box-shaped molded body made of an electrically insulating resin. The housing 4 includes a lower wall portion 4d, an upper wall portion 4c, a side wall portion 4e, a back wall portion 4f, a partition wall 4a, and a plurality of fitting chambers 4b.

When the pin-like terminal 3a of the mating connector 3 is inserted from the insertion hole 4d1 provided in the lower wall portion 4d, the contact contact portion 8 of the terminal 2 is pressed upward by the pin-like terminal 3a. The spring-like movable piece 6 of the terminal 2 is also elastically deformed upward so that it can be lifted. However, the elastic deformation is stopped when the wound spring-like movable piece 6 comes into contact with the upper wall portion 4 c, and the pin-like terminal 3 a can be inserted into the connection chamber 8 f of the contact contact portion 8.

  As shown in FIGS. 7 and 8, the side wall part 4 e connects the upper wall part 4 c and the lower wall part 4 d, and one side wall part 4 e is provided on each end in the width direction X of the housing 4. Reinforcing metal fittings 4e1 for soldering and fixing the housing 4 to the substrate P are attached to each side wall 4e. In addition, a fixing groove 4h for fixing the terminal 2 by inserting the fixing piece 5b of the terminal 2 is formed in one side wall portion 4e.

  The partition 4 a is provided to extend in the front-rear direction Y as shown in FIGS. 1 and 23, and a plurality of fitting chambers 4 b are formed inside the housing 4. Particularly in the connector 1 of the present embodiment, the housing 4 has two partition walls 4a, and three fitting chambers 4b are formed. Therefore, it is possible to reduce the size of the connector 1 including the plurality of terminals 2 as a whole while preventing the occurrence of a short circuit between the adjacent terminals 2 by the partition walls 4a.

  As shown in FIG. 3, the fitting chamber 4 b includes a movable piece storage chamber 4 b 1 that stores the wound spring-like movable piece 6 and a contact portion storage chamber 4 b 2 that stores the contact contact portion 8. The movable piece storage chamber 4b1 is wider than the contact portion storage chamber 4b2, and is disposed above the contact portion storage chamber 4b2. The movable piece accommodating chamber 4b1 and the contact portion accommodating chamber 4b2 communicate with each other, so that one fitting chamber 4b accommodates one set of the wound spring-like movable piece 6 and the contact contact portion 8 that one terminal 2 has. Yes. In addition, the movable piece storage chamber 4b1 and the contact portion storage chamber 4b2 are provided so that the inner surface in the plane cross section is substantially rectangular (FIG. 23 shows a cross section taken along the line SC-SC in FIG. And only the movable piece storage chamber 4b1 and the partition wall 4a indicated by broken lines are shown, and the contact portion storage chamber 4b2 and the insertion hole 4d1 are omitted). Therefore, compared with the case where the inner surface in a plane cross section becomes substantially circular, for example, the fitting chamber 4b can be formed by efficiently using the occupied volume of the connector 1. The partition wall 4a is formed with a fixing groove 4h for inserting and fixing a fixing piece 5b of the terminal 2 described later.

  A fourth elastic piece 6d of the terminal 2 described later is exposed from the opening 4g of the fitting chamber 4b. The front end of the housing 4 is formed to be flush with the front end of the fourth elastic piece 6d exposed from the opening 4g (see FIGS. 19 and 23).

  As shown in FIGS. 2 and 6, the back wall portion 4 f has three window portions 4 f 1 communicating with the fitting chamber 4 b. The window 4f1 can release heat generated from the terminal 2 when energized. Further, the end face of the second elastic piece 6b of the wound spring-like movable piece 6 is exposed from the window portion 4f1. And the outer surface of the back wall part 4f is formed so that it may become flush | level with the rear end of the 2nd elastic piece 6b exposed from the window part 4f1 (refer FIG. 19, FIG. 23).

  As described above, the front end of the housing 4 is flush with the fourth elastic piece 6d, and the outer surface of the back wall portion 4f of the housing 4 is flush with the second elastic piece 6b. Is substantially the same as the length of the terminal 2 in the front-rear direction Y. Thereby, the connector 1 can be reduced in size as a whole while ensuring the minimum size required for the housing 4 to accommodate and protect the terminals 2 in the fitting chamber 4b.

(Terminal)
As shown in FIGS. 9 to 17, the terminal 2 has a base portion 5, a wound spring-like movable piece 6, a connecting piece 7, and a contact contact portion 8, which bend one metal piece. Is formed.

  As shown in FIGS. 10 and 16, the base 5 is inserted into a through hole (not shown) of the substrate P and soldered, and a fixed piece fixedly pressed into the fixing groove 4h. 5b and the base end part 5c are formed. The base end portion 5c is connected to the board connecting portion 5a and the fixed piece 5b, and an inclined piece portion 5c1 inclined in the front-rear direction Y is provided on the upper side. Further, the tip of the oblique piece 5c1 is connected to the wound spring-like movable piece 6.

  The coil spring-like movable piece 6 has a spiral spring shape as shown in FIGS. The plate surface of the metal plate forming the terminal 2 is formed along the height direction Z. The wound spring-like movable piece 6 includes a first elastic piece 6a extending rearward along the front-rear direction Y, a second elastic piece 6b extending in the width direction X connected to the first elastic piece 6a, A third elastic piece 6c that is connected to the second elastic piece 6b and extends forward along the front-rear direction Y, a third elastic piece 6c that is connected to the third elastic piece 6c and extends in the width direction X, and the second elastic piece 6b It has the 4th elastic piece 6d opposingly arranged, and the 5th elastic piece 6e connected to the 4th elastic piece 6d, and extended to the back side along the front-back direction Y. The fifth elastic piece 6e is disposed inside the spiral shape with respect to the first elastic piece 6a, and the end side of the fifth elastic piece 6e and the end side of the first elastic piece 6a overlap in the width direction X. . The second elastic piece 6b and the fourth elastic piece 6d have substantially the same length. Thus, the wound spring-like movable piece 6 is formed to be substantially rectangular in plan view. Therefore, as shown in FIG. 23, the wound spring-like movable piece can be compactly accommodated inside the movable piece accommodating chamber 4b1 of the fitting chamber 4b whose inner surface in the plane section is substantially rectangular.

  The coil spring-like movable piece 6 has a spring-side slit 6f extending along the winding direction as shown in FIGS. By doing so, the wound spring-like movable piece 6 can be divided into the thin divided movable pieces 6A and 6B, so that the wound spring-like movable piece 6 is soft and easily elastically deformed. The spring-side slit 6f is formed across the first elastic piece 6a to the fifth elastic piece 6e and the corners between the elastic pieces 6a to 6e. Therefore, since the wound spring-like movable piece 6 has longer divided movable pieces 6A and 6B, the wound spring-like movable piece 6 can be more easily elastically deformed.

  As shown in FIG. 19, the connecting piece 7 is a plate-like piece that is connected to the end of the fifth elastic piece 6 e of the wound spring-like movable piece 6 and extends downward. The connecting piece 7 can be arranged so as to be suspended directly below the wound spring-like movable piece 6 by being connected to a contact point contact part 8 described later. Thus, the wound spring-like movable piece 6 and the contact point contact portion 8 are arranged along the height direction Z. Therefore, for example, compared to the case where the wound spring-like movable piece 6 and the contact contact portion 8 are arranged adjacent to each other or arranged obliquely with respect to the height direction Z and shifted at different positions in the X direction or the Y direction. Thus, the area occupied by the wound spring-like movable piece 6 inside the fitting chamber 4b can be reduced. Thereby, the mounting area in the board | substrate P of the connector 1 provided with such a terminal 2 can be made small.

  As shown in FIG. 19, the contact contact portion 8 is connected to the lower end of the connecting piece 7 and has a substantially rectangular tube shape having a connection chamber 8 f into which the mating connector 3 is inserted. Further, the contact contact portion 8 includes a first contact wall portion 8a, a second contact wall portion 8b, a third contact wall portion 8c, a first contact wall portion 8a, and a second contact wall portion 8b. And a second connecting portion 8e for connecting the first contact wall portion 8a and the third contact wall portion 8c.

  As shown in FIG. 19, the first contact wall portion 8a is connected to the connecting piece 7, and has a first contact portion 8a1 and a second contact portion 8a2 that are in conductive contact with the pin-like terminal 3a. Each of the first contact portion 8a1 and the second contact portion 8a2 has an elongated convex shape along the height direction Z, and is disposed adjacently along the front-rear direction Y. An inclined portion 8a3 is provided at the lower end of the first contact wall portion 8a as a guide when the mating connector 3 is inserted into the connection chamber 8f.

  The second contact wall portion 8b has a third contact portion 8b1 that is disposed to face the first contact wall portion 8a and faces the first contact portion 8a1. The third contact portion 8b1 has a long and slender convex shape along the height direction Z like the first contact portion 8a1. At the lower end of the second contact wall portion 8b, an inclined portion 8b2 is provided which serves as a guide when the mating connector 3 is inserted into the connection chamber 8f.

  The third contact wall portion 8c includes a fourth contact portion 8c1 that is disposed to face the first contact wall portion 8a and faces the second contact portion 8a2. The fourth contact portion 8c1 also has a long and slender convex shape along the height direction Z, like the first contact portion 8a1. An inclined portion 8c2 is provided at the lower end of the third contact wall portion 8c to serve as a guide when the mating connector 3 is inserted into the connection chamber 8f.

  As shown in FIG. 10, the first connecting portion 8d connects the first contact wall portion 8a and the second contact wall portion 8b. A slit portion 8d1 is formed in the first connecting portion 8d, and an upper divided piece 8d2 and a lower divided piece 8d3 are provided. A guide piece 8d4 for inserting the mating connector 3 into the connection chamber 8f extends from the lower end of the lower divided piece 8d3.

  As shown in FIG. 9, the second connecting portion 8e connects the first contact wall portion 8a and the third contact wall portion 8c. The 2nd connection part 8e becomes symmetrical with the 1st connection part 8d, and has the slit part 8e1 similarly to the 2nd connection part 8e. Moreover, it has an upper divided piece 8e2 and a lower divided piece 8e3, and a guide piece 8e4 for inserting the mating connector 3 into the connection chamber 8f extends from the lower end of the lower divided piece 8e3.

[Description of connector assembly method]
As shown in FIG. 18, the terminal 2 is inserted into the fitting chamber 4 b from the opening 4 g provided on the front side of the housing 4. At that time, the fixing piece 5b is press-fitted inside the fixing groove 4h. In a conventional connector having a fixed housing and a movable housing, the movable housing is movable with respect to the fixed housing. Therefore, when the terminal is fixed to the movable housing, it is necessary to fix the terminal with a jig so that the movable housing does not move. It was. On the other hand, since the connector 1 of this embodiment does not have a movable housing, the operation of attaching the terminal 2 to the housing 4 can be easily completed without using a jig. In addition, since the contact contact portion 8 and the wound spring-like movable piece 6 of one terminal 2 are accommodated in one fitting chamber 4b, each is provided in a different housing or formed in a different space. Compared with the case where it connects, the connector 1 can be reduced in size as a whole.

[Explanation of usage]
The connector 1 is fixed by soldering in a state where the board connecting portion 5a is inserted into the through hole of the printed board P. Next, as shown in FIGS. 20 to 22, the pin-like terminal 3 a of the mating connector 3 is inserted into the fitting chamber 4 b from the insertion hole 4 d 1 provided in the lower wall portion 4 d of the housing 4. The pin-like terminal 3a is guided to the connection chamber 8f of the contact contact portion 8 by the inclined portions 8a3, 8b2 and 8c2 and the guide pieces 8d4 and 8e4. Then, while expanding the gap between the first contact portion 8a1 and the third contact portion 8b1 and the gap between the second contact portion 8a2 and the fourth contact portion 8c1, the connection chamber 8f It is inserted in the back side. Thus, the first contact portion 8a1 to the fourth contact portion 8c1 and the pin-like terminal 3a are brought into conductive contact, and the connection work of the pin-like terminal 3a is completed.

  The terminal 2 has a total of four contact portions, that is, the first contact portion 8a1 to the fourth contact portion 8c1, so that the current can be divided. Moreover, the 1st contact part 8a1-the 4th contact part 8c1 become elongate convex shape along the height direction Z as above-mentioned, and can be surface-contacted with the pin-shaped terminal 3a. Therefore, it is possible to make conductive contact with the pin-like terminal 3a in a wider area as compared with a contact portion having a sharp tip. Accordingly, the terminal 2 of the present embodiment can be adapted to a large current.

[Measures against vibration of substrates, etc.]
A case where the mating connector 3 is elastically displaced with respect to the connector 1 in a state where the connector 1 is engaged with the mating connector 3 will be described. In general, in order to softly and elastically deform a spring piece, it is necessary to increase the spring length of the spring piece. Therefore, in order to sufficiently elastically deform the spring piece, it is necessary to provide a long spring piece on the movable portion, and the terminal may be enlarged. Further, in order to sufficiently elastically deform the spring piece in a plurality of directions, it is necessary to provide a deformed portion that is elastically deformed in each direction. Therefore, in order to elastically deform the spring piece three-dimensionally, three deformed portions are provided, and the spring shape may be a complicated three-dimensional structure.

  On the other hand, in this embodiment, by making the movable part into the spiral spring-shaped movable piece 6 having a spiral shape, the spring length of the spiral spring-shaped movable piece 6 can be made compact while being lengthened. In addition, the wound spring-shaped movable piece 6 having such a shape can be softly and elastically deformed three-dimensionally in all directions of the front-rear direction Y, the width direction X, and the height direction Z. In this way, the wound spring movable piece 6 can be elastically deformed three-dimensionally with a simple structure and can absorb vibrations in all directions.

  The displacement load at which the coil spring-like movable piece 6 is displaced in the insertion / extraction direction of the pin-like terminal 3a is set smaller than the load at which the contact contact portion 8 is displaced in the insertion / extraction direction from the normal contact position with the pin-like terminal 3a. Yes. Therefore, even when the vibration along the height direction Z is applied while the contact contact portion 8 and the pin-shaped terminal 3a are in conductive contact, the contact contact portion 8 is positioned relative to the pin-shaped terminal 3a. The wound spring-like movable piece 6 can be elastically deformed in the height direction Z before being displaced. Therefore, when the wound spring-like movable piece 6 is elastically deformed and the contact contact portion 8 follows the pin-like terminal 3a without being displaced, the contact contact portion 8 is in sliding contact with the pin-like terminal 3a. It is possible to suppress the occurrence of peeling of the plating due to this. Thus, even if the mating connector 3 is elastically displaced not only in the width direction X and the front-rear direction Y but also in the height direction Z, the coil spring-like movable piece 6 is elastically deformed in the height direction Z. The conductive contact at the regular contact position between the portion 8 and the pin-like terminal 3a can be maintained.

  As described above, according to the connector 1 of this embodiment, by providing the wound spring-like movable piece 6, the contact contact portion 8 can be softly and elastically displaced three-dimensionally with a simple structure. Moreover, by accommodating such a wound spring-like movable piece 6 and the contact contact portion 8 in one fitting chamber 4b, the connector 1 can be reduced in size as a whole.

Variations:
In the said embodiment, the contact contact part 8 and the coiled spring-like movable piece 6 showed the example arrange | positioned along the height direction Z. On the other hand, it is good also as arrange | positioning so that the winding spring-shaped movable piece 6 may be wound around the outer side of the contact contact part 8. FIG. By doing so, since the terminal 2 can be made compact in the height direction Z, the connector 1 can be miniaturized as a whole.

  In the said embodiment, the coiled spring-shaped movable piece 6 has the 1st elastic piece 6a-the 5th elastic piece 6e, and showed the example which makes a substantially rectangular shape by planar view. On the other hand, the wound spring-like movable piece 6 may be substantially circular in plan view.

  In the said embodiment, the example which has the single wound spring shaped movable piece 6 in which the wound spring shaped movable piece 6 has the 1st elastic piece 6a-the 5th elastic piece 6e was shown. On the other hand, it is good also as the wound spring-shaped movable piece 6 wound by multiple. By carrying out like this, it can be set as the coiled spring-shaped movable piece 6 whose spring length is longer and can be softly elastically deformed.

  In the said embodiment, the example in which the coiled spring-shaped movable piece 6 was formed so that the plate | board surface of the metal plate which forms the terminal 2 followed the height direction Z was shown. On the other hand, the plate surface of the metal plate may be formed along the XY plane. By carrying out like this, it can be set as the coiled spring-shaped movable piece 6 which is easy to elastically deform in the height direction Z.

  In the said embodiment, the example which the coiled spring-shaped movable piece 6 consists of a spiral spring shape was shown. On the other hand, it is good also as what consists of a helical spring shape, for example. By doing so, the spring length can be increased without increasing the size in the width direction X and the front-rear direction Y. Moreover, it can be set as the coiled spring-shaped movable piece 6 which is more easily elastically deformed in the height direction Z by making it a helical spring shape.
