Since the connector includes a plurality of housings, a fixed housing and a movable housing, the connector becomes large as a whole. Further, in order for the movable portion to sufficiently absorb the vibration of the substrate or the like, it is necessary to make the spring piece of the movable portion soft and elastically deformable. In this case, it is necessary to lengthen the spring length, but the longer the spring length, the larger the terminal as a whole may be.

The present invention has been made against the above background, and an object of the present invention is to provide a terminal capable of sufficiently absorbing vibration of a substrate or the like and maintaining conductive contact with an object to be connected, and a small connector provided with the terminal. Is.

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 that is arranged in the fitting chamber and is in conductive contact with the pin-shaped connection object inserted in the fitting chamber. , It is a winding spring shape that is arranged in the fitting chamber and follows the axial direction of the pin-shaped connection object, and elastically supports the contact contact part in the fitting chamber so that it can be displaced in three dimensions. Provided is a connector including a terminal having a movable piece.

Since the terminal has a wound spring-shaped movable piece, the spring piece can be made compact as a whole while increasing the spring length. Therefore, the spring-shaped movable piece can be softly and elastically deformed. In addition, one housing has multiple housings by having a fitting chamber that accommodates both the spring-loaded movable piece and the contact contact, compared to a connector in which the terminals are fixed to the multiple housings. It can be a small connector.

It can be assumed that the spring-shaped movable piece of the present invention forms a polygonal shape in the winding direction.

By doing so, it is possible to obtain terminals that can be efficiently and easily fitted in the fitting chamber of the housing. Therefore, a more compact connector can be obtained.

The wound spring-shaped movable piece of the present invention may have a plurality of split movable pieces branched by a slit extending along the winding direction.

By doing so, the spring-shaped movable piece can be composed of a plurality of thin split movable pieces, so that the spring-shaped movable piece can be softly and elastically deformed as a whole.

It is possible that the slit of the present invention is provided over a plurality of corners of the spring-shaped movable piece forming the polygonal shape.

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

It is assumed that the wound spring-shaped movable piece of the present invention and the contact contact portion are arranged inside the fitting chamber along the insertion / removal direction of the connection object.

By doing so, the terminals can be miniaturized in the intersecting direction with respect to the insertion / removal direction of the object to be connected. As a result, the occupied area of the entire connector can be reduced.

The terminal of the present invention has a substrate connecting portion arranged in the housing and a base portion extending from the substrate connecting portion to the fitting chamber of the housing, and the wound spring-shaped movable piece has one end connected to the base portion. It can be assumed that the side is located at the upper part of the fitting chamber, and the contact contact portion is connected to the other end side of the spring-shaped movable piece and is located at the lower part of the fitting chamber.

By making the terminals in this shape, a board connection part that is conductively connected to the board is secured, and the wound spring-shaped movable piece and the contact contact part are arranged vertically inside the fitting chamber, which is the occupied area on the board. Terminals with a small area can be easily manufactured from a single metal plate.

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

By doing so, even when the object to be connected is elastically displaced with respect to the housing along the insertion / extraction direction, the contact contact portion is shaped like a spring before being displaced from the regular contact position with the object to be connected. The movable piece elastically deforms in the insertion / extraction direction. Therefore, the contact contact portion can follow the object to be connected 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 spring-shaped movable piece may have a spring-shaped movable portion having a polygonal shape along the inner surface of the fitting chamber.

By forming 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. Further, since the wound spring-shaped movable piece can be compactly accommodated in the fitting chamber by forming the shape along the inner surface of the fitting chamber, the entire connector can be further miniaturized.

A plurality of terminals of the present invention are provided, the housing has a plurality of fitting chambers, and a contact contact portion and a spring-shaped movable piece of one terminal are arranged in each fitting chamber. Can be assumed to be.

By doing so, it is possible to secure a space in which each spring-shaped movable piece is sufficiently elastically deformed while surely preventing a short circuit with other terminals. Further, it is possible to make a small connector while having a plurality of terminals.

According to the present invention, a terminal having a spring-shaped movable piece that is soft and elastically deformed can maintain conductive contact between the contact contact portion and the object to be connected by absorbing vibration of a substrate or the like, and can be made into a small connector. be able to.

The connector 1 is a conductive connection between the board circuit of the board P on which the connector 1 is mounted and the pin-shaped terminal 3a of the mating connector 3 which is the connection target of the connector 1. As shown in FIGS. 1 to 8, such a connector 1 has a housing 4 and a plurality of terminals 2 held in 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 has 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.

As shown in FIG. 6, the lower wall portion 4d is formed with an insertion hole 4d1 for the mating connector 3. The lower wall portion 4d faces the substrate P with the connector 1 mounted on the substrate P.

The upper wall portion 4c is arranged so as to cover the terminal 2 housed in the fitting chamber 4b as shown in FIGS. 3 and 4. When the pin-shaped 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-shaped terminal 3a. The spring-shaped movable piece 6 of the terminal 2 is also elastically deformed upward so that it can be lifted. However, when the spring-shaped movable piece 6 comes into contact with the upper wall portion 4c, the elastic deformation is stopped, and the pin-shaped terminal 3a can be inserted into the connection chamber 8f of the contact contact portion 8.

As shown in FIGS. 7 and 8, the side wall portions 4e connect the upper wall portion 4c and the lower wall portion 4d, and are provided one on each end side in the width direction X of the housing 4.

In the connector 1 of the present embodiment, in particular, the housing 4 has two partition walls 4a, and three fitting chambers 4b are formed. Therefore, the connector 1 provided with the plurality of terminals 2 can be miniaturized as a whole while preventing the occurrence of a short circuit between the adjacent terminals 2 by the partition wall 4a.

As shown in FIG. 3, the fitting chamber 4b has a movable piece accommodating chamber 4b1 accommodating the spring-shaped movable piece 6 and a contact portion accommodating chamber 4b2 accommodating the contact contact portion 8. The movable piece storage chamber 4b1 is wider than the contact portion storage chamber 4b2 and is arranged above the contact portion storage chamber 4b2. By communicating the movable piece accommodating chamber 4b1 and the contact portion accommodating chamber 4b2 with each other, one fitting chamber 4b accommodates a set of a spring-shaped movable piece 6 and a contact contact portion 8 possessed by one terminal 2. There is. Further, the movable piece accommodating chamber 4b1 and the contact portion accommodating chamber 4b2 are each provided so that the inner surface in the plan cross section is substantially rectangular (in FIG. 23, the cross section shown by the arrow SC-SC line in FIG. 21 is shown, but the terminal 2 Only the movable piece accommodating chamber 4b1 and the partition wall 4a shown by the broken lines are described, and the contact portion accommodating chamber 4b2 and the insertion hole 4d1 are omitted). Therefore, the fitting chamber 4b can be formed by efficiently utilizing the occupied volume of the connector 1 as compared with the case where the inner surface in the flat cross section is, for example, substantially circular. The partition wall 4a is formed with a fixing groove 4h for inserting and fixing the fixing piece 5b of the terminal 2 described later.

The fourth elastic piece 6d of the terminal 2, which will be described later, is exposed from the opening 4g of the fitting chamber 4b. The front end of the housing 4 is formed so as 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 4f has three window portions 4f1 communicating with the fitting chamber 4b. The window portion 4f1 can release heat generated from the terminal 2 when energized. Further, the end face of the second elastic piece 6b of the spring-shaped movable piece 6 is exposed from the window portion 4f1. The outer surface of the back wall portion 4f is formed so as to be flush with the rear end of the second elastic piece 6b exposed from the window portion 4f1 (see FIGS. 19 and 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. The length of the terminal 2 is substantially the same as the length of the terminal 2 in the front-rear direction Y. As a result, the connector 1 can be miniaturized as a whole while ensuring the minimum necessary size for the housing 4 to accommodate and protect the terminal 2 in the fitting chamber 4b.

[Terminal]
As shown in FIGS. 9 to 17, the terminal 2 has a base portion 5, a spring-loaded movable piece 6, a connecting piece 7, and a contact contact portion 8, which are obtained by bending one metal piece. Is formed.

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

The spiral spring-shaped movable piece 6 has a spiral spring shape as shown in FIGS. 9 and 10. Further, the plate surface of the metal plate forming the terminal 2 is formed along the height direction Z. The wound spring-shaped movable piece 6 includes a first elastic piece 6a extending rearward along the front-rear direction Y, a second elastic piece 6b connected to the first elastic piece 6a and extending in the width direction X, and the like. A third elastic piece 6c connected to the second elastic piece 6b and extending forward along the front-rear direction Y, and a second elastic piece 6b connected to the third elastic piece 6c and extending in the width direction X. It has a fourth elastic piece 6d arranged so as to face each other, and a fifth elastic piece 6e that is connected to the fourth elastic piece 6d and extends rearward along the front-rear direction Y. The fifth elastic piece 6e is arranged inside the spiral shape of the first elastic piece 6a, and the terminal side of the fifth elastic piece 6e and the terminal side of the first elastic piece 6a overlap in the width direction X. .. Further, the second elastic piece 6b and the fourth elastic piece 6d have substantially the same length. In this way, the wound spring-shaped movable piece 6 is formed so as to be substantially rectangular in a plan view. Therefore, as shown in FIG. 23, the spring-shaped movable piece can be compactly stored inside the movable piece storage chamber 4b1 of the fitting chamber 4b whose inner surface is substantially rectangular in the plan cross section.

The wound spring-shaped movable piece 6 has a spring-side slit 6f that extends along the winding direction as shown in FIGS. 9 and 10. By doing so, the spring-shaped movable piece 6 can be divided into thin split movable pieces 6A and 6B, so that the spring-shaped movable piece 6 is soft and easily elastically deformed. Further, the spring-side slit 6f is formed over the corners between the first elastic pieces 6a to the fifth elastic pieces 6e and the elastic pieces 6a to 6e. Therefore, since the spring-shaped movable piece 6 has the longer split movable pieces 6A and 6B, the spring-shaped movable piece 6 can be more easily elastically deformed.

As shown in FIG. 19, the connecting piece 7 is a plate-shaped piece that is connected to the end of the fifth elastic piece 6e of the spring-shaped movable piece 6 and extends downward. By connecting the connecting piece 7 with the contact contact portion 8 described later, the contact contact portion 8 can be arranged so as to be suspended directly under the spring-shaped movable piece 6. In this way, the spring-shaped movable piece 6 and the contact contact portion 8 are arranged along the height direction Z. Therefore, as compared with the case where the wound spring-shaped movable piece 6 and the contact contact portion 8 are adjacent to each other or arranged at different positions in the X direction or the Y direction so as to be arranged diagonally with respect to the height direction Z, for example. As a result, the area occupied by the spring-shaped movable piece 6 inside the fitting chamber 4b can be reduced. As a result, the mounting area of the connector 1 provided with the terminal 2 on the substrate P can be reduced.

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 square tubular shape having a connection chamber 8f 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. It has a first connecting portion 8d for connecting the above, 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 has a first contact portion 8a1 and a second contact portion 8a2 that are connected to the connecting piece 7 and are in conductive contact with the pin-shaped terminal 3a. The first contact portion 8a1 and the second contact portion 8a2 each have an elongated convex shape along the height direction Z, and are arranged adjacent to each other along the front-rear direction Y. At the lower end of the first contact wall portion 8a, an inclined portion 8a3 that serves as a guide when the mating connector 3 is inserted into the connection chamber 8f is provided.

The second contact wall portion 8b is arranged to face the first contact wall portion 8a and has a third contact portion 8b1 facing the first contact portion 8a1. The third contact portion 8b1 has an elongated 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 that serves as a guide when the mating connector 3 is inserted into the connection chamber 8f is provided.

The third contact wall portion 8c is arranged to face the first contact wall portion 8a and has a fourth contact portion 8c1 facing the second contact portion 8a2. The fourth contact portion 8c1 also has an elongated convex shape along the height direction Z like the first contact portion 8a1. At the lower end of the third contact wall portion 8c, an inclined portion 8c2 that serves as a guide when the mating connector 3 is inserted into the connection chamber 8f is provided.

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 split piece 8d2 and a lower split 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 split 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 second connecting portion 8e has a symmetrical shape with the first connecting portion 8d, and has a slit portion 8e1 like the second connecting portion 8e. Further, it has an upper split piece 8e2 and a lower split 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 split piece 8e3.

[Explanation of connector assembly method]
As shown in FIG. 18, the terminal 2 is inserted into the fitting chamber 4b through the opening 4g provided on the front side of the housing 4. At that time, the fixing piece 5b is press-fitted into the fixing groove 4h. In a conventional connector having a fixed housing and a movable housing, since the movable housing is movable with respect to the fixed housing, when fixing the terminal to the movable housing, it is necessary to fix the movable housing with a jig so that the movable housing does not move. It was. On the other hand, since the connector 1 of the present embodiment does not have a movable housing, the work of attaching the terminal 2 to the housing 4 can be easily completed without using a jig. Further, since the contact contact portion 8 and the spring-shaped movable piece 6 of one terminal 2 are housed inside one fitting chamber 4b, they are provided in different housings or formed in different spaces. The connector 1 can be miniaturized as a whole as compared with the case where the connector 1 is used.

[Explanation of usage]
The connector 1 is soldered and fixed with the board connection portion 5a inserted into the through hole of the printed circuit board P. Next, as shown in FIGS. 20 to 22, the pin-shaped terminal 3a of the mating connector 3 is inserted into the fitting chamber 4b through the insertion hole 4d1 provided in the lower wall portion 4d of the housing 4. The pin-shaped 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 arranged to face each other, the connection chamber 8f It is inserted in the back side. In this way, the first contact portions 8a1 to the fourth contact portions 8c1 and the pin-shaped terminal 3a are in conductive contact with each other, and the connection work of the pin-shaped 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 diverted. Further, as described above, the first contact portions 8a1 to the fourth contact portions 8c1 have an elongated convex shape along the height direction Z, and can be in surface contact with the pin-shaped terminal 3a. Therefore, it is possible to make conductive contact with the pin-shaped terminal 3a in a wider area as compared with the contact portion having a sharp tip. As a result, the terminal 2 of the present embodiment can handle a large current.

[How to deal with vibration of substrates, etc.]
A case where the mating connector 3 is elastically displaced with respect to the connector 1 while the connector 1 is fitted with the mating connector 3 will be described. Generally, in order to softly and elastically deform a spring piece, it is necessary to lengthen 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 in the movable portion, and the terminal may become large. Further, in order to sufficiently elastically deform the spring piece in a plurality of directions, it is necessary to provide a deformed portion that elastically deforms in each direction. Therefore, in order to elastically deform the spring piece three-dimensionally, three deformed portions are provided, and the spring shape may have a complicated three-dimensional structure.

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

The displacement load in which the spring-shaped movable piece 6 is displaced in the insertion / removal direction of the pin-shaped terminal 3a is set smaller than the load in which the contact contact portion 8 is displaced from the regular contact position with the pin-shaped terminal 3a in the insertion / removal direction. There is. Therefore, even when 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 with respect to the pin-shaped terminal 3a. The wound spring-shaped movable piece 6 can be elastically deformed in the height direction Z before being displaced. Therefore, the spring-shaped movable piece 6 is elastically deformed and the contact contact portion 8 follows the pin-shaped terminal 3a without being displaced, so that the contact contact portion 8 makes sliding contact with the pin-shaped terminal 3a. It is possible to suppress the occurrence of plating peeling and the like due to this. In this way, even when 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 wound spring-shaped movable piece 6 elastically deforms in the height direction Z to make contact contact. It is possible to maintain conductive contact at the regular contact position between the portion 8 and the pin-shaped terminal 3a.

As described above, according to the connector 1 of the present embodiment, by providing the winding spring-shaped movable piece 6, the contact contact portion 8 can be three-dimensionally softly and elastically displaced with a simple structure. Further, by accommodating the spring-shaped movable piece 6 and the contact contact portion 8 in one fitting chamber 4b, the connector 1 can be miniaturized as a whole.

Modification example:
In the above embodiment, an example is shown in which the contact contact portion 8 and the spring-shaped movable piece 6 are arranged along the height direction Z. On the other hand, the spring-shaped movable piece 6 may be arranged so as to be wound on the outside of the contact contact portion 8. By doing so, the terminal 2 can be made compact in the height direction Z, so that the connector 1 can be miniaturized as a whole.

In the above embodiment, an example is shown in which the wound spring-shaped movable piece 6 has the first elastic piece 6a to the fifth elastic piece 6e and has a substantially rectangular shape in a plan view. On the other hand, the wound spring-shaped movable piece 6 may have a substantially circular shape in a plan view.

In the above embodiment, an example is shown in which the spring-shaped movable piece 6 has a single spring-shaped movable piece 6 having the first elastic piece 6a to the fifth elastic piece 6e. On the other hand, a spring-shaped movable piece 6 that is wound multiple times may be used. By doing so, it is possible to obtain a wound spring-like movable piece 6 having a longer spring length and being soft and elastically deformable.

In the above embodiment, an example is shown in which the wound spring-shaped movable piece 6 is formed so that the plate surface of the metal plate forming the terminal 2 is formed along the height direction Z. On the other hand, the plate surface of the metal plate may be formed along the XY plane. By doing so, the spring-shaped movable piece 6 that is more easily elastically deformed in the height direction Z can be obtained.

In the above embodiment, an example in which the spiral spring-shaped movable piece 6 has a spiral spring shape is shown. On the other hand, for example, it may have a spiral spring shape. By doing so, the spring length can be made longer without increasing the size in the width direction X and the front-rear direction Y. Further, by forming the shape of the spiral spring, the movable piece 6 can be formed into a spring-like movable piece that is more easily elastically deformed in the height direction Z.
