Japanese Patent No. 3635398

  Since the first and second switch pieces disclosed in Patent Document 1 have the same extension direction and the same size as the contacts provided in the electrical connector, the first and second spring portions have the same size. The length is limited. For this reason, in order to ensure the elasticity required for stable and reliable switch operation, the plate | board thickness and plate | board width of a spring part must be made comparatively large. However, this leads to an increase in occupied space, and as a result, it is disadvantageous for reducing the size and height of the electrical connector. Further, the switch spring is hard and requires a large insertion force when the mating connector is inserted, which may result in poor operability.

  Therefore, an object of the present invention is to provide an electrical connector that not only performs a highly reliable switch operation but also has a small occupied space and excellent operability.

(5) may have a second terminal portion (14) extending from the second holding portion (12) and connected to the conductive pattern on the substrate. In this case, the first terminal portion (13) and the second terminal portion (14) may be a surface mounting type or an implantation type on a mounting object of the connector.

  Furthermore, a detection circuit that detects the mating of the mating connector by electrically detecting opening and closing of the detection switch may be further included.

  The electrical connector according to the present invention not only performs highly reliable switch operation, but also occupies a small space and is excellent in operability.

  Hereinafter, an embodiment of an electrical connector according to the present invention will be described with reference to the drawings.

  Referring to FIG. 4 and FIGS. 5A to 5D, this electrical connector is electrically connected to the resinous housing 2 and the contacts 102 of the mating connector 100 shown in FIG. A plurality of contacts 1 that can be connected to each other, and a detection switch that is held in the housing 2 and detects fitting with the mating connector 100.

  Further referring to FIGS. 7, 8, 9 (a) and 9 (b) and FIGS. 10 (a) and 10 (b), the detection switch of this electrical connector includes the first switch piece 4, 2 switch pieces 5.

  The first switch piece 4 includes a first holding portion 9 that is held by being press-fitted into the housing 2, a first spring portion 6 that extends from the first holding portion 9, and a first spring portion 6. A first contact portion 8 provided at the distal end; and a pressed portion 7 formed to extend so as to confront the mating connector 100 when the mating connector 100 is inserted from the first contact portion 8. Yes.

  The second switch piece 5 includes a second holding portion 12 held by being press-fitted into the housing, and a second spring portion 11 extending from the second holding portion 12 in a direction approaching the first contact portion 8. And a second contact portion 10 provided at the tip of the second spring portion 11.

  When the mating connector 100 is fitted, the pressed portion 7 is pressed by the tip portion 101 of the mating connector 100, and the first contact portion 8 is displaced along with the elastic deformation of the first spring portion 6. Furthermore, the second contact portion 10 is displaced together with the elastic deformation of the second spring portion 11 by pressing the second contact portion 10 while the first contact portion 8 is in sliding contact with the second contact portion 10. . That is, the first contact portion 8 and the second contact portion 10 are in sliding contact, and the connected state is maintained thereafter.

  Accordingly, the first and second switch pieces 4 and 5 operate as detection switches that are opened when the mating connector 100 is not mated and closed when the mating connector 100 is mated. The first and second switch pieces 4 and 5 are connected to a detection circuit 50 (FIGS. 12A and 12B) that detects the presence or absence of fitting based on the opening and closing of the detection switch, and the mating connector It is detected whether 100 is fitted.

  Particularly in the present invention, the first spring portion 6 and the second spring portion 11 extend in the connector width direction W perpendicular to the fitting direction D of the mating connector 100.

  When the mating connector 100 is fitted, the first spring portion 6 is elastically deformed in the fitting direction D, whereby the first contact portion 8 is displaced in the fitting direction D, and the second contact portion 10 is The first contact portion 8 is pressed in the connector height direction H perpendicular to the fitting direction D and the width direction W. At this time, the second spring portion 11 is elastically deformed in the height direction H, and the first contact portion 8 and the second contact portion 10 are displaced while sliding. Even after the sliding contact, the connection state between the first contact portion 8 and the second contact portion 10 is maintained.

  Compared to the electrical connector of Patent Document 1 in which the first spring portion 6 and the second spring portion 11 extend in the connector width direction W, so that the length of the spring portion is limited to the same extent as other constants. The lengths of the first and second spring portions are long, so that the elasticity necessary for a stable and reliable switch operation can be ensured without increasing the plate thickness and plate width of the spring portions. At the same time, the sliding allowance (effective sliding contact length) between the first and second contact portions can be sufficiently secured. Furthermore, since it is not necessary to increase the plate thickness and the plate width of the spring portion, the occupied space is not increased, which is advantageous for reducing the size and height of the electrical connector. Furthermore, the spring of the switch is not hard, so that a large insertion force is not required when the mating connector is inserted, and the operability is excellent.

  The first spring portion 6 is curved in a substantially U shape. As a result, a longer spring length is ensured as compared with the case where the first spring portion 6 is simply straight along the connector width direction W. Further, the second spring portion 11 is bent. Accordingly, a longer spring length is ensured as compared with the case where the second spring portion 11 is simply straight along the connector width direction W.

  The first contact portion 8 has a curved surface. On the other hand, the 2nd contact part 10 is provided with the inclined guide part 10a and the plane part 10b following it. And when the 1st contact part 8 and the 2nd contact part 10 are slidably contacted, the 1st contact part 8 slidably contacts on the guide part 10a and the plane part 10b following this.

  The electrical connector further includes a metal shell 3 that covers the housing 2.

  The first switch piece 4 has a first terminal portion 13 that extends from the first holding portion 9 and is connected to a conductive pattern on the substrate. Similarly, the 2nd switch piece 5 has the 2nd terminal part 14 extended from the 2nd holding | maintenance part 12 and connected with the conductive pattern on a board | substrate. In this embodiment, the 1st terminal part 13 and the 2nd terminal part 14 are the surface mounting types to the electric circuit board etc. which are not shown in figure as a mounting object of this electrical connector. However, in the present invention, the terminal portion of the switch piece may be an implanted type that has a lead shape that can be inserted into a through hole formed in an electric circuit board or the like that is a mounting target.

  Next, with reference to FIGS. 11A to 11C, the operation of the electrical connector, that is, the flow until the detection switch is activated and the mating of the mating connector 100 is detected will be described.

  Now, the mating connector 100 is not fitted into this electrical connector, and the first contact portion 8 of the first switch piece 4 and the second contact portion 10 of the second switch piece 5 are 11 (a). Here, when the mating connector 100 is not mated, the first and second switch pieces 4 and 5 are connected to a detection circuit 50 that detects the presence or absence of mating based on opening and closing of the detection switch. Is in the state shown in FIG. 12A, and the detection circuit 50 detects that the mating connector 100 is not fitted.

  Insertion of the tip 101 (FIG. 6) of the mating connector 100 into the electrical connector is started, and the mating connector is placed on the pressed portion 7 of the first switch piece 4 as shown in FIG. 11 (b). When the tip of 100 comes into contact and the pressed portion 7 is pressed in the fitting direction D (rightward in the figure) by the mating connector 100 being fitted, the first contact portion 8 becomes the second contact portion 10. It abuts on the guide 10a. As the first contact portion 8 moves to the right in the drawing, the second contact portion 10 starts to be pushed down in the connector height direction H (downward in the drawing).

  When the mating connector 100 continues to be further inserted in the fitting direction D (rightward in the figure), the first contact portion 8 is in sliding contact with the flat surface portion 10b of the second contact portion 10. Then, as shown in FIG. 11C, when the mating connector 100 is inserted to the specified position and the fitting is completed, the first contact portion 8 and the flat portion 10b of the second contact portion 10 are securely connected. And a sufficient contact allowance (effective contact length) is secured. At this time, the first contact portion 8 receives an elastic force from the second contact portion 10.

  As described above, by fitting the mating connector 100, the first switch piece 4 and the second switch piece 5 of the electrical connector are connected. When the mating connector 100 is fitted, it is in the state shown in FIG. 12B, and the detection circuit 50 detects that the mating connector 100 is fitted.
