Description

  The present invention relates to a connector that is interposed between two connection objects and electrically connects the connection objects.

  Conventionally, a connector including a plurality of contacts and first and second housings for holding the contacts is known (see Patent Document 1 below).

  As shown in FIGS. 3 and 4, the mating connector 900 includes a mating housing 910 and a plurality of mating contacts 920.

  The mating housing 910 has a box shape, and an upper portion thereof is open. The mating housing 910 is integrally formed of an insulating resin. The mating housing 910 has a front part 911, a back part 912, a bottom part 913, and side parts 914 and 914.

  The distance between the inner surface of the front portion 911 and the inner surface of the back surface portion 912 is such that the movable housing 30 is slightly movable in the Y direction between them. A recess 912 a is further formed on the inner surface of the back surface portion 912. Further, grooves 912b are formed on the inner surface of the back surface portion 912 at equal intervals along the X direction. The groove 912b extends in the fitting / removing direction F. Further, an invitation surface 912c is formed on the upper end portion of the back surface portion 912.

  A concave portion 911a, a groove (not shown), and an invitation surface (not shown) are formed on the inner surface of the front portion 911 similarly to the inner surface of the rear portion 912.

  As shown in FIGS. 4 and 7, the counterpart contact 920 has a contact portion 921 and a plurality of connection portions 922. The contact portion 921 and the connection portion 922 are integrally formed. The contact portion 921 has a plate shape. Each of the plurality of connection portions 922 has a pin shape, and is connected to the contact portion 921 at equal intervals.

  The mating contact 920 is press-fitted into the slit 913 b of the bottom surface portion 913 of the mating housing 910.

  Next, the operation of the connector 100 will be described.

  The connector 100 is mounted on a printed board (not shown), and the connecting portion 22 of the fixed contact 20 is inserted into a through hole of the printed board and soldered. The mating connector 900 is mounted on another printed circuit board (not shown), and the connection portion 922 of the mating contact 920 is inserted into the through hole of the printed circuit board and soldered.

  As shown in FIG. 5, the connector 100 and the mating connector 900 face each other and are fitted together.

  At this time, even if the center of the connector 100 and the center of the mating connector 900 are displaced in the X direction, the movable housing 30 slides relative to the fixed housing 10 as shown in FIG. And the mating housing 910 are fitted. The movable housing 30 is not inclined with respect to the fitting / removing direction F. Further, there are gaps between the front portion 31 of the movable housing 30 and the front portion 911 of the counterpart housing 910 and between the back portion 32 of the movable housing 30 and the back portion 912 of the counterpart housing 910, respectively. Since the side housing 30 can move in the Y direction, the deviation in the Y direction between the connector 100 and the mating connector 900 is absorbed.

  When the movable housing 30 slides to the right with respect to the fixed housing 10 as shown in FIG. 8, the movable contact 40 simply rotates counterclockwise around the connecting portion 45 as shown in FIG. Yes, almost no elastic deformation. Therefore, compared with the case where the center of the connector 100 and the center of the counterpart connector 900 are not shifted in the X direction, the contact portion 21 of the fixed contact 20 or the contact portion 921 of the counterpart contact 920 and the movable contact 40 The contact force generated between them hardly changes.

  According to this embodiment in which the movable contact 40 rotates, when the connector 100 is fitted to the mating connector 900, the contact portion 21 of the fixed contact 20, the contact portion 921 of the mating contact 920, the movable contact 40, The contact force generated during the change hardly changes.

  Therefore, even if the center of the connector 100 and the center of the mating connector 900 are shifted, the connector 100 can be fitted to the mating connector 900 with a small force. Further, when the center of the connector 100 and the center of the mating connector 900 are shifted in the X direction, the deformation amount of the movable contact 40 when the connector 100 and the mating connector 900 are fitted, and the center of the connector 100 When the connector 100 and the mating connector 900 are fitted together when the center of the mating connector 900 is not shifted in the X direction, the deformation amount of the movable contact 40 is almost the same. Plastic deformation can be prevented and contact stability can be maintained. Further, the connector 100 can be detached from the mating connector 900 with a small force.

  Furthermore, in order to reduce the insertion force and removal force of the connector, it is not necessary to make the contact elongated in order to increase the displacement amount of the displacement portion of the contact as in the conventional connector, so that the movable housing 30 can be made small. The connector 100 can be easily downsized.

  Further, instead of downsizing the movable housing 30, the connector 100 can be used as a high current capacity connector by thickening the movable contact 40.

  Further, since the protruding portion 44 c of the movable contact 40 is inserted into the hole 33 c of the movable housing 30, it is possible to suppress the second contact portion 44 of the movable contact 40 from shaking greatly in the contact accommodating chambers 38 and 39. .

  In the above-described embodiment, the connecting portion 45 of the movable contact 40 is rotatably supported by the fixed housing 10 and the movable housing 30, but the connecting portion 45 of the movable contact 40 is not necessarily fixed. And the movable housing 30 may not be supported. For example, the connecting portion 45 may be supported only by the movable housing 30.

  In the above-described embodiment, the first contact portion 43 and the second contact portion 44 of the movable contact 40 are shaped to sandwich the fixed contact 20 and the counterpart contact 920, respectively. The shape of the two contact portion 44 is not limited to the shape that sandwiches the stationary contact 20 or the counterpart contact 920.

  In the above-described embodiment, the shake suppressing means is configured by the protruding portion 44c of the movable contact 40 and the hole 33c of the movable housing 30 into which the protruding portion 44c is inserted. However, the configuration of the shake suppressing means is limited to this. Not what you want.

  In the above-described embodiment, the convex portions 11d, 12d, 31d, and 32d are formed on the fixed housing 10 and the movable housing 30, respectively. However, the convex portions 11d, 12d, 31d, and 32d are formed on the connecting portion 45 of the movable contact 40. It may be formed. In this case, only the step surfaces 11a, 12a, 31a, and 32a are formed in the fixed housing 10 and the movable housing 30.

  Moreover, although the front-end | tip part of convex part 11d, 12d, 31d, 32d is circular arc shape, a square-shaped protrusion may be sufficient and a shape is not restricted to circular arc shape.
