Description

  The present invention relates to a connector having a structure that slides to a pressing position and presses a female contact against an inserted male contact.

  For example, there is known a connector having the above-described structure that is planned to be mounted in a place with a lot of vibration such as in a car.

  For example, Patent Document 1 discloses a connector having a structure in which a curved portion of a female contact is pressed against a male contact that is a counterpart contact by inserting an insertion member into the female contact accommodated in the housing.

JP 2013-93318 A

  Patent Document 1 listed above describes that the connector having the structure disclosed therein can be downsized while absorbing vibration.

  However, in the case of the connector disclosed in Patent Document 1, when the insertion member vibrates due to external vibration, the contact pressure of the female contact with respect to the male contact changes, causing minute sliding wear and lowering reliability. There is a risk.

  In view of the above circumstances, an object of the present invention is to provide a connector in which a change in contact pressure of a female contact with respect to a male contact is suppressed even when subjected to vibration from the outside.

The connector of the present invention that achieves the above object provides:
A contact subassembly having a female contact and a first housing supporting the female contact;
A pressing member provided for each pair of one female contact and one male contact that presses the female contact against the male contact inserted into the female contact in a state of sliding to the pressing position, and the pressing member A second housing that supports the slide member, and a slide member that is slidable between a pressing position and a release position in which the male contact is released from the pressing of the female contact; A frame for guiding the slide of the slide member;
The slide member has a relative vibration suppressing structure that slides to a pressing position and suppresses relative vibration between the slide member and the contact subassembly.

  When the slide member and the contact subassembly are relatively vibrated when subjected to external vibration, the contact pressure changes, but even if they vibrate together, the contact pressure does not change.

  The present invention focuses on this point. That is, according to the present invention, since the above-mentioned pressing member has a relative vibration suppressing structure, a change in contact pressure of the female contact with respect to the male contact can be suppressed. As a result, fine sliding wear is suppressed, and a highly reliable connector is realized.

  Here, in the connector of the present invention, the pressing member is a spring member having a shape in which the metal member is folded in half, and a part of the contact subassembly is elastically held by sliding to the pressing position. In the state where the slide member is slid to the pressing position, the female contact is pressed against the male contact inserted into the female contact, and a part of the contact subassembly is clamped. A member that suppresses relative vibration between the contact subassembly and the slide member is preferable.

  Specifically, the slide member may include a pressing member having a simple structure in which a part of the contact subassembly is sandwiched by a spring member obtained by bending a metal member. The slide member provided with the pressing member having this structure can have an action of pressing the female contact against the male contact and an action of suppressing relative vibration.

  According to the present invention described above, a connector in which a change in contact pressure of the female contact with respect to the male contact is suppressed even when subjected to vibration from the outside is realized.

  The connector 100 is mounted on the circuit board 200. The circuit board 200 is formed with a through hole 201 through which the male contact 51 passes. Corresponding to the connector 100 having five female contacts 21 (see FIG. 1), five male contacts 51 are provided on a circuit board (not shown) different from the circuit board 200 shown here. . Then, these five male contacts 51 pass through the through hole 201 of the circuit board 200 and are inserted into each of the five female contacts 21 of the connector 100.

  4 to 6 are cross-sectional views of the connector of the present embodiment, taken along arrow AA shown in FIG.

  Here, FIG. 4 is a sectional view of a single connector 100. In FIG. 4, the slide member 30 is in the release position as in FIG.

  FIG. 5 is a cross-sectional view of a state where the connector 100 is mounted on the circuit board 200 and the male contact 51 is inserted into the connector 100. Also in FIG. 5, the slide member 30 is in the release position.

  6 is a cross-sectional view of the state in which the slide member 30 has been slid to the pressing position after the state shown in FIG.

  As described above, the contact subassembly 20 includes the first housing 22 and the female contact 21 supported by the first housing 22. In the present embodiment, the female contact 21 is press-fitted into the first housing 22.

  As described above, the slide member 30 includes a pressing member 31 and a second housing 32 that supports the pressing member 31. The pressing member 31 of the present embodiment is a spring member having a shape in which a metal member is bent in two. The pressing member 31 as the spring member has a pressing portion 311 and a clamping portion 312. The pressing portion 311 presses the contact piece 211 of the female contact 21 and presses the contact piece 211 against the male contact 51 when the slide member 30 slides to the pressing position (see FIG. 6). Further, when the slide member 30 slides to the pressing position (see FIG. 6), the clamping unit 312 clamps the female contact side wall 212 with the pressing unit 311.

  As shown in FIG. 5, the male contact 51 is inserted into the connector 100. However, even if the male contact 51 is inserted, as long as the slide member 30 is in the release position shown in FIG. 5, the contact pressure of the female contact 21 with respect to the male contact 51 is lower than the predetermined contact pressure. The electrical connection of is not guaranteed.

  After the male contact 51 is inserted into the connector 100, the slide member 30 is slid to the pressing position shown in FIG. Then, the pressing portion 311 of the pressing member 31 provided in the slide member 30 presses the contact piece 211 of the female contact 21 to press the female contact 21 against the male contact 51. Thereby, the contact pressure between the male contact 51 and the female contact 21 becomes a prescribed contact pressure.

  Further, in the case of the present embodiment, the pressing member 30 includes a clamping portion 312. When the slide member 30 slides to the pressing position shown in FIG. 6, the holding unit 312 holds the side wall 212 of the female contact 21 between the holding unit 311.

  Here, it is assumed that the connector 100 vibrates due to external vibration. At this time, if the slide member 30 has a structure that vibrates relative to the contact sub-assembly 20, the contact pressure of the female contact 21 with respect to the male contact 51 fluctuates, causing slight sliding wear and Reliability may be reduced. In the case of this embodiment, the pressing member 31 holds the side wall 212 of the female contact 21. The female contact 21 is press-fitted into a first housing 22 that is a housing of the contact subassembly 20 and is integrated with the first housing 22. For this reason, in the case of this embodiment, the relative vibration between the slide member 30 and the contact subassembly 20 is suppressed, and when vibrating, they vibrate together. As long as they vibrate together, fluctuations in the contact pressure of the female contact 21 with respect to the male contact 51 can be suppressed. Thereby, generation | occurrence | production of fine sliding wear is suppressed and a highly reliable connector is implement | achieved.

  In the present embodiment, the pressing member 31 sandwiches a part of the contact subassembly 20, specifically, the side wall 212 of the female contact 21, so that the gap between the slide member 30 and the contact subassembly 20 is reduced. Relative vibration is suppressed. However, the present invention is not limited to a structure that sandwiches a part 212 of the female contact 21. For example, the pressing member may sandwich a part of the first housing 22 that is the housing of the contact subassembly 20, and the relative vibration between the slide member 30 and the contact subassembly 20 may be used. It is only necessary to have a relative vibration suppressing structure that suppresses the vibration.

  In the present embodiment, the single first housing 22 accommodates the five female contacts 21, but one first housing may be prepared for one female contact.
