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, a connector having the above structure, which is planned to be mounted in a place where vibration is large, such as inside an automobile, is known.

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 which is a mating contact by inserting an insertion member into a female contact housed in a housing.

Japanese Unexamined Patent Publication No. 2013-93318

The above-mentioned Patent Document 1 describes that the connector having the structure disclosed therein can be miniaturized 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 slight sliding wear and lowering the reliability. There is a risk of

In view of the above circumstances, it is an object of the present invention 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 vibration is received from the outside.

The connector of the present invention that achieves the above object is
A contact subassembly with a female contact and a first housing that supports the female contact,
A pressing member deployed 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 while sliding to the pressing position, and the pressing member. It has a second housing that supports, and accommodates a sliding member that is slidable between the pressing position and the release position where the male contact is released from the pressing of the female contact, and the contact subassembly. Equipped with a frame that guides the slide of the slide member,
The slide member is characterized by having a relative vibration suppression 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 vibrate relatively when receiving 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 pressing member has a relative vibration suppressing structure, a change in the 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 metal member bent in half and elastically sandwiches a part of the contact subassembly by sliding to the pressing position. By pressing the female contact against the male contact inserted into the female contact and sandwiching a part of the contact subassembly in a state where the slide member slides to the pressing position. It is preferable that the member suppresses the relative vibration between the contact subassembly and the slide member.

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 in which a metal member is bent. A slide member provided with a pressing member having this structure can have an action of pressing a female contact against a male contact and an action of suppressing relative vibration.

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

The connector 100 includes a frame body 10 made of an insulating resin, a contact subassembly 20, and a slide member 30.

The contact subassembly 20 has a female contact 21 made of a conductive metal and a first housing 22 made of an insulating resin that supports the female contact 21. Five female contacts 21 are arranged in the contact subassembly 20 of the present embodiment.

Further, the slide member 30 has a pressing member 31 and a second housing 32 made of an insulating resin that supports the pressing member 31. As shown in FIG. 1, the slide member 30 slides between a release position protruding from the frame body 10 and a pressing position (see FIG. 6) pushed into the frame body 10. In the slide member 30 of the present embodiment, five pressing members 31 are arranged corresponding to the five female contacts 21 provided in the contact subassembly 20.

Further, the frame body 10 accommodates the contact subassembly 20 and guides the slide of the slide member 30.

The connector 100 is mounted on the circuit board 200. Then, the circuit board 200 is formed with a through hole 201 through which the male contact 51 penetrates. 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, the five male contacts 51 penetrate through the through holes 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 along the arrows AA shown in FIG.

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

Further, FIG. 5 is a cross-sectional view of a state in which 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 open position.

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

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

Further, 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 metal member bent in two. The pressing member 31 as the spring member has a pressing portion 311 and a holding portion 312. When the slide member 30 slides to the pressing position (see FIG. 6), the pressing portion 311 pushes the contact piece 211 of the female contact 21 and presses the contact piece 211 against the male contact 51. Further, when the slide member 30 slides to the pressing position (see FIG. 6), the sandwiching portion 312 sandwiches the side wall 212 of the female contact with the pressing portion 311.

As shown in FIG. 5, a 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 specified contact pressure, and between those contacts. Electrical connection is not guaranteed.

After inserting the male contact 51 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 on the slide member 30 pushes the contact piece 211 of the female contact 21 to press the female contact 21 against the male contact 51. As a result, the contact pressure between the male contact 51 and the female contact 21 becomes the specified contact pressure.

Further, in the case of the present embodiment, the pressing member 30 includes a holding portion 312. Then, when the slide member 30 slides to the pressing position shown in FIG. 6, the sandwiching portion 312 sandwiches the side wall 212 of the female contact 21 with the pressing portion 311.

Here, it is assumed that the connector 100 vibrates in response to vibration from the outside. At this time, if the slide member 30 has a structure that vibrates relative to the contact subassembly 20, the contact pressure of the female contact 21 with respect to the male contact 51 fluctuates, causing slight sliding wear to form a connector. Reliability may decrease. In the case of the present embodiment, the pressing member 31 sandwiches the side wall 212 of the female contact 21. The female contact 21 is press-fitted into the first housing 22, which is the housing of the contact subassembly 20, and is integrated with the first housing 22. Therefore, in the case of the present embodiment, the relative vibration between the slide member 30 and the contact subassembly 20 is suppressed, and when they vibrate, they vibrate as one. 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. As a result, the occurrence of slight sliding wear is suppressed, and a highly reliable connector is realized.

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 slide member 30 and the contact subassembly 20 are sandwiched between the slide member 30 and the contact subassembly 20. 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 which is the housing of the contact subassembly 20, and the relative vibration between the slide member 30 and the contact subassembly 20. It suffices to have a relative vibration suppression structure that suppresses.

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