Abstract

A connector includes an outer housing, an inner housing provided with an engagement latch, a slide channel, and rails each being a groove, and a sliding member provided with support arms engaged with the respective rails, and a protrusion to latch the engagement latch. The slide channel is formed with a slide surface extending along the rail. The support arms each include a lower surface facing the slide surface, and an upper surface inclined relative to the slide surface. The groove forming the rail is formed as a recess including a bottom surface, a first side surface, and a second side surface. The second side surface faces the upper surface of the support arm, and is formed at an inclination angle corresponding to that of the upper surface.

Claims

1. A connector comprising:

a first housing;

a second housing comprising a protrusion catch, a slide channel, and a rail formed as a groove along the slide channel, the second housing being to be engaged with the first housing; and

a sliding member comprising a support arm to be engaged with the rail upon engagement with the groove, and a protrusion to latch the protrusion catch, the sliding member being placed in the slide channel,

wherein;

the slide channel is formed with a slide surface extended along the rail;

the support arm comprises a first surface facing the slide surface, and a second surface formed at a back side of the first surface, and inclined relative to the slide surface;

the groove is formed as a recess that includes a bottom surface, a first side surface, and a second side surface;

the second side surface faces the second surface of the support arm, and is formed at an inclination angle corresponding to an inclination angle of the second surface; and

when the first housing and the second housing are engaged with each other, the first housing depresses the protrusion latching the protrusion catch of the second housing to cancel a latching between the protrusion catch and the protrusion, enabling the sliding member to be slidable.

2. The connector according to claim 1, wherein:

the second housing comprises a pair of ribs formed along a direction in which the slide channel extends; and

the groove is formed in each of the pair of ribs.

3. The connector according to claim 1, wherein:

the sliding member comprises a pair of the support arms; and

the second surface of the support arm is formed so as to be inclined in a direction in which the pair of support arms face each other.

4. The connector according to claim 1, wherein a leading end part of the support arm is formed with a guide surface that guides the sliding member into the groove.

5. The connector according to claim 1, wherein:

the support arm comprises a first support arm part, and a second support arm part extending from an end of the first support arm part, and having a smaller lateral cross-sectional area than a lateral cross-sectional area of the first support arm part; and

the rail comprises a first rail part to be engaged with the first support arm part, and a second rail part to be engaged with the second support arm part.

6. The connector according to claim 1, wherein:

a catch is disposed at the slide channel; and

the sliding member comprises a latching arm including a latch to latch the catch.

7. The connector according to claim 6, wherein:

a leading end part of the support arm and a leading end part of the latching arm are located at a same position in a lengthwise direction; and

a protrusion protruding in a direction in which the support arm and the latching arm face each other is formed on a leading end part of at least either the support arm and the latching arm.

8. The connector according to claim 6, wherein a guide surface that guides the sliding member into the slide channel is formed at a leading end part of the latching arm.

9. The connector according to claim 1, wherein:

the first housing comprises an engagement catch; and

the second housing comprises an engagement latch to latch the engagement catch, and also serving as the protrusion catch.

10. The connector according to claim 1, wherein the respective first and second housings are housings of the connector that comprises a terminal connected to a wiring.
