Downsizing of a connector having a connector position assurance function
A connector includes an outer housing including an engagement catch, an inner housing and a sliding member. The inner housing includes an engagement latch, and a pair of locking arms each provided with the engagement latch. The inner housing includes a slide channel having the pair of locking arms disposed at both sides. The sliding member includes a pair of latching arms each provided with a latch. When the first housing and the second housing are engaged with each other, the first housing and the second housing allow the sliding member to pass through the slide channel, and when the sliding member slides the slide channel, the pair of latching arms are deflected so as to decrease a gap therebetween by depressions from the respective locking arms.
1. A connector comprising:
a first housing comprising an engagement catch;
a second housing comprising an engagement latch to latch the engagement catch, a pair of locking arms each provided with the engagement latch, and a slide channel having the pair of locking arms disposed at both sides, the second housing being to be engaged with the first housing; and
a sliding member comprising a pair of arms each provided with a latch,
wherein:
when the first housing and the second housing are engaged with each other, the first housing and the second housing allow the sliding member to pass through the slide channel; and
when the sliding member slides the slide channel, the pair of arms are deflected so as to decrease a gap therebetween by depressions from the respective locking arms, and when the latches go over the respective locking arms, the gap between the pair of arms increases, the increase in the gap enabling the locking arms to be latched by the respective latches.
2. The connector according to claim 1 , wherein:
the sliding member comprises a protrusion; and
the engagement latch is latched by the protrusion to restrict a sliding action of the sliding member until the engagement catch is latched by the engagement latch for the engagement between the first and second housings, when the engagement catch is latched by the engagement latch, the latching between the protrusion and the engagement latch is canceled and the canceling of the latching between the protrusion and the engagement latch enables the sliding member to pass through the slide channel.
3. The connector according to claim 1 , wherein the pair of arms each comprise a tentative latch that prevents a movement in an opposite direction to the sliding action upon latching each of the locking arms of the second housing, the tentative latch being provided ahead of the latch toward a leading end.
4. The connector according to claim 1 , wherein the respective latches of the pair of arms are formed in a shape protruding outwardly relative to each other.
5. 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.
