  • Patent number: 9859657
    Abstract: A connector apparatus includes first and second connectors. The first connector includes a first latching part, a second latching part, and an arm supporting the second latching part, and visible from an exterior. The second connector includes a first latched part to be latched with the first latching part, and a second latched part to be latched with the second latching part. The second connector is to be engaged with the first connector. In accordance with an advancement of the engagement between the first connector and the second connector, as the first latched part is latched by the first latching part, the second latching part is guided by the second latched part and the arm is deflected, and after the latching between the first latching part and the first latched part, as the second latched part is latched by the second latching part, the deflection of the arm is canceled.

  • Publication number: 20170250492
    Abstract: 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.
