  • Patent number: 10923854
    Abstract: A connector body includes mating guide parts formed on each longitudinal end and mating with counterpart mating guide parts formed on both longitudinal ends of a counterpart connector body of a counterpart connector. Each reinforcing bracket includes a pair of left/right slide guides disposed on the mating guide parts and being engageable with a pair of left/right slide engagement parts of a counterpart reinforcing bracket mounted to a counterpart mating guide part. One reinforcing bracket further includes a receiving member capable of emerging/submerging. When the counterpart mating guide part is mated with the mating guide part, the receiving member submerges. When the slide engagement part engages with the slide guide and the counterpart mating guide part slides on the mating guide part, the receiving member emerges and latches the counterpart mating guide part.

  • Patent number: 10594077
    Abstract: A connector includes a connector body, terminals installed in the connector body, and lock devices fit to the connector body. The connector body includes mating guide parts that are formed on both ends of the connector body in a longitudinal direction and are fit in mating-connector-side mating guide parts formed on both ends of a mating connector body of a mating connector in the longitudinal direction. The lock devices include sliders attached to the mating guide parts to be slidable in the longitudinal direction of the connector body. The sliders each include a pair of right and left locking protrusions. When the connector body is mated with the mating connector body, the locking protrusions engage with mating reinforcement brackets installed on the mating connector body.
