Description

Connector and connector assembly

Technical Field

The present utility model relates to a connector and a connector assembly including the same.

Background

In the prior art, a connector generally includes a housing, a pair of plate terminals, and a pair of connection plates. A pair of plate-like terminals are mounted in the housing and are opposed at a spacing in the lateral direction of the housing. A pair of connection plates are respectively connected to and extend from the rear ends of the pair of plate-like terminals for respectively electrically connecting to the electrical transmission members. In the prior art, a pair of stopper ribs are formed on the top wall and the bottom wall of the housing, respectively. A pair of stopper ribs are respectively abutted against the inner sides of the front ends of the pair of connecting plates for positioning the connecting plates and the plate-like terminals in the lateral direction of the housing.
