AI Technical Summary

Technical Problem

In the prior art, the current is easily interrupted when the connector is pulled out in the semi-engaged state, and the engagement completion state cannot be reliably detected.

Method used

A connector assembly is designed, wherein a first connector includes a first housing and a first mating detection terminal, and a second connector includes a second housing and a second mating detection terminal. Through the elastic deformation and recovery of the spring portion, it is ensured that the second mating detection terminal is conductive with the first mating detection terminal when mating is completed.

Benefits of technology

It enables reliable detection of the engagement state after engagement is completed, avoiding current interruption caused by removal and ensuring the stability of the electrical connection.

Abstract

The present application provides a connector assembly capable of reliably detecting fitting after fitting is completed. When fitting operation of a first connector and a second connector is started, a spring body (14E) is elastically deformed by a protrusion (pressing portion) (22E) of a second housing (22) contacting a pressed portion (14F) of a spring portion (14B) of a first fitting detection terminal (14), a second contact is not in contact with a first contact and the second connector advances, when fitting operation is completed, the elastic deformation of the spring body is restored by the pressed portion of the spring portion of the second housing contacting the pressed portion, the second contact is in contact with the first contact, and the second fitting detection terminal is in conduction with the first fitting detection terminal (14).
