First connector, second connector and connector assembly

Abstract

This invention proposes a first connector including a first detection unit. When the first connector is inserted into a second connector including a second detection unit, the first detection unit of the first connector and the second detection unit of the second connector are electrically connected to form an electrical detection circuit. The first connector includes an inner housing and an outer housing positioned outside the inner housing. The first detection unit is at least partially disposed between the inner housing and the outer housing. This invention also proposes a second connector, a connector assembly, and an electrical connection detection assembly. Accordingly, the insertion of the first and second connectors can be determined accurately and intuitively, and the cooperation between the first and second detection units is facilitated.
