A circuit breaker switch housing

Abstract

This utility model discloses a circuit breaker switch housing, which includes a housing and a first connector and a second connector disposed on the housing. The first connector includes a main body and an extension part that fits onto the main body. The surface wall of the extension part is provided with multiple equidistant annular grooves, and one side of the top of the extension part is provided with a cut extending towards the upper end face of the housing. The cut extends through the annular grooves, exposing the inner groove body in the cavity of the cut, thereby forming a guide channel for fastener ribs to be embedded. During connection and assembly, the operator needs to align the cut of the first connector with the ribs on the inner wall of the fastener, and then perform axial insertion. By relatively rotating and twisting the fastener or the first connector, the multiple ribs on the inner wall of the fastener can slide into the inner groove body of the annular groove along the cut, forming a multi-point snap-fit ​​mechanical interlock. This not only improves assembly efficiency, but also enhances the anti-torsion ability and anti-loosening performance after connection, and is especially suitable for working environments with frequent vibration or limited space.
