Abstract

The invention discloses a contactor with a contact locking mechanism. The contactor comprises a base and an arc extinguishing chamber, wherein the arc extinguishing chamber can be detached from the base; a contact support and a locking mechanism are arranged on the base; the contact support can be locked by the locking mechanism after the arc extinguishing chamber is detached; the locking mechanism comprises a locking element; the locking element is arranged in the base in a rotatable way; a stopping wall matched with the lower arm of the locking element to limit the movement of the locking element is arranged on the base; the locking element comprises an upper arm which is matched with a clamping groove on the contact support for locking; a spring which drives the locking element to rotate is connected with the side wall of the locking element; and a first boss which is matched with the arc extinguishing chamber to separate the upper arm from the contact support is arranged on the side arm of the locking element. The contactor has the advantages of simple structure, small occupied space, practicability and firmness, and is reliable in locking.

Description

technical field [0001] The invention relates to a contactor with a contact locking mechanism. technical background [0002] Conventional contactors are generally equipped with a locking mechanism for contact support. After the arc chamber is removed, the contact support can be locked by the locking mechanism so that it does not move. For example, the locking mechanism of the contactor in patent No. 01804704.1 uses a lever that rotates around the deflection axis as the locking element. The movement of the locking element needs to be guided, which requires a good cooperation between the deflection axis and the guiding mechanism. Once the movement is completed, once there is an error in the fit, the locking element will not be able to lock the contact support, so that the reliability of the locking element is not high; and in order to keep the locking element on the bottom without being lost, another locking element is required To make the locking element clamped on the botto...
