Problems solved by technology

[0004] Due to the opening on the side of the accommodating cavity, a slot is formed on the front side wall of the accommodating cavity, and at the same time, a through hole is formed on the top of the accommodating cavity, so that the overall strength of the accommodating cavity is weak, and the components installed in the accommodating cavity The conductive metal plate of the terminal is easy to loose, resulting in poor contact or arcing

Abstract

The invention discloses an anti-disengaging structure which comprises a body, a coil frame and a base. The coil frame is installed in the body, and a containing cavity with an opening in one side is formed in the coil frame. A first clamping plate and a second clamping plate are formed on the base, the body is installed on the base, the containing cavity is clamped between the first clamping plate and the second clamping plate, the first clamping plate is clamped in the opening, and the first clamping plate and the second clamping plate clamp the containing cavity. A clamping groove is formed in the side wall of the opening, a clamping block is formed on the first clamping plate, and the clamping block is clamped in the clamping groove. By means of the anti-disengaging structure, the containing cavity can be prevented from disengagement and deformation, and a wiring terminal conductive metal plate is effectively prevented from disengagement.

Description

technical field [0001] The invention relates to an anti-loosening structure, which is suitable for electrical equipment such as contactors and circuit breakers. Background technique [0002] In order to realize automatic assembly, an accommodation cavity is usually formed on the coil bobbin, and the side of the accommodation cavity is opened. The conductive metal plate is installed in the accommodation cavity and electrically connected with the coil. The screw is placed in the accommodation cavity through the side opening. In the accommodating cavity, a limiting mechanism that restricts the screw from falling off is formed. The limiting mechanism can be an elastic sheet, and a through hole is formed on the top of the accommodating cavity, and the through hole is used to lock the screw; the front side wall of the accommodating cavity forms a slot , the conductive metal plate is exposed, so that the probe can be directly in contact with the electric metal plate for detection d...
