Protection cover rotating assembling structure and contactor with structure

Abstract

The invention relates to a protection cover rotating assembling structure and a contactor with the structure. The rotating assembling structure is used for installing a protection cover (2) on a shell (1) and comprises an inclined surface limiting mechanism. The inclined surface limiting mechanism comprises a first step matching inclined surface (511) which is arranged on an insulated retaining wall (11) and a second step matching inclined surface (611) which is arranged on a side wall (22) and is matched with the first step matching inclined surface (511). The inclined surface limiting mechanism is used for limiting the protection cover (2) from moving upwards in a Y direction after the protection cover is installed on the shell (1). The protection cover rotating assembling structure and the contactor with the structure have the advantages that the fixed limiting reliability of the protection cover is high, the position of the shortest leakage path calculation point of the contactor is higher and the shortest leakage path is enabled to more easily satisfy the product requirements.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a rotating assembly structure of a protective cover and a contactor with the structure. Background technique [0002] A contactor is a non-manually operated mechanical switching device that can carry and frequently switch on and off normal circuit current. With the rapid development of the field of low-voltage electrical appliances, the market has put forward higher requirements for the miniaturization, personalization and insulation performance of contactor products. [0003] At present, a widely used contactor includes a shell structure composed of a shell and a protective cover, and a number of phase live conductors composed of tile-shaped terminal screws, contact plates and terminals, etc., which are located in the shell structure. Widely used are contactors with four-phase live conductors. Affected by factors such as the product's inherent structu...

Problems solved by technology

[0010] For this reason, the technical problem to be solved by the present invention lies in the low reliability of the fixed position limit for the upward movement of the protective cover in the Y direction by the rotating assembly structure of the protective cover in the prior art, and because the position of the calculation point of the shortest leakage path is low, resulting in contactor products To solve the problem that the shortest leakage path is difficult to meet the requirements, a protective cover rotation assembly structure with high reliability for the fixed position limit of the protective cover and a higher position of the calculation point of the shortest leakage path is provided, which makes it easier for the shortest leakage path to meet the requirements.
