A protective cover rotation assembly structure and a contactor with the structure

Abstract

A rotating assembly structure for a protective cover and contactor having said structure, the rotating assembly structure being used to install a protective cover (2) on a housing (1) and comprising an inclined-face limiting mechanism, said mechanism itself comprising a first-step inclined face (511) provided upon an insulating wall (11) and a second-step inclined face (611) provided upon a side wall (22) for matching said first-step inclined face (511), said limiting mechanism being used for limiting the upward movement in direction Y of the protective cover (2) when installed on the housing (1). The present assembly structure is highly reliable in terms of fixing the position of the protective cover, and the calculating point of the shortest leakage path of the contactor is relatively high, allowing the shortest leakage path thus more easily to meet equipment 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.
