Embodiment Construction

[0028] The switchgear shown in the figure is a low-voltage single-pole circuit breaker 10, the circuit breaker 10 has a molded housing 12 made of synthetic insulating material, the housing 12 by the base 14 and A cover 16 at the front is formed. The cover 16 includes: a front panel 17 partially covered by an auxiliary cover plate 18; serrated side panels 19a, 19b; and lateral panels 20, 21. A part of the base 14 of the component includes a rear panel 22 opposite to the front panel 17 of the cover 16, side panels 23a, 23b, and lateral panels 24, 25. The cover 16 is mounted on the base 14, and the geometric joint surface is located at the height of the side panel and the edge of the lateral panel of the base and the cover. In this way, the assembled shell is similar to a parallelepiped, and there are two larger-sized The side surfaces 24a, 24b and two relatively narrow lateral surfaces 26, 28 that are largely cut away. In other words, the device housing can be located in a geometric...

Abstract

An electric switch device, especially a circuit breaker, comprises a housing (12) composed of a socket (14) and a cover (16) fixed with each other by clamps (30a, 30b). The clamps are arranged in grooves (42a, 42b) formed on side panels (24a, 24b) of the housing, and are folded at a front panel (17) of the cover (16) and a rear panel of the socket (14). The cover (16) is provided with an opening (46) for passing a handle (88) of a device mechanism. A detachable contact head of a driving device of the mechanism performs a planar motion in a plane parallel with the side panels of the housing.

Description

Technical field [0001] The present invention relates to a low-voltage electrical switchgear. This type of electrical switchgear includes a rigid housing made of insulating synthetic material and equipped with detachable contacts and a drive mechanism for these contacts. In particular, the present invention relates to a method of fixing components to form the housing of the device. technical background [0002] The housing of a multi-pole, high power rated electrical switchgear is usually formed of at least two parts, among which are: a base designed to support power terminals for electrical connection of the device; and at least one cover. The housing defines a housing for the separable contact and the drive mechanism of the contact, and the separable contact is connected to the power terminal. The cover usually includes at least one opening to allow the operation, control or display device of the device to pass through. When necessary, the cover has a rece...
