Embodiment Construction

[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] The specific embodiment of the isolated ground combination switch of the present invention, as Figure 1 to Figure 2 As shown, the isolating and grounding combination switch includes an isolating switch mechanism and a grounding switch mechanism. The grounding switch mechanism includes a moving end contact seat 1 of the earthing switch, a static end contact seat assembly 2 of the earthing switch, and a socket installed on the moving end contact seat 1 of the earthing switch for guiding movement. The grounding start contact rod 3 in the hole, when the grounding switch contact rod 3 is in the grounding position 3' of the grounding switch, the grounding switch is in the ON state. The isolating switch mechanism includes the isolating switch moving end contact seat 7 and the isolating switch contact rod 5 which is guided and moved and assembled in the ...

Abstract

The invention relates to a contact base, a contact base assembly with the contact base and an isolation ground-connection combination switch with the contact base. The front end of the contact base in the contact base assembly of the isolation ground-connection combination switch is folded backwards to form an umbrella skirt edge with an opening backwards, so that point discharge is avoided; a shielding case is arranged at the rear end of the umbrella skirt edge and backwards exceeds the rear end of a contact base body, so that the problem that the shielding case generates interference to cause shielding case deformation failure when a corresponding contact rod is inserted into a plug hole of the contact base is solved.

Description

technical field [0001] The invention relates to a contact seat, a contact seat assembly using the contact seat, and an isolating and grounding combined switch. Background technique [0002] The isolating and grounding combination switch includes an isolating switch and a grounding switch. The isolating switch and the grounding switch realize the circuit connection through the corresponding contact rod and contact seat. The mating position is shielded. The shielding cover on the contact seat in the prior art generally opens towards the insertion direction, so that the corresponding contact rod is easy to collide with the shielding cover when it is mated with the socket of the contact seat, causing the shielding cover to deform. , causing the problem of shielding failure. Contents of the invention [0003] The purpose of the present invention is to provide a contact seat to solve the problem of shielding failure caused by deformation of the shield when the corresponding con...
