Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0020] Such as figure 1 , figure 2 and image 3 As shown: In order to improve the reliability of the drawer-type switch cabinet adapter socket and reduce the temperature rise caused by the load current, the present invention includes a static contact assembly 2, which includes a first contact opening 5 and a The second contact opening 6 corresponding to the first contact opening 5; the second contact opening 6 of the static contact assembly 2 extends into the insulating protective cover 1 after passing through the insulating support 3, and the second contact The opening 6 communicates with the insertion opening 7 on the insulating shield 1; the opening degree α of the insertion opening 7 is 20°-40°.

[0021] Specifically, the first contact opening 5 of the static contact assembly 2 is used to insert into the busbar of the power switch cabinet, the second co...

Abstract

The invention relates to a multi-tap for a power switch cabinet drawer. The multi-tap comprises a fixed contact module. The fixed contact module comprises a first contact opening and a second contact opening corresponding to the first contact opening, the second contact opening of the fixed contact module penetrates through an insulation supporting piece and then extends into an insulation protective cover, the second contact opening is communicated with an inserting opening of the insulation protective cover, and the opening degree of the inserting opening is 20-40 degrees. According to the multi-tap for the power switch cabinet drawer, the insulation protective cover is thickened, the strength of the insulation protective cover is improved, the opening degree of the inserting opening is set to be 20-40 degrees, and preferably is 30 degrees, and the inserting front end of the inserting opening is in an arc shape; in addition, a reinforcing rib is installed on the insulation supporting piece to a play a role in resisting the inserting strength and deformation, inserting displacement, inclination and heating phenomenon are effectively overcome, the combining ability of contacts is improved, and the heating phenomenon caused by poor contact in the contact combining process can also be avoided.

Description

technical field [0001] The invention relates to an adapter socket, in particular to an adapter socket used for a drawer of a power switch cabinet, and belongs to the technical field of the adapter socket of the power switch cabinet. Background technique [0002] At present, in the drawer of the power switch cabinet, the connection of the adapter socket directly affects the heating caused by the current that the drawer bears and the contact tightness of the drawer. In most power drawer cabinet applications, accidents are not uncommon due to poor connection of sockets, especially in places where power outages are strictly prohibited in some important occasions, heating and damage to components due to poor contact of drawer sockets also occur from time to time. At the same time, because the drawer type switchgear has the characteristics of convenient maintenance and replacement, it is welcomed by customers. However, the transfer sockets of the existing drawer-type switch cabin...
