Embodiment Construction

[0009] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0010] Such as figure 2 As shown, a conductive contact spring finger connection device provided by the present invention is only composed of four parts: conductor 8 , spring finger 10 , contact 9 , and guide rod 11 . Process the conductor 8 and the contact 9 according to the inner diameter, outer diameter and compression amount of the spring contact finger 10. When assembling and connecting, put the spring contact finger 10 into the groove on the inner surface of the contact 9, then screw the guide rod 11 into the contact 9, then insert the conductor 8 into the contact 9 along the guide rod 11, and compress the spring contact finger 10 , The spring contact finger 10 produces elastic deformation force (contact pressure), so that the conductor 11, the spring contact finger 10 and the contact 9 are closely connected. When in use, ...

Abstract

The technical solution of the present invention is to provide a conductive contact spring contact finger connection device, which is characterized in that: it includes a conductor, the end of the conductor is covered with a contact, and a groove is opened at the contact point between the inner wall of the contact and the conductor. The spring contact finger is embedded in the groove, one end of the guide rod is fixed on the contact, and the other end is inserted into the end of the conductor. The invention has the advantages of simple structure, few parts, strong current-carrying capacity and low cost (it is about 65% of the plum blossom contact plug-in connection).

Description

technical field [0001] The invention relates to a spring contact finger connection device for conductive contacts, which is used for the connection between contacts in a gas-insulated metal-enclosed switchgear (hereinafter referred to as GIS), and belongs to the technical field of high-voltage electrical appliances. Background technique [0002] The connection between the contacts in the gas-insulated metal-enclosed switchgear (GIS) currently adopts the plum blossom contact plug-in connection device. Such as figure 1 As shown, the connecting device is generally composed of a contact base 1, a spring 2, a set of plum contact fingers 3, a guide plate 4, a guide rod 5, a shield 6, and a conductor 7 (diameter 90mm). Among them, a group of plum blossom contact fingers 3 is composed of 16 to 32 contact fingers. Therefore, this connection method has a maximum of 32 contact points, and its flow capacity is limited to a certain extent (maximum current flow is 4000A). If you want to ...
