Embodiment Construction

[0009] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0010] The present invention is mainly composed of clip-type synchronous electrical connectors 1 and 2, drop-out fuse body 3, connector body 4, clip block seat 5, full-circle anti-loosening gasket 6, flange nut 7 and the like.

[0011] In the present invention, a clip-type synchronous electrical connector 1 and a clip-type synchronous electrical connector 2 are respectively installed at both ends of the drop-out fuse body 3 .

[0012] The clamp-type synchronous electrical connectors 1 and 2 of the present invention are respectively composed of a connector body 4 , a clamping block seat 5 , a full circle anti-loosening washer 6 and a flange nut 7 . The lower part of the connector body 4 is a threading hole, and the upper part is a bolt structure, which is composed of a flange nut 7, a full-circle anti-loosening washer 6, and a clamping block seat 5 to f...

Abstract

This invention relates to an on-line drop-off fuse, in which, two wiring clips synchronous connectors are installed on both ends of the fuse composed of connectors, clip block bases, ring anti-loosing pads and collar nuts. This invention realizes the aim of non-power cut by contacting the connector with a lead directly and screwing the nut anticlockwise by an on-line quick tool to drive the clamp plate to move upward to install the lead or screwing the nut clockwise to drive the clamp plate to move downward to clamp the lead.

Description

technical field [0001] The invention relates to a non-stop drop-out fuse, in particular to a short-circuit protection switch most commonly used in 10kv distribution lines and distribution transformers. Background technique [0002] Before the present invention is made, in prior art, be used for the connection of electrical appliances such as 10kv distribution line and distribution transformer to adopt manual operation usually, and can only work when power failure. Therefore, the power outage time is long when the connector is replaced, and its conductive path is transmitted from the two ribs on the bottom plate to the wire, so the path for power transmission is long, the contact area is small, and the loss of the power grid is large. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a connector body in direct contact with the wire, which is convenient and reliable in connection, simple in opera...
