Wiring pile head convenient to manufacture in batched mode

Abstract

The invention relates to a wiring pile head convenient to manufacture in a batched mode and belongs to the field of power supply. A porcelain insulator is composed of an upper porcelain insulator assembly and a lower porcelain insulator assembly which are buckled in an up-and-down split mode. An upper porcelain insulator body penetrates through a wire outlet open hole from the outer portion of a box body and is connected with a lower porcelain insulator body located in the box body in a plugging mode, and the upper porcelain insulator body and the lower porcelain insulator body are buckled into a whole. Central penetrating holes are formed in the upper porcelain insulator body and the lower porcelain insulator body, an integrated conductive copper bar is arranged in the central penetrating holes, penetrates through a rainproof cap, passes through the central penetrating holes of the upper porcelain insulator body and the lower porcelain insulator body and then penetrates out of the central penetrating hole of the porcelain insulator body, the part, forming an external wiring terminal, of the conductive copper bar and the rainproof cap are welded and fixedly connected into a whole, a threaded structure is formed in the part, forming an inner wiring terminal of the box body, of the conductive copper bar, and a locking nut is arranged between the conductive copper bar of the inner wiring terminal and the lower porcelain insulator body. The conductive copper bar drives the rainproof cap to fix the upper porcelain insulator body and the lower porcelain insulator in the wire outlet open hole by screwing the locking nut.

Description

technical field [0001] The invention belongs to the field of power supply and distribution, in particular to an insulated wiring pile head used for a switch box. Background technique [0002] The outdoor low-voltage protection switch box is one of the important equipment in the outdoor pole transformer device of the low-voltage power distribution network. It is installed between the low-voltage end of the transformer and the low-voltage power grid. "Split" and "Close" to realize the input and cut-off operation of the low-voltage power grid. [0003] In the widely used outdoor low-voltage protection switch box at present, the outlet terminal is connected with the screw rod by the terminal pile head, and is insulated from the low-voltage protection switch box body through an insulator. The hoop-type connecting plate is converted and transitioned, and the hoop-type connecting plate is used as an intermediate connecting part to increase the resistance value of the entire connec...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a wiring pile head that is convenient for mass production. It adopts the structure of a combined porcelain bottle assembly and an integrated conductive rod. The cycle is long, the aging resistance of the product is poor, and the actual effective service life is short. On the other hand, due to the use of the combined porcelain bottle component structure, the insulator has high temperature resistance, tensile strength, bending strength, high density, and aging resistance. and other performance, which improves the reliability of power supply and facilitates mass production
