Description

A copper bar rod body, an insulating rigid cable assembly and a power supply assembly

technical field

The utility model belongs to the technical field of connectors, in particular to a copper row rod body, an insulating rigid cable assembly and a power supply assembly.

Background technique

At present, copper bar type cable assemblies are generally insulated by PET film or paint powder process, and the end joints at the front end used for electrical connection with the internal contacts of the connector are contacted by welding or other methods to achieve contact conduction. There will be air bubbles inside the PET film lamination, and the sealing effect of the truncated surface after lamination of the PET film will be very poor. Generally, it is necessary to seal the glue around after lamination for insulation, and it is difficult to control the thickness of the powder spray for powder insulation. The shape and size control of several copper bars superimposed and pressed together are difficult for PET film and powder spraying to meet the requirements of high dimensional accuracy of the product. PET film and powder spraying are generally suitable for insulation processing of a single copper bar. When the cable end connector is installed by welding or screws, the assembly efficiency is low, it is inconvenient to disassemble during maintenance or repair, and the welding method is not convenient for operation under limited outdoor conditions, so it is impossible to inductively determine whether the welding reliability meets the expected standard.

Glue overflow grooves 203 are provided in the row insulating housing part 201 at the corresponding positions where the contact pieces 202 at both ends extend and protrude, so as to prevent the glue overflowing during the pressing process from causing the functional surface of the copper bar to be glued, that is, the surface of the contact pieces; the contact piece 202 Riveting nuts 204 are riveted and pressed at the bottom of the copper bar, and the riveting nuts 204 are forced into the copper bar insulator 3; The width of the segment may be different from the width of the contact segment.
