Manufacture method of waterproof power connector and waterproof connector adopting same

Abstract

The invention discloses a manufacture method of a waterproof power connector, comprising the following steps: firstly, cutting a power cord with needed length; then peeling off the skin of a core cord at one end of the power cord so that a metal conducting wire is exposed to the outside; then placing the metal conducting wire into a terminal machine and respectively performing compression joint to a metal male terminal and a metal female terminal; next, sleeving a hard insulating sleeve outside the metal female terminal; and then placing the power cord of the connected metal male terminal into a male connector mould, placing the power cord of the connected metal female terminal into a female connector mould, injecting and molding a male connector and a female connector by an injection molding way, and selecting hard plastic as the material of the male connector and the female connector. By adopting a hard plastic injection molding way to manufacture the connector, the invention has simple process and good waterproof effect compared with a combined waterproof connector in the prior art.

Description

【Technical field】 [0001] The invention relates to a connection joint, in particular to a method for making a waterproof power supply joint and a waterproof joint using the method. 【Background technique】 [0002] In order to facilitate packaging, transportation, replacement, and future maintenance, various lamps, electrical appliances, and wires and cables generally use detachable joints, but detachable joints are easily corroded by rainwater when used outdoors, and leakage and short circuits occur, especially in Lamps and electrical appliances used underwater have stricter requirements on the waterproof performance of the joints. In the prior art, male and female joints are mostly used for connection. In order to achieve a good waterproof effect, waterproof rubber rings are also provided at the connection ends of the male and female joints. For example, the Chinese Patent Publication No. is CN201180977Y, which discloses a new type of waterproof joint, including a male joint...

AI Technical Summary

Problems solved by technology

When manufacturing the above-mentioned patented products, the male joints, female joints, lock rings, middle sleeves, wire clamps, and compression nuts all need special molds to make. After the production is completed, a production assembly line is required to assemble these parts. Production The production cost is very high, and the male and female pins can only be fixed by manual glue, and the yield rate of the product is very low; at the same time, the product has five threads and nut connections, which are easy to be used in heavy rain erosion or underwater use. Ingress of water, so there is a great potential safety hazard
