Laser welding type quick-plug connector

Abstract

The invention discloses a laser welding type quick-plug connector which is used for connecting a first pipe fitting and a second pipe fitting in an automobile pipeline. The laser welding type quick-plug connector comprises a female connector and a male connector, wherein the male connector is arranged in the female connector in a pluggable mode; the female connector comprises a female connector body, one end of the female connector body is a female connector quick-plug end, the other end of the female connector body is a female connector welding end which is hermetically fixed to the first pipe fitting through laser welding, and the female connector quick-plug end is provided with an elastic locking spring; the male connector comprises a male connector body, one end of the male connector body is a male connector quick-plug end, and the other end of the male connector body is a male connector connecting end which is fixedly connected with the second pipe fitting; and the outer surface of the male connector quick-plug end is annularly provided with a first clamping ring groove, and the first clamping ring groove is used for clamping and fixing the elastic locking spring to make the male connector quick-plug end and the female connector quick-plug end to be clamped and fixed, so that the male connector and the female connector are quickly assembled and disassembled, the number ofparts is greatly reduced, the processing cost is reduced, and the matching difficulty among the parts is reduced.

Description

technical field [0001] The invention relates to the technical field of quick-plug joints of automobile fluid transmission pipelines, and more particularly relates to a laser-welded quick-plug joint. Background technique [0002] At present, there are generally two types of quick-connect connectors for automotive fluid transmission nylon pipes on the market: one is the bamboo-type male-female joint with tubes and is used for locking. Poor, high temperature stretchability, high temperature pressure resistance and blasting performance are poor, the sharp corners of the bamboo joints of metal parts are difficult to ensure the sealing and stretchability, and the high and low temperature alternating sealing performance of the bamboo joints of injection molded parts and nylon tubes is poor; the other It is an in-line push-in connector. One end of the connector is installed on the vehicle valve body (or pump body), and the nylon tube empty tube is inserted into the connector and aut...

[0002] At present, there are generally two types of quick-connect connectors for automotive fluid transmission nylon pipes on the market: one is the bamboo-type male-female joint with tubes and is used for locking. Poor, high temperature stretchability, high temperature pressure resistance and blasting performance are poor, the sharp corners of the bamboo joints of metal parts are difficult to ensure the sealing and stretchability, and the high and low temperature alternating sealing performance of the bamboo joints of injection molded parts and nylon tubes is poor; the other It is an in-line push-in connector. One end of the connector is installed on the vehicle valve body (or pump body), and the nylon tube empty tube is inserted into the connector and automatically locked and connected.

[0003] Among them, the in-line quick-plug connector can also be divided into two types according to the way of use. One is the easy-to-lock and easy-to-open quick-connect connector, which has a simple structure and is suitable for the gas circuit connection of pneumatic equipment tooling, but not suitable for heavy truck commercial vehicle pneumatic systems. There is a safety risk that it is easy to disengage and cause the brake to fail; the other is a quick-plug joint that is easy to lock and difficult to open, and its structure is complex and the risk factor is high.

The plug-in quick-connect joint can also be divided into two types according to the material: one is the joint of the metal main part and the rubber sealing ring. The other is that the external parts are injection molded parts, and the internal parts are metal parts and rubber parts, which are easy to assemble and disassemble, but it is prone to artificial or non-artificial trachea falling off, which poses a safety risk

[0004] To sum up, the in-line push-in connector in the prior art has complex structure, many parts, high processing cost, difficult to guarantee the quality of the parts, difficult to control the mutual cooperation between the parts, and prone to man-made or Non-artificial shedding of the tube body, there are problems such as greater safety risks
