Problems solved by technology

However, the outer conductor of the SMA curved RF coaxial connector currently used is generally made of stainless steel by adding solder and then using manual arc welding, manual tungsten argon arc welding and gas welding. However, this type of welding method is not suitable for precision small parts However, due to factors such as high welding temperature, long welding cycle, and large welding area, the dimensional accuracy of the parts cannot be guaranteed
Therefore, the torque resistance of the two welded parts in the SMA curved RF coaxial connector is small and cannot meet the requirements

Embodiment 1

[0015] Embodiment 1: A method for manufacturing the outer conductor of a high-performance cable connector, the method is to laser weld two shells made of austenitic stainless steel 303 materials together along a circular track at the seams of the two, Forms the outer conductor of the SMA angled RF coaxial connector.

[0016] During laser welding, the laser beam is aimed at the part to be welded for laser welding. The laser beam spot diameter is 0.5mm, the defocus is +1mm, the pulse frequency is 30Hz, the voltage is 80V, and the welding speed is 3-6mm / s.

[0017] The invention adopts laser welding, which is to weld two materials together through the high temperature generated by the laser beam without adding solder; because the laser beam can form a "light column" within a diameter of 0.5 mm and run along the set track, thereby realizing local welding. The material is thermally melted to achieve the purpose of welding.

[0018] In the present invention, the seams of the two sh...

Abstract

The invention discloses a production method for an outer conductor of a high performance cable connector. Two outer casings which are made of austenitic stainless steel 303 materials are welded at seams of the two outer casings along circumferential laser. According to the production method for the outer conductor of a high performance cable connector, the variation of the size of the welded parts is within 0.005 mm which completely satisfies the size accuracy requirement; the endurance distance between two parts after welding can achieve 6 N.m which completely satisfies mechanical performance requirement; materials are saved, the performance is stable, and the costs are low; laser welding is performed between the two outer casings through the stainless steel materials to guarantee stable and reliable structure of the outer conductor, meanwhile different sized pressure welding points can be welded according to different cable, so that a standard part is formed, materials are saved, and costs are reduced; the application environment is wide; the connector produced through the method can be applied to various atrocious weather conditions and is good in corrosion resistance performance and high temperature resistant.

Description

technical field [0001] The invention relates to a production of a cable connector, in particular to a production method of an outer conductor of a high-performance cable connector. Background technique [0002] Cable connectors are mainly suitable for signal transmission between various digital program-controlled switches in transmission equipment bureaus, internal connections of photoelectric transmission equipment and distribution frames, and are used to transmit data, audio, video and other communication equipment. The sheath is made of flame retardant material with high safety factor. Adopting advanced technology to produce, the flame retardant and anti-uniformity of the cable is good, and the multi-core cable makes the rack laying more convenient. However, the outer conductor of the SMA curved RF coaxial connector currently used is generally made of stainless steel by adding solder and then using manual arc welding, manual tungsten argon arc welding, and gas welding. ...
