Problems solved by technology

'The common welding method is often to directly set a guide hole in the shell, and then directly weld the coaxial cable on the guide hole. However, in the existing microwave communication devices, there is no structure for fixing the cable on the cavity. The welding position between the cable and the cavity cannot be positioned accurately, which leads to poor welding effect and poor welding consistency of the microwave communication device
[0003] At the same time, during the welding process between the cavity and the outer conductor, the solder flows around, which causes the heat of the solder to lose rapidly and affects the welding quality, and causes poor consistency and unsightly appearance due to the solder flowing around.

Abstract

The invention relate to a cable welding element. The cable welding element comprises a welding piece and a limitation structure, wherein the limitation structure is arranged in rear-end direction of the welding piece and forms an included angle with the welding piece, the welding piece is used for positioning a cable outer conductor and / or preventing soldering tin, and the limitation structure is used for positioning the cable outer conductor and / or preventing the soldering tin when a cable is placed in the limitation structure. The welding piece has the functions of preventing the soldering tin from downwards flowing along an outer wall so that a series of side effects are generated; and if a soldering tin drip is connected with a reflecting plate, the welding difficulty is high, and the cable is radially positioned, the limitation structure is used for axially positioning the cable, a dielectric layer of the cable is further ensured to successfully pass through, while the cable outer conductor is blocked, and a large amount of soldering tin can be prevented from axially flowing to cause short circuit.

Description

technical field [0001] The invention relates to a cable welding piece, a welding structure and a welding method. Background technique [0002] With the rapid development of wireless communication technology, the competition among communication industries has become very fierce, and the performance requirements of products are getting higher and higher. As a general-purpose cable in the communication industry, the welding quality of coaxial cables is directly related to the indicators of communication products. If the welding quality cannot be improved, it will be difficult to gain an advantage in the fierce competition. 'The common welding method is often to directly set a guide hole in the shell, and then directly weld the coaxial cable on the guide hole. However, in the existing microwave communication devices, there is no structure for fixing the cable on the cavity. The welding position between the cable and the cavity cannot be positioned accurately, which leads to poo...
