Problems solved by technology

The above technical solutions all improve the cable welding quality through technological methods, thereby improving the electrical performance of the cable assembly, but there is no guarantee that the connector will not experience the axial deviation of the cable and the fixed solder flow when welding the wire at the end of the connector. range, to avoid the problem of short circuiting the tail end of the electrical connector with solder

Embodiment 1

[0029] Such as figure 1 Shown is a structural schematic diagram of a high-performance method for realizing a tail-end welding electrical connector according to the present invention. The tail end of the electrical connector includes an outer conductor (2), a cable (3), a support body (7), and an inner conductor (6), the supporting body (7) plays the role of preventing axial deviation and fixing the solder flow range at the same time.

[0030] Such as figure 2 As shown, the outer conductor (2) is sequentially provided with the first inner cavity (21), the second inner cavity (22), the third inner cavity (23), the fourth inner cavity (24), and the fifth inner hole Cavity (25), the sixth inner hole cavity (26); the third inner hole cavity (23) is provided with a barb structure (231), and the third inner hole cavity (23) is used to assemble the dielectric body (5); the outer conductor ( 2) Set the first outer cylindrical surface (28), the second outer cylindrical surface (29), ...

Embodiment 2

[0039] Support body (7) also can not use, as Figure 9 In the figure above, the stripping structure of the cable design adopts this structure.

[0040] Such as Figure 8 As shown, an interference fit is set between the outer diameter of the fifth inner cavity (25) of the outer conductor and the outer diameter of the cable dielectric body (32), and the outer diameter of the sixth inner cavity (26) of the outer conductor and the outer diameter of the cable shielding layer (33) Clearance fit or interference fit.

[0041] Such as Figure 9 As shown, the cable (3) is first welded to the inner conductor (6) and then pressed Figure 8 Attached to the outer conductor for final tail soldering.

[0042] Both of the above two solutions are based on the same inventive concept, and both can achieve the same purpose, that is, to prevent the axial displacement, and at the same time fix the flow range of the solder to prevent the solder from short-circuiting the tail end of the electrical...

Abstract

A high-performance method for realizing a tail-end welding wire electrical connector, the tail end of the electrical connector includes an outer conductor (2), a cable (3), a support body (7), and an inner conductor (6), and is characterized in that : the support body (7) is provided with an outer cylindrical surface (71), and the first inner cavity (72) and the second inner cavity (73) are respectively arranged inside, and the inner diameter of the first inner cavity (72) of the support body is larger than that of the support The inner diameter of the second inner cavity (73) of the support body, the first inner cavity (72) of the support body and the cable shielding layer (33) are set to an interference fit or clearance fit, the second inner cavity (73) of the support body and the cable inner cavity The conductor (31) is interference fit, and the cylindrical surface (71) outside the support body is interference fit with the sixth inner cavity (26) of the outer conductor. According to the high-performance method of realizing the electrical connector with welding wire at the tail end of the present invention, the axial deviation can be prevented, and the flow range of solder can be fixed at the same time, so as to prevent the solder from short-circuiting the tail end of the electrical connector.

Description

technical field [0001] The invention relates to the technical field of radio frequency coaxial connectors, in particular to an electrical connector for welding wires at the tail end, which solves the axial deviation of the cable when welding the wires at the tail end of the electrical connector, and solves the problem of soldering the electrical connection when welding the wires. To solve the problem of short circuit of the device, realize the high performance of the tail welding wire electrical connector. Background technique [0002] At present, with the rapid development of the communication industry (3G / 4G / 5G), some RF coaxial connectors used in base station jumpers and feeder systems are in great demand, especially RF cable components are more and more widely used. What follows is that the performance requirements for RF coaxial connectors are getting higher and higher. [0003] There are many factors affecting the high performance of the cable assembly. In addition to...
