Problems solved by technology

Because the wall thickness of the connection between the second inner conductor and the first inner conductor is relatively thick, when the second inner conductor floats along the axial direction of the first inner conductor, the contact resistance between the second inner conductor and the first inner conductor is large, and the contact is not good. reliable

Embodiment 1

[0045] Such as Figure 1-5 As shown, it is a structural schematic diagram of an elastic inner conductor of a radio frequency coaxial connector provided by an embodiment. The elastic inner conductor of the radio frequency coaxial connector includes: an elastic conductor 100, a conductor 400, a pin shaft 200 and a spring 300 , the conductor 400 further includes a tailstock 420 and a round tube 410 .

[0046] Among them, such as Figure 4 As shown, the elastic conductor 100 is a circular cylindrical structure, and a first accommodating cavity 104 is disposed in the elastic conductor 100 . The elastic conductor 100 is made of elastic metal material through stamping, so the elastic conductor 100 has low processing cost, high processing efficiency, good quality consistency, and the thickness of the elastic conductor processed by stamping is thin.

[0047] The conductor 400 is arranged coaxially with the elastic conductor 100, and one end of the conductor 400 is slidably disposed i...

Embodiment 2

[0064] Such as Figure 7-9 As shown, it is a structural schematic diagram of an elastic inner conductor of a radio frequency coaxial connector provided in another embodiment. It can be seen from the figure that the elastic inner conductor of the radio frequency coaxial connector includes: an elastic conductor 100, a conductor 400, The pin shaft 200 and the spring 300. Wherein, the structure of the elastic conductor 100, the pin shaft 200 and the spring 300, the connection mode between the elastic conductor 100 and the pin shaft 200, and the connection mode between the spring 300 and the pin shaft 200 are all the same as those in Embodiment 1, and will not be described here. For the same content, please refer to the relevant description in Embodiment 1, and the difference is as follows.

[0065] The conductor 400 is an integral structure, the conductor 400 is provided with a second accommodation cavity 412, the spring 300 is placed in the second accommodation cavity 412, and t...

Abstract

The invention discloses an elastic inner conductor of a radio-frequency coaxial connector and a processing method thereof. The elastic inner conductor comprises an elastic conductor, a conductor and apin shaft, wherein the elastic conductor is of a cylindrical structure, and a first accommodating cavity is arranged in the elastic conductor; the conductor and the elastic conductor are coaxially arranged, one end of the conductor is arranged in the first accommodating cavity of the elastic conductor in a sliding mode, the inner surface of the elastic conductor and the outer surface of the conductor are in contact with each other, and a second accommodating cavity is arranged in the conductor; one end of the pin shaft is fixed in the first accommodating cavity of the elastic conductor, and the other end of the pin shaft is movably arranged in the second accommodating cavity; a spring is arranged in the second accommodating cavity, one end of the spring is connected with the pin shaft, and the other end of the spring is connected with the conductor. The elastic inner conductor disclosed by the invention can solve the axial fit tolerance between the radio-frequency coaxial connector and a circuit board and has the advantages of stable performance, convenient production and processing and low cost.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular, the invention relates to an elastic inner conductor of a radio frequency coaxial connector and a processing method thereof. Background technique [0002] The RF coaxial connector is a component that is attached to the cable or installed on the instrument, and is used as a component for the electrical connection or separation of the transmission line. In today's wireless communication base station applications, a large number of board-to-board RF coaxial connectors are required in the fourth generation (4G) and fifth generation (5G) wireless base stations. The inner and outer conductors of today's RF coaxial connectors use spring force to provide contact pressure between the connector and the circuit board, and use spring deformation to solve the axial fit tolerance between the connector and the circuit board. However, along with the deformation of the spring, the contact positi...
