Problems solved by technology

This structure obviously increases the cost of use. More importantly, the existing installation space is already very narrow, and it is impossible to install the adapter; in addition, when the RF coaxial structure is matched with the PCB board, due to the clamping direction between the force direction and the PCB board Angle, easy to lead to unreliable connection, unable to meet the actual use needs

Embodiment Construction

[0020] The content of the present invention will be described below in conjunction with specific embodiments.

[0021] like Figure 1~Figure 4 As shown, the radio frequency coaxial structure of the present invention is used for vertical interconnection with the PCB board 50 without soldering. One end of the matching surface is called the inner conductor rear end 11, the end of the inner conductor 10 close to the mating surface of the RF coaxial structure and the PCB board 50 is called the inner conductor front end 13, and the middle position of the inner conductor 10 is the inner conductor elastic body 12, The inner conductor rear end 11, the inner conductor elastic body 12, and the inner conductor front end 13 form a complete inner conductor 10, and the inner conductor 10 is provided with a tapered step 14 to prevent detachment, such as image 3 shown.

[0022] The radio frequency coaxial structure of the present invention includes a dielectric body 20 of insulating materia...

Abstract

The present invention discloses a radio frequency coaxial structure for realizing solderless vertical connection with a PCB. The radio frequency coaxial structure comprises an inner conductor, a dielectric body made of an insulating material and a main outer conductor made of a copper-based alloy material. The inner conductor is pressed into the dielectric body through interference fit, the main outer conductor is arranged outside the dielectric body, and the dielectric body is pressed into the main outer conductor through interference fit. The radio frequency coaxial structure comprises a positioning outer conductor. An outer conductor elastomer is arranged at the middle of the positioning outer conductor, and the main outer conductor is pressed into the positioning outer conductor through interference fit and is in direct contact with the outer conductor elastomer. According to the radio frequency coaxial structure, an existing radio frequency coaxial structure is directly installedon the PCB without switching, the weight is reduced, and no excessive installation space is occupied. The vertical installation of the radio frequency coaxial structure on the PCB is ensured by the positioning outer conductor. In addition, the requirement of the installation space is reduced to a minimum, multiple times of non-destructive solderless interconnection installation and disassembly canbe realized, the loading and unloading are convenient, the subsequent maintenance and replacement are convenient, and the requirements of actual use are satisfied.

Description

technical field [0001] The invention relates to a radio frequency coaxial structure, in particular to a radio frequency coaxial structure used for solder-free vertical interconnection of printed circuit boards (PCB boards), belonging to the technical field of electrical contact interconnection. Background technique [0002] There are many contact forms for the signal transmission of the printed circuit board (PCB board). Usually, there are several plated through holes on the PCB board, and the signal transmission is carried out by contacting the external circuit through the external through holes. Generally, this connection structure is suitable for direct plugging and unplugging of the connector, that is, the contact pin of the connector is directly matched with the plated through hole to realize system interconnection and signal transmission. [0003] For RF connectors, such as the existing SMA, BNC, TNC and other series of RF connectors, its structure is a RF coaxial stru...
