Radio frequency elastic contact structure used for welding-free interconnection

Abstract

The invention discloses a radio frequency elastic contact structure used for welding-free interconnection. The radio frequency elastic contact structure is inserted and matched with a PCB; electroplating through holes are formed in the PCB; the radio frequency elastic contact structure comprises a shell made from a copper-based alloy material; the shell is in direct contact with the electroplatingthough holes in the PCB; an insulating material medium body is arranged in the central position of the shell; the medium body is directly pressed into the shell through interference fit; a blind holeis formed in the central position of the interior of the medium body; an inner conductor is arranged in the blind hole; the inner conductor is an elastic contact part; and the shell, the medium bodyand the inner conductor form a radio frequency coaxial structure. According to the structure disclosed in the invention, the shell is equivalent to an outer conductor of the existing radio frequency connector, and the shell is directly inserted and matched with the electroplating through holes in the PCB, so that the mounting space requirement is lowered to the minimum, the weight is lowered, andredundant space mounting is not occupied, multiple times of lossless and welding-free interconnecting mounting and detaching can be realized, and convenience in detachment, post maintenance and replacement is achieved.

Description

Technical field [0001] The invention relates to a radio frequency elastic contact structure, in particular to a radio frequency elastic contact structure for solderless interconnection used for printed circuit board (PCB) signal transmission, and belongs to the technical field of electrical contact interconnection. Background technique [0002] The signal transmission of the printed circuit board (PCB board) has a variety of contact forms. Usually there are several plated through holes on the PCB board, and the signal transmission is carried out by contacting with 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 pins of the connector are directly matched with the plated through holes to realize system interconnection and signal transmission. [0003] For radio frequency connectors, such as the existing SMA, BNC, TNC and other series of radio frequency c...

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 multiple connectors are used together, not only may cause dimensional interference, but also The pulling force is very large, which cannot meet the actual needs of use

[0005] In addition, connecting pins can also be provided on the connector, and the connecting pins can be inserted into the plated through holes, or fixed together by soldering. Obviously, this connection method not only complicates the assembly process, but also cannot guarantee the stability of the assembly quality. The structure cannot be disassembled and cannot meet actual needs
