Embodiment 1

[0022] Embodiment one: see Figure 1~5 As shown, a high-tolerance board-to-board radio frequency coaxial contactor includes two PCBs and a radio frequency coaxial contactor 02. The radio frequency coaxial contactor 02 consists of a metal base 021, an insulating medium body 022 and five The metal elastic needle forms a single-piece structure, which eliminates the two-piece or three-piece structure of SMB and SMP, which can effectively reduce the cost and complexity of use. The metal base 021 uses copper as the base material.

[0023] Such as Figure 4 As shown, the metal elastic needle is composed of a metal base 022c, a coil spring 022b, and a metal contact shell 022a. The inside of the metal base 022c is hollow, and the coil spring 022b and the bottom end of the metal contact shell 022a are fixed on Inside the metal base 022c, the port of the metal base 022c uses the closing process, so that the coil spring 022b and the metal contact shell 022a are fixed in the metal outlet ...

Abstract

The invention discloses a high-tolerance board-to-board RF coaxial contactor comprising two PCBs and a RF coaxial contactor and characterized in that: the RF coaxial contactor consists of a one-piecestructure formed by a metal base, an insulating dielectric body and five metal elastic needles. The high-tolerance board-to-board RF coaxial contactor eliminates SMB and SMP two-piece or three-piece structures, can reduce use cost and use complexity, uses a coil spring structure as a main body to perform pressure contact, ensures signal transmission, high axial tolerance and high radial tolerance.

Description

technical field [0001] The invention relates to a coaxial contactor, in particular to a board-to-board radio frequency coaxial contactor with high tolerance. Background technique [0002] With the rapid development of communication technology, the integration of modules is getting higher and higher, and the application of board-to-board RF coaxial connectors in the interconnection of wireless system modules is becoming more and more extensive. The board-to-board coaxial connector is mainly used for the connection and transmission of radio frequency information between printed circuit boards. In the actual application process, it has changed from using one connector to using multiple connectors or arrays. During the production process, PCB manufacturing, surface mount technology, assembly and design tolerances cause axial, radial and angular errors between board-to-board components, so board-to-board RF signal connection and transmission require high tolerance connectors for...
