Reed type low-board-spacing elastic radio frequency connector

Abstract

The invention relates to a reed type low-board-spacing elastic radio frequency connector which comprises an outer conductor, an inner conductor and an insulator. The outer conductor comprises a first outer shell, the upper end and the lower end of the first outer shell are respectively provided with a second outer shell, the second outer shells can elastically float along the axial direction relative to the first outer shell, and the insulator is arranged in the first outer shell; the inner conductor comprises a first reed and a second reed which are arranged in a central symmetry mode, the first reed comprises a first elastic piece part and a first installation part which are connected, and the second reed comprises a second elastic piece part and a second installation part which are connected; the first elastic piece part is provided with an upper contact point which is in elastic contact with the upper printed board and a first side contact point which is in elastic contact with the second installation part; and the second elastic piece part is provided with a lower contact point which is in elastic contact with the lower printed board and a second side contact point which is in elastic contact with the first installation part. The space between the printed boards can be reduced, transmission of high-speed radio-frequency signals is facilitated, and the forming difficulty and the assembling difficulty of the inner conductor and the insulator are reduced.

Description

technical field [0001] The invention belongs to the technical field of radio frequency connectors, in particular to a reed type elastic radio frequency connector with low board spacing. Background technique [0002] Inter-board RF connectors are used between two printed boards that need to be interconnected to realize RF signal transmission between printed boards. The traditional RF connector includes an outer conductor and an inner conductor coaxially installed in the outer conductor. The inner conductor adopts a pin, and the pin can be axially floating. A jack that matches the pin is provided on the printed board. After quasi-mating, the vertical connection between the boards is realized. The floating pin generally uses elastic elements to realize the axial floating function, resulting in a larger axial dimension of the connector, and an increase in the board spacing of the printed board. Therefore, the axial length of this kind of radio frequency connector that cooperate...

Problems solved by technology

The traditional RF connector includes an outer conductor and an inner conductor coaxially installed in the outer conductor. The inner conductor adopts a pin, and the pin can be axially floating. A jack that matches the pin is provided on the printed board. After quasi-mating, the vertical connection between the boards is realized. The floating pin generally uses elastic elements to realize the axial floating function, resulting in a large axial dimension of the connector, and the board spacing of the printed board increases accordingly.

Therefore, the axial length of this type of RF connector, which cooperates with pins and jacks to realize vertical interconnection between boards, is relatively large, which cannot meet the application scenarios of low board spacing
