[0003] At present, there are a series of different forms of inter-board connection mechanisms on the market. Conventional inter-board mechanisms mostly use inter-board three-piece sets to achieve inter-board floating interconnection, which is achieved by two solder plate connectors and a floating adapter rod. However, this interconnection method requires a relatively high distance between boards, and there is still room for optimization in space utilization. For this reason, low-profile RF connector structures will have huge market potential. Summary of the invention

[0011] Furthermore, the lower end cover, the elastic deformation structure and the upper end cover together constitute the outer conductor of the radio frequency connector.

[0012] Furthermore, the inner conductor is a multi-bend highly elastic structure, which is used for the self-adaptive function of the axial spacing of the inner conductor.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Example 1

[0023] like Figure 1-Figure 3 As shown, a floating radio frequency connector is disclosed, including a lower end cover 1, an elastic deformation structure, a dielectric body 3, an upper end cover 4 and an inner conductor 5;

[0024] The dielectric body 3 is arranged at the center of the elastic deformation structure, the inner conductor 5 is arranged in the dielectric body 3, one end of the elastic deformation structure is connected to the lower end cover 1, and the other end is connected to the upper end cover 4; the inner conductor 5 adopts an elastically deformable structure to provide axial floating amount to achieve real-time contact between the two ends; the inner cavity structure of the dielectric body 3 is adjusted according to the structure of the inner conductor 5 to provide positioning and guiding functions for the inner conductor 5;

[0025] The outer conductor is composed of a lower end cover 1, a wave spring 2 and an upper end cover 4, wherein the wave spring adopts an elastically deformable structure to provide axial floating amount, realize real-time conduction of the upper and lower end covers, realize the function of the outer conductor of the RF connector, and realize the floating function at the same time.

[0026] The inner conductor adopts an elastically deformable structure to ensure real-time contact between the two ends; the inner cavity structure of the dielectric body can be adjusted according to the structure of the inner conductor to provide positioning and guiding functions for the inner conductor.

[0027] The outer conductor is composed of upper and lower end caps and a wave spring. The upper and lower end caps are arranged on the upper and lower end surfaces of the wave spring to ensure that the wave spring is stable in force deformation and double-end contact. The wave spring adopts an elastically deformable structure to provide axial deformation to realize the floating function of the outer conductor. Both the inner conductor and the outer conductor have elastic deformation and lossless recovery functions, which together realize the axial spacing self-adaptation function of the connector.

[0028] The present invention is a connector adapted to low height and vibrating or floating environments. The floating property of the inner and outer conductors satisfies the board spacing requirements and environmental requirements. The lower end cover 1 and the upper end cover 4 are provided with positioning grooves matching the PCB panel.

[0029] See also Figure 1 , Figure 2 , Figure 3 The present invention has high working reliability and good stability. Since the working pressure of the connector is required to be no less than a certain value, there will be no discontinuity between the working state and the pressure, so it has a high-reliability electrical connection.

[0030] Example 2

[0031] A floating radio frequency connector is disclosed, comprising a lower end cover 1, a wave spring piece 2, a dielectric body 3, an upper end cover 4 and an inner conductor 5; the dielectric body 3 is composed of a dielectric body 1 31 and a dielectric body 2 32. When connected to a board, the lower end cover 1 is welded to the board, and the upper end cover 4 is in direct contact with the board. The upper end cover 4 of the connector is floating at one end to realize the function of adaptive spacing between connector boards. The six parts together realize high-quality transmission of radio frequency electromagnetic field signals. The upper end cover 1, the wave spring piece 2 and the lower end cover 6 constitute an outer conductor;

[0032] The inner conductor 5 adopts a multi-bend high-elastic structure, which can achieve large elastic deformation and lossless recovery, realize the self-adaptive function of the axial spacing of the inner conductor, and at the same time ensure the stability of the contact between the upper and lower ends.

[0033] The inner cavity structures of the dielectric body 1 31 and the dielectric body 2 32 are designed according to the structure of the inner conductor 5 , and the inner conductor 5 is positioned and fixed by single-end clamping.

[0034] The wave spring 2 adopts a curved design and can restore without loss under a certain elastic deformation, thereby ensuring its reliability when elastic deformation occurs and realizing the axial spacing self-adaptation function of the outer conductor.

[0035] The present invention meets the requirements of board spacing and environmental requirements through the adaptability of the axial spacing between the inner and outer conductors. The positioning grooves are designed on the upper and lower PCB panels to match the upper and lower end covers of the connector, and then a certain pressure is applied to ensure the reliability of the connection and complete the electrical signal connection between the boards.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
