Abstract

The invention discloses an assembly structure of a shaft body and a hole body and a connector. According to the assembly structure, the shaft body and the hole body are matched, and a clearance fit section and an interference fit section are included in an axial direction. A groove perpendicular to the axial direction is arranged in an outer surface of the shaft body and is located between the clearance fit section and the interference fit section. In the invention, a problem that an appearance, a structure and electrical performance indexes are influenced by burrs produced during interferencefit in an assembly process is solved. The invention further comprises a connector applying the structure. By the adoption of the assembly structure, a reject ratio and potential hazards of connectionand assembly can be reduced, and the electrical performance indexes of products are guaranteed.

Description

technical field [0001] The present application relates to the technical field of structural design, in particular to an assembly structure of a shaft body and a hole body and a connector using the structure. Background technique [0002] Interference fit is a very common assembly method used in the assembly process of the shaft body and the hole body. Especially in the assembly process of RF coaxial connectors, the main application is the assembly of the outer conductor and the assembly of the insulation support. [0003] When the outer conductor is assembled, if the brass hole and the brass shaft are assembled with an interference fit, burrs are likely to be stuck on the surface of the assembly, which has a great impact on the appearance, and the outer conductor of the connector is assembled with an interference fit , The burrs are stuck on the reference surface of the connector seat or inside the connector, which will seriously affect the electrical performance indicators...
