Low-intermodulation compatible type connection radio frequency socket and plug and operation method thereof

Abstract

The invention provides a low-intermodulation compatible type connection radio frequency socket and plug. The socket comprises an outer socket conductor, an inner jack conductor, a socket insulating support, an end face reed and a radial reed. The outer socket conductor is internally provided with an annular groove matched with and coupled to an outer plug conductor. The inner side of the annular groove is the front-segment tongue diameter, and the end face of the annular groove is a mechanical benchmark face. The front-segment tongue diameter and the mechanical benchmark face are designed to be of an integrated structure. The inner plug conductor in the plug is internally provided with an annular groove matched with and coupled to the outer socket conductor and an unlocking sleeve. The inner side of the annular groove is matched with the outer side of a socket-shaped groove in the radial direction, the satisfactory axial matching length is set, and the bottom of the annular groove is the mechanical benchmark face. According to the low-intermodulation compatible type connection radio frequency socket and plug, improvement is conducted on the mechanical benchmark face and electrical benchmark face separating design and contact outer conductor slotting design in the prior art, continuity of full-spectrum characteristic impedance and electric connectivity of a contact port are guaranteed, intermodulation interference and reflection coefficients are further lowered, and wider working bands and excellent return losses are achieved.

AI Technical Summary

Problems solved by technology

[0008] 1) The important intermodulation index and return loss index of mobile communication have not yet met the requirements of the excellent level of modern complete communication equipment;

[0009] 2) Due to the side contact of the outer conductor, the existence of the axial gap of the outer conductor is recognized, resulting in a reduction of the proper radio frequency bandwidth;

[0010] 3) The insertion and unlocking are not comfortable, nor can it adapt to applications in environments with large vibrations;

[0011] 4) Plugs and sockets of the same specification or similar specifications cannot be compatible for connection;

[0012] 5) The quick-insert self-locking mechanism requires a corresponding card slot, and due to the existence of manufacturing tolerances, it is inevitable to leave a gap when inserting; that is, the locking with gears is caused, which is also the main cause of axial movement or falling off;

[0013] 6) Since the contact head needs separate design, processing and assembly, the manufacturing cost is increased and the manufacturing accuracy is also affected
