Spring needle module, filter and conducting and fixing method of filter and antenna coupling plate

Abstract

The invention relates to a spring needle module, a filter and a conducting and fixing method of the filter and an antenna coupling plate. The spring needle module comprises a needle tube, a medium, asilica gel spring, a lantern reed and a contact needle; a sufficient safety gap is reserved between the needle tube and the contact pin to prevent mutual conduction of the needle tube and the contactpin, the needle tube and the contact pin are connected by the lantern reed when a signal or current is conducted, the silica gel spring is further adopted, the silica gel has physiological inertia andbetter elasticity and extensibility, is not conducted to current and radio frequency signals thereby better ensuring the stability of the signal or a resistance value, and the problem that the filteris inconvenient to disassemble and assemble under the condition of poor contact or damage is solved; and the new spring needle module can effectively improve the transmission performance between thefilter and the antenna , thereby ensuring the stability of antenna signal transmission.

Description

technical field [0001] The invention relates to the technical field of communication filtering, in particular to a pogo pin assembly, a filter, and a conduction and fixing method with an antenna coupling plate. Background technique [0002] 5G large-scale antenna system architecture, including dense radiation array, power division network, coupling calibration network, blind mating connector and transceiver unit. The working principle of the entire 5G antenna system is that the radio frequency channel of the antenna (including unit modules composed of multiple radiation units) realizes the transmission and reception of wireless transmission signals; the transceiver unit realizes the transmission and reception of RF signals on the radio frequency channel; To monitor the transmit power and phase of each radio frequency channel; in this way, the system shaping algorithm realizes the precise 3-dimensional beam pattern of large-scale antennas by adjusting the amplitude and phase ...

Problems solved by technology

[0004] In the AFU antenna structure, the conduction and fixing method of the filter and the antenna coupling plate directly affects the stability of signal transmission and the performance of the antenna. The current metal cavity filter is generally conducted by welding the signal transmission pin (pin) with the antenna coupling plate. like Figure 7 As shown, it is fixed on the antenna coupling plate through the ground fillet welding on the cavity, and the welding method is inconvenient to disassemble, or, as Figure 8 Spring pins (pogo pins) are used to communicate with the coupling board, but the internal structure of the conventional pogo pin structure is reset by a metal spring, and the contact pin and the needle tube are in direct contact. The signal or current can be conducted through the spring or through the The conduction between the needle tube and the contact pin, the spring compression and the uneven contact of the needle tube will lead to the change of the resistance value, especially when the high-frequency radio frequency signal is particularly sensitive
