Abstract

The invention discloses an improved cavity coupler. The improved cavity coupler comprises a housing and a cover plate, wherein the outer side walls of three side edges of the housing are respectivelyprovided with a first connector, a second connector and a third connector; a cavity is formed between the housing and the cover plate; a main conductor, a coupling conductor and an insulating supportassembly are arranged in the cavity; one end of the main conductor is connected with the first connector, and the other end of the main conductor is connected with the second connector; one end of thecoupling conductor is connected to the third connector, and the other end of the coupling conductor is connected to a resistor on the inner side wall of one side edge of the housing; the insulating support assembly comprises a support rod, a first insulating sleeve and a second insulating sleeve; the first insulating sleeve is connected to the inner side wall of one side edge of the housing through a support rod; the first insulating sleeve sleeves the outer circumference of the main conductor; the second insulating sleeve is connected to the inner side wall of the other side edge of the housing through the other support rod; and the second insulating sleeve sleeves the outer circumference of the coupling conductor. The improved cavity coupler has the advantages of endurance of the insulating support device.

Description

technical field [0001] The invention relates to communication electronic components, in particular to an improved cavity coupler. Background technique [0002] The cavity coupler is used to distribute wired radio frequency signals according to the requirements. It has the characteristics of wide operating frequency, small insertion loss in the band, high isolation, small standing wave ratio, and beautiful appearance. The coupler cavities on the existing market are similar, and the insulating strip in the improved cavity coupler is simply placed in the housing without any fixing measures, which is easy to shift and affects the quality of signal transmission. Existing couplers use insulating support strips pasted on the bottom wall of the coupler housing as insulating support devices to support the main conductor and coupling conductors. After a long period of use, the insulating support strips are easy to fall off, that is, the durability of the insulating support devices is ...
