Abstract

The invention discloses a high frequency head-used rubber core assembling structure, which comprises a shell, an upper cover, a rubber cylinder, a needle core and a reed, wherein the shell is internally provided with a first cavity for accommodating the upper cover and the rubber cylinder and a second cavity for enabling the needle core to pass through; the first cavity and the second cavity are communicated; the upper cover and the shell are in interference fit; and the needle core and the upper cover are in interference fit. Through interference fit between the upper cover and the shell andinterference fit between the needle core and the upper cover, sealing and waterproofing of the rubber core assembling structure can be realized, and the assembling is simple.

Description

technical field [0001] The present invention relates to the technical field of high-frequency head, and more particularly relates to a rubber core assembly structure for high-frequency head. Background technique [0002] Satellite TV low-noise down-converter, also known as high-frequency head, is composed of band-pass filter, high-frequency amplifier, mixer, local oscillator and intermediate frequency amplifier. The function of the high frequency head is to receive satellite TV signals, and perform channel selection, signal amplification and frequency reduction processing, and finally output a stable intermediate frequency signal. [0003] Since the tuner is installed outdoors, the environment is complex, such as rainy and foggy weather or weather with high humidity. If the tuner is damp or flooded, performance failures such as signal reception and amplification capability degradation will occur. In order to improve the waterproof performance and assembly problems of the tu...
