Insulation protection device for fixing RF communication passive device

Abstract

The present invention provides an insulation protection device for a fixed RF communication passive device. The insulation protection device comprises a slider, an insulating sheath 1, an insulating sheath 2, a micro air pump, an air pipeline, an annular groove and a damping airbag. The slider is fixed to an annular side surface of the insulating sheath 2. The insulating sheath 1 is installed at the right end face middle part in a plastic shell. The adjustment function of an insulation protection range is realized by the design, water and dirt at the surface of a line can be removed, the micro air pump is fixed at the upper end face middle part of the plastic shell, an upper end of the air pipeline is connected to the micro air pump, a lower end of the air pipeline is connected to the damping airbag, the annular groove is arranged at the annular side face middle position in a wire hole, and the damping airbag is assembled in the annular groove. According to the above design, damping and sealing functions are realized, the service life of the line is prolonged, the sealing of the insulation protection device is improved, and the insulation protection device has the advantages of a reasonable structure, good insulation and protection performance, a long service life, good stability and high reliability.

Description

technical field [0001] The invention relates to an insulation protection device for fixing radio frequency communication passive components, belonging to the technical field of communication. Background technique [0002] RF passive devices are mainly used in the construction of base stations of wireless communication systems and indoor distribution systems. Especially in the indoor distribution and coverage of wireless signals in buildings, there are many kinds of applications and a huge number. RF passive devices play the role of connecting or distributing RF signals in base station construction and indoor distribution projects. The performance parameters of RF passive devices mainly include operating frequency band, insertion loss, input and output standing waves, port isolation, in-band fluctuation, band external suppression, intermodulation products, and power handling. [0003] The insulation protection device in the prior art has a simple structure, limited protecti...
