The shield cover is equipped with four mounting grooves, the top of mounting groove is equipped with the pinhole that supplies the contact pin to pass.

The debugging apron with still be equipped with shielding paper between the mainboard, be equipped with on the shielding paper and lap corresponding pinhole with the debugging, the spring needle pass the pinhole with mainboard connection.

A plurality of U-shaped through grooves are formed in the debugging cover plate side by side.

The invention has the beneficial effects that: the mounting groove is formed in the shielding cover and serves as a cavity of the filter, and the resonant piece of the filter is mounted in the mounting groove, so that the filter and the shielding cover form an integrated structure, the height of the small base station is reduced, the manufacturing cost is reduced, and meanwhile, the problems of positioning and mounting of the filter are solved; the contact pins at the input end of the filter are welded with the antenna plate, the four groups of filter contact pins can stably fix the antenna plate, and the height of the welding spot can be controlled in a shorter range, so that the height can be further reduced by about 1mm compared with a long support and a screw head in the prior art, and the problem of installation and fixation of the antenna plate and the problem of antenna signal conduction are solved by welding the antenna plate and the filter contact pins; the output end of the filter is connected with the main board by adopting a spring pin structure, so that the structure can be quickly disassembled and assembled.
