Plate fixing pin, antenna reflector plate and antenna

Abstract

The invention provides a plate fixing pin, an antenna reflector plate and an antenna. The plate fixing pin is used for realizing mutual fixing between plates, and comprises an inserting column, a front blocking part, a rear blocking part and limiting protrusions arranged on the periphery of the inserting column, wherein the front blocking part and the rear blocking part are correspondingly connected to the front and rear ends of the inserting column in the inserting direction. The plate fixing pin is arranged on a through hole preformed in a plate in a penetrating mode, the front and rear blocking part correspondingly abut against the opposite two end faces of the two plates on the outermost side, and the limiting protrusions correspondingly abut against the opposite end faces of adjacenttwo plates along the end faces of two ends in the inserting direction. While the mutual fixed connection between plates is realized, the plate fixing pin can avoid the direct contact between the adjacent two plates and maintain the spacing between the plates through the limiting protrusions.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a board fixing pin, an antenna reflector and an antenna using the board fixing pin. Background technique [0002] The base station antenna is composed of a reflector, a feed network, and a radiation unit, which involves the connection of a large number of metal parts, including the connection between the reflectors, the connection between the reflector and the metal debugging parts, and so on. In the prior art, for the antenna reflector composed of two-layer board connection, or the connection between the end plate, the side plate and the bottom plate in the antenna reflector, the fixed connection between the plates is usually directly fastened by screws. Although it has high strength, due to factors such as the limitation of processing technology and the potential difference of materials, the surface current density at the contact surface is relatively large, and the elect...

Problems solved by technology

In the prior art, for the antenna reflector composed of two-layer board connection, or the connection between the end plate, the side plate and the bottom plate in the antenna reflector, the fixed connection between the plates is usually directly fastened by screws. Although it has high strength, due to the limitations of the processing technology and the potential difference of the material, the surface current density at the contact surface is relatively large, and the electrical performance index of the antenna is greatly affected, and the intermodulation index is unstable.
