RF connector protection device and base station antenna

Abstract

Embodiments of the present invention relate to the technical field of base station antennas, and disclose a radio frequency connector protection device and a base station antenna. The radio frequency connector protection device includes: a connector protector connected to the installation surface of the radio frequency connector, and a reflector is located between the connector protector and the radio frequency connector. Between the mounting surfaces of the connector, the connector protector has a first surface and a second surface opposite to each other; a boss is extended on the first surface, and an assembly hole matching the boss is opened on the reflector. A mounting hole arranged through the first surface and the second surface is opened inside; a cable channel arranged through the first surface and the second surface is extended and formed on the second surface. In the RF connector protection device of the embodiment of the present invention, compared with the conventional RF connector, the RF connector omits the flange, which reduces the cost of forming the RF connector, and at the same time, the threaded hole is added in the opposite direction, which is convenient for fixing; The boss passes through the corresponding position of the reflector to isolate the contact between the fastening screw and the reflector and reduce the influence of intermodulation.

Description

technical field [0001] The present invention relates to the technical field of base station antennas, and in particular, to a radio frequency connector protection device and a base station antenna. Background technique [0002] With the continuous development of communication technology, more requirements are put forward for antenna products, especially the requirements for frequency bands and intermodulation values ​​are getting higher and higher. Traditional base station antenna designs do not have third-order requirements or have lower third-order requirements. However, with the development of the communication network, the requirements for the third order of the antenna are getting higher and higher. [0003] In the prior art, the base station antenna radio frequency joint assembly structure includes a reflector, a radio frequency joint, a fastening screw and a rivet nut. When assembling, the reflector first needs to prefabricate rivet nuts on the corresponding holes, ...
