Active antenna waterproof radio-frequency connector for ship

Abstract

Disclosed is an active antenna waterproof radio-frequency connector for a ship. The active antenna waterproof radio-frequency connector comprises a base (11), a first insulator (3) and a contact (1). The active antenna waterproof radio-frequency connector is characterized in that the boss end of the first insulator (3) is inserted into a mounting hole of the base (11), the end face, provided with a boss, of the first insulator (3) abuts against the surface of the base (11), the rod portion of the contact (1) penetrates through a through hole in the first insulator (3) to extend into the base (11), the part, located in the base (11), of the rod portion of the contact (1) is sequentially sleeved with a second insulator (6) and a nut (8), the nut (8) is used for fixing the part, located in the base (11), of the rod portion of the base (11), and a welding terminal (9) is fixed to the end face of the part, located in the base (11), of the rod portion of the contact (1); the other end of the contact (1) is provided with an inner screw hole (20) which is connected with an inner screw of an antenna (14) and external threads (16) which are matched with internal threads (15) on a nut cap (17) for fixing the antenna (14). The active antenna waterproof radio-frequency connector for the ship can be widely applied to waterproof electric connection of various outdoor electronic products, and meanwhile, small distribution electric parameters of contact grounding are kept.

Description

technical field [0001] The invention relates to an electronic communication technology, in particular to an active antenna radio frequency connector, in particular to a marine active antenna waterproof radio frequency connector. Background technique [0002] At present, in the communication receiving system, the use of active antenna is a common means to improve the sensitivity of the receiver, which requires both the amplifier (an important part of the active antenna) and the antenna rod to work outdoors, which requires the enclosure of the amplifier There must be good sealing characteristics, and in order to make the radio signal induced on the antenna mast be transmitted to the input end of the amplifier without loss, it is required to have a waterproof wall-through RF connector at the end of the antenna mast and the input end of the amplifier . It should satisfy both good radio frequency transmission characteristics and good sealing and waterproof properties, and the ...
