Abstract
The invention pertains to a communications device technology and relates to a multi-chip coaxial signal cable plug and a socket thereof. The plug comprises a shell in which a cavity is arranged for wiring. The back of the cavity is an incoming line pore and the front of the cavity is provided with a front cover having a plurality of coaxial cable heads comprising internal conductors, insulators and external conductors. In addition, the front cover is provided with plugs of a signal wire. The socket comprises a seat body with a vertical plug-board. On the plug-board, a plurality of single-core coaxial cable heads comprising central conductors, insulators and external conductors are arranged in the shape of horizontal line. Jacks at the front and back of the single-core coaxial cable heads are respectively positioned on the front and back sides of the plug-broad fixedly provided with a double-pass joint of the signal wire. The invention presents compact structure and reliable operation and can simplify the connection between a radio frequency subsystem outside a TD-SCDMA wireless base station and indoor equipment.
Description
Technical field
The invention belongs to the communication apparatus technology, relate to a kind ofly in 3G (Third Generation) Moblie TD-SCDMA base station system, wireless base station device zooms out with radio frequency transmission or analog intermediate frequency zooms out employed multi-core coaxial and signal cable plug and socket with immediate frequency cable.
Background technology
Existing coaxial cable is generally single cored structure, and its structure is followed successively by center conductor, insulating barrier, screen and restrictive coating from the inside to the outside.In traditional mobile communication system wireless base station device, the outdoor equipment of base station has only been installed power amplifier/LNA module, add the Radio Frequency Subsystem that control module is formed the base station with the individual power amplifier in 4 (or 6)/LNA module, be pulled to the indoor equipment of base station with radio frequency cable.This scheme of zooming out exists distance short (less than 60m), the problems such as cable many (reaching 30 or 21), addressing, installation inconvenience of zooming out.For addressing the above problem, at present existing a kind of multi-core coaxial and signal cable structure, this structure is combined in many single core coaxial cables and signal cable in the thicker sheath, thereby the cable that Radio Frequency Subsystem that can the TD-SCDMA wireless base station is outdoor is connected with indoor equipment is reduced to one group that is equivalent to original outside diameter of cable by original 21-30 root, simplify cable wiring manufacture, effectively reduced cost.But when the multi-core coaxial of this structure and signal cable equipment connect, if adopting traditional single-core plug and socket installs, its installation process is still complicated, and a plurality of single-core plugs and signaling interface connect respectively, it takes up room bigger, can't carry out waterproof and bonding, influence the reliability service of equipment.
Summary of the invention
Technical problem to be solved by this invention is, a kind of compact conformation, reliable, the multi-core coaxial and signal cable plug and the socket that can the outdoor Radio Frequency Subsystem in facilitating TD-SCDMA wireless base station be connected with indoor equipment are provided.
Multi-core coaxial of the present invention and signal cable plug include a housing, in housing, be provided with the inner chamber that is used for carrying out wiring, the rear end of inner chamber is an entrance hole, the front end of inner chamber is provided with protecgulum, a plurality of coaxial electrical cable ends of being made up of inner wire, insulator and outer conductor are installed on the described protecgulum, in addition, on protecgulum, also be fixed with the holding wire plug.A plurality of single core coaxial cable connection-pegs are " in-line " and are arranged on the plugboard.The mating surface of protecgulum and housing is provided with sealing ring.
Multi-core coaxial of the present invention and signal cable socket include a pedestal that has vertical plugboard, be " in-line " on the plugboard and be placed with a plurality of single core coaxial cable connection-pegs of forming by center conductor, insulator and outer conductor, the socket at the forward and backward two ends of single core coaxial cable connection-peg lays respectively at the forward and backward both sides of plugboard, also is installed with the holding wire duplex fitting on the described plugboard.In addition, the front and rear end of pedestal is provided with sealing ring.
Plug of the present invention is because with a plurality of coaxial electrical cable ends and the holding wire plug is integrated is installed in the housing chamber, the shared inner chamber of their terminals makes when it is simple in structure, compact, also is easy to realize water-tight and electromagnetic shielding more; When particularly zooming out construction in the TD-SCDMA wireless base station, this structure can be used with multi-core coaxial and signal cable, is convenient to on-the-spot the installation, greatly reduces the difficulty of bringing in cost and the construction, has guaranteed the reliability service between Radio Frequency Subsystem and the equipment.In addition, socket of the present invention is with a plurality of single core coaxial cable connection-pegs and the signal wire connecting head is integrated is installed on the pedestal, not only make it simple in structure, compact, and, in the head end box of TD-SCDMA 3G wireless base station and the installation in the base station machine room equipment, this structure can be used with multi-core coaxial and signal cable plug, has improved the outstanding effect that the new technology employing is produced in the 3G communication equipment.
