Abstract
The utility model belonging to the communication equipment technology relates to a multiple cores coaxial and signal cable plug used by the wireless base station equipment when the equipment transmits signals by radio or by the simulation intermediate frequency when simulation intermediate frequency transmits signals by intermediate frequency cable. The multiple cores coaxial and signal cable plug includes a shell, a inner cavity used to connecting wires is arranged in the shell, the rear end of the inner cavity is a wire inlet hole, the front end of the inner cavity is arranged with a front cover which is installed with a plurality of coaxial cable heads, in addition, the front cover is fixed with a signal plug. The utility model is compact in structure, reliable in running and can simplify the connection between the radio frequency subsystem out of the TD-SCDMA wireless base station and the indoor equipment.
Description
Technical field
The utility model belongs to the communication apparatus technology, relates to a kind ofly in 3G (Third Generation) Moblie TD-SCDMA base station system, and wireless base station device zooms out with radio frequency transmission or analog intermediate frequency zooms out employed multi-core coaxial and signal cable plug 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 structure 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 in the utility model is, a kind of compact conformation, reliable, the multi-core coaxial and the signal cable plug that can the outdoor Radio Frequency Subsystem in facilitating TD-SCDMA wireless base station be connected with indoor equipment are provided.
The utility model multi-core coaxial 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.The mating surface of protecgulum and housing is provided with sealing ring.
The utility model 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.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the end face structure schematic diagram of Fig. 1.
Embodiment
As showing of Fig. 1, has the inner chamber 2 that has to be used for carrying out wiring in the housing 1 of the present utility model, multicore coaxial cable and signal cable are entered by the incoming line 3 of intracavity posterior end, and are connected respectively with holding wire plug 6 with a plurality of coaxial electrical cable ends 5 on being installed in protecgulum 4.Single cored structure of the routine that each coaxial electrical cable end is made up of inner wire 51, insulator 52 and outer conductor 53.As shown in Figure 2, a plurality of coaxial electrical cable ends are " in-line " on protecgulum arranges, and the holding wire plug can adopt the plug of RS232 rs 232 serial interface signal connector.Protecgulum 4 is provided with sealing ring 7 with the mating surface of housing 1.
