Abstract
The utility model belongs to the communication equipment technology, relating to a coaxial cable plug with a plurality of cores, which comprises a shell. A cavity is arranged in the shell and is used for connecting wires; the rear end of the cavity is a wire inlet, and the front end of the cavity is connected with a front cover which is provided with a plurality of installing holes lined in a transversal line shape, and each installing hole is provided with a coaxial cable head, the middle of which is fixed with a crossette. The front cover positions the crossette from the front side of the crossette, the rear side of which is provided with a plate which is opened with a plurality of U- shaped notches which have the same space with the installing holes, and cooperates with a plurality of coaxial cable heads splice through the U-shaped notch in radial direction, and then positions the crossette from the rear side of the crossette. The utility model has advantages of compact structure and reliable running, moreover, simplifies the outdoor radio frequency sub system of the TD-SC DMA wireless base station and the indoor device connection.
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 multicore coaxial 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, cost costliness of zooming out.For addressing the above problem, at present existing a kind of multicore coaxial cable structure, this structure is combined in many single core coaxial cables in the thicker sheath, thereby Radio Frequency Subsystem that can the TD-SCDMA wireless base station is outdoor is reduced to one group with the cable that indoor equipment is connected, and has simplified cable wiring manufacture.But when the multi-core coaxial of this structure and signal cable equipment connect, if adopt a plurality of traditional single-core plug structures to install, its installation process is still complicated, and it is bigger to take up room, 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, the multicore coaxial cable plug that provides a kind of compact conformation, reliable, can the facilitating TD-SCDMA wireless base station outdoor Radio Frequency Subsystem and indoor equipment reliably to be connected.
Multicore coaxial cable plug of the present utility model includes a housing, is provided with the inner chamber that is used for carrying out wiring in housing, and the rear end of inner chamber is an incoming line, and the front end of inner chamber is connected with a protecgulum; Be " in-line " on the protecgulum and be placed with a plurality of installing holes, be interspersed with a coaxial electrical cable end of forming by inner wire, insulator and outer conductor in each installing hole; The middle part of coaxial electrical cable end is provided with crossette, and protecgulum positions it from the front side of crossette; The rear side of crossette has a slice baffle plate, has a plurality of spacings " U-shaped " notch suitable with above-mentioned installing hole spacing on the baffle plate, and baffle plate cooperates by radially pegging graft with a plurality of coaxial electrical cable ends by " U-shaped " notch, and from the rear side of above-mentioned crossette it is positioned; The rear side of described baffle plate is by the location of the step in the housing.Can be provided with sealing ring on the mating surface of protecgulum and housing.
The utility model is owing to be installed on the housing a plurality of coaxial electrical cable ends are integrated, and 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, and conveniently install at the scene that can solve, and greatly reduces construction intensity.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the enlarged diagram of Fig. 1 standard coaxial cable head location structure;
Fig. 3 is the end face structure schematic diagram of Fig. 1;
Fig. 4 is the B cross-sectional view 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.During use, multicore coaxial cable is entered by the incoming line 3 of intracavity posterior end, and is connected respectively with a plurality of coaxial electrical cable ends 5 on being installed in protecgulum 4.A plurality of coaxial electrical cable ends pass the installing hole 41 on the protecgulum and are " in-line " and arrange (as shown in Figure 2).Protecgulum 4 is provided with sealing ring 7 with the mating surface of housing 1.
As shown in Figure 3, single cored structure of the routine formed by inner wire 51, insulator 52 and outer conductor 53 of each coaxial electrical cable end.Cable end carries out axial location by the crossette 54 at its middle part, that is, the front side of crossette is stopped that by protecgulum 4 rear side of crossette is stopped by a baffle plate 6 that then the rear side of baffle plate 6 then carries out axial location by the step in the housing 11.
As shown in Figure 4, baffle plate cooperates by radially pegging graft with coaxial electrical cable end 5 by a plurality of " U-shaped " notch 61.
Claims (2)
