Abstract
The utility model belongs to the communication equipment technology, relating to a multi-core coaxial and signal cable plug shell and cable connection structure, which comprises a section of tubular adapter connected with the shell of the coaxial cable plug. The tubular adapter is formed by a pair of fixed half ring and active half ring cooperating with each other, wherein, the fixed half ring is connected with the shell and the active half ring is connected with the fixed half ring by the connecting bolt. One section of the multi-core coaxial cable is held between the fixed half ring and the active half ring; the front half section of the section of the multi-core coaxial has no protective sleeve layer, and an exposed cable shielding layer contacts with the fixed half ring and the front half section with comparatively small inside diameter of the active half ring. While the inner wall of the rear half section of the fixed half ring and the active half ring is provided with tooth spaces, and the part opened with the tooth spaces is tightly connected with the cable protective sleeve layer. The utility model can not only bear comparatively large axial power, but has advantages of simple structure and easy installation.
Description
Technical field
The utility model 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 housing and cable connection structure 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 multi-core coaxial and signal cable structure, this structure is combined in many single core coaxial cables and signal cable in the thicker sheath, again its multi-core coaxial and signal cable plug with special use is connected, 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.In this structure, should guarantee that the terminal on each single core coaxial cable and the plug casing reliably electrically contacts, guarantee simultaneously convenient rapid and reliable firm connection the between housing and the whole cable again, be convenient to on-the-spot installation.And traditional be used for the structure that single core coaxial cable is connected with connector, and its structure is complicated on the one hand, and inconvenience is installed, and on the other hand, its axial relay that can bear is less, can't be applicable to being connected between multicore coaxial cable and the cable plug housing.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and can bear bigger axial tension and reliably be connected with the shielding of multicore cable with housing, and multi-core coaxial simple in structure, easy for installation and signal cable plug housing and cable connection structure.
Multi-core coaxial of the present utility model and signal cable plug housing comprise one section tubular configured joint that is connected with the housing of coaxial cable plug with cable connection structure, this tubular configured joint constitutes whole tubular structure by a pair of stationary half that cooperatively interacts and movable semi-ring, stationary half and housing are connected as a single entity, and movable semi-ring is pressed connection by attachment screw mutually with stationary half; One section of multicore coaxial cable is clamped between stationary half and the movable semi-ring, preceding half section no restrictive coating of this section cable, the cable shield that is exposed and stationary half and the less preceding half section reliable press contacts mutually of movable semi-ring internal diameter, and having teeth groove on the second half section inwall of stationary half and movable semi-ring, this section has the part of teeth groove and the tight interlock of restrictive coating of cable.Also can have preceding teeth groove on the preceding half section inwall of described movable semi-ring, to increase its tensile strength.
The utility model is finished being connected and fixed of cable and cable plug housing owing to being connected with the direct screw of movable semi-ring by stationary half, installation process is simple, convenient, save parts too much in the traditional structure and loaded down with trivial details installation steps, reduced manufacturing cost and construction intensity; Simultaneously, the ability of carrying axial tension has been improved greatly by the tight interlock of rubber sheath layer of teeth groove and cable in its coupling part.

Fig. 2 is a vertical section structure schematic diagram of the present utility model;
Fig. 3 is the cross-sectional view of movable semi-ring.
Embodiment
As shown in the figure, in the structure of the present utility model, stationary half 1 holds together with the housing 3 of cable plug, and movable semi-ring 2 is connected by screw 4 with stationary half 1, and one section cable 5 is clamped between movable semi-ring and the stationary half.Preceding half section internal diameter of stationary half and movable semi-ring is less, contacts teeth groove 6 before also having on the preceding half section inwall of movable semi-ring with the screen 51 of cable; The restrictive coating 52 tight interlocks of then passing through teeth groove 7 and cable of stationary half and movable semi-ring second half section.
Claims (3)
