Abstract

The utility model discloses a kind of coaxial cable connecting device, including middle body and two fixed plate bodies, the two ends of the middle body are respectively equipped with connection boss, provided with the cable aperture for accommodating coaxial cable in the intermediate sleeve body, described cable aperture runs through two connection boss of middle body, the middle part of the fixed plate body is provided with being connected the positioning hole that boss is coordinated, and is detachably connected between the fixed plate body and middle body.The utility model aims to provide a kind of coaxial cable connecting device that can be stably connected with two coaxial cables.

Description

A kind of coaxial cable connecting device
Technical field
The utility model belongs to cable connection field, more particularly to a kind of coaxial cable connecting device.
Background technology
In the prior art, coaxial cable docking is typically to be combined and constituted by left and right joint and middle pin connector part, Such as China Patent Publication No.:CN104241906A, discloses a kind of connector for radio-frequency coaxial cable, connector for radio-frequency coaxial cable Including outer conductor, inner wire and insulator, wherein, above-mentioned outer conductor for tubular structure, step ring is provided with its central through hole Face;Above-mentioned insulator loads in the central through hole of above-mentioned outer conductor, and the step anchor ring being adjacent in outer conductor through hole, insulator Middle part is provided with through hole;Above-mentioned inner wire is stretched into the central through hole of outer conductor through the through hole in the middle part of insulator.Although it is real Existing coaxial cable docking, but need the erection joint on two coaxial cables, in addition it is also necessary to coordinate intermediate connector to realize Connection, its installation process is relatively complicated, and coaxial cable is released contact not by external force effect generation when often because of arrangement circuit Good or open circuit, connection reliability is poor, has a strong impact on signal transmission.
In order to improve connection reliability, also A designer person is proposed the coaxial cable at two ends directly fixed connection side Formula, such as China Patent Publication No.:CN204706698U, discloses a kind of coaxial cable banjo fixing butt jointing, is connected by sleeve pipe, pipe Set, cored wire binding post, left and right shielding line extruding taper ring, left and right waterproof extruding fixing seal cushion rubber, left and right nut are constituted, The copper core of coaxial cable is stretched into be fixedly connected in cored wire binding post by screw in compression, and shielding line extruding taper ring in left and right exists Coordinate respectively with the tubaeform conical surface port of pipe adapter sleeve left and right ends in swivel nut endoporus and fix the shielding line of coaxial cable, Left and right waterproof extruding fixing seal cushion rubber elastic deformation is held left and right coaxial cable tightly sealing respectively and fixed, while by swivel nut endoporus Left and right end is sealed.However, such banjo fixing butt jointing requires higher for the size of coaxial cable, and the reliability being connected It is poor.
Utility model content
The utility model is to overcome above-mentioned deficiency of the prior art can be steady by two coaxial cables there is provided one kind Surely the coaxial cable connecting device connected.
To achieve these goals, the utility model uses following technical scheme:
A kind of coaxial cable connecting device, including middle body and two fixed plate bodies, the two ends point of the middle body It She You not connect provided with the cable aperture for accommodating coaxial cable in boss, the intermediate sleeve body, described cable aperture runs through intermediate sleeve Two connection boss of body, the middle part of the fixed plate body is provided with being connected the positioning hole that boss is coordinated, the fixed plate It is detachably connected between body and middle body.Middle body is set in outside coaxial cable to be connected, the interior lines of coaxial cable Core is docked, so as to be fixed with attachment means between the outer core insertion fixed plate and connection boss of coaxial cable, this When coaxial cable the junction of interior core be located in the cable aperture of middle body.Therefore, the attachment means of this programme can will be same The inside and outside core of shaft cable is fixed, and improves connection reliability.
Preferably, the connection boss is provided with the male cone (strobilus masculinus) coaxially arranged with cable aperture, the diameter of the male cone (strobilus masculinus) Outwards it is gradually reduced by middle body, the side wall of the positioning hole is provided with the inner conical surface coordinated with male cone (strobilus masculinus).
Preferably, the taper of the male cone (strobilus masculinus) is less than or equal to the taper of inner conical surface.
Preferably, described fixed plate body is provided with some mounting holes around positioning hole, the middle body is even Connect and bolt hole corresponding with mounting hole is provided with around boss, mode connects for screw between the fixed plate body and middle connection.
The beneficial effects of the utility model are:(1)Using this attachment means by two shorter coaxial cables of length again Connection, substantially increases the availability of coaxial cable;(2)The stable connection of coaxial cable is reliable, can effectively prevent two coaxially Loosened between cable.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is mounting structure schematic diagram of the present utility model.
In figure:Middle body 1, connects boss 1a, cable aperture 1b, male cone (strobilus masculinus) 101, fixed plate body 2, inner conical surface 201, positioning Hole 202, screw 3, coaxial cable 4, outer core 4a, copper connecting tube 5, heat-shrink tube 6, tack insulating tape 7, waterproof sealing layer 8, PVC tape 9.
Embodiment
The utility model is further described with reference to the accompanying drawings and detailed description.
In embodiment as shown in Figure 1, a kind of coaxial cable connecting device, including middle body 1 and two fixed plate bodies 2, the two ends of middle body are respectively equipped with connection boss 1a, intermediate sleeve body provided with the cable aperture 1b for accommodating coaxial cable, cable Two connection boss of middle body are run through in hole, and connection boss is provided with the male cone (strobilus masculinus) 101 coaxially arranged with cable aperture, male cone (strobilus masculinus) Diameter be outwards gradually reduced by middle body.The middle part of fixed plate body is provided with being connected the positioning hole 202 that boss is coordinated, It is detachably connected between fixed plate body and middle body, the side wall of positioning hole is provided with the inner conical surface 201 coordinated with male cone (strobilus masculinus), outer cone The taper in face is less than or equal to the taper of inner conical surface.Fixed plate body is provided with four mounting holes around positioning hole, and middle body exists Connect and bolt hole corresponding with mounting hole is provided with around boss, screw 3 is connected between fixed plate body and middle connection.
During actual installation, as shown in Fig. 2 by after two alignments of coaxial cable 4 to be connected, two ends sawing is put down Whole, core in one section is exposed in the end of coaxial cable.Copper connecting tube 5 is inserted in interior core afterwards, by regulation crimping so as to by two The interior core at end is attached, with the wrapped copper connecting tube of tack insulating tape 7, and with the cladding tack insulating tape of PVC tape 9.
