Abstract
The utility model provides a pyrocondensation pipe that antenna cable seal structure is equipped with the tubulose outlet that is become by two semi -circular structure amalgamations in butt joint department of antenna upper cover plate and lower plate, and still be equipped with one and be used for the cover in the cable outside and place the tubulose in and be qualified for the next round of competitions intraoral elasticity seal cover and one and be used for the cover in the tubulose outlet outside the size of the internal diameter of elasticity seal cover and external diameter makes its set can expand owing to the supporting of cable after on the cable to because the extrusion of tubulose outlet and contracting after putting into the tubulose outlet, with keep with the laminating of cable surface and tubulose outlet internal surface, the size of pyrocondensation pipe makes it can wrap up the tubulose outlet after receiving the thermal contraction to produce the restraining force that the centering tightened up to it. Be interference fit between elasticity seal cover and cable and the tubulose outlet, realized good sealing. And setting up of pyrocondensation pipe makes its installation of being convenient for very much.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, specifically the hermetically-sealed construction at cable outlet place in a kind of antenna structure.
Background technology
Due to the requirement of degree of protection, existing antenna structure except sealing, also requires that cable outlet mouth has sealing to design except realizing between base and cover plate.The general employing of this place sealing at present smears liquid-state silicon gel form.Consider that antenna needs debugging even to reprocess, this method causes removes inconvenient, and not easy-clear after silica gel solidification, affects sealing again.Meanwhile, consumption smeared by silica gel and operation is not easily held, and easily causes sealing poor, even affect aesthetic property.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned defect, provides a kind of good airproof performance, and easy-disassembling-assembling antenna cable hermetically-sealed construction.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of antenna cable hermetically-sealed construction, the tubulose line outlet pieced together by two semicircular structures is provided with at the joint of antenna upper cover plate and lower shoe, also be provided with one for be enclosed within outside cable and the elastic seal cartridge be placed in tubulose line outlet and one for being enclosed within the heat-shrink tube outside tubulose line outlet, the internal diameter of described elastic seal cartridge and the size of external diameter make it be enclosed within after on cable can to expand due to the supporting of cable, and shrink due to the extruding of tubulose line outlet after putting into tubulose line outlet, to keep the laminating with cable outer surface and tubulose line outlet inner surface, the size of described heat-shrink tube makes it can wrap up tubulose line outlet after heat shrinkable, and the restraining force of tightening up to center is produced to it.
The outer circumference surface of described elastic seal cartridge is provided with annular boss, and the inner surface of tubulose line outlet is provided with detent corresponding with it.
The inner surface of described tubulose line outlet is provided with the burr of profile of tooth.
The beneficial effects of the utility model are: this hermetically-sealed construction forms the semicircular structure of tubulose line outlet the part of flexible for cable joint-box sealing shroud being put into, and compress piece together tubulose line outlet after, be interference fit between elastic seal cartridge and cable and tubulose line outlet, achieve good sealing.And the setting of heat-shrink tube makes it be convenient to very much install, after the upper cover plate of antenna and lower shoe installation being fixed, the heat hot draw makes it shrink.Only need during dismounting to destroy heat-shrink tube, there is not the residue problem of silica gel sealing.

Embodiment
Illustrate frame mode of the present utility model by reference to the accompanying drawings.
As shown in Figure 1, hermetically-sealed construction of the present utility model, except the tubulose line outlet 6 of upper cover plate 1 and lower shoe 2 joint, also comprises heat-shrink tube 3 and elastic seal cartridge 5.In Fig. 1, the state of tubulose line outlet 6 in non-split, comprises two semicircular structures laid respectively on upper cover plate 1 and lower shoe 2.Elastic seal cartridge 5 is made up of rubber, silica gel elastomeric material, enables it be out of shape when being subject to external force.The internal diameter of this elastic seal cartridge 5 is more smaller than the external diameter of cable 4, enables it be enclosed within the outer rear flank of cable 4 and expands due to the supporting of cable, forms interference fit.And the external diameter of elastic seal cartridge 5 is more bigger than the internal diameter of the tubulose line outlet 6 after split, make it put into tubulose line outlet 6, and can shrink due to the extruding of tubulose line outlet after tubulose line outlet 6 split, form interference fit equally.Heat-shrink tube 3 for fixing tubulose line outlet 6 further, and forms the restraining force of tightening up to center to it.Heat-shrink tube 3 shown in Fig. 2 is the state of not yet heat shrink, the semicircular structure forming tubulose line outlet 6 is put in the part of cable 4 being overlapped flexible sealing shroud 5, and be connected and fixed upper cover plate 1 and lower shoe 2 by the screw etc. in antenna original structure, make semicircular structure compress piece together tubulose line outlet 6 after, heat-shrink tube 3 to be enclosed within tubulose line outlet 6 and heating makes it shrink the constraint that can be formed tubulose line outlet 6, and to complete installation.
In order to improve sealing further, the inner surface of tubulose line outlet 6 can arrange the burr of profile of tooth, when tubulose line outlet 6 extrudes elastic seal cartridge 5, the surface of elastic seal cartridge 5 produces and is out of shape and embeds between adjacent profile of tooth burr, thus forms more efficiently sealing.Location conveniently between elastic seal cartridge 5 and tubulose line outlet 6, can arrange annular boss 8 on the outer circumference surface of elastic seal cartridge 5, and the inner surface of tubulose line outlet 6 is provided with detent corresponding with it.Can predict, annular boss 8 be arranged and is the inner surface of tubulose line outlet 6, and detent is arranged at elastic seal cartridge 5 outer circumference surface and also there is effects equivalent.
