Description
Technical field
The utility model relates to a kind of cable penetrating sealing configuration, is specifically related to a kind ofly adapt to that the more cable of quantity crossing cabin under elevated pressures is installed, the penetrating cable rubber sealing structure of reusable, easy accessibility.
Background technique
In plenum chamber model test, sensor in air cavity chamber wall and chamber need to be connected to the collector in sealing plate opposite side sealed compartment through sealing plate, corresponding penetrating cable sealing configuration should be set on sealing plate, to meet the air cavity seal request of the highest 0.3Mpa, avoid the measuring system equipment such as collector to bear high pressure or meet water short circuit after air cavity water inlet.
Compared with pre-stage test, the measuring point quantity of large-scale model product significantly increases, there are 102 drive test points all to need through front air cavity sealing plate, 26 drive test points need to be through rear air cavity sealing plate, and according to structure collectivity scheme, on rear air cavity sealing plate, two collectors will be installed, the space that can be used for sensor cable crossing cabin is very limited.In addition, as investigation test, test period and funds are all subject to strict restriction, and between each of mock bomb time, state of the art changes frequently, and this penetrating cable sealing configuration should be able to adapt to repeatedly the needs of fast assembling-disassembling.
In multiple industrial fields such as Aeronautics and Astronautics, boats and ships and electric power, often relate to cable or pipe by the sealing problem of through hole.The field lower at sealing load or reliability requirement is not high, can adopt the mode of encapsulating to seal, and this seal form can adapt to the requirement of multi-cable sealing, structure efficiency is higher, but its complex process, packing are longer curing time, and cable is changed, dismounting inconvenience, and maintenance is poor; The seal form that elastomer adds nut under high pressure seals reliably, but install time cable be through nut, after plug need to being cut off again weld, in the situation that number of cables is more, brought difficulty to sealing configuration installation, dismounting and maintenance.
Therefore, need to design a kind of high density penetrating cable sealing configuration, to improve structure efficiency, and simplify the operation, shorten technology setup time.
Model utility content
Technical problem to be solved in the utility model is: for overcoming the deficiencies in the prior art, provide a kind of and adapted to that the more cable of quantity crossing cabin under elevated pressures is installed, the high efficiency sealing configuration of reusable, easy accessibility.
Technical solution of the present utility model is: a kind of penetrating cable rubber sealing structure, comprise sealing plate, rubber plate, comb shape backing plate, cover plate and screw, rubber plate is the plate structure of interarea rectangular band fillet, cross section wedge shape, and the size of rubber plate is greater than the wedge shape section square hole size on sealing plate; Rubber plate thickness is greater than sealing plate, offers the hole for placing sensor cable along the long symmetrical line of rubber plate, and perforate aperture is not more than cable size, and rubber plate is divided into upper and lower two parts along long symmetrical line; The comb shape backing plate of guaranteeing that cover plate pressure evenly applies is installed between rubber plate and cover plate, and cover plate provides compressive force by screw fastening for rubber plate.
The quantity of perforate is in 100.
Cover plate has four, sealing plate each two of both sides.
The beneficial effects of the utility model: the utility model provides guarantee for shortening experimental technique setup time, and its technological scheme is functional, and operation, easy to maintenance, has effectively saved test period and funds.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is installation diagram of the present utility model;
Fig. 3 is schematic diagram before compression of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, 2, 3, a kind of penetrating cable rubber sealing structure, comprise sealing plate 1, rubber plate 2, comb shape backing plate 4, cover plate 3 and screw 5, rubber plate 2 is the plate structure of interarea rectangular band fillet, cross section wedge shape, and the size of rubber plate 2 is slightly larger than the wedge shape section square hole size on sealing plate 1; Rubber plate 2 thickness are slightly larger than sealing plate 1, offer the hole for placing sensor cable along the long symmetrical line of rubber plate 2, and perforate aperture is not more than cable size, the quantity of perforate 100 with, interior rubber plate 2 is divided into upper and lower two parts along long symmetrical line; The comb shape backing plate 4 of guaranteeing that cover plate pressure evenly applies is installed between rubber plate 2 and cover plate 3, and cover plate 3 cover plates have four, sealing plate each two of both sides, provide compressive force by screw fastening for rubber plate 2.
Concrete installation process is: taking cable need to through sealing plate 1 as matrix, on sealing plate 1, be processed with the band fillet square hole of wedge shape section, cable is placed on by root in half hole of any rubber plate 2, two blocks of rubber plates 2 of fastening, put into the square hole of sealing plate 1, comb shape backing plate 4 and cover plate 3 are installed successively, are tightened the sealing function that can realize penetrating cable sealing configuration after cover plate 3 with screw 5.
The unexposed technology of the utility model belongs to general knowledge as well known to those skilled in the art.
