Embodiment Construction
[0023] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0024] Such as figure 1 Shown is a schematic diagram of the inventive high temperature and high sealing cable. It can be seen from the figure that the high temperature and high sealing cable consists of five parts: sealing flange 1, sealing colloid 2, sealing tape 3, cable 4 and end cap 9.
[0025] 1 First wrap the sealing tape 3 on the cable 4, so that multiple bundles of cables are fixed into one bundle, and a cable bundle with a certain diameter is formed.
[0026] 2 Clamp a bundle of cables in step 1 into the hollow sealant 2 that is split into two halves, the sealant 2 is tapered in shape;
[0027] 3 Clamp the flange 1 that has been split into two halves to the tapered sealant 2 that is equipped with cables in step 2, and the middle section 7 of the flange is semi-cylindrical, with a conical cavity 8 in the middle, which can be compared with that in step 2....

The invention relates to a detachable recycled temperature altitude cable sealing device and an assembly method. The sealing device comprises a sealing flange, sealing colloid, a sealing tape, a hoopand an end cover, wherein the sealing flange is provided with a conical inner cavity which penetrates along the left-right direction and can be split into two halves; multiple cables are sealed through the sealing tape and then pressed through two halves of sealing colloid; the sealing colloid is pressed through two halves of sealing flanges; and one end of the left end and the right end of the sealing flange is provided with a mating hole of a temperature altitude box and the other end is fastened through the hoop and the end cover. Through the detachable mode of splitting the sealing flangeand the sealing colloid into two halves to be pressed, so that the cable sealing device can be recycled, information exchange between a test specimen and testing equipment in the temperature altitudetest process is achieved, the method is simple and easy to operate, good in sealing effect and reliable in connection, resources are saved and the test efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of environmental testing, and relates to a detachable and recyclable high-temperature and high-temperature cable sealing device and an assembly method. Background technique [0002] When the temperature and altitude test chamber is doing the air pressure test, it is often necessary to energize the inside of the test chamber or connect external testing equipment. At this time, it is necessary to solve the sealing problem of the cable connected to the test chamber; Sealing issues for sub-atmospheric pressure crossing lines. Most of the traditional methods are sealed by media such as plasticine or wood boards, which cannot achieve a good sealing effect. [0003] The currently existing cables using flange potting also have their disadvantages. Each set of cables needs to be potted separately, and the potted cables are no longer suitable for other tests, which increases the cost of cable production and potting. ...
