example 1

[0021] figure 1 It is a schematic diagram of an embodiment of a wire-passing sealing and locking device of the present invention.

[0022] In the figure, the thread-passing stud 1, the thin nut 4, and the thread-passing cover nut 6 are made of copper, the sealing ring I2 and the sealing ring II3 are made of silicon rubber, and the tapered split ring 5 is made of tetrafluoroethylene.

[0023] Assuming that the tested product in the airtight test box is connected with the controller outside the box by a cable, the cable needs to be sealed and locked through the 8 openings of the box wall to prevent the external environment from affecting the test conditions in the box, and the invention is installed at the 8 openings of the box wall The device, according to the diameter of the opening of the box wall 8, is processed into a thread-passing stud 1, a sealing ring I2, a sealing ring II3, a thin nut 4, a tapered split ring 5 and a thread-passing cover nut 6 through tolerance calculat...

Abstract

The invention relates to a wire passing sealing locking device. The wire passing sealing locking device comprises a wire passing stud, a sealing ring, a thin nut, a conical opening ring and a wire passing cover type nut. The wire passing stud sequentially penetrates through the sealing ring and the box wall, the wire passing cover type nut is used for sealing and fastening the wire passing stud through the sealing ring, a cable passes through the wire passing stud, the conical opening ring and the wire passing cover type nut, the wire passing cover type nut is fastened, the cable can be effectively fixed, and the cable and the wire passing stud are sealed by matching with the conical opening ring. According to the wire passing sealing locking device, the structure is simple, the installation is convenient, the sealing performance is good, and the phenomenon that the cable is not loosened and the box wall is free of gas (or liquid) leakage is ensured.

Description

technical field [0001] The invention relates to a line passing sealing and locking device, which belongs to the field of test equipment and is used for sealing and locking the line passing through the wall of a closed test box. Background technique [0002] The tested product is usually connected to the control equipment outside the box through cables to achieve the purposes of power supply, communication, monitoring, control, etc. The current test equipment usually has a wire hole on the box wall, which is circular in shape. To prevent the impact of the external environment, the hole is usually filled with cloth or wood blocks after the cable is passed. The sealing effect is poor, and the cable is not easy to fix. Especially when the cable is shaken, the stuffing is likely to fall off. [0003] The cable requirements of different tested products are different, such as quantity, diameter, etc. When carrying out different tests, the cables need to be replaced and fastened fre...
