Description

A wire-passing sealing and locking device

technical field

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

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.

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 frequently, which usually requires the assistance of external tools, which takes a long time and greatly reduces the test efficiency.

After searching the authorized patents, the cable sealing device is the main one among the similar devices, which has a complex structure and fixed usage mode, which is not suitable for repeated disassembly and assembly, and has no locking function.

Contents of the invention

The purpose of the present invention is to solve the problem of loose cables and poor sealing performance in the cable hole of the closed test box, and provide a cable-passing sealing and locking device, which can realize rapid sealing of the cable hole of the test box and fastening of cables, and can be used for various Environmental test chambers are used.

The technical solution adopted by the present invention to solve the above problems: the wire passing sealing and locking device includes a wire passing stud 1, a sealing ring I2, a sealing ring II3, a thin nut 4, a tapered split ring 5, and a wire passing cover nut 6; The stud 1 passes through the sealing ring I2, the box wall 8, the sealing ring II3 and the thin nut 4 in turn, and the thin nut 4 is threaded with the threaded stud 1; the tapered split ring 5 is placed on the threaded stud 1 In the inner groove, the cable 7 passes through the wire-passing stud 1, the tapered split ring 5, and the wire-passing cover nut 6 in sequence, and the wire-passing cover nut 6 is threadedly connected with the wire-passing stud 1.

The tapered split ring 5 of the present invention is made of copper, nylon or tetrafluoroethylene, and its inner diameter and opening size can be changed by external force, which is more conducive to the tight fit of the cable and the device, and has better sealing and locking effects.

The front end of the tapered split ring 5 of the present invention is conical, and the rear end is cylindrical. This structural design is mainly due to the fact that the force is greater and the compression is tighter during the compression process.

The groove at one end of the thread passing stud 1 of the present invention is conical. Such a design is mainly adapted to the structure of the tapered split ring 5 .

The tapered surface of the tapered split ring 5 of the present invention is in close contact with the internal tapered surface of the groove of the wire passing stud 1 to achieve the sealing and locking effect of the present invention.

Beneficial effects of the present invention: the present invention has simple structure, few parts, and can be quickly installed and disassembled; the cable 7 is compressed by the closure of the tapered split ring 5 to prevent it from loosening; the wire cover nut 6 is tightened and the tapered split ring 5 The tight fit with the inner tapered surface of the groove of the wire passing stud 1 has a sealing effect on the test chamber. After testing, the sealing effect is 100%. Therefore, the present invention effectively solves the problems of locking the cable connecting the airtight test box and external equipment and sealing the test box.

Detailed ways

The technical solutions of the present invention will be further clearly and completely described below in conjunction with the accompanying drawings and embodiments.

Examples of the described embodiments are shown in the drawings, wherein like or similar reference numerals designate like or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

Example 1

Fig. 1 is a schematic diagram of an embodiment of a wire-passing sealing and locking device of the present invention.

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.

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 calculation. Among them, the angle of the conical surface of the tapered split ring 5 after compression (closed opening) is not less than the angle of the conical surface in the groove of the thread-passing stud 1; the thread-passing stud 1, the tapered split ring 5 and the thread-passing cover nut 6 The size of the wire hole is matched with the tolerance of the diameter of the cable 7 .

As shown in Figure 1, the wire-passing stud 1 passes through the sealing ring I2, the box wall 8, and the sealing ring II3 in turn, and the thin nut 4 is close to the sealing ring II3, and is threaded and fastened with the wire-passing stud 1; the tapered split ring 5 Put it in along the tapered surface of the groove of the thread-passing stud 1; the cable 7 passes through the thread-passing stud 1, the tapered split ring 5, the thread-passing cap nut 6 in sequence, the thread-passing cap nut 6 and the thread-passing stud 1 Threaded connection, manually tighten the cable cover nut 6, push the tapered split ring 5 to make its opening smaller and inner hole diameter smaller, and lock the cable 7 so that it does not loosen.

The effect achieved by the embodiment: it can be installed quickly, and the cable can be fastened to avoid loosening of the cable, which will affect the test; it has a sealing effect on the 8 openings of the test box wall, preventing the external environment from affecting the test of the tested product in the test box conditions, leading to inaccurate test results.

The above description is only a preferred example of the present invention, and is not intended to limit the present invention. Any modifications, equivalent replacements and simple improvements made on the essence of the present invention should be included within the protection scope of the present invention. .
