Description

Sealing device for wall-penetrating sealing of cable with plug

Technical Field

The utility model relates to a sealing device for wall-through sealing of a cable with a plug.

Background

The traditional sealing structure of through-wall of the cable with plug has two kinds, one is to utilize the sealing assembly of through-wall, the cable does not weld the plug first, weld the plug on site after sealing through-wall, the disadvantage of this mode is that the cable plug welding of optic fibre, video, audio frequency, etc. needs professional equipment, the on-the-spot implementation is inconvenient, must weld the plug again when maintaining or dismantling. This approach presents a number of inconveniences in practical applications.

In another mode, a wall through socket is arranged, the cable welding plugs at two ends are in butt joint with the wall through socket, the mode is high in cost, the wall through thickness is not more than 6.5mm, the limitation is large, the sealing structure is unreliable, the watertight performance of the wall through socket and the plug is limited, the cable is required to be separated from the welding plugs when passing through the wall, the connecting point is increased, the resistance of the cable assembly is increased, the possible fault point is increased, and the cable performance and the reliability are reduced.

In practical application, many products are provided with cables with plastic-sealed number plugs, are not detachable and can not be welded on site, and particularly, the conditions of optical fibers, image and signal cables are more, so that great difficulty exists in wall-penetrating sealing.

Disclosure of Invention

In order to solve the technical problems, the sealing device for the through-wall sealing of the cable with the plug is simple in structure and low in cost, ensures the internal and external communication of the cable car, and can ensure the water tightness of the through-wall.

The technical scheme adopted by the utility model is as follows: a sealing device for through-wall sealing of a cable with a plug comprises an outlet seat, a sealing gasket, a round pad and a round cover; the wire outlet seat is of a tubular structure with external threads, a sealing gasket and a round gasket are arranged in an inner hole of the wire outlet seat, the sealing gasket is of an annular structure, the sealing gasket is provided with a radial seam, and the round gasket is provided with a U-shaped groove; the dome is in threaded connection with the wire outlet seat; the top of the round cover is provided with a wire outlet hole.

In the sealing device for the through-wall sealing of the cable with the plug, the circular pad is positioned between the circular cover and the sealing pad.

In the sealing device for the through-wall sealing of the cable with the plug, the sealing gasket is made of rubber, and the round gasket is made of metal.

In the sealing device for through-wall sealing of the cable with the plug, the central hole of the wire outlet seat is conical towards the end of the dome, and gradually reduces along with the distance from the dome; the middle part of the sealing gasket is a conical structure matched with the conical part of the central hole of the wire outlet seat; both ends of the sealing gasket are of cylindrical structures.

In the sealing device for through-wall sealing of the cable with the plug, the top of the dome is provided with the square boss.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model has simple structure and low manufacturing cost, can make different specification models according to different cables, is convenient to mount and dismount, can be repeatedly used, does not influence the performance of the cable with the plug, can be widely used for the cable wall-through design of various devices, can replace the design of arranging wall-through sockets, field welding plugs and the like according to the needs, reduces cable connection points and reduces the cost.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1-4, the utility model comprises a wire outlet seat 1, a sealing gasket 2, a round pad 3 and a round cover 4. The wire outlet seat 1 is of a tubular structure with external threads, a sealing gasket 2 and a round gasket 3 are arranged in an inner hole of the wire outlet seat, the sealing gasket 2 is of an annular structure, the sealing gasket is provided with a radial slit 21, and the round gasket 3 is provided with a U-shaped groove; the dome 4 is in threaded connection with the wire outlet seat. The sealing gasket 2 is made of rubber, and the round gasket 3 is made of metal; the circular pad 3 is located between the circular cap 4 and the sealing pad 2. The top of the dome 4 is provided with a square boss 41, which is convenient for the fastening operation of a spanner. The center of the top of the dome 4 is provided with a wire outlet hole 42.

The center hole of the wire outlet seat 1 is conical towards the end of the dome 4, and the diameter gradually decreases along with the distance from the dome 4. The middle part of the sealing gasket 2 is a conical structure matched with the conical part of the central hole of the wire outlet seat; both ends of the sealing gasket 2 are of cylindrical structures.

When the cable outlet seat 1 is used, the cable outlet seat 1 is a metal welding piece, the wall penetrating plate 5 is provided with a through hole at the position where the cable is required to penetrate through the wall, the size of the through hole meets the maximum outer diameter of the cable with the plug, the trafficability of the cable is ensured, the cable outlet seat 1 is welded at the position where the wall penetrating plate is provided with the through hole, and the cable outlet seat 1 is concentric with the wall penetrating plate. The cable 6 sequentially passes through the through hole on the wall penetrating plate 5, the central hole of the wire outlet seat 1 and the wire outlet hole 42 of the circular cover 4, the radial slit 21 of the sealing gasket 2 is broken off to be clamped on the cable 6, the circular cover 3 is clamped on the cable 6 through the U-shaped groove 31, finally the circular cover 4 is screwed by a wrench, and the circular cover 4 is connected and fastened with the external thread of the wire outlet seat 1 through the internal thread of the circular cover 4. The round cover 4 compresses the sealing gasket 2 in the central hole of the wire outlet seat 1 through the round gasket 3 to realize sealing.
