Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to an external plug used with a watertight wall-penetrating connector. Background Art

[0002] Electrical connectors are essential components for various electrical and electronic systems and are widely used in aerospace, aviation, nuclear industry, weapons, ships, electronics, transportation, computers, communications, healthcare, oil exploration, and other industries. As the "nerve hub and contact point" of the electrical signal transmission system, electrical connectors play a key role in bridging the transmission of electrical signals in the circuit. Their quality directly affects the performance and quality of the product. In actual use, connectors may need to be threaded through walls depending on the operating environment. After threading through the wall, the external plug often requires an external wiring harness. To improve the stability of the wiring harness connection and the threaded portion of the connector, as well as the stability of the wiring harness during use, the reliability of the connection between the external wiring harness and the connector, as well as the sealing stability, a watertight threaded connector with an external plug is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a watertight wall-penetrating connector equipped with an external plug, which is used to solve the problem of connection stability of the external wiring harness end after the connector penetrates the wall in the prior art.

[0004] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:

[0005] A watertight wall-penetrating connector equipped with an external plug, comprising:

[0006] A disc plug, wherein a socket is provided inside the disc plug, and the disc plug is located in the wall;

[0007] An external plug is arranged at one end of the disc plug, and a plug connecting seat is arranged between the external plug and the disc plug. The plug connecting seat is located at one end of the disc plug and extends into the interior of the disc plug, and the plug connecting seat is threadedly matched with the socket. A compression sleeve is threadedly connected to the outer wall of the disc plug connected to the external plug, and the compression sleeve extends to the outer wall of the external plug. A limiting ring is provided on the outer wall of the external plug, and the outer contour of the limiting ring slides with the inner wall of the compression sleeve.

[0008] To implement the above technical solution, the disc plug is used as a carrier of the wall-penetrating part, which can ensure the stability of the bearing capacity of the wiring harness. By arranging a plug connector between the external plug and the disc plug and threading the plug connector with the socket, the connection stability between the plug connector and the disc plug can be improved. By threading a compression sleeve on the outer wall of the end of the disc plug connected to the external plug, the compression sleeve is used to tighten the connection part of the disc plug and the external plug, thereby further improving the connection stability between the disc plug and the plug connector. The setting of the limit ring can limit the tightening of the compression sleeve when the compression sleeve tightens the external plug, thereby preventing the plug connector from being inserted too deeply.

[0009] In one embodiment of the present invention, an insertion guide groove is axially provided on the outer wall of the outer plug, and a guide block is provided on the inner wall of the disc plug. The guide block and the insertion guide groove are slidably engaged with each other. When the outer plug is inserted into the disc plug, the guide block and the insertion guide groove cooperate with each other to guide the insertion of the outer plug.

[0010] To implement the above technical solution, a sliding fit is provided between the guide block and the insertion guide groove. When the external plug is inserted into the disc plug, the guide block and the insertion guide groove cooperate with each other to guide the insertion of the external plug, thereby ensuring the stability of the plug connector inserted into the disc plug.

[0011] In one embodiment of the present invention, a sliding groove is provided at the rear end of the insertion guide groove along the radial direction of the outer plug, the guide block is slidably fitted with the sliding groove, and the size of the guide block is smaller than the size of the sliding groove.

[0012] The above technical solution is implemented by slidingly cooperating between the guide block and the slide groove, which can provide rotation space for the plug connector when it is rotatably connected to the disc plug, thereby avoiding the rotation restriction of the plug connector by the limit block.

[0013] In one embodiment of the present invention, a plug sealing groove is further provided on the outer wall of the outer plug at the rear side of the insertion guide groove, and a sealing gasket is provided in the plug sealing groove.

[0014] To implement the above technical solution, a plug sealing groove is provided on the outer wall of the outer plug at the rear side of the insertion guide groove, and a sealing gasket is used to ensure the sealing stability between the plug connector and the disc plug.

[0015] In one embodiment of the present invention, a plug limiting groove is provided on the front side of the limiting ring, and the base of the disc plug is embedded in the plug limiting groove.

[0016] To implement the above technical solution, a plug limiting groove is set at the root of the front side of the limiting ring. When the plug connector is assembled on the disc plug, the root of the disc plug is embedded in the plug limiting groove, which can limit the insertion depth of the plug connector and avoid the situation where the disc plug is damaged due to over-insertion.

[0017] In one embodiment of the present invention, the external plug is an arc-shaped plug, and an external connecting seat is provided between the external plug and the plug connecting seat. The external connecting seat is embedded in the plug connecting seat, and a locking nut is provided on the outer wall of the plug connecting seat at the embedded part.

[0018] To implement the above technical solution, by setting the external plug as an arc-shaped plug, it can serve as a limit for the connection of the wiring harness. By setting the external connecting seat between the external plug and the plug connecting seat, the connection stability between the external plug and the plug connecting seat can be ensured. The setting of the locking nut can facilitate the locking of the embedded part of the external connecting seat, thereby ensuring the connection stability between the external connecting seat and the plug connecting seat.

[0019] In one embodiment of the present invention, a plug flange is provided on the outer wall of the disc plug, a flange sealing groove is provided at the root of the plug flange, and a disc sealing groove is provided on the outer wall of the disc plug on the side of the plug flange close to the outer plug.

[0020] To implement the above technical solution, the setting of the plug flange can fix the plug on the wall. The root of the plug flange is provided with a flange sealing groove, which can ensure the sealing stability of the root of the plug flange. The setting of the disc sealing groove can ensure the sealing reliability of the disc plug embedded in the wall.

[0021] As described above, the utility model is a watertight wall-penetrating connector equipped with an external plug, which has the following beneficial effects: using the disc plug as a carrier of the wall-penetrating part can ensure the stability of the bearing capacity of the wiring harness; by arranging a plug connecting seat between the external plug and the disc plug, and threading the plug connecting seat with the socket, the connection stability of the plug connecting seat and the disc plug can be improved; by threading a compression sleeve on the outer wall of the end of the disc plug connected to the external plug, the compression sleeve is used to tighten the connection part of the disc plug and the external plug, thereby further improving the connection stability between the disc plug and the plug connecting seat; the setting of the limiting ring can limit the tightening of the compression sleeve when the compression sleeve tightens the external plug, thereby preventing the plug connecting seat from being inserted too deep.
