A sealed socket with a novel bent structure

Abstract

This utility model discloses a sealing socket with a novel bent structure, including a plug assembly and an elbow assembly. The elbow assembly includes an integral elbow and an elbow nut. One end of the integral elbow is mounted on one side of the plug assembly and connected by the elbow nut. This utility model provides a first bend that bends outward at the end of the integral elbow. A stepped surface is provided on the corresponding end of the plug assembly, forming a second bend that mates with the first bend. The end of the first bend abuts against the stepped surface, forming a sealing groove with the second bend. A sealing ring is provided in the sealing groove, effectively preventing gaps in the seal caused by improper installation of the integral elbow during insertion, which would affect the sealing performance between the integral elbow and the plug housing.

Description

Technical Field

[0001] This utility model belongs to the field of connector plug technology, specifically relating to a sealed socket with a novel bent structure. Background Technology

[0002] Electrical connectors are a commonly used connection device in electrical and communication equipment. They are related to the stability and reliability of signal input and output of electrical and communication equipment. Electrical connectors include plugs and sockets. Usually, the plug is connected to the cable and the socket is connected to the device to realize the electrical connection between the cable and the device.

[0003] Chinese Patent Publication No. CN212659747U discloses a 28-gauge, 4-pin, 3-outlet electrical connector. The 28-gauge, 4-pin, 3-outlet electrical connector includes a plug housing; a socket insulator installed inside the plug housing; a socket cover installed inside the plug housing; an integrated elbow installed on one side of the plug housing; an elbow nut installed on the outside of the connection between the plug housing and the integrated elbow; a first socket installed on the socket cover; a second socket installed on the socket cover; and a third socket installed on the socket cover.

[0004] In the aforementioned patent, the integrated elbow and plug housing are sealed by creating a groove in the elbow nut and placing a sealing ring within the groove. The integrated elbow abuts against the sealing ring, achieving a seal at the connection between the integrated elbow and the plug housing. This sealing method requires high machining precision for the elbow nut. However, during long-term use, if a gap exists between the integrated elbow and the sealing ring, the seal between the integrated elbow and the plug housing can easily decrease, allowing dust and moisture to enter the plug housing and damage the cable inside. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a sealing socket with a novel bent structure to solve the technical problems of cumbersome installation of the sealing ring and low sealing performance between the integrated elbow and the plug housing.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0007] A novel bent-type sealed socket includes a plug assembly and a bend assembly. The bend assembly includes an integral bend and a bend nut. One end of the integral bend is mounted on one side of the plug assembly and connected by the bend nut.

[0008] The integrated elbow has a first bend that bends outward at one end. The corresponding end of the plug assembly has a stepped surface, forming a second bend that mates with the first bend. The end of the first bend abuts against the stepped surface, forming a sealing groove with the second bend. A sealing ring is provided within the sealing groove.

[0009] Furthermore, the inner end of the elbow nut is threaded into the plug assembly. A retaining ring is fixed in the inner cavity between the elbow nut and the integrated elbow to limit and fix the integrated elbow.

[0010] Furthermore, the plug assembly includes a plug housing, a socket cover, and multiple socket components. The second bent portion is located at the tail end of the plug housing. The socket cover is fixed in the inner cavity of the plug housing and has multiple mounting holes that mate with the socket components. Each socket component is fixed in its corresponding mounting hole.

[0011] Furthermore, the plug assembly also includes socket insulators. The socket insulators are disposed between each socket component.

[0012] Furthermore, a connecting nut is provided on the outer ring of the plug housing. An O-ring is provided between the connecting nut and the plug housing.

[0013] Furthermore, the socket also includes a housing assembly comprising a cable cover and a rubber ring. The cable cover is threaded to the end of the integrated elbow. The rubber ring is embedded and fixed within the inner cavity of the cable cover.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This invention features a first bend that curves outward at the end of an integrated elbow. A stepped surface is provided on the corresponding end of the plug assembly, forming a second bend that mates with the first bend. The end of the first bend abuts against the stepped surface, forming a sealing groove with the second bend. A sealing ring is provided within the sealing groove to effectively prevent gaps from forming due to improper installation of the integrated elbow during insertion, thus ensuring a tight seal between the integrated elbow and the plug housing.

[0020] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 and 2 As shown, a novel curved sealed socket includes a plug assembly 1, a bend assembly 2, and a cover assembly 3 connected in sequence. The cover assembly 3 protects the cable in the bend assembly 2. The bend assembly 2 includes an integral bend 4 and a bend nut 5. One end of the integral bend 4 is mounted on one side of the plug assembly 1, and the connection between the integral bend 4 and the plug assembly 1 is achieved by the bend nut 5.

[0023] like Figure 3 As shown, in this embodiment, the end of the integrated elbow 4 is provided with a first bent portion 6 that bends outward. The corresponding end of the plug assembly 1 is provided with a stepped surface, forming a second bent portion 7 that cooperates with the first bent portion 6. The end of the first bent portion 6 abuts against the stepped surface, forming a sealing groove with the second bent portion 7. A sealing ring 8 is provided in the sealing groove, which can further improve the sealing performance between the integrated elbow 4 and the plug assembly 1.

[0024] In this embodiment, the inner end of the elbow nut 5 is threaded into the plug assembly 1. A retaining ring 9 is installed between the elbow nut 5 and the integrated elbow 4. Specifically, a limiting groove is formed on the inner wall of the elbow nut 5. The retaining ring 9 is embedded in the limiting groove and can cooperate with the first bending part 6 on the integrated elbow 4 to achieve limiting and fixing of the integrated elbow 4.

The second bend 7 is located at the tail end of the plug housing 10, and works with the sealing ring 8 to achieve a seal between the plug housing 10 and the integrated elbow 4. The socket cover is fixed in the inner cavity of the plug housing 10, and its surface has multiple mounting holes that mate with the socket components 13. Each socket component 13 is fixed in its corresponding mounting hole. The socket insulator 12 is disposed between each socket component 13 to prevent current leakage and protect personal safety.

[0026] Furthermore, a connecting nut 14 is provided on the outer ring of the plug housing 10 for connecting and fixing the socket and the plug. In some embodiments, an O-ring 15 is provided between the connecting nut 14 and the plug housing 10 to ensure the sealing of the connection between the connecting nut 14 and the plug housing 10.
