Description

Technical Field

[0001] The utility model relates to the technical field of cable accessories, and particularly relates to a pluggable cable connector. Background Art

[0002] Cable accessories, also known as cable connectors or cable joints, are one of the important components of the cable power transmission network, playing an important role at the intermediate connection points and terminal connection points of the cable line to ensure the integrity and functionality of the power transmission network. Traditional cable accessories generally use a threaded structure for connection. The installation process is relatively troublesome, generally requiring specific tools and a certain amount of installation space for turnover. Therefore, it is inconvenient to install in some narrow spaces. Moreover, the cable accessories with a threaded structure itself have relatively high requirements for processing accuracy. Otherwise, due to insufficient thread processing accuracy, the corresponding thread structures may not match, resulting in the problem of inability to connect. In view of this, this application aims to provide a pluggable cable connector, which not only has the function of quick plugging and unplugging, but also has a simple structure, small installation space requirements, large dimensional change margins, and a wide range of applications. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above deficiencies of the prior art and provide a pluggable cable connector, which has the function of quick plugging and unplugging, and has a simple structure and small installation space requirements.

[0004] The technical solution of the utility model is: a pluggable cable connector, including a socket and a plug. A cavity is arranged inside the socket. The cavity is cylindrical, and a ring groove is also arranged inside the socket. The ring groove is coaxially arranged with the cavity. A first boss is arranged in the ring groove, and a first groove is also arranged on the inner wall of the socket. The first groove extends from one end of the socket to the ring groove and finally communicates with the ring groove. The plug is tubular. A second boss is arranged on one end of the plug, and a second groove is arranged on the second boss. The second boss matches the first groove. The second groove matches the first boss. A retaining ring is arranged on the outer surface of the middle part of the plug, and a sealing groove is arranged on the retaining ring. A sealing ring is accommodated in the sealing groove.

[0005] Further, there are multiple first bosses, and they are evenly arranged on the ring groove. Preferably, there are 3 first bosses, which not only ensure the connection effect but also reduce the processing burden.

[0006] Further, there are multiple first grooves, and the number of the first grooves is the same as the number of the second bosses. Preferably, the number of the first grooves is 3.

[0007] Further, gaps are provided between both sides of the second boss and the end of the plug-in. These gaps are used to endow the second boss with good elasticity, enabling the second boss to contract towards the inside of the pipe when being extruded. Preferably, the gaps can extend near the retaining ring but do not exceed the position where the retaining ring is located.

[0008] Further, the distance from the retaining ring to the second boss is adapted to the length of the first groove, enabling the second boss to smoothly enter the annular groove through the first groove. Moreover, the distance from the retaining ring to the second boss and the length of the first groove can both be designed according to actual requirements.

[0009] Further, the sealing groove is arranged on the side of the retaining ring facing the second boss.

[0010] Further, the depth of the sealing groove is less than the diameter of the sealing ring. This can provide a certain amount of axial margin during connection through the sealing ring.

[0011] Advantages of the present utility model compared with the prior art: The pluggable cable connector in this application has a simple structure, requires little space for installation and disassembly, and is convenient for installation and disassembly; moreover, the connection structure is stable, is not easily affected by external forces to impact the connection stability, and the structure can have good adaptability to dimensional margins.

[0018] The following will further elaborate on the present utility model in detail with reference to specific embodiments. The methods or functional components not specifically described in the embodiments are all prior arts; unless otherwise defined, all technical terms and scientific terms used herein have the same meanings as those commonly understood by those skilled in the technical field to which this application belongs.

[0019] Embodiment

[0020] As Figures 1-5 shown, this embodiment is a pluggable cable connector, including a socket 2 and a plug 1. A cavity is provided inside the socket 2. The cavity is cylindrical, and a ring groove 22 is further provided inside the socket 2. The ring groove 22 is coaxially arranged with the cavity. A first boss 23 is provided in the ring groove 22, and a first groove 21 is further provided on the inner wall of the socket 2. The first groove 21 extends from one end of the socket 2 towards the ring groove 22 and finally communicates with the ring groove 22. The plug 1 is tubular. A second boss 11 is provided at one end of the plug 1. A second groove 14 is provided on the second boss 11. The second boss 11 matches the first groove 21. The second groove 14 matches the first boss 23. A retaining ring 12 is provided on the outer surface of the middle part of the plug 1. A sealing groove 13 is provided on the retaining ring 12, and a sealing ring 3 is accommodated in the sealing groove 13.

[0021] In this embodiment, there are 3 first bosses 23, and they are evenly arranged on the ring groove 22. The number of the first grooves 21 and the number of the second bosses 11 are both 3.

[0022] In this embodiment, a gap 15 is provided between both sides of the second boss 11 and the end of the plug 1. This gap 15 is used to make the second boss 11 have good elasticity. When being extruded, the second boss 11 can shrink towards the inner side of the tube. In this embodiment, this gap 15 extends to the vicinity of the retaining ring 12 but does not exceed the position where the retaining ring 12 is located.

[0023] In this embodiment, the distance from the retaining ring 12 to the second boss 11 is adapted to the length of the first groove 21, so that the second boss 11 can smoothly enter the ring groove 22 through the first groove 21. And the distance from the retaining ring 12 to the second boss 11 and the length of the first groove 21 can both be designed according to actual needs.

[0024] In this embodiment, the sealing groove 13 is provided on the side of the retaining ring 12 facing the second boss 11. The depth of the sealing groove 13 is less than the diameter of the sealing ring 3. In this way, a certain amount of axial margin can be provided by the sealing ring 3 during connection.

[0025] The working principle of the pluggable cable connector in this embodiment is as follows: Align the second boss 11 on the plug 1 with the first groove 21 on the socket 2 one by one, and move the plug 1 into the socket 2 until the second boss 11 extends into the annular groove 22. At this time, rotate the plug 1 to make the second boss 11 approach the first boss 23. Since gaps 15 are provided on both sides of the second boss 11, the second boss 11 has a certain elasticity. When continuing to rotate, the second boss 11 will contract inward under the extrusion of the first boss 23 until the second groove 14 is aligned with the first boss 23. At this time, the second boss 11 will rebound, and then stop rotating. The plug 1 and the socket 2 can achieve a stable connection.

[0026] The above are only some embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have combinations and variations of the foregoing various technical features. Without departing from the spirit and scope of the present invention, improvements, variations, equivalent replacements made by those skilled in the art, or the application of the structure or method of the present invention to other fields to achieve the same effect all fall within the protection scope of the present invention.
