Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a self-locking quick connector. Background Technology

[0002] Quick-connect connectors are the most convenient plug-and-play connection method, especially advantageous in challenging environments where pipe connections are difficult. However, due to frequent plugging and unplugging, the elasticity of the metal contacts inside the socket gradually diminishes, leading to poor contact over time. This can cause the plug to detach when the socket is subjected to other forces, limiting its usability and compromising the secure connection between the plug and the appliance. Therefore, a self-locking connector is needed.

[0003] A search revealed a self-locking connector plug with patent publication number CN213093472U, comprising an insulating rubber sleeve, terminals, a sealing sleeve, a plug connector, and a socket. The insulating rubber sleeve has terminals on its inner side, a sealing sleeve at its front end, and pressing pads at both ends. The bottom of the sealing sleeve has a plug connector, and the bottom panel of the plug connector has a socket. A heat dissipation groove is located on the back of the plug connector. This plug assembly can self-lock the terminals, preventing loosening under certain external force, thus ensuring a secure connection between the appliance and the plug assembly. One end of the plug is fixed to the appliance's terminals, while the other end connects to a power strip via a power cord to supply power to the appliance. The pressing pads serve as the plug's insertion and removal contact points, further isolating the human body from the plug and facilitating force application to the plug, allowing for quick removal from the appliance.

[0004] Based on the above search and analysis of existing technologies, it has been found that the self-locking structures of existing self-locking connectors similar to those disclosed above are relatively complex, making it difficult to insert and remove them in one step. Furthermore, they rely excessively on spring elements, which can easily reduce the connection stability of the connector after frequent insertion and removal. Therefore, a self-locking quick-connect connector is proposed to improve upon these problems. Utility Model Content

[0008] The first insertion part is equipped with a plugging and unplugging component, which acts on the unlocking structure to release the locking effect between the elastic limiting member and the limiting sliding hole.

[0009] As a further supplement to this solution, the elastic limiting component includes a self-locking wedge and a compression spring. The protective sleeve is provided with a groove that matches the self-locking wedge. The self-locking wedge is connected to the inner wall of the groove through the compression spring. The self-locking wedge can be inserted into the limiting sliding hole.

[0010] As a further supplement to this solution, the unlocking structure includes a pressure block and a limiting slider. The pressure block is slidably installed inside the limiting sliding hole one, and the limiting slider is fixed to the side end of the pressure block.

[0011] As a further supplement to this solution, the insertion and removal assembly includes a fixed ring, an operating ring, and a limiting slide post. The fixed ring is coaxially fixed to the outside of the first insertion part. The operating ring is coaxially arranged with the fixed ring. One end of the limiting slide post is fixed to the operating ring. One end of the limiting slide post slides through the fixed ring and is fixed with a limiting cap. The fixed ring is provided with a second limiting slide hole for the limiting slide post to slide through. The end of the pressure block away from the insertion groove is provided with a chamfer.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] In this invention, through the coordinated arrangement of the self-locking component and the insertion / removal component, when the first insertion part and the second insertion part are inserted, the operator holds the operating ring and slides it along the length direction of the second insertion part. When the insertion part is inserted into the insertion slot, the self-locking wedge is inserted into the limiting sliding hole to achieve self-locking. When it is necessary to separate the first insertion part and the second insertion part, the operator holds the operating ring and pulls it away from the second insertion part to separate the first insertion part and the second insertion part. Whether it is an insertion operation or a removal operation, it can be completed in one step by the operating ring, making the insertion and removal operation more convenient and faster.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Reference Figure 1-6 The self-locking quick-connect plug shown includes a first plug part 1 connected with a plug 11 and a second plug part 2 provided with a plug groove 21, wherein the plug 11 and the plug groove 21 are plugged into each other.

[0026] A protective sleeve 12 is coaxially mounted on the end of the first plug part 1 near the plug 11 and sleeved on the outside of the plug 11. The protective sleeve 12 can protect the plug 11 and prevent the plug 11 from being completely exposed to the outside. A protective sleeve 22 is coaxially mounted on the end of the second plug part 2 near the plug groove 21. The protective sleeve 22 can provide further protection when connected.

[0027] A self-locking assembly 3 is installed between the first protective sleeve 12 and the second protective sleeve 22. Specifically, the self-locking assembly 3 includes an elastic limiting member installed on the first protective sleeve 12 and a limiting sliding hole 23 provided on the second protective sleeve 22. The elastic limiting member is adapted to the limiting sliding hole 23 to achieve self-locking. More specifically, the elastic limiting member includes a self-locking wedge 303 and a compression spring 304. The first protective sleeve 12 is provided with a groove 13 adapted to the self-locking wedge 303. The self-locking wedge 303 is connected to the inner wall of the groove 13 through the compression spring 304. The self-locking wedge 303 can be inserted into the limiting sliding hole 23. When the connector 11 is inserted into the connector slot 21, the self-locking wedge 303 is inserted into the limiting sliding hole 23 to achieve self-locking.

[0028] An unlocking structure is slidably installed in the limiting slide hole 23 to release the locking effect between the elastic limiting member and the limiting slide hole 23. Specifically, the unlocking structure includes a pressure block 301 and a limiting slider 302. The pressure block 301 is slidably installed on the inner side of the limiting slide hole 23, and the limiting slider 302 is fixed to the side end of the pressure block 301. A limiting slide groove 24 adapted to the limiting slider 302 is provided on the inner wall of the limiting slide hole 23. A plugging and unplugging component is installed on the first plugging part 1. The plugging and unplugging component acts on the pressure block 301, so that the pressure block 301 releases the locking effect between the self-locking wedge 303 and the limiting slide hole 23.

[0029] Regarding the plug-in assembly, specifically, the plug-in assembly includes a fixing ring 4, an operating ring 5, and a limiting slide post 6. The fixing ring 4 is coaxially fixed to the outside of the first plug-in part 1. The operating ring 5 is coaxially arranged with the fixing ring 4. One end of the limiting slide post 6 is fixed to the operating ring 5. One end of the limiting slide post 6 slides through the fixing ring 4 and is fixed with a limiting cap 7. The fixing ring 4 is provided with a limiting sliding hole 41 for the limiting slide post 6 to slide through. The end of the pressure block 301 away from the plug-in groove 21 is provided with a chamfer.

[0030] Based on the above structural arrangement, when the first insertion part 1 and the second insertion part 2 are inserted, the operator holds the operating ring 5 and slides it along the length of the second insertion part 2. When the insertion part 11 is inserted into the insertion slot 21, the self-locking wedge 303 is inserted into the limiting sliding hole 23 to achieve self-locking. When it is necessary to separate the first insertion part 1 from the second insertion part 2, the operator holds the operating ring 5 and pulls it away from the second insertion part 2. The operating ring 5 presses the pressure block 301, causing the pressure block 301 to press the self-locking wedge 303 until the self-locking wedge 303 disengages from the limiting sliding hole 23. As the operating ring 5 continues to be pulled away from the second insertion part 2, it remains in the state of pressing the pressure block 301, that is, the self-locking wedge block 303 is always in the state of disengaging from the limiting sliding hole 23. When the operating ring 5 contacts the fixing ring 4, it pushes the first insertion part 1 away from the second insertion part 2 by pressing the fixing ring 4. At this time, the first insertion part 1 and the second insertion part 2 are separated. It can be seen that both insertion and removal operations can be completed in one step by the operating ring 5, making the insertion and removal operations more convenient and faster.

[0031] In order to enable the self-locking wedge 303 to accurately fit the limiting sliding hole 23 and achieve the locking function, the outer surface of the second insertion part 2 is integrally provided with a guide protrusion 25 along its length direction, and the inner wall of the operating ring 5 is provided with a guide groove 51 that matches the guide protrusion 25. The end of the guide protrusion 25 near the insertion groove 21 is provided with a chamfer, which can make the first insertion part 1 and the second insertion part 2 have a certain degree of fault tolerance when they are inserted, and the insertion is smoother.

[0032] The working principle of this utility model is as follows: When the first plug-in part 1 and the second plug-in part 2 need to be plugged in, the operator holds the operating ring 5 and slides the operating ring 5 along the length direction of the second plug-in part 2. When the plug-in part 11 is plugged into the plug-in groove 21, the self-locking wedge 303 is inserted into the limiting sliding hole 23 to achieve self-locking. At this time, the self-locking wedge 303 is located between the operating ring 5 and the fixed ring 4. When the first plug-in part 1 and the second plug-in part 2 need to be separated, the operator holds the operating ring 5 and pulls it away from the side of the second plug-in part 2. The operating ring 5 squeezes and presses... Block 301 causes the pressure block 301 to press the self-locking wedge block 303 until the self-locking wedge block 303 disengages from the limiting slide hole 23. During the process of continuing to pull the operating ring 5 toward the side away from the second insertion part 2, the operating ring 5 always maintains the state of pressing the pressure block 301, that is, the self-locking wedge block 303 is always in the state of disengaging from the limiting slide hole 23. When the operating ring 5 contacts the fixing ring 4, it pushes the first insertion part 1 toward the side away from the second insertion part 2 by pressing the fixing ring 4. At this time, the first insertion part 1 and the second insertion part 2 are separated.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
