Abstract
Description
Technical Field
[0001] This utility model belongs to the field of connector technology, specifically relating to an anti-loosening socket. Background Technology
[0002] Electrical appliances are powered by plugs and sockets. During use, the plug may come loose from the socket due to accidental pulling or vibration, causing a sudden power outage, which can damage the appliance or result in data loss. Utility Model Content
[0003] The purpose of this utility model embodiment is to provide an anti-loosening socket, which aims to solve the problem that when existing sockets are electrically connected to the plug of electrical appliances, the plug is easily loosened from the socket due to unintentional pulling or vibration of the electrical appliance, resulting in sudden power loss of the electrical appliance, damage to the electrical appliance or data loss.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] An anti-loosening socket includes a housing, a clamping elastic element, a tightening element, and a plug-in element. The end of the housing has a plug-in interface for inserting a plug. The plug-in element is installed on the housing and extends into the plug-in interface. The clamping elastic element is disposed between the plug-in element and the housing. The tightening element is rotatably installed on the housing and threadedly connected to one end of the clamping elastic element. The other end of the clamping elastic element is located on the periphery of the plug-in interface.
[0006] The clamping elastic member has a protrusion at one end near the tightening member. When the tightening member rotates relative to the clamping elastic member in a first direction, the tightening member can squeeze the protrusion so that the end of the clamping elastic member away from the tightening member retracts toward the center of the insertion interface.
[0007] Furthermore, the clamping elastic element includes a connecting portion and two opposing elastic pieces connected to one side of the connecting portion. The connecting portion is threadedly connected to the tightening element. The protrusion has two parts, which are disposed opposite to each other on the outer wall of the connecting portion. A notch is provided on the side of the connecting portion near the elastic pieces. The notch is located between the two protrusions. The two elastic pieces are located on opposite sides of the insertion interface.
[0008] When the tightening member rotates relative to the connecting part in the first direction, the tightening member squeezes the protrusion to deform the notch, thereby causing the two elastic pieces to move towards each other and move closer to the center of the insertion interface.
[0009] Furthermore, the inner wall of the tightening member is provided with grooves corresponding to the two protrusions respectively. The grooves have arc-shaped surfaces for pressing against the protrusions. The arc-shaped surfaces extend in the first direction and gradually move away from the axis of the tightening member along the path in the first direction.
[0010] Furthermore, the notch is located in the middle of the connecting portion.
[0011] Furthermore, the outer shell has a first channel communicating with the insertion interface, and the elastic sheet passes through the first channel.
[0012] Furthermore, the housing has a second channel through which the tightening member passes.
[0013] Furthermore, the tightening member has a handle that extends out of the housing through the second channel.
[0014] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows:
[0015] This invention, by rotating the tightening member in the first direction, allows the tightening member to press against the protrusion on the clamping elastic member. This causes the end of the clamping elastic member away from the tightening member to converge toward the center of the socket. After the plug is inserted into the socket and electrically connected to the connector, rotating the tightening member drives the clamping elastic member to converge and clamp the plug, effectively preventing the plug from coming off the connector and thus preventing the plug from coming off the socket, ensuring good power supply to the electrical equipment.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] See Figures 1 to 7 As shown, this embodiment of the utility model provides an anti-loosening socket. The anti-loosening socket includes a housing 1, a clamping elastic element 2, a tightening element 3, and a plug-in element 4. The housing 1 has a plug-in interface 11 at its end for inserting a plug 100. The plug-in element 4 is mounted on the housing 1 and extends into the plug-in interface 11 for electrical connection with the plug 100 to enable power supply. The clamping elastic element 2 is disposed between the plug-in element 4 and the housing 1. The tightening element 3 is rotatably mounted on the housing 1, sleeved on one end of the clamping elastic element 2 and threadedly connected to one end of the clamping elastic element 2. The other end of the clamping elastic element 2 is positioned around the plug-in interface 11.
[0028] The clamping elastic element 2 has a protrusion 210 at one end near the tightening element 3. When the tightening element 3 rotates relative to the clamping elastic element 2 in the first direction C, the tightening element 3 can squeeze the protrusion 210, so that the end of the clamping elastic element 2 away from the tightening element 3 moves toward the middle of the plug interface 11. After the plug 100 is inserted into the plug interface 11 and connected to the plug connector 4, the plug 100 is clamped by rotating the tightening element 3 to drive the clamping elastic element 2 to move toward the middle of the plug interface 11. This effectively prevents the plug 100 from coming off the socket and ensures good power supply to the electrical equipment.
[0029] In one embodiment, the clamping elastic member 2 includes a connecting portion 21 and two opposing elastic pieces 22 connected to one side of the connecting portion 21. Preferably, the connecting portion 21 is integrally connected to the elastic pieces 22, and the connecting portion 21 is threadedly connected to the tightening member 3. There are two protrusions 210, which are disposed opposite to each other on the outer wall of the connecting portion 21. A notch 211 is provided on the side of the connecting portion 21 near the elastic pieces 22. The notch 211 is located between the two protrusions 210, and the two elastic pieces 22 are located on opposite sides of the insertion interface 11. When the tightening member 3 rotates relative to the connecting portion 21 in the first direction C, the tightening member 3 squeezes the protrusions 210, causing the notch 211 to deform, thereby causing the two elastic pieces 22 to move towards each other and move closer to the center of the insertion interface 11. Thus, the plug 100 can be stably clamped by the two opposing elastic pieces 22 moving closer to each other.
[0030] In one embodiment, the inner wall of the tightening member 3 is provided with grooves 31 corresponding to the two protrusions 210 respectively, so that the protrusions 210 are placed in the grooves 31. The grooves 31 have arc-shaped surfaces 311 for pressing against the protrusions 210. The arc-shaped surfaces 311 are located at the upper end of the protrusions 210 and extend in the first direction C. The arc-shaped surfaces 311 gradually move away from the axis of the tightening member 3 along the path of the first direction C. That is, along the path of the first direction C, the distance from each point on the arc-shaped surfaces 311 to the axis of the tightening member 3 gradually increases. This allows the arc-shaped surfaces 311 to gradually approach the protrusions 210, then contact the protrusions 210, and finally press against the protrusions 210 after the tightening member 3 is rotated in the first direction C. This causes the opening of the notch 211 to shrink and deform, thereby causing the two elastic pieces 22 to close together. In this embodiment, the notch 211 is located in the middle of the connecting part 21, so that the two elastic pieces 22 can close as synchronously as possible.
[0031] In one embodiment, the outer casing 1 has a first channel 5 communicating with the plug interface 11, and the elastic piece 22 is inserted through the first channel 5, so that after the tightening member 3 is rotated in the first direction C, the elastic piece 22 is pressed from the first channel 5 into the plug interface 11, thereby clamping the plug 100 placed in the plug interface 11.
[0032] In one embodiment, the outer casing 1 has a second channel 6 through which the tightening member 3 passes. Specifically, the tightening member 3 has a handle 32, which extends out of the outer casing 1 through the second channel 6, making it convenient to rotate the tightening member 3 by operating the handle 32.
[0033] In summary, this utility model, by rotating the tightening member 3 in the first direction C, allows the tightening member 3 to press and clamp the protrusion 210 on the clamping elastic member 2. This causes the end of the clamping elastic member 2 away from the tightening member 3 to move towards the connector 4. Thus, after the plug 100 is electrically connected to the connector 4 through the plug interface 11, rotating the tightening member 3 drives the clamping elastic member 2 to clamp the plug 100, effectively preventing the plug 100 from coming off the connector 4. This prevents the plug 100 from coming off the socket, ensuring good power supply to the electrical equipment, and thus ensuring the normal operation of the electrical equipment and the safe storage of data.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
