Description

Technical Field

[0001] This utility model relates to the field of power cord technology, and in particular to a power cord with an anti-pulling structure. Background Technology

[0002] A power cord is an electrical wire that transmits electric current. Current is typically transmitted point-to-point. Power cords can be categorized into AC (alternating current) power cords and DC (direct current) power cords, depending on their application. AC power cords are typically used for transmitting higher voltage alternating current. Due to the higher voltage, these cords require standardized safety certifications before they can be manufactured.

[0003] In existing power cords, a connecting wire connects the plug and the pin. The plug is connected to the power supply equipment, and the pin is connected to the equipment. During use, the connecting wire is easily pulled by external force, causing the pin to separate from the equipment. This results in the power cord being unable to supply power to the equipment, reducing the stability during use. Utility Model Content

[0004] The main purpose of this utility model is to provide a power cord with an anti-pull structure.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A power cord with an anti-pull structure includes a first connecting component, a connecting wire installed on one side of the first connecting component, a second connecting component fixed to one end of the connecting wire, cavities symmetrically formed on both sides of the second connecting component, a fastening component installed in the cavity, the fastening component including a support column fixed in the cavity, limit plates installed on both sides of the support column, and a fastening plate disposed between the limit plates, the fastening plate being rotatably connected to the support column, friction textures formed on the side of the fastening plate away from the cavity, and a return spring disposed on the back end of the fastening plate.

[0007] Preferably, the first connection component includes a plug and a conductive sheet, and the conductive sheet is fixed to the plug.

[0008] Preferably, the second connecting component includes a pin, a slot, and a conductive post.

[0009] Preferably, the slot is formed on the pin, and the conductive post is fixed in the slot.

[0010] Preferably, the plug and the pin have anti-slip textures formed on both the upper and lower side walls.

[0011] Preferably, one end of the return spring is fixed to the pin, and the other end of the return spring abuts against the fastening plate.

[0012] Preferably, the connecting wires are electrically connected to the plug and the pin, respectively.

[0013] The beneficial effects of this technology are:

[0014] By setting up a fastening assembly, when the pin is connected to the device, it enters the device. At this time, the fastening plate is subjected to force and rotates along the support column. While rotating, the return spring is pressed down and retracted. The reaction force applied by the return spring causes the fastening plate to abut against the inner wall of the device, and the friction texture increases the friction force, thereby increasing the connection strength, preventing the pin from being pulled away from the device by external forces, and improving the stability during power supply use.

[0020] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0021] like Figures 1-3As shown, this embodiment provides a power cord with an anti-pull structure, including a first connecting component 1. A connecting wire 2 is installed on one side of the first connecting component 1. The connecting wire 2 is used for conducting electricity. A second connecting component 3 is fixed to one end of the connecting wire 2. Cavities 4 are symmetrically opened on both sides of the second connecting component 3. The cavities 4 facilitate the entry of fastening pieces 503. A fastening component 5 is installed in the cavity 4. The fastening component 5 includes a support column 501 fixed in the cavity 4. The support column 501 can support one end of the fastening piece 503. The support column 501 has two sides... Each device is equipped with a limiting plate 502, which can limit the fastening plate 503. The fastening plate 503 is provided between the limiting plates 502. The fastening plate 503 can improve the connection strength between the pin 301 and the equipment. The fastening plate 503 is rotatably connected to the support column 501. Friction texture 504 is provided on the side of the fastening plate 503 away from the cavity 4. The friction texture 504 can increase the friction of the fastening plate 503. A return spring 505 is provided on the back end of the fastening plate 503. The return spring 505 can reset the fastening plate 503.

[0022] like Figure 1 As shown, the first connection component 1 includes a plug 101 and a conductive sheet 102, and the conductive sheet 102 is fixed on the plug 101, so that the plug 101 can be connected to an external power source through the conductive sheet 102.

[0023] like Figures 1-2 As shown, the second connecting component 3 includes a pin 301, a slot 302, and a conductive post 303, which facilitates connection to the device via the second connecting component 3.

[0024] like Figures 1-2 As shown, the slot 302 is formed on the pin 301, and the conductive post 303 is fixed in the slot 302, which enables the pin 301 to be connected to the equipment through the conductive post 303 in the slot 302.

[0025] like Figures 1-2 As shown, anti-slip textures 6 are formed on both the upper and lower side walls of plug 101 and pin 301, which facilitates the connection of plug 101 and pin 301 by workers to improve the anti-slip performance.

[0026] like Figures 2-3 As shown, one end of the return spring 505 is fixed to the pin 301, and the other end of the return spring 505 abuts against the fastening piece 503, so that the fastening piece 503 can be reset by the return spring 505.

[0027] like Figure 1 As shown, the connecting wire 2 is electrically connected to the plug 101 and the pin 301 respectively, so as to facilitate the conduction of electricity through the connecting wire 2.

[0028] The working principle of this device is as follows: When using this device, the operator first inserts the pin 301 into the interface of the device, and then connects the plug 101 to the external power source. During the connection process, the anti-slip performance is improved by the anti-slip texture 6. After the connection is completed, the conductive sheet 102, the connecting wire 2 and the conductive post 303 conduct electricity, thereby realizing the power supply to the device. During the connection process, the pin 301 enters the device. At this time, the fastening plate 503 is subjected to force and rotates along the support post 501. At the same time, the return spring 505 is pressed down to retract. The reaction force applied by the return spring 505 makes the fastening plate 503 abut against the inner wall of the device, and the friction texture 504 increases the friction force, thereby increasing the connection strength and preventing the pin 301 from being pulled away from the device by external force, thus improving the stability of the power supply during use.
