Description

Technical Field

[0001] This utility model relates to the technical field of plug connection devices, and in particular to an electrical plug connection device with an anti-detachment structure. Background Technology

[0002] An electrical plug consists of two parts: the plug body and the socket. Electrical circuitry is established through mechanical insertion. The plug typically has conductive contacts (such as metal pins or prongs), while the socket is equipped with corresponding contacts or slots. Together, they transmit current or signals. Electrical plug connection devices with anti-dislodgement structures significantly improve the connection stability between the plug and socket, effectively preventing detachment due to external pulling, vibration, or accidental contact. This ensures continuous power supply to the equipment and avoids equipment damage or operational interruption caused by unexpected power outages.

[0003] Chinese patent document CN217823507U discloses a plug with an anti-detachment structure, including a disassembly bracket disposed on both sides of the plug body. A limiting shaft is installed at the lower end of the disassembly bracket, and the limiting shaft is fixedly connected to the disassembly bracket. The limiting shaft is slidably connected to the plug body through a slot. By installing the limiting shaft, the device can be easily disassembled by the operator using a push shaft, enhancing the device's practicality. Installing the clamping shaft, in conjunction with the limiting spring, can clamp the plug body inside the socket frame, preventing the device from easily separating from the socket frame when subjected to vibration, thus affecting the charging of the device.

[0004] The existing technology has the following problems:

[0005] Although the above-mentioned utility model can prevent the socket frame from separating, the process of unlocking requires pressing the push rod first, then pulling the plug, and finally pulling out the push rod. This process is cumbersome and requires operators to spend a lot of time and effort, which reduces the efficiency of use. In addition, the lack of an effective guidance and positioning structure makes it difficult for the plug to be accurately inserted into the socket, and positional deviation is easy to occur. Utility Model Content

[0006] This invention provides an electrical plug connection device with an anti-detachment structure to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 5 As shown, an electrical plug connection device with an anti-detachment structure includes a base 1, a socket 2 is provided inside the base 1, a plug 3 is installed on the outside of the socket 2, two positioning plates 4 are provided on the front side of the base 1, two plug-in plates 5 are provided on the outer periphery of the plug 3, the plug-in plates 5 are slidably connected to the inside of the positioning plates 4, and an anti-detachment mechanism 6 is provided inside the plug-in plates 5.

[0027] A positioning rod 7 is provided on the rear side of the plug plate 5. The positioning rod 7 is slidably connected to the middle part of the positioning plate 4, and the rear end of the positioning rod 7 is slidably connected to the inside of the base 1.

[0028] It should be noted that the base 1 is the fundamental support component of the entire device, providing a stable installation platform for other components. It contains a socket 2, providing space and structural support for electrical connections. Socket 2 is a crucial part of the electrical connection, with a specific interface structure that matches the plug 3 to transmit current or signals. Precise installation and fixation ensure reliable electrical performance. Plug 3 is key to connecting to external equipment. The positioning plate 4 accurately guides and positions the plug plate 5, ensuring accurate mating of plug 3 and socket 2, avoiding poor connection or electrical faults. It also provides installation and sliding space for some components of the anti-detachment mechanism 6. The anti-detachment mechanism 6, located inside the plug plate 5, is an important part of the anti-detachment structure, responsible for transmitting mechanical connection forces and providing an installation carrier for the components of the anti-detachment mechanism 6, preventing plug 3 from accidentally falling off.

[0029] The positioning rod 7 plays a role in assisting positioning and enhancing connection stability. During the process of inserting the plug 3 into the socket 2, it slides along the track in the middle of the positioning plate 4 to ensure accurate docking position, improves mechanical strength, makes the connection more stable and reliable, and effectively prevents the plug 3 from falling off due to shaking or external force.

[0030] like Figure 5 As shown, the anti-detachment mechanism 6 includes a wedge 64, which is slidably connected inside the plug plate 5. The upper and lower sides of the wedge 64 are provided with locking blocks 65, which are slidably connected inside the positioning plate 4.

[0031] It should be noted that the wedge 64 is a key moving component of the anti-detachment mechanism 6. Its special shape design allows it to drive the two locking blocks 65 to move simultaneously when subjected to a specific external force, and achieves the anti-detachment function by cooperating with the locking blocks 65. When the plug 3 is inserted into the socket 2 to the appropriate position, the movement of the wedge 64 drives the locking blocks 65 to move, which in turn engage with a specific slot inside the positioning plate 4, enhancing the connection stability between the plug 3 and the socket 2 and effectively preventing detachment.

[0032] like Figure 5 As shown, a connecting rod 62 is fixedly connected to the front side of the wedge block 64, and a limit ring is slidably connected to the outer periphery of the connecting rod 62. The limit ring is fixedly connected inside the plug plate 5. A handle 61 is fixedly connected to the front side of the connecting rod 62, and the handle 61 is slidably connected inside the plug plate 5.

[0033] It should be noted that the connecting rod 62, as a component for transmitting operating force, is connected to the wedge block 64 at one end and the handle 61 at the other end. When the operator pushes or pulls the handle 61, it can move the connecting rod 62, which in turn moves the wedge block 64, thereby realizing the locking and unlocking operation of the anti-drop mechanism. The limit ring restricts the movement trajectory of the connecting rod 62 to ensure the accuracy and stability of the operation. The handle 61 provides the operator with a direct operating interface, making it convenient to control the anti-drop mechanism 6. Holding and applying pushing or pulling force can realize locking and unlocking, making the plug 3 easier and more reliable to insert and remove.

[0034] like Figure 5 As shown, a limiting plate 68 is fixedly connected to one side of each of the two locking blocks 65. A sliding rod 66 is slidably connected to the middle of the limiting plate 68, and the sliding rod 66 is fixedly connected inside the plug-in plate 5.

[0035] It should be noted that the function of the limiting plate 68 is to limit the range of motion of the locking block 65, ensure that the locking block 65 slides in a specific direction, avoid deviation or jamming, and ensure the normal operation of the anti-drop mechanism; the slide rod 66 provides guidance and support for the sliding of the limiting plate 68, so that the limiting plate 68 slides smoothly and accurately, driving the locking block 65 to accurately engage and disengage, ensuring the reliability of the anti-drop mechanism.

[0036] like Figure 5As shown, a compression spring 63 is provided on the outer periphery of the connecting rod 62, and the compression spring 63 is located between the limiting ring and the wedge block 64.

[0037] It should be noted that the function of the compression spring 63 is to provide elastic force to allow the wedge block 64 to automatically reset when the anti-drop mechanism is unlocked. After the operator pulls the handle 61 to move the wedge block 64 to unlock, it is compressed and stores elastic potential energy; when the handle 61 is released, it releases elastic potential energy to push the wedge block 64 back to its initial position, so that the locking block 65 also returns to its original position, ensuring the stability of the anti-drop mechanism in the non-operational state.

[0038] like Figure 5 As shown, a tension spring 67 is provided between the two limiting plates 68, and the tension spring 67 is fixedly sleeved on the outer periphery of the slide rod 66.

[0039] It should be noted that the function of the tension spring 67 is to assist the locking block 65 in quickly resetting when the anti-detachment mechanism is unlocked. When the wedge block 64 moves, the tension spring 67 releases its elastic potential energy, pulling the two limit plates 68 closer together, causing the locking block 65 to exit the positioning plate 4; when the wedge block 64 resets, it stores elastic potential energy, which improves the operating efficiency and reliability of the anti-detachment mechanism.

[0040] like Figure 3 As shown, a groove 8 is provided on the upper part of the plug 3.

[0041] It should be noted that the groove 8 provides a better grip position for the operator, making it easier to plug and unplug the plug 3.

[0042] The working principle of this utility model is as follows: When it is necessary to connect the plug 3 to the socket 2, the operator holds the handle 61, overcomes the elastic force of the compression spring 63, and pulls the handle 61, causing the connecting rod 62 to move the wedge block 64. When the wedge block 64 moves, the tension spring 67 pulls the locking block 65 inward, causing the locking block 65 to exit the positioning plate 4. At this time, the anti-drop mechanism 6 is in the unlocked state. Next, the plug 3 is inserted into the socket 2. The plug plate 5 slides along the positioning plate 4, and the positioning rod 7 also slides along the track inside the positioning plate 4 and the base 1, ensuring that the plug 3 is accurately inserted into the socket 2. When the plug 3 is inserted into the appropriate position, the handle 61 is released, the compression spring 63 releases its elastic potential energy, pushes the wedge block 64 to move, and the wedge block 64 causes the locking block 65 to extend outward, so that the locking block 65 is engaged in a specific slot or structure inside the positioning plate 4, thereby locking the anti-drop mechanism and firmly connecting the plug 3 to the socket 2 to prevent it from falling off. When you need to unplug the plug 3, hold the handle 61 again and follow the unlocking process described above to unlock the anti-drop mechanism 6, and then you can easily unplug the plug 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
