Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, and in particular to a charging plug anti-misinsertion guide component. Background Technology

[0002] As a common electrical connection component, the plug plays a crucial role in various electrical usage scenarios. It consists of an insulating shell, prongs, and other core parts. Plugs come in various specifications to adapt to electrical devices with different voltage and current requirements. By connecting to a socket, they introduce electrical energy from an external power source into the appliance, enabling it to operate normally.

[0003] Existing anti-misinsertion plug devices generally consist of an insulating shell, prongs, a guide structure, and a limiting component. The insulating shell is usually made of high-strength insulating material to prevent users from getting electric shock. The prongs are usually made of copper, which has good conductivity and is responsible for transmitting current. The guide structure is commonly a guide groove or guide post, whose special shape can guide the plug to be accurately inserted into the corresponding socket, avoiding damage to electrical appliances or causing safety accidents due to incorrect insertion.

[0004] While common plug anti-misinsertion designs can ensure connection safety, they have limitations in adapting to various scenarios. Their structures are often designed for specific socket types, with special guide or slot designs. Some anti-misinsertion plugs cannot flexibly switch connection methods, failing to meet the needs of scenarios where ordinary socket power is temporarily required, causing many inconveniences for users. Therefore, a charging plug anti-misinsertion guide component is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a charging plug anti-misinsertion guide component, which aims to improve the problem that the existing anti-misinsertion plugs cannot adapt to various scenarios.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A charging plug anti-misinsertion guide assembly includes an insulating shell and a connector. A telescopic column is fixedly connected inside the insulating shell. A compression spring is sleeved on the outer wall of the telescopic column. A fixing block is fixedly connected to the other end of the telescopic column. Multiple fixing rods are fixedly connected to the top of the fixing block. The outer wall of the fixing block is slidably connected to the inner wall of the insulating shell. Multiple pins are fixedly connected to the outer wall of the insulating shell. A locking assembly is provided inside the insulating shell.

[0008] As a further description of the above technical solution:

[0009] The engaging assembly includes a second limiting spring, one end of which is fixedly connected to a second limiting post, and the other end of which is fixedly connected to the inside of the insulating shell. The outer wall of the second limiting post is slidably connected to the inside of the insulating shell.

[0010] As a further description of the above technical solution:

[0011] A sleeve is fixedly connected to the outer wall of the insulating shell, and a telescopic column two is fixedly connected to the inside of the sleeve. A compression spring two is sleeved on the outer wall of the telescopic column two, and an extension tube is fixedly connected to the other end of the telescopic column two.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the connector has a plug hole, and the inner wall of the connector is fixedly connected to a limiting spring. The other end of the limiting spring is fixedly connected to a limiting post. The outer wall of the limiting post is slidably connected to the inside of the connector.

[0014] As a further description of the above technical solution:

[0015] An inlet wire is fixedly connected to the outer wall of the insulating shell, and an outlet wire is fixedly connected to the outer wall of the connector;

[0016] As a further description of the above technical solution:

[0017] A traction block is fixedly connected to the outer wall of the extension tube, and the top of the pin contacts the plug hole;

[0018] As a further description of the above technical solution:

[0019] One end of the compression spring is fixedly connected to the inside of the sleeve, and the other end of the compression spring is fixedly connected to the inside of the extension tube;

[0020] As a further description of the above technical solution:

[0021] The top of the first limiting post is in contact with the outer wall of the fixing block, and the top of the second limiting post is in contact with the outer wall of the fixing block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the plug is connected to a normal socket, pulling the traction block causes the extension tube to compress the spring two into the sleeve. Since the normal socket is a flat surface without a slot, when the plug approaches, the socket surface touches the fixing rod. The fixing rod is connected to the fixing block, thereby the fixing block compresses the spring one and slides inside the insulating shell. During the sliding, the fixing block compresses the limiting post two and compresses the spring two. When the fixing block slides to a specific position, the spring two pushes the limiting post two into the groove of the fixing block, restricting the position of the fixing block and realizing a safe and stable connection between the plug and the normal socket.

[0024] 2. In this utility model, when the insulating shell is connected to the connector, the pins on the insulating shell precisely align with the plug holes of the connector. The fixing block on the top of the insulating shell and the fixing rod fixed on the top of the fixing block can precisely engage with the corresponding slot of the connector during docking. The fixing block pushes the limiting post to compress the limiting spring, storing elastic potential energy, causing the limiting post to engage in the slot of the fixing block, thus firmly connecting the plug and the connector. The unique shape of the fixing rod is only suitable for connectors with special slots, thereby effectively preventing the plug from being mis-inserted. Attached Figure Description

[0031] 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.

[0032] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a charging plug anti-misinsertion guide assembly, comprising an insulating shell 1 and a connector 4. A telescopic column 7 is fixedly connected inside the insulating shell 1. A compression spring 8 is sleeved on the outer wall of the telescopic column 7. A fixing block 9 is fixedly connected to the other end of the telescopic column 7. Multiple fixing rods 10 are fixedly connected to the top of the fixing block 9. The special design of the fixing rods 10 plays a key role in the anti-misinsertion function. The outer wall of the fixing block 9 is slidably connected to the inner wall of the insulating shell 1. The fixing block 9 compresses the compression spring 8, causing the fixing block 9 to slide within the insulating shell 1, providing mobility to meet connection requirements in different scenarios. Multiple pins 6 are fixedly connected to the outer wall of the insulating shell 1. The pins 6 are key components for electrical connection. A locking assembly is provided inside the insulating shell 1. The connector includes a second limiting spring 17, one end of which is fixedly connected to a second limiting post 16, and the other end of which is fixedly connected to the inside of the insulating shell 1. The outer wall of the second limiting post 16 is slidably connected to the inside of the insulating shell 1. The outer wall of the connector 4 has a plug hole 11 for precise docking with the pin 6 on the insulating shell 1. The inner wall of the connector 4 is fixedly connected to a first limiting spring 12, and the other end of the first limiting spring 12 is fixedly connected to a first limiting post 13. The outer wall of the first limiting post 13 is slidably connected to the inside of the connector 4. The fixing block 9 pushes the first limiting post 13, causing the first limiting post 13 to squeeze the first limiting spring 12 and store elastic potential energy. Finally, the first limiting post 13 is stuck in a specific groove of the fixing block 9, completing a stable connection. Due to the special shape of the fixing rod 10, it can effectively prevent mis-insertion.

[0033] Reference Figures 1 to 3A sleeve 3 is fixedly connected to the outer wall of the insulating shell 1. A telescopic column 14 is fixedly connected inside the sleeve 3. A compression spring 15 is fitted on the outer wall of the telescopic column 14. One end of the compression spring 15 is fixedly connected to the inside of the sleeve 3, and the other end is fixedly connected to the inside of the extension tube 2. The other end of the telescopic column 14 is fixedly connected to the extension tube 2. During movement, the extension tube 2 compresses the compression spring 15, causing the extension tube 2 to gradually enter the sleeve 3. An inlet wire 19 is fixedly connected to the outer wall of the insulating shell 1. The inlet wire 19... The external power supply current is introduced into the entire charging plug anti-misinsertion guide assembly. The outer wall of the connector 4 is fixedly connected to the output wire 5. The output wire 5 transmits the current after being processed by the assembly and connected stably to the electrical equipment. The outer wall of the extension tube 2 is fixedly connected to the traction block 18. Applying external force to the traction block 18 can control the extension and retraction of the extension tube 2, thereby realizing connection in different connection scenarios. The top of the plug 6 contacts the plug hole 11. The top of the first limiting post 13 contacts the outer wall of the fixing block 9. The top of the second limiting post 16 contacts the outer wall of the fixing block 9.

[0034] Working principle: When the insulating shell 1 is connected to the connector 4, the insulating shell 1 is fixed with the pins 6, and the pins 6 and the plug holes 11 pre-drilled on the connector 4 are precisely aligned. The top of the insulating shell 1 is provided with a sliding fixing block 9, and the top of the fixing block 9 is fixed with a fixing rod 10. During the alignment process between the insulating shell 1 and the connector 4, the fixing rod 10 and the fixing block 9 can be precisely inserted into the corresponding slots of the connector 4. The fixing block 9 pushes the limiting post 13. After the limiting post 13 is pushed, it squeezes the limiting spring 12, causing the limiting spring 12 to store elastic potential energy, pushing the limiting post 13 to be locked in the specific slot of the fixing block 9, thereby achieving a stable fixation between the plug and the connector 4. Because of the unique shape design of the fixing rod 10, it can only be used with the connector 4 with a special slot, which can effectively prevent the plug from being mis-inserted.

[0035] When the plug needs to be inserted into the normal socket, the traction block 18 will drive the extension tube 2 to move. During the movement, the extension tube 2 compresses the second spring 15, which in turn causes the extension tube 2 to gradually enter the sleeve 3. Because the surface of the normal socket is flat and does not have a special slot structure, when the plug approaches the normal socket, the flat surface of the socket will contact the fixing rod 10. The fixing rod 10 is fixedly connected to the fixing block 9. Therefore, when the fixing rod 10 is under force, it will drive the fixing block 9 to compress the first spring 8, causing the fixing block 9 to slide inside the insulating shell 1. At the same time, during the sliding process, the fixing block 9 will compress the second limiting post 16. The second limiting post 16 is under force and compresses the second limiting spring 17, causing the second limiting spring 17 to generate elastic potential energy. When the fixing block 9 slides to a specific position, the second limiting spring 17 pushes the second limiting post 16 to be precisely locked in the slot in the fixing block 9, thereby restricting the fixing block 9 and realizing a safe and stable connection between the plug and the normal socket.

[0036] 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.
