Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes an anti-detachment power cord connector.

[0039] Embodiment 1;

[0040] Please refer to Figure 1-8 , an anti-detachment power cord connector, comprising:

[0041] A male end 1 for connecting to a charger, and a first connection component 3 is arranged inside the male end 1;

[0042] A female end 2 for connecting to a power supply, and a second connection component 4 is arranged inside the female end 2;

[0043] The first connection component 3 is inserted into the second connection component 4 to electrically connect the male end 1 and the female end 2;

[0044] A waterproof component 5 is arranged on the male end 1 and the female end 2, enabling the male end 1 and the female end 2 to be in interference fit;

[0045] A clamping component 6 is arranged on the male end 1 and the female end 2 for the male end 1 and the female end 2 to be hermetically clamped under the cooperation of the waterproof component 5.

[0046] During use, pinch both sides of the clamping component 6 with fingers and move it towards the inside of the male end 1. Since the clamping component 6 is arranged on the male end 1 and the female end 2, when the clamping component 6 is moved, it can drive the male end 1 to move to one side of the female end 2. Then insert the outer surface of the male end 1 into the inside of the female end 2, so that the male end 1 can drive the first connection component 3 arranged inside it to move and insert it into the inside of the second connection component 4 arranged inside the female end 2. Since the outer surface of the male end 1 is provided with the waterproof component 5, when the male end 1 moves, it can drive the outer surface of the waterproof component 5 to insert into the inside of the female end 2 and be in interference fit with its inner wall, thus preventing water from entering the inside of the male end 1 and the female end 2. During the continuous movement of the male end 1, the clamping component 6 arranged on the male end 1 can be clamped with the clamping component 6 arranged on the female end 2, preventing the anti-drop power cord connector from falling off during use.

[0047] In the utility model, by pinching both sides of the clamping component 6 and moving it towards the inside of the male end 1, then inserting the outer surface of the male end 1 into the inside of the female end 2, the male end 1 can drive the first connection component 3 arranged inside it to move and insert it into the inside of the second connection component 4 arranged inside the female end 2. At the same time, it can drive the outer surface of the waterproof component 5 to insert into the inside of the female end 2 and be in interference fit with its inner wall, thus achieving the waterproof effect. During the continuous movement of the male end 1, the clamping component 6 arranged on the male end 1 can be clamped with the clamping component 6 arranged on the female end 2. Since the clamping component 6 is of a snap - type structure, it is convenient for disassembly and installation, and the anti-drop power cord connector has a small volume, thus improving the practicability of the anti-drop power cord connector.

[0048] Further, for the above - mentioned first connection component 3, the first connection component 3 includes a first installation groove 301, the first installation groove 301 is opened inside the male end 1, a power pin 302 is fixedly installed inside the first installation groove 301, and a signal pin 303 is fixedly installed inside the first installation groove 301.

[0049] The inside of the first installation groove 301 is adapted to the outer surface diameters of the power pin 302 and the signal pin 303, which is convenient for fixing their positions for installation and facilitating their insertion with the second connection component 4, reducing the operation requirements and making their mutual matching better.

[0050] Furthermore, for the above-mentioned second connection component 4, the second connection component 4 includes a second installation groove 401, the second installation groove 401 is opened inside the female end 2, a power supply cylinder 402 is fixedly installed inside the second installation groove 401, and a signal cylinder 403 is fixedly installed inside the second installation groove 401;

[0051] The inside of the second installation groove 401 is inserted and arranged with the outer surface of the male end 1.

[0052] When the male end 1 is inserted into the female end 2, the male end 1 drives the power supply pin 302 and the signal pin 303 to move in cooperation with the first installation groove 301, and inserts them into the inside of the second installation groove 401. Since the outer surfaces of the power supply cylinder 402 and the signal cylinder 403 are fixedly installed inside the second installation groove 401, when the power supply pin 302 and the signal pin 303 enter the inside of the second installation groove 401, the power supply pin 302 can be inserted into the inside of the power supply cylinder 402, and at the same time the signal pin 303 is inserted into the inside of the signal cylinder 403, so that the electrical connection is completed, which is more convenient.

[0053] Furthermore, for the above-mentioned waterproof component 5, the waterproof component 5 includes an installation groove 501 and a first sealing ring 502. The installation groove 501 is opened on the outer surface of the male end 1. The inside of the first sealing ring 502 is sleeved with the outer surface of the female end 2. A second sealing ring 503 is sleeved inside the installation groove 501, and the outer surface of the second sealing ring 503 is attached to the inner wall of the second installation groove 401.

[0054] The first sealing ring 502 is arranged on the outer surface of the female end 2. When fixedly installing between the female end 2 and the installation part, by arranging the first sealing ring 502 between the female end 2 and the installation part, the sealing performance between the female end 2 and the installation part can be improved; when the male end 1 is inserted into the female end 2, the male end 1 can drive the installation groove 501 to move. When the installation groove 501 moves, it can drive the second sealing ring 503 arranged inside it to move, and make it enter the inside of the female end 2, and the outer surface of the second sealing ring 503 is in interference fit with the inner wall of the female end 2, so as to realize the waterproof function between the male end 1 and the female end 2.

[0055] Furthermore, for the above-mentioned clamping component 6, the clamping component 6 includes a spring piece 601 and a clamping groove 602. One end of the spring piece 601 is fixedly connected to one side of the male end 1, a pressing block 603 is fixedly connected to one side of the spring piece 601, and a clamping block 604 is fixedly connected to one end of the spring piece 601;

[0056] The clamping groove 602 is opened on one side of the female end 2, and the inside of the clamping groove 602 is clamped with the outer surface of the clamping block 604.

[0057] By pinching the pressing block 603 to move it inwardly towards the male end 1, when the pressing block 603 moves, it can drive the elastic piece 601 fixedly connected to one side of it to move. When the elastic piece 601 moves, it can drive the clamping block 604 fixedly connected to one end of it to move. During the movement of the elastic piece 601, one side of it fits with one side of the male end 1, and then drives the male end 1 to move towards one side of the female end 2 and insert it into the interior of the female end 2. Since the card slot 602 is formed on one side of the female end 2, further under the continuous movement of the male end 1 and the clamping block 604, one side of the clamping block 604 can move to one side of the card slot 602. Thus, when the pressing block 603 is released, under the elastic force of the elastic piece 601, it can drive the clamping block 604 fixedly connected to one end of it to move in a reset manner and drive it to move into the interior of the card slot 602 to complete the clamping connection, thereby preventing the male end 1 and the female end 2 from falling off during use and improving the stability during their connection process.

[0058] Further, for the above-mentioned female end 2, an installation plate 7 is fixedly connected to the outer surface of the female end 2, an installation hole 8 is formed on one side of the installation plate 7, and one side of the installation plate 7 is in fit with one side of the first sealing ring 502.

[0059] By inserting one end of the female end 2 into the interior of the connecting member and driving the installation plate 7 fixedly installed on its outer surface to fit with one side of the connecting member, since one side of the installation plate 7 is in fit with one side of the first sealing ring 502, it can thereby increase the sealing performance between the female end 2 and the connecting member. Then, by inserting a bolt into the interior of the installation hole 8 and threadedly installing it with the connecting member, it can cooperate with the installation plate 7 to fixedly install the position of the female end 2.

[0060] Further, for the above-mentioned male end 1, the male end 1 and the female end 2 are made of DSM PA46GF33 material.

[0061] DSM material can make the male end and the female end lighter, stronger and more durable; PA46 material can endow the male end and the female end with excellent wear and abrasion resistance, especially when used in high-temperature and dry friction environments; GF33 material can make the male end and the female end have excellent chemical resistance and oil resistance.

[0062] Working principle: When in use, by pinching the pressing block 603 to move it inwardly towards the inner side of the male terminal 1, when the pressing block 603 moves, it can drive the elastic piece 601 fixedly connected to one side of it to move. When the elastic piece 601 moves, it can drive the clamping block 604 fixedly connected to one end of it to move. During the movement of the elastic piece 601, one side of it fits with one side of the male terminal 1, and then drives the male terminal 1 to move towards one side of the female terminal 2 and insert it into the interior of the female terminal 2. At the same time, the male terminal 1 can drive the mounting groove 501 to move. When the mounting groove 501 moves, it can drive the second sealing ring 503 arranged inside it to move and enter the interior of the female terminal 2, and the outer surface of the second sealing ring 503 is in interference fit with the inner wall of the female terminal 2. At the same time, the male terminal 1 can cooperate with the first mounting groove 301 to drive the power pin 302 and the signal pin 303 to move and insert them into the interior of the second mounting groove 401. Since the outer surfaces of the power cylinder 402 and the signal cylinder 403 are fixedly installed inside the second mounting groove 401, when the power pin 302 and the signal pin 303 enter the interior of the second mounting groove 401, the power pin 302 can be inserted into the interior of the power cylinder 402, and at the same time the signal pin 303 can be inserted into the interior of the signal cylinder 403 to complete the electrical connection. Since the card slot 602 is opened on one side of the female terminal 2, during the continuous movement of the male terminal 1 and the clamping block 604, one side of the clamping block 604 can move to one side of the card slot 602. Then when the pressing block 603 is released, under the elastic force of the elastic piece 601, it can drive the clamping block 604 fixedly connected to one end of it to move in a reset manner and drive it to move into the interior of the card slot 602 to complete the clamping connection.

[0063] Through the above technical solution: 1. By pinching both sides of the clamping component 6 and moving it inwardly towards the inner side of the male terminal 1, and then inserting the outer surface of the male terminal 1 into the interior of the female terminal 2, the male terminal 1 can drive the first connection component 3 arranged inside it to move and insert it into the interior of the second connection component 4 arranged inside the female terminal 2. At the same time, it can drive the outer surface of the waterproof component 5 to insert into the interior of the female terminal 2 and be in interference fit with its inner wall, so as to achieve the waterproof effect. During the continuous movement of the male terminal 1, the clamping component 6 arranged on the male terminal 1 can be clamped with the clamping component 6 arranged on the female terminal 2. Since the clamping component 6 is a snap - type structure, it is convenient to disassemble and install it, and the anti - detachment power cord connector has a small volume, thus improving the practicality of the anti - detachment power cord connector.

[0064] 2. By pinching the pressing block 603 to move it inwardly towards the male end 1, when the pressing block 603 moves, it can drive the elastic piece 601 fixedly connected to one side of it to move. When the elastic piece 601 moves, it can drive the clamping block 604 fixedly connected to one end of it to move. During the movement of the elastic piece 601, one side of it is brought into contact with one side of the male end 1, and then the male end 1 is driven to move towards one side of the female end 2 and inserted into the interior of the female end 2. Since the card slot 602 is opened on one side of the female end 2, further under the continuous movement of the male end 1 and the clamping block 604, one side of the clamping block 604 can be moved to one side of the card slot 602. Then, when the pressing block 603 is released, under the elastic force of the elastic piece 601, the clamping block 604 fixedly connected to one end of it can be driven to move in a reset manner and driven to move into the interior of the card slot 602 to complete the clamping connection, thereby preventing the male end 1 and the female end 2 from falling off during use and improving the stability during their connection process;

[0065] 3. By arranging the first sealing ring 502 between the female end 2 and the mounting member, the sealing performance between the female end 2 and the mounting member can be improved; when the male end 1 and the female end 2 are plugged together, the male end 1 can drive the mounting groove 501 to move. When the mounting groove 501 moves, it can drive the second sealing ring 503 arranged inside it to move and enter the interior of the female end 2, and the outer surface of the second sealing ring 503 is in interference fit with the inner wall of the female end 2, thereby enabling the waterproof function between the male end 1 and the female end 2.

[0066] Embodiment Two;

[0067] It includes a male end and a female end. An installation groove is opened inside the male end, and a bidirectional screw rod is rotatably arranged inside the installation groove. One end of the bidirectional screw rod is fixedly connected with a turning handle. Two moving blocks are threadedly connected to the threaded surface of the bidirectional screw rod. One side of each of the two moving blocks is fixedly connected with a connecting block. One end of the connecting block is fixedly connected with a wedge-shaped block. A wedge-shaped groove is opened inside the female end, and the outer surface of the wedge-shaped block is slidably arranged inside the wedge-shaped groove.

[0068] During use, by plugging the male end and the female end together and then rotating the turning handle, the bidirectional screw rod fixedly connected to one side of it can be driven to rotate. When the bidirectional screw rod rotates, the two moving blocks threadedly connected to its threaded surface can be driven to move relatively. When the moving blocks move, the connecting blocks fixedly connected to one side of them can be driven to move. When the connecting blocks move, the wedge-shaped blocks fixedly connected to one end of them can be driven to move. Since a wedge-shaped groove is opened inside the female end and the female end and the male end are in a plugged state, when the wedge-shaped block moves, its outer surface can be brought into contact with the interior of the wedge-shaped groove to complete the clamping and fixing.

[0069] In the present utility model, turning the turning handle drives the bidirectional screw to rotate. The bidirectional screw can drive two sets of moving blocks to move relatively. The moving blocks can drive the connecting blocks to move, and the connecting blocks can drive the wedge blocks fixedly connected to one end thereof to move. Since a wedge-shaped groove is formed inside the female end and the female end and the male end are in an inserted connection state, when the wedge block moves, its outer surface can be fitted with the inside of the wedge-shaped groove, and during the continuous movement, it can cooperate with the inclined surface of the wedge block and the wedge-shaped groove to perform extrusion movement, thereby further improving the tightness between the male end and the female end.

[0070] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
