[0016] 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.
[0017] Please see Figure 1-6 As shown, a connector anti-misinsertion structure includes a socket 1 and a pin 2 disposed on one side of the socket 1. Both the pin 2 and the socket 1 are cylindrical. One end of the pin 2 is fixed with a sealing plate 3, and one side of the sealing plate 3 is fixed with a handle 4. The inner wall of the handle 4 is connected to a power cord. After the socket 1 and the pin 2 are connected, power can be transmitted. The socket 1 has built-in electronic components that are connected to electronic devices. By setting the sealing plate 3, the gap between the pin 2 and the socket 1 can be sealed after they are inserted to prevent dust from entering the interior. By setting the handle 4, it is convenient for the operator to operate the pin 2 to insert into the socket 1.
[0018] A positioning sleeve 5 is fixed to one side of the socket 1. The inner wall of the positioning sleeve 5 is provided with a sealing groove 6, and a sealing gasket 7 is fixed to the inner wall of the sealing groove 6. By setting the positioning sleeve 5, the pin 2 can be limited after it is inserted into the socket 1. By setting the sealing groove 6, the sealing gasket 7 can be fixedly placed inside it. After the pin 2 is inserted into the socket 1, the two can be effectively sealed. The size of the sealing ring is adapted to the diameter of the sealing groove 6.
[0019] A locking mechanism 8, located on the outside of the positioning sleeve 5, connects the socket 1 and the pin 2. This mechanism secures the socket 1 and pin 2 together, preventing them from falling off. The locking mechanism 8 includes a spring 81 fixed to one side of the socket 1, which is sleeved on the outside of the positioning sleeve 5. A slider 82 is fixed to one end of the spring 81 and slidably connected to the outside of the positioning sleeve 5. A toggle sleeve 83 is fixed to the outside of the slider 82, and two anti-slip textures 84 are mirror-fixed on the outside of the toggle sleeve 83. A limit ring 85 is provided on one side of the slider 82 and is fixed to the outside of the positioning sleeve 5. The inner wall of the positioning sleeve 5 has six through holes 86 arranged in a circular array. A limiting ball 87 is provided inside the through hole 86, and a limiting groove 88 is provided on the outer side of the pin 2. The inner diameter of the limiting groove 88 is adapted to the size of the limiting ball 87. A spring 81 is fixed on one side of the socket 1, and a slider 82 is fixed to one end of the spring 81. Since the spring 81 is sleeved on the outside of the positioning sleeve 5, when the slider 82 moves, it can compress the spring 81 to extend and retract outside the positioning sleeve 5, and the slider 82 moves outside the positioning sleeve 5. The movement can be easily controlled by the operator by setting a toggle sleeve 83. Since the toggle sleeve 83 is fixed to the slider 82, the movement of the toggle sleeve 83 can drive the slider 82 to move. By fixing two anti-slip grooves 84 on the outside of the toggle sleeve 83, the operator's movement can be improved. To ensure the stability of the movable sleeve 83 and prevent it from slipping off the hand during use, a limiting ring 85 is fixed to the outside of the positioning sleeve 5, positioned above the slider 82. The limiting ring 85 limits the upward movement of the slider 82. Six through holes 86 arranged in a circular array are provided inside the positioning sleeve 5, allowing the installation of limiting balls 87. The diameter of the limiting balls 87 is greater than the depth of the through holes 86. A limiting groove 88 is provided on the outside of the pin 2, with its inner diameter matching the size of the limiting balls 87. When the pin 2 is inserted into the socket 1, the movable sleeve 83 causes the slider 82 to move downwards, compressing the spring 81. After the pin 2 enters the positioning sleeve 5, it will push the limiting ball 87 to move and slide in the through hole 86. When the bottom end of the pin 2 passes through the sealing washer 7 in the positioning sleeve 5 (in order to improve the quickness of the pin 2 passing through the sealing washer 7, grease can be applied to the outside of the pin 2 for lubrication), and contacts the top of the socket 1, the limiting groove 88 is flush with the through hole 86. At this time, the toggle sleeve 83 is released, and the slider 82 is reset by the spring force of the spring 81 and moves up to contact the limiting ring 85. When the slider 82 moves up, it will squeeze the limiting ball 87, so that the limiting ball 87 moves from the through hole 86 until it is stuck in the limiting groove 88 on the pin 2, so that the pin 2 is locked and fixed to the positioning sleeve 5 fixed on one side of the socket 1.
[0020] An anti-misinsertion mechanism 9 is installed between the socket 1 and the pin 2 to prevent incorrect insertion. This mechanism prevents incorrect insertion of the pin 2 into the socket 1, thus preventing damage. The anti-misinsertion mechanism 9 includes a positioning hole 91 at one end of the pin 2, with a positioning pin 92 inserted into the inner wall of the positioning hole 91 and fixed to one side of the socket 1. The inner wall of the positioning pin 92 has several insertion holes 93, with metal pins 94 inserted into the inner wall of each hole 93 and fixed to the inner wall of the positioning hole 91. A first semicircular block 95 is fixed to the inner wall of the positioning pin 92, and a second semicircular block 96 is fixed to the inner wall of the positioning hole 91. The first and second semicircular blocks 95 and 96 are aligned and connected to form a complete circle. The mechanism prevents incorrect insertion of the pin 2 into the socket 1. A positioning hole 91 is provided at one end, so that when the pin 2 is inserted into the socket 1, the positioning pin 92 on the socket 1 can be inserted into the positioning hole 91. The size of the positioning pin 92 matches the inner diameter of the positioning hole 91. After the positioning pin 92 is inserted into the positioning hole 91, several metal pins 94 in the positioning hole 91 are aligned and inserted into the corresponding sockets 93. If the pin 2 is not the correct one, it cannot be inserted into the socket 1 through the matching metal pins 94. At the same time, when the positioning pin 92 is inserted into the positioning hole 91, the first semicircular block 95 in the positioning pin 92 must be aligned with the second semicircular block 96 on the inner wall of the positioning hole 91 so that the first semicircular block 95 and the second semicircular block 96 are aligned and connected to form a complete circle. Only in this way can the correct pin 2 be perfectly inserted into the socket 1.
[0021] A base 10 is fixed to one side of the socket 1. The four corners of the base 10 are provided with mounting holes 11 for fixing with bolts. By setting the base 10, the socket 1 can be installed on electrical equipment, so that the electronic components in the socket 1 can be connected to the equipment. By setting the mounting holes 11, the socket 1 can be fixed by bolts and is easy to disassemble.
[0022] Working principle: When the operator connects the plug 2 and the socket 1, the sliding sleeve 83 moves the slider 82. The slider 82 compresses the spring 81, and after the plug 2 enters the positioning sleeve 5, it pushes the limiting ball 87 to move and slide within the through hole 86. When one end of the plug 2 passes through the sealing washer 7 inside the positioning sleeve 5 and contacts one side of the socket 1, the limiting groove 88 is flush with the through hole 86. At this time, the sliding sleeve 83 is released, and the slider 82 is reset by the elastic force of the spring 81. The slider 82 moves until it contacts the limiting ring 85. After the slider 82 moves, it compresses the limiting ball 87, causing the limiting ball 87 to slide out of the through hole 86. Move the pin 2 into the limiting groove 88 on the socket 1 until it is engaged with the positioning sleeve 5 fixed on one side of the socket 1. When the pin 2 is inserted into the positioning sleeve 5 and then into the socket 1, the pin 2 needs to be rotated so that the first semicircular block 95 in the positioning pin 92 on the socket 1 is aligned with the second semicircular block 96 in the positioning hole 91 of the pin 2. After the first semicircular block 95 and the second semicircular block 96 are aligned and connected, they form a complete circle. At the same time, the metal pin 94 in the positioning hole 91 is inserted into the corresponding socket 93. If the pin 2 is inserted into the socket 1 incorrectly, it will be impossible to connect with the socket 1.
