[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0036] Reference Figure 1-8 , an embodiment provided by the utility model:
[0037] A multifunctional high and low voltage connector, comprising a first protective head 1 and a second protective head 3, wherein a wire 2 is fixedly connected between the first protective head 1 and the second protective head 3, a protective mechanism 4 is arranged inside the first protective head 1, and the protective mechanism 4 comprises a plurality of fixed columns 401, a plurality of positioning columns 402, a protective sleeve 403, a plurality of clamping blocks 404, a plurality of pressing blocks 405, a plurality of compression springs 406, a plurality of rotating blocks 407, a plurality of limiting grooves 408 and a plurality of fixed blocks 409, wherein the internal thread of the protective sleeve 403 is connected to the outside of the first protective head 1, a plurality of clamping blocks 404 are fixedly arranged on one side of the first protective head 1, a plurality of compression springs 406 are fixedly arranged at opposite ends in pairs in the first protective head 1, and a plurality of pressing blocks 405 are slidably arranged at opposite ends in pairs in pairs. Inside a protective head 1, opposite ends of multiple compression springs 406 are fixedly arranged on opposite ends of multiple rotating blocks 407, the outsides of multiple rotating blocks 407 are rotatably arranged inside the first protective head 1, one side of multiple rotating blocks 407 are rotatably arranged on one side of multiple fixed blocks 409, and the other sides of multiple rotating blocks 407 are rotatably arranged on one side of multiple pressing blocks 405, multiple limiting grooves 408 are respectively opened on one side of multiple fixed columns 401, and the outsides of multiple fixed blocks 409 are slidably arranged inside the first protective head 1, one side of multiple fixed columns 401 are fixedly arranged on one side of the first protective head 1 away from the multiple pressing blocks 405, and one side of multiple positioning columns 402 are fixedly arranged on one side of the first protective head 1 away from the multiple pressing blocks 405;
[0038] When the first protective head 1 is connected to the second protective head 3, the block 404 and the positioning column 402 on the first protective head 1 are accurately embedded in the pre-designed slot 502 and the positioning slot 503 inside the second protective head 3, ensuring the directionality and accuracy of the connection. When the slider 501 contacts the first protective head 1, it will apply pressure to the fixed block 409, causing the compression spring 406 under the fixed block 409 to be compressed. When the slider 501 continues to slide to the predetermined position, the compressed compression spring 406 will use its own elastic potential energy to drive the fixed block 409 to reset, and make it firmly engaged in the groove 508 at the bottom of the slider 501, thereby forming a clamping connection. At the same time, the slider 501 moves with the connection. The action gradually moves into the fixed column 401, and the fixed column 401 generates pressure on the limit block 505 inside the slider 501, which also triggers the spring 507 associated with the limit block 505 to contract until the slider 501 is in place, and the spring 507 returns to its original state, pushing the limit block 505 to fit tightly into the limit groove 408 inside the fixed column 401, thereby achieving double locking, ensuring that the connector will not be easily separated when subjected to force, so that the connection process has a self-locking function, and the accuracy and stability of the connection are improved. When the connection is completed, the protective sleeve 403 is connected to the outside of the first protective head 1 through a threaded connection, providing good sealing and stability. The wire 2 is spirally shaped to meet the usage requirements of different lengths.
[0039] A connecting mechanism 5 is provided inside the second protective head 3, and the connecting mechanism 5 includes a plurality of sliders 501, a plurality of slots 502, a plurality of positioning slots 503, a plurality of rotating blocks 504, a plurality of limiting blocks 505, a plurality of connecting blocks 506, a plurality of springs 507, a plurality of grooves 508 and a plurality of mounting blocks 509. The plurality of sliders 501 are slidably arranged on the outside of the second protective head 3 at opposite ends in pairs, the plurality of rotating blocks 504 are respectively rotatably arranged on the other side of the plurality of mounting blocks 509 at one side, the plurality of mounting blocks 509 are fixedly arranged on the outside of the second protective head 3 at opposite ends in pairs, the plurality of rotating blocks 504 are respectively rotatably arranged on the side of the plurality of sliders 501 away from the plurality of mounting blocks 509 at the other side, and the plurality of grooves 508 are respectively opened on the plurality of sliders at opposite ends in pairs. 501 lower end, multiple springs 507 are fixedly arranged in the multiple sliders 501 at opposite ends in pairs, multiple springs 507 are fixedly arranged in the multiple sliders 501 at opposite ends in pairs, multiple limit blocks 505 are fixedly arranged in the multiple connecting blocks 506 at opposite ends in pairs, multiple limit blocks 505 are slidably arranged in the sliders 501 at the outside, multiple connecting blocks 506 are slidably arranged in the sliders 501 at the outside, multiple positioning grooves 503 are arranged in the second protective head 3 on one side, multiple card slots 502 are arranged in the second protective head 3 on one side, an inner core 7 is fixedly arranged in the second protective head 3, and a sealing ring 6 is fixedly arranged on the side of the second protective head 3 close to the first protective head 1;
[0040] When connecting the first protective head 1 with the second protective head 3, the rotating block 504 fixed to the mounting block 509 is manually operated to cause the slider 501 to move smoothly along the outside of the first protective head 1 and the second protective head 3, so that the fixing column 401 enters the inside of the slider 501 and squeezes the limiting block 505 to force the spring 507 to contract. When reaching the appropriate position, the limiting block 505 will snap into the limiting groove 408 inside the fixing column 401. At the same time, the fixing block 409 will snap into the groove 508 inside the slider 501, so that the connection is stable, which can not only realize the effective docking of the conductive contacts, but also can ensure the stability under vibration. When moving and pulling, it maintains stable contact to prevent power outages. Finally, the protective sleeve 403 is threadedly connected to the mounting block 509 and tightened by rotating it, thereby providing additional stability protection for the outside and ensuring that the multifunctional high and low voltage connector can maintain stable, safe and efficient operation in various environments. The inner core 7 is the core component for realizing high and low voltage conversion, and carries the functions of conduction and signal transmission. When the second protective head 3 is connected to the first protective head 1, the sealing ring 6 will be squeezed, so that the sealing ring 6 ensures the sealing of the connector docking surface, prevents the entry of moisture and dust, and enhances the durability and safety of the connector in complex environments.
[0041] Working principle: When in use, the first protective head 1 is connected to the second protective head 3, and the connection stability of the connector is enhanced by the protective mechanism 4 inside the first protective head 1 and the connecting mechanism 5 inside the second protective head 3. The card block 404 and the positioning column 402 on one side of the first protective head 1 are connected with the card slot 502 and the positioning slot 503 inside the second protective head 3, and then the rotating block 504 connected to the mounting block 509 is pushed to make the slider 501 slide outside the first protective head 1 and the second protective head 3. When the slider 501 reaches the outside of the first protective head 1, it squeezes the fixed block 409 to shrink the compression spring 406 at its lower end. When the slider 501 slides to the preset position, the compression spring 406 is acted on by the elastic force to make the fixed block 409 rebounds and is engaged in the groove 508 at the lower end of the slider 501, and the slider 501 slides into the fixed column 401, so that the fixed column 401 squeezes the limit block 505 inside the slider 501, and the spring 507 contracts. When the slider 501 slides to the final position, the spring 507 rebounds and moves the limit block 505 to the limit groove 408 inside the fixed column 401, and then the clamping and fixing are achieved. When the first protective head 1 and the second protective head 3 are connected, the sealing ring 6 is squeezed to improve the overall sealing. Finally, the protective sleeve 403 is threadedly connected to the mounting block 509, thereby providing good stability for the outside of the first protective head 1 and the second protective head 3.
[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
