[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] Embodiment: The utility model provides a pin-and-socket connector, such as Figures 1 to 7As shown, it includes a connector 1 and a pin 2. A buffer groove is provided inside the connector 1. A plurality of sliding grooves 3 are evenly distributed on the inner wall of the buffer groove. Magnet sliders 4 are slidably inserted in the plurality of sliding grooves 3. Sliding grooves 2 5 are provided on both sides of the buffer groove. A sliding block 6 is slidably connected between the two sliding grooves 2 5. A spring 1 7 is fixedly connected between the sliding block 6 and the buffer groove. A magnet 8 is fixedly connected to the outer wall of the sliding block 6 near one end of the pin 2. The magnet 8 is in the shape of a ring magnet. When in use, the user first inserts the pin 2 into the socket hole, and the pin 2 is pressed downward to drive the sliding block 6 to move downward in the sliding groove 3. At this time, the sliding block 6 squeezes the spring 1 7 when moving downward, and the sliding block 6 squeezes the lower magnet slider 4 into the sliding groove 2 5 while moving downward. At this time, the sliding block 6 drives the magnet in the process of descending. 8 descends, and the magnet 8, while descending, sucks the upper magnet slider 4 out of the sliding groove 2 5 by magnetic force, preventing the internal circuit board welding part from being desoldered when the pin 2 is inserted into the socket hole, and producing a buffering effect. When the pin 2 needs to be pulled out, the pin 2 drives the sliding block 6 upward and guides it to move upward in the sliding groove 3. The sliding block 6 stretches the spring 7 when moving upward, and drives the magnet 8 to rise at the same time. When the sliding block 6 and the magnet 8 rise synchronously, the magnet 8 adsorbs the magnet slider 4, so that when the sliding block 6 rises, the magnet slider 4 blocks the impact force of the sliding block 6 when it rises, so that the impact force is effectively buffered, and the magnet slider 4 is squeezed back into the sliding groove 2 5 when it rises, so that the user provides a buffering effect when plugging and unplugging, avoids the desoldering of the socket circuit board welding part, and enhances the comfort of plugging and unplugging.

[0022] A sliding plate 12 is slidably connected inside the sliding block 6, and a rubber pad is fixedly connected to the outer wall of the sliding plate 12. The rubber pad can protect the fixing rod 13 from damage caused by long-term wear. A spring 11 is fixedly connected between the sliding plate 12 and the inside of the sliding block 6. Corresponding grooves 9 are symmetrically opened on the inner wall of the sliding block 6. A card slot 10 is symmetrically opened on the inner wall of the sliding block 6 close to the sliding plate 12. The two card slots 10 are connected to the corresponding grooves 9. A fixing rod 13 is arranged inside the sliding block 6. Fixed blocks 14 are fixedly connected to both ends of one side of the fixing rod 13. The outer wall of the other side of the fixing rod 13 is threadedly connected with a pin 2. When the user needs to replace the pin 2 of different lengths, the pin 2 and the fixing rod 1 3 is separated, and then the pins 2 of different lengths are replaced. The fixing block 14 has the same diameter as the corresponding slot 9, and the fixing block 14 has the same size as the card slot 10. When in use, when the pin 2 needs to be fixed, the fixing block 14 is aligned with the corresponding slot 9 through the fixing rod 13 to insert it inside, and then the sliding plate 12 is squeezed by the spring 2 11. When the fixing block 14 moves to the bottom inside the corresponding slot 9, the fixing rod 13 is rotated, and when the fixing block 14 corresponds to the card slot 10, the sliding plate 12 is pushed by the elastic force of the spring 2 11. The sliding plate 12 engages the moving fixing block 14 with the card slot 10, and fixes the fixing rod 13 and the pin 2 to prevent the pin 2 from loosening when connected to the socket.

[0023] Working principle: when in use, when the pin 2 needs to be fixed, the fixing block 14 is aligned with the corresponding slot 9 through the fixing rod 13 and inserted into the inside, and then the sliding plate 12 is squeezed by the spring 2 11. When the fixing block 14 moves to the bottom inside the corresponding slot 9, the fixing rod 13 is rotated again. When the fixing block 14 corresponds to the card slot 10, the sliding plate 12 is pushed by the elastic force of the spring 2 11. The sliding plate 12 engages the moving fixing block 14 with the card slot 10, and fixes the fixing rod 13 and the pin 2 to prevent the pin 2 from loosening when connected to the socket. When the user first inserts the pin 2 into the socket hole, the pin 2 is pressed down to drive the sliding block 6 to move downward in the sliding slot 3. At this time, the sliding block 6 squeezes the spring 1 7 when moving downward, and the sliding block 6 squeezes the lower magnet slider 4 into the sliding slot 2 5 while moving downward. At this time, the sliding block 6 During the descending process, the magnet 8 is driven to descend. While the magnet 8 is descending, the upper magnet slider 4 is sucked out of the sliding groove 2 5 by magnetic force, so as to prevent the internal circuit board welding part from being desoldered when the pin 2 is inserted into the socket hole, thereby producing a buffering effect. When the pin 2 needs to be pulled out, the pin 2 drives the sliding block 6 upward and guides it to move upward in the sliding groove 1 3. When the sliding block 6 moves upward, it stretches the spring 1 7 and drives the magnet 8 to rise at the same time. When the sliding block 6 and the magnet 8 rise synchronously, the magnet 8 adsorbs the magnet slider 4, so that when the sliding block 6 rises, the magnet slider 4 blocks the impact force of the sliding block 6 when it rises, so that the impact force is effectively buffered, and the magnet slider 4 is squeezed back into the sliding groove 2 5 when it rises, so that the user can get a buffering effect when plugging and unplugging, avoid desoldering of the socket circuit board welding part, and enhance the comfort of plugging and unplugging.

[0024] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
