[0003] The contact assembly is composed of a pin contact and a socket contact that match each other. When in use, one of the pin contact and the socket contact is assembled in the plug housing, and the other is assembled in the socket housing. With the plug and socket being plugged in and out, the contact assembly completes the conduction and disconnection of the circuit. In a traditional contact assembly, the socket is generally composed of a conductive metal sleeve, and the pin is composed of a conductive metal rod. When plugged in, the pin is inserted into the inner hole of the socket and contacts with the socket, thereby completing the conduction of the circuit.

[0004] However, the length of the pin of the existing connector jack structure is fixed, and the length of the pin cannot be adjusted according to usage requirements. Utility Model Content

[0009] As a preferred embodiment of the above technical solution, the two clamping blocks are in contact with each other, and semicircular grooves are provided in the middle of the opposite surfaces of the two clamping blocks. The diameter of the semicircular grooves is consistent with that of the pins, and the semicircular grooves are in contact with the surfaces of the pins.

[0010] As a preferred embodiment of the above technical solution, a second spring is fixedly connected between the opposite sides of the two clamping blocks and the inner wall of the socket body, and an L-shaped frame is fixedly connected to the top end of the left clamping block and one side of the bottom end of the right clamping block.

[0021] 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.

[0022] Embodiment: The utility model provides a connector jack structure, such as Figures 1 to 3 As shown, it includes a jack body 1 and a pin 2. One side of the jack body 1 is rotatably connected to a connecting block 3, the pin 2 is inserted into the connecting block 3, the jack body 1 is connected to the connecting block 3, and a plurality of positioning holes 4 are provided on both sides of one end of the pin 2 close to the jack body 1, and are equidistantly arranged. A positioning mechanism is arranged inside the jack body 1, and the pin 2 after the length is adjusted can be fixed through the positioning mechanism.

[0023] like Figure 4 As shown, the positioning mechanism includes: a positioning block 8, a fixing block 5 is fixedly connected to both sides of the inner wall of the jack body 1, and each fixing block 5 is connected to both sides of the inner wall with a first slide groove 6, and each first slide groove 6 is slidably connected to the inside of the slide block 7, and the slide block 7 can move through the first slide groove 6, and the positioning block 8 is fixedly installed on the slide block 7, and a first spring (not marked in the figure) is fixedly connected between one side of the positioning block 8 and the inner wall of the fixing block 5, and the positioning block 8 and the positioning hole 4 are engaged with each other. When it is necessary to adjust the length of the pin 2, the pin 2 is pulled outward. At this time, the pin 2 will squeeze the positioning blocks 8 on both sides, and the positioning block 8 will move backward after being squeezed by the arc surface, so that it will no longer be engaged with the positioning hole 4. After the pin 2 is adjusted to a suitable length, the positioning block 8 is pushed to reset by the reaction force of the first spring, and then engaged with the positioning hole 4, so that the pin 2 is fixed again.

[0024] like Figures 5 to 6As shown, a transverse plate 10 is fixedly connected inside the jack body 1 and between the connecting block 3 and the fixing block 5, second slide grooves 11 are provided on both sides of the top of the transverse plate 10, and clamping blocks 12 are slidably connected on both sides of the two second slide grooves 11, and the clamping blocks 12 can move through the second slide grooves 11, and the two clamping blocks 12 are in contact with each other, and semicircular grooves are provided in the middle of the opposite surfaces of the two clamping blocks 12, and the diameter of the semicircular grooves is consistent with that of the plug pin 2, and the semicircular grooves are in contact with the surface of the plug pin 2, and the plug pin 2 is clamped and fixed by the two clamping blocks 12, and a second spring 13 is fixedly connected between the opposite surfaces of the two clamping blocks 12 and the inner wall of the jack body 1, and an L-shaped frame 14 is fixedly connected to the top of the left clamping block 12 and one side of the bottom end of the right clamping block 12, and the two L The opposite surfaces of the L-shaped frame 14 are set as arc surfaces, and the two ends of the connecting block 3 close to the jack body 1 are fixedly connected with arc blocks 15. The two arc blocks 15 are set up and down, and one side of the arc block 15 contacts the arc surface of the L-shaped frame 14. When the length of the pin 2 needs to be adjusted, the connecting block 3 is first rotated to the left. At this time, the connecting block 3 drives the two arc blocks 15 to rotate and squeeze the two L-shaped frames 14. Through the setting of the arc surface, the two L-shaped frames 14 drive the two clamping blocks 12 at the bottom to move toward the opposite side. At this time, the two clamping blocks 12 release the fixation of the pin 2. After the adjustment is completed, the connecting block 3 is released and the reaction of the second spring 13 pushes the two clamping blocks 12 to move toward the opposite side, and then the pin 2 is clamped and fixed again.

[0025] Working principle: when it is necessary to adjust the length of the pin 2, first rotate the connecting block 3 to the left, at this time the connecting block 3 drives the two arc blocks 15 to rotate and squeeze the two L-shaped frames 14, and the two L-shaped frames 14 drive the two clamping blocks 12 at the bottom to move toward the opposite side through the setting of the arc surface, at this time the two clamping blocks 12 release the fixation of the pin 2 and pull the pin 2 outward, at this time the pin 2 will squeeze the positioning blocks 8 on both sides, and the positioning blocks 8 will move backward after being squeezed by the arc surface, so that they will no longer engage with the positioning hole 4, after the pin 2 is adjusted to the appropriate length, the positioning block 8 is pushed to reset by the reaction force of the first spring, and then engages with the positioning hole 4, and then the connecting block 3 is released and the reaction of the second spring 13 pushes the two clamping blocks 12 to move toward the opposite side, and then the pin 2 is clamped and fixed again.
