Description

Technical Field

[0001] The utility model relates to a terminal, in particular to a terminal with a structure for preventing a plastic shell from swinging up and down, and belongs to the technical field of wire connection. Background Art

[0002] The existing plug connector has the following disadvantages: after the terminal is inserted into the jack, it swings up and down greatly, which not only reduces the contact reliability between the terminal and the insulator, but also makes it easy to pull the terminal out of the jack.

[0003] Chinese patent application number: CN201120254578.1 discloses a plug connector, which includes an insulating body and a jack for inserting a terminal on the insulating body, the jack includes a first inner wall surface and a second inner wall surface opposite to each other, a first guide groove matching with a terminal elastic contact piece near the insertion end of the jack and a through hole near the rear end of the jack are provided on the first inner wall surface, a second guide groove matching with a terminal positioning part is provided on the second inner wall surface; corresponding positioning convex strips are provided on the two opposite side walls of the second guide groove. The small up and down swing of the terminal after insertion not only improves the reliability of the contact between the terminal and the copper pin of the needle seat, but also makes it difficult to pull the terminal out of the jack.

[0004] When the terminal needs to be pulled out, the patent requires manual force to separate it. If the staff uses improper force, the connection between the terminal and the insulator may be damaged, thereby reducing the service life of the terminal. Therefore, we propose a terminal with a structure to prevent the rubber shell from swinging up and down. Utility Model Content

The bottom of the terminal body 1 is fixedly connected with a positioning part 4, and a clamping assembly 5 is arranged inside the positioning part 4. The clamping assembly 5 includes two slide bars 51. The two slide bars 51 are slidably installed inside the positioning part 4. The ends of the two slide bars 51 that are close to each other are fixedly connected with a trapezoidal block 52. The internal thread of the positioning part 4 is connected with a screw rod 56. The bottom ends of the screw rod 56 are respectively in contact with the surfaces of the two trapezoidal blocks 52. The ends of the two slide bars 51 that are away from the trapezoidal blocks 52 extend to the outside of the positioning part 4 and are fixedly connected with a clamping block 54. A groove 7 is provided inside the insulating body 6. Two grooves 8 are symmetrically provided inside the insulating body 6. One side of the two grooves 8 is connected with the groove 7.

[0023] During operation, the forward screw 56 moves to the right while squeezing the trapezoidal block 52, so that the two trapezoidal blocks 52 move to both sides, the two trapezoidal blocks 52 drive the slide rod 51 to slide, and the two slide rods 51 drive the clamping block 54 to move, so that the two clamping blocks 54 extend to the inside of the corresponding groove 2 8, thereby realizing the clamping connection between the positioning part 4 and the insulating body 6.

[0024] Furthermore, one end of the terminal body 1 and the positioning portion 4 are in contact with the interior of the groove 1 7 , and the two clamping blocks 54 are in contact with the interiors of the two grooves 2 8 respectively.

[0025] Furthermore, the outer walls of the two slide bars 51 are sleeved with springs 53 , and the two ends of the two springs 53 are respectively fixedly connected to the inside of the positioning portion 4 and one side of the trapezoidal block 52 .

[0026] Furthermore, one end of the screw rod 56 away from the trapezoidal block 52 extends to the outside of the positioning portion 4 , and a nut 55 is threadedly connected to the outer wall of the screw rod 56 , and one side of the nut 55 contacts the surface of the insulating body 6 .

[0027] During operation, the screw rod 56 is locked by rotating the nut 55 .

[0028] Furthermore, the outer wall of the terminal body 1 and the outer wall of the positioning portion 4 are both fixedly connected with elastic contact pieces 2, and the inner walls of the two elastic contact pieces 2 are respectively fixedly connected with springs 1 3 between the terminal body 1 and the positioning portion 4.

[0029] During operation, the elastic contact piece 2 is squeezed by the groove 7, and the elastic contact piece 2 squeezes the spring 3, thereby increasing the internal friction between the terminal body 1 and the insulating body 6, improving the connectivity between the terminal body 1 and the insulating body 6, and preventing the terminal body 1 from shaking due to the up and down movement of the rubber shell.

[0030] Furthermore, the terminal body 1 and the insulating body 6 are detachably connected.

[0031] Working principle: First, insert one end of the terminal body 1 into the interior of the insulating body 6. At this time, the groove 7 squeezes the elastic contact piece 2, and the elastic contact piece 2 squeezes the spring 3, increasing the internal friction between the terminal body 1 and the insulating body 6, improving the connectivity between the terminal body 1 and the insulating body 6, and preventing the terminal body 1 from shaking due to the up and down movement of the rubber shell. Then, the screw rod 56 is rotated forward, and the screw rod 56 moves to the right while squeezing the trapezoidal block 52, so that the two trapezoidal blocks 52 move to both sides, and the two trapezoidal blocks 52 drive the slide bar 51 to slide, and the two slide bars 51 drive the block 54 to move. The two blocks 54 are moved so that they extend to the inside of the corresponding groove 8, thereby realizing the engagement connection between the positioning portion 4 and the insulating body 6. The nut 55 is then rotated to lock the screw 56. When the terminal body 1 needs to be pulled out of the insulating body 6, the nut 55 is rotated in the opposite direction, and then the screw 56 is rotated in the opposite direction. The screw 56 moves to the left. At this time, the two trapezoidal blocks 52 are moved closer to each other by the elastic force of the spring 53, so that the two blocks 54 are away from the groove 8. The terminal body 1 is then pulled out, thereby realizing the separation of the terminal body 1 from the insulating body 6.
