[0033] This embodiment relates to an aviation terminal crimping tool, see reference... Figures 1-9 The device includes a first clamp 10 and a second clamp 20 with their ends hinged together, and an adjustment assembly 30. The first clamp 10 or the second clamp 20 has multiple pressure head seats 21 distributed circumferentially, which cooperate to form a crimping interface 23 for crimping terminals. The adjustment assembly 30 is used to adjust the rotation angle of the first clamp 10 relative to the second clamp 20, thereby adjusting the closing size of the crimping interface 23.

[0034] In use, the rotation angle of the first clamp 10 relative to the second clamp 20 is adjusted by adjusting the component 30, thereby adjusting the sliding position of the pressure head seat 21, thus adjusting the size of the pressure interface 23, and enabling the pressing of terminals of different specifications and sizes.

[0035] In this embodiment, the first clamp body 10 and the second clamp body 20 respectively include a movable handle 101 and a fixed handle 201, and the number of pressure head seats 21 is four. When in use, the movable handle 101 is driven to rotate in a direction closer to or away from the fixed handle 201, which drives the four pressure head seats 21 to move in a direction closer to or away from each other, thereby realizing the adjustment of the closing size of the pressure interface 23, and thus enabling the pressing of terminals of different specifications and sizes.

[0036] Furthermore, the adjustment assembly 30 includes a movable piece 31 movably disposed on the second clamp 20, an eccentric shaft 32 rotatably disposed on the connecting piece, and an adjustment knob 33 sleeved on the eccentric shaft 32. One end of the movable piece 31 extends into the second clamp 20. The first clamp 10 is provided with a corresponding abutment groove 11 for the movable piece 31 to extend into and abut against the movable piece 31. The adjustment knob 33 is used to drive the eccentric shaft 32 to rotate, causing the movable piece 31 to slide towards or away from the abutment groove 11, so as to adjust the length of the movable piece 31 extending into the abutment groove 11.

[0037] The adjustment assembly 30, through the cooperation of the movable piece 31, the eccentric shaft 32, and the adjustment knob 33, adjusts the length of the movable piece 31 extending into the contact groove 11. This controls the rotation angle of the first clamp body 10 relative to the second clamp body 20, thereby adjusting the closure degree of the crimping interface 23. Specifically, the adjustment knob 33 drives the eccentric shaft 32 to rotate, which in turn causes the movable piece 31 to slide. The sliding direction and distance of the movable piece 31 determine the degree of closure of the crimping interface 23. This design also allows for more precise control of the crimping effect of the wire crimping pliers, adapting to terminals of different sizes and specifications.

[0038] Furthermore, the adjustment component 30 also includes a positioning block 34, which is rotatably mounted on the first clamp body 10. Its two ends are respectively provided with an abutment portion 341 and a toggle portion 342. The bottom of the movable piece 31 is provided with a first tooth groove 311 that abuts and engages with the abutment portion 341.

[0039] The movable piece 31 in the adjusting assembly 30 adjusts its length extending into the abutment groove 11 by rotating the eccentric shaft 32, thereby adjusting the closing size of the pressure port 23. The positioning stop 34 ensures that the bottom of the movable piece 31 abuts against the abutment part 341, further enhancing the stability and accuracy of the adjusting assembly 30. Specifically, the positioning stop 34 can be manually moved by the actuating part 342 to change its position, thereby adjusting the engagement state between the movable piece 31 and the abutment groove 11.

[0040] Furthermore, a waist-shaped groove 312 is provided through the movable piece 31, and a plurality of second tooth grooves 313 are provided on one of the long inner walls of the waist-shaped groove 312. A gear sleeve 321 is fixedly sleeved on the outside of the eccentric shaft 32, and a third tooth groove 322 that meshes with the first tooth groove 311 is provided on the outer periphery of the gear sleeve 321.

[0041] When the second toothed groove 313 on the inner wall of the waist-shaped groove 312 meshes with the third toothed groove 322 of the gear sleeve 321, the eccentric shaft 32 drives the gear sleeve 321 to rotate, thereby causing the movable piece 31 to slide along the waist-shaped groove 312. The sliding direction of the movable piece 31 (closer to or farther from the abutment groove 11) determines its length extending into the abutment groove 11, ultimately adjusting the rotation angle of the first clamp 10 relative to the second clamp 20 to adapt to the closing requirements of different specifications of the crimping interface 23.

[0042] Furthermore, the adjustment knob 33 includes a bottom cover 331 fixed relative to the second clamp body 20, an upper cover 332 rotatable relative to the bottom cover 331, a top cover 334 for closing the upper cover 332, and a locking block 333 for locking the rotation angle of the upper cover 332. The eccentric shaft 32 is fixedly connected to the upper cover 332. The inner wall of the bottom cover 331 is provided with a plurality of fourth tooth grooves 3311 in the circumferential direction. The upper cover 332 is provided with a locking groove 3321 for the locking block 333 to extend into. The locking block 333 includes a locking block 3331 for engaging the fourth tooth groove 3311.

[0043] The adjustment knob 33 is designed to adjust the eccentric shaft 32 by rotating the bottom cover 331 and the top cover 332 relative to each other, thereby indirectly adjusting the position of the movable piece 31. The inner wall of the bottom cover 331 has multiple fourth toothed grooves 3311, each corresponding to an adjustment position. After the locking block 3331 of the locking block 333 engages with the fourth toothed groove 3311, the rotation angle of the top cover 332 can be fixed, ensuring adjustment stability.

[0044] Furthermore, the locking block 333 includes a locking button 3332 and a locking spring 3333. The locking button 3332 is adapted to the locking groove 3321. The locking block 3331 is located below the locking button 3332 and is engaged in the fourth tooth groove 3311. One end of the locking spring 3333 abuts against the locking button 3332, and the other end abuts against the inner wall of the locking groove 3321.

[0045] By engaging the locking block 3331 into the fourth toothed groove 3311, the adjustment knob 33 is locked. One end of the locking spring 3333 abuts against the locking button 3332, and the other end abuts against the inner wall of the locking groove 3321, ensuring the reset function of the locking button 3332.

[0046] Furthermore, multiple pressure head seats 21 are slidably disposed on the second clamp body 20. The second clamp body 20 is provided with a pressure head groove 22 that slidably engages with the pressure head seat 21. The pressure head seat 21 is provided with a first guide post 211. The first clamp body 10 is provided with a first guide groove 12 that slidably engages with the first guide post 211.

[0047] The pressure head seat 21 slides into the first guide groove 12 on the first clamp body 10 via the first guide post 211. This engagement ensures that the pressure head seat 21 maintains stable and precise positioning during sliding, thereby preventing the terminal from shifting or loosening during crimping. Furthermore, the pressure head groove 22 provides a stable sliding track, allowing the pressure head seat 21 to slide smoothly on the second clamp body 20.

[0048] Furthermore, the first clamp body 10 is provided with at least two second guide posts 13, and the second clamp body 20 is provided with a second guide groove 24 for sliding cooperation with the second guide posts 13.

[0049] At least two second guide posts 13 are provided on the first clamp body 10, which slide in cooperation with the second guide groove 24 on the second clamp body 20, so that the first clamp body 10 and the second clamp body 20 can maintain good alignment and stability during the crimping process.

[0050] It should be noted that the fit between the first guide post 211 and the first guide groove 12, and between the second guide post 13 and the second guide groove 24, can be adjusted according to actual needs. For example, the guide post can be cylindrical or rectangular in cross-section, and the guide groove can be designed as a straight line or an arc to ensure sliding stability.

[0051] Furthermore, the crimping pliers proposed in this application also include an accessory 40, which includes a guide sleeve 41 installed below the crimping interface 23 and a nut 42 screwed onto the outside of the guide sleeve 41. The side wall of the guide sleeve 41 is provided with a plurality of fixing grooves 411 communicating with the inside of the guide sleeve 41. A slider 412 is slidably arranged in the fixing groove 411. The outer thickness of the slider 412 gradually decreases from the direction close to the crimping interface 23 to the direction away from the crimping interface 23, and a clamping block 413 for fixing the terminal is provided on the inner side of the slider 412.

[0052] Furthermore, Annex 40 also includes an abutment rod 43 movably disposed at the bottom of the guide sleeve 41. The abutment rod 43 is used to contact the end of the terminal. The length of the abutment rod 43 extending into the guide sleeve 41 is adjusted by a threaded screw-on snap-fit ​​structure to adapt to the pressing requirements of terminals of different lengths.

[0053] In use, the terminal is inserted from the top of the crimping interface 23, with the bottom end of the terminal abutting against the abutment rod 43. By rotating the nut 42, multiple sliders 412 move simultaneously toward each other, thus accommodating terminals of different sizes and allowing adjustment of the terminal crimping position. Furthermore, by adjusting the length of the abutment rod 43 extending into the guide sleeve 41, terminals of different lengths can be crimped, further expanding the applicability of the crimping pliers.

[0054] The above is only used to illustrate the technical solution of this utility model and not to limit it.
