Abstract

The present invention relates to the technical field of the production of high and low voltage distribution cabinets, and specifically relates to a crimping device for wiring terminals of high and low voltage distribution cabinets, which includes a base. An inverted U-shaped bracket is fixedly installed on the upper end surface of the base, and a number of operating plates located inside the inverted U-shaped bracket and arranged in a linear array are provided. A crimping mechanism is jointly arranged on the inverted U-shaped bracket and the base. An integrated operation model of positioning, fixing, and crimping is adopted to complete the synchronous crimping operation of multiple wiring terminals. Before crimping, the wiring terminals are double-limited and the cables are clamped and fixed to ensure the stable positions of the wiring terminals and the cables during the crimping process, achieve uniform force application, and ensure that each wiring terminal is correctly and stably crimped. This not only improves the stability of the connection of the wiring terminals and the crimping quality, enhances the electrical performance and mechanical strength, but also maximizes the contact area to reduce the contact resistance and improve the conduction efficiency, so as to ensure the reliability, safety of the electrical connection and the overall performance of the system.

Description

Technical Field

[0001] The present invention relates to the technical field of the production of high and low voltage distribution cabinets, and particularly to a crimping device for the wiring terminals of high and low voltage distribution cabinets. Background Art

[0002] The wiring terminals of high and low voltage distribution cabinets are components used to connect wires in the distribution cabinets. They allow the cables to establish electrical connections with the electrical equipment inside the distribution cabinets and mainly play important connection and fixing roles in the electrical system. These wiring terminals are usually made of metal and are wrapped with insulating materials to ensure their safety and prevent short circuits. In order to maximize the contact area between the cable and the wiring terminal, it is necessary to perform a crimping operation on the wiring terminal and the cable to reduce the contact resistance, energy loss, and heat generation, thereby ensuring the reliability, safety, and overall performance of the electrical connection.

[0003] Currently, there are the following disadvantages when crimping the wiring terminals of high and low voltage distribution cabinets: 1. When crimping the wiring terminals, it is usually necessary to put the wiring terminal on the front end of the cable and send it into the crimping machine, and then perform a crimping operation on it through the crimping machine, and take it out after the crimping is completed to perform the crimping of the next wiring terminal. However, during the process of crimping the wiring terminal, the wiring terminal and the cable are not limited and fixed, so the wiring terminal and the cable will shift during the crimping process, which will affect the crimping quality and cause unstable electrical connections. Moreover, only one wiring terminal can be processed individually each time, and the working efficiency is low; 2. During the process of crimping the wiring terminals, due to the change of the positions of the wiring terminal and the cable or the operator's operation error, there will be a gap between the front end of the wiring terminal and the cable, resulting in a reduction in the contact area between the cable and the wiring terminal, an increase in the contact resistance, and poor contact. At the same time, local overheating may occur at the place with poor contact, affecting the service life of the equipment, and the stability and reliability of the electrical connection will also be affected.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The terminal crimping device for high and low voltage distribution cabinets, through the coordinated use of the crimping mechanism, the end fixing mechanism and the line fixing mechanism, adopts an integrated operation model of positioning, fixing and crimping to complete the synchronous crimping operation of multiple terminals. Before crimping, the terminal is doubly limited and the cable is clamped and fixed to ensure the stable position of the terminal and the cable during the crimping process, to achieve uniform force, to ensure that each terminal is correctly and stably crimped, which not only improves the stability of the terminal connection and the crimping quality, but also reduces the adjustment time, and enhances the electrical performance and mechanical strength. At the same time, the contact area is maximized to reduce the contact resistance, improve the conductive efficiency, and ensure the reliability and safety of the electrical connection and the overall performance of the system.

[0017] 2. The terminal crimping device for the high and low voltage distribution cabinet, through the coordinated use of the crimping mechanism and the fixed end mechanism, double limits the inner ring and the screw hole position of the terminal before crimping, ensuring that the terminal remains fixed during the crimping process, thereby improving the stability of the terminal connection, reducing the time for re-adjusting the terminal position, and improving the efficiency of the crimping work.

[0018] 3. The crimping device for the terminal blocks of the high and low voltage distribution cabinets clamps and fixes the cables before crimping through the coordinated use of the crimping mechanism and the line fixing mechanism, ensuring that the cables will not shift during the crimping process. At the same time, it ensures that the cables can be evenly stressed during crimping, thereby improving the quality of crimping and ensuring that the connection after crimping is more firm and reliable. In the process of fixing, the cables are pushed into the terminal blocks to maximize the contact area between the cables and the terminal blocks, thereby reducing contact resistance and improving conductive efficiency.

[0019] 4. The terminal crimping device for the high and low voltage distribution cabinet fixes the terminal and the cable on the same horizontal plane at the same time through the coordinated use of the terminal fixing mechanism and the line fixing mechanism, ensuring uniform distribution of force during crimping and avoiding poor connection due to uneven pressure. Uniform crimping can ensure closer contact between the cable and the terminal, thereby improving the electrical performance and mechanical strength of the connection.

[0032] Please refer to Figure 1 and Figure 2 The driving portion 41 includes a hydraulic cylinder 411, a connecting cross plate 412, and a connecting column 413. A hydraulic cylinder 411 with a telescopic end penetrating its lower end face is fixedly installed on the upper end face of the U-shaped bracket 2. The telescopic end of the hydraulic cylinder 411 is fixedly installed with a connecting cross plate 412. On the lower end face of the connecting cross plate 412, connecting columns 413 corresponding to the operation panel 3 are fixedly installed.

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The execution portion 42 includes a limiting sliding column 421, a moving seat 422, an upper pressing die 423, a lower pressing die 424, and an extrusion column 425. On the upper end face of the operation panel 3, symmetrically arranged limiting sliding columns 421 are fixedly installed. On the symmetrically arranged limiting sliding columns 421, a moving seat 422 fixedly connected to the corresponding connecting column 413 is slidably installed.

[0034] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5The matching part 51 includes a matching cylinder 511, a placement plate 512, a limiting groove 513, a circular slide plate 514, a matching column 515 and a hinged rod 516. The upper end surface of the operating panel 3 is fixedly installed with a matching cylinder 511 located directly below the extrusion column 425. The placement plate 512 is fixedly sleeved on the outer ring wall of the matching cylinder 511. The limiting groove 513, which is located below the placement plate 512 and is symmetrical on the left and right, is penetrated through the outer ring wall of the matching cylinder 511. A circular slide plate 514 is slidably installed in the matching cylinder 511 through a set spring. A matching column 515 matching with the extrusion column 425 is fixedly installed at the center of the upper end surface of the circular slide plate 514. A hinged rod 516, which is symmetrical on the left and right and located in the corresponding limiting groove 513, is hinged on the circular slide plate 514. The hinged rod 516 is movably connected to the corresponding limiting groove 513.

[0035] During specific work, when it is necessary to crimp the terminals of the high and low voltage distribution cabinets, first put the terminals on the front end of the cable, and then put the terminals on the outside of the matching tube 511. At this time, the matching tube 511 will limit the inner ring part of the terminals, so that the terminals can be placed flat on the placement plate 512, and the position of the terminals to be crimped is in the lower die 424, and then repeat to complete the placement of multiple subsequent terminals.

[0036] When it is necessary to crimp the terminal, the hydraulic pump (not shown in the figure) fixedly installed on the base 1 is started to make the hydraulic cylinder 411 descend with the connecting cross plate 412, and the connecting cross plate 412 will drive the movable seat 422 to descend through the connecting column 413, so that the upper pressing die 423 approaches the lower pressing die 424 until the upper pressing die 423 and the lower pressing die 424 cooperate to complete the crimping operation of the terminal, and then the hydraulic cylinder 411 can be started in the reverse direction to return the connecting cross plate 412 to its original position.

[0037] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The connecting part 52 includes a first limiting slide rail 521, a first slider 522 and a support arm 523. The first limiting slide rail 521 is fixedly installed on the placement plate 512, and a supporting diagonal rod is arranged between the first limiting slide rail 521 and the matching tube 511. The first slider 522 hinged to the corresponding hinge rod 516 is slidably installed in the first limiting slide rail 521, and a support arm 523 is fixedly installed on the first slider 522.

[0038] See also Figure 1 and Figure 5The straightening part 53 includes a slide rod 531, an alignment plate 532 and a fixed plate 533. Two slide rods 531 distributed up and down are slidably installed on the support arm 523. A spring sleeved on the slide rod 531 is fixedly installed on one side wall of the left and right symmetrical support arms 523 on the same operating panel 3 that are away from each other. A fixing plate 533 fixedly connected to the corresponding two spring slide rods 531 is fixedly installed on one end of the spring away from the corresponding support arm 523, and an alignment plate 532 is fixedly installed on the other ends of the two spring slide rods 531.

[0039] See also Figure 1 , Figure 3 and Figure 5 The limiting part 54 includes an insert rod 541 and a limiting rod 542. The insert rod 541 is fixedly installed on a side wall where the front ends of the left and right symmetrical support arms 523 on the same operating panel 3 are close to each other. The limiting rod 542 is fixedly installed on the right end face of the insert rod 541 on the left side, and the insert rod 541 on the right side is provided with a limiting hole that cooperates with the limiting rod 542.

[0040] During specific operation, when the moving seat 422 descends, it will first contact the matching column 515 through the extrusion column 425 and drive the circular slide plate 514 to descend. At this time, the hinged rods 516 on both sides will pull the first sliders 522 on both sides toward the wiring terminal synchronously under the action of the downward pulling force of the circular slide plate 514, and the first slider 522 will bring the corresponding support arm 523 closer to the wiring terminal.

[0041] When the support arms 523 on both sides approach the terminal, the two sliding rods 531 distributed up and down on both sides will squeeze the front end of the terminal through the alignment plate 532 under the action of the spring, and the synchronous squeezing of the alignment plates 532 on both sides will straighten the position of the terminal, so that the screw hole of the terminal corresponds to the insertion rod 541, and then the moving seat 422 continues to descend to make the support arms 523 on both sides continue to approach the terminal, so that the insertion rod 541 can be inserted into the screw hole of the terminal, and at the same time, the limiting rod 542 will also be inserted into the limiting hole, so as to complete the limitation of the screw hole position of the terminal, and by doubly limiting the inner ring and the screw hole position of the terminal before crimping, it is ensured that the terminal always remains fixed during the crimping process of the crimping mechanism 4, thereby improving the stability of the terminal connection.

[0042] When the movable seat 422 rises after the crimping mechanism 4 completes the crimping, the circular slide plate 514 rises under the action of the spring, and then the fixed end mechanism 5 is reset through the hinge rod 516.

[0043] See also Figure 2 , Figure 3 , Figure 5 and Figure 6The wire carrying part 61 includes a wire carrying platform 611, a first slide 612, a second slide 613 and a second slider 614. The upper end surface of the operating panel 3 is fixedly installed with a wire carrying platform 611 located directly behind the corresponding lower pressing die 424. The upper end surface of the wire carrying platform 611 is penetrated by a left-right symmetrical first slide 612. A placement platform located between the left-right symmetrical first slides 612 and used for placing cables is arranged at the center of the upper end surface of the wire carrying platform 611. The first slide 612 is composed of an inclined slide close to the placement platform and a smooth slide away from the placement platform. The lower end surface of the wire carrying platform 611 is provided with a second slide 613, and a left-right symmetrical second slider 614 is slidably installed in the second slide 613.

[0044] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 The auxiliary part 62 includes a bidirectional screw 621, a gear 622, a tripod 623 and a rack 624. The bidirectional screw 621 threadedly connected to the corresponding left-right symmetrical second sliding block 614 is installed in the second slideway 613 through a bearing. The left end of the bidirectional screw 621 is fixedly sleeved with a gear 622. The rear end surface of the moving seat 422 is fixedly installed with a tripod 623. The end of the tripod 623 away from the corresponding moving seat 422 is fixedly installed with a rack 624 meshing with the gear 622.

[0045] See also Figure 2 , Figure 5 and Figure 6 The clamping part 63 includes a second limiting slide rail 631, a third slider 632, a matching rod 633 and a clamping block 634. The second limiting slide rail 631 is fixedly installed on the front end surface of the second slider 614, and the third slider 632 is slidably installed in the second limiting slide rail 631. A matching rod 633 fixedly connected to the corresponding third slider 632 is slidably installed in the first slide 612. A clamping block 634 is fixedly installed on the upper end of the matching rod 633, and a layer of rubber is wrapped on the outside of the clamping block 634.

[0046] During specific operation, as the moving seat 422 descends, the rack 624 will be brought down through the tripod 623, and when the rack 624 contacts the gear 622, the bidirectional screw 621 will be rotated through the gear 622, thereby bringing the left and right symmetrical second sliders 614 closer together, thereby driving the second limiting slide rails 631 on both sides to approach together. During this process, the matching rod 633 will follow the guide movement of the first slide 612. When the matching rod 633 reaches the inclined slide position of the first slide 612, the matching rod 633 will clamp and fix the cable with the clamping blocks 634 on both sides, thereby ensuring that the cable will not shift during the crimping process and improving the quality of the crimping. Then the bidirectional screw 621 continues to rotate, and the clamping blocks 634 on both sides will push the cable into the terminal block to ensure that the contact area between the cable and the terminal block is maximized, thereby reducing the contact resistance and improving the conductive efficiency.

[0047] The placement plate 512 and the wire loading platform 611 are on the same horizontal plane, so that the terminal fixing mechanism 5 and the wire fixing mechanism 6 respectively fix the terminal and the cable on the same horizontal plane at the same time, thereby ensuring uniform distribution of force during crimping, ensuring closer contact between the cable and the terminal, and improving the electrical performance and mechanical strength after connection.

[0048] When the moving seat 422 rises after the crimping mechanism 4 completes the crimping, the moving seat 422 will reversely rotate the bidirectional screw 621 through the gear 622 to reset the line-fixing mechanism 6.

[0049] See also Figure 1 — Figure 7 Working principle: When the high and low voltage distribution cabinet terminals need to be crimped, the terminals are sleeved on the outside of the matching tube 511, so that the terminals are placed flat on the placement plate 512, and then the placement of multiple subsequent terminals can be repeated.

[0050] When it is necessary to crimp the terminal, start the hydraulic pump fixed on the base 1, and drive the movable seat 422 to descend through the crimping mechanism 4, so that the upper die 423 approaches the lower die 424. During this process, the actuator 42 cooperates with the fixed end mechanism 5 to straighten the position of the terminal and limit the position of the screw hole of the terminal to ensure that the terminal remains fixed during the crimping process of the crimping mechanism 4. At the same time, the cable is clamped and fixed with the cooperation of the crimping mechanism 4 and the fixing mechanism 6, and the cable is pushed into the terminal.

[0051] After the upper die 423 and the lower die 424 cooperate to complete the crimping operation on the terminal, the hydraulic cylinder 411 can be started in reverse to return the connecting cross plate 412 to its original position. When the movable seat 422 rises, the circular slide plate 514 will rise under the action of the spring to reset the fixed end mechanism 5. At the same time, the line fixing mechanism 6 is reset through the bidirectional screw 621. Then the crimped terminal is taken out, and the subsequent processing of the terminal can continue.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
