Technical Field

[0001] This utility model relates to the field of cable terminal production technology, specifically to a power terminal crimping and forming device. Background Technology

[0002] The power terminal crimping and forming device is a special equipment used to achieve reliable electrical connection and mechanical fixation between power terminals and wires. Its core function is to apply mechanical pressure to cause the terminals and wires to undergo plastic deformation under the action of the mold, thereby forming a stable connection structure.

[0003] However, the crimping and forming devices used for electrical wire terminals in current power applications are generally operated by manual feeding and hydraulic rods. However, due to the different thicknesses of different cables, the crimping terminals used are also different. The current crimping and forming devices can generally only crimp a single specification of electrical terminal, which is quite limited in use and cannot be quickly adjusted according to the needs of use. Utility Model Content

[0004] The purpose of this invention is to provide a power terminal crimping and forming device to solve the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, the power terminal crimping and forming device includes a base plate 1, and also includes:

[0023] A support plate 2 is fixed to the top rear side of the base plate 1. A groove 3 is provided inside the support plate 2. A connecting plate 4 is provided on the front side of the support plate 2. A hydraulic rod 5 is fixedly connected to the bottom of the connecting plate 4. A slider 6 that slides and connects with the inside of the groove 3 is fixedly connected to one side of the connecting plate 4.

[0024] The limiting groove 7 is set inside the support plate 2. The limiting groove 7 is arranged with a pressing component 8. The piston end of the hydraulic rod 5 is fixedly connected to the insertion block 9. The base plate 1 and the support plate 2 can facilitate the support of the connecting plate 4 and the hydraulic rod 5. The setting of the sliding groove 3 and the slider 6 can adjust the position of the connecting plate 4 and the hydraulic rod 5. The limiting groove 7 is set with three, which work with the pressing component 8 to passively cooperate with the insertion block 9 on the hydraulic rod 5, so as to achieve the function of crimping cables of different thicknesses.

[0025] The crimping component 8 includes a first spring 801, a movable plate 802, an insert shell 803, a connecting post 804, crimping blocks 805, and a crimping shell 806. The first spring 801 is fixed to the bottom of the inner cavity of the limiting groove 7, and its top is fixedly connected to the movable plate 802. The insert shell 803 is fixed to one side of the movable plate 802. The connecting post 804 is fixed to the bottom of the insert shell 803, and its bottom is fixedly connected to the crimping block 805. The crimping shells 806 are arrayed and fixedly fixed to the top of the base plate 1. A sliding rod 807 is fixedly connected to the bottom of the movable plate 802. The surface of the sliding rod 807 is slidably connected to the inside of the support plate 2. A T-shaped groove 808 is provided inside the insert shell 803. The surface of the T-shaped groove 808 is movably engaged with the surface of the insert block 9. Firstly, the three crimping blocks 805 and the crimping shell 806 decrease in size from left to right. Therefore, when the insert block 9 is inserted... When the cable and crimp connector are inside the housing 803, the hydraulic rod 5 is driven to insert the plug 9 into the T-shaped groove 808 inside the housing 803 and lower it. At this time, the movable plate 802 and the first spring 801 will be driven to descend and compress inside the housing 803. When the movable plate 802 descends, it will drive the slide rod 807 to descend and limit it inside the support plate 2, thereby improving the stability of the movable plate 802 when it moves. As the housing 803 moves, it will drive the connecting column 804 to lower the crimping block 805 into the housing 806, thereby crimping and forming the cable and terminal. However, the unused movable plate 802 will be held at the top of the cavity of the limiting groove 7 by the elasticity of the first spring 801, so that the plug 9 can be stably inserted into the housing 803 when the hydraulic rod 5 drives the plug 9 to move horizontally.

[0026] An extension frame 10 is fixedly connected to the top of the slider 6. A second spring 11 is fixedly connected to one side of the extension frame 10. A locking block 12 is fixedly connected to the bottom of the second spring 11. A pull rod 13, which slides inside the extension frame 10, is fixedly connected to the top of the locking block 12. The top of the support plate 2 has slots 14 that mate with the locking block 12. The slots 14 are located at the top of the limiting groove 7. A push handle 15 is fixedly connected to the top of the connecting plate 4. A reinforcing block 16 is fixedly connected between one side of the support plate 2 and the base plate 1. Through the extension frame 10, the second spring 11, and the locking block 12, the connecting plate 4 can be adjusted by the user. When the hydraulic rod 5 is positioned to engage with the insert block 9 to insert into other insert housings 803, first pull the pull rod 13. At this time, the pull rod 13 will drive the locking block 12 to disengage from the slot 14 and compress the second spring 11. Then push the slider 6 to move inside the slide groove 3 until the locking block 12 is aligned with the next slot 14 with the center of the slot. At this time, the insert block 9 will also be inserted into another insert housing 803, which facilitates the crimping of thicker cables. The push handle 15 makes it easy for the operator to push the connecting plate 4 and the slider 6 to move. The reinforcing block 16 can strengthen the connection between the support plate 2 and the base plate 1.

[0027] Working principle: When the user needs to adjust the position of the hydraulic rod 5 to cooperate with different inserts 803 and crimping blocks 805 to crimp cables and terminals of different thicknesses, the user first pulls the pull rod 13. At this time, the pull rod 13 will drive the locking block 12 to disengage from the slot 14 and compress the second spring 11. Then, it will push the slider 6 to move inside the slide groove 3 until the locking block 12 is aligned with the next slot 14 with the center of the slot. At this time, the insert block 9 will also be inserted into the other insert 803. Then, the cable and crimping connector are placed on the crimping block. Inside the housing 806, the hydraulic rod 5 is driven to insert the plug 9 into the T-shaped groove 808 inside the housing 803 and lower it. At this time, the movable plate 802 and the first spring 801 will be driven to descend and compress inside the housing 803. When the movable plate 802 descends, it will drive the slide rod 807 to descend within the support plate 2, thereby improving the stability of the movable plate 802 when it moves. As the housing 803 moves, it will drive the connecting column 804 to lower the crimping block 805 into the housing 806, thereby crimping and forming the cable and terminal.
