Description

Technical Field

[0001] The present invention relates to the technical field of connection terminals, in particular to an aluminum alloy high-voltage cable aluminum-copper composite connection terminal. Background Art

[0002] The main function of the terminal block is to connect the wiring harness of the power supply, equipment and external interface for transmitting electrical energy and signals. In the internal wiring of electrical appliances, household appliances, electronic equipment and other products, the terminal block plays an important role in convenient and fast connection, reducing product volume, reducing production costs and improving production efficiency.

[0003] In the prior art, when installing terminal blocks on high-voltage cables, the terminal blocks are first sleeved on the battery cells, and then hydraulic equipment or other tools are used to squeeze the outer wall of the terminal blocks so that the terminal blocks are crimped to the battery cells of the high-voltage cable. However, the battery cell structures inside the high-voltage cable are different. When the battery cells inside the high-voltage cable are composed of multiple thin copper wires, crimping the terminal blocks to the battery cells with multiple thin copper wires can easily cause the thin copper wire battery cells near the inner wall of the terminal blocks to be damaged and broken, affecting the conductivity. When the terminal blocks are rusted after long-term use, the terminal blocks need to be replaced. Since the terminal blocks and the cable are difficult to separate after crimping, the terminal blocks or the battery cells can only be cut, resulting in damage to the battery cells and high costs.

[0032] An aluminum alloy high voltage cable aluminum copper composite terminal, such as Figures 1-4As shown, it includes a terminal block 1, a terminal block 201 is connected to the bottom of the terminal block 1 (the connection method between the terminal block 1 and the terminal block 201 is welding and bolt connection or other methods, which are all existing technologies and are not described here), and also includes a wire harness mechanism, a wire harness mechanism is provided in the terminal block 201, and the wire harness mechanism includes a fastening shaft 202, and four evenly distributed fastening shafts 202 are rotatably connected in the terminal block 201.

[0033] like Figure 1-Figure 3 As shown, the wiring mechanism also includes a swing rod 301, a swing rod 301 is hinged on the wiring frame 201, a through slot is penetrated on the outer wall of the swing rod 301, a connecting frame 302 is provided in the wiring frame 201, one end of the connecting frame 302 is fixedly connected to a sliding shaft used in conjunction with the through slot, a first mounting box 303 is fixedly connected to one side of the swing rod 301, a first elastic wedge block 304 is slidably connected in the first mounting box 303, the first elastic wedge block 304 is slidably connected to the swing rod 301 and is used in conjunction with the sliding shaft of the connecting frame 302, a sliding shaft is fixedly connected to one side of the first elastic wedge block 304, one end of the sliding shaft slides through the first mounting box 303 and is fixed with a disc.

[0034] like Figure 3-Figure 6 As shown, the wiring mechanism also includes a lifting rod 401, the lifting rod 401 is vertically slidably connected to the wiring frame 201, the other end of the connecting frame 302 is hinged to the top of the lifting rod 401, the first contact block 204 is fixed to the lifting rod 401, and the bottom end of the lifting rod 401 is fixed to the connecting frame 402. The top ends of the four fastening shafts 202 are movably connected to the connecting frame 402 in a through-type manner. Two first spiral grooves 403 are provided on the top of the outer walls of the four fastening shafts 202. Four groups of sliders 404 used in conjunction with the first spiral grooves 403 are fixed in the connecting frame 402, each group of two. When the connecting frame 402 is lifted upward, the four fastening shafts 202 can be driven to rotate through the four groups of sliders 404.

[0035] like Figure 3-Figure 5As shown, the wiring harness mechanism also includes a second mounting box 501, and four evenly distributed second mounting boxes 501 are slidably connected in the wiring frame 201. The four second mounting boxes 501 are arranged in a one-to-one correspondence with the four fastening shafts 202. The four second mounting boxes 501 are horizontally slidably connected with a sliding plate 502. A first elastic member is arranged between the sliding plate 502 and the second mounting box 501. The first elastic member is a compression spring. A plurality of evenly distributed ratchets 503 are fixedly connected to one side of the sliding plate 502 close to the fastening shaft 202. Four evenly distributed limit blocks 504 are fixedly connected to the outer wall of the connecting frame 402. The four limit blocks 504 are arranged in a one-to-one correspondence with the four second mounting boxes 501, and the limit blocks 504 are used in conjunction with the plurality of ratchets 503.

[0036] like Figure 1 and 6 - Figure 7 As shown, the wiring harness force detection mechanism also includes an adjusting wheel 601, which is rotatably connected to the wiring frame 201 (the adjusting wheel 601 is engraved with scales, which is existing technology and will not be described here), and the internal thread of the adjusting wheel 601 is connected to a screw 602, and the left end of the screw 602 is fixedly connected to an elastic telescopic rod 603, and the telescopic end of the elastic telescopic rod 603 is fixedly connected to the second contact block 205, and the inner wall of the elastic telescopic rod 603 is fixedly connected to one end of a first elastic clip 604, and is fixedly connected to a blocking block 605 used in conjunction with the first elastic clip 604, and the telescopic end of the elastic telescopic rod 603 can squeeze the first elastic clip 604.

[0037] When installing the terminal block 1, first put the terminal frame 201 on the battery core of the high-voltage cable. At this time, the staff will judge whether it is necessary to adjust the wire harness force detection mechanism according to the condition of the battery core. When the battery core is composed of multiple thinner copper wires, the wire harness force detection mechanism needs to be adjusted to prevent the copper wire from being squeezed and damaged or broken by the wire harness claw 203. First, the staff will turn the adjusting wheel 601 clockwise. When the adjusting wheel 601 rotates, the elastic telescopic rod 603 is driven to move to the left through the screw 602. The telescopic end of the elastic telescopic rod 603 drives the second contact block 205 to slide horizontally to the side close to the first contact block 204. The staff can accurately adjust the position of the second contact block 205 by observing the scale on the adjusting wheel 601. After the adjustment is completed The staff then pulls the bottom end of the swing rod 301 to make the swing rod 301 rotate upward with the connection point of the wiring frame 201 as the center of the circle, and the sliding shaft on the connecting frame 302 slides along the through slot of the swing rod 301, and drives the connecting frame 302 to rotate upward with the connection point of the lifting rod 401 as the center of the circle until the sliding shaft contacts the first elastic wedge block 304. At this time, the sliding shaft squeezes the first elastic wedge block 304, causing the first elastic wedge block 304 to shrink and slide. The sliding shaft continues to slide and passes over the first elastic wedge block 304. After the first elastic wedge block 304 is freed from the restriction, it releases and slides back. Then the swing rod 301 is rotated downward. At this time, the sliding shaft slides downward along the through slot and drives the connecting frame 302 to rotate downward with the connection point of the lifting rod 401 as the center of the circle. The first elastic wedge block 304 limits the sliding shaft so that the sliding shaft cannot slide further. At this time, the first elastic wedge block 304 applies an extrusion force to the sliding shaft, so that the sliding shaft drives the lifting rod 401 to lift and slide upward through the connecting frame 302. The lifting rod 401 drives the connecting frame 402 to lift upward, and the connecting frame 402 drives the four groups of sliders 404 therein to lift upward. Each group of sliders 404 squeezes the first spiral groove 403 of the adjacent fastening shaft 202 respectively, thereby causing the four fastening shafts 202 to drive the cable claws 203 thereon to rotate respectively. The closed space formed by the four cable claws 203 in the same plane begins to shrink, and then the cable claws 203 contact the battery core of the high-voltage cable and The first contact block 204 is squeezed, and at the same time, the lifting rod 401 drives the first contact block 204 to lift and slide upward. After the first contact block 204 slides, its inclined surface contacts and squeezes the inclined surface of the second contact block 205. The second contact block 205 is forced to drive the elastic telescopic rod 603 to shrink and slide. After the telescopic end of the elastic telescopic rod 603 slides, it contacts and squeezes the first elastic clip 604. The first elastic clip 604 begins to deform under the force. The end of the first elastic clip 604 close to the blocking block 605 squeezes the blocking block 605. When the first elastic clip 604 is deformed to a certain extent, the end of the first elastic clip 604 close to the blocking block 605 quickly bounces away from the blocking block 605 and makes a crisp sound. The staff can tell whether the first elastic clip 604 makes a sound.It is determined whether the binding force of the binding claw 203 has reached the appropriate force.

[0038] When the connecting frame 402 is lifted upward, the four limit blocks 504 are lifted up synchronously, and the limit blocks 504 squeeze the adjacent ratchet teeth 503. The ratchet teeth 503 are forced to drive the sliding plate 502 to slide in the second installation box 501, and the first elastic member is forced to contract until the connecting frame 402 and the four limit blocks 504 are no longer lifted upward. The first elastic member is released, so that the ratchet teeth 503 limit the adjacent limit blocks 504, and the limit blocks 504 drive the connecting frame 402 to maintain a stable height, thereby allowing the cable claw 203 to maintain the squeezing force on the battery cell. Then the staff pulls the disc, and the disc drives the first elastic wedge block 304 to contract and slide through the sliding shaft. After the first elastic wedge block 304 slides, it no longer contacts the sliding shaft, and then the disc is released. The first elastic wedge block 304 is released to slide and reset, and then the sliding shaft continues to slide until the connecting frame 302 is reset, thereby completing the fixation of the cable claw 203 to the battery cell.

[0039] When the battery cell is composed of a single copper wire or multiple thicker copper wires, the copper wire is not easily damaged or broken when squeezed by the wire clamping claw 203. There is no need to adjust the wire clamping force detection mechanism. Repeat the above steps to complete the fixing of the battery cell by the wire clamping claw 203. Example

[0040] like Figures 8-10 As shown, the exhaust mechanism also includes a first rotating ring 701, and the lower part of the outer wall of the wiring frame 201 is rotatably connected to the first rotating ring 701. The inner wall of the first rotating ring 701 is provided with two second spiral grooves 702. A pressure ring 703 is provided in the wiring frame 201, and the outer wall of the pressure ring 703 is symmetrically fixed with a guide block 704. The guide block 704 is stuck in the second spiral groove 702 and slides in the second spiral groove 702. When the first rotating ring 701 rotates, the pressure ring 703 can be dropped. The guide block 704 is vertically slidably connected to the wiring frame 201, and an air bag 705 for use with the pressure ring 703 is installed in the wiring frame 201.

[0041] like Figures 8-10 As shown, the exhaust mechanism also includes a second elastic wedge block 801, and vertical grooves are symmetrically opened on the top of the first rotating ring 701. The second elastic wedge block 801 is slidably connected in the vertical groove. The outer wall of the wiring frame 201 is slidably connected to a limit ring 802. The limit ring 802 is located on the upper side of the first rotating ring 701. A second elastic member is arranged between the limit ring 802 and the wiring frame 201. The second elastic member is a compression spring. The bottom of the limit ring 802 is opened with a plurality of limit grooves 803 used in conjunction with the second elastic wedge block 801.

[0042] like Figure 11As shown, the exhaust mechanism further includes an air pump 901 . The air pump 901 is fixedly connected to the inner wall of the exhaust pipe 206 , and a handle 902 is fixedly connected to the telescopic end of the air pump 901 .

[0043] like Figure 11 As shown, a second elastic clip 903 is also included. A convex shaft is fixedly connected to one side of the handle 902, and a second elastic clip 903 is symmetrically fixedly connected to one side of the wiring frame 201. The second elastic clip 903 is used in conjunction with the convex shaft. The second elastic clip 903 can limit the position of the handle 902 through the convex shaft.

[0044] like Figure 12 As shown, a second rotating ring 1001 is also included. The outer wall of the wiring frame 201 is rotatably connected to the second rotating ring 1001. The second rotating ring 1001 is located above the limiting ring 802. The inner wall of the second rotating ring 1001 is fixedly connected to the four second installation boxes 501.

[0045] Initially, the airbag 705 is in a released state. After the cable claw 203 fixes the battery cell, the staff rotates the first rotating ring 701 clockwise. The two second spiral grooves 702 in the first rotating ring 701 squeeze the guide blocks 704 therein, so that the two guide blocks 704 drive the pressure ring 703 to move downward. The pressure ring 703 squeezes the airbag 705. After being squeezed, the airbag 705 deforms and fits the battery cell, filling the gap between the lower part of the inner wall of the wiring frame 201 and the battery cell, so that the gap between the inner wall of the wiring frame 201 and the battery cell forms a tight seal. The sealing space is formed. When the first rotating ring 701 rotates, the two second elastic wedge blocks 801 are driven to rotate synchronously. The inclined surfaces of the second elastic wedge blocks 801 contact the corresponding limiting grooves 803. The second elastic wedge blocks 801 are forced to shrink and slide until the first rotating ring 701 stops rotating. The second elastic wedge blocks 801 are stuck in the corresponding limiting grooves 803, thereby making the pressure ring 703 keep squeezing the airbag 705 to prevent the airbag 705 from resetting. Then the staff pulls out the handle 902, and the handle 902 drives the upper portion thereof. The convex shaft squeezes the second elastic clip 903, and the second elastic clip 903 is deformed by the force, and then the convex shaft passes over the second elastic clip 903, and the second elastic clip 903 is released and reset. At the same time, the handle 902 drives the piston end of the air pump 901 to extend, and the air pump 901 extracts the air in the sealed space formed by the inner wall of the wiring rack 201 and the battery cell, and then pushes the handle 902, and the handle 902 drives the piston end of the air pump 901 to contract, and repeats the above steps until the air in the sealed space formed by the inner wall of the wiring rack 201 and the battery cell is completely Fully extracting the terminal 201 creates a vacuum state inside the terminal frame 201, thereby reducing the increase in resistance due to poor contact and significantly improving the insulation performance of the terminal 1. In the vacuum state, the gas molecules are evacuated and cannot form a discharge channel, thereby avoiding energy loss and equipment damage caused by discharge. Through the cooperation of the wiring mechanism and the exhaust mechanism, the guidance of the terminal 1 can be further improved. The staff then pushes the handle 902 to reset the piston end of the vacuum pump 901, thereby completing the installation of the terminal 1.

[0046] When the terminal block 1 needs to be replaced, the staff first pushes the limit ring 802 upwards, and the second elastic member contracts under the force, so that the limit groove 803 no longer contacts the adjacent second elastic wedge block 801. Then the first rotating ring 701 is rotated to make the pressure ring 703 slide back to its original position. The pressure ring 703 no longer squeezes the air bag 705, and the air bag 705 contracts and no longer contacts the battery cell, so that air enters the inside of the terminal block 201. Then the limit ring 802 is loosened, and the second elastic member is released to drive the limit ring 802 to slide back to its original position, and then the first rotating ring 701 is rotated again. Move the second rotating ring 1001, and the second rotating ring 1001 drives the four second installation boxes 501 to rotate. The second installation boxes 501 drive the plurality of ratchets 503 to rotate through the sliding plate 502, so that the plurality of ratchets 503 are away from the corresponding limit blocks 504. After the limit blocks 504 are released from the restriction, the connecting frame 402 can move, and the connecting frame 402 falls under its own weight, thereby causing the four fastening shafts 202 to drive the corresponding wire claws 203 to rotate and reset. The wire claws 203 are no longer in contact with the battery cell, and then the wiring frame 201 can be removed.

[0047] Then, the new terminal block 1 is connected to the terminal frame 201 , and the above steps are repeated to connect the new terminal block to the high-voltage cable, thereby effectively reducing the cost.
