Description

Technical Field

[0001] The invention relates to the technical field of wiring terminals, and in particular to an aluminum alloy high-voltage cable aluminum-copper composite wiring 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 wiring terminals on high-voltage cables, the wiring terminals are first sleeved on the battery cells, and then hydraulic equipment or other tools are used to extrude the outer wall of the wiring terminals so that the wiring terminals are crimped with the battery cells of the high-voltage cable. However, the battery cell structure inside the high-voltage cable is not the same. When the battery cells inside the high-voltage cable are composed of multiple thin copper wires, crimping the wiring terminals with the battery cells of the multiple thin copper wires can easily cause the thin copper wire battery cells close to the inner wall of the wiring terminals to be damaged and broken, affecting conductivity. When the wiring terminals are rusted after long-term use, the wiring terminals need to be replaced. Since the wiring terminals and the cable are difficult to separate after crimping, the wiring terminals or the battery cells can only be cut, resulting in damage to the battery cells, which is costly.

[0021] like Figure 1-Figure 3 As shown, the wiring harness mechanism also includes a swing rod 301, the swing rod 301 is hinged on the wiring frame 201, the outer wall of the swing rod 301 is penetrated with a through slot, a connecting frame 302 is arranged in the wiring frame 201, one end of the connecting frame 302 is fixedly connected with a sliding shaft used in conjunction with the through slot, a first installation 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 installation box 303, the first elastic wedge block 304 is slidably connected to the swing rod 301 in a through manner, 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 installation box 303 and is fixedly connected with a disc.

[0022] like Figure 3-Figure 6 As shown, the wiring harness mechanism also includes a lifting rod 401, the lifting rod 401 is vertically slidably connected in 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 fixedly connected to the lifting rod 401, and the bottom end of the lifting rod 401 is fixedly connected 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, and the tops of the outer walls of the four fastening shafts 202 are each provided with two first spiral grooves 403, and four groups of sliders 404 used in conjunction with the first spiral grooves 403 are fixedly connected in the connecting frame 402, each group of two, and 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.

[0023] like Figure 3-Figure 5As shown, the wiring harness mechanism also includes a second installation box 501, and four evenly distributed second installation boxes 501 are slidably connected in the wiring frame 201, and the four second installation boxes 501 are arranged in a one-to-one correspondence with the four fastening shafts 202. The four second installation boxes 501 are horizontally slidably connected with a sliding plate 502, and a first elastic member is arranged between the sliding plate 502 and the second installation box 501. The first elastic member is a compression spring, and a side of the sliding plate 502 close to the fastening shaft 202 is fixedly connected with a plurality of evenly distributed ratchets 503, and the outer wall of the connecting frame 402 is fixedly connected with four evenly distributed limit blocks 504, and the four limit blocks 504 are arranged in a one-to-one correspondence with the four second installation boxes 501, and the limit blocks 504 are used in conjunction with the plurality of ratchets 503.

[0024] 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 the prior art and will not be described here), and the adjusting wheel 601 is internally threadedly connected to a lead screw 602, and the left end of the lead 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.

[0025] When installing the terminal block 1, first put the terminal frame 201 on the battery cell of the high-voltage cable. At this time, the staff will determine whether it is necessary to adjust the wire harness strength detection mechanism according to the situation of the battery cell. When the battery cell is composed of multiple thinner copper wires, it is necessary to adjust the wire harness strength detection mechanism 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 lead 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 observes the scale on the adjusting wheel 601 to accurately adjust the position of the second contact block 205. After the adjustment is completed , and then the staff 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, 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, 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, and 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 to reset, and 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. The first elastic wedge block 304 limits the sliding shaft so that the sliding shaft cannot continue to slide. 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, so that the four fastening shafts 202 respectively drive the cable catching claws 203 thereon to rotate, and the closed space formed by the four cable catching claws 203 on the same plane begins to shrink, and then the cable catching claws 203 contact the battery core of the high-voltage cable and 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 see whether the first elastic clip 604 makes a sound.It is determined whether the cable tie force of the cable tie claw 203 reaches the appropriate force.

[0026] When the connecting frame 402 is lifted upward, the four limit blocks 504 are driven to rise synchronously. 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 shrink 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 adjacent limit blocks 504 are limited by the ratchet teeth 503. The limit blocks 504 drive the connecting frame 402 to maintain a stable height, thereby allowing the wire harness 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 shrink and slide through the sliding shaft. After sliding, the first elastic wedge block 304 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 wire harness claw 203 to the battery cell.

[0027] 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. Repeating the above steps can complete the fixing of the battery cell by the wire clamping claw 203. Example

[0028] like Figure 8-Figure 10 As shown, the exhaust mechanism also includes a first rotating ring 701, and the first rotating ring 701 is rotatably connected to the lower part of the outer wall of the wiring frame 201. The inner wall of the first rotating ring 701 is provided with two second spiral grooves 702. A pressure ring 703 is arranged in the wiring frame 201, and a guide block 704 is symmetrically fixed to the outer wall of the pressure ring 703. 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 used in conjunction with the pressure ring 703 is installed in the wiring frame 201.

[0029] like Figure 8-Figure 10 As shown, the exhaust mechanism also includes a second elastic wedge block 801, and vertical grooves are symmetrically provided 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, and 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, and the second elastic member is a compression spring. The bottom of the limit ring 802 is provided with a plurality of limit grooves 803 used in conjunction with the second elastic wedge block 801.

[0030] like Fig.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 .

[0031] like Fig.11 As shown, a second elastic clip 903 is also included. A convex shaft is fixedly connected to one side of the handle 902. 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.

[0032] like Fig.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.

[0033] 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, and 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, and the pressure ring 703 squeezes the airbag 705. After being squeezed, the airbag 705 deforms and fits the battery cell, and fills 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 first rotating ring 701 rotates, driving the two second elastic wedge blocks 801 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 shrink and slide under the force until the first rotating ring 701 stops rotating. The second elastic wedge blocks 801 are stuck in the corresponding limiting grooves 803, so that the pressure ring 703 keeps 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 pressure ring 703 to squeeze the airbag 705. 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, and 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 repeat 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 pull out to form a vacuum state inside the terminal frame 201, thereby reducing the increase in resistance caused by 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 bundle mechanism and the exhaust mechanism, the guidance of the terminal 1 can be further improved. Then the staff pushes the handle 902 to reset the piston end of the vacuum pump 901, thereby completing the installation of the terminal 1.

[0034] 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, and then rotates the first rotating ring 701 to make the pressure ring 703 slide back to its original position, and 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 wiring rack 201, and then loosens the limit ring 802, and the second elastic member is released to drive the limit ring 802 to slide back to its original position, and then rotates again. The second rotating ring 1001 is moved, 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, so that the four fastening shafts 202 drive the corresponding wire claws 203 to rotate and reset, and the wire claws 203 are no longer in contact with the battery cell, and then the wiring frame 201 can be removed.

[0035] Then the new terminal block 1 is connected to the terminal frame 201, and the above steps are repeated to connect with the high-voltage cable, which effectively reduces the cost.

[0036] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
