[0002] With the acceleration of urbanization and the development of information technology, people's demand for electricity is increasing, and at the same time, higher requirements are placed on the stability and safety of the power supply system. In this context, how to efficiently and safely complete power cable-related operations has become an important issue. Traditional manual operation methods are not only inefficient but also have great safety hazards. Therefore, it is particularly important to develop professional tools that can simplify processes, improve work efficiency and ensure personnel safety.

[0003] After searching, the patent authorization announcement number is CN118523224B, which discloses a new type of cable branching device for power cable construction, including a shell, a cover plate is fixedly provided on the upper side of the shell by bolts, a mounting plate is fixedly provided on the lower side of the shell by welding, a first through hole is provided at the front end of the shell, a plurality of second through holes are provided at intervals at the rear end of the shell, and a clamping assembly is provided in the middle of the interior of the shell; the above-mentioned branching device is provided with a trapezoidal block in the threading hole, and when the cable is pulled, the trapezoidal block can clamp the cable to prevent the cable from being pulled out of the shell; however, there are still certain limitations in use.

[0029] Embodiment 1: A power cable construction splitter device that facilitates line splitting, such as Figure 2-Figure 5As shown, it includes an installation frame 1, which is a branching carrier of the device. The installation frame 1 is a frame with an open top. The upper part of the front and rear side walls of the installation frame 1 is provided with multiple groups of symmetrical installation grooves 101. The lower part of the front and rear side walls of the installation frame 1 is symmetrically provided with multiple groups of wiring holes 2 with the same number as the installation grooves 101. Each group of wiring holes 2 is provided with two mutually adapted wiring holes. The wiring holes 2 are used for placing the cables 100 into the installation frame 1 for branching and wiring. The wiring holes 2 of the installation frame 1 are all provided with cocks 3; it also includes: a wiring mechanism 4, which is provided with multiple groups and is all arranged inside the installation frame 1. The wiring mechanism 4 includes: two fixing plates 401, which are symmetrically fixed to the inner bottom of the installation frame 1, and a circular through hole is opened on the fixing plate 401. The fixing plate 401 is inclined with the circular through hole as the center.

After the cable 100 is limited by the limiting mechanism 7, the rotating block 406 is rotated by turning and pressing the operating rod 5 at the corresponding position. The two rotating rotating blocks 406 drive the lower clamping block 404 and the upper clamping block 405 to move through the driving rod 407 thereon. The lower clamping block 404 and the upper clamping block 405 will rotate toward each other along the guide groove 402 on the fixed plate 401 and approach each other until the lower clamping block 404 and the upper clamping block 405 clamp and conduct the wiring terminals of the two cables 100 through the conducting parts inside them, and lock the operating rod 5 through the locking piece 6 to keep the cable 100 stable after wiring, so that the cable 100 can be easily disconnected and separated by using the operating rod 5.

[0030] like Figure 4 and Figure 5 As shown, the conducting member includes a conducting plate 501 and conductive teeth 502, the lower clamp block 404 and the upper clamp block 405 are made of insulating material, the clamping surfaces of the lower clamp block 404 and the upper clamp block 405 are both wavy arc clamps, the conducting plate 501 is an arc plate installed and covered on the clamping surfaces of the lower clamp block 404 and the upper clamp block 405 respectively, the conducting plate 501 is a conductive material, a plurality of conductive teeth 502 are evenly arranged on the contact surface of the conducting plate 501, the conductive teeth 502 are distributed on the contact surface of the conducting plate 501 in an "eight" shape, and the ends of the conductive teeth 502 are pointed. When the conducting plate 501 is driven by the lower clamp block 404 and the upper clamp block 405 to clamp the cable 100 up and down, the conductive teeth 502 on the conducting plate 501 will bite and embed into the surface of the wiring metal end of the cable 100, thereby improving the stability of the two cables 100 when wiring.

[0031] like Figure 2 and Figure 5 As shown, the locking member 6 includes a mounting block 601 and a hook 602. The mounting block 601 is symmetrically fixedly mounted on the outer walls of both sides of the two fixing plates 401 of the same group. The mounting block 601 is a square block with a hollow interior. The hook 602 is rotatably mounted on the mounting block 601. The top of the hook 602 is an inclined surface and its end is in the shape of a barb. The hook 602 is used to lock the rod bodies of both sides of the operating rod 5 from both sides. After the operating rod 5 is pressed down to allow the wiring mechanism 4 to clamp the cable 100 for wiring, the pressed operating rod 5 is limitedly locked by toggling the hook 602, so that the wiring mechanism 4 can stably connect the cables 100 at two locations.

[0032] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, the limiting mechanism 7 includes: a sliding plate 701, which is slidably installed on the installation frame 1 through the installation groove 101, and a sliding groove is opened inside the sliding plate 701; a sliding rod 702, which is movably installed on the sliding plate 701 through a ring 703, and the ring 703 is located in the sliding groove of the sliding plate 701 and is in active contact; a limiting frame 704, which is fixed to the lower end of the sliding rod 702, and a limiting groove is symmetrically opened in the limiting frame 704; two connecting rods 705, which slide symmetrically through the limiting grooves Installed on the limit frame 704; arc clamp block 706, fixed on the connecting rod 705, the arc clamp block 706 is symmetrically distributed in a semicircular arc shape, and the arc clamp block 706 is used to clamp and limit the cable 100 outside the installation frame 1. The lower part of the arc clamp block 706 is also fixed with a connecting rod 705, and the two connecting rods 705 are also limited in the corresponding limit frame 704; the rubber clamp pad 707 is arranged and covered on the clamping surface of the arc clamp block 706; the spring 708 is arranged on the upper Between the two connecting rods 705 at the lower and lower parts, the spring 708 is used to provide the clamping force of the two arc clamping blocks 706 to limit the cable 100 inwardly. When the cable 100 passes through the two opened arc clamping blocks 706 on the same side and then is placed into the installation frame 1 through the wiring hole 2, the cable 100 is clamped inwardly by the two arc clamping blocks 706 under the action of the spring 708. While limiting the cable 100, the cable 100 can be flexibly adjusted at the wiring angle outside the installation frame 1, thereby improving the applicable scope of the wiring of the device; inclined limiting tooth blocks are evenly distributed on the clamping surface of the rubber clamping pad 707, and the limiting tooth blocks on the rubber clamping pad 707 are inclined toward one side of the installation frame 1. The limiting tooth blocks of the rubber clamping pad 707 provide resistance in the opposite direction to the direction when the cable 100 is placed, so that the cable 100 connected to the installation frame 1 is subjected to the reverse resistance of the rubber clamping pad 707 when being pulled out, thereby improving the stability and safety of the cable 100 connected to the installation frame 1.

[0033] When using the present device to branch and connect the power cable 100, the user first confirms the cable 100 that needs to be branched and connected, and unscrews the plug 3 in the wiring hole 2 that needs to be used. After overcoming the elastic force of the spring 708, the user pushes the connecting rod 705 outward to open the arc clamping block 706 on the connecting rod 705, and then passes the cable 100 through the two arc clamping blocks 706 and the corresponding wiring hole 2 in turn to ensure that the cable 100 can smoothly enter the wiring mechanism 4 inside the installation frame 1. After loosening the connecting rod 705, the limiting mechanism 7 starts to work. Under the guidance of the limiting frame 704, the two connecting rods 705 are acted upon by the elastic force of the spring 708, and drive the two arc clamping blocks 706 to clamp the passed cable 100 inward, thereby The cable 100 outside the installation frame 1 is effectively limited. Since the sliding rod 702 is movably installed on the sliding plate 701, the cable 100 clamped in the arc clamp block 706 is allowed to flexibly adjust the wiring angle outside the installation frame 1. Since the arc clamp block 706 contacts the cable 100 through the rubber clamping pad 707 inside it, while avoiding damage to the surface of the cable 100, the inclined limiting tooth block on the rubber clamping pad 707 can be limited on the surface of the cable 100. When the cable 100 is pulled toward the outside of the installation frame 1, the rubber clamping pad 707 is inclined and tangentially limited to the surface of the cable 100 through the limiting tooth block thereon and provides reverse resistance, so as to avoid the cable 100 from directly affecting its wiring metal end when it is pulled outward, thereby To improve the stability of the cable 100 when it is connected, once the cable 100 is positioned by the limiting mechanism 7, the user holds and presses down the operating rod 5 corresponding to the connection point of the cable 100. As the operating rod 5 rotates, the rotating block 406 connected thereto begins to rotate, thereby driving the driving rod 407 connected thereto to move. Since the driving rod 407 is respectively connected to the lower clamping block 404 and the upper clamping block 405, when the driving rod 407 rotates, the lower clamping block 404 and the upper clamping block 405 are prompted to move toward each other along the guide groove 402 on the fixed plate 401 and continue to approach each other. Finally, the lower clamping block 404 and the upper clamping block 405 will be clamped on the cable 100 terminal respectively. At this time, the conducting plate 501 inside the lower clamping block 404 and the upper clamping block 405 will be clamped and contacted. The surface of the cable 100 terminal makes the multiple conductive teeth 502 on the conductive plate 501 physically bite on the metal end surface of the cable 100, ensuring that the two connected cables 100 maintain a good electrical connection and improving the stability of the cable 100 connector. When the operating rod 5 is pressed down for connection, it will be squeezed on the top inclined surface of the corresponding hook 602, so that the hook 602 rotates on the mounting block 601. When the lower clamping block 404 and the upper clamping block 405 stably clamp the cable 100, the operating rod 5 is pressed down to the maximum stroke. At this time, by toggling the hook 602 in the mounting block 601, the hooks 602 on both sides are simultaneously buckled onto the operating rod 5, thereby locking the operating rod 5, so that the lower clamping block 404 and the upper clamping block 405 can firmly connect the two sections of the cable 100.

[0034] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 8 As shown, a push-pull member 8 is provided between the operating rod 5 and the sliding plate 701, and the push-pull member 8 includes: a connecting block 801, symmetrically fixed to the side wall of a sliding plate 701 of the same group on the installation frame 1; a pull rod 802, hinged between the connecting block 801 and the operating rod 5 of the same group; a gear 803, rotatably installed on the outer wall of the two fixed plates 401 of the same group; a rack 804, fixed to the side wall of another sliding plate 701 of the same group on the installation frame 1; a tooth 805, provided on the arc segment of the edge of the rotating block 406 near the rack 804, a section of the tooth 805 of the rotating block 406 and the rack 804 are meshed with each other, and the wiring mechanism 4 is clamped and When the cable 100 is connected, by rotating and pressing the operating rod 5 to rotate the rotating block 406, the rotating block 406 will synchronously drive the pull rod 802 and the tooth 805, and pull the connecting block 801 through the pull rod 802. At the same time, a section of the tooth 805 of the rotating block 406 engages with the driving gear 803, and then engages the rack 804 through the gear 803, so that the two sliding plates 701 in the same group move toward each other, so that the cable 100 limited in the arc clamp 706 can bend inward for a section after wiring, thereby improving the risk resistance of the cable 100 when it is pulled out, and avoiding the external pulling of the cable 100 directly transmitted and affecting its wiring terminal.

[0035] like Figure 1 , Fig. 9 and Fig.10 As shown, a synchronous member 9 is provided between two adjacent operating rods 5, and the synchronous member 9 includes: a limit block 901, which is fixedly connected to one side of the two adjacent operating rods 5 that are close to each other, and a clamping groove is provided on one side of the limit block 901; a clamping slot block 902, which is fixedly connected to the other side of the two adjacent operating rods 5 that are close to each other, and a clamping slot that is compatible and consistent with the limit block 901 is provided on one side of the clamping slot block 902; a clamping block 903, which is slidably installed in the clamping groove of the limit block 901, and the width of the clamping block 903 is equal to the width of the clamping groove of the limit block 901 The width of the card block 903 is greater than the width of the clamping groove of the card slot block 902. When the card block 903 slides and is simultaneously clamped in the clamping groove between the limit block 901 and the card slot block 902, the limit block 901 and the card slot block 902 will be buckled into one, so that two adjacent operating rods 5 are connected together. By operating one of the operating rods 5, the other operating rods 5 will be driven to move synchronously under the action of the synchronous member 9, which saves the user from having to operate each operating rod 5 separately for separate wiring operations, thereby improving the convenience of synchronous wiring removal or wiring.

[0036] like Figure 1 and Fig.10As shown, an insulating accordion cover 10 is provided at the top opening of the installation frame 1. The insulating accordion cover 10 is retractable. There are multiple insulating accordion covers 10 that are independent of each other. The operating rods 5 respectively pass through the independent insulating accordion covers 10. The multiple insulating accordion covers 10 together cover the top opening of the entire installation frame 1. The insulating accordion cover 10 is used to cover the installation frame 1 and provide protection for the cables 100 connected thereto, thereby improving the safety of the device. The wiring holes 2 of the installation frame 1 are all provided with sealing rings 11, and the plugs 3 are screwed into the sealing rings 11 of the corresponding wiring holes 2 through threads. Different wiring holes 2 of the installation frame 1 are used to provide different wiring schemes for the cables 100. The plugs 3 are used to provide protection for the wiring holes 2 that are screwed into the unused wiring holes 2 to prevent dust or impurities from entering the installation frame 1 and causing adverse effects on the cable 100 lines.

[0037] When the user rotates and presses down the operating rod 5 to drive the wiring mechanism 4 to clamp the cable 100, the push-pull member 8 starts to work, and the rotating operating rod 5 drives the rotating block 406 to rotate. The rotating rotating block 406 will engage the gear 803 through the teeth 805 on its edge, so that the gear 803 rotates and engages the driving rack 804 to move inward. The inwardly moving rack 804 will drive the sliding plate 701 on the same side to move synchronously. At the same time, when the operating rod 5 is pressed down and rotated, the operating rod 5 will also pull the pull rod 802, so that the pull rod 802 acts on the connection block 801 synchronously and pulls the sliding plate 701 on the same side to slide inward, thereby realizing that when the operating rod 5 is pressed down, the limit mechanisms 7 on both sides of the installation frame 1 will move inward synchronously, and at this time, the arc clamping blocks 706 at the two places can bend the clamped cable 100 slightly inward for a distance after wiring, thereby increasing the risk resistance of the cable 100 when it is pulled out, and reducing the impact of external pulling on the cable 100 joint, protecting the cable 100 joint from direct physical stress, thereby improving the safety of the overall connection. The utility model discloses a method for improving the working efficiency of the present invention, and the ...
