Technical Field
[0001] This utility model relates to the field of wire installation technology, specifically a wire clamp that combines wire splitting and grounding functions. Background Technology
[0002] Line clamps for power distribution networks are key metal accessories used to fix, connect, and protect conductors in power systems. Line clamps with branching functions play an important role in distributing electrical energy in power grids. The branching mechanism ensures the stability of the connection, and must prevent the main line from being too tight and damaging the insulation layer, and prevent the branch line from being too loose and falling off. Therefore, a stable and reliable branching mechanism is particularly important.
[0003] However, in existing technologies, the splitting and grounding functions are usually implemented by separate components, which leads to problems such as cumbersome installation steps, complex overall structure, and large space occupation. Furthermore, existing cable clamps typically require special tools to tighten the bolts to secure the cable, which is inconvenient for operation at heights and carries the risk of bolts falling off. Additionally, the groove position for cable placement is relatively fixed, making it difficult to adjust for different cable entry directions, resulting in poor performance. Therefore, a cable clamp that integrates both splitting and grounding functions is proposed. Utility Model Content
[0004] Based on this, the present invention aims to at least solve one of the technical problems existing in the prior art. To this end, a wire clamp that combines wire splitting and grounding functions is proposed, which can simplify the steps of fixing the wire clamp to the cable and improve the efficiency of manual work at heights.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire clamp that combines the functions of wire splitting and grounding, including a base, with positioning clamps fixed on both sides of the top of the base, and a movable clamp provided on the inner side of each set of positioning clamps;
[0006] The base is equipped with a lead screw that rotates along its length. The outer wall of the lead screw is threaded with two sets of connecting plates that can pull the movable clamps to move. The top of the connecting plates is connected to the movable clamps so as to drive the two sets of movable clamps to move synchronously towards or away from each other along the top of the base. The bottom of the base is equipped with a grounding ring.
[0007] As a preferred technical solution, both sides of the movable clamp are provided with arc-shaped grooves for clamping cables; the movable clamp on one side of the base and the corresponding positioning clamp form a first unit groove, and the movable clamp on the other side of the base and the corresponding positioning clamp form a second unit groove.
[0008] As a preferred technical solution, the first unit groove has multiple arc-shaped grooves on its wall, and the second unit groove has protrusions on its wall.
[0009] As a preferred technical solution, the base is composed of two modular seats connected by a damping cylinder.
[0010] As a preferred technical solution, the lead screw is a bidirectional lead screw, and one end of the lead screw extends to the outside of the base and is fixed with a handle.
[0011] As a preferred technical solution, the top of the connecting plate is provided with a connecting part with a threaded hole, and the movable clamp is fixed to the connecting part by bolts.
[0012] As a preferred technical solution, a kit is fixed to the bottom of the connecting plate. The kit has an internal thread that engages with the thread of the bidirectional lead screw. A lead screw groove is provided on the base for the kit to move, and a clearance groove is provided for the connecting plate to move.
[0013] In summary, the present invention has the following main advantages:
[0014] This invention features a movable clamp design that adapts to cables of different sizes, simplifying the installation process and preventing damage to the insulation layer from excessively tight main wires or detachment of branch wires due to excessive looseness. The screw mechanism, operated with a handle, allows for synchronous adjustment of the movable clamp without the need for special tools, reducing the risks associated with working at heights and the potential for bolts to fall off. The integrated design of the grounding ring and module base provides grounding functionality on top of the branching function, saving space and improving overall reliability. The arc-shaped groove of the first unit slot and the raised structure of the second unit slot enhance cable fixing stability, adapt to different cable entry directions, and improve overall performance.

Detailed Implementation
[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0023] The embodiments of this utility model will be described below based on its overall structure.
[0024] A wire clamp that combines the functions of wire splitting and grounding, such as Figures 1 to 6 As shown, it includes a base 100, and positioning clips 120 are fixed on both sides of the top of the base 100. Each set of positioning clips 120 has a movable clip 130 on its inner side.
[0025] A lead screw 190 is rotatably provided inside the base 100 along its length. Two sets of connecting plates 170 are threaded onto the outer wall of the lead screw 190, which can pull the movable clamp 130 to move. The top of the connecting plate 170 is connected to the movable clamp 130, so as to drive the two sets of movable clamps 130 to move synchronously towards or away from each other along the top of the base 100. A grounding ring 110 is assembled at the bottom of the base 100.
[0026] The base 100 is composed of two module seats 101 connected by a damping cylinder 180.
[0027] Both sides of the movable clamp 130 are provided with arc-shaped grooves for clamping cables; the movable clamp 130 on one side of the base 100 and the corresponding positioning clamp 120 form a first unit groove 140, and the movable clamp 130 on the other side of the base 100 and the corresponding positioning clamp 120 form a second unit groove 150. The groove wall of the first unit groove 140 is provided with multiple arc-shaped grooves 141, and the groove wall of the second unit groove 150 is provided with protrusions 151.
[0028] A kit 171 is fixed to the bottom of the connecting plate 170. The kit 171 has an internal thread and is threaded to the lead screw 190.
[0029] The top of the connecting plate 170 is provided with a connecting part with a threaded hole, and the movable clamp 130 is fixed to the connecting part by bolts. This allows the cable to be placed on the upper surface of the base 100, positioned between the movable clamp 130 and the positioning clamp 120. Then, the handle 160 at one end of the lead screw 190 is rotated, causing the lead screw 190 to rotate accordingly. This drives the two sets of threaded connecting plates 170 to move synchronously towards or away from each other within the lead screw groove 103 along the length of the lead screw 190. The movement of the connecting plate 170 pulls the movable clamp 130 fixed to it through the connecting part at its top, causing the two sets of movable clamps 130 to slide linearly along the top of the base 100, moving closer to or away from the positioning clamp 120.
[0030] As the movable clamp 130 approaches the positioning clamp 120, the cable placed between the positioning clamp 120 and the movable clamp 130 is gradually pressed into the first unit slot 140 or the second unit slot 150.
[0031] The inner wall of the positioning clamp 120 is provided with two sets of grooves 121;
[0032] For cables with insulating rubber on the outside, they can be placed in the first unit slot 140. The outer wall of the cable fits against the curved surface of the multiple sets of arc-shaped slots 141 inside the slot, increasing the contact area and friction to prevent the cable from slipping. For bare cables without insulating rubber on the outside, they can be placed in the second unit slot 150. When the cable is pressed, the protrusions 151 on the slot wall will cause local deformation of the cable's metal surface and embed it into the groove 121 on the inner wall of the positioning clamp 120, providing additional mechanical biting and fixing force to ensure stable clamping of the cable. The grounding ring 110 is assembled and connected to the bottom of the module base 101. After the cable is fixed, the base 100 can be grounded as a whole through the grounding ring 110, realizing the integration of the branching mechanism and the grounding function.
[0033] After the clamping operation is completed, the two sets of module seats 101 are flexibly rotated and connected by the damping cylinder 180, which allows the module seats 101 to automatically adjust the angle during the clamping process to adapt to the non-parallel state of the two sets of cables, thereby ensuring that the cables are firmly clamped and fixed, and improving the stability and adaptability of the overall structure.
[0034] The lead screw 190 is a two-way lead screw, and one end of the lead screw 190 extends to the outside of the base 100 and is fixed with a handle 160.
[0035] The base 100 has a lead screw groove 103 for the movement of the kit 171, and a clearance groove 102 for the movement of the connecting plate 170.
[0036] When the lead screw 190 is rotated, the threaded structures in two directions on its outer side will simultaneously drive the two sets of movable clamps 130 to move in opposite directions, thereby effectively clamping the cable and ensuring a firm fixation. The whole process is simple and efficient.
[0037] The top of the connecting plate 170 is fixed with a bolt mounting structure for connecting the movable clamp 130, and the movable clamp 130 is fixed to the bolt mounting structure by bolts.
[0038] The bolts can be tightened using appropriate tools such as wrenches or screwdrivers, thus enabling the installation and removal of the movable clamp 130 to be completed smoothly.
[0039] The parts of the device not covered herein are the same as or can be implemented using existing technologies.
