Description

Technical Field

[0001] This utility model relates to the field of power equipment clamp technology, and more specifically to a forked-finger clamp. Background Technology

[0002] Currently, the various electrical devices on the power transmission equipment are connected to the energized equipment terminals by means of conductors to complete the power transmission. The conductors and equipment terminals are in contact with each other by clamps, and bolts are used to fix the clamps to the equipment terminals.

[0003] Currently, the clamps used are single-sided structures, resulting in a small contact area between the clamps and the equipment terminals. Furthermore, under prolonged load current conditions and exposure to high outdoor temperatures and oxidation, the connection between the clamps and the equipment terminals is prone to overheating, affecting the normal operation of the equipment. In severe cases, this can even burn out the equipment and cause an accident. After such an accident, power outages are required for maintenance and equipment replacement, resulting in countless direct and indirect losses. Utility Model Content

[0004] In view of this, the present invention provides an interdigitated wire clamp that can handle overheating faults faster and better without replacing wires and equipment, saving materials while reducing the probability of overheating faults recurring and improving power supply reliability.

[0005] To achieve the above objectives, the present invention provides a forked-finger wire clamp, which includes a main contact surface and a wrap-around component. The main contact surface is provided with a plurality of screw holes, and the wrap-around component is located at one end of the main contact surface, forming a forked-finger wrap-around structure.

[0006] Preferably, the wrap-around component includes a semi-curved contact surface and a plurality of finger contact surfaces, wherein the plurality of finger contact surfaces are respectively disposed on both sides of the semi-curved contact surface, and the finger contact surfaces on one side and the finger contact surfaces on the other side of the semi-curved contact surface are arranged crosswise along the length direction of the semi-curved contact surface.

[0007] Preferably, one side of the semi-curved contact surface has two finger contact surfaces and the other side has one finger contact surface.

[0008] Preferably, the two sides of the semi-curved contact surface are provided with two finger contact surfaces.

[0009] Preferably, three or more finger contact surfaces are provided on each side of the semi-curved contact surface.

[0010] Preferably, the main contact surface is a copper plate or an aluminum plate.

[0011] Preferably, the main contact surface is a copper-aluminum transition plate.

[0012] Preferably, the encapsulated component is a copper plate or an aluminum plate.

[0013] Preferably, the encapsulated component is a copper-aluminum transition plate.

[0014] As can be seen from the above technical solution, compared with the prior art, the interdigitated clamp provided by this utility model has one end connected to the equipment terminal, and the other end wrapped around another equipment clamp crimping rod in an interdigitated manner to achieve double-sided connection. The main contact surface contacts the energized equipment terminal, and the two sides of the equipment terminal contact the two clamps (interdigitated clamp and original equipment clamp) respectively, so that the current is split from both sides to the clamp crimping rod, increasing the contact area between the clamp and the equipment terminal. Then the connecting wire of the original equipment clamp crimping rod is connected to the load to reduce the heat generation at the connection between the clamp and the equipment terminal, thereby solving the problem of power transmission failure caused by overheating faults in the market more quickly and effectively.

[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. The following description of an exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see the appendix Figure 1-4 This is the interdigitated wire clamp disclosed in this utility model.

[0023] like Figure 1-2 As shown, the interdigitated clamp provided by this utility model includes a main contact surface 1 and a wrap-around component. The main contact surface 1 is the part that connects the interdigitated clamp to the equipment terminal 5. Its specifications are the same as those of the original equipment clamp 6. The main contact surface 1 is provided with a number of screw holes 3. The specifications and number of screw holes 3 are the same as those of the original equipment clamp 6, so as to realize the connection between the main contact surface 1, the equipment terminal 5, and the original equipment clamp 6. The wrap-around component is located at one end of the main contact surface 1.

[0024] Specifically, such as Figure 3-4 As shown, in actual use, the wrap-around component is located at one end close to the wire crimping rod of the original equipment clamp 6. The wrap-around component forms a forked wrap-around structure, which is staggered and wrapped around the hydraulic wire rod assembly of the original equipment clamp 6 like interlaced fingers.

[0025] The wrap-around component includes a semi-curved contact surface 4 and several finger contact surfaces 2. The several finger contact surfaces 2 are respectively disposed on both sides of the semi-curved contact surface 4. The finger contact surfaces 2 on one side of the semi-curved contact surface 4 and the finger contact surfaces 2 on the other side are arranged crosswise along the length direction of the semi-curved contact surface 4.

[0026] The finger contact surface 2 is arc-shaped like a finger and is used for current diversion and connection with the crimping part of the device wire clamp rod. It is fastened to the original device wire clamp 6 rod by one or two crimping.

[0027] In use, the semi-circular contact surface 4 is wrapped around the bottom of the original equipment clamp 6 to shunt current. It is simultaneously crimped once or twice onto another clamp's connecting rod by the finger contact surface 2. The number of finger contact surfaces 2 depends on the length of the crimped portion of the original equipment clamp 6; for example, three or more finger contact surfaces 2 may be provided on each side of the semi-circular contact surface 4.

[0028] In this embodiment, as Figure 1As shown, the semi-curved contact surface 4 has two finger contact surfaces 2 on one side and one finger contact surface 2 on the other side.

[0029] In another embodiment, such as Figure 2 As shown, the semi-curved contact surface 4 has two finger contact surfaces 2 on both sides.

[0030] The main contact surface 1 is a copper plate, an aluminum plate, or a copper-aluminum transition plate, and the encapsulated component is a copper plate, an aluminum plate, or a copper-aluminum transition plate.

[0031] When traditional single-sided wire clamps overheat, after a power outage, the connecting screws are loosened and the original equipment wire clamp 6 (single-sided wire clamp) is removed. Then, the oxide layer on the contact surfaces of the original equipment wire clamp 6 and the equipment terminal 5 is removed with a grinder, conductive grease is applied, and then the connection is tightened. This process leaves a hidden danger of re-overheating. After the oxide layer is removed by the grinder, the surfaces of the equipment terminal 5 and the original equipment wire clamp 6 are rough, resulting in uneven contact. The conductive grease will also dry and crack due to sun exposure, losing its conductivity and easily causing overheating again. Furthermore, most wire connections to the equipment terminal 5 use crimp-type single-sided wire clamps, which cannot be replaced individually. Modern crimping tools are now mostly electro-hydraulic, so wire clamps using hydraulic rods are more common. Some wire connections to equipment do not have a pre-existing length (due to the curvature of the wiring). Therefore, simply replacing the single-sided wire clamp is insufficient; sometimes the entire wire must be replaced, leading to prolonged power outages, complex work, and significant material waste. Moreover, the grinding process can easily cause re-overheating.

[0032] The method of using the forked-finger clamp of this utility model is as follows: After applying conductive paste to the original equipment clamp 6, select a forked-finger clamp with the same specifications for the main contact surface 1 as the original equipment clamp 6. The size and spacing of the connecting holes of the forked-finger clamp are the same as those of the original equipment clamp 6. Place the original equipment clamp 6 on top of the equipment terminal 5, and place the forked-finger clamp below the equipment terminal 5. Connect and tighten with screws so that the equipment terminal 5 is clamped between the original equipment clamp 6 and the forked-finger clamp. Since the finger contact surface 2 of the forked-finger clamp is a foldable and unfoldable open structure, after the bottom of the forked-finger clamp matches the bottom of the original equipment clamp 6, the finger contact surface 2 is wrapped around the wire crimping rod of the original equipment clamp 6 for initial or secondary crimping (new installation or maintenance), so that all the finger contact surfaces 2 have good contact and are firmly secured with the wire crimping rod of the original equipment clamp 6.

[0033] Depending on the length of the wire crimping rod of the clamp, it can be three, four or more fingers. This method enables the double-sided connection of the equipment terminal 5, thereby guiding the load current from both sides of the equipment terminal 5 to the wire crimping rod, reducing the occurrence of overheating faults at the connection between the traditional equipment terminal 5 and the original equipment clamp 6, and enhancing mechanical strength.

[0034] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
