Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically to a conductive clamp. Background Technology

[0002] Currently, conductive clamps are widely used in various electrical connection scenarios for connecting various electrical equipment and lines. Traditional conductive clamps typically consist of an upper clamping body and a lower clamping body, which open and close via a pivot and a torsion spring to clamp conductive components and ensure a good electrical connection.

[0003] However, commonly used conductive clamps have many limitations. Their clamping jaws are poorly adaptable to conductive components of different specifications or shapes. Because the clamping jaws are usually fixed structures, they cannot provide stable and reliable clamping force when dealing with small conductive components such as fiber wires or foils, as well as other easily detachable conductive components. Conventional conductive clamps may cause indentations, deformation, or other damage to the surface of precision parts when gripping them, especially for some precision parts made of softer metals or plastics. This can lead to poor contact and affect conductivity. In addition, the front end of the clamp or other parts may be too heavy or too light, resulting in a poor feel. This can cause significant hand fatigue, especially when using conductive clamps for extended periods. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a conductive clip, including a clip assembly consisting of an upper clip and a lower clip. A rotating shaft is provided between the upper and lower clips, and two lugs are rotatably connected to both ends of the rotating shaft. The two lugs at the ends of the rotating shaft are fixedly connected to the upper and lower clips, respectively. A torsion spring is sleeved on the rotating shaft, and both ends of the torsion spring are in contact with the upper and lower clips, respectively. A small clamping groove is provided at the front end of the upper and lower clips, and a detachable toothed disc is installed in the small clamping groove.

[0005] The small clamping groove is provided with a toothed plate at its rear end;

[0006] The clamp assembly is equipped with a counterweight.

[0007] The present invention is further configured such that the small clamping groove is cylindrical and has a snap-fit ​​hole.

[0008] The present invention is further configured such that the detachable gear plate is connected to the small clamping groove by bolts.

[0009] The present invention is further configured such that: the tail end of the upper clamp is provided with an integrally formed handle.

[0010] The present invention is further configured such that: the lower clamp body has an integrally formed grip rod at its tail end.

[0011] The present invention is further configured such that the counterweight is placed inside the grip bar.

[0012] The present invention is further provided that the handle and grip are equipped with insulating sleeves.

[0013] The present invention is further configured such that the upper clamp, lower clamp, toothed disc, and toothed plate are all made of copper alloy.

[0014] In summary, this utility model has the following beneficial effects: This utility model discloses a conductive clamp, comprising a clamp assembly consisting of an upper clamp body and a lower clamp body, connected by a rotating shaft. A torsion spring is sleeved on the rotating shaft. The front ends of the upper and lower clamp bodies are provided with small clamping slots for mounting detachable toothed discs. A toothed plate is provided at the rear end of the small clamping slots. The toothed discs are easily replaceable for different needs, such as fiber threads, foil sheets, and other easily detachable conductive components, thereby reducing damage when clamping precision parts.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1As shown, this utility model discloses a conductive clamp, including a clamp assembly 3, which consists of an upper clamp 1 and a lower clamp 2. The upper clamp 1 and lower clamp 2 are provided with lugs 7, and a rotating shaft 6 is provided between the lugs 7. A torsion spring 8 is sleeved on the rotating shaft 6, and its two ends are in contact with the upper and lower clamps. The conductive clamp can open and close elastically and has a stable clamping force. The front ends of the upper clamp 1 and lower clamp 2 are provided with cylindrical small clamping grooves 10, and the small clamping grooves 10 are provided with snap-fit ​​holes 11. A toothed disc 20 is connected to the small clamping grooves 10 by bolts and placed within the small clamping grooves 10. In aerospace, high-end electronic equipment and other fields, carbon fiber filaments and metal foils are often difficult to hold stably when they need to be locally processed or treated. Conventional clamping methods can easily lead to displacement or wrinkling of the copper foil. However, the toothed disc 20 can provide a stable clamping solution. The toothed disc 20 has a larger contact area with the precision parts. When the conductive clamp picks up the precision parts, the same clamping force is distributed over a larger contact area, thereby reducing the pressure per unit area and reducing mechanical damage such as indentations and deformation to the surface of the parts.

[0022] like Figures 3-4 As shown, the toothed disc 20 is detachable. When the toothed disc 20 becomes worn or damaged, it can be replaced in a timely manner to ensure that the conductive clamp is always in good condition to grip precision parts. The shape of the teeth on the toothed disc 20 can also be adjusted according to different clamping requirements. When it is necessary to clamp cables, a multi-toothed toothed disc can be used. Figure 3 As shown, when it is necessary to clamp foil-like materials, a planar toothed disc can be used. Figure 4 As shown, the toothed plate 30 at the rear end of the small clamping groove 10 is suitable for conventional conductive materials, further expanding the clamping range.

[0023] Reference Figure 1-3 The upper clamp 1 has an integrally formed handle 50 at its tail end, and the lower clamp 2 has an integrally formed grip 51 at its tail end. A counterweight 52 is placed inside the grip 51, allowing the user to open and close the conductive clamp more conveniently while saving effort. When operating, the user simply presses the handle 50 with their finger, and in conjunction with the grip 51, easily overcomes the spring force of the torsion spring 8, causing the upper clamp 1 and lower clamp 2 to separate, thus opening the conductive clamp. After releasing the handle 50, under the action of the torsion spring 8, the upper clamp 1 and lower clamp 2 quickly close, completing the clamping operation. This reduces the difficulty of operation and hand fatigue, improves efficiency, and the counterweight 52 placed inside the grip 51 optimizes the overall center of gravity distribution of the conductive clamp, further enhancing operational stability and comfort.

[0024] like Figures 1-2As shown, both the handle 50 and the grip 51 are equipped with insulating sleeves 501. The insulating sleeves 501 are made of materials such as silicone rubber composite and polyimide. These high-performance insulating materials can effectively isolate current, ensure user safety, and prevent electric shock accidents.

[0025] In addition, the upper clamp 1, lower clamp 2, toothed disc 20, and toothed plate 30 are all made of copper alloy. Copper alloy has excellent electrical and thermal conductivity, as well as high strength and toughness, which makes the upper clamp 1, lower clamp 2, toothed disc 20, and toothed plate 30 less prone to deformation and damage during long-term use, ensuring the stability and reliability of the conductive clamp structure and extending its service life.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
