[0038] Referring to Figures 1 to 4, an embodiment of the utility model provides a multifunctional pliers for wire harnesses, including a clamping assembly 100 and a gripping assembly 200. The clamping assembly 100 includes two rotatably connected clamping members 110, and the clamping members 110 have abutment portions 111. Under the action of an external force, a pair of abutment portions 111 move toward or away from each other, and together form a clamping structure suitable for clamping a wire harness. The gripping assembly 200 includes two rotatably connected gripping members 210, and the gripping members 210 are correspondingly connected to the clamping members 110. Among them, a pair of clamping members 110 are rotatably connected through a first pivot 120, and a pair of gripping members 210 are rotatably connected through a second pivot 220. The first pivot 120 and the second pivot 220 are hollow structures, and a positioning pin is passed through the first pivot 120 and the second pivot 220 to fix the connection.
[0039] The multifunctional pliers for wire harnesses are provided with two rotatably connected clamping members 110, and the abutting portions 111 of the clamping members 110 can move toward or away from each other under the action of external force, and together form a clamping structure suitable for clamping the wire harness, which can ensure the stability of the wire harness when being clamped, and is not easy to slide or loosen, thereby improving the accuracy and safety of the operation. The gripping assembly 200 includes two rotatably connected gripping members 210, which are connected to the clamping members 110 accordingly.
[0040] The hollow structure of the first pivot 120 and the second pivot 220 ensures that they can be precisely aligned through the positioning pins, thereby achieving coaxial rotation. This design can effectively avoid the situation where the two pivots are out of sync or deviate during the rotation process, and ensure the synchronous movement of the clamping member 110 and the gripping member 210, making the tool more stable during use, with less deformation under long-term use or high clamping force conditions, and higher operating accuracy. The design of the hollow structure allows the positioning pins to be easily inserted and fixed, thereby simplifying the assembly and disassembly process of the tool, and making it easier to replace clamping assemblies 100 of different specifications. This not only makes the tool more convenient during the production process, but also facilitates later repairs and replacements, improving the maintainability of the tool.
[0041] Referring to FIG. 2 , in one embodiment, the clamping member 110 further includes a base plate 112, and the abutting portion 111 is disposed at one end of the base plate 112 and extends in a direction away from the base plate 112, and the extending direction of the abutting portion 111 is not coplanar with the plane where the base plate 112 is located. Specifically in this embodiment, the abutting portion 111 extends in a direction away from the base plate 112 and then bends, that is, forms an L-shaped structure with the base plate 112. The L-shaped structure can increase the contact area of the clamped wire harness and avoid damage to the wire harness during disassembly and assembly.
[0042] The L-shaped structure can greatly increase the contact area when clamping the wire harness. The increased contact area can disperse the pressure applied to the wire harness, reduce the uneven force on the wire harness, and effectively prevent the wire harness from being damaged due to concentrated force. Since the L-shaped structure can provide a larger area of support when clamping the wire harness, the stability of the wire harness during the clamping process is significantly improved. This stability is crucial for the operation of the wire harness, especially during the disassembly and assembly process. When the wire harness is stably supported, it is not easy to slide or shift, which improves the accuracy of the operation. The L-shaped structure can provide a more uniform pressure distribution during the clamping process, reduce the pressure and extrusion on the wire harness, and effectively prevent the wire harness from being damaged by the clamping member 110. This design is particularly suitable for occasions where frequent disassembly and assembly are required or the quality of the wire harness is high, ensuring that the wire harness is not damaged during operation. The design of the L-shaped structure not only improves the clamping effect, but also facilitates manipulation. When using the tool, the operator can flexibly control the movement of the clamping member 110 by adjusting the force and angle of the grip assembly 200, so as to clamp and operate the wire harness more accurately. This design improves the operating comfort and flexibility of the tool.
[0043] Referring to FIG. 2 , in one embodiment, the abutting surfaces of a pair of abutting portions 111 are planes. The abutting surfaces of the abutting portions 111 are planes, which can provide uniform clamping force when clamping the wire harness. Compared with abutting surfaces with curved surfaces or other irregular shapes, the plane design can ensure a more uniform distribution of force during the clamping process, avoid local excessive force, and thus reduce damage to the wire harness. The planar abutting surface provides a larger contact area, so that the clamping member 110 can be more stable when clamping the wire harness. Large area contact can effectively increase friction, prevent the wire harness from sliding or shifting during the clamping process, and ensure the stability and safety of the operation. The planar abutting surface design has a wide range of adaptability and can clamp wire harnesses of different specifications and shapes. Whether it is a thin wire harness or a thick wire harness, the planar abutting surface can provide a good clamping effect, increasing the scope of application and flexibility of the tool.
[0044] Referring to FIG. 3 , in one embodiment, an anti-skid structure 113 is provided on the abutment portion 111 , and the anti-skid structure 113 includes a plurality of slots arranged according to a preset rule. The slots are arranged according to a preset rule, so that the clamping surface has a consistent anti-skid effect. This regularly arranged slot design can provide a uniform friction force distribution, so that the wire harness can be subjected to the same anti-skid effect at different positions, thereby ensuring the accuracy and consistency of the operation. The anti-skid slot design can increase the friction force while reducing damage to the surface of the wire harness. Compared with rough or sharp anti-skid designs, regularly arranged slots can provide a mild anti-skid effect, reduce wear and extrusion on the insulation layer of the wire harness, and protect the integrity of the wire harness. The anti-skid slot structure can adapt to wire harnesses of different diameters and surface materials, and can provide a good anti-skid effect for both smooth plastic insulated wire harnesses and braided wire harnesses. The scope of application of the multi-functional pliers is enhanced, so that it can perform well in various wire harness operations.
[0045] Referring to FIGS. 1 to 3 , in one embodiment, a first positioning assembly 300 is further included. The first positioning assembly 300 includes a first positioning structure 310 disposed on the clamping member 110 and a first matching structure 320 disposed on the gripping member 210. The first positioning structure 310 is disposed on a side of the first pivot 120 close to the abutment portion 111, and the first matching structure 320 is disposed correspondingly to the first positioning structure 310. The positioning assembly can ensure that the clamping member 110 and the gripping member 210 maintain an accurate relative position during operation, and avoid the clamping member 110 from being offset during use, thereby improving the clamping accuracy. The first positioning structure 310 is disposed on a side of the first pivot 120 close to the abutment portion 111, and the first matching structure 320 is disposed correspondingly to the first positioning structure 310. This design can provide additional support and constraint when external force is applied, enhance the stability of the overall structure, and prevent the clamping member 110 and the gripping member 210 from being loosened or misaligned during operation. The positioning assembly not only ensures the clamping accuracy, but also improves the safety of operation. Especially in high-load or delicate operations, the positioning assembly can prevent the clamping member 110 from accidentally loosening due to uneven force or external interference, thereby ensuring the continuity and safety of the wiring harness operation.
[0046] Referring to FIGS. 1 to 3 , in one embodiment, a second positioning assembly 400 is further included. The second positioning assembly 400 includes a second positioning structure 410 disposed on the clamping member 110 and a second matching structure 420 disposed on the gripping member 210. The second positioning structure 410 is disposed on a side of the second pivot 220 away from the abutment portion 111, and the second matching structure 420 is disposed corresponding to the second positioning structure 410. By arranging the positioning assemblies at different positions of the two pivots, more comprehensive support and constraint are provided. This design can effectively prevent any relative movement or dislocation of the clamping member 110 and the gripping member 210 during operation, significantly enhancing the overall structural stability of the tool. The introduction of the second positioning assembly 400 further improves operational safety. The dual positioning design provides additional safety protection, which can effectively prevent the clamping member 110 from accidentally loosening or dislocating even in high-load operation or complex environments, ensuring the continuity and safety of the wiring harness operation. The dual positioning assembly shares the mechanical load during use, reduces the direct contact and friction between the clamping member 110 and the gripping member 210, and thus reduces the wear rate. At the same time, this design can also reduce tool fatigue during long-term use and significantly extend its service life.
[0047] Referring to FIGS. 1 to 3 , in one embodiment, the first positioning structure 310 is a protruding structure, and the first matching structure 320 is a groove structure; or the first positioning structure 310 is a groove structure, and the first matching structure 320 is a protruding structure. Specifically, in this embodiment, the first positioning structure 310 is a groove structure, and the first matching structure 320 is a protruding structure. Through the snap-fitting of the protruding structure and the groove structure, the gripping assembly 200 and the clamping assembly 100 are positioned and connected on the side close to the abutting portion 111.
[0048] Referring to FIGS. 1 to 3 , in one embodiment, the second positioning structure 410 is a protruding structure, and the second matching structure 420 is a groove structure; or the second positioning structure 410 is a groove structure, and the second matching structure 420 is a protruding structure. Specifically, in this embodiment, the second positioning structure 410 is a groove structure, and the second matching structure 420 is a protruding structure. Through the snap-fitting of the protruding structure and the groove structure, the gripping assembly 200 and the clamping assembly 100 are positioned and connected on the side away from the abutting portion 111.
[0049] By providing a protrusion structure and a groove structure on both sides close to and away from the abutment portion 111, respectively, the dual positioning structure design provides a more accurate and stable positioning connection. This design ensures the stability and accurate alignment of the gripping assembly 200 and the clamping assembly 100 during the entire operation process, preventing the components from being misaligned and loose. The snap-fit design of the dual positioning structure allows the operator to align and fix the tool more quickly, improving the efficiency of disassembly and assembly of the wiring harness connector. This design reduces adjustment time and operational complexity, and improves overall work efficiency.
[0050] It should be noted that the above two embodiments do not limit the specific groove and protrusion structure settings of the first positioning structure 310, the first matching structure 320, the second positioning structure 410 and the second matching structure 420, and are based on the realization of two-by-two snap connection between the first positioning structure 310 and the first matching structure 320, and the second positioning structure 410 and the second matching structure 420.
[0051] Referring to Figures 1 to 3, in one embodiment, the protrusion structure includes a first protrusion and a second protrusion, the second protrusion is arranged on the first protrusion, and the diameter of the second protrusion is smaller than the diameter of the first protrusion. Specifically in this embodiment, the first protrusion and the second protrusion are coaxially arranged columnar steps, and the second protrusion is arranged on the upper end surface of the first protrusion, which mainly plays a positioning role. The first protrusion is connected to the substrate 112 as the base of the protrusion structure. Since the diameter of the first protrusion is larger, it mainly bears the connection force with the groove structure.
[0052] The first protrusion serves as a base with a larger diameter, which can provide a larger contact area and stronger support force, and bear the main connection force. Although the second protrusion is smaller, it provides additional positioning support by embedding the groove structure. The double-layer structure cooperates with each other, making the overall connection more stable and reducing the possibility of loosening and displacement. The larger diameter of the first protrusion enables it to withstand greater force and evenly distribute the force to the substrate 112 to prevent damage caused by excessive local force. The second protrusion is mainly responsible for positioning, which reduces its own force pressure while achieving precise alignment. This layered force design effectively improves the durability and reliability of the tool.
[0053] Since the first protrusion has a larger diameter, it provides a larger contact area and higher friction when connected with the groove structure, making the connection more stable and preventing loosening or falling off during operation. The second protrusion is embedded in the groove to achieve preliminary positioning, ensuring accurate alignment during connection; the first protrusion further provides stable support and connection. The double-layer positioning effect not only improves the accuracy of the connection, but also increases the stability and safety of the operation.
[0054] In one of the embodiments, the surface of the grip 210 is covered with an insulating layer. The grip 210 surface is covered with an insulating layer, which can effectively prevent the operator from getting an electric shock when handling a live wire harness. The insulating layer provides an additional safety barrier to ensure safe operation in various working environments, especially in scenarios involving electrical work. The insulating layer is usually made of a soft material with a good grip, which can improve the comfort of the grip 210. When using the tool, the operator can feel a more comfortable grip experience and reduce hand fatigue caused by long-term operation. Many insulating materials also have anti-slip properties, which allows the grip 210 to maintain a good grip even in a humid or greasy environment. The anti-slip grip 210 can reduce the risk of the tool slipping during operation and improve the stability and safety of the operation.
[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
