Description

Technical Field

[0001] This utility model relates to the field of wiring pliers technology, and in particular to a wiring pliers for electrical engineering. Background Technology

[0002] Electrical engineering is a general term encompassing disciplines or engineering fields such as the production, transmission, distribution, and use of electrical energy and the manufacturing of electrical equipment. It is a science that uses electrical energy, electrical equipment, and electrical technology to create, maintain, and improve a defined space and environment. Among these, wiring pliers are specialized tools used for temporary wiring when testing or repairing electrical equipment. When electrical equipment and lines malfunction, wiring pliers are often required to repair the lines and equipment.

[0003] Before connecting cables, the insulation layer at one end needs to be stripped to expose the metal conductors. However, existing wire stripping pliers often have fixed-size blades. During use, the cable is inserted into the blades and squeezed to cut it. However, controlling the squeezing force is difficult. Excessive force can scrape or cut the cable core, causing unnecessary waste and potentially causing the blades to become worn. Insufficient force fails to effectively remove the insulation layer, making it inconvenient to use. Therefore, we provide a wire stripping pliers for electrical engineering that solves these problems. Utility Model Content

[0004] This utility model proposes a wiring pliers for electrical engineering. By setting a sleeve, a slide rod, and a first spring on the inner walls of the first and second clamp bodies, the slide rod is connected to the slider. An arc-shaped blade is installed on the slider. The elastic deformation of the first spring automatically adjusts the spacing of the arc-shaped blade according to the cable size, thereby solving the problems of difficulty in controlling the squeezing force when stripping wires with existing wiring pliers, easy damage to the inner core of the cable, and chipping of the stripping blade.

[0005] A wiring clamp for electrical engineering includes a first clamp body and a second clamp body, which are hinged together by a pin.

The other end of the first spring, the sliding rod, and the slider are sequentially fixedly connected. Both the sliding rod and the slider are slidably connected inside the sleeve. An arc-shaped blade for cutting cable insulation is installed on the outer side of the slider. The arc-shaped blades on the first and second clamp bodies are arranged opposite each other.

[0006] Furthermore, when not in use, the curved blade protrudes from the opening of the sleeve.

[0007] Furthermore, the distance by which the curved blade protrudes from the opening of the sleeve is slightly greater than the maximum compression length of the first spring.

[0008] Furthermore, a fixing rod is fixedly connected to the outer surface of both the first clamp and the second clamp, and a second spring is provided between the first clamp and the second clamp, with the second spring sleeved on the outer surface of the fixing rod.

[0009] Furthermore, the outer surfaces of both the first and second clamps are provided with several anti-slip protrusions to improve the clamping stability of the wiring clamps.

[0010] Furthermore, the outer surfaces of the first clamp and the second clamp are provided with arc-shaped slots to improve the clamping stability of circular objects, and the outer surface of the arc-shaped slots is provided with a number of grooves equidistantly arranged along the arc surface of the arc-shaped slots.

[0011] Furthermore, the first clamp body is hinged to a connecting hook via a pin, and the second clamp body is fixedly connected to a limit rod on the same side as the connecting hook, and the connecting hook is adapted to the limit rod.

[0012] Furthermore, both the first clamp and the second clamp have several bolt-tightening through holes for tightening bolts of different sizes.

[0013] Furthermore, both the first and second clamp bodies are provided with reserved holes to facilitate the hanging and carrying of the wiring clamps.

[0014] Furthermore, the outer surfaces of both the first and second clamp bodies are provided with several anti-slip grooves to improve the stability of the clamps when gripped.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] As described in the background art, the stripping part of existing wire crimping pliers is mostly a fixed-size blade. When in use, the cable is inserted into the stripping blade and squeezed to cut it. However, it is not easy to control the squeezing force. When the squeezing force is too large, it is easy to scrape or cut the inner core of the cable, causing unnecessary waste and easily causing the stripping blade to bend. When the squeezing force is too small, it is not possible to effectively remove the insulation layer, resulting in inconvenience in use. Therefore, this embodiment provides a wire crimping pliers for electrical engineering.

[0026] See Figures 1 to 5 This embodiment proposes a wiring clamp for electrical engineering, including a first clamp body 1, and a second clamp body 2 hinged to the outside of the first clamp body 1 by a pin. The first clamp body 1 and the second clamp body 2 are connected by the pin and combined into a wiring clamp for engineering, so that workers can temporarily connect wires when testing or repairing electrical equipment.

[0027] The outer surfaces of the first clamp body 1 and the second clamp body 2 are each fixedly connected with a number of anti-slip protrusions 10 to improve the clamping stability of the wiring pliers. By setting the anti-slip protrusions 10, the stability of the wiring pliers used in electrical engineering when clamping objects can be improved. The anti-slip protrusions 10 can be integrally molded with the first clamp body 1 and the second clamp body 2 at the corresponding positions.

[0028] A fixing rod 8 is fixedly connected to the outer surface of both the first clamp body 1 and the second clamp body 2. A second spring 9 is provided between the first clamp body 1 and the second clamp body 2, and the second spring 9 is sleeved on the outer surface of the fixing rod 8. By setting the fixing rod 8 and the second spring 9, it is convenient to reset the electrical engineering wiring pliers after they have been squeezed, thereby improving the convenience of use.

[0029] Both the first clamp body 1 and the second clamp body 2 have arc-shaped slots 11 on their outer surfaces to improve the stability of clamping round objects. The outer surface of the arc-shaped slots 11 has several grooves arranged at equal intervals along the arc surface of the arc-shaped slots 11. By setting the arc-shaped slots 11, it is convenient to use electrical engineering wiring pliers to clamp and fix round objects, and the grooves can improve the stability of the electrical engineering wiring pliers when clamping round objects.

[0030] The front of the first clamp body 1 is hinged with a connecting hook 12 via a pin. The front of the second clamp body 2 is fixedly connected with a limiting rod 13, and the connecting hook 12 is adapted to the limiting rod 13. The connecting hook 12 is locked onto the outer surface of the limiting rod 13, which can close the unused electrical engineering wiring pliers, thereby preventing the clamp body from rotating randomly and damaging other items while the staff is carrying the clamp body.

[0031] The inner walls of the first clamp body 1 and the second clamp body 2 are each fixedly connected to two sleeves 3. The inner wall of each sleeve 3 is slidably connected to a slide rod 4. The inner wall of each sleeve 3 is fixedly connected to a first spring 5, and the slide rod 4 is fixedly connected to the first spring 5. The inner walls of the first clamp body 1 and the second clamp body 2 are each slidably connected to two sliders 6, and the slide rod 4 is fixedly connected to the sliders 6. The inner wall of each slider 6 is equipped with an arc-shaped blade 7 for cutting the insulation layer of the cable.

[0032] When stripping the insulation layer from the surface of the cable using electrical engineering pliers, the cable can be placed between two curved blades 7. Then, the first clamp body 1 and the second clamp body 2 are brought closer to each other, so that the curved blades 7 come into contact with and squeeze the outer surface of the cable to complete the cutting.

[0033] Then, by continuing to control the first clamp 1 and the second clamp 2 to move closer to each other, the arc-shaped blade 7 can drive the slider 6 to slide along the inner wall of the first clamp 1 and the second clamp 2 at the corresponding positions, thereby driving the slide rod 4 to slide along the inner wall of the sleeve 3 and compressing the first spring 5 to produce elastic deformation. Then, by utilizing the reset effect of the first spring 5, the arc-shaped blade 7 can be tightly attached to the cable insulation layer. At the same time, it avoids that the inner core of the cable may be easily scraped or cut when the squeezing force is too large, causing unnecessary waste and easily causing the stripping blade to bend. It also avoids that the insulation layer cannot be effectively stripped when the squeezing force is too small, which would make it inconvenient to use.

[0034] The arc-shaped blade 7 protrudes from the opening of the sleeve 3, and the distance between the arc-shaped blade 7 and the opening of the sleeve 3 is slightly greater than the maximum compression length of the first spring 5. This design takes into full account potential situations that may arise during actual use. When using the connector clamps to strip the insulation of a cable, as the first clamp body 1 and the second clamp body 2 move closer together, the arc-shaped blade 7 gradually applies pressure to the cable. During this process, the first spring 5 is compressed by the pressure transmitted by the slide rod 4. If the distance between the arc-shaped blade 7 and the opening of the sleeve 3 is not properly designed, and the arc-shaped blade 7 is completely pressed into the sleeve 3, it is highly likely that the cable insulation will not be cut. This is because some cable insulation is aged and hardened, so this situation cannot be ruled out. In actual insulation stripping operations, when the first spring 5 reaches its maximum compression state, if the arc-shaped blade 7 is completely embedded in the sleeve 3 at this point, its cutting force on the cable insulation will be greatly weakened, or even unable to continue cutting, resulting in inability to properly strip the insulation and affecting the effectiveness of the connector clamps. Therefore, ensuring that the arc-shaped blade 7 remains slightly outside the sleeve 3 even when the first spring 5 reaches its maximum compression is one of the key design considerations to ensure that the connector clamp can stably and efficiently complete the cable insulation stripping operation.

[0035] The front of both the first clamp body 1 and the second clamp body 2 is provided with several bolt tightening through holes 14 for tightening bolts of different sizes. The bolt tightening through holes 14 can be consistent with several bolt sizes commonly used in electrical engineering, so as to facilitate the tightening of bolts of the corresponding size during use and improve the stability during use.

[0036] Both the first clamp body 1 and the second clamp body 2 have reserved holes 15 on their front sides to facilitate the hanging and carrying of the wiring pliers. By setting the reserved holes 15, the wiring pliers for electrical engineering can be easily hung, and the wiring pliers for electrical engineering can be easily carried by passing the connecting rope through the reserved holes 15.

[0037] The outer surfaces of the first clamp body 1 and the second clamp body 2 are provided with a number of anti-slip grooves 16 to improve the stability of the clamp when holding it. By setting the anti-slip grooves 16, the friction force of the worker holding the electrical engineering clamp can be increased, thereby improving the stability of the worker holding the electrical engineering clamp.

[0038] The components in the accompanying drawings of this utility model are for styling reference only and are not marked with specific dimensions. The specific dimensions are determined according to the actual production requirements, and the materials of each component can be replaced accordingly as needed.

[0039] Working principle: When using electrical engineering wire strippers to remove the insulation layer from the surface of a cable, the worker places the cable between two curved blades 7. The worker then holds the first clamp body 1 and the second clamp body 2 close together, causing the two curved blades 7 to contact and squeeze the outer surface of the cable to complete the cut. After the two curved blades 7 contact the cable, they continue to move closer together, causing the slider 6 to slide along the inner wall of the first clamp body 1 and the second clamp body 2 at corresponding positions. This, in turn, causes the sliding rod 4 to slide along the inner wall of the sleeve 3, compressing the first spring 5. The elastic deformation generates a return effect, which allows the arc-shaped blade 7 to fit tightly against the cable insulation layer to achieve the cutting purpose. At the same time, it avoids the cable core being easily scraped or cut when the squeezing force is too large, causing unnecessary waste and easily causing the stripping blade to bend. It also avoids the insulation layer not being effectively removed when the squeezing force is too small. As a result, the operator of the wiring pliers does not need to consider the clamping force of the cable. They can simply insert the cable into the stripping blade and squeeze and cut it with greater force, thereby improving the convenience and practicality of the wiring pliers.

[0040] The electrical engineering connector pliers proposed in this utility model feature a unique combination structure of sleeve 3, slide bar 4, and first spring 5. This structure automatically and precisely adjusts the distance between the two arc-shaped blades 7 according to the size of the cable. Users no longer need to carefully control the squeezing force; they can directly apply a larger pressure to strip the wire. This avoids waste caused by excessive squeezing force that could cut or scrape the inner core of the cable, prevents the stripping blades from becoming dull, and eliminates the situation where insufficient squeezing force fails to effectively remove the insulation layer. This greatly improves the convenience and practicality of the connector pliers. In terms of structural design, the combination of the fixing rod 8 and the second spring 9 allows the connector pliers to easily return to their original position after squeezing, improving operating efficiency. The anti-slip protrusions 10 increase the friction when the connector pliers grip objects, making them more stable when gripping various items. The arc-shaped slot 11 and its surface grooves are specifically designed for gripping round objects, further enhancing the fixation effect on such objects. In addition, the connecting hook 12 and the limiting rod 13 are compatible and can be closed when the wire cutters are not in use, preventing the pliers from rotating randomly and damaging other items during carrying; multiple bolt tightening through holes 14 of different sizes make it convenient for users to tighten various bolts; the reserved hole 15 facilitates the hanging and carrying of the wire cutters; and the anti-slip groove 16 enhances the stability of the wire cutters when the staff holds them, thus comprehensively improving the overall performance of the product.

[0041] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of the utility model should be covered within the scope of the utility model.
