Description

Technical Field

[0001] The utility model relates to the technical field of electrician tools, in particular to an electrician wire stripping tool. Background Art

[0002] Cables are indispensable in automation control systems. There must be cables in the control lines that transmit automation control signals, such as control cables for equipment, acquisition cables for sensor data transmission, and connection cables for control cabinet power supply. An automation control project has dozens of cables at least, and hundreds or thousands of cables at most. In the process of using cables, it is inevitable to strip the cables. At present, the main way to strip cables is that engineers use electrician's knives to cut a knife edge parallel to the cable along the outer side of the cable skin to strip the cables. The stripping speed depends largely on the proficiency of the engineers, the stripping efficiency is low, and the stripping quality is uncontrollable. In addition, this stripping method is also easy to hurt the engineer's hand holding the cable. When the knife edge force is not well controlled, it is also easy to scratch the wires inside the cable, so that the insulation layer of the wire is damaged and the copper core of the wire is cut off, which eventually leads to a decrease in the cable protection and a quality accident with reduced current carrying capacity. It can be seen that the traditional method of stripping with electrician's knives has low stripping efficiency, and engineers are easily injured during the stripping process, and the wires inside the cable are easily damaged during the stripping operation, and the operation safety is poor.

[0024] Please refer to Figure 1 , which is a structural schematic diagram of an electrician's wire stripping tool provided in an embodiment of the utility model.

[0025] The utility model provides an electrician wire stripping tool, comprising:

[0026] An outer frame 1, wherein the outer frame 1 is in a hollow cylindrical shape, and the inner diameter of the outer frame 1 is larger than the outer diameter of the cable to be stripped;

[0027] The tool comprises a rocker arm 5, a strip cutter head 4 and an arc-shaped protective portion 7, one end of the rocker arm 5 is movably connected to the outer frame 1, the other end of the rocker arm 5 is connected to one end of the strip cutter head 4, the rocker arm 5 and the strip cutter head 4 form an angle of 100-150 degrees, a blade is arranged on the inner edge of the strip cutter head 4, the other end of the strip cutter head 4 is connected to the arc-shaped protective portion 7, the arc-shaped protective portion 7 extends toward the direction of the outer frame 1 and bends toward the rocker arm 5, the rocker arm 5, the strip cutter head 4 and the arc-shaped protective portion 7 enclose a U-shaped cavity.

[0028] Specifically, since cables have various specifications, cables of different specifications have different lengths, different diameters, or different outer skin thicknesses. Therefore, the electrician wire stripping tool provided in this embodiment also has various specifications accordingly. Electrician wire stripping tools of different specifications can correspond to outer frames 1 of different sizes, strip blades 4 of different lengths, swing rods 5 of different lengths, etc. Each specification of electrician wire stripping tool can strip cables within a certain specification range. During on-site operation, engineers can select electrician wire stripping tools of appropriate specifications according to the actual situation of the cable to be stripped.

[0029] Specifically, the diameters of different cables vary according to the purpose, electrical characteristics, carrying capacity, etc. of the cables. Cables of different specifications have different diameters to adapt to different application scenarios and requirements. In this case, an outer frame 1 with a suitable inner diameter can be selected, and then an electrician wire stripping tool of suitable specifications can be selected for wire stripping.

[0030] Specifically, the thickness of the outer skin of different cables will vary according to the purpose of the cable, environmental conditions and safety requirements. Cables of different specifications require outer skins of different thicknesses to protect the internal wires. In view of this situation, a strip cutter head 4 of appropriate length can be selected, and then an electrician wire stripping tool of appropriate specifications can be selected for wire stripping.

[0031] Specifically, when the electrician wire stripping tool is used for cable stripping, the outer frame 1 is placed horizontally and the strip blade 4 is placed vertically. Because the swing rod 5 and the outer frame 1 are at a certain angle, the strip blade 4 and the swing rod 5 form an angle of 100-150 degrees, so that the electrician wire stripping tool can adapt to the cable sheath within a certain specification range. The structure is simple, the overall stability is good, and the application range is wider.

[0032] When the electrician wire stripping tool provided in this embodiment is used to strip the cable, the cable is passed through the outer frame 1 from the side away from the strip cutter head 4 and gradually approaches the strip cutter head 4. The inner diameter of the outer frame 1 is larger than the outer diameter of the cable to be stripped, so that the cable can pass smoothly through the inner wall of the outer frame 1 and move back and forth, and a stable supporting force is given to the cable during the stripping process, so as to avoid the engineer manually holding the cable and not easily injuring his hands; the position of the cable break and the swing rod 5 is adjusted to make the cable break contact with the strip cutter head 4, and the contact depth between the blade and the cable skin is adjusted to ensure that the cable skin can be touched by the blade when stripping. The cable sheath is cut open thoroughly to achieve effective wire stripping, and at the same time, the arc-shaped protective part 7 penetrates into the cable sheath at the cable break, so that the cable sheath is firmly stuck in the U-shaped cavity, ensuring that the cable is not easily displaced during the stripping process and the stripping depth is consistent; the electrician's wire stripping tool is pulled to move along the direction of the cable to be stripped, so that the blade can easily break the cable sheath to complete the cable stripping, and the stripping efficiency is high. In addition, the arc-shaped protective part 7 can protect the wires in the cable from being scratched by the blade during the stripping process, effectively avoiding the problem of scratching the wires due to inconsistent force of the knife head, and greatly improving the safety and reliability of the stripping operation.

[0033] In some embodiments of the present application, the swing rod 5 and the strip cutter head 4 form an angle of 110 degrees.

[0034] Specifically, the swing arm 5 and the outer frame 1 form an angle of 20 degrees, the strip blade head 4 and the outer frame 1 form an angle of 90 degrees, and the strip blade head 4 and the swing arm 5 form an angle of 110 degrees to adapt to the specifications of common cables on the market.

[0035] In some embodiments of the present application, the electrician wire stripping tool also includes a first screw 6, the outer frame 1 is provided with a first thread matching the first screw 6, and one end of the rocker arm 5 is movably connected to the outer frame 1 through the first screw 6 and the first thread; when the first screw 6 rotates in one direction, the first screw 6 rises along the first thread, and the angle between the other end of the rocker arm 5 and the central axis of the outer frame 1 is reduced; when the first screw 6 rotates in another direction, the first screw 6 descends along the first thread, and the angle between the other end of the rocker arm 5 and the central axis of the outer frame 1 is enlarged.

[0036] Specifically, the first screw 6 is used to adjust the relative position of the cable break and the swing rod 5, and then adjust the relative position of the cable break and the strip cutter head 4, so that the cable break is in contact with the strip cutter head 4 while helping the cable skin to be firmly stuck in the U-shaped cavity, further expanding the specification range of cables that can be stripped by the electrician's wire stripping tool, and the scope of application is wider. It should be noted that when the one direction is clockwise, the other direction is counterclockwise; conversely, when the one direction is counterclockwise, the other direction is clockwise.

[0037] In some embodiments of the present application, the electrician wire stripping tool also includes a telescopic rod, one end of the telescopic rod is fixedly connected to the external frame 1, and the other end of the telescopic rod is fixedly connected to the rocker arm 5, and the telescopic rod is parallel to the first screw rod 6; when the angle between the other end of the rocker arm 5 and the central axis of the external frame 1 is reduced, the telescopic rod is shortened; when the angle between the other end of the rocker arm 5 and the central axis of the external frame 1 is enlarged, the telescopic rod is lengthened.

[0038] Specifically, the telescopic rod is used to cooperate with the position adjustment of the swing rod 5 and further improve the stability of the connection between the swing rod 5 and the outer frame 1.

[0039] In some embodiments of the present application, the distance from the telescopic rod to the strip cutter head 4 is smaller than the distance from the first screw rod 6 to the strip cutter head 4 .

[0040] Specifically, the telescopic adjustment range of the same telescopic rod is the same. However, when the telescopic rod is arranged in front of the first screw rod 6, compared with when the telescopic rod is arranged behind the first screw rod 6, the telescopic adjustment range of the telescopic rod that can be adjusted in coordination with the swing rod 5 is larger, and the position adjustment of the swing rod 5 can be better coordinated, and the flexibility is higher.

[0041] In some embodiments of the present application, the electrician wire stripping tool also includes a support rod, one end of the support rod is fixedly connected to the outer frame 1, the other end of the support rod is hinged to the rocker arm 5 through a pin shaft, and the support rod is parallel to the first screw rod 6; when the first screw rod 6 rises or descends along the first thread, one end of the rocker arm 5 gradually approaches or moves away from the outer frame 1, and drives the other end of the rocker arm 5 to gradually move away from or approach the central axis of the outer frame 1 with the pin shaft as the rotating axis.

[0042] Specifically, according to the lever principle, the swing rod 5 is equivalent to a lever, the pin of the support rod is equivalent to a rotating shaft, and the swing rod 5 generates a rotational motion around the pin. When the first screw rod 6 rises along the first thread, one end of the swing rod 5 gradually approaches the outer frame 1, and the other end of the swing rod 5 is driven to gradually move away from the central axis of the outer frame 1 with the pin as the rotating shaft; when the first screw rod 6 descends along the first thread, one end of the swing rod 5 gradually moves away from the outer frame 1, and the other end of the swing rod 5 is driven to gradually move toward the central axis of the outer frame 1 with the pin as the rotating shaft. The support rod is used to cooperate with the position adjustment of the swing rod 5 and further improve the stability of the connection between the swing rod 5 and the outer frame 1.

[0043] In some embodiments of the present application, the electrician's wire stripping tool also includes a second screw 2, the outer frame 1 is provided with a second thread matching the second screw 2, and the outer frame 1 is connected to the second screw 2 through the second thread; when the second screw 2 rotates in one direction, the second screw 2 rises along the second thread, and the inner diameter of the outer frame 1 is enlarged; when the second screw 2 rotates in another direction, the second screw 2 descends along the second thread, and the inner diameter of the outer frame 1 is reduced.

[0044] Specifically, the second screw 2 is provided so that the inner wall of the outer frame 1 and the cable to be stripped can be in more stable and uniform contact. After adjustment of the second screw 2, the contact between the cable to be stripped and the inner wall will not be too tight to hinder the forward and backward movement of the cable to be stripped, nor will it be too loose to provide a stable supporting force to the cable to be stripped. Moreover, the provision of the second screw 2 can further expand the range of cable specifications of different diameters that the electrician's wire stripping tool can strip, and has a wider range of applications. It should be noted that when the one direction is clockwise, the other direction is counterclockwise; conversely, when the one direction is counterclockwise, the other direction is clockwise.

[0045] Specifically, the second screw rod 2 can change the inner diameter of the outer frame 1 by rising and falling, or by moving forward and backward. The specific changing method can be designed according to the application of the electrician wire stripping tool, and will not be described here.

[0046] In some embodiments of the present application, the first screw rod 6 is disposed at the bottom of the outer frame 1 , and the second screw rod 2 is disposed at the top of the outer frame 1 .

[0047] Specifically, the first screw rod 6 and the second screw rod 2 are respectively arranged at the bottom and the top of the outer frame 1, so that the force of the outer frame 1 can be more uniform, and the service life of the outer frame 1 can be further extended. Of course, in actual application, the first screw rod 6 and the second screw rod 2 can also be arranged at other positions of the outer frame 1, as long as the corresponding adjustment purpose is achieved, and no further examples will be given here.

[0048] In some embodiments of the present application, the space enclosed by the outer wall and the inner wall of the outer frame 1 is a hollow cavity, the inner wall is provided with a plurality of through holes, a plurality of balls 3 are provided in the hollow cavity, the diameter of the balls 3 is larger than the diameter of the through holes, and each of the balls 3 protrudes from the inner wall through one of the through holes.

[0049] Specifically, when the cable to be stripped passes through the inner wall and moves forward and backward, the cable to be stripped contacts the ball 3 and drives the ball 3 to rotate. The provision of the ball 3 can reduce the friction force when the cable to be stripped passes through the inner wall of the outer frame 1, making the forward and backward movement of the cable to be stripped smoother. Furthermore, the ball 3 is a stainless steel ball with a smooth surface, which can further reduce the friction force during contact movement.

[0050] In some embodiments of the present application, at least four through holes are disposed on the inner wall, and at least four balls 3 are disposed in the hollow cavity.

[0051] Specifically, the four balls 3 can be symmetrically arranged at the upper, lower, left and right positions of the inner wall, so that the cable can be evenly stressed; or, considering that the contact area between the cable and the bottom of the inner wall is the largest, two balls can be arranged at the bottom, one on each side. The specific arrangement of the balls 3 depends on the actual situation, and will not be described here.

[0052] The following details the steps for stripping cables using this electrician's wire stripping tool:

[0053] 1. Let the cable break start from the side relatively far away from the strip cutter head 4, pass through the inner wall of the outer frame 1, come to the side relatively close to the strip cutter head 4, and continue to gradually approach the strip cutter head 4;

[0054] 2. Adjust the second screw 2 to make the cable in good contact with the inner wall of the outer frame 1. Turn the second screw 2 clockwise to reduce the inner diameter of the outer frame 1, and vice versa to enlarge the inner diameter of the outer frame 1. After the adjustment, try to move the outer frame 1 to test the tightness of the contact between the cable and the inner wall.

[0055] 3. Adjust the first screw rod 6 so that the cable break is flush with the strip cutter head 4. Turn the first screw rod 6 clockwise to move the swing rod 5 closer to the center of the outer frame 1. Conversely, turn the first screw rod 6 clockwise to move the swing rod 5 closer to the edge of the outer frame 1.

[0056] 4. Adjust the depth of the blade breaking the cable skin, and let the cable skin pass through the arc-shaped protective part 7 and get stuck in the U-shaped cavity; after the adjustment, try to move the cable to test the tightness of the cable and the U-shaped cavity;

[0057] 5. Pull the outer frame 1 to move along the direction of the cable to be stripped. Conversely, the cable moves on the inner wall of the outer frame 1 through the ball 3, allowing the blade to easily strip the cable sheath to complete the cable stripping.

[0058] The electrician wire stripping tool provided in this embodiment is designed with a fixed depth and has an arc-shaped protective portion 7, which can effectively avoid the problem of scratching the wires inside the cable due to inconsistent blade strength, and the stripping speed is fast, which can greatly improve the engineer's stripping efficiency. When the electrician wire stripping tool provided in this embodiment is used to strip the cable, the stripping efficiency is high, it is not easy to hurt the hand, and the wires inside the cable will not be scratched, and the safety and reliability are strong.

[0059] It should be noted that the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0060] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention.
