Description

Technical Field

[0001] This utility model belongs to the field of power tool technology, specifically relating to a cable taper. Background Technology

[0002] Due to limitations in production technology, site conditions, and transportation, the length of each power cable segment is typically 200–1000 meters. Faults and damage occur in operating cables. Therefore, on-site cable connection and repair are necessary. The common construction method is as follows: first, the semi-conductive layer, insulation layer, and inner semi-conductive layer at the cable ends are removed; then, the conductors are connected. After the conductors are connected, the inner semi-conductive layer, insulation layer, and outer semi-conductive layer are restored using cable accessory fabrication techniques such as wrapping, heat shrinking, cold shrinking, and fusion splicing. In the above construction process, the removal of the cable insulation layer is usually done using a cable taper.

[0003] The prior art CN116598964A discloses a cable taper, which includes a taper assembly, a rotating assembly, and an outer housing. The taper assembly is housed inside the outer housing and is slidably connected to the outer housing via a groove. The rotating assembly passes through the bottom plate of the outer housing and is fixedly connected to the taper assembly. The taper assembly is used to taper the cable in response to the rotation of the rotating assembly after the cable enters the taper assembly from the inlet, thereby increasing the ease of use of tapering the outer insulation layer of the cable and improving work efficiency.

[0004] Existing cable tapers use a uniform national standard diameter. However, due to variations in cable manufacturing processes, conductor and core diameters differ from the national standard, leading to a mismatch between the conductor and the taper diameter. This results in an easily misaligned tapered head, failing to meet welding requirements. Furthermore, existing tapers of a single diameter can only cut one type of cable, making them unsuitable for cables of different diameters. Therefore, it is necessary for those skilled in the art to provide a cable taper to address the problems of the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a cable taper to solve the aforementioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable taper, comprising a housing, wherein the housing is provided with a hollow groove, a support part for supporting the cable is provided on one side of the hollow groove, and a slider is slidably provided on the other side of the hollow groove. A blade is installed on the side of the slider facing the support part, and the blade is provided with a beveled cutting edge; the slider is connected to a driving member, which is used to drive the slider to slide along the hollow groove so that the blade approaches or moves away from the cable supported by the support part.

[0007] As an optional implementation of the above technical solution, both sides of the blade are provided with clamping wheels, and the clamping wheels and the support part cooperate with each other to clamp and fix the cable.

[0008] As an optional implementation of the above technical solution, the support part is provided with two support rollers, and the two support rollers jointly support the cable.

[0009] As an optional embodiment of the above technical solution, the driving component includes a driving screw and a driving handle. One end of the driving screw is threadedly connected to the slider, and the other end of the driving screw passes through the outer shell and is connected to the driving handle.

[0010] As an optional implementation of the above technical solution, the drive screw is provided with a clamping nut.

[0011] As an optional implementation of the above technical solution, the surface of the drive handle is provided with anti-slip texture.

[0012] As an optional embodiment of the above technical solution, the blade is provided with a mounting hole on the side away from the oblique cutting edge, and a bolt is provided in the mounting hole. The bolt passes through the slider and is threadedly connected to the mounting hole.

[0013] As an optional implementation of the above technical solution, the blade is provided with an arc-shaped groove on the side near the oblique cutting edge.

[0014] As an optional implementation of the above technical solution, the outer shell includes an upper shell and a lower shell, which are detachably connected and enclose the hollow groove.

[0015] As an optional embodiment of the above technical solution, the upper housing and the lower housing are connected by a hinge, and a locking screw is provided between the upper housing and the lower housing.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention provides a cable tapering tool. A support portion is provided on one side of a perforated groove, and a slider is slidably mounted on the other side of the groove. A blade is mounted on the side of the slider facing the support portion. The slider is connected to a driving component, which drives the slider to slide along the perforated groove, allowing the blade to approach or move away from the cable supported by the support portion. After the cable is placed on the support portion, the driving component drives the slider to slide along the perforated groove, bringing the blade closer to the cable. Then, rotating the cable or rotating the entire housing relative to the cable causes the beveled blade to cut the cable, thus achieving the cable tapering function. This invention utilizes a support portion to support the cable and a driving component to drive the slider to slide along the perforated groove, bringing the blade closer to the cable and tapering it. Its structure is simple, adaptable to cables of different diameters, and effectively solves the problem of easy eccentricity of the tapered head. Attached Figure Description

[0023] like Figures 1-4 As shown, this embodiment provides a cable taper, including a housing 1. The housing 1 has a hollowed-out groove 2, which is rectangular in structure. A support portion 3 for supporting the cable is provided on one side of the hollowed-out groove 2, and a slider 4 is slidably mounted on the other side of the groove 2. The support portion 3 includes a support platform and is typically located at the bottom of the hollowed-out groove 2. The cable to be cut is placed on the support portion 3. The slider 4 is located at the top of the hollowed-out groove 2 and can slide up and down along the groove 2, thereby moving closer to or away from the support portion 3.

[0024] like Figure 2 As shown, a blade 5 is mounted on the side of the slider 4 facing the support 3, and the blade 5 has a beveled edge. The slider 4 is connected to a driving component, which drives the slider 4 to slide along the slot 2, so that the blade 5 approaches or moves away from the cable supported by the support 3. After the cable is placed on the support 3, the driving component drives the slider 4 to slide along the slot 2, so that the blade 5 approaches the cable. Then, the cable is rotated or the entire outer casing 1 is rotated relative to the cable, so that the beveled edge cuts the cable, thereby realizing the tapering function of the cable.

[0025] This utility model utilizes the support part 3 to support the cable, and drives the slider 4 to slide along the hollow groove 2 through the driving component, so that the blade 5 approaches the cable and tapers the cable. Its structure is simple and can be adapted to cables of different diameters, effectively solving the problem of the tapered head being prone to eccentricity.

[0026] like Figure 2As shown, in one specific embodiment, the blade 5 has clamping rollers 6 on both sides. The clamping rollers 6 and the support part 3 cooperate to clamp and fix the cable. Clamping rollers 6 are provided at each of the four corners of the slider 4, clamping rollers 6 press the cable tightly, facilitating tapering of the cable. Preferably, the support part 3 has two support rollers 7, which together support the cable. Simultaneously, the clamping rollers 6 press the cable tightly, and the cable rotates relative to the outer casing 1, thus achieving the tapering function. This invention utilizes the support rollers 7 and clamping rollers 6 to position the cable, while reducing friction between the support rollers 7 and clamping rollers 6 and the cable, improving operational convenience.

[0027] The driving component includes a driving screw 8 and a driving handle 9. One end of the driving screw 8 is threadedly connected to the slider 4, and the other end of the driving screw 8 passes through the outer shell 1 and is connected to the driving handle 9. The driving screw 8 and the driving handle 9 are fixedly connected. The outer shell 1 has a through hole for the driving screw 8 to pass through, and the slider 4 has a threaded hole adapted to the driving screw 8. The surface of the driving handle 9 has anti-slip texture. By rotating the driving handle 9, the driving screw 8 rotates together with the driving handle 9. Since one end of the driving screw 8 is threadedly connected to the threaded hole of the slider 4, the slider 4 can slide up and down, thereby adjusting the position of the blade 5. Preferably, the driving screw 8 is provided with a clamping nut 10. The clamping nut 10 abuts against the slider 4, improving the sliding stability of the slider 4.

[0028] like Figure 3 and Figure 4 As shown, in one specific embodiment, the blade 5 has a mounting hole 11 on the side away from the oblique cutting edge. A bolt is fitted into the mounting hole 11, and the bolt passes through the slider 4 and is threaded into the mounting hole 11. An arc-shaped groove 12 is provided on the side of the blade 5 near the oblique cutting edge to facilitate cutting the cable.

[0029] like Figure 1 As shown, in this embodiment, the outer casing 1 includes an upper casing 13 and a lower casing 14, which are detachably connected and form the hollow groove 2. The outer casing 1 adopts a split structure of upper casing 13 and lower casing 14, which facilitates opening the upper casing 13 and lower casing 14 and placing the cable between the support roller 7 and the pressure roller 6. This allows for direct tapering of the cable even in the case of a non-disconnected cable, compensating for the eccentricity problem caused by traditional tapering tools due to different cable manufacturing processes, and solving the problem that non-disconnected cables cannot be directly tapered.

[0030] Preferably, the upper housing 13 and the lower housing 14 are connected by a hinge 15, and a locking screw 16 is provided between the upper housing 13 and the lower housing 14. Loosening the locking screw 16 allows the lower housing 14 to be opened, the cable to be placed into the slot 2, the upper and lower housings 14 to be closed, and the locking screw 16 to be tightened. The cable can then be cut using a blade 5. This method is more flexible and convenient, does not require differentiation of cable type, and has a unified operation method.

[0031] In use, for disconnected cables, the cable can be directly inserted between the support roller 7 and the pressure roller 6. For non-disconnected cables, first loosen the locking screw 16, open the lower housing 14, place the non-disconnected cable into the hollow groove 2, then close the upper and lower housings 14 and tighten the locking screw 16. Rotate the drive handle 9 to make the slider 4, carrying the blade 5, gradually approach the cable. When the blade 5 contacts the cable surface, stop rotating the drive handle 9. By rotating the cable or rotating the entire housing 1 around the cable, the oblique cutting edge of the blade 5 cuts the cable, thus achieving the cable tapering function. This invention has a simple structure and is easy to use. It can flexibly taper different types of cables according to construction requirements, improving the convenience of cable tapering and effectively solving the problem of easy eccentricity of the tapered head.
