Abstract
Description
Technical Field
[0001] This utility model relates to the field of power cable construction and maintenance tools, specifically to an omnidirectional stripping tool for the insulation sheath of power cables. Background Technology
[0002] Currently, stripping the insulation of power cables is a common and crucial process in the installation, repair, and routine maintenance of power engineering projects. However, existing cable stripping tools have many shortcomings and are insufficient to meet the needs of practical work. The following defects exist: 1. Limited Functionality: Most existing cable stripping tools can only perform cutting in one direction, such as circumferential or longitudinal cutting. In actual cable handling work, it is often necessary to cut cables in different directions depending on the cable connection method and construction requirements. For example, when branching cables, it may be necessary to first perform circumferential cutting to determine the stripping location, and then perform longitudinal cutting to accurately remove a specific length of insulation. Using existing single-function tools requires frequent tool changes, which not only increases tool purchase costs but also significantly reduces work efficiency and increases the complexity of operation.
[0003] 2. Limited Applicability: Different models and specifications of power cables have significant differences in outer diameter and insulation thickness. Existing stripping tools often lack sufficient versatility and struggle to adapt to this diversity. Different sized cables may require different sized tools; otherwise, incomplete cutting or damage to the cable core may occur. For example, using an oversized tool to strip a small-diameter cable can easily lead to excessive cutting depth due to poor tool-cable matching, damaging the cable core and affecting its electrical performance and service life. Conversely, using an undersized tool to strip a large-diameter cable may fail to effectively cut the insulation, resulting in difficulties in subsequent connections and compromised construction quality.
[0004] 3. Inaccurate depth control: Controlling the depth of cut is crucial when stripping cable insulation. If the cut is too deep, it can damage the cable core, affecting the cable's electrical performance and lifespan. If the cut is too shallow, the insulation cannot be completely removed, leading to weak cable connections or poor contact. Existing tools often lack precision in depth control, relying mainly on operator experience, which is prone to error and makes it difficult to guarantee consistent and stable stripping quality.

Furthermore, if terms such as "first" or "second" appear in the description of this invention, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0026] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.
[0027] As shown in the attached drawings, this utility model includes a die base 1, a cutting tool 2, and a cable sleeve 3. The die base 1 has a tool mounting groove 4, and the tool 2 can be detachably installed in the tool mounting groove 4. The bottom of the die base 1 is provided with a handle 5, and the two ends of the cable sleeve 3 can be detachably installed on the two side walls of the die base 1.
[0028] The top of the die base 1 is arc-shaped.
[0029] The tool mounting slot 4 has a threaded hole, and the tool 2 has a long slotted hole. The screw passes through the long slotted hole and is screwed into the threaded hole of the tool mounting slot 4 to fix the tool 2.
[0030] The top of the knife 2 is provided with a triangular cutting edge 6, and the two cutting edges of the triangular cutting edge 6 intersect at the top to form a pair of longitudinal cutting edges 7.
[0031] The die base 1 has threaded holes on both sides, and the cable sleeve 3 has elongated holes at both ends. The screw passes through the elongated hole of the cable sleeve 3 and is screwed into the threaded hole on the side of the die base 1 to fix the cable sleeve 3.
[0032] A limit plate 8 is provided on the top of the handle 5.
[0033] The tool mounting slot 4 is an inverted trapezoidal slot.
[0034] The outer wall of handle 5 is provided with anti-slip texture.
[0035] The handle 5 is integrally formed with the die base 1.
[0036] Example 1: First, secure the cable: Insert the power cable whose insulation needs to be stripped into the cable sleeve 3, ensuring that the cable fits tightly against the inner wall of the cable sleeve 3 without any movement. If the cable is long, a clamp or other auxiliary tool can be used to secure one end of the cable to facilitate operation and ensure the stability of the cable during the cutting process.
[0037] The second step is to adjust the depth of cut: Based on the thickness of the cable insulation, loosen the screw on cutter 2 and move cutter 2 to the appropriate depth of cut. Generally, the depth of cut should be slightly less than the thickness of the insulation to prevent damage to the cable core. After adjustment, tighten the screw to fix cutter 2, ensuring that cutter 2 will not move during cutting.
[0038] The third step is to perform the cutting operation: Circumferential cutting: Hold handle 5 and rotate the tool around the cable for one revolution. The blade 2 makes a circumferential cut on the cable insulation using the triangular cutting edge 6. During rotation, keep the tool stable and avoid shaking to ensure a clean circumferential cut, providing a good foundation for subsequent longitudinal cutting or insulation stripping.
[0039] Longitudinal Cutting: After completing the circumferential cut, the tool position can be adjusted as needed to move the cutter 2 along the length of the cable for longitudinal cutting. During longitudinal cutting, the cutting edge 7 is inserted into the cable insulation sheath for cutting. The tool's movement speed and force must be carefully controlled to ensure uniform cutting depth and avoid inconsistent cutting depths. The cable insulation sheath thickness is generally 1-2mm, which can be easily cut through by the cutting edge 7.
[0040] The fourth step is to remove the insulation sheath: After completing the circumferential and longitudinal cuts, the insulation sheath formed by the circumferential and longitudinal cuts can be gently peeled off from the cable.
[0041] Small-diameter cables: When stripping small-diameter cables, select a cable sleeve 3 whose inner diameter matches the cable's outer diameter. After installing the cable sleeve 3 onto the die base 1, because the insulation of small-diameter cables is relatively thin, the cutter depth should be adjusted to a shallower position to prevent damage to the cable core. Perform circumferential and longitudinal cutting operations as described above to complete the stripping of the insulation of the small-diameter cable. During operation, carefully control the force to avoid deformation or damage to the cable due to excessive force.
[0042] Large-diameter cables: For large-diameter cables, select the appropriate size cable sleeve 3 for installation. Since the insulation of large-diameter cables is typically thicker, the cutting depth of the cutter 2 can be appropriately increased, but it must still be ensured that it does not exceed the thickness of the insulation to avoid damaging the cable core. During operation, due to the larger cable diameter, greater force may be required to rotate the tool for circumferential cutting. Operators must maintain a stable grip and operating posture to ensure operational safety.
