Description

Technical Field

[0001] This utility model relates to the field of electrical installation equipment technology, specifically a cable stripping device. Background Technology

[0002] In electrical engineering, communications engineering, and many industrial fields, cables serve as the primary carriers of signal transmission and power supply, making their installation and wiring crucial. Especially during cable termination, repair, or replacement, it is often necessary to strip the cable ends—removing a certain length of the outer sheath to expose the internal conductors for connection. This process requires ensuring both efficient stripping and preventing damage to the conductors, resulting in clean, smooth cuts to meet the needs of subsequent wiring.

[0003] The shortcomings of existing technology:

[0004] Currently, cable stripping is traditionally performed using tools such as wire strippers or hand pliers. These tools are generally sufficient for stripping small-diameter or single-core cables, as the sheath is peeled off by clamping and rotating the cable and using the cutting edge of the jaws. However, when dealing with larger-diameter cables or multi-core wires, traditional wire strippers and hand pliers become inadequate. Due to design limitations, these tools are often unsuitable for stripping large-diameter cables, making manual stripping with blades a necessary but unfortunate option. However, the uncontrollable nature of blade stripping often results in uneven cuts, poor aesthetics and consistency, and this manual operation is not only inefficient and time-consuming but also poses certain safety hazards. Therefore, this traditional stripping method is no longer sufficient to meet the actual needs of current cable installation work. Utility Model Content

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integrated connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified. Example

[0031] Please see Figure 1-5 As shown, this utility model provides a technical solution for a cable stripping device: A cable stripping device includes a mounting collar 1, with symmetrically arranged telescopic grooves 2 on the upper and lower sides of the mounting collar 1. A circumferential cutting component 3 for cutting the cable sheath is movably installed in the telescopic grooves 2. Positioning components 4 are interactively installed at both ends of the mounting collar 1 for positioning the device on the cable. The circumferential cutting component 3 includes a telescopic block 301 and a through groove 303. The telescopic block 301 is movably installed in the telescopic groove 2 and slides up and down within the telescopic groove 2. A return spring 302 is symmetrically installed on one side of the telescopic block 301 and between the telescopic groove 2. The through groove 303 is symmetrically opened in the center on the mounting collar 1, located inside the telescopic groove 2. A circumferential cutting blade 304 is fixedly installed on the inner wall of the telescopic block 301 for cutting the cable sheath, and the end of the circumferential cutting blade 304 is located in the through groove 303.

[0032] Once the positioning component 4 positions the device at the end of the cable, the user can begin cutting and stripping. During cutting, the user stabilizes the cable with one hand and holds the telescopic blocks 301 at both ends of the telescopic groove 2 with the other. The telescopic blocks 301 overcome the spring force of the return spring 302, propelling the circumferential cutting blade 304 towards the cable sheath. Then, the user rotates the mounting collar 1 and the telescopic blocks 301 with wrist force. Through the rotation of the telescopic blocks 301, the circumferential cutting blade 304 achieves a circumferential cut on the cable sheath. Because the cable sheath has a certain thickness and is relatively hard, the user can perform multiple circumferential cuts as needed until a metallic feel or a metallic friction sound is heard, indicating that the cable sheath has been cut through. At this point, the user releases their hand, and the return spring 302 causes the circumferential cutting blade 304 to separate from the cable. Then, the positioning component 4 is opened to remove the device, and the cut cable sheath is removed from the end.

[0033] The ring-cutting assembly 3 and the ring-cutting blade 304 enable rapid ring cutting along the section of the cable sheath to be cut. The operation is simple and efficient, the cut is smooth and clean, and it does not hurt hands. It significantly improves the aesthetics of the cable end, the stripping efficiency, and the safety during the stripping process. Furthermore, the telescopic block 301 drives the ring-cutting blade 304 to extend and retract, making the device compatible with cables of various diameters and highly adaptable. At the same time, the user can adjust the ring-cutting position according to the actual stripping length required, which is more flexible and better meets the actual needs of current cable construction operations.

[0034] The positioning assembly 4 includes a positioning ring 401, an adjusting screw 403, and a pressure bar 404. The positioning ring 401 is rotatably connected to both ends of the mounting sleeve 1 via a groove, and they are symmetrical to each other. A mounting groove 402 is formed through one side of the positioning ring 401. The adjusting screw 403 is rotatably connected to the positioning ring 401 on one side of the mounting groove 402. The threads of the adjusting screw 403 are symmetrical, and one end of the adjusting screw 403 has an internal hexagonal hole for rotational adjustment. The pressure bar 404 is symmetrically and movably mounted on both ends of the adjusting screw 403 and threadedly connected to it. A symmetrical arc-shaped groove is formed on the end face of the pressure bar 404 on the adjacent side. A clamping bolt 405 is connected to the end of the pressure bar 404 away from the adjusting screw 403. One end of the clamping bolt 405 also has an internal hexagonal hole for rotational adjustment. One end of the clamping bolt 405 is slidably connected to one side of the pressure bar 404, and the other end is threadedly connected to the other side of the pressure bar 404. Because the threads of the adjusting screw 403 are symmetrical, the adjusting screw 403 can only drive the two pressure bars 404 to move in opposite directions or in the opposite direction.

[0035] When positioning the device on a cable, first remove the clamping bolt 405. Then, rotate the adjusting screw 403 to separate the two clamping strips 404 until the distance between the two clamping strips 404 is greater than the diameter of the cable. Stop rotating the adjusting screw 403, and the user can then slip the device onto the cable. The cable lies between the arc-shaped grooves of the two clamping strips 404. Next, rotate the adjusting screw 403 in the opposite direction until the arc-shaped groove on the inner side of the clamping strip 404 fits tightly against the outside of the cable sheath. Then, reinstall the clamping bolt 405 at the end of the clamping strip 404 and tighten it, ensuring the clamping strip 404 is tightly pressed against the cable sheath. At this point, the device is positioned on the cable. When removing the device after cutting, first remove the clamping bolt 405, then rotate the adjusting screw 403 in the opposite direction to separate the clamping strip 404 from the cable.

[0036] The positioning component 4 enables the device to be quickly and flexibly positioned at the end of the cable, ensuring the stability of the device and the accuracy of the cut position during the circumferential stripping process. Furthermore, during the positioning process, the upper and lower pressure bars 404 move synchronously towards the center, ensuring that the axis of the cable is collinear with the axis of the device during the circumferential stripping process, further improving the circumferential stripping effect.

[0037] The positioning ring 401 has limit grooves 406 extending through both sides of the mounting groove 402. The side wall of the pressure strip 404 away from the adjusting screw 403 is slidably connected to the limit groove 406 by a slider. As the pressure strip 404 moves up and down along the mounting groove 402, the limit groove 406 can improve the stability of the pressure strip 404 and prevent displacement and jamming.

[0038] The telescopic block 301 has a groove on one side outside the mounting collar 1 for easy gripping, which can improve the stability and comfort of gripping.

[0039] The telescopic block 301 has limiting plates 3011 on both sides that match the inner wall of the telescopic groove 2. The limiting plates 3011 limit the lifting height of the telescopic block 301 to prevent the telescopic block 301 from separating from the telescopic groove 2, which may prevent it from entering the telescopic groove 2 smoothly when gripping later.

[0040] A tapered strip 4041 is provided in the arc-shaped groove on the inner side of the pressure strip 404 to increase the friction. The tapered strip 4041 can increase the friction and improve the clamping effect of the pressure strip 404 on the cable.

[0041] The working principle of this utility model is as follows:

[0042] When the cable sheath needs to be cut and stripped, first remove the clamping bolt 405. Rotate the adjusting screw 403 to separate the two clamping strips 404 until the distance between the two clamping strips 404 is greater than the cable diameter. At this point, stop rotating the adjusting screw 403. The user can then place the installation collar 1 at the designated cutting position at the cable end according to the stripping length. Next, rotate the adjusting screw 403 in the opposite direction until the arc-shaped groove on the inner side of the clamping strip 404 fits tightly against the outside of the cable sheath. Then, reinstall the clamping bolt 405 at the end of the clamping strip 404 and tighten it, ensuring that the two clamping strips 404 are tightly pressed against the cable sheath for positioning. At this point, circumferential cutting and stripping can be performed. The user stabilizes the cable with one hand and holds the telescopic blocks 301 at both ends of the telescopic groove 2 with the other. The telescopic blocks 301 overcome the elastic force of the return spring 302, pushing the circumferential cutting blade 304 towards the cable sheath. Then, the user rotates the mounting collar 1 and the telescopic blocks 301 with wrist force. Through the rotation of the telescopic blocks 301, the circumferential cutting blade 304 achieves circumferential cutting of the cable sheath. The cutting continues until a metallic feel or a metallic friction sound is heard, indicating that the cable sheath has been cut through. At this point, the user releases their hand, and the return spring 302 causes the circumferential cutting blade 304 to separate from the cable. Then, the clamping bolt 405 is removed, and the adjusting screw 403 is rotated in the opposite direction to separate the clamping strip 404 from the cable, allowing the device to be removed. Finally, the cut cable sheath can be removed from the end.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.

The scope of protection of this utility model is defined by the appended claims and their equivalents.
