Description

Technical Field

[0001] This utility model belongs to the field of wire and cable technology, specifically relating to a multi-core wire and cable. Background Technology

[0002] When conducting certain multi-core cable testing experiments, the cable structure under different application scenarios is simulated by changing the position of the internal cores. Then, the mechanical and electrical properties of the cable are measured to verify the rationality of the structural design. At this time, stripping is a necessary step. After stripping, the condition of the cable cores can be visually inspected, such as whether they are damaged, corroded, or broken. This is crucial for evaluating the reliability and safety of the cable.

[0003] Currently, when conducting tests on battery cells, researchers need to repeatedly strip the insulation to change the position of the internal cells in order to obtain different test results. However, because it is impossible to accurately control the depth to which the blade enters the cable, it often damages the intact cells inside the cable. At the same time, the cutting process can result in uneven depths, which seriously affects the cable quality and test results.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a multi-core wire and cable.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figures 1-5As shown, a multi-core cable according to one embodiment of this utility model includes a cable body 1. A pair of slide rails 2 are provided on the outer surface of the cable body 1. A support assembly 3 matching the slide rails 2 is slidably connected to the outer surface of the cable body 1. A cutting assembly 4 matching the support assembly 3 is slidably connected to the upper surface of the support assembly 3. The lower surface of the cutting assembly 4 is attached to the upper part of the cable body 1. When stripping is required for multi-core cable testing, both ends of the cable are first stably fixed to the support assembly 3. Then, the cutting assembly 4 is operated to cut the cable sheath without damaging the internal core. The cutting assembly 4 can accurately adjust the cutting depth and keep this depth uniform, thereby ensuring the stability of the test results.

[0028] Preferred, such as Figure 1 As shown, the support assembly 3 includes two clamping rings 301. A pair of sliders 302 are welded to the inner wall of each clamping ring 301. The outer surfaces of the sliders 302 are slidably connected to the slide rails 2. A support plate 303 is welded to the middle side wall of each clamping ring 301. One inner wall of the support plate 303 is attached to the bottom end face of the cable body 1. By providing a pair of corresponding slide rails 2 on both sides of the outer surface of the cable body 1, when the clamping rings 301 drive the sliders 302 to slide within the slide rails 2, the cable can always maintain a straight, untwisted state, ensuring a straight cut during subsequent stripping and reducing unnecessary damage.

[0029] Furthermore, a pair of fixing blocks are integrally formed on the upper surface of the clamping ring 301. One fixing block is fixedly connected to a bolt 305, and the other fixing block has a threaded hole that matches the bolt 305. There is a gap between the two fixing blocks. That is, part of the end face of the bolt 305 is threaded, the thread of the bolt 305 connects to the threaded hole, and part of the end face of the bolt 305 is a smooth surface. The pair of fixing blocks are respectively provided with a threaded hole and a limiting hole, and the smooth surface of the bolt 305 slides in the limiting hole.

[0030] Before stripping, after adjusting the clamping ring 301 to the appropriate position, rotate the bolt 305 to reduce the gap between the upper pair of fixing blocks, so that the clamping ring 301 clamps and fixes the cable body 1, so that the cable body 1 remains stable during stripping and avoids the cable body 1 from shifting and affecting the stripping quality.

[0031] Furthermore, a support leg 306 is welded to the bottom of each pair of clamping rings 301. During peeling, the bottom end face of the support leg 306 is made to fit against the experimental table, thereby ensuring the stability of the peeling operation.

[0032] like Figures 2-4As shown, a pair of T-slots 304 are formed on the top end face of the support plate 303, and a pair of T-blocks 402 are integrally formed on the bottom end face of the moving ring 401. The outer walls of the pair of T-blocks 402 are slidably connected to the support plate 303 and located on the inner walls of the pair of T-slots 304. A pair of handles 412 are welded to the top end face of the moving ring 401. By manually operating the handles 412, the moving ring 401 is moved to slide on the support plate 303, so that the cutting trajectory is kept at a uniform height during peeling, avoiding the situation of uneven cutting depth.

[0033] like Figures 2-3 As shown, the cutting assembly 4 includes a moving ring 401 and a rotating knob 404. The top end face of the moving ring 401 is provided with a rotating groove that matches the rotating knob 404. The bottom end face of the rotating knob 404 is rotatably connected to the rotating groove. A threaded rod 405 is threadedly connected to the rotating knob 404, and the threaded rod 405 passes through the rotating groove on the moving ring 401.

[0034] A lifting plate 406 is rotatably connected to the bottom end face of the threaded rod 405. A rotating block is welded to the bottom end of the threaded rod 405. A rotating groove matching the rotating block is opened on the lifting plate 406, and the rotating block rotates in the rotating groove.

[0035] A cutting blade 409 is fixedly connected to the bottom end face of the lifting plate 406. By manually rotating the knob 404, the threaded rod 405 is rotated and moved downward, thereby moving the cutting blade 409 downward so that the bottom end of the cutting blade 409 enters the cable body 1.

[0036] Furthermore, the cutting blade 409 is fixedly connected with graduation lines 410, and the shape of the two end sidewalls and bottom of the cutting blade 409 is V-shaped. That is, multiple end faces of the cutting blade 409 are provided with blade edges. The operator can control the depth of the cutting blade 409 into the cable body 1 according to the thickness of the cable sheath and the graduation lines 410 on the cutting blade 409, so as to avoid the cutting depth being too deep or too shallow, which would affect the stripping quality.

[0037] Furthermore, a pair of through slots 407 are provided at both ends of the lifting plate 406, and a placement slot 403 is provided on the top side wall of the moving ring 401. A fixed post 408 is slidably connected to the inner wall of the through slot 407. A pair of opposite end faces of the fixed post 408 are welded to the slot wall of the placement slot 403. A square slot 411 matching the cutting blade 409 is provided on the moving ring 401 in the placement slot 403. The cutting blade 409 passes through and slides in the square slot 411. When the threaded rod 405 rotates, it drives the lifting plate 406 and the cutting blade 409 to move downward. At this time, both ends of the lifting plate 406 are located in the through slot 407 and are attached to the fixed post 408 to move downward. Under the action of the fixed post 408, the cutting blade 409 does not rotate, so that it always remains stable, thereby ensuring the peeling quality.

[0038] When conducting experimental testing on a multi-core cable, it is necessary to change the position of the internal cores to obtain different experimental data. This requires repeatedly stripping the cable's outer sheath. When stripping is required, the operator moves the support assembly 3 along the track of the slide rail 2 to the position on the cable where stripping is needed. Tightening the bolt 305 reduces the opening on the clamping ring 301, clamping and fixing both ends of the cable. Then, rotating the knob 404 moves the threaded rod 405, the lifting plate 406, and the cutting blade 409 downwards, causing the bottom end of the cutting blade 409 to gradually and slowly penetrate the cable. The depth to which the cutting blade 409 penetrates the cable is controlled by the scale line 410. After adjusting to the appropriate depth, the handle 412 is manually pulled to move the moving ring 401 and the T-block 402 to the other side of the cable, so that the cutting component 4 slides smoothly above the support component 3. At this time, the upper sheath of the cable is cut open under the action of the cutting blade 409, thus realizing the stripping of the cable. Then, the staff can change the distribution position of the internal cells of the cable, observe the condition of the internal cells, record experimental data, and after the adjustment and recording are completed, the cable can continue to be tested for the next set of tests after the sheath is repaired.
