Description

Technical Field

[0001] This utility model relates to the technical field of wire stripping devices; specifically, this utility model relates to a wire stripping device for signal cables. Background Technology

[0002] Signal cables are common electronic components used in electrical circuits. Their primary function is to provide electrical connections and signal transmission between devices and components, components and cabinets, and systems and subsystems, while preventing signal distortion and energy loss between systems. When installing signal cables, a certain length of the outer insulation layer needs to be stripped from the cable ends before wiring.

[0003] When wiring signal cables, a certain length of the outer insulation layer needs to be stripped from the wire ends. This is usually done manually by using a blade to cut open the outer insulation and then severing it. This is not only cumbersome, but also prone to causing cuts during the stripping process. Furthermore, it is difficult to effectively control the length of the stripped wire ends. Therefore, we propose a signal cable stripping device. Utility Model Content

Detailed Implementation

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. 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 are within the protection scope of this utility model.

[0027] like Figures 1 to 4 As shown, this utility model provides a signal cable stripping device, comprising:

[0028] Base 1 has an "h" shaped structure;

[0029] The first rotating ring 2 has a through hole 3 on the base 1. The rotating ring is rotatably installed in the through hole 3. The center of the rotating ring has a channel 4 through which wires can pass.

[0030] Two first blades 5 are mounted on the first rotating ring 2 and located on the rear side of the first rotating ring 2. The two first blades 5 are distributed opposite each other on both sides of the channel 4. The first blades 5 are arranged to be parallel to the axial direction of the channel 4, and the first blades 5 can be displaced radially along the first rotating ring 2.

[0031] The second rotating ring 6 is located behind the first rotating ring 2 and is coaxial with the first rotating ring 2;

[0032] Two second blades 7 are mounted on the first rotating ring 2 and located inside the first rotating ring 2. The two first blades 5 are distributed opposite each other. The line connecting the two first blades 5 is parallel to the line connecting the two second blades 7. The second blades 7 are configured to be perpendicular to the circumference of the channel 4 and are configured to be able to be displaced radially along the second rotating ring 6.

[0033] The slide bar 8 has one end fixed to the first blade 5 and the other end passing through the second blade 7, connecting the first blade 5 and the second blade 7 located on the same side.

[0034] In this embodiment, the first blade 5 is used to cut the wire sheath along its length, and the second blade 7 is used to cut the wire sheath circumferentially. The first blade 5 and the second blade 7 are connected by a slide bar 8, and the second blade 7 can slide on the slide bar 8, allowing adjustment of the distance between the first blade 5 and the second blade 7 to accommodate different wire stripping requirements.

[0035] The first blade 5 is configured such that its rear end is inclined outward relative to its front end, and the difference in distance between the front and rear ends of the first blade 5 and the center of the first rotating ring 2 is not less than the maximum depth of the wire sheath. This configuration ensures that when the first blade 5 cuts into the wire sheath, its blades cut in succession from front to back, with the rear ends of its blades located outside the wire, resulting in smoother cutting along the length of the wire sheath.

[0036] The second blade 7 is fitted with a first clamping plate 9 on its outer side. A guide rod 10 is fixed to the rear side of the first clamping plate 9. The outer end of the guide rod 10 passes through the second blade 7. A first spring 11 is provided on the outside of the guide rod 10, with its two ends respectively connecting the second blade 7 and the first clamping plate 9. A clamping bolt 12 is rotatably connected to the outer end of the first blade 5. The clamping bolt 12 is threaded through the second rotating ring 6.

[0037] In use, when the clamping bolt 12 is rotated, the second blade 7 is moved inward. The second blade 7 pushes the first clamping plate 9 inward through the first spring 11, and the first clamping plate 9 clamps the wire. If the clamping bolt 12 is rotated again, the first spring 11 will be compressed, and the second blade 7 will cut into the wire sheath to a specified depth.

[0038] Then, rotate the wire so that its sheath is cut in a circumferential direction.

[0039] Reverse the clamping bolt 12 to remove the second blade 7 from the wire and place the front end of the wire into the area between the two first blades 5. Then, rotate the clamping bolt 12 again to re-insert the second blade 7 into the area where the wire sheath was circumferentially cut. During this process, the second blade 7 drives the first blade 5 to move inward synchronously through the guide rod 10, so that the first blade 5 also cuts into the wire sheath to the same depth.

[0040] Then, the second rotating ring 6 is pushed directly towards the first rotating ring 2. During this process, the second blade 7 and the first clamping plate 9 will cause the wire to move forward, the front end of the wire passes through the channel 4, and the wire sheath is cut by the first blade 5. In this way, both the length and circumferential directions of the wire sheath can be cut.

[0041] In this embodiment, an inner ring 13 is provided inside the first rotating ring 2. The inner cavity of the inner ring 13 is a channel 4. The two sides of the inner ring 13 are connected to the first rotating ring 2 via guide rails 14. The first blade 5 is slidably mounted on the guide rails 14. The guide rails 14 connect the inner ring 13 to the first rotating ring 2. When the wire is pushed forward, the wire passes through the inside of the inner ring 13. The guide rails 14 slidably mount the first blade 5 on the first rotating ring 2.

[0042] Furthermore, two opposing arc-shaped support plates 15 are fixedly disposed on the inner wall surface of the inner ring 13. The front end of the arc-shaped support plate 15 is flush with the front end face of the inner ring 13, and the rear end of the arc-shaped support plate 15 extends out of the inner ring 13. The line connecting the two arc-shaped support plates 15 is perpendicular to the line connecting the two first blades 5. When the front end of the wire is placed between the two first blades 5, the arc-shaped support plate 15 can support the front end of the wire to stabilize the position of the front end of the wire, so that the two first blades 5 can cut into the wire sheath more effectively.

[0043] Both sides of the inner wall of the through hole 3 are threaded with lead screws 16. The lead screws 16 are perpendicular to the line connecting the two first blades 5. The opposite ends of the two lead screws 16 are slidably fitted with second clamping plates 17, and a second spring 18 is provided between the second clamping plates 17 and the lead screws 16.

[0044] By rotating the lead screw 16, when the lead screw 16 moves inward, it can drive the second clamping plate 17 to move inward through the second spring 18, and the second clamping plate 17 can clamp the wire.

[0045] Based on this, a slide plate 19 is slidably mounted on the guide rail 14, the front end of the guide rod 10 is fixedly connected to the slide plate 19, and the front side of the outer end of the first blade 5 is rotatably engaged with the slide plate 19, so that the first blade 5 can rotate and its blade can be disengaged from the wire sheath. The middle of the second blade 7 and the first clamping plate 9 are both provided with through slots 20 that allow the first blade 5 to pass through and rotate.

[0046] After the wire sheath is cut along its length, the first blade 5 can be rotated out of the wire sheath, and then the wire can be clamped and fixed by rotating the lead screw 16 using the second clamping plate 17. At this time, since the distance between the clamping area of ​​the second clamping plate 17 and the area where the second blade 7 cuts into the wire sheath is very small, the wire will not twist when the second rotating ring 6 is directly rotated to make circumferential cuts using the second blade 7, ensuring that the wire sheath can be effectively cut circumferentially.

[0047] Furthermore, a push rod 21 is fixedly connected to the front end of the outer side of the first blade 5. The push rod 21 is rotatably engaged with the slide plate 19. The slide plate 19 is provided with a groove 22 for the push rod 21 to enter when it rotates. The rear end of the push rod 21 is inclined outward so that it can drive the first blade 5 to rotate when it is squeezed by the second blade 7.

[0048] By setting the push rod 21 and the groove 22, when the second rotating ring 6 is pushed forward to the foremost position, the first blade 5 enters the through groove 20, and the second blade 7 causes the first blade 5 to rotate outward and detach from the wire sheath by pressing the push rod 21, so as to realize the automatic detachment of the first blade 5 from the wire. During this process, the push rod 21 enters the groove 22.

[0049] When using:

[0050] First, pass the front end of the wire through the first clamping plate 9 and place it on the arc-shaped support plate 15. Then, push the second arc-shaped plate back and forth to adjust the position of the second blade 7 according to the required length of the outer sheath to be cut.

[0051] 2. Rotate the clamping bolt 12, and the second blade 7 and the first blade 5 will move inward and cut into the skin to the same depth. At this time, the tip of the first blade 5 will cut into the front end of the wire skin.

[0052] 3. Push the second rotating ring 6 forward, and the second blade 7, together with the first clamping plate 9, pushes the wire through the channel 4 and begins to cut the wire sheath in the length direction.

[0053] During this process, the push rod 21 is squeezed by the second blade 7 and drives the first blade 5 to rotate, so that the blade of the first blade 5 automatically detaches from the wire sheath, while the second blade 7 remains in the state of cutting into the wire sheath.

[0054] Fourth, rotate the lead screw 16 so that the second clamping plate 17 clamps and fixes the wire.

[0055] 5. Rotate the second rotating ring 6 so that the second blade 7 makes circumferential cuts on the wire sheath, thereby realizing the wire stripping operation for signal wire construction.

[0056] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
