Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a fast cable shielding layer crimping device. Background Technology

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. In some cable testing and installation, the shielding layer needs to be connected to the test tube, which requires a crimping device.

[0003] A search revealed that the rapid cable shielding layer crimping device (publication number CN200979914Y) includes a cable clamp and an openable cable clamp fixing device. The openable cable clamp fixing device has a first clamping hole, into which the cable clamp is placed. This invention can be applied to cable installation or testing. Its advantages are that by using cable clamps with clamping holes of different diameters, the shielding layers of cables with different outer diameters can be quickly and reliably crimped to the test tube or test device, with convenient disassembly, ensuring the cable testing and installation requirements are met.

[0004] Based on the aforementioned patent, by using cable clamps with second clamping holes of different diameters, the shielding layer of cables with different outer diameters can be quickly and reliably crimped to the test tube or test device. The cable clamps are easy to install and remove, ensuring the cable test installation requirements. However, when workers use the handheld device for crimping, slippage may occur between the cable and the shielding layer, causing the crimping position to shift and the crimped cable to not meet the requirements. In response to this technical problem, this application proposes a rapid cable shielding layer crimping device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid cable shielding layer crimping device. By rotating the rotating sleeve, the clamping plate can clamp and fix the cable. At the same time, the limiting plate on the clamping block, together with the elastic force of the second spring, can limit the shielding layer placed on the cable surface, thereby ensuring that neither the cable nor the shielding layer will be displaced during crimping, thus improving product quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fast cable shielding layer crimping device includes a fixed cylinder, a second crimping block fixedly connected to the left end of the fixed cylinder, a first crimping block connected to the rear end of the second crimping block via a rotating component, a first spring fixedly connected to the inner wall of both the first and second crimping blocks, a clamping block fixedly connected to the other end of each first spring, a second spring fixedly connected to the inner wall of both the left and right ends of the clamping block, a slider fixedly connected to the other end of each second spring, a limit plate fixedly connected to the outward end of each slider, a guide assembly provided on the inner wall of the fixed cylinder, and a clamping plate connected to the top end of the fixed cylinder via a driving assembly.

[0008] Furthermore, the rotating component includes two L-shaped blocks I fixedly connected to the rear end of the second pressing block. A rotating rod is fixedly connected to the inner wall of the L-shaped block I, and an L-shaped block II is rotatably connected to the outer wall of the rotating rod.

[0009] Furthermore, the front end of the L-shaped block two is fixedly connected to the rear end of the first pressing block, and the front ends of both the first pressing block and the second pressing block are fixedly connected to a connecting rod one, and the front ends of the connecting rod one are fixedly connected to a handle.

[0010] Furthermore, the outer walls of the clamping blocks are slidably connected to the inner walls of the first pressing block and the second pressing block, and the outer walls of the sliders are slidably connected to the inner walls of the clamping blocks.

[0011] Furthermore, the guide assembly includes a plurality of spring cylinders fixedly connected around the inner wall of the fixed cylinder, and a guide plate is fixedly connected to the driving ends of two adjacent spring cylinders.

[0012] Furthermore, the drive assembly includes two fixed blocks fixedly connected to the top of the fixed cylinder. A bidirectional threaded rod is rotatably connected to the inner wall of the fixed block. A rotating sleeve is fixedly connected to the middle of the outer wall of the bidirectional threaded rod. Connecting blocks are threaded to both the front and rear sides of the outer wall of the bidirectional threaded rod. A connecting rod II is fixedly connected to one end of each connecting block.

[0013] Furthermore, the inner end of each of the two connecting rods is fixedly connected to the outer end of the clamping plate, and the outer wall of each of the two connecting rods is slidably connected to the inner wall of the fixed cylinder.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, rotating the rotating sleeve can drive the clamping plate to clamp and fix the cable. At the same time, the limiting plate on the clamping block, together with the elastic force of the second spring, can limit the shielding layer placed on the surface of the cable, thereby ensuring that neither the cable nor the shielding layer will be displaced during crimping, which can improve product quality.

[0016] 2. In this utility model, the cable can be positioned on the central axis of the fixed cylinder under the reaction force of the spring cylinder, ensuring the accurate position of the cable during crimping. At the same time, the limiting plate can move under the action of the shielding layer deformation during the crimping process, without affecting the crimping of the shielding layer.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-4This utility model provides an embodiment of a rapid cable shielding layer crimping device, comprising a fixed cylinder 1, a second crimping block 3 fixedly connected to the left end of the fixed cylinder 1, a first crimping block 2 connected to the rear end of the second crimping block 3 via a rotating component, the rotating component comprising two L-shaped blocks 12 fixedly connected to the rear end of the second crimping block 3, a rotating rod 13 fixedly connected to the inner wall of the L-shaped blocks 12, and an L-shaped block 18 rotatably connected to the outer wall of the rotating rod 13, the front end of the L-shaped block 18 fixedly connected to the rear end of the first crimping block 2, and the front ends of both the first crimping block 2 and the second crimping block 3 being fixed. A connecting rod 6 is connected, and a handle 7 is fixedly connected to the front end of the connecting rod 6. A first spring 19 is fixedly connected to the inner wall of the first pressing block 2 and the second pressing block 3. A clamping block 4 is fixedly connected to the other end of the first spring 19. A second spring 20 is fixedly connected to the inner wall of both the left and right ends of the clamping block 4. A slider 21 is fixedly connected to the other end of the second spring 20. The outer wall of the clamping block 4 is slidably connected to the inner wall of the first pressing block 2 and the second pressing block 3. The outer wall of the slider 21 is slidably connected to the inner wall of the clamping block 4. A limit plate 5 is fixedly connected to the outward end of the slider 21.

[0025] Specifically, by pulling the handle on the first crimping block 2 in conjunction with the connecting piece, the opening and closing of the first crimping block 2 can be controlled, and the clamping block 4 will crimp the cable. The limiting plate 5 on the clamping block 4, together with the elastic force of the second spring 20, can limit the shielding layer placed on the surface of the cable, ensuring that it will not move when crimping is prepared. At the same time, during the crimping process, the limiting plate 5 can move under the action of the deformation of the shielding layer, without affecting the crimping of the shielding layer. After the cable is removed after crimping, it will reset under the action of the elastic force of the second spring 20.

[0026] A guide assembly is provided on the inner wall of the fixed cylinder 1. The guide assembly includes multiple spring cylinders 14 fixedly connected around the inner wall of the fixed cylinder 1. A guide plate 15 is fixedly connected to the driving end of two adjacent spring cylinders 14. A clamping plate 17 is connected to the top of the fixed cylinder 1 through the drive assembly. The drive assembly includes two fixed blocks 10 fixedly connected to the top of the fixed cylinder 1. A bidirectional threaded rod 9 is rotatably connected to the inner wall of the fixed block 10. A rotating sleeve 11 is fixedly connected to the middle of the outer wall of the bidirectional threaded rod 9. Connecting blocks 8 are threadedly connected to both the front and rear sides of the outer wall of the bidirectional threaded rod 9. A connecting rod 16 is fixedly connected to the inner end of each connecting block 8. The inner end of each connecting rod 16 is fixedly connected to the outer end of the clamping plate 17. The outer wall of each connecting rod 16 is slidably connected to the inner wall of the fixed cylinder 1.

[0027] Specifically, after inserting the cable into the fixed cylinder 1, it will be clamped into the four guide plates 15, and the guide plates 15 will be pushed to compress the spring cylinder 14. The cable will be positioned on the central axis of the fixed cylinder 1 under the reaction force of the spring cylinder 14, ensuring the accurate position of the cable during crimping. Rotating the rotating sleeve 11 can drive the clamping plate 17 to clamp and fix the cable, so that the cable and the shielding layer will not move during crimping, which can improve product quality. The fixed cylinder 1 is rectangular in shape. When conditions permit, the device can be placed on a platform, so that the operator can hold the upper handle 7 and press down to crimp, which is more labor-saving than holding it by hand.

[0028] Working principle: The shielding layer to be crimped is placed on the outer wall of one end of the cable. The first crimping block 2 is opened and the cable is inserted into the fixed cylinder 1 until the shielding layer is between the two limiting plates 5 on the clamping block 4. This pushes the guide plate 15 to squeeze the spring cylinder 14, thereby correcting the position of the cable under the action of the spring cylinder 14, ensuring that the cable is on the central axis of the fixed cylinder 1. Then, the rotating sleeve 11 is rotated to drive the connecting block 8 to move relative to the bidirectional threaded rod 9, so that the fixed block 10 pushes the clamping plate 17 close to both sides of the cable to clamp and fix the cable. Then, the handle 7 is pulled down to drive the first crimping block 2 to rotate, so that the clamping block 4 on the first crimping block 2 comes into contact with the shielding layer for crimping. During crimping, the shielding layer will deform, pushing the limiting plate 5 to move and stretching the second spring 20. After crimping is completed, the rotating sleeve 11 is rotated in the opposite direction to release the limitation on the cable. Then the first crimping block 2 can be opened to pull out the cable. The limiting plate 5 will also return to its original position under the action of the second spring 20, limiting the shielding layer of the next cable to be crimped.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
