Description

Technical Field

[0001] The invention relates to the technical field of cable production, in particular to a docking device for cable production. Background Art

[0002] Cables are usually made of several or several groups of wires twisted together like ropes. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. Cables have the characteristics of being energized inside and insulated outside. When producing cables, the metal wires need to be stretched and twisted into a core. After the core is bundled, an insulating layer is wrapped on the outside by extrusion, etc., and then the required armor and external protective layer are wrapped in turn. Finally, the required cable is combined and rolled up for easy transportation.

[0003] During the cable production process, various tests and tests are involved to ensure the quality and performance of the product. Cable docking is a key link in the installation and use of cables, and requires rigorous testing both during production and after installation. During the production stage, the main tests may focus on the quality control of raw materials and manufacturing processes, such as the electrical properties of insulating materials, the mechanical strength of sheath materials, etc. In addition, the reliability of cable connections is also subject to a variety of tests, such as conductor resistance test, insulation resistance test, withstand voltage test, leakage current test, and mechanical tension test.

[0004] The commonly used cable docking devices can generally fix the inserted cables at both ends of the device to prevent the cables from being pulled out by external forces.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 7 In the embodiment of the present invention, it includes a box body 1 and a cable 2; sealing joints 13 are respectively installed at both ends of the box body 1, and the cable 2 is inserted into the box body 1 through the sealing joints 13; a cutting structure 7 is installed in the middle of the box body 1, and the cutting structure 7 includes a cutting groove 71, a pull rod 74 is slidably installed in the cutting groove 71, a mounting block 73 is installed at one end of the pull rod 74, and a cutting blade 72 is installed on the mounting block 73; a groove 6 is arranged on the cutting groove 71, and a long groove 712 is opened on a side of the cutting groove 71 connected to the groove 6, and the cutting blade 72 passes through the long groove 712 and enters the groove 6; the two ends of the groove 6 point to the sealing joints 13 located at the two ends of the box body 1 respectively; a cover plate 64 is arranged on the groove 6, and a primary pressing block 65 inserted into the groove 6 is installed on the cover plate 64;

[0032] The box body 1 is provided with mounting seats 5 located on both sides of the groove 6, and the mounting seats 5 are provided with multiple groups of copper busbars 51;

[0033] The mounting seat 5 is provided with a wire fixing structure 4 located at both ends of the wiring copper bar 51, and the wire fixing structure 4 is used to position each wire core 21 of the cable 2 respectively;

[0034] Stripping structures 3 are respectively installed on the side surfaces of both ends of the box body 1 , and the stripping structures 3 are used to strip the insulation layer of the wire core 21 .

[0035] The box body 1 of the device is used for docking the cable 2. The device can be directly applied to the newly processed cable 2. It is not necessary to first strip the cable 2 and install the wiring terminal. The cable 2 can be directly inserted into the sealing joints 13 at both ends of the box body 1 and fixed. Then the inserted cable 2 is pressed into the groove 6 and fully compressed with the cover plate 64 and the first-level pressing block 65. The cable 2 is located on the surface of the long groove 712. The pull rod 74 is pulled, and the cutting blade 72 slides from the bottom along the axis of the cable 2 and cuts the outer coating of the cable 2, so that the internal core 21 can be stripped out for corresponding connection of each core 21.

[0036] For the cable 2 with a separate coating layer on the core 21, the device is also provided with a stripping structure 3. The core 21 is placed in a designated position of the stripping structure 3 to cut off the outer coating layer, and the core 21 is directly pulled out to obtain a bare wire. After stripping, the core 21 is passed through the wire fixing structure 4 and clamped, and the wire is installed on the wiring copper bus 51, and the entire cable 2 docking work is completed.

[0037] The device is suitable for the cable 2 docking work of a monitoring nature during the cable 2 production process. There is no need to perform complex processing such as stripping and installing wiring terminals on the processed cable 2. The device can be used directly to easily and conveniently complete the quick stripping and wiring work, reducing complex equipment configuration and tedious installation workload, significantly improving the operational efficiency of cable 2 docking, and can fully meet the use requirements of docking various types of cables 2 during the cable 2 production process.

[0038] As another embodiment of the present invention, please refer to Figure 1 and Figure 4 , the two ends of the copper busbar 51 are respectively provided with wiring terminals 52, and the wire core 21 passes through the fixed wire structure 4 to connect the corresponding wiring terminals 52. The wiring terminals 52 are used to fix the exposed wires to the copper busbar 51. The wiring terminals 52 in the accompanying drawings are only used as a display of available wiring terminals 52 and should not be regarded as a restrictive structure. According to the requirements of different types of cable 2 conductors, various types of wiring terminals 52 can be selected for installation, all of which meet the structural requirements of the device.

[0039] See also Figure 2 , Figure 3 and Figure 5Both ends of the cutting groove 71 are provided with a slope section 711, one end of the pull rod 74 passes through the box body 1 and is connected to a cross bar 75, and blocks 751 are installed on both sides of the cross bar 75. A limit block 14 made of elastic material is installed on the outside of the box body 1, and the shape of the limit block 14 matches the shape of the block 751. The cross bar 75 is used to pull the pull rod 74, and the block 751 cooperates with the limit block 14 to prevent sliding after the cutting blade 72 is retracted. The slope section 711 is used to cooperate with the cutting blade 72. Since the upwardly protruding cutting blade 72 is used in the present device to cut the coating of the cable 2 pressed down from above, after the cable 2 is cut and connected, the cutting blade 72 will be exposed upward, which may easily cause scratches to the operator or cause the wire core 21 to be cut during use. Therefore, downward slopes are set at both ends of the cutting groove 71. When the mounting block 73 moves to one end, it is suspended below, and the cutting blade 72 sinks downward along the slope section 711 into the interior of the cutting groove 71 to avoid risks of use.

[0040] See also Figure 2 , Figure 3 and Figure 5 The mounting block 73 is provided with a through slot 731, and a connecting block 76 passing through the through slot 731 is installed on the mounting block 73. The connecting block 76 is slidably connected to the mounting block 73, and the cutting blade 72 is vertically installed on the connecting block 76. The through slot 731 is used to cooperate with the installation of the connecting block 76. The connecting block 76 is along the cutting slot 71, and the cutting slot 71 is raised and lowered. In the middle area of ​​the cutting slot 71, the connecting block 76 is raised, and the cutting blade 72 protrudes upward. In the slope section 711, the connecting block 76 is pushed down, and the cutting blade 72 sinks to avoid accidental injury.

[0041] See also Figures 1 to 4 , vertical baffles 63 are arranged on both sides of the groove 6, a clamping plate 61 is arranged inside the baffle 63, and multiple groups of springs 62 are installed between the baffle 63 and the clamping plate 61. The baffles 63 are located on both sides to provide support for the springs 62, and the clamping plate 61 pushes the cable 2 to the middle position when the springs 62 are pressed. For cables 2 of different diameters, it can ensure that the cable 2 is in the middle of the groove 6, and increase the resistance of the cable 2, so that the cutting blade 72 can fully contact the cable 2 and cut the coating layer.

[0042] See also Figure 1 , Figure 2 and Figure 6The wire fixing structure 4 includes a wire fixing seat 41 installed on the mounting seat 5. The wire fixing seat 41 is provided with a plurality of U-shaped wire fixing grooves 411. The wire core 21 passes through the wire fixing grooves 411. Both sides of the wire fixing grooves 411 are provided with elastic springs 412 protruding inward. The wire fixing structure 4 is used to limit each separated wire core 21 individually, so that the wire cores 21 are arranged more neatly. The wire cores 21 are embedded in the wire fixing grooves 411. The elastic springs 412 on both sides exert a certain squeezing effect on the wire cores 21 to reinforce the wire cores 21.

[0043] See also Figure 6 , a pressure plate 42 is provided on the fixed wire seat 41, and a plurality of secondary pressure blocks 421 inserted into the fixed wire groove 411 are installed on the pressure plate 42, and the two ends of the pressure plate 42 are connected to the fixed wire seat 41 by bolts 43. The pressure plate 42 presses each secondary pressure block 421 on the surface of the wire core 21 to fix the wire core 21. The bolts 43 are used to fix the pressure plate 42 on the fixed wire seat 41. The pressure plate 42 is a liftable structure that can act on wire cores 21 of various diameters. It should be noted that the fixed wire structure 4 in the present device is only used to standardize the installation position of each wire core 21, and it is not necessary to provide a completely fixed effect on the wire core 21. The reinforcement of the cable 2 is mainly performed by the sealing joint 13, so it is not necessary to have the effect of cleaning and reinforcing each wire core 21. And the sealing structure is a very common and widely used universal accessory in this field, so the present device does not impose too many restrictions on the specific structure of the sealing structure.

[0044] See also Figure 1 and Figure 7 The stripping structure 3 includes a fixing plate 31 vertically installed in the box body 1, and a primary groove 311 is provided on the fixing plate 31. A cutting plate 32 is hinged on the fixing plate 31, and a secondary groove 321 is provided on the cutting plate 32. Relative stripping pliers 33 are respectively installed in the primary groove 311 and the secondary groove 321, and the stripping pliers 33 are provided with a plurality of jaws 331 of different sizes. The stripping structure 3 is used to remove a small section of the insulation layer from the wire core 21, so there is no need to cut and strip the axial line. The stripping pliers 33 are only used to clamp at the length position where stripping is required. After cutting the insulation layer, the wire core 21 is pulled outward to obtain a bare wire of sufficient length. The jaws 331 on the stripping pliers 33 are used to meet the needs of stripping wire cores 21 of different diameters.

[0045] See also Figure 1The box body 1 is provided with a box cover 11, and the box body 1 and the box cover 11 are provided with locks 12 that cooperate with each other. The locks 12 can seal the box body 1 and the box cover 11 to protect the internal structures. The connection between the box body 1 and the box cover 11 can also be designed with a waterproof structure or a sealing ring for waterproofing, but such structures belong to the common configuration of the docking device, so the description is simplified and no limitation is made.

[0046] The working principle of the present invention is:

[0047] The box body 1 of the device is provided with sealing joints 13 at both ends for fixing the cable 2, and a cutting groove 71 is provided in the middle of the device, and a groove 6 is provided on the cutting groove 71. The cutting blade 72 in the cutting groove 71 can slide along the long groove 712 on the surface of the cutting groove 71, and the cable 2 is pressed into the cutting groove 71. The cutting blade 72 can be used to cut the outer sheath of the cable 2 and strip the inner wire core 21. The mounting seat 5 located on both sides of the groove 6 is provided with a fixed wire structure 4 for fixing each wire core 21, and a plurality of wiring copper bars 51 are also provided for connecting the wire core 21.
