Description

Technical Field

[0001] The invention relates to the technical field of cable installation and maintenance, and specifically provides a method for wiring cables in an electrical cabinet. Background Art

[0002] When wiring the existing electrical cabinet, the cable needs to be cut into a suitable length, bent into a suitable shape (such as a U-shape), and then connected to the copper bus, circuit breaker and other wiring terminals in the electrical cabinet.

[0003] The number of terminals in existing electrical cabinets is huge, and a large number of cables are required to connect the terminals to each other. Before installing the cables, a number of cables are usually cut according to the number of terminals, and then the cut cables are connected to the terminals respectively. When installing the cables, the staff will manually bend the cables and then install the bent cables to the terminals. However, the positions of the terminals such as copper bars in the electrical cabinet are different, and both ends of the cables need to be connected to the terminals, so the corresponding cable lengths are also different. In the case of similar cable lengths, it is easy for the staff to take the wrong cable. For example, if the length of the cable taken is less than the specified cable length, then when the two ends of the cable are connected to the terminals, the cable will be stretched, and the bending degree of the cable will change, which is easy to cause inconsistency after the cable wiring; if the cable is stretched a lot, it will also cause unstable cable connection. Therefore, when the installed cable length is not suitable, the cable needs to be removed and a cable of suitable length needs to be selected for installation. This situation of taking the wrong cable leads to the problem of inefficiency in the cable wiring of the electrical cabinet. Summary of the invention

[0004] The invention provides an electrical cabinet cable wiring method, which is used to solve the problem.

[0005] The technical solution of the present invention is as follows:

[0006] A method for wiring cables in an electrical cabinet comprises the following steps:

[0007] S1. Determine the length of the cable according to the distance between two corresponding wiring terminals, and cut the cable according to the determined length;

[0008] S2. When cutting the cable, a bending mark and an identification mark are set on the surface of the cable. The bending mark is used to indicate the bending position of the cable, and the identification mark is used to identify cables of different lengths to prevent the cable from being connected incorrectly to the terminal block.

[0009] S3. Bend the cable from the bending mark;

[0010] S4. Connect the two ends of the bent cable to the wiring terminals in the electrical cabinet respectively.

[0011] In this solution, identification marks corresponding to the wiring terminals are set on the cut cables. When workers pick up the cables, they can use the identification marks to determine which wiring terminals the cables correspond to, so as to avoid connecting the cables to the wrong positions and thus avoid rework, thus achieving the effect of improving wiring efficiency. Bending marks are set on the cables so that workers can bend the cables according to the positions of the bending marks, making the shape of the cables more uniform and beautiful after bending. After the cables are installed in the electrical cabinet, the shapes of the cables are uniform and beautiful, which also makes it easy to quickly find the cables corresponding to the wiring terminals during subsequent maintenance and repairs, reducing the difficulty of maintenance and repairs.

[0012] Preferably, a cutting tool is used to cut the cable, and the cutting tool is provided with at least two marking components, and the marking components are used to form a bending mark and an identification mark on the surface of the cable.

[0013] In this solution, by cutting the cable with a cutting tool, the length accuracy of the cut cable can be improved, and the length of the cut cable can be made consistent, so that the cables in the electrical cabinet are more neat and beautiful after wiring. At the same time, the cut cables are consistent in length, which can avoid the waste of cables caused by the cut cables being too long, thereby reducing the cost of the cables. In addition, in the process of cutting the cables, the bending marks and identification marks are set on the cables, and no separate operation is required, which will not cause the wiring operation to be too complicated and affect the wiring efficiency.

[0014] Preferably, the shearing tool comprises a fixed ruler, a knife holder and a blade, wherein the knife holder is slidably connected to the fixed ruler, the knife holder slides along the measuring length direction of the fixed ruler, and the blade is hinged to the knife holder so that the blade can rotate in the direction of the fixed ruler, and the cable is placed between the blade and the fixed ruler, and the blade cooperates with the fixed ruler to cut the cable.

[0015] In this solution, the knife holder can slide relative to the fixed ruler, so the position of the knife holder can be adjusted, so as to facilitate cutting cables of different lengths. When cutting the cable, the operator moves the knife holder according to the scale on the fixed ruler so that the scale where the blade is located is the same as the length of the cable to be cut, and then straightens the cable and places it between the fixed ruler and the blade, so that one end of the cable is flush with the zero point of the scale of the fixed ruler, and then presses the blade down with the foot to cut the cable. Because both ends of the cable are always straightened by hand, the length of the cut cable can be ensured to be accurate, and cutting the cable by foot can also make the operation of cutting the cable more labor-saving.

[0016] Preferably, the marking assembly includes a slider, a swing arm and a marking surface, the slider is slidably connected to the fixed ruler, the swing arm is hinged to the slider, the marking surface is arranged at the bottom of the swing arm, the marking surface is provided with paint, the swing arm swings toward the fixed ruler so that the marking surface contacts the cable surface, thereby forming an identification mark or a bending mark on the cable surface.

[0017] In this solution, the swing arm swings downward to contact the surface of the cable, thereby forming an identification mark or a bending mark on the surface of the cable. The function of the slider is to adjust the position of the fixed ruler in the measuring length direction. When the required cable length is different, the bending shape and bending position of the cable will also be different. Therefore, the position of the adjustment mark component can be adjusted according to the bending position of the corresponding cable.

[0018] Preferably, the same coating is used to form the bending mark for cables of different lengths, and different coatings are used to form the identification mark for cables of different lengths, and different coatings are used for the bending mark and the identification mark.

[0019] In this solution, the bending mark and the identification mark are distinguished by color, which can prevent bending at the wrong position; cables of different lengths can also be distinguished by the color of the identification mark to avoid bending the cables into the wrong shape and connecting the cables to other terminals. For example, if two cables of similar length are bent into a U shape, the cables can be quickly distinguished by the color of the identification mark, so that the cables can be connected to the correct position.

[0020] Preferably, it also includes a connecting rod, the swing arm and the blade are respectively provided with connecting holes, the connecting rod is connected to the connecting holes of the swing arm and the blade, the connecting rod is used to connect the swing arm and the blade, so that the blade and the swing arm rotate synchronously, thereby forming a bending mark and an identification mark on the surface of the cable while cutting the cable.

[0021] In this solution, the blade and the swing arm can be controlled simultaneously by the connecting rod, so that identification marks and bending marks are formed on the surface of the cable while cutting the cable, reducing the operation steps. No other operations are required when cutting the cable, which can avoid reducing the wiring efficiency.

[0022] In order to solve the problem that the identification mark is not obvious and is not easy to see and judge quickly, the identification mark is a reflective coating arranged on the surface of the cable, and the reflective coating forms reflected light under the light of the lamp.

[0023] In this solution, a reflective coating is provided on the surface of the cable, which can reflect light under the light. The reflected light is more eye-catching than the cable surface, making the identification mark more eye-catching. When the cable does not need to be identified, the identification mark can be turned off to prevent the identification mark from always reflecting and interfering with the sight.

[0024] In order to facilitate the distinction between different identification marks, cables of different lengths are provided with different reflective coatings, and the different reflective coatings form reflected light of different colors under the light.

[0025] In this solution, different identification marks can be distinguished by color, so cables of different lengths can be quickly distinguished.

[0026] In order to more quickly determine which wiring terminals the cables correspond to, the cables and the corresponding wiring terminals are provided with the same reflective coating, and the cables with the same reflective color are picked up according to the reflective color of the wiring terminals.

[0027] In this solution, an identification mark corresponding to the cable is set on the wiring terminal, and the position where the cable should be connected can be quickly determined by the reflective color, which can improve the cable connection efficiency.

[0028] During subsequent repair and maintenance of the electrical cabinet, it is possible to replace the cables on the terminal blocks. In order to solve the problem of cable confusion caused by the different lengths of the replaced cables, a coating plate is set in the electrical cabinet. The coating plate is coated with paint layers corresponding to various identification marks, and the position of each paint layer records the length of the corresponding cable.

[0029] In this solution, a coating plate is set in the electrical cabinet. When the electrical cabinet needs to be maintained and repaired, the cables and terminal blocks are illuminated by light. The required length of each cable can be determined by comparing the reflective color of the cables and terminal blocks with the color on the coating plate. The cables can be cut as needed to keep the replaced cables consistent with the non-replaced cables, which avoids cable clutter and facilitates subsequent maintenance and repair.

[0030] Beneficial effects of the present invention:

[0031] The present invention provides identification marks on the cables, which can avoid mismatching between the cables and the wiring terminals, avoid rework problems, and improve the wiring efficiency of the electrical cabinet. Setting bending marks on the cut cables can make the bending shapes of the cables more uniform, making the cables in the electrical cabinet neat and beautiful after installation, and also facilitating quick cable locating in subsequent maintenance and repair.

[0044] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely described through specific implementation methods of the embodiments of the present invention.

[0045] Embodiment 1:

[0046] like Figure 1 As shown, this embodiment 1 provides a method for wiring cables in an electrical cabinet. Before wiring the electrical cabinet, the cables need to be processed, including the following steps:

[0047] S1. Determine the length of the cable according to the distance between two corresponding wiring terminals, and cut the cable according to the determined length; if the distance between the two wiring terminals is close, the cut cable length is short, and if the distance between the two wiring terminals is far, the cut cable length is long;

[0048] S2. When cutting the cable, a bending mark and an identification mark are set on the surface of the cable. The bending mark is used to show the bending position of the cable, and the identification mark is used to identify cables of different lengths to prevent the cable from being connected to the terminal by mistake. For example, the cable needs to be connected to the terminal with both ends facing up. In this case, the cable needs to be bent into a U shape. If the heights of the two terminals are different, the bending position is not located in the middle of the cable. Therefore, it is necessary to determine the bending position according to the position of the terminal, and set a bending mark at the bending position to ensure that the bending position of the cable is consistent and the shape of the cable after bending is the same. The shape of the cable after bending is the same. When the bent cable is installed in the electrical cabinet, the shape of the cable in the electrical cabinet is unified, which is convenient for finding the cable during subsequent maintenance and repair. Since the number of cables that need to be connected in the electrical cabinet is large, after cutting the cable and bending the cable, it is also necessary to connect the bent cable to the correct position. The cable lengths corresponding to different terminals are different. If the shapes of the cables after bending are similar, the length of the cable is difficult to intuitively judge after bending, and it is easy to have the problem that the length of the terminal and the connected cable do not correspond. When the length of the wiring terminal does not correspond to the cable, the cable needs to be removed and the correct cable needs to be found for installation, which is time-consuming and laborious. After the identification mark is set on the surface of the cable, the correspondence between the cable and the wiring terminal can be determined according to the identification mark, avoiding the situation where the wiring terminal does not correspond to the cable, thereby improving the wiring efficiency of the electrical cabinet;

[0049] S3. Bend the cable at the bending mark. The cable can be bent using a manual bending machine currently available on the market. The cable can be bent into a desired shape using the manual bending machine.

[0050] S4. Determine the installation position of the cable according to the identification mark, and connect the two ends of the bent cable to the wiring terminals in the electrical cabinet respectively.

[0051] like Figure 2 As shown, when the cable is cut in step S1, the length of the cut cable is determined according to the position of the wiring terminal, and the bending position of the cable is determined according to the positions of the two wiring terminals. After the cable length is determined, a shearing tool is used to cut the cable of the specified length.

[0052] like Figure 3 and Figure 4As shown, the shearing tool includes a fixed ruler 1, a knife holder 5, a blade 6, a marking assembly and a connecting rod 8. The knife holder 5 is slidably connected to the fixed ruler 1, and one end of the blade 6 is hinged to the fixed ruler 1. At least two marking assemblies are provided on the fixed ruler 1, that is, at least one marking assembly on the fixed ruler 1 is used to form an identification mark on the cable, and at least one marking assembly is used to form a bending mark on the cable. When the cable needs to be bent at multiple locations, a marking assembly can be added to form multiple bending marks on the cable at the same time. The fixed ruler 1 is provided with a scale, and the scale is arranged along the length direction of the fixed ruler 1. The fixed ruler 1 is used to measure the length of the cable.

[0053] like Figure 5 and Figure 6 As shown, the marking assembly includes a slider 2, a swing arm 3 and a marking surface. The slider 2 is slidably connected to the fixed ruler 1, and one end of the swing arm 3 is slidably connected to the slider 2. The marking surface is arranged on the lower side of the swing arm 3. When the lower side of the swing arm 3 is against the cable, the marking surface contacts the cable, thereby forming an identification mark or a bending mark on the surface of the cable. The slider 2 is slidably connected to the fixed ruler 1, which is convenient for adjusting the position of the marking slider 2, thereby changing the position of the bending mark formed on the cable by the marking slider 2. The cable is cut by a blade 6, and the knife seat 5 is slidably arranged on the fixed ruler 1. The position of the blade 6 on the fixed ruler 1 can be adjusted to cut cables of different lengths. After adjusting the position of the knife, the cable of the required length can be quickly cut off to improve efficiency. When measuring the length of the cable, one end of the cable is flush with the end of the fixed ruler 1, and the cable is extended along the length direction of the fixed ruler 1, and then the blade 6 is controlled to cut. Because the position of the blade 6 has been adjusted in advance, the length of the cut cable is sufficiently accurate. The effect of connecting rod 8 is to connect blade 6 and swing arm 3, so that blade 6 and swing arm 3 can swing simultaneously. That is to say, when blade 6 cuts off cable, marking assembly forms bending mark on cable simultaneously.

[0054] Specifically, the cable is placed between the blade 6 and the fixed ruler 1, and the blade 6 is pressed to move toward the fixed ruler 1, thereby cutting the cable to achieve the effect of cutting off the cable.

[0055] The blade 6 and the swing arm 3 are both provided with a connecting hole 9, and the connecting rod 8 passes through the connecting hole 9, so that the blade 6 and the swing arm 3 are connected to each other through the connecting rod 8. Therefore, when the connecting rod 8 is pressed downward, the knife handle and the swing arm 3 will swing downward at the same time. In addition, pressing the connecting rod 8 downward by foot also makes it easier to cut the cable.

[0056] The fixed ruler 1 can be provided with an anti-skid step 7, and the anti-skid step 7 and the knife seat 5 are respectively located on both sides of the fixed ruler 1 to prevent the cable from sliding along the fixed ruler 1 when cutting the cable. The scale of the fixed ruler 1 is set on the top surface of the anti-skid step 7. Since the marking surface only needs to contact the cable on one side of the anti-skid step 7, the area of ​​the marking surface can be controlled so that the marking surface will not contact the top surface of the anti-skid step 7, thereby avoiding the problem of unclear scale caused by the paint on the marking surface.

[0057] When using the cutting tool, the operator holds the cable with both hands to keep the cable parallel to the fixed ruler 1, and then presses the connecting rod 8 by pedaling to cut the cable and leave a bending mark on the surface of the cable.

[0058] The functions of the identification mark include distinguishing cables of different lengths and determining the location where the cable is connected. When distinguishing cables of different lengths, different identification marks need to be set on different cables.

[0059] Optionally, a slide rail 4 is provided on the fixed ruler 1, and the knife seat 5 and the slide block 2 are respectively slidably connected to the slide rail 4. The slide rail 4 can also enhance the strength of the fixed ruler 1 and prevent the fixed ruler 1 from being bent and damaged.

[0060] A paint block 10 is disposed at the lower side of the swing arm 3, and the paint block 10 is detachably connected to the swing arm 3. The marking surface is the bottom surface of the paint block 10. After the paint block 10 is removed, the swing arm 3 cannot form an identification mark or a bending mark on the surface of the cable, that is, the number of bending marks or identification marks on the cable can be controlled by removing or installing the paint block 10 without removing the marking component, thereby reducing the difficulty of operation.

[0061] The paint block 10 includes a shell and a paint layer. The paint layer can be a structure such as a sponge or a brush soaked in liquid paint. The paint layer is fixedly connected to the shell, and the shell is used to connect to the swing arm 3. For example, a groove is set at the bottom of the swing arm 3, and the shell is stuck in the groove. A magnet can also be set at the bottom of the swing arm 3 to further prevent the paint block 10 from falling off. Similarly, the groove can also be a structure such as a dovetail groove, which can also prevent the paint block 10 from falling off.

[0062] Providing the paint block 10 also facilitates the marking component to form identification marks of different colors. When it is necessary to form identification marks on cables of different lengths, it is only necessary to replace the paint block 10 at the bottom of the swing arm 3.

[0063] Because the cross-section of the cable is circular, the paint layer can be deformed inward under pressure. The concave paint layer can increase the contact area with the cable surface, thereby increasing the coating area formed on the cable surface and making the identification marks on the cable surface easier to observe. This is used to solve the problem of inconspicuous identification marks, facilitate quick identification by operators, and improve wiring efficiency.

[0064] In step S3, a bending tool is used to bend the cable. The bending tool can be a manual bending machine in the prior art. The shape of the cable after bending by the manual bending machine is more uniform, which makes the wiring in the electrical cabinet more beautiful and facilitates the rapid sorting out of the cable direction during subsequent maintenance, thereby improving maintenance efficiency.

[0065] Embodiment 2:

[0066] The second embodiment provides a method for wiring cables in an electrical cabinet. The difference from the first embodiment is that the identification mark in the second embodiment is different. The identification mark in the second embodiment is a reflective coating.

[0067] Under lighting, the reflective coating can reflect light. In other words, under lighting, the identification mark with the reflective coating is more conspicuous and easier to distinguish. The same coating can be applied to the terminal block, and under lighting, the terminal block and the corresponding cable reflect the same color of reflected light, so that the operator can find the cable corresponding to the terminal block more quickly, improving wiring efficiency. Since the terminal block in the electrical cabinet includes many copper bars, and the copper bars usually connect several cables, and the cables are the same length and shape, these cables with the same length and shape will be set with the same identification mark, that is, a reflective coating that reflects the same color of reflected light.

[0068] After the wiring is completed, the electrical cabinet will also be maintained and repaired during use. During the maintenance and repair, the cables may need to be replaced. If the length and bending shape of the replaced cables are different, the cable wiring in the electrical cabinet will no longer be neat. If it has been maintained and repaired many times, it will further cause the wiring in the electrical cabinet to be chaotic, increasing the difficulty of sorting out the cables during maintenance and repair, and reducing efficiency.

[0069] To this end, the second embodiment further provides a coating plate in the electrical cabinet, on which reflective coatings of various colors are provided, and the length and bending position of the corresponding cable are recorded at each reflective coating. During maintenance, the color of the reflective coating on the terminal block can be observed by lighting, and then the length and bending position of the cable to be replaced can be determined by comparing the color of the reflective coating on the coating plate. The shape of the cable can be determined based on the shape of the cable in the connected state in the electrical cabinet, and the bending position can be the distance from the cable end to the bending mark.

[0070] Embodiment three:

[0071] The third embodiment provides a method for wiring cables in an electrical cabinet. The difference from the first embodiment is that the width of the coating layer used as an identification mark in the third embodiment is different, and the connection position of the cable is distinguished by the width.

[0072] In the third embodiment, the width of the coating layer on the cable is set according to the height of the wiring terminal in the electrical cabinet. For example, the cable connected to the lowest wiring terminal corresponds to the narrowest coating layer, and the higher the height of the wiring terminal, the larger the corresponding coating layer width. Therefore, when connecting the cable, the coating layer width of the cable can be compared with the coating layer width of the lower cable to determine whether the cable is connected to the right position.

[0073] It should be noted that the width of the coating layer refers to the dimension along the cable axis.

[0074] The connection positions of the cables are distinguished by setting paint layers of different widths. This setting method does not require setting paint layers of the same color at the wiring terminals. The cable corresponding to the wiring terminal can be determined only by the width of the paint layer and the height of the wiring terminal.

[0075] In actual operation, the cables can be connected gradually from the bottom of the electrical cabinet upward. The coating width on the cable at the bottom is the smallest, so the cable with the smallest coating width can be directly selected for connection. After the cables are connected to the terminals at the bottom, the cables with the smallest coating width are all used up. At this time, the cables with the smallest coating width can be selected from the remaining cables for installation. Installing from bottom to top can prevent the cables from being connected to the wrong terminals.

[0076] Similarly, when connecting the terminal blocks and cables, they can also be connected in a top-down order.

[0077] Similarly, the coating layer width sequence may also be changed, for example, the cable with the smallest coating layer width corresponds to the uppermost terminal, and the cable with the largest coating layer width corresponds to the lowermost terminal.

[0078] To form paint layers of different widths on the cable surface, paint blocks 10 of different widths can be installed in the groove on the lower side of the swing arm 3. The paint blocks 10 of different widths contact the cable surface to form paint layers of different widths on the cable surface.

[0079] The width of the paint layer and the color of the paint layer can be used in combination. When there are many layers of terminal blocks in the electrical cabinet, the combination of color and width can easily determine the connection position of the cable, and can also reduce the demand for paint types, which is convenient for cost control. For example, when the terminal blocks form 9 layers in the electrical cabinet, the 9 layers of terminal blocks can be respectively corresponded to 3 different colors of paint, and each color of paint corresponds to 3 layers of terminal blocks. Cables with the same paint color can be distinguished by the width of the paint layer. Among the terminal blocks corresponding to the color paint, the cable paint layer width corresponding to the bottom terminal is the smallest, and the cable paint layer width corresponding to the top terminal is the largest. In this case, only three colors of paint and three different widths of paint blocks 10 are needed to distinguish the 9 layers of terminal blocks, and the number of paint types and paint blocks 10 is small, which is convenient for cost control.

[0080] The third embodiment can also be applied to the second embodiment.

[0081] Embodiment 4:

[0082] The fourth embodiment provides a method for wiring cables in an electrical cabinet. The difference from the first embodiment is that the number of coating layers used as identification marks in the fourth embodiment is different.

[0083] For example, the cable corresponding to the bottommost terminal is provided with one coating layer as an identification mark. The cable corresponding to the second-layer terminal at the bottom is provided with two coating layers as identification marks. Similarly, the number of coating layers on the cable corresponding to each layer of terminal upwards gradually increases, the third-layer terminal at the bottom corresponds to 3 coating layers, the fourth-layer terminal at the bottom corresponds to 4 coating layers, and so on. When connecting the cable, observe which layer the terminal belongs to in the vertical direction, and then count the number of coating layers as reference marks to determine the connection position of the cable.

[0084] When there are too many layers of paint, it is easy to cause eye fatigue of the operator. Therefore, the number of paint layers can be reduced by matching the color and the number, so as to avoid eye fatigue of the operator caused by too many layers of paint. For example, when the terminal blocks form 9 layers in the electrical cabinet, the 9 layers of terminal blocks can be respectively corresponded to 3 different colors of paint, and each color of paint corresponds to 3 layers of terminal blocks. Cables with the same paint color can be distinguished by the number of paint layers. Among the terminal blocks corresponding to the color paint, the number of cable paint layers corresponding to the bottom terminal is one, and the number of cable paint layers corresponding to the top terminal is three. In this case, it is only necessary to form a maximum of 3 layers of paint on the cable with three colors of paint as identification marks to distinguish the 9 layers of terminal blocks. The number of paint layers is minimal, and the operator's eyes will not be fatigued due to too many layers of paint.

[0085] Embodiment five:

[0086] The fifth embodiment provides a method for wiring cables in an electrical cabinet. Different from the first embodiment, the fifth embodiment further includes a positioning clamp.

[0087] The function of the positioning pliers is to position the cable to be connected so that the contact length between the cable and the terminal is the same. The advantage of this setting method is that it can avoid the cable loosening due to insufficient contact length between the cable and the terminal, and can also unify the cable connection length, making the cables in the electrical cabinet more neat and beautiful.

[0088] The positioning clamp includes a back plate 11 and a plurality of jaws 12, each jaw 12 is arranged on the back plate 11 along a straight line, each jaw 12 is used to clamp the cable, each jaw 12 is respectively provided with an alignment mark, the alignment mark is used to align the identification mark on the cable, and the alignment marks on each jaw 12 are located on the same line. When the marking component forms the identification mark on the surface of the cable, the spacing between the identification mark and the end of the cable is the same. When the jaw 12 is used to clamp the cable, the edge of the identification mark close to the end of the cable can be aligned with the alignment mark, so that the edges of the identification marks of each cable are located on the same straight line, and then the back plate 11 is moved to insert the ends of each cable into the wiring terminal at the same time, and then each wiring terminal is tightened respectively to connect the wiring terminal with the cable. Because the cable has been fixed and aligned before the wiring terminal, therefore, during the connection process, each cable is also in an aligned state, so that the contact length of each cable with the wiring terminal is the same, ensuring that the cable will not be too short in contact with the wiring terminal and loose, and can ensure that each cable is neat and beautiful after connection.

[0089] Furthermore, after clamping each cable with the positioning pliers, multiple cables can be inserted into each terminal at one time, reducing the number of cable insertions; there is no need to fine-tune the position of each cable when connecting each cable, reducing the number of times the cable position is fine-tuned, thereby achieving the effect of improving the cable installation efficiency.

[0090] Each jaw 12 is an arc-shaped open ring, and the jaw 12 presses the surface of the cable from the side by its own elasticity, thereby achieving the effect of clamping the cable. When the cable is clamped into the jaw 12, the jaw 12 will cause plastic deformation, and the elastic force generated by the deformation of the jaw 12 will press the surface of the cable, thereby achieving the effect of fixing the cable.

[0091] The alignment mark may be a structure such as a line, a boss, or a groove provided on the jaw 12. In one embodiment, the alignment mark may be the top surface of the jaw 12. The top surfaces of the jaws 12 are flush with each other. When the jaws 12 clamp the cable, the edge line of the identification mark on the cable close to the cable end is flush with the top surface of the jaw 12, so that the cables can be aligned.
