[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification and claims of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this utility model are defined according to the position of the structures in the drawings and the relative positions of the structures, and are only for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed by this utility model.

[0029] like Figures 1 to 5 and Figure 10 As shown, this utility model embodiment provides a servo power cable with magnetic attraction and fixing function, including a cable body 1. The cable body 1 includes an insulation protective layer (not shown) and multiple core wires (not shown) disposed inside the insulation protective layer. The cable body 1 generally adopts a three-phase four-wire system (i.e., the cable body 1 has three phase wires and one neutral wire) or a three-phase five-wire system (i.e., the cable body 1 has three phase wires, one neutral wire, and one ground wire). The cable body 1 is provided with a magnetic attraction fixing component 2, which includes a magnetic component 21 (i.e., the magnetic component 21 has magnetic force). The magnetic attraction fixing component 2 can fix (attract) the cable body 1 to a designated position through the magnetic force of the magnetic component 21. The designated position varies depending on the application scenario; for example, such as... Figure 10 As shown, the magnetic fastener 2 can magnetically attach the cable body 1 to the metal casing of the industrial equipment 3.

[0030] The servo power cable with the magnetic fixing function provided by the embodiment is provided with the magnetic fixing part 2 on the cable body 1, the magnetic fixing part 2 comprises the magnetic part 21 with magnetism, so that the magnetic fixing part 2 can fix the cable body 1 at a specified position by the magnetic force of the magnetic part 21, thereby facilitating the wiring of the servo power cable, avoiding the servo power cable from being scattered in the work site during wiring, improving the neatness of the work site, and avoiding the servo power cable from being mixed with other cables, reducing the electrical safety hazard (for example, avoiding short circuit). Meanwhile, the magnetic fixing method not only facilitates the fixing of the servo power cable (only needs to attract the magnetic fixing part 2 to the specified position), but also facilitates the dismounting of the servo power cable from the specified position, thereby facilitating use.

[0031] As an implementation form, the magnetic part 21 can be a magnet, a magnetic steel or the like, and the shape of the magnetic part 21 can be block-shaped or strip-shaped; the number of the magnetic part 21 can be one or more.

[0032] As shown in Figures 3 to 5 As an implementation form, the magnetic fixing part 2 further comprises the connecting part 22 connected with the cable body 1, and the magnetic part 21 is arranged on the connecting part 22. In use, the connecting part 22 is first connected with the cable body 1, and then the connecting part 22 is attracted and fixed at the specified position by the magnetic force of the magnetic part 21, so that the corresponding part of the cable body 1 is fixed at the specified position.

[0033] As an implementation form, the connecting part 22 is made of insulating material, thereby avoiding the magnetic fixing part 2 from being electrified, and further reducing the safety risk in use (for example, if the connecting part 22 is made of metal material, when the connecting part 22 is attracted and fixed on the metal shell of the industrial equipment 3, if the metal shell is electrified, the connecting part 22 will be electrified, so that the user may be electrocuted when touching the connecting part 22). In the embodiment, the connecting part 22 is a plastic part (i.e., made of plastic material), which is not only low in cost and convenient to manufacture, but also high in use safety. Of course, in other embodiments, if the service life is considered, the connecting part 22 can also be made of metal material under the condition of ensuring the safety of use scene.

[0034] As shown in Figures 3 to 5As shown, as an embodiment, the connecting piece 22 is fixed with the cable body 1 at least by clamping; the connecting piece 22 is provided with a clamping groove 22A, and the cable body 1 is clamped in the clamping groove 22A. The inner wall of the clamping groove 22A is a circular arc surface, and the inner wall of the clamping groove 22A is in close contact with the outer wall of the cable body 1 (the cable body 1 is in a cylindrical shape). In use, the connecting piece 22 can be installed on the cable body 1 only by clamping the cable body 1 in the clamping groove 22A; this clamping manner not only facilitates the installation and disassembly of the magnetic attraction fixing piece 2, but also facilitates the adjustment of the installation position of the magnetic attraction fixing piece 2 on the cable body 1. For example, in installation, the magnetic attraction fixing piece 2 can be moved along the length direction of the cable body 1 and / or rotated along the circumferential direction of the cable body 1, so as to adjust the installation position and installation direction of the magnetic attraction fixing piece 2.

[0035] As shown, Figures 3 to 5 As an embodiment, the connecting piece 22 comprises a connecting part 221 and a mounting part 222 which are connected with each other and are in an integrated structure. The connecting part 221 is in a C-shaped structure, the clamping groove 22A is arranged on the connecting part 221, that is, the connecting part 221 is clamped and fixed with the cable body 1, and one side of the connecting part 221 is provided with an opening 22B which is in communication with the clamping groove 22A; the mounting part 222 is located on the side of the connecting part 221 which is away from the opening 22B, and the magnetic member 21 is arranged on the mounting part 222.

[0036] Specifically, by arranging the opening 22B, in installation, the cable body 1 can be clamped in the clamping groove 22A only through the opening 22B, so as to facilitate the installation of the magnetic attraction fixing piece 2. At the same time, the distance H between the two ends of the connecting part 221 at the opening 22B is less than the diameter of the cable body 1 (that is, the central angle of the connecting part 221 needs to be greater than 180°), so as to avoid the cable body 1 from being separated from the opening 22B (that is, the connecting part 221 is tightly clamped with the cable body 1); at the same time, since the connecting piece 22 is made of plastic, it has a certain elasticity (of course, when the connecting piece 22 is made of other materials, such as metal, the connecting piece 22 also has a certain elasticity), when the cable body 1 is clamped in the clamping groove 22A through the opening 22B, the opening 22B will be expanded, so that the cable body 1 can enter the clamping groove 22A through the opening 22B.

[0037] As shown, Figures 3 to 5As shown, as an embodiment, the magnetic member 21 is embedded in the mounting portion 222, so as to avoid the abrasion of the magnetic member 21 caused by the exposure of the magnetic member 21, and slow down the magnetic force recession of the magnetic member 21. In the present embodiment, since the connecting member 22 is made of plastic, when the connecting member 22 is injection molded, the connecting member 22 can be injection molded on the basis of the magnetic member 21, so as to embed the magnetic member 21 in the mounting portion 222. Of course, in other embodiments, the magnetic member 21 can be installed in the mounting portion 222 after the connecting member 22 is injection molded.

[0038] As shown in Figure 6 and Figure 7 As another embodiment, the mounting portion 222 is provided with a mounting groove 2221 at the side away from the opening 22B, the magnetic member 21 is arranged in the mounting groove 2221, and the side wall of the magnetic member 21 away from the opening 22B does not exceed the groove of the mounting groove 2221 (i.e. the entire magnetic member 21 is located in the mounting groove 2221; in the present embodiment, the side wall of the magnetic member 21 away from the opening 22B is flush with the groove of the mounting groove 2221), so as to reduce or avoid the abrasion of the magnetic member 21; the inner wall of the mounting groove 2221 and the magnetic member 21 are fixed by glue (not shown in the figure). In this way, the installation of the magnetic member 21 and the mounting portion 222 can be facilitated. During installation, glue can be applied on the outer wall of the magnetic member 21 and / or the inner wall of the mounting groove 2221, and then the magnetic member 21 is arranged in the mounting groove 2221, so as to fix the magnetic member 21 and the inner wall of the mounting groove 2221 by glue.

[0039] As shown in Figure 8 and Figure 9 As another embodiment, the connecting portion 221 is provided with a first tongue portion 223 and a second tongue portion 224 at both ends of the opening 22B, the first tongue portion 223 and the second tongue portion 224 are integrated with the connecting portion 221, and the first tongue portion 223 and the second tongue portion 224 protrude towards the side away from the mounting portion 222. The magnetic attraction fixing member 2 further comprises a fastener 225, and the first tongue portion 223 and the second tongue portion 224 are connected by the fastener 225. The fastener 225 can be a screw and nut assembly; during installation, the cable body 1 is first clamped in the clamping groove 22A, and then the screw in the fastener 225 is passed through the first tongue portion 223 and the second tongue portion 224 (both the first tongue portion 223 and the second tongue portion 224 are provided with a hole position for the screw to pass through), and then the nut is tightened, so as to firmly connect the magnetic attraction fixing member 2 and the cable body 1 together. This connection mode can be applied to the case that the cable body 1 is thick and heavy, and can avoid the magnetic attraction fixing member 2 and the cable body 1 from falling off.

[0040] As shown in Figures 3 to 5As shown, as an embodiment, the side wall of the mounting portion 222 far away from the opening 22B is an adsorption surface 2220, which is a planar structure. That is, when the magnetic adsorption fixing member 2 is adsorbed to a specified position, the adsorption surface 2220 is in contact with the specified position. Since the adsorption surface 2220 is a planar structure, in most cases, the adsorption surface 2220 can be in contact with the surface of the specified position (for example, the metal shell of the industrial equipment 3), so as to ensure that the magnetic adsorption fixing member 2 has sufficient contact area with the specified position, and improve the stability of the magnetic adsorption. Of course, in other embodiments, according to different use scenarios (for example, the magnetic adsorption fixing member 2 needs to be adsorbed to a pipeline), the adsorption surface 2220 can also be provided in other shapes, for example, a concave arc surface structure.

[0041] As shown in Figure 1 and Figure 2 As an embodiment, a plurality of magnetic adsorption fixing members 2 are arranged on the cable body 1 at intervals. The interval between adjacent magnetic adsorption fixing members 2 can be set according to actual needs, for example, 0.5m-2m. The interval between adjacent magnetic adsorption fixing members 2 can be equal or not equal, which can be set according to actual needs. By arranging a plurality of magnetic adsorption fixing members 2, different positions of the cable body 1 can be fixed to specified positions.

[0042] As shown in Figure 10 As an embodiment, the use scenario of the servo power cable with magnetic adsorption fixing function can be that one end of the cable body 1 is connected to the industrial equipment 3 (for example, a machine tool), and the other end of the cable body 1 is connected to the power supply 4. Since the cable body 1 has a redundant length, if the part of the cable body 1 that is not used is not fixed, it will be scattered in the work site. By arranging a plurality of magnetic adsorption fixing members 2 on the part of the cable body 1 that is not used, the part of the cable body 1 that is not used can be adsorbed and fixed to the metal shell of the industrial equipment 3 (or other metal supports) by the plurality of magnetic adsorption fixing members 2. In this way, the part of the cable body 1 that is not used can be avoided to be scattered in the work site, the cleanliness of the work site is improved, and the cable body 1 and other cables or electrical equipment are avoided to be mixed together, so as to reduce the electrical safety hazard.

[0043] The servo power line with the magnetic attraction fixing function provided by the embodiment of the utility model has the magnetic attraction fixing part 2 arranged on the cable body 1, the magnetic attraction fixing part 2 can fix the cable body 1 at the specified position through the magnetic force of the magnetic part 21, thereby facilitating the wiring of the servo power line, not only can the servo power line be prevented from scattering in the work site when wiring, the cleanness of the work site is improved, but also the servo power line can be prevented from being mixed with other cables, the hidden danger of the power safety is reduced. Meanwhile, the magnetic attraction mode not only facilitates the fixing of the servo power line, but also facilitates the servo power line to be detached from the specified position, thereby facilitating the use.

[0044] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of the change or replacement within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
