Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a hybrid cable and a handheld laser welding device. Background Technology

[0002] Existing wiring harness solutions for providing optical, electrical, and pneumatic power to handheld welding torches are split-type solutions. This involves using several independent functional cables—fiber optic armored tubing, PU gas tubing, and signal transmission cable—which are then bundled together into a single wiring harness for use with the welding torch after being wrapped in cloth or other plastic sheathing materials. Figure 1 As shown, however, this cable structure has the following problems:

[0003] 1. Several or more sets of independent functional cables are needed to provide optical, electrical, and pneumatic functions. After being bundled together, the diameter is ≥20mm, the cable bundles are messy, bulky, and inconvenient to use.

[0004] 2. Due to the scattered nature of the wire harnesses, they are prone to tangling and twisting, making them unsuitable for high-intensity bending operations.

[0005] 3. Each individual cable needs to be produced, purchased, and cut separately, which increases the factory's production, processing, and procurement costs. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a hybrid cable and handheld laser welding equipment to solve the problems of messy and poor bending performance of existing split cable harnesses.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] On the one hand, a hybrid cable is provided, including an outer sheath, a cable assembly, and a positioning component, wherein the cable assembly is disposed within the outer sheath, and the positioning component, made of an elastic material, is disposed between the cable assembly and the outer sheath;

[0009] The cable group includes a main cable and several cables distributed on the outer periphery of the main cable. The positioning component includes several positioning elements, which are distributed in the gap between the main cable, the several cables and the outer sheath and support the several cables, so that the cables maintain a distance from the main cable and / or between adjacent cables among the several cables.

[0010] In a possible implementation, the outer layer includes an outer sheath layer and a first metal braid layer arranged from the outside to the inside.

[0011] In a possible implementation, the plurality of cables includes a cable one, which includes a protective layer, a shielding layer, and a signal line group arranged from the outside to the inside.

[0012] In a possible implementation, the cable one further includes a first non-woven fabric layer disposed inside the shielding layer;

[0013] The signal line group includes multiple signal lines and several first positioning ropes distributed in the gaps between the multiple signal lines and the first non-woven fabric layer.

[0014] In a possible implementation, the protective layer is made of polyurethane tape, and / or the positioning element is a second positioning rope.

[0015] In a possible implementation, the outer sheath layer may further include a paper tape layer disposed between the outer sheath layer and the metal braided layer, and a nonwoven fabric layer disposed inside the metal braided layer.

[0016] In a possible implementation, the main cable includes a first main cable and a second main cable, the first main cable abutting against or separated from the second main cable by the positioning element, and both of their outer diameters being larger than the outer diameters of the plurality of cables.

[0017] In one possible implementation, the first main cable is an air pipe, and the second main cable is an optical fiber cable.

[0018] In a possible implementation, the second main cable includes a Teflon layer, a second metal braid layer, and an optical fiber core arranged from the outside to the inside.

[0019] In a possible implementation, the main cable includes a first main cable and a second main cable, the first main cable abutting against or separated from the second main cable by the positioning element, and both of their outer diameters being larger than the outer diameters of the plurality of cables.

[0020] On the other hand, a handheld laser welding device is also provided, including a welding host, a handheld welding torch and a hybrid cable as described in any of the above technical solutions, the hybrid cable connecting the welding host and the handheld welding torch.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This utility model relates to a hybrid cable and a handheld laser welding device. By arranging the remaining cables around the main cable and cooperating with positioning components that are set in the gaps between the main cable, the other cables, and the outer sheath to form intervals, it can effectively reduce twisting and deformation during use and improve the stability and toughness of each cable within the outer sheath, making it suitable for use in high-intensity work environments.

[0023] Furthermore, by setting a first metal braided layer inside the outer sheath, the cable's anti-interference performance can be improved, the accuracy of lost signals can be reduced, and by using such a layout structure for the three functional cables (optical, electrical, and electronic), they can be bundled together from the production process through twisting, allowing them to be manufactured by automated equipment like ordinary cables. This effectively reduces production costs, improves the overall production efficiency and consistency of the welding torch, and ensures that the product can adapt to high-intensity operations.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0029] Please refer to Figure 1 As shown, an embodiment of this application provides a hybrid cable, including an outer sheath 1, a cable group, and a positioning component. The cable group is disposed within the outer sheath 1, and the positioning component, made of an elastic material, is disposed between the cable group and the outer sheath 1. The cable group includes a main cable 2 and a plurality of cables distributed on the outer periphery of the main cable 2. The positioning component includes a plurality of positioning elements 5, which are distributed in the gaps between the main cable 2, the plurality of cables, and the outer sheath 1 and support the plurality of cables, so that the cables maintain a distance from the main cable 2 and / or between adjacent cables among the plurality of cables.

[0030] The cable group inside the outer sheath 1 includes multiple cables, with one cable as the main cable 2 and the remaining cables distributed around it. This layout helps to maintain relative stability between the cables. Furthermore, several positioning elements 5 made of flexible or elastic materials are set in the gaps between the main cable 2, the cables, and the outer sheath 1 to support the cables and form intervals. This further stabilizes the positions of the main cable 2, the cables, and the outer sheath 1 and provides effective positioning. It also supports and maintains a certain interval between the cables and the main cable 2 and / or between adjacent cables. When the mixed cable is bent, twisted, or dragged, the gap is reduced by the internal cables squeezing the flexible positioning elements 5, thus providing higher toughness.

[0031] It is understood that the positioning element 5 can either maintain a gap and provide support between the cable and the main cable 2, or maintain a gap between adjacent cables among the plurality of cables, or maintain a gap simultaneously. All of these structures can enable the hybrid cable to have good toughness. The positioning element 5 provides support between the cable and the main cable 2 and / or between adjacent cables among the plurality of cables from the beginning to the end of the hybrid cable. Therefore, the positioning element 5 can be a rope-like shape similar to the shape of the cable, a ball-like shape fixed therebetween, or other shapes that can provide elastic support, without limitation.

[0032] By using the above technical solution, the remaining cables are arranged with the main cable 2 as the center, and with the positioning components set in the gaps between the main cable 2, several cables and the outer sheath 1 to form intervals, the torsion and deformation during use can be effectively reduced and the stability and toughness of each cable in the outer sheath 1 can be improved, making it suitable for use in high-intensity work environments.

[0033] In one embodiment, the outer layer 1 includes an outer sheath layer 11 and a first metal braided layer 13 arranged from the outside to the inside.

[0034] In this way, by providing a first metal braided layer 13 on the inner side of the outer layer 11, the first metal braided layer 13 can have good toughness due to the certain shrinkage brought by the braided structure, and can also play a shielding role, ensuring its use in high-intensity scenarios. Specifically, the first metal braided layer can be made of copper foil wire.

[0035] Furthermore, in combination Figure 2 As shown, the plurality of cables includes cable 4, which includes a protective layer 41, a shielding layer 42, and a group of signal lines 44 arranged from the outside to the inside.

[0036] In this way, cable 4 is a signal cable, with its protective layer 41 providing protection, and the shielding layer 42 shielding the signal to reduce signal loss or interference from external signals. The inner signal wires 44 are the core wires of cable 4. This structure makes the cable more stable and less prone to damage. Specifically, the shielding layer 42 is made of aluminum foil. Cable 4 can also be used as a power cable.

[0037] To ensure that the internal structures have a certain relative movement space and that the internal sub-lines can be relatively stable, the cable 4 further includes a first non-woven fabric layer 43 disposed inside the shielding layer 42; the signal line 44 group includes multiple signal lines 44 and several first positioning ropes 45 distributed in the gaps between the multiple signal lines 44 and the first non-woven fabric layer 43.

[0038] In this way, the first nonwoven fabric ensures that the internal structures have a certain relative movement space, and together with the protective layer 41, it can better meet a certain relative movement under bending and other conditions to improve toughness. At the same time, the signal line 44 group can be positioned by the first positioning rope 45 to maintain good stability.

[0039] Specifically, the first positioning rope 45 is made of an elastic material. Preferably, the first positioning rope 45 is an existing composite cotton rope with a certain degree of elasticity. Meanwhile, the protective layer 41 can be made of polyester tape. The polyester not only provides relative movement but also protects the single-sided aluminum foil shielding layer 42 from damage during the cabling process.

[0040] Preferably, the positioning element 5 is a second positioning rope, which is made of elastic material and also uses an existing composite cotton rope with a certain degree of elasticity.

[0041] In addition, it may include cable 2 3, the outer sheath 11 of cable 2 3 is the same as cable 1 4 and is also spaced by positioning member 5. This cable is also a signal cable and serves as an electrical signal cable for physical transfer.

[0042] In another implementation structure, such as Figure 3 As shown, more cables can be installed, and positioning parts 5 of appropriate size can be selected to fill and support the internal gaps.

[0043] In embodiments of this application, the outer sheath 1 further includes a paper tape layer 12 disposed between the outer sheath 11 and the metal braided layer, and a non-woven fabric layer 14 disposed inside the metal braided layer.

[0044] The non-woven fabric layer 14 and the paper tape layer 12 are used to ensure that the internal structures have a certain relative movement space, and together with the first metal braided layer 13, the outer layer 1 can have better toughness.

[0045] In an embodiment of this application, a hybrid cable is used to connect the main unit of a laser welding machine and the welding torch. In this case, the main cable 2 includes a first main cable 21 and a second main cable 22. The first main cable 21 abuts against or is spaced apart from the second main cable by the positioning member 5, and the outer diameter of both is larger than the outer diameter of the plurality of cables.

[0046] Using two main cables 21 and 22 with larger outer diameters as main cables 2, the outer sheath 1 can be supported. By placing the remaining cables in the gap between the main cables 2 and the outer sheath 1, a better structural arrangement can be achieved, and the stability of the internal structure of the cable can be improved.

[0047] Specifically, the first main cable 21 is an air pipe, and the second main cable 22 is an optical fiber cable.

[0048] Based on this, the second main cable 22 includes a Teflon layer 221, a second metal braided layer 222, and an optical fiber core 223 arranged from the outside to the inside. As an optical fiber cable, the second main cable 22 provides better protection in terms of high temperature resistance, corrosion resistance, and insulation through the Teflon layer 221, and the second metal braided layer 222 also gives the second main cable 22 better toughness.

[0049] Embodiments of this application also provide a handheld laser welding device, including a welding host, a handheld welding torch, and a hybrid cable as described in any of the above technical solutions, wherein the hybrid cable connects the welding host and the handheld welding torch.

[0050] This embodiment proposes a structural design that combines optoelectronic, electrical, and other functional cables through a stranding process. This allows the cables to be manufactured using automated equipment, similar to ordinary cables. During the stranding process, cotton rope, copper foil, and other auxiliary materials are used between the different cables to increase their toughness, ensuring they can withstand high-frequency, high-intensity bending, twisting, and dragging after completion. Furthermore, by incorporating internal aluminum foil, high-density metal braided mesh, and shielding ground wires, the cable's anti-interference performance is improved, protecting signals from external interference during transmission over distances of 10 to tens of meters and reducing signal loss.

[0051] By redesigning and integrating various functional cables and utilizing existing special cable manufacturing technologies, different cables are bundled into a single, independent opto-electric hybrid special cable during the production process. This not only effectively reduces production costs and improves the overall production efficiency and consistency of the welding torch, but also enhances product quality and reduces enterprise costs while ensuring the product's adaptability to high-intensity operations.

[0052] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
