Abstract
Description
Technical Field
[0001] This application relates to the technical field of wire materials, and particularly to a wire material for a three-dimensional laser scanner. Background Art
[0002] A three-dimensional laser scanner is a scientific instrument used to detect and analyze the shape and appearance data of objects or environments in the real world. The data collected is often used for three-dimensional reconstruction calculations, and then a digital model of the actual object is created in the virtual world. This technology has relatively wide applications in industrial design, defect detection, reverse engineering, topographic surveying, archaeological fields, etc.; according to different carriers, three-dimensional laser scanners can be divided into handheld, airborne, vehicle-mounted, and ground-mounted types.
[0003] Among them, a handheld three-dimensional laser scanner usually includes a scanner main body, a laser lens, and two camera lenses. The laser lens and the camera lenses are arranged on the scanner body. The information collected by the camera lenses is transmitted to a computer through a USB3.0 wire. Since the laser lens consumes a large amount of power, it requires a separate power cord. The two wires are separately connected to the scanning instrument. During the process of handling, installation, and use, the wires are prone to twisting. The two wires are stressed unevenly and need to be frequently arranged, seriously affecting the use experience. Utility Model Content
[0004] In order to solve the above technical problems, this application provides a wire material for a three-dimensional laser scanner, including a signal transmission line and a power cord. The outer periphery of the signal transmission line is coated with a first outer sheath, the outer periphery of the power cord is coated with a second outer sheath, and the outer peripheral surfaces of the first outer sheath and the second outer sheath are partially connected.
[0005] Preferably, the first outer sheath and the second outer sheath are connected by a connecting block, and the first outer sheath, the second outer sheath, and the connecting block are integrally formed.
[0006] Preferably, the width of the connecting block is 0.4 - 0.5 mm, and the thickness is 0.3 - 0.4 mm.
[0007] Preferably, the signal transmission line includes several groups of signal wire groups and a braided layer covering the signal wire groups.
[0008] Preferably, each signal wire group includes two twisted core wires, a ground wire, a shielding layer, and a heat-melt polyester tape covering the outer periphery.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.
[0018] Embodiment
[0019] To solve the above technical problems, this embodiment provides a wire for a three-dimensional laser scanner, as Figure 1As shown in the figure, it includes a signal transmission line 10 and a power line 20. The outer periphery of the signal transmission line 10 is coated with a first outer covering layer 31, and the outer periphery of the power line 20 is coated with a second outer covering layer 32. The outer peripheral surfaces of the first outer covering layer 31 and the second outer covering layer 32 are partially connected. After the first outer covering layer 31 and the second outer covering layer 32 respectively coat the signal transmission line 10 and the power line 20, by integrating the first outer covering layer 31 and the second outer covering layer 32 into one body, the signal transmission line 10 and the power line 20 are relatively fixed and combined into one whole, improving the stress strength of the wire, and at the same time, the wire will not twist during use and movement. The overall design structure also makes the wire stress evenly and has better bending resistance performance.
[0020] Specifically, the first outer covering layer 31 and the second outer covering layer 32 are connected by a connecting block 33, and the first outer covering layer 31, the second outer covering layer 32 and the connecting block 33 are integrally formed. In some embodiments, both the first outer covering layer 31 and the second outer covering layer 32 are made of flame-retardant PVC material with a temperature resistance of -40 to 80 °C and a hardness of 80A. The first outer covering layer 31, the connecting block 33 and the second outer covering layer 32 are integrally extruded by an extruder, so that the first outer covering layer 31 and the second outer covering layer 32 respectively coat the signal transmission line 10 and the power line 20, and the first outer covering layer 31 and the second outer covering layer 32 are connected into one body through the connecting block 33, making the signal transmission line 10 and the power line 20 connected into one whole, with better bending resistance performance, and it can ensure that signal transmission and power supply are not affected after 3000 times of bending (test conditions: hanging weight 500 grams, bending angle ±90°, frequency 40 cycles per minute, bending radius 12.7 mm).
[0021] Furthermore, the width of the connecting block 33 is 0.4 - 0.5 mm, and the thickness is 0.3 - 0.4 mm. Preferably, through multiple tests and verifications, the width and thickness of the connecting block 33 are 0.4 mm and 0.3 mm respectively to achieve the most perfect effect, ensuring the connection strength and the characteristics of easy separation during processing.
[0022] Furthermore, the signal transmission line 10 includes several groups of signal line groups 11 and a braided layer 12 covering the signal line groups 11. The braided layer 12 is woven with 0.08 mm - 0.1 mm tinned copper wire. Preferably, 0.08 mm tinned copper wire is used to enhance the EMI effect of the wire, shield external interference with the power line 20, and at the same time improve the anti-fatigue and stress strength of the wire.
[0023] In the above solution, as Figure 2As shown, the signal wire group 11 includes two twisted core wires 111, a ground wire 112, a shielding layer 113 wrapped around the periphery, and a heat-melt polyester tape 114. The shielding layer 113 is made of aluminum foil. After the two core wires 111 and one ground wire 112 are twisted together, they are shielded by the shielding layer 113 to prevent signal leakage and shield external interference. The outermost heat-melt polyester tape 114 wrapped around plays the role of insulation and fixing the structure. Among them, the conductors of the core wires 111 and the ground wire 112 are selected as stranded tinned copper wires, which can make the wire more flexible and increase the bending resistance of the wire. The insulating layer of the core wire 111 is made of foamed PE material. Foamed PE has a smaller dielectric constant, and the core wire diameter can be made smaller on the premise of ensuring performance, so that the overall OD of the wire can be made smaller. Further, the twist pitch of the two core wires 111 is 12 - 14 mm. Preferably, the twist pitch is 13 mm. The small twist pitch design improves the bending resistance performance.
[0024] Further, the signal transmission line 10 further includes a pair of wires 14 and several single wires 13. The pair of wires 14 and several single wires 13 are located on both sides of the signal wire group 11. The pair of wires 14 and the single wires 13 can be electronic wires or spare wires.
[0025] Further, the power line 20 includes several electric wires 21 and an aluminum foil 22 wrapped around the periphery of the electric wires 21. The external aluminum foil increases the overall anti-interference performance of the wire and prevents the power line 20 from interfering with the signal transmission of the signal transmission line 10. Among them, the conductor of the electric wire 21 is made of stranded tinned copper wire, and the insulating layer is made of flame-retardant PVC material with a hardness of 70A, which can meet the requirements of a temperature resistance of 80°C and a voltage level of 300V, while ensuring the softness of the wire.
[0026] In summary, in the solution of the present application, by designing the signal transmission line and the power line, the signal transmission line is wrapped with a first outer covering layer, and the power line is wrapped with a second outer covering layer. A part of the outer peripheral surfaces of the first outer covering layer and the second outer covering layer are connected. After the first outer covering layer and the second outer covering layer are respectively wrapped around the signal transmission line and the power line, by connecting the first outer covering layer and the second outer covering layer into one body, the signal transmission line and the power line are relatively fixed and combined into one whole, improving the stress strength of the wire. At the same time, the wire will not be twisted during use and movement, and the overall design structure also makes the wire stress uniform and has better bending resistance performance.
[0027] The above-described embodiments do not constitute a limitation on the protection scope of the technical solution. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the above embodiments shall be included in the protection scope of the technical solution.
