Description

Technical Field

[0001] This utility model relates to a cable, and more particularly to a high-speed differential signal cable for a robot vision sensor. Background Technology

[0002] In order to improve the efficiency and applicability of robots, various sensors, such as vision sensors, are usually installed when using them. In order to reduce signal transmission delay and external interference, dedicated signal cables are used to transmit vision signals. However, the bending resistance of existing signal cables is not ideal. For application scenarios where the position of vision sensors needs to change frequently, traditional signal cables are easily damaged and deformed irregularly after repeated bending, such as twisting and bending. This damage to the signal cables is difficult to repair, causing many inconveniences to signal transmission and highlighting the shortcomings of existing technology. Utility Model Content

[0003] The purpose of this invention is to provide a high-speed differential signal cable for a robot vision sensor to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-speed differential signal cable for a robot vision sensor includes a cable body, plugs, receiving grooves, raised pressure plates, extrusion protrusions, hexagonal nuts, and a helical spring. The cable body has plugs inserted into its front and rear sections with gaps, the plugs being symmetrically arranged. The opposite ends of the two plugs are hexagonal cylindrical, while adjacent ends are threaded cylindrical. Multiple receiving grooves radially penetrate the adjacent ends of the two plugs, and each receiving groove contains a flexible raised pressure plate. The raised pressure plate protrudes from the threaded cylindrical portion of the plug and has a gap with the receiving groove. Multiple extrusion protrusions are fixed to the end face of the raised pressure plate adjacent to the inner wall of the plug. The threaded cylindrical portions of the two plugs are coaxially threaded with hexagonal nuts, and both hexagonal nuts are fitted with a helical spring. The cable body is gap-inserted into the helical spring. The hexagonal nuts can extrude the raised pressure plates, causing them to bend and deform inwards towards the plug, thus extruding the cable body with the extrusion protrusions.

[0006] Based on the above technical solution, the regular hexagonal nut has a through slot and a bending groove is opened near the end face of the regular hexagonal cylindrical plug. The slot is parallel to the axial direction of the regular hexagonal nut, and the bending groove is perpendicular to the axial direction of the regular hexagonal nut. The bending groove is connected to the slot. The two ends of the helical spring can be inserted into the slot and the bending groove and bend accordingly. The end of the helical spring inserted in the bending groove can be clamped by the regular hexagonal cylindrical end face of the plug and the bending groove.

[0007] Based on the above technical solution, screw cylinders are fixed to the back-to-back ends of the two plugs. The screw cylinders are coaxially arranged with respect to the regular hexagonal cylindrical structure of the plugs. The screw cylinders are interlocked with the cable body. An annular pressure plate is fixed at the junction of the screw cylinders and the plugs. The annular pressure plate is coaxially arranged with respect to the screw cylinders. Rubber washers are inserted into the two screw cylinders respectively.

[0008] Based on the above technical solution, the helical spring is fitted with multiple ball bearings, which can rotate and move freely on the helical spring.

[0009] Compared with the prior art, the present invention has the following advantages: When the present invention is used, the hexagonal nut can squeeze the protruding pressure plate, so that the squeezed protrusion hugs the cable body, thereby restricting the position of the plug and limiting the extension and contraction state of the helical spring. When the cable body is bent, the elastic force of the helical spring can make the bending of the cable body more even and regular, thereby reducing the bending and twisting of the cable body, reducing the deformation and damage of the cable body, and improving the stability of the signal transmission of the cable body.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1-3As shown, a high-speed differential signal cable for a robot vision sensor includes a cable body 1, a plug 2, a receiving groove 3, a raised pressure plate 4, a compression protrusion 5, a regular hexagonal nut 6, and a helical spring 7. The cable body 1 has plugs 2 inserted into its front and rear sections, with the plugs 2 arranged symmetrically. The opposite ends of the plugs 2 are hexagonal cylindrical, while adjacent ends are threaded cylindrical. Multiple receiving grooves 3 radially penetrate the adjacent ends of the plugs 2, and each receiving groove 3 contains a flexible raised pressure plate 4. The protruding pressure plate 4 protrudes from the threaded cylindrical portion of the plug 2 and leaves a gap between it and the receiving groove 3. Multiple extrusion protrusions 5 are fixed on the end face of the protruding pressure plate 4 adjacent to the inner wall of the plug 2. The threaded cylindrical portions of the two plugs 2 are coaxially threaded together with a regular hexagonal nut 6. The two regular hexagonal nuts 6 are jointly installed with a helical spring 7. The cable body 1 is interposed in the helical spring 7. The regular hexagonal nut 6 can extrude the protrusion 5 pressure plate 4, causing it to bend and deform inward toward the plug 2, so that the extrusion protrusion 5 extrudes the cable body 1.

[0016] In use, the hexagonal nut 6 can be used to press the raised pressure plate 4, so that the pressing protrusion 5 hugs the cable body 1, thereby restricting the position of the plug 2 and limiting the extension and retraction of the helical spring 7. When the cable body 1 bends, the elastic force of the helical spring 7 can make the bending of the cable body 1 more even and regular, thereby reducing the bending and twisting of the cable body 1, reducing the deformation and damage of the cable body 1, and improving the stability of the signal transmission of the cable body 1.

[0017] The hexagonal nut 6 has a slot 8 through it, and a bending groove 9 is formed near the hexagonal cylindrical end face of the plug 2. The slot 8 is parallel to the axial direction of the hexagonal nut 6, and the bending groove 9 is perpendicular to the axial direction of the hexagonal nut 6. The bending groove 9 is connected to the slot 8. Both ends of the helical spring 7 can be inserted into the slot 8 and the bending groove 9 and bend accordingly. The end of the helical spring 7 inserted in the bending groove 9 can be clamped by the hexagonal cylindrical end face of the plug 2 and the bending groove 9.

[0018] Furthermore, with the plug 2 in the same position, the helical spring 7 can be appropriately cut using external tools, and then the helical spring 7 can be inserted into the slot 8 and the bending slot 9 to adjust its extension and retraction state. For example, when the bending degree of the cable body 1 in the usage environment is not high, the helical spring 7 in the retracted state can better protect the cable body 1 and reduce the damage caused by sharp objects. When the bending degree of the cable body 1 in the usage environment is high, the helical spring 7 in the stretched state can better protect the cable body 1 from bending and make its bending more uniform.

[0019] Screws 10 are fixed to the back-to-back ends of the two plugs 2. The screws 10 are coaxial with the hexagonal cylindrical structure of the plugs 2. The screws 10 are interlocked with the cable body 1. An annular pressure plate 11 is fixed at the junction of the screws 10 and the plugs 2. The annular pressure plate 11 is coaxial with the screws 10. Rubber washers 12 are inserted into the two screws 10 respectively.

[0020] Furthermore, a threaded hole matching the screw barrel 10 is provided at the connection position of the cable body 1. The screw barrel 10 is threadedly connected to the threaded hole to ensure the stability of the plug 2 and the cable body 1 relative to the robot. The rubber washer 12 can achieve the anti-loosening effect, thereby improving the stability of the plug 2 and the cable body 1 relative to the robot.

[0021] The helical spring 7 is fitted with a plurality of ball bearings 13, which are able to rotate and move freely on the helical spring 7.

[0022] Furthermore, the use of ball bearings 13 can reduce the mutual wear between the helical spring 7 and the cable body 1, while limiting the position of the cable body 1 relative to the helical spring 7, reducing the relative bending and scratching between the two, thereby further protecting the cable body 1.

[0023] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
