Description

Technical Field

[0001] This utility model relates to the field of connecting wires, and in particular to a connecting wire for robots. Background Technology

[0002] A robot is an intelligent machine capable of semi-autonomous or fully autonomous operation. Through programming and automatic control, robots can perform tasks such as manual labor or movement. They possess fundamental characteristics such as perception, decision-making, and execution, and can assist or even replace humans in dangerous, arduous, and complex tasks, improving work efficiency and quality, serving human life, and expanding or extending the scope of human activities and capabilities.

[0003] To make robots more intelligent and functional, developers incorporate numerous internal modules connected by cables. To avoid a cluttered internal wiring layout that hinders maintenance, manufacturers often integrate these cables, allowing connection to multiple modules. However, the frequent movement of the robot causes these cables to deform and shift position. The integrated cables, with their multiple components and sheathing, create resistance to this deformation, affecting the robot's movement and reducing its agility. Therefore, a solution is needed to address these issues. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a connecting cable for robots that can effectively solve the problem that the existing connecting cables, due to the presence of multiple wires and outer sheaths, cause resistance to the deformation of the connecting cable, affecting the robot's movement and thus reducing the robot's movement sensitivity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A connecting cable for robots includes a wire harness, a connector body, and an outer sleeve. One end of the wire harness is connected and fixed with a first terminal and a plurality of second terminals, and the other end of the wire harness is connected and fixed with a plurality of third terminals. The connector body is disposed at the other end of the wire harness and includes an inner mold body and an outer mold body. The inner mold body includes an integrally formed body portion and a plug portion. The integrally formed design makes the product more consistent and saves molding time and disassembly and assembly time of semi-finished products, thereby improving production efficiency. The plug portion has a plug cavity into which the aforementioned plurality of third terminals extend. The outer mold body covers the inner mold body. The outer sleeve includes a first tube body and a second tube body, both of which are sleeved on the wire harness. A first movable groove is formed between the first tube body and the second tube body, and a second movable groove is formed between the second tube body and the outer mold body.

[0007] As a preferred embodiment, the first terminal is provided with a fixing hole, and the design of the fixing hole makes the first terminal and the external terminal more securely and reliably connected together.

[0008] As a preferred embodiment, each of the plurality of second terminals has a contact portion, and a limiting portion is torn into each contact portion.

[0009] As a preferred embodiment, the plurality of second terminals are all connected and fixed to one end of the wire harness by riveting, so that the second terminals and the wire harness are more firmly and reliably connected together.

[0010] As a preferred embodiment, a limiting groove is provided on the plug-in part, which extends to the left and right to effectively prevent the plug-in part from rotating after it is plugged in.

[0011] As a preferred embodiment, the third terminal includes an integrally formed main body and a connecting part. The main body is embedded in the main body and has a boss with knurled patterns. This design allows the third terminal to fit more firmly and reliably with the main body. The connecting part is located in the insertion cavity.

[0012] As a preferred embodiment, the inner mold body is made of PA610 material, and the outer mold body is made of TPE material.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0014] By designing the outer tube as a two-piece structure, the outer tube includes a first tube body and a second tube body, both of which are fitted onto the wire harness. Furthermore, a first movable groove is formed between the first tube body and the second tube body, and a second movable groove is formed between the second tube body and the outer mold body. The presence of the first and second movable grooves greatly reduces the resistance of the outer tube when the connecting wire undergoes bending deformation, thus not affecting the robot's movement and improving the robot's agility.

[0033] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a wire harness 10, a connector body 20, and an outer sleeve 30.

[0034] One end of the wire harness 10 is connected and fixed with a first terminal 11 and a plurality of second terminals 12, and the other end of the wire harness 10 is connected and fixed with a plurality of third terminals 13. In this embodiment, the first terminal 11 is provided with a fixing hole 111, and the design of the fixing hole 111 makes the first terminal 11 more firmly and reliably connected to the external terminal. Each of the plurality of second terminals 12 has a contact portion 121, and a limiting portion 122 is torn on each contact portion 121. The plurality of second terminals 12 are all connected and fixed to one end of the wire harness 10 by riveting, so that the second terminals 12 and the wire harness 10 are more firmly and reliably connected. In addition, the third terminal 13 includes an integrally formed main body portion 131 and a connecting portion 132.

[0035] The connector body 20 is disposed at the other end of the wire harness 10. The connector body 20 includes an inner mold body 21 and an outer mold body 22. The inner mold body 21 includes an integrally formed body portion 211 and a plug portion 212. The integrally formed design makes the product more consistent and saves molding time and disassembly and assembly time of semi-finished products, thereby improving production efficiency. The plug portion 212 has a plug cavity 213, and the aforementioned plurality of third terminals 13 all extend into the plug cavity 213. The outer mold body 22 covers the inner mold body 21. In this embodiment... In the design, the main body 131 is embedded in the body 211, and the main body 131 is provided with a boss 133, which is provided with knurled 134. This design can make the third terminal 13 fit more firmly and reliably with the body 211. The connecting part 132 is located in the insertion cavity 213. The insertion part 212 is provided with a limiting groove 214, which extends to the left and right to effectively prevent the insertion part 212 from rotating after it is inserted into place. The inner mold body 21 is made of PA610 material, and the outer mold body 22 is made of TPE material.

[0036] The outer sleeve 30 includes a first tube body 31 and a second tube body 32, both of which are sleeved on the wire harness 10. A first movable groove 301 is formed between the first tube body 31 and the second tube body 32, and a second movable groove 302 is formed between the second tube body 32 and the outer mold body 22.

[0037] The key design feature of this invention is that the outer sleeve is designed as a two-piece structure, comprising a first tube and a second tube. Both the first and second tubes are fitted onto the wire harness. A first movable groove is formed between the first and second tubes, and a second movable groove is formed between the second tube and the outer mold body. The presence of the first and second movable grooves greatly reduces the resistance of the outer sleeve when the connecting wire is bent or deformed, thus not affecting the robot's movement and improving the robot's agility.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
