Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to an industrial control wire harness with strong tensile strength. Background Art

[0002] An industrial control wiring harness is a group of metal wires and cables tied together to carry signals and power between devices. It consists of an insulating sheath, terminals, wires, and insulating wrapping materials. It can stably and safely transmit electronic signals or power from one end of a system or device to the other end of the system or device. Industrial control wiring harnesses are widely used in industrial automation, robotic intelligent control systems, CNC machine tools, and other fields to ensure the normal operation and control of equipment.

[0003] The current industrial control wiring harnesses are used in complex environments, making them susceptible to collision and pulling, which can damage the wiring harnesses and render them unusable, reducing their service life. To this end, we propose an industrial control wiring harness with strong tensile strength. Utility Model Content

[0004] The purpose of the utility model is to provide an industrial control wiring harness with strong tensile resistance, which has the advantage of being able to improve the tensile resistance of the industrial control wiring harness to prevent it from being damaged when pulled or collided, thereby extending the service life of the industrial control wiring harness. It solves the problem that the current industrial control wiring harness is used in a relatively complex site, which makes it easy to be collided and pulled, resulting in damage to the wiring harness, making the wiring harness unusable and reducing the service life of the wiring harness.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an industrial control wiring harness with strong tensile resistance, comprising a plastic-steel wire, an electric wire and a terminal, wherein the outer surface of the plastic-steel wire is provided with a plurality of electric wires in a circular array at equal intervals, and the electric wires are spirally wound around the outer surface of the plastic-steel wire, the end of the electric wire is electrically connected to the terminal, a connecting frame is installed on the outer surface of the terminal, and the end of the plastic-steel wire is connected to the connecting frame.

[0006] Preferably, a protective rubber sleeve is sleeved on the outer surface of the electric wire, and the protective rubber sleeve protects the electric wire.

[0007] Preferably, a filling layer is provided in the gap between the wire and the protective rubber sleeve, and the filling layer can fill the gap between the wire and the protective rubber sleeve to improve the stability of the wire inside the protective rubber sleeve and make the structure inside the protective rubber sleeve more stable.

[0008] Preferably, the outer surface of the protective rubber sleeve is provided with a wear-resistant coating, which can improve the surface wear resistance of the protective rubber sleeve to prevent the protective rubber sleeve from being easily damaged due to wear, thereby extending the service life of the protective rubber sleeve and providing better protection for the wires.

[0009] Preferably, the interior of the plastic-steel wire is a hollow structure. The plastic-steel wire with a hollow structure is lighter, which reduces the overall weight of the industrial control wiring harness and also saves material costs.

[0010] Preferably, an annular groove is provided on the outer surface of the plastic-steel wire near the end position, a bayonet is provided on the outer surface of the connecting frame, a socket is provided on the front surface of the connecting frame, and the socket and the bayonet are connected. When the plastic-steel wire and the terminal are connected, the annular groove on the plastic-steel wire is inserted from the socket into the bayonet to complete the connection between the plastic-steel wire and the terminal, which facilitates the connection between the terminal and the plastic-steel wire.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The utility model achieves the effect of improving the tensile strength of the industrial control wiring harness by arranging electric wires, plastic-steel wires and terminals to prevent it from being damaged when pulled or collided, thereby extending the service life of the industrial control wiring harness. The electric wires and plastic-steel wires constitute the main structure of the industrial control wiring harness, and the industrial control wiring harness uses a light-weight and high-strength plastic-steel wire as the core, and the wires used for power supply and communication are spirally wound on the outer surface of the plastic-steel wire. When the industrial control wiring harness is collided and pulled, the plastic-steel wire can provide high-strength tensile strength. At the same time, the spirally wound wire has a certain deformation resistance and will not be damaged, which greatly improves the overall tensile strength of the industrial control wiring harness.

[0013] 2. The utility model can improve the surface wear resistance of the protective rubber sleeve by providing a wear-resistant coating to prevent the protective rubber sleeve from being easily damaged due to wear, thereby extending the service life of the protective rubber sleeve and providing better protection for the wires.

[0014] 3. The present invention can fill the gap between the wire and the protective rubber sleeve by providing a filling layer, thereby improving the stability of the wire inside the protective rubber sleeve and making the structure inside the protective rubber sleeve more stable.

[0015] 4. The utility model achieves the effect of facilitating the connection between the plastic-steel wire and the terminal by setting the annular groove, the socket and the bayonet. When the plastic-steel wire and the terminal are connected, the annular groove on the plastic-steel wire is inserted from the socket into the bayonet to complete the connection between the plastic-steel wire and the terminal.

The electric wires 2 and the plastic-steel wire 1 constitute the main structure of the industrial control wiring harness. The end of the electric wire 2 is electrically connected to the terminal 5, and the electric wire 2 is electrically connected to the equipment through the terminal 5. A connecting frame 4 is installed on the outer surface of the terminal 5, and the end of the plastic-steel wire 1 is connected to the connecting frame 4. The interior of the plastic-steel wire 1 is a hollow structure. The hollow structure of the plastic-steel wire 1 is lighter, which reduces the overall weight of the industrial control wiring harness and also saves material costs.

When the industrial control wiring harness is subjected to collision and pulling, the plastic-steel wire 1 can provide high-strength tensile resistance. At the same time, the spirally wound electric wire 2 has a certain ability to resist deformation and will not be damaged, which greatly improves the overall tensile resistance of the industrial control wiring harness and extends its service life.

[0027] In this embodiment, the wear-resistant coating 6 can improve the surface wear resistance of the protective rubber sleeve 3 to prevent the protective rubber sleeve 3 from being easily damaged due to wear, thereby extending the service life of the protective rubber sleeve 3 and providing better protection for the wire 2.
