Description

Technical Field

[0001] This utility model relates to the field of connecting wire technology, and in particular to a highly wear-resistant connecting wire. Background Technology

[0002] Connecting wires generally refer to the conductors or cables used to connect different components in electronic devices, electrical equipment, or circuits. The materials and types of connecting wires vary depending on the specific application and requirements. High abrasion-resistant connecting wires are a specially designed type of connecting wire with high abrasion resistance, enabling them to operate stably for extended periods under harsh environmental conditions.

[0003] For example, CN216528065U discloses a corrosion-resistant and wear-resistant high-efficiency transmission cable, comprising a wear-resistant layer, an anti-corrosion layer bonded to the inner wall of the wear-resistant layer, an insulation layer bonded to the inner cavity of the anti-corrosion layer, glass fiber bonded to the inner wall of the insulation layer, a battery core disposed within the inner cavity of the glass fiber, a neoprene rubber layer in the wear-resistant layer, a nitrile rubber layer bonded to the inner cavity of the neoprene rubber layer, and a polytetrafluoroethylene (PTFE) film layer. This invention, through the combined use of the neoprene rubber layer, nitrile rubber layer, PTFE film layer, and epoxy phenolic layer, solves the problem that existing cables typically lack corrosion resistance, making them prone to damage during use and affecting their usability. Furthermore, their poor wear resistance can cause inconvenience to users.

[0004] Based on the search of the aforementioned patents and the findings of existing connecting wires, it is discovered that existing connecting wires generally lack sufficient wear resistance during use and lack an early warning mechanism when wear approaches or reaches the working core, which can easily lead to unexpected malfunctions or failures. To address the problems existing in the prior art, this application proposes a highly wear-resistant connecting wire. Utility Model Content

[0005] The purpose of this invention is to provide a highly wear-resistant connecting wire. The outer layer, made of a rubber-coated anti-scratch layer, provides excellent wear resistance. The middle layer, made of a second rubber layer, ensures the wire is not easily damaged during bending and stretching. The inner layer, made of a second silicone layer, provides cushioning. The combined effect of these three layers significantly improves the wire's wear resistance. The conductive detection wire connects to the circuit breaker alarm circuit via metal contacts inside the male and female connectors. When the conductive detection wire wears and breaks, the circuit breaker alarm circuit detects the breakage and issues a warning, reminding staff to maintain the line promptly and prevent further wear to the conductive core, thus avoiding unexpected equipment malfunctions. This addresses the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high wear-resistant connector specifically includes: an anti-wear layer, with a male and a female connector fixed at both ends of the anti-wear layer, a soft PVC layer wrapped inside the anti-wear layer, a conductive detection wire spirally embedded inside the soft PVC layer, the conductive detection wire being electrically connected to the metal contacts inside the male and female connectors, an insulating layer wrapped inside the soft PVC layer, a plurality of conductive cells evenly distributed inside the insulating layer, an insulating layer wrapped outside the conductive cells, and reinforcing ribs provided between the insulating layers and at the axial position of the insulating layer.

[0011] In a preferred embodiment of the high wear-resistant connecting wire provided by this utility model, the reinforcing rib includes a steel wire, and the outer side of the steel wire is wrapped with a PVC coating layer.

[0012] In a preferred embodiment of the high wear-resistant connecting wire provided by this utility model, talc powder is filled between the isolation layer, the PVC wrapping layer and the first rubber layer.

[0013] In a preferred embodiment of the high wear-resistant connecting wire provided by this utility model, multiple rigid PVC wear-resistant rings are evenly distributed and fixed on the outer side of the anti-scratch layer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The outer layer, made of a tough, scratch-resistant material, provides excellent abrasion resistance. The middle layer, made of a second rubber layer, ensures that the wire is not easily damaged when bent and stretched. The inner layer, made of a second silicone layer, provides cushioning. The combined effect of these three layers significantly improves the abrasion resistance of the wire.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please refer to Figure 1-6 A high-wear-resistant connector includes an anti-wear layer 1, with a male connector 14 and a female connector 15 fixed at both ends. The anti-wear layer 1 is internally encased in a soft PVC layer 2, within which a conductive detection wire 4 is spirally embedded. Embedding the conductive detection wire 4 within the soft PVC layer 2 prevents it from rusting due to contact with air, thus avoiding breakage and improving the stability of the cable. The soft PVC layer 2 also fills the gap between an insulating layer 3 and the anti-wear layer 1, maximizing the internal space of the cable and enhancing its wear resistance. The conductive detection wire 4 is electrically connected to the metal contacts inside the male connector 14 and the female connector 15. An insulating layer 3 is also encased within the soft PVC layer 2. The insulating layer 3 is used to isolate the soft PVC layer 2 and the insulation layer 17. Several conductive cores 5 are evenly distributed inside the insulating layer 3. The conductive cores 5 are electrically connected to the metal contacts inside the male connector 14 and the female connector 15. The conductive cores 5 are wrapped with the insulation layer 17. A reinforcing rib 8 is provided between the several insulation layers 17 and at the axial position of the insulating layer 3. The reinforcing rib 8 is used to improve the overall bending and tensile strength of the wire. Specifically, the conductive detection wire 4 is connected to the circuit breaker alarm circuit through the metal contacts inside the male connector 14 and the female connector 15. When the conductive detection wire 4 is worn and broken, the circuit breaker alarm circuit detects that the conductive detection wire 4 is broken, thereby issuing an early warning and reminding the staff to maintain the line in time to avoid further wear to the conductive cores 5, which could lead to unexpected equipment failure.

[0029] The anti-wear layer 1 includes an outermost tough rubber anti-scratch layer 9, a second rubber layer 10 wrapped inside the tough rubber anti-scratch layer 9, and a second silicone layer 11 wrapped inside the second rubber layer 10. Specifically, the tough rubber anti-scratch layer 9 has good anti-aging properties and high hardness, which can effectively resist external wear and cutting, and can provide good anti-wear performance for the wire on the outermost side. The second rubber layer 10 has a certain degree of elasticity and flexibility, making the wire less prone to damage when bending and stretching. The second silicone layer 11 has softness and good elasticity, which can play a buffering role, absorb external impact and vibration, and reduce the risk of damage to the connecting wire during use. The outer layer is provided with excellent wear resistance by the tough rubber anti-scratch layer 9, the middle layer is provided with the second rubber layer 10 to ensure that the wire is not easily damaged when bending and stretching, and the inner layer is provided with the second silicone layer 11 to provide a buffering role. Under the combined action of the three, the wear resistance of the wire can be significantly improved.

[0030] The conductive detection line 4 is made of copper. When the length of the line is long, copper with lower internal resistance can be used instead to improve the stability of the circuit breaker alarm circuit detection. Other materials such as iron and aluminum can also be used.

[0031] The insulating layer 17 includes a first silicone layer 6 and a first rubber layer 7. The first silicone layer 6 is wrapped around the outside of the conductive core 5, and the first rubber layer 7 is wrapped around the outside of the first silicone layer 6. Specifically, the first silicone layer 6 has soft and high temperature resistant properties, and the first rubber layer 7 has a certain degree of flexibility, so that the insulating layer 17 can have a certain degree of wear resistance while ensuring its softness and high temperature resistance, thereby improving the service life of the wire.

[0032] The reinforcing rib 8 includes a steel wire 12, the outside of which is wrapped with a PVC wrapping layer 13. The PVC wrapping layer 13 is used to prevent the steel wire 12 from directly contacting the insulation layer 17, and to prevent the steel wire 12 from causing wear to the insulation layer 17 during use.

[0033] Talc powder is filled between the isolation layer 3, the PVC wrapping layer 13 and the first rubber layer 7. During the use of the wire, the talc powder is used to lubricate the space between the isolation layer 3, the PVC wrapping layer 13 and the first rubber layer 7, thereby improving the service life and flexibility of the wire.

[0034] Multiple hard PVC anti-wear rings 16 are evenly distributed and fixed on the outer side of the toughness anti-scratch layer 9. The raised hard PVC anti-wear rings 16 can reduce the wear generated by the toughness anti-scratch layer 9 to a certain extent and improve the wear resistance of the wire.

[0035] The usage process of the high wear-resistant connecting wire provided by this utility model is as follows:

[0036] Technical Principle: The reinforcing rib 8 enhances the overall bending and tensile strength of the wire. Specifically, the conductive detection wire 4 connects to the conductor via metal contacts inside the male connector 14 and female connector 15. When the conductive detection wire 4 wears down and breaks, the circuit breaker alarm detects the breakage and issues a warning, reminding staff to maintain the line promptly to prevent further wear to the conductive core 5 and potential equipment malfunction. The anti-scratch layer 9 has good anti-aging properties and high hardness, effectively resisting external wear and cutting. The outer layer provides good abrasion resistance for the wire, the second rubber layer 10 has a certain degree of elasticity and flexibility, making the wire less prone to damage when bent and stretched, the second silicone layer 11 is soft and has good elasticity, which can play a buffering role, absorb external impact and vibration, and reduce the risk of damage to the connecting wire during use. The outer layer is provided with excellent abrasion resistance by the tough rubber anti-scratch layer 9, the middle layer is provided with the second rubber layer 10 to ensure that the wire is not easily damaged when bent and stretched, and the inner layer is provided with the second silicone layer 11 to provide a buffering role. With the combined effect of the three, the abrasion resistance of the wire can be significantly improved.

[0037] In this embodiment, the principle of the circuit breaker alarm circuit is as follows: Figure 6 As shown, the positive terminal of the 5V DC power supply is connected to a 100K resistor R1 and the emitter of an 8550 transistor Q2. R1 is connected to the base of the 8550 transistor Q2, and the collector of Q1 is connected to the base of Q2. The VCC terminal of the buzzer BL is connected in sequence to a 1K resistor R2, a 104 SMD capacitor C, and a trigger wire (i.e., the conductivity detection line 4 in this embodiment) to the negative terminal of the 5V DC power supply. The GND terminal of the buzzer BL is also connected to the negative terminal of the 5V DC power supply. The rear end of R1 and the front end of C are shorted. The emitter of Q1 is connected to the GND terminal of the buzzer BL, and the collector of Q2 is connected to the VCC terminal of the buzzer BL. The trigger wire grounds both the base and emitter of Q2, stopping the circuit. When the trigger wire (i.e., the conductivity detection line 4 in this embodiment) is disconnected, the circuit starts working, and the buzzer BL sounds an alarm. This provides an early warning, reminding staff to maintain the circuit in a timely manner.

[0038] Of course, in addition to the circuit breakers listed above, existing circuit breakers can also be used, which will not be discussed in detail here.

[0039] The parts of this utility model not described are existing technologies.
