[0001] This application relates to the technical field of cables, and particularly to a temperature-sensing control cable harness. Background Art

[0002] Semiconductor equipment is the core of semiconductor manufacturing. For semiconductor devices, temperature is a key operating parameter. Excessive temperature may lead to a decline in device performance or even damage. Therefore, in order to ensure that the power supply is automatically cut off when the device reaches a preset temperature threshold to prevent damage caused by overheating, a control cable harness needs to be designed and applied to the device power supply to enable the device to automatically cut off the power when the preset temperature threshold is reached. Utility Model Content

[0004] Preferably, the wire diameter of the phosphor bronze alloy conductor is 0.05 - 0.06 mm.

[0013] 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. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0014] Embodiment

[0015] In order to solve the above technical problems, this embodiment provides a temperature sensing control wire harness, as Figure 1-2 shown, including a temperature sensing wire 10, several power wires 20 wound around the temperature sensing wire 10, and a shielding layer 30, a braided layer 40, and an outer sheath layer 50 sequentially coated on the outer periphery. The temperature sensing wire 10 includes two twisted core wires 11, an aluminum foil layer 12 and a polyester tape layer 13 coating the core wires 11. The core wires 11 include several stranded phosphor bronze alloy conductors 111 and a semiconductor material layer 112 coating the phosphor bronze alloy conductors 111. The power wires 20 are used to provide power, and the core wires 11 are used to transmit signals. Among them, the semiconductor material layer 112 is in a conductor state when the temperature is higher than 80 °C, causing the two signal core wires 11 to be short-circuited, and the signal is cut off, so that the control circuit takes power-off protection measures to achieve the purpose of protecting the equipment. When the temperature is lower than 80 °C, the semiconductor material layer 112 returns to an insulating state after a period of time, and the core wire conductors are not short-circuited, and the equipment operates normally.

[0016] Among them, the semiconductor material layer 112 can adopt the PVC semiconductor material of Mitsubishi in Japan, and its conductivity changes due to temperature changes.

[0017] Specifically, the conductor of the core wire 11 is made of a category 5 soft phosphor bronze alloy. The wire diameter of the phosphor bronze alloy conductor 111 is 0.05 - 0.06 mm. Preferably, the wire diameter is 0.06 mm. The phosphor bronze alloy conductor 111 is stranded along the S direction, and the stranding pitch is 8 - 10 mm, with a stranding pitch of 10 mm. The S-direction stranding ensures the stability of the conductor structure. At the same time, the conductor has a round appearance, and the entire wire exhibits good flexibility and high tensile strength.

[0018] In the above solution, the temperature-sensing wire 10 includes two twisted core wires 11, an aluminum foil layer 12 and a polyester tape layer 13 covering the core wires 11. Among them, the aluminum foil layer 12 covers the two core wires 11, and the polyester tape layer 13 is wound along the S direction. The thickness of the polyester tape layer 13 is 0.25 - 0.3 mm. The polyester tape layer 13 isolates the core wires 11 from the shielding layer 30 to prevent short circuits, and the aluminum foil layer 12 prevents the current of the power wire 20 from interfering with the signal transmission of the core wires 11.

[0019] Furthermore, the shielding layer 30 is composed of aluminum foil and a mylar tape, which plays a shielding role for the overall cable to ensure that signal transmission is not interfered with.

[0020] Furthermore, in the above solution, by designing the control wire harness with the above structure, when the temperature-sensing wire 10 is damaged, the temperature-sensing wire 10 can be separately drawn out, and then the temperature-sensing wire 10 can be separately replaced, while retaining other core wires for continued use, achieving recyclability.

[0021] In the above solution, the braided layer 40 is woven from copper foil wires and tinned copper wires, and the ratio of the number of copper foil wires to tinned copper wires is 1∶2. The braided layer 40 with the above structure can ensure the softness of the wire, improve the flexibility, and at the same time increase the torsional and bending properties of the wire, improving the durability.

[0022] Furthermore, the outer sheath layer 50 is made of polymer PVC and is extruded using a semi-extrusion tube to ensure that the outer skin of the wire does not stick, and to ensure less stress between the outer sheath and the semi-finished product during torsion. After testing, there is no impact on the outer sheath after 10,000 times of torsion at -40°C, 360° / min - 1080° / min.

[0023] In summary, in the solution of the present application, several power lines are wound around the outer periphery of the temperature-sensing wire, and a shielding layer, a braided layer and an outer sheath layer are sequentially coated on the outer periphery. The temperature-sensing wire includes two twisted core wires, an aluminum foil layer and a polyester tape layer coating the core wires. The core wire includes several stranded phosphor bronze alloy conductors and a semiconductor material layer coating the phosphor bronze alloy conductors. Among them, the semiconductor material layer is in a conductor state when the temperature is higher than the preset value, so that the two signal core wires are short-circuited, thereby automatically taking power-off protection measures for the equipment to achieve the purpose of protecting the equipment. When the temperature is lower than the preset value, the semiconductor material layer returns to an insulating state after a period of time, and the two core wires are not short-circuited, and the equipment operates normally, thereby achieving the purpose of protecting the equipment according to the temperature and improving the safety of the equipment.

[0024] The above-described embodiments do not limit the protection scope of the technical solution. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the above embodiments shall be included in the protection scope of the technical solution.
