Description

Technical Field

[0001] The utility model relates to the technical field of connecting wires, in particular to a connecting wire for an air inlet particle sensor. Background Art

[0002] The air inlet particle sensor connecting wire is a cable or line used to connect the air inlet particle sensor with the control system or other related equipment. The function of these connecting wires is to transmit the particle concentration data or other related information detected by the sensor to the control system for real-time monitoring, control or data analysis. The connecting wires are usually composed of multiple wires or cables, which are wrapped in a protective insulation layer to ensure stable electrical performance and mechanical strength even in harsh environments. One end of the connecting wire is connected to the sensor and the other end is connected to the control system or other related equipment. The air inlet particle sensor connecting wire is an important part of the sensor system. They are responsible for transmitting the data detected by the sensor to the control system.

[0003] A sensor connecting wire with the public number CN205752884U comprises a connecting wire (210), both ends of the connecting wire (210) are provided with wiring plugs (220), and one end of the connecting wire (210) is also provided with a number tube (250); at least one magnetic ring (230) is provided on the connecting wire (210), and the connecting wire (210) is wound around the magnetic ring (230) for at least one circle; a heat shrink sleeve (240) is provided on the connecting wire (210), and the heat shrink sleeve (240) simultaneously wraps the at least one magnetic ring (230). The utility model can better eliminate external high-frequency interference signals. In this scheme, the connecting wire may be damaged when exposed to a harsh environment (such as high temperature, high humidity, dust, corrosive gas, etc.) for a long time. For example, the insulation layer may age, harden, crack, resulting in electrical performance degradation or short circuit. Special tools or skills are required for installation and maintenance, which increases the cost of use. For this reason, we propose an air inlet particle sensor connecting wire.

The connecting column fixes the center of the rotating gear 6 and the center gear 7 to prevent the rotating gear 6 and the center gear 7 from moving.

[0028] Furthermore, the movable leaves 10 are arranged downward in a stepped manner from the inside to the outside to prevent the multiple movable leaves 10 from affecting each other when moving.

[0029] Furthermore, the movable leaf 10 is made of insulating, anti-skid, anti-scratch and anti-wear materials, and the movable leaf 10 clamps the cable 5 to prevent the insulation layer of the cable 5 from being damaged at the clamping position.

[0030] Furthermore, two ends of the movable gear 9 are movably connected to the inner wall of the left terminal 2 , and the movable gear 9 fixes the gear ring 8 . The movable gear 9 rotates with the gear ring 8 and will not affect the left terminal 2 .
