Description

Technical Field

[0001] This utility model relates to the field of temperature sensing technology, and in particular to a temperature sensor with a threaded bullet head. Background Technology

[0002] Temperature sensors, as core sensing elements that convert physical quantities of temperature into measurable electrical signals, play an irreplaceable role in industrial production, automotive electronics, smart homes, medical equipment, and many other fields. Their measurement accuracy, ease of installation, and environmental adaptability directly determine the operating efficiency, safety performance, and control precision of related systems. In industrial settings, they are used to monitor the temperature of production equipment and the temperature of media inside reaction vessels to ensure stable production processes. In the automotive electronics field, they are required to monitor engine coolant temperature, transmission oil temperature, and the temperature of critical components in real time, providing data support for vehicle power control and safety protection. In smart homes, they can adjust the operating status of air conditioners, water heaters, and other home appliances to improve living comfort. In medical equipment, they are an important tool for accurately monitoring human body temperature and the temperature of drug storage environments.

[0003] Currently, sensors commonly suffer from a core flaw in practical applications: fixed plug angles and orientations. This design limitation is particularly pronounced in industrial equipment, automotive electronics, and other complex installation scenarios. When sensors need to adapt to confined spaces or special layout requirements, fixed-angle plugs often lead to excessive cable bending, increasing signal transmission loss and potentially causing cable aging and cracking due to long-term stress. Furthermore, they cannot flexibly match the interface orientations of multiple devices, significantly reducing installation compatibility. To address this issue, the industry currently primarily achieves angle adaptation by adjusting the socket, compensating for plug angle deviations through the socket's structural design. However, this solution still has shortcomings. The compatibility of adjustable sockets is limited by differences in industry standards; for example, different specifications for interface parameters may lead to incompatibility between cross-brand products, and some adjustment mechanisms have additional requirements for installation space.

In addition, the outer wall of the threaded head 16 is provided with an external thread 19.

[0039] Working principle: When it is necessary to adjust the angle and direction of the plug 13, the hollow tube 3 can be rotated to make the hollow tube 3 rotate on the inner wall of the outer shell 4, thereby adjusting the angle of the plug 13. When the direction needs to be adjusted, the rotating shaft 3 8 rotates in the holes 2 7 and 3 10, thereby driving the connecting rod 2 11 and the connecting wire 12 to rotate, so that the plug 13 rotates accordingly, thereby allowing the direction of the plug 13 to be adjusted. Through the above, the angle and direction of the plug 13 are finally adjusted.

[0040] After the connecting shell 14 is connected to the wire 1, it can be further reinforced by the reinforcement mechanism 2. First, C-shaped plate 1 201 and C-shaped plate 203 are wrapped around the outer wall of the connecting shell 14. Then, with the rotating shaft 206 as the axis, the connecting rod 1 207 and the threaded rod 209 are inserted into the connecting block 210. Then, the nut 208 is turned to fix it. Finally, the reinforcement mechanism 2 can fix the connecting shell 14 and the wire 1.
