Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector for PIR sensors that is convenient and reliable for connection. Background Technology

[0002] A PIR (Passive Infrared) sensor is an electronic device used to detect infrared radiation. It is commonly used for motion detection and has wide applications in security monitoring, smart homes, and smart lighting. Currently available PIR sensor connectors, which offer convenient and reliable connections, mainly consist of an insulating body and conductive terminals. The insulating body is typically made of plastic, providing support and insulation, while the conductive terminals are mostly made of metal, used for electrical connection.

[0003] Current PIR sensor connectors on the market, while offering convenient and reliable connections, have several shortcomings. First, the connection reliability is insufficient: the existing connection method between the female connector and the PIR sensor pins is not robust enough. In daily use, even slight vibrations, shaking, or plugging / unplugging operations can cause poor contact between the pins and the female connector, affecting sensor signal transmission and leading to inaccurate detection or system malfunction. Second, conductivity is inadequate: some female connectors have improperly selected conductive terminal materials or surface treatments, resulting in high resistance and generating excessive heat during current transmission. This not only wastes energy but may also affect sensor performance and lifespan. Finally, installation is inconvenient: the traditional female connector design requires precise positioning and complex operations when mounting it onto a circuit board, increasing production difficulty and cost, and reducing production efficiency.
