This invention discloses an anti-theft alarm
fastener. By integrating a position detection module, a control module, and an alarm module into the male and female buckles of an existing magnetic
fastener, it achieves real-time monitoring of the
fastener's connection status and automatic alarm functions upon unauthorized separation. The control module, with its function selection button, allows the fastener to flexibly switch between at least two operating
modes: alarm function off or on. This greatly improves the product's practicality and applicability, meeting diverse
user needs in different situations. The position detection module uses a magnetic trigger and a Hall sensor element to form a non-
contact position detection module, avoiding reliability issues caused by contact oxidation, wear, or poor contact in traditional mechanical switches. Furthermore, the
mating structure of the mounting groove and positioning recess improves the accuracy and consistency of detection, effectively avoiding misjudgments or missed alarms due to positional misalignment.
