Description

Technical Field

[0001] This utility model relates to the field of electrical junction box technology, specifically an electrical junction box with an anti-tamper alarm device. Background Technology

[0002] Electrical junction boxes are an important component of power systems, mainly used to introduce power from the power source and distribute it to various electrical devices or circuits. They generally consist of a casing, internal wiring, switches, and protective devices, serving the functions of circuit protection, equipment connection, and distribution. To prevent theft of electrical appliances inside the junction box, alarm devices are now installed inside to improve its security.

[0003] Chinese patent discloses an electrical junction box with an anti-tamper alarm device (authorization announcement number CN217563247U). When the electrical junction box is placed in the external environment and is easily affected by rain, thus changing the humidity inside the electrical junction box, the humidity sensor can monitor the humidity inside the electrical junction box. When the humidity exceeds the standard, an abnormal signal is issued to remind maintenance personnel to carry out timely inspection and avoid the internal electrical equipment from being affected by moisture.

[0004] However, most existing electrical junction boxes use alarms implemented through alarms, infrared receivers, and infrared transmitters. This means the alarm, located inside the junction box, is not properly protected, and can easily be deactivated by opening the box, thus reducing security. For example, the aforementioned comparative document uses an alarm, infrared receiver, and infrared transmitter. In practical applications, when using these components, thieves can easily shut down the alarm after opening the junction box, preventing continuous alarm activation and compromising security. Therefore, those skilled in the art provide an electrical junction box with an anti-tamper alarm device to address the problems mentioned in the background section. Utility Model Content
