The invention discloses a
wireless anti-theft alarm terminal for a well lid. The
wireless anti-theft alarm terminal comprises an outer box, wherein the outer box is composed of an upper lid and a lower lid, the upper lid is helically connected with the lower lid so as to well play a water proof and
moisture proof function, a fixed connecting structure is arranged in the upper lid of the outer box, the fixed connecting structure is respectively connected and fixed with a power supply switch and a circuit board through screws, a power supply groove is formed in the upper lid of the outer box, a power supply is installed in the power supply groove, the power supply is connected with the power supply switch through an
electric wire, the power supply switch is connected with the circuit board through the
electric wire, the power supply switch is a gravity conductive ball sliding rail switch, and a
wireless anti-theft alarm terminal (which is arranged adjacent to the circuit board) of the well lid can automatically organize a network, the circuit board is connected with an antenna through the
electric wire, a connecting device of an external power supply is arranged in the upper lid, and a
metal device connected with the antenna is arranged in the upper lid, so that the
power consumption of the gravity conductive ball sliding rail switch is low, the use is safe, the open state of the well lid can be automatically monitored, and the position of the antenna can be automatically selected according to external environments, so that a
signal is good and the antenna can be normally used under severe natural environments.
