The invention provides an anti-wire fracture alarm device. The device comprises a mounting plate, a copper wire guiding device and a triggering device; the copper wire guiding device and the triggering device are both installed on the surface of the mounting plate; a copper wire for making a coil penetrates through the triggering device through the guide of the copper wire guiding device; and thefracture of the copper wire triggers the triggering device. According to the device of the invention, the guiding device is adopted to guide the copper wire for making the coil to penetrate through the triggering device; when the copper wire is fractured, the triggering device is triggered, so that a motor for making the coil stops operating, and meanwhile, an alarm lamp corresponding to the serial number of the triggering device is turned on, and therefore, the fracture of the copper wire can be found immediately during coil manufacturing, and the serial number of the fractured copper wire can be known conveniently through the serial number of the turned-on alarm lamp, and at the same time, the working motor stops rotating, so that a condition that a worker does not pay attention to the turning on of the alarm lamp and continues to produce an unqualified coil can be avoided.
