Abstract
The invention discloses an ultraviolet-ray detector. The ultraviolet-ray detector includes an upper casing, a lower casing, a transparent face casing, a circuit board and a key switch. A light sensor and a light-intensity indicator are arranged on the circuit board. The transparent face casing is connected with the upper casing and the lower casing. The transparent face casing is located above the light-intensity indicator. The inner surface of the upper casing is provided with a circuit board fixing device. A circuit board clamping device is arranged on the lower casing. The circuit board fixing device cooperates with the circuit board clamping device to fix the circuit board. The circuit board fixing device is separable with the circuit board clamping device. In the ultraviolet-ray detector, because the circuit board fixing device cooperates with the circuit board clamping device to fix the circuit board and the circuit board fixing device is separable with the circuit board clamping device, disassembly is convenient when a fault happens to the circuit board so that maintenance is significantly convenient.
