Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

The waterproof cover for the circuit breaker comprises two semicircular fixing plates 1, wherein a dovetail groove 9 which is communicated left and right is formed in each fixing plate 1, the dovetail groove 9 is wide in the front and narrow in the back, the dovetail groove 9 enables the circuit breaker to be installed, a clamping groove 14 of the circuit breaker corresponds to the dovetail groove 9 in the fixing plate 1, the circuit breaker is placed in the device, then the dovetail groove is buckled on a hanging rack, and rainwater is prevented from entering the clamping groove 14 of the circuit breaker.

Connect through the connecting frame 2 of quarter circular shape between two fixed plates 1, 2 lower extremes of connecting frame are equipped with weather shield 10, and the circuit breaker rear end contacts with weather shield 10 front end, and weather shield 10 makes circuit breaker and this device laminate more, improves the water-proof nature of this device.
