The ejector pin block is in the arc spout of drain pan, epitheca to the assembly of ejector pin and drain pan, epitheca is more convenient, and can guarantee that the ejector pin can reliably move, is favorable to improving this backup protector's operational reliability.

Particularly, the drain pan in be provided with the storage tank with micro-gap switch looks adaptation, micro-gap switch set up in the storage tank, the storage tank in be provided with two locating levers, micro-gap switch on be provided with the locating hole, the locating lever alternate in the locating hole, and constitute drain pan and micro-gap switch's joint cooperation, the epitheca on correspond micro-gap switch department and be provided with the stopper, the stopper contradict on micro-gap switch, and constitute epitheca and micro-gap switch's spacing cooperation. The micro switch is clamped between the bottom shell and the upper shell, so that the assembling efficiency of the micro switch, the bottom shell and the upper shell is facilitated, and the assembling efficiency of the backup protector is improved.

Particularly, the bottom shell and the upper shell are respectively provided with a clamping groove corresponding to the signal terminals, and the clamping grooves of the bottom shell and the upper shell are respectively clamped on two sides of the signal terminals and form clamping matching of the bottom shell, the upper shell and the signal terminals. The signal terminal block is between drain pan and epitheca to be convenient for signal terminal and the assembly at drain pan, epitheca, thereby be favorable to improving this backup protector's assembly efficiency.
