Relay

A relay, comprising:

• an insulating housing defining an accommodating cavity therein, wherein the accommodating cavity is open at one end thereof;
• two binding posts spaced apart from each other and disposed to the insulating housing, wherein an end of each of the two binding posts extends into the accommodating cavity;
• an insulating plate disposed within the accommodating cavity, movable between a first position and a second position, and comprising two connecting contacts spaced apart from each other and disposed on a first side of the insulating plate facing the binding posts, wherein the two connecting contacts are corresponding to the two binding posts in terms of position respectively, the insulating plate comprising multiple arc-extinguishing grids provided on the first side of the insulating plate facing the two binding posts, a mounting groove extending along a length direction of the insulating plate defined by the multiple arc-extinguishing grids;
• a fuse disposed within the mounting groove and between the two connecting contacts, wherein two ends of the fuse are electrically connected to the two connecting contacts respectively;
• a mounting base connected to the insulating housing;
• and
• a push rod movably disposed to the mounting base and connected to the insulating plate to push the insulating plate to move between the first position and the second position,
• wherein when the insulating plate is located at the first position, the two connecting contacts abut against the two binding posts respectively, and when the insulating plate is located at the second position, the two connecting contacts detach from the two binding posts respectively.
