The utility model is on the basis of one group of static contact group of prior art and movable contact spring group, change the size and dimension of movable contact spring, increase the quantity of static contact group and movable contact spring group, and the structure of corresponding adjustment elastic pressure parts mechanism, reach the effect that to lead to big electric current, make this small size relay possess bigger power.
For being separated the electric arc that is produced with static contact, movable contact spring draws relay, the utility model further is set to high power relay and comprises the arc chute sheet that is arranged on the shell, the top position of corresponding motion block cover plate forms a plurality of placed cavities that are arranged in parallel on the shell, the moving contact of the oblique setting of each placed cavity on movable contact spring, connect before and after the placed cavity, form several grooves that be arranged in parallel on each placed cavity, arc chute sheet correspondence is arranged in each groove.By the arc chute sheet electric arc is exported in the air, guaranteed the trouble free service of relay.
In order to guarantee functional reliability, the utility model further be set to 2 often open that static contact be arranged in parallel and between have the gap, on the shell on the corresponding outer wall of often opening static contact one side the centre position extend to form to 2 gaps of often opening between the static contact and climb the arc plate, the opposite side of climbing the arc plate on the shell relatively oppositely extends to form flash barrier.Increase by 2 climbing arc distances of often opening between the static contact by climbing the arc plate; When disjunction, the effect of isolated electric arc is played in the setting of flash barrier.
For easy accessibility, the utility model further is set to form buckle in the two bottom sides of pedestal again, and shell adopts transparent configuration, forms the buckling groove corresponding with buckle on the shell, and shell constitutes clamping with pedestal and is connected.By the clamping ways of connecting, be convenient to the dismounting of product.
