As preferably, described motor is DC micromotor, is shaped as flat.
The contact of movable contact spring and movable contact spring riveted joint, in order to reduce the resistance of riveting point, movable contact spring is made of silver layer and phosphor-copper layer, and the riveting point is on silver layer.
For so that the utility model box volume is less, described guide plate becomes an angle of 90 degrees with movable contact spring, and movable contact spring and motor be arranged in parallel.
Operation principle according to above-described high-power latching relay: the small planetary gear rotation of driven by motor planetary gear reducing mechanism, thereby driving end cap rotates, the gear driven spur rack of end cap does reciprocating linear motion, thereby promote to be arranged on the movable contact spring motion on the guide plate, when the utility model is used on the instrument and meter, realize the on/off of the contact of movable contact spring and static contact by control circuit conversion motor both positive and negative polarity.Because the gear ring of planetary gear reducing mechanism does not move, thereby this mechanism has auto-lock function, the assurance planetary gear reducing mechanism can only be done accurate motion under the drive of motor, the structure of casing is optimized simultaneously, so that the casing manufacturing process is easier, has further reduced cost.
Thereby, the utlity model has the characteristics such as simple in structure, easy to use, that cost is low.
