Abstract

The utility model relates to a starter device with contactor function. The starter device comprises two coil frames, movable iron cores movably arranged inside the coil frames, coils wound outside the coil frames, two auxiliary yokes symmetrically arranged above and below the coils, two permanent magnets, two static iron cores, contact pressure springs arranged between the movable iron cores and the coil frames, and two contact pieces installed on the movable iron cores to enable the movable iron cores and the static iron cores to keep certain clearance. The starter device is characterized in that the two static iron cores are formed by bending a steel plate into U shape; the movable iron cores are formed by connecting two steel plates with a piece of quadrant iron into H shape. The starter device has the advantages that the processing and manufacture are convenient, and the mechanical life of the motor starter device is also prolonged.

Adopt the mode of riveted joint or welding to be formed by connecting between 31,33 and square steel 32 of two block plates described in the utility model.

The material of

steel plate

31,33 described in the utility model and the material of described square steel 32 are commaterial.

The utility model is formed with a pair of positioning boss 311,312 on described steel plate 31, this is positioned at the both sides of steel plate 31 and is positioning boss 311,312 and is symmetrical arranged.

The utility model is connected with the push rod 313,314 that is used for moving iron core position signalling output on described steel plate 31.

Push rod 313,314 described in the utility model adopts riveted way to be connected on the steel plate 31.

Be formed with a pair of positioning boss 331,332 on the steel plate 33 described in the utility model, this is positioned at the both sides of steel plate 33 and is positioning boss 331,332 and is symmetrical arranged.

The utility model is formed with the groove 333 that is used for plaing when mounted for contact pressure spring 4 the pre-determined bit effect on described steel plate 33.

The utility model is owing to made the dynamic and static iron core in the prior art after superposeing by some sheet metals and to change the thicker relatively steel plate of employing into and square steel is made separately with rivet, not only made things convenient for processing and fabricating, but also improved the mechanical endurance of motor starting apparatus.
