Starter overload protection structure

Abstract

A starter overload protection structure comprises a sheath; a central groove is arranged in the sheath; a fuse sheet is plugged in the central groove of the sheath; two ends of the fuse sheet extend outside the sheath; the root of the extend end, corresponding to the sheath front side, of the fuse sheet is in a folded shape; the extend end, corresponding to the sheath front side, of the fuse sheet is provided with a gap; the cross section, corresponding to the gap, of the fuse sheet is smaller than that of other positions on the fuse sheet; the extend end, corresponding to the sheath back side, of the fuse sheet is welded with an electric brush copper wire; welding points of the electric brush copper wire can fix the fuse sheet in the central groove of the sheath. The benefits are that the electric brush copper wire is connected with an electric brush through the fuse sheet; when abnormity happens, the fuse sheet corresponding gap firstly melts so as to disconnect the whole starting circuit; even though the starter is already partially burned, further burning of the starter and external circuits can be prevented, thus protecting the whole vehicle.

Description

Technical field [0001] The present invention involves the use of the starting motor overload protection structure with a motivation power brush in various vehicles. Background technique [0002] The traditional starting motor power brush group is directly welded with the lead, and does not have the function of anti -overload burning.During the use of the starter, the failure of motivation has occurred, that is, whether the motivation switch occurs with adhesion or an abnormal situation of the ignition lock, it will cause the starting motor to continue continuously.In this case, the starting circuit has been in a diverse state. When the starter continuously works until the internal component or the external wire bundle of the vehicle appears, the entire starting circuit will be disconnected.The entire failure process will lead to extreme phenomena such as high -temperature melting in the external circuit or starter of the vehicle, which will cause the vehicle to fire in severe cas...
