Starter electromagnetic switch and starter comprising the same

Abstract

The invention relates to an electromagnetic switch of a starter. After a starter in the prior art starts, the phenomenon of material adhesion, or contact point fusion welding or the like often happens between a contact element and a binding post of the starter electromagnetic switch and causes burn of the electromagnetic switch. Therefore, the electromagnetic switch of the starter comprises a sleeve element, the sleeve element is fixedly connected with the opposite ends of a shaft rod and a pushing rod of the electromagnetic switch along the axial direction of a shell, at least two slots are formed in at least one end of the sleeve element, elastic hanging arms are formed by the at least two slots in the sleeve element, wherein the number of the elastic hanging arms corresponds to that of the at least two slots, and meanwhile a first joint part and a second joint part are formed on each elastic hanging arm of the sleeve element and are respectively connected with the two opposite ends of the pushing rod and the shaft rod in a buckling mode. Due to the using of the electromagnetic switch, the pushing rod of a movable iron core and the shaft rod of the movable contact element are fixedly connected together relatively easily, and the occurrence of the contact point fusion welding can be effectively avoided.

Description

technical field [0001] The invention relates to an electromagnetic switch of a starter, which is used for controlling the on-off of the starter circuit and the moving out and back of the driving gear. Meanwhile, the present invention also relates to a starter for an engine including an electromagnetic switch. Background technique [0002] Using an electric starter to start a motor vehicle's engine is almost the only way to start a modern motor vehicle, such as an automobile. The function of the starter is to convert the electric energy stored in the battery into mechanical energy through the starter under normal conditions of use, and drive the engine of the motor vehicle to run at a high enough speed so that the engine automatically idles. [0003] The electric starter is referred to as the starter, which is composed of a DC motor, a transmission mechanism and a control mechanism. The DC motor generates rotational torque under the action of the DC voltage of the battery; ...
