Description

Technical Field

[0001] The utility model relates to the technical field of automotive starter parts, and particularly relates to an electromagnetic switch for an automotive starter. Background Technique

[0002] A starter, also called a motor, converts the electrical energy of a storage battery into mechanical energy to drive the engine flywheel to rotate and achieve the start of the engine. Starters are classified into DC starters, gasoline starters, compressed air starters, etc. according to their working principles. Most internal combustion engines use DC starters, which are characterized by a compact structure, simple operation and easy maintenance. An electromagnetic switch, as the name implies, is a switch controlled by an electromagnet, that is, a combination of an electromagnet and a switch. When the electromagnet coil is energized, an electromagnetic attraction force is generated, and the movable iron core pushes or pulls the switch contact to close, thereby connecting the controlled circuit. Electromagnetic switches are widely used in various industries, and the most common one is the contactor in the industrial field. The electromagnetic switch is a control switch on the starter and is one of the three major components of the starter (DC motor, transmission engagement mechanism, electromagnetic switch). Its working principle is that after the coil is energized, an electromagnetic attraction force is generated to move the movable iron core, so that on the one hand, the transmission engagement mechanism is pulled to move the pinion of the starter forward to engage with the flywheel ring gear of the engine, and on the other hand, the switch contact is pushed to close, so that the DC motor is energized and rotated, thereby driving the engine to start.

[0003] The application number is CN201821632858.X, which discloses a new type of electromagnetic switch for an automotive starter, including an armature assembly and a B terminal. The B terminal includes an insulating cover, a B bolt, a B static ring, a flat washer and a spring washer. The gap between the head of the B bolt and the plane of the B static ring is 0, and the B bolt and the B static ring are connected by interference fit; in the area where the B bolt is connected to the B static ring, straight threads are provided on the B bolt; the armature assembly includes an armature, a slide rod, a return spring sleeved at the tail end of the slide rod, and a moving ring sleeved outside the armature. The armature is sleeved outside the slide rod. One end of the armature is provided with a baffle. The armature drives the slide rod and the moving ring to move back and forth along its axis. When the moving ring moves, the B terminal and the M terminal are connected together. Through this electromagnetic switch, the problems of poor contact between the moving ring and the M static ring and the B static ring and low bearing capacity can be effectively solved, and the volume of the electromagnetic switch can be reduced.

[0004] Although the above-mentioned utility model can effectively solve the problems of poor contact between the moving ring and the M static ring and the B static ring and low bearing capacity through this electromagnetic switch, and reduce the volume of the electromagnetic switch, the drawback is that when the device is overhauled for internal parts, the disassembly of its housing is somewhat cumbersome and difficult.

[0005] Therefore, it is necessary to change the outer shell of the device into the current convenient installation shell component, which can provide certain convenience during the installation and disassembly of the internal part when using this device, thus bringing certain convenience during use.
