Description
Technical field
The utility model relates to a kind of electromagnetic switch on starter, specifically, relates to a kind of can effectively preventing on starter because steam enters the fully-sealed electric magnetic switch causing terminal to corrode.
Background technology
Current vehicle majority uses electric starter motor to start the engine of vehicle, and the electric energy conversion of storage battery is mechanical energy by starter, drives engine running, pilots engine.
Starter is made up of direct current machine, transmission mechanism and controlling organization, and during vehicle launch engine, motor generate torque, this torque makes it be delivered to engine flywheel gear ring by driven wheel by transmission mechanism, and then pilots engine.
Fig. 1 shows a kind of existing electromagnetic switch structure of starter schematic diagram.Its structure comprises: hold-in winding 101, pull in winding 102, only seat 103, movable contact spring 104, supporting cover 105, terminal 106, sealing gasket 107, body 108, return spring 109, plunger mandrel 110, skeleton 111, terminal cavities 112.
When ignition switch is energized, pull in winding 102 and hold-in winding 101 are energized simultaneously, produce electromagnetic force, electromagnetic force drives plunger mandrel 110 to move right, return spring 109 is compressed, plunger mandrel 110 drives movable contact spring 104 to move towards terminal 106 direction, movable contact spring 104 and terminal 106 are connected afterwards, plunger mandrel 110 continues to move right, until plunger mandrel 110 and only seat 103 offset, plunger mandrel 110 moves right in process, the first slow-speed of driven wheel, when movable contact spring 104 is connected with terminal 106, driven wheel turns soon, pilots engine.
After engine start, unclamp ignition switch, the magnetic force that solenoid produces disappears, plunger mandrel 110 is moved to the left under the effect of return spring 109, shift fork (figure does not show) is driven to make driven wheel depart from flywheel ring gear, drive movable contact spring 104 and terminal 106 to disconnect simultaneously, disconnect main circuit thus, and then starter shuts down.
Due to good metals of conductivity such as terminal material many uses copper, its thermal conductivity is often also fine, therefore easily cool, steam is easily adsorbed in terminal contact position, when starter works in moister environment, as Brazilian, African etc., terminal contact position is corroded, cause main contacts to connect or conductivity reduces greatly, therefore, the waterproof requirement of electromagnetic switch is of crucial importance.
Electromagnetic switch waterproof main seal position comprises in the market: between (1) supporting cover 105 and body 107; (2) (not shown) between (3) trip bolt and supporting cover 105 between terminal 106 and supporting cover 105, sealing means is rubber seal, supporting cover position part can reach IPX7 seal standard, but steam still has two approach to enter in terminal cavities causes terminal to corrode.Reference Fig. 2, Fig. 2 are steam access path schematic diagram in the existing electromagnetic switch course of work.As shown in Figure 2: (1) steam enters terminal cavities 112 by plunger mandrel 110 and the gap only between seat 103; (2) steam enters terminal cavities 112 by the wire hole on only seat 103 and sealing gasket 107.Reason is as follows: the first, and extraneous water and steam can enter starter inside, then enter switch via Driving terminal chamber.The second, for ensureing frame strength, skeleton needs boiling water in the course of processing, and skeleton itself contains comparatively juicy, and steam is easily adsorbed in assembling process coil surface, and these steam all can pass through only seat wire hole and enter terminal cavities, cause terminal to corrode.Therefore, a kind of electromagnetic switch overcoming above-mentioned defect of exploitation is badly in need of.
