Description
Technical field
The present invention relates to Vehicular starter electromagnetic switch, the anti-freeze starting of particularly a kind of band icing concentrated area is electromechanical
Magnetic switch.
Background technology
Traditional starter relay include shell, set on the fixed contact pedestal of outer casing bottom, in fixed contact pedestal
Two static contacts, are arranged in the dynamic tactile of annular brace limit base center at the annular brace limit base being fixed on above fixed contact pedestal
Head rod is fixed on movable contact rod lower end and the movable contact spring vertical with movable contact rod, set on movable contact rod lower end and fixed contact pedestal bottom
Resetting spring between face, the sleeve for being set in annular brace limit base upper periphery, the annular formed set on sleeve and shell
Electromagnetic coil in space, the dynamic iron core in sleeve and using spring supporting at the top of annular brace limit base, wherein, it moves
Contact is one and controls the double contact structure for flowing through starter armature electric current, and movable contact spring both ends correspond to two static contacts respectively.When
Electromagnetic coil charges, and dynamic iron core moves down, and so as to which movable contact rod and movable contact spring be driven to move down, makes movable contact spring both ends quiet with two respectively
Contact connects conducting electric current, but its there are the following problems：When electromagnetic switch outside air temperature reduce, heat start from switch housing to
Outer loss, the material of two T-bolts as static contact is metal, therefore the plastic material around the ratio of heat losses is quiet
Faster, temperature is down to 0 DEG C hereinafter, then the vapor of switch internal is preferentially in two stationary contact head surfaces to contact base prior to other component
Contact region congeal into ice, and contact freeze electromagnetic switch be unable to turning circuit, starter can not normal starting.
In order to solve the problems, such as that static contact freezes in above-mentioned starter switch, starting circuit can not be connected,
CN203931956U discloses the electromagnetic switch that a kind of automobile plays power failure machine, is smashed using the teeth part shown in serial number 11
The ice tied on movable contact spring, but in electromagnetic switch in actual use, since static contact ice condition is than moving contact
Ice condition it is more serious, the situation that electromagnetic switch contact cannot be connected is often caused by caused by the icing of stationary contact head surface.
Therefore, what which solved the problems, such as is accidental, fundamentally solves the problems, such as static contact icing, i.e., not from
Fundamentally solve the problems, such as engine fail to start.
CN105280403A discloses a kind of anti-freeze starter relay with double contact, comes from overall structure
It sees in the technical solution of the patent application publication and has used two sets of contact mechanisms, operation principle is：When being influenced stationary contact by weather
When head surface freezes, from external environment farther out, the sectional area small distance that heat conducts in metallic plate is long for auxiliary static contact, so
It will not freeze.At this moment if key door acts, upper and lower movable contact spring declines, and lower movable contact spring both ends can be touched on two static contacts, because
There is ice for stationary contact head surface, therefore cannot be connected, and assist stationary contact head surface without ice, upper movable contact spring both ends are in contact with it rear electric current meeting
It being flowed along sheet metal, sheet metal sectional area is small, resistance is big, so can acutely be generated heat by high current, sheet metal hair
After the heat gone out melts the ice of stationary contact head surface, static contact, which is begun to turn on, flows through high current, and starter starts to work normally, from
Fundamentally solve the problems, such as that contact icing can not normal starting.But two sets of contact mechanisms introduce the problem of new：Complicated,
It is of high cost, volume is big.If problem above is placed on the high-power diesel vehicle not bery stringent to volume requirement still to be received,
But the program there is clearly disadvantageous part, narrow scope of application on the passenger car being strictly required in volume.
CN105280442A discloses a kind of anti-freeze starter relay with helical spring contact, devises uniqueness
Helical spring contact structure, operation principle is：When being influenced the icing of stationary contact head surface by weather, it is looped around around static contact
Helical spring because itself spring wire it is long, heat conduction distance, so will not freeze, at this moment if key door moves
Make, movable contact spring declines, and can first encounter the helical spring around static contact, then touch on static contact, because of at this moment static contact table
There is ice in face, therefore cannot be connected, but helical spring surface, without ice, electric current can be flowed along helical spring, should be flowed through originally tactile
The circuit of point changes the lower part that static contact is flowed to by the helical spring by both sides, because helical spring is high resistivity made of metal
Into, so can acutely be generated heat by high current, after the ice of heat thawing stationary contact head surface that helical spring is sent out, static contact
It begins to turn on and flows through high current, ensure that starter starts to work normally, solve the problems, such as that contact icing can not normal starting.But
There is also insufficient for the program：Because its helical spring contact can all pass through every time in switch connection moment there is an ablation
The upper end for crossing spring after the consumption of multiple ablation is very nearly the same with the height of static contact, cannot be reliable in end of lifetime
Prevent icing phenomenon from occurring.To sum up, existing anti-freeze starter relay still needs to improve.
