Description
Technical field
The utility model is related to relay technical fields, more particularly to a kind of high pressure pre-charge-relay, for example apply
In electric vehicle.
Background technology
Precharge management is essential important link in new-energy automobile, and main function is to electric machine controller
The bulky capacitor of (i.e. inverter) charges, and to reduce spark arcing when main relay is closed, rush of current is reduced, to improve master
The electrical endurance ability of relay and increase safety.High pressure pre-charge-relay is connected when charging initial to be powered to capacitance,
Time is very short, and then main relay is closed (preliminary filling relay disconnects at this time) after the completion of capacitor charging, therefore requires to be to bear in short-term
Certain load, while a protective effect is played to main relay.
Existing high-voltage relay, due to high pressure, contact often will produce stronger electric arc when being connected, and it is hidden to cause safety
Suffer from, and pitting of contacts is big, it is necessary to arc extinguishing technology is used, and the arc extinguishing method of high-voltage relay generally uses vacuum under closed environment
Or filled with high pressure gas, design and technique assembly are complex, and since electric current, voltage are larger, product is relatively also larger, takes material
Fei Cai, of high cost, if pre-charge-relay also designs like this, cost is also relatively high, accordingly, it is considered to precharge relay
How the work characteristics of device designs a kind of easy, arc quenching chamber structure for easily realizing, can achieve the effect that arc extinguishing and simplification
Manufacture craft reduces cost, becomes urgent technical problem to be solved in the field.
The arc-chutes scheme of existing high pressure pre-charge-relay mainly has two kinds, and one is by arc-chutes and relay master
Body is designed to two separate components, and then two separate components combine again；Another kind is by arc-chutes and shell integrated injection molding
Molding；Either the former or the latter, are primarily present as following drawbacks：
1, also across one layer of plastics between relay main body and the magnetic patch of arc-chutes, magnetic patch is remote from contact, and magnetic field intensity is weak,
Arc quenching effect is poor；
2, U-shaped magnetic conductive board needs to be arranged pin configuration for being installed on pcb board, it is also desirable to be reserved on pcb board
Corresponding two location holes have also needed scolding tin process to fix entire arc-chutes when installing relay, and when mounted,
Cause the cumbersome of installation；
3, U-shaped magnetic conductive board, the magnetic patch for being installed on arc-chutes have and are exposed at outside relay on one side, and relay is needed to install
After on pcb board, the scope of freedom is fixed by pcb board, causes U-shaped magnetic conductive board and magnetic patch easily by extraneous aqueous vapor, salt fog, harmful
The institutes such as gas (such as SO2 etc.) burn into pollutes and performance is made to decline.
Utility model content
The purpose of the utility model is to overcome the deficiencies of the prior art, provide a kind of high pressure pre-charge-relay, pass through
Structure is improved, on the one hand, the magnetic field intensity that arc-chutes can be enhanced, to improve arc quenching effect；On the other hand, U-shaped can be removed to lead
The pin configuration of magnetic sheet, to simplify structure；And there is easy to assembly, low manufacture cost, and prior art drawback can be eliminated
The characteristics of.
