Description
Technical field
This utility model relates to automobile starter technical field, is specifically related to a kind of automobile starter overload protection arrangement.
Background technology
The electric energy of accumulator can be converted into mechanical energy by automobile starter, drives engine flywheel to rotate, makes electromotor
It is transitioned into starting state by resting state, and is capable of operating voluntarily.
At present, partial automobile ignition system does not have overload protection arrangement or protection device design unreasonable, when user grasps
Making the reason such as improper or short-circuit when causing ignition circuit to occur abnormal, ignition circuit can not quickly disconnect, lasting big electric current meeting
Make starter temperature drastically raise, easily cause inflammable thing burning around that naked light occurs, in some instances it may even be possible to can cause more serious
Security incident.
Summary of the invention
The purpose of this utility model is to lack overload protection arrangement, or protection device to solve existing automobile starter
Design unreasonable, the problem of power-off weak effect, it is provided that a kind of reasonable in design, service-strong automobile starter overload protection
Device, can quickly disconnect when occurring abnormal in automotive ignition loop, it is to avoid serious security incident occurs.
The technical solution of the utility model is:
A kind of automobile starter overload protection arrangement, draws including the positive brush for being arranged on starter carbon brush frame
Line, negative pole brush-lead, outer leg, the sheath that is set in outer leg, it is characterised in that: described positive brush lead-in wire and
Be provided with connection sheet between outer leg, described sheath near connect sheet end face be provided with groove, be provided with in described groove heat-resisting absolutely
Edge backing plate, described heat resistant insulating padding plate center is provided with the through hole passed for outer leg, after described outer leg passes this through hole
Being welded on connection sheet, described connection sheet is provided with the first welding region of corresponding outer leg and corresponding positive brush lead-in wire
Second welding region, the cross-sectional area of described positive brush lead-in wire is less than the cross-sectional area of negative pole brush-lead.
Above-mentioned automobile starter overload protection arrangement, the first welding region of described connection sheet is positioned at connection sheet near outward
The middle part of side lead end, the quantity of described second welding region is two, is positioned at connection sheet near the both sides of carbon brush frame end, symmetrical
Arrange.
In above-mentioned automobile starter overload protection arrangement, the axial line of the through hole of described heat resistant insulating padding plate and sheath
Heart line overlaps.
The beneficial effects of the utility model are:
1, the cross-sectional area gone between due to the positive brush on starter carbon brush frame assembly is less than the horizontal stroke of negative pole brush-lead
Sectional area, i.e. increases the resistance of positive brush lead-in wire, when ignition circuit occurs abnormal, particularly during short circuit, and lasting big electricity
Stream can produce amount of heat at positive brush lead-in wire, makes positive brush lead-in wire to fuse within a short period of time, thus cutting
Individual ignition circuit, it is to avoid serious security incident occurs, and the position that fuses is inside starter, and fusing process peripheral is without bright
Fire, will not bring additional risk；
2, connecting sheet to be made by metal material, thermal capacity is relatively big, can share the heat of outer leg, draw outside reduction
Line reaches red heat shape probability of state；
3, heat resistant insulating padding plate is made by insulant, connection sheet plays the effect of insulated heat, it is possible to decrease protect
Overlap by the probability of boiling hotization；The through hole at heat resistant insulating padding plate center simultaneously, plays spacing effect, can prevent high temperature outer leg
Outer leg boiling hotization sheath under a stretching force after with other part bonding.
Accompanying drawing explanation
Fig. 1 is use structural representation of the present utility model；
Fig. 2 is the structural representation of heat resistant insulating padding plate of the present utility model；
Fig. 3 is the structural representation of connection sheet of the present utility model.
In figure: 1. outer leg, 2. sheath, 3. heat resistant insulating padding plate, 301. through holes, 4. connection sheet, 401. first welding
Region, 402. second welding regions, 5. positive brush lead-in wire, 6. negative pole brush-lead, 7. starter carbon brush frame.
Detailed description of the invention
As it can be seen, this automobile starter overload protection arrangement, including by for being just arranged on starter carbon brush frame 7
Pole brush-lead 5, negative pole brush-lead 6, outer leg 1, the sheath 2 being set in outer leg 1, it is connected to positive brush and draws
Connection sheet 4 and heat resistant insulating padding plate 3 between line 5 and outer leg 1 form, and described sheath 2 sets near the end face connecting sheet 4
Fluted, heat resistant insulating padding plate 3 is located in this groove, and described heat resistant insulating padding plate 3 center was provided with for leading to that outer leg 1 passes
Hole 301, described outer leg 1 is welded on connection sheet 4 after this through hole 301, the through hole 301 of described heat resistant insulating padding plate 3
Axial line overlap with the centrage of sheath 2.Described connection sheet 4 is provided with the first welding region 401 He of corresponding outer leg 1
Second welding region 402 of corresponding positive brush lead-in wire 5, the first welding region 401 of described connection sheet 4 is positioned at connection sheet 4 and leans on
The middle part of nearly outer leg end, the quantity of described second welding region 402 is two, is positioned at connection sheet 4 near carbon brush frame end
Both sides, are arranged symmetrically with.The cross-sectional area of described positive brush lead-in wire 5 is less than the cross-sectional area of negative pole brush-lead 6.
