Abstract
The utility model discloses a kind of automotive controls waterproof construction, comprise button (1), housing (2), support (3), conduction rubber cushion (5), printed circuit board (6), base (7) and contact pin (8), contact pin (8) is embedded in base (7), printed circuit board (6) is assemblied on base (7), contact pin (8) is welded on printed circuit board (6), conduction rubber cushion (5) covers printed circuit board (6) top, and base (6) and housing (2) fasten.The utility model energy available protecting electric switch internal component, circuit functional, thus the validity ensureing automobile switch under abnormal condition.
Description
Technical field
The utility model patent relates to a kind of waterproofing protection structure of automotive controls.
Background technology
With automotive technology development, automobile electronic switch progressively will substitute traditional mechanical switch.As switch, have " anti-pinch ", remote control " open and close ", the controlling functions such as " enter " without key, the demand of these hommizations, only has electronic switch to realize.Some specific positions simultaneously on automobile, as door and window position, these places very easily intake and ponding.And be arranged on the switch of these positions, if protection is done badly, current or other foreign matters, after entering switch internal, very easily carry out oxide etch to the components and parts on printed circuit board and dew copper wire, cause switch failure.Equally, amass the water in car door, can raise along with vehicle interior temperature, ponding produces steam, enters switch internal corrosion switching component, switching function was lost efficacy by construction of switch gap.For making switch normally work, even if when switch external waterproof cannot ensure completely, switch internal current design manual of protective structures necessitates.
Summary of the invention
The technical problem that the utility model patent will solve is: the problem entering switch for water, steam or other foreign matters, provides a kind of inner protective structure of automotive controls.
The technical scheme of the utility model patent is:
A kind of automotive controls waterproof construction, comprise button, housing, support, conduction rubber cushion, printed circuit board, base and contact pin, contact pin is inlayed in the base, printed circuit board is assemblied on base, contact pin is welded on printed circuit board, conduction rubber cushion covers above printed circuit board, and base and housing fasten.
Above conduction rubber cushion, arrange support, support is frame structure, and support interference circle is arranged at bottom, and the rib that inner walls is stretched out makes support be squeezed on conduction rubber cushion
Printed circuit board is contained in chassis interior, the sidewall of base higher than printed circuit board, conduction rubber cushion by the sidewall of printed circuit board and base along coated, the conduction edge of rubber cushion and the sidewall mating surface of base are step surfaces
Side is designed with step, under being contained in the step of housing in the step base of conduction rubber cushion with conduction rubber cushion cooperation place.
Base with the step mating surface of conduction rubber cushion are provided with base interference circle.
Osculum is offered in housing side, and osculum is higher than conduction rubber cushion.
On conduction rubber cushion, there is printing opacity wall at the position of corresponding button, printing opacity coping wall thickness 0.1-0.2mm.
The beneficial effects of the utility model:
The utility model is that the internal electrical structure of automotive controls devises a kind of safeguard structure, with conduction rubber cushion, printed circuit board is entirely coated, and use the interference limit of support that conduction rubber cushion and printed circuit board are more fitted, reduce the gap between conduction rubber cushion and printed circuit board, prevent switch top possibility current and foreign matter from entering printed circuit board surface, corrosion components and parts and circuit.In addition, on base, contact pin adopts insert structure, and printed circuit board is included in chassis interior by base, makes to be sealed bottom switch, prevents steam from entering switch internal, components and parts on etched wiring plate.This utility model substantially increases the anti-foreign matter performance of automotive controls, thus adds the useful life of automotive controls.
Housing side wall thickness abdicates step surface, comprises wherein by conduction rubber cushion side interference limit and base, base with conduction rubber cushion side mating surface increases interference circle, kills in casing step face, realize the sealing of conduction rubber cushion and housing by conduction rubber cushion side.
Housing is provided with osculum, and the abnormal water flow energy of switch internal is discharged in time.

Fig. 1 is the utility model patent structure schematic diagram.
Fig. 2 is partial structurtes enlarged drawing.
Embodiment
Base 7 adopts insert structure, is set in by contact pin 8 on base 7, and printed circuit board 6 is assemblied on base 7, base 7 sidewall is higher than printed circuit board 6, printed circuit board 6 is contained in base 7 inner, realizes sealing bottom switch, outside base 7 sidewall, be provided with ledge structure; Contact pin 8 is welded on printed circuit board 6, and conduction rubber cushion 5 covers on printed circuit board 6, and carries out entirely coated to printed circuit board 6 and base 7 sidewall, and conduction rubber cushion 6 edge stretches out step base by coated for the step of base 7 sidewall.Housing 2 side is designed with step with the cooperation place, step base of conduction rubber cushion 6, the step base of conduction rubber cushion 5 side is stretched in housing 2 step surface, the ledge structure of base 7 designs base interference circle 70, rubber cushion 5 side will be conducted electricity even at the cost of one's life in step surface, realize the sealing between conduction rubber cushion 5 and base 7, switch top may be entered foreign matter and completely cut off on conduction rubber cushion 5 top; The support 3 of sealing is installed between conduction rubber cushion 5 and housing 2, support 3 bottom design crosses support interference circle 30, the rib that housing 2 inwall stretches out is to pressing down support 3, support 3 is made to compress conduction rubber cushion 5, reduce gap between conduction rubber cushion 5 and printed circuit board 6, prevent gap Absorb Water phenomenon between conduction rubber cushion 5 and printed circuit board 6, avoid affecting printed circuit board 6; Base 7 and housing 2 fasten, and osculum 4 is offered in the minimum side on housing 2 after the assembling of selector switch car load, and osculum 4, higher than conduction rubber cushion 5, can be discharged entering the abnormal current of switch internal in time.Button 1 is arranged on above housing 2, and on conduction rubber cushion 6, the position of corresponding button 1 is provided with printing opacity place, printing opacity place wall thickness 0.1 ~ 0.2mm.
