Description
Technical field
Patent of the present invention relates to the waterproofing protection structure of a kind of automotive controls.
Background technology
With automotive technology development, automobile electronic switch will progressively substitute traditional mechanical switch.Such as switch, will have " anti-pinch ", remote control " open and close ", " enter " etc. control function without key, the demand of these hommizations, only electrical switch are capable of.Some specific positions on automobile simultaneously, such as door and window position, these places easily intake and hydrops.And it is arranged on the switch of these positions, if protection is done badly, current or other foreign bodies, behind access switch inside, easily carry out oxide etch to the components and parts on printed circuit board and dew copper wire, cause switch failure.Equally, amassing the water in car door, can raise along with vehicle interior temperature, hydrops produces steam, by construction of switch gap access switch internal corrosion switching component, makes switching function lose efficacy.For making switch normally work, though switch external is waterproof cannot be completely secured in the case of, switch internal current design manual of protective structures necessitates.
Summary of the invention
Patent of the present invention to solve the technical problem that: for water, steam or the problem of other foreign body access switchs, it is provided that the inner protective structure of a kind of automotive controls.
The technical scheme of patent of the present invention is:
A kind of automotive controls safeguard structure, including 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 fastens with housing.
Conduction rubber cushion be provided above support, support is frame structure, and support interference circle is arranged at bottom, the rib that inner walls is stretched out make support be squeezed in conduction rubber cushion on
Printed circuit board is contained in chassis interior, and the sidewall of base is higher than printed circuit board, and conduction rubber cushion will coordinate face to be step surface along cladding, the edge of conduction rubber cushion and the sidewall of base on the sidewall of printed circuit board and base
Side is designed with step with the conduction rubber cushion place of cooperation, is included on the step base of conduction rubber cushion under the step of housing.
Step at base with conduction rubber cushion coordinates and is provided with base interference circle on face.
Osculum is offered in housing side, and osculum is higher than conduction rubber cushion.
On conduction rubber cushion, there are printing opacity wall, printing opacity coping wall thickness 0.1-0.2mm in the position of corresponding button.
Beneficial effects of the present invention:
The present invention is that the internal electrical structure of automotive controls devises a kind of safeguard structure, with conduction rubber cushion, printed circuit board is coated with entirely, and use the interference limit of support to make conduction rubber cushion more fit with printed circuit board, reduce the gap between conduction rubber cushion and printed circuit board, prevent switching top probability current and foreign body enters printed circuit board surface, corrosion components and parts and circuit.It addition, contact pin uses insert structure on base, and printed circuit board is included in chassis interior by base, makes to be sealed bottom switch, prevents inside steam access switch, components and parts on etched wiring plate.This invention substantially increases automotive controls anti-foreign body performance, thus adds the service life of automotive controls.
Housing side wall thickness concedes step surface, comprises wherein by conduction rubber cushion side interference limit and base, coordinates increase interference circle on face at base with conduction rubber cushion side, kills in casing step face by conduction rubber cushion side, it is achieved conduction rubber cushion and the sealing of housing.
Housing is provided with osculum, makes switch internal exception current to discharge in time.
Accompanying drawing explanation
Fig. 1 is patent structure schematic diagram of the present invention.
Fig. 2 is partial structurtes enlarged drawing.
Detailed description of the invention
Base 7 uses insert structure, is set on base 7 by contact pin 8, and printed circuit board 6 is assemblied on base 7, and base 7 sidewall is higher than printed circuit board 6, printed circuit board 6 is contained in base 7 internal, it is achieved sealing bottom switch, base 7 sidewall is externally 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 is entirely coated with printed circuit board 6 and base 7 sidewall, and conduction rubber cushion 6 edge stretches out step base and is coated with by the step of base 7 sidewall.Housing 2 side is designed with step with the step base place of cooperation of conduction rubber cushion 6, the step base of conduction rubber cushion 5 side is stretched in housing 2 step surface, base interference circle 70 is designed on the ledge structure of base 7, 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 is completely cut off on conduction rubber cushion 5 top possibly into foreign body；The support 3 sealed is installed between conduction rubber cushion 5 and housing 2, support 3 bottom design crosses support interference circle 30, the rib stretched out on housing 2 inwall is pressed downward against 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, it is to avoid affect printed circuit board 6；Base 7 fastens with housing 2, housing 2 selects the minimum side after switch car load assembling offer osculum 4, and access switch internal abnormality current, higher than conduction rubber cushion 5, can be discharged by osculum 4 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 at printing opacity, wall thickness 0.1 ~ 0.2mm at printing opacity.
