Description
Technical field
The present invention relates to field of sealing technology, are padded more particularly to a kind of steam Electromagnetic heating plate seal.
Background technology
Currently, in electronics field, silastic material is widely used and makes sealing gasket, and this type seal pad,
Due to having a single function, sealing structure is poor, thus can not meet well electronics steam, double electromagnetic sealing want
It asks.
On the other hand, conductive rubber has small volume resistivity, advantages of good shielding performance, pressure as a kind of electromagnetic sealing material
The advantages that contracting is good, structure type is various has broad application prospects in electronic assemblies manufacturing field.But due to conductive rubber
Corrosion resistance itself is poor（General conductive compositions are that aluminium plates Argent grain）, easily because corrosion causes in having the environment of steam or salt fog
Failure, therefore be not suitable for applied in the electronics under severe environmental conditions.And used at present in fields such as space flight, aviations
Conductive rubber, mainly inside the enclosed construction of electronics, environmental condition is preferable, therefore the application of conductive rubber is by environment item
The limitation of part, so how to solve the above problems is those skilled in the art always in the problem of thinking.
Invention content
It is an object of the invention to：Overcome the above-mentioned problems in the prior art, proposes that a kind of steam Electromagnetic heating is flat
Plate sealing gasket realizes that the dual purpose of steam, electromagnetic sealing, the liner had both had traditional silicon rubber by unique design
The water vapor seal ability of gasket, while having the electromagnetic shielding feature of conductive rubber sealing gasket again, it may be implemented using item
In the case of part is identical, waterproof seal achievees the effect that realize electromagnetic shielding while IPX7 grades.
The purpose of the present invention is realized by following technical proposals：
A kind of steam Electromagnetic heating plate seal liner, including：Gasket body, the gasket body by conductive rubber portion and
Electro-insulating rubber portion two parts are constituted, and the electro-insulating rubber portion is coated on conductive rubber portion outer circumferential, the gasket body middle part
With working hole, the gasket body periphery has several mounting holes.
A kind of steam Electromagnetic heating plate seal liner of the present invention, conductive rubber portion surface has at working hole
There is conductive seal protruding ring.
A kind of steam Electromagnetic heating plate seal liner of the present invention, electro-insulating rubber portion surface has insulated enclosure convex
Play ring.
A kind of steam Electromagnetic heating plate seal liner of the present invention, the height of the conductive seal protruding ring are less than insulation
The height of seal convexity ring.
A kind of steam Electromagnetic heating plate seal liner of the present invention, the conductive rubber portion is by rubber and the silver-plated conduction of aluminium
Particle or glass silvering conductive particle mix, and the volume resistivity in the conductive rubber portion is less than or equal to 0.008 Ω cm,
Compression set rate is less than 35%.
A kind of steam Electromagnetic heating plate seal liner of the present invention, the conductive rubber portion and electro-insulating rubber portion pass through sulphur
Change processing global formation.
A kind of steam Electromagnetic heating plate seal liner of the present invention, the conductive seal protruding ring and insulated enclosure protrusion
The cross sectional shape of ring is arc-shaped.
The exterior contour of a kind of steam Electromagnetic heating plate seal liner of the present invention, the gasket body is rectangle.
According to above-mentioned technical proposal, the beneficial effects of the invention are as follows：
1, gasket body is made of conductive rubber portion and electro-insulating rubber portion two parts, while being realized and being produced in electronics field
The purpose of product waterproof sealing and electromagnetic shielding.
2, conductive seal protruding ring and insulated enclosure protruding ring are set, the contact surface effectively sealed can be reduced, to subtract
Caused by small manufacture misses the case where seal failure.
3, the height of conductive seal protruding ring is less than the height of insulated enclosure protruding ring, and the isolation of insulated enclosure protruding ring is external
Steam plays the role of protecting inner conductive rubber and component, conductive seal protruding ring and electric connector flange and machine box surface
Plate fits closely, and to ensure that electrical contact is continuous, plays the role of electromagnetic sealing, if the height of conductive seal protruding ring is 0.4mm,
Insulated enclosure protruding ring 0.6mm.
4. by global formation, sealing effect not only ensure that, but also the connection improved between insulated part and current-carrying part is strong
Degree.
