Abstract
This invention discloses one electron product outlook metal parts earth method, which comprises the following steps: firstly opening holes on outlook metal part surface area to be covered on electron product with non-metal or metal parts; then spraying dry conductive glue on holes to make them connected to the conductive paint of the metal or non-metal shell; the conductive painting is connected to earth. This invention method has properties of fix earth connection and low resistance and can realize product earth connection within small area.
Description
Technical field
The present invention relates to a kind ofly, relate in particular to a kind of the outside metal parts earthing method of electronic product in electronic product electrostatic defending method for designing.
Background technology
At present, electronic product such as mobile phone, PDA is the metal-like of outstanding outward appearance, designing some through its housing outer surface of being everlasting is the decoration parts of material with metals such as stainless steel, aluminium, and this brings difficulty to Electrostatic Protection of Electronic Products, metal parts ground connection could must be solved sometimes.Because metal parts and cabinet are generally bonding with double faced adhesive tape, make traditional earthing mode as: welding, Elastic Contact etc. can not be used, and as the methods such as conductive fabric, conducting foam of pasting be difficult in the conducting effect that reaches stable ideal on the less contact area.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of outward appearance metal parts earthing method of electronic product, in less area (as 3mm
2) realize metal appearance spare quiet earth under the situation of insulating barrier of being separated by of electronic product.
For solving the problems of the technologies described above, the inventive method at first will be capped the zone of the outside metal parts and open aperture on the non-metal shell of the electronic product with non-metal shell and the outside metal parts, then at aperture place's point rapid-curing cutback conducting resinl, make described rapid-curing cutback conducting resinl link to each other this conductive paint ground connection with described the outside metal parts with the conductive paint of non-metal shell inner surface respectively.
The inventive method is owing to connect electronic product outward appearance metal parts and ground connection with the rapid-curing cutback conducting resinl, thereby has that ground connection is firm, resistance is low and advantage such as stable.
Description of drawings
Fig. 1 is a specific embodiment assembling exploded view of the present invention, when promptly the inventive method is applied in a mobile phone: plastic housing and Metal decorative part around the mobile phone screen and the assembling exploded view that connects their double faced adhesive tape;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the cutaway view along the Z-Z line of Fig. 2;
Fig. 4 is the enlarged drawing at A place among Fig. 3;
Among the figure: 1 plastic housing, the perforate on 2 plastic housings, 3 double faced adhesive tapes, 4 the outside metal parts (stainless steel), 5 rapid-curing cutback conducting resinls, 6 conduction enamelled coatings.
Embodiment
The inventive method at first will cover and perforation that does not influence outward appearance of zone design of the outside metal parts at the non-metal shell of electronic product, after metalwork and non-metal shell assemble, conducting resinl with a kind of rapid-curing cutback is applied to tapping, guarantee glue and metal with " " contact.After the dry sclerosis of conducting resinl, metal promptly with " " by firm being connected of conducting resinl, reach the ground connection purpose.The inventive method is particularly useful for being separated with between outward appearance metal parts and ground wire the electronic product of plastic casing.
The present invention is further described below in conjunction with the drawings and specific embodiments.
In this specific embodiment, the inventive method is applied on the mobile phone.As shown in the figure: Fig. 1 is a specific embodiment assembling exploded view of the present invention, when promptly the inventive method is applied in a mobile phone: plastic housing and Metal decorative part around the mobile phone screen and the assembling exploded view that connects their double faced adhesive tape; Fig. 2 is the front view of Fig. 1; Fig. 3 is the cutaway view along the Z-Z line of Fig. 2; Fig. 4 is the enlarged drawing at A place among Fig. 3.
In this specific embodiment: the plastic housing of mobile phone (non-metal shell) 1 bonds by double faced adhesive tape 3 with stainless steel appearance component (the outside metal parts) 4, design has aperture 2 on plastic housing 1, at perforate 2 place's point rapid-curing cutback conducting resinls 5, it is linked to each other respectively with the conductive paint 6 of stainless steel 4 with plastic housing 1 inner surface.After glue was stiff, stainless steel 4 promptly firmly linked to each other by conducting resinl 5 with conductive paint 6, promptly reaches the ground connection purpose.Conductive paint 6 is a ground connection in the present embodiment.
Under identical condition, if use to paste the earthing method of conductive fabric or conducting foam, resistance is about 50 Ω between stainless steel and conductive paint, and resistance can sharply raise after one hour, even opens circuit.Owing to adopt the inventive method to use conducting resinl, resistance is below 5 Ω but in the present embodiment.
In sum, this method uses the rapid-curing cutback conducting resinl through the perforation on the non-metal shell, with non-gold Belong to metal parts that enclosure covers and be connected ground wire with plastic housing inside and connect, with in the past method relatively Have ground connection firmly, the advantage such as stable and resistance is low.
Claims (1)
1, a kind of the outside metal parts earthing method of electronic product, this electronic product has non-metal shell and the outside metal parts, and described non-metal shell inner surface has conductive paint, it is characterized in that, at first aperture is opened in the zone that will be capped the outside metal parts on described non-metal shell, at described aperture place's point rapid-curing cutback conducting resinl, make described rapid-curing cutback conducting resinl link to each other described conductive paint ground connection with described the outside metal parts with the conductive paint of non-metal shell inner surface respectively then.
