Simultaneously, save explanation, but the label that is to use is identical about the configuration aspects of having done in the prior art part to explain.
Here, be provided with a kind of on/off-type panel 1, thereby thereby contacting with main body 2 than lower curtate of its rear surface part is lockable in use.In other words, the conductive component that is arranged on the lower plate 4 of on/off-type panel 1 contacts on contact portion 11 with conductive component (pad 6) on being arranged on main body 2, this contact portion 11 is between rotating part 9 and 10, and on/off-type panel 1 supports on the main body 2 with being tilted.
Fig. 2 is the side view of folded form PC shown in Figure 1.
By accident, conductive component 5 is connected to and is arranged in lower plate 4 and the upper plate 3 and is used for preventing on the conductive surface of bad radiation, pad 6 be arranged on main body 2 in and be used for preventing that the conductive surface of bad radiation links to each other.In addition, the conductive surface of main body 2 and zero potential part (ground wire) thus 13 be connected with power supply 12 on the main body 2 and be connected.
According to this structure, in collapsible PC as example of the present invention, because conductive component 5 and pad 6 be mutually in the face of ground is connected, therefore, the conductive surface that prevents to produce bad radiation on/off-type panel 1 in is connected with zero electric the pad partly on the main body 2 by low resistance.Consequently, the electromagnetic noise of sending from on/off-type panel 1 has reduced.
Below,, of the present inventionly have the electronic device of on/off-type panel and be used for reducing the method for sending electromagnetic noise from the on/off-type panel to Figure 11 with reference to Fig. 2 describing in detail.
Fig. 3 shows the outside surface of the lower plate 4 of on/off-type panel 1.
With regard to the material of lower plate 4, can adopt metal material such as magnesium alloy or the like or synthetic resin material.Though can use different materials, the shape of lower plate 4 is identical.
At first, the lower plate of making by metal material 4 will be explained.
Combination with decorative surfaces (sprayed surface) the 14th, the outside surface of lower plate 4, in other words, be can from outside the surface seen, this surface was sprayed and had been improved outward appearance.Because this combination with decorative surfaces (sprayed surface) 14 scribbles coating, so it does not have electric conductivity.
The back of combination with decorative surfaces 14 (covering the surface) the 15th is positioned at the surface of lower plate 4, can not see from the outside, and in other words, be corresponding surface, rear surface with combination with decorative surfaces (sprayed surface) 14.Ostentatious rear surface (covering the surface) 15 needn't be improved its appearance and decorated, and spraying and decorating surface (sprayed surface) 14 o'clock, covers with this back 15 with mask, thereby coating can not adhered on this back 15 so that produce electric conductivity.In this method, owing to coverd with mask when spraying, therefore ostentatious rear surface (covering the surface) 15 compared with combination with decorative surfaces (sprayed surface) and had electric conductivity.Ostentatious rear surface (covering the surface) the 15th can prevent the conductive surface of bad radiation.
Thereby joint pin 16 is fixed into an integral body to lower plate 4 and upper plate 3 they is electrically connected.The post similar to joint pin 16 is arranged on the relevant position of upper plate 3, and fixes by screw.
Here, the electrical connection between lower plate 4 and the upper plate 3 not only guarantees by joint pin 16, but also guarantees by the mutual interlock of the shoulder part (not shown) on the edge that is arranged in lower plate 4 and upper plate 3.
Conducting position fixed part 17 is the parts on the lower plate 4, and this part is corresponding with the contact portion 11 that on/off-type panel and main body 2 generations contact and are arranged between rotating part 9 and 10.The conductive component of mentioning later is fixed on this part.
Combination with decorative surfaces 14 illustrates the basal plane of synthetic resin material or the surface that was coated with, and therefore needless to say, it does not have electric conductivity.
Ostentatious rear surface 15 all scribbles electrically-conducting paint, and it is as the conductive surface that can prevent bad radiation.When the 15 coated with conductive coating of ostentatious rear surface, combination with decorative surfaces 14 is coverd with so electrically-conducting paint can not adhere on the combination with decorative surfaces 14.
Explanation about the other parts of the lower plate 4 that adopts the synthetic resin material is identical with the above-mentioned situation of employing metal material, so its explanation has just been saved.
What provide explanation is: the current-carrying part 5 that is connected with the conductive surface that is used for preventing bad radiation is set on the lower plate 4 with said structure.
Fig. 4 is the drawing in side sectional elevation of the conductive component fixed part 17 of the expression lower plate 4 of looking from A direction shown in Figure 3.
Here, Fig. 4 represents to adopt the situation of the lower plate 4 of metal material, and also is the situation that the conductive strips 18 that play the web member effect that conductive component 5 is electrically connected with conductive surface are used as conductive component 5.
The ostentatious rear surface (covering the surface) 15 of the end face of conductive strips 18 by comprising lower plate 4 is bonded on the combination with decorative surfaces 14 (sprayed surface), can adopt normal tape (as, trade name: the CHOAEFOIL that makes by Taiyo Metal Net company limited) with electric conductivity.
This conductive strips 18 have organism such as synthetic resin and the analog stock as it, thereby and by blend such as stock and conductive materials being made band have electric conductivity.
Equally, as shown in Figure 4, because conductive strips 18 fold by the end in lower plate 4 and engage, this just need have pliability.Here, because this conductive strips 18 are made by organism such as plastics or analog, so it has the bending flexibility of preventing, even at it during with sharp bend, it is tired that conductive strips 18 itself yet can not rupture and become.
One side surface of conductive strips 18 (in Fig. 4, the surface of the conductive strips 18 that contact with combination with decorative surfaces (sprayed surface) 14 and ostentatious rear surface (covering the surface) 15 generations) is that composition surface and bonding agent are coated on this composition surface.
This bonding agent has electric conductivity.In other words, electrically conducting adhesive is coated on the composition surface of conductive strips 18.Therefore, be bonded on the object with electric conductivity when conductive strips 18, the stock of this object and conductive strips 18 is electrically connected by electrically conducting adhesive.
The opposite side surface of conductive strips 18 (in Fig. 4, the surface of the conductive strips 18 that do not contact with lower plate 4) is communicated with composition surface gradually, because as mentioned above, the stock of conductive strips 18 itself has electric conductivity.Therefore in conductive strips 18, surface on the composition surface and composition surface facing surfaces have the electric conductivity that strides across these two surfaces gradually.
As shown in Figure 4, conductive strips 18 are bonded on the lower plate 4 from inside to outside.In other words, conductive strips 18 are bonded on the lower plate 4 from ostentatious rear surface (covering the surface) to combination with decorative surfaces (sprayed surface) 14.
For more specific, on ostentatious rear surface (covering the surface) 15, conductive strips 18 are bonded on the surface that is applied with mask and tool electric conductivity (covering the surface).Simultaneously, on combination with decorative surfaces (sprayed surface) 14, conductive strips 18 engage in the scope than lower part that can sufficiently cover combination with decorative surfaces (sprayed surface) 14, in other words, and in the scope of a part of combination with decorative surfaces (sprayed surface) 14 that contacts with main body 2.
By this way, conductive strips 18 are bonded on the ostentatious rear surface (covering the surface) 15 of lower plate 4, thereby conductive strips 18 are folding also being bonded on the conductive component fixed part 17 on the end of lower plate 4.By this simple operation, conductive component 5 is formed at on/off-type panel 1 and main body 2 at an easy rate and produces on the part (conductive component fixed part 17) that contacts, and conductive component 5 is communicated on the conductive surface of the bad radiation that is used for preventing on/off-type panel 1.
Here, mask the time also is applied on the rear surface of upper plate 3 of on/off-type panel 1 in spraying, therefore form conductive surface there, as mentioned above, two conductive surfaces of the ostentatious back of lower plate 4 and upper plate 3 produce and contact, in other words, the conductive surface of the conductive surface of upper plate 3 and lower plate 4 has conduction.Consequently, couple together for covering conductive surface and the conductive component 5 that whole on/off-type panel 1 forms.
Here, by using the conductive strips 18 of conductive component as having anti-bending pliability and having the function that conductive component 5 is linked to each other with conductive surface, have in the end of lower plate 4 when crooked even the shape of lower plate 4 has complicated curved surface and conductive component, this conductive component yet can mechanically not destroy conductive component and make its fatigue along the surface shape curves of lower plate 4.Therefore, this conductive component can be fixed on the lower plate 4 firmly.
By the way, even on the lower plate of being made by the synthetic resin material 4, the conductive strips 18 identical with the example of Fig. 4 also can be used as conductive component 5.In this case, even the material difference of lower plate 4, by carrying out operation simply with the identical mode of the example of Fig. 4, the conductive component 5 that is communicated with the conductive surface of the bad radiation that is used for preventing on/off-type panel 1 can produce formation on the part (conductive component fixed part 17) that contact at on/off-type panel 1 with main body 2 at an easy rate.
Except conductive strips 18,, sheet metal 19 aluminium flake as shown in Figure 5 is formed on the on/off-type panel 1 thereby can being used as conductive component 5.
The transverse section of sheet metal 19 is the arc along the curved surface of the conductive component fixed part 17 of lower plate 4.
Fig. 6 and Fig. 7 represent sheet metal 19 is installed to method on the lower plate 4.
In Fig. 6, sheet metal 19 is fixed on the lower plate 4 by using more than one metallic screw 20.The conductive surface that prevents the bad radiation of lower plate 4 links to each other with conductive component 5 (sheet metal 19) by metallic roll screw 20.
In Fig. 7, sheet metal 19 is fixed on the lower plate 4 by using electrically conducting adhesive 21.More than one aperture 22 is arranged on the contact portion 11 of lower plate 4.Electrically conducting adhesive 21 is coated on the sheet metal 19 by aperture 22 from the conductive surface of lower plate 4.Consequently, the conductive surface that prevents the bad radiation of lower plate 4 links to each other with conductive component 5 (sheet metal 19) by electrically conducting adhesive 21.
The following describes and a kind of pad 6 is installed in method on the main body 2 that contacts with the conductive component 5 of on/off-type panel 1 as conductive component.
Fig. 8 illustrates pad 6 situations about being fixed on the main body of being made by metal material 2.
In Fig. 8, the side of the main body 2 that pad 6 (back is mentioned) are fixed to the upper is sprayed surfaces, and has applied mask when spraying.In other words, expose metal parts from the surface of the main body 2 that engages this pad 6 and this surface has electric conductivity.
In Fig. 8, pad 6 (conductive components) are made by organism such as rubber or analog, this organism and conductive materials such as graphite with analog blend be in the same place.
Therefore, the stock of pad 6 itself has electric conductivity.
A surface of pad 6, that is, the surface that contacts with main body 2 scribbles electrically conducting adhesive 23.Consequently, pad 6 is communicated with the conductive surface of the bad radiation that is used for preventing main body 2.
Fig. 9 represents to fill up the situation on 6 shaded portions 24 that are fixed to main body 2 (by applying the metal parts exposed portions serve that mask forms when the spraying).
At pad 6 when being fixed on the main body 2, the periphery of shaded portions 24 than the periphery of pad 6 more in the inner part, so the metal material of shaded portions 24 can not directly be seen.
By the way, have a kind of method as shown in figure 10, it can be used as pad 6 is fixed to another method on the shaded portions 24 of main body.
In Figure 10, the two ends of pad 6 are fixed on the shaded portions 24 by non-conductive bonding agent 25, and the core of pad 6 directly contacts with the metal material of shaded portions 24.
In this case, on/off-type panel 1 contacts with main body 2, and therefore a part of pad 6 but be not that the two ends of pad 6 are compressed in exposing on the metal part of shaded portions 24 can firmly be connected.
More than be this situation of being made by metal material with reference to main body 2, but when the situation that main body 2 is made by the synthetic resin material identical with the above-mentioned upper plate 3 of on/off-type panel 1 and lower plate 4, pad 6 is fixed on the main body 2 in following mode.
Figure 11 represents to fill up 6 situations about being fixed on the main body of being made by the synthetic resin material 2.
The combination with decorative surfaces 26 of main body 2 exposes the basal plane of synthetic resin material or scribbles coating, therefore needless to say, does not have electric conductivity.
Ostentatious rear surface 27 scribbles conductive compound on its whole surface, this surface has become the conductive surface that is used for preventing bad radiation.
By the way, pad 6 not only has electric conductivity but also is opened at on/off-type panel 1 and also plays a part a damping part up to it and time till main body 2 contacts, otherwise when lower plate 4 clashes main body 2, can damage the surface of lower plate 4 or main body 2.In other words, pad 6 plays a part the impact damper (detent) of on/off-type panel 1.Therefore, require pad 6 (conductive components) to have elasticity.
Here, the conductive component that is bonded on the main body 2 is not limited to pad 6, as long as have electric conductivity and elasticity, certainly adopts other parts.
By the parts that use has electric conductivity, the part that has applied the main body 2 of mask in the above has electric conductivity with the part that contacts with lower plate 4 generations.
Equally, by using the rubber-like parts, on/off-type panel 1 is opened till it and main body 2 produces when contacting in use, make on/off-type panel 1 collision main body 2 even applied powerful power, be with 5 to be damaged and to avoid on/off-type panel 1 and main body 2 to be damaged on the lower plate 4 as avoiding conductive component or being bonded on.
Equally, by using the rubber-like parts as conductive component, when conductive strips 5 on being bonded on lower plate 4 and the conductive component on the main surface are in contact with one another, because the conductive component that is positioned on the main surface produces distortion because of elasticity, therefore produced along the recess of lower plate 4 shapes, made the contact area of conductive strips 5 of conductive component on the main surface and lower plate 4 than not having under the flexible situation much bigger at the conductive component on the main surface.
Structure on on/off-type panel 1 and the main body 2 as mentioned above.Therefore, thereby produce when contacting with main body 2, just finished the electrical connection that to mention below when on/off-type panel 1 is opened.
In other words, upper plate 3 and lower plate 4 are communicated with by the conductive surface that is separately positioned on it.In the part of the combination with decorative surfaces (sprayed surface) 14 of the ostentatious rear surface of lower plate 4 (conductive surface) 15 and lower plate 4, the part that contacts with main body 2 is connected by conductive component 5, conductive component 5 and pad 6 are communicated with, in addition, this pad 6 is communicated with the conductive surface of main body 2, and this conductive surface is communicated with zero potential part 13.
In addition, as for saying this electric conductivity, because the conductive surface of the conductive surface of upper plate 3 and lower plate 4 contacts mutually with facing; The conductive surface 15 of lower plate 4 and conductive component 5 engage in the face of ground; Because the width of conductive component 5 can be guaranteed broad, therefore can guarantee that the conduction cross-sectional area of conductive component 5 is bigger; Conductive component 5 contacts mutually with pad 6 with facing, to filling up the material that 6 selections have suitable elasticity, makes that owing to can form recess on pad 6 further enlarging contact area becomes possibility in addition; Because the width of pad 6 can be widened, the resistance of its thinner thickness thereby existence is less equally, therefore can obtain enough electric conductivity; Owing to can guarantee enough electric conductivity when pad 6 engages with the conductive surface of main body 2 with facing, so on/off-type panel 1 and main body 2 are connected in the conduction region of assurance broad.
Can see from above-described, in portable video recorder (portable V TR), collapsible PC and other electronic device, by opening the on/off-type panel in use till it and main body produce when contact, the conductive component that is arranged on the on/off-type panel can contact mutually with conductive component on being arranged on main body with facing.
Consequently, because the electromagnetic noise that the on/off-type panel produces couples together by the zero potential part (ground wire) of broad surface with main body 2, the electromagnetic noise of sending from the on/off-type panel can reduce in a big way, therefore can adopt effective method to prevent this bad radiation of on/off-type panel.
Simultaneously, the present invention is not limited to the above embodiments, can adopt various structures in the scope that does not break away from main points of the present invention.
The invention provides the effect that to be described below.
Because the on/off-type panel has conductive component, this conductive component with main body and be used for preventing the part electric connection that the conductive surface of bad radiation contacts, main body has conductive component, this conductive component has elasticity, this conductive component and the part electric connection that contacts with on/off-type panel and zero potential part (ground wire), open when using the on/off-type panel when it contacts with the main body generation till, the conductive component that is arranged on the on/off-type panel contacts with the conductive component on being arranged on main body is mutual by elastic deformation with facing, the electromagnetic noise that produces in the on/off-type panel passes on the main body by the surface of a broad, and therefore the electromagnetic noise that sends from the on/off-type panel can reduce on a large scale.
Equally, because the conductive component that is arranged on the on/off-type panel has anti-bending pliability, even when conductive component is had to bending, conductive component can not take place yet mechanically damaged and tired situation.Equally, because the conductive component that is arranged on the main body has elasticity, therefore make that conductive component and the contact area between the conductive component on the lower plate on the main body are very big.
With reference to accompanying drawing the preferred embodiments of the present invention have been described, be understood that the present invention is not limited to these specific embodiments, to those of ordinary skill in the art, within spirit of the present invention that does not break away from appending claims and limited or scope, can carry out various improvement and distortion.
