The ground connection of above-mentioned complete machine realizes by the ground connection ear of FPC that generally in the prior art, the ground connection ear of this FPC adopts design as shown in Figure 1.
The inventor is realizing by in the process of ground connection ear ground connection, finds that the ground connection ear is easy to rupture and tear in the process of using.
Summary of the invention
The utility model embodiment provides a kind of FPC ground connection ear, makes the ground connection ear be not easy fracture and anti-bending in the process of using.
For achieving the above object, the utility model adopts following technical scheme:
A kind of FPC ground connection ear comprises FPC plate and the coverlay that pastes on the FPC plate; Also comprise: be arranged on the dew copper district in the FPC plate, described dew copper offset has the spacing that pre-sets from the both sides up and down of described FPC plate, is covered with described coverlay on the described spacing.
Compared with prior art, to reveal the copper district in the utility model and be arranged in the FPC plate, and apart from the both sides up and down of described FPC plate the spacing that pre-sets be arranged, this kind design makes reveals the protection that the copper district is subjected to the FPC plate, be difficult for being fractureed or tearing, make the ground connection ear not easily damaged; And on the spacing on the both sides up and down of described dew copper district and FPC plate, be coated with coverlay, make described dew copper district further be subjected to the protection of this coverlay, make the ground connection ear of this FPC plate in the process of using, be not easy fracture and anti-bending.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of FPC ground connection ear in the prior art;
Fig. 2 is the structural representation of FPC ground connection ear among the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of FPC ground connection ear, and as shown in Figure 2, this FPC ground connection ear comprises FPC plate 1 and the coverlay 2 that pastes on the FPC plate; Also comprise: be arranged on the dew copper district 3 in the FPC plate, there is the spacing that pre-sets on the both sides up and down of the described FPC plate 1 of described dew copper district 3 distances, and are covered with described coverlay 2 on the described spacing.The described distance that pre-sets is provided with according to actual needs, and the utility model embodiment does not limit this.
Compared with prior art, to reveal the copper district in the utility model and be arranged in the FPC plate, and apart from the both sides up and down of described FPC plate the spacing that pre-sets be arranged, this kind design makes reveals the protection that the copper district is subjected to the FPC plate, be difficult for being fractureed or tearing, make the ground connection ear not easily damaged; And on the spacing on the both sides up and down of described dew copper district and FPC plate, be coated with coverlay, make described dew copper district further be subjected to the protection of this coverlay, make the ground connection ear of this FPC plate in the process of using, be not easy fracture and anti-bending.
Further, described FPC plate comprises upper and lower surface, for described ground connection ear better is grounded, described dew copper district can be arranged in the one side in the upper and lower surface of described FPC plate, also can be in the upper and lower surface of described FPC plate described dew copper district all is set; When described dew copper district all is set in the upper and lower surface of described FPC plate, rupture, need to be staggered mutually in the described position that is provided with that is arranged on the dew copper district on two sides in order to prevent this ground connection ear stress from concentrating.
Further, for the ground connection ear that makes described FPC ground connection preferably, the top of the end in described dew copper district and described ground connection ear is tangent, and the other end is positioned at described FPC ground connection ear; And the other end in described dew copper district can for but be not limited to arc, when the described FPC ground connection of bending ear, arc has well opens property, can guarantee that described dew copper district is not fragile.Wherein the radian of this arc can specifically be provided with according to actual needs, and this use new embodiment does not limit this.
The use of described FPC ground connection ear for convenience, the length in described dew copper district is smaller or equal to the length of FPC ground connection ear.
Described dew copper district is printed with conducting metal, so that realize the ground connection of FPC plate; Further prevent that for example this ground connection ear is in the process of using, since bending make described FPC ground connection ear dew copper district fracture or tear, described conducting metal is the conducting metal of anti-bending, make the conducting metal that reveals the copper district have the curved property of folding preferably, thereby guarantee that this FPC ground connection ear is not fragile in the process of using.
To reveal the copper district among the utility model embodiment and be arranged in the FPC plate, and apart from the both sides up and down of described FPC plate the spacing that pre-sets be arranged, this kind design makes reveals the protection that the copper district is subjected to the FPC plate, is difficult for being fractureed or tearing, and makes the ground connection ear not easily damaged; And on the spacing on the both sides up and down of described dew copper district and FPC plate, be coated with coverlay, make described dew copper district further be subjected to the protection of this coverlay, make the ground connection ear of this FPC plate in the process of using, be not easy fracture and anti-bending.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of described claim.
