This first plain conductor 421 is an earth connection, and metal material 5 is an aluminium foil, and metal level 8 is an aluminium foil, and metal level 8 whole being covered on the insulation material 3, so to reach the preferable effect that prevents Electromagnetic Interference.In addition; The second hot pressing point 72 can be set on metal material 5; This second hot pressing point 72 is arranged on the metal material 5 corresponding to one second plain conductor 422 of the portion of exposing 40; Wherein to be electrically connected at metal material 5, the second plain conductors 422 via the aeolotropic conductive 6 corresponding to the second hot pressing point 72 be an earth connection to second plain conductor 422, and it can reach and be similar to the same ground connection effect of first plain conductor 421.
In the present embodiment; The front end of conductor layer 4 exposes to the last insulating barrier 32 of insulation material 3 to form one first contact portion 44; The rear end of conductor layer 4 exposes to the last insulating barrier 32 of insulation material 3 to form one second contact portion 46; Expose portion 40 between the first contact portion 44 and the second contact portion 46, and the spacing size L1 essence that exposes the distance first contact portion 44 of portion 40 equals the spacing size L2 of 40 distances, the second contact portion 46 of the portion of exposing, so the structure of design can be easy to the enforcement of automatic mass.In addition, on metal material 5 except being provided with the first hot pressing point 71 and the second hot pressing point 72, also can be according to client's demand, the setting of extra other hot pressing point of increase.
In addition; In order to let bus-bar construction 1 have the wire jumper function, as shown in Figure 5, can on this second plain conductor 422, be provided with one and block portion 424; This blocks portion 424 and makes between the first contact portion 44 and the second contact portion 46 of second plain conductor 422 and present off state; This moment, 421 conducts of first plain conductor provided the usefulness of power supply, so second plain conductor 422 also is a power line, the overlap joint that transmits the electric current process metal material 5 of coming in from first plain conductor 421 can be sent to second plain conductor 422; And be provided with insulating cement (do not illustrate) between metal level 8 and the metal material 5 this moment, so that no longer include the relation that electrically conducts between metal material 5 and the metal level 8.
Please with reference to Fig. 6 to Fig. 9; The manufacturing approach 9 of bus-bar construction provided by the invention, the manufacturing approach 9 of this bus-bar construction comprise provides a flexible flat cable 90, and wherein flexible flat cable comprises insulating barrier on, a conductor layer and insulating barrier once; Last insulating barrier is provided with several openings; Those openings are equidistantly arranged along the length direction of last insulating barrier, and conductor layer comprises several plain conductors that are arranged in parallel, and last insulating barrier, conductor layer and following insulating barrier form this flexible flat cable via a zygonema processing procedure; As shown in Figure 7; Conductor layer is provided with the portion of exposing and exposes to insulating barrier via opening, and those openings comprise that several connect opening 902 and cut opening 901 with several, and arbitrary opening 902 that connects cuts between the opening 901 wantonly two; Each that utilize that an aeolotropic conductive (ACF) is arranged at flexible flat cable with a metal material connects on the opening 92, and is as shown in Figure 8, and wherein the portion of exposing of metal material and conductor layer is up and down and is oppositely arranged, and aeolotropic conductive is located between the portion of exposing and the metal material; Carry out a heat-press step on aeolotropic conductive 94; As shown in Figure 9; Wherein heat-press step is chosen in corresponding to heating and pressurizing is to form one first hot pressing point on the metal material of one first plain conductor of the portion of exposing, and first plain conductor is electrically connected at the metal material via the aeolotropic conductive corresponding to the first hot pressing point; Form a metal level in the insulation material on 96, wherein metal level is electrically connected at the metal material; And carry out a cutting step and cut on the opening 98 in those of flexible flat cable, flexible flat cable is cut into several bus-bar constructions, so can make bus-bar construction with grounding function.
The another kind of selection is; If will make bus-bar construction have the wire jumper function; Can carry out heat-press step on aeolotropic conductive 94 o'clock; Increase following steps in addition: be chosen in corresponding to heating and pressurizing is to form one second hot pressing point on the metal material of one second plain conductor of the portion of exposing, second plain conductor is electrically connected at the metal material via the aeolotropic conductive corresponding to the second hot pressing point; Carry out again afterwards opening circuit step on second plain conductor, block portion so that form one on second plain conductor.At this moment, reach the purpose that electrically conducts via the metal material between second plain conductor and first plain conductor.Then form again a metal level in the insulation material on 96; This moment, metal level was not electrically connected at the metal material; The last cutting step that carries out equally again cuts on the opening 98 in those of flexible flat cable; Flexible flat cable is cut into several bus-bar constructions, so can make bus-bar construction with wire jumper function.
What deserves to be mentioned is; Because several openings of last insulating barrier are equidistantly arranged along the length direction of last insulating barrier; So help when the zygonema processing procedure and conductor layer and down insulating barrier form this and have the flexible flat cable of opening; More help using the pressing mode that aeolotropic conductive and metal material are attached at connecting on the opening of flexible flat cable afterwards; So making things convenient for automation to produce in a large number, and the bus-bar construction made from this kind mode, it is equal apart from the big or small essence of the spacing between the contact portion of its rear and front end that it exposes portion.It is understandable that each in several openings in the present embodiment connects opening and each cuts opening interleaved arrangement setting.
In sum; The manufacturing approach of bus-bar construction of the present invention; It just offers opening so that the part conductor layer is exposed when being utilized in the flexible flat cable of making existing use; With pressure programming aeolotropic conductive and metal material are attached on the opening of flexible flat cable more afterwards, then carry out the hot pressing processing procedure and make earth lead be electrically connected at the metal material, so just can form bus-bar construction with electromagnetic wave shielding effect and grounding function.Because bus-bar construction of the present invention is structurally very simple, produces in a large number so on processing procedure, be easy to reach automation, can effectively reduce production time and cost.
The above for the person of ordinary skill of the art, can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection range of claim of the present invention.
