Description

Soft Circuit Board Union

Technical field

The utility model relates to a kind of Soft Circuit Board Union, refer to especially by integrated shield shell the Soft Circuit Board Union of extended earth terminal.

Background technology

Flexible circuit board (claiming soft board again), its base material is soft plastic insulating layer, has deflection, gently, but quantity-produced characteristic, the processing procedure difficulty is than the hardboard height, purposes the most in one's early years is in high-tech electronic instrument such as military affairs, fields such as space flight, common now purposes such as LCD, notebook computer, clamshell phone, digital camera etc., because the flexible circuit plank has used very extensively now, little of wrist-watch, calculator, big to LCD, LCD TV etc., its application product that is seen everywhere almost in life, and miniaturization along with board area, with each circuit function modularization processing procedure, so between each circuit module, need Soft Circuit Board Union to be connected to each other, make a general survey of existing now connector, as propose the novel patent application of LCD connector fastening structure () on October 30th, 2003, and obtain bulletin on October 01st, 2004 and check and approve patent, the TW notification number is M245635 number, see also shown in Figure 8, three-dimensional exploded view for existing Soft Circuit Board Union, it comprises metal-back A, insulator B, earth terminal C and signal terminal set D form, wherein earth terminal C and signal terminal set D are assembled in the insulator B, continuous insulator B is assembled in the metal-back A forms combination, there is following defective in right above-mentioned Soft Circuit Board Union really when using:

Existing insulator B is when installing signal terminal set D, need one formality again to install earth terminal C in addition, so, make insulator B need offer a plurality of slotted eyes and wear the location for earth terminal C and signal terminal set D, but the connector volume develops towards the direction of miniaturization gradually, the terminal volume of being accommodated in its insulator B is also more small, and make between terminal and the terminal apart from also more intensive, make insulator B difficult more when offering slotted eye, installing also easy fitted not during terminal, and need two road formalities to assemble, and then make product defect rate raise easily, also increase the time cost of assembling; Moreover, earth terminal C and signal terminal set D are assembled in the insulator B simultaneously, its distance is very close, when using, is easy to generate mutual interference, and cause the effect of ground connection to reduce, and earth terminal C also must contact really with metal-back A, noise could be derived, but as if the error because of size, make earth terminal C can't contact easily, and cause the effect forfeiture of ground connection with metal-back A.

Moreover, please continue to consult shown in Figure 9, three-dimensional exploded view for existing another form of Soft Circuit Board Union, it comprises insulating base frame E, loam cake F and bottom G constitute, wherein this insulating base frame E coats clamping mutually with loam cake F and bottom G, so, when assembling, must can finish by the multiple tracks number of assembling steps, promptly insulating base frame E outside must be divided into metal shell loam cake F and bottom G two partly when the clad metal housing, and the program of processing separately, among the process of processing, the dimensional tolerance when loam cake F partly must pay special attention to combine with the combination of bottom G is if tolerance is excessive accidentally simultaneously, cause loam cake F and bottom G to assemble smoothly easily, also reduce production efficiency easily, must come separate machined to make by two groups of moulds simultaneously, and then whole manufacturing cost is improved.

So, how to solve the above problems and defective, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
