Abstract
The invention relates to a conjunction method which firstly provides a flexible flat cable. Adhesive agent is arranged on one side of the flexible flat cable and a plurality of separated first contacts are arranged on the other side of the flexible flat cable corresponding to the adhesive agent; then a substrate provided with a plurality of second contacts corresponding to the first contacts is provided; the adhesive agent is melted and filled between contacts by heating for the first time and the first contacts and the second contacts are mutually melted and combined by heating for the second time. By adopting the method, the flexible flat cable and the substrate can not only be electrically connected with each other rapidly, and short circuit between contacts can also be avoided by filling the contact gap with the adhesive agent.
Description
Technical field
The present invention is relevant for soft bar wire connection method and connected structure thereof, refer to especially a kind ofly can constitute the electric connection of flexible flat cable and substrate fast, and utilize the adhesive agent filling between each contact, and guarantee between each contact not can short circuit soft bar wire connection method.
Background technology
(flexible flat cable FFC) is the connecting line structure of a kind of frequent use in electronic installation to soft arranging wire, and in general, it for example is insulating barrier such as polyester film that the pin of typical soft arranging wire is coated with outward usually.The characteristic of soft arranging wire is to have goodish pliability, therefore can provide suitable wiring in narrow space.With the photocopier is example, moves around promptly to be connected with circuit board by soft arranging wire with the support (carriage) that carries out scanning document.Altogether he the application that also can see soft arranging wire such as is equipped with in (printer, scanner, mobile computer etc.), electronic system (brush barcode machine) and the LCD at consumption electronic products, computers such as shooting with video-corder projector.
Please refer to Fig. 1, Fig. 1 shows the organigram of traditional circuit-board and soft arranging wire.One circuit board 10 has a main body 101 and a plurality of lead 102, an end of lead 102 can be separately with main body 101 on different circuit units connect.One soft arranging wire 11 has a plurality of pins 112, and pin 112 outsides are coated with a bendable plastic insulating barrier 111, the pin 112 of exposed portions serve.Pin 112 is connected with lead 102 by scolding tin 12, so that the particular electrical circuit conducting on soft arranging wire 11 and the circuit board 10, as shown in Figure 2.
Please join shown in Fig. 3 A and Fig. 3 B, the enlarged drawing that Fig. 3 A pin 112 is connected by the lead 102 on the main body 101 of scolding tin 12 and circuit board 10, the sectional drawing of 1 '-1 ' tangent line on Fig. 3 B Fig. 3 A can be known and see that scolding tin 12 is surrounded on being connected with the lead 102 with pin 112 belows of pin 112 on every side.
Because the thin thickness of each pin 112 of traditional soft winding displacement 11 and the quite little cause of distance to each other, the too much scolding tin 12 of quantity can touch the pin 112 of both sides, cause 112 short circuits each other of pin, therefore the method for tradition scolding tin 12 on around the pin 112, normally pin 112 is clamped with corresponding lead 102 earlier so that after it contacts with each other with the anchor clamps (not shown), provide scolding tin 12 in the wherein side of pin 112 near the position of insulating barrier 111, and the angle of switch fixture so that scolding tin 12 around around the whole pin 112.Such method is quite consuming time, though can avoid pin 112 short circuits, scolding tin 12 quantity that may cause 102 in pin 112 and lead cause conductivity to each other not good very little.
Summary of the invention
In view of this, main purpose of the present invention can constitute the electric connection of flexible flat cable and substrate fast, and utilizes the adhesive agent filling between each contact, and guarantee can short circuit between each contact.
For reaching above-mentioned purpose, joint method of the present invention provides flexible flat cable earlier, its flexible flat cable one side is provided with adhesive agent, and in the in addition side of adhesive agent with respect to flexible flat cable, be provided with first contact of plural space, substrate is provided again, its substrate is provided with plural number second contact relative with first contact, utilizing heats for the first time makes adhesive agent fusing filling between each contact, impose again and heat for the second time, first and second contact is melted mutually and engage, can constitute the electric connection of flexible flat cable and substrate.
