Wait. In use, the flexible cable itself is not directly connected to the circuit board, but is electrically connected through a connector fixed to the circuit board, and such a connector is generally referred to as a flexible cable connector. However, most of the general electronic components are still soldered to the printed circuit board (PCB). The traditional circuit board processing method is that there are holes and solder joints of the parts on the printed circuit board, and the pins pass from the part surface through the printed circuit board to the copper foil surface. The solder is used to fix the pins and solder joints of the parts. And conductive. The Surface Mount Technology (SMT) board will have copper foil on the part surface and no solder joints. The SMT part pins are directly attached to the PCB, and the solder is fixed and guided to 200937756. In such a manufacturing process, it is easy to cause the problem of empty welding due to the phenomenon of eating tin. In view of the various problems of the prior art, the inventors have proposed a flexible circuit board connector based on years of research and development and many practical experiences, as an implementation and basis for improving the above disadvantages.

For the sake of understanding, the same components in the following embodiments are denoted by the same reference numerals. Please refer to the first figure and the second figure at the same time, which is an exploded view of the components of the flexible circuit board connector of the present invention and an external view of the component combination. In the figure, the flexible circuit board connector 1 comprises a flexible cable 11, an insulative housing 12, a first colloid, a plurality of signal terminals 14, a cover 15, and a plurality of second colloids 16. The insulative housing 12 has an accommodating space 121 and a plurality of terminal cavities 122. The first colloid (not shown) is disposed under the flexible cable 11 to connect the flexible cable 11 to the accommodating space 121. The signal terminals 14 are arranged in the terminal insertion slots 122. Each of the signal terminals 14 has an elastic insert 141 and an extension member 142. The cover 15 has a plurality of insertion holes 151. When the cover 15 is assembled When the main body 12 is insulated on the 200937756, each elastic insert 141 can protrude from the plug hole 151, and a second colloid 16' is disposed above the cover 15 for the flexible circuit board connector 1 to be more firmly bonded to the printed circuit board. (Not shown in the figure). Wherein, the two ends of the insulative housing 12 extend and hold the arm 123. When the flexible circuit board connector 1 is bonded to the printed circuit board, the latching arms 123 at both ends of the insulative housing 12 can be directly crimped onto the printed circuit board. The predetermined hole 'makes the flexible circuit board connector 1 card 0 to the printed circuit board' and is electrically connected to the board termination point on the printed circuit board.

In Figures 4A and 4B, the combined flexible circuit board connector is decomposed to compare the difference between the components before assembly (as shown in the first figure) and after assembly, and the biggest difference is that Signal terminal 44. In Fig. 1, the signal terminal 14 has an elastic insert 141, an extension member 142, and a tape, and in Fig. 4A, the assembled flexible circuit board connector has a signal terminal 44 that is broken by the tape. The process of separation, therefore, the terminal of the Q-number terminal 44 has only a portion having the elastic insert 442 and the extension 441. In addition, when the flexible circuit board connector is bonded to the printed circuit board by the second adhesive 46, the holding arms 423 at both ends of the insulating body 42 can engage the flexible circuit board connector with the printed circuit board. Furthermore, since the two ends of the insulative housing 42 are respectively provided with a hole plug 424, the terminal embedding groove further has a plurality of welding posts 425. Therefore, when the FFC cable 41 and the insulative housing 42 are joined by the first adhesive 43 (as shown in FIG. 4B), the positioning holes 411 on both sides of the FFC cable 41 can be sleeved to the plugs at both ends of the insulative housing 42. 424. The cover body 200937756 45 further includes a slot 452 and a welding hole 453. The slot 452 of the cover body 42 is overlapped with the positioning hole 411 on both sides of the FFC cable 41, and is inserted into the hole plug 424 at both ends of the insulating body 42. The fusion hole 453 is sleeved to the fusion column 425, and then the fusion column 425 and the fusion hole 453 are integrally integrated by a high temperature welding step, so that the cover 45 and the insulating body 42 form a firm bond. In the fifth figure, the flexible circuit board connector of the present invention covers the two-stage adhesive after the cover 45 is used, and then the flexible circuit board connector can be turned over one hundred and eighty degrees, and then directly inserted by the holding arm 423. The hole 51 in the preset printed circuit board (PCB) is engaged with the pad on the printed circuit board 50, thereby solving the problem that the conventional flexible circuit board connector has many pins. The problem of arching and poor contact makes the flexible circuit board connector of the present invention can be surely affixed to the printed circuit board (PCB), and the height of the two can be effectively reduced. The above is intended to be illustrative only and not limiting.
