Abstract:
A step portion is disposed at the periphery of a position where the adhesive is applied so that a front end of a needle for ejecting the adhesive comes in contact with the step portion. A passage is formed in the step portion so as to introduce the adhesive ejected from the front end of the needle to the position.
Abstract:
The present invention provides a simple structure for connecting a flexible printed circuit board to a printed circuit board in which when connecting a flexible printed circuit board to a printed circuit board, the positioning thereof can be made easily, the connection therebetween can be made smoothly and rigidly, and further the assembling time can be reduced. Patterns, on a flexible printed circuit board and a printed circuit board are aligned and connected with each other by soldering. An elongate hole is formed in the vicinity of and along the edge portion in a connecting part of the printed circuit board, and two rectangular holes communicating with the elongate hole are formed at both longitudinal ends of the elongate hole, while two notches for controlling insertion depth are provided at opposing ends of the connecting edge of the flexible printed circuit board. The leading edge portion of the flexible printed circuit board, which is left between the cut portions, is bent downward, and the bent portion is inserted into the elongate hole and the rectangular holes of the printed circuit board to position the flexible printed circuit board, and then the patterns, respectively located on the flexible printed circuit board and the printed circuit board, are connected by soldering.

The present invention provides a simple connecting structure of flexible printed circuit board to printed circuit board in which when connecting a flexible printed circuit board to a printed circuit board, the positioning thereof can be made easily, the connection therebetween can be made smoothly and rigidly, and further the assembling time can be reduced. Patterns 6 and 7, respectively, on a flexible printed circuit board 4 and a printed circuit board 1 are to be aligned and connected with each other by soldering. An elongate hole 2 is bored in the vicinity of and along the edge portion 1a in a connecting part of the printed circuit board 1, and two rectangular holes 3 communicating with the elongate hole 2 are formed toward the opposite direction of the edge portion 1a in both longitudinal end portions of the elongate hole 2, while two cut portions 5 for controlling insertion depth are provided on both ends of the connecting edge of the flexible printed circuit board 4. The leading edge portion 4a of the flexible printed circuit board 4, which is left between the cut portions 5, is bent downward, and the bent portion is inserted into the elongate hole 2 and the rectangular holes 3 of the printed circuit board 1 to position the flexible printed circuit board 4, and then the patterns 6 and 7, respectively, on the flexible printed circuit board 4 and the printed circuit board 1 are connected by soldering 10.
