Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection device, and its purpose is to provide a novel connection device using a flexible printed wiring board.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 and 2 are hard printed wiring boards on which electronic components 3 and 4 are mounted and electronic circuits are assembled, and 5 and 6 are the above board 1.
, 2 are electrically conductive and rigid connection terminal members, and 7 is press-fitted into the arc-shaped recesses 5a and 6a of the connection terminal members 5 and 6, respectively, with a cylindrical elastic insulating locking member 8. It is a flexible printed wiring board whose both ends are held and fixed with a soldering iron.

The signal transmission conductive foil 7a of the flexible printed circuit board 7 is pressed against the conductive portions 9 of the connection terminal members 5, 6, as shown in FIG. 9 is connected to the conductive foil 11 on the back side through the soldering part 10 from the through hole 1av2a of the circuit board 1, 2, and is further connected to the conductive foil 11 on the back side.
connected to the electronic circuit above.

In the above embodiment, a part of the connecting terminal member 6 is made into a conductive part 9, and the whole is integrated, but only the conductive part 9 may be taken out and attached as shown in FIG.

In the case of FIG. 4, the locking member 8 is made of a pipe made of an elastic material such as silicone rubber as shown in the figure, so even if the mounting position of each conductive part 9 is slightly shifted, the flexible printed wiring board 7 can be sufficiently mounted. be able to.

Further, as shown in FIG. 5, the entire connecting terminal member 6 may be made of a conductor, or the engaging member 8 may be made of a rigid body and the connecting terminal member 6 may be made of an elastic body.

Furthermore, the engaging member 8 is not limited to a cylindrical or cylindrical shape, and various shapes such as a prismatic shape can be used, and the shapes of the recesses 5a and 6a of the connecting terminal members 5 and 6 are also the same. It is.

As explained above, the connection device of the present invention uses a flexible printed circuit board as a signal transmission line and directly engages with the engaging portion of the connection terminal member to establish an electrical connection. The area of the parts is large, making it possible to make highly reliable connections, and it is also inexpensive and can be easily disconnected by simply removing the locking member during repairs. effect can be obtained.
