Printed wiring board connection structure
First Claim
1. A connection structure for a printed wiring board for electrically connecting a FPC and a printed wiring which is electrically connected to this FPC, wherein:
- said FPC comprises a board-shaped substrate and has an exposed conductor part which can be elastically deformed in the thickness direction;
said exposed conductor part has an exposed surface on a surface of said substrate onto which a plurality of conductors is placed;
said conductor comprises a protrusion on a surface which protrudes from said substrate;
said printed wiring board is formed by stacking a plurality of base plates and comprises an insertion opening into which said FPC is inserted in an edge surface parallel to the stacking direction of said base plates and a plurality of through-hole ports provided on an inner wall surface of said insertion opening; and
said protrusions of said FPC is connected to said through-hole port of said insertion opening and pressed thereto when said FPC is inserted into said insertion opening of said printed wiring board.

Abstract
A connection structure for a printed wiring board which enables high density integration is provided. A FCP 2 includes an exposed conductor part 2A including an insulating substrate 22 and a reinforcing plate 24 stacked with this substrate 22 via an elastic member 23. In the exposed conductor part 2A, conductors 21 each having a protrusion 20 formed on a surface is placed on the insulating substrate. The exposed conductor part 2A can be elastically deformed in the thickness direction in which the substrate 22, the reinforcing plate 24 and the like are stacked. A printed wiring board 1 is constructed by stacking an inner layer board 10 and a first outer layer board 11 and a second outer layer board 12 which sandwich this inner layer board 10. A notched groove 10A is formed on the inner layer board 10, and an insertion opening 10B is formed. Through-hole ports 11 which appear on the notched groove 10A side is placed on the first outer layer board. When the FPC 2 is inserted into the insertion opening 10B, the protrusion 20 of the FPC 2 fits with the through-hole port 11A from within insertion opening 10B and presses thereto.

4. A connection structure for a printed wiring board for electrically connecting a FPC and a printed wiring which is electrically connected to this FPC, wherein:
-
said FPC has an exposed conductor part comprising a board-shaped substrate formed from insulating material and a reinforcing plate which is stacked in close contact with this substrate;
said exposed conductor part has an exposed surface on a surface of said substrate onto which a plurality of conductors are placed and is inserted into the printed wiring board by contacting an insertion jig closely to said reinforcing plate and;
said conductor comprises a protrusion on a surface which protrudes from said substrate;
said insertion jig comprises a lead part which is inserted into said printed wiring board and a locking part for locking said FPC;
said lead part is formed from an elastic material having the same width as said exposed conductor part of said FPC, is bent in the thickness direction which is the direction said substrate and said reinforcing plate of said exposed conductor part is stacked to form a crease which extends in the direction perpendicular to the thickness direction;
said locking part comprises a pair of locking pieces for locking said FPC;
said printed wiring board is formed by stacking a plurality of base plates and comprises an insertion opening into which said FPC is inserted on an edge surface parallel to the stacking direction of said baseplates and a plurality of through-hole ports provided on an inner wall of this insertion opening; and
said protrusion of said FPC is connected to said through-hole port of said insertion opening and pressed thereto when said FPC is inserted into said insertion opening of said printed wiring board.
