ABSTRACT:
A connection pin is used to electrically connect a first pattern and a corresponding second pattern of at least one set of patterns formed in a matrix board and crossing one over the other. The connection pin is inserted into a through-hole formed in the matrix board. The through-hole extends through the first and second patterns at an intersection of the first and second patterns. The connection pin includes a fitting portion, abutting portion, and electrical conductor between the fitting portion and abutting portion. The conductor generally extends along the through-hole and has a pair of resiliently deformable ends. One deformable end is mounted to the fitting portion and the other deformable end is mounted to the abutting portion. When the connection pin is inserted into the through-hole, the abutting portion abuts the extreme end of the through-hole. A further insertion of the connection pin causes the fitting and abutting portions to move toward each other. This causes the conductor to resiliently deform so that the conductor laterally extends into electrical contact with the first and second patterns. The connection pin may include a plurality of conductors with an insulating material between adjacent conductors in order to accomplish electrical connection between the first and second patterns of a plurality of sets of patterns.
