CONNECTOR PIN UNIT FOR BREADBOARD

PROBLEM TO BE SOLVED: To provide a pin connector for a breadboard that changes a connection pin from 100 to 300 mil pitches and at the same time corresponds to an arbitrary number of pins that can be connected. SOLUTION: A connector pin unit 20 for a breadboard consists of a nearly rectangular parallelepiped-shaped case 1 that is filled with synthetic resin and has the width, length, and depth dimensions of X=9.8 mm, Y=5 mm, and Z=2.5 mm, respectively, connection pins 3 and 4 that vertically project from an upper surface 1a of the case 1 in parallel while the distance P1 between the centers of the pins is set to 100 mil, and connection pins 5 and 6 that correspond to each of the connection pins 3 and 4, are subjected to conduction inside the case and at the same time vertically project from a lower surface 1b of the case 1 in parallel while the distance P3 between the centers of the pins is set to 300 mil. In the connector pin unit 20 for the breadboard, three of recessed and projection parts 8 and 9 with dimensions and a shape for closely fitting to a position corresponding to two side surfaces 1c and 1d where the case 1 opposes are provided, and an interlock means 7 that detachably interlocks to a connector pin unit 1' for other breadboards of the same kind is provided.
