Abstract:
A connector element or plug for use in circuit boards is a double-ended plug with an interconnecting shank between the larger head portion at one end and a smaller head or retainer portion at the other end, and this plug is positioned in a hole in a circuit board with the larger head overlying one surface of the board and a circuit thereon, and with the retainer extending beyond the hole at the opposite side of the board to hold the plug in position. The connector element establishes an electrical connection from the circuit contacted thereby to another circuit or to another connector element in another circuit board overlying the first board. Alternatively, the connector element has a central recess to receive a connector pin from a circuit external to the circuit board as, for example, a pin in a dualin-line package or a contact on a leadless IC package and makes a connection from said pin to the circuit on the board contacted by the connector element.
