Electrical connector

Abstract

An electrical connector including an insulator and a number of contacts for mounting on a substrate such as a printed circuit board. As disclosed, the electrical connector includes an elongated insulator block carrying contacts in the form of pins, an end of each of which is received in a printed circuit board aperture to be soldered to the printed circuit board. The elongated insulator block further includes a series of holes, each intermediate an adjacent pair of contacts of the connector, precisely located relative to the contact locations, to facilitate positioning the connector for insertion of the pins into a printed circuit board. The insulator block is notched adjacent each of the holes to facilitate breaking the connector to a desired length, and hence containing a desired number of contacts. The insulator block further has generally semi-cylindrical indentations at each of its ends. To mechanically secure the electrical connector to a printed circuit board, prior to soldering of the contact pins thereto, a peg is inserted through one of the holes in the insulator into gripping engagement with the walls of an aperture in the printed circuit board.
