US 4,380,119 A · Method of making an electrical connector assembly

Abstract

An improved electrical connector assembly (10) is disclosed. The assembly is especially adapted for engagement with a printed circuit board (76) having electrical circuits formed on both sides thereof. The assembly includes a body (12) of molded dielectric material having four spaced rows of passages (24) extending therethrough from a front face (26) to a rear face (28) of the body. The assembly also includes brush wire electrical contacts (14) each received in its respective passage. Each of the contacts has a cylindrical body portion (62) and an elongated tail (64) attached to one end of its body portion. The ends (72) of the termination portions extend beyond the rear face and form two spaced straight line rows adapted to receive the printed circuit board therebetween. The ends (63) of the body portions opposite their respective termination portions comprise four spaced apart, straight line rows of body portion ends. The connector assembly is thereby adapted to mate with a square grid brush contact connector at the four rows of body portion ends.

Dependent claims

A method of making an electrical connector assembly including a body of dielectric material having a plurality of passages extending therethrough from a front face to a rear face and further including a plurality of electrical contacts, each electrical contact being adapted to mount within one respective passage and each having a body portion at one end thereof and a termination portion extending from the body portion, the steps of method comprising:

molding the body to form the passages, each of said passages forming on each respective face an array of spaced-apart openings disposed in straight line rows, the front face array of openings describing a grid comprising four spaced-apart rows and the rear face array of openings describing a grid comprising two spaced-apart rows,
inserting the contacts into their respective passages so that the termination portions extend beyond the rear face of the body and the body portions of the contacts are adjacent the front face, and
bending the termination portions of the contacts so that the ends of the termination portions extending beyond the rear face form two rows.

A method of making an electrical connector assembly for use in making an electrical interconnection with a printed circuit board, the board being of the type comprising a planar edge including electrical circuit paths formed on both sides thereof, the electrical connector assembly including a body of molded dielectric material having a plurality of passages extending therethrough from a front face to a rear face and further including a plurality of electrical contacts, each electrical contact being of the type having a body portion at one end thereof and adapted for connection in electrical circuit relationship with another electrical contact and a termination portion extending from the body portion and adapted for connection in electrical circuit relation with respective of said electrical circuit paths, the steps of the method comprising:

molding first and second sets of passages so as to provide said plurality of passages, each passage having a medial position between the front and rear faces and including an elongated channel portion extending inwardly along a first longitudinal axis from its opening on the front face to the medial position and a groove portion extending inwardly along a second longitudinal axis from the rear face to the medial position so as to be in communication with the channel portion, each second longitudinal axis being disposed at an acute angle to its first longitudinal axis and the first and second sets of passages, respectively, including their second longitudinal axes being coparallel
inserting the contacts into their respective passages so that the body portions are received in respective of said channel portions and the termination portions are received in respective of said groove portions and extend beyond the rear face of the body, and
bending the termination portions of the contact so that the ends of the termination portions extending beyond the rear face form first and second parallel and spaced apart rows of contact arms for making interconnection with the printed circuit board circuit paths inserted therebetween.
