Abstract: An apparatus for simultaneously forming a radial collar (16) medially of an axial electrical contact of the type having a forward shoulder portion (14) and a rearward termination portion (18) and assembling a plurality of straight wires (24) into an axially passage (22) coaxially disposed with the shoulder portion, the apparatus being characterized by: a generally cylindrical male member (36) having a cylindrical hole (38) sized to receive and mount the termination portion (18); and a receiving member (46) including a collar portion (47) having an inwardly extending aperture (48) sized to receive the shoulder portion (14), the aperture having a cross-section slightly less than the outer diameter of the shoulder portion, the receiving member (46) being spaced from the male member (36), the axis of the hole (38) and the aperture (48) being generally coaxial with one another, and the members being adapted to be driven towards one another whereby the receiving member (46) simultaneously squeezes both radially and

Abstract: An improved method of making a retention collar (16) medially of an elongated electrical contact (10) of the type including a shoulder portion (14) and a termination portion (18), the shoulder portion (14) being formed with an axial passage (22) sized to secure several straight conductive wires (24) for mating. The individual wires are inserted into the passage and the shoulder portion then swaged (i.e., squeezed) by a pair of movable dies (36, 46) in an axial direction along the entire length of the passage so that an outer wall portion of the shoulder portion is pushed axially rearwardly and radially outwardly to thereby form the retention collar (16) and also pushed radially inwardly to thereby secure the wires within the passage.

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.

Abstract: An improved electrical contact (10) for an electrical connector is disclosed. A first version of the contact comprises an elongated deep-drawn holder (11) having an axial holder passage (14) and an enlarged shoulder (12). The contact also includes a plurality of axially aligned electrical conducting fine wires (50) assembled together in a brush wire bundle. An elongated deep-drawn sleeve member (40) having an axial passage (46) extending therethrough is positioned over the holder to transform the first version into a second version of the contact. An intermediate flange (20) of the holder disposed rearward the shoulder is bent radially inwardly from the inner surface (22) of the holder passage to a position immediately adjacent the opposite inner surface (24) of the holder passage to provide an aperture (30) rearward the flange. The wire bundle, the sleeve and the holder are crimped together at a position forward the shoulder by four dies (64, 66, 68, 70) spaced apart in a circular arrangement.

Abstract: An apparatus for extracting an electrical contact (400) from a housing passage (510), said apparatus including a first member (100) with an internal bore (130) extending rearwardly from a forward end (110) and a second member (200) having a tapered or pointed forward end (211) and movably mounted within the bore of said first member. The electrical contact (400) preferably has a plurality of aligned wires (410) and held within a passage of an electrical connector insert. When the first member (100) is inserted over the contact (400) and the second member (200) is moved forward, the pointed end (211) of the second member urges the wires radially outward and into pressure contact with a portion of the bore (130) of the first member. The axially aligned wires are in pressure contact for removal of the contact simultaneously with the removal of the apparatus. The first member has an axial slot extending rearwardly from the forward surface to accommodate a bent wire.
