1522863 Electrical connectors AMP Inc 20 Jan 1976 [5 Feb 1975] 02101/76 Heading H2E An electrical contact 19 is stamped and formed from a single piece of sheet metal and comprises two plates 21 each having a respective one of two aligned slots 23, each slot having a blind end in the respective plate and opening at one end of the plate, the slots extending between transverse portions 22 that connect the plates together at one end thereof. The other end of one plate is adapted for connection to a wire, and a tang 26, 27 is provided on an edge of a plate 21. As described, contacts 19 are received as an interference fit in respective cavities, e.g. in box like structures 16, formed in an electrically insulating housing moulded of plastics material. The cavities each have opposed walls having slots 17 that are aligned with the slots 23 of the contact 19. A wire end 28 of a coil 13 is initially passed through the slots 17, and over a projection 18 that extends from the cavity floor. Insertion of a contact 19 into the cavity allows the slots 23 of the contact 19 to cut through the wire insulation. A further wire 29 may then be attached to said other end of one of the contact plates 21. As shown, this connection may be effected by forcing the wire 29 between a V-shaped depression 25 and the adjacent plate 21. Alternatively, the wire 29 may be soldered in an aperture in a single or double thickness tab (Figs. 4 and 6, not shown) wrapped around a double thickness post (Fig. 5, not shown) or crimped in a ferrule portion of a plate 21 (Fig. 7, not shown). Further, in addition to the coil wire 28, one wire 29 may be attached as shown whilst a second may be soldered in an aperture in a plate extension (Fig. 6). The transverse portions joining the plates may be bent upwardly to aid in the positioning of the wire 28 passing through the slots 17, 23 (Fig. 8, not shown).
