Definitions

  • the present invention pertains to connector assemblies comprising intermating dielectric housing and conductive terminal members.
  • the present invention pertains to connector assemblies having two-piece housings, and crimp-type terminals.
  • electrical connectors must have often been made to exhibit a high mating force, for a variety of reasons. For example, in contaminated environments, a high mating force ensures the removal of any oxide coating or the like contamination, which is necessary for a reliable electrical contact, and a gas-type seal at the point of electrical connection. Also, if a significant number of circuits are provided in a given electrical connector, high insertion and withdrawal forces will necessarily tend mating and unmating of two interengaging connector members. Accordingly, an arrangement must be provided to ensure that a terminal is retained within its dielectric housing.
  • This terminal retention feature is often required during mating of an electrical connector pair to prevent terminal push-out, as well as during unmating of an electrical connector pair when a terminal may be pulled out by either the force of unmating, or an operator applying tension to the wires connected to one mating connector part.
  • some connector arrangement has terminals with mating portions located off center from the axis of the remaining terminal body.
  • Other terminals have asymmetric cross sectional configuration, such as blade or flag-type terminals.
  • the relative angular orientation of the terminal with respect to its dielectric housing is crucial for successful connector operation. A ready visual indication of angular terminal orientation is desired.
  • the present invention provides an electrical connector assembly as defined in claim 1.
  • the carrier includes first and second opposed outside surfaces spaced-apart to form a predetermined width of the carrier, the open carrier receiving end having a width substantially equal to the carrier width so as to permit passage of the carrier therethrough, the carrier channel having a predetermined depth extending from the open side at the first surface, a terminal-crimp-portion engaging member having a predetermined height extending into the channel which, when combined with the terminal crimp portion cross sectional height, presents a minimum combined height equal to the depth, to allow insertion of the carrier within the housing open end, whereby a ready visual indication of excessive crimp portion cross sectional height is provided during assembly of the connector, with the terminal interfering with the housing to prevent insertion of the carrier within the housing.
  • the terminal crimp portion cross section has a minimum height only at a predetermined angular orientation to the terminal-crimp-portion-engaging member which, when combined with the terminal engaging member, presents the minimum combined height equal to the depth, whereby other angular orientations of the terminal present an increased combined height which causes the terminal to interfere with the housing during assembly of the connector.
  • Assembly 10 includes a terminated wire subassembly 12 comprising a terminal 14 engaging an insulation clad wire 16.
  • Terminal 14 has a crimp-type engaging portion and wire 16 has a leading bared end, suitable for a conventional crimp connection.
  • the terminated wire subassembly 12 is mounted in a two-piece housing assembly comprising a carrier member 18 and a cover-like housing 20.
  • the connector assembly shown in FIG. 1 comprises a single planar array of terminated wires, whereas the embodiment of FIG. 2 has a second planar array of wires arranged back to back with the arrangement of FIG. 1.
  • the carrier member 18' of FIG. 2 is conveniently integrally molded to contain both planar arrays but in other features is identical to the arrangement of FIG. 1.
  • the features of the carrier and housing members of FIG. 2 bear the same numerals as in FIG. 1, but have a prime designation when geometrically different. That is e.g. the numeral 20' is applied to the housing member of FIG. 2 since it differs only in relative size from housing 20 of FIG. 1.
  • the terminal 14 of subassembly 12 comprises a forward mating part 30, a rear strain relief portion 32, and an intermediate crimp-type wire engaging portion 34.
  • mating part 30 has a cross-sectional height roughly equal to the sum of the vertical dimensions HT and HP, whereas the wire engaging portion 34 has a reduced cross-sectional height equal to HT alone.
  • the trailing strain relief portion 32 has a cross sectional height substantially greater than that of wire engaging portion 34.
  • wire engaging portion 34 and strain relief portion 32 are simultaneously formed in a single die to comprise a crimp part of repeatable size and shape.
  • wire engaging portion 34 is conveniently applied to a bared leading portion 16' of wire 16, and is inwardly deformed and compressed about that bared portion. As indicated in FIG. 4, wire engaging portion 34 when terminated to wire 16 has an elongated cross section, a feature which is relied upon to provide a ready visual indication of the terminal's angular orientation. As is appreciated by those skilled in the art, the amount of inward deformation or compression of wire engaging portion 34 about wire 16 is crucial to the proper electrical connection between the terminal and wire.
  • the wire-engaging portion is formed by placing terminal 14 on an anvil-like die, inserting the bared leading end 16' of wire 16, and lowering an opposed crimping die so as to deform wire-engaging portion 34, compressing it so as to establish mechanical and electrical engagement with the conductor portion of wire 16.
  • One problem that may affect connector performance, is the inadequate compression of the wire-engaging crimp portion by the mating die members. Inadequate compression of the wire-engaging crimp portion would result in a "crimp height" HT greater than the desired amount.
  • the connector assembly being described provides a ready visual indication of such improperly enlarged crimp height.
  • housing 20 has a mating end 40, and opposed open carrier receiving end 42, and a carrier receiving cavity 44 extending between those ends.
  • carrier receiving cavity 44 has a constant cross-sectional dimension throughout the length of housing 20, although this is not essential.
  • Housing 20 is conveniently provided with a pair of opposed locking windows 46 to maintain the engagement between carrier 18 and housing 20.
  • Carrier 18 includes a plurality of terminal receiving channels 50 having a depth d (see FIG. 3) extending between opposed outside surfaces 52, 54.
  • Channels 50 have an open side 58 which, open to surface 52, allow transverse loading of terminated subassemblies 12.
  • the depth of channel 50 is less than the overall width of the carrier WC only by an amount equal to the thickness of the bottom channel wall 60 which opposes the open side 58.
  • terminated subassemblies 12 are loaded in a transverse direction into terminal receiving channels 50, and are temporarily held therein during connector assembly by resilient finger portions 64.
  • Carrier 18 is thereafter telescopically inserted in the open end 42 of housing 20.
  • Outwardly projecting locking portions 68, formed adjacent the trailing end of carrier 18 are received in locking windows 46, to maintain the engagement between dielectric members 18, 20.
  • carrier 18 designated WC in FIG, 1
  • the width of carrier 18, designated WC in FIG, 1 is closely held to the internal width WH of the open end 42 of housing 20 to provide a close tolerance interfitting relationship.
  • any protrusion of terminal 14 beyond carrier surface 52 will interfere with the side wall 70 of housing 20 preventing a complete insertion of carrier 18 within the housing.
  • a terminal engaging member 74 projecting a predetermined cross-sectional height HP into channel 50.
  • the height HP of engaging member 74 is chosen such that when added to the thickness of bottom wall 60, and the height HT of wire-engaging portion 34, the combined total of these heights equals the width WC of carrier 18. Therefore, if the crimp height HT of wire-engaging portion 34 exceeds its specified value, the overall width of the installed terminal and carrier will exceed WC, preventing insertion of carrier 18 in housing 20. Thus, a ready visual indication of a proper crimp height is provided.
  • terminal engaging member 74 the above-described features of terminal engaging member 74 are advantageously employed to provide a ready visual indication of the angular orientation of terminal 14 relative to carrier 18.
  • the cross section of wire-engaging portion 34 is elongated in an amount greater than HT, the maximum crimp height allowed by the complete carrier insertion in housing 20.
  • any angular displacement of wire-engaging portion 34 (and hence of mating portion 30) will result in a protrusion above carrier surface 52. Therefore, the wire-engaging portion 34 is provided with a unique angular orientation at which the crimp height HT is a minimum.
  • terminal engaging member 74 closely approximates the gap of reduced terminal width appearing between terminal portions 30, 32. Any axial displacement of terminated subassembly 12 will cause an interference with engaging member 74.
  • the arrangement described offers greatly enhanced retention capability. Terminal retention is ensured in the direction of terminal push-out, as well as terminal pull-out, the terminal being held captive in its engagement with member 74 by the closely fitting housing member 20.
