Definitions

  • the present invention relates to the field of electrical connectors and more particularly to high density connectors.
  • connectors known in which a plurality of terminals are disposed in rows of respective passageways of an insulative housing, with contact sections exposed along a mating face of the connector, and the terminals are terminated to respective conductors at termination sections along a rear face of the housing.
  • One such connector is disclosed in U.S. Patent No. 3,760,335 wherein the terminals are inserted into the respective passageways prior to being terminated to respective conductors, and are arranged in two rows. Once loaded into the passageways, the termination sections of the two rows of terminals are exposed along opposite sides of the housing for termination.
  • the termination sections are of the type known as insulation displacement (IDC) , wherein a pair of parallel axially spaced plate sections traverse the conductor's path and defines a pair of slots between pairs of opposed beams; as the insulated wire is urged into the slots from beside the terminal, the beam edges cut through the insulation layer and engage and compress against the conductor to establish a pair of electrical connections between the terminal and the conductor.
  • Insulative covers are utilized to simultaneously urge all the conductors of respective rows into their slots for termination while maintaining the appropriate spacing between the conductors, and thereafter become latched to the connector housing to protectively cover the terminations and maintain the conductors in the slots. It is desired to provide an electrical connector with a plurality of rows of closely spaced terminals enabling termination to respective conductors through insulation displacement along a common side of the connector housing.
  • the present invention provides a connector wherein the termination sections of the terminals of a plurality of rows are exposed along a common side of the connector, for termination to respective conductors, where the terminals are molded into the housing.
  • the termination sections are of the insulation displacement (IDC) type, and all conductors may thus be terminated by being urged into the IDC termination sections from a common side of the housing.
  • IDC insulation displacement
  • the IDC termination sections of the two rows are staggered axially, so that the row farther from the side of the connector from which the conductors will be urged into the slots for termination, is positioned rearwardly from the IDC termination sections in the nearer row to provide a clearance for conductor termination. Additional rows could be provided with similar staggering.
  • the IDC termination sections of adjacent terminals may be spaced axially to provide clearance from the next adjacent ones enabling close lateral spacing between terminals for greater density.
  • the terminals may be molded in place within the connector housing in a manner exposing the IDC termination sections for eventual conductor termination, and also exposing the contact sections along the mating face, a manufacturing technique generally known.
  • core pins are utilized to engage the body sections of the terminals during molding for positional stability. So that the core pins extend from the same side of the mold, given that the terminal density is high, and the body sections of the terminals must be aligned between rows, the terminals of a certain row are formed to define lateral offsets enabling the core pins to pass by the terminals of that row to reach the terminals of another row positioned in vertical alignment therewith. Termination covers preferably are used to provide protective insulative covering of the terminations and to thereafter maintain the conductors in the slots.
  • FIGURE 1 is an isometric of a connector assembly of the present invention from rearwardly thereof with representative wires extending therefrom;
  • FIGURE 2 is a side view of the connector of FIG. 1 prior to wire termination, with termination covers poised to be applied to the connector to terminate the wires to respective terminals, and with portions of the shell broken away to reveal detail of the housing;
  • FIGURE 3 is a longitudinal section view of the connector housing and terminals after the insert molding process, with upper and lower mold halves opening and core pins withdrawing from the molded housing;
  • FIGURES 4 through 7 are plan and elevation views of the terminals of the upper and lower rows, respectively;
  • FIGURE 8 is an isometric view illustrating the connector housing and terminals of the assembly of FIG. 1 prior to wire termination;
  • FIGURE 9 is a plan view of the rear face of the connector of FIG. 8, with a termination cover poised for attachment to the connector;

Abstract

Un connecteur électrique (10) comprend un logement (12) moulé autour de parties de corps d'une pluralité de bornes (40, 42, 44, 46) disposées en premières et secondes rangées. Les bornes présentent des sections de connexion à dénudation (32, 34, 36, 38) destinées aux fils respectifs (22, 24) à introduire dans ces dernières par les couvercles de connexion (26, 28). Toutes les sections de connexion à auto-dénudation s'étendent dans une direction commune à partir d'un côté du logement (12), et celles (32, 34) de la première rangée sont étagées vers l'arrière à partir de celles (36, 38) de la seconde rangée afin de faciliter l'insertion des fils. Le procédé de moulage consiste à ménager des pointes centrales (92, 94) destinées à porter les bornes à partir d'une moitié (74) des moitiés de moule, et des bornes inférieures (40, 42) présentent des décalages latéraux (134) permettant le passage des pointes centrales (94) afin d'atteindre les bornes supérieures (44, 46) alignées verticalement avec ces dernières
