Definitions

  • This invention relates to electrical connector plugs and more particularly to spring latch hand plugs that hold against pressure on the front portion but are readily withdrawn by a pull on the rear portion.
  • the spring parts are made of material different from that of the shell portion of the plug, thereby requiring that the spring par-ts be manufactured separately from the shell portion.
  • Another problem is the insertion of the spring arts into the shell portion during manufacture of the plug.
  • a further problem is the probability that the spring parts may extend too far above the shell portion until they form a permanent engagement which is undesirable.
  • An additional object of the present invention is to provide an effective arrangement to prevent the removal of the plug from .a control panel upon force being applied to the front or tip portion thereof.
  • a still further object of the present invention is the provision of a detent system wherein the spring detent member thereof is integral with the plug shell and of a character susceptible to precise control of shape.
  • FIGURE 1 is a perspective view of an embodiment of a snap latch plug incorporating features of the present invention
  • FIGURE 2 is a fragmentary longitudinal sectional view of the plug of FIGURE 1 illustrating the action of the detent system during insertion of the plug in a plugboard aperture;
  • FIGURES 3 and 4 are views similar to that of FIG- URE 2 in a further stage of insertion and final position respectively of the plug in the plugboard aperture;
