  • the strip of terminals 28 is fed along this first support surface during operation of the applicator with a portion of the strip resting on the surface 114, as will be described.
  • the first support surface includes a shallow groove 118 that serves as a clearance channel for the point of the feed finger 120.
  • a first angle member 126 is secured to the plate 90 by means of two screws 128 that extend through the elongated holes 108 and 110 and into threaded holes 130 and 132 formed in the angle member, as best seen in Figures 3 and 4.
  • the first angle member includes a second support surface 134, as best seen in Figure 3, that is spaced away from the first support surface 114. The spacing is selectively controlled by loosening the screws 128, moving the first angle member to a desired position, and then again tightening the screws.
  • a second angle member 136 similar to the first angle member 126, is secured to the plate 90 by means of two screws 138 that extend through the elongated holes 108 and 110 and into threaded holes 140 and 142 formed in the angle member, as best seen in Figures 3 and 4.
  • a back rail 144 has a U-shaped cross section, as shown in Figure 3, and includes an elongated member 146 having a downwardly turned flange 148.

  • the elongated member 146 includes another downwardly turned flange 160 opposite the flange 148.
  • the flange 160 includes a guide surface 162 that is spaced above a plane 164 defined by the first support surface 114 and to the right of the shoulder 116, as viewed in Figure 3.
  • the elongated member 146 includes a turned up flap 166 at one end thereof that serves as a lead-in for the strip of terminals 28 and prevents stubbing as the terminals are fed during operation of the applicator.
  • the position of the guide surface 162 can be adjusted vertically with respect to the plane 164 and laterally with respect to the shoulder 116.
  • the vertical adjustment is accomplished by loosening the screws 150 and sliding the flange 148 up or down to the position desired and then again tightening the screws 150.
  • the lateral adjustment is accomplished by loosening the screws 138 and sliding the second angle member 136 laterally to the position desired and then again tightening the screws 138.
  • the guide surface 162, the shoulder 116, and the first and second support surfaces 114 and 164 cooperate to accurately position and guide the strip of terminals 28 along a terminal feed path 170 to the crimping tooling 20 and 22.

  • the feed finger guide includes a guide slot 192 for guiding the feed finger 120 during feeding in the usual manner.
  • the screw 86 When initially setting up the applicator 10 for feeding a particular terminal 30, the screw 86 is loosened and the lead screw 58 is rotated to position the feed path 170 in relation to the crimping tooling 20 and 22 so that the terminals will be properly aligned.
  • the positions of the second support surface 134 and the guide surface 162 can be varied with respect to the first support surface 114 and the shoulder 116 to accommodate terminals having different shapes and sizes.
  • the terminal 30 is very short and therefore, does not require the second support surface 134. Sufficient vertical support is provided by the first support surface 114.
  • the edge 178 of the strip of terminals which may be the edge of the carrier strip, is closely adjacent the shoulder 116 while another feature 180 is closely adjacent the guide surface 162. This effectively holds the strip of terminals between the shoulder and the guide surface during feeding.
  • the second angle member 136 is positioned on the plate 90 so that only a small amount of clearance exists between the strip of terminals and the shoulder 116 and guide surface 162 thereby preventing any appreciable left or right movement of the terminal strip while permitting free movement of the strip along the feed path 170.
  • the flange 148 is positioned with respect to the second angle member 136 so that the flange 160 does not interfere with the positioning of a first portion 186 of the terminal strip which rests flat on the first support surface 114, while the guide surface 162 is in guiding relationship with some feature of each of the terminals.
  • the positions of the second support surface 134 and the guide surface 162 must be adjusted.

  • first and second angle members 126 and 136 and a back rail member 144 of a specific structure it will be appreciated by those skilled in the art that this is by way of example only, and that other suitable structures my be utilized in the practice of the present invention.
  • the important features of the present invention include the first support surface 114, the positionable second support surface 134, the shoulder 116, and the positionable guide surface 162.
  • the specific structure of the components that contain these important surfaces may vary while staying within the scope of the present invention.
  • the present terminal feed assembly 26 can be adjusted to receive and accurately guide a variety of strips of terminals of different types and sizes thereby eliminating the need to acquire and maintain many different feed track components for the various different terminals.
