Patent number: 5060360Abstract: The present invention is an apparatus for and method of aligning the terminals of a group of connectors in side by side abutting relationship with tooling for terminating wires to the terminals thereof. The group of connectors is placed in a track with the first connector against a stop. A plurality of vertically reciprocal guide blades are arranged adjacent the track and are moved upwardly, one at a time, the first engaging the first connector and positioning it relative to the termination tooling followed by subsequent blades engaging the other connectors. These subsequent engagements occur one at a time in sequential order with increasing distance from the stop. When all connectors are positioned by engaging guide blades, wires are terminated to the connector terminals and the guide blades moved out of engagement so that the completed connector assembly can be removed and the process repeated.Type: GrantFiled: January 26, 1990Date of Patent: October 29, 1991Assignee: AMP IncorporatedInventors: Bryan J.

Patent number: 5007845Abstract: The present invention sets forth a low height socket for an integrated circuit chip carrier of the "Tape Pak" type. The unique contact is arranged in the shape of a tuning fork. The chip carrier, having flexible leads projecting outwardly from its sides, is placed in the lower body of the socket with the leads resting on top of their respective tuning fork contacts. The cover, having locking members projecting downwardly and in alignment with the tuning fork contacts, is forced into engagement with the lower body so that the locking members deflect the leads downwardly, bending them about the contacting portion of the tuning fork shaped contacts. The two arms of each tuning fork then has the locking member and a respective lead wedged therebetween.Type: GrantFiled: November 3, 1989Date of Patent: April 16, 1991Assignee: AMP IncorporatedInventor: Dimitry G.

Patent number: 4967654Abstract: A method and apparatus for setting a plurality of print wheels, in an automated cable making machine for imprinting a desired set of characters onto a connector housing. The method includes a unique way of homing each of the print wheels to a known position prior to setting the print wheels to their desired print positions. This is a done by rotating each print wheel until a rod, which is constrained to move only along its longitudinal axis, can be inserted into an opening in the print wheel. This prevents further rotation of the print wheel thereby indicating that the wheel is in its home position.Type: GrantFiled: July 10, 1989Date of Patent: November 6, 1990Assignee: AMP IncorporatedInventors: Michael D. Strong, Charles E. Zimmermann

Patent number: 4936496Abstract: Strip feed mechanism comprises an intermittently rotated sprocket wheel which engages the strip material. A guide plate extends tangentially past the sprocket wheel and serves to hold the strip material against the wheel and in engagement with the sprocket teeth. At the end of a feeding interval, the guide plate is moved away from the sprocket wheel by a bell crank mechanism. The bell crank mechanism comprises a bell crank having a movable axis which, in combination with other features of the mechanism, permits the guide plate to be moved away abruptly from the sprocket so that the feeding interval is brought to an abrupt halt without "chattering" or other slight uncontrolled movement of the strip.Type: GrantFiled: June 3, 1987Date of Patent: June 26, 1990Assignee: AMP IncorporatedInventor: Johannes C.
