An applicator is provided for inserting a terminal in a hole in a circuit board comprising terminal insertion tooling, having an elongated insertion blade and a pair of preloaded spring fingers, and an anvil including a retractable locating and gauging pin surrounded by an actuator collar. A hole in a circuit board is positioned on the locator pin and the circuit board depressed against the actuator collar. The locating pin is retracted. A ram extends the terminal insertion tooling. The preloaded spring fingers hold the terminal in alignment with a hole in the circuit board and the tool inserts the terminal into the hole. The insertion tool is then retracted and the retractable locating pin is extended to permit positioning of another circuit board hole on the locating pin and subsequent insertion of another terminal.

Field of the Invention
The invention relates to applicators for inserting terminals into holes in a circuit board.
Description of the Prior Art
FIG. 1 is a front view of a preferred embodiment of the terminal applicator of the present invention.
FIG. 2 is a side view of the terminal applicator of FIG. 1.
FIG. 3 is a front view in detail of the terminal insertion means and feed means of the applicator of FIG. 1.
A preferred embodiment of the invention is described below with reference to the attached figures wherein the same numerals are used throughout for illustrating the same elements.
The terminal applicator of the present invention comprises a C-frame 10 including a base 12 and an upper frame arm 14. An anvil assembly 16 including a locating pin and actuator assembly 18 is mounted on the base 12 of the C-frame 10. A head assembly 20 including terminal insertion tooling 22 and feed means 24 is mounted on the frame arm 14 of the frame 10 above anvil 16. An extendable arm assembly 26 is mounted on arm 14 of the frame 10 and connected to the head assembly 20. A feed reel mounting assembly 28 is mounted on arm 14 of the frame 10.
The general operation of the terminal applicator may be readily understood with reference to FIGS. 1, 2, 10 and 11 in the attached drawings. A hole H in a circuit board B is positioned on the locating pin and actuator assembly 18 of the anvil assembly 16. Depression of the actuator assembly 18 actuates the control means which rapidly retracts the locating pin into the anvil assembly 16 and extends the ram assembly 26 connected to head assembly 20. The ram assembly 26 drives the insertion tooling downward. The insertion tooling 22 grasp terminal T, severs the terminal from the carrier strip S, and pilots and inserts the terminal T in hole H in the circuit board B. The ram assembly 26 and the insertion tooling 20 are retracted. The locating pin assembly 18 is extended. The board B is repositioned to place another hole H over the pin and actuator assembly 18. The board is depressed against the actuator and the cycle described above is repeated to insert another terminal T into another hole H in the circuit board B.
