Assembling electrical connecting device to cordage

摘要

In order to assemble modular plugs, comprised of two mating dielectric parts and plural blade-like terminals, to each end of a jacketed telephone cord, an operator positions each unfinished end of a length of cordage in a transfer device and then initiates the operation of an assembly apparatus. The transfer device transfers each end of the cord to a workholder while mating dielectric parts are fed separately to each of two assembly positions and in vertical alignment with a horn and anvil of ultrasonic bonding facilities. One of the parts in each assembly position is supported on the anvil while the other part is held in the horn. Each of the workholders is turned rotatably to move the cordage end held therein into the assembly position and into vertical alignment with the spaced apart portions of the modular plug. The jacket is removed from the end portions of the cord to expose the individually insulated conductors whereafter the anvil is moved upwardly to position the conductors in conductor-receiving troughs in the one part. Simultaneously, the horn is lowered to engage the other part with the one part and bond the parts together. The blake-like terminals are moved upwardly through the anvil and into terminal-receiving grooves in the one part and into electrical engagement with the conductors. Excess lengths of the conductors are severed and together with the stripped jacket are removed. The workholders are returned to initial positions and cammed open to release the plugged cord ends and permit the finished cord to drop into a receptacle.
