ABSTRACT:
A compression tool head assembly for compressing a metal connector about a conductor to be connected. The assembly is adaptable to make both parallel tap connections and sleeve connections. The assembly includes a head section having two, opposing arms moveably connected thereto, each of said arms having a nib thereon; a rigid column disposed between said opposing arms and having a reversible die mounted therein, said die having a nib at one end and a "C" shaped section at its other end; a hydraulic pump section is connected to the head section and operates to move the head section towards the rigid column; the arms have cammed surfaces which interact with rollers fixed to the rigid column to cause the arms to move towards each other as the head is moved towards the rigid column; as the arms move towards each other the nibs will compress an article disposed therebetween; the arms having a connecting pin arrangement at their outer ends such that they may be pivoted and joined together; the nibs on the arms are formed such that when the arms are joined together an upper "C" section is formed; by reversing the die in the rigid column the "C" section in the die forms a lower "C" section against which the upper "C" section will move to compress a connector.
