ABSTRACT:
A compression tool head assembly for compressing a metal connector about a conductor. The assembly includes a head section having two, opposing arms moveably connected thereto, each of the arms having a compression point thereon; a rigid column disposed between the opposing arms and having a die mounted therein, the die having a compression point at one end and a mechanism for centering the cylindrical connector over the compression point at approximately a central location between the arms prior to compressing the connector; 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 compression points on the arms will compress an article disposed therebetween.
