<p>A tool for facilitating the insertion of an electrical contact into a contact receiving bore of a resilient electrical connector together with a unitary control mechanism for such a tool. The tool has bore enlarging means including a sleeve and a rod coaxially aligned within the sleeve for insertion into the bore of the connector for enlargement thereof. The tool also includes a unitary control mechanism operatively associated therewith which enables relative movement between the sleeve and the rod. The unitary control mechanism includes spring release means which in a first position resists rearward movement of the sleeve and the rod, in a second position permits rearward movement of the rod but resists rearward movement of the sleeve, and again in the first position permits rearward movement of the sleeve for relative sequential movement between the sleeve and the rod. The tool can also include an opening therein having first and second pistons controlled by the unitary control mechanism with the sleeve being secured to the first piston and the rod being secured to the second piston. With such a tool, the unitary control mechanism enables the rod to be retracted within the sleeve for insertion of the contact into the sleeve and thereafter enables the sleeve to be withdrawn from the bore leaving the contact within the connector.</p> |
