ABSTRACT:
A hand held compressed air powered crimping tool is used both to secure ring tongue terminals to stripped electrical wire ends, and to secure butt splices that join together two electrical wire ends. The dies used, their locations, their retention, and their movements are similar to existing "T" head crimping tools, which are finger and hand manipulated and powered. When using this compressed air powered tool, pre-positioning is still undertaken by fingers and hands, of wires, ring tongue terminals or the butt sleeves, and insulation covers, to be crimped. Continued finger and hand movements, move together respective "T" head portions to preliminary keep together all the members to be crimped, in their respective positions. At the conclusion of the preliminary positioning, no spaces are left around dies for any unwanted entry of finger portions of the operator. At the last moment of the preliminary positioning, a blocking member of a safety linkage is cleared away from respective receiving volumes, permitting the subsequent entry of respective depending safety portions of a finger actuated hinged lever trigger. The trigger, when intentionally moved, depresses an upstanding air valve stem to open the air valve for the flow of compressed air to the pneumatic actuator that completes the movements of the overall crimping linkage. Preferably, a monitoring linkage is moved during the preliminary positioning, to insure the members to be crimped are securely held, until the compressed air power is subsequently utilized. The monitoring linkage must complete its travel during the powered fall crimping action directional sequence period, before it reverses its travel direction to clear the way for a release opposite directional movement of the crimping linkage undertaken, when compressed air power is off, and a return force is provided by a compression spring.
