408-8581 2 of 3 rev c figure 2 4.2. crimping the ferrule (see figure 3) 1. insert the crimped center contact into the connector body until the cable dielectric butts against the dielectric inside the connector body or until the center contact is securely positioned within the connector. make sure that the braided shield is over the support sleeve of the connector body and that no strands from the shield enter the connector body. 2. slide the ferrule over the braided shield and onto the connector until the ferrule butts against the shoulder on the connector body. 3. place the ferrule in the ferrule crimping chamber of the anvil die so that the shoulder of the connector body butts against the edge of the die. refer to the instruction sheet packaged with the connector to determine the appropriate crimping chamber for the ferrule. 4. while holding the assembly together, close the tool handles until the dies have closed enough to hold the ferrule in place. make sure that both sides of the ferrule are started evenly into the crimping chamber. do not attempt to crimp an improperly positioned ferrule. 5. carefully close the tool handles until the ratchet releases. figure 3 6. allow the tool handles to open fully, and remove the crimped ferrule from the dies. 5. maintenance and inspection the crimping die assembly is inspected before shipment; however, it is recommended that the dies be inspected immediatel y upon arrival at your facility to ensure that the dies have not been damaged during shipment. the die assembly will perfor m correctly as long as: (1) the product specified is correct for the application, (2) the specified die assembly is used, (3) the die assembly has been measured to ensure that the die crimping the center contact upper and lower die posts must enter slot in contact in order to crimp wire. if not properly aligned, damage to die set will occur. caution ! center contact typical die assembly center contact crimping chamber of anvil die flange against die flange against die plug center contact jack center contact note i caution ! typical die assembly crimping the ferrule ferrule crimping chamber of anvil die shoulder of ferrule against edge of die
408-8581 3 of 3 rev c openings are correct, and (4) the tool has been adjusted correctly. 5.1. maintenance 1. remove dust, moisture, and other contaminants with a clean, soft brush, or a clean, soft, lint-free cloth. do not use any objects that could damage the dies or tool. 2. make sure that the proper retaining screws are properly secured. 3. when the dies are not in use, store them in a clean, dry area. 5.2. inspection 1. remove all lubrication and accumulated film from the dies by immersing the dies in a suitable commercial degreaser. 2. make certain that all retaining screws and die components are properly secured. 3. inspect the crimping surfaces for flattened, chipped, worn, or cracked areas. if damage is evident, the dies must be r eplaced. refer to section 6, replacement. 5.3. measuring the die opening measure the die opening to ensure that it meets the dimensions given in figure 4. 6. replacement order additional die assemblies through your representative, or call 1-800-526-5142, or send a facsimile of your purchase order to 717-986-7605, or write to: customer service (038-035) tyco electronics corporation po box 3608 harrisburg pa 17105-3608 figure 4 7. revision summary ? updated document to corporate requirements ? added new artwork to figure 4 die assembly dimension ab 91911-1 4.395 [.1730] 0.457 [.0180] 91911-2 3.580 [.1409] 0.472 [.0186] 91911-3 2.845 [.1120] 0.510 [.0200] 91911-4 2.845 [.1120] 0.380 [.0150] a 0.051 [.002] b 0.030 [.0011] b 0.030 [.0011]
