2 / 7 page 408- 9359 Rev C 2 of 7 2. DESCRIPTION The terminating head is designed for use in Manual Handle Assembly 58074--1 (408--6790), Pneumatic Handle Assembly 58075--1 (408--6789), Pneumatic Power Bench Assembly 58338--1 (408--9393), and the Electric Bench Machine 931800--1 (409--5746). Note that the pneumatic handle assembly is designed to operate at air pressure between 276--483 kPa [40--70 psi]. The head, when installed in either handle assembly, terminates wires in the single--row AMPMODU MTE contact housing assemblies listed in Figure 1. Refer to Instruction Sheet 408--6919 for a complete description of the AMPMODU MTE Connectors. Note that even though the head terminates both strip--form and individual housing assemblies, it does not terminate individual housing assemblies of less than six positions. Wires are terminated using the Insulation Displacement Technique, which inserts unstripped wire into a slotted contact beam to form a reliable electrical connection between the wire and the contact. After the head is inserted into the tool handle assembly, the head serves as a guide for the housing assemblies during termination. Features of the head and their functions are as follows: Wire Inserter -- forces wire into two slotted beams of the contact and provides support for the contact beams when insertion force is applied to the wire. Adjuster (Insertion Rod) -- is a piston for, and regulates travel of, the wire inserter. Feed Pawl -- advances contact carrier strip to the terminating position. Feed Arm -- driven by the retraction of the inserter, the feed arm drives the feed pawl. Contact Drag -- keeps the contact carrier strip in the strip guide and prevents the connector from moving out of position after the feed pawl advances it. Guide Strip -- aligns and supports the contact carrier strip. Feed Adjustment Screw -- regulates position of contact relative to the wire inserter. 3. ADJUSTMENTS 3.1. Feed Adjustment The insulation barrel supports on the contact must be centered on the wire inserter when the contact is in the terminating position. The feed adjustment screw regulates the travel of the feed pawl which advances the contact to the terminating position. Make this adjustment as follows: 1. Obtain a housing assembly. Refer to the chart in Figure 1. 2. Squeeze the tool trigger (pneumatic handle assembly or cam handle (manual handle) and push the housing assembly against the wire inserter. 3. Release the trigger or cam handle; the housing assembly will be indexed to the first contact position. 4. Squeeze the trigger or cam handle until the feed pawl clicks; then release the trigger or handle. The housing assembly should have advanced to the next contact position. 5. Squeeze cam handle until the wire inserter is partially extended but does not touch the insulation barrel supports. If using a pneumatic handle assembly, reduce air pressure to 0 kPa [0 psi], squeeze the trigger, and increase air pressure until the wire inserter is partially extended. Refer to Figure 2. Figure 2 Feed Pawl Contact Wire Inserter Feed Adjustment Screw 6. To advance the contact, turn the feed adjustment screw COUNTERCLOCKWISE. To back up the contact, turn feed adjustment screw CLOCKWISE while pulling back on the carrier strip. 7. Repeat Steps 4 through 6 as necessary. |
