This 10- position, modutar connector could then be mated to a 10-position, single-row AMPMODU MTE_ shrouded header with latch. Similarly, two 10-position ribbed housings could be stacked back~to-back inside a double-row coupling shroud to form a 20-position, doublerow connector. This 20-pasition, double-row connector could then be mated to any shrouded, double-row AMPMODU header with a .318-in. mating post length and a .150-in. end dimension. The .150-in. end dimension is measured from the centerline of the fast post to the inside of the end Shroud wail, Other sizes of contact housings may be combined in this manner to form the desirad number of positions. Figure 3 shows typical coupling shrouds, and lists the base part numbers of the shrouds. For information on specific sizes of coupling shrouds, refer to AMP Catalog 85-773. Two housing types are available for pin contacts. One is a fully-shrouded housing and the other is a ribbed housing. After termination, the ribbed housing (with the pin contacts protrucing out of its front) is inserted into the panel-mount shroud. One or more ribbed housings may be used, as is done with the coupling shrouds. A typical panel-mount shroud is shown in Figure 3. The shroud can then be snapped into a panel ta forma bulkhead connector. The mating half is again the latching-style receptacle or the single-row coupling shroud. Both pin and receptacle contacts feature insulation displacement termination for the conductors and are preloaded in the .100-in. centerline, single-row housings. During manufacturing, the contacts are partially inserted, leaving their termination areas exposed at the back of the housing. Final contact insertion into the housings is done by the termination tooling (except when using a hand crimping tool or bench mount power assernbly) .

The post stop prevents the mating post from disturbing the wire bundle at the end of the IDC crimp. The forward contact stop prevents the contact from being overinserted prior to termination. Pin contacts feature the wraparound insulation barrel and forward contact stop as well. Keying plugs and a keying too! are available for the connecter assemblies. Refer to Figure 3 for part numbers for these items. For detailed information on housings and contacts, refer to AMP Catalog 85-773. 3. TERMINATION TOOLING During termination, the unstripped wire enters the two wire slots of the insulation displacement beams, and the insulation barrel forms around the insulation of the wire. Refer to Figure 4 (receptacle contact shown}. The available tooling for terminating the wires is listed in Figure 5. Production requirements will determine the tooling necessary for your application. For assistance PAGE 4 OF 6 in selecting the tooling that will best suit your needs, contact your local AMP representative. 4. ASSEMBLY PROCEDURE Determine thea wire size to be terminated and the housing type desired by referring to the table in Figure 1. Obtain the required tooling for contact termination and proceed as follows: NOTE 1. Ensure that the contacts are properly seated in the housing, with the contact locking lances visible in the preload windows, that the front locator stops are against the back of the housing, and that the contact carrier strips are properly interlocked. Refer to Figure 6. Read the instructional material pack- aged with the termination tooling BEFORE attempting toa terminate any cantacts, 2. Position the housing in the tooling according to the instructions provided with the tooling. 3. Locate the wires in the toaling in accordance with the tooling instructions. 4. Make all of the required terminations.AMPMODU MTE CONNECTORS IS 6919 FRONT LOCATOR STOP AGAINST CARRIER HOUSING STRIPS INTERLOCKED EXTRACTION TOOL CONTACT LANCE TOOL TIP | TOOL LOCKING LANCE LOCKING LANCES WINDOW IN PRELOAD WINDOWS HOUSING AMPMODU MTE SACKING HOUSING (Typ) LANCE PRELOAD CAVITY WINDOW Fig. 6 Fig. 7 5. Remove the terminated housing from the 2. Insert the too! tip into the locking lance cavity tooling. if using AMP Terminating Head 58336-1, the contact carrier strip must be bent downward and broken off after the contacts are terminated. The contacts must then be inserted the remaining distance into the housing until the locking fances en- gage tha locking lance window. 5. EXTRACTING CONTACTS (Figure 7) The contacts can be removed from the contact housings by using AMP Extraction/Reset Tool 843477-1. Refer to AMP Instruction Sheet IS 9453, which is packaged with the tool, for detailed extraction procedure. The tool is designed to depress the locking lance of the contact without deforming or overstressing the contact. Briefly, the procedure is as follows: 1. Align the tool tip with the back of the locking lance cavity. until the tool stop bottams on the housing. 3. Keeping the tool in this position, carefully move the contact ta the preload window of the housing. 4. Repeat Steps 1 and 2 at the preload window of the housing to remove the contact completely. 6. CONTACT REPLACEMENT In the event that a contact becomes damaged, it may be replaced by performing the following procedure: 1. xtract the damaged contact by following the procedure described in Paragraph 5, EXTRACTING CONTACTS. 2. Obtain a preloaded contact housing with the contact type (pin or receptacle) anc wire size (22 through 26 ar 26 though 30 AWG) desired. 3. Carefully terminate the wire onto the first position of the contact housing oy using AMP Manual Pistol Grip Tool 58074-1, equipped with AMP Terminating Head 58336-1. PAGE 5 OF 6IS 6919 4. Cut the carrier strip to free the first (termi- nated) contact from the other contacts on the strip. The remaining contacts may be used for replacements in the future if desired. 5. Break off the replacement contacts carrier strip, and then extract the terminated replacement contact by following the procedure described in Paragraph 5, EXTRACTING CON- TACTS. 6. Reset the locking lance height as described in AMP Instruction Sheet IS 9453. 7. Carefully insert the replacement contact fully into tha contact housing cavity, ensuring that the locking lance is properly oriented. 8. Pull back lightly on the wire to ensure that the contact locking lance is engaged in the locking Jance cavity. 9. AMP Tandem Spring contacts may also be used for contact replacement, in accordance with AMP Application Specification 114-25021. PAGE 6 OF 6 AMPMODU MTE CONNECTORS 7. KEYING AMPMODU MTE receptacle and header assemblies may be keyed by using the following technique: A. Receptacle Assembly 1. Remove a contact from the housing position to bea keyed. Refer to Paragraph 5, EXTRACTING CONTACTS, for the procedure. 2. Insert AMP Keying Plug 87077-2 into the selected contact cavity untit the plugs locking lance engages in the locking lance window of the housing. B. Header Assembly Remove the mating pin contact from the header assembly position being keyed by using AMP Extraction tool 91417-1.
