This instruction sheet covers assembly procedures for
the shielding hardware kits listed in Figure 1. The kits
are used to construct an RFI/EMI–shielded connector
assembly for customer–applied overmolding which
requires a plastic injection
molding process.
Read these instructions, and all referenced material,
before assembling the kits. Detailed operating
procedures are provided in the instructions packaged
with the crimping die assemblies and tooling.

Reasons for reissue of this instruction sheet are
provided in Section 6, REVISION SUMMARY.

Each kit includes an AMPLIMITE HDE–20, HDP–20,
or HPD–22 connector, an inner shield, and an outer
shield.
The connector (plug or receptacle) features slots on
the rear of the metal shell which are keyed to accept
hinge tabs of the corresponding shield.
The metal shields are designed to hinge on the rear
of the metal shell of the connector. The two parts of
the shield assembly are designed as inner and outer
due to their mating characteristics. The inner shield
always hinges on the shorter side of the keystone
configuration and the outer shield hinges on the
longer side. The inner shield locks into the outer
shield with a pair of latching tabs.
An appropriate ferrule must be ordered separately. It
is crimped by tooling fitted with a die assembly and is
used to secure the shield assembly and cable. The
larger diameter end of the ferrule fits onto the braid
crimp area of the shield assembly, and the smaller
diameter end fits over the cable jacket.

The contacts will accept solid or stranded wire with an
individual wire size range of 28 through 18 AWG.
Prepare the cable as follows:
1. Obtain the connector and cable of the type and
size required for your application. See Figure 2.
2. Slide the appropriate ferrule, smaller diameter
end first, onto the cable. See Figure 3.
3. Strip the jacket to dimension shown in Figure 3.
Then fold braid back over cable jacket.

4. Terminate individual wires onto connector
contacts.

Scotch
Tape 44 (or equivalent), 9.53 mm [.375 in.] wide.
Wrap the tape around the terminated contacts two
complete times. See Figure 4.

2. Insert the hinge tabs of the inner shield into the
corresponding slots of the connector and rotate the
shield 90
_
toward the cable. See Figure 6.
3. Insert the hinge tabs of the outer shield into the
corresponding slots of the connector. See Figure 6.
4. Make sure that the inner shield is in its final
position and close the outer shield until it latches
onto the inner shield with the two latching tabs fully
engaged. See Figure 7.

1. Refer to Figure 1 and determine the crimping
die assembly and tooling to be used for crimping
the ferrule.
2. Crimp the ferrule onto the shield assembly and
cable.
3. Examine the terminated assembly according to
Figure 8 and, if necessary, trim excess cable braid
from the braid crimp area.
