2D/CTA CENTI-LOC™ Connectors Assembly Instructions
The Double Density D/CTA CENTI-LOC Connectors
are highly reliable and simple connectors to use.
There are a few helpful suggestions that will assure
complete satisfaction when followed:
1. The following insturctions should be followed.
2. The proper crimp tool and locator (if required)
must be used. These tools have been designed
for use with this product. Substitutions of crimp-
ing equipment may result in connector failure at
the assembly operation.
3. After crimping a contact to a lead it is of vital
importance that the proper tool be used to
assure seating the contact in the insulator in the
proper posistion. Any substitution of insertion
tools may result in over or under insertion of the
contact which will damage the retention system
of the insulator.
4. The female (socket) side of the connector has
been designed with a controlled float to allow
for ease of mating. To avoid reducing this float
or causing a splaying of the contacts, any
unnecessary strain by clamping too close to the
rear of the connector should be avoided.
Use of recommended tooling together with proper
assembly techniques will pay dividends in reliability
and reduced costs.
2D Assembly Instructions
WIRE STRIPPING
CONTACT CRIMPING
.100
(2.54)
Cut the wires to length required and strip .100" of insulation
from the end to be crimped. Check for cut or broken wires
and frayed insulation.
CONTACT INSERTION
Using the proper crimp tool and locator, insert the contact into
the locator. Insert the stripped end of the wire into the contact
crimp pot, and crimp the contact to the wire. Squeeze the
handles firmly to insure a proper crimp (tool will not release if
crimping is incomplete). NOTE: Contact stop must be changed
in tool locator when crimping pin and socket contacts.
1. Place the proper insertion tip in the insertion/-extraction
handle and put the tip over the wire as shown. The tool tip
will butt up against the crimp pot. Connector must be firmly
supported during both insertion and extraction operations.
CONTACT EXTRACTION
2. Using a firm, steady pressure, pust the contact into the
cavity until the resilient internal shoulder in the insulator
snaps into the locking groove in the contact. The shoulder of
the tool tip bottoms against the rear of the insulator,
preventing over-insertion. Repeat for balance of contacts.
1. For contact extraction, remove the insertion tool tip and
replace it with the proper extraction tool tip. (The socket tip
will fit into the socket, and the pin tip will slide over the pin
bundle). Insert the tool tip into the contact cavity: (the pin tip
will butt up against the shoulder of the pin contact, and the
socket tip will bottom in the socket contact.)
2. Apply a firm, steady pressure until the contact is released
from the internal shoulder in the insulator. The shoulder of
the tool tip bottom against the insulator face to prevent
damage to the internal shoulder. Remove the tool tip and pull
the contact from the rear of the connector. Repeat for the
balance of contacts to be removed.
