General
3M™Manual and Pneumatic Assembly Presses and
accessory assembly equipment are recommended for the
termination of D Sub Connectors. 3M assembly equipment
is offered to reduce set-up time, to provide easier and
faster assembly, and to reduce assembly error.
The 3443-112 Locator Plate and 3442-44 Platen were
designed to assemble the 8250 D Sub Connector. The
3443-112 Locator Plate is used with the 3442-1A Platen to
assemble the 8350 D Sub Connector.
*Included with the 3343-112 Locator Plate is a 3442-44 Platen.

Procedures for
Connector/Cable Assembly
1. Grasp a D Sub cover strip between thumb and
forefinger of both hands, with the liner facing you.
Rotate the outermost cover down against the adjacent
cover on the strip, breaking it from the liner. Pull
laterally away from the strip. Adhesive should be
present on cover.
(See Figure 5)
2. Firmly press the ribbed side of the cable into alignment
grooves on cover. The adhesive will help the cable stay
in place. Visually inspect to ensure that:
a. Cable is properly aligned to cover grooves.
b. Cable end is flush with the cover for end
terminations or perpendicular to cover for midspan
terminations. (See Figure 6)
3. Place the cable/cover sub-assembly between the guides
on the locator plate, cover side down. (See Figure 7)
4. Position and orient connector body, contacts down,
over the cable/cover sub-assembly, aligning cover with
the body. (See Figure 7)
5. Lower the PRESS HANDLE firmly to complete the
Cable/Connector Assembly. (See Figure 8)
6. Raise press handle and remove completed assembly.
Visually inspect to ensure that:
a. Cover is fully seated and parallel with the body.
b. Cable is properly aligned with the cover grooves.
c. Cover retaining devices on the body are flush with
the cover end.
Procedures for
Adjusting Shut Height
Shut height settings are guidelines for proper termination
depth.
The shut height adjustment is made from the base of the
assembly press without the locator plate and platen in
place.
1. Place the shut height gauge, 3436-1A, across the press
base. (See Figures 2 and 3)
2. Lower the handle of the press until the handle casting
makes contact with the press casting. (See Figure 2)
3. Rotate the shut height adjustment feature until the
bottom of the shaft contacts the desired position on the
gauge.
4. Install the locator plate and the appropriate platen on
the press. The platen should be positioned parallel with
the connector body and cover.
NOTE: See the chart on page one for the appropriate shut
height setting.
