114-13172
The front and rear bellmouths are caused by the extrusion of metal during crimping and must be within the
range specified in Figure 3.
8. Cutoff Tab and Burr
The cutoff tab and burr resulting from the contact being cut from the carrier strip must be within limits to
allow the contact and optional TPA to be fully inserted and seated in the housing. See Figure 3.
9. Flash
The wire barrel flash at the bottom of the wire barrel results from applied crimp pressure and must be
within the dimension provided in Section X-X of Figure 3.
10. Twist and Roll
There shall be no twist, roll, deformation, or other damage to the mating portion of the crimped contact
that will prevent proper mating. See Figure 3.
B. Straightness
The force applied during crimping may cause some bending between the crimped wire barrel and the
mating portion of the contact. Such deformation is acceptable within the following limits.
1. Up and Down
The crimped contact, including cutoff tab and burr, shall not be bent above or below the datum line more
than the amount shown in Figure 4.
2. Side to Side
The side-to-side bending of the contact may not exceed the limits provided in Figure 4.
NOTE
Periodic inspections must be made to ensure crimped contact formation is consistent as referenced.

3.5. Assembly
A. Crimped Contact Insertion into Housing
The crimped contacts must be inserted in the back of the housing and snapped into place. Install the
contact so the wire barrel is facing the housing latch. When fully inserted, the locking lances will engage
Rev W2

114-13172
the housing and prevent backing out during mating of the connector. After inserting contact into housing,
pull back lightly on the wire to ensure contact is fully seated. See Figure 5.
B. TPA Installation
For applications requiring the use of a TPA device, TPA-compatible contacts and housings must be
employed. The TPA device will not work with standard contacts and housings. Once all the TPAcompatible contacts have been inserted, the TPA device may now be installed. The TPA must be oriented
with the teeth facing the wire entry openings of the housing, the radius surfaces of the teeth lying on top of
the wires and the latches aligned with the raised ledges around the perimeter of the housing. Then the
TPA must be inserted so that the teeth enter the housing contact cavities over the wires and the locking
latches engage the housing ledges. There should be an audible and tactile “click” as each latch is
individually engaged.

3.6. Strain Relief and Wire Dress
If required, wires can be bundled together and supported with cable ties. Wires must not be stretched or
confined in any way that would restrict the floating action of the contacts. Therefore, the wires must remain
perpendicular to the connector and avoid an excessively sharp bend radius. The minimum distance for the
cable tie, measured from the wire end of the connector to the cable tie is shown in Figure 6.

3.8. Wire Bend Radius
TE Engineering recommends that individual cables should be dressed to a bend radius of at least ten times the
cable outside diameter. Likewise, cable bundles should be dressed to a bend radius of at least ten times the
diameter of the bundle.
3.9. Panel Cutout
VAL-U-LOK Series Connector panel cutouts shall be as indicated in Figure 8. No mounting hardware is
required. The plug housing features flexible mounting tabs for insertion into the panel. Push the plug connector
through the panel - in the same direction as the cutout was made - until it snaps in place.
3.10. Header Assemblies
The pc board right-angle and vertical header assemblies are supplied with pre-installed contacts that have
right-angle or vertical solder tines. They are designed to mate with connectors that have precision formed,
crimp-type contacts inserted into 2- through 24-position housings. The vertical header assemblies are soldered
to the pc board with or without pegs. See Figure 1.

3.13. PC Board Header Assembly Placement
CAUTION
The header assemblies should be handled only by the housing to prevent deformation or other damage to the solder tines.
A. Manual Placement
Align the header assembly solder tines with the appropriate holes in the pc board. Start all solder tines
into the board, then press on the header until it seats on the pc board.
B. Robotic Placement
The robotic equipment must be adjusted to feed, pick up, and place the headers on the pc board with an
accuracy of 0.25 mm. The header assembly datum surfaces detailed on the customer drawing will ensure
correct placement of the header. For information on robotic equipment, see Section 5, TOOLING.
3.14. Soldering
A. Flux Selection
Contact solder tines must be fluxed prior to soldering with a mildly active, rosin base flux. Selection of the
flux will depend on the type of pc board and other components mounted on the board. Additionally, the
flux must be compatible with the wave solder line, manufacturing, health, and safety requirements. Call
the Product Information phone number at the bottom of page 1 for consideration of other types of flux.
Some fluxes that are compatible with these header assemblies are provided in Figure 11.

C. Cleaning
After soldering, removal of fluxes, residues, and activators is necessary. Consult with the supplier of the
solder and flux for recommended cleaning solvents. The following is a listing of common cleaning solvents
that will not affect the header assemblies for the time and temperature specified. See Figure 13.
DANGER
Consideration must be given to toxicity and other safety requirements recommended by the solvent manufacturer. Refer to the
manufacturer's Material Safety Data Sheet (MSDS) for characteristics and handling of cleaners. Trichloroethylene and
Methylene Chloride can be used with no harmful affect to the header assemblies; however TE does not recommend them
because of the harmful occupational and environmental effects. Both are carcinogenic (cancer-causing) and Trichloroethylene
is harmful to the earth's ozone layer.
