Universal “Header Assembly”
for flex print or PC Board
Mounts to all MIL-DTL-38999 and
MIL-DTL-26482 Connectors
Termination of PC tail connectors to a flex
print or a printed circuit board represents
a major cost in the manufacturing process
for users. When adding flex or printed
circuit board assemblies to an expensive
filter or filter/transient protection connec-
tor, the total cost of a failed solder joint,
a bent pin, or an unanticipated electrical
failure becomes prohibitive. The universal
header assembly from Amphenol provides
for easy separation of the connector from the board on these occasions.The
header assembly is comprised of a short pin/socket contact. The tail end of
the contact is soldered to the through hole of the flex or printed circuit board.
The socket is embedded in the insulator, making electrical contact with the
printed circuit tail of the connector.
Header Assemblies Provide Cost Savings
Incorporation of the header assembly provides the user with time and cost
saving potentials. These header assemblies can be vapor phase or wave
soldered to flex or printed circuit boards prior to the receipt of the EMI/EMP
connector. Headers can be installed to standard connectors, allowing for
electrical testing that would adversely affect the sensitive diodes, MOV’s or
capacitors in the EMI/EMP connectors. Expensive connector assemblies
can be easily removed from and reattached to the header assembly as the
manufacturing process dictates.
Mounting Applications
Shell modifications are recommended, but are not necessary. The header
assembly can be attached to connectors with standard flange placement
or directly to the circuit board. The ideal application would involve either
a single flange moved all the way to the rear of the connector or a double
flange. Cinch nuts can be installed in either flange to allow easier mounting
to the panel or the header assembly. The forward flange would mount the
connector to the panel; the rear flange would be used to mount the header
assembly. Various types of captivated or loose attaching screws can be
utilized for unique applications.
Amphenol universal headers are slotted to allow mounting to all series of
MIL-DTL-38999 or MIL-DTL-26482 connectors without special alterations.
They are of similar dimension as the flange of the mounting connector and
are approximately .185 inches (4.70 mm) thick.
