Product Data Sheet

Amphenol® Universal “Header Assembly” for

Flex Print/PC Board Mounting

No. 169-3

Mounts to all MIL-DTL-38999

and MIL-C-26482 Connectors

The use of connectors with printed circuit

termination is rapidly gaining popularity

due to the rise of high volume, vapor

phase or wave solder manufacturing

processes. Termination of this style of

connector to flex print or a printed circuit

board represents a major cost in the

manufacturing process for users. When

adding flex or printed circuit board assem-

blies to an expensive filter or filter/transient

protection connector, the total cost of a failed solder joint, a bent pin, or an

unanticipated electrical failure becomes prohibitive. The universal header

assembly from Amphenol will provide for easy separation of the connector

from the board on these occasions.

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 connec-

tor to the panel; the rear flange would be used to mount the header assem-

bly. 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-C-26482 connectors without special alterations. They

are of similar dimension as the flange of the mounting connector and would

be approximately .185 inches (4.70 mm) thick.

Incorporates a Shorter Pin/Socket Contact

The heart of the header assembly is a short pin/socket contact. The tail of

the contact would accommodate standard through-hole diameters and

thickness of the flex or printed circuit board materials. The socket is imbed-

ded in the molded material, making electrical engagement with the printed

circuit tail of the connector.
