DIMENSIONS ARE IN INCHES [MILLIMETERS].

ALL DIMENSIONS ARE SUBJECT TO CHANGE.

Reliable, solderless connections from connectors

to backplanes started with solid press-in technology.

Although these are still used today, concerns about

board damage led to the use of compliant press-in

technology. This technology allows the connection to

be made through compliance of the contact termination

along with printed circuit board hole deformation.

Although risk of damaged printed circuit boards and

backplanes is lessened, damage can still occur due to

relatively high insertion and extraction forces.

The next step in press-in technology is a highly

reliable connection between the contact termination and

backplane that is accomplished with reduced insertion

and extraction forces. This eliminates risk of printed

circuit. board and backplane damage. This technology

exists today with Positronic Bi-Spring Power Press-in

termination.

BI-SPRING POWER PRESS-IN TERMINATIONS

The Next Evolution In Compliant Technology. Fully Compliant, Fully Reliable.

Average insertion and extraction forces of size 16 contacts are 22N [5 lbs.] per

contact and do not produce stresses in printed circuit boards and backplanes that

can occur with higher insertion forces. These stresses can cause board warpage

and hole damage.

Connector systems utilizing Bi-Spring terminations use mounting screws to secure

the connector to the printed circuit board or backplane. Stresses that occur during

coupling, uncoupling or shock and vibration of systems are not transferred to the

printed circuit boards or backplanes through the press-in connection. The electrical

integrity of the connector to board interface is maintained; this is particularly

important in power applications. Bellcore GR1217 details a preference for mounting

hardware when using press-in terminations.

Size 16 Bi-Spring terminations are designed to meet the performance requirements

and hole diameters as listed in the internationally recognized specification

IEC 60352-5.

Lower insertion and extraction forces eliminate the need for expensive pressing equipment.
