Compact Coaxial Connector for Printed Circuit Adds Reliability 
The problem: Connecting a coaxial cable to a 
printed-circuit board where the cable terminates. 
Coaxial connectors generally used are bulky and 
heavy, so that the connection to a printed-circuit 
board may be of doubtful reliability. For high-
reliability equipment, an improved device is needed 
to minimize these problems. 
The solution: A compact coaxial connection that 
utilizes soldering and welding techniques and elimi-
nates standard coaxial connectors for permanent 
connections. 
How it's done: in place of a coaxial connector 
normally used, a U-shaped pin having a welded 
crossbar is utilized. The outside insulation of the 
cable is stripped back and the shielding is soldered 
to the U-pin, thus providing the ground contact. 
A connection is made to the inner conductor by 
soldering to a single pin. After connections have been 
made, the entire device is enclosed in a rigid 
epoxy resin block that provides structural strength and 
protects the connections from damage.
Notes: 
1. This method eliminates coaxial connectors and is 
most useful where the coaxial cable is to be 
permanently connected to a printed-circuit board. 
Applications could include aerospace equipment 
and aviation electronic devices where high reliabil-
ity and low weight are important.
