Feed-Through Has Polyterminal Feature 
IIIII 
STANDARD TERMINAL 
The problem: Standard bifurcate terminals require 
a relatively large amount of solder for multiple con-
nections, afford no visible inspection for connection 
integrity, and frequently suffer bond deterioration 
during changes to terminal connections. 
The solution: A feed-through connector featuring 
individual solder pots in the polyterminal side. 
How it's done: A polyterminal is designed as a 
feed-through to accommodate a single lead on one 
side and multiple leads on the other. The body of the 
polyterminal is splined for press fitting into a support-
ing member. The multiple terminal side is designed 
with from two to six individual solder pots that per-
mit individual connection or disconnection of the 
separate conductors. Changes in circuitry are accom-
plished without disturbing other connections because 
they are not remelted. The individual solder pots pro-
vide good connections with relatively small amounts
POLYTERMINAL 
of solder and permit precise visual inspection of each 
bond. 
Notes: 
1. This design provides a friction mechanical bond 
to position the conductors prior to soldering—a 
valuable aid in assembly line work. 
2. This polyterminal would improve any circuitry cur-
rently employing bifurcate terminals. 
3. Inquiries concerning this innovation may be di-
rected to:
