Abstract

Densely packed modules also have densely positioned input/output terminals. To increase the number of possible input/output terminals or the distance between them, additional pin connectors are clamped to the edge of the module.

Edge Connector for Electronic Modules

       Densely packed modules also have densely positioned
input/output terminals.  To increase the number of possible
input/output terminals or the distance between them, additional pin
connectors are clamped to the edge of the module.

      An example of the connectors is shown in Fig. 1.  Fig. 2 shows
a corner of the module with fitted connectors.  The edge connector of
Fig. 1 consists of a U-shaped clamp 1 which is pushed over the edge
of the module to make contact with a pad on the module.  In the
illustrated example, the lower end 2 of the terminal is bent to the
horizontal to facilitate soldering.  The distances between terminal
ends 2 may be increased by staggering them as shown by terminal 2a
drawn in dashed lines.  Fixing of the connectors to the edge of the
module is facilitated by punching them from a metal strip so that
they are bridge- connected by an upper strip 3 which can be broken
off after attaching the connector strip and soldering the connectors
to the respective pads of the module.  A portion of module 4 with
fixed connectors 5 is shown in Fig. 2.  This figure also shows the
well-known pin connectors 6 connected to pads 7.  The proposed
connectors may be fixed to all four edges of the module, thus
providing additional terminals for the module.
