Abstract

Disclosed is a card edge connector using slotted flexible circuits to make electrical contacts. A cut-away view of the slotted flexible circuit used in the connector is shown in the figure. The flexible circuit 31 is made of a piece of polymer film 32 patterned with metal lines 33. There are slots 36 on the polymer film 32 between the contact portion 37 of the metal lines 33. The flexible circuit 31 is formed into a double-omega shape before it is placed into the connector housing. The specially formed spring 41 is placed behind the polymer film 32 to secure the flexible circuit inside the connector housing. The fingers 43 on the spring 41 will force independently the contact portion 37 of the metal lines 33 toward the connection pads on a card to be plugged into the connector.

Card Edge Connectors using Slotted Flexible Circuits

      Disclosed is a card edge connector using slotted flexible
circuits to make electrical contacts.  A cut-away view of the slotted
flexible circuit used in the connector is shown in the figure.  The
flexible circuit 31 is made of a piece of polymer film 32 patterned
with metal lines 33.  There are slots 36 on the polymer film 32
between the contact portion 37 of the metal lines 33.  The flexible
circuit 31 is formed into a double-omega shape before it is placed
into the connector housing.  The specially formed spring 41 is placed
behind the polymer film 32 to secure the flexible circuit inside the
connector housing.  The fingers 43 on the spring 41 will force
independently the contact portion 37 of the metal lines 33 toward the
connection pads on a card to be plugged into the connector.  The
slots 36 on the polymer film 32 will help to create a displacement of
the contact portion 37 of the metal lines 33 large enough to ensure a
reliable electrical contact.  The flaps 38 on the polymer film 32 are
for aligning the card to the right contact position when the card
which has corresponding alignment holes is in the connector.
