Abstract

Disclosed is a coiler that is attached to a flex circuit so that the coiler will coil the flex circuit when left in a free state. Fig. 1 shows the flex circuit that is restrained in a flat condition. If left alone, the flex circuit would coil itself up as shown in Fig. 2.

Coiled Flex Circuit

      Disclosed is a coiler that is attached to a flex circuit so
that the coiler will coil the flex circuit when left in a free state.
Fig. 1 shows the flex circuit that is restrained in a flat condition.
If left alone, the flex circuit would coil itself up as shown in Fig.
2.

      The coiler is made from a polymer that is coiled in the free
state.  It can be attached to the flex circuit by using adhesive or
mechanical means.  The flex circuit is much more flexible than the
coil%r, and when the two are joined together, the flex circuit will
conform to the coiler.

      It is desirous for the flex circuit to roll itself up out of
the way when it is not connected to the mating connector.  Using a
coiler attached to the flex circuit provides an inexpensive method of
accomplishing this task.
