ABSTRACT:
According to the present invention a one-piece molded strain relief structure for an electrical conductor is provided which includes a body portion having a tortuous path directly molded therein for receiving and guiding the conductor. The tortuous path includes an entrance and exit and further includes at least two changes in direction therealong. In a preferred embodiment the tortuous path is substantially S-shaped and is adapted to receive an electrical conductor having a flat cross section. The tortuous path is configured to confine the flat electrical conductor in a first orientation adjacent the entrance thereof and to cause twisting of the conductor to a second orientation angularly disposed from the first orientation as it approaches the exit thereof. A guide is provided adjacent the exit for imparting a sharp bend in the conductor as it passes therefrom.
