Field:


Assembly of flat cables in electronic equipment, wherein the flat cables comprise a PCB paddle card element on each side and wherein the flat cables are stacked together over the PCB paddle card elements.

Problem:


When routing or laying out multiple flat cables stacked together and needing to fold them, the cables on the inside of the fold always cover a smaller distance than on the outside. To maintain a flat pack of cables, the length of each individual cable strip needs to be adjusted to its correct length. In this case, it is assured no stress is created at any point in the connectors or cables. During the assembly process of a cable harness, it is preferred to have as little variation in length as possible and in case of flat cable, to be able to terminate in a straight orientation. By using equal length strips of cable, the cable harness can be assembled easily in a straight configuration and proper folding will assure a right-angle solution without bulging the cables or putting stress on the connections.

The background of the invention is in support of the Twin Axial cable technology. This cable supports high speed data transmission with the unique routing possibilities of a flat cable. This offers opportunities to create high speed, high signal density solutions.

A very cost effective way of creating high speed assemblies is to solder the twinax cable to a PCB paddle card. This paddle card can then mate to a card edge connector. The design of such a paddle card can easily be customized and optimized for performance. A soldered connection however is not a very strong mechanical connection. For long term reliability it is not allowed to have a significant force on the solder joints. This is prevented by some form of strain relief and cable routing such that no stress is put on the joints.

Although the cable...
