Adapted backshell keeps big bundles
screened
KEC has adapted a miniature 37-way Inotec D-type backshell to accommodate a heavy-duty cable assembly that would not normally fit a standard D backshell.

The KC 2300 is a series of high performance EMC backshells that provides excellent protection including Tempest levels but is reduced in sizeand weight from other backshells in the range.
Band clamp system a first for EMC backshells
New EMC circular backshells use a re-workable band clamp device that has only been used in general engineering and not for screen termination of high quality, professional electronic components.
This was required to fit a standard D-type connector in order to simplify interface requirements, but there were no standard backshells with a sufficiently large cable entry.
The solution chosen was to split the cable bundle into three smaller bundles and use a multi-entry D backshell.
The problem remained as to how this could be achieved while retaining EMC integrity.
When dividing the cable into three smaller bundles great care was taken to share the overall screen between the three.
Each of the legs was then over-braided, at the same time ensuring that the braid encircled the shared section of overall screen.
In this way full continuation of the 360-degree screen was achieved.
Each leg was then jacketed with a heat-shrink tube and the screened and jacketed leg then fully terminated with a crimp flange and ferrule into an Inotec multi-entry backshell.
A three-branch boot is used to 'tidy up' the three-way split in the overall cable.
This special product design can now be provided in two- or three-branch format for oversize cable bundles and is an example of the growing use of the specialised EMC cable assembly facility at KEC.
