The multiplication of data in electronic systems could have disastrous results if the impact of the cross talk was not anticipated. Under an electromagnetic perturbation (EMI, RFI or EMP), the cable’s conductor acts as antennas and picks up the radiated signals. The reception of this interference surely impacts the initial signal integrity.
Nowadays, data rate is exponentially increasing and high-speed protocols are omnipresent. A proper shielding appears as a key part of the design. The most efficient shielding method is to enclose the cable in a metal braid which is then grounded to one or both ends of the cable thanks to the network nodes: The connectors and backshells.
Backshell as a rear part of NICOMATIC connector MIL-DTL-83513G is used to secure the cable and to avoid stresses on the soldered/crimped part of the contact. It also shields against electrical interference (EMI/RFI protection) with Transfer Impedance (Zt) under 200mOhm from10 KHz to 400Mhz. Made of Aluminium 6061 with chemical nickel finishing, it protects from mechanical damages.
Back chimneys are designed in a shape of an ellipse, fully compatible with Band-it type system. Bands and clamping hand tools are available on our website. Openings allow to fasten the wires with a Serflex system and also to ground the shielding of twisted pair cable.
There are 2 available designs of our backshells, split and mono.
The split backshell presented in the video is fully compatible with all Nicomatic connectors, and designed as a two-piece shell. Fixing hardware is mounted on the connector and the locking of the two parts of the shell does not interfere with the harness which is made independently in a previous stage. It results an easy and quick assembly.
Mono backshell is fully compatible with all Nicomatic connectors. Lighter, smaller and cheaper it is a smart and cost effective solution for series stage. Note that fixings are captive and integrated to the backshell.
R&D department has been working hard on the backshell topic, especially How to use the ergonomics to limit risks and save time during the cabling operation. Don’t hesitate to contact email@example.com
