Honeycomb Strain Relief CFU

Available from igus is a new, unique strain relief for e-chains: the honeycomb strain relief CFU. The strain relief system replaces commonly used cable tie-wraps and other strain relief solutions.

The older version of the strain relief required users to arrange each cable separately in the energy chain. In the new solution, the cables and hoses are simply inserted into the honeycomb and then closed. This way, the outer walls of the honeycomb cavities lie gently and uniformly around the cables.

The honeycomb system can be assembled in seconds, and it is also extremely flexible, allowing new cables can be inserted or replaced by hand. The newly improved CFU combines a compact design and allows for simple and flexible filling. With this new CFU, users can reduce assembly and engineering time by about 80 percent.

Due to the flush finish with the e-chain mounting bracket, the new CFU can be used in both unsupported and gliding applications. The design allows for easy scaling for individual chain widths. Cables are simply inserted into the vertical rows of the CFU, the system is closed and then screwed at the top.

Optional clips at the side plates connect energy chain and strain relief. With the strain relief system, the designer can schedule the chain and strain relief before they know the exact cable assignment. This can also be easily changed in the later stages.

The system is being developed for the E4.1L chain. Together with the new separator system for a custom-made interior separation, the honeycomb strain relief makes the E4.1L the easiest to fill e-chain on the market.
