Components for crimp technology, cable clamps and blind plugs

The correct assembly of shielded cables is a crucial criterion for electrical and mechanical functionality of HF-shielding connector hoods as well as for direct cable entries and passages in shielded terminal devices.  The connection between a connector hood and its cable and cable shield in particular has to comply with a number of essential requirements:
  • A low-resistance connection between cable shield and hood with a constant performance over long periods of use as well as under mechanical stress.
  • A gap-free HF-sealing of the cable entry.
  • Traction and torque relief with high retention forces remaining operative even in harsh conditions.
  • An easy, efficient and economic assembly.
By developing the crimp flange technology Inotec has focused on this critical interface in particular and offers its customers an optimal solution for every cable type, appropriate mounting tools included. Special device configurations or the use of individually assembled cables may sometimes require a traction relief to be realized with a conventional cable clamp technique. For those cases Inotec has also developed appropriate components fitting to the double-dovetail cable entries of the HF-protecting Inotec full metal hoods. The operational reliability of an entire application depends decisively upon a cable-specific matching of the components and assembly tools. For this reason the customer- and cable-specific determination and definition of the assembly parameters is a crucial part of the Inotec offer and ensures a safe, robust and reliable cable assembly.

Adaptors for MIL-standard circular connectors

The original crimp flange technology developed by Inotec with its unique 360° shield contact may also be integrated in other standardized circular connector systems. Especially in military applications, connectors have to fulfill extreme requirements in terms of EMC, robustness and reliability. For this reason, Inotec is offering special crimp flange adaptor parts for MIL-standard connectors. Due to their particular design with a sealing flange for shrink tubes they even allow an IP67 sealing of the crimped area.

All adaptors are produced according to the cable-specific crimp definition and may be customized for special applications.

 

Cable feedthrough with integrated crimp flange

Interconnection design for machine tools, apparatus constructions and also for plant engineering often requires complex configurations in low quantities. For this reason, devices are often connected by a direct cable feedthrough instead of plug-in connectors. Especially for this kind of application, Inotec has combined the crimp flange technology with the principle of single-piece cable gland. Available in wrench sizes starting with M8, these components provide an extremely robust feedthrough with a high level of shielding and an optional IP67 sealing with an additional shrink tube.

All adaptors are produced according to the cable-specific crimp definition and may be customized for special applications.
 
 
Advantages of the crimp flange technology
  • Low shielding or transition resistances by 360° contacting of the cable shield
  • High traction and torque resistance, typically even above the maximum tensile strength of the cables
  • No compression of the cable cores, twisted wires are not “untwisted” by compression
  • Fast, reliable and repeatable assembly process
  • HF-sealing interface to the connector hood with the unique dovetail geometry
Alternative components for cable and shield connection
