Innovative wire connecting solution replaces manual splicing processes in harsh environments

12 September 2023

The C&K SpaceSplice series wire connecting solution from Litteluse, Inc., is designed to replace manual splicing processes in harsh environments. These connectors provide a standardized, easy-to-use, high-reliability solution manufactured to the highest standards.

The SpaceSplice connectors are a unique solution to wire-to-wire connection, designed to replace hand splice processes with a standardized solution that reduces labor time and is easy to use. It allows the connection of two wires using a D*MA crimp and removable contact technology. SpaceSplice is designed to accept the most relevant gauges, reduce cost and ensure that only the required wires are used.

Designed to meet the highest quality requirements, SpaceSplice is ideal for demanding wiring systems, including:

  • Military/aerospace applications like satellites,
  • Launchers and payloads,
  • Heater, thermistor and multilayer insulator (MLI) connections, and
  • Other harsh environment applications.

“The SpaceSplice connectors design provides a high-reliability solution that replaces manual splicingSource: Littelfuse, Inc.Source: Littelfuse, Inc. processes, offering a standardized alternative that is easy to use, reducing labor time and cost while increasing reliability," said Rémi Antoine, global product manager at C&K Aerospace, now part of Littelfuse.

The SpaceSplice series wire connecting solution, with its unique design featuring removable crimp contacts, provides the following benefits:

  • Employs removable, D*MA crimpable contact technology.
  • Allows for both manual and guiding-tool-assisted insertion.
  • Accepts the most popular cable gauges (AWG 20 — AWG 30).
  • Provides high radiation and temperature resistance.
  • Low residual magnetism and low degassing.
  • Compliant with European Space Agency (ESA/ESCC 3401/097) specifications.

How it works

The SpaceSplice wire connecting solution is available in a one-way series that connects two wires with a standard solution and a four-way series that is a stackable wire-to-wire connector with removable contacts, which can be beneficial in space applications where more than four ways are required.
