Connector for Multiple or Overall Shielded Cables Grounded With One Compression Cushioned Shield-Kon(R) Connector A special feature is the smooth, heat stabilized nylon insulator which acts as a cushion to protect conductor insulation from abrasion. This molded blue nylon insulator is wedge-fitted to the hard brass inner collector rings. The Shield-Kon Connector System for multiple-conductor shielded cable is based on the principle of cold swaging. It utilizes a two-piece compression connector colour-coded to match the proper die. The connector consists of a hard brass collector inner ring with a tough, smooth insulator and a soft copper compression outer ring. Each set of rings and matching installing die will connect a minimum of 5 shielding braids with one ground wire. The maximum number of braids is limited only by the space between the inner and outer rings. The design advantages are: 1. Positive selection of inner and outer sleeves and installing die by a complete colour-coded system. 2. A more reliable grounding termination because only one ground wire connection is made - conventional daisy chain jumper method is eliminated. 3. Smaller, more compact bundle is easy to inspect. 4. Only one ground wire is required, however additional ground wires may be used if needed. 5. Smooth insulator protects conductor insulation. 6. With one stroke of the tool, the interlace die will produce a 360 compression uniformly securing all individual shields around the connector. Overall Shield and Multiple-Conductor Shield Particularly useful in small space applications as in this 90 connector. The three different ring techniques ground the multiple conductor shields as well as the overall outer braid.

After shielding is extracted, attach ground wire(s) to connector pin and place between collector and compression rings. Colour-coded die will make a 360 compression in one stroke.

Warning: Never install on energized wire. 234 Outer Compression Ring Outer Insulation Folded Back Braids Conductor Insulation Grounding Wire (Stripped and Hairpinned) Trimmed Braid Pigtails Inner Collector Ring Double Fold Method Grounding wire can be inserted from front or back Connector for Multiple or Overall Shielded Cables Grounded With One Compression Multi-Shielded Cable Connector Installation Procedure 1. After overall insulation is removed to expose shielded cables, each conductor must be freed from the shielding braid. The Thomas & Betts lead extractor tool simplifies this operation by pushing the inner conductor through an opening in the shielding braid. The braid is then folded back until all conductors are freed. See Lead Ext. Table, page 235. 3. Position outer compression ring over the flattened shielding braid, locating it over the center of the inner collector ring. Braid may be trimmed even with the edge of the outer compression ring before or after compression. Ground wire or wires may be inserted between the outer compression ring and the shield prior to compression. 2. Flattened shielding braids are evenly distributed around the periphery of the inner collector ring. 4. Selection of compression dies is determined by colour code on rings. The dies are colour coded to match the rings. The appropriate dies are easily inserted or removed by depressing die locking button shown. 6. Completed installation of the "single fold"-"fold forward" method typifies the reliability, compactness and neatness which is obtained with all Thomas & Betts recommended installation methods. * Easier and quicker to install - one compression grounds all conductors simultaneously. * Improved reliability - multiple connector errors eliminated. * Smaller, less bulky bundle diameter - eliminates individual connectors and daisy chained jumpers. * Reduce installed cost - fewer parts, less installation and inspection time. * Smooth nylon insulator acts as cushion to protect conductors. Warning: Never install on energized wire. 5. The prepared cable is placed in the installing die and compressed. Tool operates on hydraulic power output developing 9800 200 psi operating pressure. 235 Connector for Multiple or Overall Shielded Cables Grounded With One Compression Inner Collector Ring Connectors for Shielded Cable .600 .015 Colour-coded marking Outer Compression Ring Installing Die Cat.
