TOR-SPRING™ – A Breakthrough in EMI/RFI Cord Grip Design and Installation

Original EMI/RFI Cord Grip designs feature one or more internal metal rings to which the cable's braided shield is attached. Because the braided shield must be cut, removed and then carefully positioned around or between these rings, the EMI/RFI Performance of field installed Cord Grips have been inconsistent and dependent on the installer's experience, skill level and willingness to follow installation instructions. Conta-Clip's new TOR-SPRING™ Cord Grips have been especially developed to eliminate the installation and performance uncertainties associated with traditional design EMI/RFI Cord Grips. Their advanced design represents a significant technological breakthrough overcoming all installation shortcomings associated with traditional ring design Cord Grips, while providing more consistent EMI/RFI Performance.

Installation of Traditional EMI/RFI Cord Grips

Installation of traditional design, EMI/RFI Cord Grips onto shielded cables is difficult and time consuming. Both the cable jacket and the shield must be cut and removed at the Cord Grip's attachment point. Next, the braided shield must be carefully separated and positioned around one or a pair of metal rings. If this procedure is not followed exactly, the Cord Grip 's EMI/RFI Performance can be diminished or inconsistent. Because the braided shield is cut away and removed at the Cord Grip attachment point, continuance of EMI/RFI Performance to the cable termination point is not provided. Application of a secondary tubular braid to this length of unshielded cable is required to ensure the system's EMC Integrity.

Installation of TOR-SPRING™ Cord Grips

Conta-Clip's unique TOR-SPRING™ EMI/RFI Cord Grip Design featuring the toroidal spring/tapered ring principle ensures a controlled and precise installation onto shielded cables. Installation is simplified and installation time is significantly reduced because only the cable jacket needs to be cut and removed at the Cord Grip attachment point. The cable's braided shield remains intact and is eliminated from the installation procedure. Since the braided shield extends to the termination point, continuous EMI/RFI Performance is guaranteed.

Shielded Cable Preparation

Two optional methods of cable preparation are used when installing TOR-SPRING™ EMI/RFI Cord Grips. The preferred method of shielded cable preparation involves cutting and removal of a small 10mm (0.39in.) segment of cable jacket at the Cord Grip attachment point (See Figure# 3). The second method involves stripping and removing the cable jacket from the Cord Grip attachment point to the end of the cable (See Figure# 4).

The cable preparation method used will be determined by the outer diameters of the cable jacket and braided shield and the inner diameter of the (2) available Cord Grip Styles A and B; and, whether it is possible for the cable to fit through the TOR-SPRING™ Cord Grip's Tapered Rings. If the cable dimensions are such that the cable will pass through the Cord Grip, then only a segment of the cable jacket needs to be removed. Conversely, if the cable will not pass through the Cord Grip's Tapered Rings, the cable jacket must be fully stripped from the Cord Grip attachment point to the end of the cable.
To determine which cable preparation method to use: follow the steps under How to Select/Specify TOR-SPRING™ Cord Grips.

TOR-SPRING™ Cord Grip Installation Instructions (Non-threaded mounting holes)

  1. Drill or machine required clearance hole into enclosure/housing.

  2. Install TOR-SPRING™ Cord Grip into Mtg. Hole.

  3. Secure with either special PG Size EMI/RFI Locknut or standard Nickel Plated Locknut and torque to recommended torque value (See Page 69).

  4. Unscrew Dome Nut Remove Sealing Insert (2),Tapered Rings(5A) and (5B) and Toroidal Spring (6). (See #5)

  5. Slide Dome Nut (1) and Sealing Insert(2) onto prepared cable.

  6. Install Tapered Ring (5A) with tapered side facing enclosure/housing over cable's exposed braided shield.

  7. Install Toroidal Spring (6) over cable's exposed braided shield.

  8. Install Tapered Ring (5B) with tapered side facing Toroidal Spring (6) onto cable's exposed braided shield.

  9. Insert cable with installed parts into the Cord Grip Body (3).

  10. Feed cable through Cord Grip and adjust length inside enclosure housing as required to reach termination point.

  11. Tighten Dome Nut (1) to recommended torque value.

Note: When TOR-SPRING™ Cord Grips are mounted into a threaded mounting hole, torque Cord Grip Body to the recommended torque value. Follow TOR-SPRING™ Cord Grip Installation Instructions Steps 4 - 11.
