EMI/RFI Band Application System For M85049/128 Shield Termination Bands

The termination of EMI/RFI shielding materials is a specialized science in today’s aerospace wiring systems. Application tooling is a critical factor in the overall performance of the wiring system components.

DMC has worked closely with the world's leading connector accessory manufacturers to develop the necessary tooling and accessories to meet the stringent demands of aerospace and defense system contractors.

The resulting products afford the user many benefits which include:

• COMPATIBILITY with all currently available termination bands and systems.
• RELIABILITY through the use of commercially proven components and tool design practice.
• QUALITY and REPEATABILITY which are assured by a tension-lock system.
• SERVICE AND CALIBRATION – All tools produced by DMC are adjustable, and may be easily recalibrated by the user. Also, expendable components such as cut-off blades are available for simple replacement by the user.
• LONG SERVICE LIFE – Properly maintained band application tools will produce thousands of reliable terminations.
• AFFORDABILITY – DMC tools continue to be the most cost effective method to produce reliable wiring system shield terminations.

Models are available for .250 in. (6.350 mm) and .125 in. (3.175 mm) wide bands from all current suppliers to M85049/128.

M85049/128 Shield Termination Bands are available in two distinct configurations, Stamped and Welded Buckles. The "Stamped Buckle" configuration is a low-profile style with a slot for the other end of the band to pass through. The "Welded Buckle" configuration is a folded style with a loop for the other end of the band to pass through.

ONE-STEP BANDING TOOL SYSTEM FOR "STAMPED BUCKLE" BANDS

DMC's One-Step Banding Tools are designated for M85049/128-3, M85049/128-4, M85049/128-7 and M85049/128-8 "stamped buckle" bands. These tools tension, bend, and cut the band. 

DBS-2100 is the .250 Wide Band Application Tool and meets the requirements of M81306/1-01.

DBS-2200 is the .125 Wide Mini-Band Application Tool and meets the requirements of M81306/1-02.

TWO-STEP BANDING TOOL SYSTEM FOR "WELDED BUCKLE" BANDS

DMC's Two-Step Banding Tools are designated for M85049/128-1, M85049/128-2, M85049/128-5 and M85049/128-6 "welded buckle" bands. These tools tension and cut the band and leave an extended cut off tab. The second step provides an extra level of security by utilizing a roll-over tool to bend the cut off tab over a full 180 degrees.

DBS-1100 & DBS-RO3 are the .250 Wide Band Application Tools and meet the requirements of M81306/2-01.

DBS-1200 & DBS-RO5 are the .125 Wide Mini-Band Application Tools and meet the requirements of M81306/2-02.

PROCEDURES FOR BANDING

Careful measurement should be made prior to installing the backshell. The outer jacket is then uniformly removed at a distance which would allow the braid to make a comfortable transition onto the backshell termination area. This dimension will vary depending upon the differences between cable and backshell diameters or other application dependent factors.

The braid is then trimmed to a length which will allow it to extend 1 inch past the backshell termination platform. Then the braid is carefully folded rearward to expose the wires which will be inside the backshell.

A sufficient number of wraps of self-vulcanizing tape (normally red in color) are applied over the wires to buildup a diameter slightly less than the inside diameter of the backshell. Care should be taken not to apply tension to the contacts located in the outer perimeter of the connector.

These layers of tape are followed by a minimum of one layer of Teflon tape which will prevent adhesion with the backshell and other components.

The backshell is then installed onto the connector, using a nonabrasive tool such as a strap wrench. The braid is then carefully moved from under the backshell. It is important to retain the woven characteristics of the braid during this step.

Use self vulcanizing tape or a preformed component to build up the area behind the backshell. It is important that the braid is supported in the transition from the backshell rear diameter to the natural diameter of the wire bundle. Leave approximately 1/8 inch spacing between the tape wrap and the backshell.

The braid is pushed into position over the backshell termination platform. Care must be taken to make sure the weave is uniform and no large “windows” are present. A shield termination band is then loaded into the tool. The band is then slid over the connector/backshell assembly into a position of alignment with the termination platform. Apply an adequate amount of pressure in line with the cable as it enters the backshell to allow the 1/8 inch space to be reduced to zero. The tool is then activated to the preset tension and the band terminated according to the individual tool's procedures.

For braided a non-jacket cable use fine point shears to trim the excess braid as close to the connector side of the bands as possible.

Do not leave any unsecured braid wires longer than 1/8 inch. Do not allow the trimmed wires to fall into 
any areas where they may present a foreign object damage hazard.

PROCEDURE FOR SPLICING

The jacket is present, and shield are cut and separated to expose the wires requiring service. Care must be taken to avoid damaging the insulation on internal wires. The required service is then completed.

The wire bundle is then protected by a few wraps of self-vulcanizing tape followed by 2–3 layers of teflon tape. An appropriate size split ring set is then selected and installed. One layer of teflon tape is applied over the split ring set to hold the halves in position while the next steps are being performed.

The braid is then overlapped across the split ring set. Be sure the braid ends protrude completely under the band in both directions.

Heat shrinkable tape is then applied over the splice. Where a jacketed cable is used, be sure the tape extends onto the jacket in both directions.
