HE308-35VA29/03/0114:55Page2 Band Backshell HE 308-35 for MIL.DTL-38999 I & II connectors TV-35 * Mass continuity assured by the band between cable braid and backshell * Very high level of cable retention assured by the band on the braid * Easy cabling process * Very good sealed when terminated with a straight or right angle heat-shrink DESCRIPTION MAIN CHARACTERISTICS for MIL.DTL-38999 III connectors molded piece Band backshells were originally developed for military applications. They provide facility by using due to the band which assures very high quality level (tightness, wire retention force, EMI/RFI protection...) The HE 308-35 is usable with all JT/ LJT connectors which accept rear accessories (MIL-DTL-38999 Series I&II). * Provides an high performance EMI/RFI protection * Only one tool is needed to set up the band on the backshell The TV-35 is usable with all TV connectors which accept rear accessories (MIL-DTL-38999 Series III). * Available with different cabling chamber lengths to meet your requirement E 118/A APPLICATIONS Heavy duty EMI - RFI band backshell * These backshells are suited to harsh environment / military / aeronautic use. CHARACTERISTICS HE308-35VA29/03/0114:55Page3 Application tools & process 1. Prepare Cable Braid for termination process (Figure 1). 2. Push Braid forward over Adapter Retention Lip to the Adapter Incline Point (or .4" [10.2mm] minimum braid length). Milk Braid as required to remove slack and insure a snug fit around the shield termination area (Figure 2). SHIELD TERMINATION CLAMPING PROCESS: (Figures 4 thru 8): NOTE: To free Tool Handles, move Holding Clips to center of Tool. 3. Prepare the Band in the following manner: 4. Squeeze Gripper Release Lever and insert Band into the front end opening of the Tool. (NOTE: Circular portion of looped band must always face downward.) IMPORTANT: Due to Connector/ Adapter circumference, it may be necessary to prepare the Band around the Cable or Retention Area. 5. Aligning the Band and Tool with the Shield Termination Area, squeeze Black Pull-Up Handle repeatedly using short strokes until it locks against Tool Body. (This indicates the Band is compressed to the Tool Precalibrated Tension). A. Roll Band through the Buckle Slot twice. (Bands must be double-coiled.) NOTE: If alignment of band and shield is unsatisfactory, tension on band can be relaxed by pushing on slotted release lever on top of tool. Make adjustments as necessary and again squeeze black pull-up handle. B. Pull on Band until Mark ( ) is within approximately .250 inch (6.4mm) of Buckle Slot (Figure 3). The Band may be tightened further if desired. 6. Complete the Clamping Process by squeezing the Gray CutOff Handle. NOTE: Prepared Band should have ( shown in Figure 3. ) Mark visible approximately where 7. Remove excess Band from Tool. 8. Inspect Shield Termination. ADVISE: Coupling will be ensured if thread locking "Lactite 243" is used on connector. 2 DIMENSIONAL CHARACTERISTICS HE308-35VA29/03/0114:55Page4 Chart I Size C diam. +0.1/-0 (mm) 09 11 13 15 17 19 21 23 25 C1 diam.
