MICRO COAXIAL CONTACTS AND MODULES USER’S MANUAL: SECTION 2 VIRGINIA PANEL CORPORATION MICRO COAXIAL ITA CONTACT ASSEMBLY 50 OHM • PART # 610 141 104 FOR RG 316DS Dimensions shown: [millimeters] TOOLS REQUIRED Soldering Fixture, Part # 910 121 178 Inspection Depth Gauge, Part # 910 121 180 inches [10.67] .42 OUTER INSULATION BRAID Figure A. Strip outer insulation to dimension shown. ASSEMBLY INSTRUCTIONS [6.35] .25 1. Strip the outer insulation of the wire (Figure A) and tin the braid. 2. Perform second strip (Figure B). 0.17” will be trimmed from the front of the wire to remove any solder build up. 3. Solder wire center conductor into contact center conductor, and clean (Figure C). NOTE: Contact center conductor and dielectric must touch (Figure D). 4. Calibrate the Inspection Depth Gauge, Part # 910 121 180 (Figure E), by loosening the dial face retaining screw until the dial face allows itself to be turned. Insert the calibration plug into base of gauge. While keeping constant pressure on the plug, adjust the dial by rotating it such that the pointer points to “0”. Re-tighten retaining screw. Adjust locating markers to “5” and “95”. 5. Slide the shield conductor over the center conductor and check the .136″ ± .005 dimension (Figure F) by using the inspection depth gauge. Insert contact into gauge until contact stops. If the pointer measures between “5” and “95”, go to the next step. If the pointer measures below the “95” marker, slide the shield to adjust. If the dimension measures above the “5” marker, cut the strip off and repeat steps 1-5. DIELECTRIC [2.29] .09 [1.52] .06 [4.32] .17 WIRE CENTER CONDUCTOR Figure B. Second strip will remove any solder build-up. CONTACT CENTER CONDUCTOR WIRE BRAID SOLDER FIXTURE Figure C. Soldering Fixture, Part # 910 121 178. NO GAP PERMISSIBLE DIELECTRIC CONTACT CENTER CONDUCTOR SOLDER Figure D. Ensure contact center conductor and dielectric touch. 6. Solder the shield and clean (Figure G). 7. Use the inspection depth gauge to verify the .136″ ± .005 dimension as shown in step 5. If the dimension is out of range, repeat steps 1-7. Figure E. Inspection Depth Gauge, Part # 910 121 180.
