Wire-to-Wire Splicing MiniSeal High-Performance, Immersion-Resistant Crimp Splices Product Facts n Immersion-resistant crimp splices are on QPL for MIL-S-81824 n MIL-Spec approval n Small size n Light weight n Insulation and strain relief n Easy installation Applications Product Selection Process MiniSeal wire-to-wire splicing products offer solutions for hundreds of aerospace and defense applications. These environment-resistant splices provide excellent reliability, long term performance, MIL-S-81824/1 qualification, and a low installed cost. 1. Determine the type of splice required. MiniSeal crimp splices consist of a plated copper crimp barrel and a separate, heat-shrinkable, transparent sealing sleeve. They can be used on a combination of wires, from 1:1 to 10:10. MiniSeal splices are one of the smallest, lightest, and most environmentresistant splices available. They preserve the electrical integrity of the splice by preventing the penetration of liquids and the resulting chemical and galvanic corrosion. n Stub (parallel) splice: 2 2 n Butt (in-line) splice: 2. Determine which crimp barrel plating is required: n n Tin plating, recommended for tin or silverplated wire Nickel plating, recommended for nickel-plated wire, or silver-plated wire in applications above 150°C [302°F]. 3. Calculate the size of crimp barrel required. Using the CMA/mm2 worksheet on the next page, calculate the total cross section to be spliced by adding the circular mil area (CMA) or square millimeters (mm ) of each wire. 2 Stub splice: Add the CMA or mm of all wires together. 2 Butt splice: Calculate each side separately (see example on the worksheet). Available in: Americas Europe Asia Pacific Table A provides the CMA of typical conductors. (Both CMA and mm give the same results, so choose either CMA or mm as your unit of measure for selection purposes and continue to use it for all your selection criteria.) n n n 4. Select the color code for the size crimp barrel required. Using Table B (page 8-23), select the crimp barrel—colorcoded red, blue, or yellow—for the CMA or mm you calculated. 2 Stub splice: Select the barrel that will accommodate the total cross section. Butt splice: Select the smallest barrel that will accommodate the largest CMA/mm2 required. (Refer to the example in the worksheet for a more specific description.) If the CMA/mm2 of the smaller side of a butt splice is too small for the size barrel required to fit the larger side, increase the CMA/mm2 —either by doubling back one wire (stripping the conductor twice the length you would ordinarily strip it and then folding it back) or by adding a filler wire. 5. Determine the type of sealing sleeve required. Some wire insulations will not fit in the holes of the sealing sleeve inserts, so be sure to compare the internal diameter of each hole with the outer diameter of the wire(s) you intend to insert in that hole. To create a reliable seal, place a maximum of two wires in any hole of the sealing sleeve. 6. Select the part number. Turn to the MiniSeal part number selection tables (Tables C and D, page 8-23 and 8-24) and find the table for the type of splice (stub or butt) required. Using the appropriate table, find the crimp barrel size range and the size and number of wires for your application. Then select the part number for the type of plating required. The color code accompanying that part number should match the color code you arrived at in Table B, confirming that the part number you have selected is correct. 8-22 Catalog 1654025 Revised 12-04 www.tycoelectronics.com Dimensions are in millimeters and inches unless otherwise specified.
