Abstract

This drawing outlines the requirements for mounting hardware to be utilized by members of a family of compact high contact density (.025 inch) two piece nanominiature electrical connectors. These connectors are intended for printed circuit board, attached cable or fixed panel mounting/termination. This drawing details mounting screws, jackscrews, mounting brackets, retaining rings, and spacers which can be utilized to mount members of the nanominiature connector family. <br>Connectors specified in this specific requirements drawing must be capable of operating in the following environments: <br>a. Temperatures from &#8722;65&#176;C to +125&#176;C with temperature cycling. <br>b. Altitudes from sea level to 21,336 meters (70,000 ft) <br>c. Moisture conditions up to 100{}elative humidity. <br>d. Dust and fine sand atmosphere. <br>e. Salt laden atmosphere. <br>f. Vibration conditions to 20 g's. <br>g. Shock conditions up to 100 g's. <br>h. Free space vacuum environment <br>The complete part number shall be as specified on this item requirements drawing and constructed using the following format: <a><img alt="CHART" /></a> <br>Spacer PIN shall include 2 digits to identify the size as follows: </span><pre> -01 --- .109 (2.77 M) inch diameter, .015 (0.38 mm) thick spacer (see <a>figure 1</a>).</pre> <br> <br>Jackscrew PIN shall include 2 digits to identify the size as follows; <pre> -02 --- .060 (1.52 mm) inch diameter, .175 (4.45)/.169 (4.29 mm) inch length, see <a>figure 2</a>.</pre> <br> <br>Retaining ring PIN shall include 2 digits to identify the size, see <a>figure 3</a>. <br>Mounting screw PIN shall include 2 digits to identify the size, see <a>figure 4</a>. <br>Vertical mounting bracket PIN shall include 2 digits to identify the size and a letter designator to identify the material used, see <a>figure 5</a>, and <a>1.2.6</a>. <br>Vertical mounting bracket shell increase a single letter to identify the material. <a><img alt="CHART" /></a> <br><b><u>Intended Use:</u></b> Connector mounting hardware conforming to this drawing is intended for use when military specifications do not exist, and qualified military connector mounting hardware that will perform the required function is not available for original equipment manufacturers applications. This drawing is intended to prevent the proliferation of unnecessary duplicate specifications, drawings, and stock catalog listings. When a military specification exists and the product covered by this drawing has been qualified for listing on a qualified product list (QPL), this drawing will be inactivated and will not be used for new design. The QPL product will then become the preferred item for all applications. <br>
