DESCRIPTION OF CONNECTOR AND INTENDED APPLICATION. A range of 2mm pitch male and female rectangular, fully shrouded unsealed connectors with replaceable contacts for interconnecting board to board and board to wire. The range covers female connectors suitable for crimp or through board termination and male connectors available for straight or 90 through-board termination. The connectors are provided with a range of contact terminations (as shown in Appendix 1) which are gold or gold/tin plated. The contact zone of gold plated contacts is hard acid gold of 98% purity. The connector is intended for use as a connector in high packing density electronic equipment. Low and high frequency contacts can be supplied. The connector is polarised to prevent mis-matching and can be produced with a jackscrew feature as required. 2. MARKING OF THE CONNECTOR AND/OR PACKAGE (ORDER CODE).

Connectors are fitted with jackscrews where it is considered necessary to provide mechanical assistance in ensuring a satisfactory engagement and separation of the connector. This may apply in cases where engagement and separation forces are so high as to prevent satisfactory hand engagement, or where access to connector is restricted. Jackscrews also provide a locking feature, preventing the connector from disengaging under adverse conditions. In order to obtain maximum effectiveness from the jackscrew system, the following rules for their use should be observed. 1. The connector with the fixed jackscrew should be fixed to the mounting board by means of the male thread on the jackscrew, and an M2.5 nut. The nut should be tightened to a torque of 212cmN. 2. On engaging the two halves of the connector after ensuring correct polarity, lightly push home the floating half until the jackscrews touch. Then, maintaining the pressure, turn one of the floating jackscrews clockwise, by means of a 2mm A/F hexagon key, until it engages with the fixed screw. Repeat with the other screw. Then screw in each jackscrew, ensuring even loading by applying a maximum of one turn to each screw in sequence until the connector is bottomed. This will be evident by a sudden increase in the torque required on the screw. This torque should not exceed 23cmN. 3. On disengaging the two halves of the connector turn each of the floating jackscrews anti-clockwise by means of the 2mm A/F hexagon key. Again ensure even loading by turning each screw in sequence for a maximum of one turn until the jackscrew disengages. The connector can then be easily pulled apart. -6- C01708 COMPONENT SPECIFICATION (continued) APPENDIX 4 - GAUGES. NOTES: 1. Material = Steel to BS1407 or equivalent. 2.
