APPENDIX 5 – INSTRUCTIONS FOR THE USE OF CONNECTORS FITTED WITH JACKSCREWS

( , )

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 boardmount jackscrews should be fixed to the mounting board with

fixings and tightened to a torque of 21±2cmN.

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, 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.

NB: Care to be taken when aligning male and female threads to avoid cross-threading and

possible failure of parts.

3. On disengaging the two halves of the connector turn each of the floating jackscrews anti-

clockwise. Again ensure even loading by turning each screw in sequence for a maximum of

one turn until the jackscrew disengage. The connector can then be easily pulled apart.

4. Board mounting fixings must be fitted before Wave soldering.

5. Board mounting fixings can be fitted before or after reflow soldering, as preferred by

customer. If fitted before soldering, check that the fixings remain tight after soldering.
