Plugs shall betested for pin movement by clamping the pin or pins not under test in a rigid holding block positioned 5 ±0.5 mm from the plug face and applying a forceof 18 ±1 N to the pin under test.The design of the block shall be such that the pin under test shall not comeinto contact with the block during the test.& X4 Y- |) p9 U1 b
Except fornon-rewireable plugs, the test shall be carried out without a cord attached tothe plug, and with the terminal screws loosened sufficiently to allow a 1 mm2 conductor to be connected.

For all plugs,the point of application of the force shall be 14 ±0.5 mm from the face of the plug along the pins, and thedirection of the force shall be--

Over a period of10 s, the force shall be gradually applied to each of the pins in the manner prescribed in Items (a) and (b), maintained atits maximum value for 10 s, and then released. The deflection of the pins shallbe measured along the line of force relative to the face of the rigid holdingblock during the period when the force is applied. The maximum deflection shallnot exceed 2.0 mm.

答:5 D2 J- h6 \- B
看点主要是夹具。
2 r" D1 m3 w6 G3 B0 r不做测试的插销用一开槽并有螺钉的夹具固定。此夹具很小,大约30mm长,直径约8mm。1 b6 s3 y& V# a5 r- y" O. G8 Z
做测试的插销的夹具用一开槽并有螺钉的夹具固定,只不过是多了一个吊环,用于吊砝码。要特别注意,此测试整个过程是在环境温度40度的条件下进行,包括preconditon的1小时。( S- g' H7 C% o+ }5 `0 [4 L
