2.13.9.2 Fixing of pins
- m5 J+ e* P U9 UA separate sample of a plug shall be heated to a temperature of 50 ±2°C for 1 h and maintained at that temperature during the whole of these tests, including the 5 min period after removal of the test load.! x+ Y# E4 c1 B
The plug shall be held firmly in such a manner that there will be no undue squeezing or distortion of the body, and the means of holding shall not assist in maintaining the pins in their original position.
: T9 ?8 D" ^0 A- O7 BEach pin, in turn, shall have applied to it a force which, over a period of 10 s, shall be increased steadily to 60 ±0.6 N and held at this value for 10 min.
1 C0 x% A1 D1 V% T" {1 ^4 Z, D. f% DTwo tests on each pin shall be conducted, one with the direction of force along the length of the pin towards the body of the plug, and the other with the direction of force along the length of the pin away from the body.
% P4 g2 ?8 c rThe attachment of pins shall be considered inadequate if any pin is displaced relative to the adjacent material of the body by more than 2.4 mm at any time during these tests, or if any pin fails to return to within 0.8 mm of its nominal length specified in Figure 2.1 within 5 min of the removal of the test force.

不过,我想可能是个施加压力和拉力的设备,可以调节压力和拉力。
2 [9 k7 H; f# |. X+ V, H先不施加力,将插头升温到50度并保持1个小时。再对插头的每个受测试插销施加60N的压力或拉力,测试10min。每次只对一个插销加压力或拉力。
1 k, g0 c9 _+ p: l& Y这段解释只是我个人理解,没有见到实物设备。如果有同行有信息请交流。 |
