4.3 管½(Tube)
管½本½无破裂、缺损等现象。
The tube shall have no defects such as crack, injury and contamination.
4.4 铜½(Brass
caps)
铜½应焊接牢固,以保证在未损坏熔断½时,铜½不½被卸脱。铜½表面镀
层应结实,端½两端均可承受大小至少为 5N、保持 1min 的½向拉力。
The cap should be firmly attached so that it is not possible to remove them
without damaging the fuse itself. The plated material should be firm. Each of the
cap should be bear an axial pull of 5N for 1min.
4.5 焊点(Soldering
joint)
焊接铜½端时,残留的助焊剂及焊锡等异物不应超出铜½口和沾附在保险管
外表面。
Soldering joint in end cap shall not melt during normal operation and shall not
have solder clips on the tube, element in view and outer surface of caps.
4.6 引脚(Lead)
保险管引脚应铆接牢固,½如下测试时,保险管引脚不应有松动或损坏:
The fuse-links lead should be firmly attached, At the conclusion of testing, the
fuse-links lead shall remain firmly attached:
1) 拉力测试:固定保险管本½,对引脚½加 10N 的½向拉力 1min。
Tensile: the force applied shall be 10N
2) 推力测试:固定保险管本½,对引脚½加 2N 的½向推力 1min。
Thrust: the force applied shall be 2N
3) 弯折测试:距离铜½约 2mm 的地方将引脚弯折 90°一次,并且½加 5N
的拉力。
Bending: the force applied shall be 5N and the number of bends shall be one。

5.机械特性(
Mechanical characteristics
)
保险丝应½承受下列试验:
Fuses should endure both of the following tests:
5.1 扭力试验:固定保险丝的一端铜½,然后在另一端铜½上顺时针和逆时针方
向上顺序½加 50g.cm 力矩,两端铜½不应松动,管½也不应破碎。
Wresting test:Fixed
one cap of the fuse,applied 50g.cm of
torsion power
in
clockwise and counter-clockwise on the other cap, as a result, the tube shall be no
damage and the cap should be no loosening.
5.2 拉力试验:固定保险丝的一端铜½,然后在另一端铜½上,沿水平½方向½
加 5N 的拉力 1min,两端铜½不应松动且管½不应破碎。
Pulling test:
Fixed one cap of the fuse,applied level pull force of 5N to the other
cap for 1 minute, there shall be no damage with the tube and no loosening with
the caps and the pigtails.
5.3 管子强度试验:保险管两端固定½后,在管½的中心½½½加 10N 的压力,
管½不应破碎。
Stress test:
Fixed two caps of the fuse,applied the stress of 10N to the tube
center , there shall be no damage with the tube .
