UL耦合器有拉力标准吗?
如题!电源线耦合器 4.3.2 Handles and manual controls
Handles, knobs, grips, levers and the like shall be reliably fixed so that they will not work loose
in normal use, if this might create a hazard. Sealing compounds and the like, other than
self-hardening resins, shall not be used to prevent loosening.
If handles, knobs and the like are used to indicate the position of switches or similar
components, it shall not be possible to fix them in a wrong position if this might create a hazard.
Compliance is checked by inspection, by manual test and by trying to remove the handle, knob,
grip or lever by applying for 1 min an axial force as follows.
If the shape of these parts is such that an axial pull is unlikely to be applied in normal use, the
force is:
– 15 N for the operating means of electrical components; and
– 20 N in other cases.
If the shape is such that an axial pull is likely to be applied, the force is:
– 30 N for the operating means of electrical components; and
– 50 N in other cases. 不知道樓主是否詢問此標準??若不是請包涵... 謝謝分享喔
