Għaliex Il-Blokk Terminali Dawwar Iswed

L-użu mhux xieraq tal-blokka terminali jikkawża blackening jekk jinħaraq. Ilkoll nafu li l-blokki terminali huma t-tagħmir ewlieni għat-trażmissjoni tal-kurrent u l-enerġija, speċjalment kejbils u wajers, li huma aċċessorji użati b'mod komuni. Minħabba dan, jekk ikun hemm problema bil-qawwa u l-kurrent, bħal temperatura għolja, tikkawża li t-terminal jinħaraq, u mbagħad idur iswed u jitlef ir-rwol ta 'qawwa ta' trasmissjoni ta 'enerġija fit-tul-.

It-tiswed tat-terminali jista 'jkun ukoll minħabba ossidazzjoni kkawżata minn mess ħażin tal-gass. Terminali huma prodotti kondutturi. Jekk jintużaw, se jirreaġixxu ma 'gassijiet li m'għandhomx jintmess, u mbagħad jaffettwaw l-effetti ta' ossidazzjoni u blackening tagħhom. Din hija wkoll l-iktar kundizzjoni komuni ta’ blackening. Relattivament jitkellem, dan huwa fenomenu relattivament sikur, sakemm tagħti attenzjoni biex toqgħod 'il bogħod minn dawk il-gassijiet mhux mixtieqa u tevita l-ossidazzjoni, bħall-issiġillar tat-terminal.

The optimization of the appearance function of the terminal block can be done in two ways. One is the planning of the connector to establish and maintain a stable terminal touch interface. The second is to establish a metallic touch, which requires that any outer film layer does not exist or will break during the insertion process. There is no difference between the two ways of film and film breaking, that is, the difference between precious metal coating and non-precious metal coating. Noble metal plating, such as gold, palladium and their alloys, is lazy and has no coating. Therefore, for these appearance treatments, metal touch is "automatic". What we need to consider is how to keep the "noble" appearance of the terminal free from external factors such as pollution, substrate dispersion, and terminal corrosion.
