On install the shell fragment of a similar Chinese enkianthus additional, thickness, at 0.3～0.35 millimeter, is sleeved on binding post,
With the elastic electrical contact realized with ammeter stomidium of Chinese enkianthus.Such method can cause two kinds of differences
Between the metal of material, (pyrite binding post and beryllium-bronze etc.) produces when the electric current having 1A～100A flows through
Voltage drop, simultaneously by what such environmental effects, if things go on like this shell fragment oxide etch can increase contact resistance,
Ultimately resulting in ammeter string holes internal heat generation, device and ammeter are burnt in loose contact.Actual field uses
The binding post feedback information of Chinese enkianthus shell fragment also confirms this point.
2, the wiring in installing ammeter box, the stranded conductor peeling insulated hull off is inserted every by existing mode
Then screw-driving in individual epi-position terminals sub-aperture, the most mostly can weigh wounded individual conductors and break and shadow
Pilot's electrical property, it is also possible to artificial crimping is not tight, and these hidden danger can involve damage table case.
3, stranded conductor inserts epi-position wiring hole, the root of its copper core and insulated hull can exposed outside,
Easily carried out short electricity-filching by lawless people.
The Chinese utility model patent of Application No. CN201420528955.4, discloses a kind of ammeter
Case connector, the rear end of connector is fixed with pluggable terminals, described pluggable terminals be plugged in described in patch
