In the structure of the plastic junction box, the box body and cover are usually fixed with four M4 stainless steel screws. The four corners of the box body may be inlaid with threaded copper pillars. There are bosses inside for mounting circuit boards or DIN rail components. The cover is available in transparent and opaque forms.
Its technical parameters include protection level IP65, impact resistance up to IK07 or IK08, flame retardant PC material up to UL94-5VA or UL94-V2, ABS material UL94-HB, working temperature range ABS -20℃～60℃, PC -40℃～120℃ [3], complete insulation, environmental protection standard RoHS compliant and halogen-free.
Mainly used for wall socket installation. Model 10-23 has an outer diameter of 160x45x55mm, protection level IP65, impact resistance IK07, temperature range short-term -40℃~80℃/long-term -20℃~60℃.
Common raw materials include ABS resin and PC (polycarbonate). ABS resin has excellent impact resistance, heat resistance, chemical resistance, and electrical properties. PC material, on the other hand, has high impact strength, good dimensional stability, is colorless and transparent, and has good electrical insulation and corrosion resistance.
