Terminal wiring diagram should show the various wiring wire type, size, and color cross-sectional area requirements; when connected to an external circuit components, a large section of the wire into the round connector should be used, shall be subject to the other terminals This standard applies to drain connection terminals combination of devices (such as resistors, fuses, relays, contactors, transformers, rotary motors, etc.), and these devices identification mark, also applies to the identification of specific wire terminals. When necessary, these General gives detailed application of certain products and the necessary support recognition in the relevant standard. 3, insulation coordination requirements are mainly based on the materials used, the operating voltage and environmental pollution levels, to close select clearances and creepage distances, so that security staff and products work, but also the product does not occur in the over-voltage insulation damage . 4, tracking index requirements, products in use due to solid insulating material surface in the electric field and an electrolyte to form a conductive path, so that the insulating properties of the insulating material housing decline, affecting the safety of the product. If at the same voltage level insulation condition good professional quality terminals, tracking index is high, the product creepage distance can be reduced, if the product Please enter the power industry development in this regard full attention. Fixed bad insulator not only play the role of insulation, usually provide precise alignment and extending protection to the contact, and also has a mounting position, the locking function is fixed on the device. Fixed poor light affect access to reliable power outages caused serious it is the product disintegrated. Disintegration refers to abnormal separation between terminals at mating state, since the materials, design harness terminals offer, crafts and other causes of structure is not reliable due to the wiring harness plug and socket terminal manufacturers, pin and jack, would serious consequences control power transmission and signal control system interrupts. As the design is not reliable, error selection process quality poor, poor choice molding process, heat treatment, mold, assembly, welding and other assembly is not in place, and this will result in fixed bad. In addition, since the coating from the skin, corrosion, bumps, molded fins, cracked, contact processing rough, poor appearance deformation causes, due to positioning the locking with the size of the ultra-poor, poor processing quality consistency and total separation force is too Adverse exchange and other factors caused, but also common diseases. These types of failures are generally able to detect and eliminate the use of the inspection process.
