1. Draw the wiring diagram wiring terminals shall conform to GB6988.6-1993 table "Control system function to draw the map of the" requirement; 2, all the terminals and leads should be marked with an electrical schematic consistent with the text symbols and wiring number. Schematic of the project code, terminal numbers were compiled and wire numbers should be consistent with GB5094-1985 "Electrical Technology in the project code-named" General GB4026-1992 "electrical equipment terminals and wire line side specific identification and application of an alphanumeric system "and GB4884-1985" insulated wire markers "and other regulations; 3, with different electrical schematics, wiring diagrams at the terminals of each part of the same terminals (contacts, coils, etc.) must be drawn together; 4, Terminal Blocks map will be drawn with fine lines. Traces the way points after the alignment of the front plate and the board traces two general use before the board traces terminal agent, for simple electrical control unit, a small number of terminals, without complicated wiring relationship can be directly connected to draw between elements line; for complex parts, terminal numbers and more, wiring more complex cases, is generally used to go trough, as long as the numbers marked on each wiring terminals, do not draw a connection between the various components; 5, terminal block wiring diagram wiring should be marked with a variety of wire types, specifications, cross-sectional area and color requirements; 6, when connected to an external circuit components, a large section of the wire into the round connector should be used, the other should be connected via terminal blocks . Most wholesale electronic connector terminals, terminals have surface treatment, generally refers to plating. There are two main reasons to protect the substrate from corrosion terminals reed; the second is to optimize the performance of the terminal surface, to establish and maintain contact with the interface between the terminals, especially the film Control. In other words the terminal, to make it easier to achieve contact metal to metal. Prevent corrosion: most connectors reed is made of a copper alloy terminal prices, typically used in corrosive environments, such as an oxide, sulfide and the like. Terminal plating is to make the reed isolated from the environment, to prevent corrosion. Electroplating materials, of course, if not corrode, and at least in the application environment. _ Chong Xu Song terminals offer electronic products plant (certified) _ nave terminal by Dongguan Shijie Xu Song Chong electronic products factory provided.
