Describes various bus terminals installation requirements bus terminals or bus and bus terminals and electrical appliances, when bolt lap joint, shall meet the following requirements: a, all kinds of drilling diameter lap bus connections and overlap length comply with the provisions of Appendix C of this specification, tighten with a torque wrench to tighten the bolt torque values ??of steel connections comply with Appendix D of this specification; b, busbar contact surfaces clean, grease-coated composite electricity, no glitches around the bolt holes; c, connecting bolts on both sides of a flat washer, gasket between adjacent terminals have more than 3mm of clearance back, nut side washers or spring-loaded locking nut; d, bolt by force, not to the electrical terminals subject to additional stress. Terminals are important systems engineering supporting elements are used to achieve electrical connection accessories, 1982, Phoenix Electric Company invented the world's first piece of modular terminal blocks, then laid the prototype of the modern terminals, but also the Phoenix The company applied for and obtained the first patent. Since then, Phoenix terminals in terms of maintaining innovative sensor terminals, which use a lot of products has become the industry standard. With the development of the electronics industry, the types of terminals are also more and more, can be divided into Continental Connection series, pluggable terminal block series, fencing series terminal blocks, spring-loaded speaker terminals series terminals, rail-mounted terminal blocks series, wall terminal block series and so on. Most of electronic connectors, terminals have terminals for 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, to make it easier to achieve contact metal to metal. Prevent corrosion: Most connectors made of copper alloy spring is usually in use in corrosive environments, such as oxidation, curing and other. 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.
