How to handle bridge fittings, how to wire
Bridge fittings Raw zinc alloy, galvanized or chrome-plated. One end is internally threaded, one end is externally threaded, the internal thread is connected to a steel pipe with external threads, external thread Connection bridge, distribution box, junction box and other terminal equipment;
The bridge pipe joint raw material zinc alloy, galvanized or chrome-plated, one section is a circlip, one end is external thread, the circlip is used to connect the unthreaded steel pipe ( Water gas pipe, electric wire pipe), external thread is used to connect the bridge, distribution box, junction box and other terminal equipment;
The bridge pipe joint raw material zinc alloy, galvanized or chrome-plated, one section is three-column top wire, one end is External thread, three-column top wire is used to connect unthreaded steel pipe (water gas pipe, electric wire pipe), external thread is used to connect bridge, distribution box, junction box and other terminal equipment;
Zinc alloy, galvanized or chrome-plated, this series of design is relatively new, the joint head circlip is used to connect the unthreaded steel pipe (water gas pipe, wire pipe), the middle part is full thread, with a threaded movable locking piece, The end end is an inactive retaining wall surface integrated with the thread. When using, the threaded wall surface is firstly passed through the bridge opening from the inside, the wall surface is inside the bridge frame, the thread extends out of the bridge opening, and then the locking piece is screwed. The main body of the thread retaining wall is completely fixed, and then the hex nut with the circlip is screwed, and the steel pipe is inserted into the circlip to tighten the steel pipe and the bridge. The bridge pipe joint product is widely used. It is connected to various types of machinery and equipment, electricity, construction, security and so on. How to deal with the bridge pipe joints How to wire the wires The types of wires to be connected and the connection forms are different, and the connection methods are also different. Commonly used connection methods are twisted joint, tight joint, welding and so on. Care should be taken to remove the insulation of the wire joints before joining, taking care not to damage the core. Twisting is the direct twisting of the core wires that need to be connected to the wires. Copper wires are often twisted and joined. (1) Direct bonding of a single-strand copper wire. The small-section single-strand copper wire connection method is shown in Figure 1. First, the core wire ends of the two wires are X-shaped, and then they are wound around each other for 2 to 3 turns, then the two wire ends are straightened, and then each wire head is placed in another After the core wire is tightly wrapped around 5 to 6 turns, the remaining wire ends can be cut.
