What are the terminal block connections?

I. What are the terminal connection methods? Commonly used terminal connection methods are: welding, soldering, winding, puncture connection, screw connection, etc., as follows: 1, welding welding is the most common soldering, soldering connection is the most important is the solder material and the surface to be welded should be formed between the metal continuity. Therefore, for wiring terminals, the important thing is weldability. The most common plating on the soldered end of the wiring circle terminal is tin alloy, silver and gold. 2, welding crimping is for the metal within the specified limits of compression and displacement and will be connected to the conductor to the contact pair of a technology. It is now generally accepted that the use of a properly crimped connection is better than tin soldering, especially in high-current applications where crimping must be used. Crimping must be done with special crimping pliers or automatic/semi-automatic crimping machines. It should be noted that the crimp connection is a sexual connection, can only be used once. 3, winding connection is to wrap the wire directly around the angular contact with the contact parts of the winding column. When winding, the wire is wound under controlled tension, pressed and fixed in the prongs of the contact winding column to form an airtight contact. Winding wire has several requirements: the nominal value of the wire diameter should be in the range of 0.25mm ~ 1.0mm; wire diameter is not greater than 0.5mm, the extension of the conductor material is not less than 15%; wire diameter is greater than 0.5mm, the extension of the conductor material is not less than 20%. Winding tools include winding gun and fixed winding machine. 4, puncture connection puncture connection, also known as insulation displacement connection, was invented by the United States in the 1960s, a novel end technology, with high reliability, low cost, easy to use and so on. It applies to the connection of the ribbon cable, connection does not require stripping the cable insulation, relying on the terminal "U" contact reed piercing insulation, so that the cable conductor slides into contact with the reed groove and is clamped, so that the cable conductor and the terminal reed to form a tight electrical connectivity between. It only requires simple tools, but must use the specified wire gauge cable. 5, screw connection screw connection is the use of screw-type terminal connection, Ziheng Electric reminds you to pay attention to allow the connection of the conductor and the minimum cross-section of the larger and different specifications of the screws allow a greater tightening torque.
