The terminal connection method refers to the connection method of the contact pair of the terminal and the wire or cable. Reasonable choice of termination method and proper use of termination technology are also an important aspect of using and selecting terminal blocks.

　　The most common soldering is soldering. The most important thing for soldering connection is the continuity of metal between the solder and the surface to be soldered. Therefore, solderability is important for terminal blocks. The most common plating on the solder side of the terminal is tin alloy, silver and gold. The reed type contact has the welding piece type, the punching welding piece type and the notched welding piece type for the common welding end: the pinhole contact has the drilling arc notch type for the common welding end.

　　 terminal connection wire crimping is a technique for compressing and displacing metal within specified limits and connecting wires to contact pairs. A good crimp connection can produce metal mutual fusion flow, so that the wire and the contact pair material symmetrically deform. This kind of connection is similar to the cold welding connection, which can obtain better mechanical strength and electrical continuity, and it can withstand more severe environmental conditions. At present, it is generally believed that using the correct crimp connection is better than soldering, especially in high current situations. Special crimping pliers or automatic or semi-automatic crimping machine must be used for crimping. According to the cross section of the wire of the cold-pressed terminal, the correct wire barrel should be selected correctly. It should be noted that the crimp connection is a permanent connection and can only be used once.

　　 winding is to wind the wire directly on the angular contact winding post. When winding, the wire is wound under controlled tension, pressed in and fixed at the corners of the contact piece winding post to form an air-tight contact. There are several requirements for winding wires: the nominal value of the wire diameter should be within the range of 0.25mm~1.0mm; when the wire diameter is not greater than 0.5mm, the elongation of the conductor material is not less than 15%; when the wire diameter is greater than 0.5mm, the conductor The elongation of the material is not less than 20%. Winding tools include winding guns and fixed winding machines.

Piercing connection, also known as insulation displacement connection, is a novel terminal technology invented by the United States in the 1960s. It has the characteristics of high reliability, low cost, and convenient use. It has been widely used in various printed board terminals. . It is suitable for the connection of ribbon cables. There is no need to peel off the insulation layer of the cable during connection. The tip of the "U"-shaped contact spring of the terminal is pierced into the insulation layer, so that the conductor of the cable slides into the groove of the contact spring and is clamped. A tight electrical connection is formed between the cable conductor and the terminal reed. It only requires simple tools, but cables with specified wire gauges must be selected. Screw connection
