What kind of connection technology does the terminal have? The terminal block is a common connection accessory product in the industrial automation industry. It has a wide range of types and complete functions. It has a good advantage in the field of wire connection and signal transmission. Termination mode refers to the connection mode of the terminal contact pair with the wire or cable. Reasonable choice of connection method and correct use of termination technology are also an important aspect of the use and selection of plastic terminals.

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 the correct crimp connection is better than the soldering, especially in the high current occasions, the crimp must be used. Special crimping pliers or automatic or semi-automatic crimping machine must be used for crimping. According to the wire section of the cold-pressed terminal and the cold-pressed end, the correct wire barrel should be selected. It should be noted that the crimp connection is a permanent connection and can only be used once.

Piercing connection has the characteristics of high reliability, low cost, and convenient use. It has been widely used in various printed board terminals, cold-pressed terminals, cold-pressed terminals, and ring terminals. It is suitable for ribbon cables. Connection. There is no need to strip the insulation layer of the cable during connection. The top 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.

Winding is to wind the wire directly on the angular contact winding post. During 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. Soldering is common soldering. For wiring terminals and cold-pressed terminals, solderability is important.
