Introduce the connection method of cold-press terminal

1. The piercing connection method of the cold-pressed terminal:
The puncture connection method of cold-pressed terminals, also known as insulation displacement connection, has high reliability, low cost and convenient use in actual use. The piercing connection of this crimp terminal is suitable for the connection of flat cables. When connecting, there is no need to peel off the insulation layer on the surface of the cable, and the pointed end of the "u"-shaped contact lead of the connector is pierced into the insulation layer.
Through the piercing connection method of the cold press welding terminal, the conductor of the cable will also slide into the groove in contact with the wire and be clamped. At this time, a tight electrical connection is formed between the conductor of the cable and the wire of the connector. When it comes to such a connection method, it is enough to use a simple tool, but at this time the specified code must be selected.
2. Riveting connection method of cold pressing terminal:
The riveting connection of the cold-pressed terminal is a technology that compresses and displaces the metal within a specified limit, and then connects the wires into a contact pair. Generally, a good crimp connection can produce a mutual flow of metals, causing symmetrical deformation of the wire and contact material. This connection is similar to a cold welding connection, which can obtain relatively good mechanical strength and electrical continuity, and can withstand harsher environmental conditions.
The connection method used by cold-pressed terminals is currently considered to be better than welding by using correct crimping connections, especially crimping is necessary in the case of high current. When crimping, special crimping pliers or automatic or semi-automatic crimping machines are required for crimping. We should correctly select the wire barrel of the contact pair according to the cross section of the wire. Please note the long-term connection when crimping the connection, but it can only be used once.
3. Straight-line connection method of cold-pressed terminals:
The direct plug-in type of the cold-press soldering terminal is a connection method that directly connects the board end. When using this cold-press soldering terminal, in order to insert into the hole of the corresponding board end, the connecting leg of the terminal will become longer, and the method of soldering is generally used.
