Detailed explanation of the advantages of three different connection methods of cold-pressed terminals
Cold-pressed terminals can also be called insulated terminals, or electronic connectors. They are mainly an accessory product for electrical connection. They are mainly connectors in the industry. However, due to the The degree of automation is getting higher and higher, so the industry has higher requirements on related control. Then the demand for cold-pressed terminals is also increasing day by day. Because the electronics industry is developing rapidly, the scope of use of cold-pressed terminals will be more extensive, and there will be more and more types. At present, in the industry, the use of The most widespread and common should be the terminal products of the pcb board, followed by the continuous terminals of the hardware and the spring list, etc. The main connection methods of cold-pressed terminals are: 1. Solder-type connection of cold-pressed terminals: In the solder connection of cold-pressed terminals, the main thing is the tin wire and the surface to be welded, and a metal should be formed between them. The continuous performance of the connector, so for the connector, the main thing is the solderability, and on the soldered end of the connector, the more common plating layers are silver, alloy and gold. Second, the piercing connection method of the cold-pressed terminal: This connection method of the cold-pressed terminal can also be called the displacement connection of the insulation, which is relatively reliable in performance and very low in cost. The main thing is to use it. It is very convenient and suitable for connecting ribbon cables. When connecting, there is no need to peel off the insulation layer in the cable, and the tip of the spring sheet can be directly pierced. 3. Riveting connection method of cold-pressed terminal: The main purpose of crimping is to ensure that the cold-pressed terminal can be compressed within the specified limit, or the wire can be directly connected by displacement. If it is a relatively high-quality crimping, it can be It ensures that the metal will not dissolve in the flow phenomenon, and it can also ensure that the material will not deform between the wire and the contact. This method is more suitable for cold welding connection, which can have good mechanical strength and electrical continuity, and can be used in harsh environments. It is used when the current is relatively large, and professional tools must be used when crimping.
