1. The solder connection method of the terminal:

     In the solder connection method of the terminal, the main thing is the tin wire and the surface to be soldered, and the continuity of the metal should be formed between them. So for the terminal, the main thing is the solderability, the soldering end of the single The more common coatings are silver, alloy and gold.

2. Riveting connection method of terminal block:

    The main purpose of crimping is to ensure that the terminal can be compressed within the specified limits, or the displacement to connect the wires directly. If it is a relatively high-quality crimping, it can ensure that the metal will not flow in mutual dissolution, and it can also Ensure that the material will not be deformed between the wire and the contact.

    This method is more suitable for cold welding connection, can achieve good mechanical strength and electrical continuity, and can be used in harsher environments. At present, the more commonly used connection method should be crimping, especially suitable for It is used when the current is relatively large, and professional tools must be used when crimping.

3. Piercing connection method of terminal:

    This kind of connection method of PCB terminal block can also be called insulated displacement connection. It is reliable and has high performance and very low cost. The main thing is that it is very convenient to use and is more suitable for connecting ribbon cables. , And when connecting, there is no need to peel off the insulating layer in the cable, just use the pointed end of the bullet to pierce it.

     The above are the three most common connection methods currently. Due to industrial innovation, more and more customized terminal products have been developed, and they are no longer limited to the above methods.
