Three conventional connection methods to ensure the connection safety of the terminal

1. The solder connection method of the terminal block:

In the solder connection method of the terminal, the main thing is the tin wire and the surface to be soldered. They should form a metal connection function. Therefore, 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. The riveting connection method of the terminal block:

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

This method is more suitable for cold welding connection, which can achieve outstanding mechanical strength and electrical continuity, and can be used in harsher environments. Now the more widely 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 block:

This kind of PCB terminal connection method can also be called insulated displacement connection. It is reliable and functionally high, and the cost is very low. The main thing is that it is very fast to use, and it 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.
