Piercing connection method of cold-pressed terminal

The piercing connection of the cold-pressed terminal is also known as the insulation displacement connection.

In practice, the reliability is very high, the cost is relatively low, and it is also very convenient to use. The piercing connection of the cold-pressed terminal is suitable for the connection of ribbon-type cable.

When connecting, there is no need to peel off the insulation layer on the surface of the cable, relying on the tip of the “U” shape connector spring to contact by piercing into the insulation layer.

The piercing connection of the cold-pressed terminal causes the conductor of the cable to slide into the slot contacting the spring and be clamped, so that a close electrical connection is formed between the cable conductor and the spring of the connector.

Only simple tools are needed, but cables with specified wire gauges must be selected.

Crimping connection method of cold-pressed terminal

The crimping connection of cold-pressed terminals is a technique in which the metal is compressed and displaced within a specified limit, and then the wire is connected to the contact pair.

Generally, a good crimping connection can produce metal miscible flow, so that the conductor and the contact material are symmetrically deformed.

This kind of connection is similar to cold welding connection, which can obtain better mechanical strength and electrical continuity, and it can withstand worse environmental conditions.

For the connection mode adopted by the cold-pressed terminal, it is generally believed that the correct crimping connection is better than tin welding, especially in the case of large current.

Crimping requires the use of special crimping pliers or automatic, semi-automatic crimping machine.

We should correctly select the contact pair of wire conduit according to the cross section of the wire.

It should be noted that the crimping connection is permanent, and it can only be used once.

Plug-in connection method for cold-pressed terminals

The direct plug-in type adopted by the cold-pressed terminal is a kind of connection mode which is directly connected to the board. When using this kind of cold-pressed terminal, the connecting pin of the terminal is generally longer so that it can be inserted into the hole of the corresponding board. Then soldering by dipping tin.
