A brief analysis of the connection method of cold-pressed terminals


Cold-pressed terminal puncture connection method: cold- […]

Cold-pressed terminal puncture connection method: cold-pressed terminal puncture connection is also called insulation displacement connection. In practical applications, it has the advantages of high reliability, low cost, and convenient use. The piercing connection of the ferrule is suitable for the connection of ribbon cables. There is no need to strip the cable surface insulation for connection. The U-shaped contacts of the connector are inserted into the insulating layer.

The pierced connection of the ferrule causes the cable conductors to slide into the grooves that contact the springs and get caught, creating a tight electrical connection between the cable conductors and the connector springs. Just use simple tools and you're good to go, but the gauge of the cable must meet the requirements.

The riveting connection method of the cold-pressed terminal: the riveted connection of the cold-pressed terminal is a technique in which the metal is compressed and displaced within the specified limits to connect the wire and the contact pair. A good crimp can create a metal miscible flow that causes the wire to deform the contact material symmetrically. This connection is similar to a cold welded connection, which provides better mechanical strength and electrical continuity, and can withstand harsher environmental conditions.

The connection method used with cold-pressed terminals is generally considered to be better than proper crimp soldering, especially where high currents must be used. Special crimping pliers or automatic or semi-automatic crimping machines should be used for crimping. A suitable contact conduit should be selected according to the cross section of the conduit. Note that crimp connections are permanent, but can only be used once.

Connection method of cold-pressed terminal:
The cold-pressed terminal is directly inserted, which is a connection method directly connected to the board end. When using this type of cold-pressed terminal, generally use a longer terminal connection pin, insert it into the corresponding board end hole, and then dip tin solder.
