Usage Of Cold Pressure Terminal

Cold-pressed terminals, also known as insulated terminals, electronic connectors, and air connectors are all attributed to cold-pressed terminals. It is an accessory product for electrical connection and is industrially belongs to connectors.



The connection method of the cold-pressed terminals can be divided into six types, which are:

1. Solder (solder type)

The most important aspect of the solder joint is the continuity of the metal between the tin wire and the surface being welded. Therefore, it is important for the connector to be solderable. The most common coatings on the soldered ends of connectors are tin alloys, silver and gold.


2. IDC (piercing)

The piercing connection, also known as the insulation displacement connection, has the characteristics of high reliability, low cost and convenient use, and is suitable for the connection of the ribbon cable. The connection does not need to be stripped of the insulation layer of the cable, Relying the tip of the "U" shaped contact spring of the connector into the insulating layer, causing the conductor of the cable to slide into the groove of the contact spring and be clamped, This results in a tight electrical connection between the cable conductor and the connector spring. It requires only simple tools, but must choose the cable with specified wire gauge.

3. Crimping (rive pressing)

Crimp is a technique for compressing and displacing metal within specified limits and connecting the wires to the contact pairs. A good crimp connection creates a metal interflow flow that causes the wires and contacts to symmetrically deform the material. This connection is similar to a cold welded joint and provides better mechanical strength and electrical continuity, and it can withstand harsher environmental conditions.


It is generally believed that the correct crimp connection is better than soldering, especially in high current applications where crimping is required. Special crimping pliers or automatic and semi-automatic crimping machines are required for crimping. The wire barrel of the contact pair should be correctly selected according to the wire cross section. It should be noted that the crimp connection is a permanent connection and can only be used once.


4. SMT (Surface Mount Termination)

SMT (Surface Mount) is a method of fast connection of the board end Conn. The connection part of the board end is pre-filled with cream solder, and then Conn is accurately placed on the line of the board end by a special machine, and then connected after high temperature. Therefore, SMT's conn plastic and electric ferry must be able to withstand high temperatures.

5. DIP

DIP (in-line assembly), a connection method of the plate end Conn, the connecting leg of the CONN will be longer to be inserted into the hole of the corresponding plate, and then soldered by immersion tin.


6. Wrap (winding)

Winding is to wrap the wire directly around the contact part terminal with edges. When winding, the wire is wound under the control of tension, pressed and fixed at the terminal of the contact wrap to form a hermetic contact. There are several requirements for the winding wire: the nominal value of the wire diameter should be in the range of 0.25mm~1.0mm; when the wire diameter is not more than 0.5mm, the elongation of the conductor material is not less than 15%; when the wire diameter is larger than 0.5mm, the conductor The elongation of the material is not less than 20%. Wound tools include a gun and a stationary wrap.
