The terminal block is a common basic accessory product in the automation industry. It mainly completes the effective transmission of intermediate media such as signals and currents. The safety protection device and the light operation are the two core values of the terminal facing the connection market.

In the power automation connection system, the appearance of the terminal block facilitates daily operation and maintenance. Its simple structure and rich variety can provide thousands of solutions for industry partners. When the terminal in the connection is short-circuited due to burnout, the application advantage of the terminal is obvious. After the power is cut off, the burnt-out terminal can be immediately replaced with the new product of the same model, and the entire maintenance time is greatly shortened. As the terminal itself, it mainly includes the following connection technologies:

1, screw connection

The screw connection is a screw-type terminal connection. Lianjie Electric reminds you to pay attention to the maximum and minimum cross-section of the connecting wire and the maximum tightening torque allowed by the different size screws.

2, welding

The most common soldering is soldering. The most important thing for solder joints is the continuity of the metal between the solder and the surface to be soldered. Therefore, for the wiring terminal block CONTROLENINEERINGChina copyright, cold-pressed terminals, the important is solderability. The most common coatings for solder ring ends are tin alloys, silver and gold. Reed contact has common soldered, soldered and notched solder tabs: pinhole contacts have a drilled arc notch for common solder ends.

3, crimping

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 accepted 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. According to the cold-pressed terminal CONTROLENGINEERINGChina copyright, cold-press the end wire cross section, and correctly select the wire barrel of the contact pair. It should be noted that the crimp connection is a permanent connection and can only be used once.

4, wrap

Winding is to wrap the wire directly around the angular contact wrap. When wound, the wire is wound under tension, pressed and fixed at the corners 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%; the wire diameter is larger than When the 0.5mm is controlled, the elongation of the conductor material is not less than 20%. Wound tools include a gun and a stationary wrap.

5, piercing one after another

Puncture connection, also known as insulation displacement connection, is a novel end technology invented by the United States in the 1960s. It has the characteristics of high reliability, low cost and convenient use. It has been widely used in various printed circuit board terminals. Cold-pressed terminals CONTROLENENGINEERINGChina all rights reserved, cold-pressed end, ring terminal. It is suitable for the connection of ribbon cables. It is not necessary to strip the insulation layer of the cable when connecting, and the tip of the "U"-shaped contact spring of the terminal is pierced into the insulating layer, so that the conductor of the cable slides into the groove of the contact spring and is clamped to the control engineering network. Copyright, so that the electrical connection between the cable conductor and the terminal reed is tight. It requires only simple tools, but cables with specified wire gauges must be used.
