    The wiring terminal row is a common basic accessory product in the automation industry. It mainly completes the effective transmission work of intermediate media, such as signal and current. The safety protection device and portable operation are the two core values of terminals to connect to the market.

    In the power automation connection system, the wiring terminals are convenient for daily operation and maintenance. They are simple in structure and rich in variety, and can provide thousands of solutions for the industry partners. When the terminals in the connection are short circuited due to burnout, the application advantages of terminals are obvious. After being powered off, they can immediately remove the burned terminals and replace the new products of the same type, so the whole maintenance time is greatly shortened. As the terminal itself, it mainly includes the following aspects of the connection technology:

    1, screw connection

    The screw connection is made by screw connection terminal. The Jie Jie electric reminds you to pay attention to the maximum and minimum cross section of the connection wire and the maximum tightening torque allowed by different specifications of screws.

    2. Welding

    Welding is the most common soldering. Soldering solder connection is most important is the surface material and are welded to be formed between the metal continuity. Therefore, the wiring terminal CONTROL ENGINEERING China copyright all, cold terminal, the important is the weldability. Tin alloy, silver and gold are the most common coatings at the welding end of the terminal ring terminal. The common welding ends include the weld sheet, the eye flushing and the notched flick, and the hole type contact has a hole in the common welding end.

    3, press joint

    Compression is a technique to compress and displace metal within a specified limit and to connect the wire to the contact pair. A good joint can produce metal intermelting flow, which makes the wire and contact symmetrical to the material. This connection is similar to cold welding connection, can get better mechanical strength and electrical continuity, it can withstand more severe environmental conditions. It is generally believed that the proper pressure connection than soldering is good, especially in the high current situations must use crimp. Special pressing clamp or automatic and semi-automatic press must be used when pressing. According to the cold press terminal CONTROL ENGINEERING China all rights, cold pressure end lead cross section, the correct selection of contact pair of traverse. It is important to note that the connection is a permanent connection and can only be used once.

    4.The winding is winding the wire directly on the contact column with the angle of contact. When the wire is wound, the wire is twisted under the control of the tension and is pressed into and fixed at the angle of the contact column to form the air tightness contact. There are several requirements: around the wire diameter of wire nominal value should be in the range of 0.25mm~1.0mm; the wire diameter of not more than 0.5mm control works copyright, extending conductor material rate not less than 15%; control engineering copyright wire diameter is greater than 0.5mm, extending conductor material ratio of not less than 20%. The winding tools include the gun and the fixed winder.

    5.Pierce also called insulation displacement connection connection, by the United States in 60s invented a novel end technology, has the advantages of high reliability, low cost, easy to use, has been widely used in various printed circuit board wiring terminal, cold terminal CONTROL ENGINEERING China copyright, cold end, ring terminal. It is suitable for the connection of the ribbon cable. The insulation layer connection does not need to strip the cable, depending on the terminal "U" shaped contact spring tip piercing the insulation layer, the cable conductor slide contact spring is clamped in the groove and control engineering copyright, so as to form electrical connection between the conductor and terminal reed. It only needs simple tool, but must use the provisions of wire cable.

It is widely considered to use correct joint connection at present
