The connecting terminal of the printed circuit board with screw connection has been occupying an important position in the electronic industry, and has now become an important component of the printed circuit board. Its structural design gives more attention to the characteristics of the connection between the convenient and reliable screw connection.
Spring terminal blocks are divided into two types, which are a pull back spring connection and a butterfly spring connection. The back pull type spring connecting terminal and the screw terminal can replace each other, which greatly increases the flexibility.
IDC free wire fast terminal can realize fast connection of wires with insulating skin without using any tool in the situation. The bar will help push the blade and cut off the wire insulation, realize the tightness connection. This wiring way to save wiring time up to 60%, and through the certification can be used for Ethernet cabling (five lines).

No matter what kind of connection terminal, they have the following advantages:
1 wiring capacity, can meet all kinds of wiring requirements.
2. Clip line shell and the welding needle mechanical decoupling, is due to the wire clamping body shell and the welding pin is not connected into a whole, screw tightening torque is not transmitted to the solder joints.
3 welding needle four prism, end systolic thinning. When the welding hole is inserted, the random rotation can be prevented. The use of solder into the hole.
4 welding needle for copper alloy, welding needle without dirt to ensure the long-term reliability of the welding.
5 tin soldering pin, easy to weld.
6 with cooling channel.
7 the end of the welding pin shrink thin, easy to install.

Users can not only choose according to the needs of different parameters, such as needle, needle, etc., can also choose different wiring direction. In practical applications, the layout of components (such as the position of the PCB in the housing) often limits the wiring terminals of the printed wiring board. Can provide a variety of different wiring direction of the printed circuit board wiring terminal has important practical significance: horizontal, vertical, oblique angle, and the front. The more choices you have, the more you will have to help with the actual operation.
Printed wiring board terminals can even provide multi-layer wiring with (1 to 4 layers) wiring terminals (MKDS... To MK4DS...). Between layer and layer arrangement is very compact, and staggered half a stitch in the vertical direction. This kind of terminal is in full compliance with the layout of compact, space saving design needs.
Connection terminal of screw connection mode can be compatible with connecting terminal of spring connection mode. The so-called compatibility that both can be interchangeable and do not need to change the layout of the printed circuit board. This greatly improves the adaptability of the product, and to a large extent, reduce the cost.

With cold press head, pre installation and special case color, etc. - can be based on the requirements of the user to provide a special model of the terminal.
