The screw connection of printed circuit board terminal block has always occupied an important position in the electronic industry, and now it has become an important component of printed circuit board. Its structural design takes into account the advantages of convenient wiring and reliable screw connection. Printed circuit board terminal block with spring connection are divided into pull back spring connection and butterfly spring connection. The pull back spring terminal and screw terminal can replace each other, which greatly increases the flexibility. IDC non stripping quick connection terminal can realize the quick connection of insulated conductor without using any tools. Pull the release aid to push the wire into the knife edge and cut off the insulation skin to realize air tight connection. This wiring method can save wiring time up to 60%, and can be used for Ethernet wiring (category 5). No matter what kind of connection terminal, they have the following advantages: 1. Large connection capacity, can adapt to various wiring requirements. 2. The wire clamp body shell and the welding pin are mechanically decoupled, that is, because the wire clamping body shell is not connected with the welding pin, the torque when tightening the screw will not be transmitted to the solder joint. 3. The welding needle is four sided, and the end shrinks and thins. When inserting the welding hole, it can prevent random rotation. Melt the solder into the hole. The long-term welding reliability of copper pin is guaranteed. 5. Tinned solder pin, easy to weld. 6. With cooling channel. 7. The end of welding pin shrinks and becomes thin, which is easy to install. Users can not only select different parameters, such as needle position and needle pitch, but also choose different wiring direction. In practical applications, the layout of components (such as the position of PCB in the shell) often limits the printed circuit board terminals. There is no doubt that the printed circuit board terminals which can provide a variety of different wiring directions have important practical significance: horizontal, vertical, oblique, and front. The more choices you provide, the more helpful it will be for practical operation. Printed circuit board terminals can even provide multi-layer wiring (layer 1 to 4) terminal blocks (MKDS... To mk4ds...). The arrangement between layers is very compact, and the needle pitch is staggered by half a vertical direction. This kind of terminal fully meets the design requirements of compact layout and space saving. The screw connection terminal can be compatible with the spring connection terminal. The so-called compatibility means that the two can be interchanged without changing the layout of the printed circuit board. This greatly improves the adaptability of the product and reduces the cost to a great extent. Cold head with connection, pre installation and special shell color, etc. - special type of terminal can be provided according to user's requirements.
