The Function and Classification of PCB Terminal

 


Terminal: It is a relatively basic accessory used to realize electrical connection, and it is also a fixed part of the terminal or connection between connecting wires, electrical appliances and control boards.


PCB Terminal: Generally speaking, it is a kind of accessory product for PCB  to realize electrical connection, which is divided into the category of connector in industry.


In addition, the PCB terminal has some other names: because its shape is generally in a row shape, it is also known as wiring block, terminal block, wiring board and so on.


The function of PCB terminal is to ensure the electrical connection is firm, safe and beautiful, and to improve the convenience of electrical installation and maintenance. 



Generally speaking, PCB terminal can be divided into the following types:


1. PCB Plug-in Terminal


It consists of two parts plug-in connection, one part presses the wire tightly, and then plugs into the other part, this part is soldered to the PCB board, suitable for automatic electrical connection system.


2. PCB Direct Welding Terminal


Through the principle of lifting and lowering of the wire clamping body, the welding foot and the wire clamping body are divided into two parts. The shell is strong and reliable, and the stitch distance is accurate. It is suitable for the power supply industry, the controller field, and the access control system.


3. PCB Fence Type Terminal


It can realize safe, reliable and effective connection, especially in high current and high voltage environment.


4. PCB Spring Terminal


It is a new type of terminal with a spring-loaded device, which has been widely used in lighting, elevator lifting control, instrumentation, power supply, chemistry and automobile power, etc.

How to Read Circuit Diagrams for Beginners

图片
     👉 https://www.jrpanel.com/R This articles shows how to read circuit diagrams for beginners in electronics. Learn to read electrical and electronic circuit diagrams or schematics. A drawing of an electrical or electronic circuit is known as a circuit diagram, but can also be called a schematic diagram, or just schematic. Circuit or schematic diagrams consist of symbols representing physical components and lines representing wires or electrical conductors. In order to learn how to read a circuit diagram, it is necessary to learn what the schematic symbol of a component looks like. It is also necessary to understand how the components are connected together in the circuit. Battery and Light Bulb Circuit Probably the simplest circuit that can be drawn is one that you may have seen in a school science class: a battery connected to a light bulb as shown below. Simple Circuit Diagram for Beginners Circuit Symbols and Physical Components Each electronic or electrical compon...

In JRPanel, Manual Color Toning Is High-precision Craftsmanship

图片
  The production of membrane switches requires the participation of the printing process. A screen printing machine is required for printing. The quality of the product printing depends on the printing operation process and the details of the printing. Among them, manual toning is the most important step .  Only the precise control of the proportion of each color can produce the color that the customer needs.   Toning is a very knowledgeable craft. There are three main colors. These three colors can decorate the membrane switch perfectly. The three colors are red, yellow, and blue. Other colors can be obtained by mixing any two of these three colors. For example, yellow plus blue to green. When mixing colors with colors, pay attention to thoroughly mixing the inks, so that the inks are thoroughly mixed together to avoid color inconsistency, resulting in incoordination of the membrane switch panel. After the color is adjusted, it needs to be compared. The color and gl...
