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 component is represe

What Are the Factors That Affect the Cost of a Membrane Switch?

图片
  "How much does it cost to make a membrane switch? ”  It ’ s a common question we get from customers (and likely one you ’ re pondering if you ’ re reading this article). Unfortunately, the short answer is … it depends.   Since membrane switches are custom-made and include so many variables, it ’ s not feasible to provide a clear-cut estimate without first reviewing the specifications and discussing a few areas. However, based on our experience, three main factors impact the cost of manufacturing a membrane switch.   1.  Circuit design   The printed circuit is the most expensive layer of a membrane switch. Material choices and design (such as the number of traces) can significantly impact the unit ’ s cost. High-quality membrane switches typically use conductive silver ink, which provides the highest conductivity. Depending on application and budget requirements, lower-conductive inks such as carbon, copper, and alloys can be used.   2.   Number of layers and optional features

The Importance of Predictability for High-end PCB Manufacturing

图片
  If there is a way to ensure that the product is reliable, it is to ensure the predictability of its PCB, which is an important part of the product. In fact, PCB is the core component in almost all electronic products (from phones to computer systems) today. From automobiles to national defense, from aviation to technology, PCBs are ubiquitous in any industry. In all these industries, product reliability is of paramount importance. Whether it is medical technology or aviation technology, any mistake can cause huge losses. Similarly, in the medical field, equipment failure can have terrible consequences, leading to loss of life. This requires rewriting the traditional predictability method. Traditional predictability methods are usually based on  physical inspection .  However, physical inspection has inherent disadvantages, that is, only external defects can be inspected. Another problem faced by physical inspection is that when the PCB is complex and has countless vias, microsectioni
