How to choose Connecting Terminals?
The Copper Insulated Connecting Terminal is the part where the battery is connected to the external conductor.In electrical engineering,Cable Lug Connecting Terminals refer to terminal Terminals,also known as terminal blocks.The types are divided into single holes,double holes,sockets,hooks, etc.,and the materials are divided into silver-plated copper,galvanized copper,copper,aluminum,iron,etc.Their function is mainly to transmit electrical signals or to conduct electricity.
When facing the selection of terminal blocks,the first thing that everyone thinks of is the wire diameter, current,wiring direction,application occasion,wiring method, etc.The wire diameter and current are the wire diameter and rated current.In addition,the wiring direction generally has positive and negative.The design of the side outlet is mainly to facilitate the operation of technicians,thereby improving the efficiency of work.Professional Production Connecting Terminals have a wide range of applications.For example,the purchased terminals are for soldering on the PCB circuit board,so it is impossible for you to choose the terminal wiring method used on the rail. Generally,there are common wiring methods such as docking, suspension,and fixing.The basic composition of the terminal is composed of an insulating base,an insulating partition,and a wire piece,and the insulating base is integrated. 
Under different environmental conditions,there are certain rules for the correct selection and use of terminal blocks.Although there is no clear rule of use in the industry,specific Cable Lug Connecting Terminals can be selected according to the specific use environment and conditions.There are four basic principles that can be used as a reference. 
First of all, before setting the terminal, you need to know what kind of terminal you want. According to the function of the terminal, there are ordinary terminals, insurance terminals, test terminals, grounding terminals, double-layer terminals, double-layer conduction terminals, three-layer terminals, and three-layer terminals. Layer conduction terminal, one-input double-outlet terminal, one-input three-outlet terminal, double-input double-outlet terminal, knife switch terminal, overvoltage protection terminal, marking terminal, etc. According to the current classification, it is divided into ordinary terminals (small current terminals) and high current terminals (above 100A or above 25MM wires). Classified by appearance. It can be divided into rail-type terminals, fixed-type terminals, circuit board terminals (PCB terminals), etc. 
The second thing to consider is the size of the wiring. For different wiring terminals, its size and wiring range are different. Usually, when using terminals, it is better to choose a slightly larger wiring range than the actual wire diameter. Because the current market standards are confusing, if you choose a wiring hole that is the same size as the wire diameter, you may not be able to insert the wire into the crimping frame because the terminal produced in the market does not meet the standard and the wiring range becomes smaller.
The third is the current.For the rail terminal,which has been in the market for decades,there are regulations on the current in the industry. Different models have specific current specifications.The product must meet this standard or exceed this standard. The last is the size of the space used.Different terminals can be selected for different space sizes.For example,in a small space,you can choose a double-layer terminal block or a three-layer terminal block.
