Nowadays, wiring terminal is a kind of accessory product used to realize electrical connection. It can also be said that it is produced for convenient connection. It is divided into the category of connector in industry. What are the precautions for the selection and use of wiring terminals? The following is a detailed introduction to HENGZHUO Neng.
What are the precautions for terminal selection
In addition to the brand and price of terminals, the selection of appropriate terminals should also include their use environment, space, wiring area and so on.
On terminal brand
To understand the production process of PCB terminal manufacturers, we should also determine the technical competitiveness, price positioning and other factors of the manufacturers. Only in this way can we determine which manufacturer is more worthy of their own selection and avoid being deceived by blind selection.
In the use environment
Environmental factors are one of the important reference factors. For example, terminals made of high temperature resistant materials should be selected in high temperature environment. Terminals with good moisture-proof performance are required in cold and humid environment, and terminals with acid-base resistant insulating materials are required in secondary acid-base environment.
On the installation space
The size of the installation space limits the selection of products under certain conditions, and only smaller terminals can be selected in a narrow space.
On the wiring area
The wiring area is also an important factor affecting the selection of terminals. For example, if the cable area is 2.5 square meters, should we actually select 2.5 square meters or larger terminals? In fact, in many cases, we need to select terminals with a wiring area greater than 2.5 square meters, because we need to use more than direct wiring in the actual use process, In addition, some accessories may be used to assist wiring, such as cold pressed terminal, SC terminal, etc., so the actual wiring area will be greater than that of the cable.
In addition, high voltage and high current may be generated at the moment of circuit disconnection, so this factor should also be taken into account in the selection of wiring terminals.
