中文版Nowadays, with the higher and higher degree of industrial automation and the stricter requirements of industrial control, the consumption and demand of wiring terminals are also gradually rising! However, in the actual development process, there are still some problems in the terminal manufacturers, as follows:
1. advantages of technology substitution
In addition to some large terminal manufacturers, the smaller terminal manufacturers have relatively simple goods. In order to obtain customers, they lower the price, which leads to the deterioration of market competition and the weakening of the interests of large terminal manufacturers.
2. market chaos
Driven by the interests, some small terminal agency manufacturers combine the authenticity of the terminal products, which deceives the terminal demand customers and reduces the brand image of the agency enterprises.
3. Product quality varies
The quality of wiring terminal products in the market is uneven. In order to make profits, some businesses violate the integrity and sell many products to customers without passing the quality inspection, which seriously affects the brand image and reputation.
What are the requirements for terminal selection?
At present, there are more and more terminals on the market, and different terminals have different performances. What requirements should be paid attention to when purchasing terminals?
1. the space size limits the product selection under certain conditions
In a narrow space, only terminals with smaller size can be selected. If the fixing method is rail type, but the height of the terminal plus the rail exceeds the wiring space, only terminals fixed by other methods can be selected. If the height is enough to connect multiple cables, double-layer or multi-layer terminals are required.
2. the voltage and current determine the use scenario
Generally, there is no problem with voltage and current, but high voltage and high current will be generated at the moment when the circuit is disconnected. Therefore, the voltage and current required in this case is much higher than that in the normal working environment. These factors should also be taken into account in the actual selection.
3. environmental factors are one of the most important reference factors
For example, terminals made of high-temperature resistant materials should be selected under high temperature environment, terminals with very good sealing and moisture-proof performance should be selected under heavy moisture environment, and materials with acid-base resistance should be selected under acid-base environment. Therefore, no matter what kind of market the terminal block is in, these factors should be taken into account to ensure that it can meet our use needs.
