Key points for choosing various industrial connectors
Connectors are widely used in industries such as intelligent manufacturing systems, aerospace, high-speed rail, automatic control, urban rail transit, and 5G communication due to their strong universality, diverse specifications, and advanced processing technology. Among them, industrial connectors are essential key components in industrialization. Here are some key points to consider when selecting industrial connectors
1.Structural specifications of industrial connectors
The size of industrial connectors is critical, as there are internal space limitations for connections within equipment, especially on a single board where interference with other components is not allowed. Therefore, suitable installation methods (including screw, snap ring, bolt, or quick lock) and appearance designs (straight, curved, T-shaped, circular, square) should be chosen based on the internal space application.
2.Shielding properties of industrial connectors
Along with the development of communication equipment, EMC (electromagnetic compatibility) is becoming more important. Therefore, industrial connectors must have a metal shell, and cables must have shielding layers. Through the connection between the metal shell and the shielding layers, actual shielding effect can be achieved. Injection molding processing method can also be used, with the power plug packaged with copper, and the cable shielding layer welded to copper.
3. Anti-miscontact plug design scheme of industrial connector
There are two aspects of anti-miscontact plug of industrial connector.
On one hand, the industrial connector itself may rotate 180 degrees, resulting in incorrect signal connections. Therefore, plugs with anti-misconnection features must be chose, or the relative positions of the connectors need to be adjusted, so as to make the installation unique.
On the other hand, to reduce the types of raw materials, the same connector may be used for several signals. In this case, the A power plug may be plugged into the B power plug, resulting in serious hazards.
4.Impedance characteristics of industrial connectors
Some signals have characteristic impedance specifications, especially the frequency transmission signals, which have strict requirements for matching resistance. Characteristic impedance mismatch can lead to signal reflection and signal transmission damage. There are generally no special requirements for connector characteristic impedance in signal transmission.
5.Stability of industrial connectors
Connectors are used to connect signals, so the connection should be stable and reliable. For example, face contact is better than point contact, and pinhole contact is better than leaf spring contact.
6.Application environment of industrial connectors
There are unique regulations for connectors used in outdoor, indoor, high-temperature, high-humidity, corrosion, mold, extremely cold and other environments.
7.Practicality of industrial connectors
Throughout the selection process, especially within the same product series, it is advisable to choose products with strong universality to reduce raw material types, control costs, and lower supply risks.
8. Locking functions of industrial connectors
To better avoid connector detachment during pairing, the industrial connectors should have locking functions to ensure good contact.
9.Purchasing costs of industrial connectors
Cost is also a key factor in the selection process. With the increasingly fierce market demand, the material cost and production cost of connectors must be considered comprehensively.
The production process of industrial connectors is becoming increasingly systematic, with a large number of technical elements. It will be more integrated into the sales market, conducting diversified and personalized product research and development, and incorporating a large number of environmental regulatory requirements.
