Matters to note when selecting various industrial connectors

Industrial grade connector is an indispensable key component for industrialization because it is widely used in aerospace industry, also known as aerospace socket and aerospace plug. Connectors are widely used in intelligent manufacturing systems, aerospace, high-speed trains, automatic control, urban rail, 5G communications and other industries due to their strong versatility, diverse specifications and models, and perfect processing technology. Connector classification According to the appearance design, it can be divided into circular connectors, small connectors and micro connectors. According to the main uses of industrial production, it can be divided into switching power supplies and connectors. How to choose the connector (selection specifications) Structural specifications of the connector: Size is very critical. The connection in the product has certain indoor space restrictions, especially on the single board, and cannot interfere with other components. According to the application of indoor space, the installation part should choose the appropriate installation method (installation before and after installation, installation and fixing methods include screws, collar, bolts or quick locking, etc.) and appearance design (straight, curved, T, round, square); Connector shielding characteristics: With the development trend of communication equipment, EMC is becoming more and more important. When choosing industrial connectors, they must have metal shells, and cables must have shielding layers. The shielding layers are connected to their metal shells to achieve the actual effect of shielding. You can also choose injection molding processing methods. The power plug is packaged with copper, and the cable shielding layer is welded with copper;

Connector anti-accidental contact plug design scheme: The anti-accidental contact plug has two aspects: on the one hand, the connector itself rotates 180 degrees, resulting in incorrect signal connection. At this time, attention must be paid to selecting the anti-accidental contact plug, or connecting according to the relative position of the adjustment connector to make the installation unique; On the other hand, in order to reduce the type of raw material, the same connector is selected for several signals. At this point, the A power plug is most likely plugged into the B power plug. At this time, it must be noted that if this happens, it will cause serious harm; Characteristic impedance of connectors: Some signals have characteristic impedance regulations, especially frequency transmission signals. The matching resistance regulations are more stringent. Mismatch in characteristic impedance will cause signal reflection surfaces and then damage signal transmission. Generally, signal transmission has no special requirements for the characteristic impedance of the connector; Stability of the connector: it is used to connect signals, so the connection part should be reliable (such as face contact is better than point contact, needle eye is better than leaf spring, etc.); Connector application environment: There are unique regulations for connectors in outdoor, indoor, high temperature, high humidity, corrosion resistance, mold, severe cold and other environments; Practicality of connectors: Throughout the whole selection process, especially between the same product series, the selection of connectors has strong practicality, which can reduce the type of raw materials, control costs and reduce supply risks; Whether the connector has a locking function: In order to better avoid the problem of connector falling off during pairing, the connector is required to have a locking function to ensure good contact; Connector procurement cost: Cost cost is also a key factor in the whole process of model selection. With the increasingly fierce market demand, the cost of connectors and their production costs must be comprehensively considered; The pluggable frequency of the connector; Whether connectors can be used in extreme environments: Nowadays, there are many extreme environments, and there are many kinds of special connectors for extreme environments commonly used in connector design solutions, which can be selected according to specific situations, among which heat resistance, high temperature resistance, humidity resistance, corrosion resistance, salt resistance and other environments are finished product choices; Connector well-known brand: The key quality of the connector is reflected in the internal structure and design scheme of the commodity, especially the route, which is invisible to the human eye, so you must remember to look at the well-known brand and appearance when purchasing, it is best to stipulate the warranty period; The application of connector production technology is becoming more and more systematic, with a large number of technical elements, which will be more integrated into the sales market, carry out diversified and personalized product research and development, and incorporate a large number of environmental specification requirements.
