First, the origin of industrial connectors

The first appearance of industrial connectors was during the Second World War, which was originally produced to meet the rapid maintenance or replacement of equipment components in the second World War, in order to reduce the stay time of the fighter on the ground during maintenance as much as possible; To this end, designers will first the main components of the unit and modular, and then through the connector will be effectively and quickly connected to each other together, this innovative method, after practice proved that it can greatly shorten the maintenance time, but also improve the reliability of the connection between the components of the module, thus, the connector in the military industry has laid its indispensable important position.

Second, industrial connectors are widely used

With the rapid development of electronics, medical, computer communication and other industries, more and more industries are in urgent need of finding a fast, convenient, effective and reliable connection tool, and then the industrial connector has become everyone's best choice.  Industrial connectors are also the rapid rise of these industries with the rapid development of these industries, and now we can see it in many industrial environments.  Industrial connectors can make the entire installation and replacement process faster and easier, but also put forward more stringent requirements for connector capabilities.  In contrast, the connector applied in the industrial environment needs to be more resistant, stronger and tougher, so the industrial connector can not only be used in the manufacturing industry, but also can be widely used in industries with poor working environment such as mineral energy.  With its excellent shockproof, dustproof and waterproof ability, it can always maintain the stability of the contact interface impedance, so as to maintain the safe and effective connection and complete the transmission of signals or currents.

Third, the general industrial connector should have the performance

1. High and low temperature resistance: the working temperature of the connector is -20℃~+80℃.

2.  IP67 protection capability: After the male end and female end of the connector are correctly connected in place, it can effectively isolate the dust and water, and ensure the safety and effectiveness of the electrical performance between the connected components, so it can safely work in wet, dust and other harsh environments.

3. Salt spray resistance: when the connector works in an environment containing moisture and salt, the surface treatment layer of the metal structure parts and contact parts may produce electrochemical corrosion, affecting the physical and electrical properties of the connector, and the tolerance time is at least 48 hours.

4. Vibration and impact resistance: this is an important performance of connectors, in special application environments such as aviation and aerospace, railway and highway transportation is particularly important, it is an important index to test the mechanical structure of electrical connectors and electrical contact reliability.

Fourth, General industrial connector structure

General industrial connectors are usually composed of four parts: insulator, pin (jack), bolt (nut) and cable.

(1) Insulator: used to maintain the fixed position of the combination and complete the electrical insulation between the combination of parts, requirements to have insulation ability, weather resistance ability, fire resistance, most of the design of nylon or TPU material.

(2) Pin jack: the circular needle or terminal is used to insert the parts of the socket combination (terminal or shrapnel), the selection of copper plating materials and processing methods, can improve the effectiveness of the combination, and can reduce the contact impedance.

(3) Bolts and nuts: in order to ensure that the plug socket has stable and good contact, the combination parts with prevent loose stop retreat in the structural design are usually treated with copper and nickel plating materials.

(4) Cable: such as multi-strand cable, coaxial cable, shielded wire, etc.
