The industrial world has transitioned from mechanical control to electronic control, and is currently in the stage of digital transformation. It is very important to reasonably design the shape and size of connectors used in the industrial market. It must be designed according to standard specifications, because industrial connectors will affect the connectors. The rise of markets, smart factories and smart grids. The following is mainly to introduce the seven points of reasonable design of industrial connectors.

Industrial connectors

First, understand the functional requirements of the connector
It is especially important for connector suppliers to fully understand the needs of customers, and to manufacture connectors for suitable applications for customers.

Second, consider the stability of the connector
If you do not focus on the stability of the connector first, some factors may lead to increased costs. Because damaged industrial connectors need to be reconfigured, refurbished, and marked, and such changes may extend connector redesign time for another one to two weeks.

Third, understand the size of the connector space
Although the thickness of miniature board-to-board connectors is usually less than 1 mm, they are also commonly used in tightly packed applications. In order to solve potential packaging problems, designers need to consider the wiring on the PCB and the additional wires connected to the connector.

Fourth, consider the design stage of the connector
If you focus too much on the design of the overall system and consider industrial connectors in the final stage of design, some problems may make designers have to choose non-standard connectors to complete the design, which not only increases the cost, but also delays delivery time.

Fifth, determine the current load capacity of the connector
With the miniaturization of the connector size, the current load capacity of the connector is also reduced. The general miniature connector can handle the current between 200mA and 500mA, which is basically a larger board-to-board connector rated current Half, it is recommended to increase the number of connector terminals to compensate for the impact of the low current carrying capacity of the connector.

Sixth, consider the mechanical stress of the connector
Temperature, shock and vibration will generate stress between the connector interface and the circuit of the device. These mechanical stresses will affect the use of the connector. It is recommended to use an interconnect system to minimize the accumulated stress between the installation structure and the connection points.

Seven, consider the replaceability of the connector
If the appearance of the connector product is closed, you may need to be able to replace the connector from the outside, if soldering, it is relatively troublesome.
There are many factors that need to be considered in the design of industrial connectors. Designers need to consider not only the connector's packaging, durability, current load capacity, but also various factors such as the replaceability of the connector. After reading the above, I believe everyone should understand the seven points of rational design of industrial connectors.
