There are Seven Major Things to Note When Designing Industrial Connectors.
The smaller the connector becomes, the more important it is. The reason is simple: the products are getting smaller. Nowadays, countless electronic devices such as smartphones, tablets, and blood glucose detectors are becoming more and more strict in size, and the interior is getting closer and closer, so there is not much room left for industrial connectors.
1. Understand the functional requirements of the connector
Suppliers need customers to fully express their needs, otherwise they may misunderstand customer needs. This is especially important when you need to make a custom connector.
2. Consider mechanical stress
Temperature, shock and vibration create stress between the interface and the circuit. Choose connectors that avoid these forces. Use an interconnect system to minimize accumulation stress between the mounting structure and the connection points. “There are many suppliers that offer such systems.”
3. Find out the current load capacity
As the size of the connector decreases, the current carrying capacity of the connector also decreases. In general, miniature connectors can handle currents between 200mA and 500mA, which is about half the larger current rating of board-to-board connectors. In order to compensate for the problems caused by the lower current carrying capacity, the designer may need to increase the number of terminals.
4, consider the connector in the early design
“Engineers tend to focus too much on designing the overall system, and putting the industrial connectors into the final stages of design. Then they are stuck by their own designs.” The designer finally had to choose a non-standard connector to complete the design. This not only raises costs but also delays delivery time.
5. Understand the limitations of space
Although miniature board-to-board connectors are typically less than 1 mm thick, they are also commonly used in tightly packed applications. To solve potential packaging problems, designers need to consider the traces on the PCB and the additional wires attached to the connectors.
6. Consider the stability of small/micro connections
If you don't focus on this issue first, it may push up costs, he said. Damaged industrial connectors require reconfiguration, refurbishment and marking. It may even require a more expensive, field-replaceable connector to replace, and such changes may extend the design time by another one to two weeks.
7. Consider easy replacement
If the appearance of the product is closed, then you need a connector that can be replaced from the outside. Otherwise, you will need to do some welding work.
Micro connectors need to be farsighted. It requires designers to anticipate various factors such as packaging, durability, current load capability, and interchangeability.
