Industrial connectors are electromechanical components used to connect wires, cables, and control boards (bins). As a very important electronic component, it is widely used. In order to help you have a deeper understanding, this article will summarize the role of industrial connectors and design points related knowledge. If you're interested in what this article is about to cover, read on.
What role does the industrial connector play? What are the key points of design?
First, industrial connector design points.
1. Understand the functional requirements of connectors
Suppliers need customers to fully express their needs, otherwise they may misunderstand the needs of customers. This is especially important when you need to build custom connectors.
2. Consider mechanical stress
Temperature, shock and vibration can create stresses between interfaces and circuits. Select connectors that are designed to avoid these forces. Use an interconnect system to minimize built-up stress between mounting structures and connection points.
3. Make clear the current load capacity
As the connector size decreases, the current load capacity of the connector decreases. In general, miniature connectors can handle currents between 200mA and 500mA, which is about half the current rating of larger board-to-board connectors. To compensate for the lower current-carrying capacity, the designer may need to increase the number of terminals.
4. Consider connectors early in your design
"Engineers tend to focus too much on designing the overall system and leave the industrial connectors to the very end of the design process. Then they get stuck on their own design." Designers eventually had to choose non-standard connectors to complete the design, which not only drove up costs but also delayed delivery times.
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 address potential packaging issues, designers need to consider the wiring of the PCB board and the additional wires that are attached to the connectors.
6. Consider the stability of small/micro connections
If the problem is not taken to heart first, it could drive up costs, he said. Damaged industrial connectors need to be reconfigured, refit, and marked. It may even need to be replaced by more expensive, field-replaceable connectors, and such changes may add another week or two to the design time.
7, consider the ease of replacement
If the exterior of the product is closed, then you need connectors that can be replaced from the outside. Otherwise, you'll need to do some welding.
Micro connectors require forethought. It requires the designer to consider a wide variety of factors in advance, such as packaging, durability, current load capacity, and replaceable.
Two, the role of industrial connectors
The role of industrial connectors is mainly used to realize the transmission and control of electrical signals and the power connection between electronic and electrical equipment. It can be inserted and separated between the connector plug and the socket, so that the circuit is switched on and off. Connectors are required to reliably conduct and connect circuits, transmit information, and perform specific functions under various environmental conditions. Their reliability directly affects the reliability of engineering systems such as equipment and products. In some harsh working conditions, such as industrial manufacturing environment, outdoor environment and other relatively harsh environment, it is necessary to use the aviation plug with more excellent environmental performance to undertake the high reliable connection of power supply, signal and data.
This article can only lead you to have a preliminary understanding of the industrial connector, I hope it will be of some help to you, and need to continue to summarize, so as to improve professional skills, but also welcome you to discuss some knowledge points of the article.
