Consideration of connectors in 7-point circuit design

       The importance of a connector depends on its size, and the smaller it becomes, the greater its importance.

       The reason is simple: many products are shrinking. Nowadays, countless electronic devices, such as smart phones, tablets and blood glucose detectors, have more and more strict requirements on size, and the internal structure arrangement is more and more dense, so there is not much space for connectors. This trend also appears in the field of national defense and aerospace. For example, in satellites, guided missiles and avionics systems, only micro connectors can meet the requirements of compactness.

       With the increasing demand for small connectors, design engineers are facing a series of new challenges. In the project, they can no longer put the connector design in the final stage. Miniature connectors require more careful design. This requires designers to consider various factors in advance in terms of packaging, durability, current load capacity and replaceability.

       The designer shall consider easy replacement, especially in a closed enclosure.

The following are some design suggestions provided by micro connector manufacturers. This suggestion is not only from professional connector designers, but also the experience summary hated by designers, so it is worthy of reference for designers.

1. Consider connectors early in the design

2. Understand space constraints

3. Understand the current load capacity

4. Consideration of stability of small / micro connection

5. Consideration of replaceability

6. Understand the functional requirements of the connector

7. Consider mechanical stress
