1The structural size of the connector: The overall size is very important. The connections in the product have certain space limitations, especially the connectors on the single board, which cannot interfere with other components. Appropriate installation methods should be selected based on the usage space and installation location: installation and fixation methods include screws, circlips, rivets, or quick locking of the connector's own locking pins, as well as straight or curved appearanceshapeTshapeCircleshape, Fangshape）Equal shape.

2. Connector shielding performance: With the development of communication products, connectors are receiving increasing attention. The selected connector requires a metal shell and the cable requires a shielding layer. The shielding layer should be connected to the metal shell of the connector to achieve shielding effect. Injection molding method can also be used to wrap the plug with copper sheet, and the shielding layer of the cable is welded together with the copper sheet.

3. Connector error proof plug design: Error proof plugs have two aspects: on the one hand, the connector itself rotates 180 degrees, causing signal connection errors. At this point, attention should be paid to selecting error proof plug connectors as much as possible, or assembling them independently by adjusting the relative position relationship of the connectors. On the other hand, in order to reduce the type of material, several signals should use the same connectors. At this point, the A plug may be inserted into the B plug. At this point, it should be noted that if this situation occurs, it can cause serious consequences.
