Waterproof connectors are essential components in electronic devices. If you observe the current flow path, you will always find one or more connectors. The form and structure of connectors are constantly changing. There are various waterproof connectors available according to different application objects, frequencies, power, and application environments.

Waterproof connectors can not only connect current, but also in today's rapidly developing optoelectronic technology, the carrier of signal transmission in optical fiber systems is light. Glass and plastic have replaced wires in ordinary circuits, but connectors are also used for optical signal pathways, and their functions are the same as circuit connectors.

Shenzhen Dongshengda, as a reliable waterproof connector manufacturer, has been widely used in the electronic manufacturing industry and can meet various needs.
