precautions for using dc socket

1. Please be careful not to confuse sockets with different specifications, because the specifications of the corresponding dc plug are also different. Therefore, in the use of dc USB, the corresponding dc plug should be selected according to the type of specification. The specification is not distributed, which may cause insertion failure or poor contact.

2. On the installation of dc socket, please check whether the dc USB is damaged or deformed in advance, such as whether the pin or substrate is damaged, in order to avoid short circuit or potential safety accidents in use.
