Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1-3, the utility model provides a high protective USB device, which comprises a housing 1, a PCB2, and a rear cover 3; the PCB2 is also provided with a protective shell 4; the PCB2 is partially arranged in the protective shell 4; the PCB2 is adhered to the protective shell 4; the protective shell 4 is adhered to the shell 1; the rear cover 3 is adhered to the housing 1 to form a closed whole. A plurality of electronic components 203 are welded on the PCB2, one end of the PCB2 is provided with a press switch 201 used for controlling data reading of the USB equipment, and the other end of the PCB2 is provided with a golden finger 202 used for supplying power and transmitting signals, so that the USB equipment realizes data reading and transmission.

As shown in fig. 4, the protective shell 4 encapsulates the thermal conductive adhesive into a mold to form the gaps between the electronic components 203 of the PCB2 except the gold finger 202 and the push switch 201, the thermal conductive adhesive completely fills the gaps between the electronic components 203, so that the electronic components 203 are protected from being broken, and meanwhile, the thermal conductive adhesive also has good thermal conductive performance, and in the using process, the thermal conductive adhesive transmits heat generated by the electronic components 203 to the shell 1 for heat dissipation, thereby avoiding the damage caused by the heating and scalding of the electronic components 203 due to long-time use.
