Embodiment 1

[0038] The rotating USB interface device provided by Embodiment 1 of the present invention has a structure such as Figure 8 , Figure 9 , Figure 10 As shown, among them, Figure 8 is the top view of the rotating USB interface device, Figure 9 For a side view of the device, Figure 10 A 3D rendering of the device. The rotating USB interface device includes: USB module 110 , first ground wire 120 in USB module 110 , rotating shaft 130 , conductive medium layer 140 , insulating medium layer 150 , PCB board 170 and grounding layer 160 on PCB board 170 . Here, it is taken as an example that the ground layer 160 is an exposed copper-clad ground area on the PCB 170 .

[0039]In the above-mentioned rotating USB interface device, the USB module 110 of the USB module 110 is rotated relative to the PCB board through the rotating shaft 130; wherein, the first ground wire 120 included in the USB module is connected with the rotating shaft 130, and the rotating shaft 130 is connecte...

Embodiment 2

[0043] The rotary USB interface device provided in the second embodiment of the present invention has the following structure: Figure 11 shown, where Figure 11 A side view of the device, the rotary USB interface device includes: a USB module 110 , a first ground wire 120 in the USB module 110 , a rotating shaft 130 , a conductive medium layer 140 , a PCB board 170 and a ground layer 160 on the PCB board 170 . The PCB board 170 is also used as an insulating medium layer, so it is not necessary to provide a special insulating medium layer 150 as in the first embodiment.

[0044] Therefore, in this embodiment, the USB module 110 , the first ground wire 120 , the rotating shaft 130 and the conductive medium layer 140 in the USB module 110 are arranged on the side of the PCB board 170 opposite to the ground layer 160 , so that the PCB board 170 can be used as the The purpose of the insulating dielectric layer. The first ground path of the USB module 110 formed by the conductiv...

Abstract

The invention discloses a rotating USB interface device, which comprises: a USB module realizes rotation relative to a PCB board through a rotating shaft; wherein, the first ground wire included in the USB module is connected to the rotating shaft, and the rotating shaft is connected to a conductive medium layer to form a The first grounding path of the USB module; an insulating medium layer is set between the grounding layer on the PCB board and the conductive medium layer to isolate the first grounding path from the second grounding path formed by the grounding layer of the PCB board. The grounding path of the PCB board and the USB module is isolated through the insulating medium layer to form an open circuit voltage and maintain a stable voltage difference, so that the entire device can obtain a stable grounding signal, improve the grounding performance, and improve the transmission and reception performance of the device.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a rotary Universal Serial Bus (Universal Serial BUS, USB) interface device in a terminal device. Background technique [0002] During the design process of data cards with rotary USB interfaces, how to ensure the goodness of the rotary USB interfaces is one of the necessary factors to determine the low frequency index of over the air (OTA) data cards. The OTA test can verify the connection ability of wireless devices and the network and the influence of wireless device users on radiation and receiving performance. OTA indicators include Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS) ) two indicators. TRP measures the radiation performance of a wireless device. The larger the TRP value, the better the radiation performance of the wireless device; the TIS measures the receiving performance of the wireless device. The smaller the TIS value, the bette...
