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 aforementioned rotary USB interface device, the USB module 110 of the USB module 110 can rotate relative to the PCB board through the rotating shaft 130; wherein, the first ground wire 120 included in the USB module is connected to the rotating shaft 130, and the rotating shaft 130 is connected to ...

Embodiment 2

[0043] The rotating USB interface type device provided by Embodiment 2 of the present invention has a structure as follows: Figure 11 shown, where Figure 11 It is a side view of the device, and the rotating 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 grounding layer 160 on the PCB board 170 . Wherein the PCB board 170 is also used as an insulating medium layer at the same time, 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 as to realize that the PCB board 170 serves as The purpose of the insulating dielectric layer. The first ground path of the U...

Abstract

The invention discloses a rotatable USB (Universal Serial Bus) interface equipment. The equipment is characterized in that a USB module can rotate relative to aPCB (printed circuit board) by a spindle, wherein a first earth wire in the USB module is connected with the spindle and the spindle is connected with a conducting medium layer, thus a first grounded circuit of the USB module is formed; an insulating medium layer is arranged between a grounded layer on the PCB and the conducting medium layer and insulates the first grounded circuit from a second grounded circuit formed by the ground layer of the PCB. Since the insulating medium layer isolates the grounded circuits of the PCB and the USB module,, an open-circuit voltage can be formed for maintaining the stable voltage difference, so that the whole equipment can obtain stable ground signaling, thereby improving the grounding performance and transmitting and receiving performance of the equipment.

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...
