Grounding structure and rotary wireless network adapter

Abstract

The embodiments of the present invention disclose a grounding structure, which is applied to a rotary wireless access terminal. The wireless access terminal at least comprises: a structural component, a mainboard arranged inside the wireless access terminal of the structural component and a metal rotating shaft, the metal rotating shaft being connected with an external interface of the wireless access terminal; characterized in that the grounding structure comprises metal shrapnel and an insulating film; and one end of the metal shrapnel is connected to the metal rotating shaft, and the other end thereof is coupled and connected to the ground on the mainboard by means of the insulating film. The embodiments of the present invention also disclose a rotary wireless network card based on the above-mentioned grounding structure at the same time. By means of the technical solution in the embodiments of the present invention, an interference loop effect generated by a radio-frequency current flowing through the mainboard can be effectively eliminated, the problem of a poor low-frequency band performance of a built-in antenna is effectively solved, and the sensitivity of a low-frequency band antenna is improved.

Description

technical field [0001] The invention relates to wireless terminal product technology, in particular to a grounding structure and a rotary wireless network card. Background technique [0002] With the development of wireless broadband access technology and industry, wireless network cards, as an important part of wireless networks, can help users access wireless networks anytime and anywhere, so their business needs are becoming more and more extensive. At present, the user's requirements for the wireless network card are not only the performance of the wireless network card, but also higher and higher requirements for its appearance. [0003] Most of the current mainstream wireless network cards use a Universal Serial Bus (USB, Universal Serial BUS) interface, which can be divided into in-line wireless network cards and rotary wireless network cards. The in-line wireless network card usually adopts a cap design to prevent the USB interface from being exposed and easily dama...
