Near-field communication antenna device

Abstract

The invention discloses a near-field communication antenna device, and relates to the technical field of communication, in particular to a near-field communication antenna device. The near-field communication antenna device comprises a metal buckling sheet and a comprehensive blocking outer shell, wherein the top part of the metal buckling sheet is fixedly connected with portable sliding plates which are symmetrically distributed. According to the near-field communication antenna device, a hollow groove is formed in the comprehensive blocking outer shell, the inner wall of an inner cavity of the comprehensive blocking outer shell is fixedly connected with an anti-permeation fixed film; meanwhile, symmetrically distributed vertical threaded columns are fixedly connected to the interior of the comprehensive blocking outer shell; the exterior of the vertical threaded columns is fixedly connected with thin-layer heat insulation top plates which are symmetrically distributed; and thin-layerheat insulation auxiliary plates which are oppositely distributed are fixedly connected to the inner side of the thin-layer heat insulation top plate, by buckling the parts with one another, externalsteam can be guaranteed not to influence a coil conductor in the near-field communication antenna device in the using process, and then the problem that an existing device cannot block steam is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a near-field communication antenna device. Background technique [0002] Near-field communication technology is a short-range high-frequency wireless communication technology with a usable distance of about ten centimeters. At the same time, it can realize electronic identification or data transmission, such as credit cards and access cards. Users can use the NFC The antenna device can be used for non-contact office work, especially the display and preview of some products, which can be realized by using near-field communication, so people need a near-field communication antenna device in their daily life.

Problems solved by technology

[0003] At present, most of the existing near-field communication antennas on the market are directly fixed on the outside of the coil conductor and connected to the external protective shell. The airtightness of this arrangement is poor. Air can easily enter the inside of the coil conductor, which will damage the near-field communication antenna. There are also some devices that directly connect the coil conductor to the outside of the circuit board layer of the device. This setting will cause the circuit inside the device to be affected by the magnetic field of the coil conductor. In addition, most of the existing near-field communication antennas are installed inside the mobile phone. During the process of using the mobile phone, the mobile phone will often be accidentally dropped, or the mobile phone will be partially overheated when it is used for a long time. , and then the coil conductor is damaged, so we propose a near-field communication antenna device
