Radio frequency device

Abstract

The invention provides a radio frequency device, which comprises a shell, a circuit board, an antenna, a signal transmission line and a connecting piece, wherein the circuit board is arranged in the shell; the antenna is arranged outside the shell; the signal transmission line is used for connecting the circuit board with the antenna; one side surface of the shell is provided with a jack; the antenna comprises an antenna body and a plugging part with a line hole, wherein the plugging part is connected with the antenna body; the cylindrical surface of the plugging part is provided with a lug; the connecting piece is similar to a ladder cylinder shape; the connecting piece comprises a through hole, a plug and a containing cavity, wherein the plug comprises a restriction part which can prevent the connecting piece from rotating around the axis on the ladder trend; the wall of the containing cavity is provided with a ring slot; the plug can be cooperatively plugged into the jack; the plugging part is arranged in the containing cavity in a transition fit mode; the lug is clamped into the ring slot; and the antenna body is connected to the circuit board via the signal transmission line. According to the radio frequency device disclosed by the invention, the connection mode of the antenna and the radio frequency device is optimized, and the cost is lowered, thereby being convenient for large-scale production and manufacture.

Description

technical field [0001] The invention belongs to the field of communication equipment, and in particular relates to a radio frequency device. Background technique [0002] In recent years, with the development of wireless communication, radio frequency devices have been widely used, and radio frequency devices transmit and receive wireless signals through antennas. Wireless signals use radio frequency technology. In order to obtain better communication effects, sometimes it is necessary to adjust the direction of the antenna to obtain the best radiation angle. [0003] In order to achieve a better communication effect, the current radio frequency equipment uses an external antenna, and often uses a coaxial connector to connect the antenna and the radio frequency equipment to transmit radio frequency signals. The basic structure of the coaxial connector includes: a central conductor, The dielectric material (insulator) outside the inner conductor and the outermost outer conta...
