A radio frequency seat device, circuit board and mobile terminal

Abstract

The invention discloses a radio frequency base device, a circuit board and a mobile terminal. The radio frequency base device comprises a radio frequency line joint part and a radio frequency base conductive core. The radio frequency line joint part is equipped with an opening. According to the opening, a test probe of a test line is inserted through the opening and is electrically connected with the radio frequency base conductive core. The on-off of electric connection between the radio frequency base conductive core and a radio frequency line inner core is controlled by changing the relative positions of the radio frequency line joint part and the radio frequency base conductive core. According to the radio frequency base device, the circuit board and the mobile terminal, the structure of an existing radio frequency base by referring to the structure principle of a test base, the functions of the test base and the radio frequency base are integrated, equivalently, the radio frequency base is moved from the interior of the circuit board to the radio frequency line joint position out of the circuit board. Through adoption of the technical scheme provided by the invention, the test base does not need to be arranged in the circuit board, the cost is reduced, and the device layout space in the circuit board is increased.

Description

technical field [0001] The invention relates to the technical field of mobile terminal radio frequency, in particular to a radio frequency seat device, a circuit board and a mobile terminal. Background technique [0002] At present, the development of mobile terminals such as mobile phones is increasingly pursuing lightness and thinness. As a thin and light model, the solution of using broken boards for internal stacking has certain advantages. Under the plan of breaking the board, the antenna signal transmission in the board and the antenna signal transmission between the boards are realized through the radio frequency line and the radio frequency seat. Compared with the FPC (Flexible Printed Circuit, flexible circuit board), the advantage of the signal transmission is the signal attenuation Relatively small, and the built-in antenna signal itself is weak. Near the RF socket, there is always a test socket for in-board testing when debugging the antenna. The test socket on...

AI Technical Summary

Problems solved by technology

The test socket only works for a short period of time during the test, and has no effect when the actual user uses it, and the efficiency is low

The disadvantages of this solution are: 1. The test seat occupies the area of ​​the inner board, and 2. The cost of the inner board is increased.
