Headphone socket, radio frequency signal plug, communication terminal, matching structure and device

Abstract

Disclosed are an earphone socket, a radio-frequency signal plug, a communication terminal, a matching structure, and a device, which relate to the technical field of electronics, and are used to solve the problem that after a communication terminal is installed into a complete machine, a radio-frequency signal cannot be led out due to a built-in radio-frequency signal measurement interface. An earphone socket is arranged in a communication terminal; the earphone socket comprises an earphone jack and an earphone connection pin stretching into the earphone socket, and further comprises a first RF pin and a second RF pin stretching into the earphone socket, wherein the first RF pin and the second RF pin are located on the inner side of the earphone connecting pin, the first RF pin is used to be electrically connected to a radio-frequency signal end of the communication terminal, and the second RF pin is used to be electrically connected to an antenna end of the communication terminal. The embodiments of the present invention may be applied to a test of a radio-frequency signal of a communication terminal or a scenario, such as connecting a robot, in which a radio-frequency signal needs to be led out.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an earphone socket, a radio frequency signal plug, a communication terminal, a matching structure and a device. Background technique [0002] Communication terminals (such as mobile phones, tablet computers, etc.) with radio frequency communication functions have been widely used. Usually, there will be a radio frequency signal measurement interface on the main board of this kind of communication terminal. This radio frequency signal measurement interface is used to calibrate the radio frequency signal of the mobile phone during the production process, and at the same time, it is used to measure whether the radio frequency index of the mobile phone conforms to 3GPP (English) during the network access test. Full name: 3rd generation partnership project, Chinese full name: third generation partnership project) standard. [0003] In the process of realizing the present inventio...
