Description

Radio frequency adapter with switch Technical Field The utility model relates to the technical field of electric connectors, in particular to a radio frequency adapter with a switch. Background The fixed end inner conductor and the test end inner conductor of the existing radio frequency converter are always connected together, signals are transmitted from the fixed end to the transfer end in a non-test state, because the fixed end inner conductor is always connected with the test end inner conductor, resonance gradually affects the transmission of the whole signals along with the increase of frequency, most of data of 3GHz or 6GHz voltage standing wave ratio can be obviously risen through the test of the transmission line from the fixed end to the transfer end (generally, 3GHz or 6GHz is considered to be the cut-off frequency of the converter), the application frequency and the installation mode of electronic products in the market are required to be higher and higher, the application frequency requirement is up to 12GHz, and the existing radio frequency converter cannot reach the frequency range. Disclosure of utility model Based on the technical problems, the embodiment of the application provides a radio frequency adapter with a switch, which can greatly improve the anti-resonance capability of the whole adapter and effectively improve the cutoff frequency of a product to be more than 12 GHz. In order to achieve the aim, the technical scheme adopted by the utility model is that the radio frequency adapter with the switch comprises a shell, a switch and a switch, wherein the shell comprises a test end, a fixed end and a switching end, the inner cavity of the test end is communicated with the fixed end, and the switching end is arranged between the test end and the fixed end and is provided with an upward opening; The inner cavity of the testing end is provided with a first inner conductor which is fixed in the testing end through a first insulating medium; the switching shell is arranged above the switching end, and is arranged on the opening, a second inner conductor is arranged in an inner cavity of the switching end and is fixed in the switching end through a second insulating medium; The first inner conductor is internally provided with a first spring, the end part of the first spring is connected with a fourth insulating medium, the end part of the third inner conductor is provided with a second spring, the end part of the second spring is connected with a movable contact pin, and the movable contact pin is connected with the fourth insulating medium in an opposite-plug manner.
