Description
Technical Field
The invention relates to the field of microwave transmission in the electronic industry, in particular to a multi-channel radio frequency sealing input-output device based on a BMA connector.
Background
Currently, in the field of microwave transmission in the electronic industry, a BMA connector is a radio frequency connector with blind insertion and floating characteristics, and is widely applied to microwave radio frequency signal transmission between a module and a chassis. The BMA connector is applied in an array mode between the module and the case, transmission of multiple paths of radio frequency signals can be achieved, and the module and the case can be connected and separated quickly due to the blind insertion characteristic of the BMA connector, so that the module can be conveniently installed in the case and detached and replaced. Meanwhile, the floating characteristic of the BMA connector enables all channels of the multi-channel radio frequency to still maintain phase consistency under the conditions of vibration and the like, so that the BMA connector can be applied to equipment with the phase consistency requirement. With further expansion of the application range of electronic devices, higher requirements are put on environmental adaptability of the electronic devices. For an electronic equipment cabinet applied outdoors, in order to prevent water vapor in air from entering the cabinet and having a harmful effect on components in the cabinet, the cabinet is generally designed to be a sealed cabinet. The chassis in the electronic device generally needs to input and output various signals, which requires that various signal input and output interfaces on the panel of the sealed chassis realize input and output of signals in a sealed manner.
However, in the present BMA connector application, the jack end (K end) is generally used as a fixed end, the pin end (J end) is used as a free end, and the jack of the fixed end is generally plugged by using the pin of the free end. Because the floating structure of the BMA connector is designed at the jack end, the inner core of the jack end connector can be jacked up when the pin end faces the jack end, and a gap exists between the inner core of the jack end connector and the shell. According to the current BMA connector application form, the jack end of the BMA connector is applied to the panel of the sealed case to serve as a fixed end, and when the pin end of the BMA connector and the jack end are inserted oppositely, the sealing performance of the case can be damaged by a gap generated by the jack end. This results in the inability to directly apply the BMA connector to the sealed chassis panel as a radio frequency input output interface in accordance with current BMA connector application formats. If the BMA connector is to be used, the sealed case needs to be internally provided with a rear mounting plate, the BMA connector is mounted on the rear mounting plate, the rear mounting plate is connected with the case panel through a radio frequency cable, and the case panel is connected with other connectors capable of realizing sealing to realize the input and output of radio frequency signals, so that the complexity and the material cost of the case are increased.

The invention aims at realizing the following scheme:
a multi-channel radio frequency sealing input/output device based on a BMA connector comprises a sealing machine case, and further comprises a BMA jack connector, a BMA pin connector and a sealing ring; the BMA jack connector is arranged on a quick plug-in module in the sealed case and used as a free end; the BMA contact pin connector is arranged on a panel of the sealed case and used as a fixed end; and meanwhile, a groove is arranged at the mounting position of the BMA contact pin connector on the panel of the sealed case, and the sealing ring is mounted in the groove.
Further, the BMA jack connector is composed of a shell and an inner core two-body structure.
Further, the BMA pin connector is of unitary construction.
Further, the seal ring comprises an O-ring seal.
Further, when the BMA pin connector arranged on the panel of the sealed case is plugged with the BMA jack connector arranged on the quick plug-in module, gaps are not generated, and meanwhile, the sealing ring plays a role in sealing the flange part of the BMA pin connector under the compression action of the BMA pin connector and the panel.
