specific Embodiment 2

[0026] A specific embodiment 2 of a rotary connector of the present invention, the difference between the structure of the rotary connector in this embodiment and the specific embodiment 1 of the above-mentioned rotary connector is only that: figure 2 As shown, the rotary connector housing of the rotary connector is not equipped with a pressure balance mechanism, and the pressure difference between the inside and outside of the sealed cavity is only reduced by filling the sealed cavity with an insulating pressure-bearing medium, such as filling the sealed cavity with transformer oil , because the transformer oil can achieve internal and external pressure balance under the condition of small deformation. In a very small case, the internal and external balance of the sealing cavity can be realized, so that the pressure difference between the internal and external pressures is reduced so that the dynamic sealing components are not damaged or invalidated.

Abstract

The invention relates to the field of connectors and especially to a rotary connector. The rotary connector comprises a rotary connector housing and a sealed cavity defined by the rotary connector housing. A signal conversion device is disposed in the sealed cavity and comprises a signal input shaft. The signal input shaft is assembled on the rotary connector housing in a rotating sealed way. The rotary connector housing also comprises the sealed cavity defined by rotary connector housing and used for being filled with a liquid insulating medium. The signal conversion device is disposed in the sealed cavity. The rotary connector solves a problem that the motive seal member of a conventional rotary connector is liable to damage.

Description

technical field [0001] The invention relates to the field of connectors, in particular to a rotary connector. Background technique [0002] When the sealing cover of the equipment working underwater is opened, it is necessary to detect the unscrewing angle of the sealing cover. Usually, an encoder that converts the rotation angle of the sealing cover into an electrical signal output is connected to the rotating shaft of the sealing cover. The encoder is a mechanical The signal conversion device that converts the rotation signal into an electrical signal is used to feedback the unscrewing angle of the sealing cover, and the equipment can proceed to the next step after the sealing cover is unscrewed. When the sealing cover of the equipment is opened, the encoder has to withstand a large water pressure impact. Generally, the rain-proof or unipolar sealing structure of the encoder itself cannot meet the strong water pressure, which will cause water to enter the encoder and cause...
