Multifunctional connection socket for microphones

The socket has a dust cover (20) comprising rotary- (21), silicon rubber- (22) and covering- (23) parts. The rotary part has a side operating peg (30), a large central plug pin hole (32), small pin holes (33) and several curved slots (31). The silicon rubber part has a large cutout (40) and several fanned sections (41). Each has a small plug hole (42) and connection holes (43) spaced along the outer edge. The outer cover (23) includes a large cutout (50) and a large central plug hole (51). It has several side supports (53). The latter extend through the connecting holes of the silicon rubber part and the curved slots of the rotary part. They are screwed from within the main body (1). The operating peg of the rotary part extends through the large cut outs (40, 50) of the rubber- and covering parts, enabling manual turning, to close the small plug holes of the cylindrical part. This prevents dust ingress and adhesion inside.
