Diving suit waterproof connector having lighting device

A diving suit waterproof connector having a lighting device, the waterproof connector comprising:

• a fixing tube part (10) watertightly connected to an end of a sleeve (1) of a diving suit (1-1), and
• a fastening tube part (20) connected to a neck portion of an underwater work glove (2) so as to be attached to/detached from the fixing tube part (10), wherein
• the fixing tube part (10) includes fastening protrusions (12) provided at equal intervals on an inner circumferential surface of a front end thereof, a rubber ring (14) press-fitted thereto so as to provide elasticity, and a first contact terminal (16) provided on the inner circumferential surface on which each of the fastening protrusions is formed, and
• the fastening tube part (20) includes coupling protrusions (22) provided at equal intervals on an outer circumferential surface thereof so as to hold and support the fastening protrusions (12) of the fixing tube part (10), a second contact terminal (24), being in contact with the first contact terminal (16), provided on the outer circumferential surface on which each of the coupling protrusions (22) is formed, and a lighting part (30) provided on one side of the fastening tube part and electrically connected to the second contact terminal (24) so as to emit light in front of the underwater work glove,
• wherein the lighting part includes:
• a housing (32) protruding from an outer circumference of the fastening tube part (20) and having a transparent or translucent window (31) at one side of the housing,
• an LED lighting unit (33) guided into the housing (32) and electrically connected to the second contact terminal (24) so as to emit light to the window,
• a contact switch (34) provided at one side of the housing so as to turn on and off the LED lighting unit (33), and
• a sealing material (35) press-fitted to an inner side of the housing (32) so as to protect the LED lighting unit (33), and
• wherein each of the plurality of fastening protrusions (12) provided at the equal intervals on the inner circumferential surface of the fixing tube part (10) has a circular arc-shaped rod structure along the inner circumferential surface of the fixing tube part (10),
• the rubber ring (14) of a ring shape is spaced apart from rear ends of the plurality of fastening protrusions (12) at a predetermined interval,
• each of the plurality of coupling protrusions (22) provided at the equal intervals on the outer circumferential surface of the fastening tube part (20) has a circular arc-shaped rod structure along the outer circumferential surface of the fastening tube part (20),
• a circular arc length of the coupling protrusion (22) is configured to be shorter than a circular arc length between the fastening protrusions (12) such that the coupling protrusion passes between the fastening protrusions (12), and
• a width of the coupling protrusion (22) in a forward/rearward direction thereof is configured to be larger than the interval at which the fastening protrusion (12) and the rubber ring (14) are spaced apart from each other,
• whereby the coupling protrusion (22) of the fastening tube part (20) is guided to be arranged between the fastening protrusions (12) of the fixing tube part (10) and then the fastening tube part (20) is pressed to the fixing tube part (10) and rotated, so that while a front end surface of the coupling protrusion (22) presses the rubber ring (14) of the fixing tube part (10), the coupling protrusion is fastened to the fastening protrusion so as to receive elasticity from the rubber ring (14), and an insertion protrusion (26) of the fastening tube part (20) is guided to a groove (18) of the fixing tube part (10) and combined therewith such that water from the outside is prevented from entering the diving suit (1-1) through the sleeve thereof.
