[0024] Hereinafter, embodiments of the present invention having the aforementioned features will be described in more detail with reference to the attached drawings.

[0026] A cylindrical cable connector for underwater equipment according to an embodiment of the present invention comprises: a cylindrical connector housing body (110) formed through a main body frame (10) that covers underwater communication equipment, measuring equipment, or electronic equipment in a watertight manner, and inserted into and coupled to a connector hole (11) into which a power cable (20) is introduced, and having a hollow formed to allow the power cable (20) to pass through; a plug socket (120) electrically connected to the power cable (20) and extended at the front end of the connector housing body (110); a tool catch portion (130) each chamfered on both sides of the front end of the connector housing body (110); one or more rows of first O-ring coupling grooves (140) formed at the rear end of the connector housing body (110); a first O-ring (150) interposed between a second O-ring coupling groove (12) formed in the connector hole (11) corresponding to the first O-ring coupling groove (140); and a plug that is fastened to the plug socket (120) and plugged in to be electrically connected. The gist of the invention is to align the plug socket (120) and the plug cord (160) by rotating the connector housing body (110) through a tool attached to the tool catch portion (130) while in a watertight state by the first O-ring (150), including a plug cord (160) in which a pin (161) is formed at the front and rotation is restricted to another body frame.

[0028] Hereinafter, with reference to the drawings, the cylindrical cable connector for underwater equipment with the aforementioned configuration will be specifically described as follows.

[0030] First, referring to FIGS. 2 to 4, the connector housing body (110) is formed in a hollow cylindrical shape so that the power cable (20) is inserted and coupled into a connector hole (11) formed through the body frame (10) which is formed to watertightly cover and house underwater communication equipment, measuring equipment, or electronic equipment that requires external power connection or communication connection, and the power cable (20) passes through and is connected to a plug socket (120).

[0031] Here, the power cable (20) may be an umbilical cable that includes a cable for equipment control or a cable for monitoring.

[0033] Next, the plug socket (120) is a socket formed with 2, 3, or 4 holes corresponding to the 2, 3, or 4 pins of the plug cord (160), and with reference to FIGS. 2 to 4, it is electrically connected to the power cable (20) and extends and protrudes from the front end of the connector housing body (110).

[0035] Next, the tool catch portion (130), with reference to FIGS. 2 and FIGS. 4, is chamfered on both sides of the front end of the connector housing body (110), so that the connector housing body (110) can be rotated from the body frame (10) through a tool (30), such as a spanner, which is attached to the tool catch portion (130), so that the plug cord (160) with limited rotation is aligned and the pin of the plug cord (160) and the hole of the plug socket (120) are engaged so that the plug socket (120) can be electrically connected.

[0036] Here, although not shown, a tool coupling groove is formed in the vertical direction in the tool catch portion (130), and a screwdriver or the like is inserted into the tool coupling groove to rotate the connector housing body (110), so that a screwdriver or the like can be easily used in cases where it is difficult to use a tool (30) such as a spanner due to spatial constraints.

[0038] Next, with reference to FIGS. 3 and 4, the first O-ring coupling groove (140) is formed in one or more rows at the rear end of the connector housing body (110), and the first O-ring (150) is interposed between the second O-ring coupling groove (12) formed on the inner circumference of the connector hole (11) corresponding to the first O-ring coupling groove (140), thereby blocking moisture penetration into the interior and ensuring watertightness to secure electrical safety when the connector housing body (110) rotates in the connector hole (11) of the main body frame (10).

[0040] Next, the plug cord (160) is configured to be connected to an umbilical cable that cannot rotate on its own, or to be connected to another main body frame (not shown) with limited rotation. Referring to FIGS. 2 and 4, a plug pin (161) is formed at the front end to be plugged into a plug socket (120) to be electrically connected.

[0041] Here, an O-ring (not shown) may be coupled to the inner surface of the plug cord (160) and the outer surface of the plug socket (120), so that, for example, the O-ring coupled to the outer surface of the plug socket (120) may be watertight when the plug socket (120) and the plug cord (160) are connected.

[0043] Through the aforementioned configuration, in a watertight state between the main body frame (10) and the connector housing main body (110) by the first O-ring (150), the connector housing main body (110) is rotated by means of a tool attached to the tool catch (130) to align the plug socket (120) and the plug cord (160), so that the plug cord (160) can slide forward and backward within a certain length range and the plug socket (120) can rotate, thereby allowing the plug socket (120) to be rotated in a watertight state without detaching the plug socket (120) from the main body frame (10) to align with the plug cord (160).

[0045] Additionally, referring to FIGS. 2 to 4, a stopper (111) is formed protruding at a certain height from the outer surface of the connector housing body (110) at the front end of the first O-ring coupling groove (140), so that, as in FIG. 3, the stopper (111) is in close contact with the main body frame (10) to prevent the connector housing body (110) from being pushed backward by the plug cord (160).

[0046] Here, a sealing (not shown) may be interposed between the stopper (111) and the main body frame (10) to reinforce watertightness, or a slip prevention pad (not shown) may be attached to limit rotation of the connector housing main body (110) due to unexpected external force.

[0048] Meanwhile, referring to FIGS. 5 to 7, another example of a cylindrical cable connector for underwater equipment is described in detail as follows.

[0049] A contact plate (170) is formed at the rear end of the connector housing body (110) and is in close contact with the rear end of the body frame (10), and a third O-ring coupling groove (171) is formed therein. A second O-ring (180) is interposed between the rear end of the body frame (10) and the third O-ring coupling groove (171), so that electrical safety can be reinforced by creating a double watertight seal through the first O-ring (150) and the second O-ring (180).

[0050] Additionally, referring to FIGS. 6 and 7, a screw thread (112) is formed on the outer surface of the connector housing body (110) corresponding to the front end of the first O-ring coupling groove (140), and the connector housing body (110) is watertightly fixed to the main body frame (10) by mutual contact between a nut (113) and a contact plate (170) that are screwed into the screw thread (112), thereby preventing the connector housing body (110) from detaching due to external forces such as vibration, and the second O-ring (180) can be compressed to further increase watertightness.

[0051] Here, although not illustrated, an O-ring coupling groove and an O-ring may be coupled on the opposite surface of the nut (113) facing the main body frame (10), so that when the nut (113) is fastened, the O-ring is compressed to further increase watertightness.

[0052] Additionally, the contact plate (170) may be formed integrally with the connector housing body (110), but, although not illustrated, it may be coupled to the rear end of the connector housing body (110) by screw fastening, thereby allowing the fastening position of the contact plate (170) to be adjusted according to the thickness of the body frame (10).

[0054] Accordingly, by configuring the cylindrical cable connector for underwater equipment as described above, the connector housing body can be rotated using a tool such as a wrench while in a watertight state with an O-ring to align the plug socket and the plug cord, thereby electrically connecting to the plug cord in a watertight state without the plug socket detaching from the body frame, and electrical safety can be ensured by further enhancing watertight performance through a double watertight structure with a nut, a sealing plate, and an additional O-ring.

[0056] The embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; therefore, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.
