Description

Technical Field

[0001] This utility model relates to an output socket device, and more particularly to an output socket device for a dockside shore power box. Background Technology

[0002] After a ship docks, it needs to draw power from the shore power box at the dock via a dedicated ship / shore connector. Specifically, the shore power box at the dock is equipped with a socket for a dedicated ship / shore connector, while the ship draws power from the shore cable using a corresponding dedicated ship / shore connector plug.

[0003] In existing technology, the sockets on shore power boxes are typically fixed vertically to the box, and the plug must be inserted into the socket at a 90° angle. After insertion, the cable is pulled vertically down to the ground and bent, then extends along the ground. However, due to the height of the socket above the ground and the bending radius of the cable itself, the cable experiences significant stress at the bend point on the ground. This stress not only increases the difficulty of aligning the plug with the socket but also generates continuous torque after insertion, leading to accelerated wear on the plug pin and socket sleeve, thus significantly shortening the service life of the ship / shore connector and the cable.

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a dock shore power box output socket device.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a dock shore power box output socket device, including a variable angle base threadedly connected to the dock shore power box, the variable angle base being formed by changing the rear sequence connection angle, and a connection socket being fastened to the other end of the variable angle base, the connection socket being implemented by inserting and connecting a cable.

[0006] The variable angle base includes a cylindrical body and a large flange and a small flange located on both ends of the cylindrical body. The cylindrical body, the large flange, and the small flange are all provided with through holes.

[0007] Furthermore, the cylinder is a beveled cylindrical shape, and a large flange is connected to one side of the beveled surface of the cylinder. The size of the large flange is larger than the size of the beveled surface of the cylinder.

[0008] Furthermore, a base sealing gasket is installed between the large flange and the shore power box at the dock, and a through hole matching the through hole of the large flange is opened in the middle of the base sealing gasket.

[0009] Furthermore, the size of the small flange matches the size of the cylinder, and a socket sealing gasket is provided between the small flange and the connecting socket. The socket sealing gasket has a through hole that matches the through hole of the small flange.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-6As shown in the figure, this embodiment relates to the output socket device of the dockside power box, which is used to change the connection angle of the cable, specifically including:

[0023] The device includes a variable-angle base 1 that is threadedly connected to a shore power box at a dock. The shore power box is an existing technology. Traditional shore power boxes do not have the output socket disclosed in this application. Therefore, traditional shore power boxes have connection openings. In this embodiment, a threaded variable-angle base 1 is added on this basis. As disclosed by the name of the variable-angle base 1, the variable-angle base 1 is formed by changing the connection angle of the rear-end sequence, that is, it is used to change the angle of the rear-end connection structure, thereby changing the connection angle of the cable. Furthermore, the other end of the variable-angle base 1 is fastened to a connection socket 3. The connection socket 3 is implemented by inserting the cable, so the connection angle of the cable can be changed.

[0024] like Figure 1-2 As shown, the variable angle base 1 includes a cylindrical body 5 and a large flange 6 and a small flange 7 located on both ends of the cylindrical body 5, respectively. The cylindrical body 5, the large flange 6, and the small flange 7 are each provided with the following... Figure 3 Via 8 shown.

[0025] In this embodiment, the angle between the output socket device of the dock shore power box and the dock shore power box does not exceed 30°. Specifically, the angle between the side extension line of the cylinder 5 of the variable angle base 1 and the side wall of the dock shore power box does not exceed 30°. Indirectly, the angle between the cable and the dock shore power box does not exceed 30°.

[0026] like Figure 1-2 As shown, the cylinder 5 is a beveled cylindrical shape, and the large flange 6 is connected to one side of the beveled surface of the cylinder 5. The size of the large flange 6 is larger than the size of the beveled surface of the cylinder 5. A base sealing gasket 2 is provided between the large flange 6 and the shore power box. The center of the base sealing gasket 2 has a through hole that matches the through hole 8 of the large flange 6, so as not to affect the transmission of cables. The base sealing gasket 2 is used to strengthen the connection between the variable angle base 1 and the shore power box.

[0027] like Figure 2 As shown, the size of the small flange 7 matches the size of the cylinder 5. A socket sealing gasket 4 is provided between the small flange 7 and the connecting socket 3. The socket sealing gasket 4 has a through hole that matches the through hole 8 of the small flange 7, so as not to affect the transmission of the cable. The socket sealing gasket 4 is used to strengthen the connection between the connecting socket 3 and the reinforced variable angle base 1.

[0028] Regarding the connector 3, the connector 3 in this application is a specially customized product, such as... Figure 6As shown, the connection socket 3 includes a mounting base 9 that abuts against the socket sealing gasket 4. In this embodiment, the shape of the socket sealing gasket 4 matches the mounting base 9 to further enhance the connection stability. In addition, for the purpose of connection stability, the socket sealing gasket 4 can also be threaded onto the mounting base 9. This application does not limit the shape of the socket sealing gasket 4 or the connection method between the socket sealing gasket 4 and the mounting base 9. This is hereby stated.

[0029] Preferably, the mounting base 9 is provided with a cable take-up connector 11 that matches the through hole of the socket sealing gasket 4. The cable take-up connector 11 has a through hole for taking up the cable. The cable take-up connector 11 is implemented in such a way that it passes through both sides of the mounting base 9. The portion of the cable take-up connector 11 that passes through the through hole of the socket sealing gasket 4 extends into the through hole 8 of the small flange 7.

[0030] Preferably, the mounting base 9 has an outwardly protruding support ear 10 on the side away from the socket sealing gasket 4. The height of the protrusion of the support ear 10 matches the extension length of the cable take-up connector 11 on that side. The cable take-up connector 11 has a plug-in interface 20.

[0031] Furthermore, the corner of the support ear 10 is rotatably connected to the protective cover 12 of the matching plug interface 20 via the cover pin 13. Therefore, in actual use, the operator can apply force to rotate the protective cover 12 via the cover pin 13 to place it on the plug interface 20 or rotate it open. The protective cover 12 protects the plug interface 20 in the non-use state and prevents corrosion, foreign object intrusion and other problems. In addition, locking pins 14 are provided on both sides of the protective cover 12.

[0032] The two sides of the connector 20 are respectively rotatably connected to corresponding first flip push-pull rods 15 and 16. A hand grip 19 is provided between the free ends of the first flip push-pull rods 15 and 16. Therefore, the movement of the first flip push-pull rods 15 and 16 is a flip with the axis as the rotation point. Due to the presence of the hand grip 19, the movement of the first flip push-pull rods 15 and 16 is synchronized. The operator can flip the first flip push-pull rods 15 and 16 by holding the hand grip 19 and applying force. In the non-use state, the protective cover 12 covers the connector 20, and the first flip push-pull rods 15 and 16 are flipped up and protected outside the protective cover 12.

[0033] Preferably, both the first flip push-pull rod 15 and the first flip push-pull rod 16 have locking grooves 17 on opposite sides that match the locking pin 14, such as... Figure 7As shown, in the non-use state where the protective cover 12 is on the insertion interface 20, the operator further grasps the handle 19 and applies force to simultaneously flip the first flip push-pull rod 15 and the first flip push-pull rod 16 downwards. The locking pin 14 then enters the locking groove 17 and is firmly locked. Thus, the protective cover 12 is locked in the closed state before the first flip push-pull rod 15 and the first flip push-pull rod 16 are flipped upwards. Figure 8 As shown, when the first flip push-pull rod 15 and the first flip push-pull rod 16 are flipped up and protected outside the protective cover 12, the locking pin 14 enters the through groove 18 to limit and lock, preventing the first flip push-pull rod 15 and the first flip push-pull rod 16 from disengaging and closing under non-flipping external force.

[0034] This application discloses an output socket device for a dockside power distribution box. When connecting the cable plug to the output socket device of this application, the connection angle of the cable is changed. It is no longer the traditional method of vertically descending to the ground, but forms a specific angle, namely, no more than 30° as defined in this application. In this case, the cable is no longer limited by the minimum radius of curvature, and the reaction force borne by the plug and the output socket device is significantly reduced. The cable exhibits a natural bending state, making contact with the ground more flexible, and the insertion process of the plug is also more effortless. In addition, the wear between the cable and the ground, and between the plug and the output socket device, is reduced, thereby improving the service life of the output socket device and the cable.

[0035] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
