Description

Technical Field

[0001] The utility model relates to the technical field of shore power plugs and sockets, and particularly relates to a connection mechanism of a shore power plug and socket. Background Art

[0002] Shore power plugs are widely used in mines, docks, ports, wharves and the steel manufacturing industry with harsh environments. Previously, ships docked at docks, ports and locks had to generate electricity using ship auxiliary engines 24 hours a day to meet the electricity demand of the ships. The technology of connecting ships to shore power means that during the period when the ship is docked at the port, the generator on the ship is stopped and land power is used instead. The power provided by the port for shore power should be able to ensure that all the necessary electrical facilities on the ship can meet the electricity demand after docking.

[0003] There is a prior art with the publication number CN209571640U and the name of a connection mechanism of a shore power plug and socket. The connection mechanism includes an embedding groove on the socket body. A guiding groove is provided on the inner wall of the embedding groove and corresponds to a guiding boss at the head end of the plug body. An arc groove is provided at the rear side of the guiding boss, and the arc groove can embed a positioning ball on the socket body. When the plug and socket are inserted and combined, the guiding boss on the plug is aligned with the guiding groove on the socket, so that the plug is inserted into the embedding groove of the socket. When the plug is inserted in place, the positioning ball embeds into the arc groove to position the plug. Through the guiding of the guiding boss and the guiding groove, and the precise positioning of the positioning ball and the arc groove, the head of the plug can accurately insert into the embedding groove of the socket and be precisely positioned, with easy insertion, small insertion and separation force, accurate positioning and convenient operation.

[0004] However, the above shore power plug and socket are plugged and fixed. The shore power connection operation is completed by the corresponding clamping connection of the guiding boss on the plug and the guiding groove on the socket. However, the plug and the cable connected to the rear of the plug are often relatively heavy, and there is a lack of a pressing connection component when the plug is connected to the socket. Under the action of the gravity of the cable, the plug is likely to fall off and separate from the socket, affecting the normal charging of the ship and reducing the charging efficiency of the ship. Content of the Utility Model

[0005] The utility model solves the problems in the related art and provides a connection mechanism of a shore power plug and socket.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions: A connection mechanism for a shore power plug and socket, comprising a support member, a moving member, and a distribution box. The support member includes a sliding frame. A plurality of fixing screws are vertically threaded through and assembled at the bottom end of the sliding frame. And a socket is horizontally arranged in the middle of the bottom surface of the sliding frame. The socket is vertically clamped with a plug. A distribution box is vertically arranged at the top end of the sliding frame. And a top frame is vertically fixed at the bottom end of the distribution box. The top frame is fixed on the top end surface of the sliding frame. A moving member is horizontally arranged in the sliding frame. The moving member includes a moving slide bar. The moving slide bar is vertically slidably assembled in the sliding frame. And a socket is penetrated and assembled in the middle of the moving slide bar. And a screw hole is vertically threaded through and assembled on the moving slide bar. Adjusting screws are vertically rotatably connected to both sides of the top frame. And the adjusting screws are threaded through and assembled in the screw holes of the moving slide bar.

[0007] As a preferred solution, a hole plate is horizontally fixed in the middle of the bottom surface of the sliding frame. And a rod seat is horizontally arranged above the hole plate.

[0008] As a preferred solution, the rod seat is vertically slidably inserted through the hole plate. And a socket is horizontally fixed at one end of the rod seat.

[0009] As a preferred solution, a spring is vertically arranged between the rod seat and the hole plate. And both ends of the spring are respectively fixed on the adjacent end faces of the rod seat and the hole plate.

[0010] As a preferred solution, a damping rod is vertically arranged between the rod seat and the hole plate. And both ends of the damping rod are respectively fixed on the adjacent end faces of the rod seat and the hole plate.

[0011] As a preferred solution, a cable is vertically fixed at the top end of the socket. And the top end of the cable is fixed on the bottom surface of the distribution box.

[0012] As a preferred solution, a screw cylinder is vertically penetrated and fixed in the middle of the moving slide bar. And the screw cylinder is threadedly assembled and connected with the socket.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: During use, the ship shore power plug is inserted into the socket. Then the socket is vertically penetrated and assembled in the middle of the moving slide bar. The adjusting screw on the top frame is rotated, and the threaded drive makes the moving slide bar slide vertically downward on the sliding frame, driving the socket to press against the plug inserted in the socket. Thus, the ship shore power plug is pressed and inserted and assembled on the socket by the socket. Furthermore, the stability of the plug inserted in the socket is ensured. It is avoided that the plug is easily separated from the socket under the gravity of the cable, ensuring the normal charging of the ship and improving the charging efficiency of the ship.
