Among them, shore power connectors are the key connecting components between ships and onshore power systems. The application of shore power connectors not only helps to enhance the environmental image of ports, but also provides ships with more convenient and efficient power services.

[0003] The actual shore power connector device is mainly composed of a male head plugged into a female head. However, when the male head is plugged into the female head, a locking structure needs to be set to ensure the connection stability between the male head and the female head. When the two are plugged together, the operation is difficult and the connection time is long. The operation is difficult and requires professional training for operators. For this reason, technical personnel in this field have proposed a lock-free shore power quick connector device to solve the problems raised by the background technology.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention provides an anti-loosening spring ring. When the male connector end is inserted into the disassembly connector, the anti-loosening spring ring is pressed by the clamping force of the clamping teeth on the anti-loosening spring ring to ensure that the anti-loosening spring ring is clamped at the interface of the male connector end after the male connector is inserted and cannot be pulled out, thereby enhancing the firmness of the plug-in connection. By pressing the quick-release wrench, the quick-release wrench squeezes the disassembly buckle through the convex ring, and the disassembly buckle moves upward in the disassembly connector to squeeze the clamping teeth. The slope at the front end of the disassembly buckle will open the anti-loosening spring ring, canceling the fixation of the anti-loosening spring ring on the interface of the male connector end, so that the male connector can be quickly plugged into the female connector without the need for additional locking operation, thereby greatly shortening the connection time. The quick plug-in method allows operators to easily master the quick plug-in skills without professional training, thereby reducing the difficulty of operation.

[0019] 2. The present invention uses the positioning flange on the male head to fix the position of the male head when plugging into the female head to prevent wrong phase sequence connection, and a silicone sealing gasket is provided on the top of the plug-in boss to ensure the water tightness of the joint.

[0020] 3. The present invention provides an anti-disconnection hook on the quick-release wrench so that the end of the anti-disconnection hook is connected to the limiting groove provided on the limiting block, and the tension of the tension spring is used to keep the quick-release wrench at a certain opening angle on the disassembly joint to prevent misoperation. The anti-disconnection hook limits the degree of freedom of the quick-release wrench to ensure smooth insertion of the male head.

[0021] 4. The present invention provides an opening at the end of the terminal and a retaining spring disposed in the opening, so that the terminal post fits tightly when plugged into the terminal, ensuring that there is no loose connection between the male and female heads when plugged together, and the setting of the groove at the end of the terminal effectively ensures the smooth plugging of the terminal post.

A U-shaped silicone pad is provided at the top of the male connector 2 to ensure the watertightness of the connector. The male connector 2 is installed on the power receiving device at the ship end to connect the power receiving device at the ship end with the shore power system, thereby receiving the shore power supply. Through the terminal 21, power can be transmitted from the male connector 2 to the female connector 1 from the wire or cable. The terminal 21 is provided in multiple and evenly distributed in a circle. The fixing buckle 24 is used to fix the wire or cable in the male connector 2;

[0038] The plug-in assembly 3 is arranged in the disassembly joint 12. The plug-in assembly 3 includes an anti-loosening spring coil 31 arranged in the disassembly joint 12. A disassembly buckle 32 is arranged in the disassembly joint 12. The anti-loosening spring coil 31 and the disassembly buckle 32 are both sleeved on the outside of the joint end of the male head 2. A quick-release wrench 34 is arranged on the bottom edge of the disassembly joint 12. The quick-release wrench 34 is close to the disassembly buckle 32. The anti-loosening spring coil 31 is used to clamp the outside of the joint end of the male head 2. A sloped mouth 53 is arranged at the end of the disassembly buckle 32. The disassembly buckle 32 is used to open the anti-loosening spring coil 31. The quick-release wrench 34 is used to squeeze the disassembly buckle 32.

[0039] Specifically, a fixed base 111 is fixedly connected to the terminal end 11, a first locking nut 112 is arranged on the top of the terminal end 11, a plurality of fixing screws 22 are arranged on the male head 2, an inner core fixing frame 23 is arranged inside the male head 2, the plurality of fixing screws 22 are all threadedly connected to the inner core fixing frame 23, a second locking nut 25 is arranged at the bottom of the male head 2, a plurality of bolts are arranged on the fixed base 111, which are used to fix the entire device in the shore power box, the first locking nut 112 is used to lock the wires or cables connected to the shore power box on the female head 1, the fixing screws 22 are threadedly connected to the inner core fixing frame 23 so that the male head 2 can be disassembled and assembled, and the second locking nut 25 is used to lock the wires or cables on the ship connected to the male head 2.

[0040] Furthermore, a latch tooth 311 is provided on the anti-loosening spring coil 31, a connecting seat 33 is fixedly connected to the disassembly joint 12, a convex ring 35 is provided on the top of the quick release wrench 34, the latch tooth 311 is elastic on the anti-loosening spring coil 31, and is obliquely arranged on the anti-loosening spring coil 31, the connecting seat 33 is used to receive the quick release wrench 34, and the convex ring 35 is used to squeeze the disassembly buckle 32 so that the disassembly buckle 32 moves upward in the disassembly joint 12.

[0041] Furthermore, a plurality of latch teeth 311 are evenly distributed in a tapered circle to squeeze and fix the outside of the connector end of the male connector 2 . The quick-release wrench 34 is hinged on the connecting seat 33 , and the convex ring 35 is attached to the bottom of the disassembly buckle 32 .

[0042] As can be seen from the above, the anti-loose spring ring 31 is provided. When the connector end of the male connector 2 is inserted into the disassembly connector 12, under the extrusion force of the multiple locking teeth 311 on the anti-loose spring ring 31, it is ensured that the anti-loose spring ring 31 is stuck at the connector end interface of the male connector 2 after the male connector 2 is inserted, and cannot be pulled out, that is, the insertion is not loose, thereby enhancing the firmness of the plug-in connection. Since the quick-release wrench 34 is hinged to the bottom edge of the disassembly connector 12 through the connecting seat 33, by pressing the quick-release wrench 34, the quick-release wrench 34 squeezes the disassembly buckle 32 through the convex ring 35 provided thereon.
