[0002] The transformer is one of the main equipment in power plants and substations. The transformer can meet the needs of electricity consumption, and the transformer needs to be connected to the power cable when in use. Usually, a transformer needs to be connected to multiple cables, so a power connector is used for connection. There are at least the following disadvantages in the use of existing power connectors: 1. Since the connector at the transformer docking point and the cable connector are both round and there is no difference, when moving the transformer or repairing the transformer, the cable needs to be unplugged and then plugged back in. In this case, the power connector may be connected incorrectly. If the docking is wrong, it may cause dangers such as short circuits, posing a safety hazard; 2. When the two existing power connectors are connected, when the two power connectors are vibrated, the connection is prone to loosening and falling off, affecting the connection effect of the power connector and reducing practicality. Therefore, we introduce a power connector anti-wrong connection structure. Utility Model Content

[0022] See also Figure 1-4 , the utility model provides a technical solution:
[0023] A power connector misconnection prevention structure comprises a female connector 1 and a male connector 2, wherein the lower left and lower right portions of the male connector 2 are fixedly connected with misconnection prevention mechanisms 3, a first power cord 4 is installed in the middle of the right end of the male connector 2, the upper right and lower right portions of the female connector 1 are fixedly connected with docking mechanisms 5, the middle portions of opposite surfaces of the two docking mechanisms 5 are fixedly connected with reinforcement mechanisms 6, a second power cord 7 is installed in the middle of the left end of the female connector 1, and the left portion of the outer surface of the male connector 2 is clamped with the middle of the right end of the female connector 1.
[0024] In this embodiment, the error-proof mechanism 3 includes an error-proof block 31. A first fixing groove 32 is formed in the middle of the lower end of the error-proof block 31, and the groove wall of the first fixing groove 32 is fixedly connected to the outer surface of the male connector 2. An error-proof frame 33 is fixedly connected through the middle of the left end of the error-proof block 31, and two positioning holes 34 are formed in the upper left part of the error-proof frame 33. The docking mechanism 5 includes a docking block 51. A second fixing groove 52 is formed in the middle of the lower end of the docking block 51, and the groove wall of the second fixing groove 52 is fixedly connected to the outer surface of the female connector 1. A docking groove 53 is formed in the middle of the right end of the docking block 51, and two reinforcing holes 54 are formed in both the upper groove wall and the lower groove wall of the docking groove 53. Both the docking groove 53 and the error-proof frame 33 are of I-shaped structures, so that the docking groove 53 is firmly clamped with the error-proof frame 33, and the shapes of both the docking groove 53 and the error-proof frame 33 can be changed into matching special-shaped shapes, which can realize error-proof docking of different power connectors. The distance between the two positioning holes 34 is the same as the distance between the two upper reinforcing holes 54, which is beneficial to the accurate insertion of the reinforcing frame 64.
[0025] In this embodiment, the reinforcing mechanism 6 includes a storage box 61. Through openings 62 are formed in both the left part and the right part of the lower box wall of the storage box 61. A screw rod 63 is threadedly connected to the middle of the upper box wall of the storage box 61. The lower end of the screw rod 63 is inserted and movably connected through a bearing with a reinforcing frame 64. The upper end of the screw rod 63 is fixedly connected with a handle 65. The lower end of the storage box 61 is fixedly connected to the upper end of the upper docking block 51. The two through openings 62 are respectively located directly above the corresponding two reinforcing holes 54. The reinforcing frame 64 is of a C-shaped structure, which is convenient for the screw rod 63 to adjust the position of the reinforcing frame 64, and is also convenient for inserting the reinforcing frame 64 into the corresponding reinforcing holes 54 and positioning holes 34, so that the error-proof frame 33 is firmly connected to the docking block 51.
[0026] It should be noted that the utility model is a power connector anti-misconnection structure. During use, the male connector 2 is first inserted into the female connector 1. At this time, the anti-misconnection frame 33 is also inserted into the corresponding docking groove 53. When the anti-misconnection frame 33 matches the docking groove 53, the male connector 2 and the anti-misconnection frame 33 can be inserted, otherwise they cannot be inserted. Moreover, the shapes of the anti-misconnection frame 33 and the docking groove 53 on each pair of power connectors are different, so only two power connectors of corresponding shapes can be connected together, so that after the user removes the male connector 2 and the female connector 1, they can be quickly and correctly re-docked together when they need to be installed again, which can prevent the male connector 2 from being connected to the female connector 1, thereby avoiding power outages. The power connector can be prevented from short-circuiting or other dangerous situations due to incorrect docking, thereby improving safety. When the female connector 1 and the male connector 2 are connected, the handle 65 can be rotated to drive the screw 63 to rotate, so that the reinforcement frame 64 can move downward stably under the guide limit of the storage box 61, and the two side rods on the reinforcement frame 64 can pass through the two through openings 62 respectively, and then pass through the upper reinforcement hole 54 and the positioning hole 34 in turn and be inserted into the lower reinforcement hole 54, so that the anti-mistake frame 33 and the docking block 51 can be firmly fixed, thereby strengthening the firmness of the connection between the female connector 1 and the male connector 2, and preventing the female connector 1 and the male connector 2 from loosening and falling off due to vibration, thereby strengthening the connection effect of the power connector and improving the practicality of the power connector.
