In the interconnection of electronic circuits, multiple connectors of the same specification are often installed on the same panel or PCB. To prevent the mis-mating of connectors, connectors are generally required to have an anti-mating function. To ensure that the connectors can be locked and anti-mating, existing rectangular electrical connectors typically have separate locking and anti-mating structures designed into the connector structure. This design leads to complex structures, large size, high production costs, and inconvenient disassembly and maintenance. Utility Model Content

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, a rectangular electrical connector locking structure provided by an embodiment of the present invention includes an upper connector 1 and a lower connector 2, the bottom of the upper connector 1 is fixedly connected to a snap ring 3, the top of the lower connector 2 is fixedly connected to a clamping block 4, the clamping block 4 is used in conjunction with the snap ring 3, the top of the upper connector 1 is threadedly connected to two threaded columns 5, the top of the lower connector 2 is fixedly connected to a connecting block 6, the threaded column 5 is threadedly connected to the connecting block 6, one side of the connecting block 6 is movably connected to a pulling column 7, the side of the pulling column 7 close to the connecting block 6 is fixedly connected to a connecting column 8, the surface of the connecting column 8 is sleeved with a spring 9, the side of the connecting column 8 away from the pulling column 7 is fixedly connected to a connecting plate 10, the side of the connecting plate 10 away from the connecting column 8 is fixedly connected to a clamping column 11, and the surface of the threaded column 5 is provided with a clamping groove 12 for use with the clamping column 11.

[0022] refer to Figure 4 The top and bottom of the connecting plate 10 are fixedly connected to the limit slider 13, and the inner wall of the connecting block 6 is provided with a limit slot 14 used in conjunction with the limit slider 13.

[0023] The above solution is adopted: by setting the limiting slider 13 and the limiting groove 14, the connecting plate 10 can be made to move more easily with the connecting column 8, and the connecting plate 10 is horizontally limited, which reduces the wear of the connecting plate 10, extends the service life of the connecting plate 10, and avoids affecting the movement of the connecting plate 10.

[0024] refer to Figure 4 The inner wall of the connecting block 6 is provided with an auxiliary groove 15 , which is used in conjunction with the connecting column 8 , the connecting plate 10 and the spring 9 .

[0025] By adopting the above solution: by setting the auxiliary groove 15, the connecting plate 10, the spring 9 and the connecting column 8 can have space for movement, reducing the wear of the connecting plate 10, the spring 9 and the connecting column 8, and extending the service life of the connecting plate 10, the spring 9 and the connecting column 8.

[0026] The working principle of this utility model:

[0027] During use, the user makes the clamping ring 3 of the upper connector 1 of the rectangular electrical connector fit and clamp with the clamping block 4 of the lower connector 2 of the rectangular electrical connector, and then the user pulls the pulling column 7, and the pulling column 7 drives the connecting column 8 to move, and the connecting column 8 drives the connecting plate 10 to move, thereby squeezing the spring 9, and then the user rotates the threaded column 5 to make the threaded column 5 and the connecting block 6 be threadedly connected. When the threaded column 5 cannot be rotated, the clamping groove 12 of the threaded column 5 is in a line with the clamping block 4, and the user loosens the pulling column 7 to make the clamping column 11 clamp into the clamping groove 12 on the threaded column 5, thereby limiting the threaded column 5 and locking the rectangular electrical connector.

[0028] To sum up: the rectangular electrical connector locking structure solves the problems of the existing rectangular electrical connector that the locking structure and the anti-wrong insertion structure must be designed separately in the connector structure, and the connector products designed in this way have the problems of complex structure, large size, high production cost, inconvenient disassembly and maintenance, by setting the upper connector 1, the lower connector 2, the snap ring 3, the clamping block 4, the threaded column 5, the connecting block 6, the pulling column 7, the connecting column 8, the spring 9, the connecting plate 10, the clamping column 11, the clamping groove 12, the limiting slider 13, the limiting slide groove 14 and the auxiliary groove 15.
