This makes shipping and on-site installation of separate cabinets extremely inconvenient. The main inconvenience lies in the need to first disconnect the control cables from the high-voltage frequency converter unit inside the cabinet, then separate the control cables from the cabinet to separate the cabinets that were originally connected by control signals. Furthermore, when needed, the control cables must be routed through the side wall of the cabinet and into the interior to connect to the high-voltage frequency converter unit located within. Therefore, a connector for electrical control cabinets and an electrical control cabinet equipped with such a connector are required. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by providing a first and second connection terminal on both the male and female connectors. This allows for electrical connection through the first and second connection terminals penetrating the side wall of the cabinet. When it is necessary to electrically connect the high-voltage frequency converter units located in the two cabinets, it is only necessary to insert the male and female connectors between the two cabinets into the sockets. To separate the two cabinets, the control line can be physically cut by simply pulling the male connector out of the female connector. This solves the problems of inconvenience in separating the cabinets of current high-voltage frequency converters and inconvenience in on-site installation.

[0018] like Figure 1-4 As shown, a terminal connector for control line connection includes a male connector 1 and a female connector 2. The male connector 1 has a plug 15 and a first connecting end 4, the plug 15 being electrically connected to the first connecting end 4. The female connector 2 has a socket 3 and a second connecting end 16, the socket 3 being electrically connected to the second connecting end 16. The plug 15 is electrically engaged with the socket 3. The side wall of the plug 15 has an elastic post 5, and the inner wall of the socket 3 has a groove 6 that engages with the elastic post 5. The side wall of the female connector 2 has a through hole 7, one end of each through hole 7 corresponding to the bottom of a groove 6 and communicating with the groove 6. The female connector 2 has a compression post 8 provided by an elastic element, one end of the compression post 8 extending into the through hole 7, and the length of the compression post 8 being greater than the sum of the length of the through hole 7 and the length of the groove 6.

[0019] In this embodiment, during use, for example, the two ends of a batch of first connecting terminals 4 and / or the two ends of second connecting terminals 16 are passed through a wiring hole on the side wall of a cabinet 14. At this time, both the male connector 1 and / or the female connector 2 are located outside the cabinet 14. Then, the free ends of the first connecting terminals 4 and the free ends of the second connecting terminals 16 are electrically connected to the high-voltage frequency converter unit inside the cabinet 14. Then, the wiring hole on the side wall of another cabinet 14 is also passed through the two ends of another batch of first connecting terminals 4 and / or the two ends of second connecting terminals 16. Similarly, the first connecting terminals 4 and / or the female connector 2 inside the cabinet 14 are connected to the high-voltage frequency converter unit inside the cabinet 14. A connecting end 4 and a second connecting end 16 are also electrically connected to the high-voltage frequency converter unit located inside the cabinet 14. At this time, the male connector 1 and / or the female connector 2 are both located outside the cabinet 14. When connecting two cabinets 14, the plug 15 of the male connector 1 on the outer wall of one cabinet 14 is inserted into the socket 3 of the female connector 2 on the other cabinet 14 to achieve connection. After the plug 15 of the male connector 1 is inserted into the socket 2 of the female connector 2, the elastic post 5 on the plug 15 extends into the groove 6 on the inner wall of the socket 3, preventing the plug 15 from falling out of the socket 3. When it is necessary to separate the two cabinets 14, by pressing and squeezing the post 8, the elastic post 5 is retracted into the plug 15. At this time, the elastic post 5 disengages from the groove 6, and then the plug 15 can be pulled out of the socket 3. When the elastic element is compressed, the compression post 8 needs to be able to press the elastic post 5 into the plug 15, so the length of the compression post 8 is greater than the sum of the length of the through hole 7 and the length of the groove 6. When the elastic element returns to its original state, the end of the compression post 5 facing the groove 6 exits from the groove 6 and retracts into the through hole 7.

[0020] As a preferred embodiment, the sidewall of the elastic post 5 facing the free end of the plug 15 is a slope 9. The distance from the end of the slope 9 opposite to the plug 15 to the root of the plug is less than the distance from the end of the slope 9 facing the plug 15 to the root of the plug 15. By setting the slope 9, when the plug 15 is inserted into the socket 3, the edge of the socket 3 presses against the slope 9, squeezing the elastic post 5 into the plug 15, allowing the plug 15 to be inserted into the socket 3. The side of the elastic post 5 facing away from the free end of the plug 15 is a flat surface, so that after the plug 15 is inserted into the socket 3, it is blocked by the sidewall of the groove 6 facing the plug 15, thereby preventing the plug 15 from falling out of the socket.

[0021] In a preferred embodiment, the outer wall of the female head 2 is provided with an expansion groove 10. The projection of the groove 6 onto the bottom wall of the expansion groove 10 is surrounded by the bottom wall of the expansion groove 10. The through hole 7 penetrates the bottom walls of the expansion groove 10 and the groove 6, connecting the expansion groove 10 and the groove 6. A pressing plate 11 is provided inside the expansion groove 10. The shape and size of the pressing plate 11 are equal to the shape and size of the bottom wall of the expansion groove 10. One end of the extrusion post 8 is located inside the expansion groove, and the other end is located inside the through hole 7. The end of the extrusion post 8 located inside the expansion groove 10 is fixedly connected to the pressing plate 11. One end of the elastic element is fixedly connected to the bottom of the expansion groove 10, and the other end is fixedly connected to the pressing plate 11. After the expansion groove 10 is provided, it is used to install the pressing plate 11, which facilitates pressing.

[0022] As a preferred embodiment, the pressing plate 11 is sealed to the outer wall of the expansion groove 10 on the female head 2 via insulating elastic rubber 12. The insulating elastic rubber 12 prevents impurities from entering the expansion groove 10.

[0023] As a preferred embodiment, the elastic element is a spring 13.

[0024] The female head 2 has a side plate 17 on its side wall, which becomes one end face of the groove 6, thus facilitating the machining of the groove 6.

[0025] like Figure 4 As shown, an electrical control cabinet includes a cabinet body 14. The outer side wall of the cabinet body 14 is provided with a plurality of the aforementioned female connectors 2 and male connectors 1. The first connection end 4 of each male connector 1 and the second connection end 16 of each female connector 2 on the outer side wall of the cabinet body 14 extend through into the cabinet body 14.
