[0002] The inverter is an electronic device used to control the speed and torque of an AC motor. The inverter driver keyboard is a dedicated input device used to control and manage the inverter driver. The current inverter driver keyboard is fixed to the inverter cabinet through a fixing seat, and the fixing seat is provided with a through hole. The driver keyboard can be detachably installed on the fixing seat. The driver keyboard is connected to the control board of the driver through a network cable with crystal heads (RJ-45 connectors) at both ends. After one end of the network cable passes through the through hole, the crystal head is inserted into the socket of the driver keyboard.

[0003] Since the crystal plug is not fixed to the fixing seat, a longer network cable length needs to be reserved inside the driver so that when the driver keyboard is removed from the fixing seat, the network cable and the crystal plug connected to the driver keyboard can be unplugged together, so that the crystal plug can be plugged into and unplugged from the socket. However, the reserved network cable increases the wiring difficulty in the inverter cabinet and increases the production cost. After the driver keyboard is removed from the fixing seat, the plug needs to be manually unplugged from the socket, and before installing the driver keyboard, the plug needs to be inserted into the socket, which is a cumbersome operation.

[0032] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0033] See also Figure 1-4The fixing seat 100 includes a seat body 1 and a first hook 2. The seat body 1 is provided with a slot 111, and the slot 111 is used for inserting one end of the plug 301 connected to the cable 302 into the seat body 1. The bottom of the slot 111 is provided with a connecting hole 1111 for the cable 302 to pass through. The end of the plug 301 away from the cable 302 extends out of the slot 111 and is used to be plugged into the socket 201. The first hook 2 is connected to the seat body 1, and the first hook 2 is used to be plugged into the groove 3011 on the outer wall of the plug 301.

[0034] In some embodiments, the first hook 2 includes a connecting arm 21 and a hook head 22, one end of the connecting arm 21 is connected to the seat body 1, and the other end of the connecting arm 21 is suspended and connected to the hook head 22, and the hook head 22 is used to cooperate with the groove 3011 on the outer wall of the plug 301 to position the plug 301 on the seat body 1. When the plug 301 is positioned on the seat body 1, the end of the plug 301 away from the cable 302 extends out of the notch of the slot 111.

[0035] In the embodiment of the present application, when the plug 301 is plugged into the slot 111, the hook 22 and the groove 3011 on the outer wall of the plug 301 cooperate to position the plug 301 in the seat body 1, and the portion of the plug 301 exposed from the slot 111 can be plugged into the socket 201 of the driver keyboard 200, and the limiting effect of the first hook 2 on the plug 301 can prevent the plug 301 from being pulled out of the slot 111 when the driver keyboard 200 is removed from the fixing seat 100. Compared with the fixing seat of the traditional driver keyboard, the reserved network cable length can be reduced, the wiring difficulty and production cost in the inverter cabinet are reduced, and the convenience of the driver keyboard 200 during disassembly and assembly is improved.

[0036] In some embodiments, the inner wall of the slot 111 is provided with a notch 1112, the hook 22 is at least partially located in the slot 111, and the connecting arm 21 is used to generate elastic deformation driven by the plug 301 when the plug 301 is inserted into the slot 3011 so that the hook 22 leaves the slot 3011 and enters the notch 1112. When the plug 301 is installed in the slot 111, the end of the plug 301 connected to the cable 302 is inserted into the slot 111, and the cable 302 passes through the seat body 1 through the connecting hole 1111 for connection with other devices. When the end of the plug 301 connected to the cable 302 moves along the notch of the slot 111 toward the bottom of the slot 111, the plug 301 pushes the hook 22, so that the connecting arm 21 is subjected to elastic deformation, and the hook 22 leaves the slot 111 in a direction away from the slot 111 to avoid the plug 301, until the plug 301 moves to align with the groove 3011 and the hook 22, and the hook 22 enters the groove 3011 under the action of the connecting arm 21, so that the hook 22 is engaged in the groove 3011. The end of the plug 301 for plugging with the socket 201 protrudes from the slot 111 through the notch of the slot 111, so that it can be plugged into the socket 201 of the device installed on the fixing base 100. The hook head 22 is snapped into the groove 3011 of the plug 301, and the hook head 22 cooperates with the inner wall of the groove 3011 to limit the plug 301, so as to prevent the device from escaping from the slot 111 with the plug 301 when the device is removed from the fixing base 100, and to prevent the plug 301 from being separated from the socket 201 of the device when the device is removed from the fixing base 100.

[0037] It is worth mentioning that please refer to Figure 5-7 At present, the drive keyboard 200 of the frequency converter is connected to the control board through the cable 302. Both ends of the cable 302 are usually provided with a crystal head (RJ-45 connector). The crystal head is a standard part using industry standards. The main body 3012 of the crystal head is generally in the shape of a rectangular parallelepiped. The first end of the main body 3012 is used to be plugged into the socket 201. The second end of the main body 3012 is used to connect with the cable 302. One of the side walls of the main body 3012 is provided with a step protrusion 3013 near the second end of the main body 3012. The step protrusion 3013 is generally in the shape of a rectangular parallelepiped. The width of the step protrusion 3013 is the same as that of the main body 3012. A groove 3011 is provided at one end of the step protrusion 3013 facing away from the main body 3012. The standard part is also provided with a spring piece A, which is used to clamp the crystal head to the socket 201. When in use, the spring piece A needs to be pressed to pull the crystal head out of the socket 201. In order to facilitate the separation of the crystal plug from the socket 201 , in the embodiment of the present application, the remaining portion after removing the spring piece A from the crystal plug standard part can be used as the plug 301 .

[0038] In some embodiments, the method of removing the spring piece A of the crystal head includes but is not limited to cutting by equipment, breaking and removing by hand, etc.

[0039] It is understandable that the fixing base 100 of the embodiment of the present application is not limited to being used to fix the aforementioned crystal plug without the spring A.
