DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, an embodiment of the present application discloses a pluggable circuit breaker controller, including a controller and a circuit breaker actuator;

[0025] The controller comprises a first housing 1, a first control module is arranged in the first housing 1, a first electrical connector 2 is arranged on the first control module, and a plurality of first through holes 3 are arranged on the surface of the first housing 1;

[0026] The circuit breaker actuator includes a second housing 4, a second control module is arranged in the second housing 4, a second electrical connector 5 matching the first electrical connector 2 is arranged on the second control module, a plurality of plug-in columns 6 are fixedly connected in the second housing 4, a through hole is arranged inside the plug-in column 6, and the positions of the plurality of through holes correspond to the plurality of first through holes 3 one by one, a mounting nut 7 is arranged at the lower end of the through hole, and an internal thread structure is arranged inside the mounting nut 7;

[0027] It also includes a connecting screw 8, the lower end of which is provided with an external thread structure that matches the internal thread structure;

[0028] The connecting screw 8 is used to pass through the first through hole 3 and the through hole and be threadedly connected with the mounting nut 7. When the controller and the circuit breaker actuator are installed in position, the first electrical connector 2 and the second electrical connector 5 are plugged in.

[0029] Specifically, in this embodiment, the second electrical connector 5 is a 90-degree bent socket, and the socket end of the 90-degree bent socket is arranged toward the controller;

[0030] The first electrical connector 2 is a pin structure, and the pin of the pin structure is arranged toward the socket end of the 90-degree bent socket.

[0031] Specifically, when the controller and the circuit breaker actuator need to be connected, the connecting screw 8 is inserted into the first through hole 3, and then the connecting screw 8 is inserted into the through hole. When the multiple screws on the controller are inserted into the through hole, it means that the controller and the circuit breaker actuator have been aligned. At this time, the controller and the circuit breaker actuator are pressed, and the first electrical connector 2 can complete the connection with the second electrical connector 5. Combined with the rotating connecting screw 8, the connecting screw 8 can be threadedly connected with the mounting nut 7 in the through hole to achieve a fixed connection between the controller and the circuit breaker actuator. When the controller and the circuit breaker actuator need to be disassembled, just rotate the connecting screw 8, pull the connecting screw 8 out of the through hole, and then pull the controller upward.

[0032] This structure adopts a fixing method in which the connecting screw 8, the through hole and the mounting nut 7 cooperate with each other, so that the controller and the circuit breaker actuator can be quickly disassembled and assembled without the need for special tools, saving time and effort, thereby improving work efficiency.

[0033] In this embodiment, a flange 801 is provided at the top end of the connecting screw 8 .

[0034] Specifically, when the bottom of the connecting screw 8 and the mounting nut 7 are completely screwed into place, the lower surface of the flange 801 can contact the surface of the controller.

[0035] The setting of the flange 801 in this structure can serve as a prompt for whether the connecting screw 8 is tightened in place. When the lower surface of the flange 801 does not contact the surface of the controller, it means that the connecting screw 8 is not tightened in place at this time, and the connecting screw 8 can continue to rotate. When the lower surface of the flange 801 contacts the surface of the controller, it means that the connecting screw 8 is tightened in place at this time, and the connecting screw 8 does not need to continue to rotate, thereby ensuring the connection stability of the controller and the circuit breaker actuator.

[0036] In this embodiment, a tapered surface 601 is provided at the opening of the through hole of the plug-in column 6 , and the diameter of the upper end of the tapered surface 601 is greater than the diameter of the lower end.

[0037] When the controller and the circuit breaker actuator need to be installed, the connecting screw 8 needs to be inserted into the through hole. Since a tapered surface 601 is provided at the opening of the through hole, even if the connecting screw 8 is not accurately aligned with the through hole at the beginning, if the end face of the connecting screw 8 contacts the tapered surface 601, the connecting screw 8 can slide into the through hole under the guidance of the tapered surface 601, so that the connecting screw 8 can be inserted into the through hole without precise alignment, thereby improving the convenience of installation.

[0038] In this embodiment, two first through holes 3 are provided, and the two first through holes 3 are respectively located at diagonally opposite positions on the surface of the first shell 1 .

[0039] Specifically, a plurality of first through holes 3 can be provided. In the present embodiment, two are provided at diagonal positions. This arrangement at diagonals can realize the positioning of the X-axis and Y-axis of the controller by using only two connecting screws 8. At the same time, during the specific installation, only the assembly of the two connecting screws 8 needs to be completed.

[0040] In this embodiment, a clamping spring 9 sleeved on the connecting screw 8 is further included, and the clamping spring 9 is used to connect the connecting screw with the first housing 1 .

[0041] Specifically, the retaining spring in the present structure can be used to realize axial connection between the connecting screw and the first housing, so that during each installation process, there is no need to reinsert the connecting screw into the first through hole each time. It is only necessary to insert the connecting screw into the through hole of the second housing to complete the alignment, and then tighten the connecting screw, thereby facilitating the installation of the controller and the circuit breaker actuator. At the same time, when disassembling, it is only necessary to rotate the connecting screw. After the connecting screw exits the threaded part, the first electrical connector 2 can be pulled out of the second electrical connector 5 by pulling the connecting screw.

[0042] In this embodiment, a liquid crystal display screen 10 is further provided on the surface of the first housing 1 , and the liquid crystal display screen 10 is signal-connected to the first control module.

[0043] In the device, the design of the liquid crystal display screen 10 can realize the display of data such as the measured voltage, thereby making the device more convenient to use.

[0044] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
