Description

Technical Field

[0001] The utility model relates to the technical field of converters, in particular to a magnetic flux converter with a plug-in terminal structure. Background Art

[0002] With the continuous development of low-voltage electrical appliance technology, intelligent low-voltage electrical appliances emerge in an endless stream. Generally, the detection mechanism of such intelligent electrical appliances is completed by an electronic circuit and a signal acquisition element, while the actuator is completed by an operating mechanism or an operating device. In this case, a signal transmission connection is required between the detection mechanism and the operating mechanism. At this time, a magnetic flux converter device is needed to complete the connection. The magnetic flux converter mainly uses the principle of electromagnetic induction. When an abnormal situation occurs in the molded case circuit breaker, according to the instructions of the intelligent control system, the magnetic flux converter triggers the corresponding mechanism to perform the tripping operation of the molded case circuit breaker. Therefore, the magnetic flux converter is an important hub device in low-voltage electrical appliances, and its structure, control method, technical performance, etc. directly affect the structural design and performance of the switch.

[0003] The existing patent (publication number: CN215527662U) discloses a magnetic flux converter with plug-in terminals, including a magnetic flux converter main body, a bottom plate, an outer sleeve, a force adjustment ring and a stop block. The bottom end of the magnetic flux converter main body is installed with a bottom plate, and one side of the bottom end of the bottom plate is fixed with an outer sleeve. The outer surface of the outer sleeve is provided with an external thread groove, and the force adjustment ring is installed on the surface of the external thread groove. A movable rod is slidably installed inside the outer sleeve, and a clamping plate is fixed to the bottom end of the movable rod. A limiting spring is installed on the top end of the clamping plate, and the diameter of the limiting spring is larger than the diameter of the outer sleeve. Plug connectors are installed on both sides of the top end of the bottom plate, and anti-fooling heads are provided on the outer walls of the plug connectors. The utility model not only facilitates the installation work of the magnetic flux converter by the staff, can cooperate with actuators of different specifications, and improves the working application range of the magnetic flux converter. The inventor found the following problems in the process of implementing the present utility model: 1. After adjusting the driving force between the moving iron core and the executing component of the existing magnetic flux converter, the force adjustment ring cannot be fixed. Since the force adjustment ring and the outer sleeve are set to be threadedly connected, the force adjustment ring will loosen to a certain extent after the magnetic flux converter is used for a long time, resulting in the movement of the position of the force adjustment ring, thereby reducing the driving force of the moving iron core on the executing component, and further greatly increasing the working error rate of the magnetic flux converter and reducing the working accuracy of the magnetic flux converter; 2. When it is necessary to move the force adjustment ring, it is necessary to first release the fixation of the force adjustment ring. When the traditional force adjustment ring is released from fixation, it needs to be manually twisted and rotated, and the operation process is relatively cumbersome, thus greatly reducing the convenience of the force adjustment ring during movement.

Outside the bottom ends of the two fixing blocks 19, there is a return spring 21.

[0022] In this embodiment, as Figure 1 shown, the housing assembly 1 includes a magnetic flux converter main body 101. In the middle of the top end of the magnetic flux converter main body 101, there is a sleeve 102. Inside the sleeve 102, there is a sliding rod 103. Outside the sleeve 102, there is a pushing block 104. Outside the top end of the pushing block 104, there is a positioning spring 105.

[0023] In this embodiment, as Figure 1 shown, the sleeve 102 and the pushing block 104 are set to be slidably connected; realizing the adjustment of the elastic force of the moving iron core, so as to cooperate with actuators of different specifications, and improving the working application range of the magnetic flux converter.

[0024] In this embodiment, as Figure 3 shown, the internal dimension of the chute 6 is consistent with the external dimension of the slider 10; increasing the stability of the pressing block 7 during movement, and avoiding the situation of inclination and dislocation of the pressing block 7 during movement.

[0028] Usage method and advantages of the present utility model: When the flux converter with a plug-in terminal structure is in use, the working process is as follows:

[0029] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first install the flux converter body 101 at the specified position. When the elastic force of the moving iron core needs to be adjusted, push the push block 104 to move outside the sleeve 102. At this time, the push block 104 drives the two guide blocks 4 to move synchronously under the limit of the guide rod 2. At this time, the push block 104 compresses the positioning spring 105 at the same time to adjust the elastic force of the moving iron core, so that it can be matched with actuators of different specifications to improve the working application range of the flux converter. After the elastic force adjustment of the moving iron core is completed, press Two pressing blocks 7 drive the clamping rod 8 to move to one side of the interior of the first cavity 5 under the cooperation of the slider 10 and the slide groove 6. At this time, the pressing block 7 compresses the spring 9 until the clamping rod 8 is engaged with the interior of the positioning groove 3. When the pressing block 7 moves, the pressing block 7 drives the clamping pin 14 to move synchronously. When the clamping pin 14 moves to the second cavity 15, the compression spring 12 uses its own elastic structure to drive the clamping pin 14 to engage with the interior of the second cavity 15 through the extrusion block 13, so that a clamping structure is formed between the clamping pin 14 and the second cavity 15. The adjusted push block 104 is quickly fixed, which greatly increases the stability of the push block 104 during the fixing period, solves the problem that the push block 104 becomes loose during long-term use, thereby reducing the driving force of the moving iron core on the actuator, thereby reducing the working error rate of the flux converter and greatly increasing the working accuracy of the flux converter. When it is necessary to adjust the elastic force of the moving iron core again, the fixed block 19 is pressed, and the fixed block 19 drives the stop block 18 to push the bayonet 14 through the connecting rod 17 under the cooperation of the limit groove 16 and the moving block 20, so that The locking structure between the locking pin 14 and the second cavity 15 is released. At this time, the fixing block 19 compresses the reset spring 21. After the locking structure between the locking pin 14 and the second cavity 15 is released, the pressing block 7 drives the locking rod 8 to disengage from the interior of the positioning groove 3 under the elastic structure of the spring 9, thereby quickly releasing the fixing structure between the guide block 4 and the guide rod 2, reducing the difficulty of operation, and greatly improving the convenience of the push block 104 when releasing the fixation, thereby meeting the requirements of the flux converter of the plug-in terminal structure, and further realizing the readjustment of the elastic force of the moving iron core.
