Description

Technical Field

[0001] This utility model belongs to the field of electrical component installation technology, specifically relating to an electromagnet installation structure. Background Technology

[0002] In the electrical field, the electric closing and opening of circuit breakers are accomplished by the operation of electromagnets. Specifically, electromagnet closing: after being energized, the electromagnetic force drives the mechanical mechanism to complete the closing (usually requiring a large instantaneous current); electromagnet opening: opening is achieved by releasing the holding mechanism or reversing its action (requiring less current but a fast response). Electrical characteristics, mechanical action requirements, and thermal design limitations jointly determine that circuit breaker closing and opening electromagnets are all short-time duty. Due to factors such as prolonged energization, incorrect control power input (referred to as "power abnormality"), and frequent operation, coil burnout faults can occur from time to time. Furthermore, for circuit breakers that are frequently operated, as mentioned above, timely replacement of the closing and opening electromagnets during operation and maintenance is also of positive significance to ensure reliable operation.

[0003] In existing technologies, electromagnets are typically installed directly with screws or using a pressure plate followed by screws. This installation method is cumbersome due to the limited space inside the circuit breaker housing, sometimes requiring the removal of other interfering components to create space. Furthermore, the removal of certain structural components may require specialized tools, thus affecting the efficiency of replacing the closing and opening solenoid blocks. Therefore, exploring effective technical means to improve the efficiency of disassembling and installing closing and opening electromagnets is of significant importance. Summary of the Invention

The lower end of the positioning pin passes through the through hole on the mounting plate and inserts into the positioning pin upper end insertion hole. The middle part corresponds to the area between the bottom surface of the frame and the mounting plate.

[0017] In order to better understand the technical essence and beneficial effects of this utility model, the applicant provides a detailed description below by way of embodiments. However, the description of the embodiments is not intended to limit the solution of this utility model. Any formal but not substantive equivalent transformations made based on the concept of this utility model should be considered within the scope of the technical solution of this utility model.

[0018] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are currently defined by... Figure 1 The location and state are taken as a reference, and therefore should not be construed as a special limitation on the technical solution provided by this utility model.

[0019] Please see Figure 1 The diagram shows an electromagnet assembly 1 and a mounting plate 2. The electromagnet assembly 1 is located above the mounting plate 2. In use, the mounting plate 2 is fixed inside the circuit breaker housing by fasteners 22 such as screws or rivets, i.e., fixed to the mounting plate bracket inside the circuit breaker housing.

[0020] The key technical point of the present invention is that the electromagnet installation structure of the present invention also includes a quick assembly / disassembly mechanism 3 for electromagnet assembly 1 and the mounting plate 2 that can be connected or disconnected by hand without the aid of tools. The quick assembly / disassembly mechanism 3 is disposed on the electromagnet assembly 1 and is connected to the mounting plate 2 by a push-pull sliding connection.

[0021] Depend on Figure 1 and Figure 2 As shown, the aforementioned electromagnet assembly 1 includes a frame 11, which has a coil cavity 111. The aforementioned electromagnet assembly quick disassembly and assembly mechanism 3, which is in a push-pull sliding connection (or toggle sliding connection) with the aforementioned mounting plate 2, is disposed on the frame 11.

[0022] Please see Figures 2 to 3 And combined Figure 1The aforementioned electromagnet assembly quick-release mechanism 3 includes a positioning pin seat 31, a positioning pin 32, a positioning pin force spring 33, a sliding flange device 34, a sliding flange guide and limit device 35, and a locking member 36. The positioning pin seat 31 is preferably fixed to the bottom wall of the coil cavity 111 of the aforementioned frame 11 by welding and is located at the right end of the front opening of the coil cavity 111. A positioning pin upper end insertion hole 311 is formed at the longitudinal center of the positioning pin seat 31, and the front and rear sides of the wall of the positioning pin seat 31... Furthermore, a locking guide groove 312 is longitudinally formed at each corresponding position. This locking guide groove 312 communicates with the aforementioned upper end insertion hole 311 of the positioning pin. The upper end insertion hole 311 of the positioning pin corresponds to and communicates with the upper end relief hole 1111 of the positioning pin formed on the bottom wall of the coil cavity. The upper end of the positioning pin 32 passes through the upper end relief hole 1111 and enters the aforementioned upper end insertion hole 311 of the positioning pin. The middle part corresponds to the area between the bottom surface of the frame 11 and the aforementioned mounting plate 2, while the lower end of the positioning pin 32... A positioning pin latch hole 21, located on the upper part of the mounting plate 2 and corresponding fully to the aforementioned positioning pin upper end clearance hole 1111, is fitted into the positioning pin latch hole 21. A positioning pin force spring 33 is located within the aforementioned positioning pin upper end insertion hole 311 and is sleeved on the upper end of the positioning pin 32. The upper end of the positioning pin force spring 33 is supported on the insertion hole step 3111 formed on the upper part of the positioning pin upper end insertion hole 311, while the lower end of the positioning pin force spring 33 is supported on the positioning pin step 322 formed on the upper end of the positioning pin 32. The middle part of the locking member 36 passes through the positioning pin locking member hole 321, which is opened in the middle of the height direction of the positioning pin 32 and penetrates the diameter of the positioning pin 32. The front end and the rear end of the locking member 36 protrude from the aforementioned locking member guide sliding relief groove 312 and abut against the positioning pin seat 31. The sliding flange device 34 is provided at the bottom right end of the aforementioned frame 11. The sliding flange device 34 corresponds to and cooperates with the sliding flange guide limiting device 35, which is provided on the upper part of the aforementioned mounting plate 2.

[0023] The aforementioned locating pin force spring 33 is a helical spring.

[0024] In this embodiment, the aforementioned locking member 36 is a cotter pin, and is preferably made of bent spring steel wire.

[0025] The aforementioned sliding flange device 34 includes a first sliding flange 341 and a second sliding flange 342. The first sliding flange 341 and the second sliding flange 342 are positioned at the bottom right end of the aforementioned frame 11, spaced apart laterally and staggered front-to-back, and slide in cooperation with the aforementioned sliding flange guide and limiting device 35. Of course, the positions of the sliding flange device 34 and the sliding flange guide and limiting device 35 can be interchanged, thus representing another variation of the implementation without departing from the scope of the technical content disclosed in this utility model. That is, the sliding flange device 34 can be mounted on the mounting plate 2, and the sliding flange guide and limiting device 35 can be mounted on the frame 11.

[0026] The aforementioned sliding flange guide limiting device 35 includes a first flange guide limiting groove 351 and a second flange guide limiting groove 352. The first flange guide limiting groove 351 and the second flange guide limiting groove 352 are configured on the aforementioned mounting plate 2 in a state of being spaced apart from each other on the left and right and staggered in front and behind each other. The first flange guide limiting groove 351 corresponds to the aforementioned first sliding flange 341 and a first arc-shaped hole 3511 communicating with the first flange guide limiting groove 351 is extended at the right end of the first flange guide limiting groove 351. The second flange guide limiting groove 352 corresponds to the aforementioned second sliding flange 342 and a second arc-shaped hole 3521 is extended at the right end of the second flange guide limiting groove 352. The aforementioned first and second sliding flanges 341 and 342 are respectively slidably engaged with the aforementioned first and second flange guide limiting grooves 351 and 352.

[0027] In the mechanical field, the structural form of the first and second flange guide limiting grooves 351 and 352 mentioned above is often referred to as gourd-shaped holes.

[0028] Depend on Figure 1 As shown, the upper part of the aforementioned first sliding flange 341 is provided with a first neck 3411 with a diameter smaller than that of the first sliding flange 341, and the upper part of the aforementioned second sliding flange 342 is provided with a second neck 3421 with a diameter smaller than that of the second sliding flange 342. The first neck 3411 is slidably engaged with the aforementioned first flange guide limiting groove 351, and the second neck 3421 is slidably engaged with the aforementioned second flange guide limiting groove 352. When the first neck 3411 and the second neck 3421 simultaneously enter the positions of the aforementioned first arc-shaped hole 3511 and the second arc-shaped hole 3521, the aforementioned frame 11 enters a state that is ready to be separated from the aforementioned mounting plate 2. The height of the aforementioned first neck 3411 and the aforementioned second neck 3421 is adapted to the thickness of the aforementioned mounting plate 2.

[0029] Depend on Figure 1 and Figure 2As shown, the aforementioned electromagnet assembly 1 also includes a coil 12, which is horizontally disposed in the aforementioned coil cavity 111. The right end of the iron core 121, which moves left and right in the coil center hole along the axial direction of the coil 12, protrudes from the coil center hole and extends to the right side of the aforementioned frame 11. The aforementioned mounting plate 2 is shaped like a ┐.

[0030] The applicant should clarify that, in this embodiment, the first and second flange guide limiting grooves 351 and 352 of the aforementioned sliding flange guide limiting device 35 are arranged laterally, but they can also be arranged longitudinally. When arranged longitudinally, the first and second sliding flanges 341 and 342 of the aforementioned sliding flange device 34 are also changed accordingly to meet the adaptability requirements of the first and second flange guide limiting grooves 351 and 352. In other words, the lateral arrangement of the first and second flange guide limiting grooves 351 and 352 in this embodiment is merely a non-limiting example and should not be considered as deviating from the scope of the technical connotation defined and disclosed by this utility model due to the change in form.

[0031] Please see Figure 4If the functions of the aforementioned positioning pin latch hole 21 and the positioning pin upper end clearance hole 1111 are interchanged, and the positioning pin seat 31 is installed on the mounting plate 2 at the position corresponding to the positioning pin latch hole 21, then this is another form of implementation that still does not depart from the scope of the technical content disclosed in this utility model. Specifically, the electromagnet assembly 1 includes a frame 11, and the electromagnet assembly quick-release mechanism 3 includes a positioning pin seat 31, a positioning pin 32, a positioning pin force spring 33, a sliding flange device 34, a sliding flange guide and limit device 35, and a locking member 36. The positioning pin seat 31 is fixed on the mounting plate 2. A positioning pin upper end insertion hole 311 is formed at the longitudinal center of the positioning pin seat 31. A locking member guide sliding relief groove 312 is longitudinally formed on the front and rear sides of the wall of the positioning pin seat 31 at corresponding positions. The locking member guide sliding relief groove 312 communicates with the positioning pin upper end insertion hole 311. The positioning pin upper end insertion hole 311 corresponds to and communicates with the through hole on the mounting plate 2. The lower end of the positioning pin 32 passes through the through hole on the mounting plate 2 and enters the positioning pin upper end insertion hole 311. The middle part corresponds to the area between the bottom surface of the frame 11 and the mounting plate 2, and the upper end of the positioning pin 32... The positioning pin 32 is fitted with a clearance hole 1111 on the upper end of the positioning pin 11. The positioning pin force spring 33 is located in the upper end insertion hole 311 of the positioning pin and is sleeved on the upper end of the positioning pin 32. The upper end of the positioning pin force spring 33 is supported on the through hole formed on the mounting plate 2, and the lower end of the positioning pin force spring 33 is supported on the positioning pin step 322 formed on the upper end of the positioning pin 32. The middle part of the locking member 36 passes through the positioning pin locking member hole 321, which is opened in the middle of the height direction of the positioning pin 32 and penetrates the diameter of the positioning pin 32. The front end and rear end of the locking member 36 abut against the positioning pin seat 31 after protruding from the locking member guide clearance groove 312. The sliding flange device 34 is provided at the bottom right end of the frame 11. The sliding flange device 34 corresponds to and cooperates with the sliding flange guide limiting device 35, which is provided on the upper part of the mounting plate 2.

[0032] Based on the above explanation and in combination Figures 1 to 3It is known that the positioning pin seat 31 has a guide groove 312 for the locking element, and the positioning pin 32 has a positioning pin locking hole 321. The locking element 36, i.e., the open groove (also called the stop pin), passes through the positioning pin locking element 321 and the locking element guide groove 312 in sequence to realize the positioning pin 32's limiting and lifting functions, i.e., to realize the positioning pin 32's up and down displacement function. When the locating pin 32 moves upward, its lower end disengages from the locating pin latch hole 21, allowing the frame 11 to slide relative to the mounting plate 2 within the groove length range of the first and second flange guide limiting grooves 351 and 352. As previously mentioned, when the first and second sliding bosses 341 and 342 move to their corresponding positions corresponding to the first and second arc-shaped holes 3511 and 3521, the frame 11 is then lifted upward, causing the locating pin 32 to compress under the reaction force of the spring 33 against the locating pin force, and thus disengaging (unlocking) the locating pin 32 from the locating pin latch hole 21. This allows the first and second sliding bosses 341 and 342 to disengage from the first and second arc-shaped holes 3511 and 3521, separating the frame 11 from the mounting plate 2, facilitating the disassembly and assembly of the electromagnet assembly 1. The applicant will further explain this below.

[0033] When it is necessary to replace the electromagnet assembly 1, first pull upwards to lift the positioning pin seat 31 or the frame 11. Since the positioning pin 32 cooperates with the positioning pin seat 31 and is connected by the locking member 36, when the frame 11 or the positioning pin seat 31 is lifted upwards, the positioning pin 32 will exit the positioning pin latch hole 21 under the reaction force of the spring 33 overcoming the positioning pin force. At this time, push the frame 11, or positioning pin seat 31, to the right, so that the first and second sliding flanges 341 and 342 of the sliding flange device 34 move to the right along the first and second flange guide limiting grooves 351 and 352 of the sliding flange guide limiting device 35, respectively, corresponding to the first and second arcs 3511 and 3521. Then the electromagnet assembly 1 can be separated from the mounting plate 2 for replacement as needed. Since the process of replacing electromagnet component 1 is the reverse of the aforementioned process, and since it can be understood by analogy, the applicant will not elaborate further.

[0034] As can be seen from the above description, both disassembling and installing electromagnet assembly 1 can be done by the operator by hand, without relying on any tools, and without being affected by space or other components.

[0035] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
