If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element. If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are for illustrative purposes only and are not the only embodiment.

[0059] Referring to Figure 1 and Figure 2 , Figure 1 The structure of the switch device in an embodiment of the present application is shown. The switch device provided by the embodiment of the present application comprises a housing assembly 10, a first electrical assembly 20 and a second electrical assembly 30. The first electrical assembly 20 and the second electrical assembly 30 are directly or indirectly mounted on the housing assembly 10, and the first electrical assembly 20 and the second electrical assembly 30 can be mutually docked along a first direction X, and the first electrical assembly 20 and the second electrical assembly 30 are connected to each other when they are mutually docked.

[0060] Specifically, the first electrical component 20 is a power transmission component, and the second electrical component 30 is a bushing component. When the first electrical component 20 and the second electrical component 30 are mutually docked, the first electrical component 20 can be inserted into the second electrical component 30, so that the first electrical component 20 can be electrically connected with the second electrical component 30, thereby enabling the current on the first electrical component 20 to be transmitted to the external device of the switch device through the second electrical component 30.

[0061] It can be understood that in other embodiments, the first electrical component 20 and the second electrical component 30 can also be both power transmission components, or one of the first electrical component 20 and the second electrical component 30 is a power transmission component and the other is a switch component, etc., as long as the components that need to be mutually docked in the switch device. At the same time, the way in which the first electrical component 20 and the second electrical component 30 are connected to each other can be the above-mentioned insertion connection, or the first electrical component 20 and the second electrical component 30 can be aligned and then connected by bolts or buckles to complete the mutual docking.

[0062] In actual use, due to the cumulative machining errors of parts, the first electrical component 20 and the second electrical component 30 can deviate from the original design position, which can cause the first electrical component 20 and the second electrical component 30 to be unable to be quickly docked, thereby affecting the efficiency and accuracy of the docking of the first electrical component 20 and the second electrical component 30. Therefore, the first electrical component 20 is movable relative to the housing component 10 along a second direction Y intersecting the first direction X, i.e., the position of the first electrical component 20 relative to the housing component 10 can be adjusted, so that the first electrical component 20 can be accurately docked with the second electrical component 30 by adjusting the relative position of the housing component 10.

[0063] However, in the process of docking the first electrical component 20 and the second electrical component 30, since the first electrical component 20 is arranged inside the housing component 10, and the first electrical component 20 is a power transmission component as described above, even if the first electrical component 20 can be moved to facilitate the docking of the first electrical component 20 and the second electrical component 30, it is not convenient for the user to reach into the housing component 10 to move the first electrical component 20, thereby affecting the accurate or quick docking of the first electrical component 20 and the second electrical component 30.

[0064] Based on this, reference is made to Figure 3 and Figure 4The switchgear also includes a mounting device 40, which assists in the docking between the first electrical component 20 and the second electrical component 30. Users can directly manipulate the mounting device 40 from outside the housing assembly 10 without needing to reach inside, enabling rapid and accurate positioning of the first electrical component 20. The mounting device 40 includes a connecting plate 100, two adjusting components 200, and a bracket 300. The two adjusting components 200 are located at opposite ends of the connecting plate 100 in the second direction Y. Each adjusting component 200 is movably mounted on the housing assembly 10 of the switchgear along the second direction Y. By adjusting the positions of the two adjusting components 200 relative to the housing assembly 10, the position of the connecting plate 100 relative to the housing assembly 10 is adjusted.

[0065] Furthermore, one end of the bracket 300 is connected to the connecting plate 100, and the other end is used to connect to the first electrical component 20, so that the bracket 300 connects the first electrical component 20 and the connecting plate 100 to each other. When the adjusting component 200 adjusts the position of the connecting plate 100 relative to the housing component 10, the bracket 300 can drive the first electrical component 20 to move relative to the housing component 10, thereby adjusting the position of the first electrical component 20 relative to the second electrical component 30. Finally, the first electrical component 20 can quickly and accurately reach the docking position, so that the first electrical component 20 and the second electrical component 30 can dock quickly and accurately.

[0066] Specifically Figure 1 In this embodiment, the first direction X is the vertical direction, the second direction Y is the horizontal direction, and by adjusting the position of the adjusting component 200, the adjusting component 200 can drive the connecting plate 100 to move left and right, thereby compensating for the horizontal error of the first electrical component 20 and the second electrical component 30, and realizing the rapid and accurate docking of the first electrical component 20 and the second electrical component 30 in the vertical direction.

[0067] In the embodiments of this application, see Figure 2 The first electrical component 20 includes an intermediate conductor 21, and the switchgear includes two connecting sleeves 22. The two connecting sleeves 22 are respectively provided with the intermediate conductor 21 at opposite ends in the second direction Y, and the two ends of the intermediate conductor 21 are respectively inserted into the two connecting sleeves 22, so that the intermediate conductor 21 can be electrically connected to the two connecting sleeves 22, and the intermediate conductor 21 is electrically connected to other electrical components inside the switchgear through the two connecting sleeves 22.

[0068] Each of the connecting sleeves 22 is fixedly connected with the shell, and the intermediate conductor 21 is inserted into the two connecting sleeves 22 to enable the intermediate conductor 21 to move between the two connecting sleeves 22 along the second direction Y, and the relative position of the intermediate conductor 21 relative to the shell is changed by changing the depth of the intermediate conductor 21 inserted into the two connecting sleeves 22.

[0069] Further, referring to Figure 2 and Figure 13 , the connecting sleeves 22 are provided with connecting flanges 23, the first shell 11 and the second shell 12 of the shell assembly 10, the first shell 11 is provided with a first flange 13, and the second shell 12 is provided with a second flange 14, the first shell 11 includes two, two first shells 11 are respectively arranged at two ends of the second shell 12 in the second direction Y, and the connecting flange 23 is arranged between each of the first shell 11 and the second shell 12, the first flange 13, the connecting flange 23 and the second flange 14 are connected by bolts or the like, so that the connecting flange 23 is connected with the first shell 11 and the second shell 12, thereby connecting the connecting sleeve 22 with the shell assembly 10, and realizing the fixation of the connecting sleeve 22.

[0070] Further, referring to Figure 4 , the adjusting assembly 200 includes a pressing plate 210, a guide rod 220 and an adjusting nut 230, the pressing plate 210 is connected with the connecting plate 100 at one end along the first direction X, and the guide rod 220 is movably arranged at the other end of the pressing plate 210 along the second direction Y. A plurality of first flange holes 15 are formed on the second flange 14 of the second shell 12, and the axis of each of the first flange holes 15 extends longitudinally along the second direction Y. The guide rod 220 can be threadedly connected with one of the first flange holes 15, so that the guide rod 220 can be fixed with the first flange 13. It can be understood that in other embodiments, the guide rod 220 can be connected with the shell assembly by insertion, buckling or the like.

[0071] Further, referring to Figure 5 and Figure 6The guide rod 220 has a guide thread 221 extending longitudinally in the second direction Y. The adjusting nut 230 has an internal thread that is threadedly connected to the guide thread 221 on the guide rod 220. The adjusting nut 230 is located between the housing assembly 10 and the pressure plate 210. As the adjusting nut 230 moves along the guide thread 221, it abuts against the pressure plate 210. In actual use, controlling the rotation of the adjusting nut 230 relative to the guide rod 220 will cause the adjusting nut 230 to move along the guide thread 221 until it abuts against the pressure plate 210. Continuing to control the rotation of the adjusting nut 230 relative to the guide rod 220 will push the pressure plate 210 to move relative to the guide rod 220 in the second direction Y. This causes the pressure plate 210 to move the connecting plate 100 relative to the housing assembly 10 in the second direction Y, thereby changing the position of the first electrical component 20 relative to the housing.

[0072] Specifically Figure 1 In this embodiment, two adjustment components 200 are symmetrically arranged on opposite sides of the bracket 300. When it is necessary to control the connecting plate 100 to drive the first electrical component 20 to move to the left, the adjustment nut 230 of the right adjustment component 200 can be rotated; conversely, when it is necessary to control the connecting plate 100 to drive the first electrical component 20 to move to the right, the adjustment nut 230 of the left adjustment component 200 can be rotated. By adjusting the nut 230 to change the position of the first electrical component 20, the first electrical component 20 can be adjusted relative to the housing by a small margin, thereby improving the accuracy of the docking between the first electrical component 20 and the second electrical component 30. It is understood that when one adjustment nut 230 is adjusted, the position of the other adjustment nut 230 also needs to be adjusted accordingly to avoid the two adjustment nuts 230 interfering with each other and causing the connecting plate 100 to be unable to move.

[0073] In a specific embodiment, a limiting platform 224 is provided on the guide rod 220. The limiting platform 224 has a polygonal cross-section, so that at least one set of parallel planes are provided on the limiting platform 224. The limiting platform 224 is located in the middle of the guide rod 220, so as to break the guide rod 220 into two parts. The guide rod 220 has an adjusting thread on one side of the limiting platform 224 and an installation thread 223 on the other side. The center lines of the adjusting thread and the guiding thread 221 are parallel, and the center line of the limiting platform 224 is parallel to the center lines of the adjusting thread and the guiding thread 221. The guide rod 220 is threadedly connected to the first flange hole 15 through the installation thread 223, thereby fixing the guide rod 220 and the second flange 14 to each other. The limiting platform 224 can simultaneously limit the guide rod 220 and the adjusting nut 230. The limiting platform 224 can not only prevent the guide rod 220 from going too deep into the first flange hole 15, but also prevent the adjusting nut 230 from falling off the guide rod 220.

[0074] In the embodiments of the present application, referring to Figure 7 , the pressing plate 210 in each adjusting assembly 200 is provided with a first strip-shaped hole 211 penetrating through in the second direction Y, the first strip-shaped hole 211 extends longitudinally in the first direction X, and the guide rod 220 penetrates through the first strip-shaped hole 211. In actual use, according to the size of the first flange 13, the position of the first flange hole 15 is also different, at this time, the movement of the guide rod 220 in the first strip-shaped hole 211 can be controlled to adapt to the first flange hole 15 in different positions. Among them, the circumferential direction size of the adjusting nut 230 is greater than the width of the first strip-shaped hole 211, so as to avoid the nut from entering the first flange hole 15.

[0075] Further, the pressing plate 210 is provided with an opening 212 on the end away from the connecting plate 100 in the first direction X, the opening 212 is in communication with the first waist-shaped hole, so as to facilitate the installation of the guide rod 220 into the first waist-shaped hole through the opening 212. Referring to Figure 8 and Figure 9 , the end of the pressing plate 210 towards the connecting plate 100 is provided with a connecting through hole 213, the connecting plate 100 is provided with a connecting threaded hole 140 at both ends in the second direction Y, the axes of the connecting through hole 213 and the connecting threaded hole 140 are parallel to the second direction Y. The mounting device 40 further comprises a connecting bolt 141, the connecting bolt 141 penetrates through the connecting through hole 213 and is threadedly connected with the connecting threaded hole 140, so as to connect the pressing plate 210 and the connecting plate 100 with each other.

[0076] In the embodiments of the present application, referring to Figure 2 and Figure 14 , the second shell 12 is further provided with an intermediate flange 16, the intermediate flange 16 is located between the two second flanges 14, the axis of the intermediate flange 16 is perpendicular to the axis of the second flange 14, and the axis of the intermediate flange 16 is parallel to the first direction X, and the intermediate flange 16 is provided with a plurality of second flange holes 17 arranged around the axis thereof. Further referring to Figure 8 , the connecting plate 100 is provided with a second strip-shaped hole 110 penetrating through in the first direction X, the second strip-shaped hole 110 extends longitudinally in the second direction Y, and the mounting device 40 further comprises a pre-tightening bolt 111, the pre-tightening bolt 111 penetrates through the second strip-shaped hole 110 and is used for threadedly connecting with the second flange hole 17, so that the pre-tightening bolt 111 can be connected with the shell assembly 10, thereby fixing the connecting plate 100 on the shell assembly 10 through the pre-tightening bolt 111.

[0077] In actual use, the connecting plate 100 can be fixed on the housing assembly 10 through the pre-tightening bolt 111 first, and then the guide rod 220 is arranged in the first strip-shaped hole 211 and connected with the housing assembly 10. When the position of the connecting plate 100 is adjusted by the adjusting bolt, the pre-tightening bolt 111 moves in the second strip-shaped hole 110, so that the interference between the pre-tightening bolt 111 and the connecting plate 100 is avoided.

[0078] In the embodiment of the present application, the position of the bracket 300 relative to the connecting plate 100 in the second direction Y intersecting the first direction X is adjustable, so that the bracket 300 can be connected with the first electrical assembly 20 in different positions by adjusting the position of the bracket 300 relative to the connecting plate 100, thereby improving the adaptability of the mounting device 40.

[0079] Specifically, referring to Figure 10 , Figure 11 and Figure 12 , the bracket 300 includes a top plate 310, a main body frame 320 and a bottom plate 330, the top plate 310 and the bottom plate 330 are respectively arranged at the two ends of the main body frame 320 in the first direction X, a plurality of mounting holes 311 are arranged on the top plate 310 around the axis of the top plate 310, and fasteners such as bolts can be arranged in the mounting holes 311 and connected with the first electrical assembly 20, so that the top plate 310 can be connected with the first electrical assembly 20. It can be understood that in other embodiments, the top plate 310 can also be connected with the first electrical assembly 20 by buckling or other means, which is not limited herein.

[0080] Further, referring to Figure 4 , the mounting device 40 further includes a top rod 400, the connecting plate 100 is provided with a first threaded hole 120 penetrating in the first direction X, the top rod 400 is threadedly connected with the first threaded hole 120 and abuts against the bottom plate 330. In this way, when the top rod 400 moves in the first threaded hole 120, the top rod 400 drives the bottom plate 330 to move together, thereby pushing the bottom plate 330 to move in the first direction X. Alternatively, the top rod 400 and the first threaded hole 120 each include a plurality of top rods 400 and first threaded holes 120, which collectively support the movement of the bottom plate 330 in the first direction X, and in the embodiment of Figure 3 , the first threaded hole 120 and the top rod 400 each include two, and the two first threaded holes 120 and the two top rods 400 are respectively located on the same diameter of the bottom plate 330.

[0081] Further, the connecting plate 100 is further provided with a first through hole 130 penetrating along the first direction X, the bottom plate 330 is further provided with a second through hole 331 penetrating along the first direction X, the mounting device 40 further comprises a limiting bolt 350 and a limiting nut 360, the limiting bolt 350 penetrates the first through hole 130 and the second through hole 331, the limiting nut 360 is threadedly connected with the limiting bolt 350, and the limiting nut 360 and the screw head of the limiting bolt 350 are respectively located on the opposite sides of the connecting plate 100 in the first direction X. When the bottom plate 330 moves in the first direction X by the top rod 400, the limiting bolt 350 also moves in the first through hole 130 and the second through hole 331, and through the cooperation of the limiting bolt 350, the first through hole 130 and the second through hole 331, the limiting effect on the movement direction of the bottom plate 330 is achieved.

[0082] In the embodiments, referring to Figure 12 The main frame 320 is provided with an opening 321 in the circumferential direction, the opening 321 is in communication with the interior of the main frame 320, so that the main frame 320 is not closed, and thus the dismounting tool can pass through the main frame 320 through the opening 321, so as to facilitate the dismounting and mounting of various fasteners and other components on the mounting device 40 or the switch device. Further, the opening 321 can penetrate the main frame 320 along the second direction Y, so that the dismounting tool can pass through the opening 321 to dismount the components at other positions. Further, the bottom plate 330 and the top plate 310 are further provided with a reinforcing rib 312, so as to improve the mounting strength of the top plate 310 and the floor.

[0083] Based on the mounting device 40 in any of the above embodiments, the application further provides a method for mounting a bushing, based on the first electrical component 20 being a power transmission component and the second electrical component 30 being a bushing component, the method comprising:

[0084] S1: placing the mounting device 40 on the housing component 10 of the switch device through the two adjusting components 200;

[0085] S2: connecting the support 300 with the first electrical component 20;

[0086] S3: adjusting the position of each adjusting component 200 relative to the housing component 10, so that the first electrical component 20 and the second electrical component 30 are aligned in the first direction X;

[0087] S4: controlling the second electrical component 30 to be in mutual butt joint with the first electrical component 20.

[0088] Wherein, before step S1, the installation device 40 can be pre-fixed by pre-tightening the bolt 111, and in step S3, the first electrical component 20 can be moved by pushing the connecting plate 100 through adjusting the position of the adjusting nut in each adjusting assembly, and finally the alignment of the first electrical component 20 and the second electrical component 30 is achieved to complete the mutual docking of the first electrical component 20 and the second electrical component 30.

[0089] In actual use, referring to Figure 15 and Figure 16 When the intermediate conductor 21 in the first electrical component 20 fails during operation, after the power supply component is powered off, the intermediate conductor 21 needs to be disassembled, and the shell can be disassembled only after the intermediate conductor 21 is disassembled. Since the two ends of the intermediate conductor 21 are inserted into the two connecting sleeves 22, that is, the intermediate conductor 21 is of an inserted structure, the intermediate conductor 21 can move and rotate axially, and when disassembled, the tool will transmit artificial force to make the intermediate conductor 21 rotate axially, so that the screw and the intermediate conductor 21 will rotate together and cannot be disassembled. By fixing the internal conductor and the shell through the installation device 40, the intermediate conductor 21 cannot move and rotate axially when disassembled, and the disassembly tool can easily disassemble the fastening screw through the non-closed space of the main body frame 320.

[0090] The installation device 40 has at least the following advantages:

[0091] 1. The installation device 40 can continuously adjust the power supply component in the switchgear in the horizontal direction to quickly find the docking position of the power supply component through the installation device 40, thereby improving the docking efficiency and quality of the power supply component and the sleeve component.

[0092] 2. The installation device 40 has adjustability in the vertical direction of the assembly height, and the height of the guide rod 220 can be adjusted through the first slot 211 to meet the assembly requirements.

[0093] 3. The installation device 40 can fix the internal power supply component of the switchgear and prevent it from rotating, and the main body frame 320 in the installation device 40 is designed to be non-closed, so that the disassembly tool can disassemble and fasten the fastening screw in the internal power supply component through the non-closed space.

[0094] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0095] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
