Abstract
Description
Technical Field
[0001] This application relates to the field of low-voltage electrical technology, and more specifically, to a switch body and a rotary disconnect switch. Background Technology
[0002] With the advancement of technology and the rapid improvement of people's living standards, there is a greater demand for electrical safety. A rotary disconnect switch is a disconnect switch operated by turning. Its main functions are to isolate power sources, perform switching operations, and connect and disconnect low-current circuits, providing effective protection for lines and electrical equipment.
[0003] When wiring existing rotary disconnect switches, screws are usually used directly on the switch body. This wiring method requires screws and other components inside the switch body to make the connection, which takes up a lot of space. In addition, when using screw wiring, the user needs to operate from two directions simultaneously (tightening the screw in one direction and inserting the wire in the other direction) to complete the wiring, which also makes the wiring operation more complicated and difficult.

[0016] Optionally, the switch module is configured inside the chassis, and the side of the switch module with the wiring tube corresponds to the window of the chassis, so that the wiring tube can be plugged and unplugged through the window.

[0025] This application provides a switch body and a rotary disconnector, including a switch module and a contact component and a wiring conduit disposed in the switch module. The contact component is driven to close or open, and the wiring conduit is connected to the contact component. The switch module is used to insert and remove wires through the wiring conduit. Therefore, when the switch body uses a wiring conduit for wiring: on the one hand, the structure of the wiring conduit allows the end of the wire to be directly inserted into or removed from the wiring conduit, thus simplifying the complex operation of wiring the switch body; on the other hand, based on the structure of the wiring conduit, when the end of the wire is directly inserted into the wiring conduit, the wiring conduit can cover the outer wall of the wire, thus forming a reliable electrical connection between the two; furthermore, since the wire is directly inserted and removed through the wiring conduit, fewer components are required for wiring the switch body, eliminating the need for screws and other components, thus reducing the space occupied and simplifying the layout of components within the switch body, while also contributing to the miniaturization of the switch body.

Detailed Implementation
[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. It should be noted that, in the absence of conflict, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.
[0044] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and simplifying the description, and therefore should not be construed as limiting this application. In addition, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0045] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0046] One aspect of this application provides a switch body, such as... Figures 1 to 3 As shown, the system includes a switch module 120, a contact assembly disposed within the switch module 120, and a wiring conduit 130. This allows for plug-and-play wiring of the switch body via the wiring conduit 130, avoiding the need for screws 140 and other components inside the switch body, thus reducing the space occupied by the wiring section. Specifically:
[0047] like Figure 1 As shown, contact assembly ( Figure 1 (Not shown) is installed in the switch module 120, and the contact component has a closed state and an open state. Correspondingly, when the contact component is in the closed state, it means that the circuit of the switch module 120 is connected, and when the contact component is in the open state, it means that the circuit of the switch module 120 is disconnected. The contact component can be switched between the closed state and the open state by driving the contact component to move.
[0048] like Figure 1 and Figure 2As shown, the wiring conduit 130 is also disposed in the switch module 120, and the wiring conduit 130 is electrically connected to the contact component. Therefore, when wiring the switch body is required, the end of the wire 150 can be inserted into the wiring conduit 130, making contact between the wire 150 and the inner wall of the wiring conduit 130, forming an electrical connection between the wire 150 and the wiring conduit 130. This connects the contact component (i.e., the switch module 120 or the switch body) electrically connected to the wiring conduit 130 into the circuit. Thus, the on / off control of the circuit connected to the switch body can be achieved by switching the closed and open states of the contact component. When disconnection is required, the end of the wire 150 can be pulled out from the inside of the wiring conduit 130, separating the wire 150 from the wiring conduit 130 and terminating the electrical connection between the wire 150 and the wiring conduit 130.
[0049] Therefore, when the switch body uses the wiring tube 130 for wiring: on the one hand, the structural form of the wiring tube 130 allows the end of the wire 150 to be directly inserted into or pulled out of the wiring tube 130 to complete the wiring of the switch body, thereby simplifying the complicated operation of wiring the switch body; on the other hand, based on the structural form of the wiring tube 130, when the end of the wire 150 is directly inserted into the wiring tube 130, the wiring tube 130 can cover the outer peripheral wall of the wire 150, thereby forming a reliable electrical connection between the two; furthermore, since the wire 150 is directly inserted and pulled out of the wiring tube 130, fewer components are required for wiring the switch body, eliminating the need for components such as screws 140, and the space occupied is smaller, which can reduce the layout difficulty of various components in the switch body and is also conducive to the miniaturization of the switch body.
[0050] In some embodiments, to further improve the contact stability between the wire 150 and the conduit body 130, the wire 150 can be inserted into the conduit body 130 with an interference fit.
[0051] In some implementations, such as Figure 3 As shown, the wire 150 may include a wire body 153, a plug 151, and a sheath 152. The plug 151 serves as a conductor at the end of the wire body 153, while the sheath 152 acts as an insulator, covering the outer periphery of both. The end of the plug 151 has an exposed portion relative to the sheath 152. When connecting the wire 150 to the conduit body 130, as shown... Figures 7 to 9 As shown, the exposed end of the plug 151 can be inserted into the conduit body 130. In some embodiments, the outer periphery of the sheath 152 may be provided with anti-slip grooves to facilitate stable handling by the user. In addition, the outer periphery of the sheath 152 may also be provided with an annular protrusion for cooperating with the limiting part 182 in subsequent embodiments.
[0052] In some implementation methods, please refer to Figure 1 and Figure 2 As shown, the contact component and the wiring tube 130 are both located within the switch module 120. Thus, the switch module 120 can effectively protect and electrically isolate the contact component and the wiring tube 130.
[0053] In some implementation methods, please refer to Figure 1 , Figure 2 and Figure 3 As shown, the inside of the connector body 130 is hollow, and a connector cavity 131 can be formed in the hollow area. At the same time, in order to facilitate the insertion of the plug 151 of the wire 150, a connector port 132 communicating with the connector cavity 131 can be opened at one end of the connector body 130.
[0054] In some implementations, such as Figure 1 and Figure 2 As shown, when the wiring conduit 130 is located inside the switch module 120, an opening 122 corresponding to the wiring port 132 of the wiring conduit 130 can be made on the switch module 120. Thus, when a wire 150 needs to be inserted, the end of the wire 150 can be inserted into the wiring cavity 131 of the wiring conduit 130 through the opening 122 and the wiring port 132, achieving quick wiring of the switch body. In some embodiments, wiring ports 132 can be provided at both opposite ends of the wiring conduit 130; this application does not impose any limitations on this.
[0055] In some implementations, such as Figure 3 As shown, a slit 134 can be provided axially on the side wall of the connector body 130. The slit 134 can be a gap 134 that exists between the ends when the original material of the connector body 130 is bent to form the tube structure, or it can be a slit 134 that is opened on the integrally formed connector body 130. With the help of the slit 134, when the end of the wire 150 is inserted, it is convenient for the connector body 130 to match the deformation of the end of the wire 150, thereby achieving a tight contact between the wire 150 and the connector body 130.
[0056] In some embodiments, the radial cross-sectional shape of the conduit body 130 can be triangular, quadrilateral, pentagonal, or circular. Figure 3 The wire can take various shapes, such as elliptical, arbitrarily ring-shaped, etc., and this application does not limit them, as long as they can form an electrical connection with the end of the inserted wire 150. In order to further improve the contact reliability between the wire 150 and the terminal block 130, the shape of the end of the wire 150 can be matched with the shape of the terminal block 130.
[0057] In some implementations, such as Figure 1 and Figure 2As shown, it should be understood that there may be more than two wiring tubes 130 on the switch module 120. Therefore, each wiring tube 130 may have a certain width of gap 123 between it and the opening 122 of the switch module 120. In this way, compared with the wiring tube 130 directly contacting the inner wall of the opening 122, the creepage distance between two adjacent wiring tubes 130 can be effectively increased, thereby improving the reliability and stability of the switch body.
[0058] In some implementations, such as Figure 3 As shown, the contact assembly includes mating moving contacts ( Figure 3 (Not shown in the diagram) and stationary contact 160, in actual operation, the moving contact can be movably configured (e.g., rotated or slid) on the switch module 120. When driven, it can contact the stationary contact 160 (the contact assembly is in the closed state) or separate from the stationary contact 160 (the contact assembly is in the open state). Figure 3 As shown, when achieving electrical connection between the contact assembly and the conduit body 130, the stationary contact 160 can be connected to the conduit body 130. That is, one end of the stationary contact 160 can serve as the mating end with the moving contact, and the other end of the stationary contact 160 can be connected to the conduit body 130. For example, the moving contact and the conduit body 130 can be located on opposite sides of the stationary contact 160. It should be understood that the stationary contact 160 and the conduit body 130 can be integrally formed, or they can be separately formed and then connected by welding or other methods.
[0059] In some implementations, such as Figure 3 As shown, the conduit body 130 has a central axis 133. When connecting the end of the stationary contact 160 to the conduit body 130, the end of the stationary contact 160 can be offset relative to the central axis 133 of the conduit body, i.e., as shown... Figure 3 As shown, the end of the stationary contact 160 that connects to the wiring tube 130 is located above the central axis 133 of the tube. Of course, in other embodiments, the end of the stationary contact 160 that connects to the wiring tube 130 may also be located below the central axis 133 of the tube, or the end of the stationary contact 160 that connects to the wiring tube 130 may be on the same plane as the central axis 133 of the tube.
[0060] In some implementations, the switch body can be wired on one side or on both sides, such as... Figure 1 and Figure 2 As shown, for easy differentiation, the opposite sides of the switch module 120 can be considered as the front side (e.g., Figure 1 (as shown above) and back (as shown below) Figure 2As shown above, the front can be the window of the chassis 10 on which the switch module 120 is installed, facing the switch body. When the switch body needs to be wired on both sides, the wiring tube 130 can include at least two, and the at least two wiring tubes 130 are divided into two groups, one group is distributed on the front of the switch module 120, and the other group is distributed on the back of the switch module 120, so that the wiring on both sides of the switch module 120 can be performed.
[0061] In some implementations, such as Figure 1 , Figure 2 and Figure 4 As shown, the switch module 120 includes multiple switch units 121 arranged in a straight line. Each switch unit 121 has interconnected contact components and wiring conduits 130, allowing each switch unit 121 to connect to a circuit via the wiring conduit 130 and control the on / off state of that circuit. It should be understood that the contact components in each switch unit 121 can be a set, but the wiring conduits 130 corresponding to the contact components can be one, two, or more. The specific selection depends on the required breakpoint in the switch unit 121.
[0062] For example Figure 1 and Figure 2 As shown, the switch module 120 includes eight switch units 121. Each switch unit 121 is provided with a set of contact components and two wiring conduits 130 connected to the set of contact components. That is, the entire switch module 120 has sixteen wiring conduits 130. Figure 1 As shown, eight conduit bodies 130 are distributed on the front of the switch module 120. These eight conduit bodies 130 are arranged in two rows, each row along the length direction b of the switch module 120, and the conduit bodies 130 between the two rows are staggered to increase the creepage distance; as shown Figure 2 As shown, eight additional conduit bodies 130 are distributed on the back of the switch module 120. These eight conduit bodies 130 are also arranged in two rows, each row along the length direction b of the switch module 120, and the conduit bodies 130 between the two rows are staggered to increase the creepage distance; combined with Figure 1 and Figure 2 As shown, the two wiring tubes 130 connected to the same contact component can be located on the front and back of the switch module 120, respectively. In combination with the staggered distribution of the wiring tubes 130, the creepage distance can be increased while the overall volume of the switch module 120 can be effectively reduced.
[0063] When there are two conduit bodies 130 in the switching unit 121, the contact assembly of the switching unit 121 can be a double-break structure. For example, in the circuit where the same switching unit 121 is located, the contact assembly includes a moving contact and two stationary contacts 160 that cooperate with the moving contact. When the two stationary contacts 160 are located on the front and back of the switching module 120 respectively, the two conduit bodies 130 are also located on the front and back of the switching module 120 respectively, and each conduit body 130 is connected to one stationary contact 160.
[0064] In some implementations, such as Figure 1 and Figure 4 As shown, a first latching portion 124 and a second latching portion 125 are respectively provided on two adjacent switch units 121, and the first latching portion 124 and the second latching portion 125 cooperate with each other. After the two adjacent switch units 121 are connected, the first latching portion 124 and the second latching portion 125 on the two adjacent switch units 121 are also in a latching and limiting state, and the limiting direction of the first latching portion 124 and the second latching portion 125 is in the same direction as the insertion and removal direction of the wire 150. For example, Figure 1 In this process, the first latching part 124 and the second latching part 125 are used to limit the two adjacent switch units 121 along direction a, thereby enhancing the overall strength in direction a. When the insertion and removal direction of the wire 150 is the same as that of direction a, the first latching part 124 and the second latching part 125 can be used to increase the overall structural strength of the switch module 120, and avoid the instability of each switch unit 121 due to the insertion and removal of the wire 150.
[0065] For example Figure 4 As shown, a plug-in protrusion (first snap-fit portion 124) extending toward the right switch unit 121 is provided on the left switch unit 121, and a plug-in groove (second snap-fit portion 125) for accommodating the plug-in protrusion of the left switch unit 121 is provided on the right switch unit 121. After the left switch unit 121 and the right switch unit 121 are connected, the plug-in protrusion is inserted laterally into the plug-in groove, thereby reinforcing the entire switch unit in the vertical direction a. When the wire 150 is vertically inserted and removed from the wiring tube 130 provided on the switch unit 121, the overall structural strength of the switch module 120 can be effectively increased.
[0066] In some implementations, such as Figure 5 and Figure 6As shown, the switch module 120 is disposed inside the chassis 10. The configuration can be achieved by connecting and fixing the switch module 120 to the inside of the chassis 10 with screws 140, or by other fixing methods such as snap-fit. After the switch module 120 is fixed inside the chassis 10, the side of the switch module 120 with the wiring conduit 130 should correspond to the window of the chassis 10, thus facilitating the insertion and removal of the wires 150 through the window and the wiring conduit 130 on the switch module 120. It should be noted that when the switch module 120 has dual-sided, triple-sided, or multi-sided wiring, only one side needs to correspond to the window of the chassis 10. It should also be understood that the correspondence between the wiring side of the switch module 120 and the window of the chassis 10 should include both direct and partial direct correspondence.
[0067] like Figure 7 and Figure 8 As shown, when the wire 150 is connected to the switch module 120 from the front, the plug 151 at the end of the wire 150 can pass through the window on the chassis 10 and be inserted into the wiring tube 130 inside the switch module 120 (switch unit 121).
[0068] like Figure 7 and Figure 9 As shown, when connecting the wire 150 to the back of the switch module 120, the plug 151 at the end of the wire 150 can be directly inserted into the wiring tube 130 inside the switch module 120 (switch unit 121).
[0069] In some implementations, such as Figure 5 and Figure 6 As shown, the switch body also includes a sealing assembly 170, which is installed at the window of the chassis 10. This sealing assembly 170 seals the window of the chassis 10, effectively isolating the interior and exterior of the chassis 10. It should be understood that the sealing assembly 170 can be as follows: Figure 5 and Figure 6 As shown, the window of the chassis 10 is sealed by the outside of the chassis 10. In other embodiments, the window of the chassis 10 may also be sealed by the inside of the chassis 10.
[0070] In some implementations, such as Figures 5 to 15As shown, the sealing assembly 170 includes an annular sealing seat 190 and a sealing cover 180 installed at the window of the chassis 10. The sealing cover 180 is detachably connected to the annular sealing seat 190. To facilitate wiring of the switch module 120 inside the chassis 10, mounting holes 183 are provided on the sealing cover 180. The mounting holes 183 connect through the inner ring of the annular sealing seat 190 to the wiring conduit 130 on the wiring side of the switch module 120. Thus, the end of the wire 150 can pass through the mounting holes 183 and the inner ring of the annular sealing seat 190 to be inserted into the wiring conduit 130. It should be understood that the number and position of the mounting holes 183 on the sealing cover 180 should correspond one-to-one with the number and position of the wiring conduits 130 on the wiring side of the switch module 120 and the window inside the chassis 10, thereby facilitating accurate wiring.
[0071] In some implementations, such as Figure 7 , Figure 10 and Figure 15 As shown, a limiting part 182 can be provided on the sealing cover 180. The limiting part 182 can cooperate and abut against the wire 150 passing through the mounting hole 183, thereby limiting the wire 150 within the sealing cover 180. For example, Figure 3 and Figure 15 As shown, after the end of the wire 150 passes through the mounting hole 183, the annular protrusion on the wire 150 abuts against the limiting part 182 on the sealing cover 180, thereby limiting the wire 150 to the sealing cover 180 and preventing it from falling off. Thus, when connecting the wire 150 to the switch module 120 inside the chassis 10, the wire 150 can be first assembled with the mounting hole 183 and the limiting part 182 of the sealing cover 180. At this time, since the sealing cover 180 is not yet connected to the annular sealing seat 190, the sealing cover... Assembling the wire 150 on the 180 is relatively easy and is not limited by the environment. Then, the sealing cover 180 with the wire 150 is installed on the annular sealing seat 190. The mounting hole 183 and the limiting part 182 can be used to position and limit the wire 150, so that the wire 150 can be aligned and inserted with the wiring tube 130 of the switch module 120. This completes the wiring of the switch module 120, which can effectively improve the wiring difficulties caused by environmental restrictions when wiring directly on the switch body in the traditional way, and reduce the labor intensity of users wiring.
[0072] Furthermore, due to the limiting part 182, after the wiring is completed, the limiting part 182 can mainly bear the weight of the wire 150, that is, the sealing cover 180 can bear the weight of the wire 150, thus ensuring the stability of the connection between the wire 150 and the switch module 120.
[0073] In some implementations, such as Figure 10 and Figure 15 As shown, the limiting part 182 is a limiting protrusion located around the mounting hole 183. It can be arranged in a ring shape. The limiting protrusion is located on the side of the sealing cover 180 near the annular sealing seat 190. In this way, after the wire 150 passes through the mounting hole 183, the annular protrusion on the wire 150 is positioned above the limiting protrusion and abuts against the limiting protrusion, thereby limiting the wire 150 to the side of the sealing cover 180 near the chassis 10 and preventing it from falling off. At the same time, during normal use, if it is necessary to check the state inside the chassis 10, since the annular protrusion on the wire 150 only abuts against the limiting protrusion in one direction, the sealing cover 180 can be easily removed from the annular sealing seat 190 without pulling the wire 150, thus preventing the wire 150 from becoming loose from the switch body.
[0074] In some implementations, such as Figure 7 and Figure 11 As shown, a first sealing ring 210 is provided between the annular sealing seat 190 and the chassis 10, surrounding the window. That is, when the annular sealing seat 190 is assembled to the window of the chassis 10 by screws 140, the first sealing ring 210 can be compressed to ensure a complete seal between the annular sealing seat 190 and the chassis 10. Figure 13 As shown, an annular groove 193 can also be opened on the side of the annular sealing seat 190 close to the chassis 10, and the first sealing ring 210 can be accommodated by the annular groove 193, thereby facilitating the fixing of the first sealing ring 210 and realizing the sealing between the annular sealing seat 190 and the chassis 10 by the first sealing ring 210.
[0075] In some implementations, such as Figure 7 and Figure 11 As shown, a second sealing ring 220 can also be provided between the annular sealing seat and the sealing cover 180. The second sealing ring 220 can be arranged around the inner ring of the annular sealing seat. That is, when the sealing cover 180 is assembled to the annular sealing seat 190 by the screw 140, the sealing cover 180 and the annular sealing seat 190 can be fully sealed by squeezing the second sealing ring 220.
[0076] In some implementations, such as Figure 14 and Figure 15 As shown, a positioning groove 194 can also be provided on the side of the annular sealing seat 190 close to the sealing cover 180. At the same time, a positioning protrusion 184 is provided on the side of the sealing cover 180 close to the annular sealing seat 190. When the sealing cover 180 and the annular sealing seat 190 are assembled and connected, the positioning groove 194 can be used to guide the positioning protrusion 184, so that the positioning protrusion 184 is inserted into the positioning groove 194, thereby realizing the quick and accurate alignment of the sealing cover 180 and the annular sealing seat 190, which is beneficial to improving the accurate insertion of the end of the wire 150 assembled on the sealing cover 180 into the wiring conduit body 130.
[0077] In some implementations, such as Figure 14 and Figure 15 As shown, the positioning groove 194 can be annular, and correspondingly, the positioning protrusion 184 on the sealing cover 180 can also be annular. The two are aligned and interlocked to achieve quick and accurate alignment of the sealing cover 180 and the annular sealing seat 190. Furthermore, the positioning groove 194 can accommodate the second sealing ring 220, facilitating its fixation. During the assembly of the sealing cover 180 and the annular sealing seat 190, the positioning protrusion 184 can press against the second sealing ring 220 within the positioning groove 194, thereby improving the sealing effect between the sealing cover 180 and the annular sealing seat 190.
[0078] In some implementations, such as Figure 7 and Figure 10 As shown, a third sealing ring 181 is also provided inside the mounting hole 183, which fits against the outer peripheral wall of the wire 150. Thus, the third sealing ring 181 can effectively seal the mounting hole 183. Figure 10 As shown, a groove can also be provided around the outer periphery of the third sealing ring 181. At the same time, a card is provided on the inner wall of the mounting hole 183 so that the card can be inserted into the groove around the outer periphery of the third sealing ring 181, thereby realizing the assembly of the third sealing ring 181 and the sealing cover 180.
[0079] In some implementations, such as Figure 5 and Figure 6 As shown, the switch module 120 is located inside the chassis 10, and the sealing assembly 170 is located outside the chassis 10, thus facilitating the assembly of the sealing assembly 170 to the chassis 10. At this time, the annular sealing seat 190 is installed on the outside of the chassis 10, and the inner ring of the annular sealing seat 190 corresponds to the position and size of the window. Figure 12 and Figure 13 As shown, a flange 191 can be provided on the side of the annular sealing seat 190 near the chassis 10. The flange 191 is fitted against the inner wall of the window. This tight fit between the inner wall and the flange 191 improves assembly convenience and enhances stability during long-term use. It should be understood that the flange 191 can be multiple independent block structures, which can correspondingly abut against the four walls of the window; of course, as... Figure 12 and Figure 13 As shown, the folded edge 191 can also be an annular folded edge 191, which fits and abuts against the perimeter wall of the window, thus improving the overall strength of the folded edge 191.
[0080] In some embodiments, a first fastening portion is provided on the annular sealing seat 190, and a second fastening portion is provided on the sealing cover 180. The sealing cover 180 is detachably connected to the annular sealing seat 190 by fastening the first and second fastening portions. For example... Figure 14 and Figure 15 As shown, a snap-fit protrusion 192 (first snap-fit portion) can be provided on the outer peripheral wall of the annular sealing seat 190, and an elastic snap 186 (second snap-fit portion) can be provided on the outer peripheral wall of the sealing cover 180. When assembling the sealing cover 180 and the annular sealing seat 190, the elastic snap 186 can be snapped onto the snap-fit protrusion 192. When disassembly is required, the elastic snap 186 can be deformed by external force, thereby releasing the snap-fit between the elastic snap 186 and the snap-fit protrusion 192, and realizing the separation of the sealing cover 180 and the annular sealing seat 190.
[0081] In some implementations, such as Figure 15 As shown, there are multiple limiting parts 182, and reinforcing ribs 185 can be provided between two adjacent limiting parts 182, thereby effectively improving the strength of the limiting parts 182 and the overall strength of the sealing cover 180. Figure 15 As shown, when there are multiple mounting holes 183, they can be arranged in two rows, with reinforcing ribs 185 between the two rows. In this way, the reinforcing ribs 185 can further improve the overall strength of the sealing cover 180, and at the same time, they can also increase the creepage distance between the two rows of mounting holes 183, thus achieving effective electrical isolation.
[0082] Another aspect of this application provides a rotary disconnect switch, such as... Figures 1 to 6 As shown, the switch body includes a rotary operation unit 110 and any of the above-mentioned switch bodies. The rotary operation unit 110 is driven to connect to the contact component in the switch module 120 of the switch body. Thus, by driving the rotary operation unit 110, the contact component can be controlled to switch between the closed and open states.
[0083] When the switch module 120 includes multiple switch units 121, the rotary operating part 110 can be driven to connect with the contact components of each switch unit 121, thereby enabling the rotary operating part 110 to drive all switch units 121 to close or open synchronously.
[0084] like Figure 5 As shown, in order to facilitate the operation of the rotary operating unit 110, a knob 111 connected to the rotary operating unit 110 can be provided on the outside of the housing 10. In this way, when the user needs to operate the rotary disconnect switch, he can rotate the knob 111 on the outside of the housing 10 to realize the on / off control of the circuit where the switch module 120 in the rotary disconnect switch is located.
[0085] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
