Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, and in particular to a housing assembly and a switching device. Background Technology

[0002] Switching devices control the on / off state of a circuit, reducing the possibility of faults escalating and providing protection for the circuit. Switching devices can be at least one of the following: disconnect switches, circuit breakers, relays, etc.

[0003] The housing assembly of the switchgear includes a housing body and mounting feet. One end of the mounting feet is connected to the housing body, and the other end of the mounting feet can be connected to a mounting structure. The mounting structure can be at least one of the following: switch cabinet, distribution cabinet, mounting plate, guide rail, etc.

[0004] Based on the existing housing assembly structure, during the use of the housing assembly, the mounting feet may accidentally rotate relative to the housing body, which may affect the reliability of the connection between the switching device and the mounting structure. Utility Model Content

[0005] This application provides a housing assembly and a switching device that can reduce the possibility of accidental rotation of the mounting feet relative to the housing body, ensure the reliability of the connection between the mounting feet and the housing body, and thus ensure the reliability of the connection between the switching device and the mounting structure.

[0006] In a first aspect, this application provides a housing assembly, which includes a housing body and mounting feet. The housing body has a first limiting structure. The mounting feet are connected to the housing body via a first connector and are rotatable relative to the housing body. The mounting feet have a second limiting structure that cooperates with the first limiting structure, and the second limiting structure is spaced apart from the first connector. The first limiting structure may have multiple spaced-apart structures, and / or the second limiting structure may have multiple spaced-apart structures.

[0007] In this example, the first connector enables the connection between the mounting leg and the housing body. The housing body has a first limiting structure, and the mounting leg has a second limiting structure, with the second limiting structure spaced apart from the first connector. Therefore, the first and second limiting structures, working together, can limit the connection between the mounting leg and the housing body from a position different from the first connector, ensuring the reliability of the connection between the mounting leg and the housing body, reducing the possibility of accidental rotation of the mounting leg relative to the housing body, and thus ensuring the reliability of the connection between the switching device and the mounting structure.

[0008] Furthermore, the first connector enables the connection between the mounting feet and the housing body. The mounting feet are rotatable relative to the housing body, allowing the positional relationship between the mounting feet and the housing body to be adjusted according to the installation environment. This makes the housing assembly suitable for different installation environments, expanding its applicability.

[0009] In some possible implementations, the first limiting structure is a first limiting hole, the second limiting structure is a second limiting hole, and the housing assembly also includes a second connector, which is movably mounted on the first limiting hole and the second limiting hole. The second connector can be separated from the mounting leg with the second limiting hole so that the mounting leg can rotate relative to the housing body.

[0010] In this application example, the first limiting structure is a first limiting hole, the second limiting structure is a second limiting hole, and the second connector is installed to the first limiting hole and the second limiting hole so that the second connector cooperates with the first connector to limit the engagement between the shell body and the mounting leg from different positions, thereby reducing the possibility of the mounting leg accidentally rotating relative to the shell body.

[0011] Since the second connector can be movably installed into the first limiting hole and the second limiting hole, when the mounting leg needs to rotate relative to the housing body, the second connector can be separated from the mounting leg with the second limiting hole, thereby releasing the limiting effect of the second connector on the housing body and the mounting leg, and allowing the mounting leg to rotate relative to the housing body, so that the housing assembly can be used in different installation environments and expand the application range of the housing assembly.

[0012] In some possible implementations, when there are multiple first limiting holes spaced apart, there are correspondingly multiple second connectors, with each first limiting hole allowing one second connector to pass through.

[0013] In this application example, when there are multiple first limiting holes spaced apart, a second connector is provided through each first limiting hole, so that multiple second connectors can cooperate with the first connectors to limit the relative position of the mounting feet and the shell body from different positions, further reducing the possibility of the mounting feet rotating accidentally relative to the shell body and ensuring the reliability of the connection between the mounting feet and the shell body.

[0014] In some possible implementations, the housing body has a first mounting groove located on the side of the first limiting hole opposite to the mounting foot, and the first mounting groove communicates with the first limiting hole. The end of the second connector away from the mounting foot has a snap-fit ​​protrusion that snaps into the groove wall of the first mounting groove communicating with the first limiting hole. The housing assembly also includes an elastic element, with a first end connected to the groove wall of the first mounting groove away from the first limiting hole, and a second end connected to the snap-fit ​​protrusion.

[0015] In this example, the first end of the elastic element is connected to the groove wall of the first mounting groove away from the first limiting hole, and the second end of the elastic element is connected to the snap-fit ​​protrusion, which is connected to the second connector. Therefore, during the separation of the second connector from the mounting leg with the second limiting hole, the second connector moves in the direction toward the shell body, and the elastic element can be deformed by compression. After the mounting leg rotates relative to the shell body, the force acting on the elastic element is released, and the elastic element provides a force toward the mounting leg to the second connector through the snap-fit ​​protrusion, so that the second connector can extend into the second limiting hole to limit the mounting leg and the shell body.

[0016] In addition, the second connector is provided with a snap-fit ​​protrusion, which can snap into the groove wall of the first mounting groove that connects to the first limiting hole, reducing the possibility of the second connector disengaging from the first limiting hole and the second limiting hole, and ensuring the reliability of the connection between the mounting leg and the housing body.

[0017] In some possible implementations, a first mounting structure is provided on the side of the snap-fit ​​protrusion facing the elastic member, and a first end of the elastic member is connected to the first mounting structure. And / or, a second mounting structure is provided on the groove wall of the first mounting groove away from the first limiting hole, and a second end of the elastic member is connected to the second mounting structure.

[0018] In this application example, since the first end of the elastic member is connected to the first mounting structure, and the first mounting structure is located on the side of the snap-fit ​​protrusion facing the elastic member, the assembly reliability of the elastic member and the snap-fit ​​protrusion can be guaranteed by the cooperation between the elastic member and the first mounting structure, and the possibility of the elastic member and the snap-fit ​​protrusion separating can be reduced.

[0019] Since the second end of the elastic element is connected to the second mounting structure, and the second mounting structure is located on the groove wall of the first mounting groove away from the first limiting hole, and the first mounting groove is located on the shell body, the assembly reliability of the elastic element and the shell body can be guaranteed by the cooperation of the elastic element and the second mounting structure, and the possibility of the elastic element and the shell body separating can be reduced.

[0020] In some possible implementations, the end of the second connector away from the snap-fit ​​protrusion is provided with a guide surface, the inclination direction of which is adapted to the direction in which the second connector is installed into the first limiting hole and the second limiting hole.

[0021] In this example, the end of the second connector facing away from the snap-fit ​​protrusion has a guide surface, and the inclination direction of the guide surface is adapted to the direction in which the second connector is installed into the first and second limiting holes. Therefore, during the installation of the second connector into the first and second limiting holes, the smaller end of the second connector extends into the first and second limiting holes first, which improves the efficiency of the second connector extending into the first and second limiting holes and facilitates the assembly efficiency of the second connector, the housing body, and the mounting feet.

[0022] In some possible implementations, when there are multiple first limiting structures, the multiple first limiting structures are evenly arranged on the shell body.

[0023] In this application example, when there are multiple first limiting structures, the multiple first limiting structures are evenly distributed on the shell body, so that the force transmitted to the shell body by the mounting legs through the cooperating second limiting structures and the first limiting structures is more uniform, reducing the possibility of damage to the shell body due to uneven force transmitted to the shell body by the cooperating second limiting structures and the first limiting structures.

[0024] In some possible implementations, multiple first limiting structures are located on the periphery of the first connector.

[0025] In this application example, multiple first limiting structures are provided on the periphery of the first connector, so that the second limiting structure provided on the mounting leg can cooperate with any one of the first limiting structures on the periphery of the first connector, thereby making the range of rotation angle of the mounting leg relative to the shell body larger and further expanding the applicability of the shell assembly.

[0026] In some possible implementations, the shell body has a second mounting groove on the side wall facing the mounting feet, a first limiting structure is provided on the groove wall of the second mounting groove, and part of the mounting feet are installed into the second mounting groove.

[0027] In this application example, by providing a second mounting groove on the side wall of the shell body facing the mounting foot, and installing the mounting foot into the second mounting groove, the height of the mounting foot protruding from the side wall of the shell body where the second mounting groove is provided can be reduced, thereby reducing the possibility of the mounting foot being hit by a collision due to protruding from the shell body during the use of the shell assembly, and ensuring the assembly reliability of the mounting foot and the shell body.

[0028] Secondly, this application provides a switching device, including the housing assembly provided in the first aspect and various possible implementations of the first aspect.

[0029] The beneficial effects of the housing components provided in the second aspect and the various possible designs of the second aspect can be seen in the beneficial effects of the first aspect and the various possible implementations of the first aspect, and will not be repeated here.

Obviously, the described examples are only a part of the examples in this application, not all of them. Based on the examples in this application, all other examples obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terms used herein in the description of the application are for the purpose of describing particular examples only and are not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the description, claims and drawings of this application are intended to cover non-exclusive inclusion.

[0041] In this document, the term "example" means that a particular feature, structure, or characteristic described in connection with the example can be included in at least one example of this application. The appearance of the phrase "example" in various places in the specification does not necessarily refer to the same example, nor is it a separate or alternative example mutually exclusive with other examples. It will be explicitly and implicitly understood by those skilled in the art that the examples described herein can be combined with other examples.

[0042] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists, A and B exist simultaneously, or B exists. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0043] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the housing components of this application.

[0044] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0045] In the description of this application, unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple groups" means two or more (including two groups).

[0046] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, "connection" or "joining" in mechanical structures can refer to a physical connection, such as a fixed connection, for example, a connection fixed by a partition, such as a connection fixed by screws, bolts, or other partitions; a physical connection can also be a detachable connection, such as a snap-fit ​​or interlocking connection; a physical connection can also be an integral connection, such as a connection formed by welding, bonding, or integral molding.

[0047] Based on the above, this application provides a housing assembly and a switching device.

[0048] To enable those skilled in the art to better understand the present application, the housing assembly and switching device provided in the present application will be clearly and completely described below with reference to the accompanying drawings.

[0049] For example, this application provides a switching device that includes a housing assembly.

[0050] Switching devices can be disconnecting switches, circuit breakers, relays, or other switches.

[0051] Taking a disconnector switch as an example, the switchgear also includes an operating mechanism and a contact assembly. Both the operating mechanism and the contact assembly are mounted to the housing assembly. The contact assembly includes a cooperating stationary contact and a moving contact. The stationary contact is fixedly mounted to the housing assembly and is directly or indirectly connected to the power supply line to achieve electrical connection between the switchgear and the power supply line. The moving contact is rotatably mounted to the housing assembly. The operating mechanism can drive the moving contact to contact the stationary contact; at this time, the switchgear is in the closed state, and current flows through the circuit. The operating mechanism can also drive the moving contact to separate from the stationary contact; at this time, the switchgear is in the open state, and no current flows through the circuit.

[0052] Since the switching device provided in this application example includes the housing assembly described below, the switching device provided in this application example has the same effects as the housing assembly described below.

[0053] Exemplarily, this application provides a housing assembly, Figure 1 A schematic diagram of a housing assembly from a first-view perspective is provided as an example of this application. Figure 2 This application provides a schematic diagram of the structure of a shell body as an example. Figure 3 for Figure 2 A magnified view of a portion of point A in the diagram. Figure 4 Please refer to the structural diagram of an example mounting leg provided in this application. Figures 1-4 The housing assembly 100 includes a housing body 110 and mounting legs 120. The housing body 110 is provided with a first limiting structure 111. The mounting legs 120 are connected to the housing body 110 via a first connector and are rotatable relative to the housing body 110. The mounting legs 120 are provided with a second limiting structure 121, which cooperates with the first limiting structure 111. The second limiting structure 121 and the first connector are spaced apart. Multiple first limiting structures 111 are provided at intervals, and / or multiple second limiting structures 121 are provided at intervals.

[0054] The housing body 110 is made of insulating material, such as polyvinyl chloride, polycarbonate (also known as PC plastic), etc. The housing body 110 made of insulating material can reduce the possibility of current escaping from the housing body 110 to the outside of the mounting housing, so as to ensure the safety of the switch device.

[0055] One end of the mounting leg 120 is connected to the housing body 110, and the other end of the mounting leg 120 can be connected to the mounting structure. The mounting structure can be at least one of the following: switch cabinet, distribution cabinet, mounting plate, guide rail, etc.

[0056] The housing body 110 can be connected to multiple mounting feet 120. The multiple mounting feet 120 can be connected to the same mounting structure, or they can be connected to different mounting structures respectively. This application example does not make specific limitations in this regard.

[0057] The mounting feet 120 are made of metal materials such as cast iron, cast steel, and stainless steel. The mounting feet 120 made of metal materials have good mechanical strength and rigidity, and can bear the weight of the switching device, thereby ensuring the reliability of the connection between the housing body 110 and the mounting structure.

[0058] The mounting leg 120 is connected to the housing body 110 via a first connector. The first connector can be a screw, threaded rod, or other threaded component, or it can be a shaft or other structure. The housing body 110 has a first mounting hole 112, and the mounting leg 120 has a second mounting hole 122. Different parts of the first connector simultaneously extend into both the first mounting hole 112 and the second mounting hole 122 to achieve the connection between the housing body 110 and the mounting leg 120. As long as the connection between the mounting leg 120 and the housing body 110 is achieved via the first connector, and after the mounting leg 120 is connected to the housing body 110, the mounting leg 120 can rotate relative to the housing body 110 by loosening the first connector, or the mounting leg 120 can directly rotate relative to the housing body 110 under force, the connection is acceptable.

[0059] The housing body 110 is provided with a first limiting structure 111, and the mounting leg 120 is provided with a second limiting structure 121. The first limiting structure 111 and the second limiting structure 121 cooperate to limit the relative position of the mounting leg 120 and the housing body 110. Since the second limiting structure 121 is spaced apart from the first connecting member, the first limiting structure 111 and the second limiting structure 121 cooperate to limit the mounting leg 120 and the housing body 110 from a position different from that of the first connecting member. The first limiting structure 111 and the second limiting structure 121 can be connected by a hole-shaft fit, a spring latch and a groove fit, or by other structural fits.

[0060] There may be one first limiting structure 111, and in this case, there may be multiple second limiting structures 121. When the mounting leg 120 is in the initial position, the first limiting structure 111 engages with one of the multiple second limiting structures 121. After the mounting leg 120 rotates relative to the housing body 110, the first limiting structure 111 engages with another of the multiple second limiting structures 121.

[0061] Multiple first limiting structures 111 may be provided, in which case there is only one first limiting structure 111. When the mounting leg 120 is in the initial position, one of the multiple first limiting structures 111 engages with the second limiting structure 121. After the mounting leg 120 rotates relative to the shell body 110, another of the multiple first limiting structures 111 engages with the second limiting structure 121.

[0062] Multiple first limiting structures 111 and multiple second limiting structures 121 can be provided. In this case, when the mounting leg 120 is in the initial position, at least one first limiting structure 111 and one second limiting structure 121 are engaged. After the mounting leg 120 rotates relative to the shell body 110, the second limiting structure 121 engaged with the first limiting structure 111 changes, or both the first limiting structure 111 and the second limiting structure 121 are different from the first limiting structure 111 and the second limiting structure 121 engaged when the mounting leg 120 is in the initial position.

[0063] The initial position of the mounting leg 120 means that the length direction of the mounting leg 120 is parallel to the length direction of the shell body 110, specifically as follows: Figure 1 As shown.

[0064] In this example, the first connector enables the connection between the mounting leg 120 and the housing body 110. The housing body 110 is provided with a first limiting structure 111, and the mounting leg 120 is provided with a second limiting structure 121, with the second limiting structure 121 spaced apart from the first connector. Therefore, the first limiting structure 111 and the second limiting structure 121 cooperate to limit the connection between the mounting leg 120 and the housing body 110 from a position different from that of the first connector, ensuring the reliability of the connection between the mounting leg 120 and the housing body 110, reducing the possibility of accidental rotation of the mounting leg 120 relative to the housing body 110, and thus ensuring the reliability of the connection between the switching device and the mounting structure.

[0065] Compared to the prior art, where the angle of rotation of the mounting leg relative to the shell body is manually positioned by the operator, in this application example, since at least one of the first limiting structure 111 and the second limiting structure 121 is provided in multiple intervals, this description only takes the example of multiple intervals of the first limiting structure 111. The angle that the mounting leg 120 can rotate relative to the shell body 110 is at least the angle formed by two adjacent first limiting structures 111 and the first connecting member, which makes the positioning of the rotation angle of the mounting leg 120 relative to the shell body 110 more accurate and improves the positioning accuracy of the rotation angle of the mounting leg 120 relative to the shell body 110.

[0066] Furthermore, the first connector enables the connection between the mounting leg 120 and the housing body 110. The mounting leg 120 is rotatable relative to the housing body 110, allowing the mounting leg 120 to adjust its position relative to the housing body 110 according to the installation environment of the housing body 110. This makes the housing assembly 100 suitable for different installation environments, expanding the applicability of the housing assembly 100.

[0067] Based on the housing assembly 100 provided in the above example, please refer to Figure 3 In the case where multiple first limiting structures 111 are spaced apart, the multiple first limiting structures 111 are evenly arranged on the shell body 110.

[0068] Multiple first limiting structures 111 can be arranged around the first mounting member. Multiple first limiting structures 111 can cooperate to be arranged only around a portion of the first mounting member. For example, multiple first limiting structures 111 can cooperate to form an arc shape and be arranged around a quarter of the first mounting member.

[0069] The angle formed by two adjacent first limiting structures 111 in conjunction with the first connecting member can be 10°, 15° or other values.

[0070] In this application example, when multiple first limiting structures 111 are provided, multiple first limiting structures 111 are evenly distributed on the shell body 110, so that the force transmitted from the mounting leg 120 to the shell body 110 through the cooperating second limiting structure 121 and the first limiting structure 111 is more uniform, reducing the possibility of damage to the shell body 110 due to uneven force transmitted to the shell body 110 by the cooperating second limiting structure 121 and the first limiting structure 111.

[0071] Based on the housing assembly 100 provided in the above example, a plurality of first limiting structures 111 are disposed on the periphery of the first connector.

[0072] Since the first mounting hole 112 is provided on the shell body 110, and the first connector is installed to the shell body 110 through the first mounting hole 112, the plurality of first limiting structures 111 are provided on the periphery of the first connector. It can be understood that the plurality of first limiting structures 111 are provided on the periphery of the first mounting hole 112.

[0073] When multiple first limiting structures 111 are provided on the periphery of the first connector, multiple second limiting structures 121 may be provided on the periphery of the first connector, or multiple second limiting structures 121 may be provided only at a portion of the periphery of the first connector.

[0074] In this application example, multiple first limiting structures 111 are provided on the periphery of the first connector, so that the second limiting structure 121 provided on the mounting leg 120 can cooperate with any one of the first limiting structures 111 on the periphery of the first connector, thereby making the range of rotation angle of the mounting leg 120 relative to the shell body 110 larger, and further expanding the applicability of the shell assembly 100.

[0075] The setting of the second limiting structure 121 can be the same as or different from the setting of the first limiting structure 111. As long as at least one set of cooperating first limiting structure 111 and second limiting structure 121 can limit the shell body 110 and the mounting leg 120 from a position different from the first connector, after the mounting leg 120 is in the initial position and after the mounting leg 120 rotates relative to the shell body 110.

[0076] Based on the housing assembly 100 provided in the above example, Figure 5 A schematic diagram of a housing assembly provided as an example in this application is shown from a second-view perspective. Figure 6 for Figure 5 Sectional view at point AA. Figure 7 for Figure 6 Please refer to the enlarged view of section B in the middle. Figures 2-7 The first limiting structure 111 is a first limiting hole 1111, and the second limiting structure 121 is a second limiting hole 1211. The housing assembly 100 also includes a second connector 130, which is movably installed in the first limiting hole 1111 and the second limiting hole 1211. The second connector 130 can be separated from the mounting leg 120 with the second limiting hole 1211 so that the mounting leg 120 can rotate relative to the housing body 110.

[0077] The first limiting hole 1111 can be a blind hole or a through hole, and the second limiting hole 1211 is a through hole. The second connecting member 130 can be a pin or other shaft-like structure. One end of the second connecting member 130 is installed into the first limiting hole 1111, and the other end of the second connecting member 130 is installed into the second limiting hole 1211. The second connecting member 130 is movably installed into the first limiting hole 1111 and the second limiting hole 1211. When there is only one first limiting hole 1111, there is one second connecting member 130. When there are multiple first limiting holes 1111, there is at least one second connecting member 130, and the number of second connecting members 130 is less than or equal to the number of first limiting holes 1111.

[0078] Before the mounting leg 120 rotates relative to the housing body 110, the operator needs to apply force to the second connector 130, causing the second connector 130 to move away from the mounting leg 120, thereby separating the second connector 130 from the mounting leg 120. The limiting effect of the second connector 130 on the housing body 110 and the mounting leg 120 disappears, and the mounting leg 120 can rotate relative to the housing body 110. After the mounting leg 120 rotates to the target position, the target position of at least one second limiting hole 1211 corresponds to the position of the first limiting hole 1111 where the second connector 130 is installed. The end of the second connector 130 facing away from the housing body 110 can extend into the second limiting hole 1211, achieving the connection between the second connector 130 and the mounting leg 120. This allows the second connector 130, in conjunction with the first connector, to limit the connection between the housing body 110 and the mounting leg 120 from different positions.

[0079] The operator can apply force to the second connector 130 by pressing it directly, or by pressing a button or other structure.

[0080] After the mounting leg 120 is rotated to the target position, the second connecting member 130 can be inserted into the corresponding second limiting hole 1211 under the manual operation of the operator, or it can be inserted into the corresponding second limiting hole 1211 under the action of the elastic member. This application example does not make specific limitations in this regard.

[0081] In this application example, the first limiting structure 111 is the first limiting hole 1111, the second limiting structure 121 is the second limiting hole 1211, and the second connector 130 is installed to the first limiting hole 1111 and the second limiting hole 1211, so that the second connector 130 cooperates with the first connector to limit the engagement between the shell body 110 and the mounting leg 120 from different positions, thereby reducing the possibility of the mounting leg 120 accidentally rotating relative to the shell body 110.

[0082] Since the second connector 130 is movably installed to the first limiting hole 1111 and the second limiting hole 1211, when the mounting leg 120 needs to rotate relative to the housing body 110, the second connector 130 can be separated from the mounting leg 120 with the second limiting hole 1211, so that the limiting effect of the second connector 130 on the housing body 110 and the mounting leg 120 is released, thereby allowing the mounting leg 120 to rotate relative to the housing body 110, so that the housing assembly 100 can be used in different installation environments, expanding the applicability of the housing assembly 100.

[0083] Based on the housing assembly 100 provided in the above example, when multiple first limiting holes 1111 are provided at intervals, multiple second connectors 130 are provided accordingly, and each first limiting hole 1111 allows one second connector 130 to pass through.

[0084] When multiple first limiting holes 1111 are provided at intervals, multiple second limiting holes 1211 are provided correspondingly, and each second limiting hole 1211 corresponds one-to-one with a first limiting hole 1111. When the mounting leg 120 is in its initial position, each second connector 130 is installed into its corresponding first limiting hole 1111 and second limiting hole 1211. After the mounting leg 120 rotates relative to the housing body 110, the correspondence between the second limiting hole 1211 and the first limiting hole 1111 changes compared to when the mounting leg 120 is in its initial position. Some first limiting holes 1111 may rotate to a position where the mounting leg 120 does not have a second limiting hole 1211. These parts of the first limiting holes 1111 will remain in a state where they do not extend into the second limiting hole 1211. Another part of the first limiting hole 1111 corresponds to the position of a part of the second limiting hole 1211. The second connector 130 corresponding to the first limiting hole 1111 can extend into the corresponding second limiting hole 1211 to limit the relative position of the mounting leg 120 and the shell body 110.

[0085] Alternatively, if there are multiple first limiting holes 1111 spaced apart, when the mounting leg 120 is in the initial position, the number of second limiting holes 1211 may be different from the number of first limiting holes 1111. This example will not be described in detail here.

[0086] In this application example, when multiple first limiting holes 1111 are provided at intervals, a second connector 130 is provided through each first limiting hole 1111, so that multiple second connectors 130 can cooperate with the first connector to limit the relative position of the mounting leg 120 and the shell body 110 from different positions, further reducing the possibility of the mounting leg 120 rotating accidentally relative to the shell body 110, and ensuring the reliability of the connection between the mounting leg 120 and the shell body 110.

[0087] Based on the housing assembly 100 provided in the above example, please refer to Figures 5-7The housing body 110 is provided with a first mounting groove 113, which is located on the side of the first limiting hole 1111 away from the mounting leg 120. The first mounting groove 113 is connected to the first limiting hole 1111. The second connecting member 130 is provided with a snap-fit ​​protrusion 140 at one end away from the mounting leg 120. The snap-fit ​​protrusion 140 snaps into the groove wall of the first mounting groove 113 that is connected to the first limiting hole 1111. The housing assembly 100 also includes an elastic member 150. The first end of the elastic member 150 is connected to the groove wall of the first mounting groove 113 away from the first limiting hole 1111, and the second end of the elastic member 150 is connected to the snap-fit ​​protrusion 140.

[0088] The opening of the first mounting groove 113 is formed on the side wall of the shell body 110. The opening of the first mounting groove 113 can be circular, rectangular, or other shapes. The second connector 130 has a snap-fit ​​protrusion 140 on the side away from the mounting foot 120. The snap-fit ​​protrusion 140 can be a rectangular plate structure, a circular plate structure, or other structures, as long as it can snap into the groove wall of the first mounting groove 113 that connects to the first limiting hole 1111, so as to ensure the reliability of the connection between the second connector and the shell body 110.

[0089] The first mounting groove 113 is connected to the groove wall of the first limiting hole 1111, which means the groove wall of the first mounting groove 113 is close to the mounting leg 120.

[0090] The elastic element 150 can be a spring, an elastic sheet, or other structure. In this application, the example of the elastic element 150 being a spring is used for description only. The first end of the elastic element 150 can be connected to the groove wall of the first mounting groove 113 away from the first limiting hole 1111, and the second end of the elastic element 150 can be connected to the snap-fit ​​protrusion 140.

[0091] When the second connector 130 is installed into the first limiting hole 1111 and the second limiting hole 1211, the first end of the elastic member 150 can contact the groove wall of the first mounting groove 113 away from the first limiting hole 1111, and the second end of the elastic member 150 contacts the snap-fit ​​protrusion 140. At this time, the elastic member 150 is in a free state. Alternatively, when the second connector 130 is installed into the first limiting hole 1111 and the second limiting hole 1211, the first end of the elastic member 150 can abut against the groove wall of the first mounting groove 113 away from the first limiting hole 1111, and the second end of the elastic member 150 abuts against the snap-fit ​​protrusion 140. At this time, the elastic member 150 is in a compressed state.

[0092] When the second connector 130 is installed in the first limiting hole 1111 and the second limiting hole 1211, regardless of whether the elastic member 150 is in a free state or a compressed state, when the second connector 130 disengages from the second limiting hole 1211, the second connector 130 moves in the direction toward the shell body 110, applying a force to the elastic member 150, causing the elastic member 150 to be in a compressed state. Furthermore, when the mounting leg 120 rotates to the target position, the second limiting hole 1211 rotates to the position corresponding to the first limiting hole 1111. The mounting leg 120 contacts the elastic member 150 through the force applied by the second connector 130, and the elastic member 150 returns to its initial state. The elastic member 150 applies a force toward the mounting leg 120 to the second connector 130, allowing the second connector 130 to quickly extend into the second limiting hole 1211.

[0093] The elastic element 150 returning to its initial state refers to the state of the elastic element 150 when the second connector 130 is installed in the first limiting hole 1111 and the second limiting hole 1211.

[0094] In this example, the first end of the elastic element 150 is connected to the groove wall of the first mounting groove 113 away from the first limiting hole 1111, and the second end of the elastic element 150 is connected to the snap-fit ​​protrusion 140. The snap-fit ​​protrusion 140 is connected to the second connector 130. Therefore, during the process of separating the second connector 130 from the mounting leg 120 with the second limiting hole 1211, the second connector 130 moves in the direction toward the shell body 110, and the elastic element 150 can be deformed by being squeezed. After the mounting leg 120 rotates relative to the shell body 110, the force acting on the elastic element 150 is released, and the elastic element 150 provides a force toward the mounting leg 120 to the second connector 130 through the snap-fit ​​protrusion 140, so that the second connector 130 can extend into the second limiting hole 1211 to limit the mounting leg 120 and the shell body 110.

[0095] In addition, the second connector 130 is provided with a snap-fit ​​protrusion 140, which can snap into the groove wall of the first mounting groove 113 that connects to the first limiting hole 1111, reducing the possibility of the second connector 130 disengaging from the first limiting hole 1111 and the second limiting hole 1211, and ensuring the reliability of the connection between the mounting leg 120 and the shell body 110.

[0096] Based on the housing assembly 100 provided in the above example, please attend the meeting. Figure 7A first mounting structure 141 is provided on the side of the snap-fit ​​protrusion 140 facing the elastic member 150, and the first end of the elastic member 150 is connected to the first mounting structure 141. And / or, a second mounting structure 1131 is provided on the groove wall of the first mounting groove 113 away from the first limiting hole 1111, and the second end of the elastic member 150 is connected to the second mounting structure 1131.

[0097] The first mounting structure 141 can be a protruding structure or a recessed structure. Taking a spring as an example, if the elastic element 150 is a spring, when the first mounting structure 141 is a protruding structure, the first end of the spring can be fitted onto the protruding structure. When the first mounting structure 141 is a recessed structure, the first end of the spring can extend into the recessed structure and abut against the groove wall of the recessed structure.

[0098] The second mounting structure 1131 can be a protruding structure or a recessed structure. When the second mounting structure 1131 is a protruding structure, the second end of the spring can be fitted onto the protruding structure. When the second mounting structure 1131 is a recessed structure, the second end of the spring can extend into the recessed structure and abut against the groove wall of the recessed structure. The second mounting structure 1131 can be the same as or different from the first mounting structure 141.

[0099] When the first mounting structure 141 is provided on the side of the snap-fit ​​protrusion 140 facing the elastic member 150, the groove wall of the first mounting groove 113 away from the first limiting hole 1111 may not be provided with any structure, or a second mounting structure 1131 may be provided.

[0100] When the second mounting structure 1131 is provided on the groove wall of the first mounting groove 113 away from the first limiting hole 1111, the side of the snap protrusion 140 facing the elastic member 150 may not have any structure, or it may have the first mounting structure 141.

[0101] In this application example, since the first end of the elastic member 150 is connected to the first mounting structure 141, and the first mounting structure 141 is located on the side of the snap-fit ​​protrusion 140 facing the elastic member 150, the cooperation between the elastic member 150 and the first mounting structure 141 can ensure the assembly reliability of the elastic member 150 and the snap-fit ​​protrusion 140, and reduce the possibility of the elastic member 150 and the snap-fit ​​protrusion 140 separating.

[0102] Since the second end of the elastic element 150 is connected to the second mounting structure 1131, and the second mounting structure 1131 is located in the groove wall of the first mounting groove 113 away from the first limiting hole 1111, and the first mounting groove 113 is located in the shell body 110, the cooperation between the elastic element 150 and the second mounting structure 1131 can ensure the assembly reliability of the elastic element 150 and the shell body 110 and reduce the possibility of the elastic element 150 separating from the shell body 110.

[0103] Based on the housing assembly 100 provided in the above example, Figure 8 For an example of the mating structure between the second connector and the snap-fit ​​protrusion provided in this application, please refer to the schematic diagram. Figure 8 The second connector 130 has a guide surface 131 at one end away from the snap-fit ​​protrusion 140. The inclination direction of the guide surface 131 is adapted to the direction in which the second connector 130 is installed into the first limiting hole 1111 and the second limiting hole 1211.

[0104] The guide surface 131 can be an arc surface or a plane. By setting the guide surface 131, the end of the second connector 130 away from the limiting boss can be in the shape of a cone, a frustum, a cone, or other shapes.

[0105] In this application example, the end of the second connector 130 facing away from the snap-fit ​​protrusion 140 is provided with a guide surface 131, and the inclination direction of the guide surface 131 is adapted to the direction in which the second connector 130 is installed into the first limiting hole 1111 and the second limiting hole 1211. Based on this, during the process of installing the second connector 130 into the first limiting hole 1111 and the second limiting hole 1211, the smaller end of the second connector 130 extends into the first limiting hole 1111 and the second limiting hole 1211 first, which helps to improve the efficiency of the second connector 130 extending into the first limiting hole 1111 and the second limiting hole 1211, and facilitates the improvement of the assembly efficiency of the second connector 130, the shell body 110 and the mounting leg 120.

[0106] Based on the housing assembly 100 provided in the above example, please refer to Figure 2 and Figure 3 The shell body 110 has a second mounting groove 114 on the side wall facing the mounting feet 120. The first limiting structure 111 is provided on the groove wall of the second mounting groove 114, and part of the mounting feet 120 are installed into the second mounting groove 114.

[0107] In this application example, by providing a second mounting groove 114 on the side wall of the shell body 110 facing the mounting leg 120, and mounting the mounting leg 120 to the second mounting groove 114, the height of the mounting leg 120 protruding from the side wall of the shell body 110 where the second mounting groove 114 is provided can be reduced. This reduces the possibility that the mounting leg 120 will be hit due to protruding from the shell body 110 during the use of the shell assembly 100, and ensures the assembly reliability of the mounting leg 120 and the shell body 110.

[0108] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
