Description

Technical Field

[0001] The present application relates to the technical field of electrical components and equipment, and in particular to a housing assembly and a switch device. Background Art

[0002] Switchgear is an indispensable part of the power system. Switchgear can protect electrical equipment by controlling the on and off of the circuit. Switchgear can be circuit breakers, contactors, etc.

[0003] The switchgear generally includes a housing, which is directly or indirectly connected to the switchgear. However, based on the structure of the existing housing, the volume of the housing is relatively large, which in turn makes the manufacturing cost of the switchgear relatively high. Utility Model Content

[0004] The present application provides a housing assembly and a switch device, which can reduce the structure of the housing and lower the manufacturing cost of the switch device.

[0005] In a first aspect, the present application provides a housing assembly, the housing assembly comprising a housing body and a slider. A mounting groove is provided on one side of the housing body. The slider comprises a slider body and a fixing portion, the slider body is installed in the mounting groove, the fixing portion is provided with a first mounting hole, and part of the first connecting member is passed through the first mounting hole to connect the housing assembly with an external component. Along the direction from the housing body to the slider, the projection of the fixing portion is outside the projection range of the housing body.

[0006] In the example of the present application, the shell body can provide a mounting carrier for the slider. Since the slider body is a part of the slider, the mounting groove is provided in the shell body, and the slider body is installed in the mounting groove, the connection between the slider and the shell body can be achieved through the connection between the slider body and the mounting groove. Since the fixing portion is a part of the slider, the first mounting hole is provided in the fixing portion, and the first connecting member is provided in the first mounting hole to achieve the connection between the slider and the external component. Since the shell body is connected to the slider, the shell body can be connected to the external component through the slider and the first connecting member.

[0007] Since the projection of the fixing portion from the shell body to the slider is outside the projection range of the shell body, the possibility of interference between the first connecting member and the shell body can be reduced when the first connecting member is inserted into the first mounting hole to connect the slider and the external component.

[0008] In addition, compared with the prior art in which two protrusions are arranged at intervals on the base, and the connection between the base and the external component is achieved by setting a threaded hole on each protrusion, in the example of the present application, the first mounting hole is set on the slider, which can reduce the number of threaded holes set on the shell body, thereby reducing the protrusions set on the shell body and reducing the volume of the shell body. During the transportation and use of the contactor, the possibility of collision between the shell body and other structural parts, thereby causing damage to the shell body, is reduced, thereby ensuring the reliability of the contactor.

[0009] In some possible implementations, the slider further includes a bending portion, which is disposed on a side of the fixing portion away from the slider body, and is bent along the fixing portion toward the external component.

[0010] In the case where the first connecting member is passed through the first mounting hole, since the first mounting hole is provided in the fixing portion, the first connecting member can apply a force to the fixing portion through the first mounting hole. Since the bending portion is connected to the fixing portion, the fixing portion can drive the bending portion so that the bending portion abuts against the external component. The external component can apply a reaction force to the bending portion, thereby making the contact between the slider and the external component closer and reducing the amplitude of the shaking of the slider relative to the external component.

[0011] In some possible implementations, the slider further includes an extension portion. The extension portion is connected to a side of the bent portion away from the fixed portion, and the extension portion extends along the bent portion toward the mounting groove, the extension portion is provided with a second mounting hole, the first connecting member can be inserted through the first mounting hole and the second mounting hole to connect the housing assembly and the external component, and the extension portion is in surface contact with the external component.

[0012] In the example of the present application, the slider is provided with a bending portion and an extending portion, the bending portion is bent along the direction of the fixed portion away from the shell body, the extending portion extends along the bending portion toward the mounting groove, and the extending portion is provided with a second mounting hole. Based on this, when the first connecting member is inserted into the first mounting hole and the second mounting hole, the first connecting member can apply a force to the fixed portion through the first mounting hole. Since the bending portion is connected to the fixed portion, and the extending portion is connected to the bending portion, the fixed portion can drive the bending portion and the extending portion to have a tendency to move toward the external component, thereby making the extending portion contact with the surface of the external component. The external component can apply a reaction force to the extending portion, so that the contact between the slider and the external component is closer, further reducing the amplitude of the slider shaking relative to the external component.

[0013] In some possible implementations, the slider further includes a support portion, one end of which is connected to an end of the extension portion away from the bending portion, and the other end of the support portion can abut against the slider body. Alternatively, the other end of the support portion can abut against the fixing portion.

[0014] In the case where the first connecting member is passed through the slider to connect the slider and the external component, the first connecting member can apply a force to the slider toward the external component, and the external component can apply a reaction force to the slider, so that the support portion abuts against the slider body, thereby reducing the amplitude of the mutual shaking between the first connecting member, the slider and the external component, and further ensuring the connection reliability among the first connecting member, the slider and the external component.

[0015] In some possible implementations, the fixing portion is further provided with a first disassembly hole, and the first disassembly hole is provided on a side of the first mounting hole away from the slider body.

[0016] In the example of the present application, by setting a first disassembly hole, the operator can insert the disassembly tool into the first disassembly hole, thereby facilitating the operator to apply a force to the slider along the assembly direction of the slider away from the shell body during the disassembly work, thereby improving the efficiency of separating the slider from the external component.

[0017] In some possible implementations, the first disassembly hole and the first installation hole are spaced apart from each other, or the first disassembly hole is connected to the first installation hole.

[0018] In some possible implementations, the extension portion is further provided with a second disassembly hole, and the second disassembly hole is provided on a side of the second mounting hole away from the slider body.

[0019] In some possible implementations, a groove wall of the installation groove is provided with a limiting groove, and the slider further includes a limiting portion, at least a portion of the limiting portion extends into the limiting groove to limit the slider and the shell body.

[0020] Since the limiting groove is arranged on the groove wall of the installation groove, the installation groove is arranged on the shell body, and the limiting portion is arranged on the slider, the slider and the shell body can be matched through the matching of the limiting portion and the limiting groove.

[0021] In some possible implementations, a first connection structure is provided on the side of the slider body away from the fixing portion, and the first connection structure is spaced apart from the limiting portion. A second connection structure is provided on the shell body, and the second connection structure is spaced apart from the limiting groove, and the first connection structure cooperates with the second connection structure.

[0022] Since the first connection structure and the limiting component are spaced apart, and the second connection structure and the limiting groove are spaced apart, the first connection structure and the second connection structure can cooperate to limit the slider and the shell body at a position different from the position where the limiting part and the limiting groove cooperate, further ensuring the connection reliability between the shell body and the slider.

[0023] In a second aspect, the present application provides a switch device, comprising a contact mechanism and a housing assembly in any of the above possible implementations. The housing assembly is provided with a receiving cavity, and the contact mechanism is provided in the receiving cavity.

[0024] The beneficial effects of the shell assembly provided in the above-mentioned second aspect and each possible design of the above-mentioned second aspect can be referred to the beneficial effects brought about by the above-mentioned first aspect and each possible implementation manner of the first aspect, and will not be repeated here.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the examples of this application clearer, the technical solution in the examples of this application will be clearly and completely described below in conjunction with the drawings in the examples of this application. Obviously, the described examples are part of the examples of this application, not all of them. Based on the examples in this application, all other examples obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of the application herein are only for the purpose of describing specific examples and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover non-exclusive inclusions.

[0035] Reference to "examples" herein means that a particular feature, structure, or characteristic described in conjunction with the examples may be included in at least one example of the present application. The appearance of the phrase "example" in various locations in the specification does not necessarily refer to the same example, nor is it an independent or alternative example that is mutually exclusive with other examples. It is explicitly and implicitly understood by those skilled in the art that the examples described herein may be combined with other examples.

[0036] The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists, A and B exist at the same time, and B exists. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0037] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the housing assembly and the switch device of the present application.

[0038] In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned 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.

[0039] In the description of the present application, unless otherwise specified, "plurality" means more than two (including two), and similarly, "multiple groups" means more than two groups (including two).

[0040] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure may refer to a physical connection. For example, the physical connection may be a fixed connection, such as a fixed connection through a barrier, such as a fixed connection through screws, bolts or other barrier; the physical connection may also be a detachable connection, such as a mutual snap-on or snap-fit ​​connection; the physical connection may also be an integral connection, such as a connection formed by welding, bonding or integral molding. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] Switchgear is an electrical component that protects the circuit. Switchgear can be a contactor, circuit breaker or other electrical component that can control the on and off of the circuit.

[0042] Taking the contactor as an example, the contactor can control the start and stop of the motor or other load by controlling the connection and disconnection of the circuit. The contactor can also protect the load when the circuit is overloaded.

[0043] The contactor generally includes a housing assembly. The contactor can be directly connected to the power distribution system through the housing assembly. This application only describes the example of the contactor being connected to the power distribution cabinet through the housing assembly.

[0044] The housing assembly usually includes a base. In the prior art, two protrusions are usually spaced apart on the base, each protrusion is provided with a mounting hole, and a connector can be passed through the mounting hole to connect the base and the distribution cabinet.

[0045] Based on the structure of the existing base, the protrusion is protruding from the base, which increases the volume of the base and thus increases the manufacturing cost of the base. In addition, since the protrusion is protruding from the base, it is easy to collide with the protrusion during the transportation and use of the contactor, thereby causing damage to the base and affecting the performance of the contactor.

[0046] Based on the above, the present application example provides a housing assembly and a switch device.

[0047] In order to enable persons skilled in the art to better understand the present application, the housing assembly and switch device provided in the example of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0048] Exemplarily, the present application provides a switch device, which may include a contact mechanism and a housing assembly. The housing assembly is provided with a receiving cavity, and the contact mechanism is provided in the receiving cavity.

[0049] The switch device may be an electrical device such as a contactor or a circuit breaker that can control the on and off of a circuit. This application example is described only by taking the switch device being a contactor as an example.

[0050] In the example of this application, the external component can be a power distribution cabinet, a guide rail or other structure. For example, the contactor can be directly connected to the power distribution cabinet or other panel structure through a connector, and the contactor can also be connected to the guide rail through a slider, and the guide rail can be fixedly installed on the power distribution cabinet. Different external components can be selected according to customer needs or the use environment of the contactor.

[0051] The contactor may include a contact mechanism and a housing assembly. The housing assembly may be provided with an accommodating cavity, and the contact mechanism may be installed in the accommodating cavity.

[0052] The contact mechanism may include a moving contact and a stationary contact that match each other. When the moving contact and the stationary contact are in contact, the contactor is in an operating state, and current flows through the circuit. When the moving contact and the stationary contact are separated, the contactor is in a released state, and no current flows through the circuit.

[0053] The other structures of the contactor are similar to other structures in the prior art, and will not be described in detail in this application example.

[0054] Next, the structure of the housing assembly is described in detail.

[0055] Exemplarily, the present application provides a housing assembly. Figure 1 A schematic diagram of the structure of a housing assembly provided for this application example, Figure 2 A schematic diagram of the structure of a shell body is provided for the example of this application. Figure 3 A schematic diagram of the structure of a slider provided as an example of this application.

[0056] Please refer to Figure 1 to Figure 3 The housing assembly may include a housing body 100 and a slider 200. A mounting groove 110 is provided on one side of the housing body 100. The slider 200 may include a slider body 220 and a fixing portion 210. The slider body 220 is installed in the mounting groove 110. The fixing portion 210 is provided with a first mounting hole 211. Part of the first connecting member is passed through the first mounting hole 211 to connect the housing assembly with an external component. Along the direction from the housing body 100 to the slider 200, the projection of the fixing portion 210 is outside the projection range of the housing body 100.

[0057] The shell body 100 can be formed by combining multiple parts, or the shell body 100 can be integrally formed. This application example is only described as the shell body 100 being formed by combining multiple parts.

[0058] The shell body 100 may include a base, a middle base, an upper cover and other structures. The base, the middle base and the upper cover and other structures may cooperate to form a receiving cavity to provide installation space for components such as contact mechanisms.

[0059] The shell body 100 can be made of insulating material, such as phenolic molding compound among thermosetting plastics, polyhexamethylene adipamide, PA6 nylon plastic and the like among thermoplastic plastics.

[0060] The shell body 100 made of insulating material can reduce the possibility of leakage of current in the shell body 100 and ensure the safety of the contactor.

[0061] The base may include a protrusion 140, the protrusion 140 is provided with at least one through hole, and the protrusion 140 is spaced apart from the slider 200. A connector may be inserted through the through hole to achieve connection between the base and the external component.

[0062] The mounting groove 110 may be disposed on the outer bottom wall of the shell body 100 , and specifically may be disposed on a side of the base away from the middle seat.

[0063] The slider 200 may include a slider body 220 and a fixing portion 210. The slider body 220 may be matched with the mounting groove 110. The slider body 220 may be detachably connected to the groove wall of the mounting groove 110 by snapping or other means.

[0064] Exemplarily, a snap-fit ​​protrusion may be provided on the slider body 220 , and a snap-fit ​​groove may be provided on the bottom wall of the shell body 100 . The snap-fit ​​protrusion is snap-fitted with the snap-fit ​​groove to realize the connection between the slider body 220 and the shell body 100 .

[0065] Exemplarily, a snap-fit ​​groove may be provided on the slider body 220 , and a snap-fit ​​protrusion may be provided on the bottom wall of the shell body 100 . The snap-fit ​​protrusion cooperates with the snap-fit ​​groove to realize the connection between the slider body 220 and the shell body 100 .

[0066] Exemplarily, a snap-fit ​​groove may be provided on the groove wall of the installation groove 110 , and a portion of the slider body 220 may extend into the snap-fit ​​groove to achieve connection between the slider body 220 and the shell body 100 .

[0067] The fixing portion 210 may be provided with a first mounting hole 211 , and part of the first connecting member may be passed through the first mounting hole 211 to connect the housing assembly with the external component.

[0068] The first connecting member may be a bolt, a screw, a rivet, etc. At this time, the external component may be a power distribution cabinet or other panel structures.

[0069] The first mounting hole 211 can be a plain hole, a threaded hole or other hole. The first mounting hole 211 can be a round hole, a square hole or a hole of other shapes, as long as the first connecting member can pass through the first mounting hole 211 and be installed in the fixing part 210 .

[0070] When the external component is a power distribution cabinet, the power distribution cabinet can be provided with a fourth mounting hole, and part of the first connecting member can be passed through the first mounting hole 211 and the fourth mounting hole. Since the fourth mounting hole is provided in the power distribution cabinet, the first mounting hole 211 is provided in the fixing portion 210, and the fixing portion 210 is part of the slider 200. Therefore, the first connecting member passing through the first mounting hole 211 and the fourth mounting hole can realize the connection between the slider 200 and the power distribution cabinet.

[0071] In the implementation of the present application, the projection of the fixing portion 210 can be located outside the projection range of the shell body 100 by setting the fixing portion 210 to extend out of the slider 200, or by setting a groove on the shell body 100, in which the fixing portion 210 is arranged. Of course, the projection of the fixing portion 210 can also be located outside the projection range of the shell body 100 by other methods.

[0072] Based on this, when the first connecting member is inserted into the first mounting hole 211, the possibility of interference between the first connecting member and the shell body 100 can be reduced, thereby improving the connection reliability and connection efficiency of the shell body 100, the slider 200 and the first connecting member.

[0073] In summary, in the example of the present application, the shell body 100 can provide a mounting carrier for the slider 200. Since the slider body 220 is a part of the slider 200, the mounting groove 110 is provided in the shell body 100, and the slider body 220 is installed in the mounting groove 110, the connection between the slider 200 and the shell body 100 can be achieved through the connection between the slider body 220 and the mounting groove 110. Since the fixing portion 210 is a part of the slider 200, the first mounting hole 211 is provided in the fixing portion 210, and the first connecting member is provided in the first mounting hole 211, so that the connection between the slider 200 and the external component can be achieved. Since the shell body 100 is connected to the slider 200, the shell body 100 can be connected to the external component through the slider 200 and the first connecting member.

[0074] Since the projection of the fixing portion 210 is outside the projection range of the shell body 100 along the direction from the shell body 100 to the slider 200, the possibility of interference between the first connecting member and the shell body 100 can be reduced when the first connecting member is passed through the first mounting hole 211 to connect the slider 200 and the external component.

[0075] In addition, compared with the prior art in which two protrusions are arranged on the base in a relative manner, and the connection between the base and the external component is achieved by setting a mounting hole on each protrusion, in the example of the present application, the first mounting hole 211 is set on the slider 200, which can reduce the number of threaded holes set on the shell body 100, thereby reducing the protrusion 140 set on the shell body 100, so as to reduce the volume of the shell body 100. During the transportation and use of the contactor, the possibility of collision between the shell body 100 and other structural parts, thereby causing damage to the shell body 100, is reduced, and the reliability of the contactor is ensured.

[0076] Based on the shell assembly provided in the above example, along the direction from the shell body 100 to the slider 200, the size of the slider 200 can be equal to the size of the protrusion 140, and the size of the slider 200 can also be smaller than the size of the protrusion 140, that is, the thickness of the slider 200 can be equal to the thickness of the protrusion 140, and the thickness of the slider 200 can also be smaller than the thickness of the protrusion 140.

[0077] Based on the housing assembly provided in the above example, Figure 4 For a structural diagram of a slider first-person perspective provided for this application example, please refer to Figure 4 When the thickness of the slider 200 is less than the thickness of the protrusion 140, the slider 200 may further include a bending portion 230. The bending portion 230 may be disposed on a side of the fixing portion 210 away from the slider body 220. The bending portion 230 may be bent along the fixing portion 210 toward the external component.

[0078] An end of the extending portion 240 away from the fixing portion 210 may be in contact with the external component, or there may be a gap between the extending portion 240 and the external component.

[0079] Along the direction from the housing body 100 to the slider 200, the size of the bent portion 230 may be substantially equal to the size of the extension portion 240, that is, the length of the bent portion 230 may be substantially equal to the thickness of the extension portion 240. Here, the size of the bent portion 230 being substantially equal to the size of the extension portion 240 means that the difference between the size of the bent portion 230 and the size of the extension portion 240 is within 3 mm.

[0080] Based on this, the length of the first connecting member passing through the first mounting hole 211 can be equal to the length of the connecting member passing through the third mounting hole 141. When the diameters of the first mounting hole 211 and the third mounting hole 141 are the same, the specifications of the first connecting member can be the same as the specifications of the connecting member, which facilitates the operator to complete the assembly of the shell body 100, the slider 200 and the external components.

[0081] Based on the above, in the case where the first connecting member is passed through the first mounting hole 211, since the first mounting hole 211 is provided in the fixing portion 210, the first connecting member can apply a force to the fixing portion 210 through the first mounting hole 211, and since the bending portion 230 is connected to the fixing portion 210, the fixing portion 210 can drive the bending portion 230 so that the bending portion 230 abuts against the external component, and the external component can apply a reaction force to the bending portion 230, so that the contact between the slider 200 and the external component is closer, thereby reducing the amplitude of the shaking of the slider 200 relative to the external component.

[0082] Based on the housing assembly provided in the above example, Figure 5 For a structural diagram of a slider second perspective provided for this application example, please refer to Figure 4 and Figure 5 The slider 200 may further include an extension portion 240. The extension portion 240 may be connected to a side of the bending portion 230 away from the fixing portion 210, and the extension portion 240 may extend along the bending portion 230 toward the mounting groove 110. The extension portion 240 is provided with a second mounting hole 241. The first connecting member may be inserted through the first mounting hole 211 and the second mounting hole 241 to connect the housing assembly with the external component, and the extension portion 240 is in surface contact with the external component.

[0083] The shape of the extension portion 240 can be completely the same as that of the fixed portion 210. Along the direction from the extension portion 240 to the fixed portion 210, the area of ​​the extension portion 240 can be equal to the area of ​​the fixed portion 210, the area of ​​the extension portion 240 can also be smaller than the area of ​​the fixed portion 210, and the area of ​​the extension portion 240 can also be larger than the area of ​​the fixed portion 210, as long as it is ensured that along the direction from the bending portion 230 to the slider body 220, the size of the extension portion 240 is larger than the distance between the first mounting hole 211 and the bending portion 230, so that the extension portion 240 can provide the second mounting hole 241 with a setting position that can meet the first connection member passing through the first mounting hole 211 and the second mounting hole 241.

[0084] The second mounting hole 241 and the first mounting hole 211 can be arranged concentrically, and the center line of the second mounting hole 241 and the center line of the first mounting hole 211 may not coincide, as long as the first connecting member can be passed through the first mounting hole 211 and the second mounting hole 241 to realize the connection between the slider 200 and the external component.

[0085] Based on the above, in the example of the present application, the slider 200 is provided with a bending portion 230 and an extension portion 240. The bending portion 230 is bent along the direction of the fixing portion 210 away from the shell body 100, and the extension portion 240 extends along the bending portion 230 toward the mounting groove 110. The extension portion 240 is provided with a second mounting hole 241. Based on this, when the first connecting member is inserted into the first mounting hole 211 and the second mounting hole 241, the first connecting member can apply a force to the fixing portion 210 through the first mounting hole 211. Since the bending portion 230 is connected to the fixing portion 210, and the extension portion 240 is connected to the bending portion 230, the fixing portion 210 can drive the bending portion 230 and the extension portion 240 to have a tendency to move toward the external component, thereby making the extension portion 240 in surface contact with the external component. The external component can apply a reaction force to the extension portion 240, so that the contact between the slider 200 and the external component is closer, further reducing the amplitude of the slider 200 shaking relative to the external component.

[0086] In addition, compared with setting the thickness of the fixing portion 210 equal to the thickness of the protrusion 140, in the example of the present application, the length of the bending portion 230 can be set to be basically equal to the thickness of the protrusion 140, which can reduce the material used for the slider 200 and thereby reduce the manufacturing cost of the slider 200.

[0087] Based on the above example, please refer to the housing assembly provided Figure 4 and Figure 5 The slider 200 may further include a support portion 250, one end of which may be connected to an end of the extension portion 240 away from the bending portion 230, and the other end of the support portion 250 may abut against the slider body 220. Alternatively, the other end of the support portion 250 may abut against the fixing portion 210.

[0088] In the case where the area of ​​the extension portion 240 is smaller than the area of ​​the fixing portion 210, the support portion 250 may abut against the fixing portion 210, or the support portion 250 may abut against the fixing portion 210 and the slider body 220. In the case where the area of ​​the extension portion 240 is greater than or equal to the area of ​​the fixing portion 210, the support portion 250 may abut against the slider body 220. The present application example is described only by taking the example of the support portion 250 abutting against the slider body 220.

[0089] In the case where the first connecting member is not disposed through the slider 200 , the support portion 250 may be in contact with the slider body 220 , or there may be a gap between the support portion 250 and the slider body 220 .

[0090] When the first connecting member is passed through the slider 200 to connect the slider 200 and the external component, the first connecting member can apply a force to the slider 200 toward the external component, and the external component can apply a reaction force to the slider 200, so that the support portion 250 abuts against the slider body 220, thereby reducing the amplitude of the mutual shaking between the first connecting member, the slider 200 and the external component, and further ensuring the connection reliability between the first connecting member, the slider 200 and the external component.

[0091] Based on the housing assembly provided in the above example, Figure 6 for Figure 2 Please refer to the partial enlarged schematic diagram of point Ⅰ in the middle. Figure 1 and Figure 6 The groove wall of the installation groove 110 is provided with a limiting groove 111, and the slider 200 may also include a limiting portion, at least part of which extends into the limiting groove 111 to limit the slider 200 and the shell body 100.

[0092] The limiting portion may include a first limiting structure and a second limiting structure. At least part of the first limiting structure may be disposed on one side of the slider body 220 , and at least part of the second limiting structure may be disposed on the other side of the slider body 220 .

[0093] The limiting groove 111 may include a first limiting groove and a second limiting groove. The first limiting groove may be provided on one groove wall of the installation groove 110 , and the second limiting groove may be provided on another groove wall of the installation groove 110 .

[0094] When the slider 200 is matched with the shell body 100, the first limiting structure can extend into the first limiting groove, and the second limiting structure can extend into the second limiting groove. The connection between the slider 200 and the shell body 100 can be achieved through the cooperation between the first limiting groove and the first limiting structure, and the cooperation between the second limiting groove and the second limiting part.

[0095] The shell body 100 may also include a reinforcement portion 130, which is protruding from the shell body 100. The reinforcement portion 130 is spaced apart from the protrusion 140, and the extension direction of the reinforcement portion 130 is opposite to the extension direction of the protrusion 140. Part of the limiting groove 111 can be provided in the reinforcement portion 130, and part of the limiting portion can be provided in the fixing portion 210. The limiting groove 111 provided in the reinforcement portion 130 is similar to the limiting groove 111 provided in the groove wall of the installation groove 110, and the limiting portion provided in the fixing portion 210 is similar to the limiting portion provided in the slider body 220, and the example of this application is not described in detail here.

[0096] In summary, since the limiting groove 111 is provided on the groove wall of the installation groove 110 , the installation groove 110 is provided on the shell body 100 , and the limiting portion is provided on the slider 200 , the slider 200 can cooperate with the shell body 100 through the cooperation of the limiting portion and the limiting groove 111 .

[0097] Based on the above example, please refer to the housing assembly provided Figure 3 and Figure 6 The slider body 220 is provided with a first connection structure 221 on one side away from the fixing portion 210, and the first connection structure 221 is spaced apart from the limiting portion. The shell body 100 is provided with a second connection structure 120, and the second connection structure 120 is spaced apart from the limiting groove 111, and the first connection structure 221 cooperates with the second connection structure 120.

[0098] The first connection structure may be a snap-in groove, and the second connection structure may be a snap-in protrusion. Alternatively, the first connection structure 221 may be a snap-in protrusion, and the second connection structure 120 may be a snap-in groove. Alternatively, the first connection structure 221 and the second connection structure 120 may also be other structures, as long as the first connection structure 221 and the second connection structure 120 cooperate to realize the detachable connection between the slider 200 and the shell body 100, and when the operator separates the slider 200 and the shell body 100 using a detachable tool, the slider 200 can be separated from the shell body 100.

[0099] Based on the above, since the first connecting structure 221 and the limiting component are spaced apart, and the second connecting structure 120 and the limiting groove 111 are spaced apart, the first connecting structure 221 and the second connecting structure 120 can cooperate with each other to limit the slider 200 and the shell body 100 at a position different from the position where the limiting part and the limiting groove 111 cooperate, thereby further ensuring the connection reliability between the shell body 100 and the slider 200.
