Description

Technical Field

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

[0002] Contactor is a widely used switching device with the advantages of strong current breaking capacity, fast action, safe operation, frequent operation and remote control.

[0003] In the prior art, since the contact support is provided in the base of the contactor, a reaction spring for supporting the contact support is provided in the base of the contactor. When the base and the base are connected to each other, the reaction spring will generate a force on the base to make the base move away from the base, or the reaction spring will generate a force on the base to make the base move away from the base, which makes it difficult to install and remove the bases. Utility Model Content

[0004] The present application provides a housing assembly and a contactor to reduce the difficulty of installing and disassembling between a base and a pedestal of the contactor.

[0005] In a first aspect, the present application provides a shell assembly, including a base, a pedestal, and a first elastic member. The base is provided with a connecting structure. A matching structure is provided at a position opposite to the connecting structure, and the matching structure is adapted to the connecting structure. The first end of the first elastic member abuts against the base, and the second end of the first elastic member abuts against the pedestal. The first elastic member is in a compressed state, and the base and / or the pedestal overcome the elastic force of the first elastic member, and are connected by the connecting structure and the matching structure, so that the base and the pedestal are connected.

[0006] Through the above scheme, the present application sets a connection structure on the base, and sets a matching structure on the base that matches the connection structure. When the base and the base are in a covered state, the connection structure and the matching structure are snapped together, which, on the one hand, reduces the difficulty of installing the base and the base, making the subsequent installation process of the base and the base simpler, and because the connection structure and the matching structure are in a snapped state, when the base and the base are separated, the base and the base will not be quickly separated under the action of the elastic force of the first elastic member.

[0007] On the other hand, the connection between the connecting structure and the matching structure can also improve the installation tolerance between the base and the pedestal. After the connection structure and the matching structure are connected, the relative position of the base and the pedestal can be fine-tuned to make the installation between the base and the pedestal more accurate.

[0008] In a possible design, the connection structure is a limit groove, the matching structure is a limit block, and the connection structure and the matching structure are interference fit. Alternatively, the connection structure is a limit block, the matching structure is a limit groove, and the connection structure and the matching structure are interference fit.

[0009] Through the above solution, when the base and the pedestal are covered, the limit block is inserted into the limit groove, so that the connection structure and the matching structure can be connected by interference fit. Through this arrangement, the installation of the base and the pedestal is easier, and the connection structure and the matching structure can be connected by just plugging or pulling.

[0010] In a possible design, the connection structure is an elastic block, the matching structure is a slot, and the connection structure and the matching structure are elastically connected. Alternatively, the connection structure is a slot, the matching structure is an elastic block, and the connection structure and the matching structure are elastically connected.

[0011] Through the above scheme, in the process of covering the base with the pedestal, the elastic card block is squeezed and deformed. When the base or the pedestal moves to make the elastic card block relative to the card slot, the elastic card block resumes its deformation. At this time, the elastic card block is engaged in the card slot. The deformable characteristic of the elastic card block is utilized to enable the connecting structure and the matching structure to complete elastic engagement. When the connecting structure and the matching structure need to be separated, the connecting structure and the matching structure can be separated by the deformation of the elastic card block.

[0012] In a possible design, the elastic card block includes a connecting portion and a clamping portion connected to each other, and the clamping portion protrudes relative to the connecting portion. When the connecting structure is an elastic card block, the base is provided with a first mounting groove, and the connecting portion is connected to the groove wall of the first mounting groove. When the matching structure is an elastic card block, the base is provided with a second mounting groove, and the connecting portion is connected to the groove wall of the second mounting groove.

[0013] Through the above scheme, the elastic card block is formed by the connecting part and the clamping part, which can increase the diversity of the types of elastic card blocks. The clamping part is set to protrude from the connecting part so that the clamping part can be more effectively clamped with the matching structure. The first installation groove is set on the base or the second installation groove is set on the base, which can not only position the installation position of the elastic card block, but also make the installation of the elastic card block easier.

[0014] In a possible design, when the connecting structure is an elastic block, there is a first gap between the connecting structure and the first installation slot. When the matching structure is an elastic block, there is a second gap between the matching structure and the second installation slot.

[0015] Through the above scheme, when the connecting structure is an elastic card block, a first gap is reserved between the connecting structure and the first mounting groove, or, when the mating structure is an elastic card block, a second gap is reserved between the mating structure and the second mounting groove. When the connecting structure and the mating structure are separated, a tool can be inserted into the first gap or the second gap to assist in separating the connecting structure and the mating structure, thereby reducing the difficulty of installation between the base and the pedestal.

[0016] In a possible design, the connecting portion is a connecting rod, or the connecting portion is a second elastic member.

[0017] Through the above solution, when the connecting part is set as a connecting rod, the connecting part has the advantages of easy manufacturing and low cost. When the connecting part is set as a second elastic member, the connecting part can be a spring or a spring sheet, etc. This increases the diversity of the selection of the connecting part, and a suitable connecting part can be selected for use according to actual manufacturing requirements.

[0018] In a possible design, the base is provided with a first mounting hole, and the pedestal is provided with a second mounting hole. When the matching structure is a slot, the slot passes through the pedestal along a first direction, and the first direction is perpendicular to the mounting direction of the pedestal and the pedestal. When the connecting structure is a slot, the slot passes through the pedestal along the first direction. The base and / or the pedestal can be moved along the first direction so that the positions of the first mounting hole and the second mounting hole are opposite, and the first mounting hole and the second mounting hole are used for fasteners to pass through.

[0019] Through the above scheme, a first mounting hole is set on the base, and a second mounting hole is set on the pedestal. The fastener passes through the first mounting hole and the second mounting hole to fix the base and the pedestal. In this way, in addition to the connection between the base and the pedestal by the connection structure and the matching structure being engaged with each other, the base and the pedestal are fixed by fasteners, which can further improve the connection reliability between the base and the pedestal, and reduce the possibility of separation between the base and the pedestal when the contactor is bumped or dropped. Compared with the related art in which the base and the pedestal are fixed by fasteners while the base and / or the pedestal overcome the elastic force of the first elastic member, the present application reduces the time cost and labor cost required in the installation process of the base and the pedestal, and improves the safety of the base and the pedestal during the disassembly process.

[0020] Furthermore, a card slot is provided that passes through the base along the first direction, or a card slot is provided that passes through the base along the first direction, so that the tolerance for installation between the bases can be increased. After the connecting structure is connected with the card slot, if the positions of the first mounting hole and the second mounting hole are not aligned, the position of the base or the base can be adjusted along the card slot that passes through the base along the first direction, or the card slot that passes through the base along the first direction, until the first mounting hole is aligned with the second mounting hole, and then fastened with fasteners.

[0021] In a possible design, there are multiple elastic card blocks, and the multiple elastic card blocks are arranged at intervals along a first direction. The multiple elastic card blocks are all engaged with the card slots, and the first direction is perpendicular to the installation direction of the base and the pedestal.

[0022] Through the above solution, multiple elastic card blocks are arranged to be connected with the card slots. On the one hand, the elastic force of the first elastic member can be overcome more easily, ensuring that the base and the base cover will not be easily separated after being closed. On the other hand, when one elastic card block is damaged, the remaining elastic card blocks can still be effectively connected with the card slots, thereby increasing the service life of the shell assembly and reducing the maintenance cost of the shell assembly in the later stage.

[0023] In a possible design, a side of the connecting structure facing the matching structure is provided with an arc chamfer.

[0024] Through the above scheme, an arc chamfer is set on the side of the connecting structure facing the mating structure, or an arc chamfer is set on the side of the mating structure facing the connecting structure, or an arc chamfer is set on the side of the connecting structure opposite to the mating structure. This not only makes the connection and disassembly process between the connecting structure and the mating structure smoother, but the arc chamfer can also guide the mating structure, thereby reducing the difficulty of installation between the base and the pedestal.

[0025] In a second aspect, the present application provides a contactor, comprising a contact support and a housing assembly according to the first aspect, wherein the contact support is disposed in the housing assembly, the second end of the first elastic member abuts against one end of the contact support, and part of the contact support abuts against the base.

[0026] Through the above scheme, the installation difficulty between the base and the pedestal is reduced, making the subsequent installation process of the base and the pedestal simpler, and because the connecting structure and the matching structure are in a snap-connected state, when the base and the pedestal are disassembled, the base and the pedestal will not be quickly separated under the action of the elastic force of the first elastic member.

[0027] The beneficial effects of the contactor provided in the second aspect can be referred to the beneficial effects brought about by the first aspect and the possible implementation methods of the first aspect, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0052] An embodiment of the present application provides a contactor, which includes a contact support and a housing assembly. The contact support is arranged in the housing assembly, the second end of the first elastic member abuts against one end of the contact support, and part of the contact support abuts against the base.

[0053] A contactor is an automatic electrical device used to frequently connect and disconnect AC and DC main circuits and control circuits over a long distance. The main control object is the motor, and it can also be used for other power loads, such as electric furnaces and electric welders. Contactors have the advantages of undervoltage protection, zero voltage protection, large control capacity, reliable operation, and long service life.

[0054] The contact support is one of the important components inside the contactor. The moving contact of the contactor is installed on the contact support, and the contact support is movably installed in the housing assembly. The contact support moves under the action of the electromagnet, so that the moving contact contacts or separates with the static contact.

[0055] The shell assembly includes a base, a pedestal, a first elastic member and a contact support. The base and the pedestal cover form an installation space. The first elastic member and the contact support are both arranged in the installation space. One end of the first elastic member abuts the base, and the other end of the first elastic member abuts the contact support. Part of the contact support abuts against the inner top surface of the pedestal.

[0056] In the prior art, the bases are fixedly connected with each other by bolts. Due to the presence of the first elastic member, when the bases are installed or disassembled, the first elastic member will exert a force on the bases and / or the bases to move them away from each other, making installation and disassembly between the bases difficult.

[0057] Based on this, the present application improves the structure of the shell assembly in order to reduce the difficulty of installation and disassembly between the base and the pedestal.

[0058] The housing assembly provided in the present application is explained in detail below with reference to the accompanying drawings.

[0059] Figure 1 A schematic diagram of a portion of the structure of a contactor provided in an embodiment of the present application at a certain viewing angle. Figure 2 A schematic diagram of a portion of the structure of the contactor provided in an embodiment of the present application from another perspective. Figure 3 An exploded view of a portion of the structure of a contactor provided in an embodiment of the present application.

[0060] like Figures 1 to 3 As shown, the present application provides a shell assembly, including a base 100, a base 200 and a first elastic member 300. The base 100 is provided with a connecting structure 110. A matching structure 210 is provided at a position of the base 200 opposite to the connecting structure 110, and the matching structure 210 is adapted to the connecting structure 110. The first end of the first elastic member 300 abuts against the base 100, and the second end of the first elastic member 300 abuts against the base 200. The first elastic member 300 is in a compressed state, and the base 100 and / or the base 200 overcome the elastic force of the first elastic member 300, and are clamped by the connecting structure 110 and the matching structure 210, so that the base 100 and the base 200 are connected.

[0061] The base 100 is provided with an installation space inside, and a mounting portion 130 is provided in the installation space of the base 100. The mounting portion 130 may be a mounting column or a mounting groove, etc. The mounting portion 130 is used to mount the first elastic member 300. The first end of the first elastic member 300 abuts against the base 100, which means that the first elastic member 300 is mounted on the mounting portion 130 of the base 100, and the second end of the first elastic member 300 abuts against the base 200, which means that the second end of the first elastic member 300 abuts against one end of the contact support 500, and part of the contact support 500 abuts against the inner top surface of the base 200.

[0062] It should be noted that the mounting portion 130 inside the base 100 can be selected according to the shape of the first elastic member 300. For example, when the first elastic member 300 is a spring, the mounting portion 130 can be a mounting column; when the first elastic member 300 is a spring, the mounting portion 130 can be a mounting groove.

[0063] The base 200 can be made of the same material as the base 100, or can be made of a different material from the base 100. An installation space is provided inside the base 200, and a through hole is provided on the wall of the base 200 away from the base 100, through which one end of the contact support 500 extends to the outside of the base 200.

[0064] The first elastic member 300 may be a spring or a spring sheet, etc. The first elastic member 300 may be made of a metal material, or may be made of a plastic material.

[0065] The connection structure 110 may be a connection member provided on the base 100. The connection structure 110 may be integrally formed with the base 100 when the base 100 is formed, or the connection structure 110 may be separately formed from the base 100 and then assembled, or the connection structure 110 may be provided on the base 100 by cutting, engraving, or the like after the base 100 is formed.

[0066] The matching structure 210 may be a connecting member provided on the base 200. The matching structure 210 may be integrally formed with the base 200 when the base 200 is formed, or the matching structure 210 may be separately formed with the base 200 and then assembled, or the matching structure 210 may be provided on the base 200 by cutting, engraving, or other processes after the base 200 is formed.

[0067] When the base 100 and the base 200 are covered, the first elastic member 300 is converted from a normal state to a compressed state. When the base 100 and the base 200 are separated, the first elastic member 300 is converted from a compressed state to a normal state.

[0068] When the base 100 and the base 200 are covered, the first elastic member 300 generates a force on the base 100 to move the base 100 away from the base 200, or the first elastic member 300 generates a force on the base 200 to move the base 200 away from the base 100, or the first elastic member 300 generates a force on the base 100 and the base 200 to move away from each other. In this case, the base 100 and / or the base 200 need to overcome the elastic force of the first elastic member 300 before they can cover each other.

[0069] In summary, the present application sets a connection structure 110 on the base 100, and sets a matching structure 210 that matches the connection structure 110 on the base 200. When the base 100 and the base 200 are in a covered state, the connection structure 110 and the matching structure 210 are engaged with each other, which, on the one hand, reduces the difficulty of installing the base 100 and the base 200, making the subsequent installation process of the base 100 and the base 200 easier, and because the connection structure 110 and the matching structure 210 are in an engaged state, when the base 100 and the base 200 are separated, the base 100 and the base 200 will not be quickly separated under the elastic force of the first elastic member 300.

[0070] On the other hand, the connection between the connecting structure 110 and the matching structure 210 can also improve the installation tolerance between the base 100 and the base 200. After the connecting structure and the matching structure 210 are connected, the relative position of the base 100 and the base 200 can be fine-tuned to make the installation between the base 100 and the base 200 more accurate.

[0071] There may be various forms for the arrangement of the connection structure 110 and the matching structure 210 to achieve the effect of reducing the difficulty of installation and removal between the base 100 and the base 200 when the connection structure 110 and the matching structure 210 are engaged. Two possible implementations will be exemplarily shown below.

[0072] In the first configuration, the connection structure 110 may be an elastic block, the matching structure 210 may be a slot, and the connection structure 110 and the matching structure 210 may be elastically connected. Alternatively, the connection structure 110 may be a slot, the matching structure 210 may be an elastic block, and the connection structure 110 and the matching structure 210 may be elastically connected.

[0073] The elastic card block is an elastic connecting element used in a mechanical system, and the card slot refers to a groove structure used to install or support the elastic card block. The elastic card block and the card slot are arranged opposite to each other.

[0074] The following only takes the case where the connection structure 110 is an elastic block and the matching structure 210 is a slot as an example. For example, the elastic block can be arranged on the inner wall of the base 100 , and in this case, the slot can be arranged on the outer wall of the base 200 .

[0075] Elastic snap-fitting refers to a snap-fitting method in which either or both of the connecting structure 110 and the matching structure 210 undergo elastic deformation during the snap-fitting process.

[0076] When the first setting form is selected, during the process of covering the base 100 and the base 200, the elastic card block is squeezed and deformed. When the base 100 or the base 200 is moved to make the elastic card block relative to the card slot, the elastic card block resumes its deformation. At this time, the elastic card block is engaged in the card slot. The deformable property of the elastic card block is utilized to achieve elastic engagement between the connecting structure 110 and the matching structure 210. When the connecting structure 110 and the matching structure 210 need to be separated, the connecting structure 110 and the matching structure 210 can be separated by deformation of the elastic card block.

[0077] In the second configuration, the connection structure 110 is a limit groove, the matching structure 210 is a limit block, and the connection structure 110 and the matching structure 210 are interference fit. Alternatively, the connection structure 110 is a limit block, the matching structure 210 is a limit groove, and the connection structure 110 and the matching structure 210 are interference fit.

[0078] The following only takes the case where the connecting structure 110 is a limiting groove and the matching structure 210 is a limiting block as an example.

[0079] For example, the limiting groove may be a slot structure provided on the base 100. The limiting groove may be integrally formed with the base 100 when the base 100 is formed, or the limiting groove may be provided by cutting, engraving or other processes after the base 100 is formed.

[0080] The limiting block may be a strip structure on the base 200. The limiting block may be integrally formed with the base 200 when the base 200 is formed, or the limiting block may be separately formed from the base 200 and then assembled.

[0081] The limiting groove and the limiting block can be arranged relative to each other so that the limiting block can be accurately inserted into the limiting groove. The diameter of the limiting block is slightly larger than the groove diameter of the limiting groove so that the connecting structure 110 and the matching structure 210 can achieve interference fit.

[0082] Interference fitting means that during the fitting process, the connection structure 110 and the matching structure 210 are in an interference fit state.

[0083] When the second arrangement is used, during the process of the base 100 and the base 200 covering each other, the limit block is inserted into the limit groove, so that the connection structure 110 and the matching structure 210 can be connected by interference fit. This arrangement can make the installation of the base 100 and the base 200 easier, and the connection structure 110 and the matching structure 210 can be connected by plugging or pulling.

[0084] The following is an introduction to possible structural forms of the elastic block in conjunction with the accompanying drawings.

[0085] Figure 4A schematic diagram of the structure of the base provided in an embodiment of the present application at a certain viewing angle. Figure 5 for Figure 4 Magnified view of section A. Figure 6 for Figure 4 Magnified view of section B. Figure 7 A schematic diagram of the structure of the base provided in an embodiment of the present application.

[0086] like Figures 4 to 7 As shown, the elastic block includes a connecting portion 111 and a clamping portion 112 connected to each other, and the clamping portion 112 protrudes relative to the connecting portion 111. When the connecting structure 110 is an elastic block, the base 100 is provided with a first mounting groove 140, and the connecting portion 111 is connected to the groove wall of the first mounting groove 140. When the matching structure 210 is an elastic block, the base 200 is provided with a second mounting groove, and the connecting portion 111 is connected to the groove wall of the second mounting groove.

[0087] In the embodiment of the present application, the connecting portion 111 is used to connect the clamping portion 112 so that the clamping portion 112 can be clamped with the matching structure 210. The connecting portion 111 can be integrally formed with the clamping portion 112, or the connecting portion 111 and the clamping portion 112 can be formed separately and then assembled.

[0088] The connecting portion 111 may be a connecting rod, or a second elastic member. When the connecting portion 111 is a connecting rod, the connecting portion 111 should have the property of elastic deformation. The second elastic member may be a spring or a spring sheet, etc. The connecting portion 111 may be one section, located on one side of the clamping portion 112, or may be two sections, located on both sides of the clamping portion 112 respectively.

[0089] like Figure 5 as well as Figure 6 As shown, the connecting portion 111 and the side wall of the base 100 are in the same plane, and the clamping portion 112 protrudes from the side wall of the base 100 .

[0090] The first mounting groove 140 may be a groove structure provided on the base 100. The first mounting groove 140 may be a circular groove or a square groove, etc. The first mounting groove 140 may be a through groove, or a blind groove.

[0091] The second mounting groove may be a groove structure provided on the base 200. The second mounting groove may be a circular groove or a square groove, etc., the second mounting groove may be a through groove, or the second mounting groove may be a blind groove.

[0092] In summary, the elastic card block is formed by the connecting portion 111 and the clamping portion 112, which can increase the diversity of the types of elastic card blocks. The clamping portion 112 is set to protrude from the connecting portion 111, so that the clamping portion 112 can be more effectively clamped with the matching structure 210. The first installation groove 140 is provided on the base 100 or the second installation groove is provided on the base 200, which can not only position the installation position of the elastic card block, but also make the installation of the elastic card block easier.

[0093] Please continue to refer to Figures 4 to 7 As shown, when the connection structure 110 is an elastic block, a first gap 150 may be provided between the connection structure 110 and the first installation slot 140. When the matching structure 210 is an elastic block, a second gap may be provided between the matching structure 210 and the second installation slot.

[0094] The first gap 150 is a reserved space between the elastic block and the first installation slot 140 wall, and the size of the first gap 150 can be selected according to actual manufacturing conditions. The second gap is a reserved space between the elastic block and the second installation slot, and the size of the second gap can also be selected according to actual manufacturing conditions.

[0095] However, it should be noted that when the first mounting groove 140 or the second mounting groove is a through groove, the first gap 150 and the second gap should not be too large to prevent dust and metal particles from invading the interior of the contactor and affecting the internal components of the contactor.

[0096] Through the above-mentioned arrangement, when the connecting structure 110 is an elastic card block, a first gap 150 is reserved between the connecting structure 110 and the first mounting groove 140, or, when the mating structure 210 is an elastic card block, a second gap is reserved between the mating structure 210 and the second mounting groove. When the connecting structure 110 and the mating structure 210 are separated, a tool can be inserted into the first gap 150 or the second gap to assist in separating the connecting structure 110 and the mating structure 210, thereby reducing the difficulty of installation between the base 100 and the base 200.

[0097] Figure 8 A schematic diagram of the structure of the base provided in an embodiment of the present application from another perspective.

[0098] like Figure 3 , Figure 7 as well as Figure 8As shown, the base 100 is provided with a first mounting hole 120, and the base 200 is provided with a second mounting hole 220. When the matching structure 210 is a slot, the slot passes through the base 200 along the first direction OX, and the first direction OX is perpendicular to the mounting direction of the base 100 and the base 200. When the connecting structure 110 is a slot, the slot passes through the base 100 along the first direction OX. The base 100 and / or the base 200 can move along the first direction OX so that the positions of the first mounting hole 120 and the second mounting hole 220 are opposite, and the first mounting hole 120 and the second mounting hole 220 are used for the fastener 400 to pass through.

[0099] The first mounting hole 120 may be a threaded hole, and the second mounting hole 220 may be a through hole.

[0100] The number of the first mounting hole 120 may be one, or the number of the first mounting holes 120 may be multiple. Accordingly, the number of the second mounting holes 220 may be one, or the number of the second mounting holes 220 may be multiple.

[0101] For example, when there are multiple first mounting holes 120 and multiple second mounting holes 220 , the multiple first mounting holes 120 can be respectively disposed on both sides of the base 100 . Similarly, the multiple second mounting holes 220 can also be respectively disposed on both sides of the base 200 .

[0102] The plurality of first mounting holes 120 and the plurality of second mounting holes 220 can be provided so that the base 100 and the pedestal 200 can be fixed more firmly when the fastener 400 is used, thereby increasing the firmness of the base 100 and the pedestal 200 after installation.

[0103] It should be noted that the number of the first mounting holes 120 should be the same as the number of the second mounting holes 220 .

[0104] When the base 100 and the base 200 are covered, and the positions of the first mounting hole 120 and the second mounting hole 220 correspond, the fastener 400 is first passed through the second mounting hole 220 and then through the first mounting hole 120 to fix the relative position of the base 100 and the base 200. When there is a slight deviation between the setting positions of the first mounting hole 120 and the second mounting hole 220, the base 100 and / or the base 200 are moved along the first direction OX to adjust the relative position of the base 100 and the base 200 so that the positions of the first mounting hole 120 and the second mounting hole 220 correspond. The fastener 400 can be a bolt or a strip.

[0105] During the installation of the base 100 and the base 200, the connection structure 110 and the matching structure 210 are firstly engaged, and then the base 100 and the base 200 are fixed by the fastener 400. During the disassembly of the base 100 and the base 200, the fastener 400 is firstly removed, and then the connection structure 110 and the matching structure 210 are separated, and the disassembly of the base 100 and the base 200 is completed.

[0106] Through the above arrangement, the first mounting hole 120 is arranged on the base 100, the second mounting hole 220 is arranged on the base 200, and the fastener 400 passes through the first mounting hole 120 and the second mounting hole 220, so as to fix the base 100 and the base 200. In this way, in addition to the connection between the connection structure 110 and the matching structure 210 to connect the base 100 and the base 200, the fastener 400 fixes the base 100 and the base 200, which can further improve the connection reliability between the base 100 and the base 200, and reduce the possibility of separation between the base 100 and the base 200 when the contactor is bumped or dropped. Compared to the related art in which the base 100 and / or the base 200 overcome the elastic force of the first elastic member 300 while the base 100 and the base 200 are fixed by the fastener 400, the present application reduces the time cost and labor cost required during the installation process of the base 100 and the base 200, and improves the safety of the base 100 and the base 200 during the disassembly process.

[0107] Furthermore, a slot is provided that passes through the base 200 along the first direction OX, or a slot is provided that passes through the base 100 along the first direction OX, so that the tolerance of installation between the base 100 and the base 200 can be increased. After the connecting structure 110 is connected with the slot, if the positions of the first mounting hole 120 and the second mounting hole 220 are not aligned, the position of the base 200 or the base 100 can be adjusted along the slot that passes through the base 200 along the first direction OX, or the slot that passes through the base 100 along the first direction OX, until the first mounting hole 120 and the second mounting hole 220 are aligned, and then fastened using the fastener 400.

[0108] In a possible design, there may be multiple elastic card blocks, and the multiple elastic card blocks may be spaced apart along a first direction OX. The multiple elastic card blocks are all engaged with the card slots, and the first direction OX is perpendicular to the installation direction of the base 100 and the base 200 .

[0109] The number of the elastic blocks may be 4, 7, or 10, etc. The plurality of elastic blocks may be arranged at equal intervals along the first direction OX, or the plurality of elastic blocks may be arranged at non-equal intervals along the first direction OX. For example, the spacing between the elastic blocks close to the first elastic member 300 in the first direction OX may be smaller, and the spacing between the elastic blocks far from the first elastic member 300 in the first direction OX may be larger.

[0110] Through the above configuration, multiple elastic blocks are provided to be connected with the card slots. On the one hand, the elastic force of the first elastic member 300 can be overcome more easily, ensuring that the base 100 and the base 200 will not be easily separated after being covered. On the other hand, when one elastic block is damaged, the remaining elastic blocks can still be effectively connected with the card slots, thereby increasing the service life of the shell assembly and reducing the maintenance cost of the shell assembly in the later stage.

[0111] In a possible design, a side of the connecting structure 110 facing the matching structure 210 may be provided with an arc chamfer, or a side of the matching structure 210 facing the connecting structure 110 may be provided with an arc chamfer.

[0112] Through the above-mentioned setting, an arc chamfer is set on the side of the connecting structure 110 facing the matching structure 210, or an arc chamfer is set on the side of the matching structure 210 facing the connecting structure 110, or an arc chamfer is set on the side opposite to the matching structure 210. This not only makes the clamping and disassembly process between the connecting structure 110 and the matching structure 210 smoother, but the arc chamfer can also guide the matching structure 210, thereby reducing the difficulty of installation between the base 100 and the base 200.
