Description

TECHNICAL FIELD

[0001] The application relates to the technical field of switches, in particular to a breaking structure. BACKGROUND

[0002] The breaking structure is an electrical device capable of controlling current on-off, and comprises a static contact and a shell. The shell is generally made of plastic material to isolate conductors and ground metal parts.

[0003] In the prior art, the shell made of plastic material is prone to deformation. During assembly and connection of the shell and the static contact, interference between the static contact and the shell is caused, which is inconvenient for installation and operation and has low installation efficiency. CONTENT OF THE UTILITY MODEL

[0004] The application provides a breaking structure for improving installation efficiency of the breaking structure.

[0005] In order to achieve the above purpose, the application provides a breaking structure, which comprises a static contact and a shell. The static contact comprises a fixed segment and a connecting segment connected with each other. The shell comprises a first shell and a second shell arranged oppositely. The static contact is arranged on the first shell through a threaded connection structure. One side of the first shell facing the second shell is provided with a first groove, and one end of the first groove penetrates one side of the first shell. The second shell is provided with a second groove, and one end of the second groove penetrates one side of the second shell. The second groove is arranged oppositely to the first groove, and the first groove and the second groove form an installation space. The installation space comprises a first installation space matched with the fixed segment and a second installation space matched with the connecting segment. The fixed segment is arranged in the first installation space, and one end of the connecting segment away from the fixed segment is located outside the second installation space. The first installation space has a first wall surface, and a groove wall of the first groove for forming the first wall surface is provided with a first protruding part protruding towards the first installation space. One side of the first protruding part away from the first wall surface is in supporting contact with the fixed segment.

[0006] When the fixed segment is connected with the first shell through the threaded connection structure, the fixed segment is subjected to the force of the threaded connection structure and the force of the first protruding part, and the forces are balanced as much as possible, thereby improving the stability of the fixed segment on the first shell.

[0007] In a possible implementation manner, the first protruding part is arranged at a position close to the threaded connection structure.

[0008] When the fixed segment is connected with the first shell, the first protruding part in contact with the fixed segment is more in number and has a larger contact area, thereby ensuring the firmness of the fixed segment on the first shell.

[0009] In a possible implementation manner, the first protruding part is arranged at a position close to the threaded connection structure.

[0010] When the fixed segment is connected with the first shell through the threaded connection structure, the fixed segment is subjected to the force of the threaded connection structure and the force of the first protruding part, and the forces are balanced as much as possible, thereby improving the stability of the fixed segment on the first shell.

[0011] In a possible implementation manner, the first protruding part is arranged at a position close to the threaded connection structure.

[0012] When the fixed segment is connected with the first shell through the threaded connection structure, the fixed segment is subjected to the force of the threaded connection structure and the force of the first protruding part, and the forces are balanced as much as possible, thereby improving the stability of the fixed segment on the first shell.

[0013] In a possible implementation, as an optional mode, a side of the first protruding part close to the second shell is provided as a first inclined surface, and the distance between the first inclined surface and the first wall surface gradually decreases in the direction from the first groove to the second groove.

[0014] When the fixed section is placed in the first groove, the first inclined surface plays a guiding role, facilitating the placement of the fixed section in the first groove.

[0015] In a possible implementation, the height of the first protruding part is 0.2mm-0.6mm.

[0016] In a possible implementation, a second protruding part protruding towards the first mounting space is arranged on the groove wall of the second groove for forming the first wall surface. The height of the second protruding part is less than or equal to the height of the first protruding part.

[0017] When the height of the second protruding part is less than the height of the first protruding part, in the process of inserting the part of the fixed section outside the first groove into the second groove, there is a gap between the fixed section and the second protruding part, and no interference phenomenon occurs between the fixed section and the second protruding part, facilitating the matching installation of the first shell and the second shell.

[0018] When the height of the second protruding part is equal to the height of the first protruding part, after the part of the fixed section outside the first groove is inserted into the second groove, the second protruding part can be in supporting contact with the fixed section, and the second protruding part has a supporting force on the fixed section, which can improve the stability of the fixed section arranged on the shell.

[0019] In a possible implementation, a plurality of limiting bosses are further arranged on the groove wall of the first groove for forming the first wall surface, the limiting bosses protrude towards the first mounting space, and the height of the limiting bosses is less than the height of the first protruding part.

[0020] When the fixed section is connected with the first shell through the threaded connection structure, since there is a gap between the fixed section and the first wall surface, there is a possibility that the fixed section rotates around the threaded connection structure. When the fixed section rotates around the threaded connection structure, the arrangement of the limiting bosses can support the fixed section to prevent the fixed section from continuing to rotate, avoid the shaking of the fixed section relative to the first shell, and improve the firmness of the fixed section installed on the first shell.

[0021] In a possible implementation, the first mounting space further has a second wall surface opposite to the first wall surface, and a third wall surface and a fourth wall surface opposite to each other, and the first wall surface, the second wall surface, the third wall surface and the fourth wall surface surround to form the first mounting space. The third wall surface is a groove wall of the first groove; the third wall surface is provided with a third protruding portion protruding towards the first mounting space, and one side of the fixing segment close to the third wall surface is limited to the third protruding portion.

[0022] When the fixing segment is installed in the first housing, one side of the fixing segment close to the third wall surface is limited to the third protruding portion, and the whole side of the fixing segment close to the third wall surface does not contact the third wall surface, so that a gap is formed between the one side of the fixing segment close to the third wall surface and the third wall surface, and a heat dissipation exhaust passage can be formed between the fixing segment and the third wall surface, which is beneficial to dissipate heat inside the disconnecting structure, avoids high temperature in the disconnecting structure, and further prolongs the service life of the disconnecting structure.

[0023] In a possible implementation, the fourth wall surface is provided with a fourth protruding portion protruding towards the first mounting space, and one side of the fixing segment close to the fourth wall surface is limited to the fourth protruding portion.

[0024] When the fixing segment is installed in the first mounting space, one side of the fixing segment close to the fourth wall surface is limited to the fourth protruding portion, and the whole side of the fixing segment close to the fourth wall surface does not contact the fourth wall surface, so that a gap is formed between the one side of the fixing segment close to the fourth wall surface and the fourth wall surface, and a heat dissipation exhaust passage can be formed between the fixing segment and the fourth wall surface, which is beneficial to dissipate heat inside the disconnecting structure, avoids high temperature in the disconnecting structure, and further prolongs the service life of the disconnecting structure.

[0044] The sectional structure provided by the embodiments of the present application can be a circuit breaker or a disconnector.

[0045] Please refer to Figure 2 As shown in the drawings, the sectional structure includes a static contact 1 and a housing, and the housing includes a first housing 2 and a second housing 3 arranged opposite to each other.

[0046] As Figure 1 shown, the static contact 1 includes a fixed section 11 and a connecting section 12 connected to each other.

[0047] In actual cases, the connecting section 12 is used to connect with an external circuit, and the static contact 1 further comprises a contact section 13 used to contact with a moving contact of the breaking structure. When the moving contact contacts with the contact section 13, the circuit in which the breaking structure is located is turned on, and when the moving contact is separated from the contact section 13, the circuit in which the breaking structure is located is turned off.

[0048] One end of the fixed section 11 is connected with one end of the connecting section 12, and the other end of the fixed section 11 is connected with the contact section 13.

[0049] The connecting mode between the fixed section 11, the connecting section 12 and the contact section 13 can be welding or clamping, etc. Of course, the static contact 1 can also be an integrated structure, i.e. the fixed section 11, the connecting section 12 and the contact section 13 are integrally processed and formed.

[0050] The specific structure and processing and forming mode of the static contact 1 are not limited here, and are subject to actual cases.

[0051] In specific implementation, the fixed section 11 and the connecting section 12 can both be plate-shaped structures, and of course, the actual cases are not limited to this.

[0052] It should be noted that the first shell 2 and the second shell 3 are oppositely arranged, and the first shell 2 and the second shell 3 can be shell-shaped structures with open accommodating spaces. The opening of the accommodating space of the first shell 2 is arranged towards the second shell 3, and the opening of the accommodating space of the second shell 3 is arranged towards the first shell 2. After the first shell 2 and the second shell 3 are buckled together, the accommodating space of the breaking structure is formed, and other components included in the breaking structure, such as the moving contact, the arc extinguishing grid, etc. can be arranged in the accommodating space.

[0053] In actual operation, one of the first shell 2 and the second shell 3 can be a base of the breaking structure, and the other can be a cover of the breaking structure. For example, the first shell 2 is the base, and the second shell 3 is the cover. The second shell 3 is arranged on the first shell 2 to form the accommodating space.

[0054] In combination with the figures shown in Figure 3 , Figure 4 and Figure 1 , one side of the first shell 2 towards the second shell 3 is provided with a first groove 21, and one end of the first groove 21 penetrates one side of the first shell 2.

[0055] In specific implementation, the first groove 21 can be opened on the side of the first shell 2 towards the second shell 3, or a wall surface used to surround and form the first groove 21 can be arranged on the side of the first shell 2 towards the second shell 3 to form the first groove 21. The forming mode of the first groove 21 is not limited here.

[0056] One end of the first recess 21 penetrates one face of the first housing 2. Specifically, the first housing 2 has an adjacent first surface and a second surface, and the face of the first housing 2 provided with the first recess 21 is defined as the first surface, and the face connected with the second housing 3 is defined as the second surface. The first recess 21 is provided on the first surface, and one end of the first recess 21 penetrates the second surface, so that a first through hole is formed on the second surface.

[0057] In combination Figures 3 to 5 , Figure 1 As shown in FIG. 1, the second housing 3 is provided with a second recess 31, and the second recess 31 is oppositely provided with the first recess 21.

[0058] Similarly, in a specific implementation, the second recess 31 can be formed on the face of the second housing 3 facing the first housing 2, or a wall surface for surrounding the second recess 31 can be provided on the face of the second housing 3 facing the first housing 2, so as to form the second recess 31. The forming mode of the second recess 31 is not specifically limited here.

[0059] One end of the second recess 31 penetrates one face of the second housing 3, the second recess 31 is oppositely provided with the first recess 21, and the first recess 21 and the second recess 31 surround to form a mounting space. The mounting space includes a first mounting space matched with the fixed section 11 and a second mounting space matched with the connecting section 12, the fixed section 11 is arranged in the first mounting space, and one end of the connecting section 12 away from the fixed section 11 is located outside the second mounting space.

[0060] Specifically, the second housing 3 has an adjacent third surface and a fourth surface, and the face of the second housing 3 provided with the second recess 31 is defined as the third surface, and the face connected with the first housing 2 is defined as the fourth surface. The second recess 31 is provided on the third surface, and one end of the second recess 31 penetrates the fourth surface, so that a second through hole is formed on the fourth surface.

[0061] In actual cases, the third surface and the first surface are oppositely arranged in parallel, and the second surface and the fourth surface are coplanar and connected. The first through hole and the second through hole surround to form a through hole of the housing.

[0062] The first mounting space is matched with the fixed section 11, and the fixed section 11 is located in the first mounting space. The size and structure of the first mounting space are determined according to the size and structure of the fixed section 11.

[0063] For example, when the fixed section 11 is a plate-shaped structure, the first mounting space can be a cuboid structure. When the fixed section 11 is a multi-prism structure, the first mounting space can be a cuboid structure, and of course, the first mounting space can also be a multi-prism structure.

[0064] The second installation space is matched with the connecting section 12, and the end of the connecting section 12 away from the fixing section 11 extends out of the second installation space through the through opening, that is, the end of the connecting section 12 away from the fixing section 11 is located outside the shell. Figure 2 and Figures 2 to 4 shown.

[0065] In actual situations, the first installation space has a first wall surface and a second wall surface arranged opposite to the first wall surface.

[0066] It should be noted that the first wall and the second wall are arranged opposite each other, that is, the first wall and the second wall are parallel to each other. Because the first installation space is formed by the first groove 21 and the second groove 31, a portion of the first wall is located within the first groove 21, and another portion is located within the second groove 31. Similarly, a portion of the second wall is located within the first groove 21, and another portion is located within the second groove 31.

[0067] A first protrusion 22 protruding toward the first installation space is provided on the groove wall of the first groove 21 for forming the first wall surface, and a surface of the first protrusion 22 away from the first wall surface is in supporting contact with the fixing section 11 .

[0068] When the static contact 1 is mounted on the first housing 2 via the threaded connection structure, the fixed section 11 is in supporting contact with the first protrusion 22. When the fixed section 11 is mounted on the first housing 2, it is supported on the first protrusion 22. The threaded connection structure passes through the first wall surface and is threadedly connected to the fixed section 11.

[0069] In the embodiment provided in the present application, the fixing section 11 is provided on the first housing 2 via a threaded connection structure. Of course, in actual operation, the fixing section 11 can also be riveted to the first housing 2.

[0070] For example, when the fixing section 11 is provided on the first housing 2 via a threaded connection structure, the threaded connection structure may be a screw or a bolt.

[0071] When the threaded connection structure is a screw, threaded holes can be opened at corresponding positions of the first shell 2 and the fixed section 11. After the screw passes through the threaded holes at corresponding positions on the first shell 2 and the fixed section 11, it is threadedly connected to the first shell 2 and the fixed section 11. The screw is tightened to ensure that the fixed section 11 and the first shell 2 are firmly connected, so that the static contact 1 is firmly installed on the first shell 2.

[0072] When the threaded connection structure is a bolt, a threaded hole or through-hole can be provided in the first housing 2, and a matching threaded hole can be provided in the fixing section 11 at a position corresponding to the threaded hole or through-hole in the first housing 2. The end of the bolt's shank, away from the nut, passes through the first housing 2 and is then threadedly connected to the fixing section 11. The bolt is then tightened, thereby securing the static contact 1 to the first housing 2.

[0073] In an example, referring to Figure 5 As shown, an extension 25 is arranged on the first shell 2, the extension 25 extends from the first surface of the first shell 2 to the direction of the second shell 3. The extension 25 is located on the side of the first shell 2 close to the second shell 3, the extension 25 has a surface coplanar with the first wall surface, and the first protrusion 22 is arranged on the extension 25.

[0074] In this case, a threaded hole or a through hole for cooperating with the threaded connection structure can be formed on the extension 25.

[0075] Referring to Figure 6 and Figure 3 As shown, a recess 33 cooperating with the extension 25 is arranged on the second shell 3.

[0076] At this time, in the process of connecting the first shell 2 and the second shell 3, the extension 25 can be first aligned and matched with the recess 33, so that the positioning of the first shell 2 and the second shell 3 is facilitated. After the first shell 2 and the second shell 3 are connected, the extension 25 cooperates with the recess 33, and the extension 25 is located in the recess 33.

[0077] By using the disconnecting structure provided in the embodiments of the present application, in the process of connecting the stationary contact 1 and the shell, the fixed section 11 can be first placed in the first groove 21 according to the preset position and direction, and the fixed section 11 is supported on the first protrusion 22. The threaded connection structure is threadedly connected with the fixed section 11 after penetrating through the first wall surface, thereby connecting the fixed section 11 and the first shell 2, and making the stationary contact 1 fastened on the first shell 2.

[0078] It can be understood that, in the process of rotating the threaded connection structure and tightening the threaded connection structure to fasten the fixed section 11 and the first shell 2, the fixed section 11 is subjected to the force of approaching the first wall surface under the action of the threaded connection structure. Compared with before the threaded connection structure is tightened, after the threaded connection structure is tightened, the distance between the fixed section 11 and the first wall surface is reduced, and correspondingly, the distance between the fixed section 11 and the second wall surface is increased.

[0079] After the fixed section 11 and the first shell 2 are connected, the part of the fixed section 11 located outside the first groove 21 is aligned and matched with the second groove 31 of the second shell 3, and the part of the fixed section 11 located outside the first groove 21 is inserted into the second groove 31, and then the first shell 2 and the second shell 3 are connected.

[0080] In the prior art, after the fixed section 11 is fastened to the first shell 2 through the threaded connection structure, the distance between the fixed section 11 and the first wall surface is reduced, and in the process of inserting the part of the fixed section 11 outside the first groove 21 into the second groove 31, the fixed section 11 is misaligned with the groove wall of the second groove 31 forming the first wall surface, which may cause interference in the assembly process, generate a large friction force, and is not convenient for the installation and connection of the first shell 2 and the second shell 3, which not only reduces the installation efficiency, but also has the possibility of damaging the second shell 3 or the fixed section 11.

[0081] In the present application, even if the distance between the fixed section 11 and the first wall surface is reduced after the fixed section 11 is fastened to the first shell 2 through the threaded connection structure, there is still a gap between the fixed section 11 and the first wall surface due to the arrangement of the first protruding part 22. In the process of inserting the part of the fixed section 11 outside the first groove 21 into the second groove 31, there is a gap between the fixed section 11 and the groove wall of the second groove 31 for forming the first wall surface, and the fixed section 11 and the groove wall of the second groove 31 will not interfere with each other, which is conducive to the matching installation of the first shell 2 and the second shell 3, and can improve the installation efficiency of the first shell 2 and the second shell 3 compared with the prior art.

[0082] Furthermore, after the fixed section 11 is installed on the first shell 2, the fixed section 11 is in contact with the first protruding part 22, and the fixed section 11 will not be in contact with the first wall surface, and will not be in close contact with the first wall surface.

[0083] The arrangement of the first protruding part 22 allows a gap between the side of the fixed section 11 close to the first wall surface and the first wall surface, and the entire side of the fixed section 11 close to the first wall surface will not be in contact with the first wall surface. The fixed section 11 and the first wall surface can form a heat dissipation exhaust passage, which is conducive to the dissipation of heat inside the disconnecting structure, avoids high temperature inside the disconnecting structure, and further prolongs the service life of the disconnecting structure.

[0084] It should be noted that the threaded connection structure can pass through the first protruding part 22, and of course, the threaded connection structure can also be misaligned with the first protruding part 22, which is not limited here.

[0085] As a possible implementation, the first protruding part 22 is arranged on both sides of the threaded connection structure in the length direction of the fixed section 11.

[0086] It should be noted that in the embodiments provided in the present application, the length direction of the fixed section 11 refers to the direction from the end of the fixed section 11 connected to the contact section 13 to the end of the fixed section 11 connected to the connecting section 12.

[0087] The first protruding part 22 is arranged on both sides of the threaded connection structure in the length direction of the fixed section 11.

[0088] In this way, on the one hand, after the fixed section 11 is connected with the first shell 2, the number of the first protruding part 22 in supporting contact with the fixed section 11 is large, the supporting contact area of the fixed section 11 is large, and the firmness of the fixed section 11 arranged on the first shell 2 can be ensured. On the other hand, after the first shell 2 is connected with the fixed section 11 through the threaded connection structure, the two ends of the fixed section 11 in the length direction are prevented from being inclined compared with the first wall surface under the action of the threaded connection structure, and the installation precision of the fixed contact 1 cannot be ensured.

[0089] As an optional mode, the first protruding part 22 is arranged at a position close to the threaded connection structure.

[0090] It should be noted that in the process of rotating the threaded connection structure and tightening the threaded connection structure to tightly connect the fixed section 11 with the first shell 2, the fixed section 11 is subjected to the force of approaching the first wall surface under the action of the threaded connection structure. And the fixed section 11 is subjected to the force of moving away from the first wall surface under the action of the first protruding part 22.

[0091] At this time, the first protruding part 22 is arranged at a position close to the threaded connection structure, which can ensure that the force of the threaded connection structure and the force of the first protruding part 22 acting on the fixed section 11 are balanced as much as possible, and the stability of the fixed section 11 arranged on the first shell 2 is improved.

[0092] The number of the first protruding part 22 is multiple, the supporting contact area of the fixed section 11 is large, and the firmness of the fixed section 11 arranged on the first shell 2 can be ensured. The specific number of the first protruding part 22 is not limited here.

[0093] The structure of the first protruding part 22 can be a long strip structure, an arc structure, or a triangular structure, etc., which is not limited here.

[0094] In actual cases, the first protruding part 22 in the form of a ring can be arranged in the circumferential direction of the threaded connection structure to ensure the stability of the fixed section 11 arranged on the first shell 2.

[0095] In some embodiments, in the direction from the first groove 21 to the second groove 31, a plurality of first protruding parts 22 are arranged on the groove wall of the first groove 21 for forming the first wall surface, and the plurality of first protruding parts 22 are arranged at intervals.

[0096] In this way, not only the supporting contact area of the fixed segment 11 is increased, and the stability of the fixed segment 11 arranged on the first shell 2 is improved, but also the gap between the two adjacent first protrusions 22 can form a heat dissipation exhaust channel, which is beneficial to the heat dissipation of the breaking structure, avoids the temperature of the breaking structure being too high, and further prolongs the service life of the breaking structure.

[0097] In specific implementation, in the length direction of the fixed segment 11, a plurality of rows of first protrusions 22 can be arranged on the groove wall of the first groove 21 for forming the first wall surface, and each row has a plurality of first protrusions 22 arranged at intervals. In this way, the stability of the fixed segment 11 arranged on the first shell 2 is improved, and the channel for air flow and heat is reserved, which is beneficial to heat dissipation, avoids the temperature of the breaking structure being too high, and shortens the service life of the breaking structure.

[0098] As an optional mode, as shown in Figure 5 the side of the first protrusion 22 close to the second shell 3 is arranged as a first inclined surface 221, and the distance between the first inclined surface 221 and the first wall surface gradually decreases in the direction from the first groove 21 to the second groove 31.

[0099] In this way, the first inclined surface 221 plays a guiding role in the process of placing the fixed segment 11 in the first groove 21, which is beneficial to placing the fixed segment 11 in the first groove 21.

[0100] In specific implementation, when a plurality of first protrusions 22 are arranged on the groove wall of the first groove 21 for forming the first wall surface in the direction from the first groove 21 to the second groove 31, only the first protrusion 22 located at the slot position of the first groove 21 can be arranged as having the first inclined surface 221, and the first inclined surface 221 can not be arranged on the remaining first protrusions 22, so as to simplify the design and processing of the first shell 2.

[0101] As an example, the height of the first protrusion 22 is 0.2mm-0.6mm.

[0102] First of all, it should be pointed out that the height of the first protrusion 22 refers to the vertical distance between the side of the first protrusion 22 away from the first wall surface and the first wall surface.

[0103] For example, the height of the first protrusion 22 can be 0.2mm, 0.3mm, 0.45mm, 0.5mm, 0.6mm, etc.

[0104] In specific implementation, the height of the first protrusion 22 can be equal to the distance between the fixed segment 11 and the first wall surface after the fixed segment 11 is installed on the first shell 2, which is not limited here and is subject to actual conditions.

[0105] In another example, referring to Figure 5 As shown in FIG. 2, the groove wall of the second groove 31 for forming the first wall surface is provided with a second protruding portion 32 protruding towards the second mounting space, and the height of the second protruding portion 32 is less than or equal to the height of the first protruding portion 22.

[0106] The height of the second protruding portion 32 refers to the vertical distance between the side of the second protruding portion 32 away from the first wall surface and the first wall surface.

[0107] When the height of the second protruding portion 32 is less than the height of the first protruding portion 22, during the process of inserting the part of the fixing section 11 outside the first groove 21 into the second groove 31, there is a gap between the fixing section 11 and the second protruding portion 32, and no interference phenomenon occurs between the fixing section 11 and the second protruding portion 32, which is beneficial for the matching installation of the first shell 2 and the second shell 3.

[0108] When the height of the second protruding portion 32 is equal to the height of the first protruding portion 22, after the part of the fixing section 11 outside the first groove 21 is inserted into the second groove 31, the second protruding portion 32 can be in supporting contact with the fixing section 11, and the second protruding portion 32 has a supporting force on the fixing section 11, which can improve the stability of the fixing section 11 arranged on the shell.

[0109] Referring to Figure 3 As shown in FIG. 2, the side of the second protruding portion 32 close to the first shell 2 is provided as a second inclined surface 321, and the distance between the second inclined surface 321 and the first wall surface gradually decreases in the direction from the second groove 31 to the first groove 21.

[0110] In this way, during the process of inserting the part of the fixing section 11 outside the first groove 21 into the second groove 31, the second inclined surface 321 plays a guiding role, which facilitates the placement of the fixing section 11 in the second groove 31.

[0111] In a possible implementation, as shown in Figure 5 As shown in FIG. 2, the groove wall of the first groove 21 for forming the first wall surface is further provided with a plurality of limiting bosses 23, the limiting bosses 23 protrude towards the first mounting space, and the height of the limiting bosses 23 is less than the height of the first protruding portion 22.

[0112] The height of the limiting boss 23 refers to the vertical distance between the side of the limiting boss 23 away from the first wall surface and the first wall surface.

[0113] In the process of connecting the fixed segment 11 with the first shell 2 through the threaded connection structure, since there is a gap between the fixed segment 11 and the first wall surface, there is a possibility that the fixed segment 11 rotates around the threaded connection structure. When the phenomenon that the fixed segment 11 rotates around the threaded connection structure occurs, the setting of the limiting boss 23 can support the fixed segment 11 to prevent the fixed segment 11 from continuing to rotate and avoid the fixed segment 11 from shaking relative to the first shell 2, thereby improving the firmness of the fixed segment 11 installed on the first shell 2.

[0114] The specific height and number of the limiting boss 23 are not specifically limited here and are subject to actual conditions.

[0115] In specific implementation, referring to FIG. 1, Figure 1 It can be seen that the groove wall of the first groove 21 for forming the first wall surface is also provided with a plurality of limiting bosses 23 to improve the stability of the fixed segment 11.

[0116] Further, the two sides of the first protruding part 22 along the length direction of the fixed segment 11 are each provided with at least one limiting boss 23.

[0117] In this way, the phenomenon that the two ends of the fixed segment 11 in the length direction rotate towards the first wall surface can be avoided, and the firmness of the fixed segment 11 installed on the first shell 2 is improved.

[0118] As a feasible manner, the first installation space further has oppositely arranged third and fourth wall surfaces, and the first, second, third and fourth wall surfaces surround to form the first installation space.

[0119] In actual conditions, the fixed segment 11 is a plate structure, and the structure of the first installation space is a cuboid structure, and the first, second, third and fourth wall surfaces are all parallel to the length direction of the fixed segment 11.

[0120] The third wall surface is the groove wall of the first groove 21, and in combination with Figure 3 and Figure 6 It can be seen that the third wall surface is provided with a third protruding part 24 protruding towards the first installation space, and one side of the fixed segment 11 close to the third wall surface is limited by the third protruding part 24.

[0121] In this case, after the fixed segment 11 is installed on the first shell 2, one side of the fixed segment 11 close to the third wall surface is limited by the third protruding part 24, and the condition that the entire surface of the fixed segment 11 close to the third wall surface contacts the third wall surface does not occur, so that there is a gap between the one side of the fixed segment 11 close to the third wall surface and the third wall surface, and a heat dissipation exhaust passage can be formed between the fixed segment 11 and the third wall surface, which is beneficial to the heat inside the split structure to be dissipated, avoids the temperature inside the split structure to be too high, and further beneficial to prolong the service life of the split structure.

[0122] Specifically, the number of the third protruding portions 24 can be multiple, and the multiple third protruding portions 24 are arranged along the length direction of the fixed segment 11 in sequence.

[0123] Likewise, referring to Figure 4 , it is shown that the fourth wall surface is provided with a fourth protruding portion 34 protruding towards the first mounting space, and the side of the fixed segment 11 close to the fourth wall surface is limited by the fourth protruding portion 34.

[0124] In this case, after the fixed segment 11 is installed in the first mounting space, the side of the fixed segment 11 close to the fourth wall surface is limited by the fourth protruding portion 34, and the whole side of the fixed segment 11 close to the fourth wall surface does not contact the fourth wall surface, so that there is a gap between the side of the fixed segment 11 close to the fourth wall surface and the fourth wall surface, and a heat dissipation exhaust passage can be formed between the fixed segment 11 and the fourth wall surface, which is beneficial for the heat inside the disconnecting structure to be dissipated, avoids the temperature inside the disconnecting structure being too high, and further, is beneficial for prolonging the service life of the disconnecting structure.

[0125] Specifically, the number of the fourth protruding portions 34 can be multiple, and the multiple fourth protruding portions 34 are arranged along the length direction of the fixed segment 11 in sequence.

[0126] In actual cases, referring to Figure 6 and ​ , it is shown that the second wall surface is also provided with multiple fifth protruding portions 26 protruding towards the first mounting space, and after the fixed segment 11 is installed in the first mounting space, the whole side of the fixed segment 11 close to the second wall surface does not contact the second wall surface, so that there is a gap between the side of the fixed segment 11 close to the second wall surface and the second wall surface, and a heat dissipation exhaust passage can be formed between the fixed segment 11 and the second wall surface, which is beneficial for the heat inside the disconnecting structure to be dissipated, avoids the temperature inside the disconnecting structure being too high, and further, is beneficial for prolonging the service life of the disconnecting structure.
