[0001] The present application relates to the technical field of switch, in particular to a breaking structure. BACKGROUND
[0002] The breaking structure is an electrical device capable of controlling the on-off of current, which generally comprises a shell, a static contact and a dynamic contact. When the static contact and the dynamic contact are in contact, the circuit current of the breaking structure is conducted, and the circuit works normally.

If the heat inside the breaking structure is not discharged in time, the temperature of the breaking structure will be too high. The high temperature will not only cause the misoperation of the breaking structure, but also bring electrical safety hazards to the use of the product, such as causing the premature aging of the insulation part, the accelerated oxidation of the contact point and other adverse conditions.
[0004] In the prior art, a heat dissipation device is generally arranged on the shell to discharge the heat inside the breaking structure. However, this way not only increases the cost of the breaking structure, but also increases the occupied space of the breaking structure. CONTENT OF THE INVENTION
[0005] The present application provides a breaking structure for effectively realizing the heat dissipation function of the breaking structure without increasing the cost and the occupied space of the breaking structure.
[0006] In order to achieve the above purpose, the present application provides a breaking structure comprising a static contact and a shell, the static contact comprising a fixed segment and a connecting segment connected with each other.

[0008] Compared with the prior art, the breaking structure provided by the embodiment of the application uses the mounting space reserved on the shell for mounting the static contact, sets the first protruding part in the mounting space to form a heat dissipation exhaust channel between the shell and the static contact, which not only facilitates heat dissipation of the shell through the heat dissipation exhaust channel, thereby avoiding excessive temperature rise in the shell and ensuring that the working temperature of the breaking structure is within a normal range, but also does not occupy space outside the shell of the breaking structure. The application reasonably utilizes the space in the shell, does not cause waste of space, does not increase the occupied space of the breaking structure, and does not set a heat dissipation device on the shell, thereby saving the cost of the breaking structure.

[0012] When the static contact is mounted on the shell, the fixed section is located in the mounting space, and one side of the fixed section close to the second wall surface is limited by the second protruding part. The second protruding part is arranged to form a gap between one side of the fixed section close to the second wall surface and the second wall surface, thereby avoiding the case that one side of the fixed section close to the second wall surface is in contact with the second wall surface.

The second protruding parts can be arranged in an array on the second wall surface, a linear heat dissipation exhaust passage can be formed between two adjacent columns or rows of the second protruding parts, heat can be guided, and the flow of heat is facilitated.
[0015] In a possible implementation, the mounting space further has a third wall surface and a fourth wall surface arranged oppositely, and the first wall surface, the second wall surface, the third wall surface, and the fourth wall surface surround the mounting space to form a cuboid structure. The third wall surface is provided with a third protruding part protruding toward the mounting space, and one side of the fixed section close to the third wall surface is limited by the third protruding part.
[0016] When the above technical solution is adopted, after the static contact is installed on the shell, the fixed section is located in the mounting space, and one side of the fixed section close to the third wall surface is limited by the third protruding part. The third protruding part is arranged, so that there is a gap between the one side of the fixed section close to the third wall surface and the third wall surface, and the one side of the fixed section close to the third wall surface does not contact the third wall surface.

[0017] In a possible implementation, the number of the third protruding parts is multiple, and the third protruding parts are arranged in an array on the third wall surface.
[0018] When the above technical solution is adopted, after the static contact is installed on the shell, the number of the third protruding parts in contact with the fixed section is large, the limiting area of the fixed section is large, and the firmness of the fixed section arranged on the shell can be ensured.

[0020] When the fixed contact is installed on the shell, the fixed section is located in the installation space, and the side of the fixed section close to the fourth wall is limited by the fourth protruding part. The fourth protruding part is arranged to make the side of the fixed section close to the fourth wall have a gap with the fourth wall, so that the whole side of the fixed section close to the fourth wall does not contact the fourth wall.

[0021] In a possible implementation, the number of fourth protruding parts is multiple, and the multiple fourth protruding parts are arranged in an array on the fourth wall.
[0022] When the fixed contact is installed on the shell, the number of fourth protruding parts in contact with the fixed section is more, and the limiting area of the fixed section is larger, so that the firmness of the fixed section arranged on the shell can be ensured.

The first groove and the second groove form an installation space and an installation hole. On the length direction of the fixed section, the two sides of the threaded connection structure are provided with first protruding parts.
[0026] When the technical solution is adopted, on one hand, after the fixed section is connected with the shell, the number of the first protruding parts in contact with the fixed section is large, the contact area of the support of the fixed section is large, and the firmness of the fixed section arranged on the shell can be ensured. On the other hand, the phenomenon that the two ends of the fixed section are inclined compared with the first wall surface under the action of the threaded connection structure is avoided, and the installation precision of the static contact cannot be ensured.
[0027] In a possible implementation, the shell is further provided with a heat dissipation hole, and a dust screen is arranged at the heat dissipation hole.

For example, the "connection" or "connection" of the mechanical structure can mean a physical connection, such as a fixed connection, for example, a fixed connection by a spacer, such as a fixed connection by a screw, bolt or other spacer; the physical connection can also be a detachable connection, such as a mutual clamping or clamping connection; the physical connection can also be integrally connected, such as welding, bonding or integrally formed connection. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0047] The present application provides a breaking structure, and it should be noted that the breaking structure provided by the embodiments of the present application can be a circuit breaker or a disconnector.
[0048] Please refer to Figures 1 to 3 As shown in the figure, the breaking structure includes a static contact 1 and a housing 2, the static contact 1 is arranged in the housing 2, and the static contact 1 includes a fixed segment 11 and a connecting segment 12 connected to each other.
[0049] In actual cases, the connecting segment 12 is used to connect with an external circuit, and the static contact 1 further includes a contact segment 13 used to contact with a moving contact of the breaking structure. When the moving contact contacts with the contact segment 13, the circuit in which the breaking structure is located is conducted, and when the moving contact is separated from the contact segment 13, the circuit in which the breaking structure is located is disconnected.
[0050] One end of the fixed segment 11 is connected with one end of the connecting segment 12, and the other end of the fixed segment 11 is connected with the contact segment 13.
[0051] The connection mode between the fixed segment 11, the connecting segment 12 and the contact segment 13 can be welding or clamping, etc. Of course, the static contact 1 can also be an integral structure, that is, the fixed segment 11, the connecting segment 12 and the contact segment 13 are integrally machined and formed.
[0052] The specific structure and machining mode of the static contact 1 are not limited here, and the actual situation is used as the criterion.
[0053] In specific implementation, the structure of the fixed segment 11 and the connecting segment 12 can both be plate-shaped structures, and of course, the actual situation is not limited to this.
[0054] The shell 2 is provided with a mounting hole matched with the connecting section 12, and the shell 2 is provided with a mounting space communicated with the mounting hole and matched with the fixing section 11. The fixing section 11 is located in the mounting space, and the end of the connecting section 12 away from the fixing section 11 extends out of the shell 2 through the mounting hole.
[0055] The end of the connecting section 12 away from the fixing section 11 extends out of the shell 2 through the mounting hole, that is, a part of the connecting section 12 is located in the mounting hole, and the end of the connecting section 12 away from the fixing section 11 is located outside the shell 2, as shown in Figure 1 and Figure 2 .
[0056] In specific implementation, the structure and size of the mounting hole can be matched with the connecting section 12, and the structure and size of the mounting hole are determined according to the shape and size of the connecting section 12, as long as the mounting hole can allow the connecting section 12 to pass through. At the same time, the connecting section 12 and the hole wall of the mounting hole have a mounting gap.
[0057] It should be noted that the mounting gap refers to a gap between the connecting section 12 and the hole wall of the mounting hole, so that the mounting space is communicated with the outside through the mounting gap.
[0058] The size and structure of the mounting space are determined according to the size and structure of the fixing section 11.
[0059] Exemplarily, when the fixing section 11 is a plate structure, the mounting space can be a cuboid structure. When the fixing section 11 is a multi-prism structure, the mounting space can be a cuboid structure, and of course, the mounting space can also be a multi-prism structure.
[0060] The mounting space has a first wall surface, and the first wall surface is provided with a first protruding part 21 protruding towards the mounting space, and one side of the first protruding part 21 away from the first wall surface is in supporting contact with the fixing section 11.
[0061] The structure of the first protruding part 21 can be a long strip structure, an arc structure, or a triangular structure, etc., which is not limited here.
[0062] When the fixed contact 1 is arranged on the shell 2, the fixing section 11 is in supporting contact with the first protruding part 21. In fact, the fixing section 11 is fixedly connected with the shell 2, so as to fixedly arrange the fixed contact 1 on the shell 2.
[0063] The fixed connection mode of the fixed contact 1 and the shell 2 is not limited here, and exemplarily can be riveting, bonding, clamping, etc.
[0064] When the fixing section 11 is arranged on the shell 2, the fixing section 11 is supported on the first protruding part 21, and the fixing section 11 does not contact the first wall surface, and does not abut against the first wall surface.
[0065] The first protruding part 21 is arranged such that a gap is formed between the surface of the fixing segment 11 close to the first wall surface and the first wall surface, and the entire surface of the fixing segment 11 close to the first wall surface does not contact the first wall surface. The fixing segment 11 and the first wall surface can form a heat dissipation exhaust channel. It should be understood that, since the mounting space is in communication with the mounting hole, a mounting gap is formed between the hole wall of the mounting hole and the connecting segment 12, and thus the heat dissipation exhaust channel formed between the first wall surface and the fixing segment 11 is in communication with the mounting gap. At this time, the heat inside the disconnecting structure can be dissipated through the heat dissipation exhaust channel and the mounting gap, so as to avoid excessively high temperature inside the disconnecting structure, and further, to prolong the service life of the disconnecting structure.
[0066] Compared with the prior art in which a heat dissipation device is arranged on the shell 2 to dissipate the heat inside the disconnecting structure, the disconnecting structure provided in the embodiment of the application utilizes the mounting space reserved on the shell 2 for mounting the stationary contact 1, and a first protruding part 21 is arranged in the mounting space to form a heat dissipation exhaust channel between the shell 2 and the stationary contact 1. This not only facilitates the heat inside the shell 2 to be dissipated through the heat dissipation exhaust channel, so as to avoid excessively high temperature rise inside the shell 2 and ensure that the working temperature of the disconnecting structure is within a normal range, but also does not occupy space outside the shell 2 of the disconnecting structure. The application reasonably utilizes the space inside the shell 2, does not waste space, does not increase the occupied space of the disconnecting structure, and does not arrange a heat dissipation device on the shell 2, thereby saving the cost of the disconnecting structure.
[0067] In actual cases, as shown in Figure 1 , the shell 2 provided in the embodiment of the application includes a first shell 26 and a second shell 27 arranged opposite to each other, and the stationary contact 1 is arranged on the first shell 26 through a threaded connection structure.
[0068] As shown in Figure 1 , Figure 3 and Figure 4 , a first recess 261 is arranged on the surface of the first shell 26 facing the second shell 27, and one end of the first recess 261 penetrates the surface of the first shell 26.
[0069] In specific implementation, the first recess 261 can be formed on the surface of the first shell 26 facing the second shell 27, or a wall surface for surrounding the first recess 261 can be arranged on the surface of the first shell 26 facing the second shell 27 to form the first recess 261. The forming mode of the first recess 261 is not specifically limited here.
[0070] One end of the first recess 261 penetrates one side of the first housing 26. Specifically, the first housing 26 has an adjacent first surface and a second surface, and the side of the first housing 26 provided with the first recess 261 is defined as the first surface, and the side connected with the second housing 27 is defined as the second surface. The first recess 261 is provided on the first surface, and one end of the first recess 261 penetrates the second surface, so that a first mounting hole is formed on the second surface.
[0071] In combination with the figures shown in Figure 1 , Figure 3 and Figure 5 , the second housing 27 is provided with a second recess 271, the second recess 271 penetrates one side of the second housing 27, and the second recess 271 is arranged opposite to the first recess 261, and the first recess 261 and the second recess 271 form a mounting space and a mounting hole.
[0072] Similarly, in specific implementation, the second recess 271 can be formed on the side of the second housing 27 facing the first housing 26, or a wall surface for forming the second recess 271 can be arranged on the side of the second housing 27 facing the first housing 26, so as to form the second recess 271. The forming mode of the second recess 271 is not specifically limited here.
[0073] The second recess 271 is arranged opposite to the first recess 261, and the first recess 261 and the second recess 271 form a mounting space.
[0074] Specifically, the second housing 27 has an adjacent third surface and a fourth surface, and the side of the second housing 27 provided with the second recess 271 is defined as the third surface, and the side connected with the first housing 26 is defined as the fourth surface. The second recess 271 is provided on the third surface, and one end of the second recess 271 penetrates the fourth surface, so that a second mounting hole is formed on the fourth surface.
[0075] In actual cases, the third surface and the first surface are arranged in parallel, and the second surface and the fourth surface are coplanar and connected. The first mounting hole and the second mounting hole form a mounting hole of the housing 2.
[0076] Since the mounting space is formed by the first recess 261 and the second recess 271, part of the first wall surface is located in the first recess 261, and the other part is located in the second recess 271.
[0077] The fixing section 11 is attached to the first housing 26 via a threaded connection structure, which may be a screw or a bolt. When the threaded connection structure is a screw, threaded holes may be provided at corresponding locations on the first housing 26 and the fixing section 11. The screw, after passing through the threaded holes at corresponding locations on the first housing 26 and the fixing section 11, is threadedly connected to the first housing 26 and the fixing section 11. The screw is then tightened, thereby securing the fixing section 11 to the first housing 26 and securing the static contact 1 to the first housing 26.
[0078] When the threaded connection structure is a bolt, a threaded hole or through-hole can be provided in the first housing 26, 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 26. The end of the bolt's shank, distal from the nut, passes through the first housing 26 and is then threadedly connected to the fixing section 11. The bolt is then tightened, thereby firmly connecting the fixing section 11 and the first housing 26, and securely mounting the static contact 1 on the first housing 26.
[0079] In practice, when the fixing section 11 is attached to the first housing 26 via the threaded connection structure, the fixing section 11 is in supporting contact with the first protrusion 21. When the fixing section 11 is installed on the first housing 26, the fixing section 11 is supported on the first protrusion 21. The threaded connection structure passes through the first wall surface and is threadedly connected to the fixing section 11.
[0080] In one example, see Figures 2 to 4 As shown, an extension portion 262 is provided on the first housing 26, and the extension portion 262 extends from the first surface of the first housing 26 toward the second housing 27. The extension portion 262 is located on a side of the first housing 26 close to the second housing 27, and has a surface coplanar with the first wall surface. The extension portion 262 is provided with a first protrusion 21.
[0081] In this case, a threaded hole or a through hole for cooperating with the threaded connection structure may be opened on the extension portion 262 .
[0082] refer to Figure 5 and Figure 6 As shown, a recessed portion 272 is provided on the second housing 27 to mate with the extension 262. During the connection of the first and second housings 26, 27, the extension 262 can be aligned with the recessed portion 272 to facilitate positioning of the first and second housings 26, 27. After the first and second housings 26, 27 are connected, the extension 262 mates with the recessed portion 272 and is located within the recessed portion 272.
[0083] Thus, when connecting the static contact 1 to the housing 2, first, the fixing section 11 can be placed in the first groove 261 according to the preset position and direction, and the fixing section 11 is supported on the first protrusion 21. The fixing section 11 and the first housing 26 are connected using a threaded connection structure, so that the static contact 1 is fastened to the first housing 26.
[0084] It is understood that during the process of rotating and tightening the threaded connection structure to securely connect the fixed segment 11 to the first housing 26, the fixed segment 11 is subjected to a force toward the first wall surface under the action of the threaded connection structure. Compared to before tightening the threaded connection structure, the distance between the fixed segment 11 and the first wall surface decreases after tightening the threaded connection structure.
[0085] After the fixing section 11 and the first shell 26 are connected, the portion of the fixing section 11 outside the first groove 261 is aligned and matched with the second groove 271 of the second shell 27, and the portion of the fixing section 11 outside the first groove 261 is inserted into the second groove 271, and then the first shell 26 and the second shell 27 are connected.
[0086] Even after the fixing section 11 is fastened to the first housing 26 via the threaded connection structure, and the distance between the fixing section 11 and the first wall surface is reduced, a gap still exists between the fixing section 11 and the first wall surface due to the provision of the first protrusion 21. During the process of inserting the portion of the fixing section 11 located outside the first groove 261 into the second groove 271, a gap exists between the fixing section 11 and the groove wall of the second groove 271 that forms the first wall surface. This prevents interference between the fixing section 11 and the second groove 271, facilitating the mating installation of the first and second housings 26, 27 and improving the installation efficiency of the first and second housings 26, 27.
[0087] From the above, it can be seen that by reserving a heat dissipation exhaust channel in the installation space, there is no need to change the appearance of the shell 2 and the main structure of the partition structure. This is not only conducive to the discharge of hot air in the shell 2 and a higher utilization rate of the space, but also helps the smooth assembly of the partition structure and improves the installation efficiency.
[0088] In one possible implementation, see Figure 3 and Figure 5 As shown, there are multiple first protrusions 21. In this way, after the static contact 1 is installed on the housing 2, there are more first protrusions 21 that support and contact the fixed segment 11, and the supporting contact area for the fixed segment 11 is larger, which can ensure that the fixed segment 11 is firmly set on the housing 2.
[0089] The number of the first protrusions 21 is not specifically limited here. The first protrusions 21 are arranged in an array on the first wall surface, and in this case, it is convenient to form linear heat dissipation exhaust channels between two adjacent columns or rows of the first protrusions 21, so as to guide the heat and facilitate the flow of the heat.
[0090] As an optional mode, the mounting space further has a second wall surface arranged opposite to the first wall surface.
[0091] It should be noted that the first wall surface and the second wall surface are arranged opposite to each other, i.e., the first wall surface and the second wall surface are parallel to each other.
[0092] The second wall surface is provided with a second protrusion 22 protruding towards the mounting space, and the side of the fixed section 11 close to the second wall surface is limited by the second protrusion 22.
[0093] Referring to Figure 4 , the groove wall of the first groove 261 for forming the second wall surface is provided with the second protrusion 22. Referring to Figure 6 , the groove wall of the second groove 271 for forming the second wall surface is also provided with the second protrusion 22.
[0094] In specific implementation, after the stationary contact 1 is installed on the housing 2, the fixed section 11 is located in the mounting space, and the side of the fixed section 11 close to the second wall surface is limited by the second protrusion 22. The second protrusion 22 is arranged such that the side of the fixed section 11 close to the second wall surface has a gap with the second wall surface, so as to avoid the case that the entire side of the fixed section 11 close to the second wall surface is in contact with the second wall surface. The fixed section 11 and the second wall surface can form a heat dissipation exhaust channel, which is conducive to the dissipation of the heat inside the disconnect structure, avoids the temperature inside the disconnect structure being too high, and further, is conducive to prolonging the service life of the disconnect structure.
[0095] In some embodiments, the mounting space further has a third wall surface and a fourth wall surface arranged 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 a cuboid-shaped mounting space.
[0096] As an example, as shown in Figure 3 , the third wall surface is provided with a third protrusion 23 protruding towards the mounting space, and the side of the fixed section 11 close to the third wall surface is limited by the third protrusion 23.
[0097] In this case, after the static contact 1 is installed on the shell 2, the fixing section 11 is located in the installation space, and the side of the fixing section 11 close to the third wall surface is limited by the third protruding part 23. The third protruding part 23 is arranged so that there is a gap between the side of the fixing section 11 close to the third wall surface and the third wall surface, and the entire side of the fixing section 11 close to the third wall surface does not come into contact with the third wall surface. The fixing section 11 and the third wall surface can form a heat dissipation exhaust channel, the cross section of the heat dissipation exhaust channel is increased, which is beneficial to the heat inside the breaking structure to be dissipated, avoids the temperature inside the breaking structure to be too high, and further, is beneficial to prolong the service life of the breaking structure.
[0098] In specific implementation, the number of the third protruding parts 23 can be multiple, so that after the static contact 1 is installed on the shell 2, the number of the third protruding parts 23 in contact with the fixing section 11 is more, the limiting area of the fixing section 11 is larger, and the firmness of the fixing section 11 arranged on the shell 2 can be ensured.
[0099] The number of the third protruding parts 23 is not specifically limited here, and the multiple third protruding parts 23 are arranged in an array on the third wall surface. At this time, it is convenient to form a linear heat dissipation exhaust channel between the two columns or two rows of third protruding parts 23, which is beneficial to the guidance of heat and the flow of heat.
[0100] Referring to Figure 3 , in specific implementation, multiple third protruding parts 23 can be arranged on the third wall surface close to the first wall surface, and the multiple third protruding parts 23 are arranged in sequence along the length direction of the fixing section 11.
[0101] Similarly, referring to Figure 4 , multiple third protruding parts 23 can also be arranged on the third wall surface close to the second wall surface, and the multiple third protruding parts 23 are arranged in sequence along the length direction of the fixing section 11.
[0102] It should be noted here that in the embodiments provided in the present application, the length direction of the fixing section 11 refers to the direction from the end of the fixing section 11 connected with the contact section 13 to the end of the fixing section 11 connected with the connecting section 12. The first wall surface, the second wall surface, the third wall surface and the fourth wall surface are all parallel to the length direction of the fixing section 11.
[0103] As another example, referring to Figure 5 and Figure 6 , the fourth wall surface is provided with a fourth protruding part 24 protruding into the installation space, and the side of the fixing section 11 close to the fourth wall surface is limited by the fourth protruding part 24.
[0104] When the static contact 1 is installed on the shell 2, the fixed section 11 is located in the installation space, and the side of the fixed section 11 close to the fourth wall surface is limited by the fourth protruding part 24. The fourth protruding part 24 is arranged to form a gap between the side of the fixed section 11 close to the fourth wall surface and the fourth wall surface, so that the entire side of the fixed section 11 close to the fourth wall surface does not contact the fourth wall surface. The fixed section 11 and the fourth wall surface can form a heat dissipation exhaust channel, which increases the cross section of the heat dissipation exhaust channel, facilitates heat dissipation inside the breaking structure, avoids high temperature in the breaking structure, and further prolongs the service life of the breaking structure.
[0105] In specific implementation, the number of fourth protruding parts 24 can be multiple. In this way, after the static contact 1 is installed on the shell 2, the number of fourth protruding parts 24 in contact with the fixed section 11 is larger, and the limiting area of the fixed section 11 is larger, which can ensure the firmness of the fixed section 11 arranged on the shell 2.
[0106] The number of fourth protruding parts 24 is not specifically limited here, and multiple fourth protruding parts 24 can be arranged in an array on the fourth wall surface. At this time, it is convenient to form a linear heat dissipation exhaust channel between adjacent two columns or two rows of fourth protruding parts 24, which is conducive to guiding heat and facilitating heat flow.
[0107] Referring to Figure 5 , in specific implementation, multiple fourth protruding parts 24 can be arranged at positions close to the first wall surface on the fourth wall surface, and the multiple fourth protruding parts 24 are arranged in sequence along the length direction of the fixed section 11.
[0108] Similarly, referring to Figure 6 , multiple fourth protruding parts 24 can also be arranged at positions close to the second wall surface on the fourth wall surface, and the multiple fourth protruding parts 24 are arranged in sequence along the length direction of the fixed section 11.
[0109] As an optional way, in combination with Figure 3 , Figure 5 and Figure 7 , the avoiding grooves 25 are arranged at positions corresponding to the third wall surface and the fourth wall surface of the installation hole.
[0110] In this way, the cross section of the heat dissipation exhaust channel at the position of the installation hole is increased, the heat dissipation exhaust channel formed between the fixed section 11 and the shell 2 is communicated with the outside, so that the heat generated by the electronic components in the breaking structure can be dissipated in time and effectively, the heat dissipation efficiency of the breaking structure is improved, the service life of the breaking structure is prolonged, and the normal work of the breaking structure is ensured.
[0111] In some embodiments, first protruding parts 21 are arranged on both sides of the threaded connection structure in the length direction of the fixed section 11.
[0112] Thus, on the one hand, after the fixed segment 11 is connected with the shell 2, the number of the first protruding parts 21 in supporting contact with the fixed segment 11 is more, the supporting contact area of the fixed segment 11 is larger, and the firmness of the fixed segment 11 arranged on the shell 2 can be ensured. On the other hand, the phenomenon that the two ends of the fixed segment 11 are inclined compared with the first wall surface under the action of the threaded connection structure is avoided, and the installation precision of the static contact 1 cannot be guaranteed.
[0113] Specifically, as shown in Figure 1 The shell 2 is also provided with a heat dissipation hole 28, and the heat dissipation hole 28 is provided with a dust screen.
[0114] At this time, the heat dissipation area is increased, the air circulation is more smooth, so that the heat generated by the electronic components in the breaking structure can be effectively dissipated in time.
[0115] The setting of the dust screen can avoid the dust in the air from entering the inside of the breaking structure, so as to avoid the pollution of the internal parts of the breaking structure and affect the normal work of the breaking structure. At the same time, the line of sight can be blocked, so that personnel cannot visually observe the internal structure of the breaking structure from the outside of the shell 2 through the heat dissipation hole 28, and the confidentiality is improved.
