Description

Technical Field

[0001] The utility model relates to the field of control equipment, in particular to an electronic equipment shell, an electronic equipment and a control cabinet thereof. Background Art

[0002] In order to realize automation, intelligence, edge computing, and establish the Internet of Things, electronic devices such as Internet of Things controllers, Internet of Things data transfer units (DTUs), digital infrastructures (DIs), and programmable logic controllers (PLCs) are widely used in production and life. These devices are referred to as electronic devices below. Electronic devices are usually installed in a control cabinet and fixed on the mounting base plate in the control cabinet or on the guide rails arranged horizontally on the mounting base plate in a back-hanging manner. The control cabinet is provided with a collection trough around the mounting base plate, resulting in limited horizontal space for the mounting base plate and the arrangement length of the electronic devices installed on the guide rails.

[0003] In order to realize more functions, the above-mentioned electronic devices need to integrate more electronic components and expand more interfaces on their circuit boards. Under the same manufacturing process, this inevitably leads to the increase in the size of the circuit board as the number of electronic components and wiring ports increases. However, due to the limited space layout in the control cabinet, the space for expanding functions by increasing the number of electronic devices or expanding their size is extremely limited.

[0004] Therefore, how to enable the control cabinet to achieve more functions at a lower cost has become a technical problem that needs to be solved urgently in this field. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model provides an electronic device housing, an electronic device and a control cabinet thereof, which can improve the space utilization rate of the control cabinet and enable the control cabinet to achieve more functions at a lower cost in the same space.

[0008] Compared with the existing solution that the length direction of the interface on the electronic device housing is consistent (parallel) with the width direction of the back of the housing, this solution sets the direction of the wiring port on the electronic device housing to intersect (perpendicular) with the width direction of the back, so that the vertical space in the control cabinet can be fully utilized, thereby breaking through the limitation that the total length of the wiring ports on all electronic device housings is less than the length of the guide rail on the control cabinet, making the total length of the wiring ports on all electronic device housings much longer than the length of the guide rail on the control cabinet, thereby providing the possibility and basis for the control cabinet to achieve (expand) more functions.

DETAILED DESCRIPTION

[0046] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0047] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present utility model. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0048] The interfaces of existing electronic devices are mainly arranged on the top surface, bottom surface or front surface (i.e., the front), and the interfaces are arranged horizontally, that is, multiple interfaces are arranged horizontally, or the arrangement direction of multiple interfaces is parallel to the guide rail. Due to the limitation of the size of the control cabinet, the length of the guide rail is limited, and it is necessary to take into account that the wires and cables can be stored in the wire trough with a large bending radius after being connected from the electronic equipment. Therefore, the electronic equipment must be set on the guide rail with sufficient space reserved for the surrounding area. This leads to the problem of insufficient space utilization of the control cabinet when the electronic equipment with the existing structure is used in the control cabinet.

[0049] Taking into account the thickness of the electronic device housing, the length of the wiring port arranged horizontally on the electronic device housing must be less than the length of the guide rail occupied by the electronic device. Even if the guide rail is covered with electronic devices, the total length of the wiring port on the electronic device is still much less than the length of the guide rail. Even if the top and bottom surfaces of the housing are fully provided with wiring ports, the total length of the wiring port is only twice the length of the guide rail. The length of the wiring port on the electronic device determines the number of wiring terminals and also limits the upper limit of the expansion function of the electronic device. To this end, the present embodiment provides an electronic device housing, an electronic device and a control cabinet, which can break through the limitation that the length of the wiring port on the electronic device in the control cabinet is less than the length of the guide rail, and make full use of the vertical space perpendicular to the guide rail, so that the length of the wiring port can reach or exceed the length of the guide rail, so that the space utilization rate of the control cabinet can be improved in a low-cost manner, and it provides the possibility and basis for the control cabinet to realize (expand) more functions.

[0050] Example:

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, an electronic device housing 10 is provided. The electronic device is installed in a control cabinet when in use. The electronic device includes two parts: the housing 10 and a hardware circuit board 20. The housing 10 of the electronic device has a mounting portion 11, a wiring port 12, and a receiving cavity for receiving the hardware circuit board 20 of the electronic device.

[0052] The housing 10 of the electronic device is usually in the shape of a cube, having an upper (top) surface, a lower (bottom) surface, a left surface, a right surface, a front (front) surface, and a rear (back) surface, a total of six end surfaces, wherein the upper (top) surface and the lower (bottom) surface are opposite in the z-axis direction, the left surface and the right surface are opposite in the y-axis direction, and the front (front) surface and the rear (back) surface are opposite in the x-axis direction.

[0053] The mounting portion 11 is located on the back of the housing 10, and the mounting portion 11 is used to be detachably connected to the control cabinet. After the cabinet door of the control cabinet is opened, the mounting base plate inside it directly faces the direction of the cabinet door opening. A plurality of parallel guide rails are arranged from top to bottom on the mounting base plate, and the guide rails are usually arranged horizontally, that is, in the y-axis direction in the figure. The spacing between two adjacent guide rails can be appropriately adjusted according to the requirements of electronic equipment and cable storage.

[0054] At least one end surface of the electronic device housing 10 is provided with a wiring port 12 connected to the accommodating cavity, so that the wiring terminals 30 at the edge of the hardware circuit board 20 in the accommodating cavity can be exposed from the wiring port 12. It should be noted that the wiring port 12 is usually used to expose the wiring terminals for connecting external cables, and can also be used to set components such as antenna bases and indicator lights. The wiring port can accommodate the external interface of any component, that is, the controller can carry various interfaces, mainly by adjusting the shape and size of different wiring holes to adapt to different functions.

[0055] The wiring port 12 is located at least on one of the top surface and the bottom surface of the housing 10. It is easy to understand that the wiring port 12 can be set on the top surface, the bottom surface, or both of the top and bottom surfaces of the housing 10. When the wiring port 12 is set on the top surface, its opening faces upward; when the wiring port 12 is set on the bottom surface, its opening faces downward.

[0056] Compared with the traditional horizontally arranged wiring port 12, in the length direction of the wiring port, one end of the wiring port 12 in this embodiment extends toward the mounting portion 11, and the other end of the wiring port 12 extends away from the mounting portion 11, and the width of the back of the shell is less than the length of the wiring port. That is, when the wiring port 12 is arranged on the top surface and / or the bottom surface of the shell 10, its extension direction is from the back to the front, or from the front to the back. In other words, the extension direction of the wiring port 12 on the electronic device shell 10 in this embodiment is vertically arranged relative to the guide rail on the mounting base plate in the control cabinet, and the hardware circuit board 20 in the shell 10 is also vertically arranged, so that when the vertically arranged wiring port 12 accommodates multiple wiring terminals 30, the arrangement direction of the multiple terminals is also along the extension direction of the wiring port 12.

[0057] It should be noted that the wiring port is not limited to being used to set the same type of wiring terminals, but can also be used to arrange different types of wiring terminals. The shape of the wiring port is not limited to a rectangle, and it can also be formed by a plurality of sub-wiring ports of different shapes arranged linearly in the extension direction, and is not limited to one row, but can also be two or more rows.

[0058] This electronic device housing 10 with a vertically arranged wiring port 12, after being installed in a control cabinet, can utilize the space in the cabinet perpendicular to the installation base plate, and occupy less space on the guide rail while accommodating the same number of wiring terminals 30, so that the guide rail in the control cabinet can free up more space to install more electronic equipment, that is, electronic and / or electrical devices, or reserve space for subsequent expansion equipment, or a smaller control cabinet can be used, thereby reducing costs and occupied space. That is, this solution sets the direction of the wiring port on the electronic device housing to intersect (perpendicular) with the width direction of the back, so that the vertical space in the control cabinet can be fully utilized, thereby breaking through the limitation that the total length of the wiring ports on the housings of all electronic devices is less than twice the length of the guide rail on the control cabinet, and fully utilizing the vertical space perpendicular to the guide rail. After the wiring ports are fully arranged on the top and bottom surfaces at the same time, it can exceed twice the length of the guide rail, thereby providing the possibility and basis for the control cabinet to realize (expand) more functions.

[0059] It should be noted that the top and bottom surfaces of the electronic device housing 10 are not absolutely horizontal or flat surfaces, but may have a slope with a certain inclination (tilted left and right, or tilted front and back), may have a curved surface with a certain shape, or may be composed of multiple planes of different heights (with Fig.10 As shown), and connected inclined surfaces. In short, the surface on the housing 10 that is located at the top and facing upward is regarded as the top surface, and the surface on the housing 10 that is located at the bottom and facing downward is regarded as the bottom surface. Among them, when the top and bottom surfaces of the housing 10 have one side in the front-to-back direction, that is, the x-axis direction, which is tilted downward or upward, the electronic device housing 10 can be suitable for certain unconventional circuit boards, such as trapezoidal or triangular circuit boards. When the top and bottom surfaces of the housing 10 have one side in the left-to-right direction, that is, the y-axis direction, which is tilted downward or upward, or is a stepped surface, the wiring port of the electronic device housing 10 can be adapted to some unconventionally arranged wiring terminals, such as oblique wiring terminals (refer to Fig.10 ).

[0060] In some embodiments, Figure 1 and Figure 2 As shown, the housing 10 includes a first shell 110 and a second shell 120 that can be relatively combined to form a receiving cavity. The first shell 110 and the second shell 120 are detachably connected at the joint, and only the internal thread column is shown in the figure to cooperate with the bolt thread connection.

[0061] Specifically, the first housing 110 has a first opening 111 and a first rear side wall 112. The end surface of the first housing 110 opposite to the first opening 111 forms the top surface of the housing 10, that is, the first opening 111 faces downward, the top surface of the first housing 110 is the top surface of the housing 10, and the wiring port 12 is arranged on the top surface of the first housing 110. Among them, the first rear side wall 112 (the lower side) constitutes part of the first opening 111.

[0062] Similarly, the second housing 120 has a second opening 121 and a second rear side wall 122. The end surface of the second housing 120 opposite to the second opening 121 forms the bottom surface of the housing 10, that is, the second opening 121 faces upward, the bottom surface of the second housing 120 is the bottom surface of the housing 10, and the wiring port 12 is also provided on the bottom surface of the second housing 120. Among them, the second rear side wall 122 (the lower side) constitutes part of the second opening 121.

[0063] The first opening 111 and the second opening 121 are aligned with each other, and the first rear side wall 112 and the second rear side wall 122 form the back of the housing 10 at the aligned position. It is easy to understand that the mounting portion 11 can be arranged on the first rear side wall 112 of the first housing 110, or on the second rear side wall 122 of the second housing 120, or partially on the first rear side wall 112 and partially on the second rear side wall 122, and the mounting portion 11 is completed when the first rear side wall 112 and the second rear side wall 122 are aligned. According to the composition of the housing 10, the mounting portion 11 can be flexibly arranged on one or more components thereof without limitation.

[0064] The shell 10 of the electronic device with the above structure can also be regarded as that the surface where the first shell 110 and the second shell 120 are located at the joint (which can be a plane, a curved surface, or a combination of multiple surfaces) is located between the top surface and the bottom surface of the shell 10, and divides the shell 10 into two parts, the upper part is the first shell 110, and the lower part is the second shell 120.

[0065] In some embodiments, Figure 4 and Figure 5 As shown, the electronic device housing 10 includes a top panel 210 and a bottom panel 220 that are arranged opposite to each other, and a front half shell 230 and a rear half shell 240 that are located between the top panel 210 and the bottom panel 220. The housing 10 is surrounded by the top panel 210, the bottom panel 220, the front half shell 230 and the rear half shell 240, and forms a receiving cavity in which the hardware circuit board 20 of the electronic device can be placed.

[0066] Specifically, the front half shell 230 includes a front panel 231 and front side panels 232 connected to and opposite to both sides of the front panel 231. The rear half shell 240 includes a rear panel 241 and rear side panels 242 connected to and opposite to both sides of the rear panel 241.

[0067] The two front side plates 232 of the front half shell 230 and the two rear side plates 242 of the rear half shell 240 are matched to form a top opening 14 and a bottom opening 15. The top opening 14 faces upward, and the bottom opening 15 faces downward. The contour of the top opening 14 is adapted to the top panel 210, and the top panel 210 is detachably disposed in the top opening 14. The contour of the bottom opening 15 is adapted to the bottom panel 220, and the bottom panel 220 is detachably disposed in the bottom opening 15.

[0068] The housing 10 is surrounded by the top panel 210, the bottom panel 220, the front half shell 230 and the rear half shell 240. The top panel 210 forms the top surface of the housing 10, and the bottom panel 220 forms the bottom surface of the housing 10. It can be understood that the wiring port 12 can be set on the top panel 210, can also be set on the bottom panel 220, and can also be set on both the top panel 210 and the bottom panel 220. The front panel 231 in the front half shell 230 forms the front surface of the housing 10, and the rear panel 241 in the rear half shell 240 forms the back surface of the housing 10. The two joints between the two front side panels 232 and the two rear side panels 242 are respectively located on the left and right surfaces of the housing 10, and the joints extend in the up-down direction.

[0069] It should be noted that when the top panel 210 is mounted on the top opening 14, or when the bottom panel 220 is mounted on the bottom opening 15, the extension direction of the wiring port 12 should be directed from the front panel 231 to the rear panel 241, or from the rear panel 241 to the front panel 231, that is, the extension direction of the wiring port 12 on the housing 10 (relative to the horizontally arranged guide rail) is vertically arranged. The mounting portion 11 is arranged on the back of the housing 10, that is, on the rear panel 241. The front panel 231 and the rear panel 241 in this embodiment are only for the convenience of description, and do not strictly limit the installation position relationship between them and the control cabinet. In some embodiments, the front panel 231 and the rear panel 241 can be interchangeable, or the mounting portion 11 is arranged on both the front panel 231 and the rear panel 241, so that there is no need to consider the direction during installation, reducing the operation requirements for the installer. At the same time, the front panel 231 and the rear panel 241 can also adopt the same structure to improve the versatility of parts.

[0070] In some embodiments, Figure 6 As shown, the electronic device housing 10 includes a top panel 210 and a bottom panel 220 that are arranged opposite to each other, and a left half shell 310 and a right half shell 320 that are located between the top panel 210 and the bottom panel 220. The housing 10 is surrounded by the top panel 210, the bottom panel 220, the left half shell 310 and the right half shell 320, and forms a receiving cavity in which the hardware circuit board 20 of the electronic device can be placed.

[0071] Specifically, the left half shell 310 includes a left side panel 311, and left side panels 312 respectively connected to and arranged opposite to the two sides of the left side panel 311. The right half shell 320 includes a right side panel 321, and right side panels 322 respectively connected to and arranged opposite to the two sides of the right side panel 321. The left side panel 311 and the right side panel 321 are arranged opposite to each other, and the arrangement direction of the left side panel 311 and the right side panel 321 is the same as the extension direction of the wiring port 12.

[0072] The left half shell 310 and the right half shell 320 are relatively matched. The left half shell 310 and the right half shell 320 can adopt an asymmetric structure or a symmetric structure, that is, the whole can be symmetrically arranged about the matching part (surface), or the matching surface can be biased to one of them to form an asymmetric structure. When the left half shell 310 and the right half shell 320 adopt an asymmetric structure, the main difference lies in the width of the left panel 312 and the width of the right panel 322, that is, the distance from the matching part (surface) of the left panel 312 to the left panel 311 is different from the distance from the matching part (surface) of the right panel 322 to the right panel 321. In addition, a mounting structure for mounting the hardware circuit board 20 of the electronic device is provided around the matching part of the left half shell 310 or the right half shell 320, such as a plug-in slot, an internal threaded column, etc., and some similar structures such as the plug-in slot can also be provided on the top panel and the bottom panel. After the hardware circuit board 20 is installed, the circuit board 20 is close to the joint and separates the left half shell 310 and the right half shell 320 into two spaces of a larger volume and a smaller volume at the joint (surface).

[0073] The hardware circuit board 20 of the electronic device has a front side and a back side, wherein the circuit components arranged on the front side and the back side are slightly different, wherein the circuit components arranged on one side will occupy more space (the height space perpendicular to the surface of the circuit board 20), while the pins of the circuit components on the other side are mostly pins of the circuit components, so the space occupied is less. By adopting an asymmetric setting, it is also possible to select the left half shell 310 and the right half shell 320 of appropriate width for combination and use according to the size of the circuit components on different electronic devices, wherein the larger half shell can be used as a universal part, and the smaller half shell adopts multiple specifications, so as to be selected according to the situation, thereby saving production costs.

[0074] More specifically, the two left panels 312 of the left half shell 310 and the two right panels 322 of the right half shell 320 are matched, and after the matching, a top opening 14 and a bottom opening 15 are formed. The top opening 14 faces upward, and the bottom opening 15 faces downward. The contour of the top opening 14 is adapted to the top panel 210, and the top panel 210 is detachably disposed in the top opening 14. The contour of the bottom opening 15 is adapted to the bottom panel 220, and the bottom panel 220 is detachably disposed in the bottom opening 15.

[0075] The housing 10 is formed by the top panel 210, the bottom panel 220, the left half shell 310 and the right half shell 320, wherein the top panel 210 forms the top surface of the housing 10 and the bottom panel 220 forms the bottom surface of the housing 10. It can be understood that the wiring port 12 can be provided on the top panel 210, can also be provided on the bottom panel 220, and can also be provided on both the top panel 210 and the bottom panel 220.

[0076] The two left panels 312 and the two right panels 322 corresponding thereto are respectively matched at two locations, and after being matched, two opposite panels are formed respectively, the top panel 210 and the bottom panel 220 are both located between the two panels, and the extension direction of the wiring port 12 on the top panel 210 and the bottom panel 220 is from one panel to the other panel, so the installation portion 11 provided on any one of the two panels can serve as the back of the housing 10, and no limitation is made here. In some embodiments, the installation portion 11 is provided on both the two left panels 312 and the two right panels 322, so that the direction does not need to be considered during installation, reducing the operation requirements for the installer.

[0077] In some embodiments, some electronic device housings 10 adopt a detachable structure of the top panel 210 and the bottom panel 220, that is, the components of some electronic device housings 10 will form a top opening 14 and a bottom opening 15 after assembly, so as to further detachably install the top panel 210 and the bottom panel 220. The electronic device housing 10 with such a structure can be designed with wiring ports and other functional ports of different models and sizes according to the types of different electronic devices, such as antenna interfaces, heat dissipation ports, indicator light ports, etc., as well as their distribution positions.

[0078] Specifically, Figure 7 and Figure 8 As shown, a card slot 16 is provided on the inner wall of the top opening 14 and the bottom opening 15 which will be formed after the components of the partial electronic device housing 10 are assembled. The card slot 16 can be a continuously arranged annular groove, or can be intermittently arranged. The groove width of the card slot 16 is adapted to the corresponding top panel 210 and bottom panel 220 so that the edges of the top panel 210 and the bottom panel 220 can be inserted into the card slot 16 to achieve card connection.

[0079] Depending on the control type, the size of the hardware circuit board 20 is slightly different. When the length of the hardware circuit board 20 vertically arranged in the electronic device housing 10 is much smaller than the spacing between the top panel 210 and the bottom panel 220 in the vertical direction, the connection ports 12 on the top panel 210 and the bottom panel 220 must be far away from the connection terminals 30 at the edge of the hardware circuit board 20. Or use an electronic device housing 10 with a smaller height, which will increase the cost. Therefore, in some embodiments, in order to improve the versatility of the electronic device housing 10 and reduce the number of (different structural) parts between multiple models, multiple (layers) of card slots 16 are provided on the inner wall of the top opening 14 and the bottom opening 15 formed by the parts of some electronic device housings 10 after assembly, at least two (layers) are provided, and the two (multiple) (layers) of card slots 16 are sequentially arranged from the inside to the outside along the opening direction. When in use, according to the size of the electronic device hardware circuit board 20, the top panel 210 and the bottom panel 220 are selectively inserted into the corresponding card slots 16 for card connection. In this way, the applicability of the electronic device housing 10 can be greatly improved. For example, two inner and outer (layer) card slots 16 are respectively provided on the top opening 14 and the bottom opening 15, so that four electronic devices of different specifications can be adapted.

[0080] In some embodiments, the top panel or the bottom panel is provided with a sleeve edge for fitting with the inner wall of the top opening or the inner wall of the bottom opening, and the sleeve edge is slightly smaller than the contour of the top panel or the bottom panel to leave a portion of the edge to fit into the slot. Figure 8 As shown, after the edge of the top panel is inserted into the slot, its sleeve edge fits against the inner wall of the top opening, thereby improving the connection strength.

[0081] In some embodiments, in some electronic device housings 10 with a detachable top panel 210 and bottom panel 220, the top opening 14 and the bottom opening 15 are formed by fitting two parts together, for example, the front side panel 232 of the front half shell 230 and the rear side panel 242 of the rear half shell 240 are fitted together, and the left side panel 312 of the left half shell 310 and the right side panel 322 of the right half shell 320 are fitted together, and these parts are detachably connected at the fitting parts, such as threaded connection (see Figure 4-Figure 6 ), snap-on connection structure (see Figure 8 ), one or more of fastener connection, mortise and tenon connection structure and nested connection structure.

[0082] In some embodiments, Figure 8 As shown, the front half shell and the rear half shell are provided with a detachable connection structure at the joint, including a buckle provided on one of the front side plate 232 and the rear side plate 242, and a buckle groove provided on the other of the front side plate 232 and the rear side plate 242. The front half shell and the rear half shell are connected by the cooperation of the buckle and the buckle groove.

[0083] In some embodiments, Figure 1 and 8 As shown, the mounting portion 11 includes a mounting groove, which extends to both sides and passes through both sides of the housing 10. The extension length of the mounting groove is the width of the back of the housing, and the extension length of the mounting groove is less than the length of the wiring port. That is, the mounting groove extends along the left and right directions on the back of the electronic device housing 10 and passes through the left and right sides of the housing 10, so that when the guide rail is installed on the guide rail of the control cabinet, it can pass through the mounting groove to achieve fixation. Specifically, the mounting groove can adopt a dovetail groove, or a similar structure in which the groove opening is narrower than the groove bottom, so that the guide rail will not fall off after passing through the mounting groove horizontally.

[0084] In some embodiments, the electronic device housing 10 is formed by assembling multiple components, such as Figure 1 As shown in , the mounting groove is disposed between the first shell 110 and the second shell 120, and one groove wall of the mounting groove is the plane where the mating part is located.

[0085] Similarly, in some embodiments, as shown in FIG. 1 , the first shell 110 and the second shell 120 also adopt a similar detachable connection method at the mating point, such as one or more of a threaded connection structure, a snap connection structure, a fastener connection, a mortise and tenon connection structure, and a nested connection structure.

[0086] Specifically, Figure 1 In the embodiment, the detachable connection structure includes a screw hole provided on one of the first shell 110 and the second shell 120 , and a threaded fastener (not shown) for fixing the first shell 110 and the second shell 120 .

[0087] In some embodiments, for the convenience of processing, the electronic device housing can be made by processing sheet metal. According to the actual situation, the housing includes at least two sheet metal parts, usually two, three or four sheet metal parts. These sheet metal parts are spliced ​​and enclosed to form a receiving cavity. The wiring port 12 is formed on one or two sheet metal parts.

[0088] For example, in Figure 9a The scheme in which the housing is spliced ​​by four sheet metal parts is shown, wherein two sheet metal parts respectively form the top panel and the bottom panel of the housing. Two wiring ports 12 are respectively arranged on the two sheet metal parts forming the top panel and the bottom panel, which can be formed by punching and cutting. Among them, the other two sheet metal parts are bent to form two connected panels of the housing, specifically, one sheet metal part is bent 90 degrees to form the front panel and the left panel, and the other sheet metal part is bent 90 degrees to form the rear panel and the right panel, wherein the sheet metal part forming the rear panel is provided with a mounting fastening hole or an L-shaped hanging hole, and the screw head of the length is exposed on the guide rail, and the hanging hole is used to fix the housing on the screw head of the guide rail.

[0089] For example, in Figure 9b-9eIn the figure, the scheme that the shell is spliced ​​by two sheet metal parts is shown respectively. Each sheet metal part can form two adjacent panels or three panels of the shell. The specific configuration can be flexibly set according to actual needs and is not strictly limited here. Figure 9b-9e Only a few of these cases are shown as examples for illustration, but the total number of panels formed by the two sheet metal parts is still 6, which remains unchanged. The two sheet metal parts are provided with folded edges at the connection, and threaded screws are inserted and / or nested and abutted after the folded edges overlap with the edges forming the panels, and the two are fastened and connected in combination.

[0090] The top panel and the bottom panel of the shell can be formed on the same sheet metal part or on two sheet metal parts. That is, when the top panel and the bottom panel of the shell are on the same sheet metal part, the wiring port 12 is formed by opening holes at the corresponding top panel and bottom panel of the sheet metal part; when the top panel and the bottom panel of the shell are on two sheet metal parts, the wiring port 12 is formed by opening holes at the corresponding top panel and bottom panel of the two sheet metal parts.

[0091] In some embodiments, the mounting portion 11 can be an L-shaped punched hole on the back of the shell (i.e., the rear panel) that can cooperate with the connector on the guide rail; it can also be a threaded hole or a fastening hole for installing the guide rail base; it can also be a slit (gap), notch, protrusion, etc. that surrounds the back (around the rear panel) and can be fixed with the mounting base clamp, such as the splicing gaps or protrusions formed around the back of the shell after the sheet metal is spliced.

[0092] At the same time, this embodiment Fig.10 and Fig.11 In the present invention, there is also provided an electronic device including a circuit board 20 and the electronic device housing 10 in the above embodiment, wherein the circuit board 20 is located in the accommodating cavity and is arranged along the extension direction of the wiring port 12; the circuit board 20 is provided with a plurality of wiring terminals 30 on one side close to the wiring port 12, and the ports of the wiring terminals 30 are exposed in the wiring port 12.

[0093] In addition, this embodiment also provides a control cabinet, such as Figure 3 As shown, the cabinet includes a cabinet body and a cabinet door (not shown); the cabinet body has an opening and a mounting base plate opposite to the opening, and the cabinet door is arranged on the opening so as to be openable and closable. A transverse guide rail 40 is arranged on the mounting base plate, and one or more electronic devices are arranged on the guide rail. Only one electronic device is used as an example in the figure, and the housing of the electronic device is connected to the guide rail through the mounting groove on the back.

[0094] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
