DETAILED DESCRIPTION

[0047] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which like reference numerals designate identical or similar elements throughout the several views. Based on the embodiments in the embodiments, the purpose is to explain the present application, and it cannot be understood as a limitation of the present application.

[0048] "one embodiment" or "an embodiment" or "example" or "exemplary" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

[0049] The interface of the existing electronic device is mainly arranged on the top surface or the bottom surface or the front surface (i.e., the front surface), and the interface is arranged transversely, that is, a plurality of interfaces are arranged in the transverse direction, or the arrangement direction of the plurality of interfaces is parallel to the guide rail. Due to the size limitation of the control cabinet, the length of the guide rail is limited, and the space around the electronic device on the guide rail must be reserved to accommodate the cables in the wire slot with a large bending radius after the cables are connected to the electronic device. Therefore, when the electronic device of the existing structure is applied in the control cabinet, the problem of insufficient space utilization of the control cabinet will be encountered.

[0050] In addition, considering the thickness of the electronic device shell, the length of the wiring port arranged transversely on the electronic device shell must be less than the length of the guide rail occupied by the electronic device. Even if the electronic device is fully laid on the guide rail, 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 surface and the bottom surface of the shell are provided with full wiring ports, the total length of the wiring ports is only twice the length of the guide rail. The length of the wiring port on the electronic device determines the number of terminal connectors and limits the upper limit of the expansion function of the electronic device. Therefore, the present embodiment provides an electronic device shell, 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, fully utilize 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, thereby improving the space utilization of the control cabinet at low cost and providing the possibility and basis for the control cabinet to realize (expand) more functions.

[0051] Embodiment:

[0052] As shown in FIGS. 1, 2 and 3, an electronic device shell 10 is provided, which is installed in a control cabinet when in use, and the electronic device includes two parts of the shell 10 and a hardware circuit board 20. The shell 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.

[0053] The shell 10 of the electronic device is usually cubic, 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.

[0054] The mounting portion 11 is located on the back of the shell 10, and is used for detachable connection with the control cabinet. When the door of the control cabinet is opened, the mounting plate inside the control cabinet directly faces the opening direction of the door, and a plurality of parallel rails are arranged on the mounting plate from top to bottom. The rails are usually arranged horizontally, i.e. in the y-axis direction in the figure. According to the requirements of the electronic device and the cable storage, the spacing between two adjacent rails can be adjusted appropriately.

[0055] At least one end surface of the electronic device shell 10 is provided with a connection port 12 in communication with the accommodation cavity, so that the connection terminals 30 at the edge of the hardware circuit board 20 in the accommodation cavity can be exposed from the connection port 12. It should be noted that, generally, the connection port 12 is used to expose the connection terminals for connection with external cables, and in addition, can be used to arrange antenna bases, indicator lights and other elements. The connection port can accommodate the external interface of any element, that is, the controller can carry various interfaces, mainly by adjusting the shape and size of different connection holes to adapt to different functions.

[0056] The connection port 12 is arranged on at least one of the top surface and the bottom surface of the shell 10. It is easy to understand that the connection port 12 can be arranged on the top surface of the shell 10, or on the bottom surface, or on both the top surface and the bottom surface of the shell 10. When the connection port 12 is arranged on the top surface, the opening thereof faces upward; when the connection port 12 is arranged on the bottom surface, the opening thereof faces downward.

[0057] Compared with the conventional transversely arranged connection port 12, in the embodiment, one end of the connection port 12 extends toward the mounting portion 11 in the length direction of the connection port, the opposite end of the connection port 12 extends away from the mounting portion 11, and the width of the back surface of the shell is smaller than the length of the connection port. That is, when the connection port 12 is arranged on the top surface and / or the bottom surface of the shell 10, the extension direction thereof is from the back surface to the front surface, or from the front surface to the back surface. That is to say, the extension direction of the connection port 12 on the electronic device shell 10 in the embodiment is vertically arranged with respect to the rails on the mounting 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 connection port 12 accommodates a plurality of connection terminals 30, the arrangement direction of the plurality of terminals is also along the extension direction of the connection port 12.

[0058] It should be noted that the connection port is not limited to arranging the same type of connection terminal, but can also be used to arrange different types of connection terminals. The shape of the connection port is not limited to a rectangle, but can also be formed by linearly arranging a plurality of sub-connection ports of different shapes in the extension direction, and is not limited to one row, but can also be two rows or more.

[0059] The vertically arranged electronic device shell 10 can utilize the space perpendicular to the installation bottom plate in the cabinet after being installed in the cabinet, and can accommodate the same number of terminal blocks 30 while occupying less space of the guide rail, so that more space of the guide rail in the cabinet can be left for installing more electronic devices, i.e., electronic and / or power devices, or reserving space for subsequent expansion devices, or a smaller cabinet can be used, thereby reducing cost and space occupation. That is, the direction of the terminal block on the electronic device shell is arranged to intersect (perpendicularly) the width direction of the back, so that the vertical space in the cabinet can be fully utilized, thereby breaking the limitation that the total length of all terminal blocks on the electronic device shell is less than twice the length of the guide rail on the cabinet, fully utilizing the vertical space perpendicular to the guide rail, and breaking the limitation that the length of the guide rail is twice after arranging the terminal blocks on the top surface and the bottom surface, thereby providing the possibility and basis for realizing (expanding) more functions of the cabinet.

[0060] It should be noted that the top surface and the bottom surface of the electronic device shell 10 are not necessarily horizontal or flat surfaces, but can be inclined surfaces (inclined left and right, or inclined front and back), curved surfaces with certain shapes, or composed of multiple different height flat surfaces (as shown in FIG. 10) and connecting inclined surfaces. In general, the surface on the top of the shell 10 is regarded as the top surface, and the surface on the bottom of the shell 10 is regarded as the bottom surface. When the top surface and the bottom surface of the shell 10 are inclined downward or upward on one side in the front-back direction, i.e., the x-axis direction, the electronic device shell 10 can be adapted to some irregular circuit boards, such as trapezoidal or triangular circuit boards. When the top surface and the bottom surface of the shell 10 are inclined downward or upward on one side in the left-right direction, i.e., the y-axis direction, or are stepped surfaces, the terminal blocks of the electronic device shell 10 can be adapted to some irregularly arranged terminal blocks, such as inclined terminal blocks (see FIG. 10).

[0061] In some embodiments, as shown in FIGS. 1 and 2, the shell 10 includes a first shell 110 and a second shell 120 that can be relatively closed together and form a receiving cavity. The first shell 110 and the second shell 120 are detachably connected at the closure, and only internal threaded columns are shown in the figure to cooperate with bolt threaded connection.

[0062] Specifically, the first shell 110 has a first opening 111 and a first rear side wall 112. The end surface of the first shell 110 opposite to the first opening 111 forms the top surface of the shell 10, that is, the first opening 111 faces downward, the top surface of the first shell 110 is the top surface of the shell 10, and the terminal block 12 is arranged on the top surface of the first shell 110. The first rear side wall 112 (lower side) constitutes part of the first opening 111.

[0063] Similarly, the second housing 120 has a second opening 121 and a second back side wall 122. An end face of the second housing 120 opposite to the second opening 121 forms a bottom face of the outer shell 10, that is to say, the second opening 121 faces upward, the bottom face of the second housing 120 is the bottom face of the outer shell 10, and the terminal port 12 is further arranged on the bottom face of the second housing 120. The second back side wall 122 (lower side) constitutes part of the second opening 121.

[0064] The first opening 111 and the second opening 121 are opposite and abut at the first back side wall 112 and the second back side wall 122, which form a back face of the outer shell 10. It is easy to understand that the mounting portion 11 can be arranged on the first back side wall 112 of the first housing 110, or on the second back side wall 122 of the second housing 120, or partially on the first back side wall 112 and partially on the second back side wall 122, and constitutes a complete mounting portion 11 when the first back side wall 112 and the second back side wall 122 abut. According to the composition of the outer shell 10, the mounting portion 11 can be flexibly arranged on one or more components, without limitation.

[0065] The outer shell 10 of the electronic device with the above structure can also be regarded as that the face (which can be a plane, a curved surface, or a combination of multiple faces) where the first housing 110 and the second housing 120 abut is located between the top face and the bottom face of the outer shell 10, and divides the outer shell 10 into an upper part and a lower part, the upper part being the first housing 110 and the lower part being the second housing 120.

[0066] In some embodiments, as shown in FIGS. 4 and 5, the outer shell 10 of the electronic device includes a top panel 210 and a bottom panel 220 arranged opposite to each other, and a front half housing 230 and a back half housing 240 located between the top panel 210 and the bottom panel 220. The top panel 210, the bottom panel 220, the front half housing 230, and the back half housing 240 enclose the outer shell 10 and form a containing cavity in which the hardware circuit board 20 of the electronic device can be placed.

[0067] Specifically, the front half housing 230 includes a front panel 231 and two front side panels 232 respectively connected to two sides of the front panel 231 and arranged opposite to each other. The back half housing 240 includes a back panel 241 and two back side panels 242 respectively connected to two sides of the back panel 241 and arranged opposite to each other.

[0068] The two front side panels 232 of the front half housing 230 and the two back side panels 242 of the back half housing 240 abut, and form opposite top and bottom openings 14 and 15 after abutting. The top opening 14 faces upward, and the bottom opening 15 faces downward. The top opening 14 is adapted to the top panel 210, and the top panel 210 is detachably arranged in the top opening 14. The bottom opening 15 is adapted to the bottom panel 220, and the bottom panel 220 is detachably arranged in the bottom opening 15.

[0069] The top panel 210 forms a top surface of the housing 10, and the bottom panel 220 forms a bottom surface of the housing 10. It should be understood that the wiring port 12 can be arranged on the top panel 210, or on the bottom panel 220, or on both the top panel 210 and the bottom panel 220. The front panel 231 of the front half-shell 230 forms a front surface of the housing 10, and the rear panel 241 of the rear half-shell 240 forms a rear surface of the housing 10. The two hinging positions between the two front side panels 232 and the two rear side panels 242 are respectively located on the left surface and the right surface of the housing 10, and extend in the up-down direction.

[0070] 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 extending 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, i.e. the extending 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 rear surface of the housing 10, i.e. on the rear panel 241. The front panel 231 and the rear panel 241 in the present embodiment are only for the convenience of description, and are not strictly limited to the mounting position relationship with the control cabinet. In some embodiments, the front panel 231 and the rear panel 241 can be interchanged, or the mounting portion 11 can be arranged on both the front panel 231 and the rear panel 241, so that the direction does not need to be considered during installation, and the operation requirement of the installer is reduced. At the same time, the front panel 231 and the rear panel 241 can also adopt the same structure, and the universality of the parts is improved.

[0071] In some embodiments, as shown in FIG. 6, the electronic device housing 10 includes the top panel 210 and the bottom panel 220 arranged oppositely, and the left half-shell 310 and the right half-shell 320 arranged 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 containing cavity in which the hardware circuit board 20 of the electronic device can be placed.

[0072] Specifically, the left half-shell 310 includes the left side panel 311, and the left side plates 312 connected to the two sides of the left side panel 311 and arranged oppositely. The right half-shell 320 includes the right side panel 321, and the right side plates 322 connected to the two sides of the right side panel 321 and arranged oppositely. The left side panel 311 and the right side panel 321 are arranged oppositely, and the arrangement direction of the left side panel 311 and the right side panel 321 is the same as the extending direction of the wiring port 12.

[0073] The left half shell 310 and the right half shell 320 are relatively combined, and 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 hinge (plane), or the hinge and the plane can be inclined to one side to form an asymmetric structure. When the left half shell 310 and the right half shell 320 adopt an asymmetric structure, the main difference is the width of the left side plate 312 and the width of the right side plate 322, that is, the distance from the hinge (plane) of the left side plate 312 to the left side panel 311 is not equal to the distance from the hinge (plane) of the right side plate 322 to the right side panel 321. And around the hinge of the left half shell 310 or the right half shell 320, mounting structures for mounting the hardware circuit board 20 of the electronic device are provided, such as plug-in slots, internally threaded columns, etc. Similarly, some structures such as plug-in slots can also be provided on the top panel and the bottom panel. When the hardware circuit board 20 is installed, the circuit board 20 is close to the hinge and separates the left half shell 310 and the right half shell 320 into two spaces with different volumes on the hinge (plane).

[0074] The hardware circuit board 20 of the electronic device has a front surface and a back surface, and the circuit components arranged on the front surface and the back surface are slightly different. The one surface is distributed with circuit components which occupy more space (height space perpendicular to the surface of the circuit board 20), and the other surface is mainly the pins of the circuit components, so it occupies less space. By adopting an asymmetric arrangement, appropriate widths of the left half shell 310 and the right half shell 320 can be selected 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 general part, and the smaller half shell can be used in multiple specifications to be selected according to the situation, thereby saving production costs.

[0075] More specifically, the two left side plates 312 of the left half shell 310 and the two right side plates 322 of the right half shell 320 are relatively combined, and form opposite top openings 14 and bottom openings 15 after being combined. The top opening 14 faces upward, and the bottom opening 15 faces downward. The profile of the top opening 14 is adapted to the top panel 210, and the top panel 210 is detachably arranged in the top opening 14. The profile of the bottom opening 15 is adapted to the bottom panel 220, and the bottom panel 220 is detachably arranged in the bottom opening 15.

[0076] The above-mentioned outer shell 10 is surrounded by the top panel 210, the bottom panel 220, the left half shell 310 and the right half shell 320, and the top panel 210 forms the top surface of the outer shell 10, and the bottom panel 220 forms the bottom surface of the outer shell 10. It can be understood that the wiring port 12 can be arranged on the top panel 210, or arranged on the bottom panel 220, or arranged on both the top panel 210 and the bottom panel 220.

[0077] The two left side plates 312 and the two right side plates 322 are respectively hinged at two positions and form two opposite panels after being hinged, and the top panel 210 and the bottom panel 220 are located between the two panels, and the extension direction of the connecting port 12 on the top panel 210 and the bottom panel 220 is from one panel to the other panel, so that the mounting portion 11 arranged on any one of the two panels can be used as the back of the shell 10, which is not limited here. In some embodiments, the mounting portion 11 is arranged on both the two left side plates 312 and the two right side plates 322, so that the direction does not need to be considered during installation, and the operation requirement of the installer is reduced.

[0078] In some embodiments, some electronic device shells 10 adopt a detachable structure of the top panel 210 and the bottom panel 220, that is, some components of the electronic device shell 10 form the top opening 14 and the bottom opening 15 after assembly, so as to further detachably mount the top panel 210 and the bottom panel 220. The electronic device shell 10 with such a structure can design different sizes of connecting ports and other functional ports according to different types of electronic devices, such as antenna interfaces, heat dissipation ports, indicator light ports, etc., and their distribution positions.

[0079] Specifically, as shown in FIGS. 7 and 8, the inner wall of the top opening 14 and the bottom opening 15 formed after assembly of some components of the electronic device shell 10 is provided with a clamping groove 16, which can be a continuous annular groove or an intermittent distributed groove, and the groove width of the clamping groove 16 is matched with the corresponding top panel 210 and bottom panel 220, so that the edge of the top panel 210 and the bottom panel 220 can be inserted into the clamping groove 16 to realize clamping.

[0080] According to the difference of control type, the size of the hardware circuit board 20 is slightly different. When the length of the hardware circuit board 20 arranged vertically in the electronic device shell 10 in the vertical direction is much smaller than the distance between the top panel 210 and the bottom panel 220, the wiring port 12 on the top panel 210 and the bottom panel 220 must be far away from the wiring terminal 30 at the edge of the hardware circuit board 20. Either a smaller height electronic device shell 10 is used, which will increase the cost. Therefore, in some embodiments, in order to improve the versatility of the electronic device shell 10 and reduce the number of parts between different models (different structures), a plurality of (layers) of clamping grooves 16 are arranged on the inner wall of the top opening 14 and the bottom opening 15 formed after the assembly of some parts of the electronic device shell 10. At least two (layers) of clamping grooves 16 are arranged in sequence from inside to outside along the opening direction. 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 clamping grooves 16 for clamping. In this way, the applicability of the electronic device shell 10 can be greatly improved. For example, if two (layers) of clamping grooves 16 are arranged on the inner wall of the top opening 14 and the bottom opening 15 respectively, then four different specifications of electronic devices can be adapted.

[0081] In some embodiments, a sleeve edge is arranged on the top panel or the bottom panel for fitting the inner wall of the top opening or the bottom opening. The sleeve edge is slightly smaller than the contour of the top panel or the bottom panel, so as to leave part of the edge clamped into the clamping groove. As shown in FIG. 8, after the edge of the top panel is inserted into the slot, the sleeve edge fits the inner wall of the top opening, thereby improving the connection strength.

[0082] In some embodiments, in some electronic device shells 10 adopting the detachable structure of the top panel 210 and the bottom panel 220, the top opening 14 and the bottom opening 15 are formed by the butt joint of two parts. For example, the front side plate 232 of the front half shell 230 and the rear side plate 242 of the rear half shell 240 are butt jointed, and the left side plate 312 of the left half shell 310 and the right side plate 322 of the right half shell 320 are butt jointed. These parts are connected in a detachable manner at the butt joint, such as one or more of threaded connection (see FIGS. 4-6), buckle connection structure (see FIG. 8), fastener connection, mortise and tenon connection structure, and nested connection structure.

[0083] In some embodiments, as shown in FIG. 8, the front half shell and the rear half shell are provided with a detachable connection structure at the butt joint, including a buckle arranged on one of the front side plate 232 and the rear side plate 242, and a buckle groove arranged 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 through the cooperation of the buckle and the buckle groove.

[0084] In some embodiments, as shown in FIG. 1 and FIG. 8, the mounting portion 11 comprises a mounting slot extending to both sides of the housing 10 and penetrating the two sides of the housing 10, the length of the mounting slot is the width of the back of the housing, and the length of the mounting slot is less than the length of the wiring port. That is, the mounting slot extends along the left and right directions of the back of the electronic device housing 10 and penetrates the left and right sides of the housing 10, so that when mounted on the guide rail of the control cabinet, the guide rail passes through the mounting slot to achieve fixation. Specifically, the mounting slot can adopt a dovetail slot, or a similar structure with a narrower slot opening than a slot bottom, so that the guide rail does not come off after passing through the mounting slot transversely.

[0085] In some embodiments, the electronic device housing 10 is assembled by multiple components, for example, as shown in FIG. 1, the mounting slot is arranged between the first housing 110 and the second housing 120, and one slot wall of the mounting slot is the plane where the butt joint is located.

[0086] Similarly, in some embodiments, as shown in FIG. 1, the first housing 110 and the second housing 120 also adopt a similar detachable connection mode at the butt joint, for example, one or more of a threaded connection structure, a buckle connection structure, a fastener connection, a mortise and tenon connection structure, and a nested connection structure.

[0087] Specifically, as shown in FIG. 1, the detachable connection structure comprises a threaded hole arranged on one of the first housing 110 and the second housing 120, and a threaded fastener (not shown) for fixing the first housing 110 and the second housing 120.

Two wiring ports 12 are arranged on the two sheet metal pieces forming the top panel and the bottom panel, respectively, and are formed by punching and cutting. Among them, the other two sheet metal pieces form two connected panels of the housing by bending, specifically, one sheet metal piece is bent by 90 degrees to form the front panel and the left panel, and the other sheet metal piece is bent by 90 degrees to form the rear panel and the right panel. Among them, the sheet metal piece forming the rear panel is provided with a mounting fastening hole or an L-shaped hanging hole, and the length of the screw head protruding from the guide rail, the hanging hole is used to fix the housing on the screw head of the guide rail.

[0090] For example, in FIGS. 9b-9e, a scheme in which the shell is formed by two sheet metal pieces is shown, each of which can form two or three adjacent panels of the shell, which can be flexibly set according to actual needs, and the total number of panels formed by the two sheet metal pieces is still six, which remains unchanged. The two sheet metal pieces are provided with a folded edge at the connection, and the folded edge is fastened and connected with the edge of the panel by being overlapped with the edge and being provided with a threaded screw and / or a nested abutment.

[0091] The top panel and the bottom panel of the shell can be formed on the same sheet metal piece or on two sheet metal pieces, that is, when the top panel and the bottom panel of the shell are formed on the same sheet metal piece, the sheet metal piece is provided with a wiring port 12 formed by a hole at a position corresponding to the top panel and the bottom panel, respectively; when the top panel and the bottom panel of the shell are formed on two sheet metal pieces, the two sheet metal pieces are provided with a wiring port 12 formed by a hole at a position corresponding to the top panel and the bottom panel, respectively.

[0092] In some embodiments, the mounting portion 11 can be an L-shaped punched hole on the back of the shell (i.e., on the rear panel) that can be matched with a connecting piece on the guide rail; can be a threaded hole or a fastening hole for mounting the guide rail base; can also be a gap (slit), notch, protrusion, etc. that surrounds the back (the periphery of the rear panel) and can be matched with a mounting floor clamp for fixation, such as a joint gap or protrusion formed on the periphery of the back after the sheet metal pieces are spliced.

[0093] At the same time, the electronic device provided in the embodiments shown in FIGS. 10 and 11 includes a circuit board 20 and the shell 10 of the electronic device provided in the above embodiments, 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 the side close to the wiring port 12, and the ports of the wiring terminals 30 are exposed in the wiring port 12.
