Description

Technical Field

[0001] The present application belongs to the technical field of power supply equipment, and in particular, relates to a guide rail power supply. Background Art

[0002] DIN rail power supply is widely used in industrial control equipment, home control system, building or factory automation industrial control system, electromechanical equipment, rail transportation and other industrial power supply equipment in harsh environments. DIN rail power supply has the advantages of high cost performance, high efficiency and energy saving, standard DIN rail installation, compact structure, high stability, strong anti-interference ability, etc., so it is widely used in power supply equipment in the above fields.

[0003] The DIN-rail power supplies on the market are generally equipped with one or more main control boards, which are equipped with a variety of electrical components. These electrical components are highly concentrated and generate a lot of heat, which can easily affect the normal operation of the DIN-rail power supply. Therefore, the DIN-rail power supply is generally equipped with a heat dissipation structure. In addition to setting heat dissipation holes on the outer shell and / or installing a cooling fan inside, the heat dissipation structure on the common DIN-rail power supply also specifically sets a heat conductor between the main control board and the outer shell. One end of these heat conductors is connected to the main control board, and the other end extends to the outer shell of the DIN-rail power supply. The heat on the main control board is quickly transferred to the outer shell by the heat conductor to ensure the heat dissipation effect.

[0004] However, since the guide rail power supply has a variety of specifications, the outer shell sizes of guide rail power supplies of different specifications are different. The different sizes of outer shells result in differences in the distance between the outer shell and the main control board, resulting in the need for the heat conductor to be adjusted for the internal space of guide rail power supplies of different specifications. The solution adopted in the prior art is to obtain the heat conducting plate of the corresponding size by cutting. Before cutting, it is necessary to measure the distance between the main control board and the outer shell, and then cut the heat conducting member. After obtaining the heat conducting member of the corresponding length, it can be installed between the main control board and the outer shell. Due to the high accuracy requirements, if there are differences in the measured dimensions or the cutting is inaccurate, the two ends of the heat conducting member will not be able to stably contact the main control board and the outer shell. If the contact is poor, the heat dissipation effect will be affected, so the measurement and cutting of the heat conducting member are required to be high, and the product yield is low.

[0005] It can be seen that the heat dissipation structure on the guide rail power supply in the prior art still has many defects, which is a technical problem that the power supply equipment manufacturers urgently need to solve. Summary of the invention

[0006] The purpose of the embodiments of the present application is to provide a guide rail power supply to solve the technical problem that the heat conductive parts used in the guide rail power supply of the prior art are difficult to adapt to the internal installation of guide rail power supplies of different specifications, resulting in the heat conductive parts being unable to play a heat conductive role, thereby affecting the heat dissipation effect of the guide rail power supply.

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] The heat dissipation structure on the traditional guide rail power supply, in addition to setting heat dissipation holes on the casing and / or installing a cooling fan inside, also specially sets a heat conductor between the main control board and the casing. One end of the heat conductor is connected to the main control board, and the other end extends to the casing of the guide rail power supply. The heat on the main control board is quickly transferred to the casing by the heat conductor to ensure the heat dissipation effect.

[0044] However, since the guide rail power supply has a variety of specifications, the outer shell sizes of guide rail power supplies of different specifications are different. The different sizes of outer shells result in differences in the distance between the outer shell and the main control board, resulting in the need for the heat conductor to be adjusted for the internal space of guide rail power supplies of different specifications. In the related art, the solution considered is that since the heat conductor mainly adopts a plate structure, the heat conductor plate of the corresponding size can be obtained by cutting. In the actual assembly process, it is necessary to first measure the distance between the main control board and the outer shell, and then cut the heat conductor to obtain the heat conductor of the corresponding length before installing it between the main control board and the outer shell.

[0045] It can be seen that the entire adjustment operation is complicated and cumbersome, which increases the production process and processing costs; moreover, due to the high accuracy requirements, if there are differences in the measured dimensions or inaccurate cutting, both ends of the heat conductor will not be able to stably contact the main control board and the shell. If the contact is poor, the heat dissipation effect will be affected. Therefore, the above-mentioned measurement and cutting of the heat conductor have high requirements, and the product yield is low.

[0046] Here, an embodiment of the present application provides a new type of guide rail power supply, which improves the heat dissipation structure inside the guide rail power supply, so that the heat conductive part arranged between the main control board and the outer shell can adjust the telescopic length, so as to adapt to the distance between the main control board and the outer shell inside the guide rail power supply of different specifications, and effectively solves the technical problem that the heat conductive part used in the traditional guide rail power supply is difficult to adapt to the internal installation of the guide rail power supply of different specifications, resulting in the heat conductive part being unable to play a heat conducting role, affecting the heat dissipation effect of the guide rail power supply. It is now described in detail.

[0047] Please also read Figure 1 , Figure 2 and Figure 3 The guide rail power supply includes a housing 1, a main control board 2 and a heat conducting component 100.

[0048] The housing 1 can be configured according to the requirements of the production and installation scenarios, and the housing 1 can be assembled from a plurality of panels to form a box structure. Figure 2 and Figure 3As shown, the housing 1 of the guide rail power supply is a rectangular box structure, including a C-shaped frame 11 and four side panels, and corresponding electrical components, such as the main control board 2 and other electrical components of the present application, can be installed in the C-shaped frame 11. Therefore, the connection object between the main control board 2 and the housing 1 in the embodiment of the present application is mainly the C-shaped frame 11, and the heat conduction component of the present application is used to be arranged between the main control board 2 and the C-shaped frame 11 of the housing 1, so that the heat on the main control board 2 is transferred to the C-shaped frame 11 for rapid heat dissipation.

[0049] The four side panels are assembled on the C-shaped frame 11 from four directions. One or more of the four side panels can be provided with heat dissipation holes or heat dissipation nets connecting the inside and outside of the guide rail power supply. The remaining panels can be provided with a control panel or a guide rail fixing mechanism, so that the guide rail power supply can be installed on the guide rail of the application scenario.

[0050] Please also read Figure 3 and Figure 4 , the main control board 2 is accommodated in the housing 1, and there is an isolation space between the main control board 2 and the inner wall of the housing 1. In the embodiment of the present application, the isolation space mainly refers to the space between the C-shaped frame 11 in the above-mentioned housing 1 assembly and the main control board 2. The isolation space can be used to install other electrical components, heat dissipation components such as a heat dissipation fan or the heat conduction assembly 100 of the present application, etc.

[0051] The heat conducting component 100 is used to be arranged between the housing 1 and the main control board 2, and can be specifically arranged in the isolation space between the main control board 2 and the inner wall of the housing 1. The heat conducting component 100 includes a fixing plate 3 and an adjusting plate 4, and the fixing plate 3 is used to be fixed on the housing 1. The adjusting plate 4 is used to abut against the main control board 2, so that the heat generated by the main control board 2 when working is transferred to the housing 1 through the heat conducting component 100. The adjusting plate 4 can also be used to install electrical components connected to the main control board 2, and the heat generated by these electrical components when working can be directly transferred to the housing 1 through the heat conducting component 100.

[0052] Among them, the adjustment plate 4 is connected to the fixed plate 3, and an adjustable mechanism 200 is provided at the connecting portion between the fixed plate 3 and the adjustment plate 4. The adjustable mechanism 200 is used to adjust the telescopic length of the adjustment plate 4 from the fixed plate 3 to the main control board 2, so as to change the extension range of the adjustment plate 4 and the fixed plate 3, so as to adapt to the spacing distance between the main control board 2 and the outer casing 1 inside the guide rail power supply of different specifications.

[0053] Compared with the prior art, the guide rail power supply provided by the embodiment of the present application has a difference in the distance between the main control board 2 and the outer shell 1 for guide rail power supplies of different specifications, resulting in the problem that the heat conductive parts installed between the main control board 2 and the outer shell 1 cannot be adapted. The present application improves the structure of the heat conductive component 100 arranged inside the guide rail power supply. The heat conductive component 100 includes a fixed plate 3 and an adjustment plate 4 connected to each other. The fixed plate 3 is fixed on the outer shell 1. An adjustable mechanism 200 is provided on the connection part between the adjustment plate 4 and the fixed plate 3. The adjustable mechanism 200 is used to adjust the telescopic length of the adjustment plate 4 from the fixed plate 3 to the main control board 2, so that the extension length of the entire fixed plate 3 and the adjustment plate 4 can adapt to the distance between the main control board 2 and the outer shell 1 inside the guide rail power supplies of different specifications. The two ends of the heat conductive component 100 can be stably contacted or connected with the main control board 2 and the outer shell 1 respectively, and the heat conductive effect can be stably exerted. There is no need to perform measurement and cutting adjustment operations, which improves the yield rate and effectively ensures that the heat generated by the main control board 2 during operation can be quickly transferred to the housing 1, thereby improving the heat dissipation effect of the guide rail power supply.

[0054] For the structure of the adjustable mechanism 200, in one embodiment of the present application, please refer to Figure 5 The adjustable mechanism 200 includes a first elongated hole 31 formed on the fixing plate 3 and a second elongated hole 41 formed on the adjusting plate 4. The first elongated hole 31 and the second elongated hole 41 are aligned with each other in their length direction and have corresponding positions so as to allow fasteners such as screws and nuts to be inserted and fixed.

[0055] Thus, by utilizing the hole-slot structure of the first elongated hole 31 and the second elongated hole 41, the fastener can be adjusted and fixed within the hole-slot overlap range of the first elongated hole 31 and the second elongated hole 41, thereby adjusting the telescopic length of the fixing plate 3 and the adjusting plate 4. It can be seen that the entire adjustable mechanism 200 has a simple structure, is easy to implement, and is convenient for installation and adjustment.

[0056] Preferably, the fixing plate 3 may be provided with a plurality of first elongated holes 31, the number of second elongated holes 41 on the adjusting plate 4 is the same as that of the first elongated holes 31, and the positions of the plurality of first elongated holes 31 and the plurality of second elongated holes 41 correspond one to one. On the one hand, by increasing the number of elongated holes, the connection points between the fixing plate 3 and the adjusting plate 4 are increased, thereby improving the connection strength and connection stability. On the other hand, the increased elongated holes can form heat dissipation holes or heat dissipation grids, which is conducive to improving the heat dissipation effect.

[0057] Regarding the structure of the adjustable mechanism 200, in another embodiment of the present application (not shown), the adjustable mechanism 200 includes a rack portion arranged on the fixed plate 3 and an active buckle arranged on the adjustment plate 4. The active buckle can preferably adopt a quick clamping structure similar to that which can be pulled open or pressed together by hand.

[0058] The rack part is arranged at the connection part between the fixed plate 3 and the adjustment plate 4, and the teeth on the rack part are arranged along the length direction of the fixed plate 3. The movable buckle on the adjustment plate 4 can be buckled with the teeth on the rack part, and the movable buckle can be selectively buckled on the teeth at the corresponding part, which is similar to the "adjustment buckle structure on the belt". In this way, the telescopic length of the fixed plate 3 and the adjustment plate 4 can also be adjusted.

[0059] For the specific structure of the adjustment plate 4, in one embodiment of the present application, please refer to Figure 4 and Figure 5 A detachable block 42 is provided on one side of the adjustment plate 4 for contacting the main control board 2. The detachable block 42 can be easily removed to form an avoidance gap 43 on the plate surface of the adjustment plate 4. The avoidance gap 43 on the adjustment plate 4 can be used to avoid electrical components provided on the main control board 2, so that the edge of the adjustment plate 4 outside the avoidance gap 43 can contact the main control board 2, effectively ensuring the heat conduction effect.

[0060] In this embodiment, if Figure 5 As shown, there are multiple detachable blocks 42 arranged in a matrix on the adjustment board 4, and adjacent detachable blocks 42 are connected together by connecting ribs. When removal is required, the connecting ribs can be directly broken to separate the detachable blocks 42 and remove them from the adjustment board 4. In actual use, one or more detachable blocks 42 can be removed from the adjustment board 4 according to the volume of the electrical components corresponding to the position on the main control board 2, thereby forming a suitable size of the avoidance gap 43, which effectively improves the installation adaptability of the adjustment board 4.

[0061] In practical applications, multiple heat-conducting components 100 can be arranged inside the guide rail power supply, and adjacent heat-conducting components 100 are arranged at intervals to play a separation role, so that electrical components with high and low voltage circuits can be isolated. Under the premise of ensuring the spacing distance of the above-mentioned high and low voltage circuits, the layout of each heat-conducting component 100 inside the guide rail power supply can be designed to meet the heat dissipation requirements of the electrical components installed inside the guide rail power supply.

[0062] It can be seen that for the structure of the adjustment plate 4, in another embodiment of the present application, please refer to Figure 6 The adjustment plate 4 includes a first sub-plate 44 and a second sub-plate 45 connected to each other. The second elongated hole 41 is provided on at least one end of the first sub-plate 44 and is used to be connected to the fixing plate 3 .

[0063] The surfaces of the first sub-board 44 and the second sub-board 45 can be used to install electrical components connected to the main control board 2, or the other ends of the first sub-board 44 and the second sub-board 45 can be used to abut against the main control board 2 to ensure the heat conduction effect.

[0064] The second sub-plate 45 extends outward from the plate surface of the first sub-plate 44. Figure 6 As shown, the second sub-plate 45 can extend outward from one end of the first sub-plate 44, so that the adjustment plate 4 forms an L-shaped plate. In other embodiments (not shown), the second sub-plate 45 can also extend outward from the plate surface of the first sub-plate 44, so that the adjustment plate 4 forms a T-shaped plate.

[0065] Therefore, under the premise of ensuring the spacing distance of the high and low voltage circuits, the specific shape of the adjustment board 4 is designed accordingly. The adjustment board 4 includes a first sub-board 44 and a second sub-board 45, and the second sub-board 45 can extend outward on the first sub-board 44 to increase the installable or contactable parts on the adjustment board 4, effectively meeting the installation and heat dissipation requirements of the electrical components.

[0066] For the specific structure of the fixing plate 3, in one embodiment of the present application, please refer to Figure 7 The fixed plate 3 includes a third sub-plate 32 and a fourth sub-plate 33 . The extension directions of the third sub-plate 32 and the fourth sub-plate 33 are perpendicular. The third sub-plate 32 is provided with the first long strip hole 31 and is used to connect with the adjustment plate 4 .

[0067] The fourth sub-board 33 is bent from the end of the third sub-board 32 and extends outwardly. The board surface of the fourth sub-board 33 is used for being fixedly connected to the housing 1 .

[0068] Therefore, compared with the method of directly connecting the end of the fixing plate 3 with the outer shell 1, the present application sets a connection structure with the outer shell 1 on the board surface of the fourth sub-board 33, and utilizes the board surface of the fourth sub-board 33 to be fixedly connected with the outer shell 1, thereby effectively increasing the connection area between the fixing plate 3 and the outer shell 1, thereby improving the fixing effect of the fixing plate 3 and the outer shell 1.

[0069] In addition, since the extension directions of the third sub-board 32 and the fourth sub-board 33 are perpendicular, after the fourth sub-board 33 is fixedly connected to the outer shell 1, the verticality of the third sub-board 32 to the main control board 2 can be ensured, so that at least a portion of the fixed plate 3 can extend vertically in the direction of the main control board 2, which is convenient for connection and cooperation with the adjustment plate 4.

[0070] In practical applications, the two ends of the heat-conducting component 100 are in contact with the main control board 2 and the housing 1 respectively, and the adjustment plate 4 and the fixing plate 3 in the heat-conducting component 100, as well as the housing 1, are all made of metal plates to ensure structural strength. However, since metal parts are easy to conduct electricity, the main control board 2, the heat-conducting component 100 and the housing 1 are easy to form an in-and-out conductive bridge, which can cause the external voltage to directly enter the main control board 2, or the internal voltage to be transmitted to the housing 1, which can easily cause leakage or short circuit.

[0071] Here, in one embodiment of the present application, please refer to Figure 7 and Figure 8 The fourth sub-board 33 is also provided with an insulating sheet 5, the area of ​​which is not less than the surface area of ​​the fourth sub-board 33. The insulating sheet 5 is disposed between the surface of the fourth sub-board 33 and the inner wall of the housing 1 to provide isolation and insulation.

[0072] For the fixing structure between the fourth sub-board 33, the insulating sheet 5 and the housing 1, in one embodiment of the present application, please refer to Figure 7 and Figure 8 The outer shell 1 is provided with a third long hole 12 and a mounting screw 13, the fourth sub-board 33 is provided with a mounting hole 331, and the insulating sheet 5 is provided with a through hole 51. The mounting screw 13 sequentially penetrates the third long hole 12 on the outer shell 1, the through hole 51 on the insulating sheet 5 and the mounting hole 331 on the fourth sub-board 33, so that the fourth sub-board 33, the insulating sheet 5 and the outer shell 1 are closely fitted together, and at the same time, the insulating sheet 5 is clamped between the fourth sub-board 33 and the outer shell 1, which plays a good insulating role.

[0073] Since the mounting screw 13 is also a metal part, it is driven into the insulating sheet 5 and the fourth sub-board 33 from the housing 1 in sequence, so it also forms a conductive bridge structure. Figure 7 An insulating ring 131 is also sleeved on the mounting screw 13 , and the insulating ring 131 is used to block between the screw head of the mounting screw 13 and the housing 1 , and the insulating ring 131 plays an insulating role between the mounting screw 13 and the housing 1 .

[0074] For the structure of the main control board 2 in the guide rail power supply of the present application, in one embodiment of the present application, please refer to Fig. 9 The main control board 2 includes a first main board 21 and a second main board 22. The first main board 21 and the second main board 22 are arranged in the housing 1 with their surfaces facing each other. The heat conduction component 100 of the present application can be installed between the front of each main board and the housing 1.

[0075] A partition column 23 is provided between the back of the first main board 21 and the back of the second main board 22 . The partition column 23 can be provided at the four corners of the two main boards to improve the supporting effect and form an isolation cavity 24 between the first main board 21 and the second main board 22 .

[0076] It can be seen that the two main boards are arranged back to back, and an isolation cavity 24 is formed between the backs of the two main boards.
