Description

Technical Field

[0001] This utility model relates to the field of power distribution technology, and in particular to a mounting bracket structure and power distribution system. Background Technology

[0002] A fuse is an electrical device that breaks the circuit by melting a fusible element due to the heat generated when the current exceeds a specified value for a certain period of time. It is widely used in high and low voltage power distribution systems, control systems, and electrical equipment as a protector against short circuits and overcurrents.

[0003] In the existing technology, electrical components such as fuses and shunts are generally mounted on specific mounting brackets. These mounting brackets are usually designed separately according to the size requirements of different electrical components. A single mounting bracket can only accommodate electrical components of a certain size, resulting in poor versatility and high replacement costs. Utility Model Content

[0004] The purpose of this utility model is to provide a mounting bracket structure and power distribution system that can adapt to the installation of electrical components of different sizes, improve installation versatility, and reduce replacement costs.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The mounting bracket structure includes a mounting base, at least two mounting seats, and at least two fixing studs. The fixing studs are detachably mounted on the mounting seats in a one-to-one correspondence. At least one of the mounting seats is a sliding seat, which is slidably mounted on the mounting base to adjust the distance between the at least two mounting seats.

[0007] In some embodiments, the mounting base has a mounting groove, the opposite wall of the mounting groove has a sliding groove, and the sliding seat has a sliding boss that slides within the sliding groove.

[0008] In some embodiments, the sliding boss can disengage from the groove under the action of an external force.

[0009] In some embodiments, the sliding seat is provided with two spaced-apart support plates. The first end of the support plate is connected to the sliding seat, and the second end of the support plate extends outward from the sliding seat. The sliding boss is provided at the second end of the support plate. The second ends of the two support plates can approach each other under the action of external force and tend to maintain the distance when the external force is removed.

[0010] In some embodiments, each mounting base is provided with a limiting groove, the opening of which is located on the side of the mounting base away from the mounting base; one of the groove walls of the limiting groove has an opening, and a limiting protrusion is provided on the groove wall adjacent to the opening, forming a clamping space between the limiting protrusion and the bottom wall of the limiting groove; each fixing stud includes a stud body and a stud seat, the stud body is disposed on the stud seat, and the stud seat is clamped in the clamping space by the opening.

[0011] In some embodiments, the mounting base is provided with a limiting member that prevents the stud seat from disengaging from the clamping space through the opening.

[0012] In some embodiments, the bottom wall of the limiting groove is provided with a hollow notch, the hollow notch extends along the direction in which the stud seat enters and exits the limiting groove, the limiting member includes a limiting strip, the end of the limiting strip away from the opening is connected to the bottom of the side wall of the limiting groove, the end of the limiting strip near the opening is suspended and is provided with a blocking protrusion, the blocking protrusion having a tendency to protrude into the bottom wall of the limiting groove.

[0013] In some embodiments, a guide surface is provided on the side of the blocking protrusion away from the closed end of the limiting groove, and the guide surface is inclined from the top end to the bottom end of the blocking protrusion toward the end away from the side wall of the limiting groove connected to the limiting strip.

[0014] In some embodiments, the stud further includes a fixing platform, which is disposed on the stud seat, and the stud body is disposed on the fixing platform. The outer dimensions of the fixing platform are smaller than the outer dimensions of the stud seat. When the stud seat is confined to the clamping space, the end face of the fixing platform protrudes beyond the end face of the limiting protrusion.

[0015] A power distribution system is also provided, which includes the above-described mounting bracket structure.

[0016] The beneficial effects of this utility model are:

[0017] When fixing electrical components, simply adjust the spacing of the fixing studs using the sliding base, then place the pins of the electrical component onto the fixing studs, and finally lock them in place using the locking mechanism. When installing electrical components of different sizes, adjust the distance between the fixing studs 2 using the sliding base to match the size of the different electrical components. Remove the fixing studs from the mounting base to replace them with the appropriate size for the new electrical component, then place the new component on top and lock it in place using the locking mechanism. This mounting bracket structure, on the one hand, absorbs assembly tolerances through the adjustable spacing of the fixing studs, making the fixing more stable; on the other hand, it improves the versatility of the installation, avoiding the need to frequently change the entire fixing structure when using different sizes—only individual fixing studs need to be replaced, thus reducing costs.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] like Figures 1 to 4 As shown, this application provides a mounting bracket structure, which includes a mounting base 1, at least two mounting seats and at least two fixing studs 2. The fixing studs 2 are detachably mounted on the mounting seats in a one-to-one correspondence. At least one mounting seat is a sliding seat 3, which is slidably mounted on the mounting base 1 to adjust the distance between the at least two mounting seats.

[0032] When fixing electrical components, simply adjust the spacing of the fixing studs 2 using the sliding base 3, then place the pins of the electrical component onto the fixing studs 2, and finally lock them in place using the locking mechanism. When installing electrical components of different sizes, adjust the distance between the fixing studs 2 using the sliding base 3 to match the size of the different electrical components. Remove the fixing studs 2 from the mounting base to replace them with the ones that match the different electrical components, then place the new electrical components on top and lock them in place using the locking mechanism. Thus, through the above-mentioned mounting bracket structure, on the one hand, the adjustable spacing of the fixing studs 2 absorbs assembly tolerances, making the fixing more stable; on the other hand, it also improves the versatility of the installation, avoiding the need to frequently replace the entire fixing structure when using different sizes. Only the individual fixing studs 2 need to be replaced, reducing costs.

[0033] It should be noted that the locking element can be, but is not limited to, a nut. Furthermore, the aforementioned mounting bracket structure can also be used to mount and secure other electrical components such as shunts and fuses. The number of mounting bases and fixing studs 2 can be determined based on the number of pins of the electrical component to be mounted.

[0034] Specifically, the mounting base 1 is provided with a mounting groove 11, and a sliding groove 12 is formed on the opposite wall of the mounting groove 11. The sliding seat 3 is provided with two opposing sliding bosses 31, which slide within the two sliding grooves 12. When adjusting the spacing of the fixing studs 2, it is only necessary to move the sliding bosses 31 within the sliding grooves 12. Furthermore, the sliding bosses 31 can detach from the sliding grooves 12 under external force, thereby allowing for the replacement of sliding seats 3 of different sizes according to different scenarios, expanding the scope of application. More specifically, the sliding seat 3 is provided with two spaced-apart support plates 4. The first end of the support plate 4 is connected to the sliding seat 3, and the second end of the support plate 4 protrudes away from the sliding seat 3. The sliding bosses 31 are located at the second end of the support plate 4. The second ends of the two support plates 4 can approach each other under external force and tend to maintain their distance when the external force is removed. Therefore, when disassembly is required, it is only necessary to press the support plate 4 to disengage the sliding bosses 31 from the sliding grooves 12. In this embodiment, for ease of pressing, the sliding seat 3 is a groove-shaped seat. The first end of the support plate 4 is connected to the bottom of the groove of the groove-shaped seat, and the second end extends outward from the groove. A pressing notch is provided on the groove wall of the groove-shaped seat, and the pressing notch is opposite to the support plate 4, so that the support plate 4 can be pressed easily from the outside of the sliding seat. In this embodiment, the support plate 4 extends out of the groove. When the sliding boss 31 on the support plate 4 slides in the sliding groove 12, the sliding seat 3 abuts against the opening of the mounting groove 11, forming bidirectional support, making the sliding seat more stable.

[0035] like Figures 2 to 4As shown, in some embodiments, a limiting groove 32 is provided on the mounting base. The opening of the limiting groove 32 is located on the side of the mounting base away from the mounting base 1, that is, the opening of the limiting groove 32 is opposite to the opening of the groove-shaped seat (the limiting groove 32 is provided on the outer side of the bottom of the groove-shaped seat). An opening is provided on one of the groove walls of the limiting groove 32. A limiting protrusion 33 is provided on the groove wall adjacent to the opening. The two limiting protrusions 33 are spaced apart and opposite to each other. The limiting protrusions 33 extend from one end of the opening to the closed end. A clamping space is formed between the limiting protrusions 33 and the bottom wall of the limiting groove 32. The fixing stud 2 includes a stud body 21 and a stud seat 22. The stud body 21 is provided on the stud seat 22. The stud body 21 is provided with threads so that the locking member can be tightened. The stud seat 22 can slide into the clamping space formed between the limiting protrusion 33 and the groove wall of the limiting groove 32 through the opening and be fixed.

[0036] In the current embodiment, the fixing stud 2 is made of metal, while the mounting base 1 and the mounting seat are made of plastic to save costs. Since the mounting base 1 and the mounting seat are made of plastic, the fuse and the shunt will generate heat when they are working. When the heat is transferred to the mounting base 1 and the mounting seat, it will cause the mounting base 1 and the mounting seat to deform due to heat. In order to avoid the torque attenuation phenomenon of the locking member when the mounting base 1 and the mounting seat deform, the fixing stud 2 also includes a fixing platform 23. The fixing platform 23 is disposed on the stud seat 22, and the stud body 21 is disposed on the fixing platform 23. The outer dimension of the fixing platform 23 is smaller than the outer dimension of the stud seat 22. When the stud seat 22 is confined in the clamping space, the end face of the fixing platform 23 protrudes from the end face of the limiting protrusion 33. That is, when the locking member is locked, the locking member abuts against the end face of the fixing platform 23 and does not contact the limiting protrusion 33. Even if the mounting base 1 and the mounting seat deform, there will be no torque attenuation phenomenon.

[0037] In some embodiments, the stud seat 22 is rectangular, thereby preventing the stud body 21 from rotating when the locking member is tightened for fixation, thus playing an anti-rotation role. In other embodiments, the stud seat 22 may also be hexagonal or octagonal, etc.

[0038] In some embodiments, a limiting member 34 is provided on the mounting base. The limiting member 34 can unidirectionally prevent the stud seat 22 from disengaging from the opening and clamping space, ensuring the stability of the fixed stud 2. Specifically, the bottom wall of the limiting groove 32 is provided with a hollow notch 35, which extends along the direction in which the stud seat 22 enters and exits the limiting groove 32. The limiting member 34 includes a limiting strip 341. The end of the limiting strip 341 away from the opening is connected to the bottom of the side wall of the limiting groove 32, while the end of the limiting strip 341 near the opening is suspended to form a cantilever end. The cantilever end is provided with a blocking protrusion 342, which protrudes into the bottom wall of the limiting groove 32. The trend is such that when the stud seat 22 moves from the opening into the clamping space, the stud seat 22 abuts against the limiting protrusion 33, allowing the stud seat 22 to enter the clamping space. When the stud seat 22 disengages from the blocking protrusion 342, the blocking protrusion 342 returns to its tendency to protrude from the bottom wall of the limiting groove 32, thus confining the stud seat 22 within the clamping space. Without external force pressing the blocking protrusion 342, the fixing stud 2 cannot disengage, ensuring the stability of the fixing stud 2 installation. Furthermore, the above-mentioned sliding installation method also facilitates installation and subsequent disassembly and replacement for maintenance.

[0039] like Figure 3 As shown, in some embodiments, a guide surface 343 is provided on the side of the blocking protrusion 342 away from the closed end of the limiting groove 32. The guide surface 343 is inclined from the top end of the blocking protrusion 342 to the bottom end of the blocking protrusion 342 toward the end of the side wall of the limiting strip 341 that is connected to the limiting groove 32, so that the stud seat 22 can be more smoothly inserted into the limiting groove 32 when it is fixed.

[0040] like Figure 1 As shown, in some embodiments, in order to facilitate fixing the mounting base 1, the mounting base 1 is provided with a plurality of mounting holes 13, so as to fix it to the external component through the mounting holes 13.

[0041] This application also provides a power distribution system, which includes the aforementioned mounting bracket structure. The bracket structure is used to fix fuses, shunts, and other electrical components. The adjustable-pitch fixing studs 2 absorb assembly tolerances, making the fixing more stable. On the other hand, it also improves the versatility of installation, avoiding frequent replacement of the overall fixing structure under different size requirements. Only a single fixing stud 2 needs to be replaced, thus reducing costs.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
