The bolts 520 are disposed through the holder body 510. The nuts 530 are tightened on the bolts 520 so as to fix the bolt 520 on the holder body 510.

The fixed holder 300 and the adjustable holders 400 and 500 may have similar features to be connected to the base plates 100, but the holes that they cooperate with decide their position on the base plate 100. Specifically, the fixed holder 300 is fixed with the first positioning holes 111 and the first insertion holes 112, the adjustable holder 400 can be fixed to one of the pairs of the second positioning holes 121 and one of the groups of the second insertion holes 122 so as to be positioned at the desired place, and the adjustable holder 500 is fixed to one of the pairs of the third positioning holes 131 and one of the groups of the third insertion holes 132 so as to be positioned at the desired place. Note that the configuration enables the position adjustment of the adjustable holders 400 and 500 may be similar, thus the following paragraphs merely describe the connection between the adjustable holder 500 and the base plate 100.

Referring to FIG. 3, FIG. 3 is a partial exploded view of the adjustable fixing assembly 10 in FIG. 2. The holder body 510 of the adjustable holder 500 includes a pair of positioning pillars 511 configured to be inserted into one of the pairs of third positioning holes 131.

As shown in FIG. 2, the cover plate 600 includes a plate portion 610 and a protrusion portion 620 protruding from the plate portion 610. The protrusion portion 620 of the cover plate 600 is formed by a stamping (also known as pressing) process. In this embodiment, the plate portion 610 includes a plurality of through holes 611. The plate portion 610 of the cover plate 600 can be placed on the fixed holder 300 and the adjustable holders 400 and 500. Screws 830 are respectively disposed through some of the through holes 611 corresponding to screw holes of the fixed holder 300 and the adjustable holders 400 and 500 and are screwed into the screw holes on the fixed holder 300 and the adjustable holders 400 and 500.

There are two ways to install the cover plate 600 with respect to the base plate 100, one is shown in FIG. 5 (first installation position), and the other is shown in FIG. 7 (second installation position).

In this embodiment, the plate portion 610 includes a plurality of first screw holes 612, and the protrusion portion 620 includes a plurality of second screw holes 621. The fasteners 700 can be fixed to the first screw holes 612 of the plate portion 610 or the second screw holes 621 of the protrusion portion 620 depending on the position of the cover plate 600, wherein the selection of the position of the cover plate 600 may be decided based on the size of the electrical device. Also, to adapt to different sizes of electrical device, the positions of the adjustable holders 400 and 500 may also be changed accordingly.

In specific, referring to FIGS. 4 to 5, FIG. 4 is a perspective view of the adjustable fixing assembly 10 in FIG. 1 when a large-sized transformer 20 is accommodated on the adjustable fixing assembly 10, FIG. 5 is a cross-sectional view of the adjustable fixing assembly 10 in FIG. 4.

Firstly, as shown in FIGS. 4 and 5, to accommodate a large-sized transformer 20, the cover plate 600 can be installed in the first installation position to spare a larger accommodation space between the cover plate 600 and the base plate 100 for the transformer 20. As such, the protrusion portion 620 is located opposite to the transformer 20 and does not interfere with the transformer 20. As shown, the transformer 20 has a height H1 which is close to but still smaller than the minimum distance D1 between the plate portion 610 of the cover plate 600 and the base plate 100. In addition, the fastener 700 can be rotated (e.g., along a direction A) to move a first distance L1 to contact a surface of the transformer 20 facing towards the cover plate 600. By doing so, although the transformer 20 may not in direct contact with the cover plate 600 in the first installation position, the fastener 700 can limit the movement of the transformer 20 towards or away from the cover plate 600. As shown, the movement of the transformer 20 in the Z-axis is limited.

Also, the adjustable holders 400 and 500 can be moved to hold the transformer 20. Take the operation of the adjustable holder 400 as an example, as shown, the holder body 410 of the adjustable holder 400 and/or the bolts 420 can be moved towards the transformer 20 along a direction B so as to make the distance between the adjustable holder 400 and the fixed holder 300 fit with the width W1 of the transformer 20. Specifically, the holder body 410 can be fixed to the desired second positioning holes 121 and the desired second insertion holes 122 to move the bolts 420 to the transformer 20 as close as possible, and the adjustments of the bolts 420 can eliminate the possible gap between the bolts 420 and the transformer 20. By doing so, the bolts 420 can press against the transformer 20, such that the transformer 20 can be clamped by the adjustable holder 400 and the fixed holder 300. As such, the transformer 20 is unable to move with respect to the fixed holder 300 and the adjustable holder 400. As shown, the movement of the transformer 20 in the X-axis is limited. Note that the 420 may contact the transformer 20 by merely switching the position of the holder body 410.

Similarly, the movement of the transformer 20 in the Y-axis can be limited by the cooperation of the adjustable holder 500 and the fixed holder 200, thus the same or similar descriptions will not be repeated.

On the other hand, the adjustable fixing assembly 10 is also capable of accommodating a small-sizes transformer. Please see FIGS. 6-7, to accommodate a small-sizes transformer 30, the cover plate 600 can be switched to the second installation position. By doing so, the accommodation space between the cover plate 600 and the base plate 100 becomes relatively small so that the available room is closer to the size of the transformer 30, and the adjustment of the fasteners 700 can eliminate the possible gap between the 620 and the transformer 30. As shown, the transformer 20 has a height H2 which is close to but still smaller than the minimum distance D3 between the protrusion portion 620 and the base plate 100, and the fasteners 700 can be rotated (e.g., along a direction A) to move a first distance L2 to contact a surface of the transformer 30 facing towards the 620, where the minimum distance D3 is substantially equivalent to the minimum distance D1 minus the height D2 of the protrusion portion 620 that is, after the cover plate 600 is the second installation position, the fasteners 700 can be moved to adjust the distance between the fasteners 700 and the base plate 100 to mate with the height H2 of the transformer 30, thereby limiting the movement of the transformer 20 in the Z-axis.

In this embodiment, since the cover plate 600 has the protrusion portion 620, such that the size of the available space between the cover plate 600 and the base plate 100 for an electrical device can be changed according to the size of the electrical device. As such, the adjustable fixing assembly 10 is suitable for accommodating different sizes of electrical devices.

In addition, the protrusion portion 620 of the cover plate 600 can define a room to be closer to the size of the electrical device to be accommodated in the adjustable fixing assembly 10, which may largely reduce the required adjustment distance of the fasteners 700, thereby reducing the time spent on adjusting the fasteners 700.

Specifically, as shown in FIGS. 6 and 7, for achieving to contact the transformers 30, the fasteners 700 are only required to be moved the second distance L2; however, if the fasteners 700 are mounted to the first screw holes 612 of the plate portion 610, the fasteners 700 are required to be moved a distance substantially equivalent to the second distance L2 plus the height D2 of the protrusion portion 620. Therefore, it is understood that the protrusion portion 620 of the cover plate 600 helps to shorten the adjustment distance of the fasteners 700 for contacting the transformer 30 as the cover plate 600 is in the second installation position and thus saving the time spending on adjusting the fasteners 700.

The positions of the adjustable holders 400 and 500 can be moved to hold the transformer 30. Take the operation of the adjustable holder 400 as an example, as shown, the holder body 410 of the adjustable holder 400 and/or the bolts 420 can be moved towards the transformer 30 along a direction B so as to make the distance between the adjustable holder 400 and the fixed holder 300 fit with the width W2 of the transformer 30. Specifically, the holder body 410 can be fixed to the desired second positioning holes 121 and the desired second insertion holes 122 to move the bolts 420 to the transformer 30 as close as possible, and the adjustments of the bolts 420 can eliminate the possible gap between the bolts 420 and the transformer 30. By doing so, the bolts 420 can press against the transformer 30, such that the transformer 30 can be clamped by the adjustable holder 400 and the fixed holder 300. As such, the transformer 30 is unable to move with respect to the fixed holder 300 and the adjustable holder 400. As shown, the movement of the transformer 30 in the X-axis is limited. Note that the bolts 420 may contact the transformer 30 by merely switching the position of the holder body 410.

Similarly, the movement of the transformer 30 in the Y-axis can be limited by the cooperation of the adjustable holder 500 and the fixed holder 200, and thus the same or similar descriptions will not be repeated.

In this embodiment, the adjustable fixing assembly 10 simultaneously includes the protrusion portion 620 of the cover plate 600 and the adjustable holders 400 and 500, but the present disclosure is not limited thereto; in some other embodiments, the adjustable fixing assembly may not include the adjustable holders 400 and 500, or may not include the protrusion portion 620 of the cover plate 600 and the adjustable holder 500. In addition, the adjustable fixing assembly 10 includes the fixed holders 200 and 300 and the adjustable holders 400 and 500, but the present disclosure is not limited thereto; in some other embodiments, all of the holders of the adjustable fixing assembly may be adjustable.

According to the adjustable fixing assemblies as discussed above, since the cover plate has the protrusion portion, such that the size of the available space between the cover plate and the base plate for an electrical device can be changed according to the size of the electrical device. As such, the adjustable fixing assembly is suitable for accommodating different sizes of electrical devices.

In addition, the protrusion portion of the cover plate can define a room to be closer to the size of the electrical device to be accommodated in the adjustable fixing assembly, which may largely reduce the required adjustment distance of the fasteners, thereby reducing the time spent on adjusting the fasteners.

Furthermore, the positioning pillars allows the adjustable holder to be firstly positioned at a position closest to the electrical device, and then the bolts can be moved with respect to the holder body of the adjustable holder to contact the electrical device, such that the adjustment distance of the bolts can be shortened and thus saving the time spending on adjusting the bolt.
