[0026] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] After long-term research, the inventor found that if the length of the wire of the coil of the transformer is increased, the strength of the wire itself will decrease, and during transportation, the wire 11 may shake due to vibration, and there is a risk of wire breakage when the wire 11 shakes. In order to protect the wire 11 and reduce the risk of wire breakage, as Figures 1 to 3 shown, the transformer of the first embodiment includes: three coils 10 arranged at intervals, an iron core 20, clamping parts 30, insulators 40, and a first bracket 50. Among them, the three coils 10 are arranged on the iron core 20. The clamping parts 30 are clamped on the iron core 20. There are three insulators 40 arranged corresponding to the coils 10 one by one, and the wires 11 of each coil 10 are connected to the clamping parts 30 through the corresponding insulators 40. The middle parts of the wires 11 of each coil 10 are limited on the first bracket 50.

[0030] Applying the technical solution of this embodiment, the middle parts of the wires 11 of each coil 10 are limited on the first bracket 50, so that the shaking amplitude of the wires 11 is greatly reduced, thereby reducing the risk of wire breakage and playing a protective role for the wires 11.

[0031] It should be noted that in this embodiment, the "middle part of the wire 11" refers to other positions except the two ends of the wire 11. Preferably, the middle part of the wire 11 refers to the middle section in the vertical direction of the wire, and the length of the middle section accounts for half of the overall length of the vertical section of the wire.

[0032] As Figures 1 to 3 shown, in this embodiment, the wire 11 is limited on the first bracket 50 through a limiting member 60. The above structure is simple and easy to assemble. Of course, in other embodiments not shown in the figure, the wire 11 can also be limited on the first bracket 50 through a winding member (such as tape), and the above structure reduces the number of overall parts of the transformer and reduces the cost.

[0033] As Figures 1 to 3As shown, in this embodiment, when the wire 11 is fixedly arranged on the first bracket 50 through the limiting member 60, the limiting member 60 includes a limiting groove. The limiting groove faces the first bracket 50, and a wire threading channel 61 is formed between the limiting groove and the first bracket 50. The wire 11 is threaded through the wire threading channel 61. Specifically, during installation, first connect the wire 11 to the insulator 40, and then buckle the limiting member 60 at the middle position of the wire 11, so that the wire 11 is accommodated in the wire threading channel 61. Finally, fix the limiting member 60 on the first bracket 50. Specifically, the limiting member 60 and the first bracket 50 can limit the wire 11 in all directions in the horizontal plane, thereby greatly reducing the swaying amplitude of the wire 11, reducing the risk of wire breakage, and playing a protective role for the wire 11. Of course, in other embodiments not shown in the figure, the limiting member 60 can also be an elastic fastener. The elastic fastener has an inlet for the wire, and the wire 11 can be pressed into the elastic fastener through the inlet to play a limiting role.

[0034] Preferably, the limiting member 60 can be provided at one or more places according to actual needs to minimize the swaying amplitude of the wire 11.

[0035] For transformers of different models, the distance between two adjacent coils 10 is different. In order to make the same first bracket 50 adaptable to transformers of different models. In this embodiment, each limiting member 60 has multiple mounting positions on the first bracket 50, so that the mounting position of the limiting member 60 can be adjusted (adjusted left and right in the figure). The above structure makes the first bracket 50 and the limiting member 60 highly versatile. Preferably, in this embodiment, the first bracket 50 has a plurality of spaced-apart mounting holes, and any two mounting holes can be selected according to the actual situation, and the limiting member 60 is fixed by fasteners. Of course, in other embodiments not shown in the figure, the transformer further includes a mounting plate. The mounting plate and the limiting member are clamped on both sides of the clamping member 30. When the position needs to be adjusted, the mounting plate and the limiting member can be loosened. After the position adjustment is completed, the mounting plate and the limiting member can be fastened again.

[0036] As Figures 1 to 4 shown, in this embodiment, the transformer further includes: a wind baffle 70 and a second bracket 80. Among them, the wind baffle 70 has three avoidance holes, and the three coils 10 are respectively threaded through the three avoidance holes. The second bracket 80 is fixedly arranged on the clamping member 30 and is connected to the wind baffle 70 to support the wind baffle 70, and the first bracket 50 is connected to the second bracket 80. In the above structure, the first bracket 50 is connected to the second bracket 80 that supports the wind baffle 70. Utilizing the existing structure of the transformer, there is no need to separately provide a fixing member for fixing the first bracket 50, thereby reducing the number of components of the transformer and lowering the production cost.

[0037] As Figures 1 to 3As shown, in this embodiment, the second bracket 80 includes a plurality of vertically arranged columns 81 spaced apart from each other and a first crossbar 82 connecting the middle parts of the plurality of columns 81. The first bracket 50 is a second crossbar, and the second crossbar is arranged above the columns 81. The second crossbar and the columns 81 are fixed to the clamping member 30 through a connecting member 90. The above structure enables the first bracket 50 and the second bracket 80 to be fixed to the clamping member 30 through the same connecting member 90, reducing the number of connecting members. On the one hand, the production cost is reduced, and on the other hand, the assembly efficiency is improved.

[0038] It should be noted that, in this embodiment, the specific setting position of the second crossbar (the first bracket 50) can be adjusted in the up and down direction according to actual needs. In addition, in other embodiments not shown in the figure, the first bracket may include a plurality of second crossbars arranged in parallel.

[0039] As Figure 2 and Figure 3 shown, in this embodiment, the connecting member 90 includes a horizontally arranged L-shaped connecting plate 91 and a fastening member. The upper part of the column 81 and the second crossbar are connected to the end plate of the L-shaped connecting plate 91 through the fastening member. The above structure is simple and convenient for assembly.

[0040] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, in this embodiment, the transformer further includes: a copper bar 100 and a support plate 110. Among them, there are three copper bars 100 arranged in one-to-one correspondence with the insulators 40, and the end portions of the wires 11 of each coil 10 are connected to the corresponding copper bars 100; there are three support plates 110 arranged in one-to-one correspondence with the insulators 40, which are arranged on the clamping member 30, and both ends of each insulator 40 are connected to the corresponding copper bar 100 and the support plate body 111. The inventor found that, according to actual needs, the position of the copper bar 100 may need to be arranged at a high position, which not only causes the wire 11 to become longer, but also causes the support plate 110 to become longer. Once the support plate 110 becomes longer, its strength is affected. On the one hand, it causes the support plate 110 to be easily damaged, and on the other hand, it causes the support plate 110 to be easily shaken during transportation, thereby causing the insulator 40 connected thereto to shake. The shaking of the insulator 40 will cause the wire 11 to be easily shaken, thus increasing the risk of wire breakage. To solve the above problems, in this embodiment, the support plate 110 includes a support plate body 111 extending upward and a strengthening structure provided on the support plate body 111. The above strengthening structure can strengthen the strength of the support plate 110, thereby on the one hand ensuring the service life of the support plate 110 and on the other hand reducing the risk of wire breakage.

[0041] As Figure 5As shown, in this embodiment, the support plate body 111 includes a horizontal plate 112 and a vertical plate 113 that are perpendicular to each other. The horizontal plate 112 is connected to the clamping member 30, and the vertical plate 113 extends upward. The insulator 40 is connected to the upper end of the vertical plate 113. The strengthening structure includes a first strengthening structure 114 disposed between the horizontal plate 112 and the vertical plate 113, and / or the strengthening structure includes a second strengthening structure 115 disposed between the clamping member 30 and the horizontal plate 112. Specifically, the first strengthening structure 114 enhances the strength of the support plate 110 itself, and the second strengthening structure 115 enhances the strength of the connection between the support plate 110 and the clamping member 30.

[0042] As Figure 5 shown, both the first strengthening structure 114 and the second strengthening structure 115 are reinforcing ribs. The above structure is simple and easy to process.

[0043] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0044] For the sake of convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation of the device shown in the figure. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0045] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0046] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
