Furthermore, by setting the width of the first insertion slot to be greater than the width of the second insertion slot, the snap-fit component first enters the wider first insertion slot during assembly and then enters the narrower second insertion slot. This makes assembly smoother, reduces assembly difficulty, and improves assembly efficiency. Attached Figure Description

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0038] like Figures 1-6 As shown, this embodiment of the utility model provides a transformer structure, including a transformer body 1 and an installation component 2.
[0039] The mounting assembly 2 includes a connecting plate 21, a mounting fixing plate 22, and a fastener 23. One side of the connecting plate 21 is connected to the transformer body 1. The mounting fixing plate 22 is connected to the other side of the connecting plate 21, and the side of the mounting fixing plate 22 facing away from the connecting plate 21 is provided with a first insertion groove 221, a second insertion groove 222, and a first snap-fit protrusion 223 distributed at intervals along a first direction. The width of the first insertion groove 221 along a second direction is greater than the width of the second insertion groove 222 along a second direction. The latching member 23 is slidably inserted into the first insertion groove 221 and the second insertion groove 222 along a first direction. An elastic member 24 is provided between the latching member 23 and the mounting plate 22. A second engaging protrusion 2312a is provided at the end of the latching member 23 near the second insertion groove 222. The elastic member 24 provides a sliding force for the latching member 23 toward the first engaging protrusion 223, so that the guide rail 100 can be elastically engaged between the first engaging protrusion 223 and the second engaging protrusion 2312a. The first direction is perpendicular to the extension direction of the guide rail 100, and the second direction is the same as the extension direction of the guide rail 100.
[0040] In this transformer structure, the transformer body 1 can be snapped onto the guide rail 100 via the mounting assembly 2. Specifically, the snap fastener 23 slides into the first insertion groove 221 and the second insertion groove 222, and an elastic element 24 is provided between it and the mounting plate 22. Under the elastic force of the elastic element 24, the snap fastener 23 has a sliding force toward the first snap protrusion 223, so that the guide rail 100 can be snapped between the first snap protrusion 223 and the second snap protrusion 2312a. The installation operation is convenient and the cost is low. In addition, by setting the width of the first insertion groove 221 to be greater than the width of the second insertion groove 222, the snap fastener 23 first enters the wider first insertion groove 221 and then enters the narrower second insertion groove 222 during assembly, making the snap fastener 23 easier to assemble, reducing assembly difficulty and improving assembly efficiency.
[0041] Optionally, the connecting plate 21 and the transformer body 1 can be connected by bolts or screws, and the mounting plate 22 and the connecting plate 21 can also be connected by screws or bolts.
[0042] Optionally, such as Figures 2-4 As shown, the mounting plate 22 is provided with two first sliding parts symmetrically distributed along the second direction, and a first insertion groove 221 is formed between the two symmetrically distributed first sliding parts. The mounting plate 22 is also provided with two second sliding parts symmetrically distributed along the second direction, and a second insertion groove 222 is formed between the two second sliding parts. The fastener 23 is simultaneously slidably disposed between the two first sliding parts and between the two second sliding parts, and the distance between the two first sliding parts is greater than the distance between the two second sliding parts, so that the fastener 23 slides into the distance between the two first sliding parts more smoothly. After entering the distance between the two first sliding parts, the two first sliding parts form a certain guiding effect on the fastener 23, so that the fastener 23 slides into the distance between the two second sliding parts more smoothly.
[0043] Specifically, the fastening element 23 includes a fastening main body 231 and extensions 232 disposed on both sides of the fastening main body 231 along a second direction. The two sides of the fastening main body 231 along the second direction slide onto two second sliding portions, and the two extensions 232 slide onto two first sliding portions. An elastic element 24 is disposed between the fastening main body 231 and the mounting plate 22. By providing extensions 232 on both sides of the fastening main body 231, the width of the two extensions 232 along the second direction is greater than the width of the fastening main body 231 along the second direction, allowing the fastening main body 231 to match the two second sliding portions and the two extensions 232 to match the two first sliding portions, resulting in a more rational structural design.
[0044] More specifically, the first sliding part includes a first vertical plate 2211 and a first horizontal plate 2212 that are perpendicularly distributed to each other. The first vertical plate 2211 is vertically disposed on the mounting plate 22, and the two first horizontal plates 2212 extend towards each other. The extension part 232 is slidably connected between the corresponding first horizontal plate 2212 and the mounting plate 22. The second sliding part includes a second vertical plate 2221 and a second horizontal plate 2222 that are perpendicularly distributed to each other. The second vertical plate 2221 is vertically disposed on the mounting plate 22, and the two second horizontal plates 2222 extend towards each other. The side of the buckle body 231 is slidably connected between the corresponding second horizontal plate 2222 and the mounting plate 22. This structure allows the buckle 23 to slide with the first sliding part and the second sliding part to limit the buckle 23, so that the buckle 23 can only slide in the first direction and cannot swing in the second direction or detach from the first sliding part or the second sliding part.
[0045] The main body 231 of the buckle includes a main board 2311 and support plates 2312 disposed on both sides of the main board 2311 along a second direction. Two extensions 232 are disposed on both sides of the main board 2311 along the second direction. The extensions 232 and the support plates 2312 on the same side are spaced apart along a first direction. When the buckle 23 slides into the first insertion groove 221 and the second insertion groove 222, the two support plates 2312 slide against the mounting plate 22, the main board 2311 slides into contact with the second horizontal plate 2222, and the extensions 232 slide into contact with the first horizontal plate 2212. This structural design can reduce the contact area between the buckle 23 and the mounting plate 22, reduce wear, and improve the smoothness of sliding.
[0046] Furthermore, the distance between the two first horizontal plates 2212 is greater than the distance between the two second vertical plates 2221, and the two support plates 2312 are confined between the two first horizontal plates 2212. During the assembly of the fastener 23, the fastener body 231 firstly slides easily between the two first horizontal plates 2212, so that the two first horizontal plates 2212 guide and limit the fastener 23. Then, the fastener body 231 slides between the two second vertical plates 2221, so that the two second vertical plates 2221 limit the fastener body 231 in the second direction to prevent the fastener 23 from swinging. At the same time, the extension 232 slides into the first sliding insertion part, so that the first vertical plate 2211 limits the extension 232 in the second direction. The first horizontal plate 2212 and the extension 232 slide in contact, further ensuring the stability of the fastener 23.
[0047] Optionally, each of the two support plates 2312 has a second snap-fit protrusion 2312a at its end, and the mounting plate 22 has two first snap-fit protrusions 223 spaced apart along the second direction. The guide rail 100 is snapped between the two first snap-fit protrusions 223 and the two second snap-fit protrusions 2312a.
[0048] Furthermore, the first snap-fit protrusion 223 is provided with a first slot 2231, and the second snap-fit protrusion 2312a is provided with an inclined surface 2312b on the side facing the mounting plate 22. The inclined surface 2312b and the mounting plate 22 form a second slot, and the two ends of the guide rail 100 along its width direction can be respectively inserted into the first slot 2231 and the second slot.
[0049] Optionally, the motherboard 2311 and the mounting plate 22 are respectively provided with a first bending plate 2311a and a second bending plate 224 that are relatively distributed. The first bending plate 2311a and the second bending plate 224 are bent towards each other, and the first bending plate 2311a and the second bending plate 224 are respectively provided with a first protrusion 2311a1 and a second protrusion 2241 at one end facing each other. The two ends of the elastic member 24 are respectively sleeved on the first protrusion 2311a1 and the second protrusion 2241 and elastically abut against the first bending plate 2311a and the second bending plate 224. By providing the first bending plate 2311a and the second bending plate 224, the elastic member 24 is installed more stably.
[0050] Optionally, the elastic element 24 can be selected as a compression spring, and the two ends of the compression spring can be respectively sleeved on the first bending plate 2311a and the second bending plate 224.
[0051] Optionally, the motherboard 2311 is also provided with a raised groove 2311b that is arched and facing away from the mounting plate 22, and the elastic element 24 extends into the raised groove 2311b to avoid interference between the elastic element 24 and the snap-fit element 23.
[0052] Optionally, the motherboard 2311 is also provided with a handle groove 2311c, which allows for easy manual pulling of the buckle 23, making it easier to connect with the guide rail 100.
[0053] When the mounting component 2 is not connected to the guide rail 100, in order to prevent the buckle 23 from sliding out under the elastic force of the elastic member 24, a limit block 2321 is provided on the opposite side of the two extensions 232. The limit block 2321 is located at the end of the extension 232 near the first insertion groove 221. Under the force of the elastic member 24, the two limit blocks 2321 can abut against the two first sliding parts to limit the buckle 23 from sliding out.
[0054] In this embodiment, as Figures 5-6 and combined Figure 1As shown, the transformer body 1 includes a housing 11, a coil frame 12, and terminals 13. The housing 11 is mounted on a connecting plate 21 by screws or bolts. The coil frame 12 is mounted on the housing 11 and has a plug-in portion 121. Two plug-in portions 121 can be provided and are symmetrically distributed along a second direction. Each plug-in portion 121 has a through-hole 1211 on its opposite side. The through-hole 1211 passes through the plug-in portion 121 along a third direction. Each plug-in portion 121 has at least one terminal 13. The terminal 13 has a plug plate 131. The end of the plug plate 131 has a hook 1311. The plug plate 131 is inserted into the through-hole 1211. The hook 1311 can abut against the lower end of the plug-in portion 121 to prevent the plug plate 131 from coming out of the through-hole 1211.
[0055] The first direction, the second direction, and the third direction are perpendicular to each other.
[0056] Of course, for ease of installation, each terminal block 13 can be provided with multiple insert plates 131, and the plug-in portion 121 can be provided with multiple through holes 1211, so that the multiple insert plates 131 on each terminal block 13 can be inserted into the multiple through holes 1211 on the corresponding plug-in portion 121. Furthermore, in order to facilitate the installation of the terminal block 13 at different positions of the plug-in portion 121, each plug-in portion 121 can be provided with more through holes 1211 than the number of insert plates 131 on the corresponding terminal block 13, so that the terminal block 13 can be installed in any through hole 1211.
[0057] Optionally, the side of the plug portion 121 that is in contact with the terminal 13 is provided with a plurality of recessed grooves 1212 spaced apart along a first direction. The recessed grooves 1212 penetrate the plug portion 121 along a third direction. When the terminal 13 is connected to the plug portion 121, the side of the terminal 13 is in contact with the side of the plug portion 121. By opening the recessed grooves 1212 on the side of the plug portion 121, the contact area between the terminal 13 and the plug portion 121 can be reduced, improving the firmness of the installation and the smoothness of the installation process. At the same time, the recessed grooves 1212 are also conducive to ventilation, so as to remove the heat of the terminal 13 and the coil frame 12.
