Description

Technical Field

[0001] This application relates to the field of transformers, and in particular to a transformer that is easy to install. Background Technology

[0002] Small transformers are characterized by their small size, low cost, and minimal wiring requirements. They generally have lower load rates and utilization rates, and the inductive loads they carry are typically not capacitively compensated. Small transformers are a common piece of equipment in factory electrical control systems. With the increasing use of electronic components in power plant control, monitoring, and automatic circuits, market demand has increased, leading to the increasingly widespread application of small transformers.

[0003] Most small transformers are typically installed on distribution cabinets. They are secured inside the distribution cabinet using bolts. However, because there are many electrical components inside the cabinet, installers must be extremely careful during installation to avoid accidentally touching other components. Furthermore, drilling holes in the distribution cabinet is challenging due to variations in hole dimensions, making it difficult to align the holes on the transformer with those in the distribution cabinet, thus delaying the installation process. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a transformer that is easy to install. It allows for convenient installation of the transformer onto a distribution cabinet.

[0006] A transformer that is easy to install includes a fixing clip, a frame is provided inside the fixing clip, a winding and a terminal connected to the winding are provided inside the frame, a connecting plate is fixedly provided on both sides of the fixing clip, an extension plate is slidably provided on the connecting plate, the connecting plate has a connecting hole, the extension plate has a first waist-shaped groove communicating with the connecting hole, the extension plate and the connecting plate are anti-detached, and the length direction of the first waist-shaped groove is the same as the sliding direction of the extension plate.

[0007] Preferably, the first waist-shaped groove has an opening.

[0008] Preferably, the extension plate has a guide groove, and the connecting plate has a guide block fixed thereon, the guide block being located within the guide groove.

[0009] Preferably, the top of the guide block is also fixed with an anti-detachment part.

[0010] Preferably, the terminal block is rotatably provided with a bolt, and the bolt is threadedly connected to a clamping plate. Rotation of the bolt can force the clamping plate away from or closer to the terminal block.

[0011] Preferably, the clamping plate has a transverse U-shaped limiting groove.

[0012] Preferably, the clamping plate has a longitudinal U-shaped limiting groove, which is connected to the transverse U-shaped limiting groove.

[0021] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," "third," and similar expressions are used for descriptive and distinguishing purposes only and should not be construed as indicating or implying the relative importance of the corresponding components.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3This application will be described in further detail.

[0023] This application discloses a transformer that is easy to install.

[0024] A transformer that is easy to install includes a fixing clip 1, a frame 2 is provided inside the fixing clip 1, a winding 3 and a terminal block 4 connected to the winding 3 are provided inside the frame 2, the terminal block 4 is divided into upper and lower layers, the upper layer of terminal blocks 4 has three terminals and the lower layer of terminal blocks 4 has two terminals.

[0025] The fixing clamp 1 has two connecting plates 11 fixedly installed on both sides. One of the connecting plates 11 has an extension plate 13 slidably mounted on it, and the extension plate 13 is anti-detached from the connecting plate 11. The connecting plate 11 has a connecting hole 12, and the extension plate 13 has a first oblong groove 14 communicating with the connecting hole 12. In this application, the first oblong groove 14 has an opening 15. After the screw passes through the connecting hole 12 and the first oblong groove 14, it can be fixedly connected to the distribution cabinet. The length direction of the first oblong groove 14 is the same as the sliding direction of the extension plate 13. When the hole spacing in the distribution cabinet is too long, the extension plate 13 can be pulled open. At this time, the bolt 41 will leave the first oblong groove 14 from the opening 15. However, because the extension plate 13 and the connecting plate 11 are anti-detached, the bolt 41 can still fix the transformer after the screw is tightened.

[0026] The specific structure of the anti-detachment mechanism is as follows: the extension plate 13 has a guide groove 17, and the connecting plate 11 is fixed with a guide block 18, which is located within the guide groove 17. An anti-detachment part 19 is also fixed to the top of the guide block 18. The guide block 18 can slide within the guide groove 17, and the anti-detachment part 19 can prevent the connecting plate 11 and the extension plate 13 from detaching from each other.

[0027] The connecting plate 11 also has a second waist-shaped groove 16, the length direction of the first waist-shaped groove 14 is perpendicular to the length direction of the second waist-shaped groove 16. The length of the second waist-shaped groove 16 can be used to adjust the position of the transformer.

[0028] The first waist-shaped slot 14 and the second waist-shaped slot 16 are perpendicular to each other, which can increase the adjustment range of the transformer position.

[0029] The terminal 4 is rotatably provided with a bolt 41, and the bolt 41 is threadedly connected to a clamping plate 42. Rotation of the bolt 41 can force the clamping plate 42 to move away from or closer to the terminal 4. The clamping plate 42 has a transverse U-shaped limiting groove 43. The clamping plate 42 also has a longitudinal U-shaped limiting groove 44, which communicates with the transverse U-shaped limiting groove 43.

[0030] The implementation principle of the embodiment is as follows: the staff can first install the transformer with screws onto the distribution cabinet, then pass the wire through the horizontal U-shaped limiting groove 43 or the vertical U-shaped limiting groove 44, and then tighten the bolt 41 to clamp the wire with the clamping plate 42, thereby achieving rapid installation.

[0031] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the above specific embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
