Description

Technical Field

[0001] The utility model relates to the technical field of transformer manufacturing, and particularly relates to a new plastic skeleton. Background Art

[0002] At present, the skeleton structure of the transformer adopts a simple skeleton, with an epoxy board added in the middle for isolation. The epoxy board used for isolation is not resistant to high temperature and is prone to deformation generally at about 130°C; the cost is high; the structure is not firm and glue is needed for bonding; the surface of the epoxy board material is relatively smooth and it is easy to break away after glue bonding, affecting the stability of the transformer. Therefore, there is an urgent need for a new plastic skeleton to solve the above problems. Summary of the Invention

[0003] The purpose of the utility model is to provide a new plastic skeleton to solve the technical problems such as easy deformation, high cost, and insecure structure (requiring glue bonding) of the existing new plastic skeleton.

[0004] A new plastic skeleton of the utility model includes a bottom plate and side plates. A coil and a magnetic core are installed on the skeleton. Among them, the coil is wound around the periphery of the skeleton, the magnetic core is clamped inside the skeleton, the skeleton is integrally formed, and the middle part thereof is a hollow cavity. The skeleton includes a support, a left side plate arranged on one side of the support, a right side plate arranged on the other side of the support, and a partition arranged in the middle of the support.

[0005] Preferably, mounting plates are provided at the lower parts of the left side plate and the right side plate. The mounting plates are in a "mountain" shape, with both ends protruding outward to form support plates and the middle part protruding outward to form clamping plates. The clamping plates are clamped in the holes of the bottom plate.

[0006] Preferably, a heat dissipation channel is formed between the support plates and the clamping plates.

[0007] Preferably, gaps are provided at the upper side edges of the left side plate and the right side plate.

[0008] Preferably, the skeleton is made of plastic material.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] This novel plastic skeleton and base include a support frame, a left side plate, a right side plate, and partitions. The support frame is the main structure of the skeleton, with an internal hollow cavity for fixing the magnetic core and an external cavity for winding the coils. The left and right side plates are located on the left and right sides of the support frame, respectively, and are used to limit the windings. In addition, the left and right side plates are also snapped together with the bottom plate to ensure the stability of the skeleton installation. By integrally molding the partitions in the middle of the support frame, it is possible to avoid the need for adhesive during installation, ensuring the dimensional standard of the double grooves formed on the outside. Furthermore, the skeleton is integrally molded, which achieves the effects of improving skeleton production efficiency, reducing costs, and improving product structural stability.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] like Figure 1-2 As shown, this utility model discloses a novel plastic frame with a coil and a magnetic core installed on it. The coil is wound around the periphery of the frame 1, and the magnetic core is clamped inside the frame 1. The frame 1 is integrally formed, and its middle part is a hollow cavity 10. The frame includes a support 11, a left side plate 12 on one side of the support, a right side plate 13 on the other side of the support, and a partition 14 in the middle of the support.

[0017] This utility model discloses a novel plastic frame, primarily serving to fix the internal winding wires of a transformer and support the transformer body. The frame 1 includes a support 11, a left side plate 12, a right side plate 13, and a partition 14. The support 11 is the main structure of the frame, with an internal hollow cavity 10 for fixing the magnetic core and an external cavity for winding the coils. The left side plate 12 and right side plate 13 are located on the left and right sides of the support 11, respectively, for limiting the windings. Furthermore, the left side plate 12 and right side plate 13 are also snapped together with the bottom plate to ensure the stability of the frame installation. By integrally molding the partition 14 in the middle of the support, it eliminates the need for adhesive during installation, ensuring the dimensional standard of the double grooves formed externally. Additionally, the frame is integrally molded, achieving the effects of improving frame production efficiency, reducing costs, and enhancing product structural stability.

[0018] In a preferred embodiment, refer to Figure 1-2 The novel plastic frame has mounting plates at the lower part of the left side plate 12 and the right side plate 13. These mounting plates are "mountain" shaped, with both ends protruding outwards to form support plates 131 and the middle protruding outwards to form a retaining plate 132, which is secured in a hole in the base plate. A heat dissipation channel 133 is formed between the support plate 131 and the retaining plate 132. Notches 121 are provided on the upper sides of the left side plate 12 and the right side plate 13. The frame 1 is made of plastic material.

[0019] By setting a "mountain"-shaped mounting plate at the lower part of the left side plate 12 and the right side plate 13, with both ends protruding outward to form a support plate 131, the bottom of the support plate 131 is a support surface that contacts the surface of the base plate during installation. The frame has a total of four support surfaces, which can ensure that the frame is flat and stable after assembly with the base plate. A clamping plate 132 protrudes outward from the middle of the left side plate 12 and the right side plate 13. During installation, the clamping plate 132 is inserted into the hole of the base plate to prevent the frame from shifting position during assembly with the base plate, further improving the assembly efficiency of the transformer. A heat dissipation channel 133 is formed between the support plate 131 and the clamping plate 132, which improves the heat dissipation efficiency of the transformer. A notch 121 is provided on the upper side of the left side plate 12 and the right side plate 13 to ensure that the temperature sensing wire of the transformer can be led out through the notch, which facilitates assembly.

[0020] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
