Description

Technical Field

[0001] The utility model belongs to the technical field of electronic components, and in particular relates to a transformer structure. Background Art

[0002] Transformers are devices that use the principle of electromagnetic induction to change AC voltage. As a key electrical device, they are widely used in various power adapters and power systems. The design of transformers usually needs to consider factors such as size, efficiency, reliability, and cost in specific applications. However, in specific application scenarios, such as when the cabinet size is limited, traditional transformer designs may not meet space and layout requirements.

[0003] In the prior art, there are usually two ways to layout the primary terminal block and the secondary terminal block: one is to set the two terminal blocks on the same side of the transformer, and the other is to set the two terminal blocks on both sides of the transformer. When the terminal blocks are placed on the same side, it may not be possible to accommodate all the required components due to the space limitations of a specific cabinet. Although setting the terminal blocks on both sides can solve the space problem, it may have an adverse effect on the wiring of the overall structure, increase the wiring complexity, and thus affect the performance and reliability of the transformer. Utility Model Content

[0034] As attached Figure 1-4 As shown, in an illustrative embodiment of a transformer structure of the utility model, the transformer structure includes a transformer body 1, a terminal block fixing clamp 2, a first connecting member 3 and two terminal blocks.

[0035] The transformer body 1 includes three coils 11 arranged in an array and magnetic core blocks 12 arranged at both ends of the coils 11 in the length direction.

[0036] The terminal block fixing clamp 2 is a strip-shaped metal clamp, which is arranged on one side of the transformer body 1 in the width direction opposite to the transformer body 1 and extends along the length direction of the transformer body 1 .

[0037] The first connecting member 3 is L-shaped and used to connect the transformer body 1 and the terminal block fixing clamp 2. One end of the first connecting member 3 is fixedly connected or movably connected to any magnetic core block 12 of the transformer body 1, and the other end is fixedly connected to the terminal block fixing clamp 2 by bolts.

[0038] There are two terminal blocks, namely a primary terminal block 4 and a secondary terminal block 5, and the two terminal blocks are located on the same side of the width direction of the transformer body 1, wherein the primary terminal block 4 is fixed on the end face of the terminal block fixing clamp 2 away from the transformer body 1, and the secondary terminal block 5 is fixed on the end face of the terminal block fixing clamp 2 close to the transformer body 1, that is, in this embodiment, the two terminal blocks are arranged on the same side of the transformer and are respectively fixed on different sides of the terminal block fixing clamp 2.

[0039] The utility model increases the compactness of the overall structure of the transformer and saves installation space by changing the fixed positions of the primary terminal block 4 and the secondary terminal block 5, so that the transformer can meet the space and layout requirements of a specific cabinet.

[0040] In some embodiments of the present invention, in order to enhance the stability of the connection between the terminal block fixing clamp 2 and the transformer body 1 , the L-shaped first connecting member 3 includes two first connecting members 3 , which are arranged in parallel and at intervals.

[0041] In some embodiments of the utility model, the coil 11 includes a primary lead wire and a secondary lead wire, and the primary lead wire and the secondary lead wire are respectively led out from both ends of the length direction of the coil 11, and are respectively extended to be fixed in the wire clamping groove of the primary terminal block 4 and the secondary terminal block 5. The primary lead wire and the secondary lead wire are respectively led out from both ends of the coil 11, and are extended to be fixed in the wire clamping groove of the terminal block, which optimizes the lead layout, reduces the contact resistance between the coil 11 and the terminal block, and improves the reliability of the electrical connection.

[0042] In order to enhance the stability of the transformer structure, in some embodiments of the present invention, a transformer clamp 6 is further included, which is fixed on both sides of the width direction of the magnetic core block 12 along the length direction of the magnetic core block 12, and one end of the first connecting member 3 is connected to the transformer clamp 6. In this embodiment, the clamps on both sides of the magnetic core block 12 at the top of the transformer body 1 are strip clamps, and the clamps on both sides of the magnetic core block 12 at the bottom of the transformer body 1 are L-shaped clamps. The transformer clamps 6 on both sides of the magnetic core block 12 also provide support points for the first connecting member 3 to connect.

[0043] In order to be able to adjust the horizontal distance between the terminal block fixing and the transformer body 1 and improve the flexibility and adjustment space of the transformer installation, some embodiments of the utility model further include a second connecting member 7, which is arranged in a strip shape, the number of which matches the number of the first connecting members 3, one end of which is fixedly connected to the transformer clamp 6, and the other end extends to the outside of the transformer body 1 and is movably connected to the first connecting member 3.

[0044] Furthermore, in order to achieve a movable connection between the first connecting member 3 and the second connecting member 7, a waist-shaped hole is opened at the connecting end of the second connecting member 7 and the first connecting member 3, and the second connecting member 7 is movably connected to the first connecting member 3 by screws at the waist-shaped hole.

[0045] Furthermore, in order to achieve a movable connection between the first connecting member 3 and the second connecting member 7, waist-shaped holes are opened in the first connecting member 3 and the second connecting member 7, and the first connecting member 3 is movably connected to the second connecting member 7 through screws in the waist-shaped holes.

[0046] In order to reduce confusion during wiring and improve the neatness of wiring, in some embodiments of the utility model, the two terminal blocks are respectively fixed at both ends of the length direction of the terminal block fixing clamp 2. At the same time, the symmetrical layout of the two terminal blocks also helps to balance the weight distribution of the transformer and reduce unbalanced stress during installation.

[0047] In order to further reduce confusion during wiring and improve the neatness of wiring, in some embodiments of the utility model, grooves for wiring are opened on two opposite end surfaces of the terminal block fixing clamp 2 close to and away from the transformer body 1, and the two grooves extend along the length direction of the terminal block fixing clamp 2.

[0048] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0049] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
