Description

Technical Field

[0001] This utility model relates to the field of transformers, specifically to server transformers. Background Technology

[0002] Choosing the right transformer is crucial for server operation. Servers typically use AC power, and the mains voltage in most areas is 220V or 110V. Therefore, servers need a transformer to convert the voltage to a suitable level for server operation.

[0003] The transformer is mounted on a circuit board. The coil leads of the transformer are connected to the transformer terminals. The coil leads connected to the terminals are exposed and are easily affected by the external environment, such as the influence of external humidity, the magnetic field or heat of the electronic components around the transformer. Utility Model Content

[0004] The technical problem solved by this utility model is: how to avoid exposing the coil lead-out end connected to the terminal.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency server miniature transformer, including a wire frame and an iron core, and a coil wound on the wire frame. The iron core passes through the wire frame, which is horizontal. A base is provided at the bottom of the wire frame, and terminals are provided on the side of the base. A lead wire groove is provided at the bottom of the base. The iron core is fitted on the base, and the lead end of the coil extends downward, passes through the lead wire groove, and connects to the terminal.

[0006] According to the above technical solution, the coil lead-out end is hidden in the lead groove at the bottom of the base, and the base is mounted on the circuit board. In this way, the coil lead-out end is hidden, avoiding the influence of the external environment on the coil lead-out end.

[0007] The transformer frame and base are integrally formed, and a limiting platform is provided at the connection between the base and the frame. The iron core fits onto the limiting platform. That is, while the iron core is engaged with the frame, it presses against the limiting platform, thus stabilizing the transformer structure.

[0008] The wire frame includes a left limiting edge and a right limiting edge, and the base includes a left base and a right base. The left limiting edge and the left base are integrally formed, and the right limiting edge and the right base are integrally formed. The coil is located between the left limiting edge and the right limiting edge, and also between the left base and the right base. This design ensures that the wire harness is not interfered with during coil winding, and also facilitates coil heat dissipation after the coil is wound.

[0009] A longitudinal through groove is formed between the left base and the right base, and the lead wire groove is set laterally. The longitudinal through groove intersects with several lead wire grooves. The airflow enters the coil through the longitudinal and transverse through grooves and lead wire grooves to dissipate heat from the coil.

[0010] The iron core includes a left E-shaped iron core and a right E-shaped iron core. The left and right E-shaped iron cores are spliced ​​on the left and right sides of the coil frame. The iron core is open from top to bottom, forming a vertical airflow. The intersecting through slots and lead slots form a horizontal airflow. The vertical and horizontal airflows converge, which is conducive to the ventilation and heat dissipation of the coil.

[0011] This utility model has the following technical effects:

[0012] First, the coil leads are hidden to prevent them from being affected by the external environment.

[0013] Secondly, the transformer structure can create a convergence of vertical and horizontal airflow, which is beneficial for the ventilation and heat dissipation of the coils.

[0014] Third, transformers have good heat dissipation capabilities, which can improve efficiency. Attached Figure Description
