Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically a power transformer. Background Technology

[0002] A power transformer is a common electrical device whose main function is to change AC voltage. It works based on the principle of electromagnetic induction and consists of a primary coil, a secondary coil, and an iron core. It is mainly used in various electronic devices, such as household appliances, computers, and communication equipment.

[0003] Power transformers are typically soldered onto circuit boards via pins. Due to space limitations of components on the circuit board, power transformers sometimes need to be installed horizontally and sometimes vertically. However, the pins of existing power transformers are fixed, and the installation direction is fixed. Therefore, different models of power transformers are required when installing in different orientations, resulting in poor compatibility. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 5This utility model provides a technical solution: a power transformer, including a transformer body 1 and a plurality of first pins 2 disposed on the transformer body 1. The transformer body 1 is prior art and will not be described in detail. A transfer mechanism 3 is detachably installed on the outside of the transformer body 1. The transfer mechanism 3 includes a horizontal plate 31 and a vertical plate 32. The top of the horizontal plate 31 is provided with a plurality of insulating cylinders 34 corresponding to the first pins 2. The insulating cylinders 34 are used to provide insulation protection for the connecting cylinders 35. The inside of the insulating cylinders 34 is provided with connecting cylinders 35 that cooperate with the first pins 2. The first pins 2 are inserted into the connecting cylinders 35 to achieve connection with the connecting cylinders 35. The connection between the connecting sleeves 35 is achieved by the first pin 2 being electrically connected to the second pin 37 through the connecting sleeve 35 and the connector 36. The second pin 37 is provided on one side of the vertical plate 32 and is vertically arranged with the first pin 2, so that the transformer body 1 can be installed horizontally or vertically, improving the convenience of installation. The second pin 37 and the connecting sleeve 35 are provided with a connector 36. The second pin 37, the connector 36 and the connecting sleeve 35 are integrally formed, and the materials of the second pin 37, the connector 36 and the connecting sleeve 35 are all conductive metals. The horizontal plate 31 is provided with a sleeve 33.

[0021] The bottom of the transformer body 1 is provided with a plug 7 that is interference-fitted with the plug sleeve 33. The plug 7 and the plug sleeve 33 are interference-fitted to realize the connection and fixation between the transformer body 1 and the transfer mechanism 3.

[0022] The docking cylinder 35 has an insertion hole 5 in the middle. The insertion hole 5 facilitates the insertion of the first pin 2 into the docking cylinder 35.

[0023] The vertical plate 32 has a second protrusion 6 on one side, and the transformer body 1 has a first protrusion 4 at the four corners of the bottom. The first protrusion 4 creates a certain gap when the transformer body 1 is installed on the circuit board or the horizontal plate 31, so as to facilitate heat dissipation.

[0024] Among them, the horizontal plate 31, the vertical plate 32, the insert 33 and the insulating cylinder 34 are integrated injection molded structures, which ensures a firm connection and facilitates production and manufacturing.

[0025] Specifically, when longitudinal installation is required, first take out the transformer body 1 and bring it close to the horizontal plate 31. Insert the plug 7 into the plug sleeve 33 and insert the first pin 2 into the plug hole 5 until the first protrusion 4 is pressed against the horizontal plate 31. The transformer body 1 is then installed in place. At this time, the plug 7 and the plug sleeve 33 are interference-fitted to achieve the connection and fixation between the transformer body 1 and the horizontal plate 31. The first pin 2 is electrically connected to the second pin 37 through the docking cylinder 35 and the connector 36. Then, the second pin 37 is soldered to the circuit board to achieve longitudinal installation. When transverse installation is required, separate the transformer body 1 from the adapter mechanism 3 and solder the first pin 2 to the circuit board to achieve transverse installation.
