Description

Technical Field

[0001] The utility model relates to the field of transformers, in particular to a special transformer for power supply. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It can convert AC power of one voltage level into AC power of another voltage level with the same frequency through electromagnetic induction between coils.

[0003] The transformer is mainly composed of a primary coil, a secondary coil and an iron core. The diameter of the coil conductor is proportional to the current passing through the conductor, that is, the thicker the conductor, the greater the current that can pass through. The existing power supply transformer is small in size, and the iron core inside the transformer is generally an integrated structure. In order to facilitate coil winding, a thinner wire is generally selected for winding (a thicker wire is not easy to wind on an integrated iron core). This structure will limit the current passing through and is not convenient to use. Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and provides a special transformer for power supply.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a power supply dedicated transformer, including a winding mechanism, a connecting mechanism is installed on the winding mechanism, the winding mechanism includes a bottom plate, the upper surface of the bottom plate is fixedly connected to an outer column, the number of the outer columns is two, a limiting plate is installed inside the outer column, the upper surface of the limiting plate is fixedly connected to a limiting buckle, and the number of the limiting buckles is multiple, a metal barb is provided on the top of the limiting buckle, the connecting mechanism includes a top plate, the top plate is located above the outer column, the lower surface of the top plate is fixedly connected to a connecting column, the connecting column is installed inside the outer column, the outer surface of the connecting column is provided with a connecting groove, and the metal barb is located inside the connecting groove.

[0006] As a further description of the above technical solution:

[0007] The upper surface of the bottom plate is provided with threaded holes, the number of the threaded holes is two, and the two threaded holes are respectively located inside the two outer columns.

[0008] As a further description of the above technical solution:

[0009] A connecting hole is provided on the surface of the limiting plate, and the connecting hole is located directly above the threaded hole.

[0010] As a further description of the above technical solution:

[0011] A connecting screw is installed inside the connecting hole, and the bottom of the connecting screw is connected to the inner thread of the threaded hole.

[0012] As a further description of the above technical solution:

[0013] A notch is formed at the bottom of the connecting column, and the top of the connecting screw is located inside the notch.

[0014] As a further description of the above technical solution:

[0015] A first coil is installed on the outer surface of one of the outer columns, and a second coil is installed on the outer surface of the other outer column.

[0016] The utility model has the following beneficial effects:

[0017] Compared with the prior art, the power supply dedicated transformer, through the winding mechanism and the connecting mechanism, can first wind the first coil and the second coil on the outer column when in use, and then install the connecting column on the connecting mechanism into the inner part of the outer column. After the connecting column enters the inner part of the outer column, the connecting column is pressed downward, which will first squeeze the metal barb on the top of the limit buckle to deform it inward, and continue to press the metal barb downward to enter the connecting groove on the connecting column. At this time, the metal barb loses pressure, and the metal barb itself has a certain elasticity and will recover and be stuck in the connecting groove, thereby fixing the connecting column inside the outer column, so that the winding mechanism and the connecting mechanism cooperate to form a complete closed iron core structure. Compared with the existing power supply dedicated transformer, the volume is smaller, and the iron core inside the transformer is generally an integrated structure. In order to facilitate coil winding, a thinner wire diameter is generally selected for winding, which limits the current passing through and is not convenient to use. When using the power supply dedicated transformer, the connecting mechanism can be used without assembling the connecting mechanism first, leaving enough space on the outer column to facilitate the first coil and the second coil with a thicker wire diameter to be wound on the outer column, so that the transformer can pass a larger current.

When in use, the connecting column 202 on the connecting mechanism 2 is installed inside the outer column 102. After the connecting column 202 enters the inside of the outer column 102, the connecting column 202 is pressed downward. The connecting column 202 will first squeeze the metal barb on the top of the limiting buckle 106, causing it to deform inward. Continuing to press downward, the metal barb will enter the connecting groove 203 on the connecting column 202. At this time, the metal barb loses pressure, and the metal barb itself has a certain elasticity and will recover and get stuck in the connecting groove 203, thereby fixing the connecting column 202 inside the outer column 102, so that the winding mechanism 1 and the connecting mechanism 2 cooperate to form a complete closed iron core structure.

[0026] A threaded hole 103 is provided on the upper surface of the base plate 101. There are two threaded holes 103, which are respectively located inside the two outer columns 102. A connecting hole 105 is provided on the surface of the limiting plate 104. The connecting hole 105 is located directly above the threaded hole 103. A connecting screw 107 is installed inside the connecting hole 105. The bottom of the connecting screw 107 is connected to the internal thread of the threaded hole 103. The limiting plate 104 can be fixed to the base plate 101 by the connecting screw 107. A recess 204 is provided at the bottom of the connecting column 202.

[0027] A first coil 3 is installed on the outer surface of one outer column 102, and a second coil 4 is installed on the outer surface of another outer column 102. When in use, the first coil 3 and the second coil 4 are wound on the outer column 102, one coil serves as a primary coil, and the other coil serves as a secondary coil. By utilizing the electromagnetic induction effect between the two coils, AC power of one voltage level can be converted into AC power of another voltage level of the same frequency.

[0028] Working principle: When in use, first wind the first coil 3 and the second coil 4 on the outer column 102, and then install the connecting column 202 on the connecting mechanism 2 into the inside of the outer column 102. After the connecting column 202 enters the inside of the outer column 102, press the connecting column 202 downward, and the connecting column 202 will first squeeze the metal barb on the top of the limit buckle 106 to deform it inward. Continuing to press down the metal barb will enter the connecting groove 203 on the connecting column 202. At this time, the metal barb loses pressure, and the metal barb itself has a certain elasticity and will recover and get stuck in the connecting groove 203, thereby fixing the connecting column 202 inside the outer column 102, so that the winding mechanism 1 and the connecting mechanism 2 cooperate to form a complete closed iron core structure. When using the power-specific transformer, the connecting mechanism 2 can be assembled first without first leaving enough space on the outer column 102 to facilitate the first coil 3 and the second coil 4 with thicker wire diameters to be wound around the outer column 102, so that the transformer can pass a larger current.
