Background
The high-frequency transformer is the most important component of the switching power supply, generally, the switching power supply generally adopts a half-bridge power conversion circuit, two switching triodes are conducted in turn to generate high-frequency pulse waves during working, and then the high-frequency pulse waves are reduced in voltage through the high-frequency transformer to output low-voltage alternating current.
At present, a primary coil and a secondary coil of a high-frequency transformer are both arranged on a framework, and as shown in fig. 1, the primary coil and the secondary coil perform voltage conversion and energy transmission according to the principle of electromagnetic induction. However, this method has a great problem, for example, when the primary coil or the secondary coil has a problem, the whole high-frequency transformer needs to be disassembled for repair, and the transformation ratio of the high-frequency transformer is fixed and is not flexible enough for use; and when any one of the primary coil and the secondary coil has a fault which cannot be repaired, the whole high-frequency transformer needs to be replaced, so that the cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a high frequency transformer through plug connector combination for poor and with high costs problem of flexibility when solving the high frequency transformer among the prior art and using.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a high-frequency transformer combined by plug connectors comprises plug connectors and a split primary coil and a split secondary coil; the plug connector comprises a partition plate, a first mounting groove and a second mounting groove, and the first mounting groove and the second mounting groove are respectively arranged on two sides of the partition plate; the primary coil may be inserted in the first mounting groove, and the secondary coil may be inserted in the second mounting groove.
The utility model provides a technical scheme sets up primary coil and secondary coil components of a whole that can function independently to adopt the plug connector with primary coil and secondary coil aggregate erection, can change primary coil and secondary coil according to the demand, make high frequency transformer have different transformation ratios, and when one of them breaks down, only need dismantle or change the coil that corresponds can, thereby increase high frequency transformer's flexibility, cost when reducing its use.
In order to prevent the windings of the primary coil and the secondary coil from falling off or being damaged by external equipment, fixing adhesive tapes are arranged on the peripheries of the primary coil and the secondary coil.
In order to prevent mutual interference between the primary coil wiring and the secondary coil wiring, the first mounting groove and the second mounting groove are mounted in opposite directions.

Detailed Description
The present embodiment provides a high-frequency transformer combined by a connector, in which a primary coil and a secondary coil are separately disposed, and the primary coil and the secondary coil are combined and mounted by the connector, so as to increase flexibility of the high-frequency transformer and reduce use cost of the high-frequency transformer.
The high-frequency transformer combined by the plug connector provided by the embodiment has a structure as shown in fig. 1, and includes a primary coil 1, a secondary coil 2, and a plug connector 3.
The plug-in unit 3 includes a partition plate 31, one side of which is provided with a first mounting groove 32 and the other side of which is provided with a second mounting groove 33, and the primary coil 1 may be inserted in the first mounting groove 32 and the secondary coil 2 may be inserted in the second mounting groove 33.
The first mounting groove 32 and the second mounting groove 33 are installed in opposite directions, i.e., if the installation direction is from the left to the right of the connector 3 when the primary coil 1 is installed into the first mounting groove 32, the installation direction is from the right to the left of the connector 3 when the secondary coil 2 is installed into the second mounting groove 33.
A through hole 35 is formed in the partition plate 31, a through hole 11 is formed in the primary coil 1, a through hole 21 is formed in the secondary coil, the through hole 11 of the primary coil 1, the through hole 21 of the secondary coil 2 and the through hole 35 are communicated to form a through hole of the high frequency transformer after the primary coil 1 and the secondary coil 2 are mounted in the first mounting groove 32 and the second mounting groove 33, respectively, and an iron core is disposed in the through hole to increase magnetic fluxes of the primary coil 1 and the secondary coil 2, thereby improving the working efficiency of the high frequency transformer.
In this embodiment, a folded edge 34 is provided on the top of the first mounting groove 32, i.e., on the side corresponding to the position of the partition plate 31, so that the primary coil 1 can be prevented from sliding out of the first mounting groove 32 by the limiting action of the folded edge 34 after the primary coil 1 is mounted in the first mounting groove 32.
In the present embodiment, the folded edge is provided only at the top of the first mounting groove 32, and as other embodiments, the folded edge may be provided only at the top of the second mounting groove 33 to prevent the secondary coil from sliding down from the second mounting groove 33, or the folded edges may be provided at both the tops of the first mounting groove 32 and the second mounting groove 33.
As another embodiment, instead of providing the flange 34 at the top of the first mounting groove 32, a baffle may be provided at the top of the first mounting groove 32 and/or the second mounting groove 33.
