Description

Technical Field

[0001] The utility model relates to the technical field of audio transformers, in particular to an audio transformer that can be installed diversely. Background Art

[0002] Audio transformers play the roles of coupling, isolation, and impedance matching in circuits. The working frequency range is generally from 10 to 20,000 Hz, and they are mostly used in audio systems and broadcast systems. When an audio transformer inputs a signal, it usually needs to be connected to a connector with a wire, and the wire plays a transmission role between the connector and the transformer.

[0003] There are two installation methods for audio transformers during use. The first installation method is to directly fixedly connect the audio transformer to the PCB board. The connection method is to connect the pins on the audio transformer to the PCB board by soldering. The second method is to set a housing outside the audio transformer, fix it on the mounting plate (the side wall of the chassis or other support plates) through fasteners, and then connect it to the PCB board through a plug connector. As a result, the audio transformer with the first installation method cannot be installed using the second installation method, and similarly, the audio transformer with the second installation method cannot be installed using the first installation method.

When the audio transformer is fixedly installed on the side wall of the chassis or other support plates.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] As Figures 1 - 3 shown, the audio transformer of the present invention has a body 01. The body 01 includes a bobbin and an iron core inserted into the bobbin. A primary coil and a secondary coil are wound on the outer surface of the bobbin. Two connecting frames 02 with the same structure and opposite mounting directions are provided on the body 01. The two connecting frames 02 can be provided on the bobbin or on the iron core, which is not limited here. Preferably, the two connecting frames 02 are provided on the iron core. Both ends of the connecting frame 02 are respectively connected with a sealing plate 03 and a connecting plate 04 through fasteners. Pins 05 electrically connected to the body 01 are provided on the connecting plate 04. A housing 06 is connected to the outer surface of the connecting frame 02 through fasteners. The above-mentioned sealing plate 03, connecting plate 04, connecting frame 02 and body 01 are all located inside the housing 06. At the same time, epoxy resin is filled in the gap between the body 01 and the housing 06.

[0020] During installation, the audio transformer is fixed by passing fasteners through an external mounting plate and connecting to the connecting frame 02 inside the housing, and then the pins are connected to the PCB board by welding. Thus, it is avoided that the audio transformer shakes during transportation or under the action of gravity, and further, the phenomenon that the pins 05 on the body 01 are loosened from the connection points on the PCB board is avoided.

[0021] When the mounting plate is a PCB board, through holes are provided on the PCB board. The fasteners on the connecting plate 04 are removed, and the pins 05 on the connecting plate 04 are inserted through the through holes on the PCB board. Then, longer fasteners are sequentially passed through the through holes on the PCB board and the connecting plate 04 to be fixedly connected to the connecting frame 02 inside the housing 06 to fix the audio transformer to the PCB board, thus avoiding that the audio transformer shakes during transportation or under the action of gravity, and further, the phenomenon that the pins 05 on the body 01 are loosened from the connection points on the PCB board is avoided. After the audio transformer is fixed, the pins 05 are welded to the PCB board by welding.

The fasteners on one side of the housing 06 are disassembled, and then longer fasteners are sequentially passed through the through holes on the mounting plate and the housing 06 and the connecting frame 02 inside the housing 06 for fixed connection. Thus, the body 01 is installed on the mounting plate, preventing the audio transformer from shaking during transportation or under the action of gravity, and further avoiding the loosening of the pins 05 on the body 01 and the connection points on the PCB board. After the audio transformer is fixed, the pins 05 are welded to the PCB board by welding.

[0023] The connecting frame 02 includes a support rod 07 and a fixing rod 08 arranged in parallel. Through holes are respectively provided at both ends of the fixing rod 08, and a connecting rod 09 is arranged in each through hole. The connecting rod 09 is preferably a fastener. One end of the connecting rod 09 passes through the through hole on the fixing rod 08 and is threadedly connected to the threaded hole on the support rod 07. Therefore, a mounting hole 10 is provided between the fixing rod 08 and the support rod 07. The iron core on the body 01 is fixed in the mounting hole 10. Two or more connecting holes 11 are provided on one side of the fixing rod 08, and the connecting holes 11 and the connecting rod 09 are arranged on both sides of the fixing rod 08. Fixing holes 12 extending along the axial direction of the fixing rod 08 are respectively provided at both ends of the fixing rod 08. The above fixing holes 12 and connecting holes 11 are both threaded holes. During use, the body 01 is placed in the mounting hole 10, and then the body 01 is fixed by the connecting rod 09, combining the body 01 and the two connecting frames 02 into a whole.

Notches 18 are provided between both ends of the fixing plate 17 and the second connecting plate 16. The connecting plate 04 and the sealing plate 03 are both located in the notches 18 and respectively abut against both ends of the fixing plate 17. The height of the notch 18 is equal to the thickness of the connecting plate 04. The length of the fixing plate 17 is the same as the length of the support rod 07. Through holes 19 communicating with the connecting holes 11 are provided on both the fixing plate 17 and the first connecting plate 15. During the assembly process, the first connecting plate 15 on the first outer shell 13 is abutted against the fixing plate 17 on the second outer shell 14.
