With the extensive application of electronic components in power plant control, monitoring, and automatic circuits, the application of small transformers is becoming increasingly widespread.

[0003] When the existing high-frequency small transformers are in use, most of them do not have a heat dissipation structure. As a result, after the transformer is installed and operates for a long time, the temperature of the copper coil inside the transformer will increase, and the high temperature will spread to the shell of the transformer, causing damage to the components of the device, and often requiring the transformer to be replaced, which is rather troublesome.

[0006] Further, working cavities are horizontally formed both inside and outside the mounting base, and the bottom end of the conductive rod extends into the inner cavity of the working cavity.

[0007] Further, a conductive seat is vertically and fixedly installed on the outer side of the inner cavity of the working cavity, and a moving seat is vertically and slidably arranged in the inner cavity of the moving groove.

[0008] Further, one end of the moving seat is horizontally and fixedly installed with a conductive plate extending into the inner cavity of the working cavity, and the end of the conductive plate away from the moving seat is in contact with the conductive seat.

[0009] Further, a fixing block extending outside the mounting base is fixedly installed on the front surface of the moving seat, and a sliding block is vertically and fixedly installed on the front surface of the fixing block.

[0010] Further, a connecting hole is horizontally formed in a concave shape on the front surface of the mounting base between the two moving grooves, and a front heat dissipation plate is detachably arranged inside the connecting hole.

[0011] Further, bolts extending into the inner cavity of the moving groove are horizontally and rotatably arranged at both ends of the front heat dissipation plate, and threaded holes adapted to the bolts are formed in the inner wall of the moving groove.

[0012] Further, a groove is horizontally formed in a concave shape on the upper surface of the connecting cover, and a lifting handle is fixedly installed inside the groove.

[0013] Further, a lower heat dissipation plate is detachably arranged on the outer side of the fixing seat, and a connecting sleeve extending into the inner cavity of the mounting groove is horizontally and fixedly installed at the top of the inner wall of the lower heat dissipation plate.

After the metal pins are welded to the circuit board, the transformer body can be replaced and repaired.

[0018] (3) The high-frequency small transformer with an external heat dissipation structure of the present invention has a lower heat dissipation plate. Before the connection cover and the fixing seat are installed, the connection sleeve on the top of the lower heat dissipation plate is inserted into the inner cavity of the installation groove, and then the installation rod is inserted into the inner cavity of the installation groove, so that the installation rod passes through the connection sleeve to fix the connection sleeve, and then the bottom of the lower heat dissipation plate and the fixing seat are fixed by bolts, so that the lower heat dissipation plate can be fixed to the heat conductive block, and then the heat can be dissipated, so that the heat conductive block can cool the heat conductive seat faster, thereby reducing the temperature of the transformer body, so that the heat dissipation area of ​​the device is further increased.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figures 1-6 , the present invention provides a technical solution: a high-frequency small transformer with an external heat dissipation structure, including a transformer body 1, a heat conduction seat 2, a mounting seat 5, and a connection cover 13; a connecting plate 4 is horizontally arranged at the bottom of the transformer body 1, the mounting seat 5 is detachably horizontally arranged at the bottom of the connecting plate 4, heat conduction seats 2 are vertically arranged on both sides of the upper surface of the connecting plate 4 and located on both sides of the transformer body 1, and a connection cover 13 is detachably arranged at the top of the transformer body 1; heat conduction blocks 3 are vertically and fixedly installed on both sides of the upper surface of the mounting seat 5, metal pin feet 6 are vertically and fixedly installed on the lower surface of the mounting seat 5, and a plurality of metal pin feet 6 are arranged along the length direction of the mounting seat 5, a fixing seat 24 bolt-connected to the connection cover 13 is fixedly installed at the top of the heat conduction block 3, and an installation groove 20 is vertically opened inwards and recessed at the top of the fixing seat 24.

[0028] Installation rods 21 extending into the inner cavity of the installation groove 20 are vertically and fixedly installed on both sides of the bottom of the connection cover 13, and an upper heat dissipation plate 15 is detachably arranged at the top of the connection cover 13.

[0029] Through the installation rod 21, when the connecting plate 4 is in contact with the mounting seat 5, then the installation rod 21 at the bottom of the connection cover 13 is inserted into the installation groove 20 inside the fixing seat 24, and then the fixing seat 24 and the connection cover 13 are bolt-fixed to fix the connecting plate 4 and the mounting seat 5.

[0030] Fixing rods 18 are fixedly installed on the lower surface of the upper heat dissipation plate 15, and a plurality of fixing rods 18 are arranged along the length direction of the upper heat dissipation plate 15.

[0031] When the heat generated by the transformer body 1 is introduced into the connection cover 13 through the upper heat dissipation plate 15, the upper heat dissipation plate 15 can dissipate the heat of the connection cover 13.

[0032] A fixing groove 17 is vertically opened inwards and recessed on the upper surface of the connection cover 13, a rubber ring 19 is arranged on the surface of the fixing rod 18, and a clamping groove adapted to the rubber ring 19 is opened on the inner wall of the fixing groove 17; conductive rods 12 are vertically arranged on both sides of the lower surface of the connecting plate 4, and moving grooves 7 are horizontally opened on both sides of the inner cavity of the mounting seat 5.

[0033] Due to the elasticity of the rubber ring 19, the fixing rod 18 drives the rubber ring 19 to move inside the fixing groove 17. The rubber ring 19 can be squeezed by the fixing groove 17 to contract, and then it can resume its original shape when it reaches the clamping groove, so that the rubber ring 19 can be snapped into the clamping groove to increase the friction between the fixing rod 18 and the fixing groove 17, thereby fixing the fixing rod 18 and the fixing groove 17, and installing the upper heat dissipation plate 15.

[0034] Through the fixing rod 18, when the upper heat dissipation plate 15 is installed on the connection cover 13, the fixing rod 18 can be inserted into the fixing groove 17 for auxiliary positioning. Subsequently, the rubber ring 19 is snapped into the clamping groove, so that the upper heat dissipation plate 15 and the connection cover 13 can be detachably connected.

[0035] A working cavity 11 is horizontally opened both inside and outside the mounting seat 5. The bottom end of the conductive rod 12 extends into the inner cavity of the working cavity 11.

The end of the conductive plate 9 away from the moving seat 28 is in contact with the conductive seat 10.

[0036] Through the conductive plate 9, when the transformer main body 1 fails, the slider 27 can be slid to make the conductive plate 9 separate from the conductive seat 10, so that the transformer main body 1 is powered off. Subsequently, the connection between the connection cover 13 and the fixed seat 24 is released, and the transformer main body 1 can be disassembled separately. After the metal pin 6 is welded to the circuit board, the transformer main body 1 can be replaced and repaired.

[0037] When the metal pin 6 is welded to the circuit of the circuit board, the current can enter the inside of the conductive seat 10 through the metal pin 6, and then be introduced into the inside of the conductive rod 12 through the conductive plate 9, and then the transformer main body 1 performs voltage transformation.

[0038] A fixing block 26 extending outside the mounting seat 5 is fixedly installed on the front surface of the moving seat 28. A slider 27 is vertically and fixedly installed on the front surface of the fixing block 26.

[0039] By setting the slider 27, it is convenient for the staff to manually slide the fixing block 26 to move, so that the moving seat 28 drives the conductive plate 9 to be inserted into the conductive seat 10.

[0040] A connection hole 8 is horizontally opened on the front surface of the mounting seat 5 and recessed inward between the two moving grooves 7. A front heat dissipation plate 16 is detachably arranged inside the connection hole 8. Both ends of the front heat dissipation plate 16 are horizontally and rotatably provided with bolts extending into the inner cavity of the moving groove 7. Threaded holes adapted to the bolts are opened on the inner wall of the moving groove 7.

[0041] By setting the front heat dissipation plate 16, when the front heat dissipation plate 16 is installed on the surface of the mounting seat 5, it can limit the slider 27 while increasing the heat dissipation effect.

[0042] The upper surface of the connection cover 13 is transversely provided with a concave groove 14, and a lifting handle is fixedly installed inside the concave groove 14.

[0043] Through the lifting handle, it is convenient for the staff to take the connection cover 13.

[0044] The lower heat dissipation plate 23 is detachably arranged on the outside of the fixed seat 24. The top of the inner wall of the lower heat dissipation plate 23 is transversely and fixedly installed with a connection sleeve 22 extending into the inner cavity of the installation groove 20. A connection groove adapted to the installation rod 21 is vertically penetrated inside the connection sleeve 22. Heat dissipation holes 25 are transversely penetrated on both sides inside the connection cover 13. The bottom of the lower heat dissipation plate 23 is fixedly installed with the heat conduction block 3 through bolts.

[0045] Through the lower heat dissipation plate 23, before the connection cover 13 and the fixed seat 24 are installed, the connection sleeve 22 at the top of the lower heat dissipation plate 23 is inserted into the inner cavity of the installation groove 20, and then the installation rod 21 is inserted into the inner cavity of the installation groove 20, so that the installation rod 21 passes through the connection sleeve 22 to fix the connection sleeve 22. Then, through the bolt fixation of the bottom of the lower heat dissipation plate 23 and the fixed seat 24, the lower heat dissipation plate 23 can be fixed in contact with the heat conduction block 3, and then heat dissipation can be carried out.

[0046] Through the disassembly structure of the upper heat dissipation plate 15, the lower heat dissipation plate 23 and the front heat dissipation plate 16, the surface of the transformer body 1 can be externally cooled.

[0047] During installation, insert the conductive rod 12 at the bottom of the connecting plate 4 into the inner cavity of the working cavity 11, and then fit the connection cover 13 to the top of the transformer body 1 while inserting the installation rod 21 into the inner cavity of the installation groove 20, so that the connection cover 13 can limit the transformer body 1 and fix the transformer body 1. Then, fixedly connect the fixed seat 24 and the connection cover 13 through bolts. Then, weld the metal pins 6 to the circuit board.
