[0003] To sum up: although the transformer in the above scheme solves the problem of transformer heat dissipation, the transformer in the above scheme is installed and connected to the circuit board through pins.

In addition, since the ventilation plate of the transformer in the above-mentioned scheme is installed inside the installation groove, the ventilation plate and the circuit board are installed too close to each other after the transformer is installed, resulting in the inability to achieve ventilation and conveying effects. At the same time, the transformer in the above-mentioned scheme is often covered with dust after long-term operation.

[0005] To achieve the above object, the present invention provides the following technical solution: a main power transformer with an internal heat dissipation duct, comprising a connection seat structure, on which a transformer structure is mounted;

[0009] Preferably, the transformer structure includes an insulating seat with a slot, and a transformer body is fixedly installed on the top of the insulating seat, and a hollow frame connected to the transformer body is fixedly installed on the bottom of the insulating seat, and a heat dissipation fan is fixedly installed inside the hollow frame.

[0010] By adopting the above technical solution, the heat dissipation fan is provided to assist in heat dissipation.

[0011] Preferably, a filter screen is fixedly mounted on the surface of the hollow frame, a connecting column is fixed on the bottom of the insulating seat, and a conductive contact cylinder that is in electrical contact with the conductive cylinder is fixed on the surface of the connecting column.

[0012] By adopting the above technical solution, the connection column is provided to achieve a fixed installation connection.

[0013] Preferably, a through frame of a fixing slot is mounted on the card slot in a matching manner, and another filter screen is fixed to the through frame through the inside of the fixing slot, and through holes are penetrated through the through frame to facilitate the extension of the transformer body parts.

[0023] Preferably, four filter screen plates are provided, and the filter screen plates are installed equidistantly with respect to the surface of the hollow frame.

[0024] By adopting the above technical solution, the filter screen is provided to achieve interception and filtration.

[0025] Compared with the prior art, the invention has the following beneficial effects: the main power transformer with internal heat dissipation duct,

[0026] (1) In this case, the transformer structure is provided with: a connecting column and a conductive contact cylinder, thereby solving the problem in the above scheme that the transformer is installed and connected to the circuit board through pins. However, when the transformer is installed and connected to the circuit board through pins, it will cause the transformer to be unable to be quickly disassembled, repaired or replaced during later maintenance or replacement. When the transformer body needs to be installed and connected to the circuit board, the operator slides and matches the transformer body with the connecting cylinder through the connecting column and the conductive contact cylinder. After the connecting cylinder and the connecting column are slid and matched, the conductive cylinder and the conductive contact cylinder are electrically connected. When the above two are electrically connected, it is convenient for the subsequent transformer body to be quickly installed and disassembled;

[0027] (2) The hollow frame and the filter screen plate are arranged in the transformer structure, so as to solve the problem that the ventilation plate of the transformer in the above scheme is installed inside the installation slot, and the ventilation plate and the circuit board are installed too close to each other after the transformer is installed, so that the ventilation and conveying effect cannot be achieved. When the transformer body is slid and installed, the heat dissipation fan transmits the external airflow through the filter screen plates around the hollow frame to the inside of the transformer body during the operation of the transformer body, so as to assist the heat dissipation of the transformer body during the operation;

[0028] (3) The transformer structure is provided with: a pass frame and a filter screen plate, so as to solve the problem that the transformer in the above scheme is often covered with dust after long-term operation. When the transformer body is installed and works for a long time, external dust will enter the equipment through the heat dissipation holes of the equipment. When the external dust enters the equipment, the external dust is intercepted and processed by the filter screen plate. When the dust entering from the outside is intercepted by the filter screen plate and the pass frame, the dust is prevented from adhering to the surface of the transformer body;

[0029] (4) By providing a damping shock absorber in the connecting seat structure, the problem that the vibration generated during the operation of the transformer in the above solution cannot be buffered is solved. When the vibration generated during the operation of the transformer body is transmitted to the insulating seat, the insulating seat transmits the vibration to the damping shock absorber. At this time, the damping shock absorber buffers and reduces the vibration generated during the operation of the transformer body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-6 The present invention provides a technical solution: a main power transformer with an internal heat dissipation duct, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a connecting seat structure 1, which includes a through-hole plate 101 with a damping shock absorber 102 fixed on the top, and a connecting tube 103 is fixed through the through-hole plate 101, and a group of connecting tubes 103 are provided, and concentric conductive tubes 104 are provided inside the connecting tubes 103. When the above-mentioned parts are provided in one group, it not only reflects the inner and outer side installation properties of the above-mentioned parts, but also reflects the contact conductivity of the above-mentioned parts installation settings. When the above-mentioned parts are provided in one group, it also reflects the practicality and overall aesthetics of the above-mentioned parts installation settings. When the concentric conductive tubes 104 are provided inside the connecting tube 103, it effectively facilitates the sliding matching installation of the conductive contact tube 207 and the connecting column 206. At the same time, the conductive tube 104 is fixedly installed inside the connecting tube 103, and a pin 105 connected to the circuit board is welded and fixed at the bottom of the connecting tube 103.

[0039] In the above solution, the operator can use an electric soldering iron to fix the through-hole board 101 on the circuit board through the pins 105 .

[0040] like Figure 4 , Figure 5 and Figure 6 As shown, a transformer structure 2 is installed on the connecting seat structure 1, and the transformer structure 2 includes an insulating seat 201 with a slot 202, and the slot 202 is opened in a "square" shape as a whole. When the overall shape is opened in a "square" as a result, it not only reflects the card-matching installation of the above structure and the through frame 208, but also facilitates the rapid installation and disassembly and separation effect of the through frame 208. When the overall shape of the above structure is opened in a "square", the practicality, axial symmetry and overall appearance of the above structure are reflected at the same time. A transformer body 203 is fixedly installed above the insulating seat 201, and a hollow frame 204 connected to the transformer body 203 is fixedly installed at the bottom of the insulating seat 201, and a heat dissipation fan 205 is fixedly installed inside the hollow frame 204, wherein the transformer body 203 and the heat dissipation fan 205 both adopt the component installation setting in the comparative document, and the component installation setting in the comparative document is used to effectively transport the airflow generated during the operation of the heat dissipation fan 205 to the inside of the transformer body 203 for auxiliary heat dissipation treatment.

[0041] In the above scheme, a filter screen plate 2010 is fixedly installed on the surface of the hollow frame 204, and there are 4 filter screen plates 2010, and the filter screen plates 2010 are equidistantly installed on the surface of the hollow frame 204. When the above components are arranged in 4 pieces, not only the equidistant distribution installation of the above components is reflected, but also the four-sided ventilation of the above components is reflected. When the above components are arranged in 4 pieces, the filtering interception of the above component installation is reflected. At the same time, when the filter screen plates 2010 are equidistantly installed on the surface of the hollow frame 204, the situation that only one side of the hollow frame 204 is ventilated is avoided. A connecting column 206 is fixed at the bottom of the insulating seat 201, and the connecting column 2 A conductive contact cylinder 207 that is in electrical contact with the conductive cylinder 104 is fixed on the surface of 06. The conductive contact cylinder 207 and the conductive cylinder 104 are arranged in concentric circles, and both the conductive contact cylinder 207 and the conductive cylinder 104 are arranged in conductive metal materials. By arranging the above-mentioned components in concentric circles, not only the relative wrapping installation property of the above-mentioned components is reflected, but also the relative sliding adjustability of the above-mentioned components is reflected. When the above-mentioned components are arranged in concentric circles, the coaxial and concentric quick matching installation property of the above-mentioned components is reflected. At the same time, when the conductive contact cylinder 207 and the conductive cylinder 104 are both arranged in conductive metal materials, the current transmission effect is effectively achieved.

[0042] Furthermore, in the above scheme, a through frame 208 with a fixed slot is installed on the card slot 202, and another filter screen plate 2010 is fixed to the through frame 208 through the inside of the fixed slot. At the same time, a through hole 209 is opened through the through frame 208 for convenient extension of the parts of the transformer body 203. A group of through holes 209 is opened, and the through holes 209 are symmetrically opened about the upper surface of the through frame 208. When a group of two is opened through the above structure, this set not only reflects the symmetry of the above structure, but also reflects the convenience of the parts through-installation of the above structure. When a group of two is opened through the above structure, the practicality and axial symmetry of the above structure are simultaneously reflected.

[0043] In the above scheme, when the transformer body 203 needs to be installed and connected with the circuit board, the operator slides and connects the transformer body 203 with the connecting tube 103 through the connecting column 206 and the conductive contact tube 207. After the connecting tube 103 is slid and connected with the connecting column 206, the conductive tube 104 is electrically connected with the conductive contact tube 207. When the above two are electrically contacted and connected, it is convenient for the subsequent transformer body 203 to be quickly installed and disassembled. After the transformer body 203 is installed, the operator holds the through frame 208 and engages with the card slot 202 to conveniently wrap and protect the transformer body 203.
