[0041] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0042] like Figures 1 to 9 The image shows a transformer-rectifier device 100 according to an embodiment of this utility model. (Reference) Figure 1 The transformer-rectifier device 100 includes a transformer 110, a rectifier assembly 120, and a mounting frame 130. The mounting frame 130 forms an installation space, and the transformer 110 and the rectifier assembly 120 are disposed within the installation space. Furthermore, the transformer 110 and the rectifier assembly 120 are spaced apart along the length direction D1 of the mounting frame 130.

[0043] Mounting bracket 130 includes a top plate 131, a bottom plate 132, side plates 133, and end plates 134. The top plate 131 and bottom plate 132 are spaced apart along the height direction D3 of the mounting bracket 130. The side plates 133 and end plates 134 are respectively supported and connected between the top plate 131 and the bottom plate 132 to form an installation space. The end plates 134 are detachably connected to the top plate 131 and the bottom plate 132, as are the side plates 133. This detachable connection reduces the manufacturing difficulty of the mounting bracket 130 and facilitates flexible installation and maintenance of wiring and components within the installation space.

[0044] refer to Figure 1 , Figure 2 and Figures 6 to 9 In this embodiment, the top plate 131, bottom plate 132, side plate 133 and end plate 134 are detachably fixedly connected by threaded connectors.

[0045] In this embodiment, the base plate 132 has a notch 143 at the connection point with the side plate 133 and the end plate 134. A first connecting hole 141 is provided on the side of the base plate 132, and the first connecting hole 141 is located at the notch 143. The two sides of the notch 143 are protrusions, and the base plate 132 has a second connecting hole 142 at the protrusions. The second connecting hole 142 extends along the thickness direction of the base plate 132.

[0046] The lower ends of the side plate 133 and end plate 134 are designed to match the base plate 132. A threaded connector secures the base plate 132 and the side plate 133 (end plate 134) at the notch 143 of the base plate 132 via a first connecting hole 141. The threaded connector can also secure the transformer rectifier 100 and other external equipment via a second connecting hole 142.

[0047] Preferably, when the side plate 133 and the end plate 134 are connected to the base plate 132, the second connecting hole 142 is located directly below or outside the side plate 133 and the end plate 134, so as to avoid affecting the equipment and wiring in the installation space.

[0048] The transformer 110 is detachably connected to the base plate 132 and the top plate 131. The end plate 134 is located outside the transformer 110, providing protection for the transformer 110. Along the length direction D1, the side plate 133 and the end plate 134 are spaced apart; the gap between the end plate 134 and the side plate 133 serves as a heat dissipation channel and facilitates wiring connections between the transformer 110 and the rectifier assembly 120. Along the width direction D2 of the mounting bracket 130, the two side plates 133 are positioned opposite each other, and the rectifier assembly 120 is detachably mounted to the side plate 133.

[0049] refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8 In this embodiment, the transformer 110 includes a magnetic core 111 and a coil sleeved around the magnetic core 111. The coil includes a cylindrical insulating frame 112 and a winding 113 wound around the insulating frame 112, with the insulating frame 112 sleeved around the magnetic core 111. To facilitate fixing the transformer 110, positioning grooves 144 are respectively provided on the top plate 131 and the bottom plate 132 (see...). Figure 6 and Figure 8 The magnetic core 111 is installed in the positioning slot 144.

[0050] In addition, the top plate 131 and the bottom plate 132 are respectively provided with connecting holes at the positioning groove 144. After the transformer 110 is installed, the top plate 131 and the bottom plate 132 can be connected by a long screw and nut, thereby achieving reliable installation and fixation of the transformer 110.

[0051] The transformer 110 has a primary side lead-out terminal and a secondary side lead-out terminal. The primary side lead-out terminal of the transformer 110 is used to connect to external equipment, and the secondary side lead-out terminal of the transformer 110 is used to connect to the rectifier assembly 120.

[0052] See Figure 1 and Figure 6 In the illustrated embodiment, the top plate 131 is provided with a first wiring hole 145 and a terminal block 146. The primary side lead-out of the transformer 110 passes through the first wiring hole 145 and connects to the terminal block 146 on the top surface of the top plate 131. By placing the terminal block 146 on the top plate 131, the primary side lead-out of the transformer 110 can be fixed at the top plate 131, facilitating the connection of other external devices.

[0053] Preferably, the first wiring hole 145 is generally T-shaped, and the inner wall of the first wiring hole 145 is smooth. When there are multiple leads, the multiple leads can be arranged along the inner wall of the T-shaped first wiring hole 145 to achieve neat wiring, which is more aesthetically pleasing and facilitates later maintenance.

[0054] In this embodiment, such as Figure 1 As shown, the rectifier assembly 120 includes multiple rectifier boards 121, each rectifier board 121 having a rectifier circuit. For example... Figure 7 As shown, the inner wall of the side plate 133 is provided with a slot 148 for connecting the rectifier plate 121. Specifically, the slot 148 extends along the length direction D1 and is spaced apart along the height direction D3.

[0055] In other words, the rectifier board 121 is plugged in using two opposing side plates 133 and slots 148 on the inner surface of each side plate 133. Preferably, the opening of the slot 148 faces away from the transformer 110. That is, the rectifier board 121 is inserted into the slot 148 from the end opposite to the end plate 134 along the length direction D1. Multiple rectifier boards 121 are spaced apart to facilitate wiring and heat dissipation.

[0056] To facilitate heat dissipation and the connection wiring between the transformer 110 and the rectifier assembly 120, a second wiring hole 147 is provided in the middle of the side plate 133. The secondary side lead-out of the transformer 110 can be connected to the rectifier assembly 120 through the second wiring hole 147.

[0057] See Figure 1 , Figure 2 and Figure 7 The second wiring hole 147 is located in the middle of the side plate 133, which does not affect the connection between the side plate 133 and the top plate 131 and the bottom plate 132, thus ensuring the stability of the mounting bracket 130.

[0058] Mounting bracket 130 also includes a support member. The support member is connected to at least one of the two side plates 133 and is positioned below slot 148 to support rectifier plate 121.

[0059] like Figure 1 As shown, in this embodiment, the support member is constructed as a support strip 149 extending along the width direction D2, and the support strip 149 is detachably connected to the side plate 133. See also Figure 7 A connection hole for connecting the support bar 149 is provided below the slot 148.

[0060] See Figures 1 to 5 The mounting bracket 130 also includes positioning plates 150, which are fixedly connected to the end plate 134. The two positioning plates 150 are spaced apart along the height direction D3. The two positioning plates 150 are located at the top and bottom of the coil, respectively, to restrict movement of the coil along the height direction D3 (e.g., ...). Figure 2 and Figure 5 (As shown in the diagram). The positioning plate 150 can fix the relative position of the coil and the end plate, preventing the coil from colliding with the magnetic core 111 during the use of the transformer rectifier 100 and causing damage to the magnetic core 111.

[0061] refer to Figure 3 and Figure 4The positioning plate 150 is rectangular in shape, and has a through hole 151 in its center to allow the magnetic core 111 to pass through. During installation, the positioning plate 150 is fitted over the magnetic core 111 and fixed to the end plate 134. It is understood that the through hole 151 restricts the coil from passing through. Furthermore, the positioning plate 150 also includes a limiting part 152, which, when the positioning plate 150 is connected to the end plate 134, extends at least partially into the insulating frame 112. In this embodiment, the limiting part 152 is located near the through hole 151, and is configured to conform to the inner surface of the insulating frame 112 when the positioning plate 150 is connected to the end plate 134. Thus, the limiting part 152 enables radial positioning of the coil, preventing radial movement of the coil relative to the magnetic core 111 and better protecting the magnetic core 111 and the coil.

[0062] The positioning plate 150 is detachably fixed to the end plate 134. (Reference) Figure 2 , Figure 3 and Figure 9 The positioning plate 150 has connecting holes on its side, and the end plate 134 also has corresponding connecting holes. The positioning plate 150 and the end plate 134 are installed and fixed by threaded fasteners. To facilitate the installation and heat dissipation of the transformer 110, a through hole 151 is provided in the middle of the end plate 134.
