Description

Technical Field

[0001] The present invention relates to the technical field of micro transformers, in particular to a high-power micro electronic transformer. Background Art

[0002] A microelectronic transformer is a small, compact transformer primarily used for voltage conversion, power adaptation, signal isolation, and electromagnetic energy transmission. It achieves voltage conversion through electromagnetic induction, but its size and structural design better suit the space requirements of modern small electronic devices. A high-power microelectronic transformer, on the other hand, is a miniaturized transformer designed specifically for high-power applications, capable of handling greater power within a smaller footprint. This transformer not only maintains the small size and light weight of a microelectronic transformer but also meets high-power requirements. It is widely used in electronic products requiring high power and compact design.

[0003] However, existing high-power micro-electronic transformers have the following shortcomings:

[0004] 1) In existing technologies, micro electronic transformers follow industry-standard pin spacing designs to ensure compatibility with contacts on other components or circuit boards. The pin spacing cannot be adjusted, and the hole spacing, layout, and size of the circuit board restrict the arrangement of the pins, resulting in poor compatibility between the transformer and other components or circuit boards. Furthermore, the pin spacing cannot be adjusted to accommodate different placement spaces, resulting in inefficient use of space and poor space utilization.

[0005] 2) Existing micro-electronic transformers typically use cylindrical pins, which have limited contact area with the circuit board. During high-power transmission, heat easily accumulates on the pin surface, generating thermal stress and poor heat dissipation. Flat pins, which have better heat dissipation, have poor fracture resistance. When the pins break or deform, heat cannot be effectively conducted, affecting the stable transmission of the transformer.

[0006] 3) In the prior art, the entire micro-electronic transformer is fixed by bolts. When the transformer needs to be disassembled for maintenance, tools are required. The operation is cumbersome and time-consuming, making it inconvenient to maintain the transformer.

[0007] Therefore, we propose a high-power micro electronic transformer to solve the above problems. Summary of the Invention

[0008] The present invention aims to provide a high-power micro-electronic transformer that achieves better compatibility and space utilization.

Then, the number of pins can be reduced or increased according to the size of the space, and the pins are inserted into the placement groove. Then, the return spring is reset, and the clamping block drives multiple groups of pins to move synchronously, thereby achieving the purpose of simultaneously limiting the position of multiple groups of pins. Pins of different sizes can be replaced as needed to adapt to different placement spaces, thereby improving the space utilization of the transformer.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] Please see the attached Figure 1 -Attached Figure 7 As shown, the present invention provides a technical solution: a high-power micro electronic transformer, including a main body 1, the main body 1 includes a lower magnetic core 101, an upper magnetic core 102 and a base 103 are respectively installed on the top and inner side of the lower magnetic core 101, a pin 104 and an adjustment mechanism 2 are provided on one side of the outer surface of the base 103, a heat dissipation mechanism 3 is provided on the outer surface of the pin 104, and a fixing mechanism 4 is provided on the surface of the upper magnetic core 102 and the lower magnetic core 101.

[0033] Example 1, according to Figure 1-5As shown, a support plate 105 is provided at the top of the base 103, a frame 107 is fixedly installed at the top of the support plate 105, and an enameled wire 106 is installed on the outer surface of the frame 107. The adjustment mechanism 2 includes a placement groove 201, which is opened on one side of the outer surface of the base 103, and a groove is opened at one end of the outer surface of the pin 104, and the pin 104 is inserted into the inner side of the placement groove 201. A storage groove 202 is opened on one side of the outer surface of the base 103, and a connecting rod 203 is slidably connected to the inner side of the storage groove 202. A clamping block 204 is fixedly installed on the top of the connecting rod 203, and a groove is opened on the inner side of the placement groove 201. There is a movable groove 205, and the placement groove 201 is symmetrically distributed on one side of the outer surface of the base 103, and sliders are fixedly installed at both ends of the inner side of the placement groove 201. The clamping block 204 is slidably connected to the surface of the slider and the inner side of the movable groove 205. A return spring 206 is fixedly installed on one side of the outer surface of the clamping block 204, and one end of the outer surface of the return spring 206 is fixedly installed on one side of the inner surface of the placement groove 201. A fixing hole 207 is provided on one side of the outer surface of the connecting rod 203 and the base 103. A threaded rod 208 is rotatably connected to the inner side of the fixing hole 207, and a turning handle 209 is fixedly installed on one end of the outer surface of the threaded rod 208.

[0034] The effect achieved by the entire embodiment 1 is: achieving better compatibility and space utilization, firstly, the threaded rod 208 is driven away from the fixing hole 207 by turning the handle 209, and then the connecting rod 203 is moved to a suitable position, so that the connecting rod 203 drives the clamping block 204 to move, and the moving path of the clamping block 204 is limited by the moving groove 205 and the slider, thereby ensuring the stability of the movement of the clamping block 204, and then the clamping block 204 drives the return spring 206 to expand and contract inside the placement groove 201, and then the number of pins 104 can be reduced or increased according to the size of the space, and the pins 104 can be plugged in.

After the pins 104 are adjusted to the appropriate position, the threaded rod 208 can be driven by the turning handle 209 to be inserted into the fixing hole 207, thereby completing the limitation of the connecting rod 203, providing convenience for the adjustment of the spacing between the pins 104, and improving the compatibility of the transformer with other components.

[0035] Example 2, according to Figure 2 and Figure 6As shown, the heat dissipation mechanism 3 includes honeycomb holes 301, which are symmetrically distributed on the outer surface of the pin 104. The pin 104 adopts an internal hollow design, and a longitudinal reinforcement block 302 and a transverse reinforcement block 303 are fixedly installed on the inner side of the pin 104. The curved part inside the pin 104 is fixedly installed with a reinforcing rib 304 and a reinforcing ring 305. The reinforcing rib 304 and the reinforcing ring 305 are fixedly installed on the surface of the longitudinal reinforcement block 302 and the transverse reinforcement block 303, and the reinforcing ring 305 is symmetrically distributed around the reinforcing rib 304.

[0036] The effect achieved by the entire embodiment 2 is: achieving more effective heat dissipation and anti-fracture properties. First, through the design of hollowing out the pin 104 and opening the honeycomb hole 301 on the surface, heat is conducted more quickly through the cavity inside the pin 104, and air flow is promoted, thereby reducing heat accumulation on the surface and improving the heat dissipation of the pin 104. At the same time, the longitudinal reinforcement block 302 and the transverse reinforcement block 303 are used to improve the anti-fracture property of the pin 104, and the reinforcement rib 304 and the reinforcement ring 305 provided at the bent part of the pin 104 are used to reduce force concentration. Under the action of external force, the pin 104 can be made to disperse stress in different directions, thereby preventing the pin 104 from breaking due to local bending or excessive stretching. While ensuring the heat dissipation of the pin 104, its anti-fracture property is improved, so that the pin 104 reaches the best balance between heat dissipation and anti-fracture property, thereby improving the stability of transformer transmission.

[0037] Example 3, according to Figure 2 and Figure 7 As shown, the fixing mechanism 4 includes a card slot 401, which is opened at the top of the base 103 and the inner bottom of the lower magnetic core 101, and the bottom of the upper magnetic core 102 is slidably connected to the inner side of the card slot 401. The top of the lower magnetic core 101 is provided with a square groove 402 and a slot, and the inner side of the square groove 402 is slidably connected to a support frame 403, and the support frame 403 is fixedly installed at the bottom end of the upper magnetic core 102. The bottom end of the upper magnetic core 102 is fixedly installed with an insert block 404, and the insert block 404 is slidably connected to the inner side of the slot, and the lower magnetic core 101 and the square groove 402 are fixedly installed. Both sides of the surface are rotatably connected with rotating rods 405, both sides of the outer surface of the upper magnetic core 102 are provided with U-shaped grooves, the rotating rod 405 is arranged on the inner side of the U-shaped groove, and both sides of the inner and outer surfaces of the lower magnetic core 101 are provided with limiting grooves, and both sides of the inner and outer surfaces of the upper magnetic core 102 are slidably connected to the inner side of the limiting grooves, a knob 406 is fixedly installed on one end of the outer surface of the rotating rod 405, and a gear 407 is fixedly installed on the outer surface of the rotating rod 405, and a rack 408 is fixedly installed on one side of the inner surface of the support frame 403, and the rack 408 is meshed with the gear 407.

[0038] The effect achieved by the entire embodiment 3 is: faster maintenance and wider adaptability are achieved. First, the knob 406 is used to drive the rotating rod 405 to rotate, so that the rotating rod 405 drives the gear 407 to rotate, and then the gear 407 drives the rack 408 and the support frame 403 to move up and down, and the support frame 403 drives the upper magnetic core 102 to move, and then the upper magnetic core 102 drives the plug 404 to move, and the plug 404, the slot and the limit groove are used to limit the moving path of the upper magnetic core 102, and then the upper magnetic core 102 can be moved. The magnetic core 102 is moved to a suitable position, and the skeleton 107 and the base 103 are removed for maintenance, and then the maintained skeleton 107 and the base 103 are put back to their original positions. Conversely, the upper magnetic core 102 can be moved by the knob 406 so that the upper magnetic core 102 is clamped on top of the skeleton 107, and the bottom of the upper magnetic core 102 is clamped with the slot 401. The base 103 can be limited by the upper magnetic core 102, which provides convenience for the maintenance of the transformer. At the same time, different models of skeletons 107 can be placed by adjusting the position of the upper magnetic core 102.

[0039] The working principle of the whole device is as follows: when the spacing of the pins 104 of the transformer needs to be adjusted, the threaded rod 208 is first driven away from the fixing hole 207 by turning the handle 209, and then the connecting rod 203 is moved to a suitable position, so that the connecting rod 203 drives the clamping block 204 to move, and the moving path of the clamping block 204 is limited by the moving groove 205 and the slider, thereby ensuring the stability of the movement of the clamping block 204, and then the clamping block 204 drives the return spring 206 to expand and contract inside the placement groove 201, and then the number of pins 104 can be reduced or increased according to the size of the space. Since the concave part of the groove is consistent with the height of the slider, the groove of the pin 104 can be inserted into the placement groove 201, and then the return spring 206 is used to move the pin 104. The reset causes the clamping block 204 to drive the multiple groups of pins 104 to move synchronously, thereby achieving the purpose of limiting the multiple groups of pins 104 at the same time, and the pins 104 of different sizes can be replaced as needed to adapt to different placement spaces, thereby improving the space utilization rate of the transformer. After the pins 104 are adjusted to the appropriate position, the threaded rod 208 can be driven by the turning handle 209 to be inserted into the fixing hole 207, thereby completing the limiting of the connecting rod 203, providing convenience for the adjustment of the spacing between the pins 104, and improving the compatibility of the transformer with other components. In the process of using the transformer, the design of hollowing out the pins 104 and opening the honeycomb holes 301 on the surface can make the heat conduction faster through the cavity inside the pins 104, and promote air Flow, reduce heat accumulation on the surface, improve the heat dissipation of pin 104, at the same time, the longitudinal reinforcement block 302 and the transverse reinforcement block 303 are used to improve the anti-fracture property of pin 104, and the reinforcement rib 304 and the reinforcement ring 305 set at the bent part of pin 104 are used to reduce the force concentration. Under the action of external force, the stress of pin 104 can be dispersed in different directions, thereby preventing the pin 104 from breaking due to local bending or excessive stretching. While ensuring the heat dissipation of pin 104, its anti-fracture property is improved, so that pin 104 achieves the best balance between heat dissipation and anti-fracture property, thereby improving the stability of transformer transmission. During the maintenance of the transformer, the knob 406 is first used to drive the rotating rod 405 to rotate, so that the rotating rod 405 drives the gear 407 rotates, and then the gear 407 drives the rack 408 and the support frame 403 to move up and down, and the support frame 403 drives the upper magnetic core 102 to move, and then the upper magnetic core 102 drives the plug block 404 to move, and the moving path of the upper magnetic core 102 is limited by the plug block 404, the slot and the limit groove, and then the upper magnetic core 102 can be moved to a suitable position, and the skeleton 107 and the base 103 are removed for maintenance, and then the maintained skeleton 107 and the base 103 are put back in place, and then the knob 406 drives the gear 407 to rotate, so that the gear 407 drives the rack 408 and the support frame 403 to move, and then the upper magnetic core 102 is driven to move by the support frame 403.The upper magnetic core 102 is clamped on the top of the frame 107, and the bottom of the upper magnetic core 102 is clamped with the clamping slot 401. The upper magnetic core 102 can limit the base 103, which provides convenience for transformer maintenance. At the same time, different types of frames 107 can be placed by adjusting the position of the upper magnetic core 102.
