Description

Technical Field

[0001] This invention relates to the field of surface mount electronic transformer technology, specifically to a surface mount electronic transformer. Background Technology

[0002] Surface mount electronic transformers are miniaturized electronic components that combine surface mount technology with high-frequency power conversion technology. They are primarily used for voltage conversion and signal isolation in modern electronic devices. Power conversion is achieved through semiconductor switching devices and high-frequency magnetic cores. Their highly integrated structure encapsulates the coil and core in a plastic housing, resulting in a compact size that can be directly soldered onto circuit boards without additional mounting brackets. Unlike traditional power frequency transformers, surface mount electronic transformers employ an "AC-DC-AC" conversion process, using a small high-frequency transformer to achieve voltage transformation and utilizing the principle of electromagnetic induction to transfer energy. Due to the high frequency, the core cross-sectional area and number of turns are significantly reduced, resulting in a significantly smaller size.

[0003] The utility model disclosed in CN209912703U is a surface mount electronic transformer. The top of the wire frame is provided with a groove, which can effectively dissipate the heat of the coil. The surface mount pins on the wire frame are also provided with heat dissipation holes to prevent the surface mount pins from deforming or falling off due to heat during soldering. In addition, the number of windings can be increased to 9-10 to meet the needs of multi-output.

[0004] The utility model with announcement number CN206460850U discloses a new type of surface mount electronic transformer. By setting a horizontal double-sided vertical winding method for flat copper wire and a surface mount structure for the skeleton, the flat wire vertical winding is changed to a surface mount SMD structure, which reduces the overall height of the product and can be used for automated plug-in production. This avoids the common problem that the flat wire vertical winding structure is a pin-type structure, which results in a large plate thickness and makes it impossible to use manual plug-in and automated plug-in production.

[0005] However, the above-disclosed surface mount electronic transformers still have the following problems in actual use: The windings are positioned by the transformer frame so that the surface mount welding can be carried out. However, the winding frame specifications of this type of transformer are fixed. After forming, it can only be installed on the lead windings of fixed specifications. It is impossible to effectively adjust the winding frame according to the needs of production and processing. Moreover, the multiple sets of windings on a single frame will also be deformed, which will affect the normal operation of the transformer.

[0006] Therefore, we propose a surface-mount electronic transformer to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a surface mount electronic transformer to solve the problem that existing transformers use a frame to position the windings for surface mount soldering. However, the winding frame of such transformers has fixed specifications, and after forming, it can only be installed on lead windings of fixed specifications. It is impossible to effectively adjust the winding frame according to production and processing needs. Furthermore, multiple sets of windings on a single frame will deform, which will affect the normal operation of the transformer.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a surface mount electronic transformer, comprising a transformer body and surface mount pins fixedly installed on the left and right sides of the rear of the transformer body;

[0009] The transformer body is provided with an adapter mechanism inside, and the adapter mechanism includes an adapter frame. An adapter liner is slidably provided on the outer side of the adapter frame at equal angles, and a lead winding is wound around the outer side of the adapter liner.

[0010] The adapter plate is provided with a positioning mechanism on its exterior, and the positioning mechanism includes a positioning pressure plate and a separating liner, which is used to separate and position the lead winding.

[0011] Preferably, the adapter mechanism includes an adapter frame that is fixedly installed at the center of the transformer body, and the adapter frame has an adapter groove at an equal angle on its exterior. The adapter groove is used to install the adapter liner, so that the adapter liner can slide inside the transformer body to adjust the installation requirements of different lead windings.

[0012] Preferably, the adapter mechanism includes a bidirectional threaded rod, which is rotatably mounted at the internal center of the adapter frame via a bearing. Guide sliders are threadedly connected to the upper and lower outer walls of the bidirectional threaded rod, and the outer walls of the symmetrically arranged guide sliders are hinged at equal angles to the inner end of the push-flipping rod.

[0013] Preferably, the adapter mechanism includes a guide slide, which is fixedly installed at the inner center of the adapter liner at equal angles. The upper and lower sides of the inner wall of the adapter liner are hinged to the outer end of the push-flipping rod, so that after the push-flipping rod rotates, it moves against the hinged guide slide and the adapter liner.

[0014] Preferably, the positioning mechanism includes positioning pressure plates that are slidably disposed at equal distances on the outer side of the adapter liner, and the inner ends of the positioning pressure plates that are slidably disposed at equal distances are fixedly connected to the outer ends of the main positioning slide rods on both the upper and lower sides. The inner ends of the symmetrically disposed main positioning slide rods are slidably connected to the guide slides on the inner side of the adapter liner, and the symmetrically disposed main positioning slide rods and guide slides are connected to each other by a return spring.

[0015] Preferably, the positioning mechanism includes a positioning groove, which is equally spaced inside the adapter liner. The positioning mechanism includes a partition liner that is slidably installed on the upper and lower sides of the symmetrically opened positioning groove. The partition liner is installed in pairs, and the partition liner and the positioning pressure plate are staggered.

[0016] Preferably, the positioning mechanism includes a secondary positioning slide rod, the inner end of which is fixedly connected to the center position of the inner side of the partition liner, and the inner end of which is slidably disposed through the guide slide on the inner side of the adapter liner. Moreover, the symmetrically arranged secondary positioning slide rods and the guide slide are connected to each other by abutment springs.

[0017] Preferably, the positioning mechanism includes a traction cable, and the outer end of the traction cable is fixedly connected to the inner end of the main positioning slide rod. After the guide slide is wound around the middle of the traction cable, its inner end is fixedly connected to the inner end of the auxiliary positioning slide rod. In the initial state, the positioning pressure plate is far away from the outer wall of the adapter liner so as to drive the partition liner to be stored in the positioning groove opened inside the adapter liner.

[0018] Preferably, the adapter mechanism includes adapter plates arranged in a "V" shape, and the adapter plates slide against the four corners of the outer side of the adapter frame. The installation of different specifications and requirements of the lead windings can be changed by sliding the adapter plates.

[0019] Preferably, the positioning mechanism includes positioning plates arranged in a "V" shape. The positioning plates are driven to slide inward by the winding of the lead wires, causing the corresponding separating liner to slide outward, thereby positioning each set of installed lead wires and preventing loosening or slippage.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The transformer of this surface mount electronics uses an adapter frame inside the transformer body to position the adapter bushing. The sliding adapter bushing changes the specifications and range of the lead winding during winding. At the same time, the positioning plate is squeezed during winding, causing the separating bushing to slide out, thereby separating and positioning the lead winding, avoiding loosening and slippage. The specific details are as follows:

[0021] 1. The adapter bobbin is installed at the center of the transformer body. The adapter liner is set at equal angles and is attached to the outside of the adapter bobbin in the initial state, so that it is distributed in the smallest specification during the winding process.

[0022] 2. Rotate the bidirectional threaded rod inside the adapter frame to drive the guide slider and the hinged push-flipping rod to slide inward synchronously. The push-flipping rod then slides outward against the guide slide and adapter liner at the outer end, causing the adapter liner, which is set at equal angles, to slide and change the winding range of the lead winding.

[0023] 3. The lead wire winding is wound around the positioning plate on the outside of the adapter liner. When winding, the positioning plate and the main guide slide rod slide inward, so that the positioning plate fits against the outer wall of the adapter liner. After the adapter liner is adjusted, the positioning plate and the lead wire winding come into contact with each other, thereby improving the fitting effect.

[0024] Furthermore, after the moving positioning pressure plate moves the main guide slide bar, the fixedly connected traction steel cable is loosened. The secondary positioning slide bar, which is not limited by the traction steel cable, is compressed by the contact spring, causing the separator liner to slide out of the positioning groove so that it protrudes from the outer wall of the positioning pressure plate. This separates and positions each group of lead windings to prevent loosening or slippage. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-10 The present invention provides the following technical solution:

[0038] Example 1: To address the problems existing in the practical use of surface mount electronic transformers, this example discloses the following technical solution: a surface mount electronic transformer, comprising a transformer body 1 and surface mount pins 2 fixedly installed on the left and right sides of the rear of the transformer body 1; an adapter mechanism is provided inside the transformer body 1, and the adapter mechanism includes an adapter frame 3, and an adapter liner 4 is slidably provided at equal angles on the outer side of the adapter frame 3, and lead windings 5 ​​are wound around the outer side of the adapter liner 4; the adapter frame 3 is fixedly installed at the center position inside the transformer body 1, and an adapter groove 8 is provided at equal angles on the outer side of the adapter frame 3, and the adapter groove 8 is used to install the adapter liner 4, so that the adapter liner 4 slides inside the transformer body 1 to adjust the installation requirements of different lead windings 5.

[0039] The adapter mechanism includes a bidirectional threaded rod 18, which is rotatably mounted at the center of the adapter frame 3 via bearings. Guide sliders 9 are threadedly connected to the upper and lower outer walls of the bidirectional threaded rod 18. The outer walls of the symmetrically arranged guide sliders 9 are hinged at equal angles to the inner end of the push-flipping rod 10. The adapter mechanism includes a guide slide 11, which is fixedly mounted at the center of the inner side of the adapter liner 4, which is set at equal angles. The upper and lower sides of the inner wall of the adapter liner 4 are hinged to the outer end of the push-flipping rod 10, so that after the push-flipping rod 10 rotates, it moves against the hinged guide slide 11 and the adapter liner 4.

[0040] The adapter mechanism includes adapter plates 4 arranged in a "V" shape, and the adapter plates 4 slide against the four corners of the outer side of the adapter frame 3. The installation of the lead winding 5 of different specifications and requirements can be changed by sliding the adapter plates 4.

[0041] like Figures 5-8 As shown, the transformer body 1 is installed and fixed to the adapter frame 3, and the adapter frame 3 is positioned for the guide slide 11 and the adapter liner 4 by the adapter slide 8 opened inside, so that the guide slide 11 and the adapter liner 4 are close to the outer wall of the adapter frame 3 in the initial state, so as to achieve the minimum size for the lead winding 5 to be installed.

[0042] Furthermore, when it is necessary to adjust the winding specifications, the bidirectional threaded rod 18 installed inside the adapter frame 3 is manually rotated. The guide slider 9, which is threadedly connected to the bidirectional threaded rod 18, is limited by the push-flipping rod 10. This allows the rotating bidirectional threaded rod 18 to drive the threaded guide slider 9 to slide inwards synchronously. The guide slider 9, in turn, drives the push-flipping rod 10, which is hinged to the outer wall, to rotate. This causes the push-flipping rod 10 to drive the guide slide 11, which is hinged to the outer end, and the adapter liner 4 to slide outwards synchronously. The adapter slide groove 8 on the outer side of the adapter frame 3 limits the sliding adapter liner 4 to prevent it from shifting or misaligning. At the same time, the outer diameter of the adapter frame 3 is changed by the outward sliding adapter liner 4, so that the lead winding 5 can be wound around the outer wall of the adapter liner 4, which is set at equal angles, thereby improving the range of winding compatibility.

[0043] Example 2: To address the problems existing in the practical use of current surface mount electronic transformers, this example discloses the following technical solution: A positioning mechanism is provided on the outside of the adapter plate 4, and the positioning mechanism includes a positioning pressure plate 6 and a separating liner 7. The separating liner 7 is used to separate and position the lead winding 5. The positioning pressure plate 6 included in the positioning mechanism is slidably disposed on the outside of the adapter plate 4 at equal distances, and the upper and lower sides of the inner ends of the equally spaced positioning pressure plates 6 are fixedly connected to the outer ends of the main positioning slide rod 12. The inner ends of the symmetrically disposed main positioning slide rod 12 are slidably connected to the guide slide 11 on the inner side of the adapter plate 4, and the symmetrically disposed main positioning slide rod 12 and guide slide 11 are connected to each other by a return spring 13.

[0044] The positioning mechanism includes a positioning slide groove 14, which is equidistantly opened inside the adapter liner 4. The positioning mechanism includes a partition liner 7, which is slidably installed on the upper and lower sides of the symmetrically opened positioning slide groove 14. The partition liner 7 is installed in pairs, and the partition liner 7 and the positioning pressure plate 6 are staggered. The positioning mechanism includes a secondary positioning slide rod 15, and the inner end of the secondary positioning slide rod 15 is fixedly connected to the center position of the inner side of the partition liner 7. The inner end of the secondary positioning slide rod 15 is slidably installed through the guide slide 11 inside the adapter liner 4. The symmetrically arranged secondary positioning slide rods 15 and the guide slide 11 are connected to each other by abutment springs 16.

[0045] The positioning mechanism includes a traction cable 17, the outer end of which is fixedly connected to the inner end of the main positioning slide rod 12. After the guide slide 11 is wound around the middle of the traction cable 17, its inner end is fixedly connected to the inner end of the auxiliary positioning slide rod 15. The positioning pressure plate 6 in the initial state is away from the outer wall of the adapter liner 4 so as to drive the partition liner 7 to be housed in the positioning groove 14 opened inside the adapter liner 4. The positioning pressure plate 6 included in the positioning mechanism is distributed in a "V" shape. The positioning pressure plate 6 is driven to slide inward by the winding of the lead wire winding 5, so that the positioning pressure plate 6 drives the corresponding partition liner 7 to slide outward, thereby positioning each set of installed lead wire windings 5 ​​to avoid loosening or slippage.

[0046] like Figures 8-10 As shown, during the winding process, the lead winding 5 contacts the positioning pressure plate 6 on the outer side of the adapter liner 4. After winding, the positioning pressure plate 6 is pressed and slides against the outer wall of the adapter liner 4. At the same time, the moving positioning pressure plate 6 drives the inner main positioning slide rod 12 to stretch the return spring 13 and loosen the traction steel cable 17 fixedly connected to the inner end. This causes the traction steel cable 17 to no longer limit the secondary positioning slide rod 15, so that after the spring 16 is compressed, the secondary positioning slide rod 15 and the separator liner 7 slide outward, thereby separating and positioning each set of lead windings 5 ​​to avoid loosening or slippage.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
