Description

TECHNICAL FIELD

[0001] The utility model relates to electronic component technology field especially relates to a kind of meet to strengthen insulation drive transformer structure. BACKGROUND

[0002] With the continuous development of electrical technology, especially in the wide application of high-voltage and high-power equipment, as a key power conversion element, the drive transformer plays a vital role. The traditional drive transformer design mostly adopts cavity structure, which can meet certain isolation and insulation requirements. However, due to the increasing requirements for the safety and stability of electrical equipment, especially the design requirements for enhanced insulation, higher challenges are put forward for the structure, size and performance of the drive transformer.

[0003] In the prior art, the traditional drive transformer can mostly only meet the lower isolation requirement, and can usually only meet the isolation voltage of 1500V. For higher voltage and power applications, the size and volume of the transformer often need to be increased to improve the insulation performance. At the same time, the increased volume makes these transformers no longer applicable in automated production and application scenarios with large space limitations.

[0004] In addition, the design of the traditional transformer often has a certain space waste, especially in the arrangement of the magnetic ring winding and the pin design, which fails to fully utilize the limited space. For the needs of automated production lines, the size and production process of the transformer also become important factors restricting its popularization and application.

[0005] Therefore, how to reduce the size of the drive transformer while ensuring high-voltage isolation and insulation performance, and ensure that it can adapt to automated production processes, has become a problem to be solved in the industry. SUMMARY

[0006] The purpose of the utility model is to provide a drive transformer structure that meets the requirements of enhanced insulation and has a smaller size. By improving the design of the traditional drive transformer, the invention can realize a smaller volume while ensuring electrical isolation performance, and has the functions of supporting automatic patching and reflow soldering, which meets the needs of modern automated production lines.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Bridge skeleton structure: the invention adopts a bridge skeleton structure (such as Figure 1The top of the bridge-shaped skeleton is flat and stable, which can effectively accommodate various components of the transformer. The bridge-shaped design has high space utilization, which can optimize the layout of the magnetic ring winding. Due to the higher magnetic ring winding installation space provided by the bridge-shaped skeleton, the power output of the transformer can be effectively increased, while the size of the transformer is controlled while ensuring enhanced insulation requirements.

[0009] Reasonable pin design: the number of pins of the transformer (as shown in Figure 2 The distance between the pins is greater than 6.5mm, which meets the enhanced insulation requirements and effectively prevents electrical short circuit and leakage current, ensuring the safety of the transformer in high voltage applications.

[0010] Reasonable layout of magnetic ring winding: the magnetic ring winding is installed below the bridge of the bridge-shaped skeleton, which ensures sufficient electrical isolation and insulation performance. The relative position of the magnetic ring winding is greater than 6.5mm, which meets the insulation and isolation requirements. This design effectively avoids electrical short circuit and other safety hazards, improves the working stability and safety of the transformer.

[0011] Adapt to automatic production process: the drive transformer of the present application supports surface mount (SMT) process, which can adapt to high-speed mounting of automatic chip mounter, and the design is compatible with reflow soldering process. This design can effectively improve production efficiency, reduce production cost, and ensure the installation precision and reliability of the transformer.

[0012] Improve power and voltage carrying capacity: compared with the traditional cavity structure, the bridge-shaped skeleton design of the present application can provide more power and voltage application space, which is suitable for high voltage electrical equipment and industrial control system scenes. Due to the higher window utilization rate provided by the bridge-shaped skeleton, the transformer can still meet the high power demand in a smaller size.

[0013] The beneficial effects of the present application are as follows:

[0014] Improve the safety of the transformer: adopt enhanced insulation design to ensure the safety and stability of the transformer in high voltage applications.

[0015] Reduce the volume: optimize the space utilization rate through the bridge-shaped skeleton structure, realize the design of small size drive transformer, and adapt to the application demand of limited space.

[0016] Adapt to modern automatic production: the transformer supports surface mount and reflow soldering, which adapts to modern automatic production process, can improve production efficiency and reduce production cost.

[0017] Enhance the power carrying capacity: in a smaller size, it can still provide larger power output, which is suitable for higher voltage and power application scenarios.

[0018] The driving transformer structure provided by the utility model has the advantages of high-voltage isolation, enhanced insulation, compact size and automatic production, and has a wide application prospect, especially in high-voltage electrical equipment and automatic production lines.

[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0028] The specific embodiments of the application will be described in detail with reference to the accompanying drawings. The technical scheme of the application is illustrated by the following examples, but does not limit the scope of the application.

[0029] Example 1: a reinforced insulation driving transformer structure

[0030] As Figures 1-6 shown, the present application provides a drive transformer that meets the requirements of enhanced insulation, which includes a bridge skeleton, pins, and a magnetic ring winding, with the specific structure as follows:

[0031] Bridge skeleton 1:

[0032] The bridge skeleton 1 is made of plastic or other insulating materials, with good mechanical strength and electrical insulation performance. Its shape is a bridge structure, with a flat top that can effectively support the components of the entire transformer. The bottom of both sides of the bridge skeleton is designed with 10 pin mounting positions to connect with the circuit board.

[0033] The design of the bridge skeleton allows the magnetic ring winding 3 to be installed below the bridge, with a distance greater than 6.5mm from the pins 2 to meet the requirements of enhanced insulation. At the same time, the structure of the bridge skeleton makes the layout of the magnetic ring winding more compact, improving the space utilization.

[0034] Pin 2:

[0035] The pin 2 is located at the bottom of both ends of the bridge skeleton 1, with a total of 10 pins arranged in a predetermined manner. The distance between the pins 2 is greater than 6.5mm, meeting the electrical isolation requirements, which can effectively prevent electrical short circuit or electrical leakage phenomena that may occur in high-voltage electrical equipment.

[0036] The material of the pin is metal (such as copper alloy), with a tin-plated surface to improve the contact performance and welding strength. The number and arrangement of the pins can be adjusted according to the specific application requirements to adapt to different voltage and power driving requirements.

[0037] Magnetic ring winding 3:

[0038] The magnetic ring winding 3 is wound by enameled wire and placed below the bridge of the bridge skeleton 1. The core part of the winding is a ferrite core with high magnetic permeability and low magnetic loss. Through appropriate winding methods, the transformer can provide the required power and voltage.

[0039] The design of the magnetic ring winding ensures electrical isolation and insulation performance, while effectively improving the working efficiency and voltage stability of the transformer.

[0040] Example 2: Automated production process

[0041] In order to adapt to the needs of modern automated production, the drive transformer design of the present application supports surface mount technology (SMT). The specific production process is as follows:

[0042] Automatic patching:

[0043] The bridge skeleton 1 adopts a surface mount design, suitable for high-speed mounting by automated mounting equipment. The mounting machine accurately installs the drive transformer onto the circuit board according to the pin positions on the board.

[0044] Reflow soldering:

[0045] After the transformer is installed, the circuit board will enter a reflow soldering oven for soldering. During the reflow soldering process, the solder melts during heating, completing the soldering. Since the pin 2 and the circuit board design are compatible with the reflow soldering process, the entire transformer installation can be efficiently and accurately completed.

[0046] Function detection:

[0047] After completing the reflow soldering, the transformer assembly is complete, and electrical performance testing is performed. During testing, the isolation performance and electrical parameters are checked to ensure they meet design requirements, such as voltage and power stability.

[0048] Example 3: Specific design for enhancing insulation performance

[0049] In the structural design of the invention, special attention is paid to the spacing between pins 2 and the structure of skeleton 1 to ensure that the transformer has good reinforced insulation performance, meeting the needs of high-voltage applications:

[0050] Pin spacing design:

[0051] The minimum spacing between pins 2 is 6.5mm, which meets international electrical safety standards (such as IEC or UL standards). This spacing is large enough to effectively isolate electrical signals between pins and prevent possible short circuit problems.

[0052] Isolation design of skeleton and magnetic ring winding:

[0053] The relative position design of the bridge skeleton 1 and the magnetic ring winding 3 ensures sufficient electrical isolation. The bridge skeleton 1 effectively prevents high voltage from affecting the low voltage part and ensures the electrical safety of the transformer.

[0054] Insulating material selection:

[0055] All materials that come into contact with electrical parts (such as bridge skeletons, pins, windings, etc.) are made of materials with high insulation performance (such as epoxy resin, polyimide, etc.), ensuring that the transformer can still maintain good insulation effect in a high-voltage environment.

[0056] Example 4: Application scenarios

[0057] The drive transformer of the invention is particularly suitable for the following application scenarios:

[0058] High-voltage electrical equipment:

[0059] The driving transformer of the present application can withstand high voltage and large power, and is widely used in high-voltage electrical equipment such as industrial control systems, automation equipment, and power electronic equipment.

[0060] Automated production line:

[0061] Due to the support of surface mounting and reflow soldering, the transformer of the present application is suitable for mass production in an automated production line. Its stable performance and efficient production process make the transformer have good market competitiveness in industrial applications.

[0062] Consumer electronics:

[0063] The transformer of the present application can also be applied to consumer electronics products such as smart home devices, power tools, and small household appliances, providing efficient power conversion and safety protection due to its small and compact design.
