Description

Technical Field

[0001] This invention relates to the field of industrial equipment, and more particularly to the field of transformers, specifically to a transformer fixing device that is easy to install. Background Technology

[0002] Transformers are common components in industrial equipment. Older transformers typically use a pin-type structure and are welded using wave soldering. Newer ferrite-type transformers, however, require bonding through the circuit board and simultaneously to both the circuit board and the other half of the transformer to meet performance requirements. Currently, the adhesives used in ferrite-type transformers must be thick enough not to affect the transformer's performance while ensuring sufficient bonding strength. High-strength adhesives on the market require 24 hours to reach maximum strength. During the cooling period, a fixing device is needed to secure the transformer and prevent displacement, detachment, or insufficient adhesion. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a transformer fixing device that is easy to install, compact in structure, and has a wide range of applications.

[0004] To achieve the above objectives, the present invention provides a transformer fixing device that is easy to install, as follows:

[0005] The main feature of this easy-to-install transformer fixing device is that the device includes a transformer body and fastening components. The fastening components are used to fix the transformer body and include a circuit board, a pressure block, a Torx nut, a spring stud, and a spring. The transformer body is mounted and fixed on the circuit board, and the pressure block is located on the upper surface of the transformer. The Torx nut, spring stud, and spring cooperate to fix the transformer body and the pressure block. The transformer body is a ferrite transformer.

[0006] Preferably, the spring is sleeved on the outside of the spring stud, the nut is fixed to the top of the spring stud, and both the spring stud and the spring are placed on the pressure block.

[0007] Preferably, the pressure block is provided with a countersunk hole and a through hole, the spring is placed in the countersunk hole, and the spring stud moves up and down in the through hole.

[0008] Preferably, the transformer body includes a first transformer and a second transformer. The circuit board has a groove and a U-shaped groove. The first transformer, coated with adhesive, is placed in the corresponding groove of the circuit board. The pressure block is placed on the first transformer. The rotation of the nut compresses the spring, pushing the spring stud through the through hole of the pressure block and into the long side of the U-shaped groove of the circuit board. The first transformer passes through the groove and is exposed. The second transformer is placed directly in the position corresponding to the first transformer.

[0009] Preferably, the fastening component further includes a limiting pin, which is mounted on a spring stud. After the spring stud passes through the circuit board, the limiting pin is engaged in the short side of the U-shaped groove of the circuit board. The limiting pin cooperates with the pressure block to make the transformer body and the circuit board fit tightly together under the action of the spring.

[0010] Preferably, the fastening component further includes a strong magnet, which is attached to the lower surface of the second transformer to bond the second transformer and the first transformer together.

[0011] Preferably, the pressure block has a through hole located at each of its four corners, and each corresponding to one of four sets of plum blossom nuts, spring studs and springs.

[0012] Preferably, the countersunk hole of the pressure block has a chamfered structure around it, which is used to adjust the size of the pressure block according to the size of the transformer, so as to adapt to the specifications of different transformers.

[0028] To more clearly describe the technical content of the present invention, the following description is provided in conjunction with specific embodiments.

[0029] The present invention provides an easy-to-install transformer fixing device, which includes a transformer body and fastening components. The fastening components are used to fix the transformer body and include a circuit board 1, a pressure block 4, a nut 5, a spring stud 6, and a spring 8. The transformer body is mounted and fixed on the circuit board 1, and the pressure block 4 is located on the upper surface of the transformer. The nut 5, the spring stud 6, and the spring 8 cooperate to fix the transformer body and the pressure block 4. The transformer body is a ferrite transformer.

[0030] In a preferred embodiment of the present invention, the spring 8 is sleeved on the spring stud 6, the plum nut 5 is fixed to the top of the spring stud 6, and both the spring stud 6 and the spring 8 are placed on the pressure block 4.

[0031] In a preferred embodiment of the present invention, the pressure block 4 is provided with a countersunk hole and a through hole, the spring 8 is placed in the countersunk hole, and the spring stud 6 moves up and down in the through hole.

[0032] In a preferred embodiment of the present invention, the transformer body includes a first transformer 3 and a second transformer 2. The circuit board 1 is provided with a groove and a U-shaped groove. The first transformer 3, coated with adhesive, is placed in the corresponding groove of the circuit board 1. The pressure block 4 is placed on the first transformer 3. The nut 5 is rotated to compress the spring 8, pushing the spring stud 6 through the through hole of the pressure block 4 and into the long side of the U-shaped groove of the circuit board 1. The first transformer 3 passes through the groove and is exposed. The second transformer 2 is placed directly in the position corresponding to the first transformer 3 without passing through the groove.

[0033] In a preferred embodiment of the present invention, the fastening component further includes a limiting pin 7, which is mounted on a spring stud 6. After the spring stud 6 passes through the circuit board 1, the limiting pin 7 is engaged in the short side of the U-shaped groove of the circuit board 1. The limiting pin 7 cooperates with the pressure block 4, and under the action of the spring 8, the transformer body is tightly attached to the circuit board 1.

[0034] In a preferred embodiment of the present invention, the fastening component further includes a strong magnet 9, which is adsorbed and installed on the lower surface of the second transformer 2 to bond the second transformer 2 and the first transformer 3 together. Under the action of the strong magnet, the second transformer and the first transformer will generate magnetism and attract each other.

[0035] In a preferred embodiment of the present invention, the pressure block 4 has four through holes, which are located at the four corners of the pressure block 4 and correspond to four sets of plum blossom nuts 5, spring studs 6 and springs 8 respectively.

[0036] In a preferred embodiment of the present invention, the countersunk hole of the pressure block 4 has a chamfered structure around it, which is used to adjust the size of the pressure block 4 according to the size of the transformer and adapt to the specifications of different transformers.

[0037] In a specific embodiment of the present invention, a transformer body and fastening components for fixing the transformer are included. The fastening components include a circuit board 1 placed on the transformer body, a pressure block 4 on the upper surface of the transformer, a nut 5, a spring stud 6, a spring 8, a limiting pin 7, and a strong magnet 9 on the lower surface of the transformer. The fixing device of the present invention, through the nut 5, spring stud 6, spring 8, limiting pin 7, and strong magnet 9, enables rapid installation of the transformer and can be adjusted in a timely manner according to the height, size, and adhesive strength of the transformer to adapt to different types of transformers.

[0038] This transformer fixing device includes a pressure block 4, which has a set of supporting mechanisms such as a plum nut 5, a spring stud 6, a spring 8, and a limiting pin 7. The plum nut 5, spring stud 6, and spring 8 are fitted together and placed in the corresponding through holes of the pressure block 4. The limiting pin 7 protrudes from the other side of the pressure block 4 for limiting the position. There are four through holes. This device uses the pressure block 4, plum nut 5, spring stud 6, spring 8, and limiting pin 7 to form a quick fixing device. This transformer fixing device is used in conjunction with the circuit board 1 on which the transformer is placed and a strong magnet 9 to ensure the clamping force between the first transformer and the circuit board. Depending on the type of ferrite transformer, the strong magnet 9 is used to ensure the clamping force between the second transformer and the first transformer.

[0039] The present invention uses a plum nut 5, a spring stud 6, a spring 8, a limiting pin 7 and a pressure block 4 to bond the transformer and the circuit board 1, so that the transformer and the circuit board 1 are tightly bonded. A strong magnet 9 is used to bond the transformer and the other half of the transformer, so that the two are tightly bonded together.

[0040] The pressure block 4 of this device is provided with a countersunk hole and a through hole. The countersunk hole is used to place the spring 8, and the through hole allows the spring stud 6 to move freely up and down. The pressure block 4 also has a recessed groove for fixing and limiting the transformer. To facilitate the smooth insertion of the transformer, a chamfered structure is added around the recessed groove of the pressure block 4. The size of the pressure block 4 can be adjusted according to the size of the transformer to accommodate transformers of different sizes and specifications.

[0041] The spring stud 6 and spring 8 can be adjusted according to the clamping force required by different types of transformers, and the limit pin 7 can be adjusted according to the size of the U-shaped groove of the circuit board 1.

[0042] The first transformer 3 is coated with adhesive and placed in the corresponding groove of the circuit board 1. A quick fixing device consisting of a pressure block 4, a nut 5, a spring stud 6, a spring 8, and a limiting pin 7 is then placed in the groove. The nut 5 is rotated and the spring 8 is compressed, pushing the spring stud 6 through the long side of the U-shaped groove in the circuit board 1. After passing through the circuit board 1, the nut 5 is rotated so that the limiting pin 7 is engaged in the short side of the U-shaped groove in the circuit board 1. At this point, the installation of the first transformer 3 is complete.

[0043] After the second transformer 2 is coated with adhesive, it is placed in a position opposite to the first transformer 3. After placement, a strong magnet 9 is placed on the surface of the second transformer 2, and the installation of the second transformer 2 is now complete.

[0044] After the adhesive has fully cured, the strong magnet 9 can be quickly removed by sliding. Then rotate the nut 5 and rotate the spring stud 6 to rotate the limit pin 7 to the short side of the U-shaped groove on the circuit board 1. The spring 8 will pop out automatically, and the quick fixing device can be quickly removed.

[0045] When installing the transformer, a groove is cut into the pressure block 4 to allow it to fit into the transformer. Pressing down the nut 5 moves the limiting pin 7 through the long side of the corresponding U-shaped groove on the circuit board 1. Then, rotating the nut 5 causes the limiting pin 7 to engage with the short side of the U-shaped groove on the circuit board 1, thus applying pressure to the transformer. When installing the other half of the transformer, the transformers attract each other under the influence of the magnet, similar to two magnets attracting each other. The first transformer, the second transformer, and the magnet are pressed together and attract each other. A strong magnet 9 is placed to firmly attract the two. During disassembly, the strong magnet 9 is moved horizontally to remove it, and then the nut 5 is rotated to allow the limiting pin 7 to pass through the long side of the U-shaped groove on the circuit board 1, thus separating them. This achieves quick disassembly and assembly, and allows for reuse.

[0046] The pressure block 4 in this application is a single component, not a support, but rather serves as a pressure block and limiter, providing force for the transformer's connection and fixation. The transformer in this application is a ferrite type transformer, using two ferrite cores in combination, rather than being wound with copper wire. The spring 8 in this application provides a reaction force to the pressure plate. When the limit pin 7 exits from the circuit board 1, it quickly resets the spring stud 6, facilitating rapid installation next time. Simultaneously, when the spring 8 is in operation, it is in a compressed state, and the reaction force supports the pressure block 4.

[0047] The pressure block 4, spring 8, and limiting pin 7 are commonly used in the field to fix transformers, but only when the transformer is a single unit. However, the transformer in this device is composed of two ferrite cores, making it impossible to fix with a single fixing device. While two fixing devices could be used, this would not achieve quick disassembly, would be compact, and would occupy a large space. Using a strong magnet 9 alone can only fix the two ferrite transformers together, but it cannot strongly bond the transformer to the circuit board 1. Therefore, using one fixing device plus one strong magnet 9 is sufficient for quick fixing and disassembly.

[0048] To ensure that the transformer can be evenly bonded to the circuit board 1 and that the force distribution is uniform, four fixing points are selected for fixing, namely four springs 8, four spring studs 6 and four limit pins 7. At the same time, if two fixing devices are used for fixing at the same time, eight holes need to be drilled on the circuit board 1, which takes up space, and the other fixing device needs to be larger. Otherwise, the two fixing devices will interfere and overlap when in use.
