Description

Technical Field

[0001] The utility model belongs to the technical field of capacitors, and in particular relates to a film capacitor with a positioning structure. Background Art

[0002] Film capacitors are capacitors that use metal foil or metallized film as electrodes and insulating materials such as plastic film as dielectrics. They are widely used in power filtering, coupling, bypass and other circuits in electronic devices such as televisions, computers, mobile phones, and audio equipment.

[0003] However, during installation and use, problems such as unstable performance and poor connection often occur due to inaccurate positioning. Existing film capacitors lack an effective positioning structure, which brings many inconveniences to production and use. Summary of the Invention

[0004] The present invention aims to solve the problem that the existing technology cannot effectively locate the device, which limits the stability of the device in actual use, and proposes the following technical solutions:

[0005] A film capacitor with a positioning structure includes a film capacitor, positioning structures are provided on both sides of the film capacitor, the positioning structure includes a fixed block, an internally and externally threaded hollow column and a first spring, the internally and externally threaded hollow column is fixedly connected to the top of the fixed block, the first spring is sleeved and installed on the internally and externally threaded hollow column, one end of the first spring is connected to the top of the fixed block, and the other end of the first spring is fixedly connected to an angle fixing block, the angle fixing block is slidably connected to the outside of the internally and externally threaded hollow column, and a threaded fastener is provided at one end of the angle fixing block away from the internally and externally threaded hollow column, and the threaded fastener is threadedly connected to the internally and externally threaded hollow column;

[0006] A positioning pin is slidably installed inside the internal and external threaded hollow column, a second spring is sleeved and installed above the positioning pin, and a hexagonal countersunk bolt is provided at one end of the second spring away from the positioning pin, and the hexagonal countersunk bolt is threadedly connected to the inside of the internal and external threaded hollow column.

[0007] The hexagon socket countersunk bolt is rotated to squeeze the second spring to act on the locating pin, so that the bottom end of the locating pin presses against the bottom of the horizontal slide groove for positioning the fixed block. The angle fixing block is squeezed by rotating the threaded fastener. However, when the angle fixing block squeezes the first spring, the first spring also gives the angle fixing block an upward force, forming a double guarantee with the fixation of the threaded fastener. The elastic force of the first spring can offset part of the external force, reduce the possibility of loosening of the threaded fastener, and further enhance the reliability of the fixation.

[0008] As a preferred embodiment of the above technical solution, the fixing block is located at the bottom end of the film capacitor, and the side wall of the angle fixing block is in contact with the side wall of the film capacitor.

[0009] At the same time, according to the rotation angle of the film capacitor, the angle fixing block fits with the side wall of the film capacitor. This is very important in some application scenarios with strict requirements on the installation angle. It can ensure that the capacitor can be effectively fixed at any angle, thereby exerting the best performance of the film capacitor.

[0010] As a preferred embodiment of the above technical solution, the fixed block is slidably connected to a transverse sliding groove provided on the upper surface of the sliding seat.

[0011] Installation by sliding grooves eliminates the need for complex alignment and adjustment operations, greatly improving installation efficiency while effectively preventing film capacitors from loosening or shifting due to vibration, impact or other external forces during use.

[0012] As a preferred embodiment of the above technical solution, a horizontal sliding block is slidably connected to the horizontal sliding groove, a rotating pin is fixedly connected above the horizontal sliding block, the rotating pin is rotatably connected to a cross fixing frame at one end away from the horizontal sliding block, and the cross fixing frame is fixedly connected to the film capacitor at one end away from the rotating pin.

[0013] The cross fixing frame effectively supports the film capacitor to prevent it from shifting due to gravity. The slider can quickly adjust the position of the film capacitor to improve installation efficiency.

[0014] As a preferred embodiment of the above technical solution, the sliding seat is slidably connected to a longitudinal sliding groove provided on the surface of the fixed base, and two longitudinal positioning blocks are provided on each side of the sliding seat.

[0015] The position adjustment of the capacitor in both horizontal and vertical dimensions can accurately locate the capacitor in the optimal position according to the specific circuit layout and space requirements, improving the flexibility and adaptability of installation.

[0016] As a preferred embodiment of the above technical solution, the longitudinal positioning block is slidably connected to the longitudinal slide groove, and a fixing bolt is threadedly connected to the longitudinal positioning block. The fixing bolt passes through the longitudinal positioning block and abuts against the bottom of the longitudinal slide groove.

[0017] The film capacitor is effectively secured and quickly fixed by sliding the longitudinal positioning block and fixing with fixing bolts.

[0018] As a preferred embodiment of the above technical solution, a plurality of fixed countersunk holes are fixedly installed on the fixed base for fixing the fixed base.

[0019] The film capacitor is fixed as a whole through the fixing countersunk holes.

[0020] The beneficial effects of the utility model are:

[0021] 1. The angle fixing block fits against the side wall of the film capacitor, which is very important in some application scenarios with strict requirements on installation angles. It can ensure that the capacitor can be effectively fixed at any angle, thereby achieving the best performance of the film capacitor. The first spring also applies an upward force to the angle fixing block, forming a double guarantee with the fixation of the threaded fastener. The elastic force of the first spring can offset some external forces, reduce the possibility of loosening of the threaded fastener, and further enhance the reliability of fixation.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example

[0029] Figures 1-4 What is shown is a schematic diagram of the overall structure of a specific embodiment of the utility model. Figures 1-4In the figure, a film capacitor with a positioning structure includes a film capacitor 2, and a positioning structure 1 is provided on both sides of the film capacitor 2. The positioning structure 1 includes a fixed block 106, an internally and externally threaded hollow column 105 and a first spring 104. The internally and externally threaded hollow column 105 is fixedly connected to the top of the fixed block 106, and the first spring 104 is sleeved and installed on the internally and externally threaded hollow column 105. One end of the first spring 104 is connected to the top of the fixed block 106, and the other end of the first spring 104 is fixedly connected to the angle fixing block 103. The angle fixing block 103 is slidably connected to the outside of the internally and externally threaded hollow column 105. A threaded fastener 102 is provided at one end of the angle fixing block 103 away from the internally and externally threaded hollow column 105, and the threaded fastener 102 is threadedly connected to the internally and externally threaded hollow column 105;

[0030] A positioning pin 108 is slidably installed inside the internal and external threaded hollow column 105, and a second spring 107 is sleeved and installed above the positioning pin 108. A hexagon socket countersunk bolt 101 is provided at one end of the second spring 107 away from the positioning pin 108, and the hexagon socket countersunk bolt 101 is threadedly connected to the inside of the internal and external threaded hollow column 105.

[0031] In this way, the hexagon socket countersunk bolt 101 is rotated to squeeze the second spring 107 to act on the positioning pin 108, so that the bottom end of the positioning pin 108 is against the bottom of the horizontal slide groove 301, which is used to position the fixing block 106. At the same time, according to the rotation angle of the film capacitor 2, the angle fixing block 103 is fitted with the side wall of the film capacitor 2. This is very important in some application scenarios with strict requirements on the installation angle. It can ensure that the capacitor can be effectively fixed at any angle, thereby giving full play to the optimal performance of the film capacitor 2. The angle fixing block 103 is squeezed by the threaded fastener 102. However, when the angle fixing block 103 squeezes the first spring 104, the first spring 104 also gives the angle fixing block 103 an upward force, forming a double guarantee with the fixation of the threaded fastener 102. The elastic force of the first spring 104 can offset part of the external force, reduce the possibility of loosening of the threaded fastener 102, and further enhance the reliability of the fixation.

[0032] Figure 1 What is shown is a structural schematic diagram of a specific embodiment of the utility model.

[0033] Figure 1 Furthermore, the fixing block 106 is located at the bottom end of the film capacitor 2 , and the side wall of the angle fixing block 103 is in contact with the side wall of the film capacitor 2 .

[0034] The fixing block 106 is slidably connected to a transverse sliding groove 301 formed on the upper surface of the sliding seat 3 .

[0035] In this way, the sliding of the fixed block 106 in the horizontal slide groove 301 provides a clear installation path for the fixed block 106, so that when installing the film capacitor 2, the fixed block 106 can be quickly and accurately slid into the corresponding position without the need for complicated alignment and adjustment operations, which greatly improves the installation efficiency. At the same time, it effectively prevents the film capacitor 2 from loosening or shifting due to vibration, impact or other external forces during use, ensuring that the film capacitor 2 always remains in the correct position. If the film capacitor 2 needs to be positioned or replaced with a different model of film capacitor 2, the fixed block 106 can be easily slid out of the slide groove to perform corresponding adjustments or replacement operations.

[0036] Figure 3 、 Figure 4 What is shown is a structural schematic diagram of a specific embodiment of the utility model.

[0037] Figure 3 、 Figure 4 In the figure, a horizontal sliding block 203 is slidably connected to the horizontal sliding groove 301, a rotating pin 202 is fixedly connected above the horizontal sliding block 203, the rotating pin 202 is rotatably connected to the cross fixing frame 201 at one end away from the horizontal sliding block 203, and the cross fixing frame 201 is fixedly connected to the film capacitor 2 at one end away from the rotating pin 202.

[0038] The sliding seat 3 is slidably connected to a longitudinal sliding groove 402 provided on the surface of the fixed base 4 , and two longitudinal positioning blocks 403 are respectively provided on both sides of the sliding seat 3 .

[0039] The longitudinal positioning block 403 is slidably connected to the longitudinal slide groove 402 . A fixing bolt 404 is threadedly connected to the longitudinal positioning block 403 . The fixing bolt 404 passes through the longitudinal positioning block 403 and abuts against the bottom of the longitudinal slide groove 402 .

[0040] A plurality of fixed countersunk holes 401 are fixedly installed on the fixed base 4 for fixing the fixed base 4 .

[0041] In this way, the rotating pin 202 allows the film capacitor 2 to rotate at multiple angles within a certain range. At the same time, the horizontal sliding block 203 slides in the horizontal slide groove 301 to move the film capacitor 2 laterally. The sliding seat 3 slides on the longitudinal slide groove 402 at its lower end to achieve longitudinal movement of the film capacitor 2. The multi-angle rotation of the rotating pin 202, the horizontal sliding of the horizontal sliding block 203 and the longitudinal sliding of the sliding seat 3 enable the film capacitor 2 to adapt to various installation environments. The film capacitor 2 that can rotate at an angle and move laterally and longitudinally can adapt to different application scenarios and working conditions. Whether in small electronic devices or large industrial control systems, it can be adjusted according to specific needs to meet the requirements of various applications.

[0042] Working principle: The rotating pin 202 allows the film capacitor 2 to rotate at multiple angles within a certain range. At the same time, the transverse sliding block 203 slides in the transverse slot 301 to move the film capacitor 2 laterally. The sliding seat 3 slides on the longitudinal slot 402 at its lower end to realize the longitudinal movement of the film capacitor 2. The multi-angle rotation of the rotating pin 202, the transverse sliding block 203 slides laterally, and the sliding seat 3 slides longitudinally, so that the film capacitor 2 can adapt to various installation environments. The film capacitor 2 that can rotate at an angle and move laterally and longitudinally can adapt to different application scenarios and working conditions. Whether in small electronic devices or large industrial control systems, it can be adjusted according to specific needs to meet the requirements of various applications. The sliding of the fixed block 106 in the transverse slot 301 provides a clear installation path for the fixed block 106, so that when installing the film capacitor 2, the fixed block 106 can be quickly and accurately slid into the corresponding position without the need for complicated alignment and adjustment operations, which greatly improves the installation efficiency and effectively prevents the film capacitor 2 from loosening or shifting due to vibration, impact or other external forces during use, ensuring the film The film capacitor 2 is always kept in the correct position. If the position of the film capacitor 2 is needed or a different type of film capacitor 2 is replaced, the fixing block 106 can be easily slid out of the slide slot to make corresponding adjustments or replacement operations. The hexagonal countersunk bolt 101 is rotated to squeeze the second spring 107 to act on the positioning pin 108, so that the bottom end of the positioning pin 108 is against the bottom of the horizontal slide slot 301 for positioning the fixing block 106. At the same time, according to the rotation angle of the film capacitor 2, the angle fixing block 103 is fitted with the side wall of the film capacitor 2. This is suitable for some installations with strict requirements on the installation angle. The angle fixing block 103 is rotated and squeezed by the threaded fastener 102. However, when the angle fixing block 103 squeezes the first spring 104, the first spring 104 also gives the angle fixing block 103 an upward force, forming a double guarantee with the fixation of the threaded fastener 102. The elastic force of the first spring 104 can offset part of the external force, reduce the possibility of the threaded fastener 102 loosening, and further enhance the reliability of the fixation.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
