Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a portable electronic information filter. Background Technology

[0002] As an important frequency selection device, filters play a crucial role in the field of electronics. They allow specific frequency components to pass through while attenuating other frequency components. Filters can effectively filter out specific frequency points or frequencies other than those in a power line to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency has been eliminated.

[0003] In the prior art, such as in publication number CN221688961U, a portable electronic information filter is disclosed, including a shielding cover. A filter body is placed inside the shielding cover, and a shock-absorbing component is installed between the shielding cover and the filter body. The shock-absorbing component includes a limiting block. The limiting block is welded to the inner wall of the shielding cover, and a sliding groove is formed inside the limiting block. A rod groove is formed on the top plate of the limiting block. A moving rod is welded to the outer wall of the filter body. The moving rod passes through the rod groove and extends into the sliding groove. A slider is welded to the bottom side of the moving rod. A first spring is welded to the outer wall of the filter body. The bottom wall of the first spring is fixedly connected to the top side of the moving rod. The first spring is sleeved around the moving rod. Shock-absorbing components are installed on the side walls and bottom walls of the filter body. The impact force and vibration are absorbed by the elastic deformation of the first spring and the resistance of friction, which is beneficial to improving the protection of the filter.

[0004] However, although the aforementioned portable electronic information filter protects the filter by setting up shock-absorbing components, the connection terminals of the filter and the shield are usually fixedly connected. When maintaining the inside of the filter, it is necessary to cut off the connection terminals of the filter and the shield before the filter can be separated from the shield. It may even be necessary to remove the wires on each terminal outside the shield one by one. This can easily damage the filter and the maintenance process is complicated. Therefore, this utility model provides a portable electronic information filter. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a portable electronic information filter, which solves the problem of inconvenient filter maintenance caused by the difficulty in removing the filter and its housing in existing technologies.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a portable electronic information filter, including a protective cover and a filter module located inside it. One side of the protective cover is provided with a row of terminal input terminals, and the other side of the protective cover is provided with a row of terminal output terminals. A conductive sheet is fixedly connected to one end of each terminal input terminal and terminal output terminal. Multiple conductive layers for bonding and conducting electricity with the conductive sheets are formed on the upper surface of the filter module. Two bolts are threaded through the top of the protective cover, and a rotating shaft is rotatably connected to the bottom end of the bolts. A pressure plate is fixedly connected to the bottom end of the rotating shaft.

[0007] Preferably, the number of input terminals and output terminals in each row is the same and they correspond to each other on the left and right. Each input terminal and output terminal is electrically connected to a conductive sheet, and the input terminals and output terminals are also electrically connected to external wires.

[0008] Preferably, the conductive sheet has a curved structure, and each conductive sheet has an elastic band made of rubber fitted on its outer surface. The inner wall of the protective cover is also fixedly provided with a hanger for hanging the elastic band. The hanger includes a fixing block, a hanging post is fixedly connected to one side of the fixing block, and a stop block is fixedly connected to one side of the hanging post.

[0009] Preferably, the bottom of the filter module is fixedly connected to a base plate, the base plate is sealed and connected to the protective cover from top to bottom, and the front and rear surfaces of the filter module are engaged and connected to the front and rear inner walls of the protective cover.

[0010] Preferably, the number of conductive sheets is the same as the number of conductive layers. The conductive sheets include a vertical portion and an inclined portion. The vertical portion is located on one side of the filter module, and the inclined portion is located diagonally above the filter module.

[0011] Preferably, the length of the pressure plate is greater than the maximum distance between multiple conductive layers on any side, and the pressure plate is made of polyethylene. Each pressure plate has springs fixedly connected to both sides of its top end, and the top ends of the springs are fixedly connected to the top inner wall of the protective cover. Beneficial effects

[0012] This invention provides a portable electronic information filter. Compared with the prior art, it has the following advantages: By setting the connection between the protective cover and the filter module terminals to be on / off, when the filter is in normal use, rotating the bolts causes the pressure plate to simultaneously press down multiple conductive plates below until the conductive plates are firmly pressed into the conductive layer of the filter module. When the filter needs maintenance, rotating the bolts causes the pressure plate to move the conductive plates away from the conductive layer. At this time, the terminals of the protective cover and the filter module are disconnected, and the two can be separated along their mating direction to achieve the disassembly effect, which provides convenience for the maintenance of the filter module.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Figures 1-6An embodiment is shown: A portable electronic information filter includes a protective cover 1 and a filter module 3 located inside it. A row of input terminals 11 is provided on one side of the protective cover 1, and a row of output terminals 12 is provided on the other side of the protective cover 1. A conductive sheet 13 is fixedly connected to one end of each input terminal 11 and output terminal 12. Multiple conductive layers 31 for contacting and conducting electricity with the conductive sheets 13 are formed on the upper surface of the filter module 3. Two bolts 4 are threaded through the top of the protective cover 1, and a rotating shaft 41 is rotatably connected to the bottom end of each bolt 4. A pressure plate 42 is fixedly connected to connect the input end of the external wire to the input terminal 11 and the output end to the output terminal 12. The conductive pieces 13 at one end of the input terminal 11 and the output terminal 12 are connected to the corresponding conductive layers 31. When the power switch is turned on, the circuit is in a closed state, and the input terminal 11 and the output terminal 12 are in a closed state. When the conductive pieces 13 at one end of the input terminal 11 and the output terminal 12 are not connected to the corresponding conductive layers 31, the input terminal 11 and the output terminal 12 are in an open state. Among them, such as Figures 2-6 As shown, each row of terminal inputs 11 and terminal outputs 12 has the same number and are corresponding left and right, used to connect external wires. Each terminal input 11 and terminal output 12 is electrically connected to a conductive sheet 13. The number of conductive sheets 13 is the same as that of the conductive layer 31. The conductive sheet 13 has a curved structure and includes a vertical part and an inclined part. The vertical part is located on one side of the filter module 3, and the inclined part is located diagonally above the filter module 3. Each conductive sheet 13 has a rubber elastic band 131 sleeved on its outer surface. like Figure 6 As shown, the inner wall of the protective cover 1 is also fixedly provided with a hanger for hanging the elastic band 131. The hanger includes a fixing block 14, a hanging post 141 is fixedly connected to one side of the fixing block 14, and a stop block 142 is fixedly connected to one side of the hanging post 141. One end of the elastic band 131 is sleeved on the outer surface of the vertical conductive sheet 13, and the other end of the elastic band 131 is hung on the hanger. The connection method here is as follows: a small hole is opened at one end of the elastic band 131. The diameter of the small hole is smaller than the diameter of the hanging post 141. Since the elastic band 131 is elastic, it can be hung on the hanging post 141 through the small hole and blocked by the stop block 142. When the input terminal 11 and the output terminal 12 of the terminal are in an open circuit state, that is, when the conductive sheet 13 and the conductive layer 31 are separated from each other, the elastic band 131 is in a slightly stretched state. like Figure 2As shown, the exposed elastic band 131 is not connected to the hanger, while the remaining covered elastic bands 131 are connected to the hanger in a slightly stretched, inclined state. The hanging state of the covered parts is as follows. Figure 6 When the elastic band 131 is connected to the hanger, no terminal of the protective cover 1 comes into contact with the conductive part of the filter module 3, making it easy to detach the filter module 3 from the protective cover 1 without removing the wires on any terminal of the protective cover 1, thus facilitating the maintenance of the filter module 3.

[0017] In this embodiment 1, the bottom end of the filter module 3 is fixedly connected to the base plate 2. The base plate 2 and the protective cover 1 are sealed together and fixed with bolts. The front and rear surfaces of the filter module 3 are engaged with the front and rear inner walls of the protective cover 1, so as to conveniently confine the filter module 3 stably within the protective cover 1. When it is necessary to separate the filter module 3 and the protective cover 1, they can be separated along the docking direction of the two.

[0018] In this embodiment 1, as Figure 2 and Figure 4 As shown, the length of the pressure plate 42 is greater than the maximum distance between multiple conductive layers 31 on any side, and the pressure plate 42 is made of polyethylene, which has excellent insulation effect. Springs are fixedly connected to both sides of the top of each pressure plate 42, and the top of the springs are fixedly connected to the top inner wall of the protective cover 1. The springs restrict the position of the pressure plate 42 to the area directly above the conductive layer 31. The pressure plate 42 is also located at the top of the conductive sheet 13 in a natural or slightly stretched state. By rotating the bolt 4, the pressure plate 42 is moved vertically downwards, causing the pressure plate 42 to simultaneously press down the multiple conductive sheets 13 below. At this time, the conductive sheet 13 is located at the top of the conductive sheet 31. The elastic band 131 on each conductive sheet 13 is gradually stretched until the conductive sheet 13 is firmly pressed into the conductive layer 31. At this time, the terminal input 11 and the terminal output 12 are in a closed circuit state. The length and width of the conductive layer 31 are greater than the length and width of the inclined part of the conductive sheet 13, so it can provide sufficient area for the pressing of the conductive sheet 13. After the pressure plates 42 on both sides press the multiple conductive sheets 13 on both sides into the conductive layer 31, a circuit is formed between the terminal input 11, the conductive sheet 13, the filter module 3 and the terminal output 12. At this time, the filter can be connected and used normally.

[0019] Working principle: When the circuit is broken, the initial shape of the conductive sheet 13 is as follows: Figure 5 As shown in the structure, the elastic band 131 is initially connected at both ends to the conductive sheet 13 and the hanger, respectively, and at this time the elastic band 131 is in a slightly stretched state, as shown in the figure. Figure 6As shown, the conductive sheet 13 is tilted, and neither the tilted nor the vertical portion of the conductive sheet 13 contacts the filter module 3. When using this filter, first rotate the bolt 4 to move the pressure plate 42 downwards vertically, causing the pressure plate 42 to simultaneously press down the multiple conductive sheets 13 below until the conductive sheets 13 are firmly pressed into the conductive layer 31. At this time, the conductive sheets are bent to a certain extent from their initial natural state. At this time, a path is formed between the terminal input 11, the conductive sheet 13, the filter module 3, and the terminal output 12. Then, connect the input and output ends of the wires to the terminal input 11 and the terminal output 12 respectively to form a path. At this time, the filter can be wired and used normally. When the elastic band 131 is under strong tension, and the filter needs maintenance due to malfunction or other reasons, the pressure plate 42 is moved upward by rotating the bolt 4. At this time, the pressure applied to the conductive sheet 13 gradually decreases until it disappears, and the conductive sheet 13 is no longer folded. Since the conductive sheet 13 itself has a certain elasticity as a thin sheet of metal, the conductive sheet 13 gradually returns to its original shape after being depressurized. In conjunction with the gradual decrease of the tensile strength on the elastic band 131, the elastic band 131 eventually returns from the strong tension state to the slight tension state, so that the conductive sheet 13 is far away from the conductive layer 31, thereby disconnecting the wiring terminal of the protective cover 1 from the wiring terminal of the filter module 3. The disassembly effect can be achieved by separating the two along their docking direction.
