Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a frequency hopping filter. Background Art

[0002] A frequency hopping filter is a filter used to process frequency-hopping signals. In frequency-hopping communication, the signal frequency jumps between different frequencies in a specific sequence to enhance communication security and interference immunity. The primary function of a frequency-hopping filter is to selectively filter out signals outside a specific frequency band, thereby preserving the characteristics of the target frequency-hopping signal. This can be achieved through a series of filters, such as bandpass filters, bandstop filters, or other techniques. Frequency-hopping filters play a vital role in frequency-hopping communication systems, helping the system maintain signal clarity and reliability during frequency hopping.

[0003] When using existing filters, the connecting piece is generally directly put on the connection terminal of the filter and then the nut is screwed to connect. This connection method requires the nut to be completely unscrewed before installation, which requires multiple steps and is very inconvenient. At the same time, due to the relatively small specifications of the nut, the nut is very easy to be lost after being taken out during actual operation, affecting the later installation of the entire device.

[0004] Therefore, it is necessary to provide a new frequency hopping filter to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a frequency hopping filter.

[0006] The frequency hopping filter provided by the utility model comprises: a filter body, wherein both ends of the filter body are provided with a plurality of connection terminals, and the outside of the connection terminals is provided with a fixing component;

[0007] The fixing assembly includes an insertion rod, two of which are symmetrically distributed on both sides of the outside of the corresponding terminal. The insertion rod and the corresponding terminal are covered with the same slidingly connected extrusion piece. A fixedly connected sleeve is provided at the center of the outer wall of the extrusion piece. The inner wall of the sleeve is slidably connected to the outer wall of the terminal. A limiting cap is provided at the end of the insertion rod, and a spring is provided between the limiting cap and the extrusion piece.

[0008] Preferably, both ends of the filter body are provided with fixedly connected fixing frames, the side walls of the fixing frames corresponding to the connection terminals are provided with card slots, and the outside of the fixing frames is provided with a slidably connected protective cover.

[0009] Preferably, a base plate is provided at the bottom of the filter body, and rotating rods with rotatable connections are mounted on both sides of the top of the base plate. Both sides of the outer wall of one rotating rod are threadedly connected to the protective cover through a threaded structure, and the outer wall of the other rotating rod is slidably connected to the protective cover.

[0010] Preferably, a gripping tube is sleeved at the center of the outer wall of the rotating rod threadably connected to the protective cover, and the thread directions of the thread structures on both sides are opposite.

[0011] Preferably, a positioning groove is provided at a portion of the side wall of the protective cover opposite to the card slot, the card slot and the inner wall of the positioning groove are both inlaid with rubber half rings, and a transparent plate is provided on the side of the protective cover away from the card slot.

[0012] Preferably, the length of the sleeve is greater than the length of the terminal.

[0013] Preferably, one end of the spring is fixedly connected to the limiting cap, and the other end of the spring is fixedly connected to the extrusion sheet.

[0014] Compared with related technologies, the frequency hopping filter provided by the present invention has the following beneficial effects:

[0015] The utility model adopts the setting of the fixing component. When the device is connected to the connecting line, the spring can drive the extrusion piece to reset through its own force. When the extrusion piece squeezes the wiring piece at the end of the connecting line, the connection of the connecting line can be quickly completed.

[0016] The utility model fixes the connecting wire by means of clamping and extrusion, which can avoid the phenomenon of the fixing parts falling off and being lost during the later use process, thereby making the later installation and connection operation of the device more convenient.

[0017] The utility model provides a protective cover, and after the connection between the filter body and the connecting line is completed, the protective cover can be smoothly mounted on the connecting portion of the two, thereby smoothly protecting the connecting portion. At the same time, through the extrusion of the transparent plate on the inner wall of the protective cover and the sleeve, the phenomenon of random shaking of the extrusion piece during use can be avoided, thereby improving the connection stability during the later use of the device.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0025] See also Figures 1 to 4 An embodiment of the present invention provides a frequency hopping filter, which includes: a filter body 1.

[0026] In the embodiments of the present invention, please refer to Figure 1 、 Figure 2 and Figure 3 , a plurality of connection terminals 11 are provided at both ends of the filter body 1, and a fixing component 2 is provided outside the connection terminal 11;

[0027] The fixing assembly 2 includes an insertion rod 21, which is provided with two insertion rods 21 and symmetrically distributed on both sides of the outside of the corresponding terminal 11. The insertion rod 21 and the corresponding terminal 11 are externally sleeved with the same slidingly connected extrusion piece 22, and a fixedly connected sleeve 23 is provided in the center of the outer wall of the extrusion piece 22. The inner wall of the sleeve 23 is slidably connected to the outer wall of the terminal 11. A limiting cap 211 is provided at the end of the insertion rod 21, and a spring 212 is arranged between the limiting cap 211 and the extrusion piece 22. One end of the spring 212 is fixedly connected to the limiting cap 211, and the other end of the spring 212 is fixedly connected to the extrusion piece 22.

[0028] It should be noted that: through the setting of the fixing component 2, when the connecting wire is installed later, the staff can directly hold the sleeve 23 and pull the extrusion piece 22 out from the outside of the terminal 11 after removing the protective cover 4, and then the wiring piece at the end of the connecting wire can be placed outside the terminal 11 and the grip of the sleeve 23 can be released. At this time, the spring 212 can drive the extrusion piece 22 to reset through its own force. When the extrusion piece 22 squeezes the wiring piece at the end of the connecting wire, the connection of the connecting wire can be quickly completed.

[0029] By fixing the connecting wires in a clamping and extruding manner, the fixing parts can be prevented from falling off and being lost during later use, thereby making the later installation and connection operations of the device more convenient.

[0030] In the embodiments of the present invention, please refer to Figure 1 、 Figure 3 and Figure 4 , both ends of the filter body 1 are provided with a fixed frame 3 with a fixed connection, and the side walls of the fixed frame 3 are provided with a card slot 31 at the corresponding parts of the wiring terminal 11, and a slidingly connected protective cover 4 is provided on the outside of the fixed frame 3. The bottom of the filter body 1 is provided with a base plate 12, and both sides of the top of the base plate 12 are provided with a rotatably connected rotating rod 5. Both sides of the outer wall of one rotating rod 5 are threadedly connected to the protective cover 4 through a threaded structure, and the outer wall of the other rotating rod 5 is slidably connected to the protective cover 4. A holding tube 51 is provided in the center of the outer wall of the rotating rod 5 threadedly connected to the protective cover 4, and the thread directions of the threaded structures on both sides are opposite. A positioning groove 41 is provided on the side wall of the protective cover 4 corresponding to the card slot 31, and the inner walls of the card slot 31 and the positioning groove 41 are inlaid with rubber half rings, and a transparent plate 42 is provided on the side of the protective cover 4 away from the card slot 31. The length of the sleeve 23 is greater than the length of the wiring terminal 11.

[0031] It should be noted that after the connection between the filter body 1 and the connecting wire is completed, the protective cover 4 can be smoothly mounted on the connecting portion between the terminal 11 and the connecting wire, thereby smoothly protecting the connecting portion.

[0032] By arranging a rubber half ring inside the card slot 31 and the positioning slot 41, when the protective cover 4 and the fixed frame 3 are in contact with each other, the rubber half ring can smoothly contact the outer wall of the connecting wire, thereby smoothly filling the connection between the connecting wire and the card slot 31 and the positioning slot 41, thereby improving the sealing effect of the connection between the fixed frame 3 and the protective cover in the later stage.

[0033] At the same time, by providing a relatively long sleeve 23, when the spring 212 drives the extrusion piece 22 to abut against the connecting piece on the connecting line, when the protective cover 4 is put on, the transparent plate 42 on the inner wall of the protective cover 4 can be smoothly squeezed with the sleeve 23, thereby avoiding the phenomenon of random shaking of the extrusion piece 22 during use, thereby improving the connection stability during the later use of the device;

[0034] By setting the transparent plate 42, when installing or removing the connecting wires later, the staff can easily view the position of the connecting wires from both sides, reducing the obstruction of the connecting wires and the connection parts of the terminal blocks 11, thereby avoiding the staff from connecting the connecting wires.

[0035] The working principle of the frequency hopping filter provided by the utility model is as follows:

[0036] Later in the use of this device, when it is necessary to install the FM filter, first, the bottom plate 12 can be connected to the desired position by bolts, and the filter body 1 can be installed in the desired position. Then, the gripping tube 51 can be gripped and the corresponding rotating rod 5 can be controlled to rotate. At this time, the rotating rod 5 can drive the protective covers 4 on both sides to move through the threaded structure. Since the thread directions of the two sides of the rotating rod 5 connected to the protective covers 4 are opposite, the protective covers 4 on both sides can be smoothly moved away from each other, and then the protective covers 4 can be smoothly moved out from the outside of the terminal 11 and unfolded.

[0037] At this time, the staff can pick up the connecting wire to be used with one hand and hold the sleeve 23 with the other hand to make the sleeve 23 slide smoothly on the outside of the insertion rod 21 until the extrusion piece 22 falls off from the outside of the terminal 11. Then, the connecting piece at the end of the connecting wire can be smoothly sleeved on the outside of the terminal 11. At this time, the staff can release the grip of the sleeve 23. At this time, the spring 212 can smoothly drive the extrusion piece 22 to reset through its own force, so that the extrusion piece 22 squeezes and fixes the connecting piece at the end of the connecting wire, and then the connecting wire can be smoothly clamped in the card slot 31.

[0038] After completing the fixation of the connecting line, the rotating rod 5 can be controlled to rotate in the reverse direction, so that it drives the protective covers 4 on both sides to move relative to each other through the threaded structure, until the positioning groove 41 on the side wall of the protective cover 4 smoothly abuts against the outer wall of the connecting line, and the connecting line can be smoothly fixed for a second time. The transparent plate 42 on the side wall of the protective cover 4 abuts against the end of the grip tube, and the grip tube can be smoothly limited, thereby avoiding the phenomenon that the grip tube drives the extrusion piece 22 to move randomly during use. Therefore, the connection of the wiring part of the filter body 1 can be more stable during the later use, and the filter body 1 can be smoothly used.

[0039] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0040] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
