Description

Technical Field

[0001] The present invention relates to the technical field of communication engineering, and in particular to a signal switching device for communication engineering. Background Art

[0002] Communication engineering is an important branch of electronic engineering and also one of its basic disciplines. This discipline focuses on the principles and applications of information transmission and signal processing in the communication process. Communication engineering studies the transmission of information from the sending end (source) to one or more receiving ends (destination) through electrical pulses in the form of electromagnetic waves, sound waves or light waves. Whether the receiving end can correctly identify the information depends on the level of loss in transmission. Signal processing is an important link in communication engineering, which includes filtering, encoding and decoding. The frequency bands concerned by communication engineering are very wide. The low frequency band, that is, low hertz, is concerned with technical acoustics or low-frequency technology. The high frequency band focuses on microwave or radar systems to visible light laser or laser systems. The frequency bands between microwave and visible light are almost all research objects of communication engineering.

[0003] In the prior art, communication projects often require the use of signal switching equipment, and when using signal switching equipment, it is usually necessary to use multiple connecting cables at the same time. As the placement of the signal switching equipment is not fixed, the connecting cables may bend. At this time, the bent connecting cables are subjected to a force direction different from that of the signal switching equipment, which may cause the connector of the connecting cable and the interface of the signal switching equipment to be in an inclined state. Then, during long-term use, the interface of the signal switching equipment will have an enlarged interface aperture due to the inclined installation of the connector of the connecting cable. At this time, the connector of the connecting cable will become loose at the interface of the signal switching equipment, which may cause the signal transmission of the signal switching equipment to be unstable, thereby affecting its use effect.

[0033] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," etc., etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] like Figures 1 to 4 As shown, a signal switching device for communication engineering includes a signal converter body 1, and the signal converter body 1 is provided with a plurality of mounting seats 2 on the side where the connection port is located. The plurality of mounting seats 2 are grouped into two, and each group of mounting seats 2 corresponds to one of the connection ports; a liftable connecting block assembly 7 is provided in the mounting seat 2, and a pullable first mounting cap assembly 8 is connected to the connecting block assembly 7, one end of the connecting block assembly 7 extends out of the mounting seat 2 and is rotatably connected to a card plate 3, and a part of the connecting block assembly 7 extending out of the mounting seat 2 is also provided with an elastic support assembly, and the elastic support assembly is provided with a movable connecting rod 10, one end of the connecting rod 10 is rotatably connected to the card plate 3, and the elastic support assembly and the connecting rod 10 are used to provide elastic support for the card plate 3.

[0036] The signal adapter device for communication engineering improves the connection installation structure and control method of its card board 3, so that it can better restrain the signal connection line at the connection port of the signal converter body, protect the connection port, and prevent the signal connection line from bending for a long time, which may cause the aperture of the connection port of the signal converter body to become larger and affect the effect of subsequent use. At the same time, it can also clamp and fix the signal connection line, thereby preventing the signal connection line from deforming and bending and affecting the connection stability, so as to avoid adverse effects on the stability and effectiveness of signal transmission.

[0037] The setting of the mounting seat 2 can not only connect the connecting block assembly 7, but also cooperate with the connecting block assembly 7 to install the first mounting cap assembly 8, and the connecting block assembly 7 can be connected and installed with the card plate 3 and the elastic support assembly, so that all components can be installed together on the side of the signal converter body 1 using the mounting seat 2. Through the setting of the upper and lower pairs of mounting seats 2, the card plate 3 is also arranged in pairs up and down, so that the signal connection line at the connection port can be restrained and supported to avoid its bending and unbalanced force on the connection port.

[0038] The first mounting cap assembly 8 can drive the connecting block assembly 7 to move upward by pulling, and can also drive the connecting block assembly 7 to move downward; the up and down movement of the connecting block assembly 7 can increase or decrease the distance between a pair of the card plates 3, so that each pair of card plates 3 can clamp cables with different outer diameters, thereby improving the applicability of the card plates 3.

[0039] The coordinated arrangement of the elastic support assembly and the connecting rod 10 can provide a certain supporting force for the card plate 3, that is, the clamping force of a pair of card plates, so that the pair of card plates 3 can properly clamp the cables to prevent the cables from shaking, loosening or bending.

[0040] Further, combined Figure 5 As shown, a cavity is provided in the mounting seat 2, and a first guide slot 201 is provided on the side wall of the mounting seat 2, and the connecting block assembly 7 extends outward from the first guide slot 201; a first spring 9 is also provided in the mounting seat 2 and is sleeved on the first mounting cap assembly 8, and one end of the first spring 9 abuts against the connecting block assembly 7, and the other end is connected to the ring plate 12 sleeved on the first mounting cap assembly.

[0041] The cavity can accommodate the first connecting post 802 and the guide and limiting post 803 of the first mounting cap assembly 8, as well as the inner connecting portion 701 of the connecting block assembly 7. The first guide slot 201 can provide guidance and limiting functions, allowing the connecting block assembly 7 to move up and down in a predetermined direction. The first spring 9 is disposed within the cavity, and the restoring force of the first spring 9 can be used to return the first mounting cap assembly 8 and the connecting block assembly 7 to their original positions. The ring plate 12 is sleeved over the first connecting post 802 of the first mounting cap assembly and is located at the opening above the cavity. It can limit the guide and limiting post 803 and also connect to the first spring 9.

[0042] Connecting ears are provided on both sides of the mounting base 2 , and the connecting ears are connected to the signal converter body 1 by bolts, so as to facilitate the installation and fixation of the entire mounting base.

[0043] Further, combined Figure 6 As shown, the first mounting cap assembly 8 includes a first connecting column 802, one end of the first connecting column 802 is provided with a pull-out cap head 801, and the other end is provided with an end slide 804, a guide limit column 803 is provided outside the first connecting column 802, and the end slide 804 is slidably connected to the guide limit column 803, and a second spring 805 is provided inside the guide limit column 803 and is sleeved on the first connecting column 802; the guide limit column 803 is arranged in the mounting seat 2 and is connected to the connecting block assembly 7, and the pull-out cap head 801 is located outside the mounting seat 2.

[0044] Through the above arrangement, the pull cap head 801 is located above the mounting seat 2, facilitating pulling the first connecting post 802 from above; the guide limit post 803 is located within the mounting seat 2 and can move up and down relative to the mounting seat 2, thereby driving the connecting block assembly 7 to move together; the second spring 805 within the guide limit post 803 facilitates the reset of the first connecting post 802. Vertical guide grooves 806 are provided on both side walls of the guide limit post 803, and guide protrusions are provided on both sides of the end slide 804. The guide protrusions are connected to the guide grooves 806, so that when the first connecting post 802 is pulled, the first connecting post 802 can move vertically along the guide limit post 803, while compressing the second spring 805. The second spring 805 within the first mounting cap assembly 8 and the first spring 9 disposed externally thereto can form a dual reset function and also have a dual elastic effect.

[0045] During use, the staff pulls the pull-out cap head 801 to move the first connecting column 802 upward, and at the same time squeezes the second spring 805. When the second spring 805 is compressed to the limit state, the entire first mounting cap assembly 8 also moves upward.

[0046] At this time, the movement of the first mounting cap assembly 8 will drive the connecting block assembly 7 to move upward, and then the connecting block assembly 7 will squeeze the first spring 9 inside the mounting seat 2. At the same time, the elastic support assembly will move upward accordingly, and the two adjacent card plates 3 will move away from each other and open. Then the staff can install the external signal conversion line and the connection port of the signal converter body 1;

[0047] After the above steps are completed, loosen the first mounting cap assembly, release the connecting block assembly 7 and the card plate 3, and the connecting block assembly 7 drives the card plate 3 to move downward. At the same time, under the action of the elastic support assembly, the card plate 3 will obtain elastic support, and its inner wall surface will always fit on the outer wall surface of the signal conversion line, thereby fixing its outer wall surface. As a result, the outer wall surface of the signal conversion line is fixed and cannot be bent, thereby achieving the effect of fixing the signal connection line of the signal converter body 1 connection port, preventing it from bending for a long time, which will cause the aperture of the signal converter body 1 connection port to become larger and affect subsequent use.

[0048] Furthermore, the connecting block assembly 7 includes an internal connecting part 701 and an external connecting part 702, the internal connecting part 701 is located in the mounting seat 2 and is connected to the first mounting cap assembly 8, the necked portion 703 of the internal connecting part 701 passes through the mounting seat 2 and is connected to the external connecting part 702, the elastic support assembly is arranged on the external connecting part 702, and a first ear plate 704 is provided on the outer side of the external connecting part 702, and the first ear plate 704 is rotatably connected to the clamping plate 3.

[0049] The connecting block assembly 7 is an integrated structure. Its internal connecting portion 701, located within the mounting base 2, connects to and supports the first mounting cap assembly 8. Its external connecting portion 702, located outside the mounting base 2, connects to and supports the elastic support assembly and rotatably connects to the clamping plate 3. The constricted portion 703 between the internal connecting portion 701 and the external connecting portion 702 can fit through the first guide slot 201 on the side wall of the mounting base. The provision of a pair of first lugs 704 facilitates connection to the clamping plate 3 via a rotating shaft.

[0050] Furthermore, a connecting seat 13 is provided on the clamping plate 3, and the connecting seat 13 is rotatably connected to the connecting block assembly 7 through a rotating shaft or a pin. A second ear plate 25 is also provided on the other side edge of the connecting seat 13, and the second ear plate 25 can also be rotatably connected to the connecting rod 10 through a rotating shaft or a pin.

[0051] Such a setting can allow the card plate 3 to rotate relative to the connecting block assembly 7 under the action of external force, that is, flip the card plate 3, so that the card plate 3 can be stored; the connecting rod 10 can both rotate and slide relatively without affecting the flipping of the card plate 3. When the card plate 3 is in a horizontal state, it can provide supporting force to the card plate under the action of the elastic support assembly.

[0052] Further, combined Figure 7As shown, the elastic support assembly includes an elastic seat 11 arranged on the connecting block assembly 7, a positioning column 14 is provided in the elastic seat 11, a movable receiving block 15 is sleeved on the positioning column 14, and a third spring 16 connected to the receiving block 15, and the receiving block 15 is rotatably connected to the connecting rod 10.

[0053] The side wall of the elastic seat 11 is provided with a second guide slot 1101, the receiving block 15 is slidingly connected to the second guide slot 1101 and one end extends out from the second guide slot 1101, and the extended part is provided with a third ear plate 26, and the third ear plate 26 is rotatably connected to the connecting rod 10.

[0054] Specifically, the elastic seat 11 is fixedly mounted on the top surface of the outer connecting portion 702 of the connecting block assembly 7, the outer circular wall surface of the positioning column 14 is slidably connected to the receiving block 15, the outer circular wall surface of the positioning column 14 movably sleeves the third spring 16, one side of the receiving block 15 is rotatably connected to the connecting rod 10, and one end of the connecting rod 10 is rotatably connected to the clamping plate 3. With this arrangement, the receiving block 15 can move up and down along the second guide slot 1101 and compress the third spring 16 during the movement. The third spring 16 then provides a rebound force to act on the receiving block 15, thereby transmitting the force to the clamping plate 3.

[0055] When the card plate 3 moves downward, the third spring inside the elastic seat will act on the surface of the card plate through the receiving block and the connecting rod; the card plate 3 will bend due to contact with the connecting line, thereby causing the connecting rod 10 to rotate and drive the receiving block 15 to move upward, and then the rebound force of the third spring 16 will mostly act on the surface of the receiving block 15, and then the card plate 3 will be tightly attached to the surface of the connecting line through the rebound force of the third spring 16, so that the connecting line can be clamped and fixed by the coordinated use of multiple groups of card plates 3, thereby preventing it from deforming and bending and affecting the subsequent use of the signal converter body connection port.

[0056] In some embodiments, combined Figure 8 and Figure 9 As shown, a positioning block 24 is provided on the edge of one side of the card plate 3 away from the connecting block assembly 7, and limiting grooves 19 are provided at both ends of the positioning block 24; a pair of positioning seats 17 are provided on both sides above the elastic seat 11 of the elastic support assembly, and the positioning seat 17 is connected to a fourth ear plate 27. After the card plate 3 is flipped over, the positioning block 24 is just located between the pair of fourth ear plates 27, and then the second mounting cap 18 can be used to connect with the fourth ear plate 27 to fix the card plate 3, thereby completing the vertical storage of the card plate 3.

[0057] By adopting the above technical solution, when the staff does not use the card board 3, the staff can rotate the card board 3, and then the positioning block 24 on the top of the card board 3 will move into the area between the pair of fourth ear plates 27. At this time, the limiting block inside the second mounting cap 18 is connected to the positioning block at the fourth ear plate 27 to connect and limit the positioning block 17, so as to facilitate the storage of the card board 3 when it is not in use.

[0058] Specifically, the second mounting cap 18 includes a cap body 1801, a fourth spring 20 is provided in the cap body 1801, and a limit block 21 connected to the fourth spring 20, the limit block 21 is provided with a spherical end 2101, the spherical end 2101 can be retracted into the cap body 1801, and can also pop out from the cap body 1801; limiting grooves 19 are provided on both sides of the positioning block 24, and the spherical end 2101 can pass through the fourth ear plate 27 and enter the interior of the limiting groove 19, and then the rebound force of the fourth spring 20 will cause the limit block 21 to limit and fix the clamping plate 3.

[0059] In some embodiments, combined Figure 1 、 2 As shown in Figure 10, an adjustment component is further provided below the signal converter body 1, and a plurality of positioning connecting plates 23 are respectively provided on both sides of the adjustment component; the adjustment component includes a slide rail 5, and the slide rail 5 is installed on the bottom surface of the signal converter body 1, and a connecting plate 6 is slidably connected below the slide rail 5, and a sliding sleeve 4 is respectively provided at both ends of the connecting plate 6, and the sliding sleeve 4 is adjustably connected to the positioning connecting plate 23; the slide rail 5 is also provided with a plurality of locking connection holes 501 that are locked with the connecting plate 6, so as to fix the slide rail 5 and the positioning connecting plate 23 in an appropriate position.

[0060] Further, combined Figure 11 and Figure 12 As shown, the connecting plate 6 is provided with a snap-in groove 601, and the snap-in groove 601 is connected to the slide rail 5, and is connected to the locking connection hole 501 by a bolt at the snap-in groove 601, and the sliding sleeve 4 is also connected to the connecting plate 6 by a bolt; the side of the sliding sleeve 4 is provided with a vertical protrusion, and the side wall of the positioning connecting plate 23 is provided with a vertical groove connected to the vertical protrusion to slideably connect the positioning connecting plate 23, and the upper edge of the sliding sleeve 4 is rotatably connected to the adjusting bolt 22, and the adjusting bolt 22 is threadedly connected to the positioning connecting plate 23.

[0061] When the signal converter body 1 is installed, the staff can slide the connecting plate 6 on the surface of the slide rail 5, and then multiple positioning connecting plates 23 will move with the movement of the connecting plate 6. Then the positioning connecting plates 23 can change their positions, making it easier to connect and fix them with mounting plates of different sizes, thereby achieving the effect of facilitating the installation of the signal converter body 1 on different mounting plates.

[0062] The two ends of the two connecting plates 6 are slidably connected with a sliding sleeve 4, and one side of the sliding sleeve 4 is slidably connected to the positioning connecting plate 23. The sliding sleeve 4 is threadedly connected to the connecting plate 6 by a bolt. The staff can slide the sliding sleeve 4 on the surface of the connecting plate 6 by removing the bolt at the bottom of the sliding sleeve 4, and then the positioning connecting plate 23 will move accordingly, so as to facilitate the adjustment of the longitudinal use position of the positioning connecting plate 23. The top surface of the sliding sleeve 4 is rotatably connected with the adjusting bolt 22, and the adjusting bolt 22 is threadedly connected to the positioning connecting plate 23. When the height of the mounting plate is uneven, the staff can rotate the adjusting bolt 22, and then the positioning connecting plate 23 will move up or down under the threaded transmission action of the adjusting bolt 22 and the positioning connecting plate 23, so as to facilitate the individual adjustment of the use height of multiple positioning connecting plates 23, so as to improve its adaptability during installation.

[0063] Preferably, the inner arc wall surfaces of several of the card plates 3 are provided with anti-skid pads. By adopting the above technical solution, the card plates are prevented from sliding when in use.

[0064] Preferably, the surfaces of the plurality of positioning connecting plates 23 are coated with a corrosion-resistant coating. By adopting the above technical solution, the service life of the positioning connecting plates can be improved.

[0065] One working mode of the signal switching equipment used in this communication project is: Please refer to Figures 1-12As shown, when in use, the staff installs the signal converter body 1 through the multiple positioning connecting plates 23. During this process, the staff can adjust the use position of the positioning connecting plate 23 through the adjustment component, so that it can be suitable for installation plates of different sizes, and then the staff can connect the connecting line of the external signal conversion to the connection port of the signal converter body 1. During this process, the staff pulls the multiple first connecting columns 802, and the upward movement of the first connecting column 802 will squeeze the second spring 805, and then when the second spring 805 is compressed to the limit state, the first mounting cap assembly 8 will move upward accordingly.
