Description

Technical Field

[0001] The present application relates to the technical field of matrix optical switching equipment, and in particular to a matrix optical switching equipment. Background Art

[0002] Matrix optical switching equipment primarily includes fiber optic matrix switchers and Xunwei fiber optic matrix switchers. A fiber optic matrix switcher transmits one or more channels of video and audio signals to one or more display devices. For example, if two computer hosts share a single display, a matrix switcher can switch the content from both hosts to the same display or displays.

[0003] When an existing fiber optic matrix switch is in use, the fiber optic matrix switch uses a cooling fan to dissipate heat. When the fan dissipates heat, external humid air can easily enter the fiber optic matrix switch, corroding the components inside the fiber optic matrix switch and reducing the service life of the fiber optic matrix switch.

[0004] Therefore, there is an urgent need for a matrix optical switching device to solve the problem that the internal components of the optical fiber matrix switcher are easily corroded and damaged. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a matrix optical switching device, which has the advantage of increasing the service life of the optical fiber matrix switcher and solving the problem that the internal components of the optical fiber matrix switcher are easily corroded and damaged.

[0006] To achieve the above objectives, the present application provides the following technical solutions: a matrix optical switching device, comprising a fiber optic matrix switcher, an RS-232 serial port, an RJ45 network port, and an optical input (output) interface, wherein the RS-232 serial port, the RJ45 network port, and the optical input (output) interface are arranged on the front of the fiber optic matrix switcher, a heat dissipation and moisture absorption mechanism is arranged on the top of the fiber optic matrix switcher, and a pressing mechanism is arranged on the front of the optical input (output) interface;

[0007] The heat dissipation and moisture absorption mechanism includes a support tube 1, a fan, a drive motor, a connecting rod, a sealing plate, a support tube 2 and a moisture absorption tube. The support tube 1 and the support tube 2 are welded to the top of the optical fiber matrix switcher. The fan is installed in the middle position of the internal frame of the support tube 1. The drive motor is installed on the top wall of the optical fiber matrix switcher. One end of the connecting rod is fixedly connected to the output end of the drive motor. The other end of the connecting rod is welded to the bottom of the sealing plate. The sealing plate is located above the support tube 1. The moisture absorption tube is threadedly connected to the inner side of the support tube 2. The interior of the moisture absorption tube is filled with activated carbon plates.

[0008] The driving motor drives the sealing piece to rotate through the fan to close the top of the support tube, so that the external humid air will not enter the fiber optic matrix switcher. At the same time, the activated carbon plate filled in the moisture absorption tube can absorb the moisture in the air inside the fiber optic matrix switcher, thereby making the inside of the fiber optic matrix switcher drier, preventing humid air from corroding and damaging the internal components of the fiber optic matrix switcher, and improving the service life of the fiber optic matrix switcher.

[0009] Preferably, a pull frame is welded on the top of the moisture absorption cylinder.

[0010] Preferably, the bottom of the moisture absorption cylinder is provided with a plurality of groups of evenly distributed through holes.

[0011] Preferably, the bottom of the second supporting tube is provided with a plurality of groups of circular grooves adapted to the through holes.

[0012] Preferably, the clamping mechanism includes a fixing frame, a pressure plate and screws. The fixing frame is fixed to the front of the optical input (output) interface by screws, and the pressure plate is rotatably connected to the inner side of the fixing frame by a rod. Two groups of screws are inserted on both sides of the pressure plate.

[0013] Preferably, the screw rod passes through the pressing plate and is threadedly connected to the fixing frame.

[0014] In summary, this application has at least one of the following beneficial effects:

[0015] 1. When the fiber optic matrix switch is closed, the drive motor of the matrix optical switching device is started. The drive motor drives the sealing plate to rotate through the fan to close the top of the support tube, so that the external humid air does not enter the fiber optic matrix switch. At the same time, the activated carbon plate filled in the moisture absorption tube can absorb the moisture in the air inside the fiber optic matrix switch, thereby making the inside of the fiber optic matrix switch drier, preventing the humid air from corroding and damaging the internal components of the fiber optic matrix switch, and extending the service life of the fiber optic matrix switch.

[0016] 2. When the plug is inserted into the optical input (output) interface of the matrix optical switching device, the staff can rotate the pressure plate to press the pressure plate against the outside of the plug to fix the plug, making it less likely to shake and preventing the optical input (output) interface from being worn when the plug is pulled, making the fiber optic matrix switcher safer to use.

[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] See also Figure 1-4 A matrix optical switching device includes a fiber optic matrix switcher 1, an RS-232 serial port 2, an RJ45 network port 3 and an optical input (output) interface 4. The RS-232 serial port 2, the RJ45 network port 3 and the optical input (output) interface 4 are arranged on the front of the fiber optic matrix switcher 1. The external optical fiber can be inserted into the optical input (output) interface 4. The upper optical input (output) interface 4 is an optical input interface, and the lower optical input (output) interface 4 is an optical output interface.

A heat dissipation and moisture absorption mechanism is provided on the top of the fiber optic matrix switcher 1, and a pressing mechanism is provided on the front of the optical input (output) interface 4.

[0024] Specifically, the heat dissipation and moisture absorption mechanism includes a support tube 111, a fan 112, a drive motor 113, a connecting rod 114, a sealing plate 115, a support tube 116 and a moisture absorption tube 117. The support tube 111 and the support tube 116 are welded to the top of the optical fiber matrix switcher 1, the fan 112 is installed in the middle position of the internal frame of the support tube 111, the drive motor 113 is installed on the inner top wall of the optical fiber matrix switcher 1, one end of the connecting rod 114 is fixedly connected to the output end of the drive motor 113, and the other end of the connecting rod 114 is welded to the bottom of the sealing plate 115. The sealing plate 115 is located above the support tube 111, the moisture absorption tube 117 is threadedly connected to the inner side of the support tube 116, and the bottom of the support tube 116 is provided with several groups of circular grooves adapted to the through holes 118. A pull frame 119 is welded on the top of the moisture absorption tube 117. The inside of the moisture absorption tube 117 is filled with activated carbon plates, and the bottom of the moisture absorption tube 117 is provided with several groups of evenly distributed through holes 118.

[0025] According to the above technical solution, when the optical fiber matrix switcher 1 is started, the drive motor 113 is started, and the drive motor 113 drives the sealing plate 115 to rotate through the connecting rod 114. When the sealing plate 115 rotates, it deviates from the support tube 111. After the fan 112 is started, the fan 112 dissipates heat from the inside of the optical fiber matrix switcher 1.

[0026] When the fiber optic matrix switcher 1 is closed, the drive motor 113 is started, and the drive motor 113 drives the sealing plate 115 to rotate through the fan 112 to close the top of the support tube 1 11, so that the external humid air will not enter the fiber optic matrix switcher 1. At the same time, the activated carbon plate filled in the moisture absorption tube 117 can absorb the moisture in the air inside the fiber optic matrix switcher 1 through the through hole 118 and the circular groove at the bottom of the support tube 2 116, thereby making the inside of the fiber optic matrix switcher 1 drier, preventing humid air from corroding and damaging the internal components of the fiber optic matrix switcher 1, and improving the service life of the fiber optic matrix switcher 1.

[0027] The staff rotates the pull frame 119, and the pull frame 119 drives the moisture absorption cylinder 117 to rotate, so that the moisture absorption cylinder 117 can be separated from the supporting cylinder 116, which makes it convenient for the staff to replace the moisture absorption cylinder 117.

[0028] Specifically, the clamping mechanism includes a fixed frame 211, a pressure plate 212 and a screw 213. The fixed frame 211 is fixed to the front of the optical input (output) interface 4 by screws. The pressure plate 212 is rotatably connected to the inner side of the fixed frame 211 through a rod. Two sets of screws 213 are inserted on both sides of the pressure plate 212. The screws 213 pass through the pressure plate 212 and are threadedly connected to the fixed frame 211.

[0029] Through the above technical solution, when the plug is inserted into the optical input (output) interface 4, the staff can rotate the pressure plate 212, and the pressure plate 212 is pressed tightly to the outside of the plug. The staff rotates the screw 213, and the screw 213 fixes the pressure plate 212 to the front of the fixed frame 211, thereby fixing the plug, making it less likely to shake, and preventing the optical input (output) interface 4 from being worn when the plug is pulled, making the fiber optic matrix switcher 1 safer to use.

[0030] During use, the driving motor 113 drives the sealing plate 115 to rotate through the fan 112 to close the top of the support tube 111, so that the external humid air will not enter the interior of the optical fiber matrix switcher 1. At the same time, the activated carbon plate filled in the desiccant tube 117 can absorb the moisture in the air inside the optical fiber matrix switcher 1, thereby making the interior of the optical fiber matrix switcher 1 drier, preventing humid air from corroding and damaging the internal components of the optical fiber matrix switcher 1, and improving the service life of the optical fiber matrix switcher 1.
