Description

Technical Field

[0001] This invention relates to the field of optical switch technology, specifically to an optical switch device for cross-connection equipment. Background Technology

[0002] Optical cross-connect equipment is a core node device in optical transport networks. It is a multifunctional OTN transmission device that combines multiplexing, optical cross-connection, protection / recovery, monitoring and network management. Various types of optical switch matrices are used to realize spatial switching, which complete the cross-connection function from the input end to the output end in the spatial domain.

[0003] An optical switch is an optical device with one or more optional transmission ports. Its function is to physically switch or logically operate optical signals in optical transmission lines or integrated optical circuits. In fiber optic transmission systems, optical switches are used for switching between multiple monitors, LANs, multiple light sources, detectors, and protection Ethernet.

[0004] Current optical switching devices are relatively complicated in terms of switching the output port. The main technical solution is that mechanical optical switches use miniature relays to drive prisms or reflectors to switch the optical path. Most existing optical switching devices use screws to fix the sealing cover, which makes maintenance difficult. Moreover, most of the output wires of existing optical switches are fixed connections, making them difficult to replace.

[0005] To address the aforementioned problems, the inventors propose an optical switching device for cross-connection equipment. Summary of the Invention

[0006] To address the issues of cumbersome output port switching and complicated maintenance of optical switches, the present invention aims to provide an optical switch device for cross-connection equipment.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: It includes a housing, a sliding mounting plate fixedly connected to the bottom of the inner surface of the housing, a reflector groove formed on the top of the sliding mounting plate, a reflector slidably connected to the inner surface of the reflector groove via a slider, a motor groove formed on the top of the sliding mounting plate, a motor slidably connected to the inner surface of the motor groove via a slider, the outer surface of the motor being fixedly connected to one side of the reflector, an output port groove formed on the top of the sliding mounting plate, an output mounting plate slidably connected to the inner surface of the output port groove via a slider, and one side of the output mounting plate being fixedly connected to the outer surface of the reflector via a connecting rod. An output port is provided on one side of the plate. A toothed rack is fixedly connected to the bottom of the inner surface of the housing. A rotating gear adapted to the toothed rack is fixedly connected to one end of the motor output shaft. A sealing cover is provided on the top of the housing. A conductive mechanism is provided on one side of the housing. Several conductive mechanisms are provided. A filter mechanism is provided on the top of the sealing cover. The housing and the sealing cover are connected by a disassembly mechanism. By setting the motor, starting the motor drives the reflector to move the output port, thereby changing the position of the output port, and thus achieving the purpose of arbitrarily switching the output port. This increases the flexibility of the reflected light signal output, makes the switching of the output port of the optical switch more convenient, and improves the working efficiency.

[0008] Preferably, the conductive mechanism includes a conductive barrel, one end of which is fixedly connected to the inner surface of the housing, and the other end of which is provided with an input port. A first conductive plate is slidably connected to the inner surface of the conductive barrel, and a conductive rod is fixedly connected to one side of the first conductive plate. The conductive barrel is made of copper and is used to install the input port and the first conductive plate. The first conductive plate is used to connect the conductive rod, and the conductive rod is electrically connected to an output wire through a second conductive plate. One end of the conductive rod penetrates the housing and extends to the outside of the housing. An insulating spring is sleeved on the outer surface of the conductive rod, and the other end of the conductive rod is fixedly connected to a second conductive plate. An insulating barrel is fixedly connected to one side of the housing, and an output wire is provided on one side of the insulating barrel. One end of the output wire is connected to the outer surface of the second conductive plate. The conductive rod and the second conductive plate are in close contact with the output wire, and the elastic force of the insulating spring causes the conductive rod to drive the second conductive plate to make close contact with one end of the output wire, increasing the stability of the connection. The second conductive plate is used for electrical connection with the output wire. A conductive copper plate can be set at one end of the output wire to increase the stability of the device connection. A limit spring plate is fixedly connected to the outer surface of the insulating barrel. A limit spring rod is slidably connected through the outer surface of the limit spring plate. A limit spring is sleeved on the outer surface of the limit spring rod. A limit pin barrel that matches the limit spring rod is fixedly connected to the outer surface of the output wire. By setting the limit spring rod, moving the limit spring rod away from the limit pin barrel will contact the limit of the output wire. Moving the output wire away from the insulating barrel will allow the output wire to be disassembled. The operation is simple and convenient, making it easy to maintain and replace the output wire.

[0009] Preferably, the filtering mechanism includes a filter frame, the bottom of which is in close contact with the top of the sealing cover. A filter threaded rod is fixedly connected to the top of the sealing cover. Four filter threaded rods are provided, one end of which passes through the filter frame and extends to the outside of the filter frame. The filter frame is used to install the filter screen, and the filter threaded rod is used to limit the filter frame, making it easy to disassemble and clean or replace the filter screen inside. A filter threaded cap is threaded onto the outer surface of the filter threaded rod. Filter air inlets are provided on both sides of the filter frame, and filter screens are fixedly connected to both sides of the inner surface of the filter frame. The filter threaded cap is used to compress the filter frame, thereby fixing it and ensuring its stability. The filter air inlets are used for air intake, and the filter screens are used to filter dust from the air.

[0010] Preferably, a baffle is fixedly connected to the inner surface of the housing, and a partition is fixedly connected to the top of the baffle. There are four partitions. A cooling pipe is fixedly connected through one side of the partition. The baffle is used to install the partition. Cooling water can be placed between two adjacent partitions to increase the cooling effect of the device. The cooling pipe cools the air. One end of the cooling pipe passes through the baffle and extends to the bottom of the baffle. Cooling fins are fixedly installed on both sides of the bottom of the sealing cover by opening slots. An air inlet slot is opened on the top of the sealing cover. The cooling fins reduce the temperature of the cooling water, thereby reducing the stability of the air in the cooling pipe.

[0011] Preferably, the disassembly mechanism includes a disassembly plate, with the bottom of the sealing cover fixedly connected to the top of the disassembly plate. Both sides of the top of the housing are provided with disassembly grooves adapted to the disassembly plate. A disassembly ejector plate is slidably connected to the inner surface of the disassembly groove. The disassembly plate is inserted into the disassembly groove to install the sealing cover. This operation is simple and convenient, facilitating the installation and disassembly of the sealing cover. The disassembly ejector plate allows the disassembly plate to easily eject from the disassembly groove, facilitating the disassembly plate's removal and saving labor. A disassembly ejector spring is fixedly connected to the inner surface of the disassembly groove, with one end of the spring fixedly connected to the bottom of the disassembly ejector plate. A disassembly pin is slidably connected through one side of the housing, with a disassembly spring sleeved on the outer surface of the pin. A disassembly spring hole adapted to the disassembly pin is provided on one side of the disassembly plate. By setting the disassembly plate, moving the disassembly pin releases the restriction on the disassembly plate, moving the sealing cover and causing the disassembly plate to move away from the disassembly groove, thereby removing the sealing cover. This operation is simple and convenient, saving labor.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. By setting up the motor, starting the motor drives the reflector to move the output port, thereby changing the position of the output port and achieving the purpose of arbitrarily switching the output port. This increases the flexibility of the reflected light signal output, makes the switching of the output port of the optical switch more convenient, and improves work efficiency.

[0014] 2. By setting up the disassembly plate, the disassembly pin is moved to release the limit on the disassembly plate, and the sealing cover is moved to drive the disassembly plate away from the disassembly groove, thereby disassembling the sealing cover. The operation is simple and convenient, saving a certain amount of labor.

[0015] 3. By setting the limit spring rod, moving the limit spring rod away from the limit pin barrel will contact the limit of the output wire, move the output wire away from the insulation barrel, and thus disassemble the output wire. The operation is simple and convenient, making it easy to repair and replace the output wire. Attached Figure Description

One side of the output mounting plate 8 is fixedly connected to the outer surface of the reflector 4 via a connecting rod. An output terminal is provided on one side of the output mounting plate 8. A toothed rack 10 is fixedly connected to the bottom of the inner surface of the housing 1. A rotating gear 11 that matches the toothed rack 10 is fixedly connected to one end of the output shaft of the motor 6. A sealing cover 12 is provided on the top of the housing 1. A conductive mechanism 120 is provided on one side of the housing 1. Several conductive mechanisms 120 are provided. A filter mechanism 130 is provided on the top of the sealing cover 12. The housing 1 and the sealing cover 12 are connected by a disassembly mechanism 140. By setting the motor 6, starting the motor 6 drives the reflector 4 to move the output port 9, thereby changing the position of the output port 9, and thus achieving the purpose of arbitrarily switching the output port 9. This increases the flexibility of the reflected light signal output, makes the switching of the output port 9 of the optical switch more convenient, and improves the working efficiency.

[0032] The conductive mechanism 120 includes a conductive barrel 121. One end of the conductive barrel 121 is fixedly connected to the inner surface of the housing 1. The other end of the conductive barrel 121 is provided with an input port 122. A first conductive sheet 123 is slidably connected to the inner surface of the conductive barrel 121. A conductive rod 124 is fixedly connected to one side of the first conductive sheet 123.

[0033] By adopting the above technical solution, the conductive barrel 121 is made of copper. The conductive barrel 121 is used to install the input port 122 and the first conductive plate 123. The first conductive plate 123 is used to connect the conductive rod 124. The conductive rod 124 is electrically connected to the output wire 128 through the second conductive plate 126.

[0034] One end of the conductive rod 124 passes through the housing 1 and extends to the outside of the housing 1. An insulating spring 125 is sleeved on the outer surface of the conductive rod 124. The other end of the conductive rod 124 is fixedly connected to a second conductive sheet 126. An insulating barrel 127 is fixedly connected to one side of the housing 1. An output wire 128 is provided on one side of the insulating barrel 127. One end of the output wire 128 is in close contact with the outer surface of the second conductive sheet 126.

[0035] By adopting the above technical solution, the elastic force of the insulating spring 125 causes the conductive rod 124 to drive the second conductive piece 126 to make close contact with one end of the output wire 128, thereby increasing the stability of the connection. The second conductive piece 126 is used to electrically connect with the output wire 128, and a conductive copper piece can be provided at one end of the output wire 128 to increase the stability of the device connection.

[0036] A limiting spring plate 129 is fixedly connected to the outer surface of the insulating barrel 127. A limiting spring rod 1210 is slidably connected through the outer surface of the limiting spring plate 129. A limiting spring 1211 is sleeved on the outer surface of the limiting spring rod 1210. A limiting pin barrel 1212 that is compatible with the limiting spring rod 1210 is fixedly connected to the outer surface of the output wire 128.

[0037] By adopting the above technical solution, the limiting spring rod 1210 is moved away from the limiting pin barrel 1212, thereby contacting the limiting of the output wire 128, moving the output wire 128 away from the insulating barrel 127, thereby disassembling the output wire 128. The operation is simple and convenient, making it easy to maintain and replace the output wire 128.

[0038] The filter mechanism 130 includes a filter frame 131. The bottom of the filter frame 131 is in close contact with the top of the sealing cover 12. A filter threaded rod 132 is fixedly connected to the top of the sealing cover 12. There are four filter threaded rods 132. One end of the filter threaded rod 132 passes through the filter frame 131 and extends to the outside of the filter frame 131.

[0039] By adopting the above technical solution, the filter frame 131 is used to install the filter screen 135, and the filter threaded rod 132 is used to limit the filter frame 131, so that the filter frame 131 can be easily disassembled, thereby facilitating the cleaning and replacement of the filter screen 135 inside the filter frame 131.

[0040] The outer surface of the filter threaded rod 132 is threaded with a filter threaded cap 133, and both sides of the filter frame 131 are provided with filter air inlets 134. Both sides of the inner surface of the filter frame 131 are fixedly connected with filter screens 135.

[0041] By adopting the above technical solution, the filter thread cap 133 is used to squeeze the filter frame 131, thereby fixing the filter frame 131 and ensuring the stability of the filter frame 131. The filter air inlet 134 is used for air intake, and the filter screen 135 is used for filtering dust in the air.

[0042] A baffle 13 is fixedly connected to the inner surface of the housing 1, and a partition 14 is fixedly connected to the top of the baffle 13. There are four partitions 14, and a cooling pipe 15 is fixedly connected through one side of the partition 14.

[0043] By adopting the above technical solution, the baffle 13 is used to install the partition 14, and cooling water can be placed between two adjacent partitions 14 to increase the cooling effect of the device, and the cooling pipe 15 cools the air.

[0044] One end of the cooling pipe 15 passes through the baffle 13 and extends to the bottom of the baffle 13. Cooling plates 16 are fixedly installed on both sides of the bottom of the sealing cover 12 by opening slots. An air inlet slot 17 is opened on the top of the sealing cover 12.

[0045] By adopting the above technical solution, the cooling element 16 reduces the temperature of the cooling water, thereby reducing the stability of the air inside the cooling pipe 15.

[0046] The disassembly mechanism 140 includes a disassembly plate 141. The bottom of the sealing cover 12 is fixedly connected to the top of the disassembly plate 141. Both sides of the top of the housing 1 are provided with disassembly grooves 142 that are adapted to the disassembly plate 141. A disassembly ejector plate 143 is slidably connected to the inner surface of the disassembly groove 142.

[0047] By adopting the above technical solution, the disassembly plate 141 is inserted into the disassembly groove 142 to install the sealing cover 12. The operation is simple and convenient, and it is convenient to install and disassemble the sealing cover 12. The disassembly pop-out plate 143 makes it easy for the disassembly plate 141 to pop out of the disassembly groove 142, which facilitates the disassembly of the disassembly plate 141 and saves a certain amount of labor.

[0048] A disassembly spring 144 is fixedly connected to the inner surface of the disassembly groove 142. One end of the disassembly spring 144 is fixedly connected to the bottom of the disassembly plate 143. A disassembly pin 145 is slidably connected through one side of the housing 1. A disassembly spring 146 is sleeved on the outer surface of the disassembly pin 145. A disassembly spring hole 147 that matches the disassembly pin 145 is opened on one side of the disassembly plate 141.

[0049] By adopting the above technical solution, the disassembly plate 141 is set, the disassembly pin 145 is moved to release the limitation on the disassembly plate 141, and the sealing cover 12 is moved to drive the disassembly plate 141 away from the disassembly groove 142, thereby disassembling the sealing cover 12. The operation is simple and convenient, and saves a certain amount of labor.

[0050] Working principle: When it is necessary to switch the output port 9, the motor 6 is started to drive the rotating gear 11 to rotate. Due to the setting of the toothed rack 10, the rotation of the rotating gear 11 drives the motor 6 to move the reflector 4 along the reflector slide groove 3. The reflector 4 drives the output mounting plate 8 to move the output port 9. The output port 9 emits an incident light signal into the reflector 4. After refraction by the reflector 4, the reflected light signal enters the input port 122. The input port 122 receives the signal and outputs it through the conductive barrel 121, the first conductive sheet 123, the conductive rod 124, the second conductive sheet 126 and the output wire 128. When it is necessary to replace the output wire 128, the moving limit spring rod 1210 drives the limit spring 1211 to extend. The limit spring rod 1210 moves away from the limit pin barrel 1212, thereby releasing the limit on the output wire 128. The output wire 128 is moved away from the insulating barrel 127, thereby disassembling and replacing the output wire 128.

[0051] When the optical switch needs to be repaired, the disassembly pin 145 is moved to extend the disassembly spring 146, and the disassembly pin 145 is moved away from the disassembly spring hole 147, thereby releasing the limit on the disassembly plate 141. The sealing cover 12 is moved to drive the disassembly plate 141 away from the disassembly groove 142, thereby removing the sealing cover 12, which facilitates the repair of the optical switch.

[0052] When heat dissipation is required for the optical switch, outside air enters the filter frame 131 through the filter inlet 134. Due to the filter screen 135, dust in the air is filtered out. The clean air enters the interior of the housing 1 through the air inlet slot 17 and the cooling pipe 15, thereby exchanging with the hot air inside the housing 1 to dissipate heat from the optical switch. The cooling chip 16 is activated to cool the cooling water between the two adjacent partitions 14. When the air passes through the cooling pipe 15, the cooling water cools the air inside the cooling pipe 15, increasing the heat dissipation effect of the device.

[0053] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
