Description

[Technical field]

[0001] The present invention relates to an optical module assembly, and more particularly to an optical module assembly that enables an optical module to be disconnected without separating the optical module from an optical cable, thereby preventing contamination or damage to an optical cable connection portion due to separation of the optical cable. [Background technology]

[0002] Generally, an optical module is a module that contains various optical communication functions in one package and can be connected to optical fiber. Recently, bidirectional optical modules that integrate an optical transmitter using a laser diode as a light source, which consumes little power and can be used over long distances, and an optical receiver that uses a photodiode for optical communication, are mainly used.

[0003] A bidirectional optical module basically includes an optical transmitter, an optical receiver, an optical filter, a connector, etc. Also, an isolator is installed to prevent reflection noise from affecting the characteristics of the laser diode.

[0004] Among them, the connector is optically coupled by inserting an external optical cable. However, since the connector is made of metal, it is difficult for external electrochemical There is a problem that electrostatic discharge (ESD) can flow through the connector and affect elements (e.g., the laser diode of the optical transmitter) inside the optical module.

[0005] In addition, optical fibers are made of glass fibers the thickness of a human hair, making them physically very fragile. In particular, the connection points of optical cables, where the optical fiber is exposed, are extremely vulnerable to vibrations and shocks.

[0006] Conventionally, in order to disconnect an optical module, the optical module and the optical cable are separated, which causes a problem that the connection part of the separated optical cable is exposed to the surrounding environment and is contaminated by surrounding foreign objects or is damaged by external impact. Summary of the Invention [Problem to be solved by the invention]

[0007] The problem that the present invention aims to solve is to provide an optical module assembly that enables the optical module to be disconnected without separating the optical cable, thereby preventing contamination or damage to the optical cable connection due to separation of the optical cable. [Means for solving the problem]

[0008] The above problem is solved by an optical module assembly including: an optical module body having an optical transceiver built therein; a first connector coupled to one side of the optical module body so as to be connected to the optical transceiver inside the optical module body; a second connector having an insertion hole formed therein for inserting an optical cable, the optical cable being inserted into the insertion hole and connected to the first connector to connect the optical cable to the optical transceiver connected to the first connector; and a disconnection unit provided on the first connector and the second connector, for disconnecting the connection between the first connector and the second connector by rotating.

[0009] The present invention further includes an engaging means formed on the optical cable, a coupling / engagement groove formed on the first connector and into which the engaging means is inserted, and a release / engagement groove formed on the second connector and into which the engaging means is inserted, wherein the engaging means of the optical cable is inserted into the coupling / engagement groove of the first connector when the first connector and the second connector are connected, and is inserted into the release / engagement groove of the second connector when the first connector and the second connector are disconnected.

[0010] Here, the engagement means of the optical cable comprises a coupling belt protruding from the outside of the optical cable and a coupling block extending on the side of the coupling belt, the coupling belt being formed so as to be freely movable toward the optical cable, and when the coupling belt moves toward the optical cable, the coupling block is positioned adjacent to the optical cable.

[0011] The present invention also includes a guide groove formed in the first connector, and a guide formed in the second connector, inserted into the guide groove, and sliding along the guide groove, wherein the second connector slides by movement of the guide to be connected to or disconnected from the first connector.

[0012] Meanwhile, the disconnecting unit includes a first rotating protrusion protruding from the first connector, a rotating link having one side rotatably connected to the first rotating protrusion and rotating around the first rotating protrusion, and a second rotating protrusion protruding from the guide of the second connector and having the other side of the rotating link rotatably connected to the second connector.

[0013] Here, the present invention further includes a coupling hole formed on the other side of the rotating link so that the second rotating protrusion can be inserted therein, and the coupling hole is formed to have a width larger than that of the second rotating protrusion.

[0014] The present invention also includes a fixed block that is slidably mounted on the first connector and has a portion thereof clamped and fixed in the optical module main body by the sliding movement, and a fixed rod that extends from one end of the rotating link and has a portion thereof engaged with the fixed block.

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an optical module assembly according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

[0024] As shown in Figures 1 to 5, the optical module assembly according to the present invention includes an optical module body 10 having an optical transceiver (not shown) built therein, a first connector 100 coupled to one side of the optical module body 10 to be connected to the optical transceiver inside the optical module body 10, a second connector 200 having an insertion hole formed therein into which an optical cable 300 is inserted, the optical cable 300 being inserted into the insertion hole to be connected to the first connector 100 and connecting the optical cable 300 to the optical transceiver connected to the first connector 100, and a disconnection unit 400 provided on the first connector 100 and the second connector 200 and rotating to disconnect the first connector 100 and the second connector 200.

[0025] First, the optical module body 10 is a general optical module having an optical transceiver and an optical filter built therein. The optical module body 10 converts an electrical signal into an optical signal and converts an optical signal into an electrical signal between an optical cable connecting an optical communication network and a transmission device in charge of data transmission. The optical module body 10 is a well-known technology that has been widely used in the past, so a detailed description will be omitted.

[0026] The first connector 100 is a member formed in an approximately rectangular box shape and is fixedly coupled to one side of the optical module body 10. At this time, the first connector 100 is provided to be coupled to an optical transceiver (not shown) inside the optical module body 10, and a connection terminal (not shown) to be coupled to the optical transceiver is built in the first connector 100. The connection terminal is coupled to a connection terminal of an optical cable 300 described later, so that the optical cable 300 and the optical module body 10 are coupled to each other. In addition, guide grooves 120 into which guides 220 of a second connector 200 described later are inserted are formed on both sides of the first connector 100. In this embodiment, the first connector 100 is described as a member formed in an approximately rectangular box shape, but is not necessarily limited thereto and includes various shapes.

[0027] Meanwhile, the second connector 200 is a member formed in an approximately rectangular box shape to correspond to the first connector 100, and is provided to be connected to the first connector 100. The second connector 200 has an insertion hole into which the optical cable 300 is inserted, and the optical cable 300 is inserted into the insertion hole. At this time, a connection terminal of the optical cable 300 is inserted into a connection terminal of the first connector 100, and the optical cable 300 and the optical module body 10 are connected to each other. Guides 220 are formed on both sides of the second connector 200, and the first connector 100 and the second connector 200 are connected to each other by mutual coupling between the guide 220 of the second connector 200 and the guide groove 120 of the first connector 100. The guide 220 is formed in a shape corresponding to the guide groove 120, and is provided in a form to be inserted into the guide groove 120 and slidably provided along the guide groove 120. Since the guide 220 is able to slide freely along the guide groove 120 as described above, the second connector 200 connected to the guide 220 is also able to slide freely in the direction in which the guide 220 moves, making it possible to connect or disconnect the second connector 200 to or from the first connector 100.

[0028] Also, the optical cable 300 is formed with an engagement means 310. The engagement means 310 includes a coupling belt 311 protruding from the outside of the optical cable 300, and a coupling block 312 extending from a side of the coupling belt 311. The coupling belt 311 is a strip-shaped belt having a predetermined thickness and protruding from the outside of the optical cable 300. The coupling belt 311 is formed in a state in which one side is coupled to the optical cable 300 and the other side is not coupled. That is, the other side of the coupling belt 311 can move freely by an external force while ensuring a degree of freedom. The coupling block 312 is a block-shaped member having a predetermined thickness and is formed extending from the center of the coupling belt 311 to both sides of the coupling belt 311. The coupling block 312 is located adjacent to the optical cable 300 or located apart from the optical cable 300 depending on an external force acting on the coupling belt 311.

[0029] Meanwhile, the present invention further includes a coupling / engagement groove 110 formed in the first connector 100 and a release / engagement groove 210 formed in the second connector 200 .

[0030] The coupling / engagement groove 110 is formed on the top surface of the first connector 100 to correspond to the coupling block 312 of the optical cable 300 and to allow the coupling block 312 to be inserted therein.

[0031] The engagement / disengagement groove 210 is formed on the upper surface of the second connector 200 to correspond to the coupling block 312 of the optical cable 300 and to allow the coupling block 312 to be inserted therein.

[0032] When an external force is applied to the coupling belt 311 of the optical cable 300 to push the coupling belt 311, the coupling block 312 is positioned adjacent to the optical cable 300, and the optical cable 300 becomes horizontally movable above the second connector 200. When the external force applied to the coupling belt 311 of the optical cable 300 is stopped, the coupling belt 311 protrudes outward from the optical cable 300, and the coupling block 312 engages with the coupling-engagement groove 110 or the release-engagement groove 210, and the optical cable 300 is fixed.

[0033] The coupling block 312 of the optical cable 300 is inserted into the coupling / engagement groove 110 when the first connector 100 and the second connector 200 are coupled, and is inserted into the release / engagement groove 210 when the first connector 100 and the second connector 200 are released from the coupling.

[0034] In addition, the disconnection unit 400 includes a first rotating protrusion 410 protruding from the first connector 100, a rotating link 430 having one side rotatably connected to the first rotating protrusion 410 and rotating around the first rotating protrusion 410, and a second rotating protrusion 420 protruding from the guide 220 of the second connector 200 and having the other side rotatably connected to the rotating link 430.

[0035] The first rotation protrusion 410 is a circular rod-like protrusion having a predetermined diameter, and protrudes outward from the side surface of the first connector 100 .

[0036] The second rotation protrusion 420 is a circular rod-shaped protrusion having a predetermined diameter, and protrudes outward from a side surface of the guide 220 of the second connector 200. At this time, the second rotation protrusion 420 and the first rotation protrusion 410 are disposed in parallel to each other.

[0037] The rotation link 430 is a bar-shaped structure having a predetermined thickness, and one side thereof is rotatably coupled to the first rotation protrusion 410. At this time, a coupling hole 431 is formed on the other side of the rotation link 430, and the second rotation protrusion 420 is inserted into the coupling hole 431. The coupling hole 431 is formed to have a width larger than that of the second rotation protrusion 420, so that the other side of the rotation link 430 is also rotatably coupled to the second rotation protrusion 420.

[0038] Here, the first rotation protrusion 410, the second rotation protrusion 420, and the rotation link 430 are provided in pairs and are installed on both sides of the first connector 100 and the second connector 200, respectively.

[0039] On the other hand, the present invention further includes a fixed block 440 that is slidably mounted on the first connector 100, and a portion of which is clamped and fixed in the optical module main body 10 by the sliding, and a fixed rod 432 that extends from the end of one side of the rotating link 430, and a portion of which is engaged with the fixed block 440.

[0040] The fixing block 440 is a roughly square box-shaped member having a sandwiching groove formed on one side so that the fixing bar 432 is sandwiched therein, and is provided below the first connector 100 so as to be able to slide in the direction of arrow A in Fig. 5. The fixing block 440 moves toward the optical module main body 10 by the sliding movement, and is engaged with the lower part of the optical module main body 10.

[0041] The fixed rod 432 is a circular rod having a predetermined diameter, and is provided to interconnect the ends on one side of the pair of rotation links 430, and the center portion of the fixed rod 432 is engaged with the sandwiching groove of the fixed block 440.

[0042] The operation of the optical module assembly according to the present invention constructed as described above will now be described in detail with reference to FIGS.

[0043] First, FIG. 1 is a view showing an optical module body 10 according to the present invention before being connected to an optical cable 300. In this state, the optical cable 300 is inserted into the insertion hole of the second connector 200 and coupled.

[0044] 2 is a view showing a state in which the optical cable 300 is inserted into the insertion hole of the second connector 200 to connect the optical module body 10 and the optical cable 300. In this state, the coupling block 312 of the optical cable 300 is positioned so as to be engaged with the coupling / engagement groove 110 of the first connector 100.

[0045] FIG. 3 is a diagram showing one step for separating the optical cable 300 and the optical module body 10. After the coupling block 312 of the optical cable 300 is positioned in the release / engagement groove 210 of the second connector 200, the optical cable 300 is moved a predetermined distance to the left in FIG. 3.

[0046] Next, as shown in Fig. 4, the rotating link 430 is rotated leftward in Fig. 4 to slide the second connector 200 leftward in Fig. 4. When the second connector 200 slides leftward in Fig. 4 as described above, the connection terminal of the optical cable 300 is separated from the internal connection terminal of the first connector 100, and the connection between the optical module body 10 and the optical cable 300 is released.

[0047] FIG. 5 is a drawing showing the state of FIG. 4 from another angle. When the rotating link 430 rotates, the fixed block 440 moves in the direction of arrow A in FIG. 5, and a part of the fixed block 440 is clamped and fixed to the lower part of the optical module body 10.

[0048] The optical module assembly according to the present invention, configured and operated as described above, has the technical effect of enabling the optical module body 10 and the optical cable 300 to be disconnected without separating the optical cable 300, thereby preventing contamination or damage to the connection of the optical cable 300 due to separation of the optical cable 300.
