Description

[Technical Field]

[0001] The present invention relates to a fiber optic adapter, and more particularly to a fiber optic adapter with a movable door. [Background technology]

[0002] In recent years, optical fibers have been widely used as a signal transmission medium due to their advantages of wide bandwidth and low loss. To achieve longer-distance signal transmission, high-power laser diodes have been developed, significantly increasing the energy coupled into optical fibers. However, when a high-intensity infrared beam is emitted from one end of an optical fiber, the human eye cannot distinguish the presence or absence of the beam. Therefore, workers who accidentally expose their eyes to the beam often suffer permanent visual impairment.

[0003] Furthermore, optical fiber communication transmission is sensitive to dust. If proper protection measures are not taken when the adapter is empty or when it is being plugged into or unplugged from the corresponding optical fiber connector, dust will enter the adapter, increasing loss and affecting optical signal transmission. However, currently, adapters suitable for MPO and MTP optical fiber connectors generally do not have corresponding dustproof structures or simply cover unused connection ports with additional dust caps. In the latter case, users still need to remove the dust caps before plugging or unplugging the connector, and the removed dust caps are also stored separately, which can easily cause management concerns. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention provides an optical fiber adapter with a movable door, which has a movable door structure that can be opened and closed depending on the insertion and removal of a connector, thereby improving the convenience of using the optical fiber adapter and improving its manageability. [Means for solving the problem]

The housing has two connection ports facing each other, and the housing has at least a pair of first plug-in slots adjacent to at least one of the two connection ports. The movable door is assembled to at least one of the two connection ports. The movable door includes a door frame and at least one door panel, the door panel is pivotally connected to the door frame, and the door frame has a pair of first latches that are slidably inserted into the first plug-in slots and locked to the housing.

[0007] In one embodiment of the present invention, the first latch slides in the first plug-in slot along an axial direction, and the axial direction is perpendicular to the plane on which the connection port is located.

[0008] In one embodiment of the present invention, the first latch slides in the first plug-in slot along an axial direction, and the first plug-in slot and the first latch have a stepped profile along the axial direction so as to fit snugly together.

[0009] In one embodiment of the present invention, the housing further includes a plurality of second latches extending from the inner wall of the housing adjacent to the first plug-in slots, and the movable door further includes a plurality of second plug-in slots adjacent to the first latches, and the second latches are inserted into the second plug-in slots respectively.

[0013] In one embodiment of the present invention, the first latch and the third latch belong to the same elastic arm structure.

[0014] In one embodiment of the present invention, the door frame has two side wings facing each other and extending toward the housing, and the first latch is a local structure of the side wing, and the first latch is connected between the side wing and the third latch.

[0015] In one embodiment of the present invention, the door frame further includes a plurality of second fixing parts, and the housing further includes a plurality of first fixing parts, and when the first fixing parts and the second fixing parts are engaged with each other, the door frame is fixed to the housing. One of the first fixing parts and the second fixing parts includes a fixing hole, and the other of the first fixing part and the second fixing part includes a fixing block, and when engaged with each other, the fixing block fits into the fixing hole and interferes with each other's structure.

[0022] FIG. 1 is a schematic diagram of an optical fiber adapter according to an embodiment of the present invention. FIG. 2 is a schematic diagram of docking an optical fiber connector via the optical fiber adapter. FIG. 3 is an exploded schematic diagram of the optical fiber adapter. Referring simultaneously to FIGS. 1 to 3, in this embodiment, an optical fiber adapter 100 provides a space for docking of optical fiber connectors 200 and 300. The optical fiber adapter 100 includes a housing 110 having two opposing connection ports (here, a first connection port 111 and a second connection port 112 are shown as examples). The optical fiber connectors 200 and 300 are inserted into the housing 110 via the first connection port 111 and the second connection port 112, respectively, and docking is completed in the internal space of the housing 110.

[0023] FIG. 4 shows the components of the optical fiber adapter from another perspective. Here, Cartesian coordinates XYZ are provided to facilitate the description of the components. Referring to FIGS. 3 and 4 simultaneously, in order to meet the aforementioned needs for use, such as dust resistance and ease of operation, the optical fiber adapter 100 of this embodiment further includes a movable door 120 assembled to the first connection port 111 of the housing 110. The housing 110 further includes first plug-in slots 113 located on opposite side walls of the housing 110. The movable door 120 includes a door frame 121 and at least one door panel 122. The door panel 122 is pivotally connected to the door frame 121. More importantly, the door frame 121 includes a pair of first latches 124 that are slidably inserted into the first plug-in slots 113 and engaged with the housing 110, allowing the movable door 120 to be smoothly assembled to the first connection port 111 of the housing 110.

[0024] FIG. 5 is an exploded schematic view of a movable door. Referring simultaneously to FIGS. 3 to 5, the movable door 120 of this embodiment further includes a pivot 128 and a torsion spring 123. The at least one door panel 122 essentially includes a pair of door panels 122 that can be opened in both directions. The door frame 121 further includes a pair of side wings 121a each extending toward the housing 110 (in the positive direction of the Z-axis). The door panels 122 are connected to the side wings 121a of the door frame 121 via pivots 128. The torsion spring 123 is fitted to the pivot 128 and abuts between the door panel 122 and the door frame 121 (the main body of the door frame 121, i.e., the main structure having the opening). The torsion spring 123 constantly drives the door panel 122 toward the door frame 121 (i.e., toward the main body of the door frame 121 to close the opening). During the process of inserting the optical fiber connector 200 into the optical fiber adapter 100, the optical fiber connector 200 pushes open the door panel 122, deforming the torsion spring 123 (opening the opening). Conversely, after the optical fiber connector 200 is pulled out of the optical fiber adapter 100, the elastic force accumulated in the torsion spring 123 due to the deformation restores the door panel 122 to its original position, and the door panel 122 returns to the state where it is closed on the door frame 121, as shown in FIG. 2.

[0025] As shown in FIG. 1 , the optical fiber adapter 100 of this embodiment further includes a dust cap 130 that is removably inserted into the housing 110 and closes the second connection port 112. Here, the dust cap 130 is used solely as a reference for the movable door 120. That is, for the first connection port 111, which requires frequent insertion and removal, installing the movable door 120 as described above can achieve both dust prevention and convenience. On the other hand, for the second connection port 112, which does not require frequent insertion and removal and is installed, for example, inside a device, the dust cap 130 can be used as a protective measure after manufacturing is complete and before use. In another embodiment (not shown), the second connection port 112 can also be provided with a movable door 120, similar to the first connection port 111. That is, the movable door 120 can effectively overcome the inconvenience of the dust cap 130.

[0026] 3 to 5, in this embodiment, the housing 110 further includes a plurality of first fixing portions 115 to improve the structural strength of the movable door 120 and the housing 110 after assembly. The movable door 120 also includes a plurality of second fixing portions 126 on the top and bottom of the door frame 121. When the first fixing portions 115 and the second fixing portions 126 are engaged with each other, the door frame 121 is fixed to the housing 110. One of the first fixing portions 115 and the second fixing portions 126 includes a fixing hole, and the other of the first fixing portion 115 and the second fixing portion 126 includes a fixing block. When engaged with each other, the fixing block fits into the fixing hole, interfering with each other's structure. More specifically, the first fixing portion 115 includes a first guide slope 115a and a fixing hole 115b, with the first guide slope 115a facing outward and the fixing hole 115b facing inward. The second fixed portion 126 has a second guide slope 126a and a fixed block 126b, with the second guide slope 126a facing outward and the fixed block 126b facing inward. Therefore, during the process of assembling the movable door 120 to the housing 110, the first guide slope 115a and the second guide slope 126a first slide against each other to dock, and after they separate, the fixed block 126b sequentially fits into the fixing hole 115b, thereby achieving the aforementioned structural interference. That is, it can be considered that the first fixed portion 115 and the second fixed portion 126 are on each other's assembly path, with the first guide slope 115a and the second guide slope 126a located at the initial positions of their respective assembly strokes, and the fixing hole 115b and the fixed block 126b located at the final positions of their respective assembly strokes.

[0027] 3 to 5, in terms of the physical structure of the housing 110, a pair of first plug-in slots 113 are connected to the first connection port 111 and are located on opposite sides of the first connection port 111. That is, the first plug-in slots 113 can be considered to be located on opposite sides of the first connection port 111 along the Y axis. Furthermore, the first latch 124 slides within the first plug-in slots 113 along the Z axis, and the first interface 111 can be considered to be located on the XY plane along the Z axis direction, with the first connection port 111 located on a plane parallel to the XY plane, and the first plug-in slots 113 and the first latches 124 each have a stepped profile so as to fit snugly together. Whether the first latch 124 engages with the positioning notch 113a located at the closed end of the first plug-in slot 113, or the first fixing portion 115 and the second fixing portion 126 engage with each other, either is used to prevent the movable door 120 from falling off the housing 110.

[0028] Meanwhile, the housing 110 further includes second latches 114 adjacent to the first plug-in slots 113 and extending from the inner wall of the housing 110. Correspondingly, the movable door 120 further includes second plug-in slots 127 adjacent to the first latches 124. When the first latches 124 are inserted into the first plug-in slots 113, the second latches 114 are also inserted into the corresponding second plug-in slots 127, so that the first latches 124, the first plug-in slots 113, the second latches 114, and the second plug-in slots 127 form an interlocking structure.

[0029] 6 and 7 are local cross-sectional views of the movable door from different perspectives. FIG. 8 is a local cross-sectional view of the movable door and the housing after assembly. First, referring to FIGS. 5 to 7, the local structure of the door frame 121 is compared with the overall structure to clearly understand the characteristics of the above-mentioned interlocking structure. In this embodiment, with respect to the door frame 121, the first latch 124 is a local structure of the side wing 121a, and the two second plug-in slots 127 are located on opposite sides of the first latch 124 along the X axis. Therefore, referring to FIG. 8, after the door frame 121 is assembled to the housing 110, inserting one of the second latches 114 into the second plug-in slot 127 is equivalent to supporting one side of the first latch 124. Therefore, when the structural features of the "half" door frame 121 shown in Figure 6 or Figure 7 are restored to the structural features of the "complete" door frame 121 shown in Figure 5, it is equivalent to a local portion of the first latch 124 being sandwiched between two second latches 114 along the X axis.

[0030] The movable door 120 further includes a pair of third latches 125 extending from the door frame 121. The third latches 125 and the first latches 124 are located on opposite sides of the door frame 121 along the Z axis and extend back to back. Taking FIG. 4 as an example, the first latch 124 extends in the positive direction of the Z axis, and the third latch 125 extends in the negative direction of the Z axis. When the optical fiber connector 200 is inserted into the optical fiber adapter 100, the third latches 125 engage with the optical fiber connector 200, thereby fixing the optical fiber connector 200 within the housing 110. As can be seen from FIGS. 6 to 8, the first latches 124 and the third latches 125 belong to the same elastic arm structure 125a. That is, based on the side wing 121a of the door frame 121, the first latch 124 extends to one side, and the third latch 125 extends to the other side via the first latch 124, and the first latch 124 is connected between the side wing 121a and the third latch 125. At the same time, the upper and lower ends of the elastic arm structure 125a along the X axis are second plug-in slots 127, respectively.

[0031] 9 and 10 are cross-sectional views of the optical fiber adapter at different degrees. FIG. 11 is a partially enlarged view of the housing. Referring simultaneously to FIGS. 9 and 11, in comparison with the resilient arm structure 125a, the second latch 114 of this embodiment has an L-shaped cantilever structure and includes a first arm portion 114a and a second arm portion 114b. The first arm portion 114a extends along the Y-axis toward the inner space of the housing 110 and then extends toward the movable door 120 (in the negative direction of the Z-axis) to form the second arm portion 114b. Therefore, the structural features of the different cuts in FIGS. 9 and 10 can be used to understand the relevant structural relationships. As shown in FIG. 9, the cut position on the Z-axis is close to the door panel 122, so the upper and lower edges of the resilient arm structure 125a abut against the second arm portion 114b, respectively, and a gap exists between the resilient arm structure 125a and the side wing 121a. 10, the cutting position on the Z axis is away from the door panel 122 and close to the internal space of the housing 110, so it can be seen that the first latch 124 extending from the side wing 121a is essentially clamped by the first arm portion 114a. Based on the above, the door frame 121 of the movable door 120 can be stably assembled in the housing 110 through the interfitting relationship between the first latch 124, the first plug-in slot 113, the second latch 114 and the second plug-in slot 127.

[0032] 2, 4, and 11, in this embodiment, the optical fiber connector 200 has a joint 220 and a rib 210 above the joint 220. The optical fiber connector 300 has a joint 320 and a rib 310 below the joint 320. Correspondingly, the housing 110 of the optical fiber adapter 100 further has limiting grooves 116a and 116b. FIG. 12 is a cross-sectional view of the optical fiber connector of FIG. 2 after it has been assembled to the optical fiber adapter. Referring to FIG. 12, the extension direction of the limiting grooves 116a and 116b in this embodiment is parallel to the central axis CX of the optical fiber adapter 100 (corresponding to being parallel to the Z-axis). Therefore, the limiting groove 116a fits into the rib 210 and restricts its position, and the limiting groove 116b fits into the rib 310 and restricts its position. Furthermore, since the ribs 210 and 310 in this embodiment are arranged above and below the central axis CX, the limiting grooves 116a and 116b are also arranged above and below the central axis CX, as described above. 12, the optical fiber connectors 200 and 300 of this embodiment have anti-symmetrical profiles in side view at their joints 220 and 320. That is, with respect to the central axis CX as the reference, the vertical surface 221 and the inclined surface 222 of the joint 220 are arranged above and below each other, and the vertical surface 321 and the inclined surface 322 of the joint 320 are arranged above and below each other, and the central axis CX substantially passes through the inclined surfaces 221 and 322.

[0033] FIG. 13 is a cross-sectional view of an optical fiber adapter and an optical fiber connector according to another embodiment of the present invention after docking. Referring to FIG. 13, optical fiber connectors 500, 600 are respectively assembled in the housing 410 of the optical fiber adapter. The difference from the previous embodiment is that the ribs 510, 610 of the optical fiber connectors 500, 600 are located on the same side of the central axis CX (both located below the central axis CX), and the limiting groove 416 of the housing 410 is located below the central axis CX, forming an integral structure. In other words, the limiting groove 416 is adapted to simultaneously insert and position the ribs 510, 610. Furthermore, the optical fiber connectors 500, 600 of this embodiment have a side view in which the outline of the joint is two flat surfaces that contact each other. Here, regardless of whether the optical fiber connectors of this embodiment or the previous embodiments 200, 300, 500, 600 are used, the cooperation of the ribs 210, 310, 510, 610 and the limiting grooves 116a, 116b, 416 allows the user to easily perform the relevant insertion and removal operations.

[0034] In summary, in the above embodiment of the present invention, at least one connection port of the optical fiber adapter housing has a first plug-in slot. When the movable door is assembled to the connection port, the first latch of the movable door is slidably inserted into the first plug-in slot and engages with the housing. Simultaneously, the second latch of the housing is inserted into the second plug-in slot of the door frame during the insertion process. The interlocking relationship between the first latch, the first plug-in slot, the second latch, and the second plug-in slot completes the connection between the side walls of the door frame and the side walls of the housing. Furthermore, the main body of the door frame and the corresponding top and bottom plates of the housing can also be connected via first and second fastening parts, thereby improving the connection strength between the movable door and the housing.

[0035] In this way, by disposing a movable door on the connection port of the optical fiber adapter, the movable door closes the connection port when the connection port is not in use, and when the connection port is in use, the optical fiber connector can push open the movable door and enter the internal space of the optical fiber adapter. Therefore, the movable door provides a simple and convenient connection port opening and closing structure, and the connection port can meet the needs both when in use and when not in use. In short, the movable door can be disposed on the connection port of the optical fiber adapter according to the use needs, and the needs of shielding, dust prevention, and ease of use can be simultaneously met. [Industrial Applicability]
