Description

Technical Field

[0001] This utility model relates to the field of optical fiber connector technology, and in particular to a connector and an optical fiber connection device. Background Technology

[0002] In fiber optic communication systems, connectors are key components used to enable detachable and reusable insertion and removal between optical fibers and communication equipment. Their connection reliability and ease of installation and removal directly affect the overall system's operation and maintenance efficiency. Connectors can work with devices such as optical modules and data center switches to provide crucial support for low-loss signal transmission in high-density optical networks.

[0003] In existing technologies, connectors are mostly used in high-density cabling environments such as data center cabinets and communication base stations. The front end of the connector has two plugs with independent push handles. Each push handle has a locking protrusion that mates with the adapter. The connector cover is hinged to the outer frame of the connector, and the end of the cover near the push handle engages with the push handle. When it is necessary to change the polarity of the plug, the cover must first be pressed to lower the push handle, causing the locking protrusion to separate from the adapter, thus unlocking the connector from the adapter. Then, the push handle and the cover, as well as the locking parts of the plug and the connector, must be separated to change the polarity of the plug. This process is cumbersome, which greatly reduces the disassembly efficiency of operators and is also structurally complex.

[0004] Therefore, it is necessary to propose a connector and fiber optic connection device to overcome the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a connector and fiber optic connection device that is easy to operate, simplifies the product structure, reduces the number of steps required to change the polarity of the connector, and improves work efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A connector, comprising:

[0008] The outer frame has an internal receiving slot;

[0009] A connector is installed at one end of the outer frame for connecting to the adapter.

[0010] The cover plate is hinged to the wall of the receiving groove in the middle and is located above the plug. The first end of the cover plate is provided with a first locking part. When the plug is plugged into the adapter, the first locking part can lock with the adapter.

[0011] A handle is slidably connected to the receiving groove along a first direction, and the handle is provided with a driving part, which is drivenly connected to the second end of the cover plate;

[0012] When the handle moves away from the outer frame, the drive unit can drive the second end of the cover plate to tilt up, so that the first locking part descends to unlock the adapter.

[0013] Preferably, the connector further includes an elastic element disposed within the receiving groove. One end of the elastic element abuts against the outer frame, and the other end abuts against the first end of the cover plate. The elastic force of the elastic element drives the first end of the cover plate to rise, so that the first locking part can be connected to the adapter.

[0014] Preferably, a limiting post is provided in the receiving groove, and the elastic element is sleeved on the limiting post.

[0015] Preferably, the second end of the cover plate is provided with a guide slope on the side facing the drive unit;

[0016] The drive unit is a boss. When the handle moves away from the outer frame, the boss can push against the guide slope to make the second end of the cover plate rise.

[0017] Preferably, the handle is provided with a hook-shaped part, the outer frame is provided with a first guide groove extending in a first direction, and the hook-shaped part is slidably connected to the first guide groove.

[0018] Preferably, the connector further includes an inner frame, the plug is connected to the inner frame, and the inner frame is detachably connected to the outer frame.

[0019] Preferably, the outer frame is provided with a connecting groove, the inner wall of the connecting groove is provided with a first snap-fit ​​part, and one side of the inner frame is provided with a second snap-fit ​​part. The inner frame is embedded in the connecting groove, and the first snap-fit ​​part snaps with the second snap-fit ​​part.

[0020] Preferably, there are two connectors, which are spaced apart at the ends of the connector.

[0021] There are two second snap-fit ​​parts, which are symmetrically arranged on both sides of the inner frame.

[0022] Preferably, the connector further includes a tail sleeve connected to the end of the handle away from the outer frame.

[0023] An optical fiber connection device includes an optical fiber, an adapter, and a connector as described above. The optical fiber passes through the inside of the connector. The adapter is provided with a plug slot and a second locking part. When the plug is inserted into the plug slot, the first locking part locks with the second locking part.

[0024] The beneficial effects of this utility model are:

[0025] The connector and fiber optic connection device provided by this utility model allows the operator to pull a handle when the connector needs to be unlocked. The handle moves away from the outer frame, and the driving part of the handle is connected to the second end of the cover plate. The driving part can drive the second end of the cover plate to tilt up. Since the middle of the cover plate is hinged to the receiving groove of the outer frame, and the first end of the cover plate is provided with a first locking part for locking the adapter, when the second end of the cover plate tilts up, the cover plate flips around itself, and the first end of the cover plate descends, causing the first locking part to descend and disengage from the adapter, thus completing the connector unlocking. This utility model eliminates the need to press the cover plate when unlocking the connector; simply dragging the handle is sufficient to unlock the connector and adapter, making operation simple. Furthermore, since the first locking part is located on the cover plate, there is no connection between the cover plate and the connector. This simplifies the product structure and eliminates the need to separate the connector from the cover plate when changing the polarity of the connector, reducing operational steps and improving work efficiency.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] In existing technologies, connectors are mostly used in high-density cabling environments such as data center cabinets and communication base stations. The front end of the connector has two plugs with independent push handles. Each push handle has a locking protrusion that mates with the adapter. The connector cover is hinged to the outer frame of the connector, and the end of the cover near the push handle engages with the push handle. When it is necessary to change the polarity of the plug, the cover must first be pressed to lower the push handle, causing the locking protrusion to separate from the adapter, thus unlocking the connector from the adapter. Then, the push handle and the cover, as well as the locking parts of the plug and the connector, must be separated to change the polarity of the plug. This process is cumbersome, which greatly reduces the disassembly efficiency of operators and is also structurally complex.

[0045] Based on the above problems, this embodiment provides a connector, such as... Figure 1 and Figure 2 As shown, the connector provided in this embodiment includes an outer frame 1, a cover plate 2, a handle 3, and a plug 6. The outer frame 1 has an internal receiving groove 11. The plug 6 is installed at one end of the outer frame 1 for insertion into an adapter 8. The middle portion of the cover plate 2 is hinged to the groove wall of the receiving groove 11 and is located above the plug 6. A first locking part 22 is provided at the first end of the cover plate 2. When the plug 6 is inserted into the adapter 8, the first locking part 22 can lock with the adapter 8. The handle 3 is slidably connected to the receiving groove 11 in a first direction, and the handle 3 is provided with a driving part 31, which is driven to the second end of the cover plate 2. When the handle 3 moves away from the outer frame 1, the driving part 31 can drive the second end of the cover plate 2 to tilt upwards, causing the first locking part 22 to descend and unlock from the adapter 8. In this embodiment, the end of the cover plate 2 closest to the adapter 8 is the first end, and the end of the cover plate 2 furthest from the adapter 8 is the second end. The first direction is X, which is the length direction of the connector, and the second direction is Y, which is perpendicular to the second direction.

[0046] The connector and fiber optic connection device provided in this embodiment allow the operator to pull the handle 3 when the connector needs to be unlocked. The handle 3 moves away from the outer frame 1. The driving part 31 of the handle 3 is connected to the second end of the cover plate 2, and the driving part 31 can drive the second end of the cover plate 2 to tilt up. Since the middle part of the cover plate 2 is hinged to the receiving groove 11 of the outer frame 1, and the first end of the cover plate 2 is provided with a first locking part 22 for engaging the adapter 8, when the second end of the cover plate 2 tilts up, the cover plate 2 flips around itself, and the first end of the cover plate 2 descends, causing the first locking part 22 to descend and disengage from the adapter 8, thus completing the connector unlocking. In this embodiment, when unlocking the connector, there is no need to press the cover plate 2; simply dragging the handle 3 is sufficient to unlock the connector and adapter 8, making the operation simple. Furthermore, since the first locking part 22 is located on the cover plate 2, there is no connection between the cover plate 2 and the connector 6. On the one hand, this simplifies the product structure; on the other hand, when it is necessary to change the polarity of the connector 6, there is no need to consider separating the connector 6 from the cover plate 2, reducing operation steps and improving work efficiency.

[0047] Specifically, the receiving groove 11 is located at the top of the outer frame 1, and the cover plate 2 is located at the upper opening of the receiving groove 11. Two hinge grooves 14 are provided at both ends of the receiving groove 11, and two hinge posts 23 are provided on both sides of the middle part of the cover plate 2. The hinge posts 23 are hinged to the hinge grooves 14 to realize the cover plate 2 rotating around its own axis.

[0048] In some embodiments, the connector further includes an elastic element 4 disposed within the receiving groove 11. One end of the elastic element 4 abuts against the outer frame 1, and the other end abuts against the first end of the cover plate 2. The elastic force of the elastic element 4 drives the first end of the cover plate 2 to rise, so that the first locking part 22 can be connected to the adapter 8. The elastic element 4 can reset the cover plate 2 by its own elastic force, preparing for the next insertion of the connector.

[0049] Preferably, a limiting post 111 is provided in the receiving groove 11, and the elastic member 4 is sleeved on the limiting post 111, which can form a radial limit on the elastic member 4, restricting the elastic member 4 to deform only along the axial direction of the limiting post 111, and at the same time improving the structural reliability of the elastic member 4.

[0050] Preferably, the bottom of the cover plate 2 is provided with an abutment groove 24, and the top end of the elastic member 4 abuts against the abutment groove 24 to limit the elastic member 4 from shifting radially.

[0051] Specifically, in this embodiment, the elastic element 4 is a spring, the limiting post 111 is disposed on the bottom wall of the receiving groove 11, the spring is sleeved on the outer periphery of the limiting post 111, its bottom end abuts against the bottom wall of the receiving groove 11, and its top end abuts against the abutting groove 24 on the inner wall of the cover plate 2, thereby improving the stability of the spring.

[0052] Preferably, such as Figure 3As shown, a guide slope 211 is provided on the side of the second end of the cover plate 2 facing the drive part 31; the drive part 31 is a boss. When the pull handle 3 moves away from the outer frame 1, the boss can push against the guide slope 211 to make the second end of the cover plate 2 rise. It is a key structure for unlocking and fixing the connector.

[0053] In this embodiment, two guide protrusions 21 are provided at intervals along the second direction at the bottom of the second end of the cover plate 2, and guide ramps 211 are provided on the side wall of the two guide protrusions 21 near the drive part 31.

[0054] In this embodiment, there are two bosses, which are spaced apart along the second direction on the top of the handle 3 near the second end of the cover plate 2 and correspond one-to-one with the two guide slopes 211.

[0055] Specifically, the bottom of the cover plate 2 is provided with two first clearance grooves 25, each corresponding to one of the two bosses. The handle 3 is provided with two second clearance grooves 34, each corresponding to one of the two guide ramps 211. When the first locking part 22 of the cover plate 2 is locked with the adapter 8, the two guide bosses 21 can be inserted into the two second clearance grooves 34, and the two bosses can be inserted into the two first clearance grooves 25. This provides clearance space for the flipping of the cover plate 2, limits the flipping angle of the cover plate 2, improves the structural stability of the connector, reduces space occupation, and optimizes the structural layout.

[0056] In some embodiments, one side of the boss pushing against the guide slope 211 is curved, which can improve the smoothness of the boss pushing against the guide slope 211, improve the disassembly efficiency of the connector, reduce wear, and increase the service life of the connector.

[0057] Preferably, the drive part 31 can also be a cylindrical pin, which is vertically fixed to the top of the handle 3. The bottom of the second end of the cover plate 2 is provided with an arc-shaped groove facing the drive part 31. The diameter of the cylindrical pin matches the width of the arc-shaped groove, and the top of the cylindrical pin abuts against the groove wall of the arc-shaped groove. When the handle 3 moves away from the outer frame 1, the cylindrical pin can slide in the arc-shaped groove, pushing against the groove wall, causing the second end of the cover plate 2 to rise and the first end to fall, causing the first locking part 22 to fall to disengage from the adapter 8, thereby unlocking the connector.

[0058] like Figure 4 and Figure 5 As shown, in some embodiments, the handle 3 is provided with a hook-shaped portion 32, and the outer frame 1 is provided with a first guide groove 12 extending along a first direction. The hook-shaped portion 32 is slidably connected to the first guide groove 12. On the one hand, the first guide groove 12 can limit the sliding distance of the handle 3 in the first direction and prevent the handle 3 from being pulled off; on the other hand, the first guide groove 12 can provide guidance for the handle 3 to move along the first direction and improve the moving accuracy of the handle 3.

[0059] In some embodiments, there are two hook-shaped portions 32, which are spaced apart at the bottom of the handle 3. There are also two first guide grooves 12, which are located at the bottom of the outer frame 1 and correspond one-to-one with the two hook-shaped portions 32.

[0060] Preferably, the handle 3 can move along the first direction to the unlocking position and the locking position. When the handle 3 moves away from the outer frame 1 to the unlocking position, under the driving action of the drive unit 31, the first end of the cover plate 2 moves down and compresses the spring. The first locking part 22 of the cover plate 2 moves down to disengage from the adapter 8, so that the connector is unlocked from the adapter 8. When the handle 3 moves towards the outer frame 1 to the locking position, the drive unit 31 separates from the guide slope 211. Under the action of the spring force, the top of the spring pushes the first end of the cover plate 2 to lift up, so that the first locking part 22 of the cover plate 2 lifts up and engages with the adapter 8, so that the connector is fixedly connected to the adapter 8.

[0061] In some embodiments, the connector further includes an inner frame 5, a plug 6 connected to the inner frame 5, and the inner frame 5 is detachably connected to the outer frame 1 to achieve a fixed connection between the plug 6, the inner frame 5, and the outer frame 1.

[0062] Specifically, the connector 6 includes a front frame 61 and a plug 62, with the plug 62 located at one end of the front frame 61 near the adapter 8.

[0063] In some embodiments, the connector 6 further includes a stop ring 63. The connector 6 and the inner frame 5 are connected via the stop ring 63. The connection between the connector 6 and one end of the stop ring 63 is detachable, and the connection between the inner frame 5 and the other end of the stop ring 63 is also detachable, thus achieving the connection between the connector 6 and the inner frame 5 via the stop ring 63. In this embodiment, the detachable connection between the two ends of the stop ring 63 is a snap-fit ​​connection between a buckle and a slot.

[0064] Preferably, the outer frame 1 is provided with a connecting groove 13, the inner wall of the connecting groove 13 is provided with a first snap-fit ​​part 131, and one side of the inner frame 5 is provided with a second snap-fit ​​part 51. The inner frame 5 is embedded in the connecting groove 13, and the first snap-fit ​​part 131 and the second snap-fit ​​part 51 are snapped together to fix the inner frame 5 and the outer frame 1, so as to prevent the inner frame 5 from moving inside the outer frame 1.

[0065] Specifically, the connecting groove 13 is located below the receiving groove 11, the first snap-fit ​​part 131 is located on the bottom wall of the connecting groove 13, and the second snap-fit ​​part 51 is located on the bottom of the inner frame 5 near the handle 3. When the inner frame 5 is inserted into the connecting groove 13, the second snap-fit ​​part 51 snaps into the first snap-fit ​​part 131, which can fix the inner frame 5 inside the outer frame 1.

[0066] In this embodiment, the first snap-fit ​​part 131 is an elastic boss, and the second snap-fit ​​part 51 is a groove that matches the shape of the elastic boss. The elastic boss can snap into the groove. When the connector is in the locking position, the elastic boss snaps into the groove. When the connector is in the unlocking position, the elastic boss can disengage from the groove, which facilitates the disassembly and installation of the inner frame 5 and the outer frame 1.

[0067] In some embodiments, there are two connectors 6, which are spaced apart at the ends of the connector. There are also two second snap-fit ​​portions 51, which are symmetrically arranged on both sides of the inner frame 5.

[0068] Specifically, two connectors 6 are spaced apart at the end of the inner frame 5 away from the handle 3. Two second locking parts 51 are symmetrically arranged at the top and bottom of the end of the inner frame 5 away from the adapter 8. When the operator needs to change the polarity of the connector, he pulls the connector 6 in the first direction towards the end away from the handle 3, so that the first locking part 131 is disengaged from the second locking part 51 on one side, the inner frame 5 is taken out, and after the inner frame 5 is flipped 180 degrees, it is inserted into the connecting slot 13 of the outer frame 1. Since the two second locking parts 51 are symmetrically arranged on both sides of the inner frame 5, the flipped inner frame 5 can also be fixed to the outer frame 1 again by the second locking part 51 on the other side and the first locking part 131, which makes it convenient for the operator to change the polarity of the connector.

[0069] In the existing technology, the operator needs to pull the lever located at the top of the tail sleeve to unlock the connector. Since the lever and the tail sleeve are designed separately, sufficient operating space must be reserved for the lever when the connector is plugged in and installed, which directly increases the overall volume occupied by the connector and restricts the improvement of the wiring density inside the cabinet or base station.

[0070] To address the aforementioned issues, the connector provided in this embodiment further includes a tail sleeve 7, which is connected to the end of the handle 3 furthest from the outer frame 1. The operator can pull the tail sleeve 7, which in turn moves the handle 3, causing the cover plate 2 to flip, thereby unlocking the connector from the adapter 8. This embodiment combines the handle 3 and the tail sleeve 7, simplifying the connector structure, reducing space occupation, improving space utilization, and preventing interference with surrounding connectors when the handle 3 is pulled, thus meeting the needs of rapid maintenance operations in high-density wiring environments.

[0071] Specifically, the outer periphery of the end of the tail sleeve 7 connected to the handle 3 is provided with a snap-fit ​​protrusion 71, and the inner end of the handle 3 near the tail sleeve 7 is provided with a snap-fit ​​groove 33. The bottom of the snap-fit ​​groove 33 is provided with a through hole 35, the tail sleeve 7 passes through the through hole 35, and the snap-fit ​​protrusion 71 can be embedded in the snap-fit ​​groove 33. After the inner frame 5 is assembled, it abuts against the end of the snap-fit ​​protrusion 71 away from the snap-fit ​​groove 33. The bottom of the inner frame 5 and the groove of the snap-fit ​​groove 33 abut against the two ends of the snap-fit ​​protrusion 71 of the tail sleeve 7, so that the tail sleeve 7 and the handle 3 are fixedly connected, and the two form a stable integral structure.

[0072] This embodiment provides an optical fiber connection device, which includes an optical fiber, an adapter 8, and the aforementioned connector. The optical fiber passes through the connector. The adapter 8 is provided with a insertion slot 81 and a second locking part 82. When the connector 6 is inserted into the insertion slot 81, the first locking part 22 and the second locking part 82 lock together to achieve a fixed connection of the optical fiber connection device. Since the cover plate 2 and the connector 6 in the aforementioned connector do not need to be snapped together, the structure of the optical fiber connection device is simplified. Moreover, when replacing the plug, there is no need to consider the disassembly between the cover plate 2 and the connector 6, reducing the number of operation steps. Combining the handle 3 and the tail sleeve 7 simplifies the connector structure, reduces the space occupied by the connector, improves space utilization, avoids interference with surrounding connectors when pulling the handle 3, and adapts to the needs of rapid maintenance operations in high-density cabling environments.

[0073] Preferably, there are two insertion slots 81, which are spaced apart and positioned at the end of the adapter 8 near the connector 6. The first locking part 22 is a snap-fit, and the second locking part 82 is a slot. The slot is disposed through the upper wall of the insertion slot 81 near the connector 6. The snap-fit ​​and the slot are fixed together by snap-fit ​​to secure the connector and the adapter 8. There are two first locking parts 22 and two second locking parts 82. The two first locking parts 22 are spaced apart at the first end of the cover plate 2 and correspond one-to-one with the two second locking parts 82. Of course, the first locking parts 22 and the second locking parts 82 can also adopt other locking structures, such as magnetic locking. Magnetic elements such as permanent magnets are built into the first locking parts 22 and the second locking parts 82 to achieve locking using magnetic force, which is convenient for disassembly.

[0074] When reversing polarity, the operator only needs to pull the tail sleeve 7. The tail sleeve 7 moves the handle 3, and the handle 3 drives the cover plate 2 to flip, so that the first locking part 22 of the cover plate 2 is disengaged from the second locking part 82 of the insertion slot 81, thereby unlocking the connector and adapter 8. Then, the inner frame 5 is taken out, flipped 180 degrees and inserted into the outer frame 1. Next, the connector is inserted into the insertion slot 81. Since there is a spring at the bottom of the cover plate 2, its elasticity can drive the cover plate 2 to reset. Under the action of the spring, the first locking part 22 and the second locking part 82 are engaged, thus completing the fixation of the connector and adapter 8.

[0075] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
