Description

Technical Field

[0001] This invention belongs to the field of communication base station equipment, and specifically relates to a dust cap that allows for the removal and detachment of optical modules. Background Technology

[0002] The main component for transmitting optical signals on a communication base station is the optical module, which is mostly installed inside the equipment. When an optical module is installed on the equipment and an external socket is connected, the optical module can be removed or removed using the following methods: 1. Directly by hand, such as... Figure 1 As shown; 2. Remove the socket by hand, as shown. Figure 2 As shown; 3. Directly use a customized tool for removal and removal, such as... Figure 3 As shown. These removal and disassembly methods have the following disadvantages: 1. When the optical module is located deep or the socket is too long, it is difficult to remove it manually; 2. The socket is often fixed to the device panel with screws, and the process of disassembling the socket first and then removing it manually is complicated; 3. The installation environment of communication equipment varies greatly, and individual customized tools are prone to being lost or cannot be found when needed, which cannot meet the disassembly requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a dust cap that can remove and detach an optical module. The optical module can be removed and detached by using a removal hook provided on the dust cap. The dust cap is connected to the socket or plug of the connector, so that the optical module can be removed conveniently and quickly without disassembling the socket when it is necessary to remove and detach the optical module.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a dust cap capable of removing and detaching an optical module, comprising a dust cap body, wherein the surface of the dust cap body is provided with a removal hook for removing and detaching the optical module, and the removal hook has a bent hook for pulling out the optical module.

[0005] The surface of the dust cap body is provided with a mounting base, and the removal hook is movably connected to the mounting base.

[0006] In the first configuration, the detachment hook is slidably connected to the mounting base.

[0007] Furthermore, the mounting base is provided with a sliding groove, the bottom surface of which is provided with at least two grooves. The hook handle of the unloading hook is slidably disposed in the sliding groove, and the hook handle is provided with a spring claw. During the sliding process of the unloading hook, the spring claw can be engaged in different grooves.

[0008] Furthermore, the inner walls on both sides of the chute are configured as first inclined surfaces, and the hook handle of the unloading hook is provided with second inclined surfaces on both sides that cooperate with the first inclined surfaces.

[0009] In the second configuration, the detachment hook is rotatably connected to the mounting base.

[0010] Furthermore, the mounting base is provided with a support surface for supporting the hook handle of the detachment hook during the detachment operation.

[0011] The mounting base is provided with a storage groove. The removal hook moves its end hook into and out of the storage groove by rotating. A stop surface is provided in the storage groove. After the hook of the removal hook enters the storage groove, the hook handle of the removal hook is supported on the stop surface.

[0012] Alternatively, the storage slot may be provided with a hook groove to accommodate a hook.

[0013] Furthermore, the unloading hook is provided with an interference fit protrusion that fits into the inner wall of the storage groove.

[0014] Furthermore, the storage slot is provided with retrieval ports on both sides for easy pulling out the retrieval hook.

[0015] Alternatively, after the hook of the detachment hook enters the storage slot, the end of the detachment hook away from the hook protrudes from the storage slot to form a pressing head for pressing the detachment hook.

[0016] The beneficial effects of this invention are: by integrating the removal hook into the dust cap on the socket or plug, the removal hook can be avoided from being lost. When it is necessary to remove or detach the optical module, the optical module can be easily and quickly removed from the device using the removal hook.

[0017] This invention provides a detachable hook that is connected to the dust cap via a sliding pull mechanism. Through the interaction of the spring claw on the hook and the grooves at different positions on the sliding groove, the hook has two states on the dust cap mounting base: working and non-working. In the non-working state, the hook's bent end rests against the mounting base, preventing it from being deformed or damaged by impact. In the working state, the hook extends a certain length, allowing the optical module to be removed using its bent end. Among the designed grooves, the innermost groove corresponds to the non-working state of the hook, while the remaining grooves correspond to the working state, allowing for different extension lengths of the hook to accommodate varying installation depths of the optical module.

[0018] The present invention achieves vertical positioning of the unloading hook and the chute through the cooperation of the first inclined surface and the second inclined surface, and at the same time plays a role in guiding the installation of the unloading hook.

[0019] In this invention, the detachment hook is connected to the dust cap in a rotatable folding manner, so that the detachment hook has two states on the mounting base of the dust cap: working and non-working. In the non-working state, the detachment hook can be retracted into the storage groove of the mounting base to avoid the hook being deformed or damaged by collision. In the working state, the hook of the detachment hook protrudes from the storage groove of the mounting base, and the end of the detachment hook away from the hook rests on the support surface of the mounting base, and the support surface provides support for the detachment hook's detachment action.

[0020] In this invention, the handle of the detachment hook is provided with an interference fit protrusion, which can lock the detachment hook in the storage groove to prevent it from loosening and falling off. In one embodiment, the detachment openings provided on both sides of the storage groove facilitate the removal of the detachment hook from the storage groove. In another embodiment, the end of the detachment hook away from the hook protrudes from the storage groove to form a pressing head, which facilitates the removal of the detachment hook from the storage groove by pressing with the help of the lever principle.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the invention in any way.

[0040] The present invention proposes a structure for a dust cap capable of removing and detaching an optical module, as follows: Figure 4 As shown, it includes a dust cap body 5 and a removal hook 6 located on the outside of the dust cap body 5. The dust cap body 5 is connected to the connector (such as a plug or socket) that requires dust protection via a cable 7 or other connectors to prevent the dust cap from being lost. Figure 4 The connector that needs to be dustproof is plug 4.

[0041] The installation of the unloading hook 6 on the dust cap body 5 can adopt various structural forms, which will be described in detail below with reference to specific embodiments and corresponding drawings.

[0042] Example 1: Refer to Appendix Figure 5-9As shown, in this embodiment, a mounting base 8 is provided at the front end of the dust cap body 5 for mounting the removal hook 6. The mounting base 8 is provided with a sliding groove 801, and the sliding direction allowed by the sliding groove 801 is the axial direction of the dust cap body 5. The hook handle 601 of the removal hook 6 is slidably disposed in the sliding groove 801, and as the removal hook 6 slides, the extension length of the bent hook 603 at the front end of the removal hook 6 can be adjusted.

[0043] To prevent the removal hook 6 from slipping out of the slide groove 801, and to provide support for the removal hook 6 when it picks up the optical module, at least two grooves 803 are spaced apart at intervals along the sliding direction of the removal hook on the bottom of the slide groove 801. Correspondingly, a spring claw 602 that can be locked in the groove 803 is provided on the hook handle 601 of the removal hook 6. When the spring claw of the removal hook 6 is locked in the innermost groove 803 of the slide groove 801, the removal hook is in a non-working state. At this time, the opening of the hook 603 of the removal hook 6 is pressed against the mounting base 8, making it impossible to remove or remove the optical module, and protecting the hook 603 from impact damage. As the removal hook 6 slides outward along the slide groove 801, the spring claw 602 can cooperate with other different grooves 803 except the innermost groove of the slide groove 801, so that the removal hook 6 extends out of the slide groove 801 by different lengths to meet the removal and unloading needs of different usage scenarios. At this time, the removal hook 6 is in a working state. If the optical module is located deep within the optical module, the extension length of the removal hook 6 can be increased so that the hook 603 of the removal hook 6 can reach deep into the optical module for removal.

[0044] like Figure 6 As shown, in this embodiment, the slide 801 is provided with two grooves 803, which correspond to the positions of the unloading hook 6 in two different states. The inner groove 803 corresponds to the non-working state of the unloading hook 6, such as... Figure 9 As shown, after the spring claw 602 of the pick-and-unload hook 6 is engaged in the groove 803, it can prevent the pick-and-unload hook 6 from falling off. At this time, the hook 602 of the pick-and-unload hook 6 retracts, and the end of the hook 602 is pressed against the mounting base 8 to protect the pick-and-unload hook 6 from collisions, etc. The groove 803 located on the outer side corresponds to the working state of the pick-and-unload hook 6, such as... Figure 8 As shown, after the spring claw 602 of the pick-and-unload hook 6 is engaged in the groove 803, the pick-and-unload hook 6 extends a certain length and can hook the optical module to achieve the disassembly of the optical module. Since the spring claw 602 of the pick-and-unload hook 6 is engaged in the groove 803, it can provide certain support for the pick-and-unload hook 6 when hooking the optical module.

[0045] like Figure 7As shown, the spring claw 602 on the unloading hook 6 includes a spring piece disposed on the ventral surface of the unloading hook 6 and a pointed tip disposed on the movable end of the spring piece. The spring piece is suspended in the spring piece movable groove 605 of the unloading hook 6, and a movable gap is left between the spring piece and the top of the spring piece movable groove 605, so that the spring piece can move up and down. The pointed tip on the spring piece is provided with a pressing bevel.

[0046] Continue to refer to Figure 6 To prevent the detachment hook 6 from wobbling within the slide groove 801, the inner walls of both sides of the slide groove 801 are provided with first inclined surfaces 802. The hook handle 601 of the detachment hook 6 has second inclined surfaces 604 on both sides that cooperate with the first inclined surfaces 802. After the detachment hook 6 is installed in the slide groove 801, the first inclined surfaces 802 press against the second inclined surfaces 604 and cooperate with the bottom of the slide groove 801 to clamp the detachment hook 6 between the first inclined surfaces 802 and the bottom of the groove, preventing the detachment hook 6 from loosening and wobbling. Furthermore, the cooperation of the first inclined surfaces 802 and the second inclined surfaces 604 can also guide the detachment hook 6 to be smoothly installed into the slide groove 801.

[0047] Example 2: Refer to Appendix Figure 10-13 As shown, in this embodiment, the end of the pick-and-unload hook 6 away from the bent hook 603 is rotatably connected to the mounting base 8 via a pin. The mounting base 8 is provided with a storage slot 804. The pick-and-unload hook 6 rotates in and out of the storage slot 804. When the pick-and-unload hook 6 is fully inserted into the storage slot 804, the pick-and-unload hook 6 is in a non-working state and cannot pick up the optical module. Figure 10 , 11 As shown, at this time, the hook handle of the detachment hook 6 is supported by the stop surface 808 within the storage groove 804. When the detachment hook 6 rotates away from the storage groove 804, except for the end of the detachment hook 6 that is connected to the storage groove 804 via a pin, the rest of the detachment hook 6 is suspended outside the storage groove 804, as shown. Figure 12 , 13 As shown, the pick-and-unload hook 6 is in working condition at this time and can pick up the optical module.

[0048] Furthermore, such as Figure 12 As shown, interference protrusions 606 are provided on both sides of the detachment hook 6. After the detachment hook 6 enters the storage groove 804, the interference protrusions 606 can be interference-fitted with the two side walls of the storage groove 804 to prevent the detachment hook 6 from loosening.

[0049] Furthermore, such as Figure 10 As shown, a retrieval port 805 is provided on each side of the storage slot 804. The two retrieval ports 805 are arranged opposite each other, so that fingers can be inserted into the retrieval ports 805 to pull the retrieval hook 6 out of the storage slot 804.

[0050] To protect the hook 603 of the removal hook 6, a hook groove 806 is also provided in the storage slot 804. After the removal hook 6 is folded into the storage slot 804, the hook 603 is located in the hook groove 806. Figure 11 As shown.

[0051] The bottom of the storage slot 804 forms the stop surface 808. After the removal hook 6 enters the storage slot 804, the stop surface 808 can support the removal hook 6. The portion of the stop surface 808 extending forward past the pin forms a support surface 807, which can support the removal hook 6 in the working state. The support point is located on the back of the removal hook away from the bent hook 603, thus meeting the support requirements of the removal hook 6 when removing and removing the optical module. Since the stop surface 808 and the support surface 807 are located at different positions on the bottom of the storage slot 804, the rotation angle of the removal hook 6 during its rotation in and out of the storage slot 804 is 180°.

[0052] Example 3: Refer to Appendix Figure 14-17 As shown, in this embodiment, the detachment hook 6 is still rotatably connected to the mounting base 8 by a pin provided at the end away from the hook 603. The mounting base 8 is provided with a storage groove 804, and the detachment hook 6 can move in and out of the storage groove 804 by rotation.

[0053] like Figure 17 As shown, the mounting base 8 is provided with a support surface 807 for supporting the hook handle. After the detachment hook 6 rotates out of the storage slot 804, the side of the hook handle opposite to the hook 603 obtains the support force required by the detachment hook 6 in the process of detaching and removing the optical module by pressing against the support surface 807.

[0054] like Figure 17 As shown, an inclined stop surface 808 is provided inside the storage groove 804, and the stop surface 808 and the support surface 807 form an acute angle. After the removal hook 6 rotates into the storage groove 804, the side of the removal hook 6 opposite to the bent hook 603 abuts against the stop surface 808, as shown. Figure 15 As shown, the unloading hook 6 is tilted at this time, with the hook 603 facing outward from the storage groove 804, and the two sides of the storage groove 804 forming a protection for the hook 603.

[0055] Furthermore, such as Figure 16 As shown, the unloading hook 6 is provided with an interference protrusion 606 that fits with the inner wall of the storage groove 804. After the unloading hook 6 enters the storage groove 804, the interference protrusion 606 can fit with the two side walls of the storage groove 804 to prevent the unloading hook 6 from loosening.

[0056] Furthermore, such as Figure 14 , 15As shown, after the removal hook 6 enters the receiving groove 804, the tail end of the removal hook 6 protrudes from the receiving groove 804, serving as a pressing head 607. By pressing the pressing head 607 of the removal hook 6, the removal hook 6 can be rotated around the pin and exit from the receiving groove 804 until the hook handle of the removal hook 6 rests on the support surface 807. Figure 16 , 17 As shown, the optical module can be removed or removed at this time using the removal hook 6.

[0057] In the above three embodiments, the removal hook is movably mounted on the mounting base. In practice, the removal hook and the mounting base can also be integrated as an integral structure as needed, which can also serve the purpose of removing and detaching the optical module.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of the present invention with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention are within the protection scope of the pending claims.
