Description

Technical Field

[0001] This utility model relates to the field of optical module technology, specifically to a pull-ring independent disassembly and assembly structure and an optical module. Background Technology

[0002] In traditional optical modules, the pull ring is first assembled onto the base or top cover of the structural component, and then fixed to the top cover or base with screws or rivets. At this time, the pull ring is limited to the sliding range of the base and top cover. Once the pull ring has a problem and needs to be replaced, the base and top cover can only be disassembled and reassembled. After disassembling and replacing the pull ring, the optical module also needs to be retested, which wastes a lot of manpower and resources. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pull-ring independent disassembly and assembly structure and an optical module to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A pull ring independent detachable structure includes: a pull ring and a structural component. The structural component has sliding grooves on two sides along its length, penetrating the end face of its open end. The pull ring is engaged with the base of the structural component, and its two unlocking arms are respectively movable within the two sliding grooves. The bottom and / or top of the sliding grooves have travel grooves distributed along their length. The unlocking arms are provided with limiting parts that enter the travel grooves. The side of the structural component has a corresponding position with a clearance opening communicating with the travel groove. The unlocking arm has a U-shaped hole with an opening facing the unlocking protrusion. A spring piece is formed on the unlocking arm at the U-shaped hole. A limiting groove is formed in the area of ​​the sliding groove corresponding to the spring piece. The movable end of the spring piece is located in the limiting groove and can abut against the side wall of the limiting groove during movement to limit the limiting part and the clearance opening.

[0006] The beneficial effects of this utility model are:

[0007] When the pull ring is pulled outwards, the unlocking arm of the pull ring can move within the groove, allowing it to maintain its original unlocking function. Because the movable end of the spring clip can abut against the side wall of the limiting groove during the movement of the unlocking arm within the groove, and the limiting part and the clearance opening are not aligned when the movable end of the spring clip abuts against the side wall of the limiting groove, the unlocking arm will not disengage from the groove on the structural component. This prevents the pull ring from being pulled out. When removing the pull ring from the structural component, only the movable end of the spring clip needs to be pried open from the outside. Without pressing against the side wall of the limiting groove or disengaging from the limiting groove, continue pulling the pull ring outwards until the limiting part on the unlocking arm aligns with the clearance opening. The pull ring can then be removed from the structural component without disassembling the structural component. Similarly, during assembly, position the two unlocking arms of the pull ring on both sides of the structural component and align the limiting part with the clearance opening. Then push the pull ring towards the gold finger end of the structural component to allow the spring piece to enter the limiting groove. This process also does not require disassembling the structural component, ensuring that the two are independent and do not affect each other.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a pry hole is opened in the slide groove, and the pry hole penetrates the side wall of the limiting groove so as to abut against the spring piece.

[0010] The further beneficial effect of adopting the above is that the pry opening makes it easy to pry the movable end of the spring piece with a tool, so that the movable end of the spring piece does not abut against the side wall of the limiting groove or disengage from the limiting groove.

[0011] Furthermore, on the end face of the light port of the structural component, a slot distributed along its length is opened at each corresponding slide groove. The slot is located on the side of the unlocking arm away from the base, and the unlocking arm is provided with a stop part that enters the slot at the corresponding slot.

[0012] The further beneficial effect of adopting the above is that by allowing the stop part to enter the slot, the pull ring can be prevented from opening outward at the open end of the structural component.

[0013] Furthermore, grooves distributed along the length direction are opened on the base facing the base of the pull ring. The base of the pull ring is provided with a stop part that enters the groove. A return spring is arranged in the groove, with one end of the return spring abutting against the stop part and the other end of the return spring abutting against the groove wall away from the limiting part.

[0014] The further beneficial effect of adopting the above is that when the pull ring and the structural component are assembled, the return spring will be compressed when the pull ring is pulled outward. If the pull ring is released, the return spring can allow the pull ring to return to its original position.

[0015] Based on the above technical solution, this utility model also provides an optical module, including the above-mentioned pull ring independent detachable structure.

[0016] The further beneficial effects of adopting the above are as follows: the pull ring can be disassembled and assembled with the structural components without opening them; the optical module can be tested without the pull ring; after the test is completed, the pull ring is finally installed to complete the finished product assembly; if the pull ring is missing during the testing process and the test module fails, only the top cover needs to be removed; at the same time, the top cover, base and engine can be assembled in advance; different pull rings can be installed according to different customers; if a customer returns the product and needs to replace the pull ring for another customer, the pull ring can also be replaced without opening the structural components, which is convenient, simple and efficient.

[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] Example 1

[0027] like Figures 1-6As shown, a pull ring independent detachable structure includes: a pull ring 1 and a structural component 2. The structural component 2 has grooves 210 on two sides along its length, penetrating the end face of its open end. The pull ring 1 is engaged with the base 220 in the structural component 2, and the two unlocking arms 110 of the pull ring 1 are respectively movably located within the two grooves 210. The bottom and / or top of the grooves 210 have stroke grooves 211 distributed along their length. Normally, the stroke grooves 211 are located near the unlocking protrusions of the unlocking arms 110. In this embodiment, the travel groove 211 can be formed at the bottom of the slide groove 210, at the top of the slide groove 210, or at both the bottom and top of the slide groove 210. The accompanying drawings show one travel groove 211 at both the bottom and top of the slide groove 210. In practical applications, any one of these three methods can be used. The unlocking arm 110 is provided with a limiting part 111 that enters the travel groove 211. If there is only one travel groove 211 in each slide groove 210, then each unlocking arm... Each unlocking arm 110 has only one limiting part 111. If each slide groove 210 contains two travel grooves 211, then each unlocking arm 110 has two limiting parts 111. A clearance opening 230 communicating with the travel groove 211 is opened at a corresponding position on the side of the structural component 2. When the pull ring 1 is assembled with the structural component 2, the limiting part 111 on the unlocking arm 110 can enter the travel groove 211 through the clearance opening 230. A U-shaped hole 112 with an opening facing the unlocking protrusion is opened on the unlocking arm 110, and a spring is formed at the U-shaped hole 112 on the unlocking arm 110. The spring piece 113 is provided, and a limiting groove 240 is provided in the area corresponding to the spring piece 113 in the sliding groove 210. The movable end of the spring piece 113 is located in the limiting groove 240. During the movement of the unlocking arm 110 in the sliding groove 210, the movable end of the spring piece 113 can abut against the side wall of the limiting groove 240 to limit the alignment of the limiting part 111 with the avoidance opening 230. That is, the limiting groove 240 can limit the distance that the pull ring 1 can be pulled. This distance meets the unlocking requirements of the pull ring 1, but also ensures that the limiting part 111 is not aligned with the avoidance opening 230. If they are aligned, the pull ring 1 is easy to fall off the structural component 2.

[0028] When the pull ring 1 is pulled outward, the unlocking arm 110 of the pull ring 1 can move within the slide groove 210, allowing the unlocking arm 110 of the pull ring 1 to maintain its original unlocking function. Since the movable end of the spring piece 113 can abut against the side wall of the limiting groove 240 during the movement of the unlocking arm 110 within the slide groove 210, and the limiting part 111 and the clearance opening 230 are not aligned when the movable end of the spring piece 113 abuts against the side wall of the limiting groove 240, the unlocking arm 110 will not disengage from the slide groove 210 on the structural component 2, thus preventing the pull ring 1 from being pulled out. When it is required to remove the pull ring 1 from the structural component 2, only the movable end of the spring piece 113 needs to be pried outward. Move the pull ring 1 so that the movable end of the spring piece 113 does not abut against the side wall of the limiting groove 240 or disengage from the limiting groove 240. Then continue to pull the pull ring 1 outward so that the limiting part 111 on the unlocking arm 110 is aligned with the clearance opening 230. The pull ring 1 can then be removed from the structural component 2. The structural component 2 does not need to be disassembled during this process. Similarly, during assembly, place the two unlocking arms 110 of the pull ring 1 on both sides of the structural component 2 and align the limiting part 111 with the clearance opening 230. Then push the pull ring 1 towards the gold finger end of the structural component 2 so that the spring piece 113 enters the limiting groove 240. The structural component 2 does not need to be disassembled during this process.

[0029] The optical module can be tested without pull ring 1. After the test is completed, pull ring 1 is installed to complete the finished product assembly. If pull ring 1 is not installed during the test and the test module fails, only the top cover needs to be removed. At the same time, the top cover, base and engine can be assembled in advance. Different pull rings 1 can be installed according to different customers. If a customer returns the product and pull ring 1 needs to be replaced and sent to another customer, the pull ring can be replaced without disassembling structural component 2. It is convenient, simple and efficient.

[0030] Example 2

[0031] like Figure 5 , Figure 6 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0032] A pry opening 250 is provided in the slide groove 210, and the pry opening 250 penetrates the side wall of the limiting groove 240 that can abut against the movable end of the spring piece 113. Through the pry opening 250, it is convenient to use a tool to pry the movable end of the spring piece 113 so that the movable end of the spring piece 113 does not abut against the side wall of the limiting groove 240 or is disengaged from the limiting groove 240.

[0033] Example 3

[0034] like Figure 6 As shown, this embodiment is a further improvement on embodiment 1 or 2, as detailed below:

[0035] On the end face of the optical port of the structural component 2, a slot 260 is provided at each corresponding slide groove 210, which is distributed along its length direction. The slot 260 is located on the side of the unlocking arm 110 away from the base 120. The unlocking arm 110 is provided with a stop opening part 114 that enters the slot 260 at the corresponding slot 260. By allowing the stop opening part 114 to enter the slot 260, the pull ring 1 can be prevented from opening outward at the optical port end of the structural component 2.

[0036] Example 4

[0037] like Figure 5 As shown, this embodiment is a further improvement on embodiment 1, 2, or 3, as detailed below:

[0038] The base 220 has grooves 221 distributed along its length direction on the surface of the base 120 facing the pull ring 1. The base 120 of the pull ring 1 is provided with a stop part 121 that enters the groove 221. A return spring 3 is arranged in the groove 221. One end of the return spring 3 abuts against the stop part 121, and the other end of the return spring 3 abuts against the groove wall of the groove 221 away from the limiting part 111. When the pull ring 1 and the structural component 2 are assembled, the return spring 3 will be compressed when the pull ring 1 is pulled outward. If the pull ring 1 is released, the return spring 3 can make the pull ring 1 return to its original position.

[0039] Example 5

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, an optical module includes: an independent pull ring assembly / disassembly structure as described in any of embodiments 1 to 4, which allows the optical module to be tested without the pull ring 1. After the test is completed, the pull ring 1 is finally installed to complete the finished product assembly. If the pull ring 1 is not present during the test, and the test module fails, only the top cover needs to be removed. At the same time, the top cover, base, and engine can be assembled in advance. Different pull rings 1 can be installed according to different customers. If a customer returns the product and the pull ring 1 needs to be replaced and sent to another customer, the pull ring can be replaced without disassembling the structural component 2, which is convenient, simple, and efficient.
