A dustproof lockable structure for an MPO adapter

Abstract

This invention discloses a dustproof and locking structure for an MPO adapter. The MPO adapter's spring arm has a limiting hook, and the insertion part of the MPO lockable dust cover has a limiting groove. When the MPO lockable dust cover is inserted into the MPO adapter, pressing the lock cylinder of the MPO lockable dust cover causes the limiting strip of the lock cylinder to insert into the gap between the MPO adapter's outer shell and the spring arm. This pushes the spring arm to move, causing the limiting hook to engage with the limiting groove of the insertion part, locking the MPO adapter and the MPO lockable dust cover together. Without the pull rod, the lock cylinder of the MPO lockable dust cover cannot be pulled, meaning the MPO adapter and the MPO lockable dust cover cannot be unlocked. The MPO lockable dust cover effectively prevents dust from entering the MPO adapter and affecting network data performance. It also protects the MPO adapter from being arbitrarily inserted by other connectors, preventing data theft. Therefore, the MPO adapter dustproof and locking structure of this invention has the advantages of good security and excellent dustproof effect.

Description

Technical Field

[0001] This invention relates to the field of network communication technology, and in particular to a dustproof and lockable structure for an MPO adapter that offers good security and dustproof performance. Background Technology

[0002] MPO adapters, as common network connection devices, are widely used in fiber-to-fiber connections in network communication. MPO adapters employ a standardized jack latch structure, facilitating insertion and removal. However, in existing technologies, if the MPO adapter port is reserved, it remains open, frequently allowing dust or other impurities to enter, directly affecting its subsequent performance and network communication. Furthermore, the open port also poses a risk of malicious insertion of other connectors, leading to data theft or network intrusion, resulting in complete network security incidents. Therefore, it is necessary to propose an improvement to overcome the shortcomings of the existing technology. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art and provide a dustproof and lockable structure for an MPO adapter that offers good security and dustproof performance.

One end of the device is provided with a limiting wall; when the MPO lockable dust cover is inserted into the MPO adapter, pressing the lock cylinder causes the limiting strip of the lock cylinder to insert into the gap between the spring arm and the outer shell, pushing the spring arm to move away from the outer shell. At this time, the limiting hook cooperates with the limiting groove to lock the MPO adapter and the MPO lockable dust cover together; the end of the pull rod is provided with a hook. When unlocking is required, the pull rod is inserted into the MPO lockable dust cover through the lock hole, and the pull rod is inserted into the protruding part of the lock cylinder. The hook cooperates with the limiting wall of the protruding part. Pulling the pull rod causes the lock cylinder to move away from the MPO adapter, the limiting strip to disengage from the gap between the outer shell and the spring arm, the spring arm to move closer to the outer shell, the limiting hook to disengage from the limiting groove, and the MPO adapter and the MPO lockable dust cover to be unlocked. The MPO lockable dust cover can then be pulled out from the MPO adapter.

[0005] As a preferred technical solution, a limiting block is provided at one end of the protruding part near the MPO adapter, and a sliding groove is provided at one end of the flat part near the MPO adapter corresponding to the protruding part. A limiting baffle is provided at one end of the sliding groove near the receiving cavity.

[0008] As a preferred technical solution, two limiting walls are provided, and two corresponding hooks are also provided.

[0009] This invention discloses a dustproof and lockable structure for an MPO adapter. The MPO adapter's spring arm has a limiting hook, and the insertion part of the MPO lockable dust cover has a limiting groove. When the MPO lockable dust cover is inserted into the MPO adapter, pressing the lock cylinder of the MPO lockable dust cover causes the limiting strip of the lock cylinder to insert into the gap between the MPO adapter's outer shell and the spring arm. This pushes the spring arm to move, causing the limiting hook to engage with the limiting groove of the insertion part, locking the MPO adapter and the MPO lockable dust cover. Without the pull rod, the lock cylinder of the MPO lockable dust cover cannot be pulled, meaning the MPO adapter and the MPO lockable dust cover cannot be unlocked. The MPO lockable dust cover effectively prevents dust from entering the MPO adapter and affecting network data performance. It also protects the MPO adapter from being arbitrarily inserted by other connectors, preventing data theft. Therefore, this invention's MPO adapter dustproof and lockable structure has the advantages of good security and excellent dustproof performance. Attached Figure Description

[0018] like Figure 1 , Figure 2 and Figure 3The image shows a specific embodiment of an MPO adapter dustproof lockable structure according to the present invention. This embodiment of the MPO adapter dustproof lockable structure includes an MPO adapter 1, an MPO lockable dustproof cover 2, and a pull rod 3. The MPO adapter 1 includes a housing 11 and a spring arm 12 disposed within the housing 11. A limit hook 13 is provided at the end of the spring arm 12, and a gap is provided between the housing 11 and the spring arm 12. The other main structures of the MPO adapter 1 in this embodiment are the same as those of existing MPO adapters and will not be described in further detail here. The MPO lockable dust cover 2 includes a main body and a lock cylinder 21. The main body includes an insertion part 22 that inserts into the MPO adapter 1 and a flat part 23 integrally formed with the insertion part 22. The insertion part is provided with a limiting groove 24 corresponding to the limiting hook 13 of the spring arm 12 of the MPO adapter 1. The flat part 23 is provided with a receiving cavity 25 for receiving the lock cylinder 21 at the end away from the MPO adapter 1. The lock cylinder 21 is received in the receiving cavity 25 and can slide within the receiving cavity 25. The lock cylinder 21 includes a limiting strip 21a and a protruding part 21b.

The protruding part 21b of the lock cylinder 21 extends into the flat part 23. The protruding part 21b is provided with a lock hole 21c for inserting a pull rod 3. The end of the protruding part 21b near the MPO adapter 1 is provided with a limiting wall 21d. When the MPO lockable dust cover 2 is inserted into the MPO adapter 1, the lock cylinder 21 is pressed. The limiting strip 21a of the lock cylinder 21 is inserted into the gap between the outer shell 11 and the spring arm 12 of the MPO adapter 1, pushing the spring arm 12 to move away from the outer shell 11, and engaging the limiting hook 13 with the limiting groove 24. The limiting hook 13 and the limiting groove 24 cooperate to lock the MPO adapter 1 and the MPO lockable dust cover 2. At this time, the end of the lock cylinder 21 away from the MPO adapter 1 is flush with the end of the flat part 23 away from the MPO adapter, preventing others from pulling out the lock cylinder 21 by pinching it. The end of the lever 3 is provided with a hook 31. When unlocking is required, the lever 3 is inserted into the MPO lockable dust cover 2 through the lock hole 21c. The hook 31 is inserted into the protruding part 21b of the lock cylinder 21 and engages with the limiting wall 21d. Pulling the lever 3 moves the lock cylinder 21 away from the MPO adapter 1. The limiting strip 21a disengages from the gap between the outer shell 11 and the spring arm 12. The spring arm 12 moves towards the outer shell 11. The limiting hook 13 on the spring arm 12 disengages from the limiting groove 24 on the insertion part 22. The MPO adapter 1 and the MPO lockable dust cover are unlocked. At this time, the MPO lockable dust cover 2 can be pulled out from the MPO adapter 1.The present invention discloses an MPO adapter dustproof locking structure. When the lock cylinder is pushed to lock the MPO adapter and the MPO locking dustproof cover, the MPO locking dustproof cover cannot be pulled out of the MPO adapter without a pull rod. The MPO locking dustproof cover can effectively prevent dust from entering the inside of the MPO adapter and affecting network data performance. It can also protect the MPO adapter from being arbitrarily inserted by other connectors and prevent data theft.

A limiting wall 23c is provided at the end of the groove 23b near the receiving cavity 25. The groove 23b can ensure that the lock cylinder 21 slides within the receiving cavity of the flat part 23, and the limiting block 21e cooperates with the limiting wall 23c to prevent the lock cylinder 21 from disengaging from the flat part 23 and being pulled out.

[0020] To ensure the locking effect between the MPO adapter 1 and the MPO lockable dust cover 2, in this embodiment, two spring arms 12 are provided, two limit hooks 13 are also provided, and two limit grooves 24 of the insertion part 22 are also provided accordingly. Correspondingly, two limit strips 21a of the lock cylinder 21 are also provided, and two openings 23a of the flat part 23 are also provided.

[0021] In order to ensure the pulling force of the lever 3 on the lock cylinder 21, in this embodiment, two limiting walls 21d of the lock cylinder 21 are provided, and two hooks 31 of the lever 3 are also provided.

[0022] This invention discloses a dustproof and lockable structure for an MPO adapter. The MPO adapter's spring arm has a limiting hook, and the insertion part of the MPO lockable dust cover has a limiting groove. When the MPO lockable dust cover is inserted into the MPO adapter, pressing the lock cylinder of the MPO lockable dust cover causes the limiting strip of the lock cylinder to insert into the gap between the MPO adapter's outer shell and the spring arm. This pushes the spring arm to move, causing the limiting hook to engage with the limiting groove of the insertion part, locking the MPO adapter and the MPO lockable dust cover. Without the pull rod, the lock cylinder of the MPO lockable dust cover cannot be pulled, meaning the MPO adapter and the MPO lockable dust cover cannot be unlocked. The MPO lockable dust cover effectively prevents dust from entering the MPO adapter and affecting network data performance. It also protects the MPO adapter from being arbitrarily inserted by other connectors, preventing data theft. Therefore, this invention's MPO adapter dustproof and lockable structure has the advantages of good security and excellent dustproof performance.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention.
