Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to an MPO connector with a locking device. Background Technology

[0002] With the increasing demand for communication bandwidth, optical fiber has been widely used in wired communication networks. Existing MPO fiber optic connectors are connected to external adapters. When the external adapter is adapted to the MPO connector, the adapter is fitted onto the outside of the outer frame. The outer frame and the connector body are movable. When the adapter needs to be removed, the outer frame can be moved to remove the adapter. However, because the outer frame and the connector body are movable, the connection signal between the MPO and the adapter is unstable. Therefore, the outer frame and the connector body need to be stably fixed to ensure the stability of the connector signal. At the same time, the outer frame and the connector body should be movable when needed to facilitate the insertion and removal of the adapter. This utility model is designed to solve the above problems. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an MPO connector with a locking device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an MPO connector with a locking device, including a wire body composed of an optical cable wrapped by a wire sleeve, and a connecting body connected to the wire body, a tail sleeve sleeved on the lower part of the connecting body and the outside of the wire body, an outer frame sleeved on the connecting body, and an unlocking member limited between the outside of the connecting body and the inside of the outer frame. A gap is provided between the outside of the connecting body and the inside of the outer frame, and the outer frame is provided with an unlocking hole communicating with the gap and in which the unlocking member can move.

[0005] Preferably, the outer frame includes a first side and a second side, the inner side of the second side is provided with a first avoidance blind groove, the first avoidance blind groove forms a gap with the outer side of the connecting body, the unlocking hole is provided on the second side, the unlocking hole is located in the area of ​​the first avoidance blind groove and communicates with the first avoidance blind groove.

[0006] Preferably, the unlocking hole is a rectangular hole, which is divided into a locking area and a releasing area. The short side of the unlocking hole in the releasing area has a protrusion facing the center of the hole, and the second side has a clearance hole located next to the protrusion.

[0007] Preferably, the unlocking component includes an unlocking body in the shape of a cuboid and a cuboid gripping position fixed on the upper side of the unlocking body. The unlocking body and the gripping position form a ┛ shape, and the two ends of the gripping position are provided with protrusions.

[0008] Preferably, the inner side of the first side of the outer frame is provided with a second limiting blind groove and a third limiting blind groove that enter from both ends of the outer frame respectively, and the inner side of the second side is provided with a fourth limiting blind groove. The first avoiding blind groove and the fourth limiting blind groove enter from both ends of the outer frame respectively. The outer side of the connecting body is provided with a first fastening position, a second fastening position, a third fastening position, and a fourth fastening position that correspond to the first avoiding blind groove, the second limiting blind groove, the third limiting blind groove, and the fourth limiting blind groove.

[0009] The beneficial effect of this utility model is that it provides an MPO connector with a locking device. In application, the user holds the gripping part and pushes the unlocking body towards the locking area, causing the unlocking body to enter the gap between the first avoidance blind groove and the connecting body. The gap is completely filled by the unlocking body, meaning the unlocking part is in a locked state, and the outer frame cannot move outside the connecting body. If the outer frame needs to move outside the connecting body, the user simply holds the gripping part and moves the unlocking body towards the loosening area, causing the unlocking body to leave the gap. At this time, because there is a gap between the outer frame and the connecting body, there is no other constraint, so the outer frame can move outside the connecting body. Therefore, when the unlocking part is in the unlocked state, the outer frame can move up and down, making this utility model easy to adapt to external adapters. When the unlocking part is in the locked state, it also ensures that the outer frame is stably fixed to the outside of the connecting body. The stability of the outer frame ensures that the adapter is also stable when adapted to this utility model, thus ensuring the stability of the connection signal. The range of the upper and lower movement of the outer frame is limited to avoid excessive movement that could affect the internal connection structure of the connecting body.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Reference Figures 1 to 10The present invention is implemented as follows: An MPO connector with a locking device includes a cable body 1 consisting of an optical cable wrapped with a cable sleeve, a connecting body 2 connected to the cable body 1, a tail sleeve 3 sleeved on the lower part of the connecting body 2 and the outside of the cable body 1, an outer frame 4 sleeved on the middle part of the connecting body 2, and an unlocking member 5 limited between the outer side of the connecting body 2 and the inner side of the outer frame 4. A gap 6 is provided between the outer side of the connecting body 2 and the inner side of the outer frame 4, and the outer frame 4 is provided with an unlocking hole 41 communicating with the gap 6. The unlocking member 5 can move within the unlocking hole 41.

[0023] When this utility model is applied, the unlocking member 5 is moved within the unlocking hole 41, causing the unlocking member 5 to move out of the gap 6, so that the outer frame 4 can move on the outside of the connecting body 2 to facilitate adaptation with the external adapter 001. After adaptation, the unlocking member 5 is moved back into the gap 6, and the gap 6 between the outer frame 4 and the connecting body 2 is filled by the unlocking member 5, thereby fixing the outer frame 4 on the outside of the connecting body 2.

[0024] Thus, this utility model can satisfy the following: the outer frame 4 can move on the outside of the connecting body 2, making it easy to adapt to the adapter 001. After the adapter 001 is adapted and connected to this utility model, the outer frame 4 can also be stably fixed on the outside of the connecting body 2, thereby ensuring the stability of the connector signal.

[0025] Based on the above embodiments, as a further preferred embodiment, the outer frame 4 includes a first side 42 and a second side 43. The inner side of the second side 43 is provided with a first avoidance blind groove 431. A gap 6 is formed between the first avoidance blind groove 431 and the outer side of the connecting body 2. The second side 43 is also provided with an unlocking hole 41. The unlocking hole 41 is located in the area of ​​the first avoidance blind groove 431 and communicates with the first avoidance blind groove 431.

[0026] The unlocking hole 41 is a rectangular hole, which is divided into two parts: a locking area 411 and a releasing area 412. The short side of the unlocking hole 41 is located in the area of ​​the releasing area 412 and has a protrusion 4121 facing the center of the hole. The second side 43 has a clearance hole 433 located next to the protrusion 4121.

[0027] The unlocking component 5 includes an unlocking body 51 in the shape of a cuboid and a cuboid gripping position 52 fixed on the upper side of the unlocking body 51. The unlocking body 51 and the gripping position 52 form a ┛ shape, and the two ends of the gripping position 52 are provided with protrusions 521.

[0028] During installation, the outer frame 4 is fitted onto the outside of the connecting body 2, and the unlocking element 5 is placed inside the unlocking hole 41. At this time, the gripping position 52 is located in the loosening area, and the unlocking body 51 is located in the locking area 411. That is, the unlocking element 5 is in the unlocked state. When the position of the outer frame 4 and the connecting body 2 needs to be fixed and moved, the user holds the gripping position 52 and pushes the unlocking body 51 toward the locking area 411, so that the unlocking body 51 enters the gap 6 between the first avoidance blind groove 431 and the connecting body 2. The gap 6 is completely filled by the unlocking body 51. Therefore, the outer frame 4 cannot move outside the connecting body 2. That is, the unlocking element 5 is in the locked state. If the outer frame 4 needs to move outside the connecting body 2, the user only needs to hold the gripping position 52 and push the unlocking body 51 toward the loosening area, so that the unlocking body 51 leaves the gap 6. At this time, the outer frame 4 and the connecting body 2 lack constraint because of the gap 6, so the outer frame 4 can move outside the connecting body 2.

[0029] In the unlocked state, the gripping part 5 is pushed towards the loosening area 412. The two protrusions 521 at both ends of the gripping part 52 abut against the protrusion 4121 in the loosening area, thereby ensuring that the unlocking part 5 is fixed in the unlocking hole 41 in the unlocked state. When the gripping part 52 of the unlocking part 5 moves towards the locking area 411, the protrusion 521 forcibly passes over the protrusion 4121. The second side 43 is provided with a clearance hole 433 located next to the protrusion 4121. The clearance hole 433 provides a buffer space for the protrusion 521 to pass over the protrusion 4121.

[0030] In summary, when the unlocking component 5 is in the unlocked state, the outer frame 4 can move up and down, making it easy for this utility model to be adapted to the external adapter 001. When the unlocking component 5 is in the locked state, it can also ensure that the outer frame 4 is stably fixed to the outside of the connecting body 2. The stability of the outer frame 4 ensures that the adapter 001 is also stable when adapted to this utility model, thereby ensuring the stability of the connection signal.

[0031] Based on the above embodiments, as a further preferred embodiment, the inner side of the first side 42 of the outer frame 4 is provided with a second limiting blind groove 421 and a third limiting blind groove 422 that enter from both ends of the outer frame 4, and the inner side of the second side 43 is provided with a fourth limiting blind groove 434. The first avoiding blind groove 431 and the fourth limiting blind groove 434 enter from both ends of the outer frame 4, and the outer side of the connecting body 2 is provided with a first fastening position 21, a second fastening position 22, a third fastening position 23, and a fourth fastening position 24 that correspond to the first avoiding blind groove 431, the second limiting blind groove 421, the third limiting blind groove 422, and the fourth limiting blind groove 434.

[0032] In this utility model's MPO connector structure, springs are provided between the outer frame 4 and both sides of the connecting body 2. The movement range of the outer frame 4 cannot be too large; otherwise, the springs will bounce out due to the loss of the constraint of the outer frame 4. The outer frame 4 is sleeved on the outside of the connecting body 2. When the unlocking member 5 is in the unlocked state, the outer frame 4 can move up and down on the outside of the connecting body 2. During the up and down movement, the first fastening position 21 engages with the first avoidance blind groove 431, the second fastening position 22 engages with the second limit blind groove 421, the third fastening position 23 engages with the third limit blind groove 422, and the fourth fastening position 24 engages with the fourth limit blind groove 434, thereby limiting the range of up and down movement of the outer frame 4 on the outside of the connecting body 2.

[0033] When plugging or unplugging the external adapter 001, only a slight movement of the outer frame 4 is required. There is no need for excessive movement or concern that the movement of the outer frame 4 may affect the internal connection structure of the main body 2.

[0034] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
