Description

Technical Field

[0001] The invention relates to the technical field of communications, and in particular to an MPO connector with a locking device. Background Art

[0002] With the increasing demand for communication bandwidth, optical fiber has been widely used in wired communication networks. The existing MPO optical fiber connector is connected to an external adapter when used. When the external adapter is adapted to the MPO connector, the adapter is sleeved on the outside of the outer frame. The outer frame and the connection body are movable. When the adapter needs to be unplugged, the outer frame can be moved to unplug the adapter. However, because the outer frame and the connection body are movable, the connection signal between the MPO and the adapter is unstable. Therefore, the outer frame and the connection body must be stably fixed to ensure the stability of the connector signal. At the same time, when necessary, the outer frame connection body must be movable to facilitate the plugging and unplugging of the adapter. The present invention is to solve the above problems. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides an MPO connector with a locking device.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an MPO connector with a locking device, including a wire body composed of a wire sleeve wrapped around an optical cable, and also including a connecting body connected to the wire body, a tail sleeve sleeved on the lower part of the connecting body and the outer side of the wire body, an outer frame sleeved on the connecting body, and an unlocking piece defined between the outer side of the connecting body and the inner side of the outer frame, a gap is provided between the outer side of the connecting body and the inner side of the outer frame, and the outer frame is provided with an unlocking hole communicated with the gap and in which the unlocking piece can move.

[0005] Preferably, the outer frame includes a first side surface and a second side surface, the inner side of the second side surface is provided with a first blind groove avoiding the ...

[0006] Preferably, the unlocking hole is set as a rectangular hole, and the unlocking hole of the rectangular hole is divided into two parts, namely a locking area and a loosening area. The short side of the unlocking hole of the rectangular hole located in the loosening area is provided with a protrusion facing the center of the hole, and the second side surface is provided with a yield hole located next to the protrusion.

[0007] Preferably, the unlocking member includes an unlocking body arranged in a rectangular parallelepiped shape and a rectangular parallelepiped gripping position fixed on the upper side of the unlocking body, the unlocking body and the gripping position form a ┛ shape, and protrusions are provided at both ends of the gripping position.

[0008] Preferably, the inner side of the first side surface of the outer frame is provided with a second limiting blind groove and a third limiting blind groove respectively entering from the two ends of the outer frame, the inner side of the second side surface is provided with a fourth limiting blind groove, the first avoiding blind groove and the fourth limiting blind groove respectively enter from the two ends of the outer frame, and the outer side of the connecting body is provided with a first buckle position, a second buckle position, a third buckle position, and a fourth buckle position corresponding 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 the present invention is to provide an MPO connector with a locking device. When used, the user holds the gripping position to drive the unlocking body toward the locking area, so that the unlocking body enters the gap between the first blind groove and the connecting body, and the gap is completely filled by the unlocking body, that is, the unlocking member is in a locked state at this time, and the outer frame cannot move outside the connecting body. If the outer frame needs to be able to move outside the connecting body, it is only necessary for the user to hold the gripping position to drive the unlocking body to move toward the slack area, so that the unlocking body leaves the gap. At this time, there is a gap between the outer frame and the connecting body and there are no other constraints, so the outer frame can move outside the connecting body. Therefore, when the unlocking member is in the unlocking state, the outer frame can move up and down, so that the present invention can be easily adapted to the external adapter. When the unlocking member is in the locking state, it can also meet the requirements of the outer frame being stably fixed and connected to the outside of the connecting body. The stability of the outer frame ensures that the adapter is also stable when adapted to the present invention, thereby ensuring the stability of the connection signal. The amplitude of the up and down movement of the outer frame is limited to avoid the outer frame moving too much and affecting the internal connection structure of the connecting body.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

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

[0023] When the present invention is used, the unlocking member 5 is moved in the unlocking hole 41 so that the unlocking member 5 moves out of the gap 6, allowing the outer frame 4 to move on the outside of the connecting body 2 to facilitate adaptation with the external adapter 001. After the adaptation is completed, 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, so that the outer frame 4 is fixed on the outside of the connecting body 2.

[0024] Therefore, the present invention can satisfy that the outer frame 4 can be movable outside the connecting body 2 to facilitate adaptation with the adapter 001. After the adapter 001 is adapted and connected with the present invention, the outer frame 4 can also be stably fixedly connected to the outside of the connecting body 2, thereby ensuring the stability of the connector signal.

[0025] On the basis of the above embodiment, as a further preference, the outer frame 4 includes a first side surface 42 and a second side surface 43, the inner side of the second side surface 43 is provided with a first blind groove avoidance 431, a gap 6 is formed between the first blind groove avoidance 431 and the outer side of the connecting body 2, the second side surface 43 is also provided with an unlocking hole 41, the unlocking hole 41 is arranged in the area of ​​the first blind groove avoidance 431 and communicates with the first blind groove avoidance 431.

[0026] The unlocking hole 41 is set as a rectangular hole, and the unlocking hole 41 of the rectangular hole is divided into two parts, namely a locking area 411 and a loosening area 412. The short side of the unlocking hole 41 of the rectangular hole is located in the area of ​​the loosening area 412 and is provided with a protrusion 4121 facing the center of the hole, and the second side surface 43 is provided with a yield hole 433 located next to the protrusion 4121.

[0027] The unlocking member 5 includes an unlocking body 51 in a rectangular shape and a rectangular gripping portion 52 fixed on the upper side of the unlocking body 51 . The unlocking body 51 and the gripping portion 52 form a ┛ shape, and protrusions 521 are provided at both ends of the gripping portion 52 .

[0028] During installation, the outer frame 4 is sleeved on the outer side of the connecting body 2, and the unlocking piece 5 is placed in the unlocking hole 41. At this time, the gripping position 52 is located in the loose area, and the unlocking body 51 is located in the locking area 411, that is, the unlocking piece 5 is in the unlocking state at this time. When the position fixing part of the outer frame 4 and the connecting body 2 needs to move, the user holds the gripping position 52 to drive the unlocking body 51 to push toward the locking area 411, so that the unlocking body 51 enters the gap 6 between the first avoiding blind groove 431 and the connecting body 2, and the gap 6 is completely filled by the unlocking body 51. Therefore, the outer frame 4 cannot move on the outside of the connecting body 2, that is, the unlocking piece 5 is in the locked state at this time. If the outer frame 4 needs to be able to move on the outside of the connecting body 2, the user only needs to hold the gripping position 52 to drive the unlocking body 51 to move toward the loose area, so that the unlocking body 51 leaves the gap 6. At this time, there is no constraint between the outer frame 4 and the connecting body 2 due to the gap 6, so the outer frame 4 can move on the outside of the connecting body 2.

[0029] When in the unlocked state, the unlocking member 5 is grasped and pushed toward the loosening area 412, and the protrusions 521 at both ends of the grasping position 52 conflict with the protrusion 1 4121 in the loosening area, thereby ensuring that the unlocking member 5 is fixed in the unlocking hole 41 and does not move when in the unlocked state. When the grasping position 52 of the unlocking member 5 fluctuates toward the locking area 411, the protrusion 2 521 forcibly passes over the protrusion 1 4121, and the second side surface 43 is provided with a clearance hole 433 located next to the protrusion 1 4121, and the clearance hole 433 provides a buffer space for the protrusion 2 521 to pass over the protrusion 1 4121.

[0030] In summary, when the unlocking member 5 is in the unlocked state, the outer frame 4 can move up and down, so that the present invention can be easily adapted to the external adapter 001. When the unlocking member 5 is in the locked state, the outer frame 4 can also be stably fixedly connected 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 the present invention, thereby ensuring the stability of the connection signal.

[0031] On the basis of the above embodiments, as a further preference, the inner side of the first side surface 42 of the outer frame 4 is provided with a second limiting blind groove 421 and a third limiting blind groove 422 which enter from the two ends of the outer frame 4 respectively, the inner side of the second side surface 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 the two ends of the outer frame 4 respectively, and the outer side of the connecting body 2 is provided with a first buckle position 21, a second buckle position 22, a third buckle position 23, and a fourth buckle position 24 corresponding 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 the MPO connector structure of the present invention, a spring is provided between the outer frame 4 and both sides of the connection body 2, and the movement range of the outer frame 4 cannot be too large, otherwise the spring will bounce out due to the loss of the constraint of the outer frame 4. The outer frame 4 is sleeved on the outer side of the connection body 2, and when the unlocking member 5 is in the unlocked state, the outer frame 4 can move up and down on the outer side of the connection body 2. During the up and down movement, the first buckle position 21 is buckled with the first avoiding blind groove 431, the second buckle position 22 is buckled with the second limiting blind groove 421, the third buckle position 23 is buckled with the third limiting blind groove 422, and the fourth buckle position 24 is buckled with the fourth limiting blind groove 434, thereby limiting the range of the outer frame 4 moving up and down on the outer side of the connection body 2.

[0033] When plugging or unplugging the external adapter 001 , it is only necessary to slightly move the outer frame 4 , without excessive movements or worrying about the outer frame 4 moving too much and affecting the internal connection structure of the connection body 2 .

[0034] It should be noted that for the preferred embodiments of the present invention, ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
