DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figures 1-9 , an MPO connector sheath unlocking device, comprising a ferrule assembly and a dust cap 1 connected to the ferrule assembly, a shell 2 being sleeved on the ferrule assembly, and a sheath 3 being connected to an end of the shell 2 away from the dust cap 1;

[0032] Reference Figure 2 The ferrule assembly includes a housing 4, a connecting block 5 is fixedly mounted on one end of the housing 4, and a ferrule module 6 is provided on the end of the connecting block 5 away from the housing 4; a first connecting member 7 and a second connecting member 8 are sequentially provided on the end of the housing 4 away from the connecting block 5, and the first connecting member 7 and the second connecting member 8 are threadedly connected; a return spring 9 is provided in the first connecting member 7, one end of the return spring 9 is connected to the connecting block 5, and the other end of the return spring 9 is connected to the first connecting member 7;

[0033] Reference Figure 2The end of the sheath 3 away from the shell 2 is nested and connected with a soft rubber sleeve 10, and an optical cable 11 is provided inside the soft rubber sleeve 10. One end of the optical cable 11 is connected to the core assembly, and the other end of the optical cable 11 passes through the first connector 7, the second connector 8 and the soft rubber sleeve 10 in sequence and extends to the outside of the soft rubber sleeve 10, and the inner wall of the soft rubber sleeve 10 is fixedly connected to the surface of the optical cable 11.

[0034] In this embodiment, the MPO connector is connected to an external plug interface using a connection block 5 and a ferrule module 6, thereby communicating signals. The first connector 7 and the second connector 8 are used to connect the housing 4 to the optical cable 11. When the MPO connector needs to be reset, the ferrule assembly is reset by a reset spring 9. By connecting the rear sheath 3 of the connector to the front housing 2, in high-density environments, pushing and pulling the rear sheath 3 drives the housing 2, which in turn drives the entire front MPO connector to move, thereby achieving connection and unlocking.

[0035] Reference Figure 2-Figure 3 、 Figure 9 Specifically, the upper and lower surfaces of the shell 4 are respectively provided with a first protrusion 4-1 and a second protrusion 4-2, and a first slide groove 4-3 is formed between the first protrusion 4-1 and the second protrusion 4-2; the front and rear surfaces of the shell 4 are provided with a first bayonet 4-4, and small springs 12 are provided between the front and rear surfaces of the shell 4 and the inner wall of the shell 2. When the MPO connector needs to be reset, the two small springs 12 enable the shell 2, the shell 4, etc. to rebound and reset.

[0036] Reference Figure 4 Specifically, the front and rear surfaces of the first connecting member 7 close to one end of the connecting block 5 are both provided with a first clamping block 7 - 1 , and the first clamping block 7 - 1 can be clamped with the first bayonet 4 - 4 on the shell 4 .

[0037] Reference Figure 2 、 Figure 6 Specifically, the upper and lower surfaces of the inner wall of the housing 2 are both provided with a first slider 2-1. The first slider 2-1 can slide within the first chute 4-3, and the first slider 2-1 and the first protrusion 4-1 are in planar contact, and the first slider 2-1 and the second protrusion 4-2 are in oblique contact. Here, when the housing 2 moves, the first slider 2-1 can slide within the first chute 4-3 and can perfectly cooperate with the first protrusion 4-1 and the second protrusion 4-2.

[0038] Reference Figure 6 Specifically, the upper and lower surfaces of the shell 2 are both provided with groove surfaces 2-2, and the end of the groove surface 2-2 close to the sheath 3 is provided with a protrusion 2-3.

[0039] Reference Figure 7 Specifically, the upper and lower surfaces of the sheath 3 are each provided with a first notch 3-1. The end of the sheath 3 away from the soft rubber cover 10 is nested with the groove surface 2-2 of the housing 2, and the sheath 3 is flush with the surface of the protrusion 2-3. When the sheath 3 is nested with the housing 2, the end of the sheath 3 mates with the groove surface 2-2 of the housing 2, which not only looks good but also drives the housing 2 to move when the sheath 3 moves.

[0040] Reference Figure 7 Specifically, the front and rear surfaces of the sheath 3 are both provided with a second notch 3-2.

[0041] Reference Figure 8 Specifically, an arc block 10 - 1 is provided at the connection between the soft rubber sleeve 10 and the sheath 3 .

[0042] In this embodiment, the first notch 3-1 or the second notch 3-2 is used to facilitate the push-pull movement of the sheath 3, making it easy to operate and use. There are two arc blocks 10-1, which are symmetrically arranged. When the sheath 3 moves, the arc blocks 10-1 facilitate the movement of the soft rubber sheath 10 and the optical cable 11 as a whole.

[0043] In this embodiment, when the MPO connector is unlocked, the sleeve 3 is pushed and pulled, driving the housing 2 to which it is connected. Since the housing 2 is connected to the outer shell 4, the housing 2 moves, and the front connection block 5, ferrule module 6, etc. move. Since the first clamping block 7-1 is engaged with the first clamping hole 4-4 on the outer shell 4, the first connecting member 7 moves, and ultimately drives the second connecting member 8, soft rubber sleeve 10, and optical cable 11 to move as a whole, achieving unlocking. The reset spring 9 resets the ferrule assembly; the two small springs 12 make the housing 2, outer shell 4, etc. rebound and reset, thereby resetting the MPO connector.

[0044] In summary, the present invention connects the sleeve at the rear end of the connector to the housing at the front end, and can achieve connection and unlocking in a high-density environment by pushing and pulling the rear end sleeve.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
