Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of optical fiber communication, and specifically relates to an optical fiber connector. BACKGROUND

[0002] In optical fiber communication, optical fiber connectors are often used to connect with optical fiber adapters on distribution frames to realize the transmission of optical fibers. The existing optical fiber connectors are generally provided with optical fiber connectors that are adaptively connected with optical fiber adapters. The optical fiber connector is slidably connected to the outside of the shell. The optical fiber connector and the optical fiber adapter are locked by the shell. When the optical fiber connector needs to be pulled out, the shell needs to be slid in the direction away from the optical fiber adapter. The locking of the optical fiber connector and the optical fiber adapter is released, so that the optical fiber connector can be pulled out.

[0003] However, since the shell is still in a slidable state after locking, the staff may inadvertently mis-slide the shell during work, causing the optical fiber connector to be mistakenly pulled out of the optical fiber adapter, causing communication interruption and causing the equipment to stop working. UTILITY MODEL CONTENT

[0004] The technical problem to be solved by the utility model is to provide an optical fiber connector that can prevent the optical fiber connector from being mistakenly pulled out of the optical fiber adapter.

DETAILED DESCRIPTION

[0026] The specific embodiments of the utility model are further described below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0027] In the description of the utility model, it should be understood that the terms "upper", "lower", "inner", "outer", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the utility model and simplify the description, and do not indicate or imply that the indicated mechanism or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0028] In the embodiment, the side of the optical fiber connector close to the tail cover is defined as the rear side, and the side of the optical fiber connector away from the tail cover is defined as the front side.

[0029] As shown in Figure 1 The optical fiber connector of the embodiment includes an optical fiber connector 1, an outer shell 2 is slidably connected to the outside of the optical fiber connector 1, a tail cover 4 is connected to the rear side of the optical fiber connector 1, and a lock 3 is sleeved on the tail cover 4.

[0030] As shown in Figure 2 A first protrusion 11 is arranged on the outer surface of the optical fiber connector 1, the first protrusion 11 is located at the rear side of the outer shell 2, and a clamping groove 100 is formed between the first protrusion 11 and the rear end 21 of the outer shell 2.

[0031] As shown in Figure 3As shown, the latch 3 is provided with a latch protrusion 31 adapted to the slot 100. The latch 3 includes a locked state for preventing the outer shell 2 from sliding backward and a non-locked state in which the outer shell 2 can slide freely. The latch 3 includes a connecting body 32, which is sleeved on the tail sleeve 4. A lever part 33 is provided on each side of the connecting body 32, symmetrically arranged on opposite sides of the connector head. The fulcrum of the lever part 33 is located on the connecting body 21. The lever part 33 includes a locking arm 34 extending forward from the fulcrum and a pressing arm 35 extending backward from the fulcrum. By pressing the pressing arm 35, the lever part 33 can swing around the fulcrum. The latch protrusion 31 is located on the inner wall of the two locking arms 34 facing each other, that is, the side of the locking arms 34 facing the slot. It should be noted that providing a pair of lever parts 33 is a preferred embodiment of this embodiment, but only one lever part 33 can also be provided.

[0032] When using the fiber optic connector, the fiber optic connector 1 connects to the external fiber optic adapter and is locked in place by the housing 2. This part is existing technology and will not be described in detail here. Figure 4 As shown, in order to reduce the length of the view, the structure on the rear side of the tail sleeve 4 is omitted. At this time, the latch 3 is in the locked state, and the latch protrusion 31 is located in the slot 100. The rear end 21 of the outer shell 2 is blocked by the latch protrusion 31 and cannot slide backward, which can effectively prevent the staff from accidentally touching the outer shell 2 and causing the fiber optic connector to be accidentally pulled out.

[0033] like Figure 5 As shown, the latch 3 is in the unlocked state at this time, and the latch protrusion 31 is disengaged from the slot 100. Specifically, press the two pressing arms 35 with your fingers; the lever part swings around the fulcrum, causing the two pressing arms 35 to move closer together. Under the action of the lever, the locking arms 34 on the front side of the two lever parts 33 will move away from each other, thus disengaging from the slot 100. Then move the latch 3 backward and place it on the tail sleeve 4. The latch 3 uses a lever structure, which allows the latch protrusion 31 to easily disengage from the slot 100 using leverage, making it more effortless and convenient to use. The connecting body 32 is sleeved on the tail sleeve 4, providing some support to the latch 3 in the locked state, making the locking more stable; and allowing the latch 3 to hang on the tail sleeve 4 in the unlocked state, making it more convenient for future use and less likely to be lost.

[0034] When the latch 3 is in the unlocked state, the rear end 21 of the outer shell 2 is no longer blocked by the latch protrusion 31 and can slide freely to the rear. The width of the slot 100 gradually decreases until the outer shell 2 moves back a sufficient distance to disconnect the fiber optic connector 1 from the fiber optic adapter, thereby pulling out the fiber optic connector.

[0035] like Figure 4 and Figure 5As shown, an elastic element 5 is provided between the fiber optic connector 1 and the outer shell 2. A second protrusion 22 is provided on the inner wall of the outer shell 2, and a third protrusion 12 is provided on the outer surface of the fiber optic connector 1. The third protrusion 12 is located behind the second protrusion 22, and the two ends of the elastic element 5 abut against the second protrusion 22 and the third protrusion 12, respectively. The elastic element 5 can increase the tactile feel of the outer shell 2 when sliding, and can also push the outer shell 2 forward under its own elasticity, and can also prevent the outer shell 2 from accidentally moving backward to a certain extent. In this embodiment, the elastic element 5 is preferably a compression spring.

[0036] like Figure 6 As shown, a pull-out shell 6 is externally connected to the outer shell 2, and the rear end of the pull-out shell 6 is connected to the tail sleeve 4. A fourth protrusion 23 is provided on the outer surface of the outer shell 2, and a barb 61 that mates with the fourth protrusion 23 is provided on the inner wall of the pull-out shell 6. The fourth protrusion 23 is located behind the barb 61. A fifth protrusion 62 is provided on the inner wall of the rear side of the pull-out shell 6, and an annular groove 41 that is adapted to engage with the fifth protrusion 62 is provided on the outer surface of the tail sleeve 4.

[0037] The pull-out housing 6 is designed so that pulling the tail sleeve 4 will cause the pull-out housing 6 to move, and the barb 61 on the pull-out housing 6 will then move the outer shell 2 to the rear, thereby pulling out the fiber optic connector. When multiple fiber optic connectors are densely arranged, it is not easy for fingers to directly contact the outer shell 2. Pulling the tail sleeve 4 can pull out the fiber optic connector, which provides a larger pulling space and makes it easier to pull out.

[0038] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
