In addition, the terms "first" and "second" are only used to distinguish in description and have no special meaning.

[0036] As shown in FIGS. 1-7, the present application provides an optical fiber adapter, which comprises a main body shell 1 having a mounting channel and a shielding door assembly 2 comprising a door body 21 and an elastic member 22, the door body 21 being located in the mounting channel to block the mounting channel; the door body 21 is hinged to the main body shell 1, and the elastic member 22 connects the door body 21 and the main body shell 1; when the optical fiber connector abuts against the door body 21, the door body 21 can be squeezed to rotate and open the mounting channel, so that the elastic member 22 accumulates potential energy to drive the door body 21 to maintain the tendency to block the mounting channel; the side of the door body 21 that receives the abutment of the optical fiber connector is provided with a protective protrusion 23, and when the optical fiber connector abuts against the protective protrusion 23, the protective protrusion 23 is misaligned with the core of the optical fiber connector.

[0037] The side of the door body 21 that receives the abutment of the optical fiber connector is provided with a protective protrusion 23, and when the optical fiber connector abuts against the door body 21, the protective protrusion 23 is misaligned with the core of the optical fiber connector, the protective protrusion 23 contacts the optical fiber connector, the door body 21 does not contact the core of the optical fiber connector, and there is a gap between the door body 21 and the core of the optical fiber connector, thereby not affecting the core of the optical fiber connector, avoiding damage to the core, and thereby avoiding instability after the optical fiber connector is connected.

[0038] Generally, the core of the optical fiber connector is located at the center of the optical fiber connector, as shown in FIGS. 5 and 6, in some embodiments, two protective protrusions 23 are provided, and the two protective protrusions 23 are respectively located on both sides of the center of the door body 21, which can avoid the above-mentioned core on the one hand, and can make the door body 21 bear force evenly when the optical fiber connector abuts against the protective protrusions 23, ensuring the stability of rotation and avoiding the door body 21 from tilting to contact the core.

[0039] In some embodiments, when the fiber joint abuts against the protection protrusion 23, the fiber joint needs to be continuously pushed to the depth of the installation channel for connection. In order to avoid the interference of the protection protrusion 23 to the movement of the fiber joint, the protection protrusion 23 is strip-shaped, which extends from the end of the door body 21 hinged to the main body shell 1 to the other end. That is, when the door body 21 is tipped over by the fiber joint, the extension direction of the protection protrusion 23 at this time is the same as the advancing direction of the fiber joint, thereby avoiding the phenomenon that the fiber joint is blocked by the protection protrusion 23. Exemplarily, the two ends of the protection protrusion 23 are chamfered on the side away from the door body 21, so that the interference with the end angle can be avoided whether the fiber joint is inserted or pulled out.

[0040] As shown in FIG. 2, the inner wall of the main body shell 1 is further provided with a limiting protrusion 3. When the door body 21 abuts against the limiting protrusion 3, the door body 21 blocks the installation channel. Based on this, when the elastic member 22 drives the door body 21 to return and block the installation channel, the limiting protrusion 3 abuts against the door body 21, which can avoid that the door body 21 is excessively abutted and rotated by the potential energy of the elastic member 22.

[0041] As shown in FIGS. 1 to 4, in order to facilitate the installation of the overall fiber adapter, in some embodiments, the main body shell 1 includes an inner shell 11 and an outer shell 12, and the outer shell 12 is sleeved outside the inner shell 11. One of the fiber joints is fixedly inserted at one end of the outer shell 12. When in use, the other fiber joint can be inserted from the other end. Exemplarily, the outer shell 12 and the inner shell 11 are clamped, thereby facilitating the assembly of the main body shell 1. The outer shell 12 is provided with a clamping hole 13, and the inner shell 11 is provided with an elastic clamping block 14, which can be clamped in the clamping hole 13 to fix the inner shell 11 and the outer shell 12. In the present embodiment, the inner shell 11 is provided with a gap 113, and the elastic clamping block 14 includes a connecting plate 141 and a clamping protrusion 142. One end of the connecting plate 141 is connected to the inner wall of the gap 113 and extends along the depth direction of the installation channel. The clamping protrusion 142 is arranged at the other end of the connecting plate 141, so that the inner shell 11 can be pushed into the outer shell 12 from one end of the outer shell 12 for installation. When the clamping protrusion 142 abuts against the inner wall of the outer shell 12, the connecting plate 141 is slightly deformed, and the inner shell 11 is continuously pushed until the clamping protrusion 142 is embedded in the clamping hole 13. In other embodiments, the elastic clamping block 14 can also be directly used as a ball-type positioning pin or other elastic positioning.

[0042] In order to avoid the shaking of the inner shell 11 after installation, maintain the stability of the inner shell 11, the outer side of the inner shell 11 is further provided with a limiting protrusion 15, the inner wall of the outer shell 12 is provided with a clamping groove 16 along the depth direction of the installation channel, the limiting protrusion 15 is embedded and matched with the clamping groove 16, and in order to facilitate the alignment and installation, one end of the clamping groove 16 penetrates the port of the outer shell 12, and then during installation, only the limiting protrusion 15 needs to be aligned with the above-mentioned clamping groove 16, and the inner shell 11 is pushed to complete the installation. The number of limiting protrusions 15 can be set to be multiple, and multiple limiting protrusions 15 are uniformly distributed on the outer side of the inner shell 11.

[0043] As shown in FIGS. 5-7, in some embodiments, the inner shell 11 is provided with an embedded groove 17, and the door body 21 is hinged in the embedded groove 17 through a rotating shaft, so that when the fiber joint opens the door body 21 to enter the installation channel, the door body 21 is placed in the embedded groove 17, and the end face of the protection protrusion 23 is flush with the groove end face of the embedded groove 17, that is, the door body 21 is accommodated in the embedded groove 17, so that the fiber joint can continue to advance and unnecessary interference is reduced. For example, the embedded groove 17 is provided with opposite installation holes, the rotating shaft is inserted into the installation holes, the door body 21 is rotationally connected to the rotating shaft, the elastic member 22 is a torque spring, the torque spring is sleeved on the rotating shaft, and the door body 21 and the groove bottom of the embedded groove 17 are both provided with a mounting groove for mounting the torque spring, so that the door body 21 can smoothly press the torque spring when rotating, so as to accumulate elastic potential energy. In the present embodiment, the mounting groove at the groove bottom of the embedded groove 17 is formed by recessing the groove bottom wall; and the mounting groove on the door body 21 is formed by the clamping protrusions 24 spaced apart on the door body 21, so as to avoid slotting on the door body 21 and avoid affecting the strength of the door body 21. Based on the existence of the clamping protrusions 24, the groove bottom of the mounting groove is provided with a hollow groove 25, so that the clamping protrusions 24 can be embedded in the hollow groove 25, avoiding the clamping protrusions 24 protruding from the mounting groove. The limiting protrusion 3 is located on the inner wall of the inner shell 11.

[0044] As shown in FIG. 4, in some embodiments, in order to facilitate the installation of the door body 21 and the elastic member 22, the inner shell 11 is divided into a first shell part 111 and a second shell part 112, and the first shell part 111 and the second shell part 112 are detachably connected, so that after the door body 21 and the elastic member 22 are installed, the first shell part 111 and the second shell part 112 are connected together to form a complete inner shell 11. The boundary line of the first shell part 111 and the second shell part 112 is not specifically limited. In the present embodiment, one of the first shell part 111 and the second shell part 112 is provided with a clamping block, and the other is provided with a clamping groove, so that the first shell part 111 and the second shell part 112 are clamped with each other to form a complete inner shell 11, and the outer shell 12 is sleeved on the outer side of the first shell part 111 and the second shell part 112, which can stably connect the first shell part 111 and the second shell part 112 together.
