Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to an optical fiber adapter. Background Art

[0002] The optical fiber adapter is used to connect two optical fiber connectors. Generally, one optical fiber connector is fixed at one end of the optical fiber adapter. When it is necessary to connect the optical fibers, the other optical fiber connector is inserted into the other end of the optical fiber adapter for connection;

[0003] Since the optical fiber connector fixed on the optical fiber adapter can emit communication light, and the communication light has the characteristic of high energy, which cannot be recognized by the human eye. When another optical fiber connector is not inserted into the optical fiber adapter, the emitted communication light can damage the human eye; and when another optical fiber connector is not inserted, dust and other impurities are likely to accumulate in the optical fiber adapter, and the dust and other impurities will interfere with the connection of the two optical fiber connectors, thus causing potential use risks;

[0004] To solve the above problems, a shielding door is generally used in the prior art. When in use, the optical fiber connector abuts against the shielding door. Due to the way of being pushed by the optical fiber connector, the core of the optical fiber connector is easily damaged, and the connection is likely to be unstable after connection. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an optical fiber adapter to solve the problem of easily damaging the core of the optical fiber connector.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0010] When the optical fiber connector abuts against the door body, the door body can be squeezed to rotate and open the installation channel, so that the elastic member stores potential energy to drive the door body to maintain the tendency of blocking the installation channel;

[0011] A protection protrusion is provided on the side of the door body that receives the abutment of the optical fiber connector. When the optical fiber connector abuts against the protection protrusion, the protection protrusion is misaligned with the core of the optical fiber connector.

[0013] In some embodiments, the protection protrusion is strip-shaped and extends from the end where the door body is hinged to the main body shell to the other end.

[0014] In some embodiments, a limiting protrusion is arranged inside the main body shell. When the door body abuts against the limiting protrusion, the door body blocks the installation channel.

[0015] In some embodiments, the main body shell includes an inner shell and an outer shell. The outer shell is sleeved outside the inner shell, and the inner shell is snap-connected to the outer shell.

[0016] In some embodiments, the outer shell is provided with a card hole, and the inner shell is provided with an elastic card block, and the elastic card block can be snap-connected into the card hole.

[0021] Advantages of the present utility model:

[0022] A protection protrusion is arranged on the side of the door body that receives the abutment of the optical fiber connector. When the optical fiber connector abuts against the door body, the protection protrusion is misaligned with the core of the optical fiber connector. The protection protrusion contacts the optical fiber connector, and the core of the optical fiber connector does not contact the door body, and there is a gap between the two, so that the core of the optical fiber connector will not be affected, and damage to the core is avoided, thereby avoiding the unstable phenomenon after the connection of the optical fiber connector.

[0034] The following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model rather than all structures are shown in the drawings.

[0035] In the description of the present utility model, unless otherwise clearly specified and defined, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0037] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] As Figures 1 to 7 shown, the present utility model provides an optical fiber adapter, which includes a main body shell 1 and a shielding door assembly 2. The main body shell 1 has an installation channel. The shielding door assembly 2 includes a door body 21 and an elastic member 22. The door body 21 is located in the installation channel to block the installation 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, it can squeeze the door body 21 to rotate and open the installation channel, so that the elastic member 22 stores potential energy to drive the door body 21 to maintain the tendency of blocking the installation channel. A protection protrusion 23 is arranged on the side of the door body 21 that receives the abutment of the optical fiber connector. When the optical fiber connector abuts against the protection protrusion 23, the protection protrusion 23 is misaligned with the core of the optical fiber connector.

[0039] A protection protrusion 23 is arranged on the side of the door body 21 that receives the abutment of the optical fiber connector. And when the optical fiber connector abuts against the door body 21, the protection protrusion 23 is misaligned with the core of the optical fiber connector. The protection protrusion 23 contacts the optical fiber connector, and the door body 21 does not contact the core of the optical fiber connector. There is a gap between them, and thus it will not affect the core of the optical fiber connector, avoiding damage to the core, and thereby avoiding the unstable phenomenon after the connection of the optical fiber connector.

[0040] Generally, the core of an optical fiber connector is located at the center of the optical fiber connector, as Figure 5 and Figure 6As shown, in some embodiments, two protective protrusions 23 are provided, and the two protective protrusions 23 are located on both sides of the center of the door body 21. On the one hand, they can avoid the above-mentioned fiber core; on the other hand, when the optical fiber connector hits the protective protrusion 23, the door body 21 can be evenly stressed, ensuring the stability of the rotation and preventing the door body 21 from tilting and contacting the fiber core.

[0041] In some embodiments, after the optical fiber connector abuts the above-mentioned protective protrusion 23, it is necessary to continue to push the optical fiber connector to the depth of the installation channel for connection; and in order to avoid the interference of the protective protrusion 23 on the moving operation of the optical fiber connector, the protective protrusion 23 is strip-shaped, extending from one end of the door body 21 and the main shell 1 to the other end, that is, when the door body 21 is knocked down by the optical fiber connector, the extension direction of the protective protrusion 23 is the same as the forward direction of the optical fiber connector, thereby avoiding the phenomenon that the optical fiber connector is blocked by the protective protrusion 23. Furthermore, the two ends of the protective protrusion 23 are chamfered away from the door body 21, so that whether the optical fiber connector is plugged in or unplugged, it can avoid interference with the end angle.

[0042] like Figure 2 As shown, the inner wall of the main body shell 1 is also provided with a limiting protrusion 3, and when the door body 21 abuts against the limiting protrusion 3, the door body 21 blocks the installation passage. Based on this, when the elastic member 22 drives the door body 21 to return and block the installation passage, the limiting protrusion 3 abuts against the door body 21, which can prevent the door body 21 from being excessively pressed and rotated by the potential energy of the elastic member 22.

[0043] like Figures 1 to 4 As shown, in order to facilitate the installation of the overall optical fiber adapter, in some embodiments, the main shell 1 includes an inner shell 11 and an outer shell 12, and the outer shell 12 is sleeved on the outside of the inner shell 11; one of the optical fiber connectors is fixedly plugged into one end of the outer shell 12; when in use, it is only necessary to insert the other optical fiber connector from the other end. Specifically, the outer shell 12 and the inner shell 11 are arranged to be snap-fitted, so as to facilitate the assembly of the main shell 1. More specifically, a snap-fitting hole 13 is provided on the outer shell 12, and an elastic snap-fitting block 14 is provided on the inner shell 11, and the elastic snap-fitting block 14 can be snap-fitted into the snap-fitting hole 13 to fix the inner shell 11 and the outer shell 12. In the current embodiment, the inner shell 11 is provided with a notch 113, and the elastic 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 notch 113 and extends along the depth direction of the installation channel, and the clamping protrusion 142 is provided at the other end of the connecting plate 141, so that the inner shell 11 can be pushed from one end of the outer shell 12 into the outer shell 12 for installation, wherein 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 some other embodiments, the elastic block 14 can also directly adopt other elastic positioning such as ball-type positioning pins.

[0044] To avoid the shaking of the inner shell 11 after installation and maintain the stability of the inner shell 11, a limiting protrusion 15 is further provided on the outer side of the inner shell 11, and a clamping groove 16 along the depth direction of the installation channel is provided on the inner wall of the outer shell 12. The limiting protrusion 15 is in embedded fit with the clamping groove 16. In order to facilitate alignment during installation, one end of the clamping groove 16 penetrates through the port of the outer shell 12. Thus, during installation, only the limiting protrusion 15 needs to be aligned with the above-mentioned clamping groove 16, and the inner shell 11 can be pushed to complete the installation. The number of the limiting protrusions 15 can be set to multiple, and they are evenly distributed on the outer side of the inner shell 11.

[0045] As Figures 5 to 7 shown, in some embodiments, an embedding groove 17 is provided in the inner shell 11, and the door body 21 is hinged in the embedding groove 17 through a rotating shaft. Thus, when the optical fiber connector pushes open the door body 21 and enters the installation channel, the door body 21 is placed in the embedding groove 17, and the end face of the protection protrusion 23 is flush with the notch end face of the embedding groove 17, that is, the door body 21 is received in the embedding groove 17, and then the optical fiber connector can continue to move forward, reducing unnecessary interference. Specifically, opposite installation holes are provided in the embedding groove 17, a rotating shaft is inserted into the installation holes, the door body 21 is rotatably connected to the rotating shaft, the elastic member 22 is a torsion spring, the torsion spring is sleeved on the rotating shaft, and placement grooves for placing the torsion spring are provided on both the door body 21 and the bottom of the embedding groove 17, so that the door body 21 can smoothly press the torsion spring when rotating, accumulating elastic potential energy. In the current embodiment, the placement groove at the bottom of the embedding groove 17 is formed by the depression of the bottom wall of the groove; the placement groove on the door body 21 is formed by the clamping protrusions 24 spaced on the door body 21, thus avoiding grooving on the door body 21 and avoiding affecting the strength of the door body 21. Due to the existence of the above-mentioned clamping protrusions 24, a hollow groove 25 is provided at the bottom of the placement groove, so that the above-mentioned clamping protrusions 24 can be embedded therein, avoiding protruding from the placement groove. It should be noted here that the limiting protrusion 3 is located on the inner wall of the inner shell 11.

[0046] As Figure 4 shown, in some embodiments, 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. Thus, 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. It should be noted here that the dividing line between the first shell part 111 and the second shell part 112 is not specifically limited. In the current 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 mutually clamped to form a complete inner shell 11, and the outer shell 12 is sleeved on the outside of the first shell part 111 and the second shell part 112, and can stably connect the first shell part 111 and the second shell part 112 together.

[0047] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
