Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0035] The utility model proposes a fiber optic adapter 100, which is installed in an assembly hole 210 of an adapter panel 200. The fiber optic adapter 100 includes a shell 10 and an anti-loosening buckle 20. The anti-loosening buckle 20 is connected to the outer wall surface of the shell 10 and is clamped with the assembly hole 210. The anti-loosening buckle 20 is provided with a first anti-loosening arm 201, a second anti-loosening arm 202 and a third anti-loosening arm 203. The first anti-loosening arm 201 is against the transverse hole wall of the assembly hole 210, the second anti-loosening arm 202 is against the longitudinal hole wall of the assembly hole 210, and the third anti-loosening arm 203 is against the end face of the assembly hole 210.

[0036] The housing 10 is generally made of plastic material, specifically polyethylene (PE), polypropylene (PP), polycarbonate (PC), etc., which has good mechanical properties, heat resistance and corrosion resistance. Generally, the housing 10 has a first receiving groove and a second receiving groove for the optical fiber end to extend into at opposite ends, and the housing 10 is also provided with an optical fiber channel connected to the first receiving groove and the second receiving groove.

[0037] The anti-loosening buckle 20 can be made of the same material as the housing 10, and the two can be connected in one piece or by means of clamping, hot melting, etc. In some embodiments of the utility model, the anti-loosening buckle 20 is made of metal. Specifically, it can be made of aluminum alloy, steel, etc., so that each anti-loosening arm has good elasticity and high strength. The specific connection method and specific material of the anti-loosening buckle 20 and the housing 10 are set according to the specific situation and are not limited here.

[0038] The first anti-loosening arm 201 and the second anti-loosening arm 202 are both elastic. When the optical fiber adapter 100 is not installed in the assembly hole 210, the first anti-loosening arm 201 and the second anti-loosening arm 202 are naturally tilted, and the outer dimensions are slightly larger than the dimensions of the assembly hole 210. The first anti-loosening arm 201 and the second anti-loosening arm 202 have a certain inclination. The first anti-loosening arm 201 and the second anti-loosening arm 202 are inclined in the direction away from the adapter panel 200 and away from the housing 10, so that the optical fiber adapter 100 is conveniently inserted into the assembly hole 210. Since the clamping structure for clamping the optical fiber adapter 100 in the assembly hole 210 is generally located on the inner side of the assembly hole 210, the third anti-loosening arm 203 is correspondingly arranged on the outer side of the assembly hole 210, so that the third anti-loosening arm 203 and the clamping structure are clamped on opposite sides of the adapter panel 200.

[0039] Through the above scheme, the utility model can secure the optical fiber adapter 100 to the adapter panel 200 in three perpendicular directions, namely, the horizontal direction, the vertical direction, and the insertion direction of the optical fiber adapter 100, through the first anti-loosening arm 201, the second anti-loosening arm 202, and the third anti-loosening arm 203, to ensure that the optical fiber adapter 100 will not shake in all directions, or the shaking amplitude is extremely small, thereby ensuring the stability of the signal transmission of the optical communication.

[0040] In some embodiments of the utility model, the anti-loosening buckle 20 includes a main body 21 and two assembly arms 22, the two assembly arms 22 are connected to opposite sides of the main body 21 in the circumferential direction of the assembly hole 210, the main body 21 is installed on a side wall in the transverse direction of the housing 10, and the two assembly arms 22 are respectively installed on a side wall in the longitudinal direction of the housing 10; the main body 21 is formed with a first anti-loosening arm 201, and the assembly arm 22 is formed with a second anti-loosening arm 202. With such a configuration, the anti-loosening buckle 20 is easy to install, and when each anti-loosening arm is broken or fatigued due to stress and the elastic force becomes smaller, the anti-loosening buckle 20 can be replaced, and the replacement cost is low.

[0041] Furthermore, in some embodiments of the present invention, the main body 21 is provided with a snap-fitting arm 211, one end of the snap-fitting arm 211 is connected to the main body 21, and the other end of the snap-fitting arm 211 is tilted in a direction away from the housing 10, so that during the installation of the optical fiber adapter 100, the snap-fitting arm 211 is pressed by the wall of the assembly hole 210 and shrinks. When the optical fiber adapter 100 is assembled in place, the snap-fitting arm 211 pops up and respectively presses against the opposite end surfaces of the assembly hole 210 with the third anti-loosening arm 203, effectively limiting the loosening of the optical fiber adapter 100 in the direction in which the assembly hole 210 is opened, and the assembly is convenient and the anti-loosening effect is good.

[0042] Considering that the clamping arm 211 will be pressed by the wall of the assembly hole 210 and shrink during the process of being inserted into the assembly hole 210, in some embodiments of the utility model, the main body 21 is formed with an avoidance hole 222, one end of the clamping arm 211 is connected to the hole wall of the avoidance hole 222 away from the first anti-loosening arm 201, and the other end of the clamping arm 211 is pressed against the end surface of the assembly hole 210. In this way, the clamping arm 211 can shrink in the avoidance hole 222, which is more compact. On the other hand, the material and weight of the anti-loosening buckle 20 can be reduced, saving costs.

[0043] Furthermore, in some embodiments of the present invention, the width of one end of the clamping arm 211 connected to the hole wall of the avoidance hole 222 is smaller than the width of the end face of the clamping arm 211 against the mounting hole 210. In this way, the width of the end face of the clamping arm 211 against the mounting hole 210 is larger, and the clamping arm 211 is stably supported on the adapter panel 200 in the vertical direction, which can further prevent the optical fiber adapter from tipping forward or backward, and has better stability.

[0044] In some embodiments of the present invention, the first anti-loosening arm 201 and the third anti-loosening arm 203 are formed on a side of the main body 21 facing away from the housing 10 .

[0045] In other embodiments of the present invention, one end of the main body 21 in the direction of the assembly hole 210 is bent to form the first anti-loosening arm 201. Further, in some other embodiments of the present invention, the third anti-loosening arm 203 is bent and connected to the free end of the first anti-loosening arm 201. This is not only convenient for processing, but also has little effect on the thickness of the main body, and the main body 21 can be made thinner, which is conducive to further improving the compactness of the optical fiber adapter 100.

[0046] In some embodiments of the utility model, the surface of the housing 10 is provided with a first assembly groove 101 and two second assembly grooves 102 that are connected to each other. The two second assembly grooves 102 are respectively located on two sides adjacent to the first assembly groove 101 and are arranged opposite to each other. The main body 21 is assembled in the first assembly groove 101, and the assembly arm 22 is assembled in the corresponding second assembly groove 102. In this way, the main body 21 and the assembly arm 22 are respectively installed in the corresponding grooves, and the surface consistency of the optical fiber adapter 100 is good. In addition, the two second assembly grooves 102 can form a horizontal limit for the anti-loosening buckle 20, and the first assembly groove 101 can form a longitudinal limit for the main body 21. In this way, there is no need for glue or other connection structures between the anti-loosening buckle 20 and the housing 10, and the assembly and disassembly are convenient and the connection is reliable.

[0047] Furthermore, in order to ensure that the connection stability of the two opposite sides of the optical fiber adapter is consistent, in some embodiments of the present invention, two anti-loosening buckles 20 are provided, and the two anti-loosening buckles 20 are respectively installed on the opposite sides of the housing 10. In this way, the assembly stability of the optical fiber adapter 100 and the assembly hole 210 can be higher.

[0048] The utility model further provides an optical transmission device 1000, which includes an adapter panel 200 and the above-mentioned optical fiber adapter 100, wherein the adapter panel 200 is provided with an assembly hole 210, and the optical fiber adapter 100 is installed in the assembly hole 210. Since the optical transmission device 1000 adopts all the solutions in all the above-mentioned embodiments, it has at least all the technical effects brought by the technical solutions in all the above-mentioned embodiments, which will not be described one by one here.

[0049] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
