Description

Technical Field

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

[0002] A fiber optic adapter is an optical device used to achieve a detachable connection between two optical fibers. Its main function is to effectively couple the optical signal in the transmitting optical fiber to the receiving optical fiber to ensure the transmission continuity and minimal loss of the optical signal.

[0003] Existing integrated fiber optic adapters are usually composed of an outer shell, a card plug and a ceramic sleeve. For example, Chinese patent application number 201310690689.0 discloses an SC adapter with an improved structure. The outer shell and the card plug of this patent are both integrated structures. Although the outer shell of this structure is an integrated structure and no ultrasonic welding is required, since the card plug is an integrated structure, when the fiber optic plug is inserted, the hook arms on the card plug will be stretched and deformed, while the hook arms on the other side will be deformed close to each other, resulting in that when one end has been inserted into the fiber optic plug and the other end is inserted into the fiber optic plug, the hook arms are blocked by the fiber optic plug and are not easy to deform, making it difficult to insert the later inserted fiber optic plug, and no matter which side the fiber optic plug is inserted, the four hook arms will be deformed, resulting in a reduced service life. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated optical fiber adapter to solve the problems raised in the above background technology.

[0006] As a preferred solution of the utility model, notches are provided on the outer sides of the first card plug and the second card plug, and limiting blocks matching with the notches are provided at the four corners of the support plate.

[0007] As a preferred solution of the utility model, a fixing groove is provided on the outer side of the outer shell, and a metal spring is installed at the fixing groove.

[0008] As a preferred solution of the utility model, both ends of the outer shell are movably connected with dust caps, one end of the dust cap is provided with a plug hole, and both sides of the dust cap are provided with recessed parts.

[0009] As a preferred solution of the utility model, ceramic sleeves are installed inside the first sleeve and the second sleeve.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model divides the card plug into two parts, the first card plug and the second card plug, so that when the hook arm on one of the card plugs is deformed, the hook arm on the other card plug will not be deformed, thus avoiding the difficulty in inserting the optical fiber plug into the other end when one end of the outer shell is inserted into the optical fiber plug, making it convenient to use and reducing the number of deformations, thereby extending its service life. The positioning protrusion and the positioning groove are provided to limit the second card plug, thereby preventing the second card plug from offsetting with the support plate.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0018] See also Figures 1 to 5 The utility model provides a technical solution: an integrated optical fiber adapter, comprising an outer shell 1, a support plate 12 arranged inside the outer shell 1, and a second sleeve 6 arranged on one side of the support plate 12. The outer shell 1 is an integrated structure to ensure the firmness of the outer shell 1. The second card plug 8 and the first card plug 7 are sequentially installed inside the outer shell 1. The first card plug 7 and the second card plug 8 are both provided with hook arms for fixing the optical fiber plugs. The hook arms are prior art, so they are not described in detail. The second card plug 8 is provided with a through hole to facilitate the ceramic sleeve 5 to pass through, and the card plug is divided into two parts, the first card plug 7 and the second card plug 8, so that when the hook arm on one of the card plugs is deformed, the hook arm on the other card plug will not be deformed, thereby avoiding the deformation of the hook arm when one end of the outer shell 1 is inserted When inserting the optical fiber plug, it makes it more difficult to insert the other end into the optical fiber plug, which is convenient to use, reduces the number of deformation times, and prolongs its service life. A positioning groove 16 is provided on the inner side of the second card plug 8, and a positioning protrusion 4 that cooperates with the positioning groove 16 is provided on the side of the support plate 12 away from the second sleeve 6. The positioning protrusion 4 and the positioning groove 16 are used to limit the second card plug 8 to prevent the second card plug 8 from offsetting with the support plate 12, and ensure that the through hole on the second card plug 8 can be aligned with the second sleeve 6. A first sleeve 15 is provided on the first card plug 7, and elastic brackets 10 are provided on both sides of the first card plug 7. The inner side wall of the outer shell 1 is provided with a wedge block 9 that cooperates with the elastic bracket 10. The elastic bracket 10 cooperates with the wedge block 9 to fix the first card plug 7 inside the outer shell 1.

[0019] Among them, the outer sides of the first card plug 7 and the second card plug 8 are both provided with notches 18, and the four corners of the support plate 12 are provided with limit blocks 11 that match the notches 18. The limit blocks 11 are inserted into the notches 18, thereby limiting the second card plug 8 and the first card plug 7, making the installation of the first card plug 7 and the second sleeve 6 more stable, and also facilitating the alignment of the first sleeve 15 with the second sleeve 6.

[0020] A fixing groove 17 is provided on the outer side of the outer shell 1 , and a metal spring 3 is installed at the fixing groove 17 . The metal spring 3 is used to fix the outer shell 1 on the optical fiber box or other installation positions.

[0021] Among them, dust caps 2 are movably inserted at both ends of the outer shell 1. The dust cap 2 plays a covering role when the optical fiber adapter is not in use to prevent dust and other impurities from entering the outer shell 1, thereby keeping the optical fiber end face clean. A plug hole 14 is provided at one end of the dust cap 2. The plug hole 14 allows the dust cap 2 to be sleeved on the outside of the second sleeve 6 or the first sleeve 15. Recesses 13 are provided on both sides of the dust cap 2. The recesses 13 are used to cooperate with the hook arm to prevent the dust cap 2 from separating from the outer shell 1.

[0022] A ceramic sleeve 5 is installed inside the first sleeve 15 and the second sleeve 6 , and the ceramic sleeve 5 is used to enable the optical fiber end faces to be aligned quickly and accurately.

[0023] Specifically, during assembly, first insert the second card plug 8 into the outer shell 1, align the positioning groove 16 with the positioning protrusion 4, make the second card plug 8 close to the support plate 12, and then take the first card plug 7 and insert it. During the insertion process, the elastic bracket 10 is squeezed and contracted by the wedge block 9. When the first card plug 7 and the second card plug 8 are close, the elastic bracket 10 pops open and resets. The elastic bracket 10 is blocked by the wedge block 9 and cannot move, and the first card plug 7 is blocked by the second card plug 8 and cannot move. Then, the first card plug 7 is fixed, and finally the dust cap 2 is installed to complete the assembly.
