Description

Technical Field

[0001] The utility model relates to the technical field of MT short ferrule dust caps, and relates to a novel MT short ferrule dust cap structure and an MT short ferrule. Background Art

[0002] In order to avoid the fiber core at the end face of the MT short ferrule being contaminated by dust, a dust cap is usually worn outside the MT short ferrule. However, at present, due to the short length dimension of the MT short ferrule, the dust cap will completely cover the surface of the MT short ferrule after being put on, resulting in limited operating space during the process of removing or putting on the dust cap of the MT short ferrule, and it is easy to break the optical fiber on the MT short ferrule, resulting in defective products; in addition, due to the large gap between the existing dust cap and the MT short ferrule, the dust cap on the MT short ferrule often falls off during transportation. Content of the Utility Model

[0003] Aiming at the above technical problems existing in the prior art, a novel MT short ferrule dust cap structure and an MT short ferrule are provided, which solve the problems that due to the limited operating space during the process of removing or putting on the dust cap of the MT short ferrule, it is easy to break the optical fiber on the MT short ferrule, resulting in defective products, and due to the large gap between the existing dust cap and the MT short ferrule, the dust cap on the MT short ferrule often falls off during transportation.

[0004] The purpose and effect of the utility model are achieved by the following specific technical means:

[0005] A novel MT short ferrule dust cap structure includes a dust cap main body;

[0006] On the one hand, the inside of the dust cap main body has a limiting groove for limiting the MT short ferrule, and soft sleeves integrally formed are arranged on both sides of the entrance end of the dust cap main body. The soft sleeves are used to sleeve the exposed corners of the MT short ferrule, and at least one notch is opened at the entrance end of the dust cap main body.

[0007] Optionally, a reserved space communicating with the limiting groove is provided inside the dust cap main body.

[0008] Optionally, reinforcing ribs are arranged on both sides of the dust cap main body.

[0009] On the other hand, a novel MT short ferrule includes the above novel MT short ferrule dust cap structure, an optical fiber and an MT short ferrule. The optical fiber is installed on the MT short ferrule, the MT short ferrule is inserted into the limiting groove, and the two soft sleeves respectively wrap the two exposed corners of the MT short ferrule.

[0010] Optionally, the length of the outer end of the MT short ferrule exposed is about one-fourth of the total length.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The novel MT short ferrule dust cap structure is conducive to stably wearing the dust cap body on the outside of the MT short ferrule under the joint action of the limiting groove and the two soft sleeves, effectively preventing the dust cap body from falling off the MT short ferrule during transportation. At this time, the inner wall of the limiting groove fits the outer wall of the MT short ferrule, which has a good dust and water proof effect on the inner end face of the MT short ferrule; after the dust cap body is worn, the reserved space will not be occupied by the MT short ferrule, so the inner end face of the MT short ferrule can be protected, and the problem of the optical fiber at the inner end face of the MT short ferrule being broken due to collision with foreign objects can be avoided; the notch increases the exposed part of the MT short ferrule, increases the operating space of the MT short ferrule when removing or wearing the dust cap body, avoids touching the optical fiber with hands, and effectively prevents the optical fiber from being broken; the operation is simple, and it is convenient for operators to wear or remove the dust cap body 1.

[0016] See also Figure 1-2 , the embodiments of the utility model are further described;

[0017] A novel MT short ferrule dust cap structure comprises a dust cap body 1, wherein the dust cap body 1 has a limiting groove 4 for limiting the position of the MT short ferrule 8, and the MT short ferrule 8 is closely fitted with the inner wall of the limiting groove 4 after being inserted into the limiting groove 4. The design of the limiting groove 4 can not only prevent dust and water from entering the dust cap body 1, but also avoid the undesirable condition of too much or too little dust cap body 1 after being worn on the MT short ferrule 8, that is, the length of the MT short ferrule 8 entering the dust cap body 1 can be effectively controlled. The reserved space 5 communicates with the groove 4, and both sides of the entrance end of the dust cap body 1 are provided with an integrally formed soft sleeve 6, the soft sleeve 6 is used to cover the exposed corners of the MT short ferrule 8, and can further limit the MT short ferrule 8, which is conducive to the MT short ferrule 8 being stably located in the dust cap body 1. At least one notch 2 is opened at the entrance end of the dust cap body 1, so that the exposed part of the MT short ferrule 8 is increased, and the operation space of the MT short ferrule 8 when removing or putting on the dust cap body 1 is increased, so as to avoid touching the optical fiber 7 with hands, and effectively prevent the optical fiber 7 from being broken.

[0018] In order to enhance the wrapping force of the dust cap body 1 , reinforcing ribs 3 are provided on both sides of the dust cap body 1 , so as to prevent the dust cap body 1 from falling off from the MT short ferrule 8 during transportation.

[0019] The utility model also provides a new type of MT short ferrule, including the new type of MT short ferrule dust cap structure, optical fiber 7 and MT short ferrule 8, optical fiber 7 is installed on MT short ferrule 8, MT short ferrule 8 is inserted into the limit groove 4, and two soft sleeves 6 respectively wrap the two exposed corners of MT short ferrule 8. The exposed length of the outer end of MT short ferrule 8 is about one-fourth of the total length, which is convenient for the operator to pinch the MT short ferrule 8 and take out the dust cap body 1.

[0020] Working principle: Before wearing the dust cap body 1, bend the two soft sleeves 6 outwards to facilitate the MT short ferrule 8 to enter the limiting groove 4. You can also cut the corners at the limiting groove 4 near the entrance end of the dust cap body 1 so that the MT short ferrule 8 can quickly and smoothly enter the limiting groove 4. When the inner wall of the limiting groove 4 presses against the inner end of the MT short ferrule 8, it means that the dust cap body 1 is well worn. Then, the two soft sleeves 6 are respectively put on the two exposed corners of the MT short ferrule 8. Under the joint action of the limiting groove 4 and the two soft sleeves 6, it is conducive to stably wearing the dust cap body 1 on the outside of the MT short ferrule 8. At this time, the inner wall of the limiting groove 4 fits the outer wall of the MT short ferrule 8, which has a good dustproof and waterproof effect on the inner end face of the MT short ferrule 8. Figure 2 As shown, after the dust cap body 1 is put on, the reserved space 5 will not be occupied by the MT short core 8, so the inner end surface of the MT short core 8 can be protected to avoid the problem that the optical fiber 7 at the inner end surface of the MT short core 8 is hit by foreign objects and thus broken.

[0021] If the dust cap body 1 needs to be removed from the MT short ferrule 8 , the removal can be completed by following the reverse steps of the above wearing steps. The operation is simple and convenient for operators to wear or remove the dust cap body 1 .
