Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, and in particular to a highly compatible ROSA adapter housing. Background Technology

[0002] There are two common types of high-compatibility ROSA adapter housings on the market. The first type can be adapted to the SC interface, and the second type can be adapted to the FC / ST interface. However, the only difference between the two types is that the outer diameter of the limiting ring on the high-compatibility ROSA adapter housing of the second type is 0.7mm smaller than that of the first type. The difference between the two types of high-compatibility ROSA adapter housings is minimal. It would require the cost of two sets of molds to produce the two types of high-compatibility ROSA adapter housings separately. Utility Model Content

[0003] The purpose of this invention is to provide a highly compatible ROSA adapter housing to solve the aforementioned problems in the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A highly compatible ROSA adapter housing includes a cylindrical base and an end, and an intermediate ring coaxially disposed between the base and the end. One end of the intermediate ring engages with the end, and the other end of the intermediate ring has a limiting ring with an outer diameter matching that of a limiting ring of a second type of highly compatible ROSA adapter housing. The end of the limiting ring is cut with a slot, and one end of the base has a corresponding insertion ring for engaging with the intermediate ring. The outer circumference of the insertion ring has multiple protrusions, and the inner wall of the slot has multiple grooves corresponding to the protrusions. The height of the protrusions and the depth of the grooves are 0.35 mm.

[0005] The advantages of this invention are: by setting grooves and protrusions, the outer diameter of the limiting ring can be controlled to adapt to different interfaces; only one set of molds is needed to complete the manufacturing of two highly compatible ROSA adapter shells, saving costs.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a concave ring is provided at one end of the intermediate ring, and a convex ring is provided on the inner wall of the end corresponding to the concave ring, so that the intermediate ring and the end are engaged by the concave ring and the convex ring.

[0008] The further beneficial effect of adopting the above is that the concave ring and the convex ring are interlocked, making assembly convenient.

[0009] Furthermore, the annular edges of the insert ring, slot, concave ring, and convex ring are all rounded.

[0010] The further beneficial effect of adopting the above is that the friction of the edges is small, making insertion easier. Attached Figure Description

[0013] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0014] Example 1 like Figures 1 to 5 As shown, a highly compatible ROSA adapter housing includes a cylindrical base 1 and an end 3, and an intermediate ring 2 coaxially disposed between the base 1 and the end 3. One end of the intermediate ring 2 is engaged with the end 3, and the other end of the intermediate ring 2 is provided with a limiting ring 21 whose outer diameter is the same as the outer diameter of the limiting ring of the second type of highly compatible ROSA adapter housing. The end of the limiting ring 21 is cut open to provide a slot 23. One end of the base 1 is provided with an insert ring 11 corresponding to the slot 23 so that the base 1 is engaged with the intermediate ring 2. The outer circumference of the insert ring 11 is provided with multiple protrusions 12, and the inner wall of the slot 23 is provided with multiple grooves 24 corresponding to the multiple protrusions 12. The height of the protrusions 12 and the depth of the grooves 24 are 0.35mm.

[0015] During assembly, first connect the intermediate ring 2 to the end 3, then insert the base 1 into the intermediate ring 2, so that the insertion ring 11 is inserted into the slot 23, and the protrusion 12 slides into the slide groove 24. Once inserted into place, the assembly of the second type of high-compatibility ROSA adapter shell is complete, which can be adapted to FC / ST interfaces (such as...). Figure 2Based on the above, by twisting the base 1 and the limiting ring 21 relative to each other, the protrusion 12 rotates out of the slide groove 24. The protrusion 12 pushes the limiting ring 21 outward along the circumferential direction, causing a slight deformation of the limiting ring 21 and an expansion of its outer diameter. This completes the assembly of the first type of high-compatibility ROSA adapter shell, which can be adapted to SC interfaces (such as...). Figure 3 By setting the groove 24 and the protrusion 12, the outer diameter of the limiting ring 21 is controlled to adapt to different interfaces; only one set of molds is needed to complete the manufacturing of two ROSA adapter shells, saving costs.

[0016] In practice, after the base 1, end 3 and intermediate ring 2 are installed and adjusted in place, and the shell of a certain type of ROSA adapter is completed, the base 1, intermediate ring 2 and end 3 are welded along the outer wall edge in sequence to prevent them from loosening or falling off.

[0017] Example 2 This embodiment is a further improvement on embodiment 1, as detailed below: The slot 23 has a Z-shaped cross-section, and the insertion ring 11 also has a Z-shaped cross-section. This ensures that the base 1 and the intermediate ring 2 can be inserted into place and locked in place, preventing them from easily falling off.

[0018] One end of the intermediate ring 2 is fitted with a concave ring 22, and the inner wall of the end 3 is fitted with a convex ring 31 corresponding to the concave ring 22, so that the intermediate ring 2 and the end 3 are engaged by the concave ring 22 and the convex ring 31. The engagement of the concave ring 22 and the convex ring 31 makes assembly convenient.

[0019] The annular edges of the insertion ring 11, slot 23, concave ring 22, and convex ring 31 are all rounded. The edges have low friction, making insertion easier.

[0020] In practice, the intermediate ring 2 is integrally formed and made of stainless steel. The expansion of the stainless steel limiting ring 21 is irreversible, and after the limiting ring 21 expands, the inner wall of the Z-shaped groove will clamp the protrusion 12 to prevent the protrusion 12 from falling back into the slide groove 24.

[0021] Example 3 This embodiment is a further improvement on embodiment 1, as detailed below: The outer walls of the base 1 and the limiting ring 21 are respectively provided with a first reference line 13 and a second reference line 25. Align the first reference line 13 with the second reference line 25 and insert the base 1 into the intermediate ring 2, so that the guide protrusion 12 slides into the corresponding groove 24.

[0022] Protrusion 12 is a hemispherical protrusion, and groove 24 is a hemispherical groove. The hemispherical surface is smooth, resulting in low sliding friction.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
