Description

Optical fiber adapter

Technical Field

The present invention relates to an adapter, and more particularly, to an optical fiber adapter into which an optical fiber connector is inserted.

Background

Referring to fig. 1 and 2, a fiber optic adapter 1 for a fiber optic connector with a Quad Small Form-factor (QSFP) interface includes a housing 11, two flanges 12 protruding from two sides of the housing 11, a partition wall 13 disposed in the housing 11, a mounting seat 14 disposed on one surface of the partition wall 13 and protruding from the partition wall 13, and a fixing seat 15 disposed on the other surface of the partition wall 13 and protruding from the partition wall 13 in an opposite direction. The mounting seat 14 defines a plurality of through holes 141. The fixing base 15 defines a plurality of through holes 151 respectively communicating with the through holes 141. The fixing base 15 includes a plurality of base walls 152 connected to each other in a group by two, and two clamping walls 153 disposed corresponding to the base walls 152. Each of the base walls 152 and the two clamping walls 153 surround a ring structure having three slots and define the through hole 151, and the optical fiber adapter 1 is used for inserting at least one set of corresponding optical fiber connectors and optically connecting the two optical fiber connectors of each set with each other through the through hole 141 and the through hole 151.

However, when the optical fiber adapter 1 is molded in a mold, the structure of each base wall 152 and the two clamping walls 153 surrounding the ring makes the optical fiber adapter 1 difficult to be demolded, so it is necessary to rely on forced demolding to remove the optical fiber adapter, and forced demolding will pull the clamping walls 153 outward until the optical fiber adapter is recovered after demolding, and the foregoing process makes the clamping walls 153 easy to deviate from the original position to cause errors, so there is room for improvement.

The utility model is described in detail below with reference to the following figures and examples:

referring to fig. 3, 4 and 5, a front-back direction a, a top-down direction B and a left-right direction C are first defined, wherein the front-back direction a is based on a direction of a user when plugging and unplugging the optical fiber connector, but the directions are not limited to the above-mentioned directions. The optical fiber adapter 2 comprises a housing 3, a partition wall 4 disposed in the housing 3, a mounting seat 5 disposed in the housing 3, and a fixing seat 6 disposed in the housing 3. The housing 3 surrounds and defines an inner space 31 extending in the front-rear direction a. The partition wall 4 is disposed on the inner surface of the housing 3 and located in the inner space 31, and divides the inner space 31 into two accommodating grooves 41 spaced along the front-rear direction a, and the partition wall 4 defines a plurality of through holes 42 extending along the front-rear direction a and communicating with the accommodating grooves 41. The mounting seat 5 and the fixing seat 6 are respectively disposed on two opposite sides of the partition wall 4 along the front-rear direction a, so as to be located in the accommodating groove 41. The mounting seat 5 defines a plurality of through holes 51 aligned with and communicating with the through holes 42. The fixing seat 6 includes a plurality of base walls 61 connected with each other in pairs, a plurality of clamping walls 62 disposed corresponding to the base walls 61, and a plurality of clamping walls 63 disposed corresponding to the base walls 61 and the clamping walls 62. Each base wall 61, two clamping walls 62 and one clamping wall 63 enclose an annular structure with four gaps and define a through hole 64 aligned with and communicating with one of the through holes 42 of the partition wall 4. The clamping wall 63 is located between the two corresponding clamping walls 62. Each group of base walls 61 of the fixing base 6 is spaced apart from each other in the up-down direction B, and different groups of base walls 61 are spaced apart from each other in the left-right direction C.

In the first embodiment, a ring structure design of three-piece four gaps is adopted in which two clamping walls 62 are matched with one clamping wall 63, and the gaps can make the clamping walls 62 and the clamping walls 63 have large elastic margins, so that the force required for demolding can be reduced, the optical fiber adapter 2 is easy to demold, and forced demolding for forcibly and rigidly pulling an object outwards is not required, so that the clamping walls 62 and the clamping walls 63 are not deformed after demolding.

Referring to fig. 6, 7 and 8, a second embodiment of the fiber optic adapter 2 of the present invention is shown, which is substantially the same as the first embodiment except that: the housing 3 includes a main wall portion 32 surrounding the inner space 31, and two guide rail portions 33 protruding from one side of the main wall portion 32 in the left-right direction C. The rail portions 33 are spaced apart in the up-down direction B, and each rail portion 33 extends in the front-rear direction a. The main wall portion 32 is provided with two guide grooves 321 spaced apart from each other in the up-down direction B on the other side in the left-right direction C, and each guide groove 321 extends in the front-back direction a. In the second embodiment, flanges (flanges) are not provided on both sides of the main wall portion 32, but the guide rail portion 33 is engaged with the guide grooves 321 of the other fiber optic adapters 2 as shown in fig. 8, so as to connect the plurality of fiber optic adapters 2 in parallel in the left-right direction C, and the main wall portions 32 of the fiber optic adapters 2 can be closely arranged by closing each other without occupying additional space in the left-right direction C when being mounted in the guide grooves 321 through the guide rail portion 33, which can be applied to a narrow space. Referring to fig. 9, 10 and 11, it should be particularly noted that, when a structure that needs to be connected by a flange is required, as shown in fig. 9 or 10, the fiber adapter 2 may also be provided with a flange 35 on one side and the guide rail portion 33 or the guide groove 321 on the other side, and these different types of fiber adapters 2 can be connected with each other through the guide rail portion 33 and the guide groove 321, so as to meet different installation requirements and improve the versatility.

Referring to fig. 12 and 13, a third embodiment of the fiber optic adapter 2 of the present invention is generally the same as the second embodiment except that: the housing 3 further includes four locking portions 34 protruding from two sides of the main wall portion 32 in a group of two by two along the up-down direction B, the two locking portions 34 located on the same side of the main wall portion 32 are spaced from each other along the left-right direction C, and each locking portion 34 extends along the front-back direction a. The locking portion 34 can push the groove wall outwards when the main wall portion 32 is placed in the groove-shaped space, so as to achieve the effect of auxiliary fixation, and thus the fixation can be completed without depending on a flange (flange), thereby achieving the effect of compact configuration. Referring to fig. 14, the third embodiment can also be implemented with fewer through holes 51 (hidden from view and not shown) and fewer through holes 64 (hidden from view and not shown) as shown in fig. 14, so as to meet different connection quantity requirements.

In summary, the present invention does not require forced demolding, and can ensure that the clamping wall 62 and the clamping wall 63 do not shift, so as to avoid the normal and non-offset aperture of the through hole 64.

The above description is only for the preferred embodiment of the present invention, and it is not intended to limit the scope of the present invention, and any person skilled in the art can make further modifications and variations without departing from the spirit and scope of the present invention, therefore, the scope of the present invention should be determined by the claims of the present application.
