Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber distribution frames, in particular to a distribution frame for an optical fiber splitter. Background Art

[0002] At present, there are two known structural forms of optical fiber distribution frame devices. The first is that there is no position for installing a splitter in the optical fiber distribution frame device. When in use, it must be used in conjunction with an independent splitter, which will inevitably occupy more space in the optical network unit cabinet; the second is that the optical splitter is arranged in the optical fiber distribution frame device and fixed in the optical fiber distribution frame device.

[0078] like Figures 1 to 4 As shown, the clamping assembly includes:

[0079] A first support base 411, the bottom of which is slidably connected to the outer wall of the second sliding block 15, and a third sliding groove 4111 is provided at the bottom of the first support base 411;

[0080] The second support base 412 has a bottom that is slidably connected to the outer wall of the second slider 15, one end of the second support base 412 is fixedly connected to the first support base 411 via a third spring 415 and a fourth spring 416, and a fifth sliding groove 4121 is provided at the bottom of the second support base 412;

[0082] One end of the second clamping block 414 is fixedly connected to the top surface of the second supporting base 412 .

[0083] In the embodiment of the utility model, the first clamp block 413 and the second clamp block 414 are both composed of a rectangular block and a triangular block fixedly welded at one end; the staff makes the optical fiber splitter contact with the first clamp block 413 and the second clamp block 414, and then separates the first support base 411 and the second support base 412 through the third spring 415 and the fourth spring 416, so that the bottom surface of the optical fiber splitter contacts with the top surface of the first support base 411 and the second support base 412, and the top surface of the optical fiber splitter is clamped together with the outer wall of the first clamp block 413 and the second clamp block 414, thereby ensuring that the optical fiber splitter is clamped between the first clamp block 413 and the second clamp block 414.

[0084] like Figures 1 to 4 As shown, the support assembly includes:

[0085] A fifth spring 421, one end of which is inserted into the third receiving groove 133 and fixedly connected to the square base 13;

[0086] The bottom surface of the support plate 422 is fixedly connected to the other end of the fifth spring 421 .

[0087] In the embodiment of the utility model, the support plate 422 provides a certain supporting force for the optical fiber splitter clamped between the first clamp block 413 and the second clamp block 414 through the fifth spring 421, thereby ensuring that the optical fiber splitter is clamped between the support plate 422, the first clamp block 413 and the second clamp block 414.

[0088] In a specific implementation manner: first, the staff makes the optical fiber splitter contact with the first clamp block 413 and the second clamp block 414, and then separates the first support base 411 and the second support base 412 through the third spring 415 and the fourth spring 416, so that the bottom surface of the optical fiber splitter contacts with the top surface of the first support base 411 and the second support base 412, and the top surface of the optical fiber splitter is clamped with the outer wall of the first clamp block 413 and the second clamp block 414, so as to ensure that the optical fiber splitter is clamped between the first clamp block 413 and the second clamp block 414, wherein the support plate 422 provides a certain supporting force for the optical fiber splitter through the fifth spring 421, so as to ensure that the optical fiber splitter is clamped between the support plate 422, the first clamp block 413 and the second clamp block 414;

[0089] Secondly, by winding the optical fiber in the fourth accommodating groove 211 of the two groups of semi-arc sliders 21, and providing a supporting force for the semi-arc slider 21 through the first spring 23, the optical fiber wound on the semi-arc slider 21 is always in a stable state, and the number of optical fiber winding turns is dynamically adjusted to ensure that the optical fiber will not break. The first arc block 22 welded on the semi-arc slider 21 can prevent the optical fiber from slipping. For the optical fiber wound on the semi-arc slider 21, the semi-arc block 34 provides a certain supporting force to the middle part of the wound optical fiber through the second spring 36. By cooperating with the two groups of semi-arc sliders 21, the number of optical fiber winding turns is dynamically adjusted, so that the wound optical fiber will not bend during the winding process.

[0090] Finally, the incoming optical fiber is connected to the fiber optic splitter through the line entry hole 111, and then multiple groups of crystal heads are installed on multiple groups of connection holes 112. Then one side of the box cover 12 and one end of the square tube 11 are fixed together by bolts, so that the fiber optic splitter is installed and fixed in the device.

[0091] The above is a preferred embodiment of the present invention.
