Abstract
A dustproof cap of a plug-in strip type splitter with a waterproof function comprises a sleeve joint part and a waterproof part which are integrally connected, wherein the sleeve joint part is a cylindrical body, and a blind hole is formed in the sleeve joint part; the waterproof portion is arranged on one side of the sleeving portion and is a conical solid body. Compared with the prior art, the dustproof cap of the plug-in splitter with the waterproof function of the utility model has the advantages that the sleeve of each adapter of the plug-in splitter is sleeved with the dustproof cap, so that the sleeve is tightly wrapped by the sleeved part of the dustproof cap, on one hand, the waterproof cap is covered to ensure more accurate water soaking experimental result, the quality is ensured, and the user can feel more relieved when using the product; on the other hand, the utility model can prevent moisture and dust when not used for storage in the later period.
Description
Technical Field
The utility model relates to an optical divider technical field specifically indicates a from inserted sheet formula branching unit dust cap of taking waterproof function.
Background
An optical splitter, known as a planar waveguide optical splitter (PLCSplitter), is an integrated waveguide optical power distribution device based on a quartz substrate, has the characteristics of small volume, wide working wavelength range, high reliability, good splitting uniformity and the like, and is particularly suitable for connecting local terminals and terminal equipment in passive optical networks (EPON, BPON, GPON and the like) and realizing splitting of optical signals. There are two types, 1 xn and 2 xn splitters that either evenly split the optical signal from a single or double inlet into multiple outlets or work in reverse to merge multiple optical signals into a single or double fiber.
At present, various experimental performance requirements of operators on optical splitters are higher and higher, for example, the requirements of 'splitter technical specification' collected by china mobile in 2015 are as follows: branching unit will soak under the normal atmospheric temperature condition, and the immersion water is soaked for 168 hours, and the insertion loss variation is less than or equal to 0.5dB, but most inserted sheet formula branching unit dust cap on the existing market do not have the function of blocking water, and the inside can permeate a lot of water when soaking, leads to the water logging experiment of branching unit inaccurate. Influence the final experimental result judgment.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is not enough to above-mentioned prior art, and provide a from inserted sheet formula branching unit dust cap of taking waterproof function.
In order to solve the technical problem, the utility model discloses a technical scheme is:
a dustproof cap of a plug-in strip type splitter with a waterproof function comprises a sleeve joint part and a waterproof part which are integrally connected, wherein the sleeve joint part is a cylindrical body, and a blind hole is formed in the sleeve joint part; the waterproof portion is arranged on one side of the sleeving portion and is a conical solid body.
Furthermore, the diameter of the excircle of the sleeving part is 5.6mm, and the length of the excircle of the sleeving part is 7 mm; the diameter of the blind hole is 4.8mm, and the length of the blind hole is 6.5 mm.
Further, the length of the waterproof part is 13mm, and the taper angle is 20 degrees.
Furthermore, the material of the sleeve joint part and the material of the waterproof part are both rubber.
Compared with the prior art, the dustproof cap of the plug-in splitter with the waterproof function of the utility model has the advantages that the sleeve of each adapter of the plug-in splitter is sleeved with the dustproof cap, so that the sleeve is tightly wrapped by the sleeved part of the dustproof cap, on one hand, the waterproof cap is covered to ensure more accurate water soaking experimental result, the quality is ensured, and the user can feel more relieved when using the product; on the other hand, the utility model can prevent moisture and dust when not used for storage in the later period.
