Description

Fiber adapter
Technical field
This creation system belongs to a kind of adapter, especially refer to a kind of fiber adapter, its assembly and disassembly are therefore favourable heavy industry easily, and can avoid using in the assembling process time-consuming and expensive assemble method such as ultrasonic welding, and then the enhancement packaging efficiency, improve the adapter productive rate.
Background technology
Fiber adapter two Connectorized fiber optic cablings of can plugging into, the entire length of extended fiber cable is beneficial to the configuration of fiber device by this.
The U.S. the 6th, 431, No. 762 the patent case has disclosed a fiber adapter, and it includes a shell, a sleeve pipe fixture, a sleeve pipe and certain hyte part.
This shell is that hollow has an inner space, is formed with transverse slat in the inner space, is formed with one first sleeve on transverse slat, and in addition, outer casing top surface is formed with a locating slot.This sleeve pipe fixture system is provided with in the enclosure, forms also one second sleeve on the sleeve pipe fixture, and first sleeve and second sleeve make up mutually sleeve pipe is fixed among first and second sleeve.In addition, the sleeve pipe fixture outside is formed with a laterally projecting locating lug, and this locating lug is resisted against on the transverse slat.This positioning component presents U-shaped and has two registration arm, registration arm penetrate locating slot and with the common block locating lug of transverse slat, by this sleeve pipe fixture is fixed in the shell.
Yet this fiber adapter has following many shortcomings.
1. at first, the structure that enclosure forms the transverse slat and first sleeve makes shell very complicated, can't reach desirable yield when making shell in the injection molding mode, so the shell cost of manufacture is high.
2. this U-shaped positioning component profile is tiny, and assembling needs to see through the accurate contraposition of human eye and avoids crooked, thereby expends built-up time.It is because the tiny cause of profile, in case promptly be difficult within the insertion locating slot withdraw from, when perishable sleeve pipe in assembling or use accidentally when fault or damage, assembler or consumer can't disassemble fiber adapter easily and carry out part replacement or reorganization, and if inadequate heavy industry easily causes the damage of casing appearance, therefore unfavorable heavy industry.Moreover this fiber adapter is fixed in needs extra another fastener that uses on the panel.
In addition, another kind of fiber adapter is also arranged, have forward and backward shell, two sleeve pipe fixture and sleeve pipes.Two sleeve pipe fixtures have a sleeve respectively, with behind two sleeve pipe fixture contrapositions and the fixed sleeving, forward and backward shell assembling are clamped two thimble assemblies, at last with the forward and backward shell of ultrasonic welding mode welding during assembling.Yet the ultrasonic welding must rely on additional power, expend energy cost, and process is also time-consuming, so cost is high equally.In addition, if use to go up sleeve pipe because of aging in the future, or cause and break when needing replacing, the forward and backward shell after the ultrasonic welding can't be disassembled, can't carry out heavy industry.Moreover the ultrasonic welding often has outward appearance crooked and produce the problem of burr.
Summary of the invention
This creator is because existing fiber adapter cost height, assemble time-consuming, problems such as unfavorable heavy industry, improve its not enough with lack, and then create a kind of fiber adapter.
