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.
This creation fundamental purpose system provides a kind of optical fiber type orchestration, and 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 promotes packaging efficiency, improves the adapter productive rate.
For reaching above-mentioned purpose, be to make aforementioned fiber adapter include:
One shell runs through before and after on it and is formed with an accommodation space, two relative madial walls of accommodation space respectively laterally projection one stop block is arranged, locate to be formed with respectively a locating slot that is connected with accommodation space at outer casing top surface by both sides;
One anterior cannula fixture is to be arranged in the accommodation space and to have a sleeve and a fixed head, fixed head be formed at sleeve to inner and against stop block;
One rear sleeve fixture is to be arranged in the accommodation space and to have a sleeve and a fixed head, fixed head be formed at sleeve to inner and against stop block;
One sleeve pipe is to be arranged in the sleeve of anterior cannula fixture and rear sleeve fixture; And
One removable keeper, system is arranged on the shell with removably, and have a transverse slat, two side wings and two stop tab, this transverse slat setting and exposing on the outer casing top surface, wing plates on two sides is extended downwards from the transverse slat two ends respectively and is provided with and exposes on the shell both sides respectively, two stop tab are formed at the rear end of side wing respectively and are inserted in the locating slot respectively, two stop tab make two fixed heads be located between stop tab and the stop block against the fixed head of anterior cannula fixture and rear sleeve fixture.
By above-mentioned technological means, fiber adapter is unexpected to disintegrate the fixed head that stop block in the shell and the stop tab on the removable keeper clamp anterior cannula fixation kit and rear sleeve fixation kit jointly to avoid, the transverse slat of removable keeper and side wing are large-area tabular and expose to outside the shell in addition, when inner sleeve splits or damages, can point or instrument is stirred side wing, and then the fast removable keeper of quick-detach is in order to the heavy industry of fiber adapter.

Be formed with an engagement groove on aforementioned each first joint portion, each second joint portion is the combined block of a coupling engagement groove, and the engagement groove of anterior cannula fixture and combined block combine with the combined block and the engagement groove of rear sleeve fixture respectively.
Projection forward is formed with the flexible button pawl of two tools on the fixed head of aforementioned anterior cannula fixture, and projection backwards is formed with the flexible button pawl of two tools on the fixed head of this rear sleeve fixture.
Be formed with a upper groove on the aforementioned outer casing top surface to hold the transverse slat of removable keeper.
Be formed with a side groove that is communicated with upper groove and corresponding locating slot on the aforementioned shell both sides respectively so that hold corresponding side wing.
Be formed with at least one buckling parts in each side groove of aforementioned shell, be formed with a button hole on each side wing of removable keeper respectively to fasten the buckling parts of corresponding side groove.
Laterally outside respectively projection is formed with a holding block on the both sides of aforementioned shell, is formed with the drawing piece of a relative holding block on each side wing of removable keeper respectively.
Aforementioned anterior cannula fixture and rear sleeve fixture have identical appearance.
Aforementioned removable keeper is a metal material.
Aforementioned sleeve pipe is a ceramic material.
Aforementioned fiber adapter is coincident with the specification of SC fiber adapter.
