Abstract
An optical fiber adapter is provided with two symmetrical bases and two symmetrical fixing fasteners. A ceramic core-sleeve is inserted into the two symmetrical fixing fasteners, the two symmetrical fixing fasteners are tightly combined so as to fix the ceramic core-sleeve and are respectively fastened into the two symmetrical bases, and the two symmetrical bases are tightly combined so as to fix the two symmetrical fixing fasteners. The optical fiber adapter is low in insertion loss, high in reflection loss, fine in repeated plugging and unplugging property, stable in environment and fine in mechanical property, and can be applied to through connection among different types of insert cores of telecommunication networks, testing instruments and meters, local area networks (LAN), fiber to the home (FTTH), high-quality video transmission, optical fiber sensing, community antenna television (CATV) and the like.
Description
Technical field
The utility model relates to a kind of fiber adapter, refers in particular to a kind of fiber adapter that continues, is coupled that is used between the fiber active linker.
Background technology
In optical fiber telecommunications system, for the needs of realizing connecting flexibly between different equipment and the system, a kind of device that can flexibly connect between optical fiber and optical fiber must be arranged, light signal can be transmitted by required passage, can realize that the device of this function just is adapter.Fiber adapter is exactly the accurate butt joint of two end faces of optical fiber, the luminous energy that launching fiber is exported can be coupled to greatest extent to receive in the optical fiber and go, and make because it gets involved optical link the influence that system the causes basic demand that to reduce to minimum be fiber adapter.To a certain extent, fiber adapter has also influenced reliability and every performance of optical transmission system.Fiber adapter is the maximum De Guang of a use amount No source device in the fibre system.To the requirement of fiber adapter mainly be insert that loss is little, reflection loss is high, repeat that plug property is good, ambient stable and good mechanical property etc.Because fiber adapter also is a kind of loss product, so also require it cheap.Its typical case use comprise communication, Local Area Network, Fiber to the home (FTTH), high-quality video transmission, Fibre Optical Sensor, testing meter and instrument, CATV etc.
Chinese patent once disclosed a kind of " fiber adapter " (China, publication number CN2938150, open day on August 22nd, 2007), the housing that comprises the disjunctor design, be provided with upper inner-liner and bottom inner container in the housing, on, bottom inner container is made up of right cylinder that has through hole and the locator card that is located at the right cylinder both sides, the right cylinder disjunctor of upper inner-liner is located at enclosure interior, the spacer disjunctor of upper inner-liner is located on the bottom inner container, bottom inner container is plugged in the housing through joining slotting draw-in groove and rib mutually, structure after the improvement is simpler, use convenient, make manufacturing be more prone to after removing the split type ultrasonic welding process that necessarily requires, the housing of disjunctor design simultaneously crack and burr can not occur, profile is more attractive in appearance, quality is more reliable, excellent in cushion effect, avoid the phenomenon of split type housing frangibility, also can be designed to a plurality of parallel as required.It is a kind of conjoined structure.
Summary of the invention
The purpose of this utility model is to provide a kind of fiber adapter, and it is a split-type structural, inserts that loss is little, reflection loss is high, repeats that plug property is good, ambient stable and good mechanical property.
For achieving the above object, the solution that the utility model is taked is: a kind of fiber adapter, it has the pedestal of two symmetries and the clip of two symmetries, ceramic core-sleeve inserts in the clip of two symmetries, the clip of two symmetries is combined closely ceramic core-sleeve is fixed, the clip of two symmetries snaps in respectively in the pedestal of two symmetries, and the pedestal of two symmetries is combined closely the clip of two symmetries is fixed.
This fiber adapter is a split-type structural, insert that loss is little, reflection loss is high, repeat that plug property is good, ambient stable and good mechanical property, interchangeability≤0.2dB, typical case connecting loss≤0.3dB, typical case reflection loss 〉=40dB can be applicable to telecommunications network, testing meter and instrument, Local Area Network, the switching between different types lock pins such as Fiber to the home (FTTH), high-quality video transmission, Fibre Optical Sensor, CATV.

Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1-Fig. 7, a kind of fiber adapter, it has the pedestal 1 of two symmetries and the clip 2 of two symmetries, ceramic core-sleeve 3 inserts in the clip 2 of two symmetries, the clip 2 of two symmetries is combined closely ceramic core-sleeve 3 is fixing, the clip 2 of two symmetries snaps in respectively in the pedestal 1 of two symmetries, and the pedestal 1 of two symmetries is combined closely the clip 2 of two symmetries is fixing.
Referring to Fig. 1-Fig. 7, when not using, pedestal 1 port of described two symmetries covers with dust cap 4, prevents that dust from entering in the adapter.
Referring to Fig. 1-Fig. 7, the pedestal 1 of described two symmetries, one of them or two clamp shell fragment 5 in its surperficial groove, be convenient to adapter and install.
