Abstract
The utility model discloses a kind of duplex LC attenuators, for symmetrical structure, including two LC connectors, two LC adaptable interfaces, front frame set and after-frame set, the front frame set and after-frame cover to form the ducted body that two front and backs penetrate through, it is respectively provided with a porcelain bushing in two ducted bodies, lock pin external member is equipped in the porcelain bushing, is equipped with optical fiber in the lock pin external member, optical fiber one connects LC connector, and other end connects LC adaptable interface.Troublesome wiring is saved in the cooperation that existing long cable and adapter can be substituted using this twin structure, simplifies space；Different losses concurrently or separately can be realized to reception or transmitting signal end, reach different transmission purposes by the type of change optical fiber；The structure for pressing handle may be implemented fast insert-pull movement, greatly reduce the time of installation or removal.
Description
Technical field
The utility model relates to optical communications to connect equipment, more particularly, to a kind of duplex LC attenuator.
Background technique
Now generally counted at present by multiple simply connected LC connectors when the interface between equipment is duplex LC type
According to transmission (for receiving data, one end is for sending data for one end), this meeting between equipment so that need to stay to transmission data wire
There are enough wirings or winding space, is at the same time protection equipment because being used for a long time the overall volume in a disguised form increased, occupies empty
Between increase meeting so that equipment design and optimization space reduction.
When wire jumper is damaged, at present there are two types of solution, one is handling wire jumper, but this needs the equipment producer
Or user possesses the ability of processing wire jumper, and equipment is probably stopped using due to replacement for a long time；Another kind is more
The time that stops breaking of the wire jumper renewed, equipment is short, but in order to give replacement line storage space, enterprise can tail off using space.
Summary of the invention
The technical purpose of the utility model is the switching processing between the current equipment of optimization, replace two wire jumpers be adapted to
Device saves more spaces for equipment, and meets different degrees of attenuation requirement.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of duplex LC attenuator, is symmetrical structure, including two LC connectors, two LC adaptable interfaces, front frame set and
After-frame set, the front frame set and after-frame cover to form the ducted body that two front and backs penetrate through, and a pottery is respectively provided in two ducted bodies
Porcelain bushing shell is equipped with lock pin external member in the porcelain bushing, is equipped with optical fiber in the lock pin external member, and optical fiber one connects LC connector,
Other end connects LC adaptable interface.
Further, described two LC connectors and two LC adaptable interfaces are equipped with dustproof cover.
Further, the lock pin external member includes two ceramic insertion cores and a metal external member.
Further, duplex LC attenuator after-frame set top is equipped with pressing handle.
Further, the optical fiber can choose and replace.
Further, the front frame set and after-frame set use plastic material.
The beneficial effects of the present invention are: using twin design structure, matching for existing long cable and adapter can be substituted
It closes, saves troublesome wiring, simplify space；It can be by the type of change optical fiber, concurrently or separately to reception or transmitting signal
Different losses is realized at end, reaches different transmission purposes；Fast insert-pull movement may be implemented, greatly in the structure for pressing handle
The time for reducing installation or removal.
Detailed description of the invention
Fig. 1 is the 3 dimensional drawing of the present embodiment.
Fig. 2 is the sectional front view of the utility model.
Fig. 3 is that the present embodiment structure is to overlook semi-cutaway.
In figure: 1 is front frame set；2 be front end dustproof cover；3 be lock pin external member；4 be after-frame set；5 be rear end dustproof cover；6 are
Porcelain bushing；7 be optical fiber.
Specific embodiment
In order to keep technological means of the utility model clear, it is practical new that this is further described with reference to the accompanying drawing
Type.
As shown in Figure 1-3, the structure in the duplex LC attenuator of the utility model is symmetrical structure, including two duplex LC
Attenuator front frame covers 1, two duplex LC attenuator after-frame and covers 4, the two rear end dustproof cover 5, two of front end dustproof cover 2, two potteries
6, two lock pin external members 3 of insulator cylinder and two optical fiber 7, as shown in Fig. 2, optical fiber 7 is penetrated by mode appropriate slotting when implementation
In core retainer plate part 3, lock pin external member crimps in advance, including two ceramic insertion cores and a metal external member are ground after relevant treatment
Former and later two end faces of assembled lock pin are ground, reach the effect of requirement, then sub-assembly is inserted in porcelain bushing 6.
Then as shown in figure 3, the ceramic jacket pipe end that two are combined is inserted into respectively in duplex LC attenuator after-frame set 4, and
Two duplex LC attenuator front frame sets 1 are inserted in duplex LC attenuator after-frame set 4, two front end dustproof covers 2 are finally installed
With two rear end dustproof covers 5.
In use, removing two front end dustproof covers 2 and two rear end dustproof covers 5, the insertion of duplex LC attenuator front end is set
In standby duplex adapter, equipment LC connector wire jumper is inserted into duplex LC attenuator rear end.When dismounting, after pressing duplex LC attenuator
The handle of frame set 4, duplex LC attenuator is extracted from adaptor interface, then the wire jumper of duplex LC attenuator rear end is pulled out,
Finally two duplex LC attenuator front frame sets 1 are inserted in duplex LC attenuator after-frame set 4, then install two front end dustproof covers
2 and two rear end dustproof covers 5.By the selection and replacement to optical fiber 7, different data transmission requirements can satisfy.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
