Description
Technical field
This utility model relates to the joints of optical fibre, the novel LC adapter of a kind of high stability overcoming angular deviation.
Background technology
The joints of optical fibre, it is between optical fiber with optical fiber, to carry out the device that detachable (movable) is connected, it gets up the two of optical fiber end face precision docking, so that the light energy of launching fiber output can be coupled to receive in optical fiber to greatest extent, and making impact system caused due to its intervention optical link be minimized, this is the basic demand of the joints of optical fibre.To a certain extent, the reliability of the performance impact of joints of optical fibre optical transmission system and properties.Wherein, Lucent Connector is famous Bell(Bel) institute researchs and develops out, uses easy to operate modular jack (RJ) breech lock mechanism to make.The size of its contact pin used and sleeve is the half of the size used such as common SC, FC, for 1.25mm.So can improve the density of the joints of optical fibre in fibre distribution frame.Currently, in terms of single mode SFF, the adapter of LC type is actual has already taken up leading position, the also rapid development of the application in terms of multimode.
Along with the present LC type joints of optical fibre are more and more universal, people are more and more higher to the requirement of its stability, the oblique 8 degree of angle high return loss Lucent Connectors such as shadow video signal connected, require that its docking angular shift is little, Dissipation change is stable, and prior art does not still have technical scheme perfectly to solve this problem.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of LC type joints of optical fibre, the structure of traditional LC adapter device is modified so that it is docking angular shift is little, and Dissipation change is stable, overcomes the deficiency of prior art.
In order to solve above-mentioned technical problem, this utility model be employed technical scheme comprise that, a kind of LC type joints of optical fibre, body is connected before including, rear connection body, lock pin, pyrocondensation protection pipe, dust cap, spring and tail pipe, dust cap is placed on lock pin, pyrocondensation protection pipe box is in the tail end of lock pin, spring is placed on pyrocondensation protection pipe, pyrocondensation protection pipe, lock pin and spring connect in the cylindrical cavity of body after inserting, front connection body connects on body after being placed on, connect body before described and there is a front opening, one open rearward end and connect front opening and the body of open rearward end, front opening, body and open rearward end are through and arrange, and at this internal formation one accommodation space, it is provided with stopper section in this accommodation space.Stopper section for being limited in procapsid be unlikely to the front opening of prominent front connection body by lock pin.Stopper section can be formed by the structure of the inwall of accommodation space.
Length d1 of front opening and stopper section is 6.19mm.D1 refers to the total length of the longitudinal section of front opening and stopper section, from the right side (away from the side of front opening) in the left side (away from the side of stopper section) of front opening to stopper section.
The length of the mobile space between intrinsic stopper section and rear end window is designated as d2, and in order to further strengthen connection mobile space, the length of d2 is set to 1.95mm.
Further, described body being additionally provided with a groove, this groove is arranged at the upper surface of open rearward end.It addition, the two sides of body are additionally provided with a pair through hole, it is respectively arranged on the both sides of body.
Fastener it is additionally provided with on body, the upper end of body is fixed in one end of this fastener, the free end of fastener can be up and down, whether connects the holding of body by the free end of up and down (press, decontrol action can realize the free end of up and down fastener) fastener before being realized.
It addition, the body of front connection body is a rectangular structure.
When adapter docking connects, due to fiber end face contact, B location of C will be moved rearwards by, traditional LC adapter design defect, docking displacement can be caused, torsiversion is formed docks lateral offset loss！Novel LC adapter increases connection mobile space, effectively secures the accuracy of mobile para-position, especially for the holding effect serving key as the connected mode of the oblique 8 degree of contacts of A point！Rake angle docking can produce strong torsiversion.
This novel scheme is applicable to the Lucent Connector that high stability coupling connects.This utility model passes through such scheme, and by front opening and length d1 of stopper section, length d2 of the mobile space between intrinsic stopper section and rear end window all increases 1mm, increases and connects mobile space, effectively secures the accuracy of mobile para-position.The length of existing front opening and stopper section is generally 5.19mm, mobile space is generally 0.95mm, when traditional adapter docking connects, due to fiber end face contact, the rear end of front opening will be moved rearwards by, the Lucent Connector of existing design length, can cause docking displacement, and torsiversion forms docking lateral offset loss.Basis is the most novel adds 1mm, increases connection mobile space, effectively secures the accuracy of mobile para-position, especially for the holding effect serving key as the connected modes of the oblique 8 degree of contacts of A point！This new structure is simple, is skillfully constructed, and reforming technology is easy, it is easy to promotes, has good practicality.
