Abstract

An LC single-connecting integrated optical fiber connector is used for the optical fiber connection in a photoconductive communication facility, and comprises an inserted section and an inserting section. The utility model is characterized in that the inserted part comprises an external shell of the whole optical fiber connector. A metal conduit is embedded at one end of the inserting section, while the other end is connected with an inserting hole at the inserted section. Moreover, the inserting section is formed by connecting with a buckling-connection hole in the way of buckling via a buckle part. One end wall is end wall of the embedded metal tube of the inserting section is equipped with a notch. The utility model changes the connecting manner of a prior optical fiber connector, which requires butting-connection of two sections of external shell, into the internal plug-in connection in the whole external shell, which ensures the outlook color is consistent and the shell is free of separating seams. Meanwhile, as a notch is arranged in the internal plug-in part, the part is contractible or extensible correspondingly and will not press the external shell hardly to cause cracks.

Description

LC simply connected integral fibre-optic connector

Technical field

The utility model relates to the components and parts in the optical communications field, especially relates to a kind of simply connected joints of optical fibre.

Background technology

At present at the LC simply connected joints of optical fibre of using, shown in accompanying drawing 1--3, be that two parts snapping by butt joint gets up, the shell body internal fixation has the metal catheter that optical fiber is installed, and is used for connecting optical fiber and is fixed; Though this scheme can realize the connection of optical fiber preferably, but remain in following problems: the one, because joints of optical fibre volume is little, outer shell walls is very thin, in the time of in a part is inserted another part housing, tends to the crack occur at the snapping place that is inserted into partial shell; The 2nd, the part termination of going to insert is embedded with metal catheter, because of housing by plastic production, and metal catheter is made by metal, when under the same process condition, the termination is embedded with the color of the partial shell outer wall of metal catheter can be inconsistent with the housing color of another part, influences outward appearance; The 3rd, have tangible gap at the joint of two parts shell body, also influence the attractive in appearance of profile.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, a kind of LC simply connected integral fibre-optic connector of novel structure to be provided, not ftractureing good looking appearance to reach.

For achieving the above object, the technical solution of the utility model is such: a kind of LC simply connected integral fibre-optic connector comprises being inserted into part and removing insertion portion the said shell body that partly comprises the overall optical fiber connector that is inserted into; The said insertion portion that goes is the plug-in part that is embedded with metal catheter, the going to insert and have groove on the end wall and lack of this plug-in part, and in order to elastic telescopic,

Owing to adopted technique scheme, a kind of LC simply connected integral fibre-optic connector of the present utility model has changed the connecting mode that the former joints of optical fibre need two parts shell body to connect, and the plug-in part that becomes in monolithic case connects, guaranteed the appearance luster unanimity, no gap; Simultaneously scarce because of groove is set on plug-in part, can adapt to flexible, can rigid extruding shell and cause cracking.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 be background technology the LC simply connected joints of optical fibre be inserted into the part-structure synoptic diagram.

Fig. 2 be background technology the LC simply connected joints of optical fibre remove the insertion portion structural representation.

Among the figure: 1, shell body, 2, patchhole, 3, the snapping hole, 4, shell body, 5, fastener, 6, metal catheter, 7, the shell body seam, 8, shell body, 9, the snapping hole, 10, patchhole, 11, groove lacks, 12, metal catheter, 13, fastener.

Embodiment

Shown in Figure 3 by Fig. 1 one, be the LC simply connected joints of optical fibre of background technology, it comprises and is inserted into part and removes insertion portion, two parts all include

shell

1,4, wherein go insertion portion one end to be embedded with metal catheter 6, connect with patchhole 2 by the other end, and form by fastener 5 and snapping hole 3 snappings.This structure exists following problems: the one, because joints of optical fibre volume is little, outer shell walls is very thin, in the time of in a part is inserted another part housing, tends to the crack occur at the snapping place that is inserted into partial shell; The 2nd, the part termination of going to insert is embedded with metal catheter 6, because of housing by plastic production, and metal catheter is made by metal, when under the same process condition, the termination is embedded with the color of the partial shell outer wall of metal catheter can be inconsistent with the housing color of another part, influences outward appearance; The 3rd, body seam 7 places have tangible gap outside, also influence the attractive in appearance of profile.

By Fig. 4--shown in 6, a kind of LC simply connected integral fibre-optic connector of the present utility model comprises being inserted into part and removing insertion portion the said shell body 8 that partly comprises the overall optical fiber connector that is inserted into; Said insertion portion one end that goes is embedded with metal catheter 12, is connected with patchhole 10 on being inserted into part by the other end, and forms by fastener 13 and snapping hole 9 snappings; For preventing rigid extruding shell body, remove to have on another end wall of insertion portion groove at said this and lack 11, in order to elastic telescopic.

Claims

1. a LC simply connected integral fibre-optic connector comprises being inserted into part and removing insertion portion, it is characterized in that: the said shell body (8) that partly comprises the overall optical fiber connector that is inserted into; Said insertion portion one end that goes is embedded with metal catheter (12), is connected with patchhole (10) on being inserted into part by the other end, and forms by fastener (13) and snapping hole (9) snapping; On said not engaged column conduit one end wall that removes insertion portion, have groove and lack (11).
