Abstract

The utility model relates to an optical fiber connector of LC twin one-piece type, which is used for the optical fiber connection in light guide communication device, comprising a plug-in unit and an insert. Wherein, the plug-in unit comprises the whole hull body of the twin optical fiber connector with an inserting hole of the insert and a connection hole arranged on the hull body; the insert is an interpolating piece embedded with two parallel metal guide tubes. A fastening buckle is arranged at one end of the insert with no metal guide tube to connect the insert with the inserting hole, and fasten the fastening buckle and the connection hole. The utility model combines the hull of the original twin optical fiber connector and the connection bracket as a whole, and the insert embedded with metal guide tube has no hull body. The original twin optical fiber connector needs consists of five parts, adopting the connecting mode of opposite connection of the hull body with five procedures to manufacture, which changes into two parts, thereby reducing the cost and guaranteeing the unification of the appearance and color by adopting the interpolating piece connection in the whole hull.

Description

LC duplex 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 duplex joints of optical fibre.

Background technology

The present LC duplex joints of optical fibre of using, shown in accompanying drawing 1-4, the insert that is subjected to be embedded with on plug-in unit and the shell body metal catheter that has shell body that comprises butt joint, and the connecting rack formation, each duplex joints of optical fibre needs be subjected to plug-in unit, a connecting rack by two, two insert five parts assemble, need five processes during manufacturing, processing and assembling are complicated, the cost height; Be embedded with metal catheter on the insert because of the band shell body simultaneously, housing is 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.

Summary of the invention

The utility model is in order to overcome the deficiency of above-mentioned prior art, a kind of LC duplex integral fibre-optic connector of novel structure to be provided, and simple to reach operation, cost is low, the purpose of good looking appearance.

For achieving the above object, the technical solution of the utility model is such: a kind of LC duplex integral fibre-optic connector comprises being subjected to plug-in unit and insert the said shell body that is subjected to plug-in unit to comprise the whole duplex joints of optical fibre, housing is provided with the patchhole of insert, and the snapping hole; Said insert is the plug-in part that is embedded with two metal catheters arranged side by side, is not provided with fastener on engaged column conduit one end wall at insert, insert is connected with patchhole, and with fastener and the fastening of snapping hole.

Owing to adopted technique scheme, a kind of LC duplex integral fibre-optic connector of the present utility model becomes one the shell and the connecting rack merging of the former duplex joints of optical fibre, is embedded with on the insert of metal catheter and is not with shell body; Make the former duplex joints of optical fibre need to form by five parts, and the connecting mode that adopts shell body to connect, need through five processes processing, changing to become only needs two parts, has reduced cost; The plug-in part of employing in monolithic case connects, and guaranteed the appearance luster unanimity.
