Description

A kind of net tail sheath and fiber active linker

Technical field

The utility model relates to a kind of optical patchcord device, specifically a kind of net tail sheath and fiber active linker.

Background technique

Optical patchcord is used to do the jumper from equipment to optical fiber cloth wired link, has thicker protective layer, is commonly used in Connection between optical transmitter and receiver and termination box is applied in optical fiber telecommunications system, Optical Access Network, fibre optic data transmission and local area network Etc. some fields.

Now 100% twin fiber cable LC optical patchcord all uses the net tail being separately separated in the market, these net tails cannot Anchor tip is swung left and right, and is easy to change the insertion width of interface, causes insertion to have some setbacks, be not sufficiently stable and precisely.Due to It is independent net tail, is to separate design in tail portion, cable is unavoidable bifurcated, uneven in length problem occurs, will cause micro-bend damage It consumes excessive, causes product data unqualified, and keep the appearance of product entirety inadequate.More due to having used seperated design, two are connect Head can left and right intermodulation, it is easy to occur cross-combining bring intersect it is obstructed.

Utility model content

The purpose of this utility model is to provide a kind of net tail sheath and fiber active linkers, to solve above-mentioned background skill The problem of being proposed in art.

To achieve the above object, the utility model provides the following technical solutions:

A kind of net tail sheath, base portion and sheath section, the base portion and sheath section including linking together and keeping connection End face on offer location hole and entrance hole respectively, the quantity of the location hole and entrance hole is respectively two and one.

The base portion and sheath section are made into integration using plastic material as a further solution of the present invention,.

Be also equipped between the base portion and sheath section as a further solution of the present invention, for core wire into The separated furcation of row.

The furcation is v-shaped structure as a further solution of the present invention, and tip is opposite with entrance hole, The other end is opposite with location hole.

As a further solution of the present invention, the sheath section from the junction of base portion to far from base portion to It inside gradually restrains, the shape and sheath section profiling of entrance hole.

The surface hollow-out setting of the sheath section as a further solution of the present invention,.

The inner wall of the entrance hole is hexagon, and hexagon adjacent two as a further solution of the present invention, With arc transition between side, so that the thickness of sheath section continuously alternately changes.

The junction of hexagon adjacent edge thickness compared at the rest of is thin as a further solution of the present invention,.

A kind of fiber active linker comprising net tail sheath as described above.

Compared with prior art, the utility model has the beneficial effects that twin-core cable is enabled to close naturally in insertion And and naturally expose from two location holes after furcation, the plug width of duplexing connector is fixed with this, and then carry out Position duplex interface, avoid duplex interface be separated wave be not fixed caused by connection plug size distortion problem, cause to connect It patches into the phenomenon having some setbacks, data connection is unstable；Moreover, the design of " small rough waist " structure and thickness design of sheath section, energy Push-in difficulty is effectively reduced, while sheath section can be waved arbitrarily when not being routed, sufficiently avoids cable bend radius is too small from making At breakage phenomenon, effective protection cable.
