Abstract

The utility model relates to cable transmission auxiliary equipment which protects an optical fiber connector, in particular to an underground manhole installation cable connector box with a built-in optical splitter, which comprises a cylindrical shell and a base which are sleeved and connected in a sealing way; the base is provided with a multi-core cable in and out tube and a plurality of household cable in and out tubes; a permanent seat is fixed on the upper surface of the base; a rectangular box is fixed on the permanent seat; and the optical splitter and a plurality of splice trays are arranged in the box. The underground manhole installation cable connector box is provided with the 1:N module type optical splitter and a plurality of splice trays; the input end of the splitter is a tail optical fiber which is directly fused with a trunk fiber, outputs a flange terminal, is movably connected with the household optical fiber, can fuse a household cable into an end or a field connector into an end, not only has the cable continuous connection function and directly lead out the wiring cable, but also can connect and split the cable without breaking the cable; in addition, the trunk fiber is fused into an end and the household optical fiber is fused into an end in different areas, for the convenience of construction and maintenance.

Description

A kind of ground servant's well of built in light shunt is installed cable splice closure

Technical field

The utility model relates to the optical cable transmission support equipment that fibre-optical splice is shielded, and is that a kind of ground servant's well of built in light shunt is installed cable splice closure.

Background technology

Along with popularizing of FTTx, a variety of cable splice closures arise at the historic moment, have outdoor, indoor, also there are wall hanging installing type, built on stilts installing type, people's well mounted, but all have only simple optical cable continued access or difference function, and traditional difference need all cut off optical cable, both increased engineering time and fused fiber splice cost, also influenced communication quality.

The utility model content

Technical problem to be solved in the utility model is to solve cable splice closure to have only simple optical cable continued access or difference function, and optical cable all need be cut off when carrying out difference in box, has increased the problem of engineering time and fused fiber splice cost.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of ground servant's well of built in light shunt cable splice closure is installed, comprise tubular shell and base that suit is tightly connected, base is provided with a multifiber cable turnover pipe and some optical cable turnover pipes of registering one's residence, the upper surface of base is fixed a holder, be fixed with a rectangular-shaped box body on this holder, the built-in optical branching device of this box body and some fibre melting discs.

In the such scheme, described optical branching device is a 1:N modular optical shunt, and described fibre melting disc quantity is three.

The xsect of described multifiber cable turnover pipe be oval, and the described optical cable turnover pipe of registering one's residence is that eight and its xsect are circle.

Described base and housing seal by anchor ear locking and by O-ring seal.

The utility model, be built-in with 1:N modular optical shunt and 3 fibre melting discs, the shunt input end is a tail optical fiber, be used for directly with the trunk optical fiber welding, the output flange terminal, flexibly connect with Drop cable, be convenient to jump logical link in real time for the user of business to be installed, the optical cable of registering one's residence can be fused into end or field connector Cheng Duan, not only have optical cable continued access function, directly the wiring lead optical cable, and can under the situation of continuous cable, draw and connect difference, draw the various optical cables of registering one's residence, trunk optical fiber is fused into end and Drop cable and is fused into and holds subregion to carry out, and is convenient to construction maintenance.

Fig. 2 is an inner structure synoptic diagram of the present utility model;

Fig. 3 is the upward view of cable splice closure among Fig. 1;

Fig. 4 is the anchor ear structural representation.

Among the figure:

1-housing, 2-O-ring seal, 3-multifiber cable turnover pipe, the 4-optical cable turnover pipe of registering one's residence, the box body of 5-built in light shunt and fibre melting disc, the 6-holder, 7-snap close set collar, the 8-snap close is ring seat fixedly, 9-turning axle, 10-base.

Embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

As Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises tubular shell 1 and the base 10 that suit is tightly connected, base 10 is provided with 3 and eight circles of oval multifiber cable turnover pipe optical cable turnover pipe 4 of registering one's residence, the upper surface of base 10 is fixed a holder 6, be fixed with a rectangular-shaped box body 5 on this holder 6, these box body 5 built-in three fibre melting discs and optical branching devices.Described optical branching device is a 1:N modular optical shunt, and base 10 and housing 1 are by anchor ear locking and by O-ring seal 2 sealings.

The xsect of described multifiber cable turnover pipe 3 be an ellipse, can support not cut off optical cable and realizes that the backbone optical cable difference promptly realizes drawing connecing; The described optical cable turnover pipe 4 of registering one's residence be eight and its xsect for circular, can insert simultaneously for the user on eight shunt output ports.

In work progress, multifiber cable enters box body 1 from ellipticity optical cable turnover pipe 3, the optical cable of registering one's residence enters box body 1 from round mouth optical cable turnover pipe 4, by the wiring lead optical cable behind the optical cable that continues of the fibre melting discs in the rectangular-shaped box body 5, to can draw the optical cable of registering one's residence behind the fused fiber splice in the difference optical fiber that cut off and the optical cable of registering one's residence, optical branching devices in the rectangular-shaped box body 5 can carry out beam split, and base 10 is contained in after the box body 1, by anchor ear box body 1 and base 10 are tightly locked sealing.

As shown in Figure 4, wherein the tight lock seal operation of anchor ear is: the openings of sizes of turning axle 9 rotatable control anchor ears, the anchor ear opening is rotated to be maximum, be enclosed within box body O-ring seal 2 places, again with snap close set collar 7 and clasp fixedly ring seat 8 overlap, screw down sealing.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
