Abstract

The utility model relates to a novel hot-melt-type rapid connector and more specifically relates to the technical field of a fiber connecting device. The novel hot-melt-type rapid connector comprises a protective housing (1), an outer frame (2), an inner core stand (3), a thermal shrinkable sleeve tail handle (4), a ceramic insertion core tail stand (5), a ceramic insertion core (6), an inner core (7) and a dustproof cap (8). The outer frame (2) is sleeved on the front end of the protective housing (1), the inner core stand (3) is arranged inside the front end of the outer frame (2), the thermal shrinkable sleeve tail handle (4) is arranged on the front end of the inner core stand (3), the ceramic insertion core tail stand (5) is disposed on the front end of the thermal shrinkable sleeve tail handle (4), the ceramic insertion core (6) is disposed on the front end of the ceramic insertion core tail stand (5), the inner core (7) is disposed on the front end of the ceramic insertion core (6), and the dustproof cap (8) is disposed on the front end of the inner core (7). The novel hot-melt-type rapid connector exhibits high reliability, and the insertion core is directly connected with a covered wire so that a fiber is not liable to break when the insertion core is blocked and withdrawn.

Description

A kind of novel heat molten type quick coupler

Technical field:

The utility model relates to the optical fiber splicing device technical field, is specifically related to a kind of novel heat molten type quick coupler.

Background technology:

Along with people growing to communication bandwidth requirements, optical fiber has been used for wireline communication network in a large number, in the construction of fiber optic network, need make the joints of optical fibre at optical fiber end, traditional joints of optical fibre are in factory's preprocessing, and what the hot melt splicing point field optical fibers connector that the utility model adopts adopted is the form of making joints of optical fibre at the construction field (site) by welding.

The field optical fibers connector that the hot melt that uses in the present optical fiber engineering continues mainly adopts the mode of stepping up covered wire cable, makes covered wire cable be connected with connector shell.But the major defect of existing this structure is: in case optical fiber penetrates in the adapter, ceramic insertion core can produce rollback, if and covered wire cable and shell relative fixed, do not give the heat-shrinkable T bush retraction space, optical fiber and heat-shrinkable T bush junction will produce stress and concentrate, until fractureing.

The utility model content:

The purpose of this utility model provides a kind of novel heat molten type quick coupler, the mode of its employing thermal welding is made connector at the construction field (site) has the loss of insertion accurately to assess, and obtain lower connecting loss, and the stronger advantage of reliability, and lock pin directly links to each other with rubber-insulated wire and compares with the connector of existing heat molten type, the lock pin not frangibility of optical fiber that is hampered in the back off procedure.

In order to solve the existing problem of background technology; the utility model is by the following technical solutions: it comprises protecting sheathing 1; housing 2; internal core print seat 3; heat-shrinkable T bush caudal peduncle 4; ceramic insertion core tailstock 5; ceramic insertion core 6; inner core 7; dust cap 8; the front end sleeve of described protecting sheathing 1 is connected to housing 2; the front end inside of housing 2 is provided with internal core print seat 3; internal core print seat 3 front ends are provided with heat-shrinkable T bush caudal peduncle 4; the front end of heat-shrinkable T bush caudal peduncle 4 is provided with ceramic insertion core tailstock 5; the front end of ceramic insertion core tailstock 5 is provided with ceramic insertion core 6; the front end of ceramic insertion core 6 is provided with inner core 7, and inner core 7 front ends are provided with dust cap 8.

The utlity model has following beneficial effect: the length of protecting sheathing is greater than the length of heat-shrinkable T bush, in case heat-shrinkable T bush rollback heat-shrinkable T bush has sufficient retraction space in protecting sheathing; Ceramic insertion core directly is connected with heat-shrinkable T bush by plug core tail handle, heat-shrinkable T bush caudal peduncle, and the ceramic insertion core rollback can promote heat-shrinkable T bush; A housing, an inner core of using, an internal core print seat, a ceramic insertion core, a ceramic insertion core caudal peduncle all are the standard components of the factory-assembled joints of optical fibre, thereby have reduced cost.

Description of drawings:

Fig. 1 is the utility model structural representation.

Embodiment:

Referring to Fig. 1; this embodiment is by the following technical solutions: it comprises protecting sheathing 1; housing 2; internal core print seat 3; heat-shrinkable T bush caudal peduncle 4; ceramic insertion core tailstock 5; ceramic insertion core 6; inner core 7; dust cap 8; the front end sleeve of described protecting sheathing 1 is connected to housing 2; the front end inside of housing 2 is provided with internal core print seat 3; internal core print seat 3 front ends are provided with heat-shrinkable T bush caudal peduncle 4; the front end of heat-shrinkable T bush caudal peduncle 4 is provided with ceramic insertion core tailstock 5; the front end of ceramic insertion core tailstock 5 is provided with ceramic insertion core 6; the front end of ceramic insertion core 6 is provided with inner core 7, and inner core 7 front ends are provided with dust cap 8.

The field fabrication process of the field optical fibers connector that hot melt of the present utility model continues may further comprise the steps: 1, with the special-purpose sheath that the line pincers break the optical cable of registering one's residence of broadcasting, expose the optical fiber that one section diameter is 250 microns band coat;

2, peel off the optical cable and optical fibres coat of registering one's residence, expose diameter and be 125 microns bare fibre;

3, peel off the optical fiber coating that is embedded in the lock pin, expose diameter and be 125 microns bare fibre;

4, will open and dial the good optical cable and be embedded in fused fiber splice in the lock pin of registering one's residence;

5, welding point is protected with heat-shrinkable T bush;

6, protecting sheathing is connected with the inner core base, with the protection heat-shrinkable T bush.

This embodiment has following beneficial effect: the length of protecting sheathing is greater than the length of heat-shrinkable T bush, in case heat-shrinkable T bush rollback heat-shrinkable T bush has sufficient retraction space in protecting sheathing; Ceramic insertion core directly is connected with heat-shrinkable T bush by plug core tail handle, heat-shrinkable T bush caudal peduncle, and the ceramic insertion core rollback can promote heat-shrinkable T bush; A housing, an inner core of using, an internal core print seat, a ceramic insertion core, a ceramic insertion core caudal peduncle all are the standard components of the factory-assembled joints of optical fibre, thereby have reduced cost.
