Description

A kind of the support component of single-ended cable splice closure

Technical field

This utility model relates to a kind of cable splice closure, particularly to a support component of a kind of single-ended cable splice closure.

Background technology

Cable splice closure is a kind of for providing optics, sealing and mechanical strength the successional protection dress that continues between adjacent optical cable Putting, or claim optical cable connecting box, it is mainly at system of layings such as built on stilts, pipeline, the direct-burrieds being applicable to various structure optical cable straight Logical and branch connects.Box body uses engineering plastics, and intensity is high, corrosion-resistant, seals reliable, and easy construction is widely used in communication, net Network system, CATV cable television, cable network system etc..

Notification number is the inner support assembly that the Chinese patent of 205015523U discloses a kind of cap-type optical cable connection box, it Tabletting is fixed including base support, fixed support, strengthening core hook, larynx hoop and optical cable；Described base support installation by adhering exists On the base of cap-type optical cable connection box, base support offers the screw hole matched with base；Described base support side Circumferentially spaced being provided with multiple optical cable fixed bit, optical cable fixed bit is by being positioned at the breach of upper end, being positioned at the fixed support at middle part Installing hole and the larynx hoop installing hole composition being positioned at bottom, breach is used for mounting strengthening core hook, fixed support and strengthening core hook On be provided with the first installing hole matched with fixed support installing hole, fixed support and strengthening core hook upper end are provided with Fix the second installing hole of tabletting for installing optical cable, fixed support bottom is provided with the hook for installing larynx hoop.This patent In the mode that is connected by screw of fixed support be fixed on base support and circumferentially disposed around base support.

This patent is disadvantageous in that: owing to fixed support is circumferentially with some fixing around base support Frame, causes fixed support during installation is fixing, needs to tighten fixing to each fixed support by screw realization respectively； Waste labour force to a certain extent and add the time of mounting and fixing bracket, reducing production efficiency；And it is arranged on the end The screw hole processing worn for some screws on seat support, adds the production cost of mould die sinking in certain degree.

Utility model content

The purpose of this utility model is to provide a kind of sheathed cutting ferrule on base support, and is provided with the side of larynx hoop at Ka Taoshang Formula realizes fixing the binding of optical cable, convenient installation and reduction production cost.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of single-ended fiber cable joint A support component of box, including base support and larynx hoop, described base support is arranged with cutting ferrule, and described card put the end of around The periphery of seat support is circumferentially with some described larynx hoops.

By using technique scheme, cutting ferrule is set on base support and realizes at base by the way of socket Being fixedly installed on support, will be arranged on the optical cable in connector box, and the larynx hoop put by being arranged on card carries out binding to optical cable Fixing；By the way of this kind fixing, make installation fix and operate die sinking cost that is easier and that decrease base support.

This utility model is further arranged to: described cutting ferrule is the flexible piece with two ends and makes two by the way of bending End overlaps to form described cutting ferrule, and screw passes the overlapping of cutting ferrule and is embedded into base support for limiting the axial shifting of cutting ferrule Dynamic.

By using technique scheme, when the larynx hoop that cutting ferrule or card put occurs damaged, owing to connecting on base support It is connected to fusion joining disk, causes the cutting ferrule being set on base support to be not easy from base support to take out；It is bent into by flexible piece Ring body also realizes fixing cutting ferrule by the way of screw is fixing, makes cutting ferrule be easy to dismounting and can also carry out the position of cutting ferrule Limit, increase the practicality that cutting ferrule is arranged.

This utility model is further arranged to: the outer wall of described larynx hoop is provided with outward extending connection post, described connection post Free end be provided with and be axially moveable and wear into cutting ferrule and circumferentially rotate to limit and connect the clamp that moves axially of post for connecting post.

By using technique scheme, by the way of clamp rotates clamping, it is achieved larynx hoop is fixing on card overlaps, and makes larynx The mode removably connected it is embodied as between hoop and cutting ferrule；When making larynx hoop need optical cable is fixed, by larynx hoop from card set Take out, increase the larynx hoop movable space during binding, make the faster and more convenient operation of binding, shorten binding time Between, promote the efficiency produced；The larynx hoop after line will be tied by the way of the clamping rotated, it is achieved fixing on card set.

This utility model is further arranged to: be outward extended with conflict cutting ferrule lower surface on described base support prolongs limit.

By using technique scheme, be arranged on base support after cutting ferrule bending sizing prolongs spacing of limit institute Support, it is achieved cutting ferrule is pre-fixed and facilitates screw to calibrate with the screw hole on base support；Follow-up cutting ferrule is made to fix Operation becomes convenient, shortens the time installing operation further.

This utility model is further arranged to: described larynx hoop be connected between post flexible connection.

By using technique scheme, by the way of flexible connection, the bolt on larynx hoop is made to turn the mistake of locking Cheng Zhong, on movable larynx hoop that can be random, the position of bolt, makes the operation enhanced convenience tightened, and makes bolt in the process tightened In operation will be made more convenient by outside obstruction power.

This utility model is further arranged to: described flexible connection be be connected post fix connection and be set on larynx hoop The collar.

By using technique scheme, larynx hoop is placed through connecting the ring set on post, it is achieved the activity on card set is even Connect, make larynx hoop use during the position of bolt on larynx hoop can be carried out random regulation, be adjusted to conveniently rotate add The position of work, the locking making larynx hoop is convenient.

This utility model is further arranged to: described cutting ferrule has caved inward for clamp rotation towards the one side of base support Accommodating cavity volume.

By using technique scheme, when the setting of cavity volume makes to be fastened in grip base support, will not be because of applying Clamping force is excessive and causes the gap between cutting ferrule and base support too small, and has influence on normally wearing and normally turning of clamp Dynamic.

This utility model is further arranged to: one end of described cutting ferrule is provided with and is formed for fixing cutting ferrule for other end clamping Circumferentially fixed draw-in groove.

By using technique scheme, one end of cutting ferrule is by draw-in groove clamping on an opposite end, it is achieved form cutting ferrule Pre-fixing of ring body, is fixed on cutting ferrule on base support by the way of this kind pre-fixes, and facilitates follow-up screw-driving reality Now cutting ferrule is fixed, make operation more convenient.

In sum, this utility model is had the advantages that and is directly set on base support by cutting ferrule, is formed Larynx hoop fixing on base support, realizes the line of optical cable fixing the ligation of line by the way of larynx hoop is locked, makes operation More convenient and reduce the die sinking cost of mould；It is removable that larynx hoop realizes by the way of clamp circumferentially rotates between cutting ferrule Unload connection, larynx hoop can be taken out from card set and line is tied up, be lifted at the activity space of hand during tying up, make operation More convenient.
