Description

Exempt from terminating network hunting device based on actinobolia

Technical field:

The utility model relates to a kind of generic cabling engineering network hunting technology, more particularly to a kind of based on actinobolia Exempt from terminating network hunting device.

Background technique:

With the development of information telecommunications, comprehensive wiring system is made of as a kind of communication cable and connection hardware Basic weak electricity system has been used widely in the development of urban informationization.For convenient for managing and maintaining, " comprehensive wiring system Engineering design code GB 50311-2016 " composition such as regulation each cable of comprehensive wiring, optical cable, distribution plant, termination point Part should all give unique identifier, and label should be arranged, and the both ends of cable and optical cable should all indicate identical identifier.From Construction angle is said, is laid before cable it is ensured that both ends and is carried out cable mark.For the pair twist cable in wiring subsystem, if It completes to lay in the case where no stickup cable mark, then needs to carry out identification correspondence to cable both ends using hunting instrument, it is no It then will form chaotic wiring.And current line-hunting method must be just implementable after one end Cheng Duan of cable, that is, needs to pacify Dress crystal connector terminates to cable on network wiring frame or information socket module.This situation changes in comprehensive wiring system Make or the nonstandard engineering construction of process in it is relatively common.If being related to number of cables much especially with Shielded Twisted Pair When, this tradition hunting scheme can then expend many time and manpower, reduce construction efficiency, result in waste of resources.

Utility model content:

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide it is a kind of design rationally, energy It is enough conveniently and efficiently for search paired cable that both ends do not terminate, can also relax cable laying and mark are made it is successive It is required that, so that the flexibility of construction stronger is exempted from terminating network hunting device based on actinobolia.

The technical solution of the utility model is:

It is a kind of that terminating network hunting device is exempted from based on actinobolia, including four pairs of unshielded twisted pairs, RJ-45 connector and One end of the induction spool of C-shaped, four pairs of unshielded twisted pairs is installed together with RJ-45 connector, the RJ-45 connector with The connection of network hunting instrument, extracts a line pair from the other end of four pairs of unshielded twisted pairs, around C-shaped wall cross-section It is closely wound, axially turns to C-shaped coil along pipe, when hunting, the induction spool that will be sought cable and be embedded in the C-shaped opens letter Number generator, audio signal are injected the metallic conductor of insertion cable inside the induction spool of the C-shaped by induction, and along cable It propagates, can be positioned in cable other end search audio signal to being sought cable with hunting instrument signal receiver.

Adhering to one layer of aluminium foil on the surface of the induction spool of the C-shaped makes the C-shaped to increase effectiveness Incude and obtains stronger electromagnetic signal inside spool；Since network hunting instrument is input to by kinking to the signal polarity in both threads Must be identical, therefore situation must be exported according to the signal of heterogeneous networks hunting instrument when installing RJ-45 connector and adjust line sequence.

One layer of PVC flexible film is covered with outside the coil, prevent the coil slided on tube wall deformation and by Abrasion.

The line of induction tube outside of the C-shaped installs one layer of rigid plastic shell, the fixed part of the plastic shell and work additional Dynamic part is connected by hinge arrangement, and the end of the movable part is bonded with rubber tent, cable of the latter to insertion spool Play limitation fixed function.

The induction spool of the C-shaped is made of polyethylene, internal diameter 12-16mm, and Opening length 6-8mm can Support that insertion five classes to seven class twisted pairs, spool winding portion length are 15cm.

The beneficial effects of the utility model are:

1, the utility model is tested cable input audio signal using induction normal direction, replaces traditional direct injection, adopts With semi-enclosed coil, injection audio signal can be incuded from any position of cable, does not destroy cable oversheath, it is not necessary to it is required that from Coil is penetrated at cable end, using flexible is quick.

2, when the utility model carries out Shielded Twisted Pair hunting, injection cable audio signal and signal generator output signal Intensity is almost equal.When carrying out unshielded twisted pair hunting, injection cable audio signal and signal generator output signal strength Difference is that the 10-20dB(value is related with cable insulation material), decaying is relatively large, but from acoustically still there is preferable resolution Effect；If the sound gain amplifier 10-20dB of hunting instrument receiver can be improved, reach the effect same with traditional line-hunting method Fruit.

3, the utility model respectively adheres to the aluminium foil of one layer of 0.5mm in the two sides of polyethylene tube wall, to increase electromagnetic shielding effect Fruit makes to obtain stronger electromagnetic signal inside c-type spool, overcomes outer coil on c-type spool to the electromagnetic field of inner coil It offsets an influence.

4, the utility model is covered with the PVC flexible film of one layer of 0.2mm outside coil, effectively prevent coil on tube wall Sliding is deformed and is worn.

5, the online tube outside of the utility model installs one layer of rigid plastic shell additional, further protects wire tube structure, outside plastics The fixed part of shell is connected with movable part by hinge arrangement, and the end of movable part is bonded with rubber tent, and the latter is to embedding The cable for entering spool plays certain limitation fixed function.

6, the utility model is not only suitable for shielding and unshielded twisted pair, and can expand the letter for other with metal core Number line, power supply line and optical cable with metallic strength member etc., can expand the use scope of traditional hunting instrument, reality easy to spread significantly It applies, it is with good economic efficiency.
