Abstract
The utility model relates to a twisted-pair cable on-off tester and aims to solve problems that a traditional cable on-off test instrument has a high price and can be used for measuring only when all cables to be tested are connected with the test instrument. The twisted-pair cable on-off tester is characterized in that: a casing is formed by left and right symmetrical parts of RJ45 sockets, the left part of the casing has an extension groove belt which is in matching use with an L-shaped extension part of the right part of the casing, a lower part of an inner part of the left part of the casing is provided with a cell groove and positive and negative plates of a cell, and indication lamps are mounted in preformed holes at a lower part of the left part of the casing. The twisted-pair cable on-off tester not only can rapidly test an on-off state of a twisted-pair cable, but also has properties of small volume, low cost, high reliability and strong endurance capability.
Description
Technical field
The utility model relates to the Ethernet connection area, especially a kind of twisted pair network cable on off test device.
Background technology
At present, twisted pair network cable has been widely used in the various occasions such as Ethernet, family broadband, office network.Ethernet device, comprise Ethernet card, hub, switch, router, ADSL cat etc., uses 1,2,3,6 in twisted pair network cable as signal wire, and 4,5,7,8 is siding, if situation about opening circuit is arranged in netting twine, can replace reparation.Siding also can branch away and connect another ethernet device simultaneously.Some office is telephone wire and netting twine parallel routing, often can separate four sidings as telephone wire and use.These situations all can make 5,8 these two lines of netting twine not access so, and traditional netting twine on off test instrument does not have return line just can't normally measure yet.
Traditional netting twine on off test instrument must all be connected to detecting instrument to the netting twine two ends and could measure, and in complicated network occasion, often will find in two places which root netting twine mutually corresponding, when netting twine is more, just measures and relatively wastes time and energy like this.The instrument of measuring netting twine has also been arranged, but its price more expensive (tens to hundreds of unit do not wait) on market, and netting twine two of measuring all to be connected to the on off test instrument and could work.
Summary of the invention
High and netting twine to be measured all must be connected to the shortcoming that detecting instrument could be measured while using in order to solve traditional netting twine on off test instrument price, the utility model provides a kind of twisted pair network cable on off test device.
The technical scheme of dealing with problems the utility model proposes is: described a kind of twisted pair network cable on off test device, by shell, pilot lamp and supplying cell, formed, it is characterized in that: shell consists of left and right two parts RJ45 socket of symmetry, and the shell left part has the extension groove band, with shell right side " L " type, extend and be used in conjunction with; Below, shell left part inside arranges battery case and the positive and negative pole plate of battery simultaneously; Pilot lamp is arranged in the below preformed hole of shell left part.
Wherein, described a kind of twisted pair network cable on off test device, be comprised of shell, pilot lamp and supplying cell, it is characterized in that: the positive pole of the pilot lamp on the shell left part all and connect, with the positive pole welding of battery pole plates; The negative pole of pilot lamp is respectively with 1,3,5,7 utmost points of left side socket and connect, and 2,4,6,8 pins of socket are connected in parallel, and in the negative pole welding of battery pole plates.
Wherein, described a kind of twisted pair network cable on off test device, be comprised of shell, pilot lamp and supplying cell, it is characterized in that: 8 pins of the RJ45 socket on the part of shell right side mode of 1 pair 2,3 pairs 6,4 pairs 5,7 pairs 8 respectively join in twos.
The beneficial effects of the utility model are: not only can detect fast the twisted pair network cable on off operating mode, and volume is little, cost is low, and reliability is high, and flying power is strong.
The accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model; Fig. 2 is profile schematic diagram of the present utility model; Fig. 3 is cut-away view of the present utility model.
Wherein, 1. shell left part; 2. shell right side part; 3. pilot lamp; 4. green indicating lamp.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Preferred described pilot lamp (3) adopts LED light; Preferred power unit is three joint LR41 button cells.
Principle of work: use every two lines of twisted-pair feeder as independent measuring circuit, a power supply pilot lamp of series connection (3) is connected in each loop, if two equal normallies of line in this loop, corresponding pilot lamp (3) lamp is bright.Here 8 netting twines are divided into to 4 groups, 1 and 2,3 and 6,4 and 5,7 and 8, as long as 1,2,3,6 these four signal wire conductings of netting twine, two green indicating lamps (4) of instrument are bright, mean that netting twine can normal communication.8 line all-pass, four pilot lamp (3) are entirely bright.
As shown in Fig. 1 ~ 3, twisted pair network cable on off test device, by shell, pilot lamp and supplying cell, formed, wherein, shell consists of two RJ45 sockets symmetrical shell left part (1) and shell right side part (2), and the shell left part has the extension groove band, with shell right side part " L " type, extend and be used in conjunction with; The inner below of shell left part (1) arranges battery case and the positive and negative pole plate of battery simultaneously; Pilot lamp (3) is arranged in the below preformed hole of shell left part (1).
After the anodal all parallel connections of pilot lamp (3) on shell left part (1), welding after being connected with the positive pole of battery pole plates; The negative pole of pilot lamp (3) is 1,3,5,7 extremely in parallel with shell left part (1) socket respectively, and 2,4,6,8 pins of socket also connect together, welding after being connected with the negative pole of battery pole plates.
8 pins of the RJ45 socket on shell right side part (2) are taked respectively: the mode of 1 pair 2,3 pairs 6,4 pairs 5,7 pairs 8 connects rear welding in twos.
In the course of the work, as shown in Fig. 1 circuit, connect two green indicating lamps (4) of 1,3 contacts, 5,7 contacts be blue indicator light.If measure the netting twine break-make situation in the network connection, during the netting twine non-fault, four pilot lamp (3) are entirely bright.
Because in the RJ45 interface of ethernet device, 1,2 pin and 3,6 pin resistance are extremely low, can think conducting state, and this device just can be at these four signal wires of drive test amount netting twine normally whether.If, when netting twine only is connected in ethernet device with four or an end, 1,2 and 3,6 loop communicates, two green indicating lamps (4) are shinny.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
