Abstract

It the present invention relates to the use of the DC loop that four cores and other end Registered Jack-45 in network cable are constituted, carry out the device of test network cable core connectivity.Network cable is connection both ends Registered Jack-45, as long as extracting one end RJ-45 plug (being commonly called as crystal head) when test is inserted into the tester, viewing lamp is bright or goes out, it is known that corresponding core is on-off.Network cable has 8 cores, only 1,2,3, the connection of 6 cores can normal communication, so three indicator lights of observation are that all light can determine whether the intact connection of cable.In test, three indicator lights are observed wherein if there is not working, flashing or brightness is dimer, shows that cable is bad, corresponding bad core is found according to indicator light and is repaired.The tester inspection that whether good, cable core breaks especially suitable for the crystal head core contact point that checks network cable pliers compacting.

Description

Small and exquisite simplicity network cable tester

Technical field

It the present invention relates to the use of the DC loop that four cores and other end Registered Jack-45 in network cable are constituted, come The device of test network cable core connectivity.

Background technique

It is had the following drawbacks when computer network cable maintenance personal excludes cable connected trouble usually using the work of test: Detection is slower, and volume is larger, cumbersome, forgets to close tester power supply, battery consumption is too fast.Inventing the tester can overcome These drawbacks.

Summary of the invention

Network cable is connection both ends RJ-45 socket, as long as extracting one end RJ-45 plug (being commonly called as crystal head) when test It is inserted into the tester, viewing lamp is bright or goes out, it is known that corresponding core is on-off.Network cable has 8 cores, only 1, 2,3,6 cores connection can normal communication, so observation three indicator lights be that all light can determine whether the intact connection of cable.It is testing When, three indicator lights are observed wherein if there is not working, flashing or brightness is dimer, are shown that cable is bad, are looked for according to indicator light It is repaired to corresponding bad core.The tester especially suitable for check network cable pliers compacting crystal head core contact point be The inspection whether no good, cable core breaks.

The effect of two contact line terminals is to test the core for not loading onto crystal head.Application method: will be in the contact of two cores Terminal, the cable other end are inserted on other Registered Jack-45, and whether viewing lamp (2) lights, and has lighted and has shown two cores all It is logical.

The effect of contact button is: 1, whether test battery has electricity to press button indicating lamp and lights, show that battery has electricity Amount.2, direct current electrical circuit public line replacement altogether, when test cable, if three indicator lights all do not work it is necessary to press contact button into One pacing examination.

Detailed description of the invention

Fig. 1 is pictorial diagram of the invention;

Fig. 2 is the principle of the present invention figure;

Fig. 3 is process for using of the invention, decision logic figure.

Specific embodiment

Network cable is connection both ends RJ-45 socket, as long as extracting one end RJ-45 plug (being commonly called as crystal head) when test The tester is inserted, beacon lamp is now examined.Three indicator light all lights indicate that 4 line all-pass are intact, if indicator light therein does not work, Represent corresponding 1,2,3 broken strings；Or there is flashing, brightness ratio are darker to show that corresponding core poor contact, resistance are excessive.

If the 6th line (the total public line of direct current electrical circuit) is obstructed, indicator light does not work all, needs to press contact button further Detection.Three indicator light all lights when lower button, then representing is the 6th obstructed, other three lines are logical.If only 2 lamps are bright Indicate that 4 wholes are disconnected or 2,6 lines break.

The tester can also not load onto the core of crystal head directly, and tester terminal in two end in contact of core is seen It examines whether indicator light (2) lights, has lighted and shown that two cores are all logical.Do not need wire stripping in actual use, the end of a thread always some Few metal part exposure, so connecing true terminal can be with contact wire conduction, compared with more than universal meter convenient test.

Use the tester benefit: (1) quickly detection insertion network wire crystal joint i.e. known to inspection result, plug and play from Switch.(2) small and exquisite easy to carry, volume only has 2 cubic centimetres or so to be equivalent to USB flash disk size.(3) battery is long, only It is test indicator light moment consumption electric energy, extraction cable is then fully powered-off, does not have to change battery usually using several years.

Claims

1. small and exquisite simplicity network cable tester, is made of following element: RJ-45 socket, three LED indicator lights, 2032 button batteries, current-limiting resistance, contact button.

2. it is characterized in that: RJ-45 socket pins 1,2,3 are connected with three indicator light anode pins respectively, three indicator light negative terminals Pin is connect by current-limiting resistance with battery cathode；RJ-45 socket pins 6 connect anode, one pin of contact button, one Contact line terminals；Another pin of contact button, another contact line terminals connect RJ-45 socket pins 2.

3. the tester is using the DC loop of four cores and other end Registered Jack-45 composition in network cable, to survey Try core connectivity.
