Description

Grid line is made and the experiments of measuring device

Under technical field: the utility model belongs to the teaching experimental equipment of a kind of computing machine and network facet, and particularly university, vocational school and training department, enterprise carry out professional's education experiment of computing machine and network facet and grid line that operation training is used is made and the experiments of measuring device.

Technical background: when communication and computer network system wiring, not only quantity is many, and the diameter of lead is little.For example computer network system grid line commonly used is made up of 8 cores, the quartzy plug connecting line of 8 lines is arranged and be connected grid line by the loop line frame, for connecting grid line by the loop line frame is to carry out in such a way, per two cores form 4 pairs of twisted-pair feeders according to certain standard pitch multiple twin, then these four pairs of twisted-pair feeders are twisted into a lead according to the certain standard pitch again.When two leads continued, an end must connect by the module of standard, and the other end must connect by the RJ45 head.Strand line strip off together must be connected with the RJ45 joint when being connected, then the RJ45 head be inserted on the equipment with equipment.

Wiring when being connected with the RJ45 head by module must adopt the line ball mode to realize.Concrete grammar is: the 8 core grid lines that will need wiring are at four pairs of multiple twins of termination elder generation's strip off, and two pairs of multiple twins of strip off again sequence according to the line preface and the colour code of standard code.

When being connected, earlier 8 heart yearns are pressed onto in 8 connection jaws of module according to the line preface, use special line ball instrument then, line pressure is gone in two metal blades of connection jaws with module.In the process that line pressure is gone into, two blades on the module prescind the external insulation crust of line, and the copper conductor core is contacted with metal blade, and two rubber-like blades clamp copper core, realization contact conduction.

When connecting by the RJ45 head, earlier 8 heart yearns being sequenced, manage directly according to the line preface, has one's hair trimmed in the termination, insert in the RJ45 module, use special Crimping Pliers then, 8 blades on the module are pressed into lead, the outer plastic insulation skin that makes blade scratch every heart yearn contacts with the copper core, realizes the contact conduction.

In above operating process, line preface mistake appears easily, and method of press-fitting is incorrect, and blade does not prescind insulated hull, and perhaps blade is not pressed in the lead, can not switch on.Have only practical operation training by some, could correct wiring.The special instrument of practical operation training need detects, and the grid line making also has specific purpose tool processing, is familiar with and understands the use of these specific purpose tools, all is can to learn and understand after work generally speaking.And for the personnel of computing machine and relevant speciality, in school study and during training, because these special detection instruments can only be supplied with a people and use, it is too big to offer this type of experimental expenses, and experiment can't be offered.

The quality that connects for the quartzy plug of 8 lines is to use the special measurement instrument, the special measurement instrument is divided into two parts, part fixed network socket 568A, another part fixed network socket 568B, behind network socket 568A, the 568B with the quartzy plug reeve of 8 cores two ends, can directly show the quality of the quartzy plug of 8 cores.After the quartzy plug of 8 cores is made, dispatch from the factory after general available dedicated surveying instrument measurement is qualified.But relate to the quartzy plug of making 8 cores for carrying out network experiment, particularly network experiment, adopt instrumentation to carry out test experience, price is too high on the one hand, once can only be operated by a people on the other hand, and is very inconvenient.

Summary of the invention: the purpose of this utility model provides a kind of grid line and makes and the experiments of measuring device, and its expense is low, can satisfy a plurality of people simultaneously tests and test.

The purpose of this utility model is achieved in that grid line making and experiments of measuring device, it is made up of network socket, the loop line frame of pairing, holder, the display device of pairing, it is characterized in that: the loop line frame of the network socket of pairing, pairing is fixed on the holder upper surface, be fixed with display device on the holder, control panel is fixed in the holder, the network socket of pairing, the loop line frame of pairing are connected in series by corresponding grid line and display device, the corresponding display unit of the every corresponding display device of grid line.

Described display device has with the position display unit of the loop line frame equal number of network socket, the pairing of pairing to be formed, each display unit has two LED, two LED are connected on respectively and the corresponding grid line of network socket two ends, wherein the network conductors of two corresponding numberings of LED.

Be connected with positive supply again after grid line one end and the one group of LED serial connection, grid line other end connection control circuit, control circuit is welded on control panel.

The pairing network socket at 1-250 to choosing.

The pairing the loop line frame at 1-250 to choosing.

Because the utility model is to be fixed with the network socket of pairing, the loop line frame of pairing at a holder upper surface, display is arranged on the holder, control panel is fixed in the holder, the network socket of pairing, the loop line frame of pairing are connected in series by grid line and display device, insert grid line two in the network socket respectively or be connected on loop line frame upper and lower two and arrange corresponding wire clamp position, if when grid line one end did not have crimping good, pilot lamp did not work.If during the upper-lower position dislocation, the control circuit of another termination of LED becomes and can find where misalignment position is by to every control connection of one group of LED.The network socket of pairing, the loop line frame of pairing can allow a plurality of experimental implementation persons carry out simultaneously at 1-250 to choosing like this, and not only intuitive is good, price is low, satisfies a plurality of experimenters' demand simultaneously.

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:

Description of drawings: Fig. 1 is an embodiment surface structure synoptic diagram;

Fig. 2 is the control panel circuit diagram.

Among the figure, 1, the pairing network socket; 2, holder; 3, control panel; 4, display; 5,8 spider lines lead-in wire; 6, gauge tap circuit; 7, Pei Dui loop line frame.

Embodiment: as shown in Figure 1, on holder 2, be fixed with the network socket 1 of pairing, loop line frame 7, the display 4 of pairing, display 4 is made up of two groups 16 LED, 16 LED is divided into up and down each 8, and the loop line frame 7 of network socket 1, pairing, display 4 are connected by the grid line control panel 3 interior with being fixed on holder 2.

Concrete work and experiment method are as shown in Figure 2, after the grid line connection of the loop line frame 7 of the network socket 1 that matches, pairing by different numberings and color, every grid line two ends all are in series with a LED, and the LED of upper end is added on the power supply of 5V after by current-limiting resistance; The LED negative terminal of lower end connects gauge tap circuit 6, when gauge tap circuit 6 is connected each one by one, as long as each root grid line all press reference numeral and is connected with color, fixing display 4 on the holder 2 at this moment, just about the LED of correspondence bright entirely.If grid line has one not connect, because LED is a series relationship up and down, the LED up and down of corresponding position can be not bright.Connect as a grid line dislocation, when gauge tap circuit 6 was connected each one by one, the LED of corresponding wrong position was bright.In Fig. 2, the numbering of grid line is all numbered from 1 to 8, and corresponding have demonstration at holder 2.

Holder 2 of the present utility model can be made experiment table, also can make casing.
