A circuit board is arranged in the fixing seat, and every one of the paired network connection seats is connected with the display circuit through the circuit board. The computer network experimental compression bonded line facility has the advantage of low cost, simultaneously, satisfying many people to carry out connection experiment, test and exam in the aspect of computer and communication network for many times.
Description
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 computer network crimping experimental provision that operation training is used.
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 that 0.5 millimeter lead is formed by 8 core diameters, and 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 the professional and use, it is too big to offer this type of experimental expenses, and experiment can't be offered.
Summary of the invention: the purpose of this utility model provides a kind of Computer Network Experiment crimping line apparatus, and its expense is low, can satisfy wiring experiment, test and examination that many people repeatedly carry out computing machine and communication network aspect simultaneously.
The purpose of this utility model is achieved in that computer network crimping line experimental provision, it is made up of network connection seat, holder, the display circuit of pairing, it is characterized in that: the network connection seat of pairing is installed on the holder surface, display circuit is installed on the holder, and circuit board is in holder.The network connection seat of pairing is connected with display circuit by circuit board.
Described display circuit is to be connected to form by LED and circuit board, and each lead in the grid line is connected in series one group of LED at least, the corresponding core network conductors of each group LED.
The pairing the network connection seat can 1-500 between choose.
Principle of work of the present invention is: with grid line strip off on request, two is crimped on the corresponding wire clamp position of upper and lower two rows of network connection seat respectively, according to line preface, colour of solution correct after, with Crimping Pliers crimping one by one.When two rows correspondence position line ball was correct, the corresponding lamp of LED up and down was simultaneously bright.If when an end did not have crimping good, pilot lamp did not all work.If during the upper-lower position dislocation, the pilot lamp of correspondence position is bright.
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 display circuit figure.
Among the figure, 1, network connection socket or 110 loop line framves; 2, holder; 3, terminal block; 4, light-emitting diode display; 5, network lead-in wire; 6, circuit board.
Embodiment: as shown in Figure 1, by the network connection socket or the 110 loop line framves 1 that are installed in above the holder 2, light-emitting diode display 4 and the terminal block 3 that is installed in holder 2 inside connect network lead-in wire 5 and form the Computer Network Experiment devices.
As shown in Figure 2, network connection socket or corresponding 1 the LED lamp of 110 loop line framves, 1 each connection jaws.Between every pack module, be in series with LED, resistance, on resistance and LED lamp, DC voltage arranged.The network connection seat 1 of pairing is installed on holder 2 surfaces, on the holder 2 display circuit is installed, and circuit board 6 is in holder.The network connection seat 1 of pairing is connected with display circuit by circuit board 6.During experiment, when two position line balls were correct about every pack module of network connection socket or 110 loop line framves 1, the corresponding lamp of LED up and down was bright.If single line crimping dislocation, the pilot lamp of corresponding dislocation is bright.
Holder 2 of the present utility model can be made experiment table, also can make casing or frame.
Use the utility model to offer the Computer Network Experiment class, can allow a plurality of experimental implementation persons carry out the crimping line experiment of network and communication aspect simultaneously, not only intuitive is good, high conformity but also price are low.For carrying out the Computer Network Experiment class, colleges and universities provide the equipment of being badly in need of.Improve students'ability for practice.
