Description

A kind of Network plug that meets six class standard

Technical field

The utility model relates to the parts of transmission system, in particular for connecting a kind of Network plug that meets six class standard of computer network and terminal thereof.

Background technology

Network is with independent microcomputer or terminal, utilizes transmission medium to be connected with each other, and follows certain agreement, carries out information exchange, realizes resource-sharing.

In order to improve the communication network transmission speed, (the Telecommunications Industries Association of Telecommunications Industries Association, TIA) on the basis of the 5th class (Category5) comprehensive wiring standard, develop and the 6th class (Category 6) comprehensive wiring standard, the transmission rate of the 6th class has been brought up to 200MHz by the 100MHz of the 5th class; In addition, six class standard will have more 25% at least than the 5th class standard on performance requirement.Therefore, for the test frequency of the 6th class performance, reach 250MHz.The difference of the 6th class and the 5th class standard maximum is to improve the performance of loss aspect of crosstalking and reflux.

Transmission medium commonly used is made up of the netting twine and the RJ45 connector of certain-length.

Wherein Chang Yong netting twine has twisted-pair feeder, coaxial cable, optical fiber etc.Twisted-pair feeder can be divided into Shielded Twisted Pair (STP) and unshielded twisted pair (UTP) by its screen whether the added metal twine overlaps.

The transmission medium of Ethernet mainly is the twisted-pair feeder that meets EIA/TIA-568 standard at present.The original design purpose of twisted-pair feeder is exactly for reducing interference such as noise, cross-talk, because the electric current on lead can generate an electromagnetic field when flowing, eight electronics lines can produce 8 electromagnetic fields, the mutual interference of 8 electromagnetic field phases, can influence transmission performance, so positive signal line and negative signal line pair twist, the electromagnetic field that both are produced mutually offsets, just can reduce to disturb.Electronics line by 8 different colours is divided into 4 strands together, and the effect of twisting is the influence that reduces electromagnetic radiation and external electromagnetic interference as far as possible in pairs.

Referring to Fig. 1～Fig. 3, the structure of existing RJ45 connector is: comprise that plug is moulded shell 1a, its latter half is hollow structure 100a, is used to insert netting twine 3a, claims that usually this hole is a through wires hole; Leading section 11a has eight groove 111a, and is connected with hollow structure 100a; Plug moulds that shell 1a top is oblique backward to be extended with an elastic fastening plate 12a, is handle portion, and handle each side has a step, is used for plug is fixed in the socket with matching, and promptly only when handle is depressed, plug could be extracted from socket; 8 connect contacts, are inserted in eight groove 111a of leading section 11a, mould the stereotyped writing netting twine 3a of shell 1a hollow structure 100a and are connected with inserting plug respectively, form signalling channel.

But in above-mentioned the 5th traditional class plug, 8 connect contacts at sustained height, its with four to (eight) electronics line all be sustained height be connected the contact connection, the value of the cross-talk of this structure and backflow loss is higher, is difficult to reach six class standard.

Summary of the invention

For reaching above-mentioned purpose, the technical solution of the utility model is:

A kind of Network plug that meets six class standard, it comprises, insulating body, it has a hollow cavity, and leading section also lists the groove that has for plant usefulness, and this groove is connected with hollow cavity; Eight connect contact, are inserted in the groove of described insulating body respectively, and the lower end that connects contact electrically connects mutually with the netting twine that inserts the insulating body hollow cavity; Comprise two long connection contacts, six short contacts that connect in eight connection contacts; Two long connection contacts evenly are arranged at intervals at these six short connections in the contact.

Further, described insulating body hollow cavity diapire is planted for these two long connection contacts to having two grooves by two long connection contacts.

In addition, the Network plug another one version that meets six class standard of the present utility model, it comprises, insulating body, it has a hollow cavity, and leading section also lists the groove that has for plant usefulness, and this groove is connected with hollow cavity; Eight connect contact, are inserted in the groove of described insulating body respectively, and the lower end that connects contact electrically connects mutually with the netting twine that inserts the insulating body cavity; Comprise two long connection contacts, six short contacts that connect in eight connection contacts; Two long connection contacts evenly are arranged at intervals at these six short connections in the contact;

This Network plug also comprises, a netting twine support, its upper edge axially parallel are arranged with the groove of planting for netting twine, and the groove diapire of wherein corresponding described two long connection contacts is lower than other grooves, is connected the contact bottom with length and is complementary; Netting twine support behind the plant netting twine inserts the insulating body cavity, and eight connect the lower end of contacts and electrically connect mutually with netting twine on the insertion insulating body cavity netting twine support.

The beneficial effects of the utility model are:

The utility model connects contact by length and is provided with at interval, and when plug was connected with communication cable, eight connected contact and arrange highly with eight electronics lines in the communication cable two respectively and be connected, and have reduced cross-talk and backflow loss value, thereby have reached six class transmission performances.
