Abstract

The utility model relates to a network plug. The upper part of a housing of the plug is slantwise extended with an elastic handle towards the rear side and the upper side; the left side and the right side of the handle are respectively provided with a step; the front end of the plug is provided with a lug boss; the middle part under the plug is provided with a long groove and a ladder groove, and the left lower part of the plug is provided with a press wire mechanism; the front end of the housing of the plug is provided with eight grooves for inserting and fixing connecting contact sheets which are inserted into the housing of the plug from the grooves and are respectively connected with eight strands of transmission media in small wire holes, and threading holes are arranged on the part of a middle layer of the plug. When wire conducting bodies in the threading holes respectively pass through the small wire holes, the wire conducting bodies are connected with contact points of the contact sheets to form a signal path. After a connecting point of a handle and the housing of the plug uses circular arc transition, stress is reduced and service life is prolonged. Process grooves on both sides of the combined points of the threading holes and the small wire holes make the wall thickness uniform, and burst can be prevented when injection molding is conducted.

Description

Network plug

Technical field

The utility model relates to the parts of transmission system, is a kind of Network plug that is used to connect the network and the network terminal, in particular for connecting a kind of Network plug 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.Transmission medium commonly used is made up of the netting twine and RJ 45 plugs 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.Twisted-pair feeder is divided into 4 strands together by the electronics line of 8 different colours, and the effect of twisting is the influence that reduces electromagnetic radiation and external electromagnetic interference as far as possible in pairs.At EIA (Electronic IndustriesAssociation, EIA)/TIA (Telecommunications IndustriesAssociation, Telecommunications Industries Association)-568 in the standard, twisted-pair feeder is divided into by electrical characteristic: three classes, four classes, five classes, six class lines.The most frequently used in the network is three class lines, category-5 cable and six class lines.Ready-made netting twine will insert RJ 45 plugs in RJ 45 sockets of the network interface card or the network equipment.Correspondingly RJ 45 plugs, socket also can be divided three classes, five classes or six class electrical characteristics.RJ 45 plugs are made of metal contact and plastics, and making the needed RJ 45 quartzy joint front ends of netting twine has 8 grooves that are used to imbed the metal contact, is called for short " 8P " (Position, position).Hard contact in the groove has 8, be called for short " 8C " (Contact, contact), so industry has the another name of " 8P8C " to this.After netting twine connects, for protection netting twine (transmission medium) and the fastness that guarantees that netting twine (transmission medium) is connected with plug, usually at plug and netting twine junction injection moulding sheath.

The structure of RJ45 connector is in elder generation's technology: it is hollow structure that plug is moulded the shell latter half, is used to penetrate netting twine, claims that usually this hole is a through wires hole; The through wires hole front end is eight separate little line holes, is used for inserting the stereotyped writing electronics line of transmission medium; Shell upper backward and obliquely upward be extended with an elastic fastening plate 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; Plug below mid portion is a ladder-type trough and an elongate slots, plays positioning action when inserting the connection contact; The lower left is a thread depressing mechanism, after plug and netting twine connect, when this mechanism is connected with the electronics line at the metal contact, push down the netting twine in the plug through wires hole, play the fixedly effect of netting twine, when plug plugs, can not cause the metal contact to be connected loosening with the electronics line even come off; RJ45 connector shell front end has eight grooves, is used for riveting and goes into and the fixing metal contact, and the riveting from these grooves of metal contact is gone in the plug body, is connected with the stereotyped writing electronics line of lead-in wire in the groove respectively, thereby has formed a signalling channel.

Formerly the position that is connected with quartzy plug body of its handle of the RJ45 connector in the technology is a quadrilateral structure, two plane parallel up and down, and when plug and socket plug, this position stress is concentrated, frangibility, thus influenced useful life of whole quartzy plug; RJ45 connector through wires hole and both sides, junction, little line hole are entity structure, and wall unevenness is even, and when the injection moulding sheath, this position easily produces the explosion phenomenon under high pressure and action of high temperature.

Summary of the invention

For overcoming the defective that above-mentioned technology formerly exists, through wires hole and both sides, little line hole were difficult for the Network plug of explosion when the utility model provided a kind of useful life that has increased handle and plug and injection moulding sheath.

Concrete structure of the present utility model is: there is through wires hole the middle part, is used to penetrate transmission medium; The through wires hole front end is eight separate little line holes, is used for inserting respectively the stereotyped writing electronics line of transmission medium; Through wires hole is connected both sides with little line hole and respectively opens a technology groove; Shell upper backward and obliquely upward be extended with a resilient handle, handle each side has a step, is used for plug is fixed in the socket with matching; Handle and plug body junction have the circular arc concave surface; Plug below mid portion is an elongate slots and a ladder-type trough, plays positioning action when inserting the connection contact; The lower left is a thread depressing mechanism, and this mechanism is directly used in the transmission medium of pushing down in the plug lead-in wire groove, plays the effect of constant transmissions medium; The plug body front end has eight grooves, is used for riveting and goes into and fixedly connected contact, connects contact riveting from these grooves and goes in the plug body, is connected with stereotyped writing transmission medium in eight little line holes respectively, thereby has formed a signalling channel.

The beneficial effects of the utility model are: the plug handle adopts arc transition to be connected with the plug casing junction, has avoided too much edges and corners, plays the effect that reduces stress when bending, thereby makes increase by 30～50% than originally the useful life of handle. A technology groove is respectively opened in the both sides of through wires hole and junction, little line hole, makes this position wall thickness even, when the injection moulding sheath, can play the effect that prevents explosion.
