Description

The Improvement type connector

A kind of Improvement type connector refers to a kind of serial port connector that applies to 1394 forms, 6 pins especially.

The Improvement type connector belongs to electricity essential electronic element field line connector class.

When the computer peripheral product facility is connected with host computer in recent years, the signal connector becomes important step, problem such as loose contact and Electromagnetic Interference, can influence the correctness of signal transmission, in the general connection cable of 1394 forms, 6 pins (pins) of prior art, the connector major defect is not meet the environmental protection notion, do not meet the requirement that the people pacifies the thing peace yet, yielding during production costs, electromagnetic interference is easily arranged, this splicing ear (Fig. 1) comprises the iron-clad C of two combinations up and down, one joint A is housed among the iron-clad C to be connected in a cable B and to place iron-clad C, earlier a joint A is welded mutually with the electric wire of cable B during assembling, be placed on again among a slice iron-clad C of iron-clad C up and down, after engaging again with another sheet iron-clad C mutually pressing form, wherein the tail end of a slice of iron-clad C is designed to a pattern that holding ring D arranged, in order to be connected more firm with iron-clad C cable B, its shortcoming is an iron-clad C Combination Welding face more (four of iron-clad 3 sides up and down) up and down, waste man-hour, easily cause signal to disturb, easily wash out during injection moulding, easily make the welding of cable and joint destroyed.

The purpose of this utility model is: material and cost when reducing the connector manufacturing, avoid electromagnetic interference, and cover entirely, ensure personage's safety.

The purpose of this utility model can realize by following measure, connector comprise front tab part, shell, integrated single form iron-clad, transmission yarn, anti-short circuit drag sheet, be located at the oval stretching pipe of the rear end after the iron-clad pressing and be located at joint and a plurality of terminals compositions of the end of a thread of cable between partly; Of the present utility modelly can also realize that front end is pointed in a plurality of terminals by following measure, the leading portion part also is provided with a convex and can snaps in joint; Its back segment of a plurality of terminals partly is provided with the double fastener button, and the back segment part also is provided with the double wedge that props up joint; Oval stretching pipe is the structure of cup back pipe before the overcoat iron-clad; In the end of a thread braiding of cable, comprise being provided with a plurality of bilateral folders that contain pricker; The side of connector is provided with draw-in groove, and the side of iron-clad is provided with trip, and trip matches with draw-in groove and engages; Iron-clad forms an injecting hole and a pressure compensation opening after pressing, the iron-clad face is provided with salient point; Combination has the shell with iron-clad, joint and cable cladding, and the upper and lower faces middle body of shell is square concavity down; Oval stretching pipe rear end can further press from both sides riveting and become ellipticity, makes two ends flat logical and clamp cable with the braiding folder, the iron-clad 360 degree boxing before it after cup end and the pressing.

The utility model has the advantages that: good looking appearance, minimizing are made man-hour, improve output, are covered, avoid electromagnetic interference entirely, and the tool environment-friendly function satisfies personage's safety requirements.
