Description
Technical field:
The utility model relates to high-definition digital interfacing field, refers in particular to a kind of combination plug of high-definition digital interface.
Background technology:
High-definition digital interface such as HDMI, Displayport can provide the data transfer bandwidth up to 10Gbps, and can guarantee that high-quality video-audio signal transmits.Therefore, the requirement of the high frequency characteristics of high-definition digital interface (as characteristic impedance, cross-talk, decay, delay difference etc.) is all very high, this just requires to destroy as few as possible the structure of former wire rod in the course of processing, to be changed with guaranteeing the high frequency characteristics minimum degree.The structure of HDMI, the former wire rod of Displayport generally is made up of holding wire and one group of electronics line many, and wherein holding wire is made of a pair of heart yearn and a ground wire.At present, generally be after the heart yearn of former wire rod is broken, by one or more winding displacement plugs each heart yearn is fixed earlier, be welded in again on the terminal of connector, but because the design of winding displacement plug is not good enough, destroyed the structure of holding wire in the processing largely, intersected serious between the heart yearn, make the high-frequency signal on the heart yearn interfere with each other, thereby had a strong impact on signal transmission quality even made loss of data.
In addition, because digital interface can produce a large amount of heats when welding, and ground wire conducts heat comparatively fast, and at present because the design of winding displacement plug is unreasonable, ground wire can't in time spread out of heat, usually causes the insulation of heart yearn in the holding wire to be scalded, and causes that short circuit and other are electrically bad.
Also there is following defective in present digital interface owing to its structural design is unreasonable: in order to prevent the short circuit of ground wire and signal transmission twisted pair wire, generally can put a heat-shrinkable T bush to ground wire earlier, put a heat-shrinkable T bush for again holding wire integral body, so both increase man-hour, also increased material cost.This is a deficiency in the present high-definition digital interface processing.
The utility model content:
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of combination plug of high-definition digital interface, this kind combination plug is few to the structural damage of former wire rod, guaranteed that the high-definition digital interface has good high frequency characteristics, in addition, ground wire can in time conduct heat during welding, be difficult for scalding the insulation of heart yearn, and need not overlap heat-shrinkable T bush, the electrical yield that has improved product has reduced production cost simultaneously.
For achieving the above object, the utility model is achieved through the following technical solutions: the combination plug comprises winding displacement plug and separated time plug, winding displacement plug and separated time plug snapping, two surfaces up and down of described winding displacement plug form wire casing respectively, it is characterized in that: two surfaces up and down of described separated time plug separate through dividing plate respectively and form at least two big wire casings, be used to place the lip-deep dividing plate of big wire casing correspondence its another of holding wire on the surface of separated time plug, the dividing plate middle part is emptied and is the dividing plate cavity; Form on the mating surface of winding displacement plug and separated time plug with the separated time plug on dividing plate cavity tension disc one to one, when separated time plug and winding displacement plug fastened, each tension disc was inserted into respectively in the dividing plate cavity corresponding with it.
Two surfaces up and down of described separated time plug mold three big wire casings respectively, and the wire casing of respective number is corresponding on the terminal notch of big wire casing and the winding displacement plug.
Two surfaces up and down of described separated time plug mold big wire casing and little wire casing respectively.
The longitudinal cross-section of the inner end of described dividing plate cavity is stairstepping.
The longitudinal cross-section of the end of described tension disc is the stairstepping with the inner end form fit of dividing plate cavity.
The front end of described tension disc forms groove, and one of the common formation of this groove and dividing plate cavity inner end arc-shaped curved surface supplies ground wire to pass the ground through hole.
One side of the big wire casing on the corresponding separated time plug of described tension disc molds the small baffle of protrusion, and a side of the dividing plate of the corresponding separated time plug of tension disc then molds groove.
Beneficial effect: two surfaces up and down of separated time plug of the present utility model separate through dividing plate respectively and form at least two big wire casings, be used to place the lip-deep dividing plate of big wire casing correspondence its another of holding wire on the surface of separated time plug, when separated time plug and winding displacement plug fasten, the tension disc corresponding with each dividing plate cavity is inserted into respectively in the dividing plate cavity corresponding with it on the winding displacement plug, the utility model passes through simply and cleverly structural design, drop to minimum with making up the destruction of plug to former wire rod structure, can avoid the intersection of heart yearn again, guarantee that the high-definition digital interface has good high frequency characteristics; In addition, because it is circuitous crooked in this combination plug to thread to the ground wire on separated time plug opposite, make ground wire and assembly adhesive be plugged with longer contact length, ground wire can in time conduct heat during welding, is difficult for scalding the insulation of twisted pair wire, improves the electrical yield of product, and ground wire and heart yearn separate, need not overlap heat-shrinkable T bush, reduce material cost, reduce machining period.
