Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically technical scheme of the present invention.In specification, same or analogous drawing reference numeral is indicated same or analogous parts.Following explanation to embodiment of the present invention is intended to present general inventive concept of the present invention is made an explanation with reference to accompanying drawing, and is not to be understood that to a kind of restriction of the present invention.
As shown in Figure 3, connector 200 of the present invention comprises: an insulation core body 1 has relative a stiff end 11 and an inserted terminal 12; Be fixed on a plurality of signal terminals on the said insulation core body 1 to 2, each signal terminal all extends to said inserted terminal 12 from said stiff end 11 to each signal terminal 21 in 2; Be fixed on a plurality of earth terminals 3 on the said insulation core body 1; Each earth terminal 3 all extends to said inserted terminal 12 from said stiff end 11; Wherein: at said stiff end 11; Said a plurality of earth terminal 3 is placed at first row of first height, and said a plurality of signal terminals are placed at second row of second height in 2 at least one pair of, and the remaining signal terminal of said a plurality of signal terminal centerings is opposite to the 3rd row at the 3rd height.It should be noted that Fig. 3-7 only is that schematically the arrangement of signal terminal and earth terminal is not limited thereto, its number also is not limited thereto.
Though in the accompanying drawing with formal description the present invention of DiiVA connector,, technical scheme of the present invention also can be applied to the connector of other type.
Preferably, shown in accompanying drawing 5, said second highly is higher than first height, and the said the 3rd highly is lower than said first height.Certainly, as long as signal terminal is opposite to two rows of differing heights, and earth terminal be in signal terminal to place height different height, the height relationships between first height here, second height and the 3rd height can change.For example, earth terminal can not be place signal terminal to the place two row between, but place this two row on or under.
Shown in the right figure of Fig. 3, earth terminal 3 is arranged in first row, and for example signal terminal is arranged in second row to the signal terminal of B to 2, and for example signal terminal is arranged in the 3rd row to the signal terminal of C to 2.Like this; Guaranteed that difference signal terminal is not to existing the difference on the height at stiff end 11; And the signal terminal each signal terminal centering is under the situation of identical height at said inserted terminal 12; Especially can strengthen difference signal terminal between coupling, reduce the interference right to the adjacent differential signal terminal.
In addition; Because signal terminal 21 and earth terminal 3 are arranged in two rows from prior art become and be arranged to three rows; So increased the level interval between the signal terminal; Thereby can increase the scope of application of wire rod, for example can use the wire rod in big line footpath, this helps to increase the welding efficiency of wire rod.
Advantageously, the distance between the distance on the short transverse and said the 3rd row and first arrange is identical between said second row and said first row.
Like Fig. 3, shown in the 5-7, the signal terminal that is arranged in second row to 2 be arranged in the 3rd signal terminal arranged to 2 on the short transverse to and between stagger each other.More advantageously, a plurality of signal terminals that are arranged in second row and the 3rd row pursue over the ground in second row and the 3rd row's arranged alternate 2.Thereby such layout is particularly advantageous in and increases signal terminal and can use the wire rod in big line footpath to the spacing between 2, and further reduced differential signal between interference.
Like Fig. 3, shown in 4; The said a plurality of earth terminals 3 that are in first row all are electrically connected with a sheet earth terminal 4 that is in first row; Though only show an earth terminal among Fig. 4,, in fact can there be a plurality of other earth terminals to be electrically connected on this sheet earth terminal 4.Like this, sheet earth terminal 4 is formed between second row and the 3rd row, and this can play the effect that strengthens shielding.In addition, can also be increased in the bonding area of stiff end and earth terminal 3 like this, improve welding efficiency.Alternatively, though do not illustrate, the said a plurality of earth terminals that are in first row can be integrally formed as a sheet earth terminal 4.
Shown in Fig. 3-7, said insulation core body 1 also comprises the body 13 between said stiff end 11 and said inserted terminal 12.Said stiff end 11 comprises: parallel relative, perpendicular to first plane and second plane of this short transverse; And from least one boss 14 on said second plane of said body 13 extend throughs; Wherein: the signal terminal that places second row is to being positioned on first plane; The sheet earth terminal 4 that places first row is on this second surface and between second surface and said at least one boss 14, place the 3rd signal terminal arranged to 2 each to be positioned at boss 14, parallel with said second surface and not with said second surface facing surfaces on.The number of boss 14 can be one, and only the part of sheet earth terminal 4 is covered by a said boss 14 simultaneously, and like this, the part of the sheet earth terminal of vacating 4 can be used as welding portion.Perhaps the number of boss 14 equals 2 at least; And only the part of sheet earth terminal 4 is covered (like this by all boss; The part of the sheet earth terminal of vacating 4 can be used as welding portion), place the 3rd row signal terminal to 2 be arranged in said at least one boss corresponding boss, parallel with said second surface and not with said second surface facing surfaces on.
Likewise; The signal terminal that is arranged in second row's (first surface) to 2 be arranged in the 3rd arrange (the said surface of boss 14) signal terminal to 2 on the short transverse to and between stagger each other; More advantageously, a plurality of signal terminals that are arranged in second row's (first surface) and the 3rd row (the said surface of boss 14) pursue over the ground in second row's (first surface) and the 3rd row's (the said surface of boss 14) arranged alternate 2.Shown in Fig. 3-7, advantageously, with row's signal terminal to the distance between 2 corresponding to a distance that signal terminal is shared to 2 layout.
Though do not illustrate; Said stiff end 11 can comprise parallel relative, perpendicular to first plane and second plane of this short transverse; Wherein, Place second row's signal terminal to be positioned on first plane, place the 3rd row's signal terminal to be positioned on second plane, and place first row's said sheet earth terminal 4 to be arranged between this first plane and second plane 2 to 2.
In addition, each signal terminal 21 be positioned at or place also comprise on the surface signal terminal 21 only a part be embedded into this surface, and signal terminal 21 is embedded in this surface and with the situation of flush, shown in the accompanying drawing 3-7 for example of the present invention.
Utilize technical scheme of the present invention, can obtain one of following technique effect at least: guarantee that differential signal is consistent to the path, reduce differential signal between cross-talk; Improve the possibility of the wire rod that uses big line footpath, thereby improved the welding efficiency of wire rod, taken into account feasibility and the convenience produced.
Although illustrated and described embodiments of the invention; For those of ordinary skill in the art; Be appreciated that under the situation that does not break away from principle of the present invention and spirit and can change that scope of the present invention is limited accompanying claims and equivalent thereof to these embodiment.It should be noted that word " comprises " does not get rid of other element or step, and word " " or " one " do not get rid of a plurality of.In addition, any element numbers of claim should not be construed as restriction scope of the present invention.
