Embodiment
Please refer to Fig. 1 to Fig. 4, the electric connector for socket that this creation suppresses to crosstalk can be fixed on the circuit board by welding manner, and includes: some insulating board bodies 10, some terminal group, some shielding sheet groups, a shell 40 and a back assembling cover 50.
Please with further reference to Fig. 5 and Fig. 6, respectively these some insulating board bodies 10 supervise each other system with mutually side by side mode arrange.Respectively be formed with some first binding members 12,13 on this insulating board body 10.In addition, respectively be formed with some assembling groves 100 on the side of this insulating board body 10.
Respectively this some terminal group system is separately positioned on respectively in this insulating board body 10, and respectively this terminal group includes some signal terminal 20s and earth terminal 20g.In addition, respectively this signal terminal 20s or earth terminal 20g system comprises a canned paragraph 21, an assembling section 22 and one electrical contact-segment 23.This canned paragraph 21 is to be embedded in this insulating board body 10 of correspondence.This assembling section 22 is to extend downwards from this canned paragraph 21, and for welding or crimping punching press and being fixed on the circuit board.This electrical contact-segment 23 is from canned paragraph 21 projection forward, can be forked.
Please arrive Fig. 9 with further reference to Fig. 7, these some shielding sheet groups mainly are be used to preventing crosstalking between the signal terminal 20s, respectively this shielding sheet group system is separately positioned on a side of these some insulating board bodies 10, respectively should shielding sheet group system constitute with some shielding sheets 30, and this shielding sheet 30 one of them is connected with earth terminal 20g in the corresponding terminal group at least, in addition, respectively some shielding sheets 30 of this shielding sheet group are to arrange and be not in contact with one another each other in the space mode.And respectively this shielding sheet 30 is to define some bending sections 305 that are enough to block the noise signal, and respectively is formed with some and the straight section 301,302,303 that respectively should bending section 305 spaces disposes on this shielding sheet 30, as shown in Figure 9.
According to antenna effect, the metal blocks of exposure has antenna characteristics easily, collect electric charge and its current potential is raise, and cause electric current, and electric current has the path of abundant length easily on the metal blocks and flees, and causes high frequency or low-frequency signal to disturb.Therefore, the shielding sheet 30 that these shielding sheet assembling and dismantling respectively is divided into some spaces can effectively reduce the respectively antenna effect of this shielding sheet 30.Specifically, respectively this shielding sheet 30 presents strip and makes to have and fill a part narrow width, and so the width of the single shielding sheet that this width combines in these some shielding sheets 30 less than a sizableness is but should shielding sheet 30 suppressing antenna effects.In addition, owing to respectively should shield sheet 30 along forming a plurality of bending sections 305 on the length, and because the straight section 301,302,303 between the two adjacent bending sections 305 can't link to each other in line each other, also constitute some path P 1, P2, P3 that can't link to each other in line on these straight sections 301,302,303, so being unfavorable for electric current flees, as shown in Figure 9, so the shielding sheet 30 of bending state can further be avoided antenna effect.
In addition, respectively respectively this shielding sheet 30 of this shielding sheet group is the interval 300 that forms the passage shape to each other.Moreover, respectively be formed with second binding member 32,33 that corresponding first binding member 12,13 of at least one and corresponding this insulating board body 10 combines on respectively this shielding sheet 30 of this shielding sheet group, this second binding member 32 also can contact earth terminal 20g in order to make shielding sheet 30 also as earthy, for example, second of Fig. 8 lower left corner combination unit 32,33 just contacts earth terminal 20g.In addition, respectively the shielding sheet 30 of this shielding sheet group is separately positioned in the assembling grove 100 of insulating board body 10 correspondences.
This shell 40 is to be covered in outside all insulating board bodies 10 with combined insulation plate body 10.In addition, these shell 40 front ends 41 are to run through the some interfaces 410 of formation to be arranged in the corresponding interface 410 to supply the electrical contact-segment 23 of terminal 20 respectively.
The assembling of this back is covered 50 and is incorporated into respectively these insulating board body 10 rear ends and can accurately makes up side by side in order to guarantee insulating board body 10.
Among this case preferred embodiment, respectively this first binding member 12,13 is groove or projection; Respectively this second binding member 32,33 is corresponding first binding member 12,13 projection or groove.
Among this case preferred embodiment, respectively this shielding sheet 30 that should be connected with this earth terminal is to form one first Connection Element 35, and this first Connection Element 35 can be a cramp; Respectively this earth terminal subsystem forms second Connection Element 25 that is connected with this first Connection Element 35, and this second Connection Element 25 can be a button hole that is interlocked with corresponding cramp.
Please with further reference to Figure 10, this creator tests for the signal of terminal 20, watch from interface 410 directions, it is that A is to I row and the 1st to 6 row that terminal 20 is compiled, at respectively this in twos adjacent terminal 20 carry out the cross-talk test, for example coordinate (A, 3) and two signal terminals of (B, 3) (being abbreviated as AB3 below the coordinate) are tested.Do not adopt shielding sheet group and adopt shielding sheet group test deck watch as follows:
Above-mentioned deck watch as can be known, most of signal terminal 20s after cooperating shielding sheet group, the cross-talk degree all has decline, and then the signal efficiency of transmission that can promote signal terminal 20s is with stable.
Please with further reference to Figure 11, among one embodiment of the invention, respectively this shielding sheet 30a is not connected with arbitrary signal terminal 20s or earth terminal 20g', so respectively this shielding sheet 30a does not have first Connection Element, and respectively this signal terminal 20s or earth terminal 20g' do not have second Connection Element.Yet respectively this shielding sheet 30a still has second binding member 32,33 with first binding member 12,13 in conjunction with insulating board body 10.In sum, only for the present invention's preferred embodiment, do not limit protection scope of the present invention with this, all equivalences of doing according to claim of the present invention and description change and modify, and are all within the scope that patent of the present invention contains.
