The first shield opening 651 crossed；The secondary shielding hole 652 for accommodating shield terminal 52 and passing through is equipped with the side of the second through hole 632；
The side of third through-hole 633, which is equipped with, accommodates the 3rd shield opening 653 that shield terminal 53 passes through；Set in the side of fourth hole 634
Have and accommodate the 4th shield opening 654 that shield terminal 54 passes through.
Since the first insulating trip 21, the second insulating trip 22 and 23 structure of the 3rd insulating trip are identical, their effect is to adopt
The relative position of metal terminal is fixed with integrally formed technique, therefore detailed Jie only is done to the first insulating trip 21 hereinafter
Continue.First insulating trip 21 is flake, has the first side 211 and second side 212 being oppositely arranged, and lower edge
214 and leading edge 215.Prolong from leading edge 215 docking section 312,322,332,342 of first group of signal terminal 31,32,33,34
Stretching out the first insulating trip 21, the first insulating trip 21 extends from lower edge 214 in pin portion 311,321,331,341, pars intermedia 314,
324,334,344 are embedded in still local among the first insulating trip 21 expose in air.
Preferably, the both sides insulating materials of the pars intermedia 314,324,334,344 of first group of signal terminal 31,32,33,34
Excavated by local to form some grooves 204, i.e. in being corresponded in the first side 211 and second side 212 of the first insulating trip 21
Between the position in portion 314,324,334,344 be respectively equipped with some grooves 204, and then reduce first group of signal end being disposed adjacent
The thickness of insulating materials between son 31 and second group of signal terminal 42, since the width of those widened sections 315,325,335,345 will
More than the other parts of pars intermedia 314,324,334,344, therefore the groove most in those widened sections 315,325,335,345
204 are partially exposed to those widened sections 315,325,335,345 in air, and because those widened sections 315,325,335,345
Length gradually shortens, therefore the area of exposure is also gradually reduced.Thereby reach adjustment electric connector 100 in differential signal it
Between crosstalk and impedance matching purpose.
Meanwhile first is additionally provided with some sleeve configuration straight slots through first side 211 and second side 212 on insulating trip 21
203, the straight slot 203 is set parallel to groove 204.On the length direction parallel to first group of signal terminal 31, adjacent two
Reinforcing portion 2031 is equipped between a straight slot 203.Straight slot 203 can save material and be conducive to dissipating inside electric connector 100
Heat.In order to meet the requirement of moulding process, pars intermedia of first insulating trip 21 in first group of signal terminal 31,32,33,34
The mounting hole 202 for exposing first group of signal terminal 31,32,33,34 is locally equipped with 314,324,334,344 position, Gu
When to determine hole 202 be due to that the pillar (not shown) in molding die grips metal terminal, the insulating materials of fusing
Pillar can not be filled into and be formed, the reinforcing portion 2031 is with 202 position of mounting hole mutually along first group of signal terminal 31
Length direction on stagger so that the maximum intensity of the first insulating trip 21.Further, first insulating trip 21 also exists
Lower edge 214 is corresponded to equipped with some the lower edge groove 2140 in anteroposterior direction across each metal terminal, the lower edge grooves 2140 respectively
It is arranged near the pin portion 311,321,331,341 of first group of signal terminal 31,32,33,34, and lower edge groove 2140 is first
The both sides of group signal terminal 31,32,33,34 extend transversely through the first insulating trip 21 and are equipped with lower marginal pore 201 respectively.Preferably, lower edge
The area of groove 2140 is gradually shortening and broaden with metal terminal.
It is not difficult to draw, the utility model reduces metal end to the greatest extent to realize that the transmission performance of electric connector 100 maximizes
The isolation material on sub- periphery, however, to ensure that the firmness of metal terminal, the those widened sections 315,325,335,345 is opposite
Widen, and then increase insulating materials cladding area.
On the other hand, docking section 312,322,332,342 from leading edge 215 extend the first insulating trip 21 after in hanging
State, after being the frequent grafting of butt connector, easily opens deformation, in order to reinforce docking section 312,322,332,342, and it is described
First insulating trip 21 local extend forward along metal terminal on the basis of leading edge 215 is equipped with strengthening portion 213.Amplified reinforcement
Portion 213 is as shown in Figure 14 and Figure 17, and docking section 312 and docking section 322 are fixed as one group by strengthening portion 213 respectively, by docking section
332 and docking section 342 be fixed as one group, due to the effect of strengthening portion 213 be strengthen docking section 312,322,332,342 root
Portion prevents metal terminal from deforming, and in order to reduce the insulating materials on metal terminal periphery, is set between strengthening portion 213 and leading edge 215
There is waist 2130, the both sides of the waist 2130 are respectively by pars intermedia 314,324, the Yi Ji of first group of signal terminal 31,32
The part of pars intermedia 334,344 of one group of signal terminal 33,34, which is exposed, facilitates injection mold to be clamped in forming plastic cement
Each metal terminal, while the front end of strengthening portion 213 coats each pair of metal terminal along in the circumferential direction of metal terminal completely.In addition,
Increase to solve the material caused by the offset that offset portion 310,320,330,340 brings docking section 312,322,332,342
Thick problem, the opposite direction in offset direction is equipped with strengthening portion 213 and is equipped with step successively, i.e., in first group of signal terminal 31
Docking section 312 is equipped with first step 2131, and second step 2132 is equipped with docking section 322, and the is equipped with docking section 332
Three steps 2133, and the 4th step 2134 is equipped with docking section 342.The first step 2131, second step 2132,
Three steps 2133 and the 4th step 2134 do not reduce material on docking section 312,322,332,342 Impact direction, therefore
Reduce the cross-interference issue between adjacent metal terminal pair again while ensure that metal terminal root intensity and save material
Material.
As shown in Figure 19 to Figure 21, setting is mutually drawn close in docking section 312,322 in front end, after butt connector insertion,
312,322 stress of docking section is opened towards above-below direction, and foregoing strengthening portion 213 sets to strengthen the strength of metal terminal root
Put, in the embodiment of the utility model, each metal terminal extends forward from storage space 601 respectively, each by terminal groove
Enter after 6350 in docking groove, rake 630 is equipped with the roof of terminal groove 6350, rake 630 is leaned on towards docking section 312
Hold together direction inclination, open amplitude to achieve the purpose that to limit docking section 312, prevent the docking section 312 of metal terminal improper
Transition deformation when insertion, meanwhile, the rake 603 is tilted with the inclination of docking section 312 so that is extended beyond and is added
The top gap of the metal terminal in strong portion 213 is consistent size as far as possible, avoids the fluctuation for causing impedance, is conducive to high frequency letter
Number stablize transmission.Similarly, the top of docking section 332, the lower section of docking section 322,342 terminal groove 6350 in also be provided with
Towards the inclined rake of metal terminal wrap direction (not shown), and then realize from each docking section 312,322 of comprehensive limitation,
332,342 scope of activities, meanwhile, pair of second group of signal terminal 41,42,43,44 and shield terminal 51,52,53,54
Rake (not shown) is again provided with socket part, prevents each metal terminal from deforming, and then improve the plug longevity of electric connector 100
The stability of life and signal transmission.
