31 and main body 31 extend some connecting pins.From the foregoing it will be appreciated that in the present embodiment, the difference signal terminal is in first
Set in a row respectively in terminal group 20 and third terminal group 22.The main part 31 of the grounding assembly 3 is in along the lengthwise of insulating body 1
The sheet design of direction extension, and development length of the main part 31 along the longitudinally of insulating body 1 is not less than the difference
The arrangement total length of sub-signal terminal, so that the grounding assembly 3 can be by main part 31 in time by differential signal
Interference signal around terminal excludes, and ensures the stable transmission of high-frequency signal.
The leg 26 of the connecting pin and the ground terminal in first end subgroup 20 and third terminal group 22, which corresponds, to be set
Put.Specifically, the connecting pin includes and the leg 26 of ground terminal in first end subgroup 20 abuts against some first is connected
Some second connecting pins 33 that the leg of ground terminal abuts against in pin 32 and third terminal group 22.Second connecting pin 33
Extend towards with the leg 26 of ground terminal in third terminal group 22, and mutually supported in both free ends.Described
The leg 26 of two connecting pins 33 and ground terminal in third terminal group 22 is also located on same plane, to facilitate welding.
First connecting pin 32 is provided with the same plane with the leg 26 of ground terminal in first end subgroup 20
Weld part 321 and the elastic arm 322 extended forwardly to from weld part 321 in connectivity slot 18.The weld part 321 and first end subgroup
The leg 26 of ground terminal extends in the same direction in 20.The elastic arm 322 is formed with towards ground terminal in aforementioned first ends subgroup 20
Fixed part 24 direction projection abutting part 3221, the abutting part 3221 consolidates with ground terminal in aforementioned first ends subgroup 20
Determine portion 24 to abut against.
The main part 31 of grounding assembly 3 is arranged at the dead astern of Part I 1232 in the above embodiment of the present invention, and will
The first connecting pin 32 abutted with ground terminal in first end subgroup 20 is arranged to have the above-mentioned structure of elastic arm 322;Really, as
Another embodiment of the present invention, the main part 31 of grounding assembly 3 can be also arranged to the rear of the first wall 122, can in the case of this kind
The connecting pin abutted with the ground terminal in third terminal group 22 and first end subgroup 20 is replaced and designed, in a word, makes connecting pin
Welding position and ground terminal leg 26 it is in the same plane, you can reach the purpose of the present invention.
In summary, the present invention further sets some and terminal fixing grooves by the rear side of base portion 11 in insulating body 1
14 corresponding locating slots 171 so that the leg 26 of conducting terminal 2 is contained in locating slot 171 respectively, thus to conducting terminal
2 leg 26 is positioned, and prevents leg 26 from moving and the short circuit that contacts with each other;In addition, will be described to support in locating slot 171
The supporting surface 172 of leg 26 is arranged on same plane, thus may be such that the leg 26 after positioning is in the same plane, and then
Can effectively in management and control difference group conducting terminal 2 coplane degree, improve welding effect.Also, pass through the setting of grounding assembly 3, a side
Face can effectively shield external disturbance, improve stable signal transmission, on the other hand can reduce earth terminal by the setting of connecting pin
The setting of sub- rear connecting wire, another further aspect, the structure setting of the first connecting pin 32 of grounding assembly 3 can not only ensure to weld
Portion 321 and the coplane degree of leg 26, and the contact effect that can ensure with ground terminal is abutted using elastic arm 322.
