Be provided with a pair of of hook 521, with 113 location fit of a pair of of accepting hole that is arranged at the top of the first noumenon 11.Auxiliary section 52 is at it
Rear end has extended to form a pair of of elastic slice 522, and the elastic slice 522 is obliquely installed upwards, abuts shielding casing 4 with elasticity, reaches more
Good shield effectiveness.
Shown in referring to figure 3., in the second preferred embodiment of the present invention, in socket connector 100' in addition to earthing member 5
Other structures are identical as first preferred embodiment, and details are not described herein.The basic framework and first preferred embodiment of earthing member 5'
In earthing member 5 it is identical, difference is, the front and back end of the two sidewalls 512' of earthing member 5' is partly cut away to form one in front and back
It is located at the interconnecting piece 5121' at middle part upwards, so that side wall 512' is H-shaped, when earthing member 5' is inserted into the first noumenon along the longitudinal direction
11 and second on ontology 12 when, can suitably deform in a lateral direction, facilitate the insertion of earthing member 5', be brought just for assembling
Benefit.
It is arranged as shown in Figure 1, the shielding casing 4 is whole in ellipse tubulose, and is coated on terminal base 1 and earthing member 5
Periphery.The two sides of the shielding casing 4 have several installation feet 41 extended downwardly so that socket connector 100 to be fixed to
On circuit board.
It please refers to shown in Fig. 9 to Figure 10, in the third preferred embodiment of the present invention, the masking shell of socket connector 100 "
The size of body 4 " in the longitudinal direction can be set shorter, only cover the base portion of terminal base, can also such as of the invention first, the
Two embodiments are arranged longer like that, except the other structures and first preferred embodiment of earthing member 5 " are also identical, herein also no longer
It repeats.The basic framework of earthing member 5 " is identical as first preferred embodiment, and difference is, sets on the two sidewalls 512 " of earthing member 5 "
There is a pair of concave structure 5112 " being recessed towards metallic shield piece 3 ", this is oppositely arranged spill mechanism 5112 ", insulating body
13 " two sides are correspondingly arranged on matched holding tank 134 ", and concave structure 5112 " arches upward towards metallic shield piece recess,
When earthing member 5 " is inserted in terminal base can stretcher strain in a lateral direction, allow it to cross 3 " two sides of metal screen
Latch portion 32 ", after earthing member 5 " is assembled to outside the middle part of terminal base 1 " and insulating body 13 " forms, concave structure 5112 "
It accommodates and is limited in corresponding holding tank 134 ", prevent earthing member 5 " from moving along the longitudinal direction relative to terminal base.
To sum up, it on earthing member 5 of the invention, is set on any one group in one group of transverse wall 511 or one group of side wall 512
Set concave structure 5112 can be achieved earthing member 5 can cross directional stretch deformation with benefit assembling purpose.
