The position of number terminal 31, therefore ensure that the high-frequency transmission rate of electric connector, and in the transmission for not influencing the electric connector 100
Good shield effectiveness is provided while rate.
4. being easy to control institute according to the actual situation since the abutment arms 413 tear molding from the masking shell 4
The length of abutment arms 413 is stated, to provide enough positive forces when abutment element insertion.
5. the abutment arms 413 are identical as masking 4 materials of shell, the abutment arms 413 have enough intensity, and described
Abutment element still is able to keep firm contact with the abutment element after repeatedly docking, and guarantees earth shield effect.
6. the difference signal terminal 31 and the abutment arms 413 are equipped in the opposite sides of the slot 14, into one
Step strengthens the effect of shielding again while improving transmission rate.
7. the abutting part 4132 for being located at 14 right side of slot connects with the described of 14 opposing left of slot is located at
The center symmetric setting of the relatively described slot 14 of contact portion 3121 is described right when guaranteeing that the abutment element is inserted into the slot 14
The two sides for connecing element can firm contact.
