^3385 ι V. New description: ' 【New technology field】 This creation refers to the improved structure of the low crosstalk interference connector, which has protruding at the front end of the two side walls of the upper shell of the shielding shell. The grounding piece, and the upper wall surface of the upper casing also has a grounding piece for relatively improving the transmission impedance and stabilizing and improving the transmission quality, and the rear wall of the connecting H body has a retaining wall to prevent and avoid the cable. A situation in which a bare wire contacts the upper case to cause a short circuit. • [Prior Art] According to the prior art, the new patent No. M277168., in which the middle back side and the side of the bottom case of the shield case are provided with a grounding piece, but it still cannot fully meet the transmission specifications and cannot be mentioned (4) The transmission impedance is unstable compared to the transmission product f; furthermore, since the rear side of the left and right sides of the connector body is lower in contact with the rear side, it is not only resistant to EM [the effect has improved space, and the cable is The exposed wire portions of the human core wire are electrically connected to the piercing terminals, respectively, and when one of the bare wire portions is in contact with the two side walls of the upper casing of the metal shielding case, a short circuit occurs. This can cause the connector to be unusable, causing user confusion. The creator has the lack of pre-shipship townships and _, 阙 continuous research and improvement, and finally created and designed a low-crosstalk interference connection ^ improved structure. The main purpose of the present invention is to provide an improved structure of a low crosstalk interference connector, the side of the thief shell _ upper shell _ has no grounding strip protruding forward and the upper wall of the upper 29 is set. There is a grounding piece with a backward extension, which can be relatively increased by the grounding_domain reading and reading specifications.

The second purpose of the present invention is to provide an improved structure of a low crosstalk interference connector, in which the rear side walls behind the left and right sides of the connector body are each extended with a retaining wall to prevent electromagnetic interference ( The EMI) effect and the fact that the exposed wire (WIRE) portion of the cable (CABLE) is in contact with the two side walls of the metal upper case can cause a short circuit, thereby ensuring the function of the product. [New content] An improved structure of a low crosstalk interference connector comprises a connector body, a terminal transmission fixing seat, a terminal piercing seat, a circuit board, a movable cover, a shielding shell and the like, and is characterized in that: The side wall surfaces on both sides of the upper shell of the shielding shell each have a grounding piece protruding forward, and the upper wall surface of the upper shell is provided with a grounding piece having a rearward extending portion, which can relatively increase the grounding area and is more suitable for transmission. The specification improves the transmission impedance (Transfer lmpedance)' and achieves the purpose of stabilizing and improving the transmission quality. The rear side walls behind the left and right sides of the connector body are each extended with a retaining wall to prevent electromagnetic interference. (10) Ϊ) The effect and the situation that the bare wire (WIRE) part of the CABLE can be prevented from contacting the two side walls of the metal upper case to cause a short circuit can relatively ensure the function of the product. Please refer to the detailed description of the drawings as follows. [Embodiment] As shown in FIG. 4 to FIG. 4, the improved structure of the low-crosstalk interference connector of the present invention includes: a connector body (1) having a frequency for the R-insertion (111). ) and with 4
