[0055] In this embodiment, two outer shields 6 are detachably fastened to the two outer sides 12 of the insulating housing 1. Each outer shield 6 includes a plurality of elastic arms 61 corresponding to the plurality of through holes 17. The plurality of elastic arms 61 of the two outer shields 6 respectively pass through the plurality of through holes 17 of the insulating housing 1 and detachably abut against the plurality of grounding terminals 31, so that the plurality of grounding members 3 can be electrically connected to each other through any one of the outer shields 6.

[0056] In this embodiment, the plurality of grounding members 3, the inner shield 5 and the outer shields 6 of the connector 100 are electrically connected to each other to achieve a common grounding effect, and can jointly divide the inside of the connector 100 into a plurality of shielding chambers. Each shielding chamber accommodates a differential signal pair, so that the plurality of differential signal pairs are effectively separated, enabling the connector 100 to have a better signal transmission effect.

[0057] Each outer shield 6 in this embodiment includes a plurality of fastening holes 62, and the plurality of fastening holes 62 of each outer shield 6 are respectively fastened to the plurality of fastening blocks 14 on the corresponding outer side 12 of the insulating housing 1. Each outer shield 6 further includes a plurality of positioning claws 63, and the plurality of positioning claws 63 of the two outer shields 6 respectively abut against the two guiding surfaces 13 of the insulating housing 1, so that the two outer shields 6 can be stably fastened to the two outer sides 12 of the insulating housing 1.

[0058] In this embodiment, the mating connector 7 includes a mating housing 71, a plurality of signal mating terminals 72, a plurality of ground mating terminals 73, and a plurality of power mating terminals 74. The above-mentioned plurality of signal mating terminals 72, plurality of ground mating terminals 73, and plurality of power mating terminals 74 are all fixed to the mating housing 71. When the connector 100 and the mating connector 7 are inserted into each other along the above-mentioned insertion direction S, the signal contact sections 22 of the plurality of signal terminals 2 respectively abut against the plurality of signal mating terminals 72, the plurality of ground terminals 31 (ground contact sections 312) respectively abut against the plurality of ground mating terminals 73, and the plurality of power mating terminals 74 respectively abut against the plurality of power terminals 4. More specifically, when the connector 100 and the mating connector 7 are inserted into each other along the above-mentioned insertion direction S, two contact points 3121 of each ground contact section 312 are simultaneously in contact with the corresponding ground mating terminal 73, and the main transmission point 223 and the secondary transmission point 224 of each signal contact section 22 are simultaneously in contact with the corresponding signal mating terminal 72. The second distance D2 between each main transmission point 223 and the free end 721 of the corresponding signal mating terminal 72 is less than the first distance D1 and less than 10% of the total length of the corresponding signal mating terminal 72.

[0059] In this embodiment, the main transmission point 223 and the secondary transmission point 224 of each signal terminal 2 can be simultaneously in contact with the corresponding signal mating terminal 72, so as to improve the high-frequency signal transmission performance of this embodiment through a signal transmission structure different from the prior art. Further, in this embodiment, the secondary transmission point 224 of each signal terminal 2 can (or only) perform signal transmission when the main transmission point 223 is separated from the corresponding signal mating terminal 72 due to an external force vibration in this embodiment. By forming the main transmission point 223 and the secondary transmission point 224 on each signal terminal 2 in this embodiment, the above-mentioned second distance D2 between the free end 721 of each signal mating terminal 72 and the corresponding main transmission point 223 can be reduced, thereby effectively reducing the influence of the stub effect on signal transmission.

[0060] The present invention can make the main transmission point 223 and the secondary transmission point 224 of each signal terminal contact the corresponding signal mating terminal 72 simultaneously, so as to improve the high-frequency signal transmission performance of the high-speed connector through a signal transmission structure different from the prior art. Moreover, by forming the main transmission point 223 and the secondary transmission point 224 on each signal terminal in the present invention, the distance between the free end 721 of each signal mating terminal 72 and the corresponding main transmission point 223 can be reduced, thereby effectively reducing the influence of the stub effect on signal transmission. For the internal connector 100 of the present invention, a plurality of grounding members 3, an internal shielding member 5 and an external shielding member 6 are electrically connected to each other to achieve a common grounding effect, and can jointly divide the interior of the connector 100 into a plurality of shielding chambers, and each shielding chamber accommodates a differential signal pair, so that a plurality of differential signal pairs are effectively separated, enabling the connector 100 to have a better signal transmission effect.

[0061] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
