Further specifically, in above-mentioned technical proposal, grounding pin before the grounding pin in adjacent two row is respectively is set Connected with the front surface of rear grounding pin, the rear end face of conducting resinl and rear grounding pin shank, the front end face of conducting resinl with before connect The rear surface of ground needle shank connects, such to be designed to facilitate the shield effectiveness for improving connector.

Further specifically, in above-mentioned technical proposal, before the rear end face of the conducting resinl and rear grounding pin shank Surface is arranged in parallel, and the front end face of conducting resinl and the rear surface of preceding grounding pin shank are arranged in parallel, and such be designed to facilitate mentions The shield effectiveness of high connector.

Further specifically, in above-mentioned technical proposal, the grounding pin in adjacent two row is staggered setting, in this way Be designed to facilitate reduce signal pin between crosstalk.

Further specifically, the S-type structure of the conducting resinl is such to be designed to facilitate in above-mentioned technical proposal Reduce the crosstalk between signal pin.

Further specifically, in above-mentioned technical proposal, there are two grounding pins in each row, this two grounding pins it Between have two signal pins, it is such be designed to facilitate reduce signal pin between crosstalk.

The beneficial effects of the utility model are: series connection protected type High speed rear panel connector provided by the utility model, passes through Conducting resinl is introduced, grounding pin is together in series to form shielding using conducting resinl, it can be to carrying out good signal between signal pin Shielding reduces mutual signal interference, improves product high frequency performance.
