The technical scheme that the present invention solves its technical problem employing is: a kind of printed board and backboard high-speed signal connector master base structure, master base structure comprises plastic cement insulator and substrate, on described plastic cement insulator, have inserting groove more than a row, in every socket access slot, be fitted with a substrate, described substrate comprises matrix, be fixedly installed in matrix and one end is exposed to the termination of matrix side and is arranged on the five metals principal piece of another side of matrix, in five metals principal piece, be fixed with more than one group engagement reed, the side that substrate is provided with engagement reed is inserted in inserting groove, described engagement reed is provided with the correcting boss raising up, both sides corresponding to correcting boss in inserting groove on plastic cement insulator are respectively equipped with positive stop lug boss, positive stop lug boss top is provided with correcting curved surface.
The technical scheme that the present invention solves its technical problem employing further comprises:
One group of described engagement reed comprises two engagement reeds, two corresponding settings of reed.
Described engagement reed is the distortion at 90 ° of angles in centre position, the direction of twist of two engagement reeds in one group of engagement reed is contrary.
The top of two engagement reeds in one group of described engagement reed separates to two ends.
Described correcting curved surface one side is provided with correcting confined planes corresponding to the position of correcting boss.
The invention has the beneficial effects as follows: it is placed in the middle that the present invention can guarantee that whole engagement reed terminal is arranged on plastic cement insulator in inserting groove to position, and consistency is good, good to inserting engagement with male end contact, can guarantee that high speed signal effectively transmits.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
