A low electrical noise board-to-board connector

Abstract

A low electrical noise board-to-board connector comprises a male seat and a female seat. The male seat is provided with a first ground pin, and a second ground pin mating with the first ground pin isprovided on the female seat. The female seat is provided with two rows of female terminals, and the second ground pin comprises a central spacer and at least one ground part, the central spacer is located in the area between the two rows of female terminals, and the bottom end of the central spacer extends away from the male seat and is exposed on the bottom surface of the female seat to form a ground part. The second ground pin is grounded directly from the bottom of the central area of the female seat instead of extending from the side of the female seat, so that the ground path is effectively shortened, and the current can flow through the board-to-board connector more quickly, thereby reducing the electrical noise of the board-to-board connector, and moreover, since the ground path isshortened, the resistance value of the ground pins is reduced, thereby reducing the loss; the central spacer is positioned between two rows of female terminals, increasing the isolation between the two rows of female terminals.

Description

technical field [0001] The invention relates to a radio frequency connector, in particular to a board-to-board connector with low electrical noise. Background technique [0002] The board-to-board connector includes a male seat and a female seat. There are a row of male terminals on the opposite sides of the male seat, and two rows of female terminals corresponding to the male terminals are provided on the female seat. The male terminals match the female terminals. , there is also an island on the female base, the island is located between the two rows of the female terminals, at least one of the male terminals is a first grounding pin, and there is a first grounding pin in the female terminal. pin to match the second ground pin. [0003] In the existing board-to-board connectors, the contact position of the first ground pin and the second ground pin is generally close to the island on the mother base, and the contact point between the first ground pin and the external comp...

Problems solved by technology

[0003] In the existing board-to-board connectors, the contact position of the first ground pin and the second ground pin is generally close to the island on the mother base, and the contact point between the first ground pin and the external component and the second ground pin The contact points with the external components are located outside the side of the board-to-board connector, so the ground path of the board-to-board connector is C-shaped or Z-shaped, whether it is C-shaped or Z-shaped The grounding path of the existing board-to-board connector has the problem of long current transmission path, which causes the existing board-to-board connector to have large electrical noise and serious loss in the process of use.
