Description

High-frequency board-to-board connector Technical Field The invention relates to a connector, in particular to a high-frequency board-to-board connector which is suitable for electronic products such as projectors, security equipment and the like. Background The board-to-board connector is used for connecting two PCBs to realize mechanical and electrical connection, and is characterized in that the male and female seats are matched for use, the widths of the contact parts of the male and female seats of the traditional board-to-board connector are almost equal, no compensation allowance is designed in the width direction of the contact parts, however, tolerance accumulation exists in the actually produced product, the matching of the male and female seat terminals is caused, the instability of contact is increased, the contact surface of the terminals of the traditional board-to-board connector is a stamping cut surface, the stamping cut surface is rough, the situation of unstable contact condition and signal disconnection of the terminals is easy to occur in the use process of the connector, and the connector is difficult to test at high frequency. Disclosure of Invention The invention aims to provide a high-frequency board-to-board connector. In order to achieve the above purpose, the invention adopts the following technical scheme: The invention provides a high-frequency board-to-board connector, which comprises a male seat and a female seat which are detachably inserted into each other, wherein in the following description, the direction of inserting the female seat into the male seat is defined as the front-back direction, the female seat is in front, the male seat is in back, and the female seat is inserted into the male seat from front to back. The male seat comprises a male seat main body and a plurality of male seat terminals formed by stamping. The male seat main body is provided with a containing groove for plugging the female seat, a plurality of first slots positioned at the lower side of the containing groove and communicated with the containing groove, and a plurality of second slots positioned at the upper side of the containing groove and communicated with the containing groove. The directions of the second slot and the first slot are respectively defined as an up-down direction, the first slot is arranged below, the second slot is arranged above, and the length direction of the accommodating groove is defined as a left-right direction. The male seat terminals comprise a plurality of first male seat terminals and a plurality of second male seat terminals, wherein the first male seat terminals are provided with first contact arms, the first contact arms are turned by 90 degrees through bending, errors are within +/-10 degrees, the first contact arms are provided with first contact parts, the second male seat terminals are provided with second contact arms, the second contact arms are turned by 90 degrees through bending, errors are within +/-10 degrees, and the second contact arms are provided with second contact parts.
