Connector and printed circuit board foot pattern for a connector

Abstract

A connector, and printed circuit board foot pattern for a connector which can efficiently transmit a high-speed differential signal are provided. In a connector 1, a contact group 30 includes at least paired adjacent signal contacts SC-SC, and non-paired contacts GC which are placed on both adjacent sides or one adjacent side of the paired signal contacts. The contacts are arranged so that the distance W1 between the paired signal contacts SC-SC is shorter than the distance W2 between adjacent signal and non-paired contacts SC-GC, thereby enhancing the differential coupling force between the paired signal contacts SC-SC.

Description

technical field [0001] The present invention relates to a connector for transmitting high-speed differential signals and a printed circuit board foot pattern for connector. Background technique [0002] Conventionally, a connector has a contact group and an insulator holding the contact group. Each contact of the contact group has a terminal part connected to a connection object and a contact part connected to a mating side contact. Each contact Arranged at equal intervals along the pitch direction perpendicular to the mating and separating direction from the terminal part to the contact part in parallel in the mating and separating direction of the connector and the mating side connector and the distance between adjacent contacts is all equal, The arrangement of the contacts at equal intervals contributes to the cost reduction, productivity improvement, miniaturization and narrow pitch of the connector. [0003] However, in differential transmission, if the distance betwee...

Problems solved by technology

[0006] However, in the above-mentioned Patent Document 1, since the terminal parts are arranged at equal intervals, although it is advantageous to reduce the cost of the connector, reduce the size and narrow the pitch, but on the side of the printed circuit board or the cable that becomes the connection object of the connector, use The differential wiring that is firmly differentially bonded between the paired differential lines also has to be arranged at a pitch equal to the pitch between the terminal parts from the front of the connector.

Therefore, there is a problem that, at the connection portion between the connector and the connection object, the differential coupling force between the differential lines becomes weak, and efficient transmission cannot be performed.
