Problems solved by technology

[0005] In a multi-pole connector, even if a plurality of terminals are arranged in a row at the contact part that is in contact with the terminal of the corresponding connector, by dividing a row of terminals into two rows in the vicinity of the substrate mounting part and converting it into a staggered arrangement, The limitation caused by the pitch of the through holes can be alleviated, and the pitch of the terminals can be further narrowed, so that the multi-pole connector can be further miniaturized and multi-polarized. However, in

Abstract

The invention provides a multipolar connector in which one terminal row can be divided into a plurality of rows (row conversion) while reducing an impedance mismatch. A multipolar connector (1) which is to be insert-mounted on a printed circuit board (100) includes a terminal group (40) in which a plurality of terminals (4) are arranged in one row in contact portions (4a) with respect to terminals of a counter connector, and, while being then passed through a row converting portion (45), one terminal row (41) is divided into a plural-row portion (44) consisting of two rows (42, 43) and functioning as a connecting portion that is opposite to the counter connector, and row-converted to a substantially zigzag arrangement. The terminal group (40) includes two specific terminals (46, 47) in which, in the plural-row portion (44), the terminal width (L1) is wider than the terminal width (L2) of the contact portions (4a). The two specific terminals (46, 47) constitute a terminal pair for transmitting differential signals.

Description

technical field [0001] The present invention relates to a multi-pole connector, in particular to a multi-pole connector mounted on a printed circuit board and having a plurality of terminals for insertion and installation. Background technique [0002] In the case where a plurality of terminals for plug-in mounting of the multi-pole connector are arranged in a row at the contact parts that contact the terminals of the corresponding connector, the substrate mounting parts of the terminals for plug-in mounting are also arranged in a row and protrude outward. , and the substrate mounting portions of the terminals are inserted and soldered into through holes arranged in a row on the printed circuit board (for example, refer to Patent Document 1). [0003] Although there is a strong demand for miniaturization and multi-polarization of multi-pole connectors, there is a problem that even if the existing multi-pole connectors are to be further miniaturized and multi-polarized, the p...
