Problems solved by technology

[0005] In the terminal structure of the above-mentioned Patent Document 1, although the coupling force between the differential pairs can be strengthened and the influence from other terminals can be weakened, because the width of the differential signal terminal is changed or the differential signal terminal is bent, the difference between the differential pair The impedance is discontinuous due to the uneven spacing, which may affect the signal quality. In addition, when the stand made of insulating material and the terminal are integrated by insert molding, there are difficulties in the mold due to inconsistent terminal shapes and the like. It is difficult to ensure the accuracy of production

Abstract

The invention relates to a multipolar connector for efficiently transmitting high-speed differential signals between electronic apparatuses, and provides a multipolar connector in which the coupling force between a differential pair can be enhanced, an influence of a non-paired terminal can be reduced, and a signal can be transmitted also in a connector portion in the differential mode, and which has excellent high speed transmission characteristics. A multipolar connector 1 has a housing 2 made of an insulating material, and a plurality of terminals P1 to P6 which are held by the housing 2. The plurality of terminals P1 to P6 include: a terminal pair P3, P4 in which two terminals P3, P4 that are adjacent to each other while disposing a first gap A are paired; and one non-paired terminal P2 or P5 which is adjacent to the terminal pair P3, P4 while disposing a second gap B. The terminal pair P3, P4 is a pair for transmitting differential signals. The first gap A is narrower than the second gap B.

Description

technical field [0001] The present invention relates to multi-pole connectors for efficient transmission of high-speed differential signals between electronic devices. Background technique [0002] In a multi-pole connector for high-speed differential signal transmission, if the differential signal terminals and other terminals (such as external terminals such as power terminals and ground terminals (that is, terminals other than paired terminals)) are arranged at equal intervals , the bonding force between the differential pairs cannot be fully ensured, and the transmission mode is relatively close to single mode. Compared with differential-mode transmission, single-mode transmission has inferior characteristics such as signal speed, skew, and noise. In addition, if the pitch is simply reduced in order to strengthen the bonding force, the impedance will be too low relative to the set impedance or the rated value due to the influence of the other terminals, making it diffic...
