Differential-type connector for transmission

Abstract

The invention relates to the technical field of connectors, in particular to a differential-type connector for transmission. A row of elastic rods are arranged on a male plug, are equally arranged andcan be used for changing a position of a male plug contact terminal, a female plug comprises a female plug shell, a terminal support part and a female plug contact terminal, the terminal support partis fixedly connected with an accommodating cavity in an opening end of the female plug shell by welding, an accommodating groove is formed in an upper end surface of the terminal support part and isused for placing the female plug contact terminal, two groups of terminal blocking plates with same height and different widths are equally connected in the accommodating groove, a plurality of femaleplug contact terminals are arranged in the accommodating groove and are arranged between adjacent terminal blocking plates, and a sliding groove is formed in one side, near to the female plug contactterminal, of each terminal blocking plate. By the differential-type connector for transmission, the clamping sealing performance of the male plug and the female plug is improved, the interference ofexternal air is reduced, the transmission rate is improved, and the differential-type connector for transmission has the remarkable substantive characteristic and the remarkable progress.

[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 pairs of terminals)) are arranged at equal intervals , the bonding force between differential pairs cannot be fully ensured, and the transmission mode is closer to single mode

Compared with differential mode transmission, single-mode transmission has poorer characteristics such as signal speed, skew, and noise, and if the pitch is simply reduced to strengthen the above-mentioned bonding force, the impedance will be relatively set due to the influence of other terminals. The impedance or rated value is too low, so it is difficult to realize the differential mode transmission at equal intervals in the connector part of the differential impedance of the 100Q series. The existing technology changes the width of the differential signal terminal or bends the differential signal terminal. The pitch interval between the contact parts connected with the mating terminal of the differential signal terminal is narrower than the pitch interval between the contact part of the differential signal terminal and the contact parts of other terminals adjacent to the differential signal terminal, although it can strengthen The bonding force between the differential pairs and the influence from other terminals are weakened, but because the width of the differential signal terminals is changed or the differential signal terminals are bent, the impedance is discontinuous due to the uneven spacing of the differential pairs, which may affect For signal quality, when the stand formed of insulating material and the terminal are integrated by insert molding, there is a problem that the simulation is difficult to make and the accuracy is difficult to ensure due to the inconsistency of the shape of the terminal. For this reason, we propose a differential transmission with connector
