Description
本發明係關於一種連接器組。 The present invention relates to a connector set.
第M422802號中華民國專利(美國專利公開號US2013196550)揭露一種差動耦合連接器,其包含提供差動訊號之訊號端子及接地端子,其中訊號端子位於接地端子之間。訊號端子及接地端子個別具有本體。訊號端子及接地端子之尾部和接觸部之間是固定節距,而訊號端子之本體間之節距小於訊號端子與相鄰之接地端子之本體之節距。藉由使訊號端子之本體間和訊號端子與相鄰之接地端子之本體間的節距產生變化,提供所欲之優先耦合(preferential coupling)量。 The Republic of China Patent No. M422802 (U.S. Patent Publication No. US2013196550) discloses a differential coupling connector comprising a signal terminal and a ground terminal for providing a differential signal, wherein the signal terminal is located between the ground terminals. The signal terminal and the ground terminal each have a body. The signal terminal and the ground terminal have a fixed pitch between the tail portion and the contact portion, and the pitch between the body of the signal terminal is smaller than the pitch of the signal terminal and the body of the adjacent ground terminal. The amount of preferential coupling is provided by varying the pitch between the body of the signal terminals and the body of the signal terminals and the body of the adjacent ground terminals.
再者,減少訊號端子之本體間的節距可使串音(cross talk)有利的降低。此外,相較於對稱情況,藉減少訊號端子之間的距離(及/或增加訊號端子與相鄰接地端子之間的距離)亦可增加訊號端子上之耦合百分比至少10%,以可降低經由該接地結構傳送之能量,如此可降低在接地端子上之潛在共振能。能量於該等接地端子上之降低可減少能量反射量且因而有助於降低串音。 Furthermore, reducing the pitch between the bodies of the signal terminals can advantageously reduce cross talk. In addition, by reducing the distance between the signal terminals (and/or increasing the distance between the signal terminals and the adjacent ground terminals), the coupling percentage on the signal terminals can be increased by at least 10% compared to the symmetrical case. The energy transmitted by the ground structure reduces the potential resonant energy at the ground terminal. The reduction in energy on the ground terminals reduces the amount of energy reflected and thus helps to reduce crosstalk.
然而,減少訊號端子上之間的距離,雖可使訊號端子間之耦合增加,但同時在減少距離的部分也會使端子阻抗降低,而使端子的整體阻抗不一致,而易造成訊號反射的缺點。 However, reducing the distance between the signal terminals can increase the coupling between the signal terminals, but at the same time, the distance reduction portion also reduces the terminal impedance, and the overall impedance of the terminals is inconsistent, which is easy to cause signal reflection. .
此外,上述專利案之訊號端子之間的間距是有變化的,因為間距有變化而使耦合量也不同,所以當訊號從一間距處傳輸至另一不同間距處時,會產生耦合量變化,造成能量散逸,反而容易增加在接地端子上之潛在共振能,使降低串音的功效減小。 In addition, the spacing between the signal terminals of the above patents varies, because the pitch varies and the coupling amount is different, so when the signal is transmitted from one pitch to another, a change in the coupling amount occurs. This causes energy dissipation, which in turn tends to increase the potential resonance energy at the ground terminal, reducing the effectiveness of reducing crosstalk.
根據上述問題,對應地提出至少一連接器組。 According to the above problem, at least one connector group is correspondingly proposed.
