Description
本發明係有關於一種高速電連接器組合，尤指一種可改善共振頻率發生之高速電連接器組合以及耦接本發明高速電連接器組合之電路板。 The invention relates to a high-speed electrical connector combination, in particular to a high-speed electrical connector combination capable of improving the occurrence of a resonance frequency, and a circuit board coupled to the high-speed electrical connector combination of the invention.
高速電連接器係利用信號接點而在電子裝置之間提供信號連接。通常，該等信號接點係如此地緊密間隔而使得在相鄰信號接點之間會發生不當的干擾或“串音”。在一信號接點中之一信號由於干擾時改變電磁場而引致一相鄰信號接點中之電氣干擾時便會發生串音，其因而會破壞信號完整性。串音亦會發生在差動訊號對之間。串音會隨著在相干擾之訊號接點之間的距離縮短而增加。串音亦可藉由使用接地接點分離相鄰信號接點或相鄰差動信號對而予以降低。 High-speed electrical connectors use signal contacts to provide signal connections between electronic devices. Generally, such signal contacts are so closely spaced that improper interference or "crosstalk" can occur between adjacent signal contacts. Crosstalk occurs when one of the signals in a signal contact changes the electromagnetic field due to interference, which causes electrical interference in an adjacent signal contact, which can damage the signal integrity. Crosstalk can also occur between differential signal pairs. Crosstalk increases as the distance between interfering signal contacts decreases. Crosstalk can also be reduced by using ground contacts to separate adjacent signal contacts or adjacent differential signal pairs.
習知水平插接之高速電連接器之導電端子之排列為GSSGSSG，會導致共振頻率的產生，然而在共振的頻率點上，近端及遠端之串音干擾會被顯著地增強，如第十三圖所示，此習知高速電連接器在共振頻率為3.6GHz及7.4GHz時會產生-17.7dB及-12.3dB的近端串音干擾訊號，而在共振頻率為3.6GHz及7.4GHz時會產生-18.8dB及-17.7dB的遠端串音干擾 訊號，此些串音干擾訊號會使高速電連接器產生誤動作。 It is known that the arrangement of the conductive terminals of a horizontally inserted high-speed electrical connector is GSSGSSG, which will cause the generation of a resonance frequency. However, at the frequency point of the resonance, the crosstalk interference at the near end and the far end will be significantly enhanced, as shown in the figure. As shown in the thirteenth figure, this conventional high-speed electrical connector generates near-end crosstalk interference signals of -17.7dB and -12.3dB at the resonance frequencies of 3.6GHz and 7.4GHz, and at the resonance frequencies of 3.6GHz and 7.4GHz. Will produce -18.8dB and -17.7dB far-end crosstalk interference Signals, these crosstalk interference signals can cause malfunction of high-speed electrical connectors.
另一種習知垂直插接之高速電連接器之導電端子係呈二列排列方式，其二列之導電端子的排列為錯置之G S S G S S G的排列方式，此排列方式亦會導致共振頻率的產生，且在共振的頻率點上，近端及遠端之串音干擾亦會被顯著地增強，如第十四圖所示，此習知高速電連接器在共振頻率為6.2GHz、11.2GHz、15.4GHz及17.8GHz時會產生-19.4dB、-17.4dB、-25dB及-15.8dB的近端串音干擾訊號，而在共振頻率為6.2GHz、11.2GHz、15.4GHz及17.8GHz時會產生-1.8dB、-2.7dB、-2.1dB及-8dB的遠端串音干擾訊號，此些串音干擾訊號會使高速電連接器產生誤動作。 The conductive terminals of another conventional high-speed electrical connector are arranged in a two-row arrangement. The arrangement of the conductive terminals in the two rows is a misaligned GSSGSSG arrangement. This arrangement also results in the generation of resonance frequencies. And at the frequency of resonance, the near-end and far-end crosstalk interference will be significantly enhanced. As shown in Figure 14, this conventional high-speed electrical connector has resonance frequencies of 6.2GHz, 11.2GHz, and 15.4. Near-end crosstalk interference signals of -19.4dB, -17.4dB, -25dB, and -15.8dB are generated at GHz and 17.8GHz, and -1.8 is generated at resonance frequencies of 6.2GHz, 11.2GHz, 15.4GHz, and 17.8GHz. Far-end crosstalk interference signals of dB, -2.7dB, -2.1dB, and -8dB. These crosstalk interference signals can cause high-speed electrical connectors to malfunction.
隨著電子裝置微型化及高速信號傳輸，高信號完整性的電子通信及串音之降低變成連接器設計中之一重要因素。因此希望可提供一改良式連接器，其可改善共振頻率的發生進而降低串音之影響程度，尤指係針對高速連接器。 With the miniaturization of electronic devices and high-speed signal transmission, electronic communication with high signal integrity and reduction of crosstalk become an important factor in connector design. Therefore, it is desirable to provide an improved connector, which can improve the occurrence of resonance frequency and reduce the influence of crosstalk, especially for high-speed connectors.

請參考第一圖，係顯示習知線路承載電流之示意圖。如圖所示，根據習知的理論，當線路1承載時變電流i1時，會耦合電流i2在線路2以反方向流動，其i2大小由電流i1和耦合係數K來決定，當線路2用以承載迴流電流時，此時耦合電流i2會提高迴流電流，接著此被提高的迴流電流會產生耦合電流在線路1，進而提高原本的時變電流i1，因此系統的整體能量在線路1和線路2之間來來回回地交換，此時若是有外界的干擾源時，就提高了共振頻率發生的機會。 Please refer to the first figure, which is a schematic diagram showing a conventional line carrying current. As shown in the figure, according to the conventional theory, when line 1 carries a time-varying current i 1 , a coupling current i 2 flows in the opposite direction on line 2, and the size of i 2 is determined by the current i 1 and the coupling coefficient K. When line 2 is used to carry the return current, the coupling current i 2 will increase the return current, and then the increased return current will generate a coupling current on line 1, thereby increasing the original time-varying current i 1 , so the overall system Energy is exchanged back and forth between line 1 and line 2. At this time, if there is an external interference source, the chance of resonance frequency is increased.
請參考第二圖，係顯示本發明高速連接器之線路承載電流之示意圖。根據上述第一圖習知的理論，高速訊號的迴流電流自然傾向於往低阻抗的路徑流動，因此，如本發明第二圖所示，當一差動訊號之大小相等和極性相反的i1和i2分別在端子1(Pin+1)和端子3(Pin-3)以相反的方向流動，並且將其唯一的接地端子2(Pin 2)設置於端子1和端子3的中間，造成端子1和端子2間之耦合係數K1等於端子3和端子2間的耦合係數K2，進而導致端子1耦合到端子2之耦合電流和端子3耦合到端子2之耦合電流相同，由於此兩耦合電流之大小相等並極性相反，因此二耦合電流在接地端子2可以相互抵消。再者，根據上述之基礎理論，在本發明中，兩鄰近的差動訊號端子對之間，並無設置任何的接地端子，以抑制共振頻率的發生。 Please refer to the second figure, which is a schematic diagram showing the current carried by the line of the high-speed connector of the present invention. According to the first conventional theory FIG return current path of high speed signals naturally tends to flow toward lower impedance, and therefore, as shown in the second view of the invention, when a differential signal of equal magnitude and opposite polarity i 1 And i 2 flow in opposite directions at terminal 1 (Pin + 1) and terminal 3 (Pin-3) respectively, and their only ground terminal 2 (Pin 2) is placed in the middle of terminal 1 and terminal 3, causing the terminal terminal coupling coefficient and 2 of K 1 is equal to the terminal coupling coefficient of 3 and 2 between the terminals K 2, leading to terminal 1 coupled to the coupling the coupling current and the terminal pin 2 of 3 to the same terminal 2 of the coupling current, since this two coupling The magnitudes of the currents are equal and their polarities are opposite, so the two coupling currents can cancel each other at the ground terminal 2. Furthermore, according to the above-mentioned basic theory, in the present invention, no ground terminal is provided between two adjacent differential signal terminal pairs to suppress the occurrence of resonance frequency.
