Description
本發明是有關於一種電連接器的耦合端子結構及電連接器，尤指一種利用端子間的結構特性而產生由電磁耦合效應，以達到改善串擾干擾的電連接器的耦合端子結構及電連接器。The invention relates to a coupling terminal structure and an electrical connector of an electrical connector, in particular to a coupling terminal structure and an electrical connection of an electrical connector which utilizes structural characteristics between terminals to generate an electromagnetic coupling effect to improve crosstalk interference. Device.
習知的電連接器的耦合端子的結構如圖1所繪示，第一端子1及第二端子2彼此大致呈相同樣式及結構，且兩者從頭到尾各部位彼此相對上大致呈平行。故舉例來說，假設有一第一橫切線C1分別在兩並排且結構一致的第一端子1與第二端子2上較左端處切出兩第一橫切點(11,21)，兩第一橫切點(11,21)之間的相對距離為針腳間距P；又如有一第二橫切線C2亦分別在所述第一端子1與第二端子2上的中間段落切出兩第二橫切點(12,22)，兩第二橫切點(12,22)之間的相對距離也基本上等同於針腳間距P，此為有關耦合端子一般的習知做法及結構安排。The structure of the coupling terminal of the conventional electrical connector is as shown in FIG. 1 . The first terminal 1 and the second terminal 2 have substantially the same pattern and structure, and the two portions are substantially parallel to each other from head to tail. For example, suppose a first transverse line C1 cuts two first cross-cut points (11, 21) at the left end of the first terminal 1 and the second terminal 2 which are arranged side by side and have the same structure. The relative distance between the tangent points (11, 21) is the stitch pitch P; and if there is a second cross-cut line C2, two second cross-cut points are also cut in the middle sections of the first terminal 1 and the second terminal 2, respectively. 12, 22), the relative distance between the two second transverse tangent points (12, 22) is also substantially equivalent to the stitch pitch P, which is a common practice and structural arrangement for the coupling terminal.
然而鄰近端子間或端子自身卻始終存在著串擾(cross-talk)的干擾問題，尤其當電連接器用於高速資料傳輸時(如3Gbps)，為了在短時間傳輸大量的資料，其電信號需要較高的頻寬，因此電信號的工作頻率亦極高，可能在3GHz至5GHz間或更高，隨著工作頻率的增高所產生的串擾更是嚴重，隨即影響資料傳輸的完整性或產生位元錯誤(bit error)。However, there is always cross-talk interference between adjacent terminals or terminals themselves, especially when the electrical connector is used for high-speed data transmission (such as 3 Gbps). In order to transmit a large amount of data in a short time, the electrical signal needs to be compared. High bandwidth, so the operating frequency of the electrical signal is also very high, possibly between 3 GHz and 5 GHz or higher. As the working frequency increases, the crosstalk is more serious, which will affect the integrity of the data transmission or generate bits. Error (bit error).
故如無法做到鄰近端子間完善的屏蔽以降低串擾，就 只好改為降低電信號的工作頻率，而導致資料傳輸速率產生瓶頸而無法被大幅提高。即使可有效做到鄰近端子間的屏蔽，也多會因為屏蔽元件或接地元件的增加而導致電連接器體積、重量無法被有效縮小，這顯然違背了現今各電子元件均朝微型化發展的趨勢，而且還徒然增加製造成本。Therefore, if the perfect shielding between adjacent terminals is not possible to reduce crosstalk, It was changed to reduce the operating frequency of the electrical signal, which caused the data transmission rate to have a bottleneck and could not be greatly improved. Even if the shielding between adjacent terminals can be effectively performed, the volume and weight of the electrical connector cannot be effectively reduced due to the increase of the shielding component or the grounding component, which obviously contradicts the trend of miniaturization of various electronic components. And it also increases manufacturing costs in vain.

Taking the upper two terminals as an example, it includes: the first terminal 10 and the second terminal 20 of the paired pairs, and are juxtaposed with each other to form a three-dimensional The terminal cluster CL, shown in Figure 2 is a 2 x 5 terminal cluster CL, but not limited to this, the terminal cluster CL can also be 4 x 5, 6 x 5 or 4 x 8 ... The first terminal 10 and the second terminal 20 may be any type of electrical terminal, such as a single-ended signal terminal, a differential signal terminal pair, or a ground terminal. For the preferred example of the differential signal terminal pair, the first terminal 10 and the second terminal 20 are respectively a positive differential signal terminal and a negative differential signal terminal.
結構上，第一端子10自其一頭端則依序包含有一第一接觸端部11、一第一頸部12及一第一延伸部13。第二端子20則自其一頭端則依序包含有一對應於所述第一接觸端部11的第二接觸端部21、一對應於所述第一頸部12的第二頸部22及一對應於第一延伸部13的第二延伸部23，而且第一接觸端部11與第二接觸端部21彼此相距有一第一間距D1，第一延伸部13與第二延伸部23彼此相距有一第二間距D2，而且第一間距D1大於第二間距D2，第一延伸部13及第二延伸部23大抵皆分別為一具有寬面(圖2，標號略)及窄面(圖2，標號略)的條狀導電物，較佳地，第一延伸部13的寬面朝向第二延伸部的寬面，以加強所產生之電磁耦合效應。Structurally, the first terminal 10 includes a first contact end portion 11, a first neck portion 12 and a first extension portion 13 in sequence from one end thereof. The second terminal 20 sequentially includes a second contact end portion 21 corresponding to the first contact end portion 11 , a second neck portion 22 corresponding to the first neck portion 12 , and a first end end Corresponding to the second extending portion 23 of the first extending portion 13, and the first contact end portion 11 and the second contact end portion 21 are spaced apart from each other by a first spacing D1, and the first extending portion 13 and the second extending portion 23 are spaced apart from each other. The second spacing D2, and the first spacing D1 is greater than the second spacing D2, the first extending portion 13 and the second extending portion 23 are each substantially a wide surface (FIG. 2, slightly omitted) and a narrow surface (FIG. 2, label) Preferably, the strip-shaped conductive material preferably has a wide surface of the first extending portion 13 facing the wide surface of the second extending portion to enhance the electromagnetic coupling effect generated.
因此從圖示之中可以了解到，本發明為了達到改善端子之間串擾干擾的問題，本發明的端子之間的結構，皆至少須具有其第一接觸端部11與第二接觸端部21之間的第一間距D1大於第一延伸部13與第二延伸部23之間的第二 間距D2的結構特徵。以第一端子10為例，只要符合上述特徵，那麼連接第一接觸端部11與第一延伸部13之間的第一頸部12，則不限定須以何種特定方式或結構來進行第一接觸端部11與第一延伸部13之間的連接，同理，第二頸部22亦是如此。Therefore, it can be understood from the drawings that in order to achieve the problem of improving crosstalk interference between terminals, the structure between the terminals of the present invention must have at least a first contact end portion 11 and a second contact end portion 21 thereof. The first spacing D1 between is greater than the second between the first extension 13 and the second extension 23 Structural features of the spacing D2. Taking the first terminal 10 as an example, if the first neck portion 12 between the first contact end portion 11 and the first extending portion 13 is connected, the first neck portion 12 is not limited in any particular manner or structure. The connection between the contact end portion 11 and the first extension portion 13 is the same, and the second neck portion 22 is also the same.
為了方便說明，如圖3所繪示，本發明以在俯視角上，相對於對稱軸AX而兩兩對稱的第一端子10與第二端子20進行說明，若將對稱軸AX比喻為一面鏡子，可發現第一端子10的整體結構與第二端子20的整體結構大致互呈鏡像關係或互成對掌關係，並可類推至如圖2或圖4之除第一端子10及第二端子20以外的其他端子，但仍不以此對稱的結構為限。如從圖3所示，以第一接觸端部11作為出發點，第一頸部12則以朝對稱軸AX靠近的方式而向內彎折延伸，且連接到第一延伸部13，而且第二頸部22對稱於第一頸部12，也以朝對稱軸AX靠近的方式而向內彎折，接著延伸到第二延伸部23。因此為了使第一間距D1大於第二間距D2，在端子的製造上，通常會對其中任一端子中間段落進行沖折加壓，以形成朝其中另一端子的方向或朝對稱軸AX的方向而向內彎折的第一頸部12及第二頸部22，如此第一頸部12及第二頸部22後段部份的延伸部13及延伸部23之間的第二間距D2即自然小於第一間距D1。For convenience of description, as shown in FIG. 3, the present invention is described with respect to the first terminal 10 and the second terminal 20 which are symmetric with respect to the axis of symmetry AX at a plan view angle, and if the axis of symmetry AX is referred to as a mirror It can be found that the overall structure of the first terminal 10 and the overall structure of the second terminal 20 are substantially mirror images or mutually in a palm relationship, and can be analogized to the first terminal 10 and the second terminal as shown in FIG. 2 or FIG. 4 . Other terminals than 20, but still not limited to this symmetrical structure. As shown in FIG. 3, with the first contact end portion 11 as a starting point, the first neck portion 12 is bent inwardly toward the axis of symmetry AX, and is connected to the first extension portion 13, and second. The neck 22 is symmetrical to the first neck portion 12 and is also bent inwardly toward the axis of symmetry AX, and then extends to the second extension portion 23. Therefore, in order to make the first pitch D1 larger than the second pitch D2, in the manufacture of the terminal, the middle section of any of the terminals is usually punched and pressed to form a direction toward the other terminal or a direction toward the axis of symmetry AX. The first neck portion 12 and the second neck portion 22 bent inwardly, such that the second portion D2 between the extending portion 13 of the rear portion of the first neck portion 12 and the second neck portion 22 and the extending portion 23 is naturally Less than the first spacing D1.
而較佳地，第一間距D1與第二間距D2之間的比例為40：7(其比值為5.714)至40：15(其比值為2.667)之間，從更精確的實施範例來說，第一間距D1實際寬度可為2公釐，第二間距D2的實際寬度可為0.55公釐。Preferably, the ratio between the first pitch D1 and the second pitch D2 is between 40:7 (the ratio of which is 5.714) to 40:15 (the ratio of which is 2.667), from a more precise embodiment, The first pitch D1 may have an actual width of 2 mm, and the second pitch D2 may have an actual width of 0.55 mm.
此外，為了配合一般電連接器的介電殼體結構規格或使用習慣，第一接觸端部11可平行於第二接觸端部21，或是第一接觸端部11可對稱於第二接觸端部21。如以圖4的第一接觸端部11作為說明，第一接觸端部11更可包含有一第一夾持部111，第一挾持部111進一步包含有一上夾持墊片1111及一下夾持墊片1112，其中上夾持墊片1111與下夾持墊片1112分別呈一彎弧狀，以使彼此間的間距更小，而在上、下夾持墊片1111、1112之間形成一相對最窄的距離，如此可取得一緊配效果更佳的挾持效果。上、下夾持墊片1111的端部更因為上述之彎弧狀，而分別形成一上翹起端1113以及一下翹起端1114，使上翹起端1113至下翹起端1114在上、下夾持墊片1111、1112之間形成一相對最寬的開口，藉著由寬至窄的結構可在另一連接端子的公插***時，給予一***的導引，更可有利於一公插(圖略，未繪示)的***，同理，與第一端子10成對的第二端子20也有上述第一夾持部111結構相當的第二夾持部(請見圖2，以下標號略)，因此第二挾持部進一步包含有一上夾持墊片(標號略)及一下夾持墊片(標號略)，其中第二夾持部的上夾持墊片與下夾持墊片分別呈一彎弧狀，以使彼此間的間距更小，而在第二夾持部的上、下夾持墊片之間形成一相對最窄的距離，如此可取得一緊配效果更佳的挾持效果。In addition, in order to conform to the dielectric housing structure specifications or usage habits of a general electrical connector, the first contact end portion 11 may be parallel to the second contact end portion 21, or the first contact end portion 11 may be symmetrical to the second contact end portion. Department 21. As shown in FIG. 4 , the first contact end portion 11 further includes a first clamping portion 111 . The first clamping portion 111 further includes an upper clamping spacer 1111 and a lower clamping pad. The sheet 1112, wherein the upper clamping spacer 1111 and the lower clamping spacer 1112 are respectively curved in an arc shape to make the spacing between the two smaller, and a relative between the upper and lower clamping spacers 1111 and 1112 is formed. The narrowest distance, so that a better matching effect can be achieved. The ends of the upper and lower clamping spacers 1111 are further formed by an upwardly curved end 1113 and a lower raised end 1114, respectively, so that the upper raised end 1113 to the lower raised end 1114 are on, A relatively widest opening is formed between the lower clamping pads 1111 and 1112. By the wide to narrow structure, an insertion guide can be given when the male insertion of the other connection terminal is inserted, which is more advantageous for one. The insertion of the male plug (not shown), in the same way, the second terminal 20 paired with the first terminal 10 also has the second clamping portion corresponding to the structure of the first clamping portion 111 (see FIG. 2, The second holding portion further includes an upper clamping pad (not shown) and a lower clamping pad (not shown), wherein the upper clamping pad and the lower clamping pad of the second clamping portion The sheets are respectively curved in an arc shape so as to make the spacing between them smaller, and a relatively narrow distance is formed between the upper and lower clamping pads of the second clamping portion, so that a tight fitting effect can be obtained. Good holding effect.
又，如圖2、圖3及圖4所繪示，以第一端子10為例，其第一頸部12靠近第一接觸端部11之處，還包含有一第一扭轉部121，其目的在於第一延伸部13為寬面 W朝側，窄面(未標號)朝下(圖4)，然而為了使第一接觸端部11形成如上一段所述有利於一公插***的結構，故利用第一扭轉部121而使第一接觸端部11可沿其縱向自轉，以使其窄面(N)可以朝側，寬面W可以朝上或朝下。同理，就第二端子20而言，其第二頸部22靠近第二接觸端部21之處，還包含有一第二扭轉部221，故利用第二扭轉部221而使第二接觸端部21可沿其縱向自轉，以使其窄面N可以朝側(如：圖2)，寬面W可以朝上或朝下，從而使第一接觸端部11的窄面N朝向第二接觸端部21的窄面N。Moreover, as shown in FIG. 2, FIG. 3 and FIG. 4, the first terminal 10 is taken as an example, and the first neck portion 12 is adjacent to the first contact end portion 11, and further includes a first torsion portion 121. In the first extension 13 is a wide face W is on the side, the narrow side (not numbered) is facing downward (Fig. 4), however, in order to make the first contact end portion 11 form a structure which facilitates a male insertion as described in the above paragraph, the first torsion portion 121 is used to make the first A contact end portion 11 is rotatable in its longitudinal direction such that its narrow face (N) can be directed toward the side, and the wide face W can be directed upward or downward. Similarly, in the second terminal 20, the second neck portion 22 is adjacent to the second contact end portion 21, and further includes a second torsion portion 221, so that the second contact portion is used to make the second contact end portion 21 can be rotated in its longitudinal direction so that its narrow face N can be directed to the side (eg, FIG. 2), and the wide face W can be upward or downward so that the narrow face N of the first contact end 11 faces the second contact end The narrow side N of the portion 21.
較佳地，第一端子10自第一延伸部13還可進一步依序延伸出有一第三頸部14及一第三接觸端部15，換言之，第一接觸端部11及第三接觸端部15分別位於第一端子10的兩端。Preferably, the first terminal 10 further extends from the first extending portion 13 to a third neck portion 14 and a third contact end portion 15, in other words, the first contact end portion 11 and the third contact end portion. 15 are respectively located at both ends of the first terminal 10.
類似地，第二端子20自第二延伸部23還可進一步依序延伸出一對應於第三頸部14的第四頸部24及一對應於該第三接觸端部15的第四接觸端部25。在本實施例第三接觸端部15與第四接觸端部25皆為魚眼針腳，但不以此為限，第三接觸端部15與第四接觸端部25作為本發明第一端10及第二端子20的另一端部，可為任何規格、形式的電性接點、針腳、母插或公插，然而最重要的是，第三接觸端部15與第四接觸端部25彼此亦相距有一第三間距D3，第三間距D3須大於第二間距D2，第三間距D3與第一間距D1之間的相對大小則不限定，但是較佳地，第三間距D3可等於第一間距D1。而第三頸部14與第四頸部15個別的結構或其相對之間 的結構，則如上述第一頸部12與第二頸部22的範例一樣，不再贅述。Similarly, the second terminal 20 can further extend from the second extending portion 23 to a fourth neck portion 24 corresponding to the third neck portion 14 and a fourth contact end corresponding to the third contact end portion 15. Part 25. In the present embodiment, the third contact end portion 15 and the fourth contact end portion 25 are both fisheye pins, but not limited thereto, the third contact end portion 15 and the fourth contact end portion 25 serve as the first end 10 of the present invention. And the other end of the second terminal 20 can be any size, form of electrical contact, pin, female plug or male plug, but most importantly, the third contact end 15 and the fourth contact end 25 are mutually There is also a third spacing D3, the third spacing D3 must be greater than the second spacing D2, the relative size between the third spacing D3 and the first spacing D1 is not limited, but preferably, the third spacing D3 can be equal to the first Spacing D1. And the individual structures of the third neck portion 14 and the fourth neck portion 15 or their relative The structure is the same as the example of the first neck portion 12 and the second neck portion 22 described above, and will not be described again.
較佳地，本發明以電連接器中的直角配接器做為示範，是以第一延伸部13還可具有一第一彎折部131，第一彎折部131通常作一接近直角角度的彎折，如以圖4為例，此彎折為朝下，但不以此為限，亦可朝上、朝出圖4紙面或朝入圖4紙面的方向彎折，彎折的角度亦不限。請復回到圖2及圖4，第一彎折部131可用以導引第三接觸端部15所朝的方向，以將第三接觸端部15與第一接觸端部11兩者各自所朝方向導引至互為垂直的相對關係。而第二延伸部23還具有一對應於該第一彎折部131的第二彎折部231，故藉由第二彎折部231對第四接觸端部25的帶動、導引，亦會將第四接觸端部25與第二接觸端部21兩者各自所朝方向導引至互為垂直的相對關係。然而無論第一彎折部131與第二彎折部231如何彎折，最後結果皆須符合本發明如上所述之第三間距D3大於第二間距D2。Preferably, the present invention is exemplified by a right angle adapter in the electrical connector, such that the first extension portion 13 can further have a first bent portion 131, and the first bent portion 131 is generally a near right angle. For example, in the case of FIG. 4, the bending is downward, but not limited thereto, and may be bent upwards, toward the paper surface of FIG. 4 or in the direction of the paper surface of FIG. 4, and the bending angle is Not limited. Referring back to FIG. 2 and FIG. 4, the first bent portion 131 can be used to guide the direction in which the third contact end portion 15 faces, so that the third contact end portion 15 and the first contact end portion 11 are respectively Guide the direction to each other in a vertical relationship. The second extension portion 23 further has a second bending portion 231 corresponding to the first bending portion 131. Therefore, the second bending portion 231 can be driven and guided by the second bending portion 231. The fourth contact end portion 25 and the second contact end portion 21 are each guided in a direction perpendicular to each other. However, no matter how the first bent portion 131 and the second bent portion 231 are bent, the final result must conform to the third pitch D3 of the present invention as described above is greater than the second pitch D2.
在此附帶說明的是，上述第一間距D1、第二間距D2及第三間距D3的定義及測量方式為：如以第一間距D1為例，是依第一接觸端部11、第二接觸端部21兩者中心軸(如圖3，標號略)之間的距離所定義且依此測量而得，第二間距D2、第三間距D3亦為如此。It is to be noted that, the first spacing D1, the second spacing D2, and the third spacing D3 are defined and measured in such a manner that, as exemplified by the first spacing D1, the first contact end portion 11 and the second contact are The distance between the central axes of the ends 21 (as shown in FIG. 3, abbreviated as follows) is defined and measured accordingly, as is the second pitch D2 and the third pitch D3.
然而上述之第一彎折部131的結構，如非使用在直角配接器時，則可能變得不必要；又以圖2、圖4中下方的第一端子10’為例，可了解到其第三接觸端部15’最後可以朝下，乃是由第三頸部14’起自第一延伸部13’而直接向下延 伸，則可發現，其第一彎折部131’的結構特徵雖存在，但不甚明顯。However, the structure of the first bent portion 131 described above may become unnecessary if it is not used in a right angle adapter; for example, the first terminal 10' in the lower part of FIG. 2 and FIG. 4 can be used as an example. The third contact end portion 15' can be finally turned downwards, but is directly extended downward from the first extension portion 13' by the third neck portion 14'. Further, it can be found that the structural features of the first bent portion 131' exist, but are not obvious.
