Description
本新型係關於一種連接器,尤指一種抑制訊號干擾的插座電連接器,其可有效抑制訊號端子之間的串音干擾(Crosstalk)。The present invention relates to a connector, and more particularly to a socket electrical connector for suppressing signal interference, which can effectively suppress crosstalk between signal terminals.
大型的電腦伺服器,諸如刀鋒伺服器(Blade server)、機架式伺服器(Rack Mount Server)等等,其內部的電路板上大量設置有高速的電連接器,這些電連接器通常具有密集排列的複數端子以便能夠快速傳輸大量訊號。然而,電連接器的訊號端子之間時常產生串音干擾的問題,而串音干擾在訊號端子傳輸高頻訊號的狀況下尤為明顯,造成訊號傳輸的效率下降,甚至造成訊號傳輸中斷。Large computer servers, such as Blade servers, Rack Mount Servers, etc., have a large number of high-speed electrical connectors on their internal boards. These connectors are usually dense. Arrange multiple terminals to enable fast transmission of large numbers of signals. However, the problem of crosstalk interference often occurs between the signal terminals of the electrical connector, and the crosstalk interference is particularly obvious when the signal terminal transmits the high frequency signal, which causes the efficiency of the signal transmission to decrease, and even causes the signal transmission to be interrupted.
請參照圖12,為了避免上述串音干擾,有人發展出一種改良的電連接器,該電連接器包含有複數並排設置的絕緣板90,在各絕緣板90上分別設置有複數端子91,在兩相鄰絕緣板90之間分別放置一金屬屏蔽片92,使得金屬屏蔽片92與絕緣板90相互間隔排列,以令各金屬屏蔽片92位於兩組端子91之間。透過上述配置可阻絕各金屬屏蔽片92兩側的兩組端子91間的訊號干擾。然而,由於金屬屏蔽片92本身為一完整且具有一定長度與寬度的片體,容易提供一定長度的路徑供電荷流竄,造成天線效應, 導致產生另外的訊號干擾,例如,金屬屏蔽片92的斜對角路徑P0為最長的長度,可輕易的造成天線效應。Referring to FIG. 12, in order to avoid the above-mentioned crosstalk interference, an improved electrical connector has been developed. The electrical connector includes a plurality of insulating plates 90 arranged side by side, and a plurality of terminals 91 are respectively disposed on the insulating plates 90. A metal shielding piece 92 is disposed between the two adjacent insulating plates 90, so that the metal shielding piece 92 and the insulating plate 90 are spaced apart from each other such that the metal shielding pieces 92 are located between the two sets of terminals 91. Through the above configuration, signal interference between the two sets of terminals 91 on both sides of each metal shielding sheet 92 can be blocked. However, since the metal shielding sheet 92 itself is a complete sheet having a certain length and width, it is easy to provide a path of a certain length for the charge to flow, resulting in an antenna effect. This causes additional signal interference. For example, the oblique diagonal path P0 of the metal shield 92 is the longest length, which can easily cause an antenna effect.
若是能在上述金屬屏蔽片92上採取截斷路徑的措施,則可有效縮短造成天線效應的路徑,然而,目前並沒有人在金屬屏蔽片92做出任何截斷路徑的措施。下列的先前技術雖然在電連接器的屏蔽片或是類似元件上做出改良,惟這些改良均非針對截斷路徑,以致於沒有達到防止訊號干擾的目的。If the cutting path can be taken on the above-mentioned metal shielding piece 92, the path causing the antenna effect can be effectively shortened. However, no one has made any cutting path on the metal shielding piece 92 at present. Although the following prior art has been improved on the shield or the like of the electrical connector, these improvements are not directed to the cut-off path, so that the purpose of preventing signal interference is not achieved.
請參照美國第7,347,740號專利案,其揭露一種電連接器的導線架組件,其中各端子上形成有做為固定用的固定孔,而介電材料以射出成型方式包覆端子的局部並且填充於前述固定孔之中,惟該案不具屏蔽板的結構,且端子固定孔僅作為輔助將介電材料固定在導線架組件的用途,並非作為防止串音干擾的用途。Please refer to U.S. Patent No. 7,347,740, which discloses a lead frame assembly of an electrical connector in which a fixing hole for fixing is formed on each terminal, and a dielectric material is covered by a portion of the terminal in an injection molding manner and filled in Among the aforementioned fixing holes, the case does not have the structure of the shielding plate, and the terminal fixing hole serves only as an auxiliary for fixing the dielectric material to the lead frame assembly, and is not intended to prevent crosstalk interference.
請參照美國第7,074,086號專利案,其在實施方式中提到同一申請人擁有的美國第6,409,543號專利案,在該案中揭露一屏蔽片,該屏蔽片上貫穿形成複數穿孔,惟該複數穿孔主要在組裝過程中,供一工具穿過,以斷開端子間的固定條,而非作為防止串音干擾的用途。Reference is made to U.S. Patent No. 7,074,086, the disclosure of which is incorporated herein by reference in its entirety in the entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire all During the assembly process, a tool is passed through to break the fixing strip between the terminals instead of being used as a crosstalk prevention.
美國第8,182,289號專利案揭露一種電連接器,其有損置入片(Lossy Insert)上貫穿形成複數穿孔以便與端子的固定架上的固定柱相互組裝,該複數穿孔非作為防止串音干擾的用途。U.S. Patent No. 8,182,289 discloses an electrical connector in which a plurality of perforations are formed through a Loss Insert to be assembled with a mounting post on a mounting bracket of a terminal that does not interfere with crosstalk. use.
簡言之,目前尚無人對電連接器的屏蔽片做出有效的截斷路徑措施,訊號干擾的問題仍存在。In short, there is no effective cut-off path for the shield of the electrical connector, and the problem of signal interference still exists.
本新型創作人有鑑於目前電連接器在屏蔽片上均未採取截斷路徑的措施而容易導致天線效應的缺點,改良其不足與缺失,進而新型出一種抑制訊號干擾的插座電連接器。In view of the fact that the current connector does not take a cut-off path on the shielding piece, the creator of the present invention easily causes the shortcoming of the antenna effect, improves the deficiency and the lack thereof, and further introduces a socket electrical connector that suppresses signal interference.
本新型主要目的係提供一種抑制訊號干擾的插座電連接器,其可有效抑制訊號端子之間的串音干擾(又稱串擾,Crosstalk)。The main purpose of the present invention is to provide a socket electrical connector for suppressing signal interference, which can effectively suppress crosstalk interference (also known as crosstalk) between signal terminals.

請參照圖1到圖3,本新型抑制訊號干擾的插座電連接器可以焊接方式固定在一電路板上,且包含有:複數絕緣板體10、複數端子組、複數屏蔽板30、一外殼40以及一後組裝蓋50。Referring to FIG. 1 to FIG. 3 , the socket electrical connector for suppressing signal interference can be soldered to a circuit board, and includes: a plurality of insulating plate bodies 10 , a plurality of terminal groups, a plurality of shielding plates 30 , and a casing 40 . And assembling the cover 50 one after the other.
請進一步參照圖4到圖6,該複數絕緣板體10係以相並排方式排列。各絕緣板體10上形成有複數第一結合元件12、13。4 to 6, the plurality of insulating plates 10 are arranged side by side. A plurality of first coupling members 12, 13 are formed on each of the insulating sheets 10.
該複數端子組係分別設置在該複數絕緣板體 10內,各端子組包含有複數訊號端子20s與複數接地端子20g。此外,各訊號端子20s或接地端子20g係包含一固定段21、一組裝段22以及一電性接觸段23。該固定段21係埋設在對應的絕緣板體10內。該組裝段22係自固定段21向下延伸,且供焊接段或是壓接沖壓而固定在一電路板上。該電性接觸段23係自固定段21朝前突伸,可為叉狀。The plurality of terminal groups are respectively disposed on the plurality of insulating plates In 10, each terminal group includes a plurality of signal terminals 20s and a plurality of ground terminals 20g. In addition, each of the signal terminals 20s or the ground terminals 20g includes a fixed section 21, an assembly section 22, and an electrical contact section 23. The fixing section 21 is embedded in the corresponding insulating plate body 10. The assembly section 22 extends downwardly from the fixed section 21 and is attached to a circuit board for soldering or crimping. The electrical contact section 23 protrudes forward from the fixing section 21 and may be fork-shaped.
請進一步參照圖7到圖9,該複數屏蔽板30係分別設置在該複數絕緣板體10的一側,且作為防止串音干擾的用途,各屏蔽板30上貫穿形成有複數電流路徑阻斷孔300,各電流路徑阻斷孔300保持空洞狀態而非供其他物體穿過,且各屏蔽板30與相對應端子組中的接地端子20g相連接。Referring to FIG. 7 to FIG. 9 , the plurality of shielding plates 30 are respectively disposed on one side of the plurality of insulating plates 10 , and as a purpose of preventing crosstalk interference, a plurality of current path blocking is formed on each shielding plate 30 . In the hole 300, each current path blocking hole 300 is kept in a hollow state instead of being passed through by other objects, and each of the shield plates 30 is connected to the ground terminal 20g in the corresponding terminal group.
根據天線效應,如屏蔽板30般的暴露金屬塊體容易具有天線的特性,會蒐集電荷而使其電位升高,並且造成電流,而電流容易沿著金屬塊體上具有充分長度的路徑流竄,造成高頻或低頻訊號干擾,而金屬塊體上又以沿著對角線的路徑為最長。因此,在各屏蔽板30上貫穿形成電流路徑阻斷孔300,對角線的長度被縮短到相鄰電流路徑阻斷孔300之間的間距長度,藉此可減少甚至阻絕電流路徑,藉此能有效縮短各屏蔽板30的天線效應。如圖9所示任兩相鄰電流路徑阻斷孔300的邊緣之間的間距P1一般而言0.9mm以下,遠小於屏蔽板30的斜對角長度,此外,靠近各該屏蔽板30的周緣的各該電流路徑阻斷孔300的邊緣與該屏蔽板的周緣之間的間距P2為1mm以下,藉此可有效降低天線效應。According to the antenna effect, the exposed metal block such as the shield plate 30 easily has the characteristics of the antenna, collects charges to increase its potential, and causes current, and the current easily flows along a path having a sufficient length on the metal block. Causes high frequency or low frequency signal interference, and the metal block has the longest path along the diagonal line. Therefore, the current path blocking holes 300 are formed through the shield plates 30, and the length of the diagonal lines is shortened to the length of the pitch between the adjacent current path blocking holes 300, whereby the current path can be reduced or even blocked. The antenna effect of each shielding plate 30 can be effectively shortened. The spacing P1 between the edges of any two adjacent current path blocking holes 300 as shown in FIG. 9 is generally 0.9 mm or less, which is much smaller than the diagonally opposite length of the shielding plate 30, and further, close to the periphery of each of the shielding plates 30. The pitch P2 between the edge of each of the current path blocking holes 300 and the periphery of the shield plate is 1 mm or less, whereby the antenna effect can be effectively reduced.
此外,各屏蔽板30上形成有至少一與相對應絕緣板體10的相對應第一結合元件12、13相結合的第二結合元件32、33。Further, at least one second coupling member 32, 33 combined with the corresponding first coupling member 12, 13 of the corresponding insulating plate body 10 is formed on each of the shielding plates 30.
該外殼40係覆蓋於所有的絕緣板體10外以組合絕緣板體10。此外,該外殼40前端41係貫穿形成複數插接口410以分別供訊號端子20s或接地端子20g的電性接觸段23設置於相對應插接口410內。The outer casing 40 covers all of the insulating plate bodies 10 to combine the insulating plate bodies 10. In addition, the front end 41 of the casing 40 is formed through the plurality of plug connectors 410 to be respectively disposed in the corresponding plug connectors 410 for the electrical contact segments 23 of the signal terminals 20s or the ground terminals 20g.
該後組裝蓋50結合於所有絕緣板體10的後端以便確保絕緣板體10能夠精確地並排組合。The rear assembled cover 50 is bonded to the rear ends of all the insulating plate bodies 10 to ensure that the insulating plate bodies 10 can be accurately combined side by side.
於本案較佳實施例之中,各第一結合元件12、13為凹槽或是凸塊;各第二結合元件32、33為對應第一結合元件12、13之凸塊或是凹槽。In the preferred embodiment of the present invention, each of the first bonding elements 12, 13 is a groove or a bump; and each of the second bonding elements 32, 33 is a bump or a groove corresponding to the first bonding component 12, 13.
於本案較佳實施例之中,各屏蔽板30上形成有一第一連接元件35,該第一連接元件35可以是一扣片;各端子組中與相對應屏蔽板30相連接的接地端子20g上形成有與第一連接元件35連接的第二連接元件25,該第二連接元件25可以是一與對應扣片相扣合的扣孔。此外,各該絕緣本體10上形成有複數破孔15以分別供第一連接元件35穿過對應破孔15而連接第二元件25。In the preferred embodiment of the present invention, a first connecting component 35 is formed on each shielding plate 30. The first connecting component 35 can be a buckle; the grounding terminal 20g of each terminal group connected to the corresponding shielding plate 30. A second connecting element 25 is formed on the first connecting element 35. The second connecting element 25 can be a fastening hole that is engaged with the corresponding fastening piece. In addition, a plurality of holes 15 are formed in each of the insulating bodies 10 for respectively connecting the first connecting elements 35 through the corresponding holes 15 to connect the second elements 25.
請進一步參照圖10,本新型創作人對於訊號端子20s的訊號進行測試,從插接口410方向觀看,將端子20編列為第A到I列與第1到6排,針對各兩兩相鄰的端子20進行串音干擾測試,例如對座標(A,3)與(B,3)(座標以下縮寫為AB3)的兩訊號端子20s進行測試。未採用屏蔽板30與採用屏蔽板30測試比對表如下:
上述比對表可知,大部分訊號端子20s的在配合屏蔽板30之後,串音干擾程度均有下降,進而能增進訊號端子20s的訊號傳輸效率與穩定。As can be seen from the above comparison table, the crosstalk interference level of most of the signal terminals 20s after the shield plate 30 is matched is reduced, thereby improving the signal transmission efficiency and stability of the signal terminal 20s.
請進一步參照圖11,於本新型另一實施例之中,各該屏蔽片30a不與任一訊號端子20s或接地端子20g'相連接,故各該屏蔽片30a不具有第一連接元件,且各該訊號端子20s或接地端子20g'不具有第二連接元件。然而, 各該屏蔽片30a仍具有第二結合元件32、33以結合絕緣板體10的第一結合元件12、13。With reference to FIG. 11 , in another embodiment of the present invention, each of the shielding sheets 30 a is not connected to any of the signal terminals 20 s or the ground terminals 20 g ′, so that each of the shielding sheets 30 a does not have the first connecting elements, and Each of the signal terminals 20s or the ground terminals 20g' does not have a second connecting element. however, Each of the shielding sheets 30a still has second coupling members 32, 33 to bond the first coupling members 12, 13 of the insulating plate body 10.
藉由上述技術手段,本新型具有下列優點:With the above technical means, the present invention has the following advantages:
1.由於各絕緣板體10一側均設置有一屏蔽板30,使得端子組與屏蔽板30呈現交錯配置,故相鄰的端子組之間的串音干擾程度大為降低。1. Since one shielding plate 30 is disposed on one side of each insulating plate body 10, the terminal group and the shielding plate 30 are arranged in a staggered configuration, so the degree of crosstalk interference between adjacent terminal groups is greatly reduced.
2.各屏蔽板30具有複數電流路徑截斷孔300,可減少甚至排除屏蔽板30的天線效應,能夠令屏蔽板30進一步大幅抑制串擾,藉此增進訊號端子20s的訊號傳輸效率與穩定性。2. Each of the shielding plates 30 has a plurality of current path intercepting holes 300, which can reduce or even eliminate the antenna effect of the shielding plate 30, and can further significantly suppress the crosstalk of the shielding plate 30, thereby improving the signal transmission efficiency and stability of the signal terminal 20s.
3.屏蔽板30的第一連接元件35與接地端子20g的第二連接元件25相連而使得屏蔽板30能透作為接地端子20g的延伸,擴大接地效用,將靜電與可能導致串擾的雜訊導出電連接器之外,進而提高訊號傳輸的效率與穩定性。3. The first connecting element 35 of the shielding plate 30 is connected to the second connecting element 25 of the grounding terminal 20g so that the shielding plate 30 can penetrate as an extension of the grounding terminal 20g, thereby expanding the grounding effect, and discharging static electricity and noise which may cause crosstalk. In addition to the electrical connector, the efficiency and stability of signal transmission are improved.
