Description
本發明係有關於一種電連接器技術領域，尤指一種在高速信號傳輸下仍具有良好穩定之電磁兼容性的電連接器結構。 The present invention relates to the technical field of electrical connectors, and in particular, to an electrical connector structure that still has good and stable electromagnetic compatibility under high-speed signal transmission.
隨著科技的蓬勃發展，各種電子產品接口之間訊號的傳輸速率一直是被重點研發的項目，因此早期的傳輸速率從USB1.0的1.5Mbps提升到近幾年USB3.2的最高20Gbps，甚至是新型的USB4最高能夠提升至40Gbps。 With the vigorous development of technology, the signal transmission rate between various electronic product interfaces has always been a key research and development project. Therefore, the early transmission rate has increased from 1.5Mbps of USB1.0 to the highest 20Gbps of USB3.2 in recent years, and even The new USB4 can increase up to 40Gbps.
另外，隨著各種電子產品邁向小型化，各種連接器必須在提高傳輸速率的情況下保有一定的大小，使得各種連接器在電磁屏蔽的結構上變得更加困難；且許多USB連接器的鐵殼會有縫隙或破孔而導致信號干擾。故如何設計讓連接器在高速信號的傳輸下，仍能夠具有良好穩定的電磁兼容性及避免信號干擾乃亟待改善之缺弊。 In addition, as various electronic products move toward miniaturization, various connectors must maintain a certain size while increasing the transmission rate, making the electromagnetic shielding structure of various connectors more difficult; and the iron of many USB connectors There may be gaps or holes in the shell that may cause signal interference. Therefore, how to design a connector so that it can still have good and stable electromagnetic compatibility and avoid signal interference under high-speed signal transmission is a shortcoming that needs to be improved urgently.
有鑑於此，本發明人遂針對上述現有技術的缺失，特潛心研究並配合學理的運用，盡力解決上述之問題點，即成為本發明人改良之目標。 In view of this, the inventor has devoted himself to research and applied academic theory to solve the above-mentioned problems in order to solve the above-mentioned deficiencies in the prior art, which has become the inventor's goal of improvement.
本發明之主要目的，在於在高速信號的傳輸下，仍能夠具有良好穩定之電磁兼容性的電連接器結構。 The main purpose of the present invention is to provide an electrical connector structure with good and stable electromagnetic compatibility under high-speed signal transmission.
為了達成上述之目的，本發明提供一種電連接器結構，包括一絕緣本體、複數導電端子、一屏蔽片及一屏蔽殼體，絕緣本體包括一基部及自基部延伸的一舌板，導電端子包括一上排端子及一下排端子，上排端子和下排端子係分別設於舌板的上下兩面，屏蔽片係埋設於絕緣本體內並位於上排端子及下排端子之間，屏蔽片的兩側分別延伸有穿出絕緣本體的一延伸段，且每一延伸段的末端反折形成有一卡合部，屏蔽殼體係套接包覆絕緣本體，屏蔽殼體的兩側分別設有一卡槽，各卡槽係套接卡固各卡合部而使屏蔽殼體和屏蔽片接觸。 In order to achieve the above object, the present invention provides an electrical connector structure, which includes an insulating body, a plurality of conductive terminals, a shielding sheet and a shielding shell. The insulating body includes a base and a tongue extending from the base. The conductive terminals include An upper row of terminals and a lower row of terminals. The upper row of terminals and the lower row of terminals are respectively provided on the upper and lower sides of the tongue plate. The shielding piece is embedded in the insulating body and is located between the upper row of terminals and the lower row of terminals. The two sides of the shielding piece There is an extension section extending out of the insulating body on each side, and the end of each extension section is folded to form an engaging portion. The shielding shell system is sleeved and covered with the insulating body, and a slot is provided on both sides of the shielding shell. Each clamping slot is sleeved and clamped to each engaging portion so that the shielding shell and the shielding piece are in contact.
本發明還具有以下功效：藉由反折成雙層的卡合部，可使結構增強避免變形或卡合力不足。透過導引斜面可提升卡合部在***卡槽時的順暢性。藉由卡槽上下兩側的凸塊，可讓凸塊與卡合部彼此干涉而穩固卡合不會鬆脫。透過讓位缺口可避免卡合部在***後，前端抵頂到卡槽的封閉端而影響組裝精度。藉由屏蔽殼體的接合處設置於舌板上方，使舌板下方的屏蔽殼體沒有破孔及間隙，而能保有良好的電磁遮蔽效果。透過外屏蔽殼可進一步地在屏蔽殼體頂部的接合處以及絕緣本體的末端做屏蔽，以強化絕緣本體上方及末端的電磁遮蔽效果。藉由各支撐凸塊可將電連接器支撐在印刷電路板上，以避免向前傾倒而達到支撐的效果。 The present invention also has the following effect: by folding back into a double-layered engaging portion, the structure can be strengthened to avoid deformation or insufficient engaging force. The guide slope can improve the smoothness of the engaging portion when inserted into the card slot. The bumps on the upper and lower sides of the slot allow the bumps and the engaging portion to interfere with each other and securely engage without loosening. The gap can be used to prevent the front end of the engaging portion from abutting the closed end of the slot after insertion, thereby affecting the assembly accuracy. By arranging the joint of the shielding shell above the tongue plate, the shielding shell below the tongue plate has no holes and gaps, and can maintain good electromagnetic shielding effect. Through the outer shielding shell, further shielding can be done at the joint at the top of the shielding shell and the end of the insulating body to enhance the electromagnetic shielding effect above and at the end of the insulating body. The electrical connector can be supported on the printed circuit board by each support bump to prevent it from falling forward and achieve the support effect.

有關本發明之詳細說明及技術內容，將配合圖式說明如下，然而所附圖式僅作為說明用途，並非用於侷限本發明。 The detailed description and technical content of the present invention will be described below with reference to the drawings. However, the attached drawings are only for illustrative purposes and are not intended to limit the present invention.
本發明係提供一種電連接器結構，請參照圖1至圖4所示，包括一絕緣本體10、複數導電端子20、一屏蔽片30及一屏蔽殼體40。
The present invention provides an electrical connector structure, as shown in FIGS. 1 to 4 , including an
絕緣本體10係由塑膠或其他絕緣的材料所製成。其主要包括一基部11以及自基部11延伸的一舌板12。舌板12為扁平狀的一板體。
The
導電端子20係以銅或其合金等導電性良好的材料所製成。其主要包括有一上排端子21及一下排端子22，且上排端子21和下排端子22係分別設置在舌板12的上下兩面。藉此舌板12能夠隔開上排端子21與下排端子22，避免兩者相接觸而影響訊號傳遞。
The
屏蔽片30係由金屬材料所製成的片狀結構。其係埋設在絕緣本體10內並位於上排端子21及下排端子22之間，並透過絕緣本體10來和上排端子21及下排端子22分隔避免直接接觸。藉此屏蔽片30可作為電子屏蔽，以避免上排端子21及下排端子22之間的信號互相干擾。在屏蔽片30的兩側分別延伸有穿出絕緣本體10的一延伸段31，且每一延伸段31的末端還反折形成有一卡合部32。
The shielding
於本實施例中，卡合部32係以延伸段31的末端朝遠離舌板12的方向朝下反折而形成的雙層結構，但發明不以此為限，例如延伸段31的末端也可以朝遠離舌板12的方向朝上反折、從外側朝絕緣本體10向內反折，或是藉由焊接或等其他方式來使卡合部32達到雙層的結構。
In this embodiment, the engaging
屏蔽殼體40係由金屬的片材彎折焊接所製成，其概呈橢圓狀的殼體。屏蔽殼體40係套接包覆絕緣本體10，並在兩側分別設有一卡槽41，各卡槽41係套接卡固於各卡合部32而使屏蔽殼體40和屏蔽片30接觸。藉此可讓屏蔽殼體40相對於上排端子21及下排端子22產生電磁屏蔽的作用。另外，由於卡合部32係透過延伸段31反折而形成，因此摺疊後的雙層厚度能夠增加卡合部32的結構強度，從而避免其與卡槽41在卡合時產生過度的變形或是卡合力不足而脫落的問題。
The shielding
進一步說明，請先參閱圖5所示。在卡槽41的開口處分別形成有一導引斜面411，藉此可提升卡合部32在***卡槽41時的順暢性。且卡槽41內的上下兩側還分別凸設有一凸塊412。藉此可讓卡合部32在***卡槽41時，各凸塊412能夠與卡合部32彼此達到干涉，以使兩者穩固卡合不會鬆脫，從而確保屏蔽片30與屏蔽殼體40之間保持接觸。又，請接著參閱圖6。在卡槽41的封閉端還形成有一讓位缺口413。由於卡合部32在反折時長度會存在有一定的公差，因此讓位缺口413可用於避免卡合部32在***後，卡合部32的前端抵頂到卡槽41的封閉端，從而影響組裝精度。
For further explanation, please refer to Figure 5. A
復參閱圖5及圖6所示，係本發明屏蔽殼體40的裝設示意圖。首先將屏蔽殼體40套覆絕緣本體10，並將兩側的卡槽41對準各卡合部32，此時卡槽41開口處的導引斜面411能夠方便卡合部32***，如圖5。接著將卡合部32***卡槽41內進行卡固，透過各凸塊412能夠讓卡合部32與卡槽41緊密卡合，讓位缺口413則能夠避免卡合部32的前端抵推到屏蔽殼體40造成組裝誤差，如圖6。
Referring back to FIG. 5 and FIG. 6 , it is a schematic diagram of the installation of the shielding
特別說明，復參閱圖1及圖2所示。本發明之電連接器結構的屏蔽殼體40係將金屬片材的兩側向上彎折成一殼體，並形成有一接合處42。因此屏蔽殼體40的接合處42係位在舌板12的上方，使得舌板12下方的屏蔽殼體40沒有破孔及間隙，從而能夠保有良好的電磁遮蔽效果。
For special instructions, please refer to Figures 1 and 2. The shielding
又，本發明之電連接器結構還包括有一外屏蔽殼50。外屏蔽殼50係由金屬的片材彎折所製成，其概呈倒U字型的蓋體。外屏蔽殼50係自屏蔽殼體40的上方罩設包覆並且遮蔽住接合處42，且外屏蔽殼50的尾端還彎折有一後蓋51，後蓋51係遮擋住絕緣本體10遠離舌板12的一端。藉此可進一步地在屏蔽殼體40頂部的接合處42以及絕緣本體10的末端做屏蔽，以強化絕緣本體10上方及末端的電磁遮蔽效果。
Furthermore, the electrical connector structure of the present invention further includes an
特別說明，於本實施例中，各卡槽41係形成在屏蔽殼體40的兩側。但本發明不以此為限，例如各卡槽41也可以形成在外屏蔽殼50的兩側，並分別與屏蔽片30的卡合部32相卡固而達到電磁屏蔽的效果。此僅為本發明的具通常知識者可易於思及的簡單變形，故不論卡合部32係形成在屏蔽殼體40或外屏蔽殼50上，都應在本發明的保護範圍內。
Specifically, in this embodiment, each
進一步說明，請參閱圖2及8所示。絕緣本體10的底部朝舌板12的延伸方向凸設有複數定位塊13，屏蔽殼體40的底部形成有對應各定位塊13的複數定位槽43，各定位塊13係對應各定位槽43卡設定位。藉此可確保屏蔽殼體40與絕緣本體10在組裝時，兩者之間能夠裝設到定位。接著請參閱圖7及圖8，係本發明屏蔽殼體40與絕緣本體10組裝後不同視角的外觀圖。
For further explanation, please refer to Figures 2 and 8. A plurality of positioning blocks 13 are protruding from the bottom of the insulating
復參閱圖1，絕緣本體10的頂部開設有複數扣槽14，屏蔽殼體40的頂部則設有複數扣臂44。請再參閱圖7所示，當屏蔽殼體40套接包覆於絕緣本體10，且卡合部32卡固於卡槽41內後，各扣臂44可向下扣設於各扣槽14內，藉以進一步地將屏蔽殼體40固定，從而避免自絕緣本體10上脫落。
Referring again to FIG. 1 , the top of the insulating
又，請參閱圖2、6及8所示。屏蔽殼體40的底部還形成有複數支撐凸塊45，各支撐凸塊45係概呈圓形的凸塊。其係屏蔽殼體40的金屬片材在彎折形成殼體前，透過拉伸成型所製成。復參閱圖1及圖2所示，屏蔽殼體40及外屏蔽殼50皆形成有複數焊腳46、52。並接著請參閱圖9所示，係本發明應用於印刷電路板A時的使用狀態圖。各焊腳46、52係穿設於印刷電路板A以焊接固定，而各支撐凸塊45則可以支撐在印刷電路板A上，以避免整個電連接器向前傾倒，從而達到支撐的效果。而相較於習知的技術，一般設計係在焊腳的前端形成有一支撐台階，使得各焊腳焊接固定於印刷電路板上時，可透過支撐台階來支撐而不會傾倒；但由於不同印刷電路板的塗料厚度不一，因此會使得電連接器相對應的被抬起或傾斜，故本發明電連接器的各支撐凸塊亦可有效改善此缺弊，達到能夠適用於各種不同印刷電路板的效果。
Also, please refer to Figures 2, 6 and 8. A plurality of support bumps 45 are also formed on the bottom of the shielding
綜上所述，本發明已具有產業利用性、新穎性與進步性，完全符合專利申請要件，爰依專利法提出申請。當然，本發明還可有其他多種實施例，在不背離本發明精神及其實質的情況下，熟悉本領域的技術人員當可根據本發明演化出各種相應的改變和變形，但這些相應的改變和變形都應屬於本發明所申請專利的保護範圍。 To sum up, the present invention has industrial applicability, novelty and advancement, fully meets the requirements for patent application, and the application can be filed in accordance with the patent law.
