Description
本發明涉及一種電連接器，尤其涉及一種具有金屬外殼之電連接器。 The present invention relates to an electrical connector, and more particularly to an electrical connector having a metal outer casing.
通用串列匯流排(Universal Serial Bus,USB)界面作為一種標準之輸入/輸出界面，已被廣泛應用於眾多電子設備中。1994年，英代爾、康柏、數字、IBM、微軟、NEC、Northern Telecom等7家世界著名之電腦和通信公司聯合成立了USB協會(USB-IF)，初步設立USB界面規範。到目前為止，USB協會已經發佈了1.0、1.1及2.0等版本。 As a standard input/output interface, the Universal Serial Bus (USB) interface has been widely used in many electronic devices. In 1994, seven world-renowned computer and communication companies, including Intel, Compaq, Digital, IBM, Microsoft, NEC, and Northern Telecom, jointly established the USB Association (USB-IF) to initially establish a USB interface specification. So far, the USB Association has released versions 1.0, 1.1 and 2.0.
上述USB 1.0、1.1、2.0版本分別支持下述三種傳輸速率：(1)、低速模式傳輸速率為1.5兆比特每秒，多用於鍵盤和滑鼠；(2)、全速模式傳輸速率為12兆比特每秒；(3)、高速模式傳輸速率為480兆比特每秒。 The above USB 1.0, 1.1, and 2.0 versions support the following three transmission rates: (1), low-speed mode transmission rate of 1.5 megabits per second, mostly for keyboards and mice; (2), full-speed mode transmission rate of 12 megabits (3), high-speed mode transmission rate is 480 megabits per second.
然而，即使是USB 2.0，其傳輸速率已經不能滿足某些需求，2008年年底，USB協會發佈了3.0版本之USB標準，USB 3.0之傳輸速率可達到5Gbps。 However, even with USB 2.0, the transfer rate is no longer sufficient. At the end of 2008, the USB Association released the 3.0 standard USB standard, and the USB 3.0 transfer rate can reach 5Gbps.
隨著電子工業之進一步發展，如今消費者對大容量資料傳輸速率 具有更高之需求，需要基於USB 3.0標準進一步提高傳輸速率，並且新規格中之電連接器也能與符合先前之USB設備(也稱為：向後相容)。 With the further development of the electronics industry, today's consumers have a large data transmission rate. With higher demands, it is necessary to further increase the transmission rate based on the USB 3.0 standard, and the electrical connector in the new specification can also be compatible with the previous USB device (also known as backward compatibility).
與本發明相關之習知技術可參閱2007年2月21日公告之台灣專利第M306726號所揭示之一種電連接器，該電連接器包括絕緣本體、設於絕緣本體上之複數導電端子及覆蓋於絕緣本體外側之遮蔽殼體。所述絕緣本體包括主體部、自主體部向前延伸之舌板及安裝於主體部後端之定位座，所述導電端子包括固持於主體部之固持部、自固持部向前延伸入舌板之接觸部、自固持部後端向下垂直延伸收容於所述定位座內之延伸部及自延伸部向下延伸出所述定位座之焊接部，所述遮蔽殼體包括頂壁、與頂壁相對之底壁、連接頂壁與底壁之兩側壁、自頂壁後端向下垂直延伸之後蓋及由頂壁、底壁及兩側壁圍設成之一收容空間，所述遮蔽殼體之側壁前端設有向下豎直延伸之固持腳，所述後蓋兩側設有向下豎直延伸之安裝腳，用以與電路板連接以形成接地回路。所述後蓋在絕緣本體未安裝時與遮蔽殼體之頂壁位於同一水平面上，即，所述安裝腳與所述頂壁位於同一水平面上，所述絕緣本體自後向前安裝於收容空間內後，再將所述後蓋向下彎折覆蓋於所述絕緣本體之定位座之後端，在該連接器傳輸速率與USB 3.0訊號傳輸速率相同時，端子之間產生串擾訊號足以通過安裝腳導出，從而不會影響連接器之傳輸速率或造成端子之間的訊號干擾。然而，當連接器之傳輸速率提高至USB 3.0訊號傳輸速率之兩倍時，導電端子產生之大量串擾訊號堆積在後蓋與定位座之間的間隙內，產生大量輻射，所述固持腳與安裝腳無法及時將串繞訊號接地導出，從而影響電連接器之傳輸速率，為提高固持腳與安裝腳之接地效 果，需要將連接器之外殼先整體進行鍍鎳後，再將固持腳與安裝腳進行鍍金處理，當對固持腳進行鍍金處理時，將連接器之遮蔽殼體向下豎直放入鍍金池內，再給安裝腳鍍金時需要將連接器豎直翻轉，以將安裝腳豎直向下放入鍍金池內，無法同時將固持腳與安裝腳同時鍍金，造成製造過程複雜。 An electrical connector disclosed in Taiwan Patent No. M306726, which is hereby incorporated by reference in its entirety, the entire disclosure of which is incorporated herein by reference. a shielding shell outside the insulating body. The insulative housing includes a main body portion, a tongue plate extending forward from the main body portion, and a positioning seat mounted on the rear end of the main body portion. The conductive terminal includes a holding portion that is retained on the main body portion, and extends from the holding portion to the tongue plate. The contact portion and the rear end of the self-retaining portion extend vertically downwardly from the extending portion of the positioning seat and the extending portion of the positioning seat downwardly extending from the extending portion, the shielding housing including the top wall and the top portion a cover wall opposite to the bottom wall, connecting the two side walls of the top wall and the bottom wall, and extending downward from the rear end of the top wall, and a cover space surrounded by the top wall, the bottom wall and the two side walls, the shielding shell The front end of the side wall is provided with a holding leg extending vertically downward, and the rear cover is provided with mounting legs extending vertically downwards for connecting with the circuit board to form a ground loop. The back cover is located on the same horizontal plane as the top wall of the shielding shell when the insulating body is not installed, that is, the mounting leg and the top wall are on the same horizontal plane, and the insulating body is installed in the receiving space from the back to the front. After the inner cover, the rear cover is bent downward to cover the rear end of the positioning base of the insulative housing. When the transmission rate of the connector is the same as the USB 3.0 signal transmission rate, a crosstalk signal is generated between the terminals through the mounting foot. Export, so as not to affect the transmission rate of the connector or cause signal interference between the terminals. However, when the transmission rate of the connector is increased to twice the transmission rate of the USB 3.0 signal, a large amount of crosstalk signals generated by the conductive terminals are accumulated in the gap between the back cover and the positioning seat, generating a large amount of radiation, and the holding legs are mounted. The foot cannot be grounded in time to ground the signal, thereby affecting the transmission rate of the electrical connector, in order to improve the grounding effect of the holding foot and the mounting foot. If the outer shell of the connector is first nickel-plated, then the holding leg and the mounting foot are gold-plated. When the holding foot is gold-plated, the shielding shell of the connector is vertically placed into the gold-plated pool. Inside, when the mounting feet are gold-plated, the connector needs to be turned upside down so that the mounting feet are vertically placed in the gold-plated pool, and the holding legs and the mounting feet cannot be simultaneously plated with gold, which complicates the manufacturing process.
綜上所述，有必要針對現有電連接器進行改良以克服上述缺陷。 In summary, it is necessary to modify existing electrical connectors to overcome the above drawbacks.
鑒於上述內容，本發明之目的在於提供一種製造方便之電連接器。 In view of the above, it is an object of the present invention to provide an electrical connector that is easy to manufacture.
