Description

電連接器 Electrical connector

本創作涉及一種電連接器，尤其涉及一種電連接器之端子結構及佈置設計。 The present invention relates to an electrical connector, and more particularly to a terminal structure and arrangement design of an electrical connector.

在高頻RJ45電連接器中，RJ45電連接器的差分訊號對端子間容易產生串擾。一項日益突出的問題係隨著傳輸頻率的增高(增加有效通訊資料的傳輸速度)而產生出的串擾問題尤其嚴重。先前技術請參閱2006年2月7日公告的美國US6,994,594專利。該專利揭示了將一對差分訊號對與另外三對差分訊號向相反方向延伸，達成電流向相反方向傳輸，達成降低差分訊號對之間的串擾。 In the high-frequency RJ45 electrical connector, the differential signal of the RJ45 electrical connector is prone to crosstalk between the terminals. An increasingly prominent problem is the crosstalk problem that arises with increasing transmission frequencies (increasing the transmission speed of effective communication data). For prior art, please refer to U.S. Patent No. 6,994,594 issued on Feb. 7, 2006. The patent discloses that a pair of differential signal pairs and three other pairs of differential signals are extended in opposite directions to achieve current transmission in opposite directions, thereby achieving crosstalk between the reduced differential signal pairs.

藉如是排配的RJ45電連接器，由於端子安裝到外部電路板上的安裝部設有控制安裝部***深度的凸塊，不便於焊接，且即使焊接到外部電路板上後，由於端子與對接端子的重複插拔，容易引起焊點的脫落，導致連接不良。因此，有必要對現有結構進行改進設計。 In the case of the RJ45 electrical connector, since the mounting portion of the terminal mounted on the external circuit board is provided with a bump for controlling the insertion depth of the mounting portion, it is inconvenient to solder, and even after soldering to the external circuit board, the terminal and the docking are performed. Repeated insertion and removal of the terminals may cause the solder joints to fall off, resulting in poor connection. Therefore, it is necessary to improve the design of existing structures.

本創作所要解決的技術問題係：提供一種焊接方便、保護端子焊點且能降低差分訊號對端子間串擾的RJ45電連接器。 The technical problem to be solved by this creation is to provide an RJ45 electrical connector that is convenient for soldering, protects the terminal solder joints, and reduces the crosstalk between the differential signals and the terminals.

為解決上述問題，本創作提供一種電連接器，包括絕緣本體；及安裝於絕緣本體內的端子模組，所述端子模組包括固持件及固持於固持件的複數導電端子，所述複數導電端子包括第一端子組與第二端子組，第一端子組具有第一接觸部、自第一接觸部向前延伸的第一連接部，第二端子組具有第二接觸部、自第二接觸部向後延伸的第二連接部，所述第一接觸部與第二接觸部並列排佈；所述第二端子還設有第二尾部以及位於第二尾部與第二連接部之間的第二固持部，固持件設有位於第二尾部與第二固持部之間的豎直壁，第二固持部抵靠於所述豎直壁的前側。 In order to solve the above problems, the present invention provides an electrical connector including an insulative housing; and a terminal module mounted in the insulative housing, the terminal module including a holding member and a holding a plurality of conductive terminals of the holder, the plurality of conductive terminals including a first terminal group and a second terminal group, the first terminal group having a first contact portion, a first connection portion extending forward from the first contact portion, and a second The terminal group has a second contact portion, a second connecting portion extending rearward from the second contact portion, the first contact portion and the second contact portion are arranged side by side; the second terminal is further provided with a second tail portion and is located at the a second holding portion between the two tail portions and the second connecting portion, the holding member is provided with a vertical wall between the second tail portion and the second holding portion, and the second holding portion abuts against the front side of the vertical wall.

相較於先前技術，本創作藉由一固持件將端子結合在一起，固持件可控制端子的***深度，焊接方便且能保護端子焊點。第一接觸部、第二接觸部沿相反兩個方向傳輸電流能降低第一端子組、第二端子組間的串擾(crosstalk)。 Compared with the prior art, the present invention combines the terminals by a holding member, and the holding member can control the insertion depth of the terminal, and the welding is convenient and can protect the terminal solder joint. The first contact portion and the second contact portion transmit current in opposite directions to reduce crosstalk between the first terminal group and the second terminal group.
