Description
本發明涉及一種電連接器，尤其涉及一種電連接器的磁性元件的連接結構。 The present invention relates to an electrical connector, and more particularly to a connection structure of a magnetic component of an electrical connector.
適用於網路通訊的RJ45電連接器一般設置有磁性元件來達到濾波和防止電磁干擾的作用。此種電連接器安裝於外部電路板上並且還包括有絕緣本體及收容於絕緣本體的複數導電端子，絕緣本體設有對接面以供對接連接器插入，所述對接面一側定義為線纜端，外部電路板一側定義為物理端，電連接器線纜端與物理端之間設有複數傳輸通道，每一傳輸通道中連接有磁性元件，該磁性元件包括變壓器及共模扼流圈，每一傳輸通道中自線纜端先連接變壓器，然後連接共模扼流圈，最後連接至物理端；或者自線纜端先連接共模扼流圈，然後連接變壓器，最後連接至物理端。但是，每一傳輸通道的共模扼流圈位於電連接器同一側(即物理端或線纜端)，這樣會在傳輸通道之間產生信號串擾，不利於信號穩定傳輸。 RJ45 electrical connectors for network communication are typically provided with magnetic components to filter and prevent electromagnetic interference. The electrical connector is mounted on the external circuit board and further includes an insulative housing and a plurality of conductive terminals received in the insulative housing.

That is, the common mode choke 16 in the adjacent transmission channel is placed at different ends, so that signal crosstalk between the transmission channels can be reduced, and signal transmission is stabilized.
參第三圖所示，為本發明第二實施方式電路圖，與第一實施方式 相類似，在第二實施方式中，電連接器1也包括第一側a、與第一側相對的第二側b及位於第一側a與第二側b的複數傳輸通道。複數導電端子(J1至J8)位於第一側a用以與一對接連接器(未圖示)實現電性導通。第二側b則處於外部電路板一側。傳輸通道依次包括第一傳輸通道11、第二傳輸通道12、第三傳輸通道13及第四傳輸通道14，導電端子中的一對(例如J1和J2)組成一對差分信號端子連接至一傳輸通道內，另外，每一傳輸通道還連接有變壓器15及共模扼流圈16。其中，第一傳輸通道11及第三傳輸通道13中，變壓器15相較共模扼流圈16更靠近第一側a，即在電路連接中，自第一側a先連接變壓器15，再連接共模扼流圈16，最後連接至第二側b。第二傳輸通道12及第四傳輸通道14中，變壓器15相較共模扼流圈16更靠近第二側b，即在電路連接中，自第一側a先連接共模扼流圈16，再連接變壓器15，最後連接至第二側b。如此設置，可使相鄰傳輸通道的共模扼流圈16錯位排開(共模扼流圈16與變壓器15連接順序不同)，一傳輸通道中的共模扼流圈16靠近第一側a，另一傳輸通道中的共模扼流圈16靠近第二側b。即，相鄰傳輸通道中的共模扼流圈16擺放在不同端，如此可以減少傳輸通道之間的信號串擾，保證信號傳輸穩定。 Referring to FIG. 3, a circuit diagram of a second embodiment of the present invention, and a first embodiment Similarly, in the second embodiment, the electrical connector 1 also includes a first side a, a second side b opposite the first side, and a plurality of transmission channels at the first side a and the second side b. The plurality of conductive terminals (J1 to J8) are located on the first side a for electrically conducting with a pair of connectors (not shown). The second side b is on the side of the external circuit board. The transmission channel includes a first transmission channel 11, a second transmission channel 12, a third transmission channel 13, and a fourth transmission channel 14, and a pair of conductive terminals (for example, J1 and J2) constitute a pair of differential signal terminals connected to a transmission.

Wherein, in the first transmission channel 11 and the third transmission channel 13, the transformer 15 is closer to the first side a than the common mode choke coil 16, that is, in the circuit connection, the transformer 15 is first connected from the first side a, and then connected. The common mode choke 16 is finally connected to the second side b. In the second transmission channel 12 and the fourth transmission channel 14, the transformer 15 is closer to the second side b than the common mode choke coil 16, that is, in the circuit connection, the common mode choke coil 16 is connected from the first side a, The transformer 15 is reconnected and finally connected to the second side b. The arrangement is such that the common mode chokes 16 of the adjacent transmission channels are misaligned (the common mode choke 16 is connected to the transformer 15 in a different order), and the common mode choke 16 in a transmission channel is close to the first side a The common mode choke 16 in the other transmission channel is close to the second side b. That is, the common mode choke 16 in the adjacent transmission channel is placed at different ends, so that signal crosstalk between the transmission channels can be reduced, and signal transmission is stabilized.
當然，也可部分傳輸通道中的變壓器15(共模扼流圈16)靠近第一側a，其餘傳輸通道中的變壓器15(共模扼流圈16)靠近第二側b，同樣可以減少傳輸通道之間的信號串繞，保證信號傳輸穩定。 Of course, the transformer 15 (the common mode choke 16) in the partial transmission channel can also be close to the first side a, and the transformer 15 (the common mode choke 16) in the remaining transmission channels is close to the second side b, which can also reduce the transmission. The signal is wound around the channels to ensure stable signal transmission.
