Electric connector and circuit board applied to connector

Abstract

The invention discloses an electric connector and a circuit board applied to the connector, the electric connector comprises an insulation body and a terminal module contained in the insulation body, the terminal module comprises the circuit board and first to eighth terminals which are sequentially arranged in the transverse direction and electrically connected to the circuit board, wherein the third terminal and the sixth terminal transmit a pair of differential signals, the fourth terminal and the fifth terminal transmit the other pair of differential signals, the circuit board is provided with first to eighth conductive traces electrically connected with the corresponding first to eighth terminals respectively, and the third conductive trace and the fifth conductive trace both comprise coupling parts. The transverse size of the coupling part is larger than the transverse size of other parts of the conductive traces, and the coupling part of the third conductive trace and the coupling part of the fifth conductive trace are over against each other in the vertical direction so as to increase the coupling between the third conductive trace and the fifth conductive trace. The electric connector can effectively reduce crosstalk interference in the connector and is simple in structure.

Description

【Technical field】 [0001] The invention relates to an electrical connector and a circuit board used in the connector, in particular to an electrical connector capable of reducing crosstalk interference between signal transmission paths and the circuit board in the connector. 【Background technique】 [0002] As the speed of data transmission continues to increase, how to reduce or eliminate crosstalk in the electrical connector becomes very important. In the prior art, the RJ45 connector has 8 terminals to form four channels, in which the third terminal and the sixth terminal form the second channel to transmit a pair of differential signals, and the fourth terminal and the fifth terminal form the third channel to transmit a pair of differential signals. Signal, the fourth terminal and the fifth terminal are sandwiched between the third terminal and the sixth terminal, resulting in crosstalk interference among the eight conductive terminals between the four terminals in the sec...

Problems solved by technology

In order to increase the balance, the value of b increases by approaching the third terminal and the fifth terminal laterally, so that the value of (a-b) decreases, but by the lateral approach of the third terminal and the fifth terminal, the fourth terminal and the sixth terminal Laterally close to increase the capacitive coupling effect between the third terminal and the fifth terminal and the fourth terminal and the sixth terminal to balance the crosstalk interference caused by their distance, so that the terminal structure overlaps and the terminal structure is complicated. Difficult to manufacture and expensive
