Description

Technical Field

[0001] The present invention relates to the technical field of RJ45 connectors, and more particularly to an RJ45 connector with laminated terminals. Background Art

[0002] RJ45 connection is the current standard device for Ethernet connection interface, and is widely used in Ethernet cards, routers, switches and other network products. With the increase of transmission speed and frequency, return loss, characteristic impedance and crosstalk have become the primary issues restricting its development. The competition for miniaturization of electronic equipment is becoming more and more fierce, and the network interface part has also been optimized in structure to reduce the space occupied.

[0003] The terminals of the existing RJ45 connector are designed to be evenly arranged horizontally. At this time, the degree of coupling between the terminals is relatively large, and the mutual inductance and mutual capacitance between the signal lines can easily cause an increase in noise on the lines, which increases near-end crosstalk. At the same time, the terminals only resist each other through their own elasticity. Long-term use can easily cause the connection to be not tight enough, and faults are prone to occur during signal transmission. Summary of the invention

[0004] The technical problem to be solved by the present invention is that there is great interference in the uniform horizontal arrangement of terminals, resulting in low transmission efficiency. In view of the above-mentioned defects of the prior art, an RJ45 connector with stacked terminals is provided.

[0011] Furthermore, the second bending point is in an opposite direction to the first bending point, and the bending height is greater than the height of the first bending point.

[0012] Furthermore, the upper terminal at the second bend is arranged close to the lower terminal.

[0013] Furthermore, the lengths of the upper terminal and the lower terminal on the bending surface and the widths of the upper terminal and the lower terminal on the bending surface are the same.

[0014] Furthermore, the second bending part of the upper terminal and the second bending part of the lower terminal are respectively located in the bending surface.

[0015] Furthermore, the upper terminal and the lower terminal are also provided with a third bending portion, and the third bending portion is convexly arranged relative to the plane of the second bending portion.

[0016] Furthermore, the upper terminal and the lower terminal are respectively provided with a plurality of fourth bends bent to the left and a fifth bends bent to the right, and the fourth bends and the fifth bends are arranged in a cross-layered manner.
