When the plurality of cables 200 are connected to the electrical connector 100, the inner conductor 204 of the cable 200 is connected to the corresponding first tail portion 422 of the first conductive terminal 42 and the corresponding second tail portion of the second conductive terminal 52. 522 fixed connection (such as welding) to achieve electrical conduction. The shielding layer 206 is connected to the ground plate 6 (for example, welded), so that The shielding area is increased and the shielding effect is improved. When the cable 200 adopts the coaxial line of the present invention, the cable 200 can be directly welded to the electrical connector 100, which simplifies the process and reduces the cost.

The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. The understanding of the present invention should be based on those skilled in the technical field. Although the present invention has been described in detail with reference to the foregoing embodiments in this specification.
