The sheet 41, and the other structures of the metal casing 6 are substantially the same as the above-mentioned metal casing, and will not be described again. /, 10/14 M4285 67 The present invention is provided with a grounding device 4 on the cable connector. One end of the grounding strip 41 of the grounding device 4 is in contact with the second contact portion 33 of the second terminal 3, and the grounding wire 53 is electrically connected to the grounding strip 41. The grounding of the cable connector and the cable 5 can be achieved to avoid electromagnetic waves (EMI) affecting the transmission signal of the cable connector. The grounding structure of the creation is greatly simplified, which not only saves labor and time, but also increases the production capacity, so as to facilitate a large number of In production, it is not easy to cause welding errors, and the reliability is good, which can improve the yield. However, the above description is only the preferred embodiment of the creation, and it is not intended to limit the scope of patent protection of this creation. The equivalent changes of the content are all included in the scope of protection of this creation, and are combined with Chen Ming.
