The fourth docking portion 10 includes a fourth body 101, a cylindrical ground terminal 33 received in the fourth body 101, and a fourth terminal received in the cylindrical ground terminal 33 and interfacing with the needle-shaped second terminal 523. 32. After the cable connector 200 is docked with the docking electrical connector 100, two different signals can be simultaneously transmitted. After the docking, the second docking portion 52 and the fourth docking portion 10 are located in the third shielding shell 201 and shielded. The outside of the housings 511, 513, in this way, can well reduce the mutual interference generated by the two signals during transmission. In addition, the size of the shielding shells 511, 513 will only be limited by the size of the first body 510 without being limited by the size of the second body 522, that is, when the size of the second body 522 becomes larger, as long as the first body 510 The size of the shielding shells 511, 513 can still maintain the original size. In comparison, the first and second butting portions of the prior art are simultaneously accommodated in the shielding housing, so that the shielding shell The size of the body will be limited by the size of the first and second docking portions.

Of course, the cable connector 200 is not limited to docking with the above-mentioned docking electrical connector 100, as the application requirements change, such as when only one of the first docking portions 51 needs to be transmitted to transmit one of the signals without transmitting two signals. The cable connector 200 can also be used for docking with another docking electrical connector 100' for the purpose. Referring to FIG. 5, the docking electrical connector 100' is removed from the docking electrical connector 100. The fourth docking portion 10 is not connected to the docking electrical connector 100', and only one signal is transmitted after the two connectors are docked. In this way, the cable connector 200 can be respectively docked with two different docking electrical connectors 100, 100', and the same structure can flexibly meet different application requirements. In addition, in order to meet the manufacturing requirements, the second body and the first body in this embodiment may also be integrally formed without separate and independent arrangement.

In summary, the creation meets the requirements of the invention patent, and the patent application is filed according to law.
