Description of the Invention: [Technical Field] The present invention provides an electrical connection as a combination, and more particularly to an improved electrical connector assembly having a shielding housing contact mode and a ground terminal contact mode. [Prior Art] With the development of signal south-speed transmission, for the connector combination of the electrical connector combination, especially the contact terminal, the contact between the metal terminals is likely to cause static electricity during the plugging and unplugging process of the connector. Generated, thereby affecting the reliability of the terminal transmission signal. On the other hand, the degree of integration of modern circuit boards is becoming more and more ambiguous. When adjacent electrical connectors on the circuit board transmit signals, they are likely to generate electromagnetic interference with each other, and external electromagnetic radiation is installed on the circuit board. The electrical connectors are also susceptible to electromagnetic interference, causing mutual interference during signal transmission. In order to solve the above problems, the industry usually adopts a structure that is grounded first to avoid the generation of static electricity between the terminals, and a mask that shields the housing with metal to prevent electromagnetic interference. In U.S. Patent No. 5,356,300, a prior grounding structure is disclosed. The embodiment of the present invention is: a guiding post is disposed on a side of the butting portion of the male connector; a guiding slot is disposed in the guiding post, and an elastic grounding terminal is received in the receiving slot, and the contact portion of the elastic grounding terminal is higher than The pair of insulative housing abutting portions are exposed to the outer surface of the receiving groove. Therefore, when the male and female couples are docked, the contact of the two n妾 grounds precedes the contact of the conductive terminals, thereby effectively preventing the occurrence of the conductive terminal connection. However, the electrical connector assembly does not have a shielded housing structure, and it is difficult to avoid external electromagnetic interference, resulting in a decrease in reliability of terminal signal transmission. « In the second application of the patent application No. 63389, a first grounding junction f is also disclosed. The specific implementation manner is as follows: the two ends of the insulating body of the female connector are ΓρΓ, the abutting surface of the guiding column is slightly higher than the abutting surface of the abutting portion of the insulating body, and one grounding is connected to the receiving groove of the butting surface of the guiding column. Therefore, when the male and female connectors are docked, the contact of the contact with the Japanese terminal is prior to the contact of the conductive terminal, thereby effectively avoiding the conductive end = the insulation of the male connector is covered with a metal shielding shell, the piece , 2, 2: The contact extends to the inner cavity of the body, the male connector further includes a grounded metal contact 2, and the (4) connection, the grounded metal piece of the two connectors passes through the rigid interference friction photo system through the dry axe The elastic contact achieves the effect of electrical conduction. However, due to the grounding metal ', y °, the dimensional accuracy of the metal piece is required to be high, and the metal piece is prone to wear during the process of repeatedly using the connector 1 1264857, resulting in low reliability of electrical contact between the two metal sheets. Therefore, it is necessary to improve the contact mode of the metal shielding case and the grounding terminal of the above electrical connector to overcome the drawbacks of the prior art.
