The fourth terminal group 44 is disposed on the first surface of the third tongue 42. The second terminal group 43 is a terminal group of a non-micro universal serial bus bar specification, and the fourth terminal group 44 is a terminal group of a miniature universal serial bus bar specification. In this embodiment, the second terminal group 43 is matched with the foregoing. The specification of the second terminal set 15 of the receptacle electrical connector 1. The transverse section of the third tab 42 is generally schematic. The first surface 422 is a portion where the top surface of the third tongue 42 is partially recessed, and the second portion 421 is the bottom surface of the third tongue 42.

- The worker can also plug the connector electrical connector 4 in addition to the plug electrical connectors 2, 3 of the aforementioned A-type micro universal serial bus. Connection Γ plug electrical connection 11 4 plug the socket electrical connection 11 1 Shaw, plug electrical connection Sen 4 third tongue 42 into the socket electrical connector] jk筮-工吉月12 /, a tongue between the ,, And the socket connector is the first - 12 square

11 in the recessed area of the top surface of the third tab 42 of the plug electrical connector 4, whereby the fourth terminal set 44 of the third tab 42 of the plug electrical connector 4 is in contact with the first terminal set 14 of the receptacle electrical connector 1 Forming an electrical connection for transmitting the signal of the universal serial busbar specification, the third terminal set 43 of the third tongue 42 of the plug electrical connector 4 is in contact with the second terminal set 15 of the second tongue 13 to form an electric Sexual connection, which can transmit signals of non-passing dragon flow specifications. In addition, in the present embodiment, as shown in FIG. 2, FIG. 4, and FIG. 6, the socket is electrically connected to the bottom of the second tongue piece 13 and a protrusion 13 is formed at the bottom, so that the second tongue 13 is in the left-right direction. The cross section is substantially shaped, and when the plug electrical connection 4 is inserted into the socket electrical connector j _, the socket electrical connector _ the second tongue υ of the bump 130 corresponds to the notch 41 嵌入 embedded in the plug electrical connector 4, The cooperation between the plug electrical connection state 4 and the socket electrical connector} forms a foolproof effect. As shown in FIG. 7, in the present embodiment, the length of the second tongue 13 of the socket electrical connector 1 extends toward the socket 112 is shorter than that of the first tongue 12, which can reduce the electrical connection between the connector electrical connector 4 and the socket. When the device is inserted, the second tongue is hit by the left and right sway of the socket electrical connection. In addition, in the embodiment, the socket electrical connector further includes a base portion 1 , and the rear end of the first tongue 12 and the rear end of the second tongue 13 are integrally connected through a base portion 10. It is to be noted that, referring to FIG. 4 and FIG. 6, in the embodiment, the plug electrical connector has two sets of terminal sets 43, 44, but in another implementation, the plug may be only the third. The terminal set 43, without the fourth terminal set 44 of the miniature universal rate column busbar specification, for example, may be a plug for the earphone. When the plug electrical connector is inserted into the socket electrical connector, it is 1357694

Only the second terminal set 43 is in contact with the receptacle electrical connector, and the area in which the top surface of the first tab 12 of the receptacle electrical connector 1 is recessed is merely the same as the first terminal. The second terminal set 15 of 1 is still extended into the third tab 42. The terminal set 14 corresponds to the contact heddle. The present invention improves the receptacle electrical connector 1 to a set of terminals other than the miniature universal serial busbar specification. In addition to 14th, it is also used to transmit other specifications (such as audio and other shouts) - (four) sub 15

In order to increase the versatility of the electrical connector of the socket, the device can also reduce the space of the electronic device due to the single socket electrical connector J, and can have two transmission rules when it is disposed in an electronic device. . The corresponding plug electrical connector 4 can have a micro universal universal bus bar and a non-micro universal string in addition to the transmission specifications corresponding to another set of terminal sets that are electrically connected to the socket. Columns are two types of transmission specifications.
