At the same time, the elastic piece 43" of the metal case 4" and the metal body of the mating connector are also electrically connected. Therefore, the terminal 6" is detected by the metal body of the butt connector. The two metal casings 4" are electrically connected. Since the detecting terminals 6, the fixed feet, and the metal casing 4, the conductive brewing portion 44 are connected to the detecting circuit on the circuit board, When the terminal 6 is detected and electrically connected to the housing 4", the circuit of the debt measuring circuit on the circuit board is turned on, so that the docking connector can be detected to be inserted. This implementation of the terminal is independent of the two-layer structure of the t-connector itself, and it is obvious that this method can also be used in a single-layer electrical connection II. Similarly, the detecting terminals in the first embodiment and the second embodiment are not limited to the single-layer electrical connector, and can be implemented in both the double layer and the second device. In contrast, as can be seen from the description of the above various embodiments, the mating portion of the side terminal may be any one of the non-mating surfaces protruding from the tongue or the (four) outside the tongue, but in general ^ The mouth P is uniformly extended to the metal body receiving area of the docking space, and the matching part of the inner terminal of the area can be connected to the metal body of the docking connector. As in the first embodiment, the yoke 62 of the _ terminal 6 protrudes from the opposite surface 22, and is located between the backside 22 and the top wall* of the adjacent metal casing 4, and is inserted into the metal of the periphery. The top wall of the body can be in contact with the mating portion of the detecting terminal 6. In the case of the method of detecting the terminal 6, the detecting portion 6, the mating portions 62, 24' and the adjacent metal casing 4, and then the 41, when the docking connector is inserted, when the outer connector == The side wall of the metal body of Lai can be connected to the terminal 6" M335068 and emphasizes that the side terminal is reddish and does not cooperate with other terminals. The electrical connector of this age realizes the detection function by docking the metal body of the connector. Only when the docking connector is inserted, will the detection ride be concurrently smashed, and the secret gamma will occur; ^, the side terminal of the electrical connection of the creation and the conductive terminal of the t connector itself There is no fit between the two, so the mutual influence between the conductive terminals is small: in addition, the deformation of the price measurement terminal is small during use, so the influence of permanent deformation caused by elastic failure is also small. This creation is in line with the new patent requirements, and the patent application is filed according to law. However, the above is only a better example of this creation. The scope of the mine is not limited to the above examples. Equivalent modification or change in accordance with the spirit of this creation · All should be covered by the following patent application.
