In the embodiment, the guiding is (4〇): The long fins form a flange on each of the two opposite long sides of the sheet, and the two flanges (41) are respectively engaged in the two recesses (13), and one of the short sides of the sheet extends - signal The pin (42) is opposite to the signal pin (42 = (four) contact piece (43)'. The two contact pieces (43) are inclined obliquely toward the inner side I: 'pre-holding a pitch' under normal state, two contacts The piece (43) is connected to the ground layer (23), and when the conductive outer is pushed, the two contact pieces (43) are brought into a floating state, that is, in contact with the M373593 insulating layer (22). a latch (50) is disposed in parallel with the abutting portion (2) and telescopically inserted into the insulative housing (10), and a ring groove (51) is formed on an outer surface of one end of the telescopic pin (5〇) And extending into the accommodating space (12) in the insulating body (1 ,), the edge of the conductive sheet (40) is tightly coupled in the ring groove (51), and the other end of the telescopic pin (50) is outward Extending out of the insulation The outside of the body (10); as shown in the third figure, when the telescopic pin (5〇) is normally not pushed or pressed by external force, the contact piece (43) and the ground layer of the conductive piece (4〇) are maintained (23> In contrast, when the telescopic pin (5〇) is pressed from the outside to the inside, it moves toward the inside to drive the contact piece (40) to slightly bend to contact the contact piece (43) with the insulating layer (22) to become a floating connection. As shown in the first figure, 'in practical applications, this creation can be combined with an output connector (2) to form a connector for the AC/DC transformer (3) of the notebook computer as an example' The input end of the AC/DC transformer receives AC power via an AC power plug (6), and the output end is connected to a wire consisting of a DC power wire and a signal wire, and an output connector (2) is connected at the end. The output connector (2) is adapted to be coupled to the DC power plug (1) and electrically connected to the two power pins (31) (32) and the conductive sheet (40). The output connector of the embodiment (2) The system is in the shape of a cylinder, which can be inserted in a tight fit. In the opening (11) of the flow power plug (1), a jack corresponding to the power pin (31) (32) and the signal pin (42) is formed on the top surface of the output connector (2), so that the power pin (31) (32) and the signal pin (42) can be connected to the power supply lead and the signal lead. Please refer to the fourth and fifth figures. When the notebook is to be charged, the DC power plug (1) is docked. The part (2〇) is inserted into the charging 6 M373593 hole of the notebook computer. At this time, the telescopic pin (50) is retracted by the casing of the notebook computer, thereby causing the conductive piece (40) to bend. The two contact pieces (43) are brought into contact with the insulating layer (22). Therefore, the conductive sheet (10) is changed from the contact with the ground layer (23) to the floating state. This state change can be transmitted back to the internal control circuit of the AC/DC converter (3) via the wire. The control circuit can determine whether the DC power plug (1) is connected to the notebook computer according to the state change signal, and the state change signal can be used as a trigger signal, for example, as a power saving mechanism trigger signal 'When the DC (10) plug (1) is not with the note When the computer is connected, the 'DC change' can be made, and the device (3) can start the power saving mechanism by itself to save power consumption. According to the monthly description of the month, the DC power plug (1) of the present invention, in addition to the original supply force, integrates the DC power plug (1) to determine whether the DC power plug is connected to the electronic product, thereby outputting a state change signal, which can be changed. The supply + A - two aa forks are supplied to their circuit reference applications to produce more valuable accessory functions.
