The two adjacent first gold fingers 111 that slide through the gap 113 avoid that the first gold finger 111 is connected to the first gold finger and powered on at the same time when the first gold finger 111 is connected to the shrapnel when it is inserted and powered on at the same time, or when it is pulled out. To avoid problems such as current surge overshoot and current inversion during the insertion process, and at the same time, the contact shrapnel only needs to be powered on and off with the second and first gold fingers 151, and there is no need to repeatedly power on and off.

The substantial coincidence means that the centerline A and the centerline B are completely coincident on a straight line, or may not be completely coincident, that is, the centerline B is located on both sides of the centerline A and the distance from the centerline A belongs to the gold finger connector. 10 The specific amount within the manufacturing tolerance range should be subject to the understanding of those skilled in the art. The centerline B of each of the second-first gold fingers 151 and the centerline A of the gap 113 are substantially coincident to ensure that the contact elastic piece corresponding to the second-first gold finger 151 achieves good contact with the second-first gold finger 151 , In order to achieve better signal transmission effect.

Further, the minimum distance between the first row of gold fingers 11 and the second row of gold fingers 15 meets the requirements of electrical short circuit, and the maximum distance is less than the length of the shortest gold finger in the gold finger connector 10 . Electrical short-circuit means to avoid short-circuiting between the first row of gold fingers 11 and the second row of gold fingers 15 through wires or direct contact, and the maximum distance satisfies that when the gold finger connector 10 is plugged with the female connector, it is the same as the first row. The contact elastic pieces connected with the second row of gold fingers 15 have sufficient travel and ensure that they can normally contact with the second and first gold fingers 151 .

The female connector is electrically connected normally. The reference line in this embodiment is the center line of the first gold finger connected to the communication signal.

As another specific implementation manner of the embodiment of the present invention, the plurality of first gold fingers 111 at least include a grounded first gold finger, a first gold finger for transmitting power signals, and a first gold finger for receiving communication signals. In this case, the parts of the plurality of first gold fingers distributed on each side of the reference line satisfy: the length of the grounded first gold finger is greater than the length of the first gold finger for transmitting power signals, so The length of the first gold finger for transmitting the power signal is greater than the length of the first gold finger for receiving the communication signal. At least including means that the plurality of first gold fingers 111 may also include gold fingers that transmit power signals or other non-connecting signals.
