In some embodiments, again with reference to fig. 6 and 7, the first surface 122 and the second surface 123 of one end of the tongue 12 are each provided with a third pin.
When the male plug 1 is in the first flat state, the first board surface of the PCB adapter board 11 is above the second board surface, and in this case, the third pin provided on the first surface 122 abuts against the convex contact 141 of the elastic sheet 14 located on the first board surface, and the tongue piece 12 is electrically connected with the elastic sheet 14.
When the male plug 1 is turned 180 ° relative to the first flat state and then is in the second flat state, the second board of the PCB adapter 11 is above the first board, and in this case, the third pin disposed on the second surface 123 abuts against the male contact 141 of the elastic sheet 14 located on the second board, and the tongue 12 is electrically connected with the elastic sheet 14.
I.e. the two spring plates 14 are not simultaneously electrically connected to the tongue 12, but one of the two spring plates 14 can be electrically connected to a third pin on the tongue 12 via the male contact 141. When the first board surface of the PCB adapter 11 faces upwards, the elastic sheet 14 is an elastic sheet 14 mounted on the first board surface; when the second board surface of the PCB adapter 11 faces upwards, the elastic piece 14 is an elastic piece 14 mounted on the second board surface; so that the end of the tongue 12 where the third pin is located can be electrically connected to the spring 14.
In some embodiments, the tongue 12 and the tongue housing 13 are hinged by a hinge shaft 15.
Specifically, the hinge shaft 15 is fixedly connected with the middle part of the tongue piece 12, two ends of the hinge shaft 15 are respectively hinged with the tongue piece housing 13, so that two ends of the tongue piece 12 can be turned around the hinge shaft 15 by a certain angle, and further, two ends of the tongue piece 12 can adjust the position of the tongue piece 12 according to the flat state of the male plug 1, a third pin at one end of the tongue piece 12 can be electrically connected with the elastic piece 14, and the other end (one end provided with the second pin 121) of the tongue piece 12 and the upper inner wall surface of the tongue piece housing 13 form a slot space 16 for inserting the insert 21 in the female plug 2.
The hinge shaft 15 may be a long shaft penetrating the tongue 12 and having both ends exposed to the tongue 12, or two short shafts, one end of each of which is inserted into the tongue 12 and fixed, and the other end of each of which is exposed to the tongue 12 and hinged to the tongue housing 13.
In some embodiments, referring again to fig. 4 and 5, the end of the tongue 12 where the second pin 121 is disposed is further provided with a counterweight 17, where the counterweight 17 may enable the end of the tongue 12 where the second pin 121 is disposed to be located in a lower position when the male plug 1 is in a different flat state, so that the end of the tongue 12 and the upper inner wall surface of the tongue housing 13 form a slot space 16 into which the ferrule 21 in the female plug 2 is inserted.
The weight 17 may be in the form of a weight 17 block or a weight 17 shaft, and the weight 17 may be embedded in the tongue 12, or may be provided on one or both surfaces of the tongue 12 (in order not to affect the insertion of the ferrule 21).
In some embodiments, a plurality of first pins 111 are disposed on the first board surface and the second board surface. The number of the first pins 111 may be set according to the functional requirement of the USB.
The symmetrical arrangement means that the plurality of first pins 111 on the first board and the plurality of first pins 111 on the second board are symmetrically arranged. The first pins 111 may be electrically connected by a connection line, and the elastic pieces 14 electrically connected to the first pins 111 may be provided corresponding to the first pins 111. For example, the first board has four first pins 111, the second board has four first pins 111, and the male plug 1 of the USB includes eight elastic pieces 14, and the tongue piece 12 has third pins adapted to the number and arrangement of the first pins 111.
