Five terminals 131 to 135 are formed at positions according to the USB 3.0 standard, and correspond to the Rx terminals 131 and 132, the GND terminal 133, and the Tx terminals 134 and 135, respectively.
According to the USB 3.0 standard, the second terminal 130 is defined to protrude from the substrate 110. However, according to the present invention, the second terminal 130 may be formed by etching one region of the substrate 110, and may be configured to form a plane on the substrate 110 like the first terminal 120. That is, the first terminal 120 and the second terminal 130 may have the same height.
According to the present invention, the first terminal 120 according to the USB 2.0 standard and the second terminal 130 according to the USB 3.0 standard can be mounted together with the same height on one board 110, so that the USB 3.0 standard The second terminal 130 formed at the position according to the above may be formed in a plane. Therefore, the second terminal 130 according to the USB 3.0 standard can be formed more easily.
FIG. 2 is a diagram illustrating a connection relationship between a USB connector gender, a USB connector gender, and a USB connector according to an embodiment of the present invention, and FIG. 3 is a cross-sectional view taken along line AA ′ of the USB connector gender of FIG. 2. It is sectional drawing.
2 and 3, the gender 200 for a USB connector according to the present invention includes a body 210, an accommodating groove 240 formed in the body, and a connection part 250 protruding in a direction opposite to the accommodating groove 240. The third terminal 220 may be formed on the connection part 250 and the fourth terminal 230 may be formed on the connection part 250 and spaced apart from the third terminal 220.
The body 210 may include an accommodating groove 240 for accommodating the USB connector 100 illustrated in FIG. 1, and may include a connection part 250 protruding in a direction opposite to the accommodating groove 240.
On the other hand, the connection portion 250 is formed on one side of the body 210. The connection unit 250 is connected to a USB socket (not shown) provided with the USB gender 200 according to the present invention to another electronic device (not shown) connected to the USB connector 100. C) and data transmission, and the size of the connection part 250 is determined according to the standard of USB 3.0.
The third terminal 220 may be formed on the connection part 250. The third terminal 220 includes four terminals 221 to 224, which are a V-BUS terminal 221 according to the USB 2.0 standard, a pair of data terminals 222 and 223, and a GND terminal 224. Can be. Accordingly, the position and size of the third terminal 220 are determined according to a standard that can be inserted into a USB socket (not shown) according to the USB 2.0 standard.
The fourth terminal 230 is formed on the connector 250 spaced apart from the third terminal, and the position and shape of the fourth terminal 230 are determined according to a standard standard that can be inserted into a USB socket (not shown) according to the USB 3.0 standard. That is, the fourth terminal 230 includes five terminals of the Rx terminals 231 and 232, the GND terminal 233, and the Tx terminals 234 and 235, and protrude from the exposed surface of the body 210.
The first contact 226 electrically connected to the third terminal 220 and the second contact 236 electrically connected to the fourth terminal 230 protrude inwardly on an inner upper surface of the accommodation groove 240. Can be.
Although not shown in the drawing, the first contact 226 is formed to correspond to the position of the terminal according to the USB 2.0 standard, it can be configured in four, each of the V-BUS terminal 221 of the third terminal 220 ), A pair of data terminals 222 and 223, and a GND terminal 224.
The first contact point 226 and the third terminal 220 may be electrically connected to each other through the first wire 227 embedded in the body 210.
