In the HDMI connector 100 according to the present embodiment, the plurality of contact members 120 are formed of a metal material and are insulated from each other by the insulator 160. Although the HDMI connector 100 according to the present exemplary embodiment has 19 contact members 120, the number of the contact members 120 may be increased or decreased according to the characteristics of the connector.

In the HDMI connector 100 according to the present embodiment, the contact member 120 is connected to a contact portion 122 connected to a corresponding contact portion (not shown) of a corresponding connector (not shown) and a substrate (not shown). And a bent portion 128 that connects the contact portion 122 and the terminal portion 124 to different horizontal positions thereof.

The contact portion 122 is positioned on the protrusion 162 of the insulator 160 and is surrounded by the shell cover 140. The contact portions 122 are arranged in zigzag on two parallel contact planes, namely, the first contact plane 222 (see FIG. 8) and the second contact plane 224 (see FIG. 8). The contact portions 122 of the ten contact members 120 illustrated in FIG. 4 are arranged at regular intervals on the first contact plane 222, and the nine contact members 120 illustrated in FIG. The contact portions 122 are arranged on the second contact plane 224 at regular intervals.

The first contact plane 222 corresponds to one surface of the protrusion 162 formed on the insulator 160, and the second contact plane 224 corresponds to the other surface of the protrusion 162.

The terminal part 124 is bent at a predetermined angle in the contact part 122 to be formed on a plane different from the contact part 122. The terminal portion 124 protrudes out of the shell cover 140 in a direction opposite to the contact portion 122 with respect to the insulator 160. The terminal unit 124 is arranged in four parallel terminal planes, that is, the first terminal plane 242, the second terminal plane 244, the third terminal plane 246, and the fourth terminal plane 248, respectively. For reference, referring to FIG. 9, five terminal units 124 are arranged in the first terminal plane 242, the second terminal plane 244, and the fourth terminal plane 248, respectively, and the third terminal plane 246. Four are arranged.
