A support portion 136 may be formed on the upper side of the mounting portion 203c of the plug terminal 203 so as to project from the third wall portion 130 to one side, and the support portion 136 is formed on the upper side of the mounting portion 203c of the third plug terminal 203. It is formed in a form that covers a part and the lower side is formed in an open form so that the plug connector 10 can be supported more firmly when mounted on the substrate.

Further, the fourth plug terminal 204 faces the third plug terminal 203 and has the same shape.

Further, the first contact portion 210 may be formed so that the distance between the overlapping regions 310 overlapping with the second contact portion 220 is the same as the width of the third extension portion 223, and the first contact portion 210 is the third contact portion. The spacing of the overlapping regions 320 overlapping with 230 may be formed to be the same as the width of the fourth extension portion 233, but the spacing is not limited to this, and the spacing of the overlapping regions may be formed wider. It may be formed narrower.

Therefore, the plug connector according to the embodiment of the technical idea of the present invention secures an additional support section by the overlapping region of the plug terminal and an additional support section such as an inclined surface in the mold portion through the above configuration. By doing so, it counteracts the external force applied to the plug connector and reinforces the strength of the plug connector.

In addition, the plug terminal and the molded part of the connector are strongly supported from each other to protect them from multiple sides, prevent the plug connector from being worn or damaged by external force, and the connector can be fitted by sliding contact with the mating connector. It enables time guidance and has the effect of improving wear resistance due to metal-to-metal contact of the connector terminal on the other side.

Although each embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to each of the above embodiments, and can be manufactured in various forms different from each other. Anyone who has ordinary knowledge in the technical field to which the invention belongs can understand that it can be implemented in other concrete forms without changing the technical idea and essential features of the present invention. Therefore, it should be understood that each of the embodiments described above is exemplary in all respects and not limiting.
