Reference picture 11, is the second embodiment of the plug connector 100 of the utility model, and Figure 11 is enlarged diagram. Second embodiment is with first embodiment maximum differential：The elastic arm 75 of the present embodiment is different from the elastic arm 75 of first embodiment, The shield shell contact-segment 77 ' ' of the present embodiment from the rear end of elastic arm 75 towards shrinkage pool 25 above extend, ground terminal contact section 76 ' ' from The reflexed of shield shell contact-segment 77 ' ' extends towards the lower section of shrinkage pool 25, ground terminal contact section 76 ' ' and shield shell contact-segment 77 ' ' Section see it, it is in inverted V-shape outward appearance that ground terminal contact section 76 ' ' and shield shell contact-segment 77 ' ' are general.

When shield shell 1 is outer installed in insulating body 2, the medial surface of shield shell 1 touches each shield shell contact-segment 77 ' ', it is in generally inverted V-shape outward appearance with ground terminal contact section 76 ' ' and shield shell contact-segment 77 ' ', shield shell 1 is with forward Shield shell contact-segment 77 ' ' is pushed against, and shield shell contact-segment 77 ' ' is moved towards shrinkage pool 25, facilitates shield shell 1 to install absolutely Simplification outside edge main body 2, avoiding shield shell contact-segment 77 ' ' from producing excessive resistance influences the installation action of shield shell 1.

In addition, arrangement mode of the arrangement mode by plural first contact-segment or so in contrast to plural second contact-segment, There is provided plug connector forward direction be plugged in electric connector for socket it is internal when, the contact-segment of plural number first of plug connector can Connection corresponding with arranging terminal on the plural number of electric connector for socket, and plug connector is reversely plugged within electric connector for socket During portion, the contact-segment of plural number second of plug connector corresponding with arranging terminal on the plural number of electric connector for socket can also connect, and insert Electric connector has the function that not limit and electric connector for socket grafting forward or backwards.

Although the utility model is disclosed above with embodiment, so it is not limited to the utility model, any affiliated Have usually intellectual in technical field, do not departing from spirit and scope of the present utility model, when can make a little change with Retouching, therefore the scope of protection of the utility model ought be defined depending on appended claims institute defender.
