Abstract

The utility model relates to an electric connector structure, which mainly comprises a body, wherein the back side of the body is provided with a plurality of corresponding upper jacks and lower jacks. Holding pins are inserted and positioned in the upper jacks, and signal pins are inserted and positioned in the lower jacks. The tail ends of the signal pins emerge out of the body, so that the tail ends can be soldered on a circuit board. The front of the body is provided with a slot connected to the upper jacks and the lower jacks, and a metallic shell is sheathed outside the body. The metallic shell extends out a ground pin which is connected with the ground terminal of the circuit board, and an electrode pin which is pressed downwards is arranged on the metallic shell. When a butted electric connector plug is inserted into the body through the slot of the front end of the body, the electric connector plug can be tightly held and positioned by the signal pins and the holding pins, and the electrode pin on the metallic shell can contact the metallic surface on the electric connector plug. Thus, the electromagnetic wave on the electric connector plug is exported to prevent the signal pins from being disturbed by the electromagnetic wave.

The utlity model has following advantage:

1. be provided with upper and lower corresponding clamping pin and signal pin in the utility model body, walk back and forth as the holder to form one, the tight clamping of the electrical connector plug location with inserting in the body makes this electrical connector plug be difficult for being separated with body.

2. an electrode pin that presses down is set on the metal shell of the utility model body, and this electrode pin contacts with the metal shell of electrical connector plug in inserting body, and the electromagnetic wave on this electrical connector plug is derived, and avoids Electromagnetic Interference signal pin.
