Patent ID: 7128591

Claim:
An electrical connection socket structure, into which a plug of a signal wire is inserted for electrical connection, the structure comprising: a plastic base having a hole; a plurality of terminals disposed in the plastic base, wherein each of the plurality of terminals has a pin and an elastic arm, the pin is located below the plastic base, the elastic arm is formed with a contact, and the plurality of terminals comprises a first terminal and a second terminal both having the contacts that may contact each other or be separated from each other; and an insulation block, which is disposed in the plastic base, has a contact slant, and can move the elastic arm of the first terminal, wherein when the plug is inserted into the hole of the plastic base, the plug pushes the contact slant of the insulation block and thus moves the insulation block to press the elastic arm of the first terminal such that the contact of the first terminal is electrically connected to or disconnected from the contact of the second terminal after the contact of the first terminal rubs against the contact of the second terminal by a distance; the contacts of the first terminal and the second terminal are spaced apart by a vertical gap, and the contact of the first terminal is wider than the contact of the second terminal; at least one of the contacts of the first and second terminals has a longitudinal plate face; and at least one of the contacts of the first and second terminal is formed with a guide-in surface to guide the contact of the first terminal to slide in for contact with the contact of the second terminal.
