[embodiment]

See also shown in Figure 1ly, the utility model electric connector 100 can be respectively pegged graft for USB 2.0 pin connectors (not icon) or ESATA pin connector (not icon).Electric connector 100 comprises the metal shell 2 and the plurality of conductive terminals of an insulating body 1, coated insulation body.

See also Fig. 2 and shown in Figure 3, insulating body 1 comprises that a upright rear wall 12 reaches from the rear wall two ends the extended two side 13 of one forward, one hyoplastron 11 roughly from the front of rear wall one forward (being first direction) extend, the internal face of two side is provided with the groove of some opening surfaces to hyoplastron 11, form first, second and third step-like wall 131,132,133, first wall, 131 the most close diapires wherein, second wall 132 is between the first, the 3rd wall.Top, the diapire of insulating body then connect.

First conducting terminal 3 is the ESATA conducting terminal, totally 7 and structure are identical, every first conducting terminal 3 comprises a fixed part 31, is positioned at the flat contact site 32 of fixed part front end and the pin 33 that bends downward vertically from the fixed part rear end, and the pin afterbody is provided with the weld part 331 of level.The fixed part 31 and first contact site 32 are embedded in the terminal groove of first surface 110 of hyoplastron 11, first surface 110 almost parallels of first contact site 32 and hyoplastron.Second conducting terminal 4 is the USB conducting terminal, and totally 4 and structure are identical, the elastic contact part 42 of the arc bending that every second conducting terminal 4 comprises fixed part 41, extend forward from the fixed part front end and the pin 43 that bends downward vertically from the fixed part rear end.Second conducting terminal 4 is from the rear wall insertion end pilot trench of the body that insulate, and elastic contact part 42 is positioned at the second surface 111 and the protruding second surface 111 (joining shown in Figure 4) that exposes of part of hyoplastron.Terminal position assurance member 6 is pegged graft for the terminal pin, helps the welding of terminal.

One internal face of the sidewall of insulating body is being provided with accepting groove 134 on first wall 131 near diapire.A pair of detecting terminal 5 is contained in this accepting groove.The detecting terminal comprises fixed terminal 51 and movable terminal 52, and the elastic protrusion part of movable terminal is given prominence to first wall 131, and clinch 522 from the actuating of butt connector to inner the moving of accepting groove that can finish its front end under contacts with the front end 512 of fixed terminal 52.

Shielding casing 2 is formed by a sheet metal, the sidewall of encirclement insulating body 1 and top, diapire, and the roof of shielding casing forms one with the sidewall of insulating body and rear wall and docks chamber 16, and hyoplastron 11 extends into this butt joint chamber from first direction.The top of shielding casing, diapire are respectively equipped with the elastic arm 22 that extends to the butt joint chamber, to reach fixing and ground connection effect to pin connector, the front-end edge of top, diapire bends laterally, and punching press has butt sheet 23, and this butt sheet 23 can contact with casing such as computer.The both sides of shielding casing are extended with pin 24 downwards.

Hyoplastron 11 also comprises two sides 112 and the front end face 113 that is positioned at first, second surperficial both sides, these two sides 112 are towards the internal face of sidewall, describe for convenient, the direction that defines sensing another side, a side is a second direction, first and second conducting terminal all is arranged in parallel along second direction, and each terminal then extends along first direction.Hyoplastron 11 is provided with a more shallow slit 14, and this slit 14 runs through the front end face 113 of hyoplastron forward, runs through the two sides 112 of hyoplastron along second direction, then runs through the rear end face of rear wall backward.One ground strip 7 is contained in this slit 14, and the two sides of this ground strip 7 are roughly concordant with the two sides of hyoplastron 112, not outstanding two sides; Front end then slightly inwardly contracts than the front end face 113 of hyoplastron.The rear end of ground strip 7 is integrally formed with a pin 71, and this pin then is connected in the ground path of circuit board.Certainly, this ground strip 7 also can extend the pin that contacts with shielding casing, and perhaps pin separates moulding with ground strip, and both are overlapped in together.Hyoplastron is divided into hyoplastron by slit 14 and reaches hyoplastron down, and this upper and lower hyoplastron and rear wall are connected in one.First, second surface of hyoplastron helps to strengthen the intensity of hyoplastron being provided with ribs 15 with the rear wall junction.
