[embodiment]

See also Fig. 1 to Fig. 2, electric connector 100 comprises shielding casing 1, insulating body 2, is assembled in the complex conduction terminal 3 and the dust cap 4 of insulating body 2.

Shielding casing 1 comprises roof 11, diapire 12 and the pair of sidewalls 13 relative with roof 11, and each wall encloses and forms host cavity 14 and docking port 17, and the first half 111 of roof 11 is than latter half of 112 height.Insulating body 2 comprises base portion 21 and from the docking section 22 that base portion 21 extends forward, these docking section 22 upper and lower surfaces are equipped with terminal groove 221, and this docking section 22 is contained in the aforementioned host cavity 14.The afterbody 33 that contact site 32 that conducting terminal 3 comprises holding parts 31, extend forward from holding parts 31 and holding parts 31 thereof extend back, holding parts 31 is immobilizated in the base portion 21 of insulating body 2, contact site 32 is arranged in each terminal groove 221, and this contact site 32 is exposed to lower surface on the docking section 22, afterbody 33 extends outside the base portion 21, in order to be soldered to circuit board (figure does not show).

See also Fig. 2 to Fig. 5, dust cap 4 is made by metal material, and it rotatably is arranged at docking port 17 places of shielding casing 1, and is articulated with the two side 13 of shielding casing 1.The corresponding position, 13 upper end, two side of shielding casing 1 is provided with a pair of location hole 131, dust cap 4 comprises lid 42 that is covered in docking port 17 places and the rotating shaft 41 that stretches out and form from two ends, lid 42 top, the rotating shaft 41 of lid 42 1 ends is provided with elastic component, this elastic component is positioned at host cavity 14, in the present embodiment, elastic component is a torsion spring 5.The rotating shaft 41 of lid 42 1 ends is longer than the rotating shaft 41 of the other end, should long rotating shaft 41 be provided with compressible torsion spring 5.When dust cap 4 is installed, the rotating shaft 41 that will be arranged with torsion spring 5 earlier is inserted in the positioning hole corresponding 131, compress this torsion spring 5 then, thereby the rotating shaft 41 of the other end is inserted in the location hole 131 of aforementioned another sidewall 13, this torsion spring 5 links to each other with lid 42 1 sides and corresponding sidewall 13, and lid 42 is vertically sagging.Because this dust cap 4 is made by metal material, when preventing that dust from entering this electric connector 100, can eliminate the static that produces in the docking operation preferably, and this dust cap 4 is simple in structure, makes easily.Lid 42 lower ends of dust cap 4 are provided with and docking section 22 corresponding recesses 43, and these recess 43 width are greater than the width of docking section 22.

In addition, roof 11 front ends of shielding casing 1 are provided with the guide part 15 to host cavity 14 inner bendings, and not only the insertion to butt connector play the guiding role, and this guide part 15 is connected to lid 42, can avoid lid 42 to turn up.Guide part 15 and rotating shaft 41 are positioned at the same side of docking port, and guide part 15 is terminal to be positioned at same plane with roof 11 is latter half of.
