[embodiment]

As shown in Figure 1 to Figure 3, the utility model electric connector 100 comprises insulating body 1, is contained in the plurality of terminals 2 of insulating body 1 and is covered in the shielding casing 3 in the insulating body outside.

As Fig. 4 and shown in Figure 5, it is rectangular-shaped that insulating body 1 roughly becomes, and it is provided with base portion 11 that extends along fore-and-aft direction and the receiving space 14 that is positioned at the hollow of base portion 11.Wherein, fore-and-aft direction also is defined as docking direction or first direction.Base portion 11 is provided with rear wall 15 in rear side, and rear wall 15 projection in receiving space 14 forms a hyoplastron portion 13, hyoplastron portion 13 upsides be provided with run through rear wall 15 terminal conduit 131 to accommodate terminal 2.The outstanding enhancing portion 12 that surrounds base portion 11 that forms outside the front end lateral of base portion 11, enhancing portion 12 is close to the front end of receiving spaces 14 and can strengthens the intensity of base portion 11.Stepped between this enhancing portion 12 and the base portion 11, wherein be formed with connecting wall 122 between the upper wall 110 of enhancing portion 12 and base portion 11 perpendicular to upper wall 110, upper wall 110 places that connecting wall 122 is close to base portion 11 are recessed to form some trapezoidal resettlement sections 121 forward, enhancing portion 12 is run through on butt joint direction top in resettlement section 121, with dock direction on the vertical vertical direction (this direction also claims second direction) resettlement section 121 be and be open upwards shape, promptly run through the upper surface 120 of enhancing portion 12 and form an opening 1214.Described resettlement section 121 comprises the first side wall 1211, second sidewall 1212 that is positioned at butt joint direction both sides and is positioned at resettlement section 121 terminal the 3rd sidewalls 1213 that connect the first side wall 1211 and second sidewall 1212.Distance between the first side wall 1211 and second sidewall 1212 is increase tendency gradually from opening 1214, and the bottom of resettlement section 121 also is formed with the bottom surface 1215 of extending forward from upper wall 110 levels of base portion 11.See this resettlement section 121 from base portion 11 rear wall sides, it roughly is the dovetail groove shape.

As Fig. 1, Fig. 2 and shown in Figure 4, terminal 2 is provided with holding parts 22, the contact site 21 of horizontally extending lengthwise reaches the connecting pin 23 that is bent extension by holding parts 22 opposite sides downwards before holding parts 22 1 side direction.Described terminal 2 is contained in the terminal conduit 131 of insulating body, and contact site 21 is exposed in the described receiving space 14, and connecting pin 23 then extends the rear wall 15 of insulating body.

As Fig. 4 and shown in Figure 6, described shielding casing 3 is bent to form and is covered in the outside of insulating body 1 by a sheet metal punching press, and the upper surface 30 of shielding casing 3 extends to form some trapezoidal holding sections 31 forward along butt joint direction levels.This holding section 31 comprises upper side 311, the downside 312 that is parallel to each other, first side 313 and second side 314 and the front surface 315 that connects upper side 311, downside 312.Wherein the distance between first side 313 and second side 314 is increase tendency gradually from upper side 311 to downside 312.

In assembling process, shielding casing 3 will move forward along the butt joint direction, in the resettlement section 121 of its holding section 31 corresponding insertion insulating bodies 1, first side 313, second side 314, downside 312 and the front surface 315 of holding section 31 respectively with the subsides that offset of the first side wall 1211, second sidewall 1212, bottom surface 1215 and the 3rd sidewall 1213 of the resettlement section 121 of insulating body 1, and the upper side 311 of holding section 31 just and the opening 1214 of the resettlement section 121 of insulating body 1 match.At this moment, the upper side 311 of the upper surface 30 of shielding casing 3 and holding section 31 is equal with the upper surface 120 of enhancing portion 12.In brief, the size of holding section 31 in the vertical directions can not exceed the upper surface 120 of enhancing portion 12, thereby can additionally not increase the size of electric connector yet.In addition, electric connector in welding process, the holding section of shielding casing 3 31 since with resettlement section 121 interference engagement, can effectively be supported in the enhancing portion 12 of insulating body 1, thereby prevent the buckling deformation of insulating body front end.
