[embodiment]
See also Fig. 1 to shown in Figure 5, the utility model electric connector comprises insulating body 1, be immobilizated in elasticity the first terminal 2, elasticity second terminal 3 on the insulating body 1 and be assembled in shielding casing 4 on the insulating body 1.
See also Fig. 3 and shown in Figure 4, described insulating body 1 has the base portion 10 of longitudinal and from docking section that base portion 10 extends forward.Described docking section comprises first wall extension 11 and second wall extension 12 of relative extension, forms a receiving space 13 between described two wall extensions.Described first wall extension 11, second wall extension 12 are respectively the diapire and the roof of insulating body 1.The exterior region of described first wall extension 11 is provided with flank 110, and described flank 110 is roughly the same at width on base portion 10 longitudinallies and the width of first wall extension 11 on base portion 10 longitudinallies.Form a long and narrow recess between described flank 110 and the base portion 10.First wall extension 11 be provided with connect first wall extension 11 be used to accommodate first groove 111 of the first terminal 2 and between per two first grooves 111 and on electric connector butt joint direction, be shorter than second groove 112 of groove 111, described first groove 111 intersects along electric connector butt joint direction extension and with flank 110, so first groove 111 runs through flank 110 on the direction perpendicular to first wall extension 11.As shown in Figure 5, described second wall extension 12 is provided with the terminal containing slot 14 that communicates with receiving space 13.The front end of terminal containing slot 14 is provided with the otch 120 that runs through second wall extension, 12 upper and lower walls and front end face.
See also Fig. 1 to shown in Figure 5, described the first terminal 2 comprises the holding parts 20 that is immobilizated on the base portion 10 and extends elastic arm 21 in first groove 111 from holding parts 20.Described elastic arm 21 have first contact site 211 that protrudes in the receiving space 13 and than first contact site 211 more near holding parts 20 and protrude out direction second contact site 212 opposite with first contact site 211.
Described second terminal 3 comprises that the holding parts 30 that is immobilizated on the base portion 10, the elastic arm 31 that extends in the terminal containing slot 14 from holding parts 30 reach the weld part 32 that extends with elastic arm 31 rightabouts from holding parts 30 edges.Have on the described elastic arm 31 and protrude in the receiving space and the contact site 311 relative with first contact site 211 of elastic arm 21.Can hold the butt joint attachment between described two elastic arms 21,31 and insert, the contact site 311 and first contact site 211 with dock the attachment electric connection.When the butt joint attachment inserted, second contact site 212 contacted with shielding casing on being covered in insulating body 1, thereby sets up grounding path.
Described shielding casing 4 comprises and is covered in first side plate 41 on first wall extension 11 and in the recess between flank 110 and base portion 10 and is covered in second side plate 42 on second wall extension 12.Described first side plate 41 is provided with two holding parts 410 that are immobilizated on the base portion 10, described two holding parts 410 are respectively near the both ends of shielding casing 4, and two holding parts 410 are symmetrical arranged with the unequal middle part that is two holding parts 410 are not relative shielding casings 4 of distance between the close separately end.The edge of described second side plate 42 is extended with the weld part 420 that can be welded on the circuit board and is positioned at second side plate, 42 two ends and can be immobilizated in retaining sheet 42 1 on the circuit board.Described weld part 420 also can be arranged on first side plate 41 or first side plate 41 and second side plate 42 on be equipped with weld part 420.
The head of first contact site 211 of described the first terminal 2 is that the free terminal of the first terminal 2 is relative with the part that first groove 111 connects flank 110, owing to do not cover shielding casing 4 on the flank 110, so the head of first contact site 211 has bigger deformation space.The head of the contact site 311 of described second terminal 3 is relative with otch 120, so it also has bigger deformation space.When the butt joint attachment inserts in the receiving space 13, the signal hop of butt joint attachment electrically contacts with contact site 311, the grounded part of butt joint attachment contacts and compress elastic arm 21 with first contact site 211 makes second contact site 212 contact with first side plate 41 of shielding casing 4, thus, set up grounding path by weld part 420 again.
The intensity that described flank 110 has strengthened first wall extension 11 makes the wall extension 11 of winning be not easy to break, and the existence of flank 110 improved the condition of molding of first wall extension 11, has reduced 11 buckling deformations of first wall extension.
