[embodiment]

Ginseng Fig. 1, shielding casing 3, the positioning body 4 that is assembled to insulating body 1 and a pair of fixture 5 that electric connector of the present utility model comprises insulating body 1, be contained in plurality of conductive terminals 2 in the insulating body 1, be connected with group with insulating body 1.

Ginseng Fig. 2,3, insulating body 1 comprise the front end face 100 extended hyoplastrons 12 that a rectangular susceptor 11 reaches from this pedestal 11.Described pedestal 11 comprises the upper surface 101 adjacent with its front end face 100, the lower surface 102 relative with this upper surface 101 and relative with front end face 100 and be connected the rear end face of upper and lower end face 101,102.Extend back and run through the clip slot 13 of pedestal 11 being provided with respectively near described upper and lower end face place from front end face 100 levels, the upper and lower end face of pedestal 11 is cut out a rectangular block respectively and is formed the breach 103 that connects with above-mentioned two clip slots 13.Also be provided with the groove 14 that forms to pedestal 11 sunken insides from bottom land in two clip slots 13, this two groove 14 near and run through described rear end face backward.The both sides central authorities of pedestal front end face 100 are provided with first holding hole 15 of arranging about a pair of, and this two holding hole is between hyoplastron 12 and upper surface 101 and close clip slot 13 bases.Pedestal 11 is provided with a pair of jack 16 that runs through the front and rear end at the left and right end positions place near hyoplastron 12.Be respectively equipped with one and first holding hole 15 on the two side walls 104 of pedestal 11 and be positioned at second holding hole 17 of same level height.Described hyoplastron 12 surfaces are provided with conducts electricity the accepting groove 121 of satin some holding, and these accepting grooves 121 run through pedestal 11 backward.

Ginseng Fig. 2, described conducting terminal 2 is contained in the accepting groove 121, the contact arm 22 that each conducting terminal comprises base portion 21, extended forward by base portion 21, the location division 23 that is extended back by base portion 21 and the afterbody 24 that is continued to extend back by location division 23.Described base portion 21 is contained in the pedestal 11, and the both sides of this base portion 21 are provided with some and hangnails 211 accepting groove 121 interferences.Described contact arm 22 is located in the accepting groove 121 in the hyoplastron 12, and the end of this contact arm 22 is provided with the contact site 221 that electrically connects mutually with other electronic components (not shown).

Ginseng Fig. 2,3, described shielding casing 3 are made by metal material, and it has the socket part 31 that surrounds described hyoplastron 12 and is inserted in a pair of holding piece 32 in described two clip slots 13.This socket part 31 comprises a base plate 311, the side plate that upwards is bent to form of these base plate 311 two ends 312 and bend and engage formed top board 313 relatively by this biside plate 312 certainly, and these top board 313 central authorities have the abutment joint 33 that extends horizontally to shielding casing 3 tail ends from its front end backward.Two holding pieces, 32 middle parts are respectively equipped with a through hole 321, and the part holding piece that is positioned at these two through hole 321 rears is through inside punching press and the corresponding breach 103 that is buckled on described clip slot 13 rears.The back edge of top board 313 and base plate 311 makes progress, bends and form the connecting portion 34 that is connected socket part 31 and described two holding pieces 32 respectively downwards along the front end face 100 of pedestal 11, and holding piece 32 is to form from the bending of connecting portion 34 1 ends.In conjunction with shown in Figure 4, wherein with in the connecting portion that top board 313 links to each other be provided with the location notch 35 that the described fixture 5 of a pair of confession interts, this two location notch 35 is horizontally set at described abutment joint 33 both sides and left-right symmetric.Connecting portion 34 has the front surface 341 and rear surface 342 that forms its thickness, and described two location notchs 35 are located at this between forward and backward surperficial 341,342.Each location notch 35 extends horizontally in a side direction of connecting portion 34 and closes on the rear surface 342 of running through connecting portion 34 behind abutment joint 33 positions more backward, so location notch 35 is L-shaped in connecting portion 34.Described biside plate 312 extends back a pin 36 respectively, and these two pins, 36 corresponding inserted are in the jack 16 of pedestal.

Ginseng Fig. 4,5, identical and corresponding being arranged in above-mentioned two location notchs 35 of described two fixtures, 5 structures, this two fixture 5 is slim-lined construction.Each fixture 5 comprises that the insertion section 51 that is inserted in the location notch 35 reaches from second linkage section 52 of this first linkage section 51 away from the end bending 90 degree formation of abutment joint 33, and the free terminal of this first, second linkage section 51,52 is respectively equipped with first, second end 511,521 of weak point of length.Wherein first end 511 is to form and parallel with second linkage section 52 to the bending of the direction of second linkage section 52, and the second end 521 is that the direction bending to first linkage section 51 forms and parallels with first linkage section 51.These first, second end 511,521 correspondences are fixed in described first holding hole, 15 (see figure 2)s and second holding hole, 17 (see figure 2)s.

As shown in Figure 3, the groove 41 that has the afterbody of some location conducting terminal 2 in the positioning body 4.The holding piece 32 of described shielding casing 3 bottoms extends back pressure pin 322, and this pressure pin 322 is positioned at the bottom of positioning body 4 in case positioning body 4 is loosening downwards.

During assembling, at first conducting terminal 2 is assembled in insulating body 1, then positioning body 4 is assembled in the rear end face of insulating body 1, secondly shielding casing 3 is sheathed on insulating body 1 periphery backward in the past, last mounting fixing parts 5.Before fixture 5 inserts location notch 35, the operator needs earlier fixture 5 to be rotated to second linkage section 52 position straight up, this is because the length of first end 511 is wide than the width of location notch 35, for guaranteeing that first linkage section 51 can insert location notch 35 smoothly, must guarantee the length that highly is not less than first end 511 up and down of this location notch 35 simultaneously.Treating that first linkage section 51 is inserted to revolve backward to turn 90 degrees and first end 511 is plugged behind location notch 35 bottom lands is fixed in first holding slot 15.The operator needs simultaneously second linkage section 52 outwards to be broken into two with one's hands certain angle to prevent that the second end 521 from influencing first end 511 with the sidewall interference of pedestal 11 and being positioned smoothly in first holding hole 51 in rotary course.When first end 511 rotated to level, the operator just held the second end 521 buttons in the hole 17 as for second button simultaneously, thereby second linkage section 52 is clamped on the side wall surface.Because fixture 5 is to select all materials preferably of working strength and toughness, when therefore installing second linkage section 52 is outwards broken into two with one's hands and can't make it produce plastic deformation and lost efficacy.

The part-structure of the holding piece 32 of the utility model electric connector is arranged in the breach 103 of pedestal 11, when docking with butt connector, electric connector prevents that so shielding casing 3 from deviating from insulating body 1, the setting of described fixture 5 has then further strengthened the retain strength between shielding casing and the insulating body, guarantees that electric connector still can make shielding casing firmly link to each other with insulating body under big contact engaging and separating force effect.In addition because the toughness of fixture is better, electric connector in the plug process, can offset a part of external force effect and make can not produce between shielding casing and the insulating body loosening, thereby possess more performance to satisfy client's demand.
