Embodiment

About the aforementioned of the utility model and other technology contents, characteristics and effect, in the detailed description of following cooperation, can clearly appear with reference to a preferred embodiment of accompanying drawing.

Consult the preferred embodiment of Fig. 1 for the utility model electric connector 1.Electric connector 1 is used to electrically connect a chip module (not shown) and a circuit board (not shown).Electric connector 1 comprises a plurality of terminals 2 and an insulating body 3, and Fig. 1 only illustrates a plurality of terminals 2 as representative, and present technique field personage is when the zone that can understand terminal 2 actual distribution.

Fig. 2, Fig. 3 and Fig. 4 are the forms that terminal 2 appears respectively at different angles, and terminal 2 is processed by the metallic conduction material and comprised a flat main body 21, an elastic arm 22, one first contact site 221, one second contact site 23, a lug 212 and a strip connecting portion 213.

Main body 21 centre form a perforate 211, and respectively form one first location division 214 and one second location division 215 in the relative both sides of perforate 211.Lug 212 is general curved and extended outside the perforate 211 by a upright inboard of the perforate 211 of main body 21.Wherein, lug 212 extends toward the direction away from main body 21 from one of perforate 211 upright inboard, and counter-rotating is extended toward the direction near main body 21 again.Elastic arm 22 is upwards bent by main body 21 end faces and extends, and forms one first contact site 221 in end, electrically connects for chip module.Second contact site 23 bends extension downwards by main body 21 bottom surfaces and electrically connects with power circuit board.Preferably; Main body 21 has one first relative plate face 218 and one second plate face 219; First contact site 221 and second contact site 23 and the first plate face 218 are positioned at the same side, and the lug 212 and the second plate face 219 are positioned at the same side, that is to say; Lug 212 and first contact site 221, second contact site 23 are positioned at the relative both sides of main body 21 so that during mounting terminal 2 to the action of exerting pressure of lug 212 end faces.

At present embodiment, the end face of first location division 214 forms a strip connecting portion 213, but strip connecting portion 213 also can be formed at the end face of second location division 215; Or it is as shown in Figure 5; Each terminal 2 comprises two strip connecting portions 213; These two strip connecting portions 213 are formed at the end face of first location division 214 and second location division 215 respectively, and above-mentioned all is disposable set-up mode, so should not be limited to the content of present embodiment.

Fig. 6, Fig. 7 and Fig. 8 are the partial enlarged drawings of electric connector 1, explain that terminal 2 is installed in the form that is provided with of insulating body 3.Insulating body 3 comprises a relative end face 31 and a bottom surface 32, a plurality of stop section 34 that is installed in terminal groove 33 and a plurality of confession perpendicular positionings of terminal 2.

Terminal groove 33 runs through the end face 31 and bottom surface 32 of insulating body 3 respectively, and respectively has a major trough portion 331, one first location slot part 332 and one second location slot part 333.The first location slot part 332 and the second location slot part 333 are stretched out by the relative both sides of major trough portion 331 respectively, and first location division 214 that first location slot part 332 correspondences are held terminal 2 makes first location division 214 be fastened in the first location slot part 332; Second location division 215 that second location slot part 333 correspondences are held terminal 2 makes second location division 215 be fastened in the second location slot part 333.Stop section 34 is lug 212 positions of each terminal 2 of correspondence respectively, and protrude out from the internal face 35 of corresponding each terminal groove 33.The end face 341 of stop section 34 and is resisted against the bottom surface 216 of corresponding lug 212 between the end face 31 and bottom surface 32 of insulating body 3.

As above-mentioned, each terminal 2 is contained in a terminal groove 33, and the main body of terminal 2 21 is interfered and is fixed in the

terminal groove

33, and 34 end face 341 is abutted against in the stop section in the bottom surface 216 of lug 212.In addition; When lug 212 was placed in terminal groove 33, its vertical walls 217 was not close to the internal face 35 that insulating body 3 defines corresponding terminal groove 33, therefore; When terminal 2 is assembled in insulating body 3; The space that is installed with lug 212 owing to terminal groove 33 correspondences is spacious relatively, need not lug 212 contraposition accurately at assembling process, and lug 212 sizes and the bigger tolerance of curved shape tolerable; And when 34 end face 341 is abutted against in the stop section in the bottom surface 216 of lug 212; Know that promptly terminal 2 has arrived the location; Can produce the positioning action of vertical direction to terminal 2; So can whole terminals 2 be controlled at roughly the same height, second contact site 23 that makes whole terminals 2 is copline roughly, links and can form excellent electrical property with circuit board.

In sum; The terminal 2 of the utility model electric connector 1 is easy to be installed in the insulating body 3, and can locate in vertical direction, and second contact site 23 that makes whole terminals 2 is copline roughly; Link and can form excellent electrical property, so can reach the purpose of the utility model really with circuit board.

Yet the above; Be merely the preferred embodiment of the utility model; When not limiting the scope that the utility model is implemented with this; Be that all simple equivalent of being done according to the utility model claims scope and utility model description change and modification, all still belong in the scope of the utility model protection.
