Signal terminal 3 is by being bent to form after the metal lamellar body blanking punching press, it is contained in the conduit 113,117 of above-mentioned matrix 11, please be simultaneously with reference to Fig. 5, signal terminal 3 comprises first signal terminal set 30, secondary signal terminal group 40, the 3rd signal terminal set 50 and the 4th signal terminal set 60.Signal terminal set 30,40,50,60 comprises the

last signal terminal

31,41,51,61 of a structural similarity and the following

signal terminal

32,42,52,62 of a structural similarity respectively, and the arrangement mode of each signal terminal set 30,40,50,60 is similar.Below be that example is introduced with first signal terminal set 30.

The last signal terminal 31 of first signal terminal set 30 reaches down, and signal terminal 32 has included contact site 311,321, holding parts 312,322, the connecting portion 313,323 of weld part 314,324 and connection contact site 311,321 and weld part 314,324, and above each one 311,312,313,314 is positioned at same plane substantially.The last signal terminal 31 of first signal terminal set 30 is oppositely arranged with the contact site 311,321 of following signal terminal 32.The connecting portion 313 of last signal terminal 31 is roughly L-shaped, comprises vertical portion and horizontal part.The contact site 311 of last signal terminal 31 extends from the upper end of connecting portion 313 homonymy with the holding parts 312 that is form of bifurcation, and holding parts 312 is provided with hangnail 316, and it can form interference engagement with matrix 11.Contact site 311 extends downwards from holding parts 312 intermediate, inclined of bifurcated, and forms bending warpage upwards at free terminal, and forms downward contact protuberance 317 in the bending place of adjacent end.Bending place at L shaped connecting portion 313 extends to form weld part 314 downwards, be formed with the kink 315 that protrudes in plane, connecting portion 313 place with the horizontal part end of contact site 311 homonymies, L shaped connecting portion 313, this bending part 315 is that bending forms behind bar stock cutting by punching.The connecting portion 323 of following signal terminal 32 is also roughly L-shaped, but the vertical portion of last signal terminal 31 connecting portions 313 in its vertical portion is short, and horizontal part is than the horizontal minister of connecting portion 313.The contact site 321 of following signal terminal 32 tilts to extend upward from the last end profile of connecting portion 323, and forms downward bending warpage at free terminal, and forms contact protuberance 327 upwards in the bending place of adjacent end.Same end homonymy at the contiguous contact sites 321 of connecting portion 323 extends to form the holding parts 322 that is provided with hangnail 326, forms weld part 324 straight down and supports the kink 325 that contacts with matrix at the lower end of connecting portion 323.When

signal terminal

31,32 up and down be contained in matrix 11 corresponding when accommodating in the conduit 113, the connecting portion 313,323 of last signal terminal 31 and following signal terminal 32 is positioned at same plane and is set up in parallel, and contact site 311,321 lays respectively at the same end homonymy of connecting portion 313,323, the contact protuberance 317,327 of contact site 311,321 is oppositely arranged, and the vertical portion of the connecting portion 323 of following signal terminal 32 is just between the contact site 311 and bending part 315 of last signal terminal 31.

The shape of the upper and

lower signal terminal

41,42 of secondary signal terminal group 40 is roughly the same respectively at the upper and

lower signal terminal

31,32 of first signal terminal set 30, its difference only is weld part the 414, the 424th, extends to form downwards from the level end of L shaped connecting portion, and kink 415,425 then forms in the bending place of connecting portion.

The upper and

lower signal terminal

51,52 of the 3rd signal terminal set 50 is corresponding roughly the same respectively with the upper and lower signal terminal of the 4th signal terminal set 60 61,62, the vertical portion that the difference of itself and upper and

lower signal terminal

31,32 the is L shaped connecting portion vertical portion of signal terminal 32 down is shorter, horizontal part is longer, and the weld part the 514, the 524th of the 3rd signal terminal set 50, extends to form downwards from the horizontal part adjacent end place of connecting portion.In addition the difference of 50,60 of the 3rd, the 4th signal terminal set is identical with the difference of 30,40 of first, second signal terminal set.As shown in the figure, oneself development length of connecting portion separately of the holding parts of the last signal terminal of holding parts of the following signal terminal of each signal terminal set is long, and more close weld part, so retain strength is also relatively large, so comparatively speaking, last signal terminal more need be provided with kink in order to strengthen position-limiting action near the weld part place.In the icon, the 3rd time signal terminal 52 and the 4th time signal terminal 62 all are not provided with kink, but in the practical application, can increase the size of weld part influence according to the electronic cards insertion force one or more kinks are set.

In the above-mentioned signal terminal set 30,40,50,60, first, second
