Embodiment

As shown in Figure 3 and Figure 4, in first embodiment of metal terminal of the present utility model, the pin 13 that metal terminal 10 comprises link 11 and is used for pegging graft with circuit board also comprises being arranged on metal terminal middle part and the angled fin 12 of metal terminal axis.Link 11 is positioned at the front end of connector, for cylindrical, is used for being connected with outside.Pin 13 is provided with the hole of pinprick shape, and the both sides in described hole are to outer lug, and are reliable with being connected of circuit board when guaranteeing to insert circuit board.In first embodiment of metal terminal of the present utility model, fin 12 is two, places the both sides at metal terminal 10 middle parts, opens to relative direction, and fin 12 is 30 degree～90 degree with the axis angle of metal terminal 10, in the present embodiment, is 90 degree.

With reference to figure 5, when metal terminal 10 cooperates with the plastic cement main body 20 of connector, fin 12 concora crush are on the platform 21 of plastic cement main body 20, at the pin 13 of metal terminal 10 when direction shown in the arrow 40 is pressed into circuit board 30, referring to Fig. 7, the external force that metal terminal 10 is subjected to can be transferred on the platform 21 by fin 12, because the contact area of fin 12 and platform 21 is big, can prevent that plastic cement main body 20 from causing plastic cement bulk deformation and cracking because of local pressure is excessive, prevent also that simultaneously metal terminal 10 from scurrying on excessive because of stressed.
