Embodiment
Below with reference to each execution mode shown in the drawings, the utility model is described in detail.But these execution modes do not limit the utility model, the structure that those of ordinary skill in the art makes according to these execution modes or conversion functionally are all included in protection range of the present utility model.
According to Fig. 1 to Fig. 3, the utility model provides a kind of card connector 100, and it comprises insulating body 2 and is fixed on the some terminals 1 on insulating body 2.Described terminal 1 is fixed on the both sides of described insulating body 2 in two rows.Terminal 1 described in each is provided with the elastic arm 12 and weld part 13 that the fixed part 11, self-retaining portion 11 both side edges that are fixed on insulating body 2 inside extend to form respectively, described elastic arm 12 is formed with the contact site 123 in order to contact with docking electronic cards, described terminal 1 also has the bending guiding 14 bending to guide docking electronic cards under at least one side direction of elastic arm 12.
Described elastic arm 12 tilts upward and to extend and beyond the upper surface of described insulating body 2.Described elastic arm 12 self-retaining portion 11 extends thus makes the elastic arm 12 of some terminals 1 also be divided into the both sides of described insulating body 2 in two rows outside insulating body 2.The described elastic arm 12 being positioned at described insulating body 2 phase the same side aligns mutually along docking electronic cards direction of insertion.
Described elastic arm 12 has line part 121 that self-retaining portion 11 lateral margin linearly upwards extends and bends the broken line portion 122 upwards extended from line part 121.
Terminal 1 described in each is provided with two described elastic arms 12 that homonymy two ends, self-retaining portion 11 extend to form respectively.The described broken line portion 122 of these two described elastic arms 12 extends in opposite directions and is mutually connected, and makes whole terminal 1 form frame shaped, and this makes terminal 1 structure more stable, deformation is less likely to occur, extend the life-span of card connector 100, simultaneously also cost-saved, convenient during punch forming.In addition, extended by the inclination in broken line portion 122, the insertion of docking electronic cards can be guided further or extract, improving fluency during plug-in card.
Described bending guiding 14 bending under at least one side direction in described broken line portion 122 extends.In the vertical direction, the upper end of described bending guiding 14 higher than the upper surface of described insulating body 2, the lower end of described bending guiding 14 higher than described insulating body 2 lower surface and lower than the upper surface of described insulating body 2.Docking electronic cards will preferentially be conflicted when inserting the bending guiding 14 of elastic arm 12 lateral margin, and other parts of elastic arm 12 of can not conflicting.
In the present embodiment, the broken line portion 122 of two elastic arms 12 of terminal 1 described in each is all bent to form bending guiding 14 described in, and two described bending guidings 14 are arranged at side away from each other, two described broken line portions 122 respectively, make all can be guided during plug-in card.Certainly, if the both sides of described elastic arm 12 are equipped with bending guiding 14, or the side of described elastic arm 12 is provided with more than one bending guiding 14, or comprises above two kinds of designs simultaneously, also can reach the purpose of this utility model.
In the present embodiment, described bending guiding 14 is from the outside projection of elastic arm 12 lateral margin and be bent to form level and smooth cambered surface downwards, and docking electronic cards can slip into along cambered surface.
The part that two described elastic arm 12 phases that described contact site 123 is formed in terminal 1 described in each are connected, described contact site 123 in the vertical direction is higher than the upper surface of described insulating body 2.In the present embodiment, described contact site 123 is sphere, and level and smooth contact site 123 is more conducive to dock the insertion of electronic cards, also make with dock when electronic cards is conflicted more abundant.
