Abstract
The utility model relates to a user identity identifying module (SIM) card connector, comprising an insulating shell and a plurality of conductive terminals. Each conductive terminal comprises a first connecting portion and a second connecting portion, both of which are connected by a bending portion and are positioned on the same side of the bending portion. A lock joint structure is provided between the first connecting portion and the second connecting portion. The conductive terminal of the SIM card connector having the above structure is adopted; via the clip connection of the first connecting portion and the second connecting portion, the conductive terminal is caused to bear a certain preloading force. In this way, a compression joint portion is not needed to be arranged on the insulating shell to maintain the preloading force of the conductive terminal, which reduces the height of the insulating shell; therefore, the height of the SIM card connector is reduced. Simultaneously, in the assembling process of the conductive terminal of the SIM card connector having the above structure and the insulating shell, pushing the first connecting portion and the second connecting portion is reduced, which causes the conductive terminal to bear a certain preloading force procedure, which facilitates the assembling and improves the assembling efficiency.

Embodiment
According to Fig. 3 to Fig. 5, provide preferred embodiment of the present utility model, and described in detail below, enable to understand better architectural feature of the present utility model and function, characteristics.
Consult Fig. 3, sim card connector of the present utility model comprises an insulation shell 3, and this insulation shell 3 is provided with accepting groove 31; Plurality of conductive terminals 4 is housed in the accepting groove 31 of insulation shell 3.
Fig. 4 and Fig. 5 have shown the conducting terminal 4 of sim card connector among Fig. 3.This conducting terminal 4 roughly takes the shape of the letter U, and comprises a weld part 41, one first connecting portion 42, one kinks, 43, one second connecting portions 44 and contact sites 45.First connecting portion, 42 corresponding contact sites 45 are provided with first through hole 421.Weld part 41 is provided with second through hole 411.Second connecting portion, 44 both sides are extended a pair of flank 46,47, the first connecting portions 42 corresponding flanks 46,47 positions and are formed the first snapping portion 48 and the second snapping portion 49, withhold on described flank 46,47.
Link to each other by kink 43 between first connecting portion 42 and second connecting portion 44, and be positioned at the homonymy of kink 43.First connecting portion 42 extends weld part 41 with the relative other end that kink 43 links to each other end.Weld part 41 is long plate shape, and it can utilize surface mount technology to be welded on the printed circuit board (PCB) (figure does not show).Second connecting portion 44 is after extending a segment distance on the plane that is basically parallel to first connecting portion 42, extend the contact site 45 that roughly is spoonful shape again, in order to electrically to contact with the conducting surface of SIM card, after conducting terminal 4 is assembled into insulation shell 3, contact site 45 will protrude the interface 32 of insulation shell 3.
Consult Fig. 4 and Fig. 5, the first snapping portion 48 has an extension 481 and and bends the attaching part 482 that extends from extension 481 one, and attaching part 482 is withheld on flank 46.Similarly, the second snapping portion 49 has an extension 491 and and bends the attaching part 492 that extends from extension 491 one, and attaching part 492 is withheld on flank 47.So just make conducting terminal 4 self have certain preload force.Therefore, just not needing to be provided with extraly described in background technology a pressure contact portion does not keep preload force for insulation shell 3, has reduced the height of insulation shell 3, and then has reduced the height of sim card connector, makes further miniaturization of sim card connector.Simultaneously, in the assembling process of conducting terminal 4 and insulation shell 3, omitted the step of pushing first connecting portion 42 and second connecting portion 44, made things convenient for assembling, thereby improved assembling efficiency.
Consult Fig. 4 and Fig. 5, first connecting portion, 42 corresponding contact sites 45 are provided with first through hole 421, and when SIM card was inserted, contact site 45 stressed moving down were offered first through hole 421 and just prevented that contact site 45 from touching first connecting portion.Weld part 41 is provided with second through hole 411, and when weld part 41 lower surfaces were fixed on the circuit board by fusing tin ball, liquid tin can overflow to the upper surface of weld part 41 from second through hole 411, has increased the fastness of welding.
Flank 46,47 respectively has the relative side 462,472 away from kink 43 with, side 461,471 of a close relatively kink.The extension 481 of the first snapping portion 48 is positioned at 461 places, side of the close relatively kink 43 of flank 46, and the extension 491 of the second snapping portion 49 is positioned at relative 472 places, side away from kink 43 of flank 47.That is to say that the first snapping portion 48 is near after kink 43 1 ends extend upward, to away from kink 43 direction bending extensions.The second snapping portion 49 is after extend upward away from kink 43 1 ends, near kink 43 direction bending extensions.The benefit of She Zhiing is like this, after conducting terminal 4 is integrally formed, second connecting portion 44 is rotated a certain angle, just can be so that flank 46,47 buckles into snapping portion 48,49.
More than describing only is a kind of embodiment of the present utility model, can also make some modifications or variation according to principle of the present utility model.For example, can suitably select the quantity of snapping portion and flank, the foregoing description is selected two, also can select for example four.The position configuration relation of a plurality of snapping portions and flank also can be made suitable variation.The described flank of the foregoing description is that the side from first connecting portion extends, and corresponding snapping portion to be side from second connecting portion extend and snap onto on the flank.As a same reason, extend flank, extend corresponding snapping portion, snap onto on the flank and also be fine from the side of first connecting portion from the side of second connecting portion.In addition, two snapping portions can be symmetrical arranged, and also can be crisscross arranged, and promptly the distance between two snapping portions and the kink does not wait.And the snapping direction of flank also can suitably change, for example promptly can as above state the described reverse snapping of embodiment, also snapping in the same way, after promptly two snapping portions all extend upward from close kink 43 1 ends, to away from kink direction bending extension, or two snapping portions are all after extend upward away from kink one end relatively, near kink direction bending extension.
Adopt sim card connector of the present utility model, its first connecting portion and second connecting portion are by mutual crimping, make conducting terminal have certain preload force, therefore, just do not need to be provided with extraly described in background technology a pressure contact portion keeps preload force to insulation shell, reduce the height of insulation shell, and then reduced the height of sim card connector, made further miniaturization of sim card connector.Simultaneously, in the assembling process of conducting terminal and insulation shell, omitted the step of pushing first connecting portion and second connecting portion, made things convenient for assembling, thereby improved assembling efficiency.
Above-described; it only is preferred embodiment of the present utility model; be not in order to limit scope of the present utility model; be that every simple, equivalence of doing according to the claims and the description of the utility model application changes and modification, all fall into the claim protection range of the utility model patent.
