Description
[technical field]
The present invention relates to a kind of electronic applications, refer in particular to the card connector that a kind of subcard of powering is pegged graft.
[background technology]
Mobile phone brings more facility to people's life, needs if common mobile phone will be realized the transmission of wireless signalOne SIM to be installed on mobile phone and realize communication function, along with the development of the communication technology, SIM at presentDevelop to second generation MiniSIM card, third generation MicroSIM card and the 4th generation NanoSIM card, everyA kind of size of electronic cards is all different, towards the development trend of miniaturization, for example, and MicroSIM cardLength and width be 15x12mm, the length and width of NanoSIM card are 12x9mm, have reduced by 30% area nearly.
Mobile phone in the market can only be inserted a kind of SIM, if manufacturer need to change to next model SIMBlock, need to change the electronic card coupler of grafting SIM simultaneously, if consumer is updated to electronic cards of future generation,As being updated to 4G from 3G, may need again to change mobile phone, make troubles to consumer thus.
Moreover, referring to No. 4536126th, the Japanese laid-open patent of on June 25th, 2010 bulletin, it is openA kind of card connector, has two kinds of different slots and pegs graft for different electronic cards, and wherein, a slot is for SIMCard is pegged graft, and another slot is pegged graft for SD card, and different slots is provided with different conducting terminals, thus,The card connector of this existing structure has increased integral thickness, is unfavorable for the miniaturization of electronic card coupler, alsoBe unfavorable for the ultrathin development of electronic product, meanwhile, different conducting terminals can only be pegged graft for a kind of electronic cards,Increase the manufacturing cost of electronic card coupler.
The card connector that thus, need to relate to a kind of functional need carrys out meeting the market requirement.
[summary of the invention]
Based on this, be necessary to provide a kind of multi-purpose card connector being easy to use.
The present invention is achieved by the following technical solutions: a kind of card connector, and can be for large and small extremely differentFew two kinds of electronic cards are pegged graft, it comprise lengthwise to the insulating body extending, be retained on many on insulating body bodyIndividual conducting terminal and shielding casing, this shielding casing has the upper shell and the side shell that are arranged on insulating bodyBody, and form the grafting space with an end opening with insulating body; Described card connector further comprises solidBe held in the shell fragment on insulating body, this shell fragment is provided with the guid arm protruding in grafting space, and this guid arm canBetween primary importance and the second place, swing back and forth, the upper shell punching of shielding casing is provided with elastic arm, this bulletProperty arm has the first protuberance and the second protuberance that protrude in grafting space, and relative the second protuberance of the first protuberanceAway from opening; In the time of primary importance, the guid arm of shell fragment is connected on the first protuberance of elastic arm, can be for littleElectronic cards is pegged graft, and in the time inserting large electronic cards, the second protuberance of this large electronic cards pushing tow elastic arm, makes guidingThe first convex portion of arm and elastic arm from, can insert large electronic cards.
Further improvement project: described the second protuberance closes on the opening part in grafting space.
Further improvement project: at lengthwise upwards, the more close grafting of relative the second protuberance of described the first protuberance is emptyBetween center line.
Further improvement project: described guid arm there is the lead segment of inclination and connect lead segment against section,And the first protuberance of elastic arm is to be connected in section.
Further improvement project: be describedly provided with and connect the arc section of lead segment and connect the flat of arc section against sectionFace section, this arc section can be pressed on kilocalorie, and described planar section is in order to be pressed on lesser calorie.
Further improvement project: described shell fragment is vertical setting mutually with elastic arm.
Further improvement project: described insulating body has sidewall, and shell fragment is retained on this sidewall, and sidewallBe provided with the curved portions that protrudes into grafting space, keep out the guid arm of shell fragment, anti-excessive deformation.
Further improvement project: the sidewall outside of described insulating body is provided with L shaped fixture block, the side of shielding casingHousing has the holding section being buckled on this L shaped fixture block.
The present invention also can be achieved through the following technical solutions: a kind of card connector, and can be for large and small extremely differentFew two kinds of electronic cards are pegged graft, it comprise lengthwise to the insulating body extending, be retained on many on insulating body bodyIndividual conducting terminal and shielding casing, this shielding casing has the upper shell being retained on insulating body, and with absolutelyEdge body forms the grafting space with an end opening; Described card connector further comprise be retained on insulation thisShell fragment on body, this shell fragment is provided with the guid arm protruding in grafting space, and the upper shell punching of shielding casing is establishedFlexible arm, this elastic arm has the first protuberance and the second protuberance that protrude in grafting space, and first is protrudingRelative the second protuberance of portion is away from opening; In the time that little electronic cards is inserted grafting space, little electronic cards is not connected to theOn two protuberances, the guid arm of shell fragment is connected on the first protuberance of elastic arm, in the time inserting large electronic cards,The second protuberance of this large electronic cards pushing tow elastic arm, the first convex portion that makes guid arm and elastic arm from, this is ledDraw arm in free state.
Further improvement project: described shell fragment is vertical setting mutually with elastic arm.
Beneficial effect of the present invention is as follows: by designing two groups of elastic constructions that cooperatively interact, in primary importanceTime, described guid arm is withstood by the first protuberance, and less stable grafting space is provided, when there being large electronic cards to insertFashionable, the second protuberance of meeting pushing tow elastic arm, makes the first protuberance of elastic arm separate with guid arm, makes guidingArm, in free state, provides a larger grafting space, and relatively existing card connector is conducive to peg graft simultaneouslyAt least two kinds of electronic cards, easy to use, and reduce manufacturing cost.
