The utility model can achieve the effects of durability, simplified structure and heat dissipation.
Description
[technical field]
The utility model is about a kind of electric connector, particularly about a kind of smart card connector.
[background technology]
See also Fig. 1 and Fig. 2, it is a kind of existing card connector, be to make smart card (as phonecard, fiscard, credit card etc.) insert connect, it is provided with a pedestal 10 and two and arranges the terminal 20 of being located at this pedestal 10, wherein this pedestal 10 is provided with an end face 11 and a bottom surface 12, be the draw-in groove 13 that forms a ccontaining smart card in it, this draw-in groove 13 is provided with one and inserts mouth 14; This each terminal 20 is provided with contact site 21 and pin portion 22, and this contact site 21 is positioned at this draw-in groove, and it is convex arc shaped and protruding end face 11 to pedestal, and the pin portion 22 of this two rows terminal inserts mouthful 14 1 sides and correspondence respectively certainly and inserts the bottom surface 12 that a side of mouth 14 is stretched out pedestal.
Moreover the use of smart card is more and more universal, and family uses as set-top box has been commonly, and set-top box can be plugged a smart card in the use for a long time, so more is added with radiating requirements.
Existing smart card connector such as TaiWan, China application case number 095216234 is that heat dissipation design is arranged, it covers on pedestal and adds a fin, its roughly prior on cover and offer a window, fix a fin in last covering again, this fin is provided with a depressed part and is absorbed in this window, so setting does not reach the simplification effect, increases cost because of adding fin on the contrary.
Because the smart card connector in the use, card reader only reads and discerns as data smart card, the smart card connector need not have ground connection and prevent electromagnetic interference (EMI), need not to be provided with a metal shell, so present existing loam cake all is to adopt the plastic cement loam cake, there is no any type of metal top cover design.
The main cause that existing smart card connector does not design metal top cover is cost factor, because the manufacturer generally believes the inevitable cost serious offense of metal material plastic cement material, yet this kind cognition is incorrect, because the plastic cement loam cake is resisted the elastic force of 8 terminals and is prevented that smart card from producing high hot institute and causing plastic deformed for sufficient intensity is arranged, the plastic cement loam cake must have enough thickness, need 1.5mm approximately, so material cost is not low, and because the plastic cement coverage of smart card connector is very big, so mould can be arranged the die cavity limited amount of establishing, the limited amount that once can penetrate when plastic rubber ejaculate molding, processing cost improves relatively.
Moreover the proportion of plastic material is 1.5, and thickness needs 1.5mm approximately, so whole plastic cement loam cake does not arrive compact effect, and the no thermolysis of plastic cement loam cake itself, need to cooperate a fin then more to increase cost.
