Description

Card connector detect module

Technical field

The utility model relates to a kind of module that detects of card connector, when referring to especially in storage card pushes insulating base frame, detecting terminal that can be by detecting module and earth terminal is set up in parallel and conflict with the default contact of storage card has the short circuit of preventing and can detect simultaneously whether storage card locatees and the function of ground connection with this.

Background technology

Flash memory is just strong because of calculation function since coming out, speed is fast, the expandability height, the characteristic that high storage density etc. are charming, in many portable devices, gradually replace EEPROM (voltage cancelling programmble read only memory PROM) or battery powered internal memory, because semiconductor technology progresses greatly day by day at present, the storage density of flash memory and transmission speed have the growth of advancing by leaps and bounds especially, therefore flash memory directly replaces traditional Storage Medias such as hard drives especially in many application, because flash memory has above-mentioned all multi-functional and characteristic, just there is relevant dealer to utilize flash memory and develops and all types of storage cards, as typical storage card is PCMCIA (Personal Computer memory Card International Association), roughly still has MMC (Multi Media Card) at present on the market, CF (Compact Flash Card), SMC (Smart Media Card), MS (Memory Stick), SD (Secure Digital Memory Card), XD specifications such as (xD-Picture Card) can be for replacing, and this type of storage card promptly has been subjected to consumers in general's favor since coming out, and become a kind of indispensable tool using that is almost, and employed relatively card connector is also with increase in demand.

And announcing No. 537535 " miniature cards electric connector plug-in card arrangement for detecting ", the card connector of prior art such as TW see also Fig. 7, shown in 8, be the stereo appearance figure of prior art and the stereo appearance figure of detecting terminal and earth terminal, by being clear that among the figure, prior art is provided with terminal base A1 in insulating body A rear end, this terminal base A1 is preset with terminal hole A11 in a row, plug the location respectively for multi-conducting terminals A2, in the location one detecting terminal B that pegs graft of a terminal hole A11 wherein, and a parallel earth terminal C of being separated by pegs graft among the slot A12 above summary, this detecting terminal B and earth terminal C respectively contain a contact-segment B1, C1, and in away from contact-segment B1, other side of C1 is extended with the welding section B2 of opposite lateral bending direction, C2; Compress the relative same contact of contact miniature cards thus when detecting terminal B and contact-segment B1, the C1 elasticity of earth terminal C, then mutual conduction to each other makes the detecting terminal become ground state, so that the detecting judgement signal of plug-in card location to be provided.

Though yet the module that detects of above-mentioned card connector has had the function that signal is judged in detecting, still has following defective:

(1) the earth terminal C of prior art is positioned at slightly place, top of detecting terminal B, therefore easily after using a period of time, the elastic-restoring force of earth terminal C reduces and return positively, make the contact-segment C1 of earth terminal C when using, contact at detecting terminal B, therefore cause situation of short circuit to produce.

(2) the earth terminal C of prior art is positioned at slightly place, top of detecting terminal B, therefore makes the thickness of connector integral body increase, and not only causes the increase of manufacturing cost easily to cause the waste in space.

(3) the detecting terminal B of prior art and earth terminal C are the differing heights setting, make add man-hour must be earlier with multi-conducting terminals A2 and after detecting terminal B and being plugged at terminal base A1, again earth terminal C is plugged at terminal base A1, therefore must divide secondary operations, and then cause the increase of manufacturing cost and machining period.

So, how to solve the above problems and defective, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Summary of the invention

Main purpose of the present utility model is to overcome the deficiencies in the prior art and defective, a kind of module that detects of card connector is proposed, utilize insulating base frame to be provided with and detect module, and the detecting terminal and parallel being arranged side by side in the tripod position of earth terminal that detect module can prevent that situation of short circuit from producing, after making that storage card pushes insulating base frame, the default contact of storage card contacts at detecting terminal and earth terminal simultaneously, and then reaches the purpose of detecting and ground connection.

For reaching above-mentioned purpose, the utility model provides a kind of module that detects of card connector, include insulating base frame and detect module and form, and insulating base frame central authorities base portion two sides have extended a support arm in the same way, make two support arms form a butt joint space, and on insulating base frame, be equipped with the complex conduction terminal, and after making the complex conduction terminal push the butt joint space of insulating base frame in storage card, can make complex conduction terminal corresponding on the default plural contact of storage card and the insulating base frame form electrically connects, wherein, the module that detects that is arranged in the aforementioned dielectric pedestal has detecting terminal and an earth terminal at least, and detecting terminal and earth terminal is parallel is arranged side by side in the tripod position.
