Description

Switching electronic cards device

The relevant a kind of electronic cards of the utility model refers to that especially a kind of portable computer that is applied to is to expand the switching electronic cards device of its function.

No matter portable computer is at function or aspect of performance, all very approaching with corresponding desktop computer at present.Usually, the cabinet inside of desktop computer all is reserved with Extended Spaces, and grafting daughter board or subsystem on the motherboard of user Ke Yi individual demand in cabinet expand various functions, and for example, grafting network interface card or modulator-demodulator are realized the networking message transmission.Portable computer is then different, because portable computer must have characteristics easy to carry and use, its system design is very compact and light and handy, and is difficult to reserve the space of expanding usefulness for function in internal system, so the expansion of its function is easy to realize not as desktop computer.Present solution normally utilize the switching electronic cards device of pegging graft to realize, and these electronic cards all meets PCMCIA (Personal Computer Memory Card International Association, personal computer memory card association) standard.And along with development of electronic technology, electronic cards also begins to use on other portable electronic product, thereby the various simple switching electronic cards devices that are suitable for are provided, and has become the exploitation direction of portable electronic product production firm.

Shown in No. the 5th, 562,504, related art such as the United States Patent (USP), see also Fig. 1, it has disclosed the structure that a kind of utilization switching electronic cards 90 is connected with an outside rj connector 92.Because first kind PCMCIA standard electric subcard is thinner, can't the rj connector socket directly be set in the end of a standard electric subcard, realize being connected with the mode that 92 of rj connectors are set up an adaption layer 2 adapter 91 so just adopt in the prior art in switching electronic cards 90, connection status sees also shown in Figure 2.But, in the prior art, need to use more additional member, cause cost too high, also be not easy to the user and carry and use, and also too complicated because of bang path, cause destabilizing factor to increase.

Another kind of existing structure shown in No. 332, sees also Fig. 3 as United States Patent (USP) the 5th, 773, and it also discloses a kind of switching electronic cards 95 of being connected with an outside rj connector 96 of being used for.The change-over terminal of this switching electronic cards 95 directly is provided with the socket 97 of rj connector, just can realize being connected so it needn't increase adaption layer 2 adapter with 96 of rj connectors again in switching electronic cards 95, so it is relatively simple for structure, cost is lower and performance is more stable.But, the PCMCIA electronic card standards provides three types of dimensionss at present, the length and the width of these three types of electronic cards are identical, thickness is respectively 3.3mm, 5.0mm and 10.5mm, but all adopt the connector of 68 pins, so thin electronic cards can be used on thick electronic cards socket connector, but thick electronic cards cannot be used on thin electronic cards socket connector.The thickness of switching electronic cards 95 as shown in Figure 3 is thicker, only be suitable for using on the computer of the socket connector that meets the 3rd class PCMCIA electronic card standards (a kind of two electronic card couplers that the electronic cards socket stacks), thereby the scope of application is narrow.

The purpose of this utility model is to provide a kind of switching electronic cards device, and simple, the stable performance of this switching electronic cards device construction can a plurality of aerial lugs of a card switching, and can with the multiple standards compatibility.

For achieving the above object, the utility model adopts following technical scheme: switching electronic cards device is formed by electronic cards and with the adapter that this electronic cards one end utilizes hyoplastron to fix.Wherein, the width of electronic cards and gauge meet more slim electronic card standards specification, but length is not less than standard specification, and this electronic cards is provided with docking port at an end of not establishing adapter; Adapter then has the size bigger than the thickness of electronic cards, and its free elongated end is formed with the switching socket; Contain circuit board in electronic cards and adapter inside, some electronic installations are set on this circuit board, its corresponding switching spigot be provided with can be matched with aerial lug adaptor connector, corresponding docking port place then is provided with the butt connector that can connect with the electronic card coupler of computer inside.

When using this switching electronic cards device, electronic cards is inserted in the computer (or other electronic product), the electronic card coupler of butt connector and computer inside is connected, adapter is then stayed the computer outside, aerial lug can be connected with the adaptor connector in the adapter, thereby realize and being connected of computer internal circuit.

Owing to adopt such scheme, simple, the stable performance of this switching electronic cards device construction, easy to use, can a plurality of aerial lugs of a card switching, and can with a plurality of electronic card standards compatibilities.
