Abstract

The utility model relates to an improved computer expander which comprises an expansion card frame which is a frame body arranged on a computer plate. The opening point of the frame is corresponding to an expansion card groove, and the inner end of the frame is provided with a connection pin and connected with a host machine. The utility model also comprises expansion connection points arranged on the computer plate in the expansion card frame and provided with expansion connection wires to be connected with an expansion joint. In addition, the utility model comprises an expansion joint which is arranged on the edge part of a computer. The circuit can be switched on, with the help of the contact between a card connection point arranged correspondingly in the bottom part of an expansion card and the expansion connect point when the card connection point is inlaid, and the expansion joint can be directly connected externally with expansion objects.

Description

A kind of improved computer expanding unit

Expansion card is indispensable element in computer, considers volume of computer own and cost, and some outfits are difficult to setting available in all varieties.But, through external expansion card, the function of computer is enlarged, so, as red blossoms and green leaves, can complement each other between expansion card and computer.

The kind of expansion card presents polynary according to its effect difference, internationally also will be standardized, be so-called pcmcia card (Personal Computer Memory CardInternational Association), storage card, datafax (FOX/MODEM) card, networking card (LANCARD) etc. as is known adopt the mode of pcmcia card exactly.

Known laptop is when using pcmcia card, shown in Fig. 1 and Fig. 2 datafax.In computer one side, open a slotted eye 10, and with an adapter 20, link a syringe needle 30, this syringe needle 30 promptly is plugged in the pin hole in pcmcia card 40 outsides, and pcmcia card 40 then interlocking and has circuit to link (detailed in Fig. 2) in defaulting in the expansion card frame 50 of computer inside.Simultaneously, be external via phone support RJ-11 joint 60 commonly used again, therefore, toss about in bed to join, can be rated as loaded down with trivial details.Tracing it to its cause, is because the RJ11 joint is thicker than expansion card at present, can't directly be plugged on the expansion board, therefore, must use and carry very inconvenience by adapter 20 switchings, and the someone is referred to as " mouse tail ".Simultaneously, transfer when too many, the bad situation of wiring often takes place,, still continue to use this kind mode, can't but be a shortcoming in today that the research and development of products of information industry is maked rapid progress.

The utility model is the concrete technology contents that further discloses this case, at first sees also diagram.Fig. 1 is known expansion schematic perspective view, and Fig. 2 is known expansion schematic perspective view, and Fig. 3 is the three-dimensional exploded view of this case, schematic perspective view when Fig. 4 implements for this case.

As shown in Figure 3, the utility model is by an expansion card frame 1, and some expansion contact 2, one extending connectors 3 and expansion card 4 are formed.

Wherein, expansion card frame 1 is for being located at the framework of computer plate, and opening is outside, is convenient to expansion card 4 and inserts.And its inner has and somely connects pin and link computer motherboard (this also is currently used for prior art, does not intend giving unnecessary details).

Expansion joint 2 is provided in a side of on the computer plate in the aforementioned expansion card frame 1, and its purpose is to supply with card contact 41 contacts of the expansion card corresponding setting in 4 bottoms, so that connect circuit.Expansion joint 3 and card contact 41 are able to flexure strip and make.Simultaneously, have external function,, and be attached in the expansion joint 3 so expansion contact 2 is drawn expansion wiring 21 respectively for making it.

Expansion joint 3 is a solid content, is located on the edge of computer, links with expansion wiring 21.In addition end is for the external connector intercalation, and shown in this case embodiment is to take the RJ-11 joint style, but during actual enforcement, must look the thickness of notebook computer and does different designs.

Expansion card 4 is known pcmcia cards, visual function demand and different, as can be memory card, datafax card, networking card ... Deng.The one end then have with aforementioned expansion card frame 1 connect the corresponding pin (, failing to illustrate) that connects of pin because of projection relation.And the utility model difference is corresponding to aforementioned expansion contact 2 places, card contact 41 to be set in its bottom, and this card contact 41 has the external contact of circuit and former expansion card to have circuit to link, and can contact after feasible the setting, and then circuit is linked.

When the utility model is implemented, please consult Fig. 4 again, when expansion card 4 inserts from the default draw-in groove of computer periphery, and set in the expansion card frame 1 time, connect pin and promptly form path, and card contact 41 is promptly touched expansion contact 2, and after expansion wiring 21 is connected to expansion joint 3, and then can be external.

Therefore because its thickness of laptop is far above expansion joint 3, so on being provided with, be not subject to known must be via the pin that connects of expansion card 4, and exempt the setting of adapter, and export via other side expansion joint 3.Therefore, also can make expansion card 4 can not connect the impaired bad situation of connection that causes of pin, also not have and carry inconvenient phenomenon, can be described as one of expanding unit and improve greatly because of grafting makes.

Present embodiment is a kind of of preferred embodiment, the change of all parts or modification and come from this case technological thought and for be familiar with this skill the people was easy to know by inference, do not take off the category of this case patent.

In sum, no matter the utility model is with regard to purpose, and means and effect are all showing that it is different from known technical characterictic, is that it is at first created and is suitable for practicality, also meets the patent requirement of utility model.
