Abstract
The utility model provides a card retreat structure of a memory card. An insulation seat is provided with a complex conductive terminal; a supporting arm is arranged at two sides of a central cottage grafting part in the same direction; after the complex conductive terminal is pushed into the insulation seat by the memory card, which can cause a complex contact of the memory card to be electrically connected with the complex conductive terminal which is corresponded with the insulation seat; one side of the insulation seat is pivot connected with a pushing block and is connected with an elastic element with the insulation seat; a guide bar at the front end of the elastic element can slide backwards and forwards in a guidance channel which is concave arranged at the surface of the insulation seat; the guide bar forms two locating points at the beginning of the guidance channel and a location part so as to enable the memory card to be pressed into a cycle twice and to pull the pushing block by using the elastic reset force of the elastic element to push the memory card outward to detach from a plug part of the insulation seat to form a condition of card retreat.
Description
One, technical field
The utility model relates to a kind of card-withdrawing structure of memory card, especially refer to that insulating base frame is articulated with one and passes piece, and link a flexible member with arm room, guide rod by the flexible member front end can be front and back slippage or location in the guide groove of edge edge pedestal, be pressed into a circulation and can see through secondary, make memory card break away from the Plug Division of insulating base frame.
Two, background technology
Computer technology is grown up with the speed of making rapid progress now, the development trend of its computer is also strong towards calculation function, the fast direction of speed strides forward, and be usually used in computer, electronic dictionaries etc. are used for expanding memory body, the networking card, religion is according to machine, scsi device is (as the high power capacity hard disc, scanner) is memory card, and the canonical form that memory is stuck on the computer is PCMCIA, general PCMCIAto SCSI, PCMCIA to IDE etc., all can make notebook computer be used the multiple interfare device of PC, in the middle of most of notebook computer, all support the ability of Plug and Play, even support to start shooting again and just can directly use hot plug (Hot Plug) function, and a MMC (Multi Media Card) is roughly still had in the market at present, CF (Compact FlashCard), SM (Smart Media Card), MS (Memory Stick), SD specifications such as (Secure DigitalMemory Card) can be for replacing.
In addition, general dealer all can set firmly a retreat-card device for taking the facility of user when pegging graft or withdrawing from memory card into account in plug socket, and existing retreat-card device is broadly divided into:
1, guide groove E is for being arranged with in passing piece B surface, utilize the support arm A1 of a flexible member C and insulating base frame A to form binding and pass piece B, and guide rod D is fixed in insulating base frame A side afterwards, can move with passing one of piece B by guide groove E, make guide rod D can in the guide groove E that passes piece B, be front and back slippage (as shown in Figure 6).
2, guide groove E is for being arranged with in passing piece B surface, utilize a flexible member C to be linked to the support arm A1 side of insulating base frame A and pass piece B, and guide rod D is the support arm A1 side of being fixed in insulating base frame A, can move with passing piece B by guide groove E, make guide rod D can in the guide groove E that passes piece B, be front and back slippage (as shown in Figure 7).
3, guide groove E is recessed in the support arm A1 surface of establishing insulating base frame A, and passing piece B is to utilize a flexible member C to be linked to insulating base A side afterwards, side then is positioned with a guide rod D in addition, guide rod D can move with passing piece B by guide rod D, even can be front and back slippage (as shown in Figure 8) in the guide groove E that passes piece B.
Yet such scheme still has following many shortcomings:
1, guide rod and flexible member are the separate type design, and above-mentioned two composed components are all very tiny; So, can form the difficulty in the assembling, and then can increase assembling man-hour, and cause cost to increase.
2, pass piece, flexible member and guide rod and be positioned the insulating base frame side, can increase the width of insulating base frame virtually, and can't meet that present computer trends towards gently, approaches, short and small trend.
3, composed component the more can form the increase of error and the assembly cost and the manufacturing cost of assembling, and the cost that is increased can cause price higher, makes consumer's purchase intention reduce, and then does not have the benefit on the industry.
So the global design of such scheme still remains necessity of further improveing.
Three, summary of the invention
The fundamental purpose of the utility model is guide rod and the flexible member one winding shaping that is by the flexible member front end, and can in the surperficial guide groove that is arranged with of insulating base frame, form slippage or positioning states, and then can push the state that is electrically connected of outside also disengaging of memory card and insulating base frame.
The secondary objective of the utility model is to be to reduce composed component, and except can significantly reducing cost, the error in the time of more can be because of the reduction reduction group structure of element produces.
For reaching above-mentioned purpose and structure, technological means that the utility model adopted and effect thereof, the preferred embodiment of drawing now with regard to the utility model illustrates that in detail its structure is as follows with function.
