Background technology

Come into vogue from 3C consumer products such as digital camera, PDA, MP3 walkmans, also driven the flourish of flash memory, derive the memory of various different sizes.With present modal memory specification, always total SM (SmartMedia; Smart media storage), xD-Picture card (super digital image memory), CF (Compact Flash Card; The compact flash memory), MD (Micro DriveCard; Microdrive), MS memory stick (Memory Stick), MS Duo (dual memory stick), MS Pro (Memory Stick Pro; The front memory stick), MS Pro Duo (Memory Stick Pro Duo; Positive dual memory stick) and SD (Secure Digital; The protection digital storage), MMC (MultiMediaCard; The multimedia memory), therefore, the Duo Shuo All-in-One card reader specification of also following these memories designs on the market, because 3C digital commodities volume is more and more littler, memory vendor is released the littler memory of volume again one after another, mini SD, RS-MMC that comprises the Duo series that extended out by MS, extended out by SD, MMC specification and up-to-date TransFlash, these micro memories all expose on market one by one with littler, more miniature volume.Wherein, the flash memory that TransFlash is minimum in the world now especially, go up half than the SIM card of existing mobile phone is also little, but but can store numerical data up to 128MB, and compatible fully with the SD memory that the consumer is familiar with, only need just can from card reader, read or write great mass of data fast through the adapter of built-in, the computer document that comprises high picture element photograph, high-quality MP3 music even individual, all accesses everywhere.It is that the mode of terminal with Insert Molding directly is fixed in the housing of adapter that general existing adapter is made.But this kind mode production capacity is low and cost is higher.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, easy to assembly, flash memory adapter of improving production capacity, reducing cost.

The utility model comprises upper shell, connector and lower house; Connector is made up of loam cake, lower cover and terminal with cusp structure; The central portion of loam cake has for cusp structure on the terminal and wears several fixing cusp fit structures; The terminal two ends form shell fragment and golden finger respectively; Loam cake and lower cover cover and the clamping fixed terminal mutually, and connector is fixed on the lower house with the ultrasonic waves riveted, combines with upper shell more at last.

Wherein:

Upper shell is made into the form of SD card; In both sides and the lateral margin of rear end be respectively equipped with several breach.

Cover on the connector and be provided with guide pillar.

Following the covering of connector is provided with and the corresponding guide pillar of guide pillar hole.

The both sides of connector loam cake have downward coupler construction.

The loam cake both sides of connector have several welding wire casings.

Be covered with under the connector and the corresponding buckle structure of loam cake upper clamping hook structure.

Lower house is made into the form of SD card, its front end has several connecting holes that passes for the terminal golden finger, and being provided with several location jubes that can be used to place and separate the bonder terminal golden finger corresponding to the connecting hole position in lower house inside, the lower house central portion is provided with draw-in groove and several boss of corresponding and ccontaining connector.

Lower house is provided with weld bond corresponding to the position that covers the weld bond groove on the connector.

On cover the weld bond of weld bond groove and lower house with the ultrasonic waves riveted.

Because the utility model comprises upper shell, connector and lower house; Connector is made up of loam cake, lower cover and terminal with cusp structure; The central portion of loam cake has for cusp structure on the terminal and wears several fixing cusp fit structures; The terminal two ends form shell fragment and golden finger respectively; Loam cake and lower cover cover and the clamping fixed terminal mutually, and connector is fixed on the lower house with the ultrasonic waves riveted, combines with upper shell more at last.Connector is assembled in the lower house draw-in groove, and with ultrasonic waves and lower house riveted, prevents that the terminal of connector from deviating from the draw-in groove of lower house because of longitudinal stress; Combine with upper shell more at last.Not only simple in structure, easy to assembly, and improve production capacity, reduce cost, thereby reach the purpose of this utility model.

Embodiment

As shown in Figure 1 and Figure 2, the utility model flash memory (Transflash) adapter comprises upper shell 10, connector 20 and lower house 30.

Upper shell 10 is made into the form of SD card, in both sides and the lateral margin of rear end be respectively equipped with several breach 11.

As shown in Figure 3, Figure 4, connector 20 is made up of loam cake 21, lower cover 22 and terminal 23.

The appropriate location of loam cake 21 is provided with guide pillar 21a, and the both sides of loam cake 21 have downward coupler construction 21b and several welding wire casings 21c, and loam cake 21 central portions have several cusp fit structures 21d.

Lower cover 22 is provided with and the corresponding guide pillar of guide pillar 21a hole 22a and and the corresponding buckle structure 22b of coupler construction 21b.

Terminal 23 two ends form shell fragment 23a and golden finger 23b respectively.Shell fragment 23a end forms the cusp structure 23al corresponding to cusp fit structure 21d.

Upper and

lower cover

21,22 covers mutually so as to clamping fixed terminal 23, and cusp structure 23al is worn be fixed in the cusp fit structure 21d, the part golden finger 23b of terminal 23 is exposed to outside the connector 20.

As Fig. 1, Fig. 2, Fig. 5, shown in Figure 6, lower house 30 is made into the form of SD card, its front end has several connecting holes 31 that passes for terminal 23 golden finger 23b, and is provided with several location jube 31a that can be used to place and separate connector 20 terminals 23 golden finger 23b in lower house 30 inside corresponding to connecting hole 31 positions.Lower house 30 central portions be provided with corresponding and ccontaining connector 20 draw-in groove 32, have the socket 33 on plastic cement surface and between draw-in groove 32 and socket 33, be used for placing the boss 34 of terminal 23 shell fragment 23a.Lower house 30 is provided with weld bond 35 corresponding to the position of welding wire casing 21c on connector 20 loam cakes 21.

As Fig. 5, shown in Figure 6, connector 20 is assembled in lower house 30 draw-in grooves 32 and the socket 33, because the plane of terminal 23 shell fragment 23a positions is lower than the plastic cement surface of the socket 33 of lower house 30 rear end central portions, the shell fragment 23a of terminal 23 is positioned on the boss 34 of lower house, and, cause terminal 23 to get loose when preventing plug-in card with the loam cake 21 of connector 20 and the shell fragment 23a of boss 34 tight clamping terminals 23.The weld bond 35 of welding wire casing 21c and lower house 30 on connector 20 loam cakes 21 can be with connector 20 and lower house 30 with the ultrasonic waves riveted, prevents that the terminal 23 of connector 20 from deviating from the draw-in groove 32 of lower house 30 because of longitudinal stress; Combine with upper shell 10 more at last.

In sum, the utility model comprises upper shell, connector and lower house; Connector is made up of loam cake, lower cover and terminal, and is not only simple in structure, easy to assembly, improved production capacity and reduced manufacturing cost.
