Description

A PCMCIA expansion card

technical field

The utility model relates to a notebook computer peripheral device, in particular to a PCMCIA expansion card.

Background technique

With the development of the computer industry, the use of USB interfaces is becoming more and more extensive, and more and more markets for peripheral devices that convert USB interfaces with various interfaces are maturing. Various PCMCIA (PERSONAL COMPUTER MEMORY CARD INTERNATIONAL ASSOCIATION, The abbreviation of the PC Memory Card International Federation, they have developed a credit card-like universal transfer card used on a notebook computer) The expansion card is a long card that is converted to a USB interface, as shown in Figures 1, 2, and 3, including Front loam cake 11, bottom case 12, back loam cake 13 and PCB component plate 14, because the length of bottom case 12, the thickness of front loam cake 11 is higher, when inserting main frame such as notebook computer, palmtop computer, socket and rear upper The cover part protrudes out of the host, occupying the external space of the host, and it is easy to damage the card, and it is easy to cause troubles due to frequent insertion and insertion when moving and carrying.

Utility model content

The utility model overcomes the above disadvantages and provides a PCMCIA expansion card with compact structure and convenient portability.

The technical solution adopted by the utility model to solve the technical problems is: a PCMCIA expansion card, including a front upper cover, a bottom case, a rear upper cover and a PCB component board, the front end of the PCB component board is provided with a PCMCIA socket, and the rear end A conversion socket is provided, the front upper cover buckles the front end of the PCB component board on the bottom case, and the rear upper cover buckles the conversion socket at the rear end of the PCB component board on the bottom case , the total length of the PCMCIA expansion card is less than or equal to the total length of the PCMCIA slot, and the thickness of the rear upper cover and the bottom case after fastening is less than the thickness of the PCMCIA slot.

The conversion socket may be a USB-A type socket.

The front end of the front upper cover can be punched into a "concave" shape, and the shape is adapted to the shape of the protruding upper surface of the PCMCIA socket at the front end of the PCB component board.

Both sides of the front upper cover may be provided with bent edges, and the bent edges extend backward beyond the rear end edge of the front upper cover.

The front end of the rear upper cover may be provided with a plug-in end protruding forward.

A hook can be provided at the front end of the "concave"-shaped structure of the front upper cover, and a buckle corresponding to the position of the hook is provided at the front end of the bottom case.

The utility model buckles the front end of the PCB component board on the bottom shell through the front upper cover to package the circuit and other media components on the PCB component board, and the rear upper cover covers the back of the PCB component board. The conversion socket at the end is buckled on the bottom case, and the conversion socket and some larger electronic components are packaged. Since the length of the PCB component board is less than or equal to 86 mm, the thickness of the rear upper cover and the bottom case after buckling Smaller than 10.5 mm, it can be completely embedded in the PCMCIA slot of the notebook computer, does not occupy the external space of the notebook computer, does not need to be pulled out from the notebook computer when carrying, and can be packed and taken away with the host computer, which increases the convenience of use sex and safety.

Detailed ways

As shown in Figures 4 and 5, the utility model comprises a front loam cake 21, a bottom shell 22, a rear loam cake 23 and a PCB component board 24, the front end of the PCB component board 24 is provided with a PCMCIA socket 241, and the rear end is provided with a The USB socket 242, the front upper cover 21 is made by punching and bending a thin-walled metal plate, and there are curved edges 211 on both sides, which are used to cover and fasten the two sides of the bottom shell 22, and the curved edges are backward The rear end edge is extended to make the rear end of the front upper cover 21 form a "concave" shape, thus ensuring a more stable fastening force with the bottom case 22, and the front end of the front upper cover is also stamped into a "concave" shape , and the shape is adapted to the protruding upper surface shape of the PCMCIA socket 241 at the front end of the PCB component board. The front end of the "concave" structure is provided with a hook 212. Bits (not shown in the figure) are hooked together to further increase the stability of the installation. The front upper cover buckles the front end of the PCB component board on the bottom shell for encapsulating the circuit and other media components on the PCB component board 24, while the rear upper cover 23 is made of plastic injection, Fasten the USB socket 242 at the rear end of the PCB component board 24 to the bottom case 22 to encapsulate the USB socket and some larger electronic components. The front end of the rear upper cover 23 is provided with a plugging end 231 protruding forward, and there is a groove (not marked in the figure) in the inner wall of both sides and the inner wall of the port, which is used to match the undercut of the edge of the bottom shell 22 223. Wherein, the length of the PCB element board 24 is less than or equal to 86 mm, which is less than or equal to the depth of the PCMCIA standard slot, and the thickness of the rear upper cover and the bottom case is less than 10.5 mm, which is less than the depth of the PCMCIA slot. thickness.

When the utility model is assembled, the PCB component board 24 is first placed in the bottom case 22; then the front upper cover 21 is installed, and the hook 212 at the front end of the upper cover 21 is fastened to the buckle position at the front of the bottom case B, Flanges 211 on both sides cover both sides of the bottom case 22; finally install the rear upper cover 23, first insert the plug-in end 231 at the front end of the rear upper cover 23 into the "concave" shape at the rear end of the front upper cover 21, and then Then it is buckled with the bottom case 22 to complete the assembly.

Because the utility model has shortened the length and reduced the height by adopting the above-mentioned structure, as shown in Figure 6, the two PCMCIA slots (5 mm thickness) or the single three types of PCMCIA slots inserted in the notebook computer In the groove (10.5 mm thickness), a large section is no longer exposed, so that the utility model can be completely built into the notebook, no longer occupying external space, and does not affect the appearance of the notebook computer, thereby realizing the installation of the USB port expansion card into the notebook computer. The effect of not extending the head out of the notebook computer, thereby meeting the expansion requirements of the notebook computer, which is light, thin and short, is also very convenient to carry around or plugged into the machine, has very good mobility, and at the same time well protects the utility model. New types are not damaged by collisions.

Wherein, the USB port can be replaced by a type A with a smaller width, or replaced by other small data ports with a thickness not exceeding 10.5 mm, so as to realize various interface conversion functions of the PCMCIA expansion card. The utility model can also be applied to other electronic devices with PCMCIA slots such as palmtop computers and desktop PCs.

In addition, the directional expressions such as "front", "rear", "front end" and "rear end" used in the above description are for the purpose of more clearly describing the technical solution of the application, and therefore should not be regarded as limiting the application .

The PCMCIA extension card provided by the utility model has been introduced in detail above, and concrete examples have been used to illustrate the principle and implementation of the utility model in this paper. The explanation of the above examples is only used to help understand the method and implementation of the utility model Its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the utility model, there will be changes in the specific implementation and application scope. New types of restrictions.
