Abstract

A PCMCIA component such as a modem is connected to a PDA by means of a component interface that eliminates the need for a “sled”. The interface includes 68 or more female sockets (for full PCMCIA) or 50 female sockets (for mini-PCMCIA) on the PDA and compression-loaded male pins on the component that electrically engage sockets on the PDA. The PCMCIA component is held to the PDA without using a sled.

Claims

1. A system, comprising:

at least one personal digital assistant (PDA);

at least one of;

fifty (50) female sockets, and sixty eight (68) female sockets, on the PDA, the female sockets being electrically compatible with personal computer memory card interface architecture (PCMCIA) requirements, the sockets being connected to processing components within the PDA;

at least one component detachably engaged with the PDA; and

plural compression-loaded male pins on the component engaging respective female sockets on the PDA without the need for a sled.

2. The system of claim 1, further comprising at least one guide pin on the component.

3. The system of claim 1, further comprising at least one abutment on one of:

the PDA, and the component, configured for engaging a catch hole on the other of;

the PDA, and the component.

4. The system of claim 1, wherein the component is one of:

a wireless PCMCIA modem, a pager, a radio tuner, TV tuner, a video adaptor, a barcode scanner, and a battery.

5. The system of claim 1, comprising seventy two (72) sockets on the PDA.

6. The system of claim 1, wherein the pins are pogo pins disposed on a plastic substrate.

7. The system of claim 1, wherein the sockets are arranged in a 4×

17 grid.

8. The system of claim 3, wherein the abutment is on the component and the catch hole is on the PDA.

9. A personal computer memory card interface architecture (PCMCIA) component, comprising:

a component substrate; and

plural compression-loaded male pins on the substrate, the pins being engageable with respective female sockets on a PDA.

10. The component of claim 9, further comprising at least one guide pin on the component.

11. The component of claim 9, further comprising at least one abutment on one of:

the PDA, and the component, configured for engaging, in an interference fit, a catch hole on the other of;

the PDA, and the component.

12. The component of claim 9, wherein the component is one of:

a wireless PCMCIA modem, a pager, a radio tuner, TV tuner, a video adaptor, a barcode scanner, and a battery.

13. The component of claim 9, comprising at least sixty eight pins.

14. The component of claim 9, wherein the pins are pogo pins disposed on a plastic substrate.

15. The component of claim 13, wherein the pins are arranged in a 4×

17 grid.

16. A method for engaging a component with a portable computer, comprising:

providing at least sixty eight sockets on one of;

the component, and computer;

providing plural pins on the other of;

the component, and the computer, the pins being compression loaded such that when the component and computer are engaged the pins are biased against the sockets; and

holding the component onto the computer without using a sled.

17. The method of claim 16, wherein the holding act is undertaken using at least one abutment on one of:

the component, and the computer, and at least one hole on the other of;

the component, and the computer, the abutment engaging the hole in an interference fit.

18. The method of claim 16, wherein the computer is a PDA and the component is a PCMCIA component.

19. The method of claim 16, wherein the pins are pogo pins mounted on a resilient plastic substrate.

20. The method of claim 16, further comprising providing at least one guide pin on the component.
