The covering means 37 includes a first shield 38 installed on a side of the circuit board 32 and a second shield 40 installed on the other side of the circuit board 32 for combining with the first shield 38 so as to cover the connector 36. The first shield 38 and the second shield 40 can be made of polyethylene (PE) or polypropylene (PP) and can be one-piece moldings. The first shield 38 includes two first holes 42, a second hole 44, two first pins 46, and a second pin 48. The second shield 40 also includes two first holes 42, a second hole 44, two first pins 46, and a second pin 48. The first pin 46 is capable of passing through the opening 34 of the circuit board 32 and inserting into the first hole 42 of the other shield. The second pin 48 is capable of inserting into the second hole 44 of the other shield when the first shield 38 and the second shield 40 are closed. In addition, two grooves 50 are formed on the first shield 38 and the second shield 40, one grove on each shield. Cushions 52 are installed inside the groove 50 of the first shield 38 and the groove 50 of the second shield 40. The two cushions 52 can be attached to the groove 50 of the first shield 38 and the groove 50 of the second shield 40. Each cushion 52 can be a deformable component which can be made of rubber or foam (i.e., PORON, EPDM) so as to avoid crushing the connector 36 when the cushions 52 contact with the connector 36 with the combination of the first shield 38 and the second shield 40.
Please refer to FIG. 3, FIG. 4, and FIG. 5. FIG. 4 is a diagram of the interface card 30 when the first shield 38 and the second shield 40 are not closed according to the first embodiment of the present invention. FIG. 5 is a diagram of the interface card 30 when the first shield 38 and the second shield 40 are closed respectively the first embodiment of the present invention. When the interface card 30 is not utilized, the second pin 48 of the first shield 38 can be inserted into the second hole 44 of the second shield 40 and the second pin 48 of the second shield 40 can be inserted into the second hole 44 of the first shield 38 so as to combine the first shield 38 with the second shield 40.

The connector 36 contacts with the cushions and will not be crushed.
Please refer to FIG. 6. FIG. 6 is a diagram of the interface card 30 inserted into a motherboard 54 according to the first embodiment of the present invention. The motherboard 54 includes a plurality of slots 56 which can conform to PCI-E, PCI, and so on. The interface card 30 can be inserted into one of the slots 56. The interface of the connector 36 of the interface card 30 needs to match the interface of the slot 56. When the interface card 30 is inserted into the slot 56, the first shield 38 and the second shield 40 are opened so as to cover the joint of the connector 36 of the interface card 30 and the slot 56. This can prevent dust from collecting on the joint of the connector 36 and the slot 56 keeping the electrical connection between the interface card 30 and the motherboard 54 clean.
Please refer to FIG. 7. FIG. 7 is an exploded diagram of an interface card 60 according to a second embodiment of the present invention. The difference between the interface card 30 of the first embodiment and the interface card 60 of the second embodiment is that the interface card 60 utilizes magnetic spacers as a mechanism for combining the two shields instead of utilizing pins and holes as a mechanism for combining the two shields of the interface card 30. The interface card 60 also includes the circuit board 32 and the connector 36 installed on a side of the circuit board 32. The interface card 60 further includes a covering means 62. The covering means 62 includes a first shield 64 installed on a side of the circuit board 32 and a second shield 66 installed on the other side of the circuit board 32 for combining with the first shield 64 so as to cover the connector 36. Two magnetic spacers 68 are installed on the bottom of the first shield 64 and on the bottom of the second shield 66 respectively so as to provide magnetic force for combining the second shield 66 with the first shield 64 tightly. In addition, the first shield 64 includes the first holes 42 and the first pins 46 on the top of the first shield 64, and the second shield 66 includes the first holes 42 and the first pins 46 on the top of the second shield 66. The first pins 46 are capable of passing through the openings 34 of the circuit board 32 and inserting into the first holes 42 of the other shield. The grooves 50 are formed on the first shield 64 and the second shield 66. The cushions 52 are installed inside the groove 50 of the first shield 64 and the groove 50 of the second shield 66. The cushions 52 can be attached to the groove 50 of the first shield 38 and the groove 50 of the second shield 40. Each cushion 52 can be a deformable component which can be made of rubber or foam (i.e., PORON, EPDM) so as to avoid crushing the connector 36 when the cushions 52 contact with the connector 36 with the combination of the first shield 64 and the second shield 66.
Please refer to FIG. 7, FIG. 8, and FIG. 9. FIG. 8 is a diagram of the interface card 60 when the first shield 64 and the second shield 66 are not closed according to the second embodiment of the present invention. FIG. 9 is a diagram of the interface card 60 when the first shield 64 and the second shield 66 are closed according to the second embodiment of the present invention. When the interface card 60 is not utilized, the magnetic spacer 68 on the first shield 64 and the magnetic spacer 68 on the second shield 66 attract each other so as to combine the first shield 64 with the second shield 66. The first shield 64 and the second shield 66 can cover the connector 36 of the interface card 60 instead of leaving the connector 36 exposed to air so as to prevent dust from collecting on the connector 36 or to prevent the connector 36 from being oxidized.
Please refer to FIG. 10. FIG. 10 is a diagram of the interface card 60 inserted into the motherboard 54 of the second embodiment according to the present invention. The motherboard 54 includes the plurality of slots 56. When the interface card 60 is inserted into the slot 56, the first shield 64 and the second shield 66 are open so as to cover the joint of the connector 36 of the interface card 60 and the slot 56. This can prevent dust from gathering on the joint of the connector 36 and the slot 56 keeping the electrical connection between the interface card 60 and the motherboard 54 clean.
In contrast with the conventional interface card, the interface card according to the present invention utilizes two shields to cover the connector. When the interface card is not utilized, the connector can be protected by the shields. When the interface card is inserted into a slot of a motherboard, the shields can open so as to cover the joint of the connector of the interface card and the slot. This can prevent dust from gathering on the joint of the connector and the slot thereby keeping the electrical connection between the interface card and the motherboard clean.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
