Abstract

A security block for securing I/O ports of an electronic instrument physically prevents any breach of data through a protected I/O port, such as a USB port, by securing cables that may be plugged into the port by means of a locked cover. The cables are prevented from being removed and USB memory devices are prevented from being connected in their place. In a second aspect, a portion of the security block covers unused I/O ports thereby preventing USB memory devices and other devices from being connected to unoccupied I/O ports. The locking mechanism can be either a padlock, or a locking screw, or the like.

Claims

1. A securing mechanism for limiting access to at least a first I/O port of an electronic instrument, comprising:

a primary housing mounted on said electronic instrument adjacent to said I/O port, said primary housing enclosing said I/O port on three sides and being open on a fourth side;

said primary housing having a cover including an aperture for receiving a an I/O connector to be connected to said I/O port;

a secondary housing mechanically coupling with said said primary housing in an engaged position to enclose the open fourth side;

said secondary housing having a cover cooperating with said cover of said primary housing to reduce said aperture to a size smaller than said I/O connector said reduced size of said aperture allowing passage of a cable of said I/O connector through said coupled primary and secondary housings when said I/O connector is connected to one of said I/O ports when said secondary housing is in said engaged position;

said primary housing and said secondary housing cooperating when said secondary housing is in said engaged position to prevent removal of said I/O connector from said I/O port;

and

a locking mechanism for locking said secondary housing in said engaged position.

2. The securing mechanism of claim 1, wherein said secondary housing slides within said primary housing.

3. The securing mechanism of claim 2, wherein

a portion of said primary housing has a second aperture, a portion of said secondary housing has a third aperture;

and said second and third apertures are axially aligned when said secondary housing is in said engaged position;

said second and third apertures receiving a portion of said locking mechanism when said secondary housing is in said engaged position.

4. The securing mechanism of claim 3, wherein

said locking mechanism is a padlock.

5. The securing mechanism of claim 3, wherein

said locking mechanism is a locking screw.

6. A securing mechanism for limiting access to a plurality of I/O ports of an electronic instrument, comprising:

a primary housing mounted on said electronic instrument adjacent to said plurality of I/O ports, said primary housing having three sides for enclosing said plurality of I/O ports, and being open on a fourth side;

said primary housing having a cover including an aperture for receiving an I/O connector to be connected to one of said I/O ports;

a secondary housing adapted to mechanically coupling to said primary housing in an engaged position to enclose said open fourth side;

said secondary housing having a cover cooperating with said cover of said primary housing to reduce said aperture to a size smaller than said I/O connector said reduced size of said aperture allowing passage of a cable of said I/O connector through said coupled primary and secondary housings when said I/O connector is connected to one of said I/O ports, when said secondary housing is in said engaged position;

said primary housing and said secondary housing cooperating when said secondary housing is in said engaged position to prevent removal of said I/O connector from an occupied one of said I/O ports, and to prevent connection of another I/O connector to an unoccupied one of said I/O ports; and

a locking mechanism for locking said secondary housing in said engaged position.

7. The securing mechanism of claim 6, wherein said secondary housing slides within said primary housing.

8. The securing mechanism of claim 7, wherein

a portion of said primary housing has a second aperture, a portion of said second housing has a third aperture;

and said second and third apertures are axially aligned when said secondary housing is in said engaged position;

said second and third apertures receiving a portion of said locking mechanism when said secondary housing is in said engaged position.

9. The securing mechanism of claim 8, wherein

said locking mechanism is a padlock.

10. The securing mechanism of claim 8, wherein

said locking mechanism is a locking screw.

11. A securing mechanism for limiting access to a plurality of I/O ports of an electronic instrument, comprising:

a first housing portion attached to a wall of said electronic instrument adjacent to said plurality of I/O ports, said first housing portion having a least one side;

a second housing portion mechanically coupling with said first housing in an engaged position to form an enclosure surrounding said plurality of I/O ports of said electronic instrument;

said enclosure including an aperture allowing passage of a cable of a connector to be connected to one of said I/O ports;

said first housing portion and said second housing portion cooperating when in said engaged position to prevent a connection of a connector to an unoccupied one of said I/O ports;

said first housing portion and said second housing portion cooperating when in said engaged position to prevent removal of a connector from an occupied one of said I/O ports; and

a locking mechanism for locking said first and second housing portions in said engaged position.

12. The securing mechanism of claim 11, wherein

said first housing portion has a second aperture, said second housing portion has a third aperture;

and said second and third apertures are axially aligned when said first and second housing portions are in said engaged position;

said second and third apertures receiving a portion of said locking mechanism when said first and second housing portions are in said engaged position.

13. The securing mechanism of claim 12, wherein

said locking mechanism is a padlock.

14. The securing mechanism of claim 13, wherein

said locking mechanism is a locking screw.

15. An electronic instrument, comprising:

an enclosure, said enclosure of said electronic instrument having a wall, said wall providing access to a plurality of I/O ports of said electronic instrument;

a security device having a first part and a second part;

said first part being attached to said wall of said electronic instrument adjacent to said plurality of I/O ports;

said first part bounding said plurality of I/O ports on three sides, and being open on a fourth side;

said first part having a partial cover forming an opening extending toward an edge of said partial cover from said fourth side;

said second part sliding within said first part to bound said I/O ports on said fourth side;

said second part having a cover portion cooperating with said partial cover of said first part to form an aperture, said aperture reducing in size as said second part moves to an engaged portion within said first part;

when said second part is in said engaged position, said size of said aperture allows outward passage of a cable of said connector connected to one of said I/O ports, does not allow outward passage of said connector through said aperture, and prevents coupling of a second connector to an unoccupied I/O connector by not allowing inward passage of said second connector through said aperture; and

a locking mechanism for locking said second part in said engaged position.

16. The electronic instrument of claim 16, wherein

an area of said first part has a second aperture, an area of said second part has a third aperture;

said second and third apertures being axially aligned when said second portion is in said engaged position;

said alignment of said second and third apertures allowing installation of a portion of said locking mechanism through said second and third apertures.

17. The electronic instrument of claim 17, wherein

said locking mechanism is a padlock.

18. The electronic instrument of claim 17, wherein

said locking mechanism is a locking screw.
