Abstract

A security device for a HDMI connector having a HDMI connector head provided on an electronic device having a HDMI socket. The security device includes a locking device including a locking head and a plurality of locker arms extended from two sides of the locking head respectively to define a locker channel for detachably receiving the HDMI connector head. Each of the locker arms has a plurality of engaging teeth formed therealong, wherein the locking device is arranged to operate between a locking mode and a releasing mode, wherein in the locking mode, the locker arms are inwardly pressed to bias against the HDMI connector head when the HDMI connector is plugged into the HDMI socket, wherein in the releasing mode, the locker arms are relieved from the pressing force so as to allow the HDMI connector head to be freely detached from the HDMI socket.

Claims

1. A security device for a HDMI cable connector having a HDMI connector head provided on an electronic device having a HDMI socket, wherein said security device comprises:

a locking device which is detachably mounted on said electronic device, and comprises;

a locking head;

a plurality of locker arms extended from two sides of said locking head respectively to define a locker channel for detachably receiving said HDMI connector head, wherein each of said locker arms has a plurality of engaging teeth formed therealong, wherein said locking device is arranged to operate between a locking mode and a releasing mode, wherein in said locking mode, said locker arms are inwardly pressed to bias against said HDMI connector head when said HDMI connector is plugged into said HDMI socket, wherein in said releasing mode, said locker arms are relieved from said pressing force so as to allow said HDMI connector head to be freely detached from said HDMI socket;

a security housing which is provided on said electronic device at a position corresponding to that of said HDMI socket, wherein said security housing comprises a plurality of sidewalls rearwardly extended from said rear side of said electronic device to define a receiving cavity between said sidewalls, and an access opening communicating said receiving cavity with an exterior of said security device.

2. The security device, as recited in claim 1, wherein each of said locker arms further has a biasing ridge protruded from an inner side of said locker arm and is extended along a longitudinal direction thereof, wherein each of said biasing ridges has a triangular cross section having a width gradually decreasing from said locker panel to a free end of said locker arm.

3. The security device, as recited in claim 2, wherein each of said biasing ridges defines an engaging platform wherein said engaging teeth are provided on said engaging platform for engaging with said HDMI connector head, wherein said biasing ridges are arranged to exert a biasing force toward said HDMI connector head when said locker arms are inserted into said locker slots respectively.

4. The security device, as recited in claim 1, wherein said security housing further has a plurality of locker slots spacedly formed at one of said sidewalls of said security housing, wherein each of said locker arms is arranged to insert into said receiving cavity through said corresponding locker slot.

5. The security device, as recited in claim 4, wherein each of said locker arms has a latch protruded from an outer side of said corresponding locker arm for engaging with a corresponding outer side edge of said corresponding locker slot, wherein each of said locker arms has a predetermined elasticity such that when said locker arms are inserted into said locker slots, said latches are arranged to elastically bias against an outer side of said sidewall.

6. The security device, as recited in claim 4, wherein said locking head comprises a handle and a locker panel extended from said handle, and is aligned with said sidewall having said locker slots formed thereon, wherein said locker panel is arranged to bias against said corresponding sidewall when said locker arms are inserted into said locker slots respectively so as to stop a further inward movement of said locking device.

7. The security device, as recited in claim 6, wherein each of said locker arms further has a biasing ridge protruded from an inner side of said locker arm and is extended along a longitudinal direction thereof, wherein each of said biasing ridges has a triangular cross section having a width gradually decreasing from said locker panel to a free end of said locker arm.

8. The security device, as recited in claim 7, wherein each of said biasing ridges defines an engaging platform wherein said engaging teeth are provided on said engaging platform for engaging with said HDMI connector head, wherein said biasing ridges are arranged to exert a biasing force toward said HDMI connector head when said locker arms are inserted into said locker slots respectively.

9. The security device, as recited in claim 6, wherein each of said locker arms has a latch protruded from an outer side of said corresponding locker arm for engaging with a corresponding outer side edge of said corresponding locker slot, wherein each of said locker arms has a predetermined elasticity such that when said locker arms are inserted into said locker slots, said latches are arranged to elastically bias against an outer side of said sidewall.

10. The security device, as recited in claim 9, wherein each of said locker arms further has an auxiliary latch outwardly extended from said free end thereof, and is arranged to bias against said inner side of said sidewall having said locker slots when said locking device is pulled to detach from said security housing.

11. The security device, as recited in claim 9, wherein each of said locker arms further has a biasing ridge protruded from an inner side of said locker arm and is extended along a longitudinal direction thereof, wherein each of said biasing ridges has a triangular cross section having a width gradually decreasing from said locker panel to a free end of said locker arm.

12. The security device, as recited in claim 11, wherein each of said locker arms further has an auxiliary latch outwardly extended from said free end thereof, and is arranged to bias against said inner side of said sidewall having said locker slots when said locking device is pulled to detach from said security housing.

13. The security device, as recited in claim 11, wherein said locker arms are integrally extended from two sides of said locker panel respectively for biasing against said HDMI connector head.

14. The security device, as recited in claim 11, wherein each of said biasing ridges defines an engaging platform wherein said engaging teeth are provided on said engaging platform for engaging with said HDMI connector head, wherein said biasing ridges are arranged to exert a biasing force toward said HDMI connector head when said locker arms are inserted into said locker slots respectively.

15. The security device, as recited in claim 14, wherein said locker arms are integrally extended from two sides of said locker panel respectively for biasing against said HDMI connector head.

16. The security device, as recited in claim 14, wherein each of said locker arms further has an auxiliary latch outwardly extended from said free end thereof, and is arranged to bias against said inner side of said sidewall having said locker slots when said locking device is pulled to detach from said security housing.

17. The security device, as recited in claim 16, wherein a length of each of said locker slots is slightly longer than a width of said corresponding locker arm so as to allow easy insertion thereof.

18. The security device, as recited in claim 16, wherein said locker arms are integrally extended from two sides of said locker panel respectively for biasing against said HDMI connector head.

19. The security device, as recited in claim 18, wherein a length of each of said locker slots is slightly longer than a width of said corresponding locker arm so as to allow easy insertion thereof.
