Abstract

A fuse structure for a plug device is disposed in a body of the plug device and configured to be electrically connected to a plug circuit of the plug device. The plug device includes at least one casing for exposing a pin, in which an assembly chamber for a fuse and a cover are disposed below the casing. A horizontal slot for the fuse is disposed in the fuse assembly chamber, and the cover is configured cover the assembly chamber for the fuse. A pivot shaft of the cover is disposed adjacent to an articulating shaft of the casing, and the cover is prevented from being opened by the casing when the casing is unfolded.

Claims

1. A fuse structure for a plug device, disposed in a body of the plug device and configured to be electrically connected to a plug circuit of the plug device, the plug device comprising at least one casing for exposing a pin, wherein an assembly chamber for a fuse and a cover are disposed below the casing, a horizontal slot for the fuse is disposed in the fuse assembly chamber, and the cover is configured to cover the assembly chamber for the fuse;

a pivot shaft of the cover is disposed adjacent to an articulating shaft of the casing, and the cover is prevented from being opened by the casing when the casing is unfolded.

2. The fuse structure according to claim 1, wherein the plug device further comprises a pin module having at least one fixed pin and disposed in an inserting direction;

the articulating shaft of the casing is configured to be a first articulating shaft disposed in a bottom of the pin module, and the casing is configured to have two casings, including a first casing and a second casing, disposed to two sides of the pin module and rotatable about the first articulating shaft;

a slot is disposed in a middle portion of the first casing, a movable pin corresponding to the fixed pin is disposed to the second casing, and the movable pin is configured such that the movable pin is located in the slot when the two casings are folded, and the movable pin is turned out of the slot when the two casings are unfolded, to form a plug cooperating with the fixed pin.

3. The fuse structure according to claim 2, wherein a rotatable second articulating shaft is disposed in a bottom of the movable pin, a third articulating shaft is disposed at a predetermined distance from the second articulating shaft, and a pull tab articulated with the third articulating shaft is disposed at an inner sidewall of the second casing;

the movable pin is L-shaped, and the second articulating shaft and the third articulating shaft are located in an end of a bottom of the L-shaped movable pin.

4. The fuse structure according to claim 3, wherein the pull tab is connected to the inner sidewall of the second casing through a fourth articulating shaft.

5. The fuse structure according to claim 3, wherein two fixed pins are provided, and the fixed pins and the movable pin are configured as BS pins of Hong Kong standard.

6. The fuse structure according to claim 3, wherein an elastic element for unfolding the first casing and the second casing is disposed around the first articulating shaft between the first casing and the second casing.

7. The fuse structure according to claim 6, wherein the elastic element is configured as a coil spring, and two legs of the elastic element are fixed on the first casing and the second casing, respectively.

8. The fuse structure according to claim 6, wherein a button is disposed on a sidewall of the first casing, and configured to release a snap-fit structure for folding the first casing and the second casing when pressed;

the snap-fit structure includes a resilient snap protrusion at a corresponding position of the second casing, and a press portion on a bottom surface of the button and configured to be fitted with the resilient snap protrusion.

9. The fuse structure according to claim 8, wherein the plug device is further provided with a power storage unit.

10. The fuse structure according to claim 8, wherein the plug device is further provided with at least one USB power output.
