Abstract

A protection device for protecting a power cable connector includes one sensor, a separation mechanism and a processing unit. The sensor is for sensing a relative distance and a moving speed of an external object. The separation mechanism is connected to the power cable connector in a separable manner. The processing unit is electrically connected to the sensor for controlling the separation mechanism to separate from the power cable connector as the sensor senses that the relative distance is less than a separation distance and the moving speed is not zero.

First claim

What is claimed is:

1. A protection device for protecting a power cable connector, the protection device comprising:
a sensor for sensing a relative distance and a moving speed of an external object;
a separation mechanism detachably connected to the power cable connector, the separation mechanism comprising:
at least one connecting component for detachably engaging with the power cable connector; and
a pressing component for providing a force to the power cable connector; and

a processing unit electrically connected to the sensor for controlling the separation mechanism to separate from the power cable connector as the sensor senses that the relative distance is smaller than a separation distance and the moving speed is not equal to zero.

2. The protection device of claim 1 , wherein the power cable connector comprises a magnetic component, the separation mechanism is an electromagnetic mechanism for generating a magnetic pole having the same magnetic property as the magnetic component of the power cable connector, so as to generate a repulsive force to separate the power cable connector from the separation mechanism when the electromagnetic mechanism generates the magnetic pole.

3. The protection device of claim 1 , wherein
the at least one connecting component comprises at least one engaging component for detachably engaging with the power cable connector; and
the pressing component comprises an elastic component for providing a force to the power cable connector when the processing unit drives the at least one engaging component to detach from the power cable connector, so as to separate the power cable connector from the separation mechanism.

4. The protection device of claim 1 , wherein the separation mechanism comprises:
an ejecting bar for moving the power cable connector; and
a pushing component connected to the ejecting bar, the processing unit driving the pushing component to push the ejecting bar so that the ejecting bar moves the power cable connector to be out of the separation mechanism.

5. The protection device of claim 1 , further comprising:
an alarm unit electrically connected to the processing unit, the processing unit further controlling the alarm unit to generate an alarm prompt when the relative distance is smaller than an alarm distance and greater than the separation distance.

6. The protection device of claim 5 , wherein the alarm unit is an audio component, a light emitting component or a vibrating component.

7. The protection device of claim 1 , wherein the sensor comprises two sensing units respectively for sensing two relative directions.

8. A power supply comprising:
a power cable connector;
a power cable connected to the power cable connector; and
a main body, the main body comprising:
a supply connector detachably connected to the power cable connector;
a separation mechanism, the separation mechanism comprising:
at least one connecting component for detachably engaging with the power cable connector; and
a pressing component for providing a force to the power cable connector;

a sensor for sensing a relative distance and a moving speed of an external object; and
a processing unit electrically connected to the sensor for controlling the separation mechanism to separate the power cable connector from the supply connector as the sensor senses that the relative distance is smaller than a separation distance and the moving speed is not equal to zero.

9. The power supply of claim 8 , wherein the power cable connector comprises a magnetic component, the separation mechanism is an electromagnetic mechanism for generating a magnetic pole having the same magnetic property as the magnetic component of the power cable connector, so as to generate a repulsive force to separate the power cable connector from the separation mechanism when the electromagnetic mechanism generates the magnetic pole.

the at least one connecting component comprises at least one engaging component for detachably engaging with the power cable connector; and
the pressing component comprises an elastic component for providing a recovering force to the power cable connector when the processing unit drives the at least one engaging component to detach from the power cable connector, so as to separate the power cable connector from the separation mechanism.

11. The power supply of claim 8 , wherein the separation mechanism comprises:
an ejecting bar for moving the power cable connector; and
a pushing component connected to the ejecting bar, the processing unit driving the pushing component to push the ejecting bar so that the ejecting bar moves the power cable connector to be out of the separation mechanism.

12. The power supply of claim 8 , further comprising:
an alarm unit electrically connected to the processing unit, the processing unit further controlling the alarm unit to generate an alarm prompt when the relative distance is smaller than an alarm distance and greater than the separation distance.

13. An electronic system comprising:
