Automatic ejection mechanism of connecting device

1. An automatic ejection mechanism of a connecting device, the automatic ejection mechanism comprising:

an outer shell defining an accommodating space and comprising a rear cover covering a rear end of the accommodating space;

a connector slidably received within the accommodating space;

a fastening assembly located between the connector and the rear cover; and

a resilient member located between the connector and the rear cover;

wherein the resilient member drives the connector to slide toward an opening of a front end of the accommodating space;

wherein the connector is received within the accommodating space by being fastened to the fastening assembly; and

wherein the connector is ejected out of the opening of the front end by releasing the fastening assembly from the connector;

wherein the connector comprises a base and a circuit board; a front end of the base is covered and faces the opening of the front end of the accommodating space; the circuit board is located within the base and faces the fastening assembly through an opening of a rear end of the base; the circuit board comprises a connector socket positioned in front of a connector opening defined in a side of the base; the connector opening is exposed outside of the outer shell when the connector is ejected out of the front end of the accommodating space.

2. The automatic ejection mechanism of claim 1 , wherein the outer shell defines a limiting groove in opposite inner walls of the accommodating space; the limiting groove extends to the rear end of the accommodating space and is covered by the front end of the accommodating space so that the connector, when ejected out of the opening of the front end, is not completely ejected out of the accommodating space.

3. The automatic ejection mechanism of claim 1 wherein the base comprises a balancing bar; the balancing bar extends along a bottom periphery of the opening of the rear end of the base; two ends of the balancing bar are pivotably coupled to opposite inner walls of the accommodating space; the balancing bar stabilizes movement of the base within the accommodating space.

4. The automatic ejection mechanism of claim 3 , wherein the fastening assembly comprises a buckle and a pair of hook clasps; the hook clasps are located within the base and extend toward the opening of the rear end of the base; the buckle is located in the opening of the rear end of the base; two ends of the buckle correspond to the pair of hook clasps; the two ends of the buckle clasped to the hook clasps causes the connector to be received within the accommodating space of the outer shell.

5. The automatic ejection mechanism of claim 4 , wherein the buckle comprises a lever; a first end of the lever is fixed to an upper periphery of the buckle; a second end of the lever extends beyond an outer surface of the accommodating space toward an outer surface of the housing; the lever clasps the buckle to the hook clasps.

6. The automatic ejection mechanism of claim 5 , wherein the lever comprises an extension spring between the lever and the outer surface of the accommodating space; a retraction force of the extension spring causes the buckle to be in a clasping position with the hook clasps.

7. The automatic ejection mechanism of claim 5 , wherein the lever comprises a releasing toggle located on the second end of the lever; the releasing toggle releases the buckle from the hook clasps.

8. The automatic ejection mechanism of claim 5 , wherein the outer surface of the housing defines a limiting hole; the lever extends through the limiting hole; the limiting hole limits movement of the lever to cause the buckle to be positioned in the clasping position with the hook clasps.

9. The automatic ejection mechanism of claim 1 , wherein the resilient member is located on the rear cover; the resilient member corresponds to the connector through the fastening assembly; the rear cover covers the rear end of the accommodating space so that the resilient member exerts force on the connector.
