## Abstract

A release mechanism for releasing a transceiver module from a cage includes a fixed component, a locking component, and a pull component, where the locking component is used for locking the transceiver module in the cage and pivotally connected to the transceiver module. The user pulls the pull component to make the locking component to rotate to unlock and then draw out the transceiver module. The locking component further includes a spring part against the fixed component to resist the rotation and assist the locking component back to the original position. According to the fewer components and the easy assembly of the release mechanism, the total assembly cost of the transceiver module can be reduced significantly.

## Claims

### Claim 1

A release mechanism for releasing a transceiver module from a cage, the release mechanism comprising:
a fixed component, fixed on the transceiver module;
a locking component, having a connecting part, a hook opposite to the connecting part, and a spring part configured between the connecting part and the hook, the connecting part being pivotally connected to the transceiver module to enable the locking component to rotate relatively to the connecting part, the spring part being against the fixed component to resist the rotation of the locking component, the hook being for locking the transceiver module in the cage; and
a pull component, connected to the locking component, for pulling the locking component to rotate to release the hook and the transceiver module from the cage.

### Claim 2 (depends on 1)

The release mechanism of claim 1, further comprising a connecting pin for connecting the locking component and the pull component.

### Claim 3 (depends on 2)

The release mechanism of claim 2, wherein the pull component comprises a sheath for the connecting pin being plugged therein, and the locking component comprises a fastening part for fastening the connecting pin.

### Claim 4 (depends on 1)

The release mechanism of claim 1, wherein the spring part is a leaf spring extending from the main body of the locking component.

### Claim 5 (depends on 1)

The release mechanism of claim 1, wherein the locking component has an opening for accepting a pin of the transceiver module to form the pivotal connection between the locking component and the transceiver module.

### Claim 6

A transceiver module, comprising:
a case, for accepting a print circuit board and being plugged into a cage;
a fixed component, fixed on the case;
a locking component, having a connecting part, a hook opposite to the connecting part, and a spring part configured between the connecting part and the hook, the connecting part being pivotally connected to the case to enable the locking component to rotate relatively to the connecting part, the spring part being against the fixed component to resist the rotation of the locking component, the hook being for locking the case in the cage; and
a pull component, connected to the locking component, for pulling the locking component to rotate to release the hook and the case from the cage.

### Claim 7 (depends on 6)

The transceiver module of claim 6, further comprising a connecting pin for connecting the locking component and the pull component.

### Claim 8 (depends on 7)

The transceiver module of claim 7, wherein the pull component comprises a sheath for the connecting pin being plugged therein, and the locking component comprises a fastening part for fastening the connecting pin.

### Claim 9 (depends on 6)

The transceiver module of claim 6, wherein the spring part is a leaf spring extending from the main body of the locking component.

### Claim 10 (depends on 6)

The transceiver module of claim 6, wherein the locking component has an opening and the case has a pin, the opening accepts the pin to form the pivotal connection between the locking component and the case.
