Abstract

An active device module may include an active device, a housing configured to house the active device, a slide release latch mechanically coupled to the housing via a spring having a spring force that biases the slide release latch in a first position relative to the housing, and connectivity flaps mechanically coupled to the slide release latch via activation levers, wherein when the slide release latch is in the first position and a cable is inserted into the active device module, the connectivity flaps apply a compressive force to either side of the cable to mechanically maintain the cable within the active device module. The housing, the slide release latch, the activation levers, and the connectivity flaps may be arranged such that, when an external force is applied to the slide release latch to overcome the spring force of the spring to cause the slide release latch to move from the first position to a second position relative to the housing, the slide release latch exerts mechanical force on the activation levers, which in turn applies a force to the connectivity flaps, pulling at least a portion of each connectivity flap away from another connectivity flap, thereby reducing the compressive force retaining the cable between the connectivity flaps.

First claim

What is claimed is:

1. An active device module, comprising:
an active device;
a housing configured to house the active device;
a slide release latch mechanically coupled to the housing via a spring having a spring force that biases the slide release latch in a first position relative to the housing; and
connectivity flaps mechanically coupled to the slide release latch via activation levers, wherein when the slide release latch is in the first position and a cable is inserted into the active device module, the connectivity flaps apply a compressive force to either side of the cable to mechanically maintain the cable within the active device module;
wherein the housing, the slide release latch, the activation levers, and the connectivity flaps are arranged such that, when an external force is applied to the slide release latch to overcome the spring force of the spring to cause the slide release latch to move from the first position to a second position relative to the housing, the slide release latch exerts mechanical force on the activation levers, which in turn applies a force to the connectivity flaps, pulling at least a portion of each connectivity flap away from another connectivity flap, thereby reducing the compressive force retaining the cable between the connectivity flaps.

2. The active device module of claim 1 , wherein the active device is an optical transceiver.

3. The active device module of claim 1 , further comprising:
a push lever mechanically coupled to the housing via a second spring that biases the push lever in a resting position relative to the housing; and
wherein the housing, the slide release latch, and the push lever are arranged such that, when the external force is applied to the slide release latch to cause the slide release latch to move from the first position to the second position relative to the housing, the slide release latch exerts mechanical force on the push lever, causing motion of the push lever from the resting position to eject the cable from the active device module.

4. A method for fabricating an active device module comprising:
housing an active device within a housing;
mechanically coupling a slide release latch to the housing via a spring having a spring force that biases the slide release latch in a first position relative to the housing;
mechanically coupling connectivity flaps to the slide release latch via activation levers, wherein when the slide release latch is in the first position and a cable is inserted into the active device module, the connectivity flaps apply a compressive force to either side of the cable to mechanically maintain the cable within the active device module; and
arranging the housing, the slide release latch, the activation levers, and the connectivity flaps such that, when an external force is applied to the slide release latch to overcome the spring force of the spring to cause the slide release latch to move from the first position to a second position relative to the housing, the slide release latch exerts mechanical force on the activation levers, which in turn applies a force to the connectivity flaps, pulling at least a portion of each connectivity flap away from another connectivity flap, thereby reducing the compressive force retaining the cable between the connectivity flaps.

5. The method of claim 4 , wherein the active device is an optical transceiver.

6. The method of claim 4 , further comprising:
mechanically coupling a push lever to the housing via a second spring that biases the push lever in a resting position relative to the housing; and
arranging the housing, the slide release latch, and the push lever such that, when the external force is applied to the slide release latch to cause the slide release latch to move from the first position to the second position relative to the housing, the slide release latch exerts mechanical force on the push lever, causing motion of the push lever from the resting position to eject the cable from the active device module.

7. An information handling system, comprising:
a processor; and
an active device module communicatively coupled to the processor and comprising:
an active device;
a housing configured to house the active device;
a slide release latch mechanically coupled to the housing via a spring having a spring force that biases the slide release latch in a first position relative to the housing; and
connectivity flaps mechanically coupled to the slide release latch via activation levers, wherein when the slide release latch is in the first position and a cable is inserted into the active device module, the connectivity flaps apply a compressive force to either side of the cable to mechanically maintain the cable within the active device module;
wherein the housing, the slide release latch, the activation levers, and the connectivity flaps are arranged such that, when an external force is applied to the slide release latch to overcome the spring force of the spring to cause the slide release latch to move from the first position to a second position relative to the housing, the slide release latch exerts mechanical force on the activation levers, which in turn applies a force to the connectivity flaps, pulling at least a portion of each connectivity flap away from another connectivity flap, thereby reducing the compressive force retaining the cable between the connectivity flaps.

8. The information handling system of claim 7 , wherein the active device is an optical transceiver.

9. The information handling system of claim 7 , the active device module further comprising:
a push lever mechanically coupled to the housing via a second spring that biases the push lever in a resting position relative to the housing; and
wherein the housing, the slide release latch, and the push lever are arranged such that, when the external force is applied to the slide release latch to cause the slide release latch to move from the first position to the second position relative to the housing, the slide release latch exerts mechanical force on the push lever, causing motion of the push lever from the resting position to eject the cable from the active device module.
