Description

Connector components

The present invention relates to a connector assembly, and in particular to a connector assembly with a movable heat sink.

Chinese Invention Announcement No. CN109283635B (corresponding to U.S. Invention Announcement No. US10295767B2) discloses a double cam structure, including a cam structure and a front-end cam structure. When the transceiver is fully inserted into the top bracket, this double cam structure can facilitate the connection between the transceiver and the radiator. contact between. The base of the radiator includes a forward slot and a rear angled slot that guide movement of the radiator relative to the cam structure. In the initial position before the cam structure is pushed, the cam structure is in contact with the slot so that the heat sink is in a higher position relative to the transceiver. After the transceiver is pushed to the end of travel of the top bracket, the rear connector interface engages the connector electronics, the cam structure moves relative to the slot, and the front cam structure pushes the heat sink further down, and the cam structure is pushed through the front slot. The slot is angled so the heatsink is pushed down to contact the transceiver by the downward pressure provided by the clamp. When the transceiver is fully inserted into the top bracket, the spring is compressed between the contact portion of the cam structure and the stop. When the transceiver is removed from the top bracket, the transceiver uses the thrust generated by the spring to push the cam structure back to the original position of the front slot.

However, the cam structure coupled with the front cam structure to raise the heat sink to create a gap between the heat sink and the transceiver will prevent the transceiver from contacting the thermal interface material when partially inserted, and because it is required The two cam structures work together to raise and lower the radiator, which makes the overall structure relatively complex. Furthermore, the cam structure and the spring occupy part of the internal space of the top bracket. When the internal space of the top bracket is insufficient in design, the structure in the prior art will not be applicable.

U.S. Invention Notice No. US10222844B1 discloses that a sliding ramp is provided with an inclined slope on the top side of the cage. The radiator moves along the inclined sliding ramp through a guide pin, so that the radiator is pressed downward against the replaceable electronic module. Thermal contact is established on and compresses the leaf spring set on the back of the cage. When the leaf spring is released, the radiator is pushed toward the front of the sliding ramp, thereby pushing the replaceable electronic module outward from the cage.

However, since the radiator disclosed in this prior art moves obliquely along an inclined sliding type ramp, it is necessary to reduce the size of the protrusion on the bottom surface of the radiator to be smaller than the window size of the cage top wall to avoid interference. Furthermore, even though the thermal interface material used on the convex portion of the bottom surface of the heat sink can be compressed, the thickness of the thermal interface material is usually thin, so the elasticity produced by the compression of the thermal interface material is usually very small, or even It can be said that the thermal interface material is inelastic, so that the heat sink will directly and rigidly contact the surface of the replacement electronic module according to the inclination angle and length of the sliding ramp. If the amount of interference is too much, it may hinder the insertion of the replacement electronic module, and even cause the thermal interface material to be worn or damaged. If the amount of interference is too little, it may affect the contact area and heat dissipation efficiency of the heat dissipation interface.

Therefore, one object of the present invention is to provide a connector assembly that can improve at least one problem in the prior art.

Therefore, in some embodiments, the connector assembly of the present invention includes a guide shield, a heat sink, a buckle, and a heat sink support structure.

When the pluggable module is inserted into the plug channel of the guide shield, the pluggable module The drafting group pushes the trigger of the rotating rod to move laterally outward in the direction away from the plug channel, the rear end of the rotating rod rotates laterally outward, and the plug latch moves laterally outward. Leaving the bottom of the radiator, and lowering the radiator to the lower working position through the downward elastic force of the buckle, the thermal coupling part enters the heat sink through the window of the top wall. In the insertion channel to contact the upper surface of the pluggable module, the buckle exerts an elastic working load on the heat sink downward to provide the heat sink with the pluggable module. The working contact pressure between the surfaces, the rotating rod further twists and compresses the spring; when the pluggable module exits from the plug channel, after the pluggable module leaves the trigger , the restoring force of the spring causes the rear end of the rotating rod to rotate laterally and inwardly, the trigger passes through the guide shield and enters the plug-in channel, and the plug bolt is inserted laterally and inwardly. lower the bottom of the radiator and raise the radiator to the upper non-working position.
