The invention discloses an optical cage sub-assembly, an optical module connector and a manufacturing method of the optical cage sub-assembly, and belongs to the technical field of optical module heat dissipation. The light cage assembly comprises a box-shaped shell, a radiator and a cover-shaped buckle. The box-shaped shell is provided with a slot, and a first shell wall of the box-shaped shell is provided with an opening at a position close to a slot opening of the slot; the radiator is located at the opening and can be attached to the electric connector inserted into the slot. The cover-shaped buckle is fixed to the shell wall of the box-shaped shell and provided with a memory alloy part, the memory alloy part is located on the surface, away from the opening, of the radiator, and the memory alloy part is configured to enable the radiator to be tightly attached to the electric connector located in the inserting groove when the temperature is higher than a temperature threshold value and enable the radiator to be tightly attached to the electric connector located in the inserting groove when the temperature is lower than the temperature threshold value. And a gap is formed between the radiator and the electric connector in the slot. With the adoption of the optical module, the optical module can be easily plugged in and pulled out of the slot, the heat transfer speed between the radiator and the optical module can be increased, and the radiating effect of the optical module is enhanced.
Description
technical field [0001] The present application relates to the technical field of heat dissipation of optical modules, and in particular, to an optical cage assembly, an optical module connector, and a manufacturing method of the optical cage assembly. Background technique [0002] The optical cage is the shell of the interface part of the optical communication equipment, and has slots, and the slots are used for inserting the electrical connectors of the optical modules, so as to realize the connection between the optical modules and the connectors in the optical cage. [0003] Considering the plugging and unplugging of the electrical connector of the optical module in the slot, there is a certain gap between the slot and the electrical connector of the optical module inserted into the slot, so as to facilitate plugging and unplugging. [0004] In order to dissipate heat from the optical module, a heat sink is installed on the outer surface of the slot wall of the slot to ab...
