Abstract: A heat dissipation assembly includes: a heat spreader, configured to be in contact with an element; a frame body, configured to limit a position of the heat spreader, where the frame body surrounds a side wall of the heat spreader; and an elastic structure, fixedly connected to the frame body. In this application, the heat spreader is disposed, so that heat generated by the element can be evenly conducted; furthermore, the elastic structure fixedly connected to the frame body is disposed, so that the element, the heat spreader, and the frame body are reliably fastened in a thickness direction, to ensure that heat generated by the element can be smoothly conducted. In addition, because a requirement on adhesion strength of a heat conducting material is reduced, a heat conducting material with better heat dissipation performance can be selected, thereby further improving and heat dissipation efficiency of a chip is further improved.

Abstract: An optical port shielding and fastening apparatus is configured to be installed in the optical module. The optical module includes a housing assembly and an optical component located in the housing assembly. The optical port shielding and fastening apparatus includes a fastener and an electromagnetic wave absorbing piece. The fastener is fastened in the housing assembly. The electromagnetic wave absorbing piece is fastened on a side that is of the fastener and that faces an outside of the housing assembly. A first mounting hole and a second mounting hole are correspondingly provided on the fastener and the electromagnetic wave absorbing piece. The optical component passes through the first mounting hole and the second mounting hole in sequence. This application provides an optical port shielding and fastening apparatus, an optical module, and a communications device, to resolve poor optical port shielding performance of an optical module in the related technology.

Abstract: An optical module unlocking apparatus includes: a base, a sliding member, a driving piece, and an elastic piece. The sliding member is slidably disposed on the base along an insertion direction. The driving piece is rotatably connected to the base, the other end of the sliding member is connected to the driving piece, and the driving piece can rotate from a locked state to an unlocked state relative to the base under an action of external force, and drive the sliding member to move relative to the base along the insertion direction. A second connecting part is disposed on the driving piece. Because the driving piece is located outside a cage, space for disposing the elastic piece on the driving piece is sufficient, and the driving piece does not need to fit a spring plate. This simplifies a structure of the optical module and improves processing efficiency.

Abstract: An optical module unlocking apparatus includes a housing, including a base and a mounting portion connected to one end of the base. The base has an accommodation area for installing a circuit board and an electrical component. The apparatus also includes an unlocking component, including an unlocking arm movably connected to the housing. The unlocking arm has an abutment portion for abutting against an elastomer of a cage, and the unlocking component is configured to push the unlocking arm outward relative to the housing in an insertion direction under an action of external force to separate the abutment portion from the elastomer. The apparatus further includes an elastic component on an outer side surface of the mounting portion and outside the accommodation area. A first end of the elastic component is connected to the mounting portion and a second end of the elastic component is connected to the mounting portion.
