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 connector has a first connection end configured to fit with a peer adapter. The electrical connector has a second connection end configured to fit with the peer adapter. The first connection end and the second connection end have a same opening direction. In addition, the first connection end may slide along a plugging direction of the peer adapter relative to the second connection end. The first connection end is configured to be connected to the peer adapter before the second connection end. The optical connector is connected to the peer adapter before the electrical connector. This ensures that a channel for transmitting an optical signal is communicated before a channel for transmitting an electrical signal is communicated, thereby avoiding fiber burning and improving security and reliability of the opto-electronic adapter during use.

Abstract: A message notification method and an electronic device are provided. When a primary screen is turned off, prompt information of a notification message is displayed on a secondary screen located right above a front-facing camera, so that a user can notice a message notification in time, and user experience is improved. A specific solution is as follows: After the primary screen is turned off, if the electronic device detects a first notification message, the electronic device displays first information on the secondary screen. The first information is used to prompt the user that the first notification message has been received. The electronic device detects a first operation in which the user indicates to turn on the primary screen. The electronic device turns on the primary screen in response to the first operation. The electronic device displays second information on the secondary screen.
