This utility model discloses a keyboard protective cover device, comprising: a first plate; a second plate flexibly connected to one side of the first plate; a keyboard module disposed on the first plate, and a positioning groove and a receiving cavity disposed on one side of the first plate located from the keyboard module; an attachment portion flexibly disposed on the side of the second plate away from the first plate, the attachment portion being connected to an electronic device; in the stored state, the second plate is disposed in the receiving cavity, and the electronic device is brought into contact with the first plate and closed through the attachment portion, thus protecting the screen and keyboard module of the electronic device; in the supported state, multiple sections of the second plate are moved out of the receiving cavity, so that the attachment portion abuts against the positioning groove, forming a support structure to support the electronic device; the second plate is folded and adsorbed into the receiving cavity, the thickness of the second plate just fills the receiving cavity of the first plate, so that the inner and outer surfaces of the first plate remain flat, without discontinuities or steps, and the second plate does not increase the thickness of the first plate, reducing the weight by 30%, making it convenient for daily use and carrying.

This utility model belongs to the field of connector technology and provides a socket connector, including a housing and a contact fixed inside the housing. The housing has a groove extending from the edge of the housing along its width, exposing the solder cup of the contact within the groove. The groove has a through-hole extending through to the back of the housing along its thickness. A shielding sheet is fixed to the back of the housing. In this application, the through-hole extending to the back of the housing within the groove, combined with the shielding sheet fixed to the back, allows the shielding layer of the cable fixed to the contact to be soldered to the shielding sheet through the through-hole, thereby meeting the shielding requirements of different cables transmitting signals within the socket connector.
