Disclosed in the present application are a cable connector and an electronic device. The cable connector comprises a socket (10) and a plug (20). The socket (10) has an insertion port (11) and a connection portion (12) for connecting to a first circuit board (1), wherein the insertion port (11) leads to the first circuit board (1). The plug (20) comprises a fixing member (21), an elastic connection member (22) and a cable line (23), wherein the elastic connection member (22) is fixed to the fixing member (21) and forms an electrical signal connection with the cable line (23); the elastic connection member (22) has an elastic contact portion (221); and the fixing member (21) can be inserted into the socket (10) by means of the insertion port (11), and the elastic contact portion (221) is in elastic contact with a connection contact point (3) on the first circuit board (1) so as to form an electrical signal connection. The electrical signal connection of the cable connector is short, thereby being beneficial to impedance matching between the cable connector and a cable, thus improving signal integrity. The cable connector has the advantage of fast and stable signal transmission.
