A cable connector includes a soft body. The soft body has at least one connecting portion. An outer wall surface of the connecting portion is provided with a hard casing. The soft body is made of a soft material, such as rubber and silicone rubber. The hard casing is made of a hard material, such as plastic, and has higher rigidity than the soft body. When a bushing of a cable is inserted into the connecting groove of the connecting portion, the hard casing is configured to resist deformation, so that the connecting portion will not be deformed by insertion of the bushing, thereby improving the electrical connection between the cable connector and the bushing.
