Abstract: A cable winding device comprises a case, a reel disc, a cable, and a cable locking structure. The case comprises a first case element and a second case element. The reel disc is disposed between the first case element and the second case element, wherein the reel disc has a leaf spring. The cable is wound on the reel disc. The cable locking structure has a fixing part and at least partially penetrates the first case element and the reel disc. When a pulling operation of the cable causes the leaf spring to be sustained against the fixing part, a desired length of the cable is pulled out from the case and locked. When the cable locking structure is pressed and the fixing part is detached from the leaf spring, the cable pulled outside the case is rewound on the reel disc.

Abstract: An integrated electric connector includes a main body, a first electric connector, a casing, a second electric connector, a third electric connector, and a guiding member. The first electric connector is at least partially protruded from the main body and connected with a transmission cable. The second electric connector is installed in the casing, and connectable with the first electric connector. The third electric connector is disposed on the casing and connected with the second electric connector. The guiding member is connected with the casing. The first electric connector is guided by the guiding member to be detachably connected with the second electric connector. The first electric connector is directly connected with the electronic device, or the first electric connector is indirectly connected with the electronic device through the second electric connector and the third electric connector.
