The invention belongs to the technical field of lighting lamp accessories and specifically relates to an electronic wire harness with self-bundling performance. The electronic wire harness comprises amain connector, an auxiliary connector, a fixing ring, a main buckle and an auxiliary buckle. The top of the main connector is electrically connected with a wire. The electrical output end of the wire is electrically connected with the auxiliary connector. The outer wall of the circumference of the wire is sleeved by the fixing ring. The left side wall and the right side wall of the fixing ring are connected with the main buckle and the auxiliary buckle respectively. According to the electronic wire harness with self-bundling performance, an inner groove with an inner hole can be formed in the front side wall of the main connector, so that the fixing ring can be conveniently arranged in the groove; fixation is realized through cooperation of a main nail and an auxiliary nail, and normal use of the harness is not influenced; when the wire harness is connected and needs to be bundled and stored, the main nail and the auxiliary nail are pulled to enable the fixing ring to be separated from the inner hole, a side plate is rotated to enable the main buckle and the auxiliary buckle to make contact with the wires at the two sides, and the wires are clamped in cooperation with the open groove, so that the three-wire-in-one purpose is achieved, use of external accessories is avoided, and the self-bundling mode is flexible and simple.
