step three: when the data wire (9) is damaged, the rear cover (10) is taken down through the starting-up groove (11), the partition plate (22) is taken out, the data wire (9), the central column (21), the torsion spring (23) and the wire containing roller (24) slide out from the cavity inside the connector (2) along with the sliding block (25), the damaged data wire (9) is dismounted, the connector connected with the data wire (9) is drawn out from the connector containing groove (8) at the upper end of the connector (2), the tail end of the new data wire (9) connected with the connector is inserted into the cavity from the front end of the connector containing groove (8), the data wire (9) is drawn out from the cavity and is connected and fixed with the conducting wire on the surface of the wire containing roller (24), the data wire (9), the central column (21), the torsion spring (23), the wire containing roller (24) and the sliding block (25) are pushed back into the cavity, and the replacement of the data wire (9) is completed, the cavity between the partition plate (22) and the rear cover (10) is convenient for storing and taking small mobile phone accessories such as memory cards, card pins, USB flash disks and the like.
