Patent number: 9490596Abstract: An electrical contact assembly includes a pair of contacting members and a cable receiving member fixed with the contacting members. Each of the contacting members is in a shape of sheet and opposite to each other. The pair of contacting members is formed separately and defines a front-to-rear direction. The cable receiving member is formed separately from the pair of contacting members or is formed integrally with one of the contacting members. As the pair of contacting members is formed separately, the manufacturing process is simple and the quality is easy to control. The symmetry accuracy of the pair of contacting portions will also be controlled perfectly. As a result, a power loss of an electric current will be decreased.Type: GrantFiled: September 23, 2015Date of Patent: November 8, 2016Assignee: ALLTOP ELECTRONICS (SUZHOU) LTD.Inventors: Wang-I Yu, I-Hung Cheng, Shang-Ming Wu
