Definitions
- the present disclosure relates to electrical connectors and more particularly to a self orienting electrical connector.
- USB Universal Serial Bus
- USB connectors and other data connectors typically include a female connector installed on an electronic device which receives a corresponding male connector which may be installed, for example, on a data cable.
- the connectors Since the male connector is physically inserted into the female connector, the connectors may become damaged if the male connector is accidentally impacted. Furthermore, in order to physically insert the male connector into the female connector, the connectors must be properly aligned. Aligning the connectors is sometimes difficult where one of the connectors is obscured. For example, USB connectors are often provided on a back-side of desktop computers. In such cases, users are sometimes faced with the difficult task of inserting a USB data cable into a complementary connector which is not visible.
