Each sub-connector includes: an insulating base 100, on which a male connector 101 and a female connector 102 are provided; a number of contact parts installed on the insulating base 100 for power supply and / or signal transmission; when one of the sub-connectors is rotated by a certain angle around a set rotation axis, its male connector 101 is inserted into the corresponding female connector 102 on the other sub-connector, and its contact parts are electrically connected to the corresponding contact parts on the other sub-connector.

[0038] In this embodiment, the rotation axis of the sub-connector is the Y-axis. When one of the sub-connectors is rotated 180° around the Y-axis and then inserted into each other along the Z-axis, its male connector 101 is inserted into the corresponding female connector 102 on the other sub-connector, and its contact parts are electrically connected to the corresponding contact parts on the other sub-connector.

[0039] In this embodiment, the male connector 101 is a column with a water-drop-shaped cross-section, and the female connector 102 is a hole with a water-drop-shaped cross-section. The male connectors 101 and the female connectors 102 on the two sub-connectors cooperate with each other for insertion connection, playing a role of guiding and positioning to achieve the correct docking of the contact parts on the two sub-connectors.

[0040] In this embodiment, a protection plate 103 is provided on the insulating base 100. After the two sub-connectors are inserted into each other, all the contact parts are located in the closed space formed by the protection plate 103, playing a role of protection and shielding.
