A connector is disclosed. In an embodiment, the connector includes a first connection part and a second connection part. The first connection part and the second connection part form a groove suitable for accommodating a circuit board when the first connection part and the second connection part are assembled together, and elastic parts are disposed on opposite inner surfaces of the groove. Furthermore, a corresponding three-way transmission and conversion circuit module is disclosed, including the connector.

Example of systems with rotatable port units are described. In an example, a system includes a control unit, a first port unit with a first set of ports coupled to the control unit, and a second port unit with a second set of ports coupled to the control unit. The second port unit is mounted on the first port unit and is rotatable with respect to the first port unit. The control unit is to enable a subset of ports from the second set of ports and the first set of ports based on a rotational position of the second port unit with respect to the first port unit.

The present disclosure provides a converter, including a housing and a three-pole plug pin assembly. The three-pole plug pin assembly includes a toggle button assembly, and the toggle button assembly is configured to be able to move between a first position and a second position. When the toggle button assembly is at the first position, the toggle button assembly is capable of driving an L-pole plug pin, an N-pole plug pin and an earth-pole plug pin to extend out of the housing. When the toggle button assembly is at the second position, the earth-pole plug pin is capable of being received in the housing under an action of a first elastic member.

The present invention relates to a travel plug adapter, which will also be referred to herein as a travel adapter, for short. Using such an adapter it is possible to insert power plugs of a certain (domestic) standard into the outlets present at the travel destination. The travel plug adapter (10) is particularly one which has a housing, a plug receptacle (16) and at least a first plug (34) of a first standard and a second plug (36) of a second standard, wherein each plug is assigned an actuation slider (22, 24, 26), which is guided outwardly through a slide slot (42) in the housing and is designed to displace the plug between a standby position, in which the plug is disposed substantially inside the housing, and a usage position, in which the plug is usably disposed outside the housing, wherein the first plug comprises a plug body and a first contact pin and a second contact pin, wherein, in the usage position, both the plug body and the first contact pin and the second contact pin are usably disposed outside the housing, and, in the standby position, both the plug body and the first contact pin and the second contact pin are disposed in the housing, wherein the second plug comprises a third contact pin and a fourth contact pin, and the third contact pin and the fourth contact pin are also guided in the plug body of the first plug.
