A connector for electrical contacting that includes a body configured to mechanically retain at least one electrically conductive contact, which is accessible on an exit side of the body for electrically contacting at least one other electrical contact. The body is constructed from at least two different components, with a first component of the at least two different components at least substantially forming the exit side and being made from a fire-retardant plastic, and a second component of the at least two different components having an ignition point which is lower than an ignition point of the first component of the at least two components, and the second component of the at least two different components having an elasticity which is greater than an elasticity of the first component of the at least two different components.

The invention relates to a connection element for electrically connecting an individual line which has a concentric conductor arrangement (32) and a central passage (33) for a cooling fluid. The connection element comprises an electrically conductive housing (2) with a sleeve-shaped pressing portion which is suitable for producing a press connection to the concentric conductor arrangement (32). The electrically conductive housing (2) here has an internal cooling passage (10) with a connection opening (11) for an external cooling line, said cooling passage leading into a space surrounded by the sleeve-shaped pressing portion. In addition, the connection element comprises a counterpressure element (3) which can at least partially lie in the space surrounded by the sleeve-shaped pressing portion. The counterpressure element (3) is furthermore configured to support the concentric conductor arrangement (32) on the inner side thereof when the sleeve-shaped pressing portion is compressed during the production of a press connection. The invention furthermore relates to a fluid-coolable individual line unit and to a charging cable having a charging connector.

A filter connection for a smoke evacuation device includes a filter canister assembly and a socket. The filter canister assembly has a cross-sectional shape with only one line of symmetry that corresponds to a cross-sectional shape of the socket so that the filter canister can only be inserted into the socket in one orientation. One or more key notches on the filter canister may also ensure that the filter is properly installed. A seal creates an airtight boundary between the filter canister and a recess of the socket so that a sealed path in communication with the smoke evacuation device is established before the filter canister is fully inserted into the socket. An electronic connection is made between the filter canister and the socket after the airtight boundary is created.

The present disclosure provides an electrical connector comprising a housing and a radiator. The radiator is disposed on the housing, comprising a fluid flowing space, a fluid input port, and a fluid output port. The fluid input port and the fluid output port are communicating with the fluid flowing space. Fluid flows through the fluid input port to the fluid flowing space. The fluid absorbs the thermal energy generated by a mating connector plugged into the electrical connector. The fluid absorbing the thermal energy generated by the mating connector flows through the fluid output port to external.
