A quick-change structure for liquid-cooled charging gun, relating to the field of new energy electric vehicle charging, comprises a charging connector main assembly; one side of the charging connector main assembly is fixedly connected with a terminal fixing assembly, and a detachable quick-change terminal is arranged inside the terminal fixing assembly; the detachable quick-change terminal is fixedly connected to the charging connector main assembly, the front side of the charging connector main assembly is provided with a detachable quick-change gun connector head assembly. The detachable structure realizes effective saving of excessive maintenance costs, labour-hours and material costs. Worn out terminals can be completely replaced within a few minutes after the power is confirmed cut off, and no other actions are required on the charging connector end or harness end. Merely using special tools to disassemble the terminal that needs to be replaced, reassembling and resetting, the quick replacement of wearing parts can be done. Maintenance costs and technical ability requirements for maintenance and replacement are lowered, and rapid replacement and maintenance is realized.

An arrangement for plug-connecting electrical connections through a housing, in particular a device for driving a compressor. The arrangement exhibits at least one plug-in connection with at least one plug-in connector for transmitting electrical energy, as well as one mounting element for mounting the at least one plug-in connector. The mounting element can be fixed on the housing. The mounting element exhibits on one inner surface of the housing, which encloses the volume, an opening for mounting a fastening element for fixing the mounting element on the housing. The opening is produced in such a way that it starts from the inner surface, extends into the mounting element and ends in the mounting element. The fastening element is arranged in such a way that it is inserted into the opening from the volume enclosed by the housing through a pass-through opening, that is produced in the housing.

An electric wire and terminal connecting construction has an electric wire having an insulation covering portion where a conductor portion is covered with an insulation material and a conductor exposed portion where the insulation material on an end portion of the electric wire is removed, a terminal including a crimping portion crimped to the conductor exposed portion to thereby be connected to the electric wire, and a seal portion covering the conductor exposed portion exposed from the terminal, wherein the seal portion has an external resin portion forming an outer surface side of the seal portion and made from a thermoplastic resin and an internal resin portion made from a thermoplastic resin of which a fusing point is lower than that of the external resin portion and forming an inner surface side of the seal portion, and is divided so as to be attached to the conductor exposed portion.

An electrical connection component for a machine cable is described. The electrical connection component is suitable for transmission of power with voltage levels greater than or equal to 1 kV and comprises at least one electrical conductor arranged for electrically coupling with a further electrical conductor of another electrical connection component. The electrical connection component comprises a housing having an internal region, and having a machine cable end, a connection end and a plurality of electrically insulating components positioned within the housing, at least one of the electrically insulating components being arranged so as to form-fit with a further one of the electrically insulating components. A portion of the internal region of the housing that is located at the connection end of the housing, and that would not otherwise be filled with the at least one electrical conductor and/or an associated flame path, is filled by the electrically insulating components.
