Thus, the interface 102 is configured to provide both a first electrical connection 104 between the first conductor 106 and the second conductor 108 and a second electrical connection 110 between the third conductor 112 and the fourth conductor 1 14. The first conductor 106 may be described as a first electrical conductor 106. The second conductor 108 may be described as a second electrical conductor 108. The third conductor 112 may be described as a third electrical conductor 112. The fourth conductor 114 may be described as a fourth electrical conductor With reference to Figs. 9 to 11, the first conductor 106 may comprise or may consist of any one of: a first busbar 113 and a first electrical cable 115. The third conductor 112 may comprise or may consist of any one of: a second busbar 117 and a second electrical cable With reference to Figs. 1 to 6, the interface 102 includes a plurality of electrically conductive members 116a, 116b, i.e. two or more electrically conductive members 116a, 116b. Each one 116a, 116b of the plurality of electrically conductive members 116a, 116b may be made of any suitable electrically conductive material, such as a material comprising or consisting of a metal or a metal alloy, for example copper. However, other materials are possible. Each electrically conductive member 116a, 116b of the plurality of electrically conductive members 116a, 116b may comprise, or consist of, an electrically conductive pin 118a, 118b. Each electrically conductive member 116a, 116b of the plurality of electrically conductive members 116a, 116b, for example each electrically conductive pin 118a, 118b, may have one of: a circular cross- section and an oval cross-section. With reference to Figs. 1, 2 and 4, in the shown embodiment shown, the cross-section of the electrically conductive member 116a, lO116b is Circular. However, other cross-sections for the electrically conductive member 116a, 116b are possible.
The interface 102 includes a holder 120 for holding the plurality of electrically conductive members 116a, 116b. The holder 120 may be at least partly, or entirely, made of an electrically insulating material. The electrically insulating material of the holder 120 may for example be a polymer or a polymer composite, for example with sufficient dielectric strength. For example, the electrically insulating material of the holder 120 may including fibres, such as glass fibres. However, other electrically insulating materials, for example with sufficient dielectric strength, for the holder 120 are possible. For example, the exterior of the holder 120 may be made of an electrically insulating material while the core of the holder is made of any other material, for example any composite.
With reference to Figs. 1 to 6, the electrically conductive members 116a, 116b of the plurality of electrically conductive members 116a, 116b are spaced apart from one another, i.e. placed with a distance 121 to one another, the distance 121 being indicated in Figs. 2 and 5. With reference to Figs. 2, 5 and 6, in the shown embodiment, the distance 121 between one 116a, 116b of the plurality of electrically conductive members 116a, 116b and another one 116a, 116b of the plurality of electrically conductive members 116a, 116b is attained, or provided, by a plurality of though holes 122 formed, or defined, by the holder 120. With reference to Fig. 6, each through hole 122 of the plurality of through holes 122 is complementary to one 116a, 116b of the plurality of electrically conductive members 116a, 116b, i.e. the shape of the through hole 122 is adapted to the shape of the electrically conductive member 116a, 116b. Thus, for example, when the cross-section of the electrically conductive member 116a, 116b is circular, then the cross-section of the through hole 122 is circular, or an inner wall 123 of the through hole 122, i.e. the inner wall 123 that defines the through hole 122, forms a cylindrical hole into which the electrically conductive member 116a, 116b fits, for example snugly fits, i.e. fits in a snugging manner. Each through hole 122 of the plurality of through holes 122 holds one 116a, 116b of the plurality of electrically conductive members 116a, 116b. There may be a small gap or play between the electrically conductive member 116a, 116b and the inner wall 123 of the through hole lO122 holding the electrically conductive member 116a, 116b, to allow for the electrically conductive member 116a, 116b to laterally expand due to elevated temperatures when transferring electric power or electric current at a high voltage, for example a voltage above 60 V and up to 1500 V. These elevated temperatures may also be considered when selecting the material of the holder 120. For example, the material of the holder 120 may be configured to withstand elevated temperatures as a result of the transfer of electric power or electric current at a high voltage, for example any voltage mentioned above or below.
