    摘要： The present invention relates to a Cu-Ni-Sn-P-based copper alloy sheet having a specific composition, where (1) the copper alloy sheet is set to have an electrical conductivity of 32% IACS or more, a stress relaxation ratio in the direction parallel to the rolling direction of 15% or less, a 0.2%-proof stress of 500 MPa or more and an elongation of 10% or more; (2) the X-ray diffraction intensity ratio I(200)/I(220) in the sheet surface is set to be a given value or less and at the same time, anisotropy in the stress relaxation resistance characteristic is reduced by fining the grain size; (3) the texture of the copper alloy sheet is set to a texture such that the distribution density ofB orientation and the sum of distribution densities ofB orientation, S orientation and Cu orientation each is set to fall in a specific range and bendability is thereby enhanced; or (4) the dislocation density measured using the value obtained by dividing the half-value breadth of the X-ray diffraction intensity peak from {200} plane in the copper alloy sheet surface by the peak height is set to a given value or more and press punchability is thereby enhanced. The Cu-Ni-Sn-P-based copper alloy sheet of the present invention is excellent in the properties required for a terminal or connector and further (1) has excellent strength-ductility balance, (2) satisfies the stress relaxation resistance characteristic in the direction orthogonal to the rolling direction, (3) has excellent bendability, or (4) has excellent press punchability.

    摘要： A connector is mateable with a mating connector which includes a mating contact having a mating contact point. The connector comprises a contact and a holding member which holds the contact. The contact has a contact portion. When the connector and the mating connector are mated with each other, the mating contact point slides on and is in contact with the contact portion. The contact portion has a first plated layer as its outermost layer and a second plated layer located under the first plated layer. The first plated layer is made of silver or silver alloy and has Vickers hardness not more than 90Hv. The second plated layer is made of silver or silver alloy and has Vickers hardness not less than 100Hv.

    摘要： The invention relates to an electrical connection for medium and high voltage switchgears, with an electrical terminal of a switchgear, wherein an electrical contacting surface of the electrical terminal is electrically connected with a contacting surface of an external electrical connector part via a connecting system, according to the preamble of claim 1. In order to to ensure a low restistance electrical connection, the invention is, that the connecting system comprises a female screw thread in a stud hole of the electrical terminal as well as in a stud hole of the external connector part, and a stretch bolt with male screw threads at each opposite ends, screwed into the female screw thread of the electrical terminal with one end of the stretch bolt, and into the female screw thread of the external connector part at the other end of the stretch bolt.
