A system and method for preparing and installing a graphite ground system is able to establish a durable conductive ground suitable for use in dissipating electrical current in conjunction with larger sensitive electronic installations. The method is provided with an excavation tool, an installation site, a volume of substrate, a volume of catalyst, a volume of conductive additive, a ground lead, and at least one regulated current source. The excavation tool is used to prepare the installation site for an in-situ preparation of the volume of substrate, the volume of catalyst, and the volume of conductive additive. The resultant conductive slurry is further modified with the integration of the ground lead, whereby the regulated current source may be electrically connected to earth (electrical ground). The conductive slurry is subsequently compacted and solidified into a conductive ground element, capturing the ground lead and ensuring a consistent electrical connection to ground.

The present invention disclosure relates to an intermediate connection structure of a power cable, which is capable of reducing heating of a connecting part of conductors of a pair of power cables connected through a joint box, enhancing a connected state of the conductors, and minimizing a diameter of the conductor connection part.

A disk having at least one electric connecting element is described. The disk has a substrate, and electrically conductive structure on a region of the substrate, a connecting element containing at least chromium-containing steel, and a layer of a soldering compound that electrically connects the connecting element to sub-regions of the electrically conductive structure.

A terminal metal part is provided which can suppress changes in characteristic regarding the connection while suppressing galvanic corrosion. In the terminal metal part, a tin plating layer is formed thicker in a crimping region with a conductor crimping lug than in an electric connecting region contactable with a mating terminal. With this, it is difficult for the conductor section and an alloy section as a base under the tin plating layer in the crimping region to come into a direct contact with each other, which can suppress galvanic corrosions. Furthermore, forming the tin plating layer can have less influence in the electric connecting region and changes in characteristics regarding the connection to the mating terminal can be suppressed.

The present invention discloses a charging socket lead frame assembly and a charging socket. The charging socket lead frame assembly has a lead frame which has a frame body and an electrical connection structure arranged in the frame body. The lead frame is adapted to be installed in a cavity of a charging socket, and a plurality of terminals of the charging socket are adapted to pass through the frame body. One end of the electrical connection structure is exposed from the frame body to electrically connect with a lead of a temperature sensor. The lead frame is arranged in non-electrical contact with at least one signal terminal of the charging socket. Therefore, the structure of the lead frame can be simplified and the manufacturing difficulty and cost can be reduced.
