Transferring electric signals, and electric energy
Terminal Block ,Power Cable
Terminal Block and power cable adapted to unitization of inverter and motor
To cope with unitization of inverter and motor, a low profile is achieved by configuring the terminal into water cutoff type with mold/adhesive. In the case of molding both terminals, and making the wire short, the braided wire of the conventional shield of package type may be disadvantageous in that it has to be preliminarily routed, and is likely to split upon cutting. Those problems are solved by employing the high-density braided wire which secures to keep its shape equally well post-installation. Furthermore, the newly developed wire with flexible wire-coating has solved the problem of operational degradation thanks to the reduced wire length.
High-voltage Wires For HV
Employed for the high-voltage circuit installed in next-generation vehicles, for example, hybrid vehicle (HEV), plug-in hybrid vehicle (PHV), electric vehicle (EV) and the like. Employed as the harness component for supplying electricity to various devices such as high-voltage battery, motor, and inverter.
Copper and aluminum are used for forming the conductor. The use of aluminum instead of copper has resulted in substantial weight reduction while maintaining high reliability. The insulator exhibits 2 types of excellent heat resisting property, for example, resistance against temperatures of 120℃ and 150℃. It can be used in the high-temperature environment of the vehicle.
Referring to the crosslinking process (N.B.) applied to the insulator to improve the heat-resistant property of the wire, the heat-resistant wire that allows crosslinking with steam (developed through the electron beam irradiation crosslinking process, which requires an electron beam irradiation device) was developed and made into a product.
N.B. : Crosslinking among chain macromolecules
Employed for control circuits and sensors, which are installed in various types of automobiles such as gasoline-powered vehicle, hybrid vehicle (HEV), plug-in hybrid vehicle (PHV), and electric vehicle (EV). In addition to the function of supplying electricity to the respective circuits, the cable has the shield layer functioning to shield external noise. Noise shielding ensures prevention of circuit malfunction.
The shield structure has three types including braided structure, horizontal winding structure, and metallic foil tape, which can be selectively used in accordance with the required noise shielding level. Copper is used for forming the braided structure and the horizontal winding structure. Copper and aluminum are used for forming the metallic foil tape. The number of wire cores ranges from 1 to 8.
For reduction of thickness and weight of the shield cable, the thickness of the insulator of the wire core is reduced. Thinning of the sheath for protecting the shield layer secures thinning and weight reduction of the shield cable while maintaining high reliability.
