The invention relates to the technical field of dies, and particularly relates to a hexagonal terminal forming die, which comprises a die bottom plate. The die bottom plate is provided with a die fixing seat; an inner die seat is movably arranged in the die fixing seat; an outer die seat is fixedly arranged on the die fixing seat; a first groove and a second groove are arranged on the inner die seat; the first groove and the second groove are internally provided with a first elastic piece and a second elastic piece respectively; the first elastic piece is connected with a first crimping sliding block; the second elastic piece is connected with a second crimping sliding block; the outer die seat is provided with a third groove and a fourth groove; the third groove and the fourth groove are internally provided with a third elastic piece and a fourth elastic piece respectively; the third elastic piece is connected with a third crimping sliding block; and the fourth elastic piece is connected with a fourth crimping sliding block. The terminal is placed in the die, the terminal can be automatically crimped into a standard regular hexagon, a wire harness can be compactly crimped and is not likely to get loose, the wire is not broken, sparks are not generated in the power-on case, strong current can be borne, the manufactured wire harness terminal has high precision, the appearance is good, and requirements of a client can be totally met.

The invention provides a compression joint type power module which comprises a shell, a cover plate and an electric insulation substrate in compression joint with a cooling device. The shell is provided with a first surface and a second surface which are opposite to the cover plate and the electric insulation substrate respectively, the cover plate and the electric insulation substrate are assembled on the first surface and the second surface of the shell respectively, an annular inner groove is formed in the position of the second surface of the shell facing the periphery of the electric insulation substrate, a first elastic buffer part elastically abutted to the electric insulation substrate is embedded into the annular inner groove, and the first elastic buffer part is higher than the second surface of the shell so that the pressure of the electric insulation substrate in soft compression joint with the cooling device can be adjusted by the shell. As the elastic buffer part is embedded into the inner groove formed in the shell, a certain elastic buffer is provided, the electric insulation substrate can be protected from fracture, the pressure of the electric insulation substrate in soft compression joint with the cooling device can be adjusted, close compression joint of the electric insulation substrate and the cooling device is constantly ensured, heat resistance is reduced, and cooling efficiency is improved.

An intravascular stent especially suited for implanting in curved arterial portions or ostial regions. The stent can include an end region which is fabricated to have a greater radial strength than the remaining axial length of the stent. Such a stent is particularly suited for use in ostial regions, which require greater support near the end of the stent. The stent alternatively can include sections adjacent the end of the stent with greater bending flexibility than the remaining axial length of the stent. Such a stent is particularly suited for use in curved arteries. The stent can also be constructed with an end that has greater radial strength and sections adjacent the end with greater bending flexibility. Such a stent prevents flaring of the stent end during insertion.
