A contact insert for a connecting terminal of a multiplicity of mutually isolated connection elements, designed in particular for printed circuit boards, with a spring force element being mounted symmetrically, with the spring force element designed with a simple section geometry and its simple mounting together with the advantageous connection to the contact insert, results in a closed terminal cage which makes it possible to reduce the physical height of the dielectric housing to a major The connecting terminal is used as a linking element in printed circuit board connection technology for providing a reliable supply to industrial electronics and economic individual wiring on printed circuits.

A bumping process is disclosed. The bumping process comprises the steps of: providing a wafer having a plurality of bonding pads and a passivation layer, wherein the passivation layer exposes the bonding pads; forming an UBM layer over the wafer to cover the bonding pads; forming two or more photoresist layers over the wafer, wherein the photoresist layers have different exposure and development characteristics; forming at least one or more stair-shaped openings in the photoresist layers by a single exposure corresponding to the bonding pads; filling solder into the stair-shaped openings to form a plurality of solder bumps; removing the entire photoresist layer. The bumping process can provide bumps with higher heights, so that the connection between chips and carriers becomes more reliable.

A crimping terminal joined with an aluminum electric wire, in which when the crimping terminal is crimped to the wire, a conduct-purpose crimping portion and a wire-hold crimping portion are formed at a crimping portion of a wire barrel of the crimping terminal. The crimping portion of the wire barrel is formed so as a curvature thereof is projected upwardly in a direction of moving a crimping die and so as a crimp height increases and a compression ratio decreases towards an insulation barrel of the crimping terminal. The curvature is shaped to have a constant degree of curvature, and is shaped to form a quadratic curve as a result of strictly adjusting a crimping force.

The invention discloses a dual-mode rear wheel active steering device. The dual-mode rear wheel active steering device comprises a steering motor, a main shaft and a mode switching assembly, wherein an input gear is arranged at the output end of the steering motor; one end of the main shaft drives the steering motion of a first rear wheel through a two-stage gear transmission system and a first rear wheel motion conversion mechanism, and the other end of the main shaft drives the steering motion of a second rear wheel through a planetary gear coupling mechanism and a second rear wheel motion conversion mechanism; the main shaft is provided with an intermediate gear, a transmission gear and a sun gear of the planetary gear coupling mechanism, and the intermediate gear meshes with the inputgear for transmission; and a mode switching input gear meshing with transmission gear is arranged at one end of the mode switching assembly, a mode switching output gear meshing with an inner gear ring of the planetary gear coupling mechanism is arranged at the other end of the mode switching assembly and is used for selectively driving or locking the inner ring of the planetary gear coupling mechanism by an electromagnetic clutch device, and the steering motor can drive the movement of a left wheel and a right wheel in the same direction in an uniform amplitude mode or the steering movement in the opposite direction by properly designing the gear speed ratio.
