A semi-finished product for manufacturing an electrical contact element includes a first workpiece having a front side and a rear side opposite the front side, a second workpiece, and a window extending through the first workpiece. The first workpiece and the second workpiece are both metallic. The rear side of the first workpiece is closer to the second workpiece than the front side. Through the window, a surface of the second workpiece is accessible from the first workpiece. The window has a base area that, starting at the front side of the first workpiece, increases toward the second workpiece.

A floating electrical connector includes a housing with a tubular portion. An axis is defined in a center of the tubular portion. Several floating terminals are arranged around the axis and are partially connected. Each floating terminal has an inner terminal sheet on an inner side and a spring structure on an outer side. Each spring structure is connected to one of the inner terminal sheets. A portion of the inner terminal sheet is inserted into the tubular portion and arranged along an inner peripheral surface of the tubular portion. The portion of each inner terminal sheet located in the tubular portion has an electronic contact bulging inward. Several external pins are electrically connected around the floating terminals. When a conductive pin is inserted into the tubular portion, the spring structures could elastically deform, allowing the tubular portion to adapt to a horizontal deviation or a skew deviation of the conductive pin, providing a greater tolerance for alignment deviations.

A terminal fitting 13 includes a tubular portion 30, an elastic contact portion 33, and an extended portion 35. The tubular portion 30 extends in a front-rear direction and has an open front surface. The elastic contact portion 33 is disposed in the tubular portion 30, extends in a front-rear direction, and has a rear end directly or indirectly connected to the tubular portion 30 and a front end that is a free end. The extended portion 35 extends from the tubular portion 30 and opposes the elastic contact portion 33 in a direction in which the elastic contact portion 33 bends. The extended portion 35 is disposed at a position exposed on a front surface side of the tubular portion 30.

A connector includes a terminal fitting that includes a terminal connection section, and a housing that includes a terminal accommodating section in which the terminal fitting is inserted into a terminal accommodating chamber in the terminal accommodating section in a terminal insertion direction and accommodated at an accommodation completion position, wherein the terminal connection section is a tubular section bent in a tubular shape with end surfaces of two end portions facing each other, and includes a recess that is recessed from a distal end of the terminal connection section on a terminal insertion direction side, in a terminal removal direction opposite to the terminal insertion direction, the terminal insertion direction being a tube axis direction.

An electrical connection terminal for a vehicle is capable of securing structural stability of an electrical connection with a mating terminal. The electrical connection terminal includes a terminal body, provided with a pair of spring couplers facing each other with a predetermined distance therebetween, and a pair of contact springs, respectively assembled to the pair of spring couplers and configured to electrically connect the terminal body to a mating terminal by being brought into contact with the mating terminal inserted between the pair of spring couplers, wherein the contact spring includes a spring body assembled on an outer side of the spring coupler, and a plurality of mating terminal contacts provided independently of each other on the spring body and elastically brought into contact with the mating terminal when the mating terminal is inserted between the pair of spring couplers.

An electrical connector for charging has a connector base, a first conductive terminal, a second conductive terminal, and an insulation base. The first conductive terminal is mounted in the connector base and has an upper chamber and a lower chamber. The second conductive terminal is located in and coaxial with the first conductive terminal and is electrically isolated from the first conductive terminal. The insulation base is mounted between the first and the second conductive terminals. An end of the second conductive terminal is located in the upper chamber and another end protrudes out of a bottom of the insulation base. The insulation base has at least one first groove lower than an imaginary datum plan and at least one platform higher than the imaginary datum plane and coaxial with the first groove. By the first groove and the platform, the creepage distance is increased.

An elastic terminal includes a first base having an annular shape and a plurality of elastic sheets extending from the first base in an axial direction. A slit is formed between a pair of adjacent elastic sheets. The plurality of elastic sheets include a plurality of sets of elastic sheets, each elastic sheet of each set of elastic sheets has a plurality of electrical contact portions protruding inwardly radially. The electrical contact portions of one set of elastic sheets are arranged on a same circumference and the electrical contact portions of different sets of elastic sheets are staggered with respect to each other in the axial direction.

A header power connector includes a header housing assembly including an inner housing received in a cavity of an outer housing. The inner housing has upper and lower openings open to a terminal channel configured to receive busbars. The inner housing is movable relative to the outer housing to accommodate misalignment of the busbars in the terminal channel. A terminal is received in the terminal channel having a terminal base, an upper mating end and a lower mating end. The upper mating end includes an upper socket flanked by upper spring beams that receives the first busbar and the lower mating end includes a lower socket flanked by lower spring beams that receives the second busbar. The terminal is movable in the terminal channel to accommodate misalignment of the first busbar and the second busbar in the terminal channel.
