A method for attaching a contact element comprises steps for providing an electrical conductor with a conductive core and an insulating sheath, for detaching a sheath section of the sheath in an end region of the conductor for displacing the sheath section against the core in such a way that the sheath section protrudes beyond a longitudinal end of the core, and for crimping a contact element to the end region of the conductor in such a way that at least a part of the sheath section is being enclosed between the contact element and the core.

The present invention relates to an electric contact element that has at least one crimping strap which is configured and arranged to reach around the outer circumference of an electric conductor, at least in sections, at least in a fully crimped state of the contact element. Furthermore, the invention relates to an electric contact arrangement that has at least one electric conductor and at least one contact element that has at least one crimping strap which is crimped, at least in sections, around an outer circumference of the conductor. Finally, the invention relates to a method of producing an electric contact arrangement, at least one crimping strap of a contact element being crimped, at least in sections, around an electric conductor. In order to seal an interior of the contact arrangement as simply and effectively as possible and with long-term stability against the penetration of corrosive media, provision is made according to the invention such that at least one front protection strap of the contact element is aligned running, at least in sections, transversely to the at least one crimping strap and rests against the latter, a front section of the electric conductor being covered, at least in sections, by the at least one front protection strap.

The machine for cracking a connecting rod comprises an electro press with an electric motor (400) for actuating an expandable element. The electro press comprises a first S actuator part (410) and a second actuator part (430) arranged so that when the first actuator part is driven by the electric motor (400) from a first position to a second position, (a) the first actuator part (410) is first driven by the electric motor (400) from said first position (FIG. 12A) to an intermediate position (FIG. 12B), without displacing the second actuator part (430), and (b) subsequently the first actuator part (410) is further driven by the electric motor (400) from said intermediate position (FIG. 12B) to said second position (FIG. 12C), displacing the second actuator part from a non-expanding position to an expanding position.

A circuit board for a high speed communication jack including a rigid circuit board in the housing having a substrate, a plurality of vias extending through the substrate with each via being configured to accommodate a pin on the housing, a plurality of traces on a middle layer in the substrate, with each trace extending from a corresponding one of the plurality of vias, a first shielding layer on a first side of the middle layer in the substrate, a second shielding layer on a second side of the middle layer in the substrate, and a third shielding layer adjacent to the second shielding layer.

A crimping tool exchange device exchanges a first crimping tool for a second crimping tool, wherein each crimping tool, when at a processing position in a crimping press, produces a crimp connection connecting a conductor end of a cable to a crimp contact. The device includes first and second exchange units retaining the first and second crimping tools respectively. When one of the exchange units is arranged in an exchange position the retained crimping tool can be moved in a first direction between the processing position and the one exchange unit. The first exchange unit is moved linearly from the exchange position in a second direction, and the second exchange unit is moved linearly from the exchange position in a third direction that is different from the second direction, the second direction being at an angle relative to the third direction.

An interface structure connecting an electronic component to a circuit board. The interface structure includes a base defining an elongated through hole with a central axis and a coil spring retained in the elongated through hole. The coil spring has a proximal portion and a distal portion extending from the elongated through hole in an uncompressed condition and being offset at an angle with respect to the central axis. As the coil spring is compressed, the coil spring creates a force having a component substantially perpendicular to the central axis.
