A terminal connection structure for a rotary machine which electrically connects the rotary machine and a terminal block of a power control unit, comprises a terminal including a layered portion connected to a winding of the rotary machine and formed by layering at least a first conductor portion and a second conductor portion; and a fastening member fastening the terminal and the terminal block of the power control unit.

An electrical contact element (1) for transmitting high currents has a connection region (A) and a contact region (K). The connection region (A) has a cylindrical opening (2) and the contact region (K) has a cylindrical passage opening (3). The opening (2) and the passage opening (3) are oriented orthogonally relative to each other and a peripheral contact strip (4) is arranged within the cylindrical passage opening (3).

A terminal block structure includes an insulative base, a conductive terminal, a toggle member and an elastic clamping piece. The insulative base has a chamber, a wire hole and an opened trough communicating with the chamber. The wire hole and the opened trough are located on the same side of the insulative base. The conductive terminal is fixed in the chamber. The toggle member has a main body, a stem and a pressing portion extended from the main body. The main body has a pivoting portion pivotally connected to the insulative base. The stem projects to outside of the insulative base from the opened trough and is movable on a lateral side of the wire hole. The elastic clamping piece is disposed in the chamber. An end of the elastic clamping piece is pressed by the pressing portion to operably open or close the wire hole.

An Insulation Displacement Contact Compliant connector system (IDCC) which includes a housing, header pins, and a Printed Circuit Board (PCB). Each header pin has at least a single barb to be retained into the housing. Each pin has a blade for contacting a wire. A compliant feature on the pin retains itself into holes in the PCB. The housing has a negative space similarly shaped to the pin. The housing includes a strain relief which provides a lead-in for a wire. When the system is fully assembled, the pins reside in the housing, and exit through the housing and into and through respective holes in the PCB. A wire can be inserted into the housing once the pins reside in the housing. There are several options for the assembly process including a) a pin-to-housing insertion process; b) a housing assembly-to-PCB process or a connector-to-PCB process; and c) a wired housing assembly-to-PCB assembly process or a wire harness-to-PCB assembly process.

A connector assembly includes an insulative housing, first and second conductive ground wafers (see e.g., 661 and 663) and a plurality of grounding links. The insulative housing has a plurality of conductive signal terminals disposed therein (see e.g., 662). The insulative housing has opposite side surfaces and a plurality of openings therein extending between the side surfaces. The second ground wafer is spaced from and parallel to the first ground wafer. The grounding links are electrically connected to one of the ground wafers and extend towards another of the ground wafers and extend through the openings in the housing.

A terminal for contacting at least one contact pin includes: a socket carrier; and at least one socket, which includes in each case a first contact arm connected to the socket carrier and a second contact arm connected to the first contact arm via a resilient connection, which second contact arm is pivotable, in a space between the first contact arm and the socket carrier, between a vacant position and an occupied position. In the vacant position the second contact arm is arranged at a first distance from the socket carrier and in the occupied position the second contact arm is arranged at a second distance from the socket carrier which is smaller than the first distance. A restoring force of the resilient connection in the occupied position contacts the respective contact pin between the first contact arm and the second contact arm.

A connecting element for mounting an electrical circuit board to an electrical flat conductor, in particular a busbar, has a flat or substantially flat mounting surface for applying and mounting the connecting element to the circuit board, and a tulip contact for receiving the flat conductor in an electrically contacting manner. The tulip contact includes at least one clamping element and a support element, between which a receptacle for the flat conductor is provided, and wherein the tulip contact preferably extends at a mounting angle greater than 45° and less than 135° with respect to the mounting surface. An electrical circuit board having such a contact element, a terminal block having such an electrical circuit board, and a method for automated mounting of such a terminal block are also provided.

A power input terminal block includes terminals received in terminal channels of a housing each having a main body defining a wire pocket receiving a supply wire and a take-off tab electrically connected to the main body. The power input terminal block includes clamp contacts coupled to the take-off tabs each having a base, a spring beam extending from the base, and a cap extending from the spring beam having a poke-in window configured to receive a take-off wire. An edge defining the poke-in window engages the take-off wire and pulls the take-off wire against the wire side of the take-off tab. The power input terminal block includes release levers coupled to the housing to move the spring beam to an extended position to allow loading and removal of the take-off wire from the clamp contact and the take-off tab.

A connection apparatus for connecting electrical devices, in particular electric motors to an AC system, has a housing which has at least one housing portion. A plurality of first and second conductor terminals are arranged in the at least one housing portion. Each conductor terminal has at least one or two or more individual terminals and a configuration plug. The configuration plug electrically connects individual or a plurality of the first and/or second conductor terminals in at least two different positions in order to obtain at least two different circuit types. The configuration plug is rotatably or slidably guided in or on the housing or at least on the at least one housing portion. Due to this relative movement, plug can be rotated and/or displaced into at least two different positions, in order to provide the at least two different circuit types.
