A vehicle electric system has an electrical connection device to connect a power supply device and at least one electric/electronic apparatus to one another, and a filtering device, which is associated with the electrical connection device to at least limit interfering voltages and/or currents generated by the electric/electronic apparatus, is powered with the electric current supplied through the electrical connection device and is provided with at least two filtering modules mounted in series to one another and connected to one another in a releasable manner.

A contact support includes a bus bar and a contact spring, which has a clamping leg for clampingly contacting an electrical conductor between the clamping leg and a contact surface on the bus bar. The contact spring has a mounting leg for permanently fixing the contact spring on a fastening surface of the bus bar, the mounting leg being connected to the clamping leg. A snap element is formed on the mounting leg. A counter-surface is formed on the fastening surface such that, when the mounting leg is fixed on the fastening surface, the snap element engages behind the counter-surface to close a snap connection. When the snap connection is closed, a stop disposed on the mounting leg is firmly seated against a counter-stop formed on the fastening surface and eliminates longitudinal movability of the mounting leg relative to the fastening surface.

The present disclosure relates to wiring devices. In some embodiments, the wiring device may include wire terminals and/or termination mechanisms arranged and configured to electrically and mechanically couple an electrical wire to the wiring device. In some embodiments, the wiring device may be in the form of a commercial or industrial grade electrical receptacle including a wrap-around strap. Alternatively, in some embodiments, the wiring device may be in the form of a three-way switch. In addition, and/or alternatively, an improved spring clamp is disclosed.

A wiring terminal includes a metal lug, a current-limiting circuit board, and a metal spring plate. The metal lug is electrically connected to one end of a wire body of the conducting wire. The current-limiting circuit board is configured to limit a magnitude of a current, and is electrically connected to the one end of the wire body of the conducting wire. The metal spring plate is spaced from the metal lug in a first direction. The metal spring plate is electrically connected to the current-limiting circuit board. When the metal lug is pressed, the metal spring plate can be in conduction connection with the metal lug, and a resistance of the metal lug is smaller than that of the current-limiting circuit board. The wiring terminal can resolve a problem of emergence of electric sparks in a wiring process, reduce potential safety hazards, and implement a safe and reliable connection.

A female electrical terminal comprising a hollow cylindrical housing and a contact spring. The contact spring including a first ring located within the housing, a second ring located within the housing spaced from the first axial end, and a plurality of corrugated contact strips extending axially from the first ring to the second ring.

A terminal includes a cylindrical body, a crimping portion, a plurality of resilient pieces, and a sleeve. The crimping portion is disposed at an end of the cylindrical body and crimps a wire onto the terminal. The plurality of resilient pieces extend from an other end of the cylindrical body and electrically connect a mating terminal inserted between the resilient pieces. The sleeve is sleeved on outer sides of the cylindrical body and the resilient pieces. The sleeve has at least one set of protrusions. Each protrusion protrudes from a side wall of the sleeve towards the cylindrical body. Each protrusion abuts against the cylindrical body and aligns with each other in a circumferential direction of the sleeve adjusting a coaxiality between the sleeve and each of the cylindrical body and the resilient pieces.

A spring-loaded terminal is designed as a direct plug-in terminal for connecting a conductor. The terminal includes a busbar for contacting the conductor, a clamping spring for retaining the electrical conductor in the terminal, and a retaining spring for latching the clamping spring in an open position so that the conductor can be inserted into a contact area. The clamping spring has a pivotable clamping leg and a clamping edge. The retaining spring has a pivotable pivoting leg having at least one retaining device as a first latching device. The clamping leg has a corresponding latching device cooperating with the retaining device of the pivoting leg in a latching state of the clamping leg. The clamping leg is adjustable from the latching state by displacing the electrical conductor into a clamping state in which the clamping leg is unlatched from the retaining device and presses the electrical conductor with the clamping edge of the clamping leg against the busbar. The latching device of the clamping leg is spaced from the clamping edge of the clamping leg.

A conductor terminal having a housing, a first spring-loaded clamping connection connecting a first electrical conductor, and a second spring-loaded clamping connection connecting a second electrical conductor. The first spring-loaded clamping connection is electrically connected to the second spring-loaded clamping connection. The first spring-loaded clamping connection has a first clamping spring and a first counter bearing, between which a first clamping point is formed where the first electrical conductor can be clamped between the first clamping spring and the first counter bearing. The second spring-loaded clamping connection has a second clamping spring and a second counter bearing, between which a second clamping point is formed where the second electrical conductor can be clamped between the second clamping spring and the second counter bearing. The first clamping point and the second clamping point are arranged in the interior of the housing at a distance from outer walls of the housing.

A conductor connection terminal with an insulation material housing having at least one conductor insertion opening for receiving an electrical conductor in a conductor insertion direction is described. At least one spring-loaded clamping connection for connecting an electrical conductor via elastic force is situated in the insulation material housing. The spring-loaded clamping connection has at least one busbar and a clamping spring with a clamping leg having a clamping edge for clamping the electrical conductor to a clamping point on a contact section of the busbar. The spring-loaded clamping connection, as a further component that is separate from the clamping spring and the busbar, has a connecting body via which the clamping spring is fixed to the busbar.

A connector includes a housing and a terminal. The housing includes a bottom portion, an extending portion, and a supporting portion. The extending portion protrudes from the bottom portion. The supporting portion is located in the bottom portion. The terminal is connected to the housing. The terminal includes a main body and an extending arm extending from the main body. The extending arm abuts against the supporting portion. The extending arm is wavy-shaped.
