  • Patent number: 10658766
    Abstract: A direct clamp terminal for connecting a conductor in the form of a flexible stranded conductor includes a housing with a chamber and an insertion conduit for inserting the conductor into the chamber. A bus bar or a clamping cage is provided in the housing and a clamping spring is located in the chamber and acts as a compression spring for securing the electrical conductor to the bus bar or the clamping cage in the area of a clamping point. The clamping spring has a clamping limb that can be pivoted about a pivoting axis and that can be shifted from a detent mode in which it is locked in a detent position into a clamping mode in which it is released from the detent mode and presses the electrical conductor against the bus bar or the clamping cage. The clamping limb can be released from the detent mode using two different shifting devices.

  • Patent number: 9263861
    Abstract: A module latching arrangement for mounting and dismounting on a generally U-shaped support rail at least two module base bodies arranged orthogonally above and extending transversely across the support rail, each of the base bodies having a pair of bottom corner portions arranged on opposite sides of the support rail. At least one foot member is connected for horizontal longitudinal sliding movement relative to one of the base body corner portions relative to the adjacent support rail horizontal flange portion. A lateral displacement arrangement on the foot member is operable, when the foot member is displaced from a locked position toward an unlocked position relative to the support rail, to displace the first base body laterally away from an adjacent second base body mounted on the support rail. The foot member is latched in either a locked or an unlocked position relative to the base member.

  • Patent number: 8764497
    Abstract: An electrical contact arrangement includes a planar conductive metal blank having sections that are foldable to define pairs of orthogonally arranged component contacts and bus blade contacts. Connected with a first pair of opposed side edges of a horizontal rectangular core section of the blank are a pair of rectangular component contact sections that are upwardly bent to define a pair of component contacts for receiving therebetween an electrical component, such as a printed circuit board. Connected with the orthogonally arranged second pair of opposed side edges of the core section are a pair of rectangular support sections that are bent downwardly, whereby a corresponding pair of bus blade contact sections connected with corresponding edges of the support sections extend in vertical parallel spaced relation to define a pair of bus blade contacts adapted for insertion between the downwardly bent support sections of a corresponding second electrical contact arrangement.

  • Patent number: 7513800
    Abstract: A terminal block connecting apparatus includes first and second support members displaceable from a disengaged condition toward an engaged condition in which corresponding main terminal blocks are brought into electrical engagement, characterized by the provision of first and second test terminal blocks connected with the support members for electrical engagement when the first and second support members are in an intermediate condition between the disengaged and engaged conditions. One of the test terminal blocks is supported by a carrier member for movement relative to the associated support member, whereby the test terminal blocks will remain in electrical engagement during displacement of the support members between the test and connected conditions. A friction retaining arrangement serves to resist displacement of the carrier member relative to its associated support member.
