Abstract
An electrical contact assembly has a contact carrier formed with symmetrically opposed rows of comb-like guides, opposed rows of double-ended contact fingers mounted in the guides, a first contact piece supported by the contact carrier between the contact fingers at one end of the fingers and a second contact piece for insertion between the contact fingers at the opposite end of the fingers. For resiliently urging the fingers to contact the respective contact pieces, a pair of spring elements are attached to the contact carrier. Each spring element has a central web mounted on the carrier and opposite rows of arms extending from the web to engage opposite portions of the respective fingers.
Claims12
An electrical contact assembly comprising a contact carrier having integral symmetrical opposed rows of comb-like guides, opposed rows of double-ended contact fingers mounted in the respective guides, a first contact piece supported by the contact carrier between the contact fingers at one end of the fingers, a second contact piece for insertion between the contact fingers at an opposite end of the fingers, each of said guides comprising a base and a row of spacing elements extending outwardly from said base, the fingers having central portions between the respective ends of the fingers, said central portions being located between respective spacing elements of the comb-like guides outside of the respective bases relative to the contact pieces, and a pair of spring elements mounted on the carrier each for resiliently urging a respective row of the fingers to contact the respective contact pieces, each spring element comprising a central web mounted on the carrier and opposite rows of arms extending from the web to engage opposite portions of the respective fingers.
In an electrical contact assembly comprising a contact carrier having symmetrically opposed rows of comb-like guides, opposed rows of double-ended contact fingers mounted in the respective guides, a first contact piece supported by the contact carrier between the contact fingers at one end of the fingers, and a second contact piece for insertion between the contact fingers at an opposite end of the fingers, the improvement comprising a pair of spring elements mounted on the carrier each for resiliently urging a respective row of the fingers to contact the respective contact pieces, each spring element comprising a central web mounted on the carrier and opposite rows of arms extending from the web to engage opposite portions of the respective fingers, wherein the web of each spring element has a tongue at each end engaging in an opening in an end wall of the carrier to mount the element on the carrier, and wherein the opening has a form of two superposed rectangles of different widths and the tongue has spaced shoulders abutting the wall at opposite ends of one of the rectangles which is of smaller width thereby securing the spring element against displacement lengthwise of the web.
