Abstract
The terminal (2) comprises a stamped and formed metal pin socket (6) comprising a base (12) from which extend two contact springs (14) each comprising an L-cross section forward portion having identical parts (18 and 20) which extend at right angles to each other. Back from contact bosses (22) of the springs (14), each spring (14) has a longitudinal slot (28) which enables the parts (18 and 20) of each spring (14) to splay resiliently apart from each other when a square cross section pin (P) is inserted into the socket (6), without the pin insertion force or the contact force exerted by the contact bosses (22) against the pin (P), being excessive. These forces can be predetermined by suitably dimensioning the slots (28).
Claims10
An electrical socket terminal having an elongate stamped and formed metal socket comprising a tubular base having a forward end, and first and second elongate contact springs arranged in rotational symmetry and projecting forwardly from the base, each contact spring having a forward end and a rear end comprising two orthogonally arranged planar parts extending forwardly, each planar part being connected to the base at the rear end of said planar part and the planar parts being connected to their forward ends by a fold in the contact spring, which fold extends longitudinally of the socket and about which fold said planar parts of the contact spring are resiliently flexible by virtue of a slot separating said planar parts and extending from said fold towards the base, each planar part of each contact spring having projecting from the plane thereof a contact surface located rearwardly of, and adjacent to, the fold in the contact spring, each of the contact surfaces of the first contact spring facing a respective contact surface of the second contact spring, whereby said contact surfaces are engageable by an electrical pin introduced between the contact surfaces to cause the planar parts of each contact spring resiliently to flex angularly away from each other about the fold by which said planar parts of such contact spring are connected together.
An electrical socket terminal having an elongate stamped and formed metal socket comprising a tubular base having a forward end, and first and second elongate cantilever contact springs projecting forwardly from the forward end of the base, each contact spring comprising two planar parts defining an angle between them, and a hinge extending longitudinally of the socket and connecting the forward ends of two planar parts of the contact spring for resilient angular movement about said hinge, the planar parts of each contact spring being separate from each other between the respective hinge and the base, each of the planar parts being connected to said forward end of the base, at the rearward end of said planar part, the planar parts being resiliently angularly displaceable by an electrical pin when introduced between the contact springs from their forward ends.
An electrical socket terminal, comprising an elongate stamped and formed metal socket having walls defining a rectangular cross section, tubular, rear base, each wall having a forward end, the socket further having a pair of elongate, cantilever, contact springs projecting forwardly from the base, each contact spring comprising two planar parts each having a forward and a rear end, the planar parts of each contact spring cooperating to define a right angle between them, a hinge extending longitudinally of the socket connecting the forward ends of the two planar parts of each contact spring for resilient angular movement of said planar parts towards and away from each other about said hinge, the planar parts of each contact spring being separated from each other by a slot extending between the respective hinge and the base, and the rear end of each of said planar parts being formed integrally with the forward end of a respective one of said walls of the base, the planar parts of each contact spring being resiliently displaceable away from each other by an electrical pin when introduced between said planar parts from their forward ends.
