  • Patent number: 9419400
    Abstract: The invention provides a terminal chain so that a terminal can be connected with a signal conductor only by being press-formed by dies. A rectangular piece (12) is jointed to an end part extending in the longitudinal direction of a carrier (11). The rectangular piece (12) is placed in dies (40, 50) for press-forming. A signal conductor W1 exposed at one end of a wire W is placed on the rectangular piece (12). The rectangular piece (12) is press-formed by the dies (40, 50) to enclose the signal conductor W1. A terminal (20) which is connected with the signal conductor W1 is formed. The contacting position of the carrier (11) and the terminal (20) is disconnected.

  • Patent number: 9106040
    Abstract: In the invention, an upper die (18) includes an anti-extrusion projection (17) that projects toward a signal conductor (14) placed on an upper side of a terminal forming piece (12) loaded on a lower die (19) and a die inner wall surface (18a) that situated on either side of the anti-extrusion projection (17) and that folds the terminal forming piece (12). When the terminal forming piece (12) is crimped to the signal conductor (14) by means of the upper die (18) and the lower die (19), the anti-extrusion projection (17) presses the signal conductor (14) downward, and the die inner wall surfaces (18a) fold the terminal forming piece (12) such that both ends of the terminal forming piece (12) come close to the anti-extrusion projection (17).

  • Publication number: 20130104392
    Abstract: A challenge to be met by the invention is to provide a die assembly and a crimping method that enable prevention of extrusion of a signal conductor from clearance between both ends of a terminal forming piece, which would otherwise occur when the signal conductor of an electric wire loaded on the terminal forming piece is swaged so as to be enwrapped. In the invention, an upper die (18) includes an anti-extrusion projection (17) that projects toward a signal conductor (14) placed on an upper side of a terminal forming piece (12) loaded on a lower die (19) and a die inner wall surface (18a) that situated on either side of the anti-extrusion projection (17) and that folds the terminal forming piece (12).

  • Patent number: 8414329
    Abstract: A connector for a coaxial cable which enables an end of a shield wire to be held inside a shield terminal as a housing, without generating a backlash, and can be made compact as a whole. Each of crimping barrel parts of a shield terminal is provided with a butting face which is opposed to each of flanges when the crimping barrel parts are folded at its one end, and an inclined face, at the other end at an opposite side to the butting face. The inclined face is brought into sliding contact with the inclined face of the other crimping barrel part when the crimping barrel parts are folded, and the inclined face is inclined to extend in a direction perpendicular to a direction where a pair of the crimping barrel parts are folded.

  • Patent number: 8118612
    Abstract: To provide an end-processing structure of a coaxial cable, in which a catching engagement less liable to invite damage is achieved, a high tensile strength can be obtained, and also the reliability can be enhanced. A folded braid portion 24 is formed by folding an annular projecting braid portion 23 from its proximal end portion 34 so as to superpose the folded annular projecting braid portion on one insulative sheath 31a. When the proximal end portion 34 of the annular projecting braid portion 23 is bent, a terminal catching portion 35 is formed at the folded braid portion 24.
