Structure and method for connecting terminal
View Patent ↗A terminal has a plurality of clamping portions in which surfaces facing each other serve as clamping surfaces. The plurality of clamping portions are crimped such that the respective clamping surfaces are substantially parallel to each other, thereby clamping strands configuring a fiber conductor, by the clamping surfaces. Each of the plurality of clamping portions is bent at least once in a longitudinal direction of an electric wire so as to maintain a state where the clamping surfaces are substantially parallel to each other.
1. A terminal connection structure comprising a metal terminal connected to an electric wire including a conductor having a plurality of strands,
wherein the metal terminal has a plurality of clamping portions comprising surfaces facing each other and configured to serve as clamping surfaces,
wherein the plurality of clamping portions are crimped over the plurality of strands of the conductor such that the clamping surfaces are substantially parallel to each other and the clamping surfaces clamp the plurality of strands of the conductor,
wherein each of the plurality of clamping portions has at least two bent portion in a longitudinal direction of the electric wire, and the clamping surfaces are held substantially parallel to each other, and
wherein the plurality of clamping portions include a clamping plate portion configured to clamp a first portion of the conductor onto a bottom clamping portion of the metal terminal, and a pressing plate portion configured to press onto a surface of the clamping plate portion and clamp a second portion of the conductor therebetween such that the first portion of the conductor is clamped between the clamping plate portion and the bottom clamping portion of the metal terminal, and the second portion of the conductor is folded over the clamping plate portion and clamped between the clamping plate portion and the pressing plate portion.
2. The terminal connection structure according to claim 1 , wherein each of the plurality of clamping portions has more than two bent portions in the longitudinal direction of the electric wire and is formed in a crank shape.
3. The terminal connection structure according to claim 1 , wherein the conductor includes a fiber conductor, and
the plurality of strands of the conductor are metal-plated fibers with electric conductivity.
4. The terminal connection structure according to claim 2 , wherein the conductor includes a fiber conductor, and
the plurality of strands of the conductor are metal-plated fibers with electric conductivity imparted thereto by metal plating on a surface of the metal-plated fibers.
5. The terminal connection structure according to claim 3 , wherein the metal-plated fibers comprise a polyarylate fiber.
6. The terminal connection structure according to claim 4 , wherein the metal-plated fibers comprise a polyarylate fiber.
7. The terminal connection structure according to claim 1 , wherein the plurality of clamping portions further includes a flat plate portion, and wherein the flat plate portion and the clamping plate portion are configured for clamping the conductor therebetween.
8. The terminal connection structure according to claim 7 , wherein the flat plate portion, the clamping plate portion and the pressing plate portion are substantially parallel to each other when the conductor is clamped therein.
9. The terminal connection structure according to claim 1 , wherein the plurality of clamping portions and the conductor are bent towards a same direction.
