Terminal, wire harness, and electric wire with terminal
A terminal includes: a tubular box portion to receive a mating terminal; a spring portion extending in a beam shape from a front end portion of the box portion; and a pressing piece configured to restrict a bending range of the spring portion. A free end of the spring portion is inside the box portion, and the spring portion has a contact point with the mating terminal. The pressing piece is placed at a pressing position located inside the box portion and away from the contact point in the bending direction. The pressing piece is configured to restrict the bending range of the spring portion to achieve at least part of the spring portion closer to the free end than the contact point is located on the bending direction side with respect to the pressing position.
1. A terminal to be attached to an electric wire, the terminal comprising:
a tubular box portion to receive a mating terminal;
a spring portion extending in a beam shape from a front end portion of the box portion, a free end of the spring portion being inside the box portion with respect to a rear end portion of the box portion, and the spring portion having a contact point with the mating terminal; and
a pressing piece configured to restrict a bending range of the free end of the spring portion,
the spring portion being configured to elastically deform in a bending direction away from the mating terminal upon the mating terminal coming into contact with the contact point, and
the pressing piece being placed at a pressing position located inside the box portion and away from the contact point in the bending direction, the pressing piece being configured to, in the bending direction, only partly restrict the bending range of the free end of the spring portion to achieve at least part of the spring portion closer to the free end than the contact point being located on the bending direction side with respect to the pressing position.
2. The terminal according to claim 1 , wherein
the pressing piece is configured to restrict a bending range of the spring portion to achieve the free end of the spring portion is positioned on the bending direction side with respect to the pressing position.
3. The terminal according to claim 1 , further comprising:
a protruding portion extending from a side wall of the box portion toward outside of the box portion and being folded back its extending end toward inside of the box portion,
the pressing piece is provided on the extending end of the protruding portion.
4. A wire harness comprising:
a plurality of electric wires; and
the terminal according to claim 1 attached to at least one of the plurality of electric wires,
the wire harness having a bonded portion, conductor core wires of the plurality of electric wires being bonded with each other to form the bonded portion, and
the bonded portion having a bonding mark formed by ultrasonic bonding processing.
5. An electric wire with terminal comprising:
an electric wire; and
the terminal according to claim 1 attached to the electric wire,
a conductor core wire of the electric wire and the terminal being bonded to each other to form a bonded portion, and
the bonded portion having a bonding mark formed by ultrasonic bonding processing.
6. The terminal according to claim 1 ,
wherein the box portion comprises pairs of inner walls facing ones of each other and collectively surrounding the free end of the spring portion, and
wherein the free end of the spring portion is separated from each of the inner walls of the box portion.
7. The terminal according to claim 1 ,
wherein along a longitudinal direction of the terminal, at least a portion of the pressing piece is further away from the contact point than is any portion of the spring portion.
