  • the technology disclosed in this specification relates to a male terminal.
  • a male terminal described in JP-A-2015-82453 (the following Patent Document 1) is known.
  • This male terminal has a pin-shaped insertion portion that is inserted into the box-shaped portion of the female terminal, and a wire crimping portion that is crimped to the core wire exposed by peeling off the sheath of the wire.
  • the female terminal to which the male terminal is connected has a pair of elastic pieces provided at the front end portion of the terminal and a wire crimping portion provided at the terminal rear end portion and crimped to the electric wire.
  • the male terminal disclosed in the present specification is a male terminal that can be fitted to a female terminal including at least a pair of elastic contact pieces, has a pin shape, and is fitted with the female terminal when the female terminal is fitted.
  • the protrusion may be configured to contact the elastic contact piece when fitted with the female terminal. According to such a configuration, the contact area between the male terminal and the female terminal when fitted is increased, and therefore the contact resistance between the male terminal and the female terminal can be further reduced.
  • the number of the protrusions may be the same as the number of the elastic contact pieces, and one protrusion may be housed between the side edges of the pair of adjacent elastic contact pieces.
  • the protrusion part of a male terminal will be accommodated between all the adjacent elastic contact pieces of a female terminal. Thereby, the load applied to the elastic contact piece when the protrusion hits the elastic contact piece by twisting the male terminal is distributed to each elastic contact piece. Therefore, the load applied to one elastic contact piece of the female terminal due to the twisting of the male terminal can be reduced.
  • the male terminal can be prevented from being twisted.
  • FIG. CC The front view which shows the state before the fitting of the male terminal and female terminal in embodiment Right side view in FIG. CC sectional view in FIG.
  • the figure which displayed only the female terminal in FIG. The figure which displayed only the male terminal in FIG.
  • the female terminal 20 is obtained by bending a metal plate material such as copper or copper alloy punched into a predetermined shape. Further, the entire surface of the female terminal 20 is plated with tin or the like. As shown in FIG. 1, the female terminal 20 includes an elastic contact piece 21 and a wire crimping portion 22.
  • each elastic contact piece 21 of the female terminal 20 is arranged at equal intervals in the circumferential direction.
  • Each elastic contact piece 21 is paired with the opposing elastic contact piece 21.
  • the inner region surrounded by each elastic contact piece 21 is a cavity 23 as shown in FIG.
  • a terminal contact portion 11 of the male terminal 10 described later is inserted into the hollow portion 23.
  • each elastic contact piece 21 inclines slightly toward radial inside. Thereby, the terminal contact portion 11 of the male terminal 10 is elastically pressed against the elastic contact piece 21 when the male terminal 10 and the female terminal 20 are fitted. Further, the distal end portion 26 of the elastic contact piece 21 is slightly bent outward in the radial direction so that a terminal contact portion 11 of the male terminal 10 described later can be easily inserted.
  • the male terminal 10 is formed by using a round bar made of metal such as copper or copper alloy as a raw material, and forging or cutting the round bar. Further, the entire surface of the male terminal 10 is plated with tin or the like. As shown in FIG. 1, the male terminal 10 includes a terminal contact portion 11, a wire crimping portion 13, and a plurality of protrusions 12 that protrude outward from the outer peripheral surface of the terminal contact portion 11.
  • the terminal contact portion 11 of the male terminal 10 is processed into a pin shape extending in the fitting direction with the female terminal 20. Furthermore, the some projection part 12 is formed by cutting the outer peripheral surface.
  • the inner diameter R ⁇ b> 3 of the terminal contact portion 11 is processed to be larger than the minimum diameter R ⁇ b> 1 between the inner surfaces of the pair of elastic contact pieces 21 and smaller than the inner diameter R ⁇ b> 2 of the inner surfaces of the pair of elastic contact pieces 21.
  • the outer diameter R4 of the pair of protrusions 12 is processed to be larger than the inner diameter R3 of the terminal contact portion 11.
  • protrusions 12 are arranged at equal intervals in the circumferential direction.
  • the number of protrusions 12 is the same as the number of elastic contact pieces 21.
  • the protrusion 12 is a protrusion that fits in a space 25 between the side edges 24 of a pair of adjacent elastic contact pieces 21 as shown in FIG. 4 when the male terminal 10 and the female terminal 20 described later are fitted.
  • the side edge 14 of the part 12 is processed so as to contact the side edge 24 of the elastic contact piece 21.
  • the electric wire crimping portion 13 of the male terminal 10 is crimped to an electric wire (not shown). Thereby, the male terminal 10 and the electric wire are electrically connected.
  • the protrusion 12 of the male terminal 10 is placed in the space 25 between the side edges 24 of the pair of adjacent elastic contact pieces 21 of the female terminal 20. It is in the form of entering. Therefore, for example, even if the male terminal 10 tries to twist by applying vibration from the outside to an electric wire (not shown) attached to the electric wire crimping portion 13 of the male terminal 10, the protruding portion 12 is formed between the adjacent elastic contact pieces 21. It will hit the side edge 24. Thereby, twisting of the male terminal 10 can be prevented.
  • the terminal contact portion 11 of the male terminal 10 is elastically pressed by the elastic contact piece 21 of the female terminal 20 as shown in FIG. As a result, the male terminal 10 and the female terminal 20 come into contact with each other and are electrically connected.
  • the side edge 14 of the protrusion 12 of the male terminal 10 is in contact with the side edge 24 of the adjacent elastic contact piece 21 of the female terminal 20. Therefore, the contact area between the male terminal 10 and the female terminal 20 increases. Thereby, the contact resistance between the male terminal 10 and the female terminal 20 can be reduced.
  • one protrusion 12 of the male terminal 10 is stored in each space 25 of the female terminal 20.
  • each protrusion 12 of the male terminal 10 contacts the side edge 24 of each elastic contact piece 21 of the female terminal 20. Therefore, the load applied to the elastic contact piece 21 when the protrusion 12 hits the elastic contact piece 21 by twisting of the male terminal 10 is distributed to each elastic contact piece 21. Thereby, the load concerning one elastic contact piece 21 by the twist of the male terminal 10 can be reduced.
  • the male terminal 10 when the male terminal 10 and the female terminal 20 are fitted, the male terminal 10 is placed in the space 25 between the side edges 24 of the pair of elastic contact pieces 21 of the female terminal 20.
  • the protruding portion 12 enters. Then, even if the male terminal 10 is twisted, the protrusion 12 of the male terminal 10 abuts the side edge 24 of the elastic contact piece 21 of the female terminal 20, so that the male terminal 10 can be prevented from being twisted.
  • the protrusion 12 contacts the side edge 24 of the adjacent elastic contact piece 21 when the male terminal 10 and the female terminal 20 are fitted, so that the male terminal 10 and the female terminal 20 are in contact with each other when fitted. Therefore, the contact resistance between the male terminal 10 and the female terminal 20 can be further reduced.
  • the protrusion 12 of the male terminal 10 is accommodated between all the adjacent elastic contact pieces 21 of the female terminal 20.
  • the load applied to the elastic contact piece 21 when the projection 12 hits the elastic contact piece 21 by twisting of the male terminal 10 is distributed to each elastic contact piece 21. Therefore, the load applied to one elastic contact piece 21 of the female terminal 20 due to the twisting of the male terminal 10 can be reduced.
