Definitions

  • the present invention relates to an electric terminal having a coated crimping portion for crimping and fixing a coated electric wire.
  • Patent Document 1 describes a press-fitting blade that press-fits a coated electric wire and electrically conducts with the core wire of the electric wire, and a coated crimping portion (insulation barrel) that holds the coated electric wire by crimping behind the press-fitting blade.
  • the electrical terminals provided with the above are disclosed.
  • the coated crimping portion is a coated crimping portion having a size suitable for the outer diameter dimension of the large-diameter coated electric wire. Then, at the time of crimping, the width of the coated crimping portion is crushed so as to be compatible with a small-diameter coated electric wire. By doing so, it is possible to crimp a small-diameter coated electric wire to a coated crimping portion having a size suitable for the large-diameter coated electric wire, and hold the coated electric wire with a predetermined holding force.
  • the coated crimping portion suitable for the outer diameter of the large-diameter coated electric wire
  • a play margin of the coated electric wire occurs in the coated crimping portion, and the coated electric wire floats up in the coated crimping portion. It may be crimped as it is. Then, even after crimping, a gap remains between the crimped coated electric wire and the bottom of the coated crimped portion, and there is a possibility that a predetermined holding force cannot be obtained.
  • an object of the present invention is to provide an electric terminal provided with a coated crimping portion suitable for crimping a plurality of types of coated electric wires having different external dimensions.
  • the electrical terminal of the present invention that achieves the above object is An electric terminal provided with a coated crimping portion that receives the coated portion of the coated electric wire and fixes it by crimping.
  • the coating crimping part At the bottom A pair of side parts that rise from both sides in the width direction of the bottom and receive the covered wire from above between both sides, Each of the pair of sides has a cantilever shape that extends upward and closer to each other from the lower fixed end, and is oriented away from each other by the coated wires received between the pair of sides from above. It is characterized by having a pair of spring portions that once bend and receive the covered electric wire and press the covered electric wire toward the bottom portion.
  • the electric terminal of the present invention has the above-mentioned pair of spring portions. Therefore, even if a small-diameter coated electric wire is received by the coated crimping portion, the coated electric wire is pressed toward the bottom. Therefore, it is possible to prevent a gap from being formed between the bottom portion and the covered electric wire after crimping, and the coated electric wire can be held with a predetermined holding force.
  • the pair of spring portions have a shape that extends upward and toward each other from the lower fixed end, and further extends upward and away from each other.
  • the coated electric wire received by the coated crimping portion is attracted between the pair of spring portions. Therefore, the risk that the coated electric wire received by the coated crimping portion does not enter between the pair of spring portions and the spring portion is crushed by the coated electric wire is avoided.
  • an electric terminal having a coated crimping portion suitable for crimping a plurality of types of coated electric wires having different external dimensions is realized.
  • FIG. 1 is a side view (A) of an electric terminal as an embodiment of the present invention, and an enlarged view (B) of a cross section along arrows XX shown in FIG. 1 (A). The cross section of the covered electric wire also appears in FIG. 1 (B).
  • the electric terminal 10 includes a contact portion 20, a core wire crimping portion (wire barrel) 30, and a covering crimping portion (insulation barrel) 40.
  • the contact portion 20 is a portion that makes electrical contact with a mating contact (not shown).
  • the core wire crimping portion 30 is a portion where the core wire 62 exposed by removing the insulating coating 61 of the coated electric wire 60 is crimped.
  • the coated crimping portion 40 is a portion of the coated electric wire 60 where the core wire 62 is covered with the insulating coating 61 and is crimped.
  • the coating crimping portion 40 has a bottom portion 41 and a pair of side portions 42.
  • the pair of side portions 42 rise from both sides of the bottom portion 41 in the width direction.
  • the coated crimping portion 40 receives the coated electric wire 60 from above between the side portions 42.
  • the covering crimping portion 40 is provided with a pair of spring portions 50.
  • Each of the pair of side portions 42 of the pair of spring portions 50 is cut and raised and extends upward from the lower fixed end 51 in a direction approaching each other. Further, these pair of spring portions 50 have a shape extending toward the free end 52 in a direction further upward and away from each other.
  • These pair of spring portions 50 are temporarily bent away from each other by the coated electric wires 60 received between the pair of side portions 42 from above and are received between each other.
  • the upper portion of the spring portion 50 has a shape extending upward and in a direction away from each other. Therefore, the covered electric wire 60 received between the pair of side portions 42 is easily attracted between the pair of spring portions 50.
  • These pair of spring portions 50 receive the coated electric wire 60 and press it toward the bottom portion 41. Then, the covered electric wire 60 is crimped while being pressed toward the bottom portion 41. By doing so, the coated electric wire 60 is crimped without forming a gap between the coated electric wire 60 and the bottom portion 41, and the coated electric wire 60 is held with a predetermined holding force.
  • the pair of side portions 42 have a shape symmetrical with respect to the vertical plane extending in the extending direction of the covered electric wire 60.
  • the present invention can also be applied to an electric terminal having a pair of side portions formed at different positions in the extending direction of the coated electric wire 60 as shown in Patent Document 1 described above.
  • the electric terminal 10 provided with the core wire crimping portion 30 has been taken up and described.
  • the present invention can be applied to an electric terminal provided with a pressure welding blade as in Patent Document 1 described above.
  • the present invention does not ask the shape of the contact portion 20, and includes, for example, a rod-shaped male contact portion. May be good.
  • Electric terminal 40 Covered crimping part 41 Bottom part 42 Side part 50 Spring part 51 Fixed end 52 Free end 60 Covered electric wire
