In order to achieve such an object, the terminal fitting of the present invention includes a terminal box into which a mating tab is inserted, an elastic piece extending from one side wall of the terminal box into the terminal box, and the one side wall. A tab receiving portion that is formed on the other side wall of the terminal box facing each other and sandwiches the mating tab inserted into the terminal box with the elastic piece, and the tab receiving portion includes the other side wall around the tab receiving portion. It is characterized by being formed into a shape that bulges toward the one side wall side by being compressed from one side wall side to be thin.
Moreover, this invention is formed by compressing the said other side wall facing the convex part with which the said elastic piece clamps the other party tab from the said one side wall side, and making the said tab receiving part thin. It is characterized by being.
Further, the manufacturing method of the terminal fitting of the present invention includes a tab receiving portion that sandwiches a mating tab inserted into the terminal box with a convex portion of an elastic piece extending from one side wall of the terminal box into the terminal box. A method of manufacturing a terminal fitting comprising the tab receiving portion by compressing and thinning a periphery of a region facing the convex portion on the other side wall of the terminal box facing the one side wall from the one side wall side. Including the step of forming.
本発明によれば、端子箱の他側壁におけるタブ受部の形成領域の周囲を、他側壁と向かい合う端子箱の一側壁側から圧縮して肉薄にしてタブ受部を形成することから、端子箱を低背化して端子金具を小型化できる。 According to the present invention, the tab receiving portion is formed by compressing the periphery of the tab receiving portion forming region on the other side wall of the terminal box from one side wall side of the terminal box facing the other side wall so as to be thin. The terminal bracket can be downsized by lowering the height.
以下、図面を参照して、本発明の最良の形態を説明する。
図1は、本実施形態の端子金具が備える端子箱1を拡大して示す断面図である。図2は、端子箱1が備えるタブ受部3の形成方法を説明する図である。
Hereinafter, the best mode of the present invention will be described with reference to the drawings.
FIG. 1 is an enlarged cross-sectional view showing a terminal box 1 provided in the terminal fitting of the present embodiment. FIG. 2 is a diagram illustrating a method for forming the
端子金具は、銅等の金属製の板材を折り曲げて組み上げられており、相手側タブと接続される図1に示す端子箱1と、電線の被覆の端末を圧着するためのインシュレーションバレル(不図示)と、電線の被覆から剥き出された芯線の端末を圧着するためのワイヤバレル(不図示)とを備える。 The terminal metal fitting is assembled by bending a metal plate material such as copper, and an insulation barrel (not used) for crimping the terminal box 1 shown in FIG. 1 connected to the mating tab and the end of the wire coating. And a wire barrel (not shown) for crimping the end of the core wire stripped from the coating of the electric wire.
端子箱1は、前後両面を開口する箱形状に組み上げられており、前面の開口を相手側タブの挿入口としている。端子箱1の上壁1aには、上壁1aと隣り合う側壁1cから延びた一対の巻付片1dが、外側から巻き付けられている。巻付片1dは、上壁1aの前端部及び後端部を、それぞれ外側から覆っている。
The terminal box 1 is assembled in a box shape that opens both front and rear sides, and the opening on the front is used as the insertion opening for the mating tab. A pair of
端子箱1は、上壁1aに弾性片2を、下壁1bにタブ受部3をそれぞれ備えている。弾性片2は、挿入口を構成する下壁1bの前縁から後方に屈曲して延びており、先端部にはインデント2aを備えている。タブ受部3は、上壁1aの内面を端子箱1の内側に膨出させた台状を呈している。インデント2a及びタブ受部3は、相手側タブを端子箱1内で確実に挟持するためのものである。挿入口から端子箱1に挿入された相手側タブは、弾性片2のインデント2aとタブ受部3とで挟持される。
The terminal box 1 includes an
端子金具の製造方法の一例を説明する。まず、端子金具を構成する板材の弾性片2となる箇所にインデント2aを形成し、下壁1bとなる箇所を圧縮してタブ受部3を形成する。タブ受部3は、図2(a)に模式的に示す板材(上壁1a)におけるタブ受部3の形成領域の周囲を、図2(b)に矢印Aで示すように、下壁1b側(図2では下側)から圧縮して肉薄にすることで形成されている。その後、図1に示すように、上壁1a,下壁1b,側壁1cで弾性片2を囲むように板材を折り曲げて、側壁1cの前端部及び後端部から側方に延びた巻付片1dを、上壁1aの前端部及び後端部に外側から巻き付けて、端子箱1を組み上げる。これに伴い、インシュレーションバレ(不図示)及びワイヤバレル(不図示)も同じ板材から組み上げられる。
An example of the manufacturing method of a terminal metal fitting is demonstrated. First, the
例えば、図3に示すように、上壁1aを端子箱1の外側(上側)から打ち出して、端子箱1の内側(下側)に湾曲させた形状にタブ受部30を形成する場合には、上壁1aの高さは、上壁1aを形成する板材の厚さTに、タブ受部3が端子箱1内に湾曲した分の高さH11を加えた高さH1となる。これに対し、図2を用いて上述したように、上壁1aを端子箱1の内側(下側)から圧縮して、タブ受部3の形成領域の周囲の上壁1aを肉薄にし、端子箱1の内側にタブ受部3を膨出させる場合には、上壁1aの高さH2は、上壁1aを形成する板材の厚さTと等しくなる。つまり、高さH2は、タブ受部3の端子箱1内に湾曲したタブ受部3の高さH11だけ、高さH1よりも低くなる。このため、端子箱1の高さをその分低く抑え、端子金具を小型化できる。
For example, as shown in FIG. 3, when the
以上説明したように、本実施形態によれば、端子箱1の上壁1aにおけるタブ受部3の形成領域の周囲を、下壁1b側から圧縮して肉薄にしてタブ受部3を形成することから、端子箱1を低背化して端子金具を小型化できる。
As described above, according to the present embodiment, the
また、本実施形態によれば、板材を圧縮して周囲を肉薄することでタブ受部3が形成されていることから、小型の端子金具でも所望の形状のタブ受部3を容易に加工することができる。
Moreover, according to this embodiment, since the
なお、タブ受部3の形状及び形成位置は、端子箱1内に挿入された相手側タブを、弾性片2とで挟持できるのであれば任意であり、例えば、上壁1aにおけるインデント2aと対向する箇所のみに形成されていてもよい。また、端子金具の製造方法は、上壁1aを構成する板材におけるタブ受部3の形成領域の周囲を、下壁1b側から圧縮して肉薄にすることで、タブ受部3を形成する工程を含むのであれば任意である。
