子がコスト高になるという問題があった。By the way, in the above-mentioned conventional technology, in order to ensure sufficient contact between the pressure contact terminal 2 and the electric wire 1, the diameter d of the circular conductor 1a (Fig. 7) and the width G of the pressure contact groove 21 must be adjusted after pressure contact. In order to maintain an appropriate contact pressure between the conductor and the pressure welding groove, it is necessary to set a < b and within a range that does not cause breakage of the conductor or plastic deformation of the pressure welding blade. Conductor 1a
If the diameter of the terminal changes, a special pressure contact terminal with a corresponding width of pressure contact groove is required, which increases the number of types of pressure contact terminals, complicates their usage, and increases the cost of the pressure contact terminals. There was a problem.

Electric wires for insulation displacement terminals consisting of multiple types are characterized by having a conductor with the same rectangular size and an oval cross section and an insulating coating layer provided around the conductor, and the short diameter side of the conductor is pressed against the terminal fitting. This provides a contact structure that makes contact with the pressure welding blade in the groove.
以下に本発明の一実施例を図面を用いて説明する。 An embodiment of the present invention will be described below with reference to the drawings.
第１図から第４図は本発明の実施例を示す図で、これら

設けられている。この圧接溝２１の幅をａとする。The short axis dimension of the conductor 11 having an oval cross section is assumed to be b, and the long axis dimension is C. 2 is a pressure contact terminal, 21 is a pressure contact groove in which a pressure contact blade 23 is formed, and 22 is a tapered blade portion for guiding the electric wire 1. Two pressure contact grooves 21 and 21 are provided before and after one pressure contact terminal 2. ing. The width of this press-contact groove 21 is assumed to be a.
第２図は本発明の断面長円形の導体１１を有する電線１
の断面を示す。断面長円形の導体１１は、短径寸法すを
一定にしつつ、長径寸法Ｃを種々に変化させることによ
りサイズ変更を行って形成される複数より成る。FIG. 2 shows an electric wire 1 having a conductor 11 having an oval cross section according to the present invention.
A cross section of is shown. The conductor 11 having an oval cross section is formed by changing the size by keeping the short axis constant and varying the long axis C.
例えば、短径寸法ｂ ＝ ０．９ ｍｍとした場合、ｃ
＝ ０．９ ｔｒａで
断面積０．５儒相当の電線となる。For example, when the short axis dimension b = 0.9 mm, c
= 0.9 tra, resulting in a wire with a cross-sectional area equivalent to 0.5 tra.
ｃ ＝ １．２鵬で 断面積０．８５−相当の電線となる。c = 1.2 peng The wire has a cross-sectional area of 0.85.
ｃ ＝ １．９ ｍａで 断面積１．２５ ｍｍ相当の電線となる。c = 1.9 ma The wire has a cross-sectional area of 1.25 mm.
第３図（ａ） 、 （ｂ）に示すように、圧接溝２１の
幅ａは、短径寸法ｂ ＝ ０．９ ｍｍに対して最適な
幅に形成されているので、一種類の圧接端子２で種々の
断面積の電線ｌを圧接接続できることとなる。As shown in FIGS. 3(a) and 3(b), the width a of the pressure welding groove 21 is formed to the optimum width for the minor axis dimension b = 0.9 mm, so that it can be used as a single type of pressure contact terminal. In step 2, electric wires l having various cross-sectional areas can be connected by pressure contact.
圧接端子２と電線１の接続は次のように行う。The pressure contact terminal 2 and the electric wire 1 are connected as follows.
まず、第４図（ａ）から（ｂ）に示すようにテーパー状
刃部２２に電線を置き、電線ｌをゆっくりと、たとえば
、矢符号Ｒ方向に回して圧接溝２１に対する挿入姿勢を
決める。この状態で、電線１を圧接溝２工に圧入すると

とき、第４図（Ｃ）に示すように電線１は圧接溝２１内
に進入し、電線１と圧接端子２が接続される。First, as shown in FIGS. 4(a) to 4(b), an electric wire is placed on the tapered blade portion 22, and the electric wire 1 is slowly rotated, for example, in the direction of the arrow mark R to determine the insertion attitude into the pressure contact groove 21. In this state, when the electric wire 1 is press-fitted into the pressure welding groove 2, the insulation coating 12 is cut by the tapered blade 22, and when the short diameter of the conductor 11, which has an oval cross section, coincides with the pressure welding groove 21, as shown in FIG. As shown in C), the electric wire 1 enters the press-contact groove 21, and the electric wire 1 and the press-contact terminal 2 are connected.
この場合、圧接方向が外部から明確に分かれば、作業は

向を知ることができる。In this case, the work will be easier if the direction of pressure welding can be clearly seen from the outside. For example, if the thickness of the insulating coating layer 12 is made the same in all directions, the outer shape of the electric wire 1 will also have an oval cross section, and the direction of pressure contact will be easily recognized even from the outside. On the other hand, the direction of pressure welding can also be known by forming the outer shape of the electric wire 1 into a circular shape and instead adding a mark such as a minute groove or rib at a position corresponding to the major axis or minor axis of the conductor 11, which has an oval cross section. .
第３図（ａ）は断面長円形の導体１１が単線の場合の電
線ｌと圧接端子２の圧接状態で、第３図（ｂ）は同じく
撚線の場合の圧接状態を示す。FIG. 3(a) shows a state of pressure contact between the electric wire 1 and the pressure contact terminal 2 when the conductor 11 having an oval cross section is a single wire, and FIG. 3(b) shows a state of pressure contact when the conductor 11 having an oval cross section is a stranded wire.
次に第５図（ａ）から（Ｃ）によって、断面長円形の導

素線１１“から通常の円形断面を有する従来通りの導体
１１’を成形する。As shown in FIG. 5(a), a conventional conductor 11' having a normal circular cross section is formed from a wire 11'' by an extrusion molding machine 3.

に形成される。As shown in FIG. 5(b), this conductor 11' is flattened by being sandwiched between a pair of rollers 4, 4 rotating in the direction of the arrow, to obtain a conductor 11 having an oval cross section. At this time, the short axis dimension of the conductor 11 having an oval cross section is formed to have the same dimension for a group of electric wires, that is, electric wires of a plurality of sizes having different long axis dimensions.
次に第５図（Ｃ）に示すように、上記の断面長円形の導

断面長円形の導体１１を有する電線１ができあがる。Next, as shown in FIG. 5(C), the conductor 11 having an oval cross section is fed to the insulator extruder 5. At this time, by installing an insulator extruder 5 immediately after the rollers 4, 4,
The direction of the major axis or minor axis of the conductor 11 having an oval cross section is kept constant. Inside the insulator extruder 5, there is a heated and melted insulation coating material 12', and a pressure P is applied to cover the conductor 11 having an oval cross section to form an insulation coating 12.
An electric wire 1 having a conductor 11 having an oval cross section is completed.
このようにして形成された各サイズの電線１は、短径寸

法で統一しておくとよい。Since the electric wires 1 of each size thus formed have the same short axis dimension, they can be press-connected to one type of press-contact terminal. It is preferable to divide the electric wires into groups according to the size of the cross-sectional area of the conductor, and to unify the short axis dimension for each group.

ａ′を付して断面長円形の導体１１の姿勢を表示する。The cross-sectional shape of the insulating coating 12 can be freely set depending on the shape of the outlet 51 of the extruder. That is, it is not limited to the case where the conductor 11 has an oval cross section as shown in FIG. 6(a), but also the insulating coating 12' has a circular cross section as shown in FIG. 6Cb). In this case, there may be grooves, ribs, etc. on the outer surface of the insulation coating 12'.
The orientation of the conductor 11 having an oval cross section is indicated by a'.
なお、導体１１が撚り線であっても、上記の方法に準じ
