本発明は、絶縁電線を電気的に接続するためのはんだ不
要のコネクタに関するもので、特に高密度実装に好適な
小形コネクタに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a solder-free connector for electrically connecting insulated wires, and particularly to a small connector suitable for high-density packaging.
２つのＵ溝部によって隔てられた３本の腕部な備え、上

クタが、特公昭５４−２４１１３号公報にて周知である
。これは、中央の腕部が両方のＵ溝部に対して共用して
いるため、コネクタ端子の実装密度向上に寄与している
。An electric wire connector was developed by Tokuko Showa in 1999, which has three arms separated by two U-grooves, and has electric wires press-fitted into the U-grooves for mechanical and electrical connection between the electric wires and the connector terminals. It is well known from the publication No. 54-24113. This is because the central arm portion is shared by both U-groove portions, contributing to an improvement in the mounting density of the connector terminals.
このようなコネクタにおいて１１寺に凸己慮し／、ｃげ
ればならないことは、中央腕部の剛性である。The most important thing to consider in such a connector is the rigidity of the central arm.
即ち、一方のＵ溝部に電線を圧入した後に、他方のＵ溝

、中央腕部に剛性を持たせておかなければ、他方のＵ溝
部への電線の圧入に大きな操作力を必要とするばかりか
、撓み量如何によっては時としてその圧入が不可能とな
る場合がある。That is, it is often the case that a wire is press-fitted into one U-groove and then the wire is press-fitted into the other U-groove. The U-groove spacing of the oil force becomes narrower. For this reason, unless the central arm is made rigid, not only will it require a large amount of operating force to press the wire into the other U-groove, but it may also be impossible to press it depending on the amount of deflection. It may happen.

び電線の高密度実装の大きな弊害となっていた。This increase in the rigidity of the central arm was achieved by
In Japanese Patent No. 4115, the problem is solved by making the width of the central JII'i1 part larger than that of both arm parts. However, such an increase in the width of the central lung portion leads to an increase in the width of the entire terminal, which has been a major problem in high-density mounting of terminals and electric wires on the connector housing.
本発明の目的は、中央腕部の幅を両側腕部の幅より小さ
く又は同等となしたにもかかわらず剛性を備え、高密度
実装をより向上させたはんだ不要の電線コネクタを提供
することにある。An object of the present invention is to provide a solder-free electric wire connector that has rigidity even though the width of the central arm is smaller than or equal to the width of both side arms, and further improves high-density mounting. be.

とを特徴とする。In the present invention, the width of the central arm portion is formed to be equal to or narrower than the width of both side arm portions, and the central arm portion is provided with a protrusion processing portion to increase its rigidity. , is characterized in that the width of the other U-groove portion is prevented from narrowing.
以下図面に示した実施例によって本発明の詳細な説明す

The six arms extend in parallel, and their bases are connected as one body.

の１／２位に押し出されている。An opening 5 of the U groove 5 is provided at the center of the central arm 5.
An elongated bead b is extruded into a predetermined shape from a toward the base. Here, the width of the central arm portion 3 is a,
If the width of both arm portions 4 is b, then 3 due to the dimensional relationship a≦b.
The arm of the book is formed by punching, and the height h of the beat b is the thickness t of the book.
It has been pushed out to 1/2th place.

易に理解できる。FIG. 2 shows the state in which the lifting electric wire 7 is press-fitted without a beat in the central arm 3, and FIG. 3 shows the state in which there is a beat b. As can be seen from the figure, the central arm 6 The amount of deflection is very different between the two parts, and in the case of Fig. 2, both the central arm part 3 and the side arm part 40 are deflected, which makes the press-fitting work difficult when press-fitting the electric wire into the U-groove part 5 on one side. The wire holding force after press-fitting changes depending on whether the wire is connected on one side or on both sides, and this is not a desirable connection. On the other hand, in the case of FIG. 6 according to the present invention, it is easy to understand that the side arm part 4 is bent more than the central arm part 3, and the above-mentioned drawbacks are eliminated even when both sides are connected.

れた。As an application example of the present invention, the connector plate thickness t is O15,
In a connector terminal made of a flat plate of beryllium copper, the widths a and b of the center arm and side arms are 1.3 mm, the width of the U groove 5 is 0.3 mm, and the beat height is 0.27 km. An experimental result was obtained in which the rigidity of the part 3 is 1.47 times stronger than that of the side arm part 4.

る。As explained in detail above, according to the present invention, the rigidity of the central arm can be increased without increasing the width of the central arm, so a compact, high-density mounting connector can be realized, and the wire holding force can be sufficiently improved. The obtained connector has great industrial value as a connector oriented toward small size and high-density packaging in recent years.
