Description

本発明は、帯状金属板をプレス打抜き加工して製作する、コネクタの連続端子の技術分野に属する。   The present invention belongs to the technical field of continuous terminals of connectors, which are manufactured by press punching a strip-shaped metal plate.

前述のように、端子部の曲げ加工により図3(b)、(c)のように端子が形成された連続端子は保管或いは運搬のためにリールに巻き取られるが、形成され終わった端子から見れば端子ピッチPは必要以上に長く、その間隔を自由に調節することもできず、必要程度の長さの場合に較べて、1リール当りの巻き取り端子数が少なく、プレス工程でのリール替え回数が多く稼働率が低いと言う問題があるうえ、所定の端子数に対するリール数が多く、保管、運搬にスペースを多く要するという問題があった。   As described above, the continuous terminal formed with the terminal as shown in FIGS. 3B and 3C by winding the terminal portion is wound around the reel for storage or transportation. As can be seen, the terminal pitch P is longer than necessary, and the interval cannot be freely adjusted, and the number of winding terminals per reel is smaller than in the case of the required length, and the reel in the press process In addition to the problem that the number of replacements is large and the operation rate is low, the number of reels for a predetermined number of terminals is large, and there is a problem that a large space is required for storage and transportation.

本発明は、キャリアに屈曲部を設けることにより形成された端子間のピッチを短くするとともにピッチ間隔を自由に調節できるようにすることにより、上記問題点を解決することを課題とする。   An object of the present invention is to solve the above problems by shortening the pitch between terminals formed by providing a bent portion on a carrier and allowing the pitch interval to be freely adjusted.

本発明は、上記の課題を解決するために、以下の構成を有する。
本発明の第1の構成(基本構成)は、帯状キャリアの長手方向の一定間隔毎に、折り曲げ形成された端子が連結部を介してキャリアに並列につながっている連続端子において、キャリアの各端子間部分に、キャリアの長手方向と直交する方向でキャリアの厚味断面を見る方向から見て、前記端子が形成されている面側へ立ち上り長手方向へ曲って伸び再び下がる屈曲部が各曲げ部分が丸味をもって形成されていることを特徴とする連続端子である。
In order to solve the above-described problems, the present invention has the following configuration.
The first configuration (basic configuration) of the present invention is such that each terminal of the carrier is a continuous terminal in which a bent terminal is connected in parallel to the carrier via a connecting portion at regular intervals in the longitudinal direction of the belt-shaped carrier. Each bent portion has a bent portion that rises toward the surface side on which the terminal is formed, extends in the longitudinal direction, and lowers again when viewed from the direction in which the thick section of the carrier is viewed in a direction perpendicular to the longitudinal direction of the carrier. Is a continuous terminal characterized by being rounded.

本発明第2の構成は、第1の構成の屈曲部に代えて山形の屈曲部が形成されていることを特徴とする連続端子である。   The second configuration of the present invention is a continuous terminal characterized in that an angled bent portion is formed instead of the bent portion of the first configuration.

本発明第3の構成は、第1の構成又は第2の構成において、屈曲部の頂部が凹湾部を形成していることを特徴とする連続端子である。   A third configuration of the present invention is a continuous terminal characterized in that, in the first configuration or the second configuration, the top of the bent portion forms a concave bay portion.

前記第1の構成で述べたように本発明の連続端子は、キャリアの各端子間部分に、キャリアの長手方向と直交する方向でキャリアの厚味断面を見る方向から見て、前記端子が形成されている面側へ立ち上り長手方向へ曲って伸び再び下がる屈曲部が形成されているので、端子間の間隔がキャリアに屈曲部を形成しない場合に較べて屈曲部を設けた分だけ短くすることができる。   As described in the first configuration, the continuous terminal according to the present invention is formed at the portion between the terminals of the carrier as seen from the direction of viewing the thick section of the carrier in the direction perpendicular to the longitudinal direction of the carrier. Since the bent part that rises in the longitudinal direction and bends in the longitudinal direction is formed again, the distance between the terminals should be shortened by the amount of the bent part compared to the case where the bent part is not formed in the carrier. Can do.

従って、一定の長さ当りの端子の数が、屈曲部を設けない場合よりも多くなり、リールに巻き取る際の1リール当りの巻き取り端子数が多くなり、プレス工程でのリール替え回数が少なくなり、稼働率が向上し、コストダウンになる。   Accordingly, the number of terminals per fixed length is greater than when no bent portion is provided, the number of winding terminals per reel when winding on a reel is increased, and the number of reel replacements in the pressing process is increased. Reduces the operating rate and reduces costs.

更に、この屈曲部が、キャリアの長手方向と直交する方向でキャリアの厚味断面を見る方向から見て端子が形成されている面側に頂部が向くように形成されているので、屈曲部の高さが端子の高さ以下であるかぎり、リールに巻き取った場合の1層の厚さが増加することはないという利点がある。   Further, since the bent portion is formed so that the top portion faces the surface side where the terminal is formed when viewed from the direction of viewing the thick section of the carrier in the direction orthogonal to the longitudinal direction of the carrier, As long as the height is equal to or less than the height of the terminal, there is an advantage that the thickness of one layer when wound on a reel does not increase.

こうして、巻き取った後のリールの直径が大きくならずに1リール当りの巻き取り端子数が多くなることにより、所定端子数に対するリール数が少なくて済み、保管や運送の際のスペースが少なくて済むという利点がある。   Thus, since the number of winding terminals per reel is increased without increasing the diameter of the reel after winding, the number of reels with respect to the predetermined number of terminals can be reduced, and the space for storage and transportation is reduced. There is an advantage that it can be done.

また、屈曲部における各曲げ部分が丸味を持たせた曲げとなっているので、曲げ部分に弾力性がありクラックが生じにくいという利点もある。
第2の構成は屈曲部が山形になっている場合であるが、第1の構成の場合と全く同様の効果がある。
Further, since each bent portion in the bent portion is bent with roundness, there is also an advantage that the bent portion is elastic and cracks are hardly generated.
The second configuration is a case where the bent portion has a mountain shape, but has the same effect as the first configuration.

第3の構成では、屈曲部の頂部に凹湾が形成されており、上記の利点に加えてこの凹湾部の深さを加減することにより端子間のピッチ間隔を自由に調節することができるという利点がある。   In the third configuration, a concave bay is formed at the top of the bent portion, and in addition to the above advantages, the pitch interval between the terminals can be freely adjusted by adjusting the depth of the concave bay portion. There is an advantage.

本発明実施の最良の形態としては、屈曲部の断面形状が端子の高さ以下のほぼ方形になるよう形成するのが最良である。
即ち、キャリア平面から曲がり角が丸味を持つようにして立ち上り、端子の高さを越えない位置で長手方向へ同様の形状で曲がり、長手方向へ伸びた後再び下がり、キャリア平面で再び長手方向へ曲がるという形状である。
As the best mode for carrying out the present invention, it is best to form the bent portion so that the cross-sectional shape of the bent portion is substantially square with the height of the terminal or less.
That is, it rises from the carrier plane with a rounded corner, bends in the same shape in the longitudinal direction at a position that does not exceed the height of the terminal, extends in the longitudinal direction, then falls again, and bends in the longitudinal direction again at the carrier plane. It is a shape.

上記形状では曲がり箇所が4箇所あるが、いずれの曲がり箇所においても少なくとも曲がりの内側面が丸味を持った曲がりになるようにすることである。
こうすることにより曲がり部分における亀裂の発生を防止することができる。
In the above shape, there are four bends, but at any of the bends, at least the inner surface of the bend should be rounded.
By doing so, it is possible to prevent the occurrence of cracks in the bent portion.

以下、本発明の実施例を図面を参照して説明する。
図1は、本発明の第1の実施例の構造図である。(a)は平面図、(b)はキャリアの長手方向に対し直角の方向でキャリアの厚味断面を見る方向からの側面図である。
従来の連続端子(図3の(b))と異なる点は、端子1が設けられている面側へ立ち上る屈曲部3が設けられている点である。
この屈曲部3を設けたことにより、設けなかった場合の端子1のピッチ間隔が、R1、R2間の距離とR3、R4間の距離の和の長さだけ短くなる。これにより、長手方向の一定長に対する端子数が多くなり、リールに巻き取る際1リール当りの端子数が多くなり、所定の総端子数に対するリール数が少なくて済み、プレス工程でのリール替え回数や、保管や運送の際のスペースも少なくて済む。
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a structural diagram of a first embodiment of the present invention. (A) is a top view, (b) is a side view from the direction which sees the thick cross section of a carrier in the direction orthogonal to the longitudinal direction of a carrier.
The difference from the conventional continuous terminal ((b) of FIG. 3) is that a bent portion 3 rising to the surface side where the terminal 1 is provided is provided.
By providing the bent portion 3, the pitch interval of the terminals 1 when not provided is shortened by the sum of the distance between R1 and R2 and the distance between R3 and R4. This increases the number of terminals for a certain length in the longitudinal direction, increases the number of terminals per reel when winding on a reel, and reduces the number of reels relative to a predetermined total number of terminals. And there is less space for storage and transportation.

屈曲部3の高さを端子1の高さより高くならないようにすることにより、リールへ巻き取ったときの1層の厚さも変わらず、従って、巻き回数が同じであれば、巻き取り後のリール外径は従来と同じである。即ち、巻き取り後のリール外径が大きくならずに巻き取り端子数が多くなる。
また、R1〜R4で示す曲げ箇所の曲げは丸味を持った曲げとすることにより、曲げ部分での亀裂が生じないようにしている。
By making the height of the bent portion 3 not higher than the height of the terminal 1, the thickness of one layer when wound on the reel does not change. Therefore, if the number of windings is the same, the reel after winding The outer diameter is the same as before. That is, the reel outer diameter after winding does not increase, and the number of winding terminals increases.
Moreover, the bending of the bending part shown by R1-R4 is made into the bending with roundness so that the crack in a bending part may not arise.

本実施例では、屈曲部3は略方形、即ち、R1、R2間およびR3、R4間がほぼ垂直、R2、R3間がほぼ水平の場合が示されているが、このような形状に限られるものではなく、三角形、逆三角形、台形、逆台形等種々の形状であってもよい。従って、曲げ部分の曲げ角度(辺の延長線の交差角)は直角に限らず、鋭角、鈍角である場合を含むことになる。ただ、いずれの曲げ角度の場合であっても角度変化がステップ変化でない丸味を持った曲げ方とする。   In this embodiment, the bent portion 3 is substantially square, that is, between R1 and R2 and between R3 and R4 is substantially vertical, and between R2 and R3 is substantially horizontal, but is limited to such a shape. It may be various shapes such as a triangle, an inverted triangle, a trapezoid, and an inverted trapezoid. Therefore, the bending angle of the bent portion (intersection angle of the extension line of the side) is not limited to a right angle, but includes a case where the angle is an acute angle or an obtuse angle. However, in any bending angle, the bending method has a roundness in which the angle change is not a step change.

以上、第1の実施例、第2の実施例において、電線圧着部のある例が示されているが、ない場合であっても同様である。   As mentioned above, in the 1st example and the 2nd example, although an example with an electric wire crimping part is shown, it is the same even if it is not a case.

図2は、本発明の第2の実施例の構造図である。(a)は平面図、(b)は、キャリアの長手方向に対し直角の方向でキャリアの厚味断面を見る方向からの側面図である。
図1との相違点は屈曲部3の頂部が凹湾部10を形成していることである。
この凹湾部10の深さを加減することにより、端子間のピッチを更に短くする方向での調整が可能となる。
この場合であっても、各曲げ部分R1〜R5は丸味を持った曲げとすること図1の場合と同様である。
FIG. 2 is a structural diagram of the second embodiment of the present invention. (A) is a top view, (b) is a side view from the direction which sees the thick cross section of a carrier in the direction orthogonal to the longitudinal direction of a carrier.
The difference from FIG. 1 is that the top of the bent portion 3 forms a concave bay portion 10.
By adjusting the depth of the concave bay portion 10, adjustment in the direction of further shortening the pitch between the terminals becomes possible.
Even in this case, the bent portions R1 to R5 are bent with the same roundness as in the case of FIG.
