近時、自動車、ＯＡ機器等の高性能化に伴う各種制御回路の増加等により電線 の配線箇所が多くなり、そのために電線を細径化して軽量化を図る要望が高まっ ている。この要望に答えるべく、電線導体の素導体を改良して強度アップを図り 、よって、導体総断面積を０.０５〜０.１５mm2程度まで細径化できるようにし た電線導体を本出願人から特願平１−３２５６９８号、特願平１−３２５６９９ 号、特願平１−３２５７００号等で提案している。In recent years, the number of wiring lines has increased due to the increase in various control circuits accompanying the higher performance of automobiles, office automation equipment, etc. Therefore, there is an increasing demand for reducing the diameter of electric wires to reduce their weight. To meet this demand, the applicant of the present invention has improved the strength of the wire conductor by improving the strength of the wire conductor so that the total cross-sectional area of the wire conductor can be reduced to about 0.05 to 0.15 mm 2. Japanese Patent Application No. 1-325698, Japanese Patent Application No. 1-325699, Japanese Patent Application No. 1-325700.
【０００３】 また、自動車等の配線では端子を多く使用しており、電線は図８に示すように 圧着端子と接続されている。 即ち、圧着端子１は基板部２の一端に電気接触部３を、 中央部に芯線圧着部４ を、他端に被覆圧着部５を備えており、 電線６の芯線７を芯線圧着部４に、被覆 部８を被覆圧着部５内に挿入した状態で、各圧着部４、５をかしめ圧着し、芯線 ７および被覆部８の全周を圧縮する状態で電線６と端子１との圧着接続を行って いる。In addition, many terminals are used for wiring of automobiles and the like, and the electric wires are connected to crimp terminals as shown in FIG. That is, the crimp terminal 1 is provided with the electric contact portion 3 at one end of the substrate portion 2, the core crimp portion 4 at the center portion, and the covering crimp portion 5 at the other end, and the core wire 7 of the electric wire 6 is connected to the core crimp portion 4. , With the covering portion 8 inserted into the covering crimping portion 5, the crimping portions 4 and 5 are crimped and crimped, and the wire 7 and the terminal 1 are crimped and connected while the entire circumference of the core wire 7 and the covering portion 8 is compressed. It is carried out.
【０００４】 上記端子と電線の圧着接続部分において、衝撃荷重に対する保持は、一般に、 芯線７に対する芯線圧着部４の圧着力により行っており、被覆部８に対する被覆 圧着部５での保持は横ずれ摩耗による切断防止を図る程度のものとしている。In the crimp connection portion of the above-mentioned terminal and the electric wire, the holding against the impact load is generally performed by the crimping force of the core wire crimping portion 4 with respect to the core wire 7, and the covering with the covering portion 8 is carried out by lateral displacement wear. It is only intended to prevent disconnection.
【０００５】[0005]
上記のように衝撃荷重に対して、芯線圧着部４と芯線７との圧着により保持す る場合、電線が細径電線であると、衝撃荷重に対する強度については芯線での信 頼性が低く、芯線が切断して、断線しやくい問題がある。 As described above, in the case of holding the core wire by crimping the core wire crimping portion 4 and the core wire 7 against an impact load, if the electric wire is a thin wire, the reliability of the core wire with respect to the impact load is low, There is a problem that the core wire is cut and it is easy to disconnect.
【０００６】 また、芯線７と芯線圧着部４との圧着力を増大させて耐衝撃荷重を向上させよ うとすると、金属片からなる芯線圧着部４の大きな圧着力で細径の芯線を強圧す るため、芯線の撚線素線群の撚り構成が崩れると共に素線群が圧着力によって塑 性変形して機械的性質が低下し、かつ、芯線圧着部との圧着段階で損傷が生じた り断線して電気的導通性を損ないやすい問題がある。Further, when an attempt is made to increase the crimping force between the core wire 7 and the core wire crimping portion 4 to improve the impact resistance load, the core wire crimping portion 4 made of a metal piece strongly presses the thin core wire. As a result, the twisted structure of the stranded wire element group of the core wire collapses, the wire group is plastically deformed by the crimping force, and the mechanical properties deteriorate, and damage occurs at the crimping step with the core wire crimping part. There is a problem that it is easy to break the wire and impair electrical conductivity.
【０００７】 本考案は上記した問題に鑑みてなされたもので、細径電線の端子圧着構造を、 衝撃荷重作用時に衝撃を緩和および吸収出来る構造として、芯線の切断を防止す ることを目的とするものである。The present invention has been made in view of the above problems, and it is an object of the present invention to prevent the core wire from being cut by using a terminal crimping structure for a small-diameter wire as a structure capable of absorbing and absorbing shock when a shock load is applied. To do.

上記目的を達成するため、本考案は、基板部の前端に電気接触部を有すると共 に後部に被覆圧着部を有し、被覆圧着部と電気接触部の間に芯線圧着部を有する 圧着端子に対して、後端より電線を挿入して圧着接続するものにおいて、 上記芯線圧着部と被覆圧着部とで夫々圧着保持される電線の間を撓ませた状態 で電線を圧着端子に接続し、衝撃荷重作用時に電線に作用する引張力で上記撓ん だ部分が直線状に延びて衝撃力を緩和・吸収する構成としている端子の圧着構造 を提供するものである。 In order to achieve the above object, the present invention provides a crimp terminal having an electric contact portion at a front end of a substrate portion, a cover crimp portion at a rear portion, and a core wire crimp portion between the cover crimp portion and the electric contact portion. On the other hand, in the case where the electric wire is inserted from the rear end and crimped and connected, the electric wire is connected to the crimp terminal in a state where the electric wires crimped and held by the core wire crimping portion and the covering crimping portion are bent, (EN) A crimping structure for a terminal, in which a tensile force applied to an electric wire when an impact load is applied causes the bent portion to extend linearly so as to absorb / absorb the impact force.
【０００９】 上記芯線圧着部と被覆圧着部との間の電線は、単に、両圧着部の間の電線を撓 ませた状態として両側の両圧着部で電線を圧着して撓ませることが出来る。この 場合には、圧着端子および電線自体の構造は従来のものを用いることが出来る利 点を有する。The electric wire between the core wire crimping portion and the cover crimping portion can be bent by simply crimping the electric wire between both crimping portions with the electric wire between both crimping portions being bent. In this case, the structure of the crimp terminal and the wire itself has the advantage that the conventional structure can be used.
【００１０】 また、芯線圧着部と被覆圧着部との間の基板部に、芯線圧着部と被覆圧着部と で圧着される間の電線を両圧着部より上方に浮き上げて撓ませるようにした浮き 上げ支持片を基板部より突設し、衝撃荷重作用時に電線に作用する引張力で浮き 上げ支持片を押下しながら電線が直線状に延びて衝撃力を緩和・吸収する構成と してもよい。Further, the electric wire is crimped between the core wire crimping portion and the covering crimping portion while being crimped between the core wire crimping portion and the covering crimping portion, so that the electric wire is lifted above both crimping portions and bent. Even if the lifting support piece is provided so as to project from the board, and the tensile force that acts on the wire when an impact load is applied pushes down the lifting support piece, the wire extends linearly to absorb and absorb the impact force. Good.
【００１１】 上記基板部に設ける浮き上げ支持片は、基板部の左右一側端より上方へ突出す る垂直部と、垂直部の上端より基板部の上面と所定間隔をあけて水平方向へ屈折 する水平部とからなるＬ形状の突出片からなり、この突出片の水平部で支持され た電線は、前方の芯線圧着部および後方の被覆圧着部で圧着された位置より上方 へ湾曲状に浮き上がって支持されるようにしている。この湾曲状に浮き上がって 支持されることにより生じる撓み代、即ち、最短距離の直線状に保持された場合 と比較して生じる撓み代は、衝撃荷重作用時に必要な電線の延びに相当するよう に設定している。The floating support piece provided on the substrate portion is bent in the horizontal direction at a predetermined distance from a vertical portion protruding upward from one of the left and right ends of the substrate portion and an upper surface of the substrate portion from an upper end of the vertical portion. The wire supported by the horizontal part of this protruding piece is curved above the position where it is crimped by the core wire crimping part in the front and the cover crimping part in the rear. Are being supported. The bending margin caused by being lifted up and supported by the curved shape, that is, the bending margin generated as compared with the case of being held in a straight line with the shortest distance, corresponds to the extension of the electric wire required when an impact load is applied. It is set.
【００１２】 上記浮き上げ支持片は、基板部の左右両側より向き合うように突出したＬ形状 の突出片から構成しても良く、電線を支持する浮き上げ支持片の水平部の形状を 円弧形状あるいは傾斜形状としても良い。 即ち、電線を両側の圧着部より上方に突出させて、直線状に支持した場合と比 較して所要長さだけ撓ませ、かつ、電線に衝撃荷重が作用して、電線が直線状に 延びようとする際に容易に下方に押下られて電線の直線形状の延びを許容出来る 構成としておれば良い。The floating support piece may be composed of an L-shaped protruding piece that protrudes from the left and right sides of the substrate portion so as to face each other. The shape of the horizontal portion of the floating support piece that supports the electric wire is an arc shape or an arc shape. It may have an inclined shape. That is, the wire is projected upward from the crimping parts on both sides and is bent for a required length as compared with the case where it is supported in a straight line, and an impact load acts on the wire, and the wire extends in a straight line. In such a case, the wire may be easily pushed down to allow the linear extension of the wire.

上記のように、本考案では、衝撃荷重作用時に、芯線が切断する前に、芯線圧 着部より後方の位置で撓んでいた電線が直線状に延びることが出来るため、この 延びにより瞬間的な衝撃力を緩和・吸収することができる。その際、直線状に延 びる電線は、その芯線が芯線圧着部により支持されているため、電線の被覆が被 覆圧着部よりずるずると後退しながら移動することとなる。 このように、衝撃荷重が作用した時に被覆電線部の延びで衝撃を緩和・吸収し 、芯線に作用するのを時間的にずらせることができるため、芯線が衝撃荷重によ り切断するのを有効に防止することが出来る。 As described above, in the present invention, when an impact load is applied, the electric wire that has been bent at a position rearward of the core wire pressing portion can be linearly extended before the core wire is cut. Can absorb and absorb impact force. At that time, since the core wire of the linearly extending electric wire is supported by the core wire crimping portion, if the coating of the electric wire is slippery from the covered crimping portion, the electric wire moves backward. In this way, when a shock load is applied, the extension of the covered electric wire portion absorbs and absorbs the shock, and it is possible to deviate in time the effect on the core wire. It can be effectively prevented.

以下、本考案を図面に示す実施例により詳細に説明する。 図１に示す圧着端子１０において、基板部１１の前端に電気接触部１２を突設 し、この電気接触部１２の後方に、基板部１１の左右両側より一対の突出片１３ aと１３bとを突出させてＵ字溝状の芯線圧着部１３を設けている。また、基板部 １１の後端に、左右両側より一対の突出片１４aと１４bを突出させて被覆圧着部 １４を設けている。 Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. In the crimp terminal 10 shown in FIG. 1, an electric contact portion 12 is projectingly provided on the front end of the board portion 11, and a pair of projecting pieces 13 a and 13 b is provided on the left and right sides of the board portion 11 behind the electric contact portion 12. A U-shaped groove-shaped core wire crimping portion 13 is provided so as to project. Further, at the rear end of the substrate portion 11, a pair of projecting pieces 14a and 14b are projected from the left and right sides to provide a cover crimping portion 14.
【００１５】 上記芯線圧着部１３と被覆圧着部１４の間の基板部１１に、浮き上げ支持片 １５を設けている。該浮き上げ支持片１５は基板部１１の左右一側端縁より上方 へ突出させた垂直部１５a、垂直部１５aの上端より基板部１１の上面側へ屈折さ せた水平部１５bとからなる片持ち支持された略Ｌ形状である。この浮き上げ支 持片１５の高さ(垂直部１５aの高さ)は水平部１５bの上面で押しあげる電線の高 さが前後両側の芯線圧着部１３と被覆圧着部１４で圧着される電線の高さより高 くなり、芯線圧着部１３と被覆圧着部１４との間で最短距離の直線状に支持され た場合と比較して所要量の撓みが生じる状態となるように設定している。A floating support piece 15 is provided on the substrate portion 11 between the core wire crimping portion 13 and the cover crimping portion 14. The floating support piece 15 is composed of a vertical portion 15a protruding upward from one of the left and right edges of the substrate portion 11 and a horizontal portion 15b bent from the upper end of the vertical portion 15a to the upper surface side of the substrate portion 11. It has a substantially L shape that is held and supported. The height of the lifting support piece 15 (height of the vertical portion 15a) is the height of the electric wire pushed up on the upper surface of the horizontal portion 15b of the electric wire to be crimped by the core wire crimping portion 13 and the covering crimping portion 14 on both front and rear sides. The height is higher than the height, and a required amount of bending is set as compared with the case where the core wire crimping portion 13 and the covering crimping portion 14 are supported in a straight line with the shortest distance.
【００１６】 上記圧着端子１０に対して細径電線２０を後端開口より挿入し、図２に示すよ うに、その先端に露出させた芯線２１を芯線圧着部１３に、被覆２２で被覆され た電線部分２３を被覆圧着部１４に位置させている。その際、芯線圧着部１３と 被覆圧着部１４との間では浮き上げ支持片１５が突出しているため、当該部分の 電線部分２４は上方に湾曲してた撓んだ状態となっている。 上記浮き上げ支持片１５で被覆電線部分２４がたわんだ状態で、芯線圧着部 １３と被覆圧着部１４とをかしめ圧着して、芯線２１および被覆電線部２３を圧 着端子１０に接続している。The small-diameter electric wire 20 was inserted into the crimp terminal 10 through the rear end opening, and as shown in FIG. 2, the core wire 21 exposed at the tip was covered with the coating 22 on the core wire crimping portion 13. The electric wire portion 23 is located on the covering crimp portion 14. At that time, since the floating support piece 15 projects between the core wire crimping portion 13 and the cover crimping portion 14, the electric wire portion 24 of that portion is in a bent state bent upward. With the covered electric wire portion 24 being bent by the floating support piece 15, the core wire crimping portion 13 and the covering crimping portion 14 are caulked and crimped to connect the core wire 21 and the covered electric wire portion 23 to the pressure terminal 10. ..
【００１７】 上記圧着端子１０に接続された電線２０に対して、図３に示すように、矢印で 示す後方へ電線２０を引張する衝撃荷重が作用した時、電線２０は浮き上げ支持 片１５の支持に抗して、撓んだ部分が直線状に延びて後方へ引っ張られる。その 際、浮き上げ支持片１５は垂直部１５bにより片持ち支持された状態であるため 、上面の電線２０により容易に押し下げられる。 上記浮き上げ支持片部１５の変形により、電線２０が直線状に延びた時、被覆 電線部２３の部分が被覆圧着部１４とずるずると摺接しながらが後方へ引張され る。かつ、電線２０が直線状に延びた後も更に引張力が作用すると、被覆２２を 芯線２１から剥離しながら引張する。As shown in FIG. 3, when an impact load is applied to the electric wire 20 connected to the crimp terminal 10 to pull the electric wire 20 backward as shown by an arrow, the electric wire 20 is lifted up by the lifting support piece 15. The bent portion extends linearly and is pulled rearward against the support. At that time, since the floating support piece 15 is cantilevered by the vertical portion 15b, it can be easily pushed down by the electric wire 20 on the upper surface. When the electric wire 20 extends in a straight line due to the deformation of the lifting support piece portion 15, the portion of the covered electric wire portion 23 is slidably brought into contact with the covered crimp portion 14 and pulled backward. Further, when the tensile force is further applied even after the electric wire 20 extends linearly, the coating 22 is peeled off from the core wire 21 and pulled.
【００１８】 このように、瞬間的に作用する衝撃引張力は、上記したように、浮き上げ支持 片１５の変形により、電線を延ばして衝撃力を吸収するため、芯線圧着部１３に より圧着された芯線２１には衝撃力が直接的に作用せず、あるいは作用したとし ても緩和させた後に作用するため、芯線２１の切断は効果的に抑止出来る。As described above, the impact tensile force that acts instantaneously is extended by the deformation of the lifting support piece 15 to extend the wire and absorb the impact force, so that it is crimped by the core wire crimping portion 13. Since the impact force does not act directly on the core wire 21, or even if it does, it acts after being relaxed, the cutting of the core wire 21 can be effectively suppressed.
【００１９】 上記基板部１１に形成する浮き上げ支持片１５は、上記形状に限定されず、電 線２０を芯線圧着部１３と被覆圧着部１４との間で撓せ、かつ、引張衝撃荷重が 電線に作用した時に、容易に押し下げられて変形する形状であれば良い。The floating support piece 15 formed on the substrate portion 11 is not limited to the above-described shape, and the electric wire 20 is bent between the core wire crimping portion 13 and the cover crimping portion 14, and a tensile impact load is applied. Any shape that can be easily pushed down and deformed when it acts on the electric wire may be used.
【００２０】 例えば、図４に示すように、 浮き上げ支持片１５−Iと１５−IIとを基板部 １１の左右両側より突設してもよい。 また、図５に示すように、浮き上げ支持片１５の水平部１５bを円弧形状に湾 曲させても良いし、図６に示すように、水平部１５bを傾斜させても良い。For example, as shown in FIG. 4, the floating support pieces 15-I and 15-II may be provided so as to project from both left and right sides of the substrate portion 11. Further, as shown in FIG. 5, the horizontal portion 15b of the lifting support piece 15 may be curved in an arc shape, or, as shown in FIG. 6, the horizontal portion 15b may be inclined.
【００２１】 上記した実施例はいずれも、芯線圧着部１３と被覆圧着部１４との間で電線を 撓ませるために浮き上げ支持片を圧着端子１０の基板部１１より突設したもので あるが、図７の変形例に示すように、浮き上げ支持片を突設せずに、電線の撓ん だ部分を支持せずに、単に撓わませておくだけでも良い。In each of the above-described embodiments, a floating support piece is provided so as to project from the board portion 11 of the crimp terminal 10 in order to bend the wire between the core wire crimping portion 13 and the covering crimping portion 14. As shown in the modified example of FIG. 7, it is also possible to simply bend the floating supporting piece without projecting it and without supporting the bent portion of the wire.
【００２２】 即ち、図７に示すように、芯線圧着部１３と被覆圧着部１４との間の電線２０ を、最短距離の直線状よりも距離が長くなるように撓ませた部分２５を設け、こ の撓ませた状態で上記芯線圧着部１３と被覆圧着部１４とで電線をかしめ圧着し ている。この場合、撓ませた部分２５には上記かしめ圧着時にガイド棒(図示せ ず)を挿入して撓みを確保しているが、 圧着後はガイド棒を除き撓み部分２５を 支持片等で支持していない。That is, as shown in FIG. 7, a portion 25 is provided in which the electric wire 20 between the core wire crimping portion 13 and the covering crimping portion 14 is bent so that the distance is longer than the straight line having the shortest distance, In this bent state, the core wire crimping portion 13 and the cover crimping portion 14 crimp the electric wire. In this case, a guide rod (not shown) is inserted into the bent portion 25 at the time of crimping and crimping to secure the bending. However, after crimping, the guide portion is removed and the bending portion 25 is supported by a supporting piece or the like. Not not.
【００２３】 上記変形例において、電線２０に対して引張方向に衝撃荷重が作用した時、電 線２０は被覆２２が被覆圧着部１４に対して摺接して剥れながら、撓ませた部分 ２５が直線状に延びて、瞬間的に衝撃荷重を緩和・吸収する。よって、電線２０ の芯線２１へ衝撃荷重が作用するのを時間的に遅らせると共に衝撃力を緩和・吸 収し、芯線２１の切断を防止できる。In the above modification, when an impact load is applied to the electric wire 20 in the pulling direction, the electric wire 20 has a portion 25 that is bent while the coating 22 slides off the coating crimp portion 14 and peels off. Stretches straight to absorb and absorb shock load instantaneously. Therefore, the impact load acting on the core wire 21 of the electric wire 20 can be delayed with time, and the impact force can be alleviated and absorbed to prevent the core wire 21 from being cut.

以上の説明より明らかなように、本考案に係わる細径電線の圧着構造では、端 子の芯線圧着部と被覆圧着部の間に浮き上げ支持片を設け、引張衝撃荷重が作用 した時に、瞬間的に電線が浮き上げ支持片を押下して変形させながら直線状に延 びて衝撃力を緩和・吸収できる構造としているため、あるいは、上記浮き上げ支 持片を設けずに、単に芯線圧着部と被覆圧着部の間の電線を撓ませて、衝撃荷重 が作用した時に撓み部分が直線状に延びて衝撃力を緩和・吸収できる構造として いるため、芯線圧着部で圧着された細径の芯線に衝撃力が直接的に作用するのを 防止あるいは緩和でき、芯線の切断を抑止できる。 As is clear from the above description, in the crimping structure for a small-diameter wire according to the present invention, a floating support piece is provided between the core crimping portion of the terminal and the cover crimping portion, and when a tensile impact load is applied, the moment The wire has a structure in which the lifting support piece is pressed down and deformed to extend in a straight line while relaxing and absorbing the impact force, or the above-mentioned lifting support piece is not provided and the core wire crimping part is simply used. By bending the wire between the cover and the crimping section, the flexible section extends linearly when an impact load is applied to absorb and absorb the impact force.Thus, the thin core wire crimped by the core crimping section It is possible to prevent or mitigate the impact force directly acting on, and to prevent the cutting of the core wire.
【００２５】 また、上記のように、端子の基板部に浮き上げ支持片を設ける極めて簡単な構 造であるため、コストアップにならずに実施でき、実用的価値の大なるものであ る。Further, as described above, since the floating support piece is provided on the substrate portion of the terminal, the structure can be carried out without increasing the cost and is of great practical value.
