Description

本発明は、自動車のワイヤハーネス等に用いられる電線の端末同士を電気的接続するために利用される電線の接続部材と、その接続部材を用いた電線の接続方法とに関する。 The present invention relates to an electric wire connecting member used for electrically connecting terminals of electric wires used for an automobile wire harness and the like, and an electric wire connecting method using the connecting member.

自動車のワイヤハーネス等を製造する際に、一本又は複数本の電線の端末同士を電気的に接続する必要が生じた場合、それぞれの電線の端末の被覆を除去して導体を露出させ、互いの導体同士を撚り合わる等して結合した後、絶縁テープを巻回するという方法がよく行われている。しかし、この接続方法では、作業が面倒な上、引っ張り等の外力に対して固定力が弱く、作業ごとにばらつきも生じやすいため、信頼性が十分でない。
そこで、作業性や信頼性を高めるために、特許文献１，２に開示の如く、結合した導体部分に絶縁性キャップを被せたり、スリットを入れた絶縁チューブをの字状にラップさせて溶着したりする対策が考案されている。 When it is necessary to electrically connect the terminals of one or a plurality of electric wires when manufacturing a wire harness of an automobile, the conductors are exposed by removing the covering of the terminals of each electric wire. A method of winding an insulating tape after the conductors are joined by twisting each other is often performed. However, in this connection method, the work is troublesome and the fixing force is weak against an external force such as pulling, and variations are likely to occur from work to work. Therefore, the reliability is not sufficient.
Therefore, in order to improve workability and reliability, as disclosed in Patent Documents 1 and 2, an insulating cap is put on the joined conductor part, or an insulating tube with a slit is wrapped in a letter shape and welded. Measures have been devised.

特開平１１−８９０５６号公報JP 11-89056 A 特開２００５−１２９３２５号公報JP 2005-129325 A 特開２００７−１５７６９３号公報JP 2007-157893 A

しかし、特許文献１，２のように絶縁性キャップを用いた場合、キャップに固定した電線が互いに異なる方向へ引っ張られると、絶縁性キャップが外れる方向へ力が加わるため、絶縁性キャップが外れたり、電線同士が離れたりするおそれが生じる。
また、特許文献３の絶縁チューブを用いた場合、絶縁チューブのラップ部分の径が太くなるため、自動車への組付けの際等に絶縁チューブが周囲に引っ掛かりやすくなり、外力によって絶縁チューブが電線に沿ってずれを起こしてしまうおそれがある。 However, when an insulating cap is used as in Patent Documents 1 and 2, if the electric wires fixed to the cap are pulled in different directions, a force is applied in the direction in which the insulating cap is removed. There is a risk that the wires will be separated.
In addition, when the insulating tube of Patent Document 3 is used, the diameter of the wrap portion of the insulating tube is increased, so that the insulating tube is easily caught around when it is assembled to an automobile, etc., and the insulating tube becomes an electric wire by external force. There is a risk of causing a shift.

そこで、本発明は、電線同士の接続に係る作業性が良好であるのは勿論、外力による電線の外れ等を好適に防止でき、電気的接続の信頼性にも優れた電線の接続部材及び接続方法を提供することを目的としたものである。 Therefore, the present invention is not only good in workability related to the connection between the electric wires, but can suitably prevent the disconnection of the electric wires due to an external force, and the electric wire connection member and connection excellent in electrical connection reliability. It is intended to provide a method.

Moreover, since the disconnection of the electric wire due to an external force can be suitably prevented, the reliability of electrical connection is excellent.
And the pulling-out direction of the electric wire between two locking grooves becomes mutually opposite, and an electric wire becomes difficult to pull out from an electric wire holding part. In addition, the direction in which the wire is pulled out in each locking groove intersects with the opening direction from the closed position of the cover, so that the force to remove the wire is not applied to the wire holding part and each locking groove at the same time.

以下、本発明の実施の形態を図面に基づいて説明する。
図１は、電線の接続部材の一例を示す斜視図で、この接続部材１は、帯板状の本体２を備えると共に、本体２の長手方向の側縁中央にカバー３を結合して一体成形される合成樹脂製となっている。本体２には、長手方向の中央に電線の端末を保持する端末保持部４が形成されると共に、その端末保持部４を挟んで長手方向の前後に、本体２上で相反方向に配設される電線を保持する一対の電線保持部５，５がそれぞれ形成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an example of an electric wire connecting member. The connecting member 1 includes a band plate-shaped main body 2 and is integrally formed by connecting a cover 3 to the center of a side edge in the longitudinal direction of the main body 2. Made of synthetic resin. The main body 2 is formed with a terminal holding portion 4 that holds the end of the electric wire in the center in the longitudinal direction, and is disposed in the opposite direction on the main body 2 before and after the terminal holding portion 4 in the longitudinal direction. A pair of electric wire holding portions 5 and 5 for holding electric wires are formed.

まず、端末保持部４は、図２〜４にも示すように、長手方向に収容溝６を凹設した横断面コ字状で、端末の導体同士が結合された一対の電線の結合部分を収容可能となっている。また、端末保持部４におけるカバー３と反対側の長手側縁中央には、下向きの返し状となる係止突起７が形成され、その係止突起７の前後に、長手側縁に沿った一対の保護壁８，８が上向きに形成されている。この保護壁８により、カバー３を閉じた際にカバー３が保護されて、外力による偶発的な外れのおそれが低減される。 First, as shown in FIGS. 2 to 4, the terminal holding portion 4 has a U-shaped cross section in which a receiving groove 6 is recessed in the longitudinal direction, and a connecting portion of a pair of electric wires in which conductors of the terminal are connected to each other. It can be accommodated. In addition, a locking projection 7 having a downward turning shape is formed at the center of the longitudinal side edge opposite to the cover 3 in the terminal holding portion 4, and a pair along the longitudinal side edge before and after the locking projection 7. The protective walls 8, 8 are formed upward. The protective wall 8 protects the cover 3 when the cover 3 is closed, and reduces the risk of accidental detachment due to external force.

カバー３は、端末保持部４と同様の横断面コ字状で形成され、薄肉のヒンジ部９，９により、端末保持部４の上方を覆って収容溝６を塞ぐ閉位置と、端末保持部４の上方から退避して収容溝６を開放する開位置との間で回転可能に蝶着されている。但し、カバー３における長手方向の前後端は、開放された出入口１０，１０となっている。
また、カバー３におけるヒンジ部９，９と反対側の側縁中央には、閉位置で端末保持部４の係止突起７が係止する係止孔１２を備えた弾性片１１が突設されている。 The cover 3 is formed in a U-shaped cross-section similar to the terminal holding part 4, and has a closed position where the upper part of the terminal holding part 4 is covered by the thin hinge parts 9 and 9 to close the receiving groove 6, and the terminal holding part It is hinged so that it can rotate between the open position which retracts | saves from 4 and opens the accommodation groove | channel 6. FIG. However, the front and rear ends of the cover 3 in the longitudinal direction are opened doors 10 and 10.
Further, an elastic piece 11 provided with a locking hole 12 that locks the locking projection 7 of the terminal holding portion 4 in the closed position protrudes from the center of the side edge of the cover 3 opposite to the hinge portions 9 and 9. ing.

そして、各電線保持部５には、端末保持部４寄りに位置する第１係止溝１３Ａと、本体２の端部寄りに位置する第２係止溝１３Ｂとがそれぞれ形成されている。なお、電線保持部５は前後対称の形状であるため一方のみについて説明する。 Each electric wire holding portion 5 is formed with a first locking groove 13A positioned near the terminal holding portion 4 and a second locking groove 13B positioned near the end of the main body 2. In addition, since the electric wire holding part 5 is a symmetrical shape, only one side will be described.

第１、第２係止溝１３Ａ，１３Ｂは、側方となる長手端縁から直交状に切り込まれる導入部１４と、その導入部１４の終端へ直角に連結され、本体２の幅方向中心付近で本体２の端部へ向けて長手方向に形成される係止部１５とからなるＬ字状に形成されている。但し、第１、第２係止溝１３Ａ，１３Ｂ間では、導入部１４が切り込まれる長手端縁は互いに逆となっている。また、係止部１５の位置も本体２の幅方向中心から互いに逆側へ僅かにずれた位置となっている。さらに、導入部１４を形成する前後の内面と、係止部１５を形成する前後の内面とは、第１係止溝１３Ａでは、端末保持部４へ近づくに従って下り傾斜する傾斜面となり、第２係止溝１３Ｂでは、端末保持部４へ近づくに従って上り傾斜する傾斜面となっている。 The first and second locking grooves 13 A and 13 B are connected at right angles to the end portion of the introduction portion 14 that is cut orthogonally from the longitudinal end edge that is the side, and the width direction center of the main body 2. It is formed in an L shape comprising a locking portion 15 formed in the longitudinal direction toward the end of the main body 2 in the vicinity. However, between the first and second locking grooves 13A and 13B, the longitudinal edges into which the introduction portion 14 is cut are opposite to each other. The position of the locking portion 15 is also slightly shifted from the center in the width direction of the main body 2 to the opposite sides. Furthermore, the inner surface before and after forming the introduction portion 14 and the inner surface before and after forming the locking portion 15 are inclined surfaces that incline downward toward the terminal holding portion 4 in the first locking groove 13A. The locking groove 13 B is an inclined surface that is inclined upward as it approaches the terminal holding portion 4.

１６は、各電線保持部５の上下面において第１、第２係止溝１３Ａ，１３Ｂの間で本体２の幅方向に突設された突条で、本体２の上面では、各電線保持部５における端末保持部４寄りの位置にもそれぞれ突設されている。
また、端末保持部４と電線保持部５との上面は突条１６を除いて同一平面となっているが、ここでは端末保持部４の厚みが電線保持部５の厚みよりも大きく形成されているため、端末保持部４の下面が電線保持部５の下面よりも下方へ突出している。 16 is a protrusion protruding in the width direction of the main body 2 between the first and second locking grooves 13A and 13B on the upper and lower surfaces of each electric wire holding portion 5, and on the upper surface of the main body 2, each electric wire holding portion 5 are also provided in a projecting position near the terminal holding unit 4.
Moreover, although the upper surface of the terminal holding part 4 and the electric wire holding part 5 is the same plane except for the protrusion 16, the thickness of the terminal holding part 4 is formed larger than the thickness of the electric wire holding part 5. Therefore, the lower surface of the terminal holding part 4 protrudes below the lower surface of the electric wire holding part 5.

以上の如く構成された接続部材１を用いた電線の接続方法を説明する。
まず、端末同士を接続するそれぞれの電線の端末の絶縁被覆を除去し、内部の導体を露出させて、導体同士を撚り合わせる等して直線状に結合する。このとき必要に応じて結合部分を絶縁テープ等で巻回してもよい。 An electric wire connection method using the connection member 1 configured as described above will be described.
First, the insulation coating of the terminal of each electric wire which connects terminals is removed, the internal conductor is exposed, and the conductors are joined together in a straight line, for example. At this time, the coupling portion may be wound with an insulating tape or the like as necessary.

次に、導体同士を結合した電線２０，２０を、図５に示すように、カバー３を開位置とした接続部材１の上面にセットし、導体同士の結合部分を端末保持部４の収容溝６に収容する。このとき、結合部分がテープ巻き等によって径が太くなっていても、収容溝６によって位置決めは可能である。
結合部分のセット後、カバー３を同図矢印のように閉位置へ回転させると、弾性片１１の係止孔１２が係止突起７に係止してカバー３が閉位置で固定される。これにより両電線２０，２０の結合部分が覆われ、両電線２０，２０はカバー３両端の出入口１０，１０からそれぞれ相反方向へ引き出される格好で保持される。 Next, as illustrated in FIG. 5, the electric wires 20 and 20 in which the conductors are coupled to each other are set on the upper surface of the connection member 1 with the cover 3 in the open position, and the coupling portion between the conductors is accommodated in the receiving groove of the terminal holding portion 4. 6 to accommodate. At this time, even if the connecting portion is thickened by tape winding or the like, positioning can be performed by the receiving groove 6.
After the coupling portion is set, when the cover 3 is rotated to the closed position as indicated by an arrow in the figure, the locking hole 12 of the elastic piece 11 is locked to the locking projection 7 and the cover 3 is fixed at the closed position. Thereby, the joint part of both the electric wires 20 and 20 is covered, and both the electric wires 20 and 20 are hold | maintained by the shape pulled out from the entrances 10 and 10 of the cover 3 both ends in the opposite direction, respectively.

そして、各電線２０を、それぞれ対応する電線保持部５において、まず第１係止溝１３Ａの導入部１４から引き入れてその終端まで導くことで係止部１５を上から下へ貫通させた後、今度は第２係止溝１３Ｂの導入部１４から引き入れてその終端まで導くことで係止部１５を下から上へ貫通させて本体２の端部側へ引き出す。すると、各電線２０は、図５に示すように電線保持部５の第１、第２係止溝１３Ａ，１３Ｂで係止され、外から引張力が加わっても第２係止溝１３Ｂ若しくは第１係止溝１３Ａの位置でとどまり、端末保持部４まで伝わることはない。 Then, after each of the electric wires 20 is inserted into the first holding groove 13A from the introduction portion 14 in the corresponding electric wire holding portion 5 and guided to the end thereof, the locking portion 15 is penetrated from top to bottom, This time, it pulls in from the introduction part 14 of the 2nd latching groove 13B, and guides it to the end, so that the latching part 15 is penetrated from the bottom to the top and pulled out to the end part side of the main body 2. Then, each electric wire 20 is locked by the first and second locking grooves 13A and 13B of the wire holding portion 5 as shown in FIG. 5, and even if a tensile force is applied from the outside, the second locking groove 13B or the second locking groove 13B It stays at the position of the one locking groove 13 A and does not reach the terminal holding portion 4.

なお、この状態で電線２０，２０の電気的接続及び保持は完了しているが、必要に応じて接続部材１へ電線２０，２０ごと絶縁テープを巻回してさらなる一体化を図ってもよい。ここでは端末保持部４が電線保持部５よりも厚みが大きくなっているので、絶縁テープを巻回した際に長手方向にずれるおそれがなく、しっかりと固定できる。
また、接続する電線２０の径が太くて各係止溝１３Ａ，１３Ｂに係止できない場合は、各電線保持部５において電線５を絶縁テープで巻回すればよい、この場合は突条１６が電線２０に押圧して滑り止め作用を生じさせるため、電線保持部５と電線２０との一体化は図られる。 In addition, although the electrical connection and holding of the electric wires 20 and 20 are completed in this state, further integration may be achieved by winding an insulating tape together with the electric wires 20 and 20 around the connecting member 1 as necessary. Here, since the terminal holding part 4 is thicker than the electric wire holding part 5, there is no possibility of shifting in the longitudinal direction when the insulating tape is wound, and the terminal holding part 4 can be firmly fixed.
Further, when the diameter of the electric wire 20 to be connected is large and cannot be locked in the locking grooves 13A and 13B, the electric wires 5 may be wound around each electric wire holding portion 5 with an insulating tape. Since the electric wire 20 is pressed to cause an anti-slip action, the electric wire holding part 5 and the electric wire 20 are integrated.

このように、上記形態の接続部材１及び接続方法によれば、導体同士を接続した電線２０，２０を端末保持部４にセットしてカバー３を閉じ、各電線２０を電線保持部５の第１、第２係止溝１３Ａ，１３Ｂへ係止させれば、電線２０，２０の電気的接続とその保持とが可能となる。従って、電線２０，２０同士の接続に係る作業性が良好となる。また、外力による電線２０，２０の外れ等を好適に防止できるため、電気的接続の信頼性にも優れたものとなる。 Thus, according to the connection member 1 and the connection method of the said form, the electric wires 20 and 20 which connected the conductors are set to the terminal holding | maintenance part 4, the cover 3 is closed, and each electric wire 20 is the 1st of the electric wire holding | maintenance part 5. If it latches to the 1st, 2nd latching grooves 13A and 13B, the electrical connection of the electric wires 20 and 20 and its holding | maintenance will be attained. Therefore, workability related to the connection between the electric wires 20 and 20 is improved. Moreover, since the disconnection of the electric wires 20 and 20 due to an external force can be suitably prevented, the reliability of electrical connection is excellent.

特にここでは、係止溝を、側方からの導入側が互いに逆となる一対の第１、第２係止溝１３Ａ，１３Ｂとすると共に、カバー３の開閉方向を、側方からの導入方向と交差するように設定しているので、２つの係止溝１３Ａ，１３Ｂ間での電線２０の抜け方向が互いに逆となり、電線保持部５から電線２０が抜けにくくなる。また、各係止溝１３Ａ，１３Ｂにおける電線２０の抜け方向（本体２の幅方向）と、カバー３の閉位置からの開放方向（上下方向）とが交差して、電線保持部５と各係止溝１３Ａ，１３Ｂとに電線２０を外す力が同時に加わることがないため、電線２０は一層外れにくくなる。 In particular, here, the locking groove is a pair of first and second locking grooves 13A and 13B whose introduction sides from the side are opposite to each other, and the opening and closing direction of the cover 3 is the introduction direction from the side. Since they are set so as to cross each other, the pulling directions of the electric wires 20 between the two locking grooves 13 A and 13 B are opposite to each other, and the electric wires 20 are not easily pulled out from the electric wire holding part 5. Further, the direction in which the electric wire 20 is pulled out (the width direction of the main body 2) in each of the locking grooves 13A and 13B intersects with the opening direction (vertical direction) from the closed position of the cover 3, so Since the force which removes the electric wire 20 is not simultaneously applied to the stop grooves 13A and 13B, the electric wire 20 is more difficult to come off.

また、各係止溝１３Ａ，１３Ｂの内面を、電線２０の配設方向に沿って傾斜させているので、各係止溝１３Ａ，１３Ｂに対する電線２０の係止がしやすくなって作業性が向上する上、係止後の電線２０が電線保持部５に沿って引き回され、大きく突出しないので、省スペースとなって周囲との接触による損傷や外れの可能性も低減される。さらに、各係止溝１３Ａ，１３Ｂから電線２０へ加わるストレスも小さくて済むため、電線２０の耐久性の向上も期待できる。
加えて、各係止溝１３Ａ，１３Ｂを、側方から形成される導入部１４と、その導入部１４の終端から配設方向に形成される係止部１５とからなるＬ字状としたことで、電線２０の外れ防止に好適な形状となる。 Further, since the inner surfaces of the respective locking grooves 13A and 13B are inclined along the direction in which the electric wires 20 are arranged, the electric wires 20 can be easily locked to the respective locking grooves 13A and 13B, and workability is improved. In addition, since the locked electric wire 20 is routed along the electric wire holding portion 5 and does not protrude greatly, the space is saved, and the possibility of damage or disconnection due to contact with the surroundings is reduced. Furthermore, since the stress applied to the electric wire 20 from each of the locking grooves 13A and 13B can be reduced, an improvement in the durability of the electric wire 20 can be expected.
In addition, each of the locking grooves 13A and 13B has an L shape including an introduction portion 14 formed from the side and a locking portion 15 formed in the arrangement direction from the terminal end of the introduction portion 14. Thus, the shape is suitable for preventing the electric wire 20 from coming off.

なお、端末保持部や電線保持部の形態は適宜変更可能で、例えば端末保持部ではカバーの位置を逆にしたり、端末保持部とカバーとの横断面形状を半円にしたり、カバーを幅方向に一対設けて幅方向に開閉させたり等してもよい。また、カバーと端末保持部との係止構造も、係止突起と弾性片とを互いの逆側に設けたりしても差し支えない。さらにはカバーを端末保持部と別体に設けることも可能である。
一方、電線保持部も、係止部を短くしたりできる。係止溝の内面における傾斜の省略も可能である。また、導入部の角度は、上記形態のようにカバーの開方向に対して直交するのが望ましいが、直交でなくとも交差状であれば電線の外れ防止効果は得られるため、適宜角度を変更してもよい。
In addition, the form of the terminal holding part and the electric wire holding part can be changed as appropriate, for example, the terminal holding part has the cover in the reverse position, the cross-sectional shape of the terminal holding part and the cover is a semicircle, or the cover in the width direction. A pair may be provided to open and close in the width direction. In addition, the locking structure between the cover and the terminal holding portion may be such that the locking protrusion and the elastic piece are provided on the opposite sides. Furthermore, the cover can be provided separately from the terminal holding portion.
On the other hand, the wire holding part can also shorten the locking part. It is possible to omit the inclination on the inner surface of the locking groove. In addition, it is desirable that the angle of the introduction portion is orthogonal to the opening direction of the cover as in the above embodiment, but if it is not orthogonal but an intersection, the effect of preventing the wire from coming off can be obtained, so the angle can be changed as appropriate. May be.

その他、突条の数や位置を変更したり、端末保持部を電線保持部よりも幅方向の寸法を大きくしたり、端末保持部と電線保持部との間を薄肉にして可撓性を持たせたりすることも考えられる。
そして、電線は相反方向で一本ずつで限定するものではなく、一方側又は双方側が複数の電線であっても、端末保持部及び電線保持部での保持が可能であれば、本発明は採用可能である。なお、係止溝が複数の場合は複数の電線を異なる係止溝に係止させてもよい。 In addition, the number and position of the ridges can be changed, the terminal holding part can be made wider in the width direction than the wire holding part, or the space between the terminal holding part and the wire holding part can be made thin and flexible. It is also possible to make it.
And the electric wire is not limited to one by one in the opposite direction, and even if one side or both sides are plural electric wires, the present invention is adopted as long as it can be held by the terminal holding portion and the electric wire holding portion.
