Description

本発明は、二本の電線どうしを接続通電させるために使用する電線中継コネクタに関するものである。殊に、通信用ケーブルのように微小で微細な弱電線どうしの通電に適した構造とした電線中継コネクタに関するものである。   The present invention relates to a wire relay connector used for connecting and energizing two wires. In particular, the present invention relates to a wire relay connector having a structure suitable for energization between minute and minute weak wires such as communication cables.

従来から、このような電線どうしを接続通電させるための電線中継コネクタは周知であり、多種多様の形状のものが既に製造され使用されている。また、通信用ケーブルのように微小で微細な弱電線どうしの通電に使用するコネクタも既に知られている。   Conventionally, a wire relay connector for connecting and energizing such wires is well known, and a variety of shapes have already been manufactured and used. A connector used to energize minute and weak weak wires such as communication cables is already known.

更には、通信用ケーブルのように微小で微細な弱電線どうしを接続するためのコネクタや、ケーブルの被覆を剥離することなく所定幅に形成した圧接用溝に被覆線を圧入して通電する圧接通電方式も知られている(特許文献1参照)。   Furthermore, a connector for connecting minute and minute weak wires such as a communication cable, and a pressure welding in which a coated wire is press-fitted into a pressure welding groove formed in a predetermined width without peeling off the cable coating. An energization method is also known (see Patent Document 1).

他方、二つのコネクタを左右と上下を互いに逆向きとして嵌合接続することができるように形成したコネクタについても公知になっている(特許文献2参照)。   On the other hand, a connector formed so that two connectors can be fitted and connected with the left and right sides and the top and bottom opposite to each other is also known (see Patent Document 2).

特開2005−149935号公報JP 2005-149935 A 実開平3−127780号公報Japanese Utility Model Publication No. 3-127780

前者の特許文献1には、圧接方式のジョイントコネクタが示され、その構造として、複数本の被覆電線を並列配置し、所定幅の圧接用溝を備えた複数の圧接端子にそれぞれ圧入して通電する圧接通電構造が示されている。しかしながら、通電接続を行う接続端子部の構造が、挿入側の雄形端子とこの雄形端子を受け入れる雌形端子という互いに形状の異なる嵌合構造とされ、それ故に、これらの接続端子部を覆う第1ハウジングと第2ハウジングの構造も互いに内外嵌め込み式の大小異形構造とされており、製造に当たって、コネクタもハウジングも雌雄個別の金型を必要とし、雌雄別々の組み立てを必要とし、雌雄一組をセットとして販売しなければならない点で不都合な構造となっている。   The former Patent Document 1 shows a pressure-joint joint connector, which has a structure in which a plurality of covered electric wires are arranged in parallel and are press-fitted into a plurality of pressure-contact terminals each having a predetermined-width pressure-contact groove. A pressure contact energizing structure is shown. However, the structure of the connection terminal portion for conducting the energization connection is a fitting structure having different shapes of the male terminal on the insertion side and the female terminal for receiving the male terminal, and therefore covers these connection terminal portions. The structure of the first housing and the second housing is also a large and small deformed structure that fits inside and outside, and in manufacturing, the connector and the housing require separate male and female molds, and separate male and female assembly is required. It has an inconvenient structure in that it must be sold as a set.

また、後者の特許文献2には接続器が示され、ここには、二つの接続器を互いに上下・左右逆向きにして接続可能な構造とすることが示されている。しかしながら、ここに記載の接続器にあっても、通電接続を行う接続部材の構造を、端子部と刃受ばねを備えたものとし、この刃受ばねの構造を、割溝によって上下に二分され、上部刃受ばねには、摺動刃保持部材に連結されたスライド釦の操作によって出退する摺動刃が摺動可能に保持され、下部刃受ばねには、相手方の摺動刃が差し込まれて電気的接続が達成されるようにした刃受けばね構造としてあり、即ち、上部の摺動刃が挿入側の雄形端子とされ、下部の刃受けばねが雄形端子を受け入れる雌形端子とされ、これら異形の摺動刃と刃受けばねとが摺動刃保持部材スライド操作によって通電接続する構造としたものである。また、ここに示された接続器には、前記接続部材とは別に、係合部がケースから突出した部分に設けられているロック兼ガイド部材が、スライド釦に設けられた係止片と係合して抜け止めされる構造としたものである。それ故、全体として部品点数が多く構造が複雑で、製造や組み立てが容易ではなく、高コストにならざるを得ないという課題を有するものとなっている。   Further, the latter patent document 2 shows a connector, which shows a structure in which two connectors can be connected to each other upside down and horizontally. However, even in the connector described here, the structure of the connection member that performs energization connection is assumed to be provided with a terminal portion and a blade receiving spring, and the structure of this blade receiving spring is divided into two parts by a split groove. The upper blade receiving spring is slidably held by a sliding blade that is moved back and forth by operating a slide button connected to the sliding blade holding member, and the other blade is inserted into the lower blade receiving spring. The blade receiving spring structure is configured so that electrical connection is achieved, that is, the upper sliding blade is the male terminal on the insertion side, and the lower blade receiving spring is the female terminal that receives the male terminal. In this structure, the odd-shaped sliding blade and the blade receiving spring are electrically connected by sliding operation of the sliding blade holding member. Further, in the connector shown here, in addition to the connection member, a lock / guide member provided at a portion where the engaging portion protrudes from the case is engaged with a locking piece provided on the slide button. It has a structure that prevents them from coming off together. Therefore, as a whole, the number of parts is large, the structure is complicated, the manufacture and assembly are not easy, and there is a problem that the cost must be high.

そこで、本発明は、このような従来公知のコネクタが有していた上記の各課題を解決することができる全く新しい思想に基づいて開発されたコネクタであって、通電接続を行う金属コンタクト本体を一枚の良導体金属板で形成した単一体とし、該コンタクト本体と被覆電線との接続をワンタッチ接続が可能なものとし、このコンタクト本体を覆う絶縁樹脂ハウジングも簡単なコネクタ覆い体とし、その先端側の構造を左右と上下を逆向きにして嵌合接続することができる形状として、二つのコネクタどうしを左右と上下を逆向きにして嵌合接続することができ、これら二つのコネクタどうしを電気的に接続させると同時に抜け止め作用をも完了させることができる構造とした電線中継コネクタを、全体的に簡易な構造で、製造並びに組み立てが容易で、低コストで生産することができるようにした電線中継コネクタをここに提供するものである。   Therefore, the present invention is a connector developed on the basis of a completely new idea that can solve the above-mentioned problems that such conventionally known connectors have, and has a metal contact body that performs energization connection.

本発明にいうコンタクト本体1を形成する良導体金属板の素材は、例えば、りん青銅のような銅系の素材が好ましいが、アルミ合金系の素材であっても使用することができる。また、ハウジングを形成する絶縁樹脂素材としては、例えば、ポリカーボネートのようなポリエステル系の樹脂が耐衝撃性・機械的強度に優れている点で好ましいが、絶縁性に優れている樹脂であればよく、特に限定する意図はない。   The material of the good conductor metal plate forming the contact body 1 according to the present invention is preferably a copper-based material such as phosphor bronze, but may be an aluminum alloy-based material. In addition, as the insulating resin material forming the housing, for example, a polyester-based resin such as polycarbonate is preferable in terms of excellent impact resistance and mechanical strength, but any resin having excellent insulating properties may be used. There is no particular limitation.

以下本発明の実施例について図面に基づいて説明する。本発明にいう電線中継コネクタは、全体を一枚のりん青銅製の金属板で成形加工したコンタクト本体1と、これを内挿してその外周部の全体を覆うポリカーボネート製のハウジング2とによって構成してある。そこで、先ず、コンタクト本体1の実施例から図1乃至図10を用いてその構造を説明する。   Embodiments of the present invention will be described below with reference to the drawings. The wire relay connector according to the present invention is composed of a contact body 1 formed entirely by a single phosphor bronze metal plate, and a polycarbonate housing 2 that inserts the contact body 1 and covers the entire outer periphery thereof. It is. First, the structure of the contact body 1 will be described with reference to FIGS. 1 to 10.

該コンタクト本体1は、図1〜3に示した長手方向後端側(図2に記載の左側)部分Lを、図4の左側面図及び図7のC−C断面図のように、上部開口のコの字形に形成し、後記図17に示したように、被覆電線3を圧入して絶縁被覆32を剥離させることにより、被覆内の電線31と接触させて通電させるようにした電気的圧接用通電溝11を、図4,7のように、上縁部から下方に向けて切り込み形成してある前後二枚の通電壁11a,11aを、底壁を立ち上げて形成してある。   The contact main body 1 has a longitudinal rear end side (left side in FIG. 2) portion L shown in FIGS. 1 to 3 as shown in the left side view of FIG. 4 and the CC sectional view of FIG. As shown in FIG. 17 to be described later, the coated electric wire 3 is press-fitted and the insulating coating 32 is peeled off to contact the electric wire 31 in the coating to energize it. As shown in FIGS. 4 and 7, two current-carrying walls 11a and 11a in which the pressure-contacting current-carrying groove 11 is cut downward from the upper edge portion are formed by raising the bottom wall.

続く、長手方向中間部分Mは、その後半部分を図5のA−A断面図のように断面□の字形に形成し、その前方部分を図6のB−B断面図のように断面Uの字形に形成して、その対向壁を平行壁14,14としてある。更にその先端側部分Nは、図1の正面図のように下半壁を切除して上半壁のみを残した形状として前方に向けてほぼ平行に突出させた二枚の突出壁15,15からなるコンタクト部13を形成してある。また、前記断面□の字形に形成した部分の上壁12aには、後述するハウジング2の契合段部22と契合する抜け止め突起12を、後方上向きに立ち上がらせて形成してある。   Next, the longitudinal intermediate portion M is formed in the shape of a square □ as shown in the AA cross section of FIG. 5, and the front portion of the cross section U is shown in the BB cross sectional view of FIG. The opposite walls are formed as parallel walls 14, 14. Further, the tip end portion N is composed of two projecting walls 15 and 15 projecting substantially parallel toward the front as a shape in which only the upper half wall is left by cutting the lower half wall as shown in the front view of FIG. A contact portion 13 is formed. Further, a retaining protrusion 12 that engages with an engagement step portion 22 of the housing 2, which will be described later, is formed on the upper wall 12a of the portion formed in the shape of the square □ so as to rise rearward and upward.

また、前記二枚の突出壁15,15は、次に図11を用いて説明するコネクタどうしのコンタクト時に、これら二枚の突出壁15,15の外面が前記平行壁14,14の内面と相互に弾性的に接触して通電する間隔に形成してある。この接触通電をより確実に行わせるために、該実施例のコネクタにあっては、同突出壁15,15には、平行壁14,14の内面と面接触させるための小突起16,16をそれぞれ外面に向けて突出形成させてある。   The two projecting walls 15 and 15 are arranged so that the outer surfaces of the two projecting walls 15 and 15 are mutually in contact with the inner surfaces of the parallel walls 14 and 14 when the connectors are in contact with each other as will be described with reference to FIG. It is formed in the interval which contacts with electricity and energizes. In order to perform this contact energization more reliably, in the connector of this embodiment, the projecting walls 15, 15 are provided with small protrusions 16, 16 for making surface contact with the inner surfaces of the parallel walls 14, 14. Each of them protrudes toward the outer surface.

このような構造としたコンタクト本体1どうしの接触通電は、言うまでもなくハウジング2内に内挿された状態で、雌雄同体構造とした二つのハウジング2,2どうしを図16に斜視図で示したように、左右と上下を逆向きとして相互に差し込み嵌合させることによって行うようにしたものである。   Needless to say, the contact energization between the contact main bodies 1 having such a structure is inserted in the housing 2, and the two housings 2, 2 having a hermaphroditic structure are shown in a perspective view in FIG. This is done by inserting and fitting the left and right and up and down in opposite directions.

このコンタクト本体1どうしの連結状態を説明するため、図11の上段・中段・下段に平面図を上側に、正面図を下側にして経時的に示した。先ず、上段の図のように、互いに離れた二つのコンタクト本体1,1どうしを挿入方向に移動させる。続いて中段の図のように、先端のコンタクト部13どうしが正面視で上下に位置する状態で、その最先端部が断面∪の字形とした平行壁14,14の位置まで移動し、更に進んで下段の図のように、先端のコンタクト部13が互いに相手方の平行壁14,14内に進入し、これら両部の対向面どうしが、即ち、コンタクト部13を構成する突出壁15,15の外側面と、平行壁14,14の内側面とが弾性的に接触して通電可能な状態となる。該実施例に示したコンタクト部13を構成する突出壁15,15には、それぞれ外面側に向かって突出する小突起16,16を形成してあるので、平行壁14,14の内側面とはこれらの小突起16,16が面接触して通電可能状態となるようにしてある。   In order to explain the connection state of the contact bodies 1, the plan view is shown in the upper, middle, and lower stages of FIG. First, as shown in the upper drawing, the two contact bodies 1, 1 that are separated from each other are moved in the insertion direction. Subsequently, as shown in the middle figure, with the contact parts 13 at the front ends positioned vertically in front view, the most advanced part moves to the position of the parallel walls 14 and 14 having a cross-sectional shape of a cross-section and further advances. Then, as shown in the lower figure, the contact portion 13 at the front end enters the parallel walls 14, 14 of the other party, and the opposing surfaces of these two portions, that is, the protruding walls 15, 15 constituting the contact portion 13, respectively. The outer side surface and the inner side surfaces of the parallel walls 14 and 14 are in elastic contact with each other and can be energized. Since the projecting walls 15 and 15 constituting the contact portion 13 shown in the embodiment are formed with small projections 16 and 16 projecting toward the outer surface side, respectively, the inner surfaces of the parallel walls 14 and 14 are defined as These small protrusions 16 and 16 are brought into surface contact with each other so that energization is possible.

次に、このような構造としたコンタクト本体1を絶縁状態に内包させるハウジング2について説明する。このハウジング2の形成素材は絶縁性を有する樹脂素材であれば、特に限定するものではないが、該実施例に示したハウジング2にあっては、ポリカーボネート樹脂素材を用いて成形してある。   Next, the housing 2 that encloses the contact body 1 having such a structure in an insulated state will be described. The material for forming the housing 2 is not particularly limited as long as it is an insulating resin material, but the housing 2 shown in the embodiment is molded using a polycarbonate resin material.

その構造は、図12乃至16にその外観形状を示したように、ハウジング本体20Aと蓋体20Bとからなり、図12の正面図における左半部を略Uの字形に形成して前記コンタクト本体1における長手方向後端側部分Lを収容させ、その上部を蓋体20Bによって覆う構造としてある。この蓋体20Bは、前記コンタクト本体1における通電壁11a,11aの上に被覆電線3を載置した後に上部から加圧してハウジング本体20Aに対して取り付けることによって、被覆電線3を電気的圧接用通電溝11内に同時に押し込んで、図18のように通電可能状態とする。このとき、コンタクト本体1における長手方向中間部分Mの平行壁14部分及び先端側部分Nのコンタクト部13も、図18のようにそれぞれハウジング本体20A内に配置される。   As shown in FIGS. 12 to 16, the structure is composed of a housing main body 20A and a lid 20B. The left half of the front view of FIG. 1, the rear end portion L in the longitudinal direction is accommodated, and the upper portion thereof is covered with the lid 20B. The lid 20B is used for electrical pressure welding of the covered electric wire 3 by placing the covered electric wire 3 on the current-carrying walls 11a and 11a of the contact main body 1 and then applying pressure to the housing main body 20A by applying pressure from above. By simultaneously pushing into the energization groove 11, the energization is possible as shown in FIG. At this time, the parallel wall 14 portion of the longitudinal intermediate portion M and the contact portion 13 of the tip end portion N of the contact body 1 are also arranged in the housing body 20A as shown in FIG.

而して、該ハウジング2は、図16の右側面図、図17のコネクタ二体を対向配置させた外観斜視図のように、コンタクト本体1における長手方向中間部分Mと先端側部分Nを覆わせる先端側の所定長さ部分を上下に分割させて、互いに嵌合可能な大きさとした大形の庇部分27と小形の挿入部分28とに形成し、大形の庇部分27に係止穴23を設け、その対称箇所に係止突起24を突出形成してあるものとし、二体連結時にこれらの係止穴23と係止突起24とが互いに契合して抜け止め作用を果たす用にしてある。   Thus, the housing 2 covers the intermediate portion M in the longitudinal direction and the tip end portion N of the contact body 1 as shown in the right side view of FIG. 16 and the external perspective view in which the two connectors of FIG. A predetermined length portion on the distal end side is divided into upper and lower portions, and is formed into a large flange portion 27 and a small insertion portion 28 that are sized to fit with each other, and a locking hole is formed in the large flange portion 27. 23, and a locking projection 24 is formed protruding from the symmetrical portion, and when the two bodies are connected, the locking hole 23 and the locking projection 24 are engaged with each other to perform a retaining function. is there.

換言すると、該ハウジング2は、図18のコネクタ二体の接続状態説明用の中央縦断面図に示したように、一端側に電線挿通孔21を備えていて、コンタクト本体1の抜け止め突起12と契合する契合段部22を大形庇部分27の基部に備え、二体のハウジング2,2どうしの結合時に抜け止め作用を果たす係止穴23と係止突起24とが形成されている構造としたものである。   In other words, the housing 2 includes a wire insertion hole 21 on one end side as shown in the central longitudinal sectional view for explaining the connection state of the two connectors in FIG. The engagement step portion 22 that engages with the base portion of the large collar portion 27 is provided, and a locking hole 23 and a locking projection 24 are formed that serve to prevent the two housings 2 and 2 from being detached. It is what.

各図は理解を容易にするため大きく図示してあるが、本実施例に示したコネクタの大きさを参考までに記載すると、図1に示したコンタクト本体1の左右長は23〜25mm、図12に示したハウジング2の左右長は25〜27mm程度のものである。この大きさは接続する被覆電線の線径・通電力の大きさにより異なる。   Although each figure is greatly illustrated for easy understanding, if the size of the connector shown in this embodiment is described for reference, the left and right length of the contact body 1 shown in FIG. The left and right length of the housing 2 shown in Fig. 12 is about 25 to 27 mm. This size varies depending on the diameter of the covered electric wire to be connected and the size of the power transmission.
