Description

本考案は、被覆電線から分岐電線を必要とする任意の箇所から分岐電線を分岐させることができるようにした電線分岐コネクタである。より詳しくは、分岐電線の先端部に予め連結させた端子を被覆電線の導電体と連通する部分と接触させて電気的に確実に分岐させることができるようにした電線分岐コネクタに関するものである。 The present invention is a wire branch connector that can branch a branch wire from an arbitrary place that requires a branch wire from a covered wire. More specifically, the present invention relates to a wire branch connector in which a terminal connected in advance to the tip of a branch wire is brought into contact with a portion communicating with a conductor of a covered wire so as to be surely branched electrically.

従来から、電線ケーブルどうしを電気的に接続させて分岐線を得るようにした電線分岐コネクタは、コネクタに対して複数本の電線ケーブルを並列的に差し込む操作によって、差し込んだ複数本の電線ケーブルどうしを電気的に接続するようにしたものが多く提案されている（例えば、後記特許文献１参照）。 Conventionally, an electric wire branch connector in which electric wires are electrically connected to obtain a branch line is obtained by inserting multiple electric wires into the connector in parallel. There are many proposals in which these are electrically connected (see, for example, Patent Document 1 below).

他方、電線の先端部に通電用の端子金具を予め連結しておき、この端子金具を連結した複数本の電線ケーブルをコネクタのハウジングに差し込んで、ハウジング内の電導板を介して複数本の電線ケーブルどうしを電気的に接続するようにしたものも提案されていて既に周知である（例えば、後記特許文献２参照）。 On the other hand, a current-carrying terminal metal fitting is connected in advance to the tip of the electric wire, and a plurality of electric cables connected to the terminal metal fitting are inserted into the housing of the connector, and a plurality of electric wires are connected via the conductive plate in the housing. A cable in which cables are electrically connected has been proposed and already known (for example, see Patent Document 2 below).

これらの電線分岐コネクタには、２本の電線だけを接続するようにしたもののみならず３本の電線を接続するもの、４本接続用のもの、さらに多くの本数を接続するようにしたものも知られており、また、接続した電線の内の１本をアース線として使用することも適宜に行われている。そして、これらの電線分岐コネクタは、何れのものもコネクタの内部に挿入してある通電金具に、ケーブルどうしを直接に接触させるか、またはケーブルの先端に予め取り付けた端子金具を介して接触するようにしたものも知られている。 These wire branch connectors are not only those that connect only two wires, but also those that connect three wires, those that connect four wires, and those that connect more It is also known that one of the connected wires is used as a ground wire as appropriate. And these electric wire branching connectors are made so that the cables are brought into direct contact with the current-carrying metal fittings inserted into the connectors, or via the terminal metal fittings attached in advance to the ends of the cables. The ones made are also known.

前者の特許文献１に記載の電線分岐コネクタにあっては、電線径が直径１〜１．５ｍｍ程度の圧入強度を備えた比較的太い線径の電線を用いることが多い。後者の特許文献２に記載の電線分岐コネクタにあっては、電線自体が差し込み強度を備えているもののみならず、差し込み強度の小さい細径電線や多数細線の集束電線にも使用されている。 In the former electric wire branch connector described in Patent Document 1, an electric wire having a relatively thick wire diameter having a press-fitting strength of about 1 to 1.5 mm in diameter is often used. In the latter electric wire branching connector described in Patent Document 2, the electric wire itself is used not only for the wire having the insertion strength, but also for a small-diameter electric wire having a low insertion strength or a multi-thin focusing wire.

本考案は、被覆電線の任意の箇所から通常の被覆電線や、必要に応じて例えばアース線のような電線自体が差し込み強度に乏しい電線であっても、確実に分岐線を分岐させることができるようにした電線分岐コネクタの提供を目的としたものである。 The present invention can reliably branch a branch line from an arbitrary portion of a covered electric wire even if it is a normal covered electric wire or, if necessary, an electric wire itself having a low insertion strength such as a ground wire. An object of the present invention is to provide an electric wire branch connector.

Thus, the molded product body 1 is perpendicular to the press-fitting groove 12, and the coated-wire placing guide groove 11 opened toward the upper surface, the covered-wire press-fitting groove 12 formed below the guide groove 11, and the press-fitting groove 12. A branch wire insertion opening 14 formed in the wall surface 13, a branch wire insertion cavity 15 formed below the covered wire press-fitting groove 12 at the inner back of the opening 14, and the covered wire placement guide groove 11 is formed on both side walls 16 and 17 parallel to 11 18 and 18, and the lid body 2 protrudes upward on both outer sides parallel to the protrusion 21, and a protrusion 21 inserted into the guide groove 11 for covering the covered wire in the molded product body 1. Protruding walls 22 and 23 for fitting with the formed molded product main body 1, and an opening 24 that engages with the lid hooking projections 18 and 18 in the molded product main body 1 formed on each of the protruding walls 22 and 23. , 24, and the connecting body 3 has a thin thin strip shape, and both ends of the connecting body 3 are adjacent to the lid body 2 in the molded body 1 and the molded body in the lid 2. 1 is connected to the projecting wall 22 on the side adjacent to 1, and the energizing metal fitting 4 has a U-shaped cut energizing portion 42 that breaks the sheath of the sheathed wire by pressing force and contacts the internal conductor. 41 and a contact piece for energizing branch wires formed at a predetermined interval 3, the current-carrying portion 42 of the conductive piece 41 is disposed facing the guide groove 11 for placing the covered electric wire in the molded product main body 1, and the contact piece 43 is for inserting the branch electric wire in the molded product main body 1. In the cavity 15, the branch wire receiving portion 44 is arranged so as to face the branch wire insertion opening 14.

また、請求項２に記載の電線分岐コネクタは、前記請求項１に記載の電線分岐コネクタに従属する構成であって、成型品本体１に形成された蓋体掛止突起１８，１８と、蓋体２に形成された開口部２４，２４とが、被覆電線載置用案内溝１１の長手方向に沿って、それぞれ２箇所ずつ形成させてある構成としたものである。 Moreover, the electric wire branch connector according to claim 2 is a configuration subordinate to the electric wire branch connector according to claim 1, and includes lid body latching protrusions 18, 18 formed on the molded product body 1, The openings 24, 24 formed in the body 2 are configured to be formed at two locations along the longitudinal direction of the covered wire placement guide groove 11.

本考案に係る電線分岐コネクタは、このように、被覆電線に対して分岐線の必要な任意の箇所において、通常の被覆線やアース線のような電線を電気的に接続させて分岐線として使用することができるようにしたものであるから、被覆電線が既設の電線であっても、分岐電線を引き出しておく必要性のある任意の箇所で、必要な分岐電線を被覆電線から任意に分岐させることができるという顕著な効果を期待できるものである。 In this way, the wire branch connector according to the present invention is used as a branch line by electrically connecting a wire such as a normal covered wire or a ground wire at any place where a branch wire is required with respect to the covered wire. Therefore, even if the covered electric wire is an existing electric wire, the necessary branch electric wire is arbitrarily branched from the covered electric wire at any place where the branch electric wire needs to be pulled out. It can be expected to have a remarkable effect.

さらに、電線案内溝と直交する壁面に分岐電線挿入用開口を形成し、分岐電線挿入用空洞をその内奥部において電線圧入溝の下方に形成してあるので、分岐させる電線を被覆電線と平行な姿勢で取り出すことができるので、分岐線取り出し部をコンパクトに形成できるという実用上の利点も有している。 Furthermore, the branch wire insertion opening is formed in the wall surface orthogonal to the wire guide groove, and the branch wire insertion cavity is formed below the wire press-fitting groove in the inner back thereof, so that the wire to be branched is parallel to the covered wire. Since it can be taken out in a simple posture, it has a practical advantage that the branch line takeout portion can be formed compactly.

さらに、本考案の請求項２に記載の電線分岐コネクタは、成型品本体に形成した蓋体掛止突起と蓋体に形成した開口部とを、それぞれ２箇所ずつ形成させてあるので、成型品本体と蓋体とを確実に閉塞状態としておくことができるという利点を有している。 Furthermore, in the electric wire branch connector according to claim 2 of the present invention, since the lid hooking projection formed on the molded body and the opening formed on the lid are formed at two locations, respectively, There is an advantage that the main body and the lid can be reliably closed.
