Description

  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.

  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).

  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).

  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.

  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.

  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.

  The electric wire branch connector according to claim 1 of the present invention taken to achieve this object is a molded product made of a synthetic resin material having electrical insulation, and includes a molded product main body 1, a lid 2, and these From the housing member A provided with the connecting body 3 that connects the two bodies 1 and 2, and a work product made of a good conductor metal, and a current-carrying metal fitting 4 provided with a covered wire connecting portion and a branch wire conducting portion. 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.

  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.

  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.

  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.

  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.
