Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a branch connection portion of a ribbon electric wire that connects a branch wire made of a single wire to a specific core wire of the ribbon electric wire.

(Prior art) Conventionally, when connecting a branch wire made of a single wire to a specific core wire of a ribbon electric wire, the insulation coating of the specific core wire of the ribbon wire is stripped off and the core wire of the branch wire is connected to that core wire. They were soldered and the branch connections were wrapped with insulating tape to insulate them.

(Problems to be Solved by the Invention) However, this method of branch connection has the disadvantage that branch connection work is extremely time-consuming and labor-intensive. Further, since a branch wire made of a single wire is connected to a specific core wire of the ribbon electric wire, there is a drawback that it is difficult to insulate the branch connection portion.

(Purpose of the invention) An object of the invention is to provide a branch connection part for a ribbon electric wire that can easily branch and connect a branch line made of a single wire to a specific core wire of the ribbon electric wire.

(Means of the Present Invention for Solving Problems) The present invention provides that, in a branch connection section of a ribbon electric wire in which a branch line made of a single wire is connected to a specific core wire of the ribbon electric wire, a particular core wire of the ribbon electric wire is located at a branch position. The insulation coating is cut together with a through hole, and a through hole is made.
A first connector housing is provided with a bottom surface of a connector housing in contact with one surface of the ribbon electric wire at the position of the through hole, and a slot is press-fitted to both ends of the cut core wire in the connector housing. A second slot terminal, a third slot terminal press-fitted into the core wire of the branch wire, and a short-circuit conductor for short-circuiting these slot terminals are incorporated, and a short-circuit conductor is installed on the other surface of the ribbon wire together with the connector housing. A first presser cover is provided to sandwich the ribbon electric wire, and the connector housing and the first presser cover are connected to each other by a connecting piece that passes through a through hole of the ribbon electric wire, and the connector housing is attached to an upper surface of the connector housing. The present invention is characterized in that the connector housing and the second presser cover that clamps the branch line are connected by a connecting piece.

(Operation of the invention) According to the branch connection part of the ribbon electric wire having such a structure, the branch connection work can be performed by simply fitting the connector parts, so it is possible to efficiently perform the branch connection of the branch line consisting of a single wire. can. Also,
Since the connector is attached to the ribbon wire using the through hole provided in the ribbon wire, it can be firmly attached to the ribbon wire, and the branch connection portion can be easily insulated using this connector.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 10, in the branch connection section of the ribbon electric wire of this embodiment, a specific core wire 2' of the plurality of core wires 2 of the ribbon wire 1 as the main wire is insulated at the branch position. The ribbon wire 1 is cut to a length L together with the coating 3, and a through hole 4 is provided in the ribbon wire 1. The formation of such a through hole 4 is performed using, for example, a die 5 and a punch 6.

One surface of the connector housing 7 is disposed in contact with one surface of the ribbon electric wire 1 at the position of the through hole 4 . The connector housing 7 includes both ends 2a', 2 of the cut core wire 2' of the ribbon wire 1.
The first one has slots 8A and 9B press-fitted into b',
The second slot terminals 8 and 9, the third slot terminal 12 in which the slot 12A is press-fitted to the core wire 11 of the branch line 10 made of a single wire, and the short-circuit conductor that short-circuits these slot terminals 8, 9, and 12. 13 is incorporated. The shorting conductor 13 is placed on the bottom plate 14 in the connector housing 7, and is connected to the first and second
The slot terminals 8 and 9 are located in the holes 15 and 16 of the bottom plate 14.
It is protruding from the outside. Connector housing 7
A connecting piece 17 is provided protruding from the bottom surface. This connecting piece 17 passes through the through hole 4 of the ribbon electric wire 1 and projects to the other side.

Ribbon wire 1 corresponding to connector housing 7
A first presser cover 18 is in contact with the other surface of the presser cover 18 . This first presser cover 18 is provided with a connecting piece locking hole 19 for locking the connecting piece 17 of the connector housing 7 . Due to the locking action of the connecting piece 17 and its locking hole 19, the connector housing 7 and the first presser cover 18 are connected to each other while holding the ribbon wire 1 therebetween, and are attached to the ribbon wire 1. The first holding cover 18 is provided with a pair of terminal fitting recesses 20 and 21 on the surface from which the connecting piece 17 projects, and the first and second slot terminals 8 and 9 passing through the ribbon electric wire 1 are provided therein. The tips of each are accommodated.

A second holding cover 22 is fitted onto the upper surface of the connector housing 7 to sandwich the connector housing 7 and the branch line 10 . The second presser cover 22 has a lock recess 2 of the connector housing 7.
A lock protrusion 24 that is engaged with the lock 3 is provided in a protruding manner. The second presser cover 22 has a terminal fitting recess 2.
5 is provided, and the tip of the third slot terminal 12 is housed therein.

In such a branch connection section of a ribbon electric wire, both ends 2a' and 2b' of the cut core wire 2' are connected via the first and second slot terminals 8 and 9 and the shorting conductor 13, This core wire 2' and the core wire 11 of the branch wire 10 are branch-connected via a shorting conductor 13 and a third slot terminal 12.

(Effect of the invention) As explained above, according to the branch connection part of the ribbon electric wire according to the present invention, the branch connection work can be performed by simply fitting the connector parts, so that the branch connection of the branch line made of a single wire can be efficiently performed. It can be performed. In addition, the connector is attached to the ribbon wire by interconnecting the connector housing and the first presser cover by inserting a connecting piece into the through hole provided in the ribbon wire, so that the connector can be firmly attached to the ribbon wire. It is possible to easily install the connector and insulate the branch connection portion with such a special structure connector.
