The present invention relates to a connection joint connector. Specifically, the present invention is to joint electric wires constituting a wire harness arranged in a vehicle, and in particular, to enable a plurality of joint connectors to be efficiently connected and arranged.

As a combination of a plurality of joint connectors connected to the wires of this type of wire harness,

joint connectors

100A and 100B of the same type shown in FIGS. 10A and 10B in Japanese Patent Laid-Open No. 9-237668 (Patent Document 1). Have been proposed, and a joint joint connector 100 is proposed which is connected in the lateral direction using a cover 102. The

mating connectors

101A and 101B to which a plurality of wire terminals constituting the wire harness are connected are fitted and connected to the

joint connectors

100A and 100B, respectively. The terminal t1 connected to the electric wire terminal is fitted into the terminal t2 branched from the

140A and 140B are connected to both surfaces of the joint connector 130.

JP-A-9-237668

In the connection joint connector of Patent Document 1, since a plurality of joint connectors are connected in parallel, the lateral width of the connection joint connector is increased, and the width in the direction orthogonal to the wire connection direction is increased. When these connection joint connectors are mounted on the main line of the wire harness, the width of the connection joint connector becomes larger than the outer diameter of the main line, and the connection joint connector protrudes outward from the main line of the wire harness and cannot be used. Therefore, the connection joint connector is not limited to a wire harness but mounted on a vehicle body such as a vehicle body frame.

Moreover, also when connecting in the up-and-down lamination | stacking state shown to FIG. 11 (A), a connection joint connector cannot be stably mounted on a wire harness, but is limited to vehicle mounting, such as a vehicle body.
Further, when connecting the mating connector to both surfaces of the joint connector shown in FIG. 11 (B), it can be mounted on the wire harness, but the number of wires that can be joined is limited, and it is not suitable when many wires are jointed. It becomes.

The present invention has been made in view of the above problems, and adopts a connection method in which a plurality of joint connectors are connected in the vertical direction so that they can be mounted on a wire harness, and the number of electric wires connected to the same circuit can be increased or decreased. The main object is to provide a connection joint connector that can be adapted.
Furthermore, it is an object to provide a connection joint connector that can form not only one joint circuit but also a plurality of joint circuits of another group.

In order to achieve the above object, the present invention is a connection joint connector for sequentially connecting a plurality of joint connectors, in which a joint bus bar is accommodated in a housing, in the vertical direction of the electric wire insertion direction,
The housing includes a main body portion provided with a plurality of terminal accommodating chambers opened in one side in parallel, a both-side connection frame projecting from the other side of the main body portion via a wire lead-out portion, and the both-side connection frame. A lock portion provided, and a shape provided with a locked portion provided on the outer surface of the main body portion for lock coupling with the lock portion;
A main body portion of the other housing is inserted between the both side connecting frames of one joint connector to be connected, and a locked portion is coupled to and connected to the lock portion of the one joint connector, and the other joint connector is connected. A connection joint connector is provided in which the electric wire connected to the cable is pulled out from the electric wire drawing portion.

When the housing of the joint connector has the above shape, a plurality of joint connectors can be connected in the vertical direction of the electric wire insertion direction. Thus, since a connection joint connector can be made into an elongate shape, it can mount on a wire harness and can be attached by winding an adhesive tape. In addition, the number of joint connectors to be connected is not limited and can be sequentially connected in columns, so that it is possible to flexibly cope with the number of electric wires to be joint-connected.

The joint connector to be connected accommodates the joint bus bar in the housing having the same shape, and the joint bus bar projects the terminal for connecting the electric wire and the terminal for connecting the joint bus bar in the opposite direction from the joint portion and connects the joint bus bar. The joint bus bar connection terminal of one joint connector and the wire connection terminal of the other joint connector can be fitted and connected.

As described above, if the joint bus bar accommodated in the housing protrudes in the opposite direction from the joint portion with the terminal for connecting the electric wire and the terminal for connecting the joint bus bar, it is necessary to connect the joint bus bar of the joint connector to be connected. It can be easily connected when there is a cable, and can correspond to the number of wires to be connected jointly.

One joint bus bar having the same shape is accommodated in the housing of each joint connector, the joint bus bars of the joint connector to be connected are sequentially connected, and all the wires connected to the joint connector to be connected are jointly connected to one circuit. It is good also as a structure.

Or you may divide | segment the joint bus bar accommodated in the housing of one joint connector into one or several so that it can divide | segment into a some joint group and can jointly connect an electric wire.
For example, one first joint bus bar is accommodated in the first joint connector, and the second joint bus bar and the third joint bus bar are accommodated in the second joint connector connected to the first joint connector. The bus bar is connected to the first joint bus bar, and the third joint bus bar is connected to the fourth joint bus bar in the third joint connector connected to the second joint connector. By repeating this in sequence, a plurality of joint groups can be formed by the connected joint connector.
In this way, it is possible to cope with an increase or decrease in the number of wires to be joined and the number of joint groups.

The housing for the joint connector may be provided with terminal accommodating chambers in a single row, or may be provided with a plurality of upper and lower terminal accommodating chambers. For the upper and lower multi-stage terminal accommodating chambers, terminals for connecting electric wires projecting from the joint portion of the joint bus bar at upper and lower multi-stages are inserted.

As described above, the connection joint connector of the present invention is configured so that the joint connectors can be sequentially connected in the vertical direction along the direction of insertion of the electric wires into the joint connector. It becomes. Therefore, the installation space of the connection joint connector is not increased, and the connection joint connector can be mounted on the wire harness, and the connection joint connector mounted on the wire harness can be easily attached by being wound around the wire harness with an adhesive tape.

Also, according to the number of wires to be jointed, the number of joint connectors to be sequentially connected in the vertical direction may be adjusted, improving usability. In addition, connection and disconnection of the joint bus bar accommodated in the joint connector to be sequentially connected can be arbitrarily selected, and all the wires connected to the joint joint connector can be joined to one circuit, and a plurality of joint groups can be connected.
