In addition, in Japanese Utility Model Laid-Open No. 4-24267, as shown in FIG.
There is disclosed a structure of an electric wire connecting portion in which electric wires a are bound by using a clamp member d which is variable according to the outer diameter of the electric wire, and an elastic resin cap c ′ is covered.

However, the resin cap c or c '
When the above-mentioned structure of the electric wire connecting portion covered with the above is applied to an electric wire connecting portion in an electric connecting box such as a relay box or a junction box used for electric wiring of an automobile or the like, as shown in FIG. The resin cap c fitted to the electric wire connection portion hangs down on the bottom wall g of the electric connection box f accommodating the electric component e such as a relay, and rainwater h or the like that has entered the electric connection box f is discharged from the drain port i. When the resin cap c touches the rainwater h, the electric wire connection part inside gets flooded,
It has a problem that a failure due to poor insulation occurs.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an electric connection box is provided by providing a cylindrical body for accommodating a wire connection portion in the electric connection box. The wire connection part of the wire housed inside is securely protected,
It is an object of the present invention to provide a storage structure for an electric wire connection portion that can prevent the occurrence of failures such as poor insulation due to water immersion.

[0005]

In order to achieve the above object, the storage structure of the electric wire connecting portion of the present invention stores the electric wire connecting portion in which the conductor portions of a plurality of electric wires are connected to each other in the electric connection box. A storage structure for an electric wire connection part, in which a tubular body with a closed end is erected in a structure inside the electrical connection box, and an electric wire holder is attached in the vicinity of the tubular body, It is characterized in that the introduced electric wire is supported via the electric wire holder, and the electric wire connecting portion of the electric wire is housed in a tubular body. It is effective that the cylindrical body is erected vertically with its head facing upward (claim 2). The structure is preferably a wiring board on which electric parts are arranged (claim 3). The electric wire holder is preferably an electric wire holder composed of a pair of holding hooks bent so as to face each other (claim 4).

[0006]

According to the present invention, since the wire connecting portion of the wire to be housed in the electric junction box is housed in the cylindrical body erected on the structure such as the wiring board, the wire connecting portion can be securely connected. Protected by. In addition, since the electric wire connection part does not hang down on the bottom wall of the electric connection box, the electric wire connection part will not be flooded even if rainwater or the like enters the electric connection box, and there will be no damage such as insulation failure due to water infiltration. Occurrence can be prevented.

1 is a longitudinal sectional view showing the internal structure of a relay box 1 as an example of an electrical junction box according to an embodiment of the present invention. The relay box 1 includes a box body 2 formed by molding an electrically insulating synthetic resin material, and an upper cover 3 and a lower cover 4 attached to the box body 2. The formed wiring board 5 is provided.

A plurality of relays 6 are arranged on one surface 5a of the wiring board 5, and a cylindrical body 7 for accommodating the electric wire connecting portion is provided upright adjacent to the relays 6. . Electric wires 8 connected to a plurality of relays 6 are arranged on the other surface 5b of the wiring board 5, and are connected to an external circuit through an electric wire introduction port 9 formed in the lower cover 4. 1
0 is a drainage port.

The tubular body 7 is formed in the shape of a rectangular tube having a rectangular cross section, the head portion 7a is sealed, and the base portion 7b is joined to the wiring board 5 substantially vertically. As shown in FIG. 2, an insertion port 7c for inserting the electric wire 8 is opened on the other surface 5b of the wiring board 5 which is connected to the base portion 7b of the tubular body 7.

Near the insertion opening 7c, L-shaped holding hooks 11 are provided as electric wire holders so as to face each other. The opposite ends 11a, 11a of the holding hooks 11, 11.
A slight gap 12 is provided between them, and as shown in FIG. 3, the electric wire 8 can be sequentially inserted between the holding hooks 11 and 11 through the gap 12 in a single wire state.

Among the electric wires 8 arranged on the other surface 5b side of the wiring board 5, those which need to be connected to each other have their conductor portions connected to each other to form an electric wire connecting portion 8a. . In order to store the electric wire connecting portion 8a of the electric wire 8 in the tubular body 7, first, the electric wire connecting portion 8a is inserted into the tubular body 7 through the insertion port 7c, and then each electric wire 8 is held by one hook 11. The gap 12 between 11 is passed and it inserts between the holding hooks 11 and 11.

In the above-described embodiment, an example is shown in which one tubular body 7 is used and a pair of holding hooks 11 as electric wire holders are installed, but the number of tubular bodies and electric wire holders is not limited to this. However, the number can be increased and the installation positions can be arbitrarily set as necessary.

[0013]

According to the present invention, since the wire connecting portion of the wire to be housed in the electric connection box is housed in the tubular body, the wire connecting portion is reliably protected and the wire connecting portion is electrically connected. Since it does not hang down on the bottom wall of the junction box, even if rainwater, etc., enters the electrical junction box, the wire connection will not be exposed to water, preventing failures such as insulation failure due to water leakage Is significantly improved.
