Description

[Detailed Description of the Invention] [Industrial field of application] The present invention integrally couples an electronic circuit unit (hereinafter abbreviated as a unit) and a through connector to a junction block (hereinafter abbreviated as JB). The present invention relates to an electric connection device for an automobile, which can be fixed.

[Conventional technology]

In recent years, the number of in-vehicle electric components has been increasing more and more to pursue safety, comfort and functionality of automobiles. Equipment has increased.

On the other hand, the space inside the vehicle is limited, and it has become difficult to secure a space for arranging a large number of electrical components and control devices as well as a space for arranging a wire harness.

Therefore, mainly for the JB that absorbs the branch circuit of the wire harness by the bus bar, a unit that mounts electronic circuit parts on the printed circuit board and forms various control circuits and a through connector that directly connects the wire harnesses are integrated. The electric connection device for automobiles is being developed, which can be connected to, and the wiring can be centralized in a space-saving manner.

FIG. 2 shows an example of a conventional device (Japanese Utility Model Publication No. 63-127223). In the figure, 1 is a JB body, 2 is a unit, and both are circuit-connected by coupling connectors 3 and 4.
A circuit directly connected to each auxiliary device (for example, an antitheft circuit unit) from the unit 2 without requiring a circuit connection to the main body 1 is connected by the unit direct connection connectors 5 and 6.

Further, a bracket 7 for fixing a through connector is provided on the side surface of the JB main body 1, one of the through connectors 8 is attached to this, and a mating through connector 9 is fitted thereto. This is for directly connecting the electric wires of the wire harnesses W and W ', which does not require connection with the internal circuits of the through connectors 8 and 9, the JB body 1 and the unit 2. In the figure, F is a fuse, R is a relay, and 10 is a relay cavity.

[Problems to be solved by the device]

In the mounting structure of the through connector 8 shown in FIG. 2, since the connector 8 projects from the side surface of the JB main body 1, it is easy to touch other devices, and because of the tensile force applied to the wire harness W, W ′. There is a risk that it will come off, JB
The overall installation space is also large.

Therefore, the present invention aims to provide an electric connection device for an automobile, which has a structure suitable for downsizing while integrally connecting and fixing the unit and the through connector to the JB and preventing the through connector from being detached. And

[Means for Solving the Problems]

In order to achieve the above-mentioned object, an electric connection device for an automobile of the present invention is a junction block (hereinafter referred to as JB).
And an electronic circuit unit (hereinafter referred to as a unit) that is connected to the circuit, and a through connector that is a female and male pair fixed to the JB and / or the unit.
A unit coupling connector and a unit fitting frame are formed on the B main body, a bracket is formed, a JB coupling connector is formed on the mating surface of the unit with JB, and a unit direct coupling connector and a connector are also formed. An insertion opening is provided side by side, and a mating connector into which the unit direct connection connector is fitted and one of the through connectors forming a pair are integrally formed to form a composite connector, and the composite connector A bracket fitting member is formed on the side surface, and the unit is fitted to the unit fitting frame to be connected to the J.
The connector for B coupling and the connector for unit coupling were coupled, and the composite connector was fixed to the side surface of JB by the engagement with the bracket and the bracket fitting member, and the unit direct coupling connector and the mating connector were coupled. In this state, the through connectors forming a pair can be connected to each other through the opening.

[Action]

In the device of the present invention, one of the through connector that forms a pair is integrated with the mating connector that is connected to the direct connector of the unit to form a composite connector,
This is fixed to the side surface of JB by a bracket fitting member.

Further, the unit has an opening for inserting a connector side by side with the direct-connecting connector, and through connectors forming a pair are coupled to each other through the opening.

Therefore, the composite connector is fixed by the double combination structure by the engagement of the bracket and the bracket fitting member and the fitting of the unit direct connection connector and the mating connector thereof, and one of the through connectors included in the composite connector is fixed. The connector also has a strong double fixing structure. As a result, disconnection of the through connector can be reliably prevented.

If the unit is not completely fitted into the unit fitting frame of the JB main unit, that is, if the unit coupling connector and the JB coupling connector are in the middle, the unit direct coupling connector and the mating connector are fitted. Since the connectors are not completely connected to each other and the through connectors cannot be connected to each other, incomplete fitting of the connectors can be prevented.

Hereinafter, the above configuration and operation will be specifically described with reference to the drawings illustrating an embodiment.

On the lower surface of the main body 11, a unit coupling connector 14 is erected and a unit fitting frame 15 is formed. One end of the unit fitting frame 15 is released, and a bracket 16 having a fitting groove 16a and a stopper wall 16b is projected from the side surface of the main body 11 so as to face the released portion.

The unit case 18 of the unit 17 has a unit fitting frame.
The case 18 is formed to have a size projecting from the open portion, and the JB coupling connector 19 is provided on one side of the fitting surface of the case 18 with the JB main body 11 and the unit direct coupling connector 20 is erected on the other side. An opening 21 for inserting the connector alongside the connector 20.

It is supported by a heavy and rigid fixing structure. Further, the composite connector 24 is in a state where the outer surface thereof is covered with the unit 17. Therefore, the through connector 26 is not locally stressed, and there is no fear of disconnection from the JB body 11. Also, JB
Main unit 11 and composite connector 24 and unit 17 for both
