They are fitted in a positional relationship.

In the connection portion main body 14, the connector 22 and each connector 34 are connected to each other via a flexible wiring member 46. The flexible wiring member 46 is a sheet-like wiring member in which a printed wiring forming a branch conductive path is covered with an insulator. As shown in FIG.

When the connectors 34 are connected to the board P as described above, the branch conductive paths of the flexible wiring member 46 are incorporated into the wiring circuit of each board P, thereby connecting the electrical components to each other. A J / B circuit is configured.

The connector 22 and the flexible wiring member 46
The connection is made by inserting the base end of the terminal 28 protruding from the connector 22 into the flexible wiring member 46 and soldering it to the printed wiring. On the other hand, the connection between the connector 34 and the flexible wiring member 46 is such that the connection piece 39 of the terminal 38 protruding from the connector 34 is inserted into the flexible wiring member 46 and soldered to the printed wiring, and is protruded from the connector 34. This is performed by inserting a cylindrical fixing piece 37 into the flexible wiring member 46 and caulking the flexible wiring member 46.

In the J / B 10 configured as described above,
After the substrate container 12 and the connection portion main body 14 are separately manufactured, the J / B 10 is configured by fitting the substrate container 12 and the connection portion main body 14 together and assembling them together.

At this time, the substrate container 12 and the connecting portion main body 14 are fitted in a fixed positional relationship by the projections 48 and the guide holes 13 as described above. Since the displacement and tilting of the connector 34 are appropriately allowed, even if there is an error in the relative mounting position of the connector 34 or the board P, the connector 34 is displaced or tilted so as to absorb the error, and According to the flexible wiring member 46
Is flexed and deformed, whereby the connection between each connector 34 and the substrate P is properly performed.

Moreover, in the configuration of the J / B 10, the flexible wiring member 46 having the branch conductive path is bent and deformed, so that the connector 22 and the flexible wiring member 4 are not bent.
6 and the connector 34 are directly connected electrically, and the displacement of the connector 34 is allowed, so that this type of conventional device requires a relay terminal to absorb errors such as the mounting position of the board. In comparison, since the relay terminal is not required, the configuration is simple and the whole apparatus can be effectively made compact.

Further, in the conventional apparatus, when connecting the wiring board and the printed circuit board, relay terminals are required by the number of contact portions and terminals to be connected to each other, and the mounting positions of these relay terminals are adjusted respectively. While it is necessary to connect the wiring board and the printed circuit board, the above J / B10 does not require any such complicated work, so that the productivity of the J / B10 can be significantly improved. There is also.

Further, in the above J / B10, the connector 2
2 and the connector 34 are arranged on the back of each other, and the upper and lower ends of the flexible wiring member 46 are folded back to connect the connectors 22 and 34. Therefore, the portion forming the branch conductive path in the connection portion main body 14 is compactly stored. Never bulky. Therefore, this also contributes to downsizing of the entire apparatus.

By the way, the J / B constructed as described above
In the case of 10, the J / B 10 can be efficiently manufactured by manufacturing the connection portion main body 14 by a method as shown in FIG. Hereinafter, this manufacturing method will be described.

First, the connectors 22 and 34 are connected to the connecting bar 50.
(FIG. 6 (a)) is formed by a mold with a connected body which is integrally connected through the above. At this time, the connectors 22 and 32 are arranged such that the connectors 34 are arranged on both sides of the connector 22, and the terminals 28 and 38 are integrally formed with the connectors 22 and 34. The connectors 22 and 34 are formed in the same direction, that is, in such a manner that the front sides of the connectors are directed in the same direction.

Each of the molded connecting members is connected to each terminal 2 projecting outward.
8 and 38 are mounted so that the base end and the fixing piece 37 are directed upward. Then, the flexible wiring member 46 is connected to the connecting body while inserting the terminals 28, 38 and the fixing piece 37 into the corresponding perforated portions. It is placed on the surface (FIG. 6B).
Then, each terminal 2 is connected to the flexible wiring member 46.
8 and 38 are collectively soldered and fixed pieces 3
7 is caulked to the flexible wiring member 46, whereby the connectors 22 and 34 of the connector are integrated with the flexible wiring member 46.

Thereafter, the connecting bar 50 is cut off from each of the connectors 22 and 34, and the support body 24 formed in advance by a mold is mounted on the connector 22 from the upper surface side of the flexible wiring member 46 (FIG. 6B, (C)).
The support 24 is mounted by engaging the hook 23a of the connector 22 with the edge of the locking hole 29a formed in each side wall 25b and engaging the locking portion 23b formed at the center of the connector 22 in the width direction. Hook 2 formed on main body 25a
9b is locked. At this time, hook 29b
Is an opening 46 formed in the flexible wiring member 46.
a, and is locked to the locking portion 23b.

When the mounting of the support 24 to the connector 22 is completed in this manner, each connector 34 is inverted while bending both ends of the flexible wiring member 46 and mounted on the connector holding portions 30a and 30b of the support 24 (FIG. 6
(D)). At this time, after each connector 34 is inverted, the connector 34 is pushed into the corresponding locking hook 32 from the flange portion 35 side, and the locking hook 32 is inserted into the flange portion 35.
, Each connector 34 can be easily mounted on the connector holding portions 30a, 30b, whereby the connection portion main body 14 is completed.

According to the manufacturing method of the connecting portion main body 14, first, the connectors 22 and 34 are arranged side by side and integrally molded, so that the terminals 28 and 38 can be driven from one direction. In addition, the flexible wiring member 4
6, the connectors 22, 34 are connected by the connecting bar 50, and the positional relationship between the terminal 28 on the connector 22 and the terminal 38 on the connector 34 is maintained. Can be extremely easily assembled. Further, each terminal 28, 38
And the flexible wiring member 46 can be soldered to all the terminals 28 and 38 from one direction. In addition, all of the above steps can be easily performed in the line process. Therefore, the connecting portion main body 14 can be produced extremely efficiently.

The J / B10 constructed as described above
Is an example of the electrical connection device according to the present invention, and its specific configuration can be appropriately changed without departing from the gist of the present invention.

For example, in the above-mentioned J / B10, the contact portion Pb is provided at the edge of the substrate P, and the connector 34 is fitted directly to the edge of the substrate P. Alternatively, the connecting portion main body 14 and the board P may be connected to each other via a connector. However, the above J / B
If the connector 34 is directly connected to the edge of the board P as in 10, there is an advantage that the connection structure can be simplified since the connector on the board P is not required.

Further, in the connection portion main body 14, a gap L is provided between the flange portion 35 of the connector 34 and the rising portion 32a to allow the displacement of the connector 34. Since the connector 34 is apt to be held biased from the theoretical position, that is, the center position of the range in which the connector 34 can be displaced, due to the weight of the connector 34, instead of the locking hook 32, for example, as shown in FIG. A locking hook 32 'for holding the connector 34 at its tip may be employed. By doing so, it is possible to allow the displacement of the connector 34 while holding the connector 34 at the theoretical position and flexing and deforming the hook tip at the time of connection.

Further, when connecting the connector 34 to the flexible wiring member 46, the connecting piece 39 of the terminal 38 is soldered to the flexible wiring member 46, and the fixing piece 37 provided on the connector 34 is connected to the connector 34.
However, it is not always necessary to provide the fixing piece 37 and to caulk the fixing piece 37 to the flexible wiring member 46. However, in the configuration of the connection portion main body 14 in which the flexible wiring member 46 is bent and deformed, concentration of stress on the soldered portion of the terminal 38 may cause connection failure such as cracking of the soldered portion. It is preferable to fix the fixing piece 37 to the flexible wiring member 46 like the connection part main body 14 so as to reduce the concentration of stress on the soldered portion. Further, in the connection portion main body 14, the fixing piece 37 is provided only for the connection between the connector 34 and the flexible wiring member 46, and is fixed to the flexible wiring member 46. Of course, the connector 22 and the flexible wiring member 46 are connected. This structure can also be adopted for connection with the.

Further, a configuration as shown in FIG. 8 may be adopted as a configuration which can improve the assembling and maintenance of the J / B 10.

That is, the case 1 of the base container 12
6, a base 16a having a bottom plate and a side wall and a cover 16b having a top plate and a rear wall, as shown in FIG. Is also good. In this way, by removing the cover 16b, the board P can be easily attached to and detached from the case 16. This is advantageous in assembling and maintaining the J / B 10. In this case, as a fixing structure of the base 16a and the cover 16b, for example, a hook 52 may be formed on the base 16a as shown in FIG. These may be used to fix each other.

[0049]

As described above, the present invention comprises a printed circuit board, which is connected to an electric wire of a wire harness via a wiring member. The printed circuit board is fixedly supported by the supporting member. Since the supporting member is provided with a harness connecting member and a board connecting member to be connected to the printed board, and these connecting members are interconnected by a sheet-shaped flexible wiring member, the printed board and the board connecting member are connected to each other. In connection with the flexible wiring member, it is possible to absorb a mounting error or the like of a printed circuit board or the like according to the bending deformation of the flexible wiring member. Therefore, there is no need to provide a special member for absorbing errors separately,
The circuit can be configured by appropriately incorporating the wiring circuit of the printed circuit board into the branch conductive path of the flexible wiring member with a compact configuration.

In particular, in such a configuration, if the contact portion is provided at the edge of the printed circuit board, and the connecting member for the board is provided with a connecting portion having a U-shaped cross section which can contact the contact portion, the printed circuit board can be printed. There is no need to provide a connector on the substrate side, and the connection structure can be effectively simplified.

In the case where the supporting member is composed of a first and a second supporting member which are assembled to each other in a fixed positional relationship, the printed circuit board is provided on the first supporting member and the connecting members are provided on the second supporting member. 2 If the connecting member for a substrate is held so as to be swingable with respect to the support, when assembling each support,
It is possible to suitably absorb a mounting error or the like of a printed circuit board or the like due to the swing of the board connecting member.

Further, the harness connecting member and the board connecting member are arranged on the back of each other, and the flexible wiring member is
If the connection member is connected to each connection member in a state of being bent in a letter shape, it is possible to make the device more compact.

Further, if the respective terminals of the harness connecting member and the board connecting member are soldered to the flexible wiring members, respectively, the flexible wiring members are connected to the respective connecting members. The connection members can be connected collectively, thereby improving productivity. In this case, if at least one of the harness connection member and the board connection member is fixed to the connection member at a portion other than the connection portion to the terminal, the bending deformation of the flexible wiring member is performed. This alleviates the stress concentration on the soldered portion, thereby making it possible to effectively prevent poor connection due to solder cracks and the like.

Further, the first support has a box-shaped case,
If the printed circuit board is arranged inside the case, this case is attached to the base on which the printed circuit board is mounted, and the case is detachably mounted on this base. With this configuration, assembling and maintenance can be effectively improved.

And, they are integrally formed in a state where they are connected to each other via a connecting portion, and the flexible wiring member is placed over each connecting member and fixed to each connecting member, and the connecting portion is cut to separate each connecting member. Then, a holding member having a mounting portion for the board connecting member on the upper surface side is laminated and fixed to the harness connecting member with the flexible wiring member sandwiched therebetween, and then connected to the board. Since the material is inverted and attached to the attachment portion of the holding member to be integrated, firstly, each terminal can be driven from one direction, and secondly, the positional relationship of each terminal can be maintained. Third, soldering of each terminal and the flexible wiring member can be performed for all terminals from one direction, and fourthly, each of the above-described steps can be performed. Can be easily performed in the line process. Therefore, the second
