Abstract

PURPOSE:To prevent enlargement of a conductive foil pattern, and prevent short-circuiting by a solder bridge between terminals by arranging the respective plural terminals in a row in respective connector parts, and connecting the terminals of the respective connector parts to each other by a linear conductive foil formed on a pattern surface of a flat circuit wiring means. CONSTITUTION:Connector parts 13 are juxtaposed with each other in a resin case, and terminals 12 are arranged in a housing 11. When a terminal 12A of a connector part 13A, a terminal 12B of a connector part 13B and a terminal 12C of a connector part 13C are connected to each other, the terminals 12A, 12B and 12C are connected to each other by a linear conductive foil 14 preformed on a pattern forming surface of a printed board. Similarly when the other terminals of the connectors 13A to 13C are connected to each other, after conductive foil 14 having a plural parallel linear pattern is formed on a printed board, the respective terminals are connected to each other by the conductive foil 14. Thereby, since there is no need to form the conductive foil in a bypass pattern, enlargement of the conductive foil can be prevented.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch connection device for a wire harness used for connecting a battery of an automobile to various electric components, connecting various electric components and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, for example, a branch connecting device for a wire harness of an automobile has a resin case 1.
A plurality of connector portions 4 each having a plurality of pin-shaped terminals 2 inside a housing 3 are attached in parallel and integrated, and the thus integrated is a flat circuit wiring means excluding electric wires. After being fixed to a certain printed circuit board 5 by screwing, resin caulking or the like, the ends of the terminals 2 of each connector section 4 penetrating the printed circuit board 5 have a predetermined pattern of copper foil formed on the pattern formation surface of the printed circuit board 5. It is configured by being soldered to a conductive foil made of, for example.

By the way, as shown in FIGS. 8 to 10, the connector portion 4 is usually one in which the terminals 2 are arranged in two rows in the housing 3 in order to reduce the dimension L in the lateral width direction. There is.

[0004]

However, for example, as shown in FIG.
As shown in FIG. 3, three connector portions 4 each having eight terminals are arranged side by side, and when these are referred to as a first connector portion 4A, a second connector portion 4B, and a third connector portion 4C, the first connector 4 Terminal 2A of section 4A and terminal 2B of second connector section 4B
To connect the terminal 2C of the third connector portion 4C with the conductive foil 6 of the printed circuit board 5, the second and third connector portions 4
The conductive foil 6 having a pattern bypassing B and 4C must be formed on the pattern forming surface of the printed circuit board 5, and in order to connect the terminals of the respective connector portions 4A, 4B and 4C in this manner, for example, The conductive foil 6 having a pattern as shown in FIG. 12 is required, and the pattern of the conductive foil 6 spreads in the lateral width direction of each of the connector portions 4A to 4C, which causes a problem that it becomes difficult to downsize the device.

Further, as shown in FIG. 13, since the distance between the terminals 2 arranged in two rows in each connector portion 4 is narrow, the conductive foil on the pattern forming surface of the printed board 5 and the terminals 2 penetrating the printed board 5 are also formed. 14 is soldered to the ends of the terminals, a solder bridge 7 as shown in FIG. 14 is generated, and the adjacent terminals 2 are short-circuited by the solder.

Therefore, the present invention has been made to solve the above problems, and it is possible to prevent the conductive foil pattern from expanding and prevent a short circuit due to a solder bridge between adjacent terminals. To aim.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view of a connector portion, FIGS. 2 and 3 are sectional views taken along lines XX 'and YY' of FIG. 1, respectively.
4 to 6 are operation explanatory diagrams.

Since the external structure of the device is almost the same as that of FIG. 7, reference will be made to FIG. 7 in the following description, but when the number of terminals of the connector portion is, for example, eight, as shown in FIGS. In contrast to the connector portion 4 in which four terminals 2 are arranged in two rows in each row, as shown in FIGS. 1 to 3, it is longer than the housing 3 (see FIG. 8) in the left-right direction. In the housing 11, the eight pin-shaped terminals 12 are arranged in a line to form the connector portion 13.

As shown in FIG. 4, the connector portions 13 shown in FIG. 1 are arranged side by side on the resin case 1, and these are temporarily assumed to be a fourth connector portion 13A, a fifth connector portion 13B, and a sixth connector portion 13C. When called, the terminals 12A of the fourth connector portion 13A, the terminals 12B of the fifth connector portion 13B, and the sixth connector portion 13C that are arranged in the direction in which the terminals 12 are arranged, that is, in the direction substantially orthogonal to the lengthwise direction of the housing 11. When connecting the terminals 12C of the above, the terminals 12A, 12B, 12C may be connected by the linear conductive foil 14 formed in advance on the pattern formation surface of the printed board 5.
Similarly, in order to connect the other terminals of the respective connector parts 13A, 13B, 13C, as shown in FIG. 5, a plurality of parallel line-shaped conductive foils 14 are formed on the printed circuit board 5. Often, the conductive foil 14 connects the terminals to each other.

As described above, the plurality of parallel line-shaped conductive foils 14 as shown in FIG.
By connecting terminals arranged in a direction substantially orthogonal to the arrangement direction of the terminals of 13C, it is not necessary to form the conductive foil in a detour pattern as shown in FIGS. Can be prevented.

Further, since the terminals 12 are arranged in a line, the terminals arranged in two lines are not short-circuited by the solder bridge as in the conventional case.

By the way, as shown in FIG. 12, for example, the terminals of the first row of the connector portions 4A to 4C are sequentially a, from the left.
b, c, d, and the terminals in the second row from left to right e, f, g, h
Then, if the same connection state as that shown in FIG. 12 is realized by the conductive foil 14 having a parallel line pattern as shown in FIG. 5, it becomes as shown in FIG.
13C, the terminals are not lined up with a, b, ..., H in order from the left (or from the right).
There is no problem in practical use as long as the correspondence relationship with the terminals of the other connector (not shown) fitted and connected to 3A to 13C is clarified in advance.

Therefore, according to the above-described embodiment, it is possible to prevent the conductive foil pattern from expanding and prevent the device from becoming large in size, and by arranging the terminals in a line, the size of each connector portion in the arranging direction can be reduced. Can be made smaller than the two-row array type of
The size of the device in this direction can be reduced.

Further, reliability can be improved without a short circuit due to a solder bridge between two rows of terminals as in the conventional case.

The number of connector portions and the number of terminals are not limited to those described above, and the present invention can be implemented in the same manner even if the number of connector portions and the number of terminals are other than those described above, and equivalent effects can be obtained. .

The conductive foil may be in the form of a plurality of parallel lines, and its direction is not particularly limited to the direction orthogonal to the direction in which the terminals are arranged as described above.
