However, in the above-mentioned structure, the design layout, the number of lead wires of the internal wiring in the device structure, and
The layout and processing method become very complicated, and there are some that are close to the limit in terms of assembling, mass production, and cost performance.

In view of these conventional problems, an object of the present invention is to provide a printed wiring board connecting device which is easy to assemble, leads to automation, has mass production and cost advantages, and is very suitable for mass production. To do.

[0008]

In order to solve the above problems, a printed wiring board connecting device of the present invention is provided with a first printed wiring board and a second printed wiring board which are parallel to each other. The three printed wiring boards are configured vertically, and the board-to-board connectors are provided on the above three types of printed wiring boards so that they can be electrically connected. It is provided with a structure for restricting positioning.

[0009]

According to the printed wiring board connecting device of the present invention,
Since it has a lead-to-board connector by leadless, by regulating the positioning by the integrally molded chassis, there is no electrical interference between the lead wire and the electric component unlike the conventional lead connector. ..

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a perspective view of parts in a printed wiring board connecting apparatus according to an embodiment of the present invention. FIG. 2 is a sectional view of the same.

1 and 2, 10 is a mechanism block, 10a is a mechanism, 10b is a printed wiring board in the mechanism block, and 10c is a mounting member. The printed wiring board 10b and the mechanism 10a are fastened to the mounting member 10c with screws 90, respectively. 20
Is an integrally formed chassis, 30 is a main printed wiring board,
40 is a relay printed wiring board, 50 is the plug side of the fixed board-to-board connector, and the main printed wiring board 3
Soldered to 0. Reference numeral 60 denotes a socket side of the fixed board-to-board connector, which is soldered to one of the relay printed wiring boards 40. Reference numeral 70 denotes a socket side of the movable board-to-board connector, which is soldered to the other side of the relay printed wiring board 40. Reference numeral 80 denotes a plug side of the movable board-to-board connector, which is soldered to the printed wiring board 10b in the mechanism block 10.

The assembly sequence will be described below. Relay printed wiring board 40 to main printed wiring board 30
Is electrically connected by inserting and fitting the socket 60 into the plug 50. After that, the bosses 2 are assembled into the integrally molded chassis 20 and a plurality of bosses 2 (not shown in the figure) with screws 90.
Fasten to 0e together with the main printed wiring board 30. At this time, the relay printed wiring board 40a and the integrally formed chassis rib 20b perform positioning in the x direction and prevention of slippage in the y direction. In the z direction, the ribs 20b and 20c of 20-3 and 20-2 regulate the movable socket 70 and the relay printed wiring board 40 with a constant clearance.

Next, the mechanism block 10 is incorporated into the integrally molded chassis 20. At this time, the plug of the movable board-to-board connector 80 is the movable board-to-board connector 70.
The process up to insertion and fitting in the socket will be described.

At the time of insertion, the mechanism block 10 has a plurality of integrally formed chassis (see FIG. 1 for the mechanism hole 10d).
Guided by the guide positioning pin 20a (not shown in the book), the x and y directions are regulated, and then the hole 10e and the guide positioning pin 20d are regulated in the x and y directions in the process of inserting in the z direction. The plug of the movable board-to-board connector 80 is inserted and fitted into the socket of the movable board-to-board connector 70.

Regarding the regulation in the z direction, the integrally molded chassis 20 regulate the positions of the three printed wiring boards. After that, the mechanism block is fastened to the integrally molded chassis 20 with the screw 90. As a connector of the mechanism block 10 to be inserted after one, a movable board-to-board connector that absorbs positional deviation is more suitable in consideration of the cumulative tolerance of each component and the assembly variation.

By the above work assembly, the printed wiring board 10b and the main printed wiring board 30 in the mechanism block are electrically connected.

In the two types of parallel printed wiring boards of this embodiment, the boards are a-sides which are component surfaces and b-sides which are component surfaces.
Although it is a combination with a surface, it may be a combination with a component surface and a foil surface.

[0019]

According to the present invention, by adopting this structure from the lead connector system, there is no troublesome lead processing work, leading to reduction of man-hours, easy assembly, and a device suitable for mass production improvement. To do.
