Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a printed wiring board connecting device for installing printed wiring boards in parallel and electrically connecting them to each other, for use in television receivers and general electronic equipment. It is something.

2. Description of the Related Art In recent years, in general electronic devices such as television receivers, the structure of printed circuit boards has been simplified with the aim of making them lighter, thinner and more compact. An example of a conventional printed wiring board connecting device will be described below with reference to one drawing.

FIGS. 3 and 4 show a conventional connection device for a rigid printed wiring board. In the case of FIG. 3, it is a convex-concave connector connecting device for connecting a plurality of hard printed wiring boards, and a is a convex connector and b is a concave connector. FIG. 4 shows a state in which a plurality of hard printed wiring boards are connected using this convex-concave connector connecting device.

Reference numeral 4 designates a first hard printed wiring board, to which a concave connector 8 is soldered and fixed, and to a second printed wiring board 6, a convex connector 7 is soldered and fixed to the concave connector 8. This is used to connect a plurality of hard printed wiring boards.

Problems to be Solved by the Invention However, in the above configuration, since an I-type convex-concave connector connection device in which connection terminals are arranged in series is used, it is difficult to connect multiple hard printed wiring boards. When installed in parallel and connected to each other, there are variations in the torsional direction, horizontal tilt direction, front and back position, etc. caused by the mounting angle between the two printed wiring boards, making positioning very difficult. Ta. For this reason, it is necessary to use spacers 9 or separate molded products to position and fix the positions between the hard printed wiring boards, resulting in poor workability and increased man-hours and costs.・For television receivers and general electronic devices that are becoming thinner, parts and patterns can be actually placed on printed wiring boards by using spacers 9 or separate molded products. In view of the above-mentioned problem, the present invention aims to reduce the effective area of printed wiring boards in a board structure in which a plurality of hard printed wiring boards are installed in parallel. The present invention provides a printed wiring board connection device that connects circuits between hard printed wiring boards, securely fixes and holds the mutual positions of hard printed wiring boards, and improves manufacturing accuracy.

Means for Solving the Problems In order to solve the above problems, in the printed wiring board connection device of the present invention, connecting terminals are connected to L-shaped molded products.
They are arranged in a mold, one terminal side is inserted and fixed into a first hard printed wiring board, and a second printed wiring board is connected to the other terminal side and fixedly held.

Function The present invention has the above-described configuration, and when making circuit connections between a plurality of hard printed wiring boards installed in parallel,
By connecting circuits through this L-shaped connection device, the board spacing between parallel hard printed wiring boards is determined by the height of the resin molded product, and furthermore, the upper and lower end surfaces of the resin molded product are Since it contacts the wiring board surface with an L-shaped 9o angle surface, it eliminates variations in manufacturing work such as twisting direction, horizontal tilt direction, front-back position, etc. between boards that occur during installation of the hard printed wiring board. , manufacturing accuracy can be improved.

Further, since there is no need to use spacers or separate molded products for holding the printed wiring boards in fixed positions relative to each other, workability is improved, and man-hours and costs can be reduced.

EXAMPLE Hereinafter, a printed wiring board connecting device according to an example of the present invention will be described with reference to the drawings.

FIG. 1 is an overall perspective view showing an embodiment of the printed circuit board connecting device of the present invention, in which connection terminals 1 are similarly fixed through a resin molded product 2 formed in an L shape and arranged in an L shape. It is something. A is a connecting terminal 1 made into a round shape, and the distance between the hard printed wiring boards is regulated in the height direction of the resin molded product 2. b is a rectangular connecting terminal 1, which more effectively regulates the position between the printed wiring boards in the longitudinal direction of the connecting terminal.

The spacing between printed wiring boards is regulated in the height direction of the resin molded product 2, similar to the connection device shown in a.

An example of the use of the L-shaped printed wiring board connecting device configured as described above will be described below with reference to FIG. 2. FIG. 2 shows an overall perspective view a and a front view when the L-shaped printed wiring board connecting device of this example is used.

In FIG. 2a, 4 is a first rigid printed wiring board, 3 is an L-type connecting device, and 6 is a second printed wiring board.

First, one side of the L-shaped resin molded product of the L-shaped connecting device 3 consisting of the L-shaped resin molded product 2 and the connection terminal 1 is firmly placed on the surface of the first hard printed wiring board 4, and the board terminal hole 10 is penetrated. Fix the connected terminal 1 by soldering. Furthermore, the surface of the second printed circuit board 6 is securely applied to the surface of the L-shaped resin molded product on the other terminal side of the L-shaped connecting device 3, and the connecting terminal 1 passed through the terminal hole 10 of the circuit board is soldered. Fix it.

As described above, according to this embodiment, in a board structure in which a plurality of hard printed wiring boards are installed in parallel, the hard printed wiring boards that adjoin the L-shaped end surfaces of the resin molded product of the L-shaped connecting device By firmly applying and fixing each board to the board surface, it is possible to connect parallel hard printed wiring boards to each other, and
The mutual positions between the hard printed wiring boards can be reliably fixed and regulated.

Effects of the Invention As described above, according to the present invention, when a plurality of hard printed wiring boards are installed in parallel and electrical connections are made,
One terminal side of a connecting device in which connection terminals are arranged in an L shape on a molded product formed in an L shape is inserted and fixed into a first hard printed wiring board, and a second printed wiring board is connected to the other terminal side. By configuring the rigid printed wiring boards to be fixedly held, it is possible to reliably regulate the positions of the hard printed wiring boards, improve manufacturing accuracy, and reduce man-hours and costs.

Furthermore, the usable area of the printed wiring board on which parts and patterns are placed on the printed wiring board is expanded, and the printed wiring board can be used effectively.
