Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a connection structure between printed boards of an electronic device, which connects two printed boards facing each other at an angle.

FIG. 1 is a front view showing a conventional connection structure between printed boards in this type of electronic device, and in the figure, 1 and 2 are printed boards,
3 is a support metal fitting.

The printed boards 1.2 face each other at an angle of A degree, and are maintained at a distance by a support fitting 3.

A connector 4 is attached to the printed board 1 with its terminals connected to the electrical circuit configured on the printed board 1, and a connector 5 is attached to the printed board 2 to connect its terminals to the electrical circuit configured on the printed board 2. It is connected and installed.

Print 1 to boards 1 and 2 are connected by plugging connectors 7 and 8 connected to both ends of cable 6 into connectors 4 and 5, respectively.

In such a conventional connection structure, the connectors and cables protrude from the top of the device, front and back, so it was inevitable that the device would become larger.

The present invention is intended to solve the above-mentioned problems, and aims to provide a connection structure between printed boards that can remotely reduce the size of the device.

Next, an embodiment of the present invention will be described with reference to FIGS. 2 and 3.

Fig. 2 is a front view showing an embodiment of the printed board connection structure according to the present invention, and Fig. 3 is a detailed perspective view of the main parts.
1 is a spacer, 12 is a first connector, and 13 is a second connector.

The spacer 11 faces the upper and lower surfaces of the printed boards 1 and 2 at the same angle, and is mounted on the printed board 2 by screws (not shown) inserted into the mounting holes 14.

This spacer 11 has a hole 15 for attaching the connector 12 and a number of holes (openings) 16 for inserting the terminals of the connector 12.
However, instead of a large number of holes 16, one opening 17 having a size that includes these holes may be formed.

The connector 12 has a large number of terminals 18, as shown in detail in FIG. It is attached to the spacer 11 by inserting it into the hole 15 of the spacer 11, fitting the spring washer 21 onto the screw 19, and screwing and tightening the nut 22.

After the connector 12 is attached, the insertion portion of the terminal 18 into the through hole of the printed board 2 is soldered.

The connector 13 has a large number of terminals 23, and is attached to the printed board 1 with screws by inserting the terminals 23 into through holes of the printed board 1.

After the connector 13 is attached, the insertion portion of the terminal 23 into the through hole of the presto board 1 is soldered.

Assembly of the electronic device is performed as follows.

That is, the connector 13 is plug-in connected to the connector 12, and the support fitting 3 fixed to the IJ-)) board 2 and the printed board 1 are connected with screws to complete the device assembly, and the printed boards 1 and 2 are connected. be done.

This assembly and connection work is extremely easy, and since connectors and cables do not protrude as in the conventional case shown in FIG. 1, the device can be made more compact.

In the above description, an example using the support metal fitting 3 has been described, but instead of using the support metal fitting 3, a connection structure consisting of a spacer and a connector may also be adopted on the left side of the support metal fitting 3 in FIG. In this case, the two printed circuit boards can be connected by simply connecting the connectors at both ends of the two printed circuit boards, thereby making the connection work even easier.

As described above, according to the present invention, both printed boards can be assembled and connected using a spacer with an inclined surface and a normal type connector, which simplifies the structure and reduces the connection work. It can be simplified, and since there is no longer anything protruding from the top of the printed board front to back, it has various excellent effects such as making it possible to make the device more compact.

[Brief explanation of drawings]

FIG. 1 is a front view of a conventional connection structure between printed boards, FIG. 2 is a front view showing an embodiment of the connection structure between printed boards according to the present invention, and FIG. 3 is an exploded perspective view of the main parts. Inside, 3 is a support fitting, 11 is a spacer, 12 is a first connector, 13 is a second connector, 16 is a hole (opening), 17 is an opening,
18.23 is a terminal, and 19 is a screw.

Claims (1)

[Scope of utility model registration request] In an electronic device formed by connecting two printed boards that face each other at an angle, a spacer is mounted on one of the printed boards, the upper and lower surfaces of which are at the same angle as both of the printed boards, and which has openings for terminal insertion. , a first connector is attached to the upper surface of the spacer by passing its terminal through the opening and connecting to a through hole of one of the printed boards, and a first connector is attached to the other printed board facing the one of the printed boards. A second connector for connecting to the first connector is attached to the surface by connecting its terminal to a through hole of the other printed board, and the both printed boards are connected to each other through the first and second connectors. A connection structure between printed boards, which is characterized by being able to connect boards.
