Abstract

(57) [Summary] [Structure] The main printed circuit board 1 and the sub printed circuit board 2 are
The connectors 5, 6 and 7, 8 are used by being coupled so as to be parallel to each other. Screw holes 3 are formed in the sub printed circuit board 2 at two locations near the connectors 5 and 7, and the screw holes 3 are formed on the surface of the main printed circuit board 1 facing the sub printed circuit board 2 at positions corresponding to the screw holes 3, respectively. A support 4 is provided. By inserting a separation screw into the screw hole 3 and rotating it, the fitting of the connector is pulled out and the two printed circuit boards are separated. [Effect] Even when the number of pins of the connector increases and it is not easy to pull it out manually, the printed board can be easily separated without fear of being damaged.

[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed circuit board separation structure, and more particularly, to a printed circuit board separation structure used by connecting them in parallel with each other by a connector.

[0002]

[Prior Art]

 One of the methods of mounting components on a printed circuit board is to use a small sub printed circuit board mounted in parallel on a main printed circuit board via a connector. In such a case, when disconnecting the connector and removing the sub printed circuit board, the larger main printed circuit board is conventionally fixed by some method and the end of the small sub printed circuit board is held by hand. It was separated by pulling it so as to pull out the fitting.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional method, when the number of pins of the connector is small, it is a simple method and there is no problem, but when the number of pins of the connector increases and the fitting force of the connector becomes stronger, it becomes difficult to pull out by hand. Since a large force acts on the printed circuit board in the vertical direction, the printed circuit board may be damaged.

An object of the present invention is to provide a structure for separating a printed circuit board that can be easily separated without damaging the printed circuit board even if the number of pins of the connector increases.

[0005]

[Means for Solving the Problems]

 The printed circuit board separation structure of the present invention is a printed circuit board separation structure for separating two printed circuit boards to be used by connecting them in parallel with each other by a connector provided on the printed circuit board. A screw hole that penetrates the printed circuit board is provided near the connector of the printed circuit board of No. 2, and the pressure of the screw tip is applied to the position of the other printed circuit board that faces the one printed circuit board facing the screw hole. It is characterized by having a support to receive.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an external view showing an embodiment of the present invention.

In this embodiment, as shown in FIG. 1, the main printed circuit board 1 and the sub printed circuit board 2 are used by being connected by connectors 5, 6 and 7, 8 in parallel with each other. .. The sub printed circuit board 2 has screw holes 3 formed at two locations near the connectors 5 and 7, and the main printed circuit board 1 has a position corresponding to the screw hole 3 on the surface facing the sub printed circuit board 2. , Each of which is provided with a support 4.

FIG. 2 is a partial cross-sectional view for explaining the separating operation of the embodiment shown in FIG. FIG. 2A shows a state in which the main printed circuit board 1 and the sub printed circuit board 2 are connected by the connectors 5 and 6. When the separating screw 9 is inserted into the screw hole 3 and rotated, the tip of the separating screw 9 comes into contact with the support 4. When the separating screw 9 is further rotated and inserted continuously, a force is applied in the direction of separating the connectors 5 and 6, so that the main print board 1 and the sub print board 2 can be easily attached as shown in FIG. 2B. Is separated into

When the connectors are connected at two places as in the present embodiment, it is preferable to use two separating screws to uniformly apply force to the two connectors to separate them.

[0011]

[Effect of the device]

 As described above, according to the printed circuit board separation structure of the present invention, the number of pins of the connector is increased by using the screw holes formed in the one printed circuit board and the supports attached to the other printed circuit board. Even if the fitting force increases, the printed circuit board can be easily separated without damage.
