Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a board holder useful for electronic devices having multiple replaceable printed circuit boards.

BACKGROUND OF THE INVENTION In electronic devices equipped with a large number of replaceable printed circuit boards, the printed circuit boards are often placed close to each other and arranged side by side, as shown in FIG. 5, for example, from the standpoint of space. In FIG. 5, 25 is a cabinet. 26 and 27 are connectors provided within the cabinet 25 for coupling with connectors provided on the printed circuit board. 28 and 29 are kite rails provided in the cabinet 25 for holding printed circuit boards.

By the way, when inspecting or repairing a printed circuit board inside the device, it is desirable to do so with the printed circuit board (hereinafter referred to as the board to be inspected) attached, but as mentioned above, each printed circuit board should be close to each other. Since the board to be tested is lined up in parallel, it is difficult to apply the probe of the tester to the electronic components on the board to be tested, or to adjust adjustable parts (variable capacitors, variable resistors, etc.) on the board. The task of doing so is difficult. Therefore, as shown in FIG. 5, it is conceivable to use an inspection spacer 30 made of a printed circuit board similar to the above-mentioned board to be inspected. The spacer 30 has a connector (
(not shown in the figure), and each has a connector 31 at the other end that connects to a connector provided on the board to be inspected.
The surface has conductive patterns that connect the terminals of the connectors at both ends.

Problems to be Solved by the Invention However, in the above configuration, the board to be tested is held only by the bonding force of the connector, and if the board to be tested is made of, for example, glass epoxy material or has heavy parts, If the connector is quite heavy, a considerable force will be applied to the connector, and in some cases, there is a possibility that the connector will be damaged. In addition, since the board to be tested is made to protrude outward from the cabinet by inserting a spacer, workers performing inspections and repairs must be careful not to wobble the board to be tested or disconnect connectors. , which was extremely difficult to work with.

SUMMARY OF THE INVENTION An object of the present invention is to provide a board holder for an electronic device that makes it possible to test a printed circuit board without applying excessive force to a connector.

Means for Solving the Problems In order to solve the above problems, the present invention provides a spacer attached to a cabinet with a support member for supporting a substrate to be inspected.

Operation With the above configuration, the support member supports the substrate to be inspected, the weight of the substrate to be inspected is received by the cabinet via the spacer, and the substrate to be inspected is stably held.

EXAMPLE Hereinafter, an example of a substrate holder for an electronic device according to the present invention will be described based on the drawings. FIG. 1 is a perspective view of the present board holder. In FIG. 1, 1 is a spacer, which is made of a glass epoxy printed circuit board and has the same shape and size as a formal board constituting an electronic device. There is. 2 is a connector that connects with the connector on the cabinet side,
3 is a connector that is coupled to a connector on the board to be inspected.

A conductive foil 4 connects each terminal of the connector 2 and the connector 3. Reference numeral 5 denotes a support member for supporting the board to be inspected, which is configured in an L-shape and is fixed to the corner of the board 1 by a cut-and-raised part 6 provided at the corner. 7 is a screw for fixing the support member. A take-out lever 8 is provided so that it can be easily removed when removing the support member 5, and is rotatably attached to the tip of the short side portion 9 of the support member 5 with a rotation pin 10. Reference numeral 11 denotes a guide rail attached to the long side portion 12 of the support member 5. Reference numeral 13 denotes a handle portion formed at the tip of the long side of the support member 5 by bending.

FIG. 2 is a perspective view showing the substrate holder inserted into the cabinet. The board holder is inserted into a part of the cabinet where the board to be inspected is accommodated, and the connector 2 and the connector 14 on the cabinet side are connected. In this state, the short side 9 of the support member 5 hits the front surface 20 of the cabinet.

3 and 4 show the state in which the board to be inspected is mounted. In FIGS. 3 and 4, the substrate to be inspected 1
5 is placed on the guide rail 11 of the support member 5, and the connector 16 on the board to be tested side is connected to the connector 3 of the test tool. Inspection and repair work is performed in this way
5 can be carried out while being firmly supported by the support member 5, the operator does not have to worry about wobbling of the board 15 to be inspected or disconnection of the connector, etc., making the work very easy. Furthermore, as mentioned above, the short side 9 of the support member 5 is in contact with the front surface 20 of the cabinet, so
A portion of the weight of the substrate to be inspected 15 on the long side portion 12 of the support member 5 is supported by the front surface portion 20 of the cabinet.

17 is a lever for removing the board 15 to be inspected;
It is rotatably attached to a corner portion of the substrate 15 to be inspected by a rotary pin 10 . When removing the board 15 to be inspected, the lever 17 is pulled in the direction of arrow A. Then,
Since one tip of the lever 17 hits and pushes the support member 5, the connector 16 and the connector 3 can be separated very easily. Further, when removing the main board holder, the lever 8 is pulled in the direction of arrow B. Then, the tip of the lever 8 comes into contact with the front surface 20 of the cabinet and pushes it, making it possible to separate the connector 2 and the connector 14 very easily.

Effects of the Invention As described above, in the present invention, by providing a support member that supports the board to be inspected, the support member supports the board to be inspected from below, and the board to be inspected protrudes from the cabinet to the outside. Even if the test board cannot be held by the printed circuit board holding guide rails in the cabinet, the test board is stably held by the support member, and no undue force is applied to the connector.

In addition, the inspection and repair workers do not have to worry about wobbling of the board to be inspected or disconnection of the connector, etc., making the work extremely easy and having great practical effects.
