Description

[Detailed Description of the Invention] Industrial Field of Application The present invention provides a method for connecting a connector or connecting terminal section attached to an electronic device, etc. and a connecting terminal section or connector provided on a printed wiring board connected to the connector. The present invention relates to a printed wiring board connecting device that is inserted into a printed wiring board and pulled out from an electronic device, etc., and allows the printed wiring board to assume an electrically connected state similar to that used in the electronic device, etc.

Prior Art In relatively large electronic devices such as videotape radars for broadcasting services, multiple printed wiring boards to which various circuit components are attached are connected to connectors whose connection terminals are fixed to the main body of the electronic device. It is often used by being attached by being inserted into a corresponding item. In such cases, inspections and repairs to maintain the electrical circuits made up of the various circuit components attached to each printed wiring board in proper condition must be carried out only after each printed wiring board is removed from the electronic device. Therefore, when inspecting or repairing each printed wiring board, it is necessary to check the distance between the printed wiring board that has been removed from the connector fixed to the electronic device and the connector fixed to the electronic device. A connecting device is used to make the electrical connection.

Conventionally, as a connection device for such a printed wiring board, for example, a connector is attached to one side of the opposing edge portion of a plate-shaped insulating substrate, and a connection terminal portion is provided on the other side, and these connectors and the connection terminal A connection board has been proposed in which a predetermined printed wiring pattern is formed on the surface of an insulating substrate, and the connection terminal part of the connection board is connected to a connector fixed to the electronic device main body. The connection terminal section of the printed wiring board to be inspected or repaired is then inserted into the connector of the connection board to establish an electrical connection between the printed wiring board to be inspected or repaired and the main body of the electronic device. Ru.

By the way, when the above-mentioned printed wiring board connection device is actually used, the printed wiring board connected to the connection device is mechanically supported by being inserted into the connector of the connection board. Therefore, when the printed wiring board is relatively large or has a relatively large weight, there is a problem that it cannot be supported reliably.

Therefore, as shown in FIG.
is attached and the connection terminal part 1 is attached to the other side.
4 are provided on one surface of the insulating base 11, and a plurality of terminals 15 forming a connecting terminal portion 14 with each of the plurality of terminal pins 13 of the connector 12 are provided.
A printed wiring pattern 16 as shown by dotted lines is provided on both sides of the connecting board 10 sandwiching the connector 12, and is covered with an insulating film.
A pair of support rail members 17 and 18 are connected to the connection board 1
A connecting device is known in which the printed wiring board connected to the connector 12 is supported by the support rail members 17 and 18, which are fixed so as to protrude from the connector 12. Note that the opposite edges 11a and 11 of the insulating base 11 constituting the connection board 10
b is a guide portion that engages with a guide member within the electronic device body when inserted into the electronic device body or the like.

In such a connection device, for example, when the connection terminal portion 2 provided on the printed wiring board 1 as shown by the dashed line in FIG. 5 is inserted into the connector 12, the support rail members 17 and 18 Each of these supports the printed wiring board 1 by engaging with the opposing side edges 3 and 4 of the printed wiring board 1, so that the printed wiring board 1 is reliably supported. However, in this case, one end of each of the support rail members 17 and 18 is fixed to the end of the connection board 10 and protrudes from the connection board 10, resulting in an increase in the size of the entire connection device. This has the disadvantage of causing inconvenience in handling during transportation and storage.

Therefore, in order to alleviate such inconvenience in handling during transportation and storage, a printed wiring board connection device as shown in FIG. 6 has been proposed. This connection device includes a connection board 10 similar to that in the connection device shown in FIG. 5 above, and support rails in the connection device shown in FIG. Support rail members 17' and 18' corresponding to members 17 and 18 are attached to mounting members 19 and 2, respectively.
0, and is configured to be rotatably mounted.

In the connection device shown in FIG. 6, the connector 12 is connected to the connection terminal portion 2 of the printed wiring board 1 as shown by the dashed line in FIG.
When the support rail members 17' and 18' are connected, the support rail members 17' and 18' assume a position protruding from the connection board 10 as shown by solid lines in FIG. 4 to support the printed wiring board 1, and during transportation or storage, etc.
The support rail members 17' and 18' are respectively attached to the mounting member 19 as shown by the dashed lines in FIG.
and 20, and assumes a position where it is folded toward the connector 12 side. By allowing the support rail members 17' and 18' to be folded in this way, the overall size can be reduced during transportation or storage.
It becomes easy to handle.

Problems to be Solved by the Invention However, as described above, the conventional printed wiring board connection device in which the pair of support rail members are made foldable to reduce the overall size, Since each end of the pair of support rail members is pivotally attached to the connection board via the mounting member, the rigidity of the mounting portion of each support rail member to the connection board is reduced, and as a result, the rotation of each support rail member is reduced. As this is repeated, when both support rail members assume the position to support the printed wiring board inserted into the connector, their free ends open apart from each other, causing the opposing edges of the printed wiring board to A problem arises in that the printed wiring board cannot be reliably supported because an appropriate state of engagement with the printed wiring board cannot be obtained.

In view of these points, the present invention is based on two plate-shaped insulating substrates.

Function In the printed wiring board connecting device according to the present invention configured as described above, when a printed wiring board is connected to the connector or the connecting terminal portion, the first and second wiring boards are connected to each other via the connecting member. The second support rail member extends in the direction of extending the connection board, and engages with and supports both side portions of the printed wiring board connected to the connector or the connection terminal portion. The connecting member maintains a constant spacing between the first and second support rail members. Then, the connection board to which the printed wiring board is connected is connected, for example, to an electronic device body to which the printed wiring board is to be installed, through its connection terminal portion or connector, and the connection board between the electronic device body and the printed wiring board is connected. Form an electrical connection.
On the other hand, when the printed wiring board is not connected to the connector or the connection terminal section, the first and second support rail members connected to each other via the connection member are folded to one side of the connection board. ,
