Further, the vertical spacing of the frame material also differs depending on the mounting pitch of various series, and it is designed and manufactured for each series including the members to which terminals and connectors are mounted, and cannot be mounted on a rack case of a different series type.

There were problems such as.

The present invention has been made in view of the above problems, and an object thereof is to provide a terminal board that can be commonly mounted on racks of different series.

[Means for Solving the Problems]

As shown in the principle diagram of FIG. 1, the above problem is caused in a terminal board that is mounted on a cabinet of electronic equipment and collectively mounts input / output connection terminals and connectors. The width and the depth of the rack case where each side length is mounted are obtained by loosely fitting the □ -shaped metal member 2 into the shaped-metal member 1 and using the linear frame member 3 that can freely expand and contract within a predetermined range. The rectangular frame 4 having four sides of the frame member 3 as the sides is formed with the opening surface of the member 1 facing outward so as to match the mounting dimension in the direction.
Two of them are mounted and mounted at a predetermined interval up and down, and terminals and connectors 8 are arranged as bridges between the frame members 3 in the width direction, and a slidable and non-rotating square nut 5 previously inserted in the member 1 and This is solved by the terminal board composed of the expandable frame member of the present invention, which is constructed so as to be fastened and fixed to the tap hole 9 provided on one surface of the member 2.

[Action]

That is, the frame structure has a variable size according to the type of the frame body, and the terminals can be screwed at substantially arbitrary positions between the frame members, thereby achieving the object.

The frame member 3 in which the □ shaped metal member 2 is loosely fitted in the shaped metal member 1 has the longest dimension of any one of the members 1 and 2 as the shortest, and extends with the necessary shortest fitting portion left. It is possible to set the variable length up to the maximum length, and to set an arbitrary length.

Therefore, the frame 4 formed of the frame material 3 can be fitted to the mounting dimensions of all types of rack housings.

Further, the upper and lower two frames 4 are fixed to a mounting mechanism at a predetermined interval for each type of rack case, but this interval can be aggregated into multiple types regardless of the type of rack case. It can be done by providing adjustment means on the fixing metal fittings to the rack case,
As a result, the connection terminals and the connector 8 are attached via the adapter-like attachment member 81 corresponding to the distance,
Therefore, it has versatility to commonly support terminal boards of different types of racks.

Further, in the above-mentioned conventional example, the terminals can be arranged only at predetermined intervals in the width direction of the rack case, but in the present invention, In the portion of the member 1 having the shaped cross section, the square nut 5 inserted can be used to fasten and fix it at an arbitrary position.

Thus, it is possible to provide a terminal board that can be commonly mounted on rack cases of different series types.
