Description

[Detailed Description of the Invention] This invention relates to a rack for printed wiring boards.

Printed wiring boards, in which electrical circuits are formed on an insulating substrate by methods such as printing, have come to be used in large quantities and widely with the rapid advancement of electronics, and are now being used in all industrial fields. It is reaching. Printed wiring boards of various sizes are used depending on these various uses.

Printed wiring boards, which are used in large quantities in this way, have so far been made of a roughly rectangular parallelepiped frame with a pair of side walls facing each other, each having a large number of folds.
A large number of printed wiring boards were stored in an upright position by sandwiching both ends of the board between the folds. However, such racks can only accommodate printed wiring boards of a certain size, and as mentioned above, storing printed wiring boards of various sizes requires a large number of racks according to the size, which is extremely expensive. It was uneconomical.

This invention was made under these circumstances, and the object is to provide a printed wiring board storage rack that can store printed wiring boards of any size.

That is, the printed wiring board storage rack of this invention is a printed wiring board storage rack consisting of a substantially rectangular parallelepiped frame, and one opposing side surface of the frame is provided with a large number of parallel folds, all of which extend perpendicularly. are provided facing each other, and a large number of locking protrusions are provided facing each other in two rows, upper and lower, at regular intervals on the other opposing side surface, and one of the opposing folds is fixed to a frame, The other side is provided with an upper locking arm and a lower locking arm that extend horizontally, and these locking arms are removably fitted into the locking protrusion, and the printed wiring board has both ends thereof It is characterized in that it is supported in an upright state by engaging with mutually corresponding recesses of the opposing pleats.

This invention will be explained in more detail below with reference to the drawings.

FIG. 1 is a perspective view showing an example of the printed wiring board storage rack of this invention. In Figure 1,
On one side of the frame body 1 there is a fixed fold body 2 which is attached to the frame body 1 . The fixed fold body 2 is made up of a substantially rectangular frame body and a large number of vertical bars attached at regular intervals. Alternatively, the fixed fold body 2 may be a plate with a number of vertical grooves formed therein. Two supports 3 are attached to the upper and lower sides of the frame 1 on opposing side surfaces adjacent to the side surfaces to which the fixed folds 2 are attached. A large number of U-shaped locking protrusions 4 are fixed to the upper surface of these supports 3 at predetermined intervals. Note that the four locking protrusions located in corresponding positions on the top and bottom and left and right form one set, and the following 1
Supports two movable folds.

FIG. 2 is a front view of the movable fold body, which includes a pair of upper and lower locking arms 5, 6 and a number of vertical bars 7 connecting them. This movable folded body is supported by the frame 1 at a desired position so as to face the fixed folded body 2 by fitting the upper and lower locking arms 5 and 6 into a predetermined pair of locking protrusions 4. be done.
FIG. 3 shows how the locking arm 5 fits into the locking protrusion 4. In this way, the movable fold body is supported vertically in the desired position where the locking projection 4 is present. Note that the movable fold body is not limited to the structure shown in FIG. 2, but may be one in which upper and lower locking arms are attached to the upper and lower ends of a plate body in which a large number of vertical grooves are formed.

As explained above, according to the printed board storage rack of this invention, it is possible to select the position of the movable fold body according to the dimensions of the printed wiring boards to be stored, so it is possible to store printed wiring boards of various sizes. It can be stored. Therefore, there is no need to prepare a large number of storage racks according to the size of the printed wiring boards, and one storage rack according to the present invention can accommodate all printed wiring boards, which is very economical. Furthermore, the position of the movable folds can be quickly changed with a single touch, and handling is very convenient.
