Is a sectional view of the same. As shown in FIG. 3, the board mounting clip 1 includes a holder 2, a rotating member 3, a spring guide pin 4, a spring 5, and members of the rotating member 3, and rotating shafts 6 and 7 of the spring guide pin 4.

These members used for the substrate mounting clip 1 may be made of any material suitable for being immersed in the plating solution. In this embodiment, a stainless steel member, which is optimal, is used.

The holder 2 is formed by bending a stainless steel plate into a U-shape, and has a notch 9 near the bottom surface 8 for inserting a substrate. The arrows in FIGS. 1 and 3 indicate the direction in which the substrate is inserted. In FIG. 1, reference numeral 9 denotes a substrate guide tongue. According to the embodiment, the substrate holding portion 23 has a flat plate shape, but may have a gear tooth shape.

Reference numeral 10 denotes a mounting piece to be attached to a substrate holding frame (not shown). Since the mounting piece 10 of the embodiment is used by being attached to a flat plate portion of the substrate holding frame, as shown in FIG. However, the mounting piece 10 is formed linearly when it is bent so as to open outward at a right angle.

The rotating member 3 includes a substrate holding portion 13 having gear-shaped teeth and a lever 1 protruding outward from the holder 2.
4, a stopper piece 15 and a spring mounting portion 16 are formed. The substrate holding portion 13 is formed wide at a position far from the rotation shaft 6, and the release position on the right side in the rotation direction (upper left position of the substrate holding portion 13 in FIG. 3) is the substrate opening portion 1.
7 is formed narrow at a short distance from the rotation shaft 6.

The rotating member 3 is rotatably mounted on a rotating shaft 6 extending between the holder side walls 11 and 12. Although the substrate pressing portion 13 of the rotating member 3 in the embodiment has gear-shaped teeth formed thereon, it is not limited to this as in the first invention.

The cross-sectional shape of the gear-shaped teeth in the embodiment of the substrate holding portion 13 is a mountain shape, and the thickness of the gear-shaped teeth is about 4 mm. Note that the thickness of the gear-shaped teeth may be appropriately selected, and the cross-sectional shape is also arbitrary.

The substrate pressing portion 13 of the rotating member 3 is narrowed to a distance capable of holding the substrate in opposition to the substrate pressing portion 23 of the holder 2 as shown in FIG. 5 when the substrate is pressed, and is shown in FIG. The substrate opening part 17 faces the substrate pressing part 23 of the holder 2 and the space between them is widened.

By operating the lever 14 of the rotating member 3 protruding outward from the holder 2, the rotating member rotates about the rotating shaft 6, and the substrate pressing portion 13 contacts the substrate pressing portion 23 of the holder 2. Contact and separate.

The turning member 3 is urged in the turning direction.
The stopper piece 15 is regulated so as to be able to stop at the substrate fixing position and the substrate releasing position. The spring 5 biases the rotating member 3, and the spring 5 is mounted between the spring guide pin 4 and the spring mounting portion 16 of the rotating member 3. The spring guide pin 4 is rotatably mounted on the rotating shaft 7.

Hereinafter, a method of using the board mounting clip 1 will be described with reference to FIGS. When the lever 14 is rotated to the left in the drawing as shown in FIG. 4, the rotating member 3 is also rotated to the left. Until the stopper piece 15 comes into contact with the spring guide pin 7, the rotation is continued under the urging of the spring 5, the rotation is stopped by the spring guide pin 7, and the stopper is stopped.

At this time, the substrate pressing portion 13 of the rotating member 3 retreats to the right in the drawing, and the interval between the rotating member 3, the substrate guide tongue piece 9 and the substrate pressing portion 23 of the holder 2 is widened. This state is a state before the board is inserted and a state when the board is removed.

In this state, the board is inserted between the board guide tongue piece 9 and the rotating member 3. Thereafter, as shown in FIG. 5, the lever 14 is rotated rightward in the figure. At the same time, the rotating member 3 also rotates to the right, and the stopper piece 16 is
Until the spring 5 comes into contact with it, the rotation is continued, and the rotation is stopped by the bottom surface 8 to stand still. At this time, the substrate pressing portion 13 of the rotating member 3 faces the substrate pressing portion 23 of the holder 2, the distance between them is reduced, and the substrate can be sandwiched.

The board mounting clip 1 in the embodiment shown in FIG.
Although an example in which a substrate is inserted from the left in the drawing is illustrated, when the substrate is used in a substrate holding frame, it may be attached to the top, bottom, left, and right of the substrate holding frame. In either case, it can be used by changing the mounting direction.

[0022]

According to the present invention, a holder has a substrate holding portion, a rotating member is provided with a substrate holding portion and a substrate opening portion, and a lever protruding outward from the holder is formed. Is operated to rotate and hold the substrate about the rotation axis, thereby holding and releasing the substrate. Therefore, the substrate can be attached to the substrate holding frame by a simple operation.

According to the third aspect of the present invention, since the rotating member is urged in the rotating direction and is regulated so as to be able to be stopped by the stopper at the substrate fixing position and the substrate releasing position, the substrate is restricted. In the case of mounting and removing the work, the work can be performed by releasing the hand from the board mounting clip, and the work efficiency can be improved.
