JPH06262542A - Substrate inserter - Google Patents

Abstract

PURPOSE:To secure a substrate inserter easy to insert a substrate into a card box and to extract this substrate inserter with one hand alone by installing a slide mechanism, where a pushing fitting slides on a stationary fitting when a handle part is pulled nearer to an arm part, and a reset spring of the stationary fitting, respectively. CONSTITUTION:If a handle part 2 is not grasped tight, a substrate inserter is easily inserted into an inner part of the card box as an interval between two stationary fittings 1 is narrower than that of a flange 9a of a card box 9. If the center of this handle part 2 is grasped by one hand, an interval between these stationary fittings 1 and 1 is widened with work of a slide part 8, and thereby the stationary fitting 1 is engaged and held by the flange 9a of the card box 9, and if it is further grasped tight, a pushing fitting 4 is advanced forward, pushing both ends of a substrate 10 thereinto with uniform force, and this substrate 10 is surely inserted thereinto. After insertion, if force is loosed, the stationary fitting 1 is put back to the original position by dint of spring action, and since the interval becomes narrowed again, the substrate inserter is easily extractable from the car box 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board insertion tool used when mounting a board in a card box, and more particularly to a board insertion tool used when a large insertion force is required.

[0002]

2. Description of the Related Art An example of a conventional board insertion tool is shown in FIG. In the figure, it has a structure including a fixing metal fitting 1 ', a grip portion 2, springs 3a and 3b, a pushing metal fitting 4, a cover 5, an arm portion 6, and a pin 7.

Since the fixing metal fitting 1a is supported by the pin 7, it has a structure in which it can freely move about the pin 7 in the direction of the arrow shown in FIG.

Therefore, the board insertion tool is installed in the card box 9
It can be easily inserted inside the flange (9a). Further, due to the action of the spring 3a, the fixing metal fitting 1'is
Since it is returned to the original position, the fixing metal fitting 1'is engaged and held by the flange portion 9a of the card box. Here, since the two push-in fittings 4 are connected by the grip portion 2, when the central portion of the grip portion 2 is gripped and tightened, the push-in fitting 4 moves forward and pushes both ends of the board 10, so that the board 10
Is definitely inserted.

[0005]

With this conventional board insert, in order to remove the board insert held by the flange portion of the card box after insertion, while holding the board insert with one hand, the other It is necessary to forcibly move the fixing bracket 1 in the direction of the arrow shown in FIG. 4 by hand, and a series of operations from the insertion of the board insertion tool into the card box to the board insertion step and then the board insertion tool removal. Since the operation cannot be performed with only one hand, the workability is extremely poor.

[0006]

The board insertion tool of the present invention comprises:
The sliding part 8 of the fixing metal fitting 1 has a tapered structure. By gripping the grip portion 2 with such a structure, the interval between the two fixing metal fittings 1 is widened, the fixing metal fitting 1 is held by the flange portion 9a of the card box, and when the force is loosened, the fixing metal fitting 1 is fixed. Is returned to its original position by the action of the spring 3, and the gap between the two fixing metal fittings 1 is narrowed, so that the board insertion tool can be easily removed from the card box.

[0007]

The present invention will be described below with reference to the drawings. 1 is a perspective view showing an embodiment of the present invention.
3 and FIG. 3 are plan views showing an embodiment in which the cover 5 of FIG. 1 is removed. The fixing metal fitting 1 is inserted into the card box 9 and the fixing metal fitting 1 is inserted into the card box 9 respectively.
The state where the substrate 10 is inserted by engaging with the flange portion 9a of FIG.

In FIG. 2, since the distance between the two fixing metal fittings 1 is narrower than the distance between the flange portions 9a of the card box 9 when the grip portion is not gripped, the board insertion tool can be easily inserted into the card box. Can be plugged inside 9. Here, the two fixing fittings 1 are the grip portions 2
Since they are connected to both ends of the handle part 2 by gripping the central part of the handle part 2 with one hand, the gap between the two fixing brackets 1 is widened by the action of the slide part 8 shown in the figure, and the flange part of the card box is expanded. The fixing metal fitting 1 is engaged with and held by 9. Further, when the grip portion 2 is firmly gripped, the push-in fitting 4 advances and pushes both ends of the substrate 10 with equal force, so that the substrate 10 is reliably inserted.

When the force is loosened after the board 10 is inserted, the fixing metal fitting 1 is returned to its original position by the action of the spring 3, and the distance between the two fixing metal fittings 1 is narrowed again. It can be easily removed from the card box 9.

[0010]

As described above, according to the present invention, when a board is mounted in a card box, a series of operations from insertion of the board insertion tool in the card box to the removal of the board insertion tool after the step of board insertion is performed. There is an effect that it can be performed reliably and easily.
