  The foot part 3 is provided so as to extend from a part of the plate-like part 2 to the substrate 20 side in a state where the plate-like part 2 presses the locking part 11. The foot part 3 may be provided so as to extend obliquely with respect to the flat part 2a. Since the foot part 3 is provided so as to extend obliquely with respect to the flat part 2 a, even if there is a tall part 21 in the vicinity of the locking part 11, the plate-like part 2 does not contact the part 21. The locking part 11 can be pressed.

  Further, for example, the foot 3 may be provided such that the angle with respect to the flat surface 2a can be adjusted by fixing the foot 3 with a screw 5 at a position extending obliquely with respect to the flat surface 2a. The angle of the foot portion 3 with respect to the flat surface portion 2a can be adjusted in accordance with the height of the back of the component 21 arranged in the vicinity of the locking portion 11.

  The foot part 3 may include at least two foot members 3a. In this case, the at least two foot members 3a may be arranged so as to sandwich the locking portion 11 therebetween. In one embodiment of the present invention, two foot members 3a are attached with screws 5 on both sides of one end of the flat portion 2a.

In this case, the interval between the notches 13 is provided in accordance with the interval between the feet 3.

  For example, the width of the notch 13 may be formed to about 3 mm. In this case, the width of the foot 3 is smaller than the width of the notch 13. The hook portion 4 is formed in an L shape having a protrusion of about 2 mm on the substrate 20 side. Further, the angle between the foot part 3 and the plate-like part 2 is preferably about 15 ° because it is easy to insert.

  Next, the operation of the substrate removal jig and the substrate removal mechanism including the same according to an embodiment of the present invention will be described.

  First, a method for attaching the substrate 20 will be described with reference to FIG. The substrate 20 is moved to the front end side of the locking portion 11 while the locking portion 11 is pressed at the end portion of the substrate 20 by aligning the substrate 20 with the inside of the wall member 12 of the housing 10. When the substrate 20 moves until it exceeds the tip of the locking portion 11, it returns to the position before the locking portion 11 is pressed by the elastic force, and the substrate 20 is locked by the locking portion 11.

  Next, a method for removing the substrate 20 will be described. By using the substrate removal jig 1, the substrate 20 is removed from the housing 10 in the procedure shown in FIGS.

  With reference to FIG. 2, the substrate 20 is locked to the housing 10 by the locking portion 11. A tall component 21 is mounted on the substrate 20 in the vicinity of the locking portion 11. In this state, the foot 3 of the board removal jig 1 is inserted into the notch 13 of the housing 10 from the inside of the housing 10, but the plate-like portion 2 is not in contact with the locking portion 11. The hook portion 4 is not in contact with the other surface 20b of the substrate 20.

  Since the tall component 21 is disposed in the vicinity of the locking portion 11, the angle between the foot portion 3 and the plate-like portion 2 is adjusted so that the plate-like portion 2 does not contact the component 21. In this state, the board removing jig 1 is passed between the housing 10 and the component 21, and the foot 3 is inserted into the notch 13 formed so as to sandwich the locking part 11.

  With reference to FIG. 3, subsequently, the foot 3 and the hook 4 are inserted into the notch 13 formed so as to sandwich the locking portion 11, and the hook 4 is hooked on the other surface 20 b of the substrate 20. Further, the curved surface 7 of the plate-like portion 2 comes into contact with the locking portion 11.

  With reference to FIG. 4, subsequently, the locking portion 11 is separated from the end portion of the substrate 20 by pressing the locking portion 11 of the housing 10 with the curved surface 7 of the plate-like portion 2. Thus, the latching portion 11 is released from the one surface 20 a of the substrate 20, so that the latching by the latching portion 11 is released.

  At this time, the point where the force is applied to the plate-like part 2 becomes the force point, the contact point 14 between the other surface 20b of the substrate 20 and the hook part 4 becomes a fulcrum, and the curved surface 7 of the plate-like part 2 and the locking part 11 The contact 15 serves as an action point. That is, in accordance with the lever principle, by using the substrate removal jig 1, it is possible to push the locking portion 11 with a smaller force than to push the locking portion 11 directly.

  At this time, since the portion that presses the locking portion 11 of the plate-like portion 2 pushes while sliding the locking portion 11, the portion that presses the locking portion 11 of the plate-like portion 2 is a smooth curved surface 7, It is possible to reduce scratches when the locking portion 11 is pushed. By reducing the damage to the locking portion 11, the number of times the casing 10 is reused can be increased.

  By lifting the other surface 20 b of the substrate 20 with the hook portion 4, the substrate 20 is lifted from the housing 10 and removed. By these operations, even when a tall component 21 is arranged in the vicinity of the locking portion 11, the board removal jig 1 can be adjusted by adjusting the angle between the plate-like portion 2 and the foot portion 3. The substrate 20 can be removed from the housing 10 without touching 21.

  In addition, although the case where the board | substrate removal jig | tool 1 is not used was demonstrated about the attachment method of the board | substrate 20 above, the board | substrate 20 may be attached to the housing | casing 10 using the board | substrate removal jig | tool 1. FIG. In this case, the board 20 is aligned with the inside of the wall member 12 of the housing 10, and the foot 3 of the board removal jig 1 is locked by the plate-like portion 2 with the notch 13 of the housing 10 being inserted. The part 11 is pressed.

  When the latching portion 11 is pressed by the plate-like portion 2, the substrate 20 is fitted into the latching portion 11 without any load. When the substrate 20 is fitted to a position beyond the tip of the locking portion 11, the locking portion 11 is returned to the position before the locking portion 11 is pressed by the elastic force, and the substrate 20 is locked by the locking portion 11. After being locked, the substrate removal jig 1 is pulled out.

  By attaching the substrate 20 to the housing 10 using the substrate removal jig 1, compared with the case where the substrate removal jig 1 is not used, the substrate 20 does not press the locking portion 11. Can be prevented from being damaged. Moreover, since the latching | locking part 11 is not pressed by the edge part of the board | substrate 20, it can prevent that the surface of the latching | locking part 11 gets damaged.

Next, the function and effect of the embodiment of the present invention will be described.

For this reason, by using the contact point 14 between the hook part 4 and the other surface 20b as a fulcrum and the contact point 15 between the plate-like part 2 and the locking part 11 as an action point, the locking part 11 is pushed on the principle of the lever. The locking portion 11 can be removed from the one surface 20a of the 20. Accordingly, the locking portion 11 can be removed from the one surface 20a of the substrate 20 by pressing the locking portion 11 with a smaller force than when directly pressing with a finger or the like.

  Therefore, it is easy to adjust so as to push the locking portion 11 within the minimum necessary range. Therefore, it is possible to prevent the locking portion 11 from being deformed more than necessary. In addition, it is possible to suppress the substrate 20 or the component 21 from being accidentally damaged by applying an excessive force. Furthermore, since it is possible to prevent the locking portion 11 from being deformed more than necessary and to damage the substrate 20 or the component 21, the removal work is facilitated, so that the work time for removal can be shortened.

  According to the substrate removal jig 1 of one embodiment of the present invention, the plate-like portion 2 includes the flat portion 2a facing the locking portion 11 in a state where the plate-like portion 2 presses the locking portion 11. Since the foot portion 3 is provided so as to extend obliquely with respect to the flat surface portion 2a, the foot portion 3 and the hook portion 4 can be brought into contact with the substrate 20 without greatly tilting the plate-like portion 2. For this reason, even when the tall component 21 is disposed in the vicinity of the locking portion 11, the hook portion 4 is put on the other surface 20 b of the substrate 20 without bringing the substrate removal jig 1 into contact with the component 21. Thus, the locking portion 11 can be pushed by the plate-like portion 2. For this reason, the board | substrate 20 can be removed, without damaging the components 21 by contacting with the board | substrate removal jig | tool 1. FIG.

  According to the board removing jig 1 of one embodiment of the present invention, the foot 3 is provided so that the angle with respect to the flat surface 2a can be adjusted. The angle can be adjusted according to the height of the back. For this reason, the board | substrate 20 with which the component 21 of the wide range was mounted can be removed, without damaging the board | substrate 20 or the component 21. FIG.

  According to the substrate removal jig 1 of one embodiment of the present invention, the portion of the plate-like portion 2 that presses the locking portion 11 is the curved surface 7, so that when the locking portion 11 is pressed, It can reduce that the latching part 11 is damaged by the part which presses the latching | locking part 11 of the part 2 pushing the latching part 11 sliding. Moreover, the number of times the casing 10 is reused as it is can be increased by reducing the damage to the locking portion 11.

  According to the substrate removing jig 1 of one embodiment of the present invention, the foot portion 3 includes at least two foot members 3a arranged so as to sandwich the locking portion 11 therebetween, and the hook portion 4 includes at least 2 It includes a plurality of hook members 4a provided at the tips of the two leg members 3a. For this reason, the force added to the board | substrate 20 can be disperse | distributed by pressing the board | substrate 20 with the some leg member 3a and the hook member 4a. Therefore, the substrate 20 can be removed stably. Moreover, since the board | substrate 20 is lifted in several places, the board | substrate 20 can be lifted easily. Moreover, since the force applied to the substrate 20 can be dispersed, the substrate 20 can be prevented from being damaged.

  According to the substrate attachment / detachment mechanism 100 of one embodiment of the present invention, the substrate removal jig 1 for detaching the substrate 20 from the housing 10 by removing the locking portion 11 from the housing 10 and the one surface 20a.
