(4) The switch can be firmly fixed to the panel even though the switch can be easily mounted and removed from the panel.
(5) It can be applied to a nut-mounted switch in which a thread is provided on a conventional switch, and there is no need to change the shape of the conventional switch.

  The switch mounting tool to the panel of the present invention is provided with a thread on the circumferential part of the outer surface of the switch and a keyway on a vertical part of the outer surface of the switch, and is formed on the inner surface to be fitted to the thread. A fixing tool provided with a fastening protrusion having a mounting protrusion, a rotation-preventing protrusion formed on the inner surface that fits in the key groove, and a mounting guide groove formed in a direction perpendicular to the outer surface, and a guide protrusion formed on the inner surface And a fastening groove formed with a taper surface that protrudes in the circumferential direction, and a fastening tool that attaches and detaches the fixing tool to and from the switch. The mounting tool and the fastening tool are connected to the mounting guide groove. The unit is configured to be loosely fitted to operate the fastening tool.

  Hereinafter, embodiments of the present invention will be described in detail.

  FIG. 1 is an exploded perspective view of a switch fixture showing a first embodiment of the present invention, FIG. 2 is a view showing a fixture constituting the switch fixture, FIG. 2 (a) is a front view, and FIG. 2B is a plan view, FIG. 2C is a bottom view, and FIG. 2D is a cross-sectional view taken along line AA in FIG. FIGS. 3A and 3B are diagrams showing a fastening tool constituting the switch mounting tool. FIG. 3A is a front view, FIG. 3B is a plan view, FIG. 3C is a bottom view, and FIG. ) Is a cross-sectional view taken along line B-B in FIG. FIG. 4 is a perspective view of a mounting state of a fixture and a fastener of a switch fixture according to the first embodiment of the present invention, and FIG. 5 is attached to a panel by the switch fixture according to the first embodiment of the present invention. FIG. 6 is a sectional view of the switch, and FIG. 6 is an explanatory diagram when the switch mounting tool is tightened. FIG. 6 (a) shows the state before the tightening operation, and FIG. 6 (b) shows the state during the tightening operation. FIG. 6C shows a state after the tightening operation (when the attachment is completed).

  1 to 6, a fastening protrusion 1 a provided with a fitting protrusion 1 b to be fitted to a thread 3 a of a switch 3 attached to the panel 4 is provided on the inner peripheral surface of the fixture 1, and rotation at the time of fastening. An anti-rotation protrusion 1c is formed to prevent this. Further, on the outer peripheral surface of the fixture 1, a mounting guide groove 1 d formed in the vertical direction for mounting the fixture 1 and the fastening tool 2, and a circumferential direction for guiding the rotation of the fastening tool 2 A rotation guide groove 1e formed on the rotation guide groove 1e is provided, and an end portion of the rotation guide groove 1e is formed with a stopper 1f for locking the fastener 2 at the time of fastening.

  The fastening tool 2 is loosely fitted with the fixing tool 1 and is guided by a guide protrusion 2a for locking the fastening tool 2 during fastening, and a tapered surface protruding in the circumferential direction for fastening the fastening protrusion 1a. A fastening groove 2b in which 2c is formed is formed.

  With this configuration, the guide protrusion 2a of the fastening tool 2 slides in the mounting guide groove 1d of the fixture 1 and is loosely fitted in the rotation guide groove 1e, and the switch mounting tool of the present invention is assembled.

  In the switch fixture of the present invention configured as described above, the switch 3 is inserted into the hole 4c provided in the panel 4 from the panel front surface 4a, and the switch fixture is rotated from the panel back surface 4b to the key groove 3b of the switch 3. The stopper protrusion 1c is fitted so that it engages, and is pressed against the panel back surface 4b to rotate, so that the fitting protrusion 1b of the fixture 1 is fitted to the thread 3a of the switch 3, and the guide protrusion 2a gets over the stopper 1f. By joining, the fastening tool 2 is locked and attached to the fixing tool 1. At this time, as shown in FIG. 6, the fixture 1 has a structure that does not rotate due to the engagement of the rotation stop projection 1c and the key groove 3b, and only the fastening tool 2 rotates, so that FIG. As shown in FIG. 6 (b), the tightening protrusion 1a is gradually pressed in the direction of the switch 3 along the tapered surface 2c of the tightening groove 2b, as shown in FIG. ), The fastening protrusion 1a is fastened to the screw thread 3a.

  On the other hand, when the tightening tool 2 is rotated in the reverse direction, the tightening protrusion 1a is released from the tapered surface 2c of the tightening groove 2b, the pressing force of the fitting protrusion 1b against the switch 3 is loosened, and the panel attachment 4 is pulled out. The switch 3 can be removed.

  Thus, the switch mounting tool shown in the present embodiment is composed of one unit of the fixing tool 1 and the fastening tool 2, and the switch 3 can be mounted on the panel 4 by rotating after being pushed. On the other hand, the switch 3 can be removed from the panel 4 by reversely rotating the fastener 2.

  Further, the switch 3 can be attached to the panel 4 with an appropriate pressing force by the fastening groove 2b having the fastening protrusion 1a of the fixing tool 1 and the tapered surface 2c of the fastening tool 2, and the end of the rotation guide groove 1e. By providing the stopper 1f on the surface, the pressing force can be maintained.

  FIG. 7 is a perspective view of a switch mounting tool in which finger hooking protrusions are provided on the lower surface of the fastener according to the second embodiment of the present invention.

  As described above, by providing the finger hooking protrusion 2d on the lower surface of the fastener 2, the switch 3 can be attached or operated by operating the finger hooking protrusion 2d even in a narrow place where the finger does not enter the side surface of the switch attachment. Removal can be performed easily.

  FIG. 8 is a perspective view of a switch mounting tool provided with a loosening prevention protrusion on the upper surface of a fastener showing a third embodiment of the present invention.

  Thus, by providing the loosening prevention protrusion 2e on the upper surface of the fastener 2, when the looseness prevention protrusion 2e is pressed against the panel back surface 4b when the switch 3 is mounted, the tip of the looseness prevention protrusion 2e is crushed. The repulsive force applies a pressing force in the direction opposite to the panel surface. Therefore, the fitting protrusion 1b formed on the tightening protrusion 1a can be more firmly fitted to the screw thread 3a of the switch 3, and the switch fitting can be prevented from loosening.

  In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.

  The switch attachment of the present invention can be used as a switch attachment to a panel that can be attached and removed without using a special tool by rotating after being pushed in.
