Reference numeral 27 is a shallow groove provided on the back surface between the step portion 22 and the bases of the locking pieces 25 a, 25 b, and 28 a, 28 b are groove grooves provided on the back surface on both sides of the groove 27. It is formed deeper than the groove 27. 29 is a jig insertion hole provided at the rear end. The jig insertion hole 29 may be a through hole or a bottomed hole. Also, a square hole and a round hole may be combined so that both a minus driver and a plus driver can be inserted. Reference numeral 30 denotes an inverted concave mounting member for mounting an electric device. In this embodiment, a rail having mounting pieces 31a and 31b on both sides is shown.

Next, the attaching / detaching action of the locking member 20 will be described. First, as shown in FIG. 4, the locking member 20 is opposed to the mounting portion 5 of the electric device body 1, and the sliding portions 21a and 21b thereof are inserted into the guide grooves 8a and 8b of the mounting portion 5 and pushed in. . At this time, since the concave grooves 28a and 28b pass on the stoppers 7a and 7b and the concave groove 27 passes on the protrusion 6 having the inclined surface, there is no problem in pushing. Further, as shown in FIG. 5, the locking pieces 25a, 25b of the locking member 20 are regulated by the stoppers 7a, 7b and elastically deform toward each other inward. When the locking member 20 is further pushed in, the recessed groove 27 is shallow, and therefore, when reaching the top of the protrusion 6, the corresponding portion elastically deforms and gets over the protrusion.

When the locking member 20 is further pushed in, the step portions of the sliding portions 21a and 21b come into contact with the step portions of the mounting portion 5 and stop. At this time, the locking pieces 25a, 25b return to their original states along the slopes of the stoppers 7a, 7b due to their elasticity as shown in FIG. 6, and the locking portions 26a, 26b move to the front side of the stoppers 7a, 7b. Positioned and held, the step portion 22 projects from the side wall 3 a of the recess 3 toward the recess 3.

Since they move, they elastically deform toward each other inward, and the locking member 20 moves in the arrow direction along the guide grooves 8a and 8b. When the pressing is stopped, the locking pieces 25a, 25b spread outward along the slopes of the stoppers 7a, 7b due to their elasticity, and the locking member 20 returns to its original position. It should be noted that if the locking member 20 is pressed in the direction of the arrow, it may come off from the mounting portion 5, but if it moves to some extent, the bottom of the groove 27 hits the protruding portion 6 and stops, so it does not move any further. .

Next, the operation of the present invention configured as described above will be described. First, as shown in FIG. 6, the locking member 20 is mounted on the mounting portion 5 of the electric device body 1. At this time, the step portion 22 of the locking member 20 projects into the recess 3. In this state, as shown in FIG. 8, the locking portions 4a and 4b provided on the bottom portion 2 of the electric device body 1 are fitted into one mounting piece 31a of the rail 30. At this time, the other mounting piece 31b of the rail 30 is located on the inclined surface 23 of the locking member 20. When the electric device body 1 is pushed down in this state (it is pushed up in the figure), the locking member 20 is guided by the guide grooves 8a and 8b, and the locking pieces 25a and 25b are elastically deformed inward, and the locking member 25a and 25b are elastically deformed. As shown in FIG. At this time, the protrusion 6 prevents the locking member 20 from falling off the mounting portion 5.

When the recess 3 of the electric device body 1 comes into contact with the mounting piece 31b of the rail 30, the locking member 20 automatically returns to its original position by the elasticity of the locking pieces 25a and 25b, as shown in FIG. As described above, the attachment piece 31b of the rail 30 is held between the recess 3 and the step portion 22 of the locking member 20, and the electric device body 1 is attached to the rail 30. In this state, since the locking portions 26a, 26b of the locking pieces 25a, 25b are elastically pressure-bonded to the stoppers 7a, 7b, there is no possibility that the locking member 20 will come off from the electric device body 1, and the electric device will not be released. The main body 1 is securely attached to the rail 30.

When the main body 1 of the electric device is removed from the rail 30, a driver or the like is inserted into the jig insertion hole 29 of the locking member 20 so that the locking member 20 resists the elasticity of the locking pieces 25a and 25b. Slide it to the right in the figure. As a result, the tip of the locking member 20 is disengaged from the mounting piece 31b of the rail 30, so that the electric device body 1 can be removed from the rail 30 by rotating it. When the electric device body 1 is disengaged from the mounting piece 31b of the rail 30, the locking member 20 slides leftward in the figure due to the elasticity of the locking pieces 25a and 25b, and returns to the original position.

To remove the locking member 20 from the electric device body 1, insert a screwdriver or the like into the jig insertion hole 29 of the locking member 20 and push up the locking member 20 to slide it to the right in the figure. It Thereby, the locking member 20 can be removed from the mounting portion 5 of the electric device body 1.

Embodiment 2 FIG. 11 is a sectional view showing a second embodiment of the present invention. In this embodiment, a protrusion 9 is formed on the outer wall above the central portion of the mounting portion 5 of the electronic equipment main body 1. It has been projected.

In the present embodiment configured as described above, when the locking member 20 is slid or removed from the electric device main body 1, a driver or the like inserted into the jig insertion hole 29 of the locking member 20 is projected. When the locking member 20 is brought into contact with the portion 9 and rotated about the fulcrum, the locking member 20 can be easily slid or removed from the mounting portion 5. In this case, if the inner wall of the jig insertion hole 29 of the locking member 20 is inclined so that the upper side becomes wider as shown by the broken line, the rotation range of the driver or the like can be expanded. Further, sliding or removal of the locking member 20 becomes easier.
