The mounting plate and the mounting structure of the device having a restricting portion near the end of the mounting plate for restricting the device from moving to the end when the lever of the device protrudes, the lever having a bottom surface. An object of the present invention is to provide a mounting structure of a device to a mounting plate of a device which can be easily mounted without a risk of a lever being damaged when the device is to be mounted from an end side of the mounting plate while protruding from the mounting plate. I have. [0005] Accordingly, the present invention is directed to:
The mounting plate is provided with a connecting part which regulates the movement in the direction perpendicular to the mounting surface and is opened in one direction substantially parallel to the mounting surface and at one end side of the mounting plate. A mating part to be inserted into and mated with the mating part is provided, and a lever is provided for selectively holding the protruding or not protruding from the mounting surface of the device, and the lever of the device protrudes from the mounting plate. In the mounting plate and the mounting structure of the device having a restricting portion near the end of the mounting plate for restricting the movement of the device toward the end when the device is mounted, the lever is attached to the device with respect to the insertion direction of the device. The present invention provides a mounting plate and a device mounting structure characterized by having an inclined surface. Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 4 show a structure for mounting the above-described circuit breaker to a mounting plate.
The relationship between the figure and the claims of the present invention will be described. Reference numeral 2 denotes a mounting plate which has a joint portion 4 which restricts movement in a direction perpendicular to the mounting surface of the mounting plate and is opened in the direction of the end side 801 of the mounting plate substantially parallel to the mounting surface. Reference numeral 1 denotes a device, which has a mating portion 6 which is inserted into the mating portion 4 from the end 801 side and fits into the mating portion 4 on the mounting surface side, and which is either protruding from the mounting surface of the device 1 or not. And a lever 7 for selecting and holding. The mounting plate 2 has a restricting portion 8 near the end of the mounting plate for restricting the device 1 from moving toward the end 801 when the lever 7 of the device 1 projects. The attachment of the device 1 to the attachment plate 2 is as described above, and a description thereof will be omitted. Reference numeral 10 denotes a projection for positioning the mounting plate of the device 1 with respect to the mounting plate, reference numeral 3 denotes a connection portion opened to the end portion 801 similarly to reference numeral 4, and reference numeral 5 denotes a device-side cover connected to the connection portion 3 of the device 1. Although it is a connection part, the position of the connection part 4 and the dimensional relationship between the connection part 6 and the part to be connected need not be appropriately selected. FIG. 5 and FIG. 6 are cross-sectional views of the inside of the housing of the device 1 around the lever 7, FIG. 5 is a view of the embodiment of the present invention, and FIG. In the figure, reference numeral 702 denotes a knob, which is pinched by a finger to project the lever 7 from the bottom of the device.
Do not work. 703 is a protrusion. Reference numeral 17 denotes a projection on the housing side of the device, which is connected to the concave portion 18 or 19 of the lever 7. 5 and 6 both show a state in which the protruding portion 703 protrudes from the bottom surface and is held.
Reference numeral 7 indicates the position of the concave portion 18 in relation to the concave portion 18. The lever 7 is made of resin and has some elasticity. When the knob 702 is pulled up from the state shown in the drawing, the projection 17 moves over the recesses 18 and 19 and moves to the 19 side, and the levers 7 are connected to each other. 7
03 is a state where it does not protrude from the bottom surface of the device 1. In FIG. 5, reference numeral 20 denotes an inclined portion provided in the insertion direction of the device of the lever 7 of the present invention. When the device 1 is to be mounted on the mounting plate 2 as shown in FIG. 1 with the lever 7 protruding from the bottom surface of the device 1 as shown in the figure, in the conventional example as shown in FIG. Although there is a possibility of being broken by being caught on the end 801 of the plate 2, in the present invention of FIG.
When the end portion 801 of the mounting plate 2 comes into contact with the protruding portion, the lever 7 retracts to a state in which the lever 7 does not automatically protrude due to the component force of the inclined surface due to the action of the inclined portion 20, and there is no risk of breakage. . If the lever 7 is manually pushed down after the mating portion 4 is completely connected to the mating portion 6, the protrusion 703 protrudes into the regulating portion 8 and the attachment of the device 1 to the mounting plate 2 is completed. . Therefore, the device can be inserted and fixed to the mounting plate without worrying about the projecting state of the lever 7. In the above description, the inclination angle and the shape of the inclined portion 20 can be arbitrarily changed within the scope of the present invention. Although the circuit breaker is used in the embodiment, the present invention can be applied to equipment other than the circuit breaker in relation to the mounting plate. As described above, according to the present invention, the movement of the mounting plate in the direction perpendicular to the mounting surface is restricted, and the mounting plate is opened substantially in parallel with the mounting surface in one direction on the end side of the mounting plate. The device is provided with a mating portion that is inserted from the end side into the mating portion and fits into the mating portion, and it is possible to select whether or not to protrude from the mounting surface of the device. The mounting plate is provided with a restricting portion near the end of the mounting plate, the mounting plate having a restricting portion for restricting movement of the device toward the end when the lever of the device protrudes. In the mounting structure, when the device is to be mounted from the end of the mounting plate with the lever protruding from the bottom, the lever can be easily mounted without any risk of damage to the mounting plate. It is intended to provide.
