Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a component mounting device for temporarily mounting equipment components such as electrical outlets.

[Background technology]

Conventionally, as shown in FIG.
1 to the temporary mounting 82, both ends of the equipment component 81 are fixed with set screws 83.

A plurality of equipment parts 81 other than those shown are installed separately. A cover 84 has an equipment component exposure hole 85. The cover 84 is attached with cover attachment screws 86.

However, since both ends of the equipment component 81 are screwed, there are problems in that workability is poor when attaching and detaching the equipment component 81, and positional deviation of the equipment component 81 occurs.

In particular, when many equipment parts 81 are installed side by side and covered with a cover 84 as in this example, the ease of attaching/detaching each equipment part 81 and the ease of positioning will reduce the overall assembly time. It has a big impact. Further, when the equipment component 81 is an electrical component such as an outlet, it is necessary to once remove the equipment component 81 from the mounting temporary 82 and reinstall it for connection. Therefore, the ease of installation of each equipment component 81 is important.

In order to reduce the positional deviation, the mounting hole 87 of the equipment component 81 should be made as small as possible to eliminate the gap between it and the fixing screw 83. Insertion becomes difficult, and workability becomes worse.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a component mounting device that can easily attach and detach equipment components to a mounting plate and improve positioning accuracy.

[Disclosure of the invention]

In the component mounting device of the present invention, the mounting plate is provided with a permanent locking pawl and a positioning cover plate locking pawl that removably engage with the permanent locking hole and the temporary locking hole provided at both ends of the equipment component. The mounting plate is provided with a mounting hole located near the positioning cover plate locking pawl and for fixing the equipment component with a fixing screw.

According to the configuration of this invention, one end of the equipment component is locked to the mounting plate with the main locking claw, and the other end is attached with the positioning cover plate locking claw and fixed with the fixing screw, so that during transportation. When permanent fixing is not required, such as during temporary assembly or temporary assembly, by attaching only the main locking claw and the positioning cover plate locking claw, only the locking and removing operations can be performed without having to attach or remove the fixing screws. You can easily attach and detach equipment parts. In addition, in the case of final fixing, since the positioning is done by the positioning cover plate locking pawl, it is easy to tighten the fixing screw and the positioning accuracy is improved. Furthermore, since only one fixing screw is required, the workability of attaching and detaching is improved.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 7. This component mounting device includes a pair of main locking claws 4 and positioning cover plate locking claws 5 that are removably engaged with a permanent locking hole 2 and a temporary locking hole 3 provided at both ends of an equipment component 1, respectively. The mounting plates 6 and 7 are provided with mounting holes 9 located near the positioning thin plate locking claws 5 and into which the equipment component 1 is fixed with fixing screws 8. Upper mounting plate 6
Positioning claws 10 are provided on both sides of the main locking claw 4, and a positioning hole 11 into which the claws are inserted is provided in the equipment part l. Two positioning cover plate locking claws 5 and two temporary locking holes 3 are provided, and a mounting hole 9 is provided between them. Corresponding to the mounting hole 9, the equipment component 1 is provided with a screw insertion hole 12.

As shown in FIG. 2, the mounting plates 6 and 7 protrude opposite the main body 13, and a plurality of equipment parts 1 are mounted in a line. 14 is a shielding plate. Each equipment part
is the base play) 1a and the parts body 1b such as an outlet
Each of them has a similar structure and is attached to the mounting plate 6.7.

A cover 15 covers the mounting plate 6.7 and the equipment component 1, and is fixed to the main body 13 with cover fixing screws 16. The cover 15 has an equipment component exposure hole 17.

FIG. 3 shows details of the mounting plate 6.7. The locking claw 4, the positioning claw IO1, and the positioning cover plate locking claw 5 each consist of a cut-and-raised piece. The main locking pawl 4 faces diagonally upward, and the positioning pawl l
The O and positioning cover plate locking claws 5 face laterally.The O positioning cover plate locking claws 5 have a temporary locking notch 5a on the lower surface. The mounting hole 9 is a cylindrical protrusion with a tap cut on the inner surface. The upper and lower mounting plates 6 and 7 are in the fourth position in their natural state.
As shown in the figure, the tip is widened, and the equipment parts l
When they are fixed, they are elastically bent and become parallel as shown in Figure 3. In this parallel state, the dimension A1 between the main locking claw 4 and the positioning cover plate locking claw 5, and the dimension B between the positioning claw 10 and the mounting hole 9 are as shown in FIG.
The dimensions A' and B' are made to match each other. The dimension C' between the positioning holes 11 of the equipment part 1 is made to match the dimension C between the positioning claws 10, as shown in FIG. 3(C). The positioning claw IO is made such that the outer oblique angle α is 00 or more. As shown in FIG. 3(A), the dimension t1 of the flat part of the main locking claw 4, the dimension t2 of each part of the positioning cover plate locking claw 5. t3 is 0 locking claws 4 that is equal to or greater than the thickness t of the mounting plates 6 and 7.
The vertical dimensions of the positioning cover plate locking pawl 5 are made to match the dimensions D' of the positioning hole 11 and the temporary locking hole 3 shown in FIG.

Next, how to use this component mounting device will be explained. During transportation or temporary assembly, as shown in FIG. It is locked in the temporary locking notch 5a. In this state, the equipment part l is held by the restoring force due to the elasticity of the upper and lower mounting plates 6.7. When fixing the equipment part l, push the lower part of the equipment part l as shown in Fig. 5 (B). It is made to escape from the temporary locking notch 5a and brought into contact with the mounting plate 7. In this state, it is fixed with the fixing screw 8.

Then, as shown in FIG. 6, the cover 15 is attached to complete the assembly. At this time, the forward protrusion amount d of the equipment component 1 from the cover 15 is 0 or a positive value.

Installation is carried out in this way, with one end of the equipment component 1 being locked by the main locking claw 4, and the other end being locked by the positioning thin plate locking claw 5.
Since the equipment part 1 can be temporarily fixed by being locked with the , the equipment part 1 can be easily attached and detached by only a locking/disengaging operation. Therefore, the equipment part 1 can be shipped with it temporarily fixed to the mounting plate 6.7, and problems caused by loss or misplacement at the site can be prevented. Furthermore, there is no need to remove screws, making it easy to perform wiring connections on site. During temporary fixing, the equipment component 1 is reliably held in a locked state by the elasticity of the mounting plates 6 and 7, so it is difficult to fall off even if it is carried upside down, making transportation and construction easy.

In this fixed state, since it is fixed with the fixing screw 8, it will not fall off due to impact or the like. Since only one fixing screw 8 is required, screw tightening work is easy. Moreover, the removal work after being fixed once is also easy. Moreover, since the positioning is done by simply inserting the thin positioning plate locking pawl 5 and the positioning pawl 11, it is easy to tighten the fixing screw 8.
Positioning accuracy is also improved. Since the positioning accuracy is improved in this way, there is no need to make the component exposure hole 17 of the cover 15 larger than necessary, and unsightly appearance of gaps and the like can be prevented.

Furthermore, since only the positioning front plate locking pawl 5 and the like are provided, the structure is simple.

In the above embodiment, the thin positioning plate locking pawl 5 and the main locking pawl 4 are formed of cut and raised pieces, but they may be formed of a separate member from the mounting plate 6.7.

〔Effect of the invention〕

In the component mounting device of the present invention, one end of the equipment component is locked to the mounting plate with the main locking claw, and the other end is attached with the positioning thin plate locking claw and fixed with the fixing screw.
When permanent fixation is not required, such as during transportation or temporary assembly, by attaching with only the main locking claw and the positioning thin plate locking claw, it is possible to perform the locking/disconnecting operation without attaching or removing the fixing screw. Equipment parts can be easily attached and detached using only a chisel. Also,
In the case of final fixation, since the positioning is done by the positioning thin plate locking pawl, the fixing screw can be easily tightened and the positioning accuracy is improved. Furthermore, since only one fixing screw is required, there is an effect that the workability of attaching and detaching is improved.
