[Detailed Description of the Invention] [Technical Field] This invention relates to a mounting base for electrical components such as photoelectric switches.

[Background Art] A mounting stand is used when mounting an electrical component such as a photoelectric switch on a structure. This mounting base, for example, a mounting base 50 for a photoelectric switch, as shown in FIG. A locking protrusion (locking part) 54 was provided on the inner surface to lock the photoelectric switch by engaging with a locking recess (locked part) provided on the side surface of the photoelectric switch. . This mounting base 50 has a fifth
A photoelectric switch 55 is attached as shown in the figure.

In the figure, 58 is a connector portion for a wiring cable, and 59 is a tip portion that becomes a light receiving surface.

To attach the photoelectric switch 55, as shown in FIGS. 6a and 6b, push the photoelectric switch 55 between the elastic pieces from the direction of the arrow in the figure, and then press the locking recesses 56 provided on the side of the photoelectric switch. It is made to engage with the locking protrusions 54. Locking protrusion 54
The pitches between the locking recesses 56 are aligned with the pitches between the locking recesses 56 to prevent the photoelectric switch from shaking after installation. However, this made it difficult to install the photoelectric switch. Moreover, in this mounting base 50,
When removing the photoelectric switch, as shown in Fig. 7, use a flathead screwdriver 57 or the like to bend the elastic pieces 52, 52 at one end in the direction of the arrow in the figure, so that the locking protrusion and the locking recess are connected. It was necessary to pry the engagement open, which was troublesome.

[Purpose of invention]

In view of the above circumstances, the object of this invention is to provide a mounting base for electrical components that allows electrical components to be easily attached and removed.

Furthermore, this invention requires that the electrical component be left open due to circumstances such as the photoelectric switch where one side is a light receiving surface, and the other side is provided with a connector section. Another object of the present invention is to provide a mounting base for electrical components that can be easily mounted and removed by taking into account the wiring cables of the connector section.

[Disclosure of invention]

In order to achieve the above object, this invention includes elastic pieces that stand up at both ends of the base so as to sandwich the main body of the electrical component, and on the opposing inner surfaces of each elastic piece, elastic pieces are provided on the sides of the electrical component. In an electrical component mounting stand that is provided with a locking portion that locks the electrical component by engaging with a locked portion, one side of the electrical component must be open for functionality. In addition, the other side is provided with a connector section for wiring, and among the elastic pieces of the mounting base, the elastic piece disposed on the side of the connector section of the electrical component has an extension extending further from the locking section. The gist of the present invention is a mounting stand for an electrical component, which is characterized in that it has a bifurcated protrusion and stands up from both sides with a connector portion of the electrical component in between.

This will be explained in detail below with reference to the drawings showing one embodiment thereof.

As shown in Figure 1, the photoelectric switch mounting base 1
The base part 2 is provided with screw holes 3, 3, so that it can be fixed to a structure by tightening the screws. Both ends of the base portion 2 are provided with elastic pieces 4, 4, 5, and 5, two each standing upright. When the photoelectric switch 55 shown in FIG. 5 is installed, a connector part 58 for connecting a cable for wiring the photoelectric switch is provided between the elastic pieces 4 at one end, and a connector part 58 is provided between the elastic pieces 5 at the other end. The distal end portion 59 serving as the light receiving surface of the photoelectric switch has a shape corresponding to that between the elastic pieces so that the main body portion 60 of the photoelectric switch can be fitted between the elastic pieces at one end and the other end. On the opposing inner surfaces of each of these elastic pieces, there is a locking protrusion (locking part) that locks the photoelectric switch by engaging with a locking recess (locked part) provided on the side surface of the photoelectric switch. 6, 6, 7, 7 are provided. The pitch between each locking protrusion 6, 6, 7, 7 is
These are aligned with the pitch between the engaging recesses to prevent the photoelectric switch from shaking after the photoelectric switch is installed. The elastic pieces 4, 4 at one end are bifurcated with extending pieces 8, 8 further extending from the locking protrusions 6, 6.

To attach the photoelectric switch to the photoelectric switch mounting base 1, as shown in FIGS. Push the elastic pieces 4, 4, 5, and 5 between the elastic pieces 4, 4, 5, and 5 from the direction, and insert the locking recesses 56 provided on the sides of the photoelectric switch into the locking protrusions 6,
6, 7, and 7. At this time, since the mounting base 1 according to this invention is provided with extending pieces 8, 8, these extending pieces 8, 8 serve as guides for attaching the photoelectric switch, making it easy to attach the photoelectric switch. . At this time, it is necessary to consider the orientation of the photoelectric switch 55 and the mounting base 1. That is, since the tip 59 of the photoelectric switch 55 becomes a light receiving surface, there must be no obstruction in front of the tip 59 and it must be open. It is also necessary to prevent hands from touching the light-receiving surface. Therefore, the elastic pieces 4, 4 having the extension pieces 8, 8 that are operated during removal are arranged on the side of the connector portion 58 opposite to the tip portion 59. moreover,
The connector portion 58 is sandwiched between the extending pieces 8, 8 of the bifurcated elastic pieces 4, 4 from both sides. To remove the photoelectric switch, as shown in FIG.
6 and 56, and lift the photoelectric switch 55 from the connector side. At this time, in the mounting base according to this invention, since the extending pieces 8, 8 are provided on the upright elastic pieces 4, 4 so as to extend further than the locking protrusions 6, 6, the locking protrusions 6, 6 and the locking recesses 56, 56 can be opened with a light force. Therefore, according to this invention, the photoelectric switch can be removed by bending the extension pieces 8, 8 with your fingers, without having to pry it open using a flathead screwdriver or the like as in the past. become.

The mounting base for electrical components according to this invention is not limited to the above embodiment. In addition, as an electrical component, one side is equipped with a connector for wiring, and the other side, like the light receiving surface of a photoelectric switch, is designed to function as an electrical component so that the front side is not obstructed by obstacles. It is applied to structures that have a surface that must not be touched or touched, that is, a surface that must be left open for functional reasons.Specifically, the above-mentioned photoelectric switch can be mentioned. .

[Effect of idea]

As seen above, in the electrical component mounting base according to this invention, the upright elastic piece is provided with an extending piece that extends further than the locking part. Therefore,
When attaching electrical components, the extending piece serves as a guide for attaching the electrical components, making attachment easier. Moreover, when removing electrical parts,
Electrical parts can be removed by bending the extension piece with one's fingers, and can be easily removed without using a flat head screwdriver or the like as in the past.

In particular, the mounting base of this invention can be used as an electrical component.
For its function, it is necessary to leave one side open, and the other side is suitable for attaching a structure having a connector section for wiring.

In other words, if the elastic piece with the extending piece is placed on the side of the electrical component that needs to be left open, the light receiving surface of the photoelectric switch may be blocked, or when the extending piece is operated by hand. There is a problem with touching the light-receiving surface and contaminating it. However, in this invention, since the elastic piece with the extending piece is provided only on the connector portion side, the above-mentioned problem is solved.

However, since the wiring cable is connected to the connector part on the connector part side, it is necessary to provide the extending piece and the elastic piece at a position where they do not interfere with the wiring cable. Therefore, in this invention, the elastic pieces are provided at the ends of the sides instead of at the center.

However, if the elastic piece is provided only at one end of the side surface, it may become impossible to operate the extending piece depending on the mounting conditions of the electrical components.
That is, if the electrical component is installed near a wall or if there is an obstacle on one side, the extending piece may be hidden between the electrical component and the wall or obstacle.

As mentioned above, the mounting base of this invention has elastic pieces with extension pieces arranged in accordance with the positional relationship between the connector side of the electrical component and the side that needs to be opened. There is no way to flip the mounting base back and forth so that the piece is on the front side.

Therefore, in this invention, elastic pieces with extending pieces are arranged on the side surface on the side of the connector part, and are provided on both sides with the connector part in between. That is, the elastic piece with the extending piece is made into a bifurcated shape. As a result, if either of the extending pieces is exposed, it becomes possible to manipulate the extending pieces. Even if you only operate one extension piece, the left and right elastic pieces are connected together at their bases, so both elastic pieces will deform and move, releasing the engagement with the electrical component. .

As a result of the above, with this invention, even if the electrical parts have a special structure as mentioned above, which has many restrictions on installation,
It can be installed reliably and with good workability without any problems.
