Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for mounting a unitized electrical assembly (such as a plug-in unit) to a device body using a connector.

FIG. 1 is a diagram showing an example of a conventional mounting device of this type.

In FIG. 1, 10 is a unit assembly formed in the shape of a rectangular parallelepiped, and is formed of a panel 20 made of an insulating material and a case 30 made of a metal material, both of which are attached with screws (not shown). ing.

Reference numerals 40 and 50 indicate mounting members fixed to the main body of the device at predetermined intervals.

The mounting member 40 has a screw hole 41 formed therein for mounting the mounting member 40 to the case 30 using a screw 31.

Similarly, screw holes are formed in the mounting member 50 as well.

33 is a contact portion of a printed board provided at the bottom of the case 30, and 60 is a connector coupled to this contact portion 33, which is attached to the main body of the device.

In a device having such a configuration, in order to attach the unit assembly 10 to the main body of the device, the case 30 portion of the unit assembly 71 is guided by the mounting members 40° and 50, and the printed circuit board contact portion 33 is inserted into the connector 60. do.

After the insertion is complete, attach the case 30 to the mounting member 40 with screws.
Attach to 50.

Such unit assembly mounting devices have been used in the past.

Here, since the panel 2o is integrally molded, it can be manufactured with less variation in dimensions.

On the other hand, the case 30 is made of a metal material (sheet metal), but the case 20 made of a metal material has variations in dimensions 11.12 of the finished case.

In the apparatus shown in FIG. 1, the contact portion 33 of the printed circuit board is connected to the connector 60 using the case 30 as a guide, but as mentioned above, the case 30 has large variations in dimensions, making it difficult to position the unit assembly.
The printed board contact portion 33 cannot be easily guided.

Furthermore, the mounting members 40 and 50 require a complicated shape.

The present invention was mainly made to improve these points, and it is possible to ensure the positioning of the unit assembly,
Moreover, the guide to the connector can be easily performed.

The figure is an explanatory diagram of the main parts of an embodiment of the mounting device according to the present invention.

In the figure, 10 is a unit assembly formed in the shape of a rectangular parallelepiped, and is composed of a panel 20 made of an insulating material and a case 30 made of a metal plate, both of which are attached together with screws (not shown). ing.

In the panel 20, 21 is one side of the panel 20.

Recesses 22 and 23 are formed on both sides of the lower portion of the side surface 21.

A T-shaped protrusion 24 is formed on the side surface 21 and protrudes from the recesses 22 and 23.

Similar recesses 22' and 23' and an accompanying T-shaped protrusion 24' are formed on the side surface 21' opposite to the side surface 21.

In the case 30, a spacer 32 made of an insulating material is attached to the lower center of the side surface 31 that is the same as the side surface 21 of the panel 20.

The thickness of the spacer 32 from the side surface 31 of the case 30 is equal to the thickness of the recesses 22 and 23 formed in the panel 20, and a screw hole 33 is formed in this spacer 132.

Reference numeral 40 denotes a printed board, and this printed board is disposed inside the case 30 in a direction perpendicular to the side surface 31 of the case 30.

The contact portion 41 of the contact plate of this printed circuit board protrudes from the case 30, and the pattern 42 includes nos.
Components of an electric circuit placed within the space 30 are connected.

Reference numerals 50 and 60 denote frames, each of which is fixed to a fixing member of the main body of the device.

- The upper part of the room 50 is provided with a notch 51 into which the protrusion 24 formed on the panel 20 of the assembly 10 is fitted.

Similarly, a notch 61 is formed in the frame 60, into which the protrusion 24' is fitted.

A through hole 52 is provided in the frame 50 at a position corresponding to the screw hole 33 formed in the spacer 32 attached to the side surface 31 of the case 30.

At the distance between frames 50 and 60, recesses 22 (23) and 22' (23) are formed in panel 20 across the width of case 30.
') is equal to the size l'.

Reference numeral 70 denotes a connector, which connects the printed board 40 when the case 30 is inserted into the frames 50 and 60.
The contact portion 41 is attached to a fixing member of the main body of the device at a position such that the contact portion 41 can be inserted into the connector 70.

In the mounting device having such a configuration, the protrusions 24 and 24' formed on the panel 20 of the assembly 10 are attached to the frame 5.
0 and 60 so that they fit into the notches 51 and 61,
Insert case 30 into frames 50 and 60.

During the insertion, the contact portions 41 of the printed board 40 are easily inserted into the connector 70.

After the assembly 10 has been inserted into the frames 50 and 60, the screw 80 is screwed into the screw hole 33 of the spacer 32 provided in the case 30 through the through hole 52 formed in the frame 50.

As described above, in the device of the present invention, when the assembly 10 is installed in the frames 50 and 60, the protrusions 24 and 24' formed on the panel 20 are fitted into the notches 51 and 61 of the frames 50 and 60. This restricts movement in the direction of arrow A in the figure.

Furthermore, the movement of the assembly 10 in the three directions is restricted by entering the four parts 22, 23 and 22' provided on the side surface of the panel 20, and the four parts 23 and 23 being inside the frames 50 and 60.

Further, the L lower mill of the assembly 10 is controlled by a screw 80, but this screw is the only member required for fixing the assembly 10 that requires electrical insulation.

As described above, the mounting device of the present invention (in this case, protrusions are formed on each of the inner surfaces facing χ4 of a panel made of an insulating material, and notches are formed in both frames to fit into these protrusions. As a result, the unit assembly can be accurately positioned using the protrusion and the notch, and the unit assembly can be positioned using the protrusion as a guide.
- The printed board contact portion provided in the assembly can be easily connected to the connector.

Moreover, in the device of the present invention, the case can be installed while being insulated from the main body of the device, so positioning,
Due to the ease of guiding, accuracy, and simple structure, the device of the present invention is extremely suitable as a device for attaching a unit assembly of an electrical device to the main body of the device.
