Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a case insertion device, which has a simple structure that allows for easy insertion without using set screws when attaching a case to the main body. This paper proposes a case insertion device.

(Prior Art) As shown in perspective in FIG.
In this case, the tips 3a of another case 3 are superimposed and the tips 2a and 3a are fixed to each other using a set screw 4, or the tips of the cases 5 and 6 are fixed as shown in FIG. 5a, 6a, front and back back plates 7, 8
Generally, the tips 5a and 6a are fixed to each other together with the contact plates 7 and 8 using scissors and a set screw 9.

(Problems to be solved by the invention) In the conventional case mounting device described above, each case is fixed to each other with set screws, so it is troublesome to align the screw holes of both cases, and deformation occurs. In the case of a thin-walled case that is easy to attach, it takes a long time to align the screw holes.

(Means for solving the problem) This invention was devised so that two cases could be fixed to each other without using set screws, reducing the number of assembly steps.
a notch 12 provided in the end edge 11a of the main body 6; and a contact portion 7 formed in the main body 6 to abut a part of the inner surface of the case 11 when the case 11 is inserted.
A pin 8 protruding from the abutting part 7 so that the notch 12 can be fitted outwardly, and a flange 9 formed on the pin 8, and the distance from the back surface 9a of the flange 9 to the abutting part 7. l is the plate thickness t near the notch 12 of the case 11
Pin 8 is slightly shorter than the pin 8.
A recess 10 provided in the main body 6 around the base of the
This is a case insertion device having the following.

(Function) Since the distance 1 from the back surface 9a of the flange 9 of the pin 8 to the contact portion 7 of the main body 6 is slightly shorter than the plate thickness t near the notch 12 of the case 11, the case 1
When the notch 12 of 1 is fitted onto the pin 8, the notch 1
The end edge 11a near the flange 9 is elastically deformed toward the recess 10 by the back surface 9a of the flange 9, and the case is sandwiched between the abutting portion 7 and the flange 9. 11 is inserted into the main body 6.

Since the notch 12 is elastically deformed toward the recess 10 in this way, the case 11 is inserted into the main body 6, and the case 11 can be attached to the main body 6 without using a set screw or the like. It became.

(Example) Next, an example of this invention will be described based on the drawings.

The front view is shown in FIG. 6, and a part of the vertical side surface is shown in FIG. A recess 10 is provided in the main body 6 around the base of the main body 8 .

The case 11, whose front side is shown in FIG. 4 and the side view shown in FIG.

Since the distance l from the back surface 9a of the flange 9 to the abutment part 7 is formed to be slightly shorter than the plate thickness t in the vicinity of the notch 12, when the notch 12 is fitted onto the pin 8, the notch The edge portion 11a near the portion 12 is the flange portion 9.
The end edge 11a is pushed and bent toward the recess 10 by the back surface 9a of the back side 9a, and the end edge 11a is elastically deformed as shown in FIGS. 1 and 3.
The case 11 is inserted into the main body 6 with the front and back sides sandwiched together.

By fitting the notch 12 of the case 11 to the pin 8 in this way, the case 11 can be elastically compressed and supported by the collar 9 and the abutting part 7.

(Effect of the invention) As described above, the case insertion device according to this invention has the distance l from the back surface 9a of the flange 9 of the pin 8 to the abutment part 7 of the main body 6 close to the notch 12 of the case 11. Since it is formed to be slightly shorter than the plate thickness t of the case 11, when the notch 12 of the case 11 is fitted onto the pin 8, the edge 11a near the notch 12 will fit into the flange 9.
is elastically deformed toward the recess 10 by the back surface 9a of the
As a result, the case 11 is elastically inserted into the main body 6.

To provide a case insertion device that can easily attach the case 11 to the main body 6 without requiring set screws, eliminates the need for screw hole alignment, etc. for attaching set screws, and is low in cost. It became.
