Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a coupling device capable of mechanically coupling, for example, two or more objects.

[Technical background of the invention and its problems]

Conventionally, the purpose of a coupling device for mechanically coupling two or more objects has been to mechanically couple them at the time of coupling, as shown in FIG. That is,
When connecting the separating body 2 to the fixed body 1, a lock lever 3, which is rotatably provided on the separating body 2 via a screw 5 and is made of a material with strong mechanical strength such as a steel plate, is attached to the fixed body. It fitted into the recess 4 of No. 1 to connect the two. Also, this fixed item 1 and separated item 2
When electrically coupling these, a separate power supply connector 6 was provided to couple them. Therefore,
There are two joints, a mechanical part and an electrical part, and depending on the work, there may be cases where they are connected mechanically but not electrically.
There were problems such as the device not working even when the power was turned on.

[Purpose of the invention]

This invention was made based on the above-mentioned circumstances, and it is possible to perform mechanical coupling and electrical coupling at the same time with one touch via a lock lever, and it is possible to reliably couple both, and the structure is extremely simple. The object of the present invention is to provide a highly reliable coupling device.

[Summary of the idea]

This idea is to provide a power feeding part to the lock lever of the separate body and a power receiving part to the engaging part of the fixed body, so that when the lock lever is engaged with the engaging part, the power feeding part is connected to the power receiving part at the same time. It is characterized by the following.

[Example of idea]

This invention will be explained with reference to an embodiment shown in the drawings.

FIG. 2 is a front view showing an embodiment of the coupling device of this invention, and FIG. 3 is a side view of the same. In each figure, the same members as in FIG. 1 are given the same reference numerals, and detailed explanations of their structures will be omitted. The configuration different from that shown in FIG. 1 is that a lock lever 3 is rotatably provided on a separate body 2 via a screw 5 and is made of plastic or insulating resin, and this lock lever 3 has a power supply section connected to a power supply wire 7. 8a, 8b, and 8c are formed, respectively. On the other hand, a support piece 9 is attached to the lower part of the engaging portion (recess in the drawing) 4 of the fixed member 1, and the support piece 9 is provided with power receiving portions 10a, 10b, and 10c. A power receiving wire 11 is connected to each of the power receiving sections 10a, 10b, and 10c.

In the coupling device configured in this way, when the lock lever 3 is rotated in the direction of the arrow A about the screw 5, a part of the lock lever 3 moves into the recess 4 of the fixing member 1.
Fits inside. As a result, the lock lever 3 and the recess 4 are mechanically coupled, and the power feeding parts 8a, 8b, 8c of the lock lever 3 and the power receiving parts 10a, 10b, 10c of the support piece 9 of the recess 4 are electrically connected, respectively. The connection will be made (the state indicated by the chain line in Fig. 2).

On the other hand, when separating the separating member 2 from the fixed member 1, if the lock lever 3 rotatably provided on the separating member 2 via the screw 5 is removed from the recess 4 of the fixed member 1, the mechanical At the same time, the electrical coupling between the power feeding parts 8a, 8b, 8c of the lock lever 3 and the power receiving parts 10a, 10b, 10c of the support piece 9 of the recess 4 is also released (as shown by the solid line in Fig. 2). condition). Then, the separating body 2 is separated from the fixed body 1.

It should be noted that the above embodiment is merely an example, and it goes without saying that each member can be replaced with another member having the same function. For example, in the embodiment described above, the power supply parts 8a, 8 of the lock lever 3
b, 8c and power receiving parts 10a, 10b, 10 of recess 4
Although shown is a configuration in which the two are in surface contact with each other, the present invention is not limited to this, and any configuration may be used as long as the two can be electrically coupled. and power supply parts 8a, 8
It goes without saying that the number of the power receiving units 10a, 10b, 10c and the power receiving units 10a, 10b, 10c can be set to an appropriate number depending on the device used. Furthermore, the same effect can be obtained even if the power feeding side and the power receiving side are installed in opposite positions.

[Effect of idea]

Since this invention is constructed as described above, when two objects are mechanically and electrically connected, they can be connected simultaneously by operating the lock lever, thereby preventing operational errors. In addition, there is no need to provide a separate connector,
It has excellent effects such as being able to reduce costs, have an extremely simple configuration, and have high reliability.
