Abstract

PURPOSE:To prevent engagement of a movable side pawl with a movable side mounting hole from becoming incomplete by forming a bent piece at the end of a stationary side. CONSTITUTION:In order to attach a wiring implement 5 to a holding frame 1, a stationary side pawl 17 is inserted into a stationary side mounting hole 8, and a movable side pawl 18 is then inserted into a movable side mounting hole 11. Since a bent piece 19 is formed at the pawl 17 at the time of mounting, the pawl 17 is passed through the hole 8 in a state that a connecting implement 5 is inclined, then returned to a horizontal state, and the pawl 18 is inserted into the hole 11. Since the piece 19 is provided, the pawl 17 is not stopped on the way of the hole 8, completely attached or completely detached, and not incompletely attached.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to electrical appliances such as electrical wiring devices such as switches, telephone modules, and antenna terminals.

2. Description of the Related Art Conventionally, as seen in, for example, Japanese Utility Model Publication No. 58-32420, there has been a system in which electrical wiring devices such as switches are attached to an elastic frame made of synthetic resin. In other words, the fixed side frame has a fixed side mounting hole that penetrates in the direction along the mounting surface, and the movable side frame has a movable side mounting hole that penetrates in the direction along the mounting surface and has an elastic stopper. An elastic frame body made of synthetic resin is formed, and a fixed side pawl body is inserted into the fixed side mounting hole along the mounting surface and a fixed side claw body is inserted into the movable side mounting hole and is attached to the stopper piece. An electric appliance having a fixed movable claw body is attached.

Problems to be Solved by the Invention In the conventional system using an elastic frame, claws provided on the instrument body are engaged with the fixed-side mounting hole and the movable-side mounting hole. The method is to completely insert the fixed side claw body into the fixed side mounting hole, then insert the movable side claw body into the movable side mounting hole, and then make the claw body contact the stopper piece to prevent it from falling off. It is fixed at

However, in the conventional device, the movable claw can be inserted into the movable mounting hole even if the fixed claw does not completely enter the fixed mounting hole. However, when the fixed side claw body is not completely inserted into the fixed side mounting hole, the movable side claw body is not fully fitted into the movable side mounting hole, and the instrument may shift laterally. Furthermore, when attaching a handle cover later, the handle cover may not be set in the correct position, causing problems such as poor movement.

Means for solving the problem A fixed side frame body is formed with a fixed side mounting hole that penetrates in the direction along the mounting surface, and a movable side mounting hole that penetrates in the direction along the mounting surface and has an elastic stopper. A holding frame consisting of a movable side frame and a fixed side claw inserted into the fixed side mounting hole and along the mounting surface, and a movable side claw inserted into the movable side mounting hole and fixed by the stop piece. In the electric appliance provided with a body, a bent piece is integrally bent and formed at the tip of the fixed side claw body.

Function: Since a bent piece is formed at the tip of the fixed side claw body, when the fixed side claw body is inserted into the fixed side mounting hole, it is either completely inserted or not inserted at all. Therefore, the engagement of the movable side claw body with the movable side mounting hole is either completely engaged or not engaged, and therefore, the engagement of the movable side claw body with the movable side mounting hole is difficult. There is no longer a situation where the parts are incompletely fitted, and the correct installation state can always be obtained.

Example An embodiment of the present invention will be described based on the drawings.

First, a holding frame l made of synthetic resin is provided. This holding frame 1 has a rectangular square frame shape, and its short side is used as a mounting fixed part 2, one of its long sides is a fixed side frame 3, and the other side is a movable side frame. body 4
It is. Three wiring devices 5, which are electrical appliances, are attached to such a holding frame l along its long sides, but in actual construction, the necessary number of wiring devices 5 are attached. is installed.

Therefore, the fixed side frame body 3 of the holding frame 1 has an L-shaped cross section with a horizontal surface 6 as a mounting surface and a vertical surface 7 perpendicular to the horizontal surface 6. A fixed side attachment hole 8 along the horizontal surface 6 is formed at the base of the surface 7 . Furthermore, the movable side frame 4 also has an L-shaped cross section with a horizontal surface 9 serving as a mounting surface and a vertical surface lO perpendicular to the second horizontal surface 9; A movable side attachment hole 11 is formed along the horizontal surface 9. And this movable side mounting hole 1
A stopper piece 12 is formed in the center of 1 and projects vertically.

□The connecting device 5 has a main body case 14 which is provided with a switch mechanism inside and has two plate mounting portions 13 movably protruding from the upper surface. This main body case 14 has two metal plate fittings 15.1.
These fixtures 15 and 16 have fixed side claws 17 and movable side claws 18 that engage with the fixed side mounting holes 8 and the movable side mounting holes 11, respectively. It is formed protrudingly. A bent piece 19 that is bent downward is formed at the tip of the fixed side claw body 17. The bending length of the bending piece 19 is set to such an extent that the fixed side claw body 17 can pass through the fixed side attachment hole 8 when the connecting device 5 is tilted.

In such a configuration, when attaching the wiring fixture 5 to the holding frame 1, the fixed side claw body 17 is inserted into the fixed side attachment hole 8, and then the movable side claw body 18 is inserted into the movable side attachment hole 11. insert. At the time of this installation, since the fixed side claw body 17 is formed with the bent piece 19, the connecting device 5
The fixed side pawl body 17 is passed through the fixed side attachment hole 8 in an inclined state, and then returned to the horizontal state, and the movable side pawl body 18 is inserted into the movable side attachment hole 11.

Therefore, the state in which the movable claw body 18 can be inserted into the movable attachment hole 11 is when the fixed claw body 17 is completely attached to the fixed attachment hole 8. That is,
Because of the bending piece 19, the fixed side claw body 17 does not stop halfway in the fixed side attachment hole 8, and is either completely attached or not attached. Of course, if the fixed side claw body 17 is not inserted into the fixed side attachment hole 8, it is impossible to attach it in the normal case.

Although it is possible to consciously insert the movable side claw body 18 into the movable side mounting hole 11, in this case, the connecting device 5 cannot be tilted, so the fixed side claw body 17 cannot be inserted into the fixed side mounting hole 11. Insertion into hole 8 is not possible.

Effects of the Invention As described above, the present invention has a fixed side frame body in which a fixed side mounting hole is formed which penetrates in a direction along the mounting surface, and a movable side frame body which penetrates in a direction along the mounting surface and has an elastic stopper. A holding frame consisting of a movable side frame body with a mounting hole formed therein is fixed by a fixed side pawl body along the mounting surface that is inserted into the fixed side mounting hole and a stop piece that is inserted into the movable side mounting hole. In an electric appliance provided with a movable claw body, a bending piece is integrally formed at the tip of the fixed claw body.
Since a bent piece is formed at the tip of the fixed side claw body, when the fixed side claw body is inserted into the fixed side mounting hole, it is either completely inserted or not inserted at all. Therefore, the engagement of the movable side claw body with the movable side mounting hole is either completely engaged or not engaged, and therefore, the fitting of the movable side claw body into the movable side mounting hole is difficult. This has the effect that the state of incomplete fitting is eliminated and a correct installation state can always be obtained.
