Description

DETAILED DESCRIPTION OF THE INVENTION <Field of the Invention> The present invention relates to a mounting structure of a control device for fixing a timer device or the like in a panel in an embedded manner.

<Prior Art and its Problems> Generally, in a control device such as a timer device, as shown in FIG. 4, a front flange portion 10 is formed in a mounting hole 102 formed in a panel 101.
The device main body 103 having 3a is embedded in the device main body 103, and the connecting piece in the U-shaped mounting member 104 including a pair of facing piece parts 104a and 104b and connecting piece parts 104c along both side surfaces of the device body 103. The part 104c is screwed to the rear surface 103b of the device main body 103 with the screw bodies 105 and 105, and the panel 101 is sandwiched between the respective front ends of the opposite piece parts 104a and 104b and the front brim part 103a. The body 103 is fixed to the panel 101.

However, in the means using the U-shaped mounting member 104, since the rear surface 103b of the device body 103 is transversely covered by the connecting piece portion 104c of the mounting member 104, this rear surface 103b cannot be effectively used. There is a drawback that the position and shape of the terminal portion (not shown) and the like provided on 103b are restricted.

For this reason, conventionally, there is a device using a pair of L-shaped mounting members 106, 106 as shown in FIG. That is, each bent piece portion 106a formed on one end side of both mounting members 106, 106 is screwed to the rear surface 103b of the device body 103, and the other end side tip surfaces of both mounting members 106, 106 and the front flange portion 103a of the device body 103. There is a panel 101 sandwiched between and.

In the means using the L-shaped mounting members 106, 106, the rear surface of the device body 103 is larger than that using the U-shaped mounting member 104.
The space of 103b can be effectively used, but when screwed, the other end sides of both mounting members 106, 106 expand outward (in the direction of the arrow) as shown in FIG. 5, and a proper mounting state is obtained. There are problems such as difficulty.

That is, when the other ends of the two mounting members 106, 106 expand outward, not only the mounting members 106, 106 become substantially shorter in length, but also the contact position and the contact direction with respect to the panel 101 change. As a result, the both mounting members 106,
The force for sandwiching the panel 101 between the tip end surface of the other end side of 106 and the front flange portion 103a of the device body 103 becomes weaker than in the regular mounting state, and the mounting state of the device body 103 to the panel 101 becomes unstable. .

In such an unstable mounting state, for example, the panel
If the hole diameter of the mounting hole 102 of 101 is slightly larger than the outer diameter of the device body 103, the mounting position of the device body 103 moves due to time or vibration, etc. Rattling occurs.

On the other hand, conventionally, in order to prevent the other end sides of the both mounting members 106, 106 from spreading outward, the mounting member 10
A short piece (not shown) bent in an L shape is provided at the tip of each bent piece portion 106a, 106a of the 6, 106 so as to project in parallel with the long portion of the mounting member 106, 106, and the short piece is attached to the rear surface of the device body 103. It is known that a projection piece (not shown) protruding rearward from 103b is brought into contact with the projection piece (see Japanese Utility Model Laid-Open No. 59-149686).

However, the outward spread on the other end side of each of the mounting members 106, 106 is the bending angle of each bending piece portion 106a, 106a with respect to the mounting member 106, 106, each bending piece portion 106a, by the screw body 105, 105. The mounting accuracy of mounting the 106a on the rear surface 103b of the device body 103 is affected.

Therefore, as described above, the L-shaped short piece is bent at the tip of the bent piece 106a, 106a so as to project, and these short pieces are brought into contact with the projection on the rear surface 103b of the device body 103. However, even if it is attempted to prevent the other end sides of the both mounting members 106, 106 from spreading outward, this cannot be effectively prevented in reality.

Further, when the L-shaped short piece or the protruding piece is arranged on the rear surface 103b of the device body 103 in this manner, the rear surface 103 of the device body 103 is correspondingly increased.
A useless space is formed in b, the mounting structure becomes large in size, and the material and manufacturing process of the entire mounting structure increase, resulting in high cost.

On the other hand, conventionally, a groove portion (not shown) extending in the front-rear direction is formed on the outer surface of the device body 103, and both side portions of the mounting members 106, 106 are slidably fitted into the groove portion. Is known (see Japanese Utility Model Publication No. 57-14896).

According to the above configuration, since the mounting members 106, 106 are fitted in the groove portions, it is possible to prevent the other end sides thereof from expanding outward.

However, in order to prevent the other ends of the mounting members 106, 106 from spreading outward, the groove section formed on the outer surface of the device body 103 is formed in a key-shaped cross section, or the groove section is formed. If the cross section of the mounting member 106 is formed in a U-shape that is easy to manufacture, it is necessary to form the cross sections of both sides of the mounting members 106 and 106 into a key shape in order to provide a retaining structure for the groove. However, the mounting structure becomes complicated or large in size and expensive.

<Purpose of the Invention> The present invention was made in order to solve the above-mentioned problems of the conventional one, and firmly stabilizes the mounting state of the device main body to the panel, and the mounting structure of the control device is simple, compact and inexpensive. Is intended to provide.

<Structure and Effect of the Invention> In the mounting structure for a control device according to the present invention, a pair of L-shaped mounting members are used, and groove portions are formed on both side surfaces of the device body so that the front end reaches at least into the mounting hole. Then, on each of the other end sides of the both mounting members, there is formed a projecting piece which projects from the other end side tip surface and is engaged between the groove and the inner wall of the mounting hole. It is a thing.

According to the above configuration, since the protruding piece formed on the other end side of the mounting member is engaged between the groove and the inner wall of the mounting hole, the engagement causes the mounting member to expand outward. It is possible to effectively prevent the rush.

By preventing the spread of the mounting member, the mounting member is arranged substantially parallel to the outer surface of the device body and its substantial length variation is prevented. It becomes almost constant.

Therefore, the other end side tip surface of the mounting member and the front brim portion of the device body maintain the force for sandwiching the panel in a proper mounted state, and the mounted state of the device body on the panel is stabilized.

In particular, since the protruding piece is elastically formed by being cut and raised on the other end side of the mounting member, it is elastically engaged with the inner wall of the mounting hole, and the elastic reaction force causes the mounting member to move to the device. The device body can be firmly held by being pressed against the outer surface of the body, and the mounting state of the device body on the panel is further stabilized.

Further, the grooved portion formed on the outer surface of the device body has a cross section formed into, for example, a simple U-shape of a mold structure, and the projecting piece is engaged with the inner wall of the mounting hole of the device body. Therefore, the mounting structure is extremely simple, small, and inexpensive.

<Description of Embodiments> An embodiment of the present invention will be described below with reference to the drawings.
