Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a housing structure of an electronic device, and more particularly to a structure for housing and fixing an internal unit.

[Prior Art] Conventionally, this type of housing structure has been used for a structure for fixing a keyboard unit such as a telephone set. FIG. 2 is a cross-sectional view of an example thereof, in which the keyboard unit 1 and the key sheet 2 are supported by the cover 3, and the cover 3 is fitted in the case 4. In this case, the cover 3 integrally has a pair of hook-shaped ribs 5, and the keyboard unit 1 and the key sheet 2 are engaged with the hook portions 5a of the hook-shaped ribs 5 to support them. There is.

[Problems to be solved by the device]

In the above-described conventional housing structure, the hook-shaped rib 5 that supports the keyboard unit 1 and the key sheet 2 is configured as a hook of the one-end supporting structure, so that when the key sheet 2 is pushed with a large force, the hook-shaped rib 5 The rib 5 bends outward,
There is a problem that the keyboard unit 1 comes off from the hook-shaped rib 5.

Further, in order to prevent this, if the thickness of the hook-shaped rib 5 is increased to make it difficult to bend, then there is a problem that it becomes difficult to assemble the keyboard unit 1 to the cover 3 this time.

An object of the present invention is to provide a housing structure capable of solving the above-mentioned contradictory problems at the same time.

[Means for Solving the Problems]

The housing structure of the present invention is such that a case in which an internal unit such as a keyboard and a key sheet is housed is inserted into a gap between a back surface of a hook-shaped rib for supporting the internal unit on a cover and the cover. Stopper ribs are provided to prevent deformation of the mold ribs.

[Action]

With this configuration, when the cover and the case are fitted together, the stopper ribs intrude between the back surface of the hook-shaped rib and the cover to prevent the hook-shaped rib from being deformed and prevent the internal unit from falling off.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of an embodiment of the present invention, in which a keyboard unit 1 is supported by a cover 3 together with a key sheet 2, and the cover 3 is fitted in a case 4. Further, a pair of hook-shaped ribs 5 are integrally provided inside the cover 3, and the keyboard unit 1 and the key sheet 2 are engaged with and supported by the hook portions 5a thereof.

Here, a slight gap is provided between the back surface of the hook-shaped rib 5 and the inner surface of the cover 3, and the stopper rib 6 integrally provided in the opening of the case 4 is inserted into this gap. Is configured. The thickness of the stopper rib 6 is substantially equal to or slightly smaller than the gap between the hook-shaped rib 5 and the cover 3.

According to this structure, in the state before the cover 3 is fitted into the case 4, the hook portion 5a of the hook-shaped rib 5 is easily deformable, and the hook-shaped ribs 5 are deformed outward respectively to the keyboard unit. The key sheet 1 and the key sheet 2 can be fitted between the hook-shaped ribs 5 to easily support them.

Then, when the cover 3 and the case 4 are fitted together,
The stopper rib 6 provided on the case 4 is inserted into the gap between the hook-shaped rib 5 and the cover 3 to prevent the hook-shaped rib 5 from being deformed outward. Therefore, even when a large force is applied to the key sheet 2, it is possible to prevent the hook-shaped rib 5 from being deformed outward and the keyboard unit 1 from falling off from the hook-shaped rib 5. While this facilitates support,
Eliminates the contradictory problem of increasing support strength.

The present invention can be similarly applied to the case where an internal unit other than the keyboard and the key sheet is installed inside the housing.

[Effect of device]

As described above, according to the present invention, since the case is provided with the stopper rib for preventing the deformation of the hook-shaped rib by penetrating into the gap between the hook-shaped rib for supporting the internal unit and the cover, the cover and the case are not provided. At the time of fitting, the stopper rib enters between the hook-shaped rib and the cover to prevent the hook-shaped rib from being deformed and prevent the internal unit from falling off. Therefore, if the hook-shaped rib is configured to be easily deformed, the internal unit can be easily supported, while the internal unit can be effectively prevented from falling off when it is installed inside the case.

Claims (1)

[Scope of utility model registration request] 1. A deformable hook-shaped rib projectingly provided in a cover supports an internal unit such as a keyboard and a key sheet, and the cover is fitted into the case so that the internal unit is internally provided in the case. In the case of electronic equipment,
A gap is provided between the inner side surface of the cover and the back surface of the hook-shaped rib, and when the cover is fitted into the case, the clearance penetrates into the clearance and the hook-shaped rib is deformed in the back surface direction. A housing structure for an electronic device, which is provided with a stopper rib for preventing this.
