Abstract

(57) [Summary] [Purpose] The barrier fixing device for protection used in various electronic devices solves the bending and bending of the claws, and makes it quick and easy for workers and servicemen to attach and detach. Aiming at a barrier fixing device with excellent properties that can be achieved. [Constitution] "U-shaped" at the base of the "U-shaped" notch
Fold it in and make a hook 3 of triangular shape. By bending the hook 3 so that the bending height is about 1 mm higher than the width of the long hole formed in the mounting plate, the hook 3 will be caught by the mounting plate after being inserted into the long hole, so that the mounting work can be performed securely. I can.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protective barrier fixing device used in electronic equipment.

[0002]

[Prior Art]

 The conventional barrier fixing device shown in FIG. 2 will be described below.

In FIG. 2, 1 is a fixing plate, 2 is an elongated hole into which a barrier fixing device is inserted, and 3 is a claw portion in the barrier fixing device. Numeral 4 is a slit for absorbing the "deflection" of the nail when inserting the barrier fixing device into the long hole of the fixing plate.

The following operation of the barrier fixing device configured as described above will be described. The length of the long hole 2 provided in the fixed plate 1 is set to be smaller than the width of the claw 3 by about 1 mm. The claw 3 is forcibly inserted into the long hole 2 provided in the fixed plate 1. At that time, the claw 3 is bent by being inserted from both sides. The deflection is absorbed by the slit portion 4 and passes through the long hole 2 portion, and when it completely passes, the claw returns to its original shape by elasticity and is fixed to the fixing plate.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional structure, since the slit for absorbing the "bend" in the center of the claw part is provided, the base of the claw part becomes thin, the strength of the claw becomes weak, and it is forcibly inserted into the long hole of the fixing plate. In this case, (1) the base of the claw is broken or bent, and does not serve as a fixing device. (2) Care must be taken when inserting the nail so that it will not break. (3) At the time of removal at the time of service, I could not use it because I broke my nail.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a barrier fixing device that can be easily attached by an operator or a service person.

[0007]

[Means for Solving the Problems]

 In order to achieve this object, the barrier fixing device of the present invention eliminates the central slit of the claw and increases the strength of the claw root. Further, in the past, since the "warm" in the direction perpendicular to the thickness of the sheet was used to insert it into the hole of the mounting plate, the base of the claw was plastically deformed and bent. According to the present invention, since the "deflection" in the thickness direction of the sheet is used to insert the "deflection" within the elastic limit, plastic deformation does not occur. The claws have a trapezoidal shape with the tip slightly narrower than the root to facilitate insertion, and the "U" -shaped notch that connects the barrier body and the claws Bend it in and form a hook with a triangular shape. The hook portion is bent at a height that is about 1 mm higher than the width of the long hole formed in the mounting plate, and the hook portion is used to fix the barrier body.

[0008]

[Action]

 With this structure, the barrier body is fixed by inserting the claw into the elongated hole of the fixing portion provided on the fixing plate. A part of the trapezoidal claw is bent into a "V-shape", and the height of the hook is set about 1 mm higher than the width of the slot, so the claw part completely passes through the slot. After that, the height of the hook part of the "he-shaped" claw part returns to the original height, and the hook part of the "he-shaped" is caught on the fixing plate by about 1 mm, and the barrier body can be fixed.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a mounting plate, 2 is an elongated hole into which a barrier fixing device is inserted, and 3 is a claw of the barrier fixing device.

The operation of the barrier fixing device configured as described above will be described with reference to FIG. First, the claw 3 is inserted into the elongated hole 2 provided in the mounting plate 1. When the claw passes through the long hole 2 part, the bending height of the hook part provided on the claw 3 is 1 mm larger than the width of the long hole 2 part. It is compressed in the width direction of the slot. After being completely inserted, the hook portion of the claw 3 returns to its original height, and the hook portion of the "to" is caught on the fixing plate, so that the barrier body is securely fixed.

[0012]

[Effect of the device]

 As described above, according to the present invention, by providing the hook portions in which the both ends of the fixed claw portion are bent in the shape of “V-shape”, the installer or service person does not break the claw portion and can quickly It is also possible to realize an excellent barrier fixing device that can be easily attached.
