Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a leg that is mounted on a housing of electronic equipment and a mechanism that holds a unit such as a printed circuit board.

[0002]

[Prior art]

 The conventional leg mounting structure used for housings of electronic devices is made by molding a material such as resin, and inserts a washer into a cylindrical leg that has a hole at the center and has a hole at the center. Fixed to the screw holes of the base, etc., or as another method, a plurality of locking claws formed to have elasticity on part of the legs are provided, and these locking claws are drilled in the base, etc. The general method of attachment is to lock and fix the holes. According to such a method, since the end of the screw or the locking claw used for fixing the leg is projected into the inside of the housing, the arrangement and shape of the unit such as the printed circuit board arranged in the housing However, there are restrictions related to the design of electronic devices, such as the need to provide a holding metal fitting for arranging these units in the housing at a position other than the position where the legs are attached. It was

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of such a point, and also has the function of fixing the legs and holding a unit such as a printed circuit board by engaging the holders with the legs mounted on the base or the like. A leg with a holding mechanism is provided.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention solves the above-mentioned problems by using a leg insertion hole formed in a base of a casing, a rectangular tube-shaped leg portion having an upper end closed and a hole at its center, and an upper end of the leg portion. A leg body consisting of a mounting portion provided with a plurality of locking claws at the tip standing upright, a holding portion having a means for holding a unit such as a printed circuit board at the upper end, and the above-mentioned engaging member formed on the outer periphery of the approximate center. It consists of a retaining groove that engages with the pawl and a retainer that has a flange at the lower end that fits into the leg. Insert the attachment part of the leg into the leg insertion hole, and insert the attachment part into the attachment part. A holding tool is inserted and the locking claw is locked in the locking groove.

[0005]

[Action]

 With the above-described structure, according to the leg with the holding mechanism according to the present invention, when the leg mounting portion is pushed into the leg insertion hole of the base to mount the leg on the base of the housing, this mounting is performed. The edge of the leg mounting hole of the base comes into contact with one side of the part to tighten it, and when it is pushed further, it is expanded and inserted. Next, when the holder is inserted into the hole of the leg, the locking claw at the upper end of the mounting part is pushed and spreads out by the upper end of the holder, and when it is pushed further, the retaining claw at the upper end is held by the elasticity of the mounting part. The locking groove formed on the peripheral side of the tool is locked, and the flange at the lower end of the holder is closely fixed to one side of the rectangular tube-shaped leg part, and at the same time, one side of the mounting part is attached to the leg of the base. It is restrained by the outer edge of the hole and urges in the direction of tightening. Therefore, due to the elasticity of this mounting portion, the leg body is fixed in close contact with the leg insertion hole of the base, and the holder is fixed to the base through the leg body. Then, mount a unit such as a printed circuit board in the screw hole or clamper provided on the upper end of the holder.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 (A) and 1 (B) are sectional views showing a leg with a holding mechanism applied to the present invention. FIG. 2 is a sectional development view of FIG. FIG. 3A is a hole drilling diagram for mounting the legs with the holding mechanism, and FIG. 3B is a top view showing a state where the legs with the holding mechanism are mounted in the holes. In the figure, 1 is a leg body formed by molding a resin material, and the leg body 1 is composed of a leg portion 3 and a mounting portion 2. The leg portion 3 is closed at its upper end and has a hole at its center to expand toward the lower end. A square-shaped rectangular hole 6 is provided by opening. The mounting portion 2 is provided with a locking claw 5 whose upper end is formed in the shape of a projecting piece, and is erected on the support portion 4 at the upper end of the leg portion 3 to form a plurality of facing V-shapes. However, the thickness is varied so that a predetermined elasticity can be obtained in the facing direction. Reference numeral 7 denotes a holder made of metal or resin, which has a screw hole 9 or a clamper 10 for holding a unit 8 such as a printed circuit board at the upper end, and a square tubular square hole 6 of the leg portion 3 at the lower end. Is provided with a flange 11 which is fitted to the upper end, a rectangular side is formed from the upper end to the lower end, and a locking groove 12 having a sawtooth-shaped recess is formed at a predetermined position on the peripheral side. There is.

In the base 13 which is one side of the housing of the electronic device or the like, the leg insertion hole which is engaged with the side contacting the mounting portion 2 and the side contacting the side portion of the holder 7. When the mounting portion 2 is inserted by inserting 14 and then the holder 7 is inserted into the square hole 6 of the leg 1, the locking claw 5 is pushed by the upper end of the holder 7 and expanded. When it is opened and further pushed, one side of the mounting portion 2 abuts on one side of the leg insertion hole 14 which faces and is restrained to increase elasticity, and the locking claw 5 fits into the recess of the locking groove 12. The locking claw 5 urges the holder 7 toward the upper end due to the elasticity of the mounting portion 2, and as a result, the flange 11 moves into the square hole 6 of the leg portion 3. Since the side is urged in the direction in which it closely contacts the base 13, both the leg 1 and the holder 7 are fixed. Even if the screw holes 9 provided at the upper end of the holder 7 are tightened with screws 15 through the holes of a unit such as a printed circuit board, they are sandwiched on both sides of the leg insertion holes 14 facing each other. Since the mounting portion 2 that is fixed by fixing the holding member 7 and the other side of the leg insertion hole 14 sandwich the angular side portion of the holder 7, it does not run idle. Alternatively, as another method, a clamper 10 formed of the same material, for example, in the shape of an arrowhead, is provided on the upper end of the holder 7, and a hole or the like of the unit 8 such as a printed circuit board is inserted into the clamper 10 and mounted. Good.

[Effect of device]

 As described above, according to the leg with the holding mechanism according to the present invention, the leg is mounted on the base, and at the same time, it also has a mechanism for holding a unit such as a printed circuit board. Therefore, there is no need to provide a mechanism for holding the legs other than the positions where the legs of the prior art are provided, and this has the effect of reducing the size of the device as well as increasing the degree of freedom in the layout design.
