Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents a plug connected to a plug seat (hereinafter referred to as "inlet") for supplying AC power to an AC cord fixing device, particularly, an electric device or the like, from falling off from the inlet. The present invention relates to an AC cord fixing device.

[0002]

2. Description of the Related Art In many electronic devices such as communication devices, a plug receiver is provided on a device housing side, and an external insertion plug is inserted into the plug receiver and connected to an external power supply. In this type of electronic device, it is necessary to provide a stopper on the insertion plug so that an operator may erroneously hook a cable around the device during operation of the device so that the insertion plug does not come off the plug receiver.

[0003] A conventional AC cord fixing device will be described in detail with reference to the drawings.

FIGS. 3A and 3B are a perspective view and a side view showing a first conventional example. In the figure, 101 is a housing, 102
Is a plug receiver, 103 is a plug cable, 104 is a locking tool, and 105 is a mounting tool. The housing 101 has an opening 109 formed in the rear surface 108, and the plug receiver 102 is positioned in the opening 109 and attached to the housing 101.

The plug cable 103 is connected to the plug 11
1 and a cable 112 connected thereto are integrally formed of resin and formed.

The attachment 105 is formed of an L-shaped sheet metal, and has a screw hole 116 to be screwed with the screw 114. The attachment 105 is fixed to the housing bottom surface 118 with screws 119 below the plug receiver 102.

The locking member 104 is made of sheet metal, has a notch 121 into which the base 120 of the insertion plug 111 is inserted, and has an upper end bent to form a claw 122. At the lower end, a notch 124 into which the screw 114 is inserted is formed. The locking member 104 is connected to the housing 101 by a chain 125 so as not to be lost.

After the insertion plug 111 is inserted into the plug receiver 102, the locking tool 104 has a notch 121 at the upper end.
Is inserted into the base portion 120 of the insertion plug 111, and the lower end portion is screwed to the fixture 105. Therefore, the plug 11 inserted in the plug receiver 102
In the case 1, since the movement in the direction opposite to the insertion direction (the direction of arrow a) is prevented by the locking member 104, even if the operator accidentally hooks the cable 112, the plug holder 102 is not used. It will not come off.

However, according to this structure, the screw 1
Since the attachment / detachment of the locking tool 104 is performed using the 14, a tool such as a driver is required, so that the work of attaching / detaching the locking tool 104 is complicated. In particular, when the device is installed in a state where there is no space on the side of the device rear surface 8, tools such as a screwdriver cannot be used.
04 cannot be attached or detached.

Are formed, and the plug receiver 202 is provided with the opening 209.
And attached to the housing 201.

The plug cable 203 is connected to the plug 21
1 and a cable 212 connected thereto are integrally formed with resin to be formed.

When power is supplied to the electronic device, the plug 211 is inserted into the plug receiver 202 in the direction of arrow b.

The attachment 231 is formed by bending a sheet metal into an L-shape, and below the plug receiver 202, one part 233 of the attachment 231 is attached to the bottom surface 218 of the housing.
Is fixed with screws 236. The other portion 234 bent at a right angle to the portion 233 projects upward.

The locking member 230 is composed of two metal plates 237 and 238.
And a notch 240 into which the base 220 of the insertion plug 211 is inserted is formed at the upper part. Further, the metal plates 237 and 238 constituting the locking member 230 are provided.
The upper ends of the claw portions 24 are bent in a direction away from each other.
2 and a claw portion 243 are formed.

On the other hand, a sheet metal 23 is
7, 238 form a slit-like groove 245 into which the portion 234 of the attachment 231 is fitted. In order to prevent the locking member 230 from being lost, this locking member 230 is
01 by a chain 246.

However, a screwdriver is required for screwing both ends of the plug retainer to the electronic device side,
In an emergency, when you want to unplug immediately from the outlet and turn off the power, you cannot immediately unplug. In addition, in the method of fitting the retaining member of the plug into the mounting member on the bottom portion of the housing, since the retaining member is not fixed, when the plug is removed from the outlet, the retaining member may be lost, It cannot be adopted when it is necessary to stop again.

FIG. 5 is a perspective view showing a third conventional example.
(See, for example, JP-A-09-147980).

The locking member 305b is hooked on the insertion plug cover 306a of the insertion plug 306, and
The hinge spring 304 is wound around the hinge rotation shaft 303a, the hinge fixed side 303, and the hinge rotation shaft 303a connected to the hinge spring 304. Then, the insertion plug 306
After the plug is inserted into the outlet, the locking tool 305 b presses the plug 306 with the hinge spring 304.
Thereby, the attachment / detachment work of the locking member 305b for preventing the insertion plug 306 from coming out of the outlet can be easily performed.

FIGS. 6 (a) and 6 (b) are a perspective view and a sectional view showing a pattern in an unlocked state in the third prior art. The state where the hinge movable side 305 is covered up to the surface of the outlet flange portion 307 is shown. Plug 30
When the hinge 6 is disconnected from the outlet main body 307a, the hinge movable side 305 is rotated and stopped by the force of the hinge spring 304 until the hinge movable side 305 hits the outlet flange portion 307.
A latch 305b integral with the hinge movable side 305 enters the square back hole 301a opened at the bottom of the housing back part 301,
When the insertion plug 306 is not locked, it is structured to enter the inside of the housing. In order to lift the hinge movable side 305, the hinge movable side 305 can be rotated upward with the hinge cut-and-raised portion 305a. The hinge movable side 305 provides the effects of erroneous connection from outside and terminal protection.
