Description

[Detailed Description of the Invention] The present invention relates to a mounting device for a plug-type earth leakage breaker, and in particular provides a mounting device that is easy to attach and detach, has improved reliability, has a drop-off prevention feature, and has a wire hook.

The installation state of a conventional plug-type earth leakage breaker of this type is explained by referring to FIG. After the plug-type earth leakage breaker is connected and fixed, the plug 10 connected to the tip of the electric wire 9 of the protected device 8 is inserted into the lower outlet socket and used. When the electric wire is touched or when a vibration shock is applied, the plug 10 or the plug 6 may be pulled out, stopping the power supply or causing an incomplete connection.

Moreover, if the force applied to the plug 10 is large and a couple of forces are applied, the plug-type earth leakage breaker may be damaged.

As a countermeasure against these problems, one end of the string 13 was tied to the hook ring 12 of the tightening band 11 provided at the base end of the plug, and the other end was tied to a nail driven into the wall, as shown in Figure 1. As is well known, there are many types of plugs for protected equipment, including ones that do not have the above-mentioned provisions, or are impracticable, or the plug-type earth leakage breaker is not fixed, making it difficult to protect against vibrations, shocks, etc. The effect of preventing incomplete contact between the built-in plug 6 and the built-in receptacle 4 and preventing them from falling off is not improved.

The present invention solves the above-mentioned conventional drawbacks and provides a plug-type earth leakage breaker that improves connection reliability, prevents falling off, is easy to attach and detach, and has a wire hooking part.The present invention is implemented as follows. Let's discuss an example.

Referring to FIGS. 2 to 4, reference numeral 21 denotes a decorative board that covers the existing outlet by exposing only the receptacle 24 of the existing outlet 23 embedded in the wall surface 22, and the decorative board mounting screws 25a, 25
It is fixed to the wall by b.

26 is a plug-type earth leakage breaker, plug 27 into the power supply side.
An outlet receptacle 28 is provided on the load side, a convex portion 31 is provided on the outside of either the device stand 29 or the cover 30 (the cover in the embodiment), 32 is a handle for opening/closing operation, and 33 is a test button. It is.

34 is an electric wire with a protected device 35 connected to the load side and a protected device plug 36 connected to the power source side. The protected device plug 36 is inserted into the outlet receptacle 28, and is connected to the protected device 35. Supply power.

Reference numeral 37 denotes a fixture, which is formed into a U-shape consisting of a pair of vertical arms 38 and a bottom surface 39, and a hanging end 40 for hanging the convex portion 31 is attached to the free end at the center of the vertical arm 138. is provided with a hook part 41 for hooking the electric wire 34, a through hole 42 is provided in the bottom surface 39, and the fixture 37f is fixed integrally with the decorative board using the decorative board mounting screws of the existing outlet. ,.

Moreover, the pair of vertical arms 38 have elasticity from the outside to the inside.

The mounting method and the effects of the structure as described above will be explained below.

First, the mounting method for the fixture 3T is to connect the existing outlet to either the decorative board mounting screws 25a or 25b (in the example, 2
5b) is removed, the decorative board mounting screw is inserted into the through hole 42 on the bottom of the fixture, and screwed together with the decorative board.

Next, to install the plug-type earth leakage breaker 26, insert the plug 27 provided on the power supply side of the plug-type earth leakage breaker into either one of the sockets 24a, 24b (24a in the embodiment) of the existing outlet. As it is inserted, the convex portion 31 and the locking end 40 initially slide while overcoming the inward elastic force of the vertical arm 38 and spread the vertical arm outward.

When the plug is further inserted, the convex portion 31 and the locking end 40 are locked, and the plug 27 and socket 24a are completely inserted into the plug 1.
At the same time, the vertical arms of the fixture clamp and fix the plug-type earth leakage breaker by elastic force from the outside.

Next, after inserting the protected device plug 36 into the outlet receptacle 28, the electric wire 34 is hooked onto a wire hook provided at the free end of the vertical arm of the fixture, thereby completing the installation work.

In use, as is well known, tilt the handle 32 upwards,
Just turn it on.

Note that the test button 33 is used to confirm normal operation of the plug type earth leakage breaker.

In order to provide a mounting device for a plug-type earth leakage breaker as described above, even when an inadvertent tensile force is applied to the wire 34 connected to the protected device 35, the wire can be attached to the wire hook of the fixture. Since it is hooked, no tensile force is applied to the protected device plug 36, so it will not be pulled out or a state of incomplete contact will occur.

Similarly, the plug-type earth leakage breaker does not apply any pulling force or couple force to the plug-type earth leakage breaker, and it is possible to prevent not only incomplete contact but also damage due to falling off.

In addition, against vibrations and shocks, it is held by the elasticity of the vertical arm of the fixture and is fixed by the latching of the convex part and the latching end, which prevents incomplete contact and falling off from the socket. It is.

Furthermore, even if the button is pressed when trying to pull out the protected device plug 36 from the outlet receptacle 28, if the attachment is not used, a couple of forces will be applied to the plug 21, causing damage. By using the inventive mounting device,
It can be easily pulled out without applying force.

Next, when removing the plug-type earth leakage breaker, as shown in Figure 3, while lightly pinching the plug-type earth leakage breaker with your thumb and forefinger, push it in the direction of the vertical arrow.
8 are expanded outward from each other in the direction of the arrow, and the convex portion 31 and the locking end 40 are unlatched.

In this state, the plug-type earth leakage breaker can be easily removed by pulling it upward while holding it with both fingers.

As mentioned above, the present invention is a plug-type earth leakage breaker that can be easily attached and detached, improve connection reliability, and prevent fall-off and damage, eliminating the risks of unstable connections, falling off, and damage of conventional plug-type earth leakage breaker. This provides a mounting device for.
