Description

[Detailed Description of the Invention] The present invention relates to an improvement of a mounting device for a so-called plug-type earth leakage breaker, in which the power supply side is a plug, and the load side is an outlet or a cord.

The applicant of this application previously filed application No. 169 for utility model registration in 1978.
In No. 200, we proposed a plug-type earth leakage breaker mounting device that is easy to install and remove, improves connection reliability, prevents falling off and damage, and doubles as a wire hook.

However, as stated in the specification of Utility Application No. 52-169200, this was perfect for protection against the cord being pulled or vibration or shock being applied to the plug-type earth leakage breaker; For example, even if installer A installs a plug-type earth leakage breaker to protect a certain device, such as a vending machine, from electric leakage, installer B can install an electric device, such as an electric drill, that he or she uses. This plug-type earth leakage breaker may be temporarily borrowed for protection, and as a result, the earth leakage breaker must be removed, even temporarily, from equipment that should be protected from earth leakage on a regular basis.
In some cases, the purpose of installing a plug earth leakage breaker was not fully achieved.

In view of the above points, this invention improves the reliability of the connection,
To provide a mounting device for a plug-type earth leakage breaker that prevents falling off and damage, doubles as a wire hook, is easy to install, and is not easy to remove.

In Figures 1 and 2, reference numeral 1 denotes a decorative board that covers the existing outlet by exposing only the receptacle 3 of the existing outlet 2 embedded in the wall, and is fixed to the wall using decorative board mounting screws 4a and 4b. There is.

Reference numeral 5 designates a plug-type earth leakage breaker, which has a plug plug 6 on the power supply side, a lower outlet socket on the load side, and a convex latching portion on the outside of either the device stand 8 or the cover 9 (the cover in the embodiment). 1
0 is provided, and the device base is provided with a tongue-like protrusion 24 having a hole 25 through which the breaker fixing screw 26 passes.
1 is a handle for opening/closing operation, and 12 is a test button.

Reference numeral 13 denotes an electric wire with a protected device 14 connected to the load side and a protected device plug 15 connected to the power source side.
5 is inserted into the outlet receiving lower, and the protected device 14
to supply power.

Reference numeral 16 denotes a fixture, which consists of a pair of vertical arms 17 and a fixing end 21 having a tapped hole 22 into which a fixing screw 26 passing through the hole 25 is tightened. A hooking end 23 for hooking the shaped portion 10 is provided at the free end with a hooking portion 19 for hooking the electric wire 13, and a through hole 20 is provided at the connecting portion 18 between the vertical arm 17 and the fixing end 21. , using the decorative board mounting screws of the existing outlet, install the fitting 1.
The fixture 16 is fixed integrally with the decorative board using decorative board mounting screws 6, and the pair of vertical arms 17 have elasticity from the outside to the inside 15.

In the structure configured as above, the mounting Jj method and the effects will be explained below.

First, to install the fixture 16, remove one of the decorative board mounting screws 4a and 4b (4b in the example) from the existing outlet, and insert the decorative board mounting screw into the through hole 20 on the bottom of the fixture. Then, screw together with the decorative board.

Next, to install the plug-type earth leakage breaker 5, insert the plug 6 provided on the power supply side of the plug-type earth leakage breaker into either the socket 3a or 3b (3a in the embodiment) of the existing electrical outlet I. When you insert it into the
While sliding, overcomes the inward elastic force of the vertical arms 17 and spreads the vertical arms outward.

As the fitting is further inserted, the convex portion 10 and the locking end 23 are locked, the plug 6 and the socket 3a are completely inserted, and the vertical arm of the fitting is shaped into a plug shape by the elastic force from the outside. Clamp and secure the earth leakage breaker.

Next, the breaker fixing screw 26 is passed through the through hole 25 of the tongue-like projection 24 provided on the plug-type earth leakage breaker and tightened into the screw hole 22 provided on the mounting base.

Thereafter, after inserting the protected plug 15 into the outlet receptacle 17, the electric wire 13 is hooked onto the electric 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 11 upwards,
Just turn it on.

Note that the test button 12 is used to confirm normal operation of the plug type earth leakage breaker.

1-. By providing a fixing device for the plug-type earth leakage breaker as described above, even if an inadvertent tensile force is applied to the wire connected to the protected device 14, the wire can be secured to the wire hooking part of the fixture. Although it is hooked, no tensile force is applied to the protected device plug 15, so it will not be pulled out or a state of incomplete contact will occur.

Similarly, the attachment means that no pulling force or couple force is applied to the plug-type earth leakage breaker, making it possible to prevent not only incomplete contact but also falling off and damage.

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.

Further, since the fixture 16 and the plug-type earth leakage breaker 5 are fixed to the spring 24, they cannot be easily removed.

Therefore, if a third party mistakenly uses a plug-type earth leakage breaker installed to protect equipment to protect other equipment,
There is no possibility that you will not be able to protect your equipment as planned.

Also, if you use a padlock instead of 24, it will also prevent theft.

On the other hand, if the plug-type earth leakage breaker is frequently installed and removed, it can be easily installed and removed as in the conventional case without using the wand 24.

As described above, the present invention provides a fixing device for a plug-type earth leakage breaker that is inexpensive, easy to install, and is not easy to remove, and can prevent the plug-type earth leakage breaker from being easily moved or stolen. This has a great effect.
