DE102012000617A1 - Socket protecting device for protecting child and infant from live contacts with socket, has central bore mechanically fastened to socket by screw, where device is fastened to socket by aging-resistant double-sided tape - Google Patents

Abstract

The device (1) has housing, a rotatable disk (3), a rear wall (4), a helical spring (9) and a central bore that is mechanically fastened to a socket by a screw (7). The device is fastened to the socket by an aging-resistant double-sided tape, and the helical spring generates an evasive action during unilateral loading of the rotatable disk, and causes locking of hooks of the rotatable disk with a barbed hook of the housing. The housing includes conically formed springy ribs on flattened outer surfaces, where the ribs fix the device in guiding grooves.

Description

Description of the Related Art:

Currently, there are a variety of socket fuses to prevent infants to play on sockets with an object, thereby making an electrical contact and take damage.

• a. einer Kappe, die in die Steckdose eingesteckt wird und die diese verschließt.
• b. einer Doppelscheibe, gegeneinander verdrehbar mittels eines Steckers, wodurch die Steckkontakte frei gegeben werden. Wird der Stecker herausgezogen, so dreht sich die unter Federspannung stehende Scheibe wieder zurück und verschließt damit wieder die Steckkontaktlöcher.
• c. Wie b., jedoch sind die Scheiben gegeneinander verschiebbar. Vor dem Einstecken des Steckers muss eine Scheibe so weit verschoben werden, bis die Steckkontaktlöcher freigegeben werden. Zum Zurückschieben wird ein Gummi-/Kunststoffring-Feder verwendet.
• d. Die Doppelscheiben nach b. und c. werden in die Steckdose eingeklemmt oder eingeklebt.

Socket fuses with different methods are used for this protection. These include socket fuses preferably made of plastic in the form

• a. a cap that is plugged into the socket and closes it.
• b. a double disc, against each other rotatable by means of a plug, whereby the plug contacts are released. If the plug is pulled out, the spring-loaded washer rotates back again, closing the plug contact holes again.
• c. Like b., But the discs are mutually displaceable. Before inserting the plug, a disk must be moved until the plug-in holes are released. To push back a rubber / plastic ring spring is used.
• d. The double discs after b. and c. are pinched or glued into the socket.

Object of the invention

• – ein spielendes Kind kann mit einem einzelnen Gegenstand (Stift; Kuli, Nagel usw.) die stromführenden Kontakte in einer Steckdose erreichen.
• – Kleberalterung durch ungeeigneten Kleber
• – Gummi-/Kunststoffring-Federalterung
• – nachlassende Klemmwirkung durch Kaltfluß der Kunststoffteile
• – ein Nicht-abdecken der Steckerlöcher in der Steckdose bei einseitiger Belastung
• – Steckdosensicherung wird beim Herausziehen des Steckers aus der Steckdose ebenfalls mit heraus gezogen

The object of the invention is to develop a socket fuse which avoids the following disadvantages:

• - A playing child can reach with a single item (pen, pen, nail, etc.) the live contacts in a socket.
• - Adhesive aging due to unsuitable adhesive
• - Rubber / plastic ring riveting
• - Decreasing clamping effect due to cold flow of the plastic parts
• - Do not cover the plug holes in the socket with one-sided load
• - Socket fuse is also pulled out when pulling the plug out of the socket

Solution of the task

• 1. Fastening the socket fuse Through a centrally located screw and / or with a special, long-term durable, age-resistant double-sided tape, the socket fuse is mounted in the socket.
• 2. Material fatigue Replace rubber and / or plastic ring spring with one or more eccentric metal coil springs in the middle.
• 3. Closing the socket with one-sided force approach The freely rotatable between the housing and the rear wall, the plug holes closing or releasing turntable is provided with corresponding hooks that easily hooked into corresponding barbs in the housing by tilting / twisting.

Description of the solution / function

• 1. Fastening the socket fuse
• a. The socket fuse 1 receives centrally located a screw hole 5 , Every outlet 6 has a centrally located screw 7 holding the socket together. This screw 7 can easily be screwed out by the professional. After that, the socket fuse 1 into the socket 6 inserted. By means of the screw 7 becomes the socket fuse 1 in the socket 6 attached. This is an accidental removal or falling out of the socket fuse 1 from the socket 6 locked out.
• b. The mechanical fastening by means of screw 7 can by a special, non-aging double-sided tape 8th which is between socket 6 and socket fuse 1 is arranged, replaced / supported.
• 2. The out of the case 2 , the turntable 3 and the back wall 4 existing socket fuse 1 receives a centrally or more eccentrically arranged coil spring 9 , The coil spring 9 cause the turntable 3 twisted on one-sided load and / or pushed out of the middle. The dimensions for the columns are between hooks 10 and barbs 11 kept very tight. Because the turntable 3 hook on its outer surface 10 has, in the case of twisting and / or moving in barbs 11 of the housing 2 will intervene, opening the socket holes 12 prevented by a child playing. You push the turntable 3 however, with a 2-pin standard connector in parallel, in the middle in the direction of the open position 12 so can the socket fuse 1 at the barbs 11 pushed into its open position and plugged in the plug.
• 3. The plug holes 13 the turntable 3 be below the plug holes 14 the socket 6 arranged so that the connector holes 14 the socket 6 even in case of breakage of the coil spring 9 through the falling down turntable 3 stay closed.
• 4. The coil spring 9 has enough spring force to close the plug holes 14 the socket 6 through the turntable 3 to guarantee.
• 5. The socket fuse 1 gets at the flattened outer surfaces of the housing 2 conical, resilient ribs 14 , which is a correct position socket fuse 1 in the guide grooves 15 the standardized socket 6 cause. This is a twisting of the socket fuse 1 in the socket 6 prevented. The function of hooking the turntable 3 or the precise guide to the barbs 11 of the housing 2 over is guaranteed.

Claims (4)
