Definitions
- the invention relates to an adapter plug for a rechargeable electrical device equipped with flat plug pins for personal use, e.g. Dry shaver, with a plug housing with plug pins for connection to a socket and with a housing wall in which plug-in holes suitable for flat plug pins are provided for voltage transmission.
- these tabs are installed in different countries, in which such a plug system is installed nationwide in all households, also in electrical devices that are equipped with rechargeable memory cells, which can be pushed out and swung out of the device house, whereby The distances that the flat plug pins take to the outer walls of the connector housing or the outer walls of the electrical device are smaller than the plug contours prescribed in this regard in some countries, and thus the clearances and creepage distances at the user's hand.
- An electrical device of the type mentioned is known for example from the German utility model G 83 29 691 (IM).
- the device plug of the rechargeable shaver is slidably arranged at one end of the razor housing.
- the two leaf-like plug pins attached to a connector housing are pushed out of one of the two narrow sides of the razor housing by means of an actuation switch arranged in the base of the housing for connection to a socket of a voltage source.
- the socket can, for example, be fixed in a wall of a room in a house or be part of an adapter plug.
- Rechargeable electrical devices such as shavers of the aforementioned type are known to be provided with charging circuits for rechargeable memory cells, the voltage range of which is mostly from 90 to 270 volts.
- an adapter plug equipped with round plug pins is known, on the end wall of which is opposite the plug pins, a circumferential safety wall is provided.
- This adapter plug only permits the coupling of an electrical device with the aid of a mains cable equipped with flat plug pins, but not a direct coupling of a rechargeable electrical device equipped with flat plug pins.
- the object of the invention is to provide an adapter plug of the type mentioned in the introduction, in which the coupling of a rechargeable electrical device equipped with flat plug pins is ensured, taking into account a sufficient safety distance.
- this object is achieved with an adapter of the type mentioned in that the insertion holes are assigned at least one safety wall protruding from the housing wall in such a way that the distance between the insertion holes or the flat plug pins of the electrical device and the safety wall during the coupling of the flat plug pins with the insertion holes is at least equal to or greater than the safety distance to be observed to prevent a flashover
- a major advantage of the invention is that an adapter plug that meets the safety regulations is only created by redesigning and otherwise arranging an existing safety wall.
- the adapter plug according to the invention as the exemplary embodiments according to FIGS. 3 and 4 show, can be produced more cheaply due to the material savings.
- the safety wall is cylindrical and is provided with a U-shaped recess for coupling the intermediate plug to the flat plug pins of the electrical device.
- the security walls are provided on the housing wall parallel to one another.
- the distance between opposite safety walls equals the distance between two opposite walls or the thickness of the electrical device to be accommodated.
- the distance between opposite safety walls can be made somewhat larger than the distance between two opposite walls or the thickness of an electrical device to be accommodated.
- FIG. 1 shows an embodiment of a known intermediate connector with round connector pins and slot-like insertion holes in a flat end wall
- FIG. 2 shows a known adapter plug with round plug pins and with slot-shaped insertion holes and an annular safety wall on the end wall opposite the round plug pins,
- FIG. 3 shows an adapter plug with a cylinder-like safety wall with a recess and a razor equipped with flat plug pins for coupling with an adapter plug
- Fig. 4 shows an adapter plug protruding from an end wall
- Round plug pins and safety walls provided on the opposite end wall as well as slot-like insertion holes.
- FIG. 1 an adapter plug of a known type is shown.
- the adapter plug consists of a cylindrical connector housing 1, which is closed on the front side by housing walls 20 and 30.
- Two round connector pins 2 and 3 protrude from the housing wall 20, while 30 insertion holes 4 and 5 are provided in the opposite housing wall.
- the insertion holes are slot-like for receiving flat plug pins, a voltage flow from the round plug pins 2 and 3 to the flat plug pins located in the insertion holes 4 and 5 being ensured in the interior of the plug housing 1 by means of electrically conductive components.
- FIG. 2 another adapter of known type is shown, the structure of which corresponds essentially to the known adapter of Fig. 1. The only structural difference is that the housing wall 30, which is essentially flat, is assigned an annular safety wall 6.
- Fig. 3 shows an adapter plug with a connector housing 1, two round connector pins 2 and 3, and two provided in the housing wall 30, suitable for coupling with the flat connector pins 1 1 and 12 of an electrical device 10 insertion holes 4 and 5 and a circumferential security wall 7 the from a U-shaped recess, the leg of which is interrupted by the flat housing wall 30 and the edges 71 and 72 of the safety wall 7.
- a dry shaver is also shown as a loadable electrical device 10.
- the two sheet-like fastened to a connector housing 14 tabs 1 1 and 1 2 are pushed out of one of the two narrow sides of the razor housing for connection to the adapter plug and locked in this position by means of an actuating switch 13 arranged in the housing bottom 15.
- the thickness B1 of the narrow side of the electrical device 10 is slightly smaller than the distance A1, the safety walls 8 and 9 formed by the U-shaped recess in the safety wall 7, so that in the course of the coupling process the flat pins 1 1 and 12 of the electrical device 10 with the Insertion holes 4 and 5 in the connector housing 1 of the adapter plug ensure that the user performing the insertion process can neither get in touch with the flat plug pins 1 1 and 1 2 nor in the vicinity thereof.
- the rechargeable electrical device 10 is pushed with the flat plug pins 11 and 12 into the insertion holes until a wall of the electrical device or a wall of the plug housing 14 comes to rest against the housing wall 30.
- Fig. 4 shows an adapter plug, the structure of which corresponds essentially to the adapter plug according to Fig. 1.
- two safety walls 8 and 9 are provided on the adapter plug according to FIG. 4 on the housing wall 30, which are preferably molded onto the connector housing wall.
- the two opposite security walls 8 and 9 form in connection with the housing wall 30 a U-shaped fork, which is basically the Inclusion and coupling of electrical devices equipped with tabs 1 1 and 1 2 1 0 guaranteed.
