DE3109620A1 - Worldwide travel-plug adapter - Google Patents

Abstract

The worldwide travel-plug adapter is an electrical engineering commodity. There are four different plug-socket systems in the world which are not mutually interchangeable because of their different shapes and sizes. These are: 1) the American system, 2) the Commonwealth system, 3) the South European system, and 4) the German system. If someone is travelling to America with their electric razor or charger for a dictaphone of German origin, then they need an adapter. In order to avoid having to carry a multiplicity of adapters when travelling through different countries, I have invented the worldwide travel adapter. This adapter contains all four plug systems stated. If, for example, the traveller is in America, then he just needs to move the contact pins designated America (6) into the in-use position in order to be able to plug the adapter into an American socket, while the other contact pins remain in the retracted position in the adapter. If he now travels to a Commonwealth country, then the American contact pins are moved into the retracted position and the Commonwealth pins into the in-use position. The apparatus plug side of the adapter can accommodate all the plug systems, so that this adapter can be used anywhere in the world. <IMAGE>

Description

World - travel plug = Konstruktions'oeschreiburlg = 1. Introduction: So far on the market electrical adapter plug for: ir Wlwktrogeräte mit German plugs can only be used in certain countries.

If the traveler selects a country with a USA plug socket system (USA, Central and South America, Far East, Asia) he uses for this connector system manufactured adapter plugs. If the same person travels to one of the British Commonwealth countries, so he must have another adapter, since the USA adapter is there does not fit. A third adapter plug is used for the countries of southern Europe (France, Greece, Italy, Portugal, Spain) is necessary because there is another plug socket system there is common.

The world travel plug contains all three mentioned plug-socket-fits. In addition, all plugs common in the various countries fit in this adapter.- Thus, this adapter can be the only one on the used all over the world 2. Construction principle of the world travel plug (1): In the universal adapter (1) (Sheet 1) between the device plug (2) and the foreign socket (3) are open the like side - the contact pins for the USA Commonwealth and South Europe - socket systems and on the opposite side the socket fits for USA, Commonwealth and South office including Germany plug housed. The view of the The plug-in site (4) of the Welt-Reisestekker is on sheet 2 on the left and the view of the Device plug side (5) shown on the right.

The blade terminal contacts of the USA system are closest together and hit a tostand of 12.5 mm on average. They are in the drawing (sheet 2) labeled 1.

The thicker pin contacts (5 mm diameter) of the Commonwealth Connector systems have an average distance of 16mm and are on sheet 2 with II designated. D The thinner round pin contacts (4 mm) of the South Europe plug system hook a mean distance of 49 mm (as well as the German connector system with its 5 strong round pin contacts).

They are marked III on sheet 2.

The paired contact pins 1 - III are each at 60 ° to each other staggered (see sheet 2).

If you draw the line A between the contact pins, they are in each one Connector half 4 pins (one USA pin, one Commonwealth pin and one South - Europe pin). They form an electrical pole while the other three contact pins form the opposite pole in the second half of the connector.

In the adapter plug are in the opposite side. to the contact pins the provided socket systems (USA, Commonwealth, Southern Europe including Germany) (sheet 2, ('7erätesteckerseite (5)). Also the sockets - Systems I - III are again: angles offset from one another by 60 °.

Line A divides the intermediate piece into 2 halves, so that each half contains a USA, Commonwealth, and South Europe electrical outlet system. (The South Europe socket system is expanded to 5 mm, so that German device plugs fit into it).

Each contact pin on the socket side (4) in one half of the The adapter plug is in contact with the 3 socket systems on the device plug side (5) of the intermediate piece, so the electrical conductivity between the two Connector sides is manufactured0 3. Structure of the contact pins I. USA contact - pens a. The pins have a total length of 50.5 mm. The one making the contact Part of the pin has a length of 19 mm, a width of 3 mm and a thickness of 1 ama. On the socket side of the contact pins is a notch 3 mm deep and 1. (mm 3 width (= thickness of coins) embedded (see sheet 2) .On the opposite side the contact pin (6) goes into a cylinder with a diameter of 6.3 mm and 12.5mm length across. This cylinder is used to guide the contact pin in a Sleeve ilp intermediate piece.

At the end of the guide cylinder there is a guide nose (7) 2 mm wide and 2.5 mm high, which protrudes 3 mm beyond the cylinder.

A pin (8) with a single diameter is attached to the guide cylinder of 2 mm and a length of 19 mm. This guide pin is used to guide a Compression spring (9).

b. Each contact pin is located in a sleeve in the intermediate piece is adapted to the shape of the guide cylinder and the guide nose of the contact pin Guide rail for the guide nose is closed at the socket intermediate piece, so that the contact pin cannot be removed from the intermediate piece If you now press the pin into the intermediate piece (see 3latt 2), the spring is tensioned on the spring guide pin. At the end of the compression stretch, the pin hits against it the end plate (10) By turning the pin, the guide nose rotated out of the guide sleeve by 90 ° and thereby locked. So that is Contact pin retracted in the intermediate piece, so-called rest position. Should the contact pin g -.- are used, it is released from the lock by turning and Due to the spring pressure, extended from the intermediate piece into the so-called use position. In the extended state, the contact pin is locked again by rotating it through 90 ° by turning the guide nose out of the guide rail again.

c. In the extended state (use position) of the contact pin and only after it has been rotated by 90 ° does this have; Contact via a wetall plate to the socket systems on the device plug side (5) via the device plug contact disc (11) see sheet 2.

II. Commonwealth Contact Pins III. South Europe Contact Pins Die Contact pins of the Commonwealth and Southern Europe - Stcker systems are in the same way Wise and have the same functional processes as the USA contact pins the dimensions for the Deiden contact pin systems are taken into account.

4. Instructions for use The Welt travel plug serves as an adapter between the plug systems commonly used in the world and the various socket systems. E.g. (USA plug and German socket or Commonwealth plug and Southern Europe sockets.

For better orientation, the various systems are marked with FarZ ben marked: USh system = red; Commonwealth System - blue; South Europe system = light green.

For example, if the traveler is in the United States, a coin the red marked contact pins are released from the locking mechanism by turning them. They slide through the spring pressure out of the intermediate piece and are renewed by Rotation through 90 ° (position of use) locked. Now the intermediate piece can be sent to the USA - The socket outlet is pushed in. On the device plug side of the adapter the Device plug of the other plug system e.g. Commonwealth plug or South European plug inserted. This is the electrical connection between two different plug-socket systems manufactured. The advantage of this world travel adapter is that it a f the bug world can be used as an adapter.
