Technical Field
The invention relates to a travel adapter plug (also called travel plug). With the aid of such a changeover plug, a power plug of some (domestic) standard can be plugged into an outlet at the travel site. To this end, travel conversion plugs require a first standard outlet or an alternative power source (e.g., via a cable) and another standard power plug. The invention relates more particularly to a travel conversion plug which is capable of inserting at least one first and one second standard plug into a socket. For the travel conversion plug, first and second standard power plugs may alternatively be used.
Background
In an era of global travel and increasing business activities, travel conversion plugs or travel plugs of this type are increasingly used. Therefore, there is a need for a compact, easily transportable travel conversion plug that is adaptable to several different standard outlets.
Chinese patent application CN101872911A discloses a travel conversion plug with a substantially circular housing. The power plug is arranged in the shell and can be selectively pushed out of the shell. In this manner, at least three different types of power plugs can be used. The desired power plug is selected by rotating the upper portion of the housing relative to the lower portion of the housing. The upper portion of the housing has an outwardly projecting actuator button. The actuation button is engageable with various power plug components. For this purpose, it is rotated to a position above the power plug to be pushed out of the bottom of the housing.
Such travel plugs may be used for many purposes. However, it would be desirable to provide a travel plug that is easier to operate and that may also have a rectangular design.
German patent specification DE 102011014920B 4 discloses another travel plug, which is referred to as a universal conversion plug. The travel plug has multiple sets of prongs in an outer housing. Each set of pins is connected to a control panel by which each set of pins is movable from the outside. For this purpose, the operating element is guided by a slide groove in the housing. The control is also guided by a locking plate in the outer housing. The locking plate has a guide rail, through the groove of which the operating element can be moved. The locking plate has an upper end position and a lower end position. The locking plate is spring loaded so that the control panel can be held firmly in either the upper or lower end position. The control unit and the corresponding set of pins can be released from the end position and moved up or down by manipulating an additional selection lever arranged outside the control unit. By depressing the selector lever, the locking plate is moved against the spring force. This allows the pins to be moved from their upper or lower end positions using the control means.
With this solution, the external control device is used to move the set of pins from a first end position (standby position) to a second end position (working position) and to lock the set of pins in these positions. This has the disadvantage that the selector lever must also be operated during the movement of the pins by means of the operating element. This prevents convenient one-handed operation. Furthermore, the operating element occupies a large space on the plug surface. This prevents the realization of a free design-oriented design and a compact design.
Chinese patent application CN105576408a1 discloses a travel conversion plug having a selection slider for selecting different standard plugs. The four actuating sliders are arranged oppositely. However, providing such a large number of actuating sliders results in one side of the housing being fully open, so that for example dust can enter. This is neither advantageous for the robustness of the adapter nor for electrical safety.
Us patent 7220139B 1 discloses a travel conversion plug having a slotted baffle in the housing wall. In the flap, an actuating slide can be moved. Depending on the position of the actuating slide in the shutter, various plugs are pushed out of the housing for use. This type of operation also has the disadvantage that one side of the housing must be relatively open. In addition, many users find it difficult to move the sliding door within the bezel.
Disclosure of Invention
It is an object of the present invention to provide an improved travel conversion plug which avoids the disadvantages of the prior art. Such travel conversion plugs should be inexpensive, reliable, easy to transport and operate, and provide a high level of electrical safety. It should also be compact and still be able to provide a connector that conforms to many standards.
The travel conversion plug of the present invention has a housing which may have different shapes. For example, a rectangular shape is generally suitable for transportation. However, the mechanical structure of the travel conversion plug is designed such that the housing shape can be selected largely freely. It is advantageous that the housing has at least one flat side, but the mechanical structure may also be adapted to curved housing surfaces. The housing may be one-piece or multi-piece. It has proven useful to design the housing in two parts, namely a lower part of the housing and an upper part of the housing. The two may be removably connected to each other, for example by mechanical means, or by a threaded connection.
The housing should have at least a plug receptacle. It is conveniently located at the top of the housing. The plug receptacle may have different shapes depending on the type of power plug (hereinafter simply referred to as plug) to be received. For example, if a Schuko plug is to be received, the plug receptacle will have a substantially cylindrical recess, and a connector receptacle which receives the connector pins of the Schuko plug. Other types of connectors do not require a notch or recess. It is desirable to provide a flat top of the housing on which several connector sockets are arranged. Typically, at least two connector receptacles should be provided, forming a pair of connector receptacles for holding a plug of a certain standard. It is useful to provide several pairs of connector sockets to accommodate several different standard plugs. If the plug also has a ground conductor and the plug socket is to provide the possibility of grounding, it is often necessary to provide a third connector socket or a third connector for each plug to be accommodated.
The travel conversion plug should also have at least one plug of a first standard and a second plug of a second standard. (such plugs are sometimes referred to as pin sets.) for example, the first standard plug may be a european EU plug and the second standard plug may be an american US plug. The plug may be bipolar, i.e. ungrounded, or tripolar, so that a ground electrode may be provided. Thus, the travel conversion plug is suitable for use in more than one country. It is advantageous, and often necessary, to use the first connector and the second connector alternatively.
The travel conversion plug may also include three or more plugs. Travel conversion plugs with three or four plugs have proven to be very useful. At least one plug, but typically all plugs, can be moved from a standby position to an active position; in the standby position, the plug is substantially located within the housing. In the use or operating position, the plug may be used wholly or at least partially outside the housing. When returned to the standby position, the plug can usually be moved completely back into the housing. It is desirable to move the plug back into the housing at least in a position that does not interfere with other plugs.
The invention relates to a connector having a housing and at least one first plug of a first standard. The first connector in turn has at least a first connector pin and a second connector pin. Thus, the connector may simply have the shape of a plug. The housing of which may be separate or integrated into the housing of another device. Accordingly, the plug may be located at the end of the cable or may extend directly from the housing of the electrical device. The plug connector can also be designed as a travel conversion plug, which then also has a plug receptacle.
The first connector pin is located on a first support element and the second connector pin is located on a second support element. The plug is movable between a standby position and an operative position, in which the plug is substantially located within the housing; in the operative position, the plug is accessible outside the housing.
The support element referred to in the present invention may take various forms. It has a basic mechanical function. The support element serves as a holder and an anchoring point for the at least one connector pin. Typically, the maximum extension of the support element is perpendicular to the connector pins. For example, the functional support element may have the shape of a crossbar from which the connector pins (e.g., ground pins) project vertically downward. The support elements in the form of cross bars are also referred to as support bars. The support member may also support two connector pins, for example, a live pole and a neutral pole (or a positive pole and a negative pole). The connector pins may also be arranged side by side and vertically downwards. It is useful if the geometry of the support element is more complex than a simple crossbar.
According to the invention, a connecting element is provided for the connector, by means of which the first and second support elements can be connected and can be moved together into an operating position. Correspondingly, the connecting element also has a standby position and a working position. The connecting element is in its operating position if it moves at least one support element and the associated connector pin into the operating position.
In the prior art, solutions are known in which all the joints complying with the respective standard (for example, the Schuko standard) are arranged on a single supporting element. If the joint pin is to be moved relative to the housing, one support element will move together with all the joint pins. This solution requires that one support element is provided for all joint pins. For standards comprising about three joint pins, for example the us standard, the support element must have a correspondingly complex shape. Such a support element must generally have at least one long support arm. This can result in poor transmission of power to the connector pins. Such support elements and/or their connector pins are also prone to tilting when moved into the operative position. Furthermore, such a carrier element requires a large amount of space and is difficult to accommodate satisfactorily in a compact housing.
In the present invention, it is possible to arrange the connector pins complying with a certain standard on different support elements. With the aid of the connecting elements, these supporting elements can be connected together and transferred together into the position of use. All connector pins complying with this standard can then be used together in the position of use.
The support element is moved in a first direction from a standby position to an operating position, generally parallel to the plane of symmetry of the housing. According to the invention, the connecting element itself can also be moved. Its movement perpendicular to the first direction moves the connecting element from the connected position to the disconnected position. In the connection position, the connection element connects the first support element and the second support element. On the other hand, in the disengaged position, this connection is cancelled.
The connecting element has proven to be useful when it can be moved together with the first and second support elements from the standby position into the operating position.
It has also proven useful to provide the connector with at least one first actuation slider (also referred to herein as slider button) by means of which the connecting element can be moved from the standby position to the working position. The actuation slider is purposefully mounted outside the housing, typically on a side wall of the housing. For this purpose, guide grooves may be provided in the side walls of the housing. The actuation slider may be firmly connected to the connecting element or may even form a one-piece component with the connecting element. In general, a mechanical connection is suitable, by means of which at least pressure can be applied to the connecting element, so that the connecting element can be moved from its standby position into its use position.
It is also advantageous to provide a second slider button which can be moved from the standby position to the operating position by means of the connecting element. The second slider button may be used as an alternative or in addition to the first slider button. The two sliders preferably act together on the connecting element; it is particularly useful if they are capable of exerting substantially the same force on the connecting element.
It has proven to be particularly useful for the two actuation sliders or slider buttons to be located at opposite positions on the housing. This makes the operation simple and even easy to apply force. This prevents the assembly from tilting when moving from the standby position to the operating position. Accordingly, it is generally desirable to also provide opposing guide slots on the housing. These can be arranged in a purposeful symmetrical manner with respect to a plane of symmetry of the housing, for example with respect to a mirror plane through the middle of the housing.
It is also desirable to provide the connector with a second plug of a second standard. The connector may usefully comprise at least a third joint pin arranged on the third support element and a fourth joint pin arranged on the fourth support element. Usefully, the connecting element can also connect the third support element and the fourth support element so that they can also be moved together into the operating position. It is also advantageous that the connecting element together with the third and the fourth support element can be moved from a standby position into a use position. Usually, the third and fourth load bearing elements are not moved to the working position, but instead to the use position, among other load bearing elements. This applies to all support elements of connectors that conform to different standards.
It is also useful to provide a third plug on the connector that conforms to a third standard. The third connector comprises at least one fifth joint pin arranged on a fifth support element. It is useful if the fifth support element can also be moved into the position of use by means of the connecting element. Thus, for the third connector, the connecting element is not used for connecting two support elements. The third plug should comprise only at least one, i.e. the fifth joint pin, and in particular it should comprise only at least one, i.e. the fifth, support element. For example, the third plug may be a plug without a ground terminal pin, wherein the live pole and the neutral pole are arranged adjacent to each other on a single support element. Accordingly, there is no need to connect with another support element, but the support element can still be moved to the position of use using the connecting element.
This means that the connecting element can effectively perform two functions: it can connect two support elements and thus a plurality of associated connector pins, which are to be moved together into the position of use. However, the connecting element may in fact also move a single support element into the position of use.

With regard to the connecting element, it should be noted that its horizontal movement for connecting or disconnecting the selected guide lug can be effected from the outside. A
However, the horizontal movement of the connecting element can advantageously be achieved only by selecting a button, so that no mechanical movement of the actuating slide is required. This is also generally undesirable, and therefore the guide grooves on the housing can be narrowed. There are many simple mechanical solutions to decouple the horizontal movement of the connecting
The mechanical system based on this concept will be explained in more detail in the following figures. The simple and precise movement of the connecting element allows a reliable connection of the two support elements. This is an important prerequisite for the mounting of a connector pin belonging to one standard on different support elements.
