The present invention is related to a standard socket adaptor, in particular, to a multi-standard socket adaptor capable of providing sockets adapted to various standards of socket heads around the globe including the ones for the countries of German and France, which also conforms to the voltage standards of 125-volt and 250-volt socket specifications, achieving greater practical uses and applications thereof.
In view of common universal socket adapts provided for appliances around the globe, the problem associated with the incorrect matches among different terminals and standards often occurs; in other words, a number socket heads of certain standards cannot be fitted to the socket adaptor.
As the technology of electronic devices improves rapidly, most of the electronic devices are designed to consumed less energy; therefore, the wall plugs designed for traditional usages are not sufficient in meeting the current uses. There is a need to improve the electrically connections of electric sockets among various different standards and to cope for multiple plug-ins.
However, unsafe usage of traditional socket adaptors occurs often. One must consider the quality of the socket, the terminals to be matched or to cooperate with the socket heads for plug-ins and the tightness of the plug-ins as well as the capacity of loading on the electrically charged surface area in order to ensure the safety of the usage. As the material costs continues to rise high with uncertainties, it is necessary to design a socket adaptor taking into account of the importance of energy saving concerns as well as the quality and efficiency of the usage in order to facilitate the use of the socket adaptors in various fields and among different connections thereto.
It is clear that an electrical socket adaptor providing for both the plug-ins of the sockets of 125 volt and 250 volt is currently unavailable in the market; therefore, having an electrical connection conforming to the standards of different countries and their electrical specifications as well as electrical applications at the same time can be troublesome, which cannot be achieved easily while introduces greater burdens to the users.
In view of the abovementioned drawbacks of the prior socket adaptors, with years of research and development in the same industry and experience, the inventor designs and provides a multi-standard socket adaptor capable of adapting to socket heads of international standards of various countries and providing sockets for the inputs and outputs of 125-volt and 250-volt.
The primary objective of the present invention is to: integrate electric sockets conforming to both 125-volt and 250-volt socket specifications into one single socket adaptor. The socket adaptor is provided with a voltage indication lamp to prevent the plugging in of 125-volt socket head to the socket for 250-volt such that users can plug in different socket heads into the socket adaptor according to standards and voltages of different countries in order to achieve the safety and practical usages of the socket adaptor.
To achieve the objective recited above, the present invention provides a multi-standard socket adaptor, comprising at least one socket interface and a housing attached to said socket interface, and an internal of said housing comprises a first terminal set and a second terminal set conforming to a 125-volt and a 250-volt socket specification respectively; wherein said socket adaptor comprises a first socket set and a second socket set corresponding to said first terminal set and said second terminal set respectively as well as conforming to said 125-volt socket specification and said 250-volt socket specification respectively. The first socket set and the second socket set respectively comprise a first live line of a L terminal, a first naught line of a N terminal and a first earth line of an E terminal, a second live line of a L terminal, a second naught line of a N terminal and a second earth line of an E terminal. Furthermore, the housing further comprises a first connecting port electrically connected to the first terminal set and conforming to the 125-volt socket specification and a second connecting port electrically connected to the second terminal set and conforming to either the 125-volt or the 250-volt socket specification. In addition, the second terminal set is electrically connected to a joining portion.
With the abovementioned structures and configurations, the socket adaptor of the present invention provides a design for both the plug-in of the input and output voltages of 125-volt and 250-volt such that users can correctly and safely plug the socket heads of 125-volt and 250-volt into the corresponding sockets and such that the practical and safe usages of socket adaptors conforming to international standards of various countries including the ones for German and France can be achieved.
at least one first terminal set 12 conforming to a 125-volt socket specification, provided in an internal of said housing 11; wherein said first terminal set 12 is defined with a first live line of a L terminal 121, a first naught line of a N terminal 122 and a first earth line of an E terminal 120;
at least one first socket set 13 conforming to a 125-volt socket specification, cooperating with said first terminal set 12;
at least one second terminal set 14 conforming to a 250-volt socket specification, provided in an internal of said housing 11; wherein said second terminal set 14 is defined with a second live line of a L terminal 141, a second naught line of a N terminal 142 and a second earth line of an E terminal 143;
at least one second socket set 15 conforming to a 250-volt socket specification, cooperating with said second terminal set 14.
According to the abovementioned structure and configuration, wherein the housing 11 comprises a first connecting port 123 electrically connected to said first terminal set 12 and conforming to said 125-volt socket specification as well as a second connecting port 145 electrically connected to said second terminal set 14 and conforming to said 250-volt socket specification. The second connecting port 140 is also electrically connected to a power supply line 144 conforming to the 250-volt socket specification. Furthermore, aid second terminal set 14 extends outward to penetrate through said socket interface 10 to form a grounding portion 17 conforming to the standards for grounding in German and France.
In view of the structure and assembled design recited above, the following further describes the operation and cooperation of the present invention in practice. As shown in
German and France. As the user plug in the socket heads corresponding to the specification of German and France, proper grounding can be achieved in practice. Furthermore, the socket adaptor 1 of the present invention is capable of cooperating with the first connecting port 123 for operation thereof. In addition, the socket adaptor 1 of the present invention can also cooperate with an extension for operation thereof by attaching the corresponding portion 20 provided on one side of the housing 11 to the second connecting port 145 in order to achieve a repeated configuration and implementation for operation thereof in practice. Also, a enforced grounding portion 18 is provide on an external wall of the socket adaptor 1, an a joining rod 19 having a collapsed form and provided on the enforced grounding portion 18 can be further electrically connected to the second earth line of the E terminal. Therefore, regardless of the directions of the plugin of the socket heads, proper groundings can be achieved via the enforced grounding portion 18 and the joining rod 19 such that the electrical connections adapted to the socket heads of the standards of German and France can be achieved.
