Safety adapter structure improvement

The present invention provides an improved structural structure of a safety adapter, especially a safety adapter having multiple clamping functions and safety protection functions, and is suitable for multi-country transfer.

According to the sockets in the world, the electrical connection holes are different. Therefore, in order to facilitate the people who go abroad to use the electrical appliances of the original countries in the world, the manufacturers can manufacture the same rules for the US, Europe and the UK. Plug with sockets such as Australian regulations. However, the structure of such a universal plug is quite complicated, and a large number of conductive sheets are required in the space inside the casing, and a large number of adjusting elements for moving the above-mentioned conductive sheets are provided. In use, the user can adjust the adjusting component connected to the conductive sheet according to the type of the electrical connection hole of the socket, so that the conductive piece corresponding to the electrical connection hole can be protruded or turned out on the housing, and the other remaining The conductive sheet is housed in a space inside the housing or an outer surface of the housing.

In addition, some parts of the universal adapter are similar, and the housing has a large number of openings for plugging the plugs of various national specifications, and then the universal adapter is inserted into the socket of a certain country to Convert to country outlet specifications.

Recently, adapters have been introduced from many countries to many countries. It is common to replace plugs or sockets of different specifications with replacement methods, and the replacement methods are not only elastic fixing, movable switch clamping or sliding fixing. Regardless of the replacement method, when the plug and the socket are disassembled and separated, the conductive sheets at the joint are exposed, so that the conductive sheet is easily worn, damp, and poorly contacted, especially when the conductive sheet at the plug end is exposed, the risk of accidental electric shock is more likely. And the frequent disassembly action is also likely to cause poor connection between the plug and the socket. Therefore, if only relying on a single fixing method, it is very easy to cause the adapter to be unusable for a long time.

Therefore, how to solve the above problems and deficiencies in the past, that is, the applicants of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the applicants of this new type have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed this multi-fixing function. And a new type of patent for the safety protection function and for the improvement of the safety adapter structure of multi-country transfer.

The main purpose of the present invention is to provide the conductive sheets (the first and second electrode portions) in the plug body and the universal socket, and to hide and avoid the exposure even when disassembling and separating.

Another main purpose of the present invention is to use the first and second electrode slots of the L shape, and the first and second electrode plugs that can be combined with each other, and after the plug body and the universal socket are combined, the card is clamped by the center. , and increase the fixing strength and stability of the plug body and the universal socket.

In order to achieve the above object, the structure of the present invention comprises: a plug body for supplying power to the mains power source, and at least one active slot group is defined on a side of the plug body facing away from the mains connection end, the active slot group includes a grounding a slot, a first electrode slot formed on one side of the ground slot and having an L shape, and a second electrode slot formed on the side of the first electrode slot and having an L shape, and the plug The main body correspondingly includes a universal socket for transferring plug components of various specifications, the universal socket is formed with at least four socket portions, and the universal socket defines an electrical connection away from a side of the connecting end of the plug component. An active plug-in group of the active slot group, the active plug-in group includes a grounding plug corresponding to the grounding slot, and a first one disposed on a side of the grounding plug and corresponding to the first electrode slot An electrode plug, and a second electrode plug disposed on a side of the first electrode plug and corresponding to the second electrode slot, and having a plurality of bending electrodes respectively formed on the first electrode plug and the second electrode plug end Electrode hook The system is respectively engaged in the first electrode slot and the second electrode slot; the present invention utilizes the assembly and disassembly action of the plug body and the universal socket to freely replace the commercial connection end of the corresponding specification, so that in addition to the universal socket It can be applied to plug components of various specifications, and can also be applied to various specifications of commercial power supply, and the connection between the plug body and the universal socket can be utilized in addition to the active insertion of the movable docking group and the side edge of the active slot group. The electrode hook portions at the ends of the first and second electrode plugs are electrically connected to the L-shaped first and second electrode sockets to complete the corresponding locking action, and the combination of the plug body and the universal socket is strengthened from the central portion. The strength and stability are protected from the first and second conductive portions in the bare plug body or the universal socket, thereby increasing the safety of the assembly operation.

With the above technology, the conductive sheet existing in the conventional adapter can be exposed to the outside and is easy to cause grinding. Loss, moisture or electric shock, and the combination of the plug and the socket are too monotonous, and it is difficult to overcome the problem of long-term wear and tear, and achieve the practical progress of the above advantages.
