Description
Technical Field
[0001] The utility model relates to an electrical connection converter, in particular to a plug converter. Background Art
[0002] In the prior art, a plug adapter is an important tool to solve the problem of inconsistent socket standards in different countries. These traditional adapters usually adopt a fixed-shaped blade and socket design, making them only adaptable to specific types of sockets. This design limits the versatility of the adapter and may require carrying multiple different adapters to meet various socket requirements. Although some universal converters attempt to provide more compatibility, they are usually large in volume due to their complex structure, which is inconvenient for travelers who need to carry multiple socket conversion tools.
[0003] In addition, the universal socket converters in the prior art often lack flexibility and scalability in design. These converters are usually designed as a fixed structure with an unchangeable shape, making it difficult to adapt to changes in the shapes and specifications of different sockets. Even if some converters provide adjustable functions, their designs often result in operational inconvenience or problems in adapting to different sockets. Therefore, the converters in the prior art face challenges such as excessive size, single function, and insufficient compatibility.

Detailed implementation manners
[0035] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments described below and the features in the embodiments can be combined arbitrarily with each other.
[0036] Many different implementation manners or examples are provided below to implement the structure of the present utility model.
[0037] See Figures 1 - 12, A plug converter according to an embodiment of the present utility model includes: a conversion wire 1, which is composed of a conductive wire. Two ends of the conversion wire 1 are respectively connected with a single-sided conductive insert 2 and a single-sided universal socket 3. The single-sided conductive insert 2 can be composed of a single-sided conductive insert of a specific regional standard specification plug, and can be directly inserted into a single hole of the specified regional standard mains socket to achieve electrical connection with the mains power supply. For example, Figure 1 in the figure, the single-sided conductive insert 2 is adopted in two ways and inserted into two TYPE B jacks 201 of the mains socket 31 respectively, then power can be obtained for use. For details, see Figure 2 As shown, the single-sided universal socket 3 includes a universal socket hole 8 and conductive clips 9 arranged inside the universal socket hole 8. The single-sided universal socket 3 can be adaptively inserted into plug conductive inserts of different shapes. The plug conductive insert of an electrical appliance such as a mobile phone charger is inserted into the universal socket hole and clamped and kept in contact by the conductive clips 9 to achieve electrical connection. Because it is like a clip inside and the external hole can contain plug inserts of different shapes from various countries, it can be adapted to plug inserts 32 of electrical appliances with different standard specifications or shapes from various countries. For example, Figure 3 As shown; it further includes a conversion base 4. One end of the conversion base 4 is provided with a single-sided female socket 6 for the single-sided conductive insert 2 to be inserted for conductive connection. The other end is provided with a single-sided conversion insert 5, which has a different specification and shape from the single-sided conductive insert 2; when the jack of the mains socket is adapted to the shape of the single-sided conductive insert 2 (such as both being circular), the user can obtain power by inserting the two single-sided conductive inserts 2 into the positive and negative jacks of the mains socket respectively; when the jack of the mains socket is not adapted to the shape of the single-sided conductive insert 2, the user can insert the single-sided conductive insert 2 into the single-sided female socket 6 for series connection, and insert the single-sided conversion insert 5 into the jack of the mains socket. Thus, the compatibility between the conductive insert of the plug converter and the jack of the mains socket is extended. And because the conductive inserts (single-sided conductive insert 2, single-sided conversion insert 5) are of single-sided structure, the shape formed between multiple jacks of the mains socket does not affect the insertion of the single-sided conductive insert 2 or the single-sided conversion insert 5. For example, Figure 3 shown by the TYPE A insert 101 and TYPE C jack 202 in the figure.
[0038] Considering that both ends of the conversion cable 1 are a single-sided universal socket 3 and a single-sided conductive plug 2, the conversion socket 4 is a single-sided conversion plug 5 and a single-sided female socket 6, and both the charger and the mains socket have positive and negative poles. Therefore, in this embodiment, there are multiple conversion cables 1 and conversion sockets 4 (each can be 2, and considering the ground wire, it can also be set to 3 each, and the conversion socket 4 can also be set more). By means of the multiple conversion cables 1 and conversion sockets 4, the single-sided conductive plug 2 can be inserted into the mains socket directly or in a series connection mode through the conversion socket 4. The single-sided universal socket 3 is used to adapt to the electrical appliance plug, so as to realize the connection and power supply of the electrical appliance. Thus, when charging is needed, the electrical appliance plug brought by the user is plugged into at least 2 single-sided universal sockets 3, and power can be obtained by plugging at least 2 single-sided conductive plugs 2 into the mains socket 31. Or after connecting the single-sided conductive plug 2 to the single-sided female socket 6 on the conversion socket 4, plugging the single-sided conversion plug 5 into the mains socket can also obtain power. The embodiment of the present utility model ingeniously adopts the way of breaking up the whole into parts, splitting the conductive plug, universal socket, and conversion plug from the traditional fixed type of 2 or 3 in a group into a single-sided structure, so that the single-sided structure can better adapt to the electrical appliance plug and the mains socket, and thus is not restricted by the distance, shape, and relative position between various jacks. By setting the conversion socket 4, the single-sided conversion plug 5 and the single-sided conductive plug 2 are plugs with different specifications and shapes, further expanding the specifications and shapes of the plugs, so that the range of plugs adapting to the mains socket can be enlarged. For users, they do not need to carry a large-sized adapter, but only need to carry two flexible conversion cables and the conversion socket and other structures thereon, and can conveniently and safely use the sockets of various countries to obtain power, which is convenient to carry and has better compatibility.
[0039] In some embodiments of the present utility model, the conversion socket 4 and the conversion cable 1 are independently arranged; in other embodiments, as Figure 1 shown, the conversion socket 4 is connected to the conversion cable 1 through a cord 7. The conversion socket 4 is not easy to lose and does not need to be stored separately, which is convenient for users to carry. There can be multiple conversion sockets 4 to adapt to the socket shapes or sizes in different regions. The multiple conversion sockets 4 can be connected to the conversion cable 1 through a cord 7, or can be used as independent accessories. Among them, there may be no electrical connection between the cord 7 and the conversion cable 1, only a fixed connection, so as to avoid short circuit caused by the conductor contact between multiple conversion sockets 4. Or the conversion socket 4 can be made into an independent accessory. For example, the single-sided conversion plug 5 of the conversion socket 4 can be TYPE A-TYPE P to adapt to the jacks of the mains sockets 31 of various national standards. As shown in Figure 4, where 100A-100P are the sockets 100 of different standards of various countries.
[0040] Specifically refer to Figure 4As shown, since the jack shapes of mains power sockets in various countries are diverse, including but not limited to the 100A-100P specification, in some embodiments of the present utility model, the shapes of the single-sided conductive inserts 2 and the single-sided conversion inserts 5 include at least three shapes. Among them, the shape of the single-sided conductive insert 2 is one kind, and the shapes of the single-sided conversion inserts 5 are the remaining two or more kinds. The insert shapes include blade-shaped, cylindrical or square-columnar. In this embodiment, there are 2 single-sided conductive inserts 2, specifically, they can be Figure 5 the blade-shaped inserts 10 in Figure 5 There are 4 single-sided conversion inserts 5, two of which are
[0041] In some embodiments of the present utility model, as Figures 5 - 6 shown, the single-sided conductive insert 2, or the single-sided universal socket 3, or the single-sided conversion insert 5 is provided with an insulating seat body 14 wrapped around it to protect the electrical safety and facilitate plugging and unplugging. Among them, as Figure 7 shown, one side surface of the single-sided conductive insert 2 or the single-sided conversion insert 5 has a magnetic or tenon mechanism, so that the seat bodies of at least two single-sided conductive inserts 2 or single-sided conversion inserts 5 can be combined to form a combined plug 20 like a standard type, and two conversion lines 1 can be operated simultaneously like a complete plug. In this way, for users, it can better conform to the previous socket usage habits.
[0042] Specifically, refer to Figure 8As shown, in some embodiments of the present utility model, the single-sided conductive insert 2 or / and the single-sided conversion insert 5 are arranged as telescopic inserts 15 relative to their seat bodies, and the seat bodies form telescopic seat bodies 21, so that the single-sided conductive insert 2 or the single-sided conversion insert 5 can be telescopic or folded relative to their respective seat bodies to achieve opening or storage. By adopting such a telescopic or folding method, the inserts can be stored usually and the required specific insert can be pushed out for use when needed. The telescopic inserts on the seat body 14 are one or more. When multiple telescopic inserts are provided, the insert shapes of the telescopic inserts on the seat body 14 are different. According to the hole shapes on the mains socket, the corresponding inserts can be selectively pushed out to improve the adaptability.
[0043] See specifically Figure 10 As shown, in some embodiments of the present utility model, the single-sided female socket 6 has holes, and the holes are universal socket holes 8, forming a universal conversion seat 22, which can be adapted to various shapes of inserts. In this way, when connected in series, different insert shapes can be applied. For the manufacturing factory, the inventory of different conversion seats 4 can be reduced, so the cost can be reduced, and it is also easier for users to plug and unplug.
[0044] See specifically Figure 12 As shown, in some embodiments of the present utility model, a control box 33 is further arranged between multiple conversion lines 1. A lighting group 34 or / and a fuse 35 or / and a switch 36 are arranged in the control box 33 for different functions or protection purposes. When the lighting group 34 is on, it means that the insert is inserted into the correct socket hole, and the fuse 35 can prevent the electrical appliance from causing an instantaneous large current, and the switch 36 can turn off the electrical appliance at the rear end through additional control. In addition, a USB power output socket 37 is also equipped on the control box 33, which can provide an additional 5V power supply, so that various 3C devices such as mobile phones and tablets can conveniently draw power for use.
[0045] See specifically Figure 11As shown, in some embodiments of the present utility model, when in use, two conversion wires 1 can be used as a group, respectively connected to the positive electrode and the negative electrode, or three can be used as a group, respectively connected to the positive electrode, the negative electrode and the ground wire 13, and different colors can be used to distinguish different conversion wires. For example, the third ground wire 13 can be green, the positive electrode can be red, and the negative electrode can be black and other colors for distinction. Therefore, in one embodiment, when facing the TYPE G jack 203, power can be obtained by inserting through the conversion base 4 with a corresponding shape. At the end of the electrical appliance plug 32, the TYPE J blade 102 can also be inserted into the single-sided universal socket 3. And when a ground wire 13 is needed, the same third conversion wire can be used as the ground wire 13 to obtain an electrical connection to the ground terminal. Since the seat bodies 14 on each socket and each blade can be designed to be very thin, narrow and small, it is possible to avoid squeezing together with the seat bodies 14 of other single blades or single sockets.
[0046] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present utility model.
