Description

A converter with multi-standard plugs

Technical field:

The utility model relates to the field of power converters integrating plugs and sockets, in particular to a converter with multi-standard plugs.

Background technique:

With the increasingly close international exchanges, the intercommunication and use of electronic products in various countries is becoming more and more extensive, such as directly purchasing foreign electronic products and returning them to China, or making tourists or business personnel carry mobile phones, digital cameras, laptops and other electronic products with them. product. The plugs of electronic products are all fixed in a standard form, and the socket standards of various countries are mostly different from each other. The types, forms and sizes of plugs and sockets are quite different. Convert the plug to solve this problem.

The multi-country conversion plug means that a product has multi-standard plugs at the same time, so it can adapt to plugs of different specifications in multiple countries, but because multiple plugs are on one product, if more than two plugs are conducting at the same time Once one of the plugs is inserted into the socket, the other exposed plug will also be charged at the same time, which will cause the risk of electric shock. Therefore, the patents stated in patent ZL02815377.4 and EP1393417B1 install four plugs in the body and Set three slides on the sliding track of the plug. When any plug is pulled down and exposed on the surface of the body, it will occupy the sliding space of the slide and fix the three slides, so the other three plugs cannot be pushed down. The surface of the plug, so that the two plugs will not be pulled out at the same time, causing the risk of electric shock. Another Chinese patent ZL200620015634.5 describes that the plug is set at both ends, pushed left and right, and the other plug is rotated from the bottom. The appeal of the patent is to allow only a single plug to be pushed out of the product, and other plugs will be restricted and cannot be pushed out to ensure safety in use. Chinese patent ZL2007201724580 uses a rotating column, and there are four sliding grooves on the four sides of the rotating column, allowing Any plug is pushed out along the sliding groove. When one plug is pushed out, the corresponding positions of the other plugs and the sliding groove have changed and cannot be pushed out again. Therefore, the effect that a single plug can be pushed out and other plugs cannot be pushed out can also be realized.

These patents, because the four plugs are far away from each other, in order to ensure the safety of use, they can only be restricted by the internal structure, so the structural design is relatively complicated, and the manufacturing cost is relatively high. If the structure is defective, it is possible for a single plug to be released. The function fails, causing the user to have a superficial danger of electric shock.

The utility model proposes a converter with multi-standard plugs. In addition to solving the problem of poor applicability of unified electronic products for plugging various standard sockets in different countries or regions, the structure of single plug push-out is omitted in structure, but It can also ensure that one plug is not inserted into the socket and the other plug is still protruding outside, causing the risk of electric shock.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figure 1-11B, a converter with multi-standard plugs has a combination of upper socket 1 and lower socket 2. Through this combination, various plugs can pass through this product, and it can be used in European, British, and European standards. It is used in different socket systems such as Australian and American regulations. In the European standard socket system, the upper socket 1 can be used alone. In the British, American and Australian socket systems, the upper socket 1 is inserted into the lower socket 2, and the lower The plug of the socket 2, the upper socket 1 is inserted into the lower socket 2, a European plug 11 is formed under the upper socket 1, and a European plug 11 for the upper socket 1 is formed above the lower socket 2 Inserted European gauge jack 25; the lower socket 2 is provided with two sets of movable plugs of different specifications, and the movable plugs are pushed out of the lower socket 2 or retracted into the lower socket 2 through the push buttons 223 and 214. A group of movable plugs of different specifications are respectively a three-pin plug 21 of British style and a two-pin plug 22 shared by American style and Australian style.

Specifically, as shown in Figures 3 and 4, an upper socket 12 is formed on the surface of the upper socket 1, and a dustproof part is arranged inside the upper socket 1, including a dustproof cover 13 covering the upper socket 12, and the center of the dustproof cover 13 is There is a horizontal round hole, a spring 15 is placed, the dust cover 13 is installed on the bracket 14, a protrusion 141 and a blocking piece 142 are formed on the bracket 14, and the spring 15 is against the blocking piece 142 of the bracket 14, so The above-mentioned protrusion 141 is above the track on which the dust cover 13 slides. When the plug of the electric appliance is inserted into the upper jack 12, the plug of the electric appliance pushes the dust cover 13 to enter the interior of the upper socket 1, the dust cover 13 moves backward, the spring 15 is compressed under the thrust of the dust cover 13, and the protrusion 141 limits the position of the dust-proof cover 13. After the plug of the electrical appliance is pulled out, the dust-proof cover 13 resets under the elastic force of the spring 15. The detailed function of the protrusion 141 is described as follows. When the user uses his own plug to insert This product, but not inserting both pins of the plug into the socket hole 12, but only inserting one pin into the socket hole 12 of the product, and one pin is exposed to the outside, at this time, the dust cover 13 has only one side When the force is applied, it will tilt to the side where the force is applied. After the dust cover 141 is tilted, it will be blocked by the protrusion 141, so the dust cover 13 will no longer slide, the socket hole 12 cannot be opened, and the user's plug cannot be inserted into the socket hole 12. , thereby reminding the user of this improper use, and at the same time preventing the user from the danger of electric shock.

The shaft hole 2211 on the conductive joint 2210 is provided with a thread to match the thread of the cylindrical shaft 2221, so that the pin 222 rotates along the shaft hole 2211. The British three-pin plug 21 and the American-Australian shared two-pin plug 22 pass through the circuit board 23 respectively, so that their pins are electrically connected to the circuit board 2 .

The upper socket 1 is provided with an AC-to-DC power supply module 16, at least one USB charging port 161 and a conductive socket flower 162, which can be connected to the electronic product through a USB data cable to realize charging of the electronic product. At least one piezoresistor or at least one negative ion generator is connected in series between the fire and neutral wires on the power module 16 to protect the circuit from overvoltage damage. A group of circuits for charging the battery is added in the power module 16, and a battery is placed under the power module. The European plug 11 is composed of a pin 112 and a pin seat 113, and the pin 112 is provided with a perforation 111, and an electronic wire or a fuse or a temperature switch or a thermal fuse is welded in the perforation 111; the pin 112 is installed on the pin seat 113 Above, there is a pin seat lock hole 1131 on the pin seat 113, and the pin seat 113 is located on the upper socket 1. When a short circuit or leakage occurs, the electronic wire or fuse or temperature switch or thermal fuse is disconnected to protect electrical appliances.

When using, choose the required plug specifications according to your needs, there are European plugs, American plugs, British plugs and Australian plugs. The following is the use of various specifications of plugs:

European-style plug: the plug 11 of the upper socket 1 is a European-style specification, and the upper socket 1 is used alone, and the plug 11 is inserted into the socket to be connected with the mains.
