[0002] The power converter socket is used to convert one type of socket into another or multiple types of sockets, including converting one type of plug into a multi-hole socket or a single-hole socket, to meet the needs of a large number of electrical devices or to enable the installed plug board to meet the access of other types of plugs, so as to meet the needs of the increasing number of electrical devices in life. For example, the existing electric RV uses a battery pack to power the entire RV, but after the RV is driven to the rest area, various electrical appliances will be used, such as an induction cooker for cooking. Since the battery pack powers the RV with direct current, and the conventional induction cooker and other electrical appliances require alternating current to start, a power converter socket is needed.

[0003] The existing power converter sockets are generally electrically connected to the RV battery pack. When not in use, due to the lack of a self-protection structure, the socket may leak electricity. In addition, the power converter socket lacks shell protection, and water or dust may fall into the socket and cause damage to the socket. Therefore, the utility model proposes a self-protection travel power converter socket to solve the above problems. Utility Model Content

[0030] In this embodiment, the power converter socket includes an input socket, an output socket 14, a protection mechanism 15 and a power adapter. The input socket is used to receive an input power plug. In this embodiment, the input socket is externally connected to a motorhome battery pack, and the output socket 14 is used to output power. The input power, i.e., the DC current of the motorhome battery pack, is converted by the power adapter to convert the DC power of the battery pack into AC power and sent to the output end, and the protection mechanism 15 can control the on and off of the output socket 14; specifically: when the input socket is connected to the motorhome battery pack, the DC power of the battery pack is converted into AC power by the power adapter, and is transformed into AC power suitable for ordinary household appliances by a transformer and then input into the output socket 14. At this time, since the protection mechanism 15 can control the on and off of the output socket 14, the output socket 14 has no electricity, and when the external plug is inserted into the output socket 14, the pressure cap 152 is pressed down by the plug to contact the pressure cap 152, and the pressure cap 152 slides downward in the through hole 151 to contact the conductive column 153, driving The conductive post 153 moves downward to connect the terminal post 154. After the conductive post 153 and the terminal post 154 are connected, a path is formed, so that the converted AC power is connected to the output end socket 14. At this time, the external plug is inserted into the output end socket 14 to realize power-on use. A return torsion spring is provided at the bottom of the conductive post 153. When the conductive post 153 is not subjected to vertical force, the return torsion spring can drive the conductive post 153 to move upward away from the terminal post 154 to disconnect the two. After the output end socket 14 is powered on, the indicator light will light up, and the indicator light Lighting up is also an indication that the circuit is fully connected, which can determine whether the circuit is fully connected; when the power converter socket is not in use, the protective cover 22 is covered on the outside of the upper cover 12 to achieve dust and water resistance for the output socket 14. When in use, the protective cover 22 can be pulled out. Due to the effect of the sealing ring, the protective cover 22 can tightly cover the upper cover 12, and the sealing ring also has the effect of dust and water resistance; the output socket 14 is a five-core structure in this embodiment, and of course it can be determined to be a two-core, three-core, five-core or other multi-core structure according to actual usage.

[0031] For further information, see Figure 1 and Figure 4 A plurality of positioning holes 11 are formed on the housing 1 .

[0032] For further information, see Figure 1 and Figure 4 A positioning column 17 is fixedly provided on one side of the positioning hole 11 .

[0033] In this embodiment, the role of the plurality of positioning holes 11 is to facilitate the fixed installation of the power converter socket on the RV. The positioning holes 11 and the positioning columns 17 cooperate to achieve hole spacing positioning, which plays a role in positioning and preventing mistakes in the installation of the power converter socket.

[0034] For further information, see Figure 2and Figure 3 An indicator light window 16 is provided on the top surface of the upper cover 12 , and an indicator light is provided inside the indicator light window 16 .

[0035] In this embodiment, when the internal circuit of the power converter socket is fully connected, the indicator light will be lit. The lighting of the indicator light is also an indication that the circuit is fully connected, and it can be judged whether the circuit is fully connected.

[0036] Furthermore, it also includes an input socket for receiving an input power plug.

[0037] In this implementation manner, the input end socket is used to receive an input power plug. In this embodiment, the input end socket is externally connected to a RV battery pack.

[0038] The working principle and use process of the utility model are as follows: when the input socket is connected to the RV battery pack, the DC power of the battery pack is converted into AC power through the power adapter, and is transformed into AC power suitable for ordinary household appliances by the transformer and then input into the output socket 14. At this time, since the protection mechanism 15 can control the on and off of the output socket 14, the output socket 14 has no electricity. When the external plug is inserted into the output socket 14, the pressure cap 152 is pressed down by the plug to contact the pressure cap 152. The pressure cap 152 slides downward in the through hole 151 to contact the conductive column 153, driving the conductive column 153 to move down and connect the terminal 154. After the conductive column 153 is connected with the terminal 154, a passage is formed, so that the converted AC power is connected to the output socket 14. At this time, the external plug is inserted into the output socket 14 to realize power-on and use.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
