Problems solved by technology
In these existing technologies, the waterproof effect cannot be really achieved. If the waterproof cover is not covered, or the contact surface between the plug and the socket is not tight, the sealing ring cannot play a waterproof role, which will cause the internal parts of the socket to be wet. , it is easy to cause a short circuit and cause a fire or electric shock

Embodiment Construction
[0020] like Figure 1-5 As shown in the figure, a power expansion board that seeps water and will not short-circuit includes an upper case 1, a lower case 2, and a socket seat 3, and the upper case 1 is provided with at least one set of socket seats 3 integrally formed by injection molding. unit, the upper housing 1 of this embodiment is provided with a set of jack sockets for live wire jacks and jack sockets for neutral wire jacks that are integrally molded with the two-insert socket unit 12 and two sets of live wire jacks A three-prong socket unit 13 composed of a socket socket, a socket socket of a neutral wire socket and a socket socket of a ground wire socket. The lower casing 2 is provided with a terminal block 5 which is matched with each unit jack seat of the upper casing. The terminal block 5 is integrally injection-molded with the lower casing 2, and an electrode conductive sheet 6 is arranged in the groove of the terminal block. The conductive sheet is fixed in the...

The invention provides a power supply expansion plate being free of short circuit in the case of water seepage. The power supply expansion plate comprises an upper shell body, a lower shell body and jack seats. The upper shell body is provided with at least a set of jack seat unit which is in injection moulding integration with the upper shell body. The lower shell body is provided with a connection seat which is in cooperation with an upper shell body jack seat. A connection base groove is provided with an electrode conducting strip which is electrically connected with an external lead. A jack seat lower end face and a connection seat upper end face clamp an elastic contact piece closely. Space is provided between the elastic contact piece and the electrode conducting strip. A jack seat jack sidewall close to an elastic contact piece upper end face is provided with a scupper. The scupper is led out through a flexible pipe to connect with a scupper of an upper shell sidewall. A jack top sidewall is provided with a projection piece. A junction of the upper shell body and the lower shell body is provided with a seal washer. The invention has the characteristics of simple structure, low manufacture cost, anti-creep, anti-seepage and good safety performance.
Description
technical field [0001] The invention relates to a power expansion board, in particular to a power expansion board which cannot be short-circuited by water seepage. Background technique [0002] The power expansion board is an electrical product used in daily life to achieve electrical connection through the insertion of an external plug. During use, people often encounter a watery environment, or accidentally splash water on the power expansion board, causing accidents. happened. Therefore, technicians have developed power expansion boards with waterproof functions. These waterproof power expansion boards are equipped with waterproof covers outside the sockets to prevent water from penetrating into the socket holes. Some power expansion boards have sealing rings outside the socket holes, and the plugs are inserted into the sockets When in the hole, the plug and the socket are sealed. In these existing technologies, the waterproof effect cannot be really achieved. If the wa...
