DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] In the description of the embodiments of the present application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0021] In the embodiments of the present application, unless otherwise specifically defined and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood in a broad sense, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the communication or interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0022] Please refer to Figure 1 The present application provides an embodiment: a conversion plug to prevent falling off, the conversion plug comprising a conversion part 1, a connection part 2 and a wire 3.

[0023] Please refer to Figure 2 The conversion part 1 has a conversion head 11, and a conversion tab 12 is arranged on the conversion head 11.

[0024] Please refer to Figure 3 A limiting slot 111 is arranged on the upper end surface of the conversion head 11, a tab hole 112 is arranged in the limiting slot 111, and positioning openings 113 are arranged on both sides of the limiting slot 111.

[0025] Please refer to Figure 4 The adapter part 2 has a plug 21 and a boss 22, the two ends of the plug 21 are provided with adapter openings 211, and the wire 3 is electrically connected with the plug 21. The boss 22 is fixed in the inside of the plug 21, and the bottom of the boss 22 extends to the outside of the plug 21. The boss 22 is a thin-walled structure with an opening at the top end and a hollow inside, and a circuit board 23 is arranged on the boss 22. The circuit board 23 is vertically arranged and is fixed on the boss 22 by screws. The circuit board 23 has a current conversion function and is provided with a control chip. The control chip is a prior art, and its circuit principle is not described here. The control chip can convert a 10A socket into a 16A socket that can adapt to 16A current, and can also control a 16A plug to pass only 10A current. The circuit board 23 is installed in the boss 22, and mounting plates 26 are arranged on both sides of the circuit board 23 on the boss 22. Each mounting plate 26 is connected with a pressing block 27 through a spring 25. The pressing block 27 away from the spring 25 end penetrates the boss 22 and the plug 21 from inside to outside in turn, and extends to the outside of the plug 21. One side of the circuit board 23 is provided with a micro switch 24. When two pressing blocks 27 are pressed by hands at the same time, the pressing block 27 extrudes the micro switch 24, sends an instruction to the micro switch 24, and makes the micro switch 24 disconnect the feedback signal to the circuit board 23 to control the electrical appliance to be turned off. Therefore, when the adapter part 2 is separated from the conversion part 1, it is not electrified, so as to avoid the risk of electrified plugging. The two pressing blocks 27 are symmetrical to the two sides of the boss 22, and the two pressing blocks 27 pass through the two adapter openings 211 respectively. The two pressing blocks 27 can move in the two adapter openings 211 respectively. The boss 22 is provided with a clamping block 28 at each end. The two clamping blocks 28 are clamped in the two positioning openings 113 respectively. By clamping the two clamping blocks 28 in the two positioning openings 113 respectively, and making the two clamping blocks 28 be triangular pyramids, the conversion part 1 and the adapter part 2 can be completely fixed. During use, the plug 21 will not fall off from the conversion head 11.

[0026] Please refer to Figure 5 An adapter tab 29 is arranged on one end of the boss 22 close to the conversion head 11, and the adapter tab 29 is inserted into the tab hole 112.

[0027] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
