[0075] The specific embodiments of the present invention are described in detail below in conjunction with the conversion socket of the second aspect of the present invention.

[0076] like Figures 5 and 6 A specific embodiment of the conversion socket shown includes an inner shell support, a covering portion 6 and a socket plate. At least two socket plates are provided, and the socket plates are positioned on the inner shell support. The covering portion 6 covers the periphery of the inner shell support and exposes the socket plate and the plug hole 21.

[0077] In this embodiment, when producing the conversion socket, the socket piece is positioned by the inner liner bracket, and then the outer periphery of the inner liner bracket is overmolded. The covering portion 6 can cover the intersection of the first bracket and the second bracket of the inner liner bracket, and cover multiple sides of the first bracket and the second bracket, so that the structure of the conversion socket after molding is more stable, and the PVC soft glue will not affect the socket piece inside the inner liner bracket, thereby improving the production quality of the conversion socket, making the glue injection more balanced, and shortening the molding cycle of the conversion socket.

[0078] The specific embodiments of the present invention are described in detail below in conjunction with the conversion socket production mold of the third aspect of the present invention.

[0079] like Figures 7 to 9 A specific implementation of a conversion socket production mold is shown. The conversion socket production mold 7 is used for the production of conversion sockets and includes a first mold 71 and a second mold 72 .

[0080] The first mold 71 is provided with an inner liner bracket positioning hole for positioning the inner liner bracket. After the inner liner bracket is positioned in the inner liner bracket positioning hole 73, a glue injection cavity is formed between the inner liner bracket and the inner liner bracket positioning hole. The first mold 71 is provided with a glue injection hole connected to the glue injection cavity. The second mold 72 is provided with a socket plate positioning hole 74 adapted to the socket plate. It should be noted that Figure 7 and Figure 8 It is a structural schematic diagram when the inner liner support has not been completely positioned in the inner liner support positioning hole 73.

[0081] In this embodiment, the first mold 71 positions the inner liner bracket, and the second mold 72 positions the two socket pieces extending from the inner liner bracket. When the first mold 71 and the second mold 72 are merged, a glue injection cavity for glue encapsulating the inner liner bracket will be formed. After the glue is injected from the glue injection hole, a covering portion can be formed on the periphery of the inner liner bracket.

[0082] The inner liner bracket itself occupies a certain space of the glue injection cavity, which can reduce the amount of glue injected, thereby speeding up the formation of the covering part and shortening the production cycle of the conversion socket.

[0083] If the inner liner support is not provided, the injected glue needs to fill more space, and the distribution of the glue often has an unbalanced problem. The inner liner support provided in this embodiment reduces the amount of injected glue, and the glue does not need to fill more space, making the distribution of the glue more balanced.

[0084] After the glue liquid injected into the glue injection cavity solidifies, it will not affect the socket piece no matter what the weather conditions are, thereby improving the production quality of the conversion socket.

[0085] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
