In order to make the objects, the technical solutions and the advantages of the present invention more comprehensible, the present invention will be further described in detail by the accompanying drawings. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides an adapter plug which is integrally injection-molded and has a simple structure and can realize conversion connection of different standard plugs.

As shown in FIG. 1, the adapter plug includes an intermediate injection molded part 120, a metal post 110, and an adapter pin 130. The metal post 110 and the transfer pin 130 are disposed in the intermediate injection molded part 120. The two ends of the intermediate injection molded part are a male plug end 122 and a male plug end 121, respectively, and the male plug end 121 is used for plugging with a plug that needs to be transferred to other standards, and the male plug end 122 is used for plugging. It is connected to a structure such as a socket, and the male plug end 122 and the male plug end 121 are made of a conductive metal, such as copper. The metal post 110 is located at the male plug end 122, the metal post 110 is exposed from the male plug end 122, and the transfer pin 130 is located at the male plug end 121, which is exposed from the male plug end 121. In addition, the number of the metal posts 110 and the transfer pins 130 are equal, and the layout of the transfer pins 110 and the transfer pins 130 are different, so that it is possible to adapt to the conversion between plugs of a plurality of different standards. The metal post 110 is electrically connected to the transfer pin 130 through the inside of the intermediate injection molded part 120 in one-to-one correspondence. In view of the prior art, the technical problem to be solved by the present invention is to provide an adapter plug which is simple in structure, low in cost, and capable of realizing conversion between plugs of different standards, and is not only used for LED lamps but also for displays, etc. Exported products have a wide range of applications.

In order to provide a protective effect on the transfer pin 130, the transfer pin 130 is prevented from being bent and broken. In a preferred embodiment, a female protective cover structure is disposed in the transfer male insertion end 121. Taking the structure shown in FIG. 1 as an example, in this embodiment, the plastic insertion slot 1211 is disposed in the adapter male insertion end 121, and the plastic protection groove 1211 is recessed from one end of the intermediate injection molded component to the inner portion thereof. The transfer pin 130 is located inside the plastic protection groove 1211 and is exposed from the innermost portion of the plastic protection groove 1211. Thus, the transfer pin 130 is generally not subjected to the impact or bending force of the external device and is not easily damaged. further. Since the male plug-in terminal 121 needs to be docked with other plugs, the plastic protection slot 1211 can also be used to guide the docking process in order to facilitate accurate docking and docking. As shown in Figure 1, each of the transfer pins 130 is located at the axis of a cylindrical cavity, i.e., the transfer pin 130 is at the axial center of the cylindrical cavity, along the cylindrical cavity. Axial extension, guidance, positioning, can also play a better role in protection.
