Description

Technical Field

[0001] This utility model relates to the field of adapter plug technology, and in particular to an adapter plug. Background Technology

[0002] In existing technologies, traditional power sockets or plugs typically employ a split structure. For example, prior art 202321498462 discloses a three-prong power cord, which separates multiple female plugs via wiring. However, this design has the following drawbacks:

[0003] 1. Insufficient strength: Since the female plug is connected through the circuit, it is easily damaged or broken by pulling or other external forces, which affects its service life.

[0004] 2. Portability: The split design makes the power cord easy to get tangled, making it inconvenient to carry and use.

[0005] 3. Safety issues: Separate circuits may pose safety hazards in high temperature or high humidity environments, increasing the risk of short circuits or leakage. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a converter plug that has higher structural strength, higher safety and is easy to carry.

[0007] To solve the above-mentioned technical problems, this utility model discloses a converter plug, including a male plug, three female plugs and a housing; the male plug is installed at the head of the housing and is connected to the mains power; the three female plugs are all installed at the tail of the housing and are arranged adjacent to each other, and the female plugs are used to connect electrical equipment to achieve power supply;

[0008] The male plug has three independent connecting wires led out from each of its three phase prongs, for a total of nine connecting wires; for each female plug, three connecting wires of different phases are connected to the corresponding phase prong of the female plug.

[0009] All connecting wires are installed inside the housing.

[0010] As an alternative implementation, the three female plugs are arranged side by side.

[0011] As another alternative implementation, the housing is injection molded from PVC.

[0012] As another optional implementation, the surface of the housing is also provided with anti-slip texture.

[0013] As another optional implementation, the male plug is a C20 male plug.

[0014] As another alternative implementation, the female plug includes two plum blossom-shaped female plugs and one triangular-shaped female plug.

[0015] As another optional implementation, the plum blossom tail female plug is a C5 plum blossom tail, and the triangular tail female plug is a C13 triangular tail.

[0016] As another alternative implementation, the housing is made of environmentally friendly flame-retardant material.

[0017] As another alternative implementation, the connecting wires between the male plug and the three female plugs are wrapped with insulating material and fixed inside the housing.

[0018] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0019] The adapter plug of this utility model has an integrated design, which converts one male plug into three female plugs through a single housing, rather than a separate structure, thus having higher structural strength; the connection wires between the male and female plugs run inside the housing, which is safer than exposed wiring; the structure is compact and easy to carry; the female plugs are located at the tail of the housing, which makes it easy to plug in multiple electrical devices at the same time, avoiding the problems of insufficient power sockets or messy cables in traditional power outlets.
