[0019] In practical applications, the aforementioned shell 1 can be made of glass fiber reinforced nylon material, thereby significantly reducing the overall weight of the plastic shell.

[0020] The insulator 4 mentioned above can be made of glass fiber reinforced nylon.

[0021] Glass fiber reinforced nylon is a material whose mechanical properties are enhanced by adding glass fibers to nylon. Nylon itself has excellent mechanical properties, heat resistance, wear resistance, self-lubrication, and certain flame retardancy, but it is highly hygroscopic and has poor dimensional stability, which limits its application to some extent. By adding glass fibers, these shortcomings can be effectively improved, especially long glass fiber reinforced nylon (LGFR-PA66), whose mechanical properties are significantly better than short glass fiber reinforced nylon (SGFR-PA66), and its molding and processing performance is also better. The shell is produced by injection molding, which has high production efficiency and stability.

[0022] Specifically, the pins and sockets of the aforementioned contact can be made of brass wire, the inner sleeve of the aforementioned contact can be made of leaded brass wire, and the spring wire and claws of the aforementioned contact can be made of beryllium bronze.

[0023] Brass is an important copper-based alloy, mainly composed of copper and zinc. It has good electrical and thermal conductivity, elasticity and mechanical properties, and is easy to form, weld, cut and polish. It has a wide range of applications, especially in electrical engineering, mechanical manufacturing and piping engineering.

[0024] Leaded brass is a brass alloy composed of copper, zinc and a small amount of lead; it is widely used in many fields due to its excellent mechanical properties, wear resistance, corrosion resistance and electrical conductivity.

[0025] Beryllium bronze, especially the QBe2 type, is a beryllium bronze alloy containing a small amount of nickel. Its main chemical composition includes copper (Cu) as the main component, with the balance being nickel (Ni) at 1-2% and beryllium (Be) at 0.5-1.2%. This alloy can have its mechanical and physical properties significantly improved through specific heat treatment processes (such as quenching and aging).

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
