Thus, the inner mold 400 can prop against the positioning hole 320 to fix the inner frame 300 more stably, and particularly, the positioning convex ring 330 is not easy to loose between the inner frame 300 and the positioning hole 320 of the inner frame 300 when designed.

In the process of manufacturing, firstly, the wire core of the electric wire 500 is stripped to expose the copper wire by an insulating sheath with a proper length, so that the exposed copper wire can well penetrate into the crimping holes at the rear side of the terminal post 200 of the inner frame 300, and the terminal post 200 and the copper wire are effectively connected by being provided with corresponding cutters for crimping through a terminal crimping machine. And then the connected inner frame 300 and the electric wire 500 are provided with corresponding moulds by an injection molding machine to carry out plastic injection molding, and the injection molding part is the inner mould 400, so that the plug has better toughness. Finally, the inner mold 400 is provided with a corresponding mold by an injection molding machine, and a plastic injection molding outer mold is used as the socket body 100.

In some embodiments, referring to fig. 2, the positioning bead 330 includes a front bead 331 facing the front side and a rear bead 332 facing the rear side. The front convex ring 331 plays a role of extending the positioning hole 320 without changing the thickness of the inner frame 300, so that the inner frame 300 is more stable when the inner mold 400 is propped against the positioning hole 320. The rear flange 332 may also support the inner mold 400 in addition to extending the positioning hole 320, so that the inner frame 300 and the positioning hole 320 are less likely to be loosened.

In some embodiments, the lengths of the front convex ring 331 and the rear convex ring 332 are a, and the value of a is 1-2mm, so that the structural strength of the front convex ring 331 and the rear convex ring 332 is ensured.

In some embodiments, the inner frame 300 is provided with a terminal mounting collar 340, and the terminal post 200 is inserted into the terminal mounting collar 340, so that the terminal post 200 is more stable in the inner frame 300, and also plays a role in stabilizing the inner frame 300.

In some embodiments, referring to fig. 3 and 4, the inner frame 300 is in a shape of a "convex" shape, and the upper side, the left side and the right side of the inner frame 300 are provided with inner frame protrusions 310, and the inner frame protrusions 310 are provided with rounded portions, so that the structure is more compact and stable.

In some embodiments and referring to fig. 3, a positioning recess 350 is provided on the underside of the inner frame 300, so that the inner frame 300 is fixed before injection molding.

In some embodiments, ground terminal 201 is located on the upper side of inner housing 300, live terminal 202 is located on the left side of inner housing 300, and neutral terminal 203 is located on the right side of inner housing 300.
