This ensures reliability of a connection between the feeding part 33 and the support rib 2, and ensures that the support rib 2 effectively supports the feeding part 33.
  • a first hot-melt pole 27 is disposed on the support rib 2.
  • the feeding part 33 is provided with a first location hole 331 through which the first hot-melt pole 27 passes.
  • the support rib 2 and the feeding part 33 are connected through hot melting and fitting between the first hot-melt pole 27 and the first location hole 331.
  • the first location hole 331 on the feeding part 33 may be pre-sleeved on the first hot-melt pole 27, to pre-locate the feeding part 33. Then, a position that is on the first hot-melt pole 27 and that passes through the first location hole 331 may be hot melt by using a mold, to implement hot-melt fastening between the feeding part 33 and the support rib 2. In this way, the first location hole 331 fits the first hot-melt pole 27 to ensure position accuracy of fitting between the feeding part 33 and the support rib 2.
  • each support rib 2 may be integrally formed when the mechanical part 1 is produced, to ensure reliability of an entire structure.
  • a width size of the gap H formed between the support ribs 2 may be greater than or equal to a thickness size of the antenna body 3.
  • the antenna body 3 can be easily clamped into the gap H, to facilitate mounting of the antenna body 3, and ensure reliability of clamping the antenna body 3.
  • a material of the support rib 2 may be but is not limited to plastic, glass, ceramic, or the like.
  • the plastic is preferably used.
  • the plastic can facilitate processing and production, and has low costs.
  • the plastic helps implement a light weight of the electronic device.
