Description
Technical field
The present invention relates to plug production technical field, particularly relate to a kind of plug and production technology thereof.
Background technology
Existing plug mostly includes plug core and is wrapped in the housing outside plug core, plug core and housing
Assembling mode is the outside that housing is directly injection-moulded in plug core, makes plug core form integrative-structure with housing.
But owing to plug core is directly to be molded upper shell, injection moulding process can heat plug core, in plug core
Parts of plastics is easily melted with metal portion connection plastics, causes parts of plastics bad with metal part contact,
Affecting product quality, it addition, the housing adopting this method the plug of processing is thicker, the plastics of use are more,
Plug overall weight after injection is heavier, and internal material is uneven, and overall structure is unstable.
Summary of the invention
It is an object of the invention to: provide a kind of plug, it can reduce the injected plastics material that plug uses, and reduces
The weight of plug, reduces material cost, and can carry out plug core certain heat insulation, it is ensured that plug core is moulded
Material part is good with metal part contact, it is ensured that the internal material of the plug after injection is uniform, and overall structure is steady
Fixed.
Further object is that: provide the production method of a kind of plug, it is in the inside of plug core
One encapsulation inner shell is first set, the most again at plug core and the surface injection casing of encapsulation inner shell, the most right
Plug core is thermally insulated, it is ensured that the parts of plastics within plug core is not easily separate with metal part, separately
On the one hand decrease the injected plastics material of shell, save cost.
For reaching above-mentioned purpose, the present invention by the following technical solutions:
