Abstract
The invention relates to a plastic package stator, consisting of plastic package material and a plastic sealing down link limit spigot positioning part, a gasket is arranged between a head cover surface and a wound stator winding, a through hole and a gasket support pillar are arranged on the gasket, the electric security performance between a head cover and a stator winding can be effectively guaranteed, meanwhile the plastic packaged stator has smooth external surface and beautiful appearance.
Description
Technical field: the present invention relates to a kind of small and special electric machine, particularly relate to a kind of plastic packaging stator that uses in the small and special electric machine.
Technical background; When producing small and special electric machine, generally all adopt stator to carry out plastic packaging, its objective is and guarantee that stator has the good insulation performance performance, traditional stator plastic packaging method as shown in Figure 1, generally be with the coiling after stator module be that benchmark is placed on the mandrel of plastic sealed mould with the stator inner hole, mandrel is provided with positioning spigot, with the downstream position of restriction stator.With the plastic package die matched moulds, make the upper and lower mould closure of plastic sealed mould then, the patrix of plastic sealed mould is provided with some backstays, and when plastic sealed mould was closed, backstay compressed stator, with the upward position of fixed stator.Though this technology is easy, the mold position bar is provided with more, and processing loaded down with trivial details, maximum defective is can stay many backstays hole at the good plastic packaging stator outer surface of plastic packaging, influences the attractive in appearance of whole work-piece.
Summary of the invention; Purpose of the present invention will provide a kind of plastic packaging stator exactly, and the plastic packaging stator that adopts method of the present invention to produce can overcome the existing defective of above old-fashioned production method effectively, improves productivity effect, the surface of the work smooth and beautiful appearance of producing simultaneously.The object of the present invention is achieved like this, a kind of plastic packaging stator is by end cap, capsulation material, and plastic packaging is formed with descending spacing seam positioning element, it is characterized in that: with the wound stator winding is that benchmark is placed on the mandrel of plastic sealed mould with the stator inner hole, and positioning spigot is set on the mandrel; Fixing specific packing ring of design that passes through of upward position, packing ring and stator insulation skeleton are compressed, when plastic sealed mould was closed, the small end lid plane that the clamping plane of patrix and packing ring are placed above compressed, and the wound stator winding is in a fixed position in the plastic package die of closure.The plastic packaging stator surface of the work smooth and beautiful appearance that adopts the present invention to produce can reach end cap and stator winding again simultaneously and obtain an electrical safety distance, guarantees the electrical safety performance of product, has improved productivity ratio.
Description of drawings:
Fig. 1 is the structural representation of old-fashioned plastic packaging stator;
Fig. 2 is the structural representation of plastic packaging stator of the present invention;
Fig. 3 is the structural representation of packing ring;
1. capsulation material, 2. plastic packaging is with descending spacing seam location, 3. packing ring wall thickness, 4. stator insulation skeleton, 5. packing ring, 6. wound stator winding, 7. end cap plane, 8. packing ring support column, 9. through hole.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, a kind of plastic packaging stator is by end cap, and capsulation material 1, plastic packaging are located 2 parts with descending spacing seam and formed, and it is characterized in that: is that benchmark is placed on the mandrel of plastic sealed mould with wound stator winding 6 with the stator inner hole, and positioning spigot is set on the mandrel; Fixing specific packing ring 5 of design that passes through of upward position, packing ring 5 and stator insulation skeleton 4 are compressed, when plastic sealed mould was closed, the small end lid plane 7 that the clamping plane of patrix and packing ring are placed above compressed, and wound stator winding 6 is in a fixed position in the plastic package die of closure.During concrete enforcement, the fixed-site of stator winding one of them direction in plastic package die, adopt supporting bead, the position of the push rod that can remove mould internal cause fixed stator and form, the effect of supporting bead, be the effect (support stator and end cap) of playing upper and lower support, the packing ring wall thickness has been guaranteed the electrical safety performance between end cap and stator winding; In order to make packing ring, end cap, stator in the technical process of plastic packaging, thermoset plastics is successfully flowed, on the wall thickness of packing ring, be provided with large through-hole.Groove position between lead to the hole site and stator winding is in same upright position, make thermoset plastics by the groove between winding to the upper reaches, through hole by the packing ring wall thickness, packing ring, end cap, stator available heat are fixed on one, through hole is sealed by the engineering plastics thermosetting behind plastic packaging, can guarantee the electrical safety performance between end cap and stator winding equally.
