Description

A kind of motor outlet structure

Technical field:

The utility model relates to a kind of motor outlet structure.

Background technology:

Traditional motor outlet structure adopts parts such as insulation board, outlet sheath, packing ring usually, and there is following shortcoming in this structure: 1) complex structure, and parts are many, and it is also many that machine adds part, and working (machining) efficiency is low, and cost is high; 2) the outlet sheath is thinner, and the insulation property in end cap are poor, have hidden danger; 3) binding post and terminal adopt screw, nut connection reliability poor; 4) whole outlet box volume is bigger; 5) outlet direction is single.

Summary of the invention:

The purpose of the utility model provides a kind of motor outlet structure, and is simple in structure, easy for assembly, disassembly and maintenance, reduced the application of part, improved working (machining) efficiency and fail safe, reduced product cost.

The purpose of the utility model is achieved through following technical proposals.

A kind of motor outlet structure comprises shell, rotor assembly, stator core, stator winding and outlet box, and stator core is nested in outside the rotor assembly; Stator winding is wound on the stator core, and stator core and shell are installed and connected, and outlet box is installed on the shell; It also comprises collets, and collets are installed on the shell and place in the outlet box, offer some through holes on the collets; Through hole is provided with binding post; Collets wrap binding post, and the winding leads of drawing from stator winding connects binding post one end, and outside lead connects the binding post other end.

Above-mentioned described shell comprises inner sleeve, outer sleeve, front end housing and rear end cap, and outer sleeve is nested in outside the inner sleeve, and front end housing and rear end cap are installed in the inner sleeve two ends, and outlet box is installed on the rear end cap.

Above-mentioned described binding post comprises public spigot and female spigot, and public spigot connects outside lead, the sub-connection winding lead-in wire of female spigot, and public spigot embeds in female spigot.

Above-mentioned described outlet box comprises box body and lid, and box body is installed on the rear end cap, and lid is installed on the box body.

On the above-mentioned described lid locker is installed, is offered wire hole in the middle of the locker, outside lead is drawn through wire hole.

The utility model compared with prior art has following effect: 1) collets of the utility model have replaced an original insulation board, 3 outlet sheaths, 3 packing rings, have reduced the application of part, have improved working (machining) efficiency, have reduced product cost; 2) collets are bigger than the insulation distance of outlet sheath in end cap, increased creepage distance, improved electrical safety performance; 3) binding post comprises public spigot and female spigot, and public spigot connects outside lead, the sub-connection winding lead-in wire of female spigot; Public spigot embeds in female spigot, and public spigot and female spigot filial generation are for original binding post, and public female terminal is a standard component; Low price is safeguarded easily, and wiring firmly adds part for machine; Working (machining) efficiency is low, and cost is high; 4) public spigot embeds female spigot at the collets back panel wiring, has reduced the volume of outlet box, can avoid the interference of motor when car load assembles; 5) can be towards a plurality of direction outlets.
