Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the utility model or equivalent substitutions of parts of technical features without departing from the spirit of the utility model are intended to be covered by the scope of the claims of the utility model.

As shown in fig. 1 to 5, a wire clamp for a plastic package motor comprises an upper wire clamp 1 and a lower wire clamp 2, wherein the outer sides of a first plane 4 and a second plane 5 of a buckling surface of the upper wire clamp 1 and the outer sides of the second plane 2, which are far away from the buckling surface, are respectively provided with a fixing wing for preventing the wire clamp from turning outwards or shifting after injection molding along the horizontal direction. Go up fastener 1 and lower fastener 2 and go up the symmetry respectively and be equipped with wire groove 6, the lead-out wire of stator solenoid passes wire groove 6, will go up lower fastener 1 with lower fastener 2 carries out the lock in appropriate position, will detain go up fastener 1 with in injection mold is put into to lower fastener 2's stator, the one end that has the fixed wing is detained on injection mold through the fixed wing, moulds plastics, has effectually prevented that prior art's fastener after high pressure is moulded plastics, has the problem of turning on one's side easily or shifting. The fixed wings are arranged, so that the resistance of relative movement of the plastic package material and the wire clamp during injection molding is increased, the problem that the wire clamp turns over or shifts during high-pressure injection molding is well solved, and remarkable effects are achieved through multiple production practices.

Further, the fixed wing comprises two upper wings 12 and two lower wings 22, the two upper wings 12 are vertically arranged on the front side of the upper wire clamp 1 away from the first plane 4 of the buckling surface and are vertically arranged with the axial direction of the wire outlet hole 3, and the two upper wings 12 are located in the same plane; the two lower wings 22 are arranged on the front side of the lower wire clamp 2, which is far away from the second plane 5 of the buckling surface, and are symmetrically arranged with the two upper wings 12; the two upper wings 12 and the two lower wings 22 are integrally formed with the upper clip 1 and the lower clip 2, respectively. One type of retainer wing is proposed herein, in which two upper wings 12 and two lower wings 22 are fastened to an injection mold to increase the resistance of the wire guide clip to relative movement with respect to the injection molding material, thereby preventing the wire guide clip from being displaced or turned over due to impact during high-pressure injection molding.
