Description
Technical field
The present invention is with to separate hornwork relevant, particularly about a kind of RCA fixture construction of separating hornwork.
Background technology
Separate the feedback device of hornwork as back coupling revolution position; Mainly be to utilize the excitation variable winding of stator to excite signal through one; And produce the magnetic field interlinkage with the rotor that rotates, again by the induction coil induced field of stator with the output sensor signal, and the formation of coil generally is to accomplish through the groove tooth that winds the line on stator on the stator; Yet; Because the coil of institute's winding completion still still needs and the outside constitutes status of electrically connecting, therefore, coil must come to constitute the state that is electrically connected with the outside after winding is accomplished through a winding member.
And existing technology contents in order to status of electrically connecting between winding coil and outside; Particularly, it is like Fig. 1 and shown in Figure 2, and its connecting piece 1 is made up of a fixed pin portion 2 and 3 in a movable pin portion; Wherein, This fixed pin portion 2 is fixedly arranged in the space between the adjacent bidentate utmost point 5 of stator 4, and the line end of stator coil 6 is electrically connected with this fixed pin portion 2, again through can with this fixed pin portion 2 bonding state that this activity pin portion 3 that combine is electrically connected with outside formation of pegging graft.
Though above-mentioned concrete prior art can be accomplished the status of electrically connecting between stator coil and outside, yet because it is this fixed pin portion 2 to be positioned be arranged in the confined space between the adjacent bidentate utmost point 5, therefore; When the stator tooth number of poles more for a long time, promptly make this fixed pin portion 2 can't be set in the narrow space between the adjacent bidentate utmost point 5, moreover; Because stator coil 6 is when winding is accomplished, therefore its line end is not positioned on the same position, with this fixed pin portion 2; Promptly must the line end of coil be connected in this fixed pin portion 2 via extending lead-in wire 7, that is to say that extending lead-in wire 7 must be via whole sequence of threads; Being fixed in stator extends on distolateral again and is connected with this fixed pin portion 2; Thus, will cause the tediously long process requirement of whole sequence of threads, and the high heat that is produced during motor running; To make that also putting in order the insulation adhesion that is used for fixing extension lead-in wire 7 in the sequence of threads produces situation about coming off under temperature action; Make the former extension lead-in wire of being fixed 7 lose the location and produce skew, cause extending coming off, rubbing of lead-in wire 7, cause damage.
