Description
[Technical field]
[0001] The utility model belongs to the technical field of refrigeration compressor motor stators, and in particular relates to a coil support for concentrated windings and a connection structure between the support and a coil lead-out line. [Background technology]
[0002] The stator is mainly composed of a stator core, a stator winding and a coil bracket. The inventor applied for a method for manufacturing a concentrated winding of a stator on March 3, 2023, with application number 2023102268841. Since a new coil bracket matching it had not been conceived when applying for the winding invention method, the final stator product manufactured by this method still used a conventional coil bracket, and could only be connected directly using complex and time-consuming manual leads. The connected wires are all located in a messy manner in the limited space of the coil bracket, and the wires need to be tied and fixed after wiring, without any wire processing. Therefore, the existing coil bracket is in urgent need of further improvement. [Contents of the utility model]
[0003] The technical problem to be solved by the utility model is to provide a coil support for concentrated winding and a connection structure between the coil lead wire and the coil lead wire, which can realize the orderly fixing, wire laying and connection of the coil lead wire.
[0004] To this end, the utility model provides the following technical solutions:
[0005] A coil support for concentrated windings is assembled in a nine-slot six-pole permanent magnet synchronous motor. The coil support comprises an annular side wall and arcuate side walls and tooth plates which are evenly arranged at intervals. The outer end of each tooth plate is connected to the bottom end of the annular side wall and the inner end thereof is connected to the bottom end of the corresponding arcuate side wall. The improvement is that it also comprises nine groups of wiring seats which are evenly arranged at intervals on the outer surface of the annular side wall. Each group of wiring seats consists of a lower step, a middle step and an upper step which are arranged in a ladder shape, and a lower vertical hole, a middle vertical hole and an upper vertical hole which are respectively opened on the top surfaces of the lower step, the middle step and the upper step. The lower vertical hole, the middle vertical hole and the upper vertical hole are all in communication with the annular side wall.
[0006] The lower vertical hole, the middle vertical hole and the upper vertical hole are communicated with each other through a long notch, a middle-long notch and a short notch which are arranged on the annular side wall and extend to the top thereof.
[0007] Since the coil is located at the tooth plate inside the coil bracket, the notch is set to eliminate the need to lead the coil lead wire through the annular side wall before it can be plugged into the terminal block. The long notch, the medium-long notch and the short opening are extended to the top of the annular side wall, which creates conditions for the needle winding machine to insert and pass the wire. The needle winding machine can selectively plug the lead wires of the different coils into the lower vertical hole of the lower step, the middle vertical hole of the middle step and the upper vertical hole of the upper step according to the needs of different coil lead wires, thereby pressing down the corresponding coil lead wires and selectively falling into the long notch, the medium-long notch and the short opening, which reduces manpower and increases efficiency and eliminates inefficient, error-prone and disordered manual wiring.

[0010] According to another aspect of the utility model, a connection structure between a coil support and a coil lead wire for a concentrated winding is provided, wherein there are 27 coil lead wires in total, the coil support is the aforementioned coil support, and the coil lead wires come from the first, second, and third coils wound layer by layer on each tooth piece in the coil support in sequence, and the improvement is that the coil lead wires on the adjacent order teeth pieces in every three teeth pieces in the circumferential reverse order are respectively plugged into the corresponding wiring holders in the adjacent order in the circumferential reverse order, wherein the first coil lead wire on the leading tooth piece, the second coil lead wire on the middle tooth piece, and the third coil lead wire on the rear tooth piece are connected in the form of hollow screws. The spiral column structures are respectively clamped in the corresponding lower vertical holes and connected together, and the lower vertical holes are adaptive cylindrical holes; the second coil lead-out wire on the leading tooth piece, the third coil lead-out wire on the middle tooth piece and the first coil lead-out wire on the rear tooth piece are respectively clamped in the corresponding middle vertical holes with a hollow spiral column structure, and are connected together, and the middle vertical holes are adaptive cylindrical holes; the third coil lead-out wire on the leading tooth piece, the first coil lead-out wire on the middle tooth piece and the second coil lead-out wire on the rear tooth piece are respectively clamped in the corresponding upper vertical holes with a hollow spiral column structure, and are connected together, and the upper vertical holes are adaptive cylindrical holes.
[0011] The first coil lead-out wire on the preceding tooth piece and the third coil lead-out wire on the following tooth piece are respectively clamped in the corresponding lower vertical holes, and then their respective lower wires are respectively dropped into concave intervals of equal height, and the wire ends of the lower wires are respectively connected to the wire ends of the second coil lead-out wire of the center tooth piece in the lower vertical hole; the second coil lead-out wire on the preceding tooth piece and the first coil lead-out wire on the following tooth piece are respectively clamped in the corresponding middle vertical holes, and then their respective middle wires are respectively dropped into concave intervals of equal height, and the wire ends of the middle wires are respectively connected to the wire ends of the third coil lead-out wire of the center tooth piece in the middle vertical hole; the third coil lead-out wire on the preceding tooth piece and the second coil lead-out wire on the following tooth piece are respectively clamped in the corresponding upper vertical holes, and then their respective upper wires are respectively dropped into open grooves, and the wire ends of the upper wires are respectively connected to the wire ends of the first coil lead-out wire of the center tooth piece in the upper vertical hole.
[0012] After adopting the above scheme, the coil lead wires on the adjacent tooth segments in every three tooth segments in reverse circumferential order are plugged in and fixed in an orderly manner, and the coil lead wires on the alternate tooth segments in the above tooth segments are laid in an orderly manner, and the coil lead wires on the adjacent tooth segments in every three tooth segments are connected together in an orderly manner, which embodies the advantage of neat wire laying and can also abandon the wire binding and fixing operation required for manual wiring.
[0013] The utility model has the following beneficial effects:
[0014] On the basis of the coil support structure of the prior art, when the wiring seats are arranged at intervals on the outer surface of the annular side wall, it is conducive to the orderly plugging and fixing of the coil lead wires. For the stator of the nine-slot six-pole permanent magnet synchronous motor, the lower, middle and upper vertical holes of the lower, middle and upper steps of the three adjacent groups of wiring seats in reverse circumferential order can be used for the corresponding coil lead wires on the adjacent order teeth of every three teeth in reverse circumferential order to be plugged in order according to the corresponding step positions, until the 9 lower vertical holes, 9 middle vertical holes and 9 upper vertical holes of the nine groups of wiring seats are plugged with 27 coil lead wires, and there is no omission, no error and easy to fix.
