[0002] Motor leads are a special type of cable. The leads are the various wire bundles branching off from the exposed ends of the stator windings, and are mainly conductors that provide power to the windings.
[0003] Since the exposed leads need to be impregnated and dried after being connected to the winding, the varnish layer on the outside of the leads may crack due to accidental pressure or pulling when heated, which will affect the insulation performance of the leads and, in severe cases, damage the winding.
[0004] In view of this, a claw-pole synchronous motor lead structure was designed to solve the above problems. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0031] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a claw-pole synchronous motor lead structure. Example 1
[0032] Combination Figures 1-4 As shown, the present invention provides a claw-pole synchronous motor lead wire structure, including a motor stator 100, a coil winding 200 disposed within the motor stator 100, and a quick-connect lead wire mechanism 300 disposed on the exposed end of the coil winding 200 extending to the outside of the motor stator 100. The quick-connect lead wire mechanism 300 is used to assemble on the exposed end of the coil winding 200 extending to the outside of the motor stator 100, and each lead wire on the exposed end of the coil winding 200 is evenly distributed within the quick-connect lead wire mechanism 300.
[0033] The quick-connect lead wire mechanism 300 includes an inner pad ring 380 and three sets of reinforcing frames 360, multiple cable routing slots 390 disposed in the inner pad ring 380, and an outer pad ring 320 disposed on the inner pad ring 380.
[0034] The outer ring 320 has an annular groove, and a first insulating pad 340, four second insulating pads 350, and an inner pad 310 disposed inside the first insulating pad 340 and the second insulating pads 350 are disposed in the annular groove. Two pads 330 are disposed between the inner pad 310 and the outer ring 320. A wire end anti-pull component 370 is disposed in the reinforcing frame 360.
[0035] Both the inner gasket 310 and the annular groove have evenly distributed arc-shaped insertion holes.
[0036] The coil windings installed in the stator of the claw pole synchronous motor have exposed ends that need to be led out to external leads. These leads need to be connected to external conductors, and the connection points need to be impregnated with varnish and dried. However, the parts that have been impregnated and dried in the traditional way may be damaged due to the heating operation and accidental pulling force, which may lead to the damage of the entire coil winding in severe cases.
[0037] This component mainly provides effective binding force for each lead on the coil winding. After the exposed part of the coil is clamped by the inner pad ring 380, each lead can be led out from multiple wire slots 390. Finally, the lead is pulled out from the soft rubber sleeve 372 and the clamp 371 until the lead passes through the part outside the clamp 371 and connects with the external wire. After the connection part is impregnated with varnish and effectively dried, the impregnated part is clamped by two locking screw caps 373 and locked towards the inside of the clamp 371. At this time, the lead can get effective heat dissipation protection in actual use, and at the same time, it can also provide anti-pulling protection. Example 2
[0038] Combination Figure 3 and Figure 4 As shown, based on Embodiment 1, one end of the reinforcing frame 360 is installed in the arc-shaped socket inside the annular groove, and the other end of the reinforcing frame 360 is installed in the arc-shaped socket inside the inner gasket 310.
[0039] There are six anti-pull wire end components 370.
[0040] Preferably, the number of anti-pulling wire end components 370 shown in the attached figures is the number of leads in the coil winding in real time. Depending on the number of leads in the coil winding of different motors, the number of wire slots 390 and anti-pulling wire end components 370 can be selectively increased.
[0041] The anti-pulling assembly 370 includes a clamp 371, a soft rubber sleeve 372 at the bottom of the clamp 371, and two locking screw caps 373 at the top of the clamp 371.
[0042] The clamp 371 consists of a T-shaped sliding sleeve coated with insulating varnish and an extended end tube, and the T-shaped sliding sleeve is inserted into the interior of the reinforcing frame 360;
[0043] The soft rubber sleeve 372 has a quarter-circular structure and is made of rubber material.
[0044] The locking screw cap 373 is made of thickened plastic.
[0045] Preferably, the soft rubber sleeve 372 is located in the gap between the outer gasket ring 320 and the inner gasket ring 380, and the soft rubber sleeve 372 is used to provide abrasion protection for the lead wire;
[0046] The extended rod end tube can be bent along the arc direction of the outer washer ring 320. After the two locking screw caps 373 fix the light-impregnated part, the slightly bent extended end tube can provide effective support for the external wire without interfering with the lead wire. Example 3
[0047] Combination Figures 1-3 As shown, in the above embodiments, both the first insulating pad 340 and the second insulating pad 350 are made of thickened silicone material;
[0048] The inner gasket 310, the outer gasket ring 320, and the gasket plate 330 are all made of stainless steel, and the surfaces of the inner gasket 310, the outer gasket ring 320, and the gasket plate 330 are coated with an insulating varnish layer.
[0049] Preferably, the first insulating pad 340 and the second insulating pad 350 can provide protection for the evenly distributed multiple reinforcing frames 360, wherein the width of the first insulating pad 340 and the second insulating pad 350 needs to be set according to the width of the exposed end of the coil winding 200, and the evenly distributed multiple sets of wire end anti-pull components 370 need to be located at the center of the exposed end to provide wear-free protection for the lead wire.
[0050] The working principle and usage process of this utility model: After the coil winding 200 is installed inside the motor stator 100, the exposed wire ends of the coil winding 200 need to be used as an external power supply wire harness.
[0051] After the inner gasket 310, the first insulating gasket 340, the second insulating gasket 350, and the outer gasket ring 320 are assembled on the exposed wire ends of the coil winding 200, the exposed leads of the coil winding 200 are then led outwards along the multiple wire routing slots 390. The leads are then fed into the soft rubber sleeve 372. As the leads are continuously delivered outwards, they eventually pass through the inside of the clamp 371. The leads are then passed through the part outside the clamp 371 for impregnation and drying. Then, the two locking caps 373 are pressed onto the outside of the impregnation layer of the leads. After the threaded sections of the two locking caps 373 are tightened into the threaded recesses at the top of the clamp 371, the pressed impregnation layer is fixed. At this time, the leads inside the clamp 371 are protected against pulling.
[0052] At the same time, the inner pad ring 380 provides constraint and protection for the exposed parts of the coil winding 200, so that each lead branching off from the coil winding 200 can be effectively clamped by multiple sets of wire end anti-pull components 370, thereby ensuring that the device can effectively improve the heat resistance and pressure protection of the leads.
