[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] The AC stator core insulating sleeve of this utility model, such as Figures 1 to 7 As shown, the device includes an insulating sleeve body 1. A positioning block 2 is fixedly installed on the outer side wall of the insulating sleeve body 1. The side wall of the positioning block 2 is provided with multiple snap-fit ​​grooves 3. The outer side wall of each snap-fit ​​groove 3 is provided with a coil inlet 4 extending into the inner cavity of the snap-fit ​​groove 3. A conductive snap-fit ​​block 5 is provided in each snap-fit ​​groove 3. The snap-fit ​​block 5 is inserted into the snap-fit ​​groove 3. The lower end of each snap-fit ​​block 5 is provided with two clips 6. There is a wire insertion gap between the two clips 6. The two clips 6 are inverted V-shaped. A paint-breaking blade 61 is provided on the clamping surface of the clips 6. Adjacent snap-fit ​​blocks 5 are connected by a conductive connecting piece 7.

[0024] The charging ignition coil and charging lighting coil are both wound on the winding teeth of the AC stator core. The charging ignition coil and charging lighting coil use enameled wire, and the insulating varnish on the enameled wire is easily worn away, posing a high risk of leakage. Therefore, an insulating layer needs to be set on the AC stator core to isolate the enameled wire from the AC stator core and prevent leakage from the coil to the AC stator core. In this invention, the insulating sleeve body 1 serves as the insulating layer that isolates the enameled wire from the AC stator core. The insulating sleeve body 1 is an insulating shell, and its shape and size are adapted to the shape and size of the AC stator core. The ends of the AC stator core can be inserted into the insulating sleeve body 1. By inserting both ends of the AC stator core into the insulating sleeve body 1, and the ports of the insulating sleeve body 1 abutting at both ends, an insulating layer covering the surface of the AC stator core is obtained.

[0025] Positioning block 2 is an insulating block used to position the charging lighting coil end 10 and the snap-fit ​​block 5. The structure of positioning block 2 is as follows: Figure 1 and Figure 2 As shown, the side wall of the positioning block 2 is provided with multiple snap-fit ​​slots 3. The snap-fit ​​slots 3 are rectangular slots, and there can be three, four, etc., depending on the requirements. The coil inlet 4 connects the inner and outer spaces of the snap-fit ​​slots 3, so that the charging lighting coil end 10 can extend into the interior of the snap-fit ​​slot 3 through the coil inlet 4.

[0026] The snap-fit ​​block 5 is made of conductive material, specifically common metals such as copper or iron. The shape and size of the snap-fit ​​block 5 body are adapted to the inner cavity of the snap-fit ​​groove 3, ensuring that the snap-fit ​​block 5 and the snap-fit ​​groove 3 can have an interference fit. That is, after the snap-fit ​​block 5 is inserted into the snap-fit ​​groove 3, the side wall of the snap-fit ​​groove 3 is squeezed and generates elastic deformation and elastic force. This elastic force can press the snap-fit ​​block 5 tightly, ensuring the stability of the snap-fit ​​block 5.

[0027] The clamping pieces 6 are used for positioning the charging and lighting coil end 10, and the distance between the two clamping pieces 6 gradually decreases from bottom to top in the utility model. When the clamping pieces 6 are not deformed, the distance between the lower ends of the two clamping pieces 6 is greater than the diameter of the charging and lighting coil end 10, and the distance between the upper ends of the two clamping pieces is less than the diameter of the charging and lighting coil end 10. When the clamping block 5 is inserted into the clamping groove 3, the clamping pieces 6 are driven to move downward, and the charging and lighting coil end 10 can easily pass through the distance between the lower ends of the two clamping pieces 6 and enter between the two clamping pieces 6. As the clamping pieces 6 continue to move downward, the charging and lighting coil end 10 gradually contacts the clamping pieces 6 and is gradually clamped by the clamping pieces 6. The clamping pieces 6 have a certain elasticity and can clamp the charging and lighting coil end 10 by using the elasticity thereof. The side edge of the clamping piece 6 towards the wire insertion distance is provided with a paint breaking blade 61. Specifically, as shown in Figure 7 The side edge of the clamping piece 6 can be provided as an inclined surface, and the edge of the inclined surface is used as the sharp paint breaking blade 61. When the clamping pieces 6 clamp the charging and lighting coil end 10, the paint breaking blade 61 breaks the insulating paint film on the surface of the charging and lighting coil end 10, so that the clamping pieces 6 and the charging and lighting coil end 10 can be conductively connected.

[0028] The connecting piece 7 connects the clamping blocks 5 into one, so that the clamping blocks 5 are conductively connected to each other, and then the charging and lighting coil ends 10 can be conductively connected. The clamping blocks 5 and the connecting piece 7 are connected into one, and all the clamping blocks 5 can be inserted into different clamping grooves 3 at one time, so that the operation is convenient.

[0029] In the utility model, after the charging and lighting coil ends 10 are inserted into the clamping grooves 3 through the coil inlets 4, the clamping blocks 5 are inserted into the clamping grooves 3, the clamping pieces 6 move downward after entering the clamping grooves 3, and the charging and lighting coil ends 10 enter between the two clamping pieces 6 and contact the clamping pieces 6. In order to ensure that the clamping pieces 6 clamp the charging and lighting coil end 10, the lower part of the inner wall of the clamping groove 3 in contact with the two clamping pieces 6 can be provided as an inclined surface, the distance between the two inclined surfaces gradually decreases from top to bottom, and the lower end of the clamping piece 6 is deformed by the extrusion of the inclined surface, so as to clamp the charging and lighting coil end 10.

[0030] It can be seen that the utility model can complete the connection between the charging and lighting coil and the clamping block 5 without adopting the tin-bushing welding process, the operation is more convenient and fast, the production cost is reduced, and the production efficiency is improved.

[0031] In the utility model, the top of the clamping block 5 is provided with a U-shaped wire connecting piece 8, the wire connecting piece 8 can be integrally formed with the clamping block 5, and the wire connecting piece 8 is used for being connected with an external wire, so that the clamping block 5 can be conductively connected with external power supply equipment and the like, and then the charging and lighting coil is conductively connected with the external equipment.

[0032] The utility model discloses, positioning block 2 and insulating sleeve body 1 integrated moulding, specifically, insulating sleeve body 1 is plastic cover, adopts moulding process to be batched with the insulating sleeve body 1 of having positioning block 2.

[0033] The coil inlet 4 can be a circular hole, and as a preferred embodiment, the coil inlet 4 is a strip-shaped notch extending from the mouth of the clamping groove 3 to the middle of the clamping groove 3, and the width of the strip-shaped notch is slightly larger than the diameter of the electric lighting coil end 10. After the electric lighting coil end 10 is inserted into the clamping groove 3 through the coil inlet 4, the electric lighting coil end 10 is slid downward to the bottom of the strip-shaped notch, and at this time, the electric lighting coil end 10 is located in the middle of the clamping groove 3. During the downward movement of the clamping piece 6, after the electric lighting coil end 10 contacts the clamping piece 6, the electric lighting coil end 10 is subjected to the clamping force of the clamping piece 6 and the downward force, and the downward force bends the electric lighting coil end 10 downward, as shown in FIG. 6, so that the electric lighting coil end 10 is not easily separated from the clamping groove 3, and the stability of the positioning of the electric lighting coil end 10 is improved. Figure 6

[0034] In order to facilitate the deformation of the clamping groove 3 and reduce the deformation resistance of the clamping groove 3, that is, to reduce the resistance of the clamping block 5 inserted into the clamping groove 3, the utility model is provided with a deformation notch 9 extending from the mouth of the clamping groove 3 to the middle of the clamping groove 3 on the side wall of the clamping groove 3, and the deformation notch 9 and the coil inlet 4 are located on the two side walls of the clamping groove 3 which are parallel to each other. After the deformation notch 9 and the strip-shaped notch are arranged on the two side walls of the clamping groove 3 which are parallel to each other, the overall strength of the clamping groove 3 is reduced, and the clamping groove 3 is more easily deformed after being extruded, so that the clamping block 5 is more easily inserted into the clamping groove 3.
