[0039] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.
[0040] The inventor of the present application found that in the actual crimping process of the crimping terminal, the forces on the enameled wire and the wiring harness assembly in the crimping terminal are random and varied, and because each strand of the multi-strand wire harness assembly is thin, soft and numerous, the multi-strand wires in the wiring harness assembly often wrap the enameled wire after crimping, resulting in insufficient contact between the serrated spikes on the inner wall of the crimping terminal and the enameled wire, and the serrated spikes on the inner wall of the crimping terminal cannot effectively contact and pierce the insulating paint film of the enameled wire, resulting in poor contact. The embodiment of the present application provides a crimping method for motor wires, which can solve the above-mentioned technical problems.
[0041] Please refer to Figure 1-Figure 5 , the motor wire crimping method provided by the embodiment of the present application includes:
[0042] Step S1, placing the enameled wire 1 on the conductive film 2.
[0043] Step S2 , wrapping the enameled wire 1 in the conductive film 2 to form a conductive wrapping member 3 outside the enameled wire 1 .
[0044] Step S3, placing the conductive wrapping member 3 wrapped with the enameled wire 1 and the wiring harness assembly 4 into the crimping terminal 5 for crimping.
[0045] A spike portion 21 is provided on the surface of the conductive sheath 3 facing the enameled wire 1 .
[0046] In the above steps S1-S3, it is necessary to spread the conductive film 2 flat, and then place the enameled wire 1 on the conductive film 2, and then wind the conductive film 2 through a film rolling device, so that one section of the enameled wire 1 is wrapped in the conductive film 2, and the wound conductive film 2 forms a conductive wrapping member 3, and the unwound part of the conductive film 2 needs to be cut off. Finally, the conductive wrapping member 3 wrapped with the enameled wire 1 and the multi-strand wire harness assembly 4 are placed in the crimping terminal 5, and the crimping height and width are controlled for crimping, wherein the enameled wire 1 is an enameled copper wire or an enameled aluminum wire, and the conductive film 2 is a hard conductive film, which can be the same material as the crimping terminal 5.
[0047] In this crimping method, the enameled wire 1 is first placed on the conductive film 2, and then the enameled wire 1 is wrapped in the conductive film 2, and the conductive film 2 forms a conductive wrapping piece 3 on the outside of the enameled wire 1, and finally the conductive wrapping piece 3 wrapped with the enameled wire 1 and the multi-strand wire harness assembly 4 are placed in the crimping terminal 5 for crimping. Since the enameled wire 1 has been wrapped in the conductive film 2, the multi-strand wires in the harness assembly 4 are not easy to wrap the enameled wire 1, and since the conductive wrapping piece 3 is provided with a spike portion 21 on the surface facing the enameled wire 1, the spike portion 21 on the conductive wrapping piece 3 can effectively contact and pierce the insulating paint film of the enameled wire 1 during the crimping process of the crimping terminal 5, and poor contact problems are not easy to occur.
[0048] In an optional embodiment, step S2 includes: wrapping the conductive film 2 around the outside of the enameled wire 1 to form a conductive wrapping member 3 on the outside of the enameled wire 1 .
[0049] By wrapping the conductive film 2 around the outside of the enameled wire 1, a conductive wrapping member 3 can be formed outside the enameled wire 1. The winding angle of the conductive wrapping member 3 relative to the enameled wire 1 can be selected to be 270°-420°. Generally, a wrapping method is adopted for conductive films 2 with larger widths.
[0050] In another optional embodiment, step S2 includes: spirally winding the conductive film 2 on the outside of the enameled wire 1 to form a conductive wrapping member 3 on the outside of the enameled wire 1 .
[0051] Spirally winding the conductive film 2 around the outside of the enameled wire 1 can not only effectively wrap the enameled wire 1, but also reduce the usage of the conductive film 2 to a certain extent and reduce costs compared to the conductive wrapping member 3 with a winding angle greater than 360° relative to the enameled wire 1. Generally, the enameled wire 1 is wrapped in a spiral winding manner for conductive films 2 with smaller widths.
[0052] An embodiment of the present application also provides a motor stator, including an iron core, an enameled wire 1, a conductive wrapping member 3, a wiring harness assembly 4 and a crimping terminal 5, the enameled wire 1 is wound inside the iron core, and the conductive wrapping member 3 is wound around the outside of the lead wire of the enameled wire 1, a spike portion 21 is provided on the surface of the conductive wrapping member 3 facing the enameled wire 1, the lead wire of the wiring harness assembly 4 and the conductive wrapping member 3 are both provided in the crimping terminal 5, and the lead wire of the wiring harness assembly 4 and the conductive wrapping member 3 are both crimped inside the crimping terminal 5.
[0053] It should be noted that a section of the enameled wire 1 is wound with a conductive wrapping member 3, and the portion of the enameled wire 1 not wound with the conductive wrapping member 3 is wound in the iron core. A plurality of spike portions 21 are arranged at intervals along the winding direction of the conductive wrapping member 3, and each spike portion 21 is strip-shaped, and the length direction of the spike portion 21, the length direction of the enameled wire 1, and the width direction of the conductive wrapping member 3 are all consistent, and the length of the spike portion 21 is equal to the width of the conductive wrapping member 3.
[0054] For the motor stator, the crimping terminal 5 has crimped the lead wire of the wiring harness assembly 4 and the conductive wrapping member 3. The multiple spikes 21 on the surface of the conductive wrapping member 3 facing the enameled wire 1 effectively contact and pierce the insulating paint film of the enameled wire 1 along the circumference of the enameled wire 1. Since the enameled wire 1 is wrapped by the conductive wrapping member 3, it is not easily affected by the wiring harness assembly 4.
[0055] In an optional embodiment, the spike portion 21 includes a spike portion body 211 and spikes 212 , wherein the spike portion body 211 is disposed on the surface of the conductive wrapping member 3 facing the enameled wire 1 , and the spikes 212 are disposed on the surface of the spike portion body 211 facing away from the conductive wrapping member 3 .
[0056] It should be pointed out that the surface of the conductive wrapping member 3 facing the enameled wire 1 is a smooth surface, the spike portion main body 211 is protruding from the surface of the conductive wrapping member 3 facing the enameled wire 1, the surface of the spike portion main body 211 facing the enameled wire 1 is a smooth surface, and the spikes 212 are protruding from the surface of the spike portion main body 211 facing away from the conductive wrapping member 3, wherein more than two spikes 212 can be relatively arranged on the surface of a single spike portion main body 211 facing away from the conductive wrapping member 3, which makes it easier to pierce the insulating paint film of the enameled wire 1.
[0057] When the conductive film 2 is wrapped around the outside of the enameled wire 1, the winding angle of the conductive wrapping member 3 relative to the enameled wire 1 is 270°-420°.
[0058] Exemplarily, when the winding angle of the conductive wrapping member 3 relative to the enameled wire 1 is 270°, the conductive wrapping member 3 does not completely wrap the enameled wire 1, and there is an opening on the conductive wrapping member 3. However, at this time, the sharp thorn portion 21 of the conductive wrapping member 3 can effectively pierce the insulating paint film of the enameled wire 1 under the crimping force, and the enameled wire 1 is less affected by the wiring harness assembly 4.
[0059] When the winding angle of the conductive wrapping member 3 relative to the enameled wire 1 is 360°, the conductive wrapping member 3 completely wraps the enameled wire 1. At this time, the sharp thorn portion 21 of the conductive wrapping member 3 can also effectively pierce the insulating paint film of the enameled wire 1 under the crimping force, and the enameled wire 1 is basically not affected by the wiring harness assembly 4.
[0060] When the winding angle of the conductive wrapping member 3 relative to the enameled wire 1 is 420°, the conductive wrapping member 3 completely wraps the enameled wire 1, and the conductive wrapping member 3 partially overlaps. At this time, the sharp thorn portion 21 of the conductive wrapping member 3 can also effectively pierce the insulating paint film of the enameled wire 1 under the crimping force, and the enameled wire 1 is basically not affected by the wiring harness assembly 4.
[0061] It can be understood that as long as the winding angle of the conductive wrapping member 3 relative to the enameled wire 1 is greater than or equal to 270°, the sharp portion 21 can effectively pierce the insulating paint film of the enameled wire 1, and the enameled wire 1 is less affected by the wiring harness assembly 4. However, if the winding angle of the conductive wrapping member 3 relative to the enameled wire 1 is too large, it may cause waste of the conductive wrapping member 3. Therefore, the winding angle of the conductive wrapping member 3 relative to the enameled wire 1 can be selected within the above range.
[0062] In an optional embodiment, the conductive wrapping member 3 is formed by concentrically or spirally wrapping the conductive film 2 around the enameled wire 1; or, the conductive wrapping member 3 is formed by curling the conductive film 2 into a cylindrical shape, and the enameled wire 1 is inserted into the conductive wrapping member 3.
[0063] It should be noted that when the conductive wrapping member 3 is cylindrical, the enameled wire 1 needs to be rotated and inserted into the through hole of the conductive wrapping member 3. The spike portion 21 of the conductive wrapping member 3 can also effectively pierce the insulating paint film of the enameled wire 1 under the crimping force.
[0064] In an optional embodiment, in the length direction of the enameled wire 1, the width of the conductive wrapping member 3 and the width of the crimping terminal 5 satisfy:
[0065] 0≤W1-W≤10mm, W≤15mm, and W1≤25mm, wherein W is the width of the conductive wrapping member 3 , and W1 is the width of the crimping terminal 5 .
[0066] The width of the crimping terminal 5 needs to be greater than the width of the conductive wrapping member 3. When the conductive wrapping member 3 is placed in the crimping terminal 5 and the crimping terminal 5 is crimped, as long as the conductive wrapping member 3 does not extend out of the crimping terminal 5 at any end in the length direction of the enameled wire 1, the crimping terminal 5 can be squeezed into the conductive wrapping member 3, so that the sharp thorn portion 21 on the conductive wrapping member 3 can effectively pierce the insulating paint film of the enameled wire 1.
[0067] In an optional embodiment, the center value of the outer diameter of the enameled wire 1 is 0.1-2 mm, and the thickness of the conductive wrapping member 3 and the height of the spike portion 21 satisfy:
[0068] H≤5 mm, and 0.04 mm≤D≤0.16 mm, wherein H is the thickness of the conductive package 3 , and D is the height of the spike portion 21 .
[0069] It should be noted that the center value of the outer diameter of the enameled wire 1 refers to the specification value of the outer diameter of the enameled wire 1. For example, when the center value of the outer diameter of the enameled wire 1 is 1 mm, the outer diameter of the enameled wire 1 can be 1±0.05 mm, and the height of the spike portion 21 is the sum of the heights of the spike portion main body 211 and the spike 212.
[0070] Exemplarily, the thickness of the conductive package 3 is 3 mm, 4 mm or 5 mm, and the height of the spike portion 21 is 0.04 mm, 0.1 mm or 0.16 mm.
[0071] In another optional embodiment, the center value of the outer diameter of the enameled wire 1 is 0.4-1.6 mm, and the thickness of the conductive wrapping member 3 and the height of the spike portion 21 satisfy:
[0072] H≤3 mm, and 0.04 mm≤D≤0.08 mm, wherein H is the thickness of the conductive package 3 , and D is the height of the spike portion 21 .
[0073] Exemplarily, the thickness of the conductive package 3 is 1 mm, 2 mm or 3 mm, and the height of the spike portion 21 is 0.04 mm, 0.06 mm or 0.08 mm.
[0074] The embodiment of the present application further provides a compressor, comprising the above-mentioned motor stator. The technical effect of the compressor is substantially the same as the technical effect of the above-mentioned motor stator, which will not be described in detail here.
[0075] In summary, the embodiments of the present application provide a method for crimping a motor wire, a motor stator and a compressor. During the crimping process of the enameled wire 1, the enameled wire 1 is first placed on a conductive film 2, and then the enameled wire 1 is wrapped in the conductive film 2. The conductive film 2 forms a conductive wrapping member 3 on the outside of the enameled wire 1. Finally, the conductive wrapping member 3 wrapped with the enameled wire 1 and the multi-strand wire harness assembly 4 are placed in the crimping terminal 5 for crimping. Since the enameled wire 1 has been wrapped in the conductive film 2, and the winding angle of the conductive wrapping member 3 relative to the enameled wire 1 is greater than or equal to 270°, the multi-strand wires in the harness assembly 4 are not easy to affect the enameled wire 1, and since the conductive wrapping member 3 is provided with a plurality of spike portions 21 on the surface facing the enameled wire 1, the plurality of spike portions 21 on the conductive wrapping member 3 can effectively contact and pierce the insulating paint film of the enameled wire 1 during the crimping process of the crimping terminal 5, and poor contact problems are not easy to occur.
[0076] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
