[0043] Embodiment 1:

[0044] The present embodiment provides a clamp plate for laying electric wire 9, which comprises a plate body 3, one plate surface of the plate body 3 is provided with a through groove 31, in use, the electric wire 9 is laid in the through groove 31, so that the electric wire 9 is more standardized, at this time, the through groove 31 is a wire groove, specifically, the through groove 31 can be a straight groove, a curved groove or a serpentine groove, the cross-sectional shape can be semicircular, square or irregular, and best of all, the through groove 31 is a straight groove and the cross-sectional shape is a minor arc, the central angle of the minor arc is 85°-89°, when the electric wire 9 is placed in the through groove 31, the outer wall of the electric wire 9 is in interference fit with the groove wall of the through groove 31, so as to obtain a higher protection level.

[0045] A first groove 32 is arranged on the wall of the through slot 31, and specifically, the first groove 32 is arranged on the middle section of the through slot 31, i.e. the middle section of the through slot 31 is recessed to form the first groove 32. When the electric wire 9 is installed in the through slot 31 in an interference fit, the first groove 32 can accommodate the interference amount generated by the compression of the wall of the through slot 31 in the interference fit, so as to reduce the deformation of the wall of the through slot 31 and the clamp plate, avoid the edge of the clamp plate from being raised, and make the contact between the electric wire 9 and the wall of the through slot 31 more closely, so as to achieve a better protection effect.

[0046] The plate body 3 is an integral structure made of an elastic material, so that the wall of the through slot 31 and the whole plate body 3 can be slightly deformed to achieve an interference fit when in use, so as to make the contact between the plate body 3 and the electric wire 9 and other contact surfaces more closely, and thus achieve a higher protection level. Preferably, the elastic material is rubber or plastic.

[0047] Embodiment 2

[0048] This embodiment is a preferred embodiment of Embodiment 1. In this embodiment, the plate body 3 is a flat plate, the through slot 31 is arranged on one surface of the plate body 3, and the two ends of the plate body 3 through which the through slot 31 extends are respectively the front end of the plate body 3 and the rear end of the plate body 3.

[0049] As a more preferred embodiment of this embodiment, the plate body 3 in this embodiment is provided with mounting structures on the left and right sides thereof. The mounting structures are used for positioning and limiting the plate body 3 relative to the external environment when in use. Specifically, the mounting structures include a first block 4 and a second block 5, as shown in Figures 1 to 5 The first block 4 is arranged at the front end of the side wall of the plate body 3, and the second block 5 is arranged at the rear end of the side wall of the plate body 3. A gap is arranged between the first block 4 and the second block 5. When in use, the user inserts an external object into the gap between the first block 4 and the second block 5, and makes the first block 4 abut against one side surface of the external object and the second block 5 abut against the other side surface of the external object, so as to position and limit the plate body 3 relative to the external object.

[0050] Embodiment 3

[0051] As a more preferred embodiment of the above-mentioned embodiments, the first block 4 in the embodiment is provided with a clearance gap 7 at the position far away from the front end of the plate body 3. When the clamp plate provided by the application is used on a motor, the circumferential wall of the stator 10 of the motor is clamped in the gap between the first block 4 and the second block 5, and the front end of the clamp plate is directed towards the outside of the stator 10. If the plate body 3 and the first block 4 and the second block 5 together form a square structure, the edge of the front end of the first block 4 (at the position far away from the plate body 3) will protrude out of the outer wall of the stator 10, thereby interfering with external objects. The provision of the clearance gap 7 can form a clearance for external objects, thereby avoiding interference with external objects.

[0052] Specifically, the clearance gap 7 makes the front end of the plate body 3 and the front end of the first block 4 form an arc-shaped structure surface.

[0053] Embodiment 4

[0054] As a more preferred embodiment of the above-mentioned embodiments, the plate body 3 in the embodiment is provided with a protrusion 8 on another plate surface (also referred to as the side plate surface provided with the through slot 31). Specifically, the protrusion 8 is integrally formed with the plate body 3, and the shape of the protrusion 8 is square, rectangular, hexagonal, semispherical, irregular, or the like. The number of protrusions 8 can be one or more. Preferably, the shape of the protrusion 8 is square, and the number of protrusions 8 is two, which are arranged at intervals.

[0055] With this structure, a second groove 102 adapted to the protrusion 8 is provided on the external object on which the plate body 3 provided by the embodiment is installed. When installed, the protrusion 8 is embedded in the second groove 102 to form positioning and limiting. Together with the above-mentioned installation structure, the purpose of stably installing the plate body 3 on the external object is achieved. Preferably, the protrusion 8 protrudes in the same direction as the width direction of the gap between the first block 4 and the second block 5.

[0056] Embodiment 5

In this way, the upper clamp plate 1 is not provided with the protrusion 8, and the lower clamp plate 2 is provided with the protrusion 8.

[0058] When the upper clamp plate 1 and the lower clamp plate 2 are combined, they are aligned vertically, and the through slot 31 on the upper clamp plate 1 and the through slot 31 on the lower clamp plate 2 are directly opposite and spliced to form a wire passing hole, which can clamp and hold the electric wire 9. The clearance gap 7 on the upper clamp plate 1 and the clearance gap 7 on the lower clamp plate 2 correspond vertically.

[0059] With the above structure, the wire outlet sheath provided by the embodiment is used, the electric wire 9 is inserted into the wire passing hole, and the electric wire 9 is in interference fit with the slot wall of the through slot 31 of the upper clamping plate 1 and the slot wall of the through slot 31 of the lower clamping plate 2. Since the first groove 32 is arranged on the slot wall of the through slot 31, the first groove 32 can accommodate the part of the interference fit, so that the upper clamping plate 1 and the lower clamping plate 2 do not have the edge lifting condition, the slot wall of the through slot 31 and the outer wall of the electric wire 9 are more closely attached, and it is more impossible for foreign matters or dust to pass through between the slot wall of the through slot 31 and the electric wire 9. Therefore, the protection level of the wire outlet sheath is higher.

[0060] Embodiment 6:

[0061] The embodiment provides an electric machine, which uses the above wire outlet sheath to lay the electric wire 9 on the stator 10, and the electric wire 9 is in interference fit with the slot wall of the through slot 31.
