Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0030] In the description of the utility model, it is understood that the orientation words such as '' front, back, up, down, left, right '' '' horizontal, vertical, perpendicular, horizontal '' and '' top, bottom '' and the like indicated orientation or positional relationship usually based on the orientation or positional relationship shown in the drawing, just for the convenience of describing the utility model and simplifying the description, in the absence of the opposite statement, these orientation words do not indicate and imply the device or element must have a particular orientation or be constructed and operated in a particular orientation, therefore it can not be understood as the limitation of the protection scope of the utility model;The orientation words '' inside, outside '' refer to the inside and outside relative to the contour of each component.

[0031] For the convenience of description, spatial relative terms such as '' above'', '' above'', '' upper surface'', '' upper '' and the like can be used here to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawing. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawing. For example, if the device in the drawing is inverted, the device described as '' above '' or '' above '' other devices or structures will be positioned '' below '' or '' below '' other devices or structures. Thus, the exemplary term '' above '' can include both '' above '' and '' below '' orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative description used here is interpreted accordingly.

[0032] In addition, it should be noted that the use of '' first'', '' second '' and the like to limit parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, therefore it can not be understood as the limitation of the protection scope of the utility model.

[0033] For reference Figures 1 to 9 As shown in the drawing, according to the embodiment of the utility model, a wire clamp assembly is provided, which comprises an outlet clamp, a power cord 1 and a terminal block 2, the outlet clamp is formed with an outlet hole 3, the power cord 1 passes through the outlet hole 3, the terminal block 2 is provided with a first terminal post 4, the power cord 1 has a first metal bare section, and the first metal bare section is wound around the first terminal post 4.

[0034] In the technical scheme, the first terminal post 4 is arranged on the terminal block 2, the power cord 1 has the first metal bare section, and then the first metal bare section of the power cord 1 is wound on the first terminal post 4, which is equivalent to positioning the welding point formed between the power cord 1 and the first terminal post 4, so that the operator is more convenient when welding the power cord 1 and the first terminal post 4, and the welding effect is better.

[0035] It should be noted that the original stator structure needs to be sleeved with the joint sleeve 17 after the power line 1 is welded, so as to insulate the welding point and the winding 19 below, and the power line 1 and the joint sleeve 17 are also adhered to the stator core 18 by the adhesive tape to position the power line 1 and the joint sleeve 17, so that the process operation is complicated. After the wiring board 2 is arranged in the application, the welding point formed between the power line 1 and the first terminal post 4 is separated from the winding 19 by the wiring board 2, so that the joint sleeve 17 can be omitted. At the same time, the welding of the power line 1 on the first terminal post 4 also serves as the positioning of the power line 1, so that the power line 1 does not need to be positioned by the adhesive tape, thereby simplifying the process operation steps and improving the production efficiency.

[0036] Referring to Figure 1 and Figure 2 , the wiring board 2 is provided with a thermal protector 5 on the side away from the first terminal post 4.

[0037] In the embodiment, if the thermal protector 5 and the first terminal post 4 are arranged on the same side of the wiring board 2, the wiring board 2 needs to be designed to be longer to distribute the thermal protector 5 and the first terminal post 4 on the wiring board 2.

At the same time, the arrangement of the thermal protector 5 on the side of the wiring board 2 away from the first terminal post 4 facilitates the contact between the thermal protector 5 and the winding 19, so that the thermal protector 5 can better perceive the temperature of the winding 19, thereby helping the thermal protector 5 to work more effectively.

[0038] Referring to Figure 1 , the number of power lines 1 is multiple, the number of first terminal posts 4 is multiple, the first terminal posts 4 are distributed at intervals on the wiring board 2, the thermal protector 5 is connected with the first electric wire 6, the first electric wire 6 has a second metal bare section, the second metal bare section and the first metal bare section of one of the power lines 1 are wound around one of the first terminal posts 4, and the first metal bare sections of the remaining power lines 1 are wound around the remaining first terminal posts 4, respectively.

[0039] The second metal bare section of the first electric wire 6 on the thermal protector 5 and the first metal bare section of one of the power supply wires 1 are wound together on one of the first connecting posts 4, which is equivalent to the welding point formed between the first electric wire 6 on the thermal protector 5 and the first connecting post 4 being positioned, so that the operator is more convenient when welding the first electric wire 6 and the first connecting post 4, and the welding effect is better. In this way, the joint sleeve 17 can also be omitted at the welding point on the first electric wire 6, and the first electric wire 6 is positioned by using adhesive tape, thereby further simplifying the process operation steps and further improving the production efficiency. The distance between the first connecting posts 4 is designed in advance, so that the welding point spacing between the power supply wires 1 can be planned in advance, so that the welding point spacing does not have to be controlled by manual positioning operation, thereby being able to standardize the control of the welding point spacing and further upgrading the motor product process. It should be noted that the number of power supply wires 1 is three, and the number of wire outlet holes 3 formed on the wire outlet clamp is three, and the three power supply wires 1 pass through the three wire outlet holes 3 respectively.

[0040] Referring to Figure 1 As shown in the figure, the second connecting post 7 is also arranged on the connecting plate 2, and the second connecting post 7 and the first connecting post 4 are on the same side of the connecting plate 2. The second electric wire 8 is also connected to the thermal protector 5, and the second electric wire 8 has a third metal bare section, and the third metal bare section is wound around the second connecting post 7.

[0041] In this embodiment, the third metal bare section of the second electric wire 8 on the thermal protector 5 is wound around the second connecting post 7, which is equivalent to the welding point formed between the second electric wire 8 on the thermal protector 5 and the second connecting post 7 being positioned, so that the operator is more convenient when welding the second electric wire 8 and the second connecting post 7, and the welding effect is better. In this way, the joint sleeve 17 can also be omitted at the welding point on the second electric wire 8, and the second electric wire 8 is positioned by using adhesive tape, thereby further simplifying the process operation steps and further improving the production efficiency.

[0042] It should be noted that one of the power supply wires 1 and the first electric wire 6 are wound together on the same first connecting post 4 in order to connect the power supply wire 1 to the first electric wire 6 through the first connecting post 4, and the remaining power supply wires 1 are connected to the winding 19 through the remaining first connecting posts 4, and the second electric wire 8 is connected to the winding 19 through the second connecting post 7.

[0045] Referring to Figure 2 , it is shown that the side of the terminal board 2 away from the first terminal post 4 is provided with a clamping structure 10, and the clamping structure 10 clamps the thermal protector 5.

[0046] In the embodiment, the thermal protector 5 is clamped by the clamping structure 10, so that the thermal protector 5 is assembled on the terminal board 2 in a simple way. It should be noted that the clamping structure 10 is a clamping jaw, and the number of the clamping jaw is three, of which two clamping jaws clamp the thermal protector 5 from the two sides of the thermal protector 5, and the remaining one clamping jaw clamps the thermal protector 5 from the tail of the thermal protector 5. The first electric wire 6 and the second electric wire 8 are led out from the front end of the thermal protector 5.
