[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] Combine the following Figure 1-Figure 9 The multi-bridge terminal 40 , the motor 100 , and the compressor 1000 according to the embodiment of the present invention are described in detail.

[0039] Reference Figure 1-Figure 3 As shown, the multi-bridge terminal 40 according to the embodiment of the present invention is a conductive member and includes a plurality of terminal portions 41, two adjacent terminal portions 41 are connected by a connecting neck 42, each terminal portion 41 includes a body piece 45, a first wing piece 46 and a second wing piece 47, one end of the first wing piece 46 and one end of the second wing piece 47 are connected to the body piece 45, and the body pieces 45 of two adjacent terminal portions 41 of the multi-bridge terminal 40 are connected by the connecting neck 42. Optionally, as Figure 1 and Figure 3 As shown, the multi-bridge terminal 40 includes a first terminal portion 411 and a second terminal portion 412. The body piece 45, the first wing piece 46 and the second wing piece 47 of the first terminal portion 411 and the second terminal portion 412 form a crimping space 48 for wrapping the wire 60. Each terminal portion 41 can crimp at least one wire 60. The connecting neck 42 connects the wires 60 in the two adjacent terminal portions 41 by connecting to the body pieces 45 of the two adjacent terminal portions 41. After the multi-bridge terminal 40 conducts the crimped multiple wires 60, it can be connected to the external circuit, thereby connecting the multiple wires 60 to the external circuit.

[0040] In the related art, taking the compressor 1000 as an example, since the lead wire is used as the intermediate medium to connect the stator coil and the external circuit, during the stator production process, there are problems such as increased workload in the process, slow production rhythm in time, and increased cost. In addition, when a single metal terminal is used to crimp multiple wires 60, there is a problem that the single metal terminal cannot completely crimp all wires 60. The multi-bridge terminal 40 of the embodiment of the present invention can directly connect the wire 60 to the external circuit, omitting the lead wire, reducing the process of crimping the lead wire, reducing the cost, and improving the production efficiency. At the same time, the multi-bridge terminal 40 includes multiple terminal parts 41, which have sufficient space compared to a single metal terminal and can crimp multiple wires 60.

[0041] According to the multi-bridge terminal 40 of the embodiment of the present invention, since the multi-bridge terminal 40 is a conductive member and includes a plurality of terminal parts 41, two adjacent terminal parts 41 are connected by a connecting neck 42, the lead wires are omitted, the process of crimping the lead wires is reduced, the cost is reduced, and the production efficiency is improved. At the same time, the multi-bridge terminal 40 includes a plurality of terminal parts 41, which can crimp multiple wires 60 compared to a single metal terminal.

[0042] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the other end of the first wing 46 is connected to the other end of the second wing 47, and the other end of the first wing 46 and the other end of the second wing 47 are separated from the body sheet 45. Figure 1 and Figure 3 As shown, under the pressure of the die knife, the first terminal portion 411 and the second terminal portion 412 gradually bend the first wing 46 and the second wing 47 inward until they are completely closed and deformed into an "m" shape. The first wing 46 and the second wing 47 are separated from the body sheet 45 at one end away from the body sheet 45, which helps to increase the crimping space 48. In some embodiments not shown, the first wing 46 and the second wing 47 can be separated from the end away from the body sheet 45, the crimping space 48 is increased, and the wire 60 can be connected at the same time.

[0043] In some embodiments of the present invention, reference Figure 2 As shown, the arrangement direction of two adjacent terminal portions 41 is the length direction of the connecting neck 42. The length of the connecting neck 42 does not exceed 3 mm, and the width of the connecting neck 42 does not exceed 2 mm. Figure 2As shown, the length direction of the connecting neck 42 is the Y direction, and the width direction of the connecting neck 42 is the X direction. The length direction Y of the connecting neck 42 is perpendicular to the width direction X of the connecting neck 42. The length of the connecting neck 42 is A, and the value range of A is 0<A≤3mm. Optionally, A can be 1mm, 2mm, 3mm. Of course, A can also be other values ​​between 0-3mm. The width of the connecting neck 42 is B, and the value range of B is 0<B≤2mm. Optionally, B can be 1mm, 2mm. Of course, B can also be other values ​​between 0-2mm. Maintaining the length A and width B of the connecting neck 42 within the above range is conducive to cost saving.

[0044] like Figure 8 As shown, taking the two-bridge terminal including two terminal parts 41 as an example, it can be seen from the temperature rise-current carrying relationship diagram of the two-bridge terminal that the overall temperature rise of the two-bridge terminal gradually increases with the increase of the current carrying, roughly in the shape of a binomial parabola, and the fitting degree reaches 99.9%. When the two-bridge terminal carries a current of 20A, the temperature rise is the largest, does not exceed 30°C, and there is still a certain margin. It can be seen that although the cross-sectional area of ​​the connecting neck 42 of the two-bridge terminal suddenly decreases, it can also achieve a reliable connection between the wire group and the external circuit.

[0045] In some embodiments of the present invention, reference Figure 1 and Figure 3 As shown, the first wing 46, the main body 45 and the second wing 47 enclose a crimping space 48 for crimping a wire harness, and a protrusion 49 is provided on the inner wall of the crimping space 48, and the protrusion 49 is used to pierce the insulating sheath of the crimped wire harness. Optionally, the wire 60 is made of copper wire and an insulating sheath, and the insulating sheath is wrapped on the outside of the copper wire. The protrusion 49 pierces the insulating sheath, so that the wire 60 in the crimping space 48 can be connected. At the same time, after the protrusion 49 pierces the insulating sheath of the wire 60, a blocking force will be generated on the insulating sheath of the wire 60, which is conducive to fixing the wire 60 in the crimping space 48 and preventing it from loosening.

[0046] In some embodiments of the present invention, reference Figure 1 As shown, the protrusion 49 is constructed as a plurality of U-shaped protrusion burrs arranged in parallel, and the height of the protrusion burrs protruding from the inner wall does not exceed 2 μm. Figure 1 As shown, a plurality of U-shaped raised burrs are evenly distributed on the inner side of the first terminal portion 411 and the second terminal portion 412 along the length direction Y of the connecting neck 42. Optionally, the height of the raised burrs protruding from the inner wall can be 1 μm, 2 μm, or other values ​​between 0 and 2 μm. Controlling the height of the raised burrs protruding from the inner wall within 2 μm can effectively reduce the occupation of the crimping space 48 by the raised portion 49.

[0047] In some embodiments of the present invention, the number of terminal parts 41 does not exceed 4. Optionally, the multi-bridge terminal 40 may include two terminal parts 41, three terminal parts 41, or four terminal parts 41. The more terminal parts 41 there are, the more wires 60 can be crimped.

[0048] In some embodiments of the present invention, reference Figure 3 As shown, the direction from the body sheet 45 to the connection between the first wing sheet 46 and the second wing sheet 47 is the height direction of the terminal portion 41, and the direction from the first wing sheet 46 to the second wing sheet 47 is the width direction of the terminal portion 41. The height of the terminal portion 41 does not exceed 2.5 mm, and the width of the terminal portion 41 does not exceed 4 mm. Figure 3 As shown, after crimping the wire 60, the height of the "m"-shaped first terminal portion 411 and the second terminal portion 412 does not exceed 2.5 mm, and the width does not exceed 4 mm. The height direction of the first terminal portion 411 and the second terminal portion 412 is the Y direction, and the width direction of the first terminal portion 411 and the second terminal portion 412 is the X direction. The height of the terminal portion 41 along the Y direction is C, and the value range of the height C is 0<C≤2.5 mm. Optionally, the height C can be 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm. Of course, the height C can also be other values ​​between 0-2.5 mm.

[0049] The width of the terminal portion 41 along the X direction is D, and the value range of the width D is 0<D≤4mm. Optionally, the width D can be 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4mm. Of course, the width D can also be other values ​​between 0-4mm.
