Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor components, in particular to a short-circuit sheet, a motor and a household appliance. Background Art
[0002] At present, inner rotor variable frequency motors are increasingly used in household appliances. In order to achieve short circuit of two or more connection points on the motor, a wire structure with terminals is usually used. For connection points that are close to each other, the wire length is short, and crimping of the terminals at both ends is difficult or even impossible.
[0003] The shortcomings of the existing technology are that the structure with wire strip terminals is more expensive than the metal stamping connecting plate structure; for connection points that are close to each other, if the wire is required to be straightened, the wire length is short, the wire connection terminal process is difficult to operate, or even impossible to operate, and the metal stamping short-circuit plate is not limited by the short distance; the distance between the two circular terminals of the wire strip terminal structure is affected by the cutting of the wire and the connection process, and the distance fluctuation is larger than that of the metal stamping short-circuit plate; for short-circuiting more than two connection points, the short-circuit plate structure is easier to implement than the wire structure. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art. To achieve the above purpose, a short-circuit sheet, a motor and a household appliance are used to solve the problems raised in the above background technology.
[0005] A short-circuit plate, used for a motor, wherein the motor is provided with a first connection point and a second connection point, the short-circuit plate comprises a first terminal and a second terminal, the first terminal is electrically connected to the first connection point, and the second terminal is electrically connected to the second connection point;
[0006] The short-circuit piece further includes a conductor disposed between the first terminal and the second terminal and integrally connected to the first terminal and the second terminal.
[0007] As a further solution of the utility model: one end of the conductor connected to the first terminal is provided with a bending portion for fitting and fixing to the first connection point; or one end of the conductor connected to the second terminal is provided with a bending portion for fitting and fixing to the second connection point. When implementing connections between electronic devices, it is usually necessary to ensure the stability and reliability of the connection. In order to achieve this goal, it is often necessary to use the first connection point and the second connection point for connection. However, due to various reasons, these two points may not be at the same height. At this time, the bending portion plays a vital role.
[0008] When the first connection point and the second connection point are arranged at different heights, the bending portion enables the first terminal or the second terminal to better fit the two connection points. This fit not only increases the stability of the connection, but also improves the connection reliability of the short circuit. By optimizing the fit between the terminal and the connection point, the stress caused by the height difference can be reduced, thereby extending the service life of the connector.
[0009] In addition, the design of the bend can be adjusted according to actual needs to adapt to connection points of different heights and angles. This flexibility allows the bend to play its advantages in various complex environments and ensure stable connections between electronic devices. Therefore, when faced with connection points of different heights, a properly designed bend is the key factor in achieving reliable connections.
[0010] As a further solution of the utility model: the first terminal and the second terminal are both circular terminals, and circular fixing holes are provided on the first terminal and the second terminal, and the first terminal and the second terminal are fixed to the first connection point and the second connection point by fastening screws. This design allows the two terminals to be conveniently fixed to other components or circuits, because the circular fixing holes can adapt to various fixing requirements, such as screws or bolts. This design improves the stability and reliability of the equipment and prevents the terminals from loosening or falling off.
[0011] As a further solution of the present invention: the diameter of the first terminal and the second terminal is greater than 20 mm. Its function is to ensure that the terminals can meet specific application or design requirements.
[0012] As a further solution of the utility model: the first terminal and the second terminal and the conductor are a structure formed by metal stamping. Metal stamping is a process method for stamping metal plates or pipes. Through this process, the terminal and the conductor can be directly connected together to form a complete structure. This connection method can reduce the number of connection points, improve the integrity and stability of the structure, and also reduce electrical faults caused by poor connection.
[0013] As a further solution of the utility model: the conductor is in the shape of a long strip, and the two ends of the conductor along the length direction are integrally connected to the first terminal and the second terminal respectively. The conductor with a long strip structure can provide a larger conductive area, making the transmission of current smoother, reducing resistance, and improving conductive efficiency. This structure also has good flexibility and plasticity, and can be bent or shaped according to actual needs, which is convenient for installation and use.
[0014] As a further solution of the utility model: the conductor is provided with a galvanized sheet, the thickness of the galvanized sheet is 0.8 mm to 1.0 mm. The zinc layer can provide a certain degree of corrosion protection, so that it has a longer service life in certain applications.
[0015] As a further solution of the utility model: the bending angle range of the bending portion is 0° to 90°. The angle range provides great flexibility, so that the component can be bent appropriately according to the needs of actual application.

[0017] The technical solution of the third aspect: a household appliance, comprising:
[0018] A motor, wherein the motor adopts a short-circuit plate as described in any one of the above items.
[0019] Compared with the prior art, the utility model has the following technical effects:
[0020] By adopting the above technical solution and using a quick connection or self-locking connection mechanism, the first terminal and the second terminal can be quickly and easily connected to the first connection point and the second connection point, thereby reducing the difficulty of operation and improving the connection efficiency;
[0021] In order to ensure the stability of the connection, consider using a quick fixing method between the first terminal and the first connection point or between the second terminal and the second connection point, which can be quickly fixed and prevent the connection point from loosening or falling off when subjected to external force; reasonably design the shape, size and surface treatment of the first terminal and the second terminal to better match the first connection point and the second connection point. Increase the contact area, reduce the connection resistance, and improve the connection stability;
[0022] By providing a long strip of metal conductor, and providing a circular first terminal and a second terminal on the conductor, and cooperating with the bent portion to fit the connection point of the motor, the problem of high structural cost of the wire strip terminal in the prior art and the problem that the distance between the two circular terminals of the wire strip terminal structure is affected by the cutting of the wire and the connection process are solved.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Please refer to Figure 1 In an embodiment of the utility model, a short-circuit sheet is used for a motor 1, and a first connection point 2 and a second connection point 7 are provided on the motor;
[0029] The short-circuit piece includes a first terminal 3 and a second terminal 4, wherein the first terminal 3 is electrically connected to the first connection point, and the second terminal 4 is electrically connected to the second connection point 7; the short-circuit piece also includes a conductor 5 disposed between the first terminal 3 and the second terminal 4 and integrally connected to the first terminal 3 and the second terminal 4, and one end of the conductor 5 connected to the first terminal 3 is provided with a bending portion 51 for being fitted and fixed to the first connection point 2; or one end of the conductor 5 connected to the second terminal 4 is provided with a bending portion for being fitted and fixed to the second connection point 7. When the first connection point 2 and the second connection point 7 are disposed at different heights, the bending portion 51 enables the first terminal 3 or the second terminal 4 to better fit the first connection point 2 or the second connection point 7, thereby increasing the reliability of the short-circuit connection.
[0030] When implementing the connection between electronic devices, it is usually necessary to ensure the stability and reliability of the connection. In order to achieve this goal, it is often necessary to use the first connection point 2 and the second connection point 7 for connection. However, due to various reasons, these two points may not be at the same height. At this time, the bending part plays a vital role.
[0031] When the first connection point 2 and the second connection point 7 are arranged at different heights, the bent portion 51 enables the first terminal 3 or the second terminal 4 to better fit the two connection points. This fit not only increases the stability of the connection, but also improves the reliability of the short-circuit connection. By optimizing the fit between the terminal and the connection point, the stress caused by the height difference can be reduced, thereby extending the service life of the connector.
[0032] In this embodiment, Figure 2 As shown, the figure is a schematic diagram of the structure of the first terminal 3 and the second terminal 4. The first terminal 3 and the second terminal 4 are both circular terminals, and circular fixing holes 6 are opened on the first terminal 3 and the second terminal 4. The first terminal 3 and the second terminal 4 are fixed to the first connection point 2 and the second connection point 7 by fastening screws 61. Such a design enables it to be stably fixed on the motor and ensures good contact between the conductor 5 and the first connection point 2 and the second connection point 7, thereby achieving effective connection of the motor.
[0033] In a specific embodiment, the entire short-circuit piece is fixed at the required first connection point 2 and second connection point 7 by fastening screws 61 through the round strip terminals on the ends of the first terminal 3 and the second terminal 4, thereby achieving short circuit of the first connection point 2 and the second connection point 7.
[0034] In a specific implementation, the size range of the first terminal 3 and the second terminal 4 is greater than 20 mm. The first terminal 3, the second terminal 4 and the conductor 5 are integrally formed by metal stamping. This not only simplifies the production process, but also improves the strength and reliability of the overall structure.
[0035] In a specific embodiment, the conductor 5 adopts a long strip structure, and the two ends of the conductor 5 along the length direction are integrally connected to the first terminal 3 and the second terminal 4, respectively, and a galvanized sheet is provided. The galvanized sheet has excellent anti-corrosion performance and can increase the service life of the conductor 5. At the same time, the thickness of the galvanized sheet is 0.8 mm to 1.0 mm, and a specific value of 0.8 mm or 1.0 mm can be taken. This thickness range allows the conductor 5 to have sufficient mechanical strength and ensure good conductivity.
[0036] The bending angle of the bending portion ranges from 0° to 90°. This feature increases the flexibility of the design, allowing the connection device to be adjusted accordingly according to actual application scenarios and requirements.
[0037] In this embodiment, the bending angle of the bending portion 51 can be 90°.

[0039] The technical solution of the third aspect: a household appliance, comprising a motor, wherein the motor adopts a short-circuit plate as described in any one of the above items. Since the household appliance adopts the short-circuit plate with the above structural features, the problem of high structural cost of the wire strip terminal in the prior art and the problem that the distance between the two circular terminals of the wire strip terminal structure is affected by the cutting wire and the connection process are solved. Among them, the household appliances include but are not limited to washing machines, dryers, etc.
