Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a grounding terminal structure and an air conditioner. Background Technology

[0002] As a widely used household appliance, the electrical safety of air conditioners cannot be ignored. During operation, air conditioners typically protect against electric shock by connecting easily accessible conductive parts to the protective grounding conductor in the fixed wiring (i.e., the power supply's ground wire) to prevent these parts from becoming energized in case of insulation failure. However, air conditioners usually contain multiple components that need to be connected to the protective grounding conductor (power supply's ground wire), often resulting in two grounding wires sharing a single grounding hole.

[0003] In this situation, it is necessary to prevent interference between the tails of the two grounding wires. That is, when assembling the two grounding terminals, the tails of the two grounding terminals need to be manually offset and fixed with screws after maintaining the offset angle. However, this will make the operation difficult and may not guarantee that the two grounding terminals will fit perfectly after assembly. If there is a gap between them, the grounding resistance will increase, which will affect the reliability of grounding.

[0004] In the prior art, patent document CN215870026U discloses a wiring structure to solve the problem of low wiring efficiency between electrical devices. The third terminal described therein is located in the middle part of the wire body. This terminal can simultaneously crimp two wires, allowing each electronic device to connect to only one terminal, simplifying the overall wiring. This technical solution allows two wires to share a single grounding terminal, but it lacks versatility for connecting grounding wires. For example, if the components to which the two grounding wires belong are assembled at different times during production, the terminal cannot be used. Patent document CN104075263A discloses a grounding device including two grounding terminals and a screw. The grounding terminals include pressure plates and two symmetrical limiting arms. The two grounding terminal limiting arms are paired and oriented in opposite directions. The grounding wire is pressed between the pressure plates of the two grounding terminals, achieving the connection between the grounding wire and the metal post. This technical solution's grounding terminal, composed of pressure plates and two symmetrical limiting arms, is suitable for connecting the grounding wire to the metal screw post, but it is not suitable for most sheet metal planar structures in air conditioners, resulting in poor applicability. Utility Model Content

[0005] This utility model provides a grounding terminal structure and an air conditioner, aiming to solve the problem that the existing grounding structure has poor versatility and cannot adapt to the planar structure of sheet metal parts in air conditioners.

[0006] This utility model embodiment provides a grounding terminal structure, including two grounding terminals. Each grounding terminal includes a head and a tail connected to the head. The head includes a protrusion and a recess. The protrusion of one grounding terminal is embedded in the recess of the other grounding terminal, and the protrusion of the other grounding terminal is embedded in the recess of one of the grounding terminals. The tails of the two grounding terminals are staggered.

[0007] Specifically, a grounding hole is provided through the middle of the head, and the grounding holes of the two grounding terminals are connected.

[0008] Specifically, the protrusion and the recess are arranged along the periphery of the grounding hole.

[0009] Specifically, the head is arranged in a ring shape, and the protrusions and recesses are fan-shaped structures.

[0010] Specifically, the head of the same grounding terminal includes a plurality of staggered protrusions and recesses.

[0011] Specifically, multiple protrusions and multiple recesses are symmetrically distributed in the head of the same grounding terminal.

[0012] Specifically, the protrusion is connected to the tail.

[0013] Specifically, the surfaces of the protrusions and recesses are planar.

[0014] Specifically, the protrusion and the recess are integrally formed on the head.

[0015] This utility model embodiment also provides an air conditioner, including the grounding terminal structure described above.

[0016] This utility model embodiment provides a grounding terminal structure and an air conditioner. The grounding terminal structure includes two grounding terminals, each including a head and a tail connected to the head. The head includes a protrusion and a recess, wherein the protrusion of one grounding terminal is embedded in the recess of the other grounding terminal, and the protrusion of the other grounding terminal is embedded in the recess of one of the grounding terminals, and the tails of the two grounding terminals are staggered. The grounding terminal structure of this embodiment is more universal and applicable to the planar structure of sheet metal parts in air conditioners. By ensuring that the two grounding terminals are in contact through the convex-concave fitting structure (i.e., the protrusion and the recess fitting together), the connection gap can be eliminated, and the contact area can be increased, thereby reducing the grounding resistance and improving the grounding reliability. After the two grounding terminals are connected, the two tails are naturally staggered, solving the problem of interference between the tails of the two grounding wires, thus simplifying the assembly operation.

[0033] Please see Figure 1 This utility model provides a grounding terminal structure, including two grounding terminals 10. Each grounding terminal 10 includes a head 11 and a tail 12 connected to the head 11. The head 11 includes a protrusion 111 and a recess 112. The protrusion 111 of one grounding terminal 10 is embedded in the recess 112 of the other grounding terminal 10, and the protrusion 111 of the other grounding terminal 10 is embedded in the recess 112 of one of the grounding terminals 10. The tails 12 of the two grounding terminals 10 are staggered.

[0034] In this embodiment, the grounding terminal structure includes two mating grounding terminals 10, each having a head 11 and a tail 12. The head 11 has a protrusion 111 and a recess 112. The two grounding terminals 10 are connected by the interlocking of the protrusion 111 and the recess 112, and their tails 12 are staggered. This design creates an interlocking structure when the two grounding terminals 10 are connected, preventing loosening due to vibration or external force. Simultaneously, the staggered tails 12 prevent wire interference and improve wiring flexibility.

[0035] For ease of explanation, such as Figure 2-4As shown, the two grounding terminals 10 are divided into a first grounding terminal 10a and a second grounding terminal 10b. The head 11, tail 12, protrusion 111, and recess 112 of the first grounding terminal 10a are respectively referred to as the first head 11a, the first tail 12a, the first protrusion 111a, and the first recess 112a. Similarly, the head 11, tail 12, protrusion 111, and recess 112 of the second grounding terminal 10b are respectively referred to as the second head 11b, the second tail 12b, the second protrusion 111b, and the second recess 112b. When assembling the first grounding terminal 10a and the second grounding terminal 10b, the first protrusion 111a of the first grounding terminal 10a is placed to correspond to the second recess 112b of the second grounding terminal 10b, and the second protrusion 111b of the second grounding terminal 10b is placed to correspond to the first recess 112a of the first grounding terminal 10a, so that the protrusion 111 and the recess 112 of the two grounding terminals 10 are accurately fitted together. At this time, the first tail 12a and the second tail 12b are naturally offset (e.g., at a 90-degree angle). Then, the two grounding terminals 10 are fixed to the sheet metal parts of the air conditioner with screws to complete the connection of the grounding wire.

[0036] In this embodiment, the two grounding terminals 10 are fitted together by a convex-concave interlocking structure (i.e., the protrusion 111 and the recess 112 are interlocked), eliminating connection gaps and increasing the contact area, thereby reducing grounding resistance and improving grounding reliability. After the two grounding terminals 10 are connected, the two tails 12 are naturally staggered, which solves the problem of interference between the tails 12 of the two grounding wires and simplifies the assembly operation.

[0037] In specific implementation, the recessed portion 112 can be configured in two ways. Specifically, the head 11 of the grounding terminal 10 includes an upper surface and a lower surface that are arranged opposite each other. A protrusion 111 is provided on one of the surfaces (such as the upper surface). In this case, the recessed portion 112 does not need to be additionally provided, and the area on that surface without the protrusion 111 can be directly used as the recessed portion 112, while the other surface (such as the lower surface) is set as a planar structure. Alternatively, a recessed hole is additionally provided in the area on that surface without the protrusion 111, and this recessed hole serves as the recessed portion 112. Both of these configuration methods can enable the two grounding terminals to be used together.

[0038] Specifically, such as Figure 1 As shown, a grounding hole 13 is provided through the middle of the head 11, and the grounding holes 13 of the two grounding terminals 10 are connected.

[0039] In this embodiment, in order to enable the grounding terminal 10 to connect to the grounding wire, a grounding hole 13 is provided through the middle of the head 11 of both grounding terminals 10 (same as the above embodiment, refer to...). Figure 2-4The grounding hole 13 of the first grounding terminal 10a is the first grounding hole 13a, and the grounding hole 13 of the second grounding terminal 10b is the second grounding hole 13b. When the protrusion 111 and the recess 112 of the two grounding terminals 10 are fitted together, the first grounding hole 13a and the second grounding hole 13b are connected. The screw passes through the two connected grounding holes 13 to fix the two grounding terminals to the sheet metal parts synchronously, forming a unified grounding connection point to ensure the consistency of the current conduction path.

[0040] After the two grounding terminals 10 in this embodiment are connected, the first grounding hole 13a and the second grounding hole 13b are connected, which optimizes the grounding path. The two grounding holes 13 after being connected can be regarded as a complete grounding hole 13, which can meet the situation where two grounding wires are connected to a complete grounding hole 13, thereby reducing the structural space, reducing the need for additional grounding structures, and improving the safety of electrical connections.

[0041] In practical implementation, the first grounding hole 13a and the second grounding hole 13b can be set to a uniform shape, such as a circle, an ellipse, or a square, to accommodate screws of different shapes.

[0042] Specifically, such as Figure 1 As shown, the protrusion 111 and the recess 112 are provided along the periphery of the grounding hole 13.

[0043] In this embodiment, the protrusion 111 and the recess 112 are distributed around the periphery of the grounding hole 13, making the head 11 structure of the grounding terminal 10 more compact. This allows the pressure when the screw is fixed to be evenly transmitted to the protrusion and recess fitting, enhancing the stability of the fitting and ensuring that the grounding terminal 10 is subjected to uniform force during fitting, thus avoiding deformation or damage caused by local stress concentration.

[0044] In the specific implementation process, when the screw passes through the two connected grounding holes 13 and is tightened, the protrusions 111 and recesses 112 around the grounding holes 13 are subjected to radial pressure, which makes the protrusions 111 and recesses 112 of the two grounding terminals 10 fit together more tightly, thereby improving the reliability of the electrical connection between the two grounding terminals 10.

[0045] Specifically, such as Figure 1 As shown, the head 11 is arranged in a ring shape, and the protrusion 111 and the recess 112 are fan-shaped structures.

[0046] In this embodiment, the head 11 of the annular structure is symmetrically distributed around the grounding hole 13. When the screw passes through the grounding hole 13 for fixing, the annular head 11 can evenly transmit the axial pressure of the screw to the entire plane of the head 11, avoiding deformation or breakage caused by local stress concentration. Compared with non-annular structures (such as square or strip structures), the annular design has higher bending and torsional strength, and can better withstand dynamic loads in vibration environments, making it suitable for high-frequency vibration scenarios such as outdoor units of air conditioners.

[0047] The protrusion 111 and the recess 112 are configured as a fan-shaped structure, which is distributed along the circumference of the ring. The hypotenuse of the fan-shaped structure is aligned with the radius of the ring. When the two grounding terminals 10 are engaged, the hypotenuses of the fan-shaped structure abut against each other, forming a radial constraint force that restricts the rotation and displacement of the two grounding terminals. This design ensures that when the two grounding terminals 10 are subjected to external forces (such as wire pulling), the external force is evenly distributed to the fan-shaped contact surface, effectively avoiding excessive force at a single point and thus improving the overall reliability of the connection.

[0048] In the specific implementation process, the grounding terminals 10 of the two annular heads 11 are fitted together by the fan-shaped protrusions 111 and recesses 112 to form a complete annular structure. The screw passes through the two connected grounding holes 13 for fixation. The inclined sides of the fan-shaped structure abut against each other, thereby restricting the rotation and displacement of the two grounding terminals 10.

[0049] In this embodiment, the engagement of the annular head 11 with the fan-shaped protrusions 111 and recesses 112 results in a more uniform force distribution, a larger contact area, and lower grounding resistance for the two grounding terminals 10. Furthermore, the fan-shaped structure of the protrusions 111 and recesses 112 ensures that the two grounding terminals 10 can still be smoothly engaged after being rotated at a certain angle, thus improving assembly tolerance.

[0050] Specifically, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the head 11 of the same grounding terminal 10 includes a plurality of staggered protrusions 111 and recesses 112.

[0051] In this embodiment, on the head 11 of the same grounding terminal 10, the specific alternation of the protrusion 111 and the recess 112 is as follows: protrusion 111-recess 112-protrusion 111-recess 112... The multiple alternating protrusions 111 and recesses 112 can enhance the fitting strength and positioning accuracy between the two grounding terminals 10, improve the connection stability of the two grounding terminals 10 through multi-point contact, and avoid failure due to excessive force when a single protrusion 111 and recess 112 are fitted together.

[0052] In the specific implementation process, the multiple first protrusions 111a of the first grounding terminal 10a and the multiple second recesses 112b of the second grounding terminal 10b are fitted one by one to form multiple contact points. When the screw is fixed, the multiple contact points share the load to ensure a tight connection between the two grounding terminals 10.

[0053] This embodiment significantly improves the vibration resistance and connection reliability of the grounding terminal structure through the interlocking design of multiple protrusions 111 and recesses 112, and is especially suitable for grounding connections in vibration environments, reducing the loosening and poor contact of the grounding terminal 10 caused by vibration.

[0054] Specifically, multiple protrusions 111 in the head 11 of the same grounding terminal 10 are symmetrically distributed, and multiple recesses 112 in the head 11 of the same grounding terminal 10 are symmetrically distributed.

[0055] In this embodiment, to better achieve a symmetrical distribution, the protrusions 111 and recesses 112 can preferably be set to an even number, such as 2, 4, etc. Figure 2-4 As shown, when two protrusions 111 and two recesses 112 are provided, the total number is four. One protrusion 111 is selected as a reference. This protrusion 111 and the two recesses 112 on either side are at an angle of 90°, and it is at an angle of 180° to the other protrusion 111. Figure 5-7 As shown, when there are 4 protrusions 111 and 4 recesses 112, the total number is 8. Then, one protrusion 111 is selected as the reference. The protrusion 111 and the two recesses 112 on both sides are at an angle of 45°, the protrusion 111 is at an angle of 90° to the nearest protrusion 111, and the protrusion 111 is at an angle of 180° to the farthest protrusion 111. This achieves uniform distribution along the periphery of the grounding hole 13, thereby making the grounding terminal 10 subjected to balanced force in all directions, avoiding deformation or displacement caused by uneven force, and ensuring the stability and consistency of the fit.

[0056] In other implementations, when the grounding hole 13 is a circular hole, the number of protrusions 111 and recesses 112 can also be an odd number, such as 3 or 5. When there are 3 protrusions 111 and 3 recesses 112, the total number is 6. Then, one protrusion 111 is selected as the reference. The protrusion 111 is 60° away from the two recesses 112 on both sides, 120° away from the farthest protrusion 111, and 180° away from the farthest protrusion 111. The same principle applies when there are 5 protrusions 111 and 5 recesses 112, which will not be elaborated here. In summary, as long as the total number of protrusions 111 and recesses 112 can be evenly distributed around the annular circumference of the grounding hole 13, it is acceptable.

[0057] In addition, the design of the annular head 11, the fan-shaped protrusion 111 and the recess 112 makes the current conduction path between the grounding terminals 10 evenly distributed, avoiding the current concentration phenomenon caused by structural asymmetry, thereby reducing the risk of local heating and extending the service life of the grounding terminals 10.

[0058] This embodiment, by setting symmetrical protrusions 111 and recesses 112, enables bidirectional positioning of the two grounding terminals 10 during assembly. Regardless of the angle from which they are fitted, the symmetrical installation of the two grounding terminals 10 is guaranteed, simplifying the assembly operation.

[0059] Specifically, the protrusion 111 is connected to the tail 12.

[0060] In this embodiment, to improve current transmission efficiency, it is preferable to connect the protrusion 111 on the same grounding terminal 10 to the tail 12, thereby shortening the conductive path, reducing resistance, and thus improving current transmission efficiency. In specific implementation, when one protrusion 111 and one recess 112 are provided, the protrusion 111 is directly connected to the tail 12; when multiple protrusions 111 and multiple recesses 112 are provided, one of the protrusions 111 is connected to the tail 12.

[0061] In this embodiment, by connecting the protrusion 111 to the tail 12, the force on the tail 12 can be transmitted to the fitting structure of the head 11 through the protrusion 111, thereby enhancing the structural strength of the entire grounding terminal 10 and facilitating the fixing and stress release of the tail 12 wire.

[0062] In the specific implementation process, when the grounding wire connected to the tail 12 of one of the grounding terminals 10 is pulled, the pulling force is transmitted to the protrusion 111 through the tail 12, and then distributed to the other grounding terminal 10 through the interlocking structure of the protrusion 111 and the recess 112, so as to avoid damage to a single grounding terminal 10 due to excessive force.

[0063] Specifically, such as Figure 1 As shown, the surfaces of the protrusion 111 and the recess 112 are planar.

[0064] In this embodiment, to increase the contact area of ​​the two grounding terminals 10, the surfaces of the protrusion 111 and the recess 112 are preferably made flat, so that the contact is tighter when they are fitted together, thereby reducing the contact resistance and improving the conductivity. Furthermore, the flat protrusion 111 and the recess 112 are easy to manufacture. In actual implementation, the flat protrusion 111 and the recess 112 fit together to form a planar contact. When the screw is tightened, the pressure is evenly distributed on the contact surface, ensuring a good electrical connection.

[0065] Furthermore, because the head 11 is annular, the contact area when the two grounding terminals 10 are connected is larger than that of a non-annular structure, which reduces contact resistance. Moreover, the protrusion 111 and the recess 112 are fan-shaped structures; after the fan-shaped protrusion 111 and recess 112 are fitted together, the arc surface of the protrusion 111 and the arc surface of the recess 112 fit tightly together, further increasing the conductive contact area between the two grounding terminals 10. According to electrical principles, the larger the contact area, the smaller the grounding resistance. Therefore, this design can effectively reduce the resistance value of the grounding circuit, ensure grounding reliability, and meet the safety requirements for electric shock protection of air conditioners.

[0066] Specifically, the protrusion 111 and the recess 112 are integrally formed on the head 11.

[0067] In this embodiment, the integral molding process can eliminate the connection gap between the protrusion 111 and the recess 112 and the head 11, thereby improving the strength and reliability of the entire grounding terminal structure and avoiding corrosion or stress concentration problems caused by gaps.

[0068] In practical implementation, the protrusion 111 and recess 112 can be directly formed onto the head 11 using a one-piece molding process such as stamping or injection molding, eliminating the need for additional connection steps and ensuring the integrity and stability of the structure. Specifically, different one-piece molding processes can be selected depending on the material. When the grounding terminal structure is made of metal, stamping is selected; when the grounding terminal structure is made of plastic, injection molding is selected. In other application scenarios, prefabricated protrusions and recesses can also be fixed to the head 11 using methods such as welding, but one-piece molding is the preferred solution.

[0069] This utility model embodiment also provides an air conditioner, including the grounding terminal structure described above.

[0070] In this embodiment, the grounding terminal structure of any of the above embodiments is applied to an air conditioner, which can solve the connection problem when multiple grounding components in the air conditioner share the grounding hole 13, and improve grounding reliability and safety.

[0071] In practical implementation, especially during the production and assembly of air conditioners, the grounding wires of components that need to be grounded (such as compressors, casings, etc.) are connected to the ground wire of the power supply through a grounding terminal structure to achieve the protective grounding function.

[0072] This embodiment of the grounding terminal structure is applied to air conditioners, which can reduce the structural space of the grounding connection, simplify the assembly operation, and improve production efficiency; it can also ensure low grounding resistance, high grounding reliability, and improve the electrical safety performance of air conditioners.

[0073] In other embodiments, the grounding terminal structure can be applied to different parts of the air conditioner, such as the indoor unit and outdoor unit. The size and shape of the grounding terminal can be adjusted according to the specific installation location and space requirements to adapt to different grounding connection needs.

[0074] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
