Description

Technical Field

[0001] The present invention and the technical field of air conditioning, in particular, relate to a motor terminal and an air conditioner. Background Art

[0002] At present, the wiring terminals and motor wire access terminals of air conditioner motors are assembled through locking pieces, wherein the locking pieces are designed with the buckle protrusion facing inwards. However, with this connection structure, the locking pieces are not easy to identify when the motor wiring terminals and motor wire access terminals are disassembled. In addition, the surface of the locking piece is relatively smooth, and there is no point of force when applying force outward to disassemble the locking piece, so disassembly is very inconvenient. In addition, the motor terminals have strong and weak current distribution, and a special structure needs to be designed to ensure its safety. Summary of the invention

[0003] The problem solved by the invention is to provide a motor terminal which is convenient for assembly and disassembly.

[0004] In order to solve the above problems, the present invention provides a motor terminal, comprising:

[0005] A motor terminal, wherein the motor terminal has at least one access portion and at least one locking catch;

[0006] At least one motor line access terminal, used to plug and cooperate with the access portion to achieve electrical connection between the motor line and the motor terminal;

[0007] Among them, the motor line access terminal includes at least one locking piece, which has a protrusion facing away from the motor terminal, and the protrusion is matched with the lock to achieve relative fixation of the motor terminal and the motor line access terminal.

[0008] Therefore, when the motor terminal and the motor wire access terminal are disassembled, the wire locking piece is easier to identify and press, and the wire locking piece can be easily removed by simply pressing vertically downward and inward.

[0009] Furthermore, the assembly gap between the two sides of the locking piece and the locking buckle is 1.2-1.8 mm.

[0010] By increasing the gaps on both sides of the assembly, the problem of small assembly gaps of traditional lock wire pieces and difficulty in distinguishing after being assembled into one is overcome, making it easy to distinguish the lock wire piece and the lock buckle assembled with it, thereby achieving the purpose of quickly identifying the lock wire piece.

[0011] Furthermore, a guide portion is provided on one side of the raised portion of the thread locking piece close to the free end of the thread locking piece.

[0012] Therefore, the wire locking piece can be made to pass through the lock buckle more smoothly, which facilitates the installation operation of the motor terminal and the motor wire access terminal.

[0013] Furthermore, the guide portion includes a ramp structure.

[0014] Furthermore, the guide portion includes a planar structure connected to the ramp structure.

[0015] Therefore, when removing the motor wire access terminal, the guide portion arranged at the free end of the wire locking piece can provide a force point for the operator to press, further facilitating the removal of the wire locking piece.

[0016] Furthermore, wire locking pieces are respectively provided on two opposite sides of the motor wire access terminal.

[0017] By fixing the motor on the side opposite to the motor wire entry terminal, the stability of its installation can be improved.

[0018] Furthermore, the motor terminal comprises:

[0019] A first motor wire access terminal, wherein a wire locking piece is provided on a first side of the first motor wire access terminal;

[0020] A second motor wire access terminal, a first side of which is provided with a wire locking piece, and a second side of the second motor wire access terminal abuts against a second side of the first motor wire access terminal.

[0021] Therefore, the parallel motor line access terminals are closely attached to each other to perform positioning, thereby also achieving reliable fixation of the motor line access terminals.

[0022] Furthermore, the access unit includes:

[0023] A first access portion, the first access portion being connected to a weak current terminal of the motor;

[0024] The second access portion is connected to the high-voltage terminal of the motor, and the second access portion protrudes a predetermined distance relative to the first access portion in a direction away from the motor terminal.

[0025] Since the motor terminals have strong current and weak current access, the strong current access part is set to have a desktop structure, thereby increasing the creepage distance and forming a protective structure for isolating strong and weak currents.

[0026] Furthermore, the predetermined distance value is 4-8 mm.

[0027] According to another aspect of the present invention, there is provided an air conditioner, comprising the motor terminal as described above.

[0028] The beneficial effects of the air conditioner and the motor terminal are the same, which will not be described again here. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] The present invention provides a motor terminal. Figure 1 FIG. 1 is a schematic diagram of the structure of the motor terminal according to an embodiment of the present invention. Figure 1 As shown, the motor terminal includes a motor terminal 1 and at least one motor line access terminal 2. The motor terminal 1 has at least one access portion and at least one locking buckle 11 with a hollow structure; the at least one motor line access terminal 2 is used to plug and match with the access portion to achieve electrical connection between the motor line and the motor terminal 1.

[0041] Specifically, the motor line access terminal 2 includes at least one locking piece 21 , which is at a certain distance from the motor line access terminal 2 , and the connection portion between the locking piece 21 and the motor line access terminal 2 is elastic so that the free end can be pressed toward the motor line access terminal 2 .

[0042] Figure 2a-2c The figure is a schematic diagram of the connection structure between the locking piece and the locking buckle according to an embodiment of the present invention. Figure 3 This is a cross-sectional view of the connection structure between the locking piece and the lock buckle according to an embodiment of the present invention. Figure 2a-2c and Figure 3 As shown, the locking piece 21 has a protrusion 212 facing away from the motor terminal 1. During installation, the free end of the locking piece 21 and the protrusion 212 can pass through the hollow part of the lock buckle 11 in a pressed state. When the locking piece 21 reaches a specified position and stops pressing, the protrusion 212 cooperates with the lock buckle 11 to achieve relative fixation of the motor terminal 1 and the motor line access terminal 2.

[0043] Therefore, by changing the fixing method of the locking piece 21 to a protrusion facing away from the motor terminal 1, the locking piece 21 is easier to identify and press when the motor terminal 1 and the motor wire access terminal 2 are disassembled. The locking piece 21 can be easily removed by simply pressing vertically downward and inward.

[0044] Furthermore, in some embodiments, the assembly gap a between the two sides of the locking piece 21 and the two sides of the locking buckle 11 is maintained at 1.2-1.8 mm. Figure 4 This is a front view of the connection structure between the locking piece and the lock buckle according to an embodiment of the present invention. Figure 4 As shown, by increasing the gaps on both sides of the assembly, the problem of small assembly gaps of traditional lock wire pieces and difficulty in distinguishing after being assembled into one is overcome, so that the lock wire piece 21 and the lock buckle 11 assembled therewith are easy to distinguish, thereby achieving the purpose of quickly identifying the lock wire piece 21.

[0045] In order to further facilitate the disassembly and assembly of the motor terminal 1 and the motor line access terminal 2, in some embodiments, a guide portion 211 is provided on one side of the protrusion 212 of the locking piece 21 close to the free end of the locking piece 21. Specifically, the guide portion 211 can be provided with a slope structure 2112. Figure 2a-2c , wherein the guide portion 211 has a slope structure 2112. Thus, by setting the slope structure 2112, the locking piece 21 can be made smoother when passing through the lock buckle 11, which facilitates the installation operation of the motor terminal 1 and the motor wire access terminal 2.

[0046] Furthermore, the guide portion 211 also has a planar structure 2112 connected to the ramp structure 2112, that is, the guide portion 211 is set as an inclined step structure. Therefore, when removing the motor wire access terminal 2, the guide portion 211 set at the free end of the locking piece 21 can also provide a fulcrum for the operator to press, thereby further facilitating the removal of the locking piece 21.

[0047] In order to achieve reliable fixation of the motor line access terminal 2, in some embodiments, the motor terminal includes a first motor line access terminal and a second motor line access terminal in parallel. Figure 5a Schematic diagram of the structure of an embodiment of the motor line access terminal of the present invention. Figure 5a As shown, a wire locking piece 21 is provided on the first side of the motor line access terminal; the second side of the motor line access terminal 2 abuts against another motor line access terminal 2 .

[0048] Therefore, the motor line access terminals 2 can be placed close to each other to limit the position, thereby achieving reliable fixation of the motor line access terminals 2.

[0049] In other embodiments, wire locking pieces 21 are respectively provided on two opposite sides of the motor line access terminal 2 . Figure 5b FIG. 1 is a schematic diagram of another embodiment of the motor line access terminal of the present invention. Figure 5b As shown, a wire locking piece 21 is designed before and after the motor line access terminal 2, so as to improve the stability of its installation by fixing the opposite sides.

[0050] Figure 6 FIG. 2 is a cross-sectional view of a motor terminal structure according to an embodiment of the present invention. Figure 6 As shown, since the motor terminal has strong current and weak current access, the strong current access part is provided with a table-type structure, thereby increasing the creepage distance. Specifically, the access part includes a first access part 12 and a second access part 13. Among them, the first access part 12 is connected to the weak current terminal of the motor; the second access part 13 is connected to the strong current terminal of the motor, so the creepage requirement of the second access part 13 is higher than the creepage distance of the first access part 12, so a boss structure is provided in the second access part 13, that is, the second access part 13 is provided to protrude a predetermined distance relative to the first access part 12 in the direction away from the motor terminal 1. Among them, the predetermined distance value b is 4-8mm.

[0051] In a second exemplary embodiment of the present invention, an air conditioner is provided, comprising the motor terminal as described above.

[0052] The air conditioner motor terminal structure of the present invention is described in detail below in conjunction with specific embodiments.

[0053] Embodiment 1

[0054] Figure 7 FIG. 1 is a bottom view of the motor terminal structure according to an embodiment of the present invention. Figure 7 As shown, the motor terminal includes 1 motor terminal 1 and 5 motor line access terminals 2. The motor terminal 1 has 5 access parts and 6 locking buckles 11 with a hollow structure; the 5 motor line access terminals 2 are used to plug and match with the 5 access parts to achieve electrical connection between the motor line and the motor terminal 1. By using 5 motor line access terminals 2, the motor cables are aggregated to form an overall motor terminal, so that there will be no omissions or misconnections due to too many terminal blocks, which greatly improves assembly efficiency and accuracy and facilitates wiring.

[0055] Specifically, the five motor line access terminals 2 include one large terminal 201 and four small terminals 202, wherein one large terminal 201 has two locking pieces 21, and the four small terminals 202 have only one locking piece 21. The large terminal 201 is connected to 220V strong electricity, and a locking piece 21 is designed at the front and back of the large terminal 201 to improve the stability of its connection; the remaining four small terminals 202 are all 12V weak electricity, and each terminal is also provided with a locking piece 21, and the other side is limited by the close contact between the parallel terminals to achieve reliable fixation of the small terminal 202.

[0056] The locking piece 21 is provided with a protrusion 212 in a direction away from the motor terminal 1. With this structural setting of the locking piece 21, it is easy to identify the locking piece 21 when removing the motor terminal, and the locking piece 21 can be removed by simply pressing downward and inward on the vertical surface, which is convenient for exerting force.

[0057] Furthermore, a 5mm table-type structure is designed for the access part of the motor terminal 1 corresponding to the large terminal 201 to increase the creepage distance, which is more conducive to connecting the large terminal 201 to form 220V strong electricity and play a role in isolation and protection. The other four small terminals 202 are all 12V weak electricity, and the creepage distance requirements are relatively small.

[0058] In this embodiment, the assembly gap between the two sides of the locking piece 21 and the two sides of the lock buckle 11 is 1.5 mm, and the top of the locking piece 21 is designed to be an inclined step type, which serves as an assembly guide and increases the fulcrum. This structure is conducive to distinguishing the locking piece 21 from the lock buckle 11 assembled therewith, achieving the effect of quick identification and easy disassembly.

[0059] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
