[0002] As the power element of the air conditioner compressor, the motor has a direct impact on the quality and performance of the air conditioner. The lead wire of the motor is the wire that can connect the internal circuit of the motor with the external circuit, and it is led out from the lead wire assembly such as the lead box.

[0003] In the prior art, the lead wire assembly of the motor includes two upper and lower matching blocks. The lead wires are pre-crimped at the terminals on the matching blocks, and the terminals are plugged into the matching blocks. In order to separate multiple lead wires, a separator block is provided on the matching block, and a slot corresponding to the separator block is provided on the other matching block. In this way, the lead wires can be fixed in the lead box by plugging and matching the two matching blocks.

[0004] However, due to the opening of the slot, in order to ensure the depth of the slot, the thickness of the corresponding matching block must meet certain conditions, which leads to an increase in the cost of the lead wire assembly during the production process, and further leads to an increase in the cost of the motor and the compressor. Summary of the invention

[0005] The object of the present invention is to provide a lead wire assembly, a motor and a compressor, which solves the problem in the prior art that when manufacturing the lead wire assembly, the overall thickness needs to be ensured due to the need to consider the groove depth, which leads to an increase in the overall production cost and causes an increase in the cost of the motor and the compressor.

The separation component has a step. When the second matching block is engaged with the first matching block, the protrusion is engaged on the step to separate two adjacent leads.

[0010] Optionally, the partition assembly comprises:

[0011] A first boss, fixed to the first matching block; and

[0012] The second boss is disposed on the first boss, and a step is formed between the second boss and the first boss.

[0013] Optionally, the thickness of the second boss is smaller than the thickness of the first boss, so that the side surface of the second boss and the top surface of the first boss form the separation gap.

[0014] Optionally, the second boss is located on one side of the first boss, so that the step is L-shaped.

[0015] Optionally, the second boss has a positioning block, a separation gap is formed between the positioning block and the first boss, and the protrusion has a connecting block inserted into the separation gap and connected with the positioning block.

[0016] Optionally, the positioning block is provided with a guiding inclined surface facing the connecting block; and / or the connecting block is provided with a connecting inclined surface matching with the guiding inclined surface.

[0017] Optionally, the positioning block and the connecting block both extend along the length direction of the protrusion.

[0018] Optionally, the lead wire assembly further includes:

[0019] A plurality of buckles are distributed at intervals on the first matching block and can be snap-connected with the second matching block.

[0020] In a second aspect, the present invention provides a motor comprising a lead wire assembly as described in any one of the first aspects.

[0021] In a third aspect, the present invention provides a compressor, comprising: the motor as described in the second aspect.

[0022] Beneficial effects of the present invention:

[0023] By respectively arranging the separation component and the protrusion on the first matching block and the second matching block, the protrusion can be plugged and matched with the separation component while the first matching block and the second matching block fix the multiple leads, so that the multiple leads are separated smoothly. In this way, the first matching block and the second matching block do not need to be grooved separately during production, and the wall thickness of the first matching block and the second matching block can be kept at a small thickness, which is conducive to saving the cost of the lead wire assembly during the production process, thereby reducing the overall production cost of the motor and the compressor.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] The invention provides a lead wire assembly, a motor and a compressor.

[0039] Reference Figure 1 and Figure 2 The lead-out assembly includes a first matching block 1 and a second matching block 2. The first matching block 1 is provided with a plurality of leads at intervals, and a separation assembly 3 is provided between two adjacent leads; the second matching block 2 is clamped with the first matching block 1 to fix the leads, and a protrusion 4 is provided at a position corresponding to the second matching block 2 and the separation assembly 3, and the separation assembly 3 has a step. When the second matching block 2 is clamped with the first matching block 1, the protrusion 4 is fitted on the step to separate two adjacent leads.

[0040] Specifically, the first matching block 1 is located at the lower side of the second matching block 2. Three sockets are spaced apart on the bottom plate of the first matching block 1. The plugs of the lead-out terminals are inserted through the sockets and then pass through the bottom plate. Each plug corresponds to a lead, and the above-mentioned partition component 3 is arranged between two adjacent lead-out terminals. The second matching block 2 is formed with a cavity 21. After the side wall of the second matching block 2 is connected to the first matching block 1, a cavity is formed between the two. The protrusion 4 is fixed on the cavity wall of the cavity 21 and extends toward the side close to the partition component 3.

[0041] The size of the cavity 21 of the second matching block 2 can be slightly larger than that of the first matching block 1, so that the outer wall of the first matching block 1 can just fit with the cavity wall of the cavity 21, so that the protrusion 4 can form a plug-in fit with the partition component 3. The first matching block 1 and the second matching block 2 are both shell-shaped, and their shapes can be designed according to the actual installation position. The wall thickness can meet the installation requirements, and the present invention does not limit this.

[0042] By respectively arranging the separation component 3 and the protrusion 4 on the first matching block 1 and the second matching block 2, the first matching block 1 and the second matching block 2 can fix the multiple leads while the protrusion 4 can be plugged and matched with the separation component 3 to smoothly separate the multiple leads. In this way, the first matching block 1 and the second matching block 2 do not need to be grooved separately during production, and the wall thickness of the first matching block 1 and the second matching block 2 can be kept at a small thickness, which is conducive to saving the cost of the lead-out wire assembly during the production process.

[0043] Reference Figures 2 to 4 In some embodiments of the present invention, the partition assembly 3 includes a first boss 31 and a second boss 32. The first boss 31 is fixed to the first matching block 1; the second boss 32 is disposed on the first boss 31, and a step is formed between the second boss 32 and the first boss 31 for the protrusion 4 to be inserted.

[0044] Specifically, the first boss 31 is fixed on the top wall of the first matching block 1 and extends along the first direction. The fixing method can be clamping, welding or bonding, etc. The second boss 32 is located on the top wall of the first boss 31. The two can be integrally formed to facilitate processing and production. The second boss 32 can also extend along the first direction. A notch or a slot can be provided on the upper side of the second boss 32 to form a step. The second boss 32 can also cooperate with the first boss 31 to form a step. The specific shape of the step can be designed according to the actual production difficulty.

[0045] The first boss 31 and the second boss 32 are provided to form a step. When the first matching block 1 is plugged into the second matching block 2, the protrusion 4 can be inserted into the step, so that the protrusion 4 cooperates with the separation component 3 to smoothly separate two adjacent leads.

[0046] In some embodiments of the present invention, the thickness of the second boss 32 is less than the thickness of the first boss 31, so that the side surface of the second boss 32 forms a step with the top surface of the first boss 31. Specifically, the two second bosses 32 are located on the side where the two first bosses 31 are close to each other, and one side of the second boss 32 is flush with the first boss 31, so that the step is L-shaped. By forming an L-shaped step, its opening is larger to facilitate the insertion of the protrusion 4 into the step. It should be understood that the second boss 32 can also be located in the middle of the first boss 31, so that the partition component 3 is convex as a whole and forms two steps. In the middle of the protrusion 4, a concave notch can be opened so that the two sides of the protrusion 4 can be correspondingly inserted into the two steps, thereby also realizing the plug-in fit between the protrusion 4 and the partition component 3.

[0047] The size of the protrusion 4 can be designed according to the size of the step. The depth of the protrusion 4 is equal to the height of the step, so that when the protrusion 4 is inserted into the step, it can just overlap with the second boss 32, and the first boss 31 can also maintain contact with the second matching block 2.

[0048] Reference Figures 5 to 8 In some embodiments of the present invention, the second boss 32 has a positioning block 321, a separation gap 33 is formed between the positioning block 321 and the first boss 31, and the protrusion 4 has a connecting block 41 inserted into the separation gap 33 and connected with the positioning block 321. The positioning block 321 and the connecting block 41 both extend along the length direction of the protrusion 4. The positioning block 321 is provided with a guiding inclined surface 322 facing the connecting block 41. The connecting block 41 is provided with a connecting inclined surface 411 that matches the guiding inclined surface 322.

[0049] Specifically, the positioning block 321 is located on the side of the second boss 32 away from the first boss 31, and can be integrally formed with the second boss 32 to facilitate production and processing. The positioning block 321 extends along the first direction, and a separation gap 33 is formed between one side of the positioning block 321 and the first boss 31 for the connection block 41 to be inserted. A guide slope 322 is provided on the other side of the positioning block 321, and a chamfer can be provided on the top of the second boss 32 to form an arc transition with the guide slope 322. The connection block 41 is located on the side of the protrusion 4 away from the second matching block 2, and its shape and structure are the same as those of the positioning block 321, and will not be described in detail here.

[0050] By providing the positioning block 321 and the connecting block 41, when the protrusion 4 is inserted into the step, the positioning block 321 and the connecting block 41 can also be staggered with each other under the action of the guiding bevel 322 and the connecting bevel 411, and the connecting block 41 can be correspondingly inserted into the partition notch 33 and form a snap connection with the positioning block 321, so that the protrusion 4 and the second boss 32 are snap-fitted and fixed together, so as to improve the connection strength between the second matching block 2 and the first matching block 1.

[0051] Reference Figure 1 and Figure 3 In some embodiments of the present invention, the lead wire assembly further includes a plurality of buckles 5. The plurality of buckles 5 are spaced apart in the first mating block 1 and can be snapped with the second mating block 2. Specifically, the first mating block 1 and the second mating block 2 can both be rectangular, and the buckle 5 is provided at each of the four corners of the first mating block 1, while the four corners of the second mating block 2 are provided with corresponding snap holes that can be snapped with the buckle 5. It should be understood that the specific number and distribution of the buckles 5 can be designed according to the sizes of the first mating block 1 and the second mating block 2, and the present invention does not limit this.

[0052] By arranging buckles 5 at the four corners of the first mating block 1, the first mating block 1 and the second mating block 2 are snap-fitted at their edges by the buckles 5, and the protrusion 4 and the partition assembly 3 are located at the middle of the first mating block 1. The positioning block 321 and the connecting block 41 can be snap-fitted at the middle, so that the first mating block 1 and the second mating block 2 are snap-fitted at their middle and edges, thereby effectively improving the connection strength between the two.

[0053] The motor comprises a lead wire assembly as in any of the above embodiments. The motor can be connected to a compressor of an air conditioner.

[0054] The compressor includes: a motor as in any of the above embodiments.
