Description

Technical Field

[0001] The present disclosure belongs to the technical field of compressors, and particularly relates to a compressor wiring assembly, a compressor, and a refrigeration device. Background Art

[0002] Currently in the household appliance industry, the requirements for insulation withstand voltage are getting higher and higher. Inside the compressor, due to the presence of liquid refrigerant, when the liquid refrigerant comes into contact with the terminal post, it will cause a decrease in insulation resistance, increasing potential safety hazards in the system. Therefore, in related technologies, nitrile rubber or other insulating material structures are generally used to wrap the copper pin of the terminal post, and integral injection molding or injection gluing is used at the other end to achieve a sealing effect. However, the sealing performance between the terminal post and the socket end of these methods is not ideal. Due to the existence of socket mold tolerances or the aging of parts after long-term use, the refrigerant will still come into contact with the terminal post. Summary of the Invention

[0048] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of this disclosure will be clearly and completely described below in conjunction with specific embodiments of this disclosure and the corresponding drawings. Apparently, the described embodiments are only a part rather than all of the embodiments of this disclosure. Based on the embodiments in this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this disclosure.

[0049] Combined with Figures 1 to 7 As shown, an embodiment of this disclosure provides a compressor wiring assembly, including: a socket body 1 and a terminal 2; a jack 3 is provided on the socket body 1, and the terminal 2 can be inserted into the jack 3; a first sealing structure is provided around the jack 3, and a second sealing structure is provided on the terminal 2; when the terminal 2 is inserted into the jack 3, the first sealing structure is in sealing contact with the second sealing structure to realize the sealed connection between the terminal 2 and the socket body.

[0050] The compressor wiring assembly is installed inside the sealed housing of a hermetic electric compressor and serves to connect the terminal 2 of an external cable to the wiring terminal of the motor. The compressor wiring assembly of this disclosure is arranged inside the sealed housing of the compressor. The wiring terminal of the motor is connected to the socket, and then the terminal 2 of the external cable is inserted into the socket to realize the connection between the motor and the external cable. To improve the sealing performance at the mating part between the terminal 2 of the external cable and the jack 3 of the socket, a first sealing structure, such as a spiked part 4 or a deformed part 5, is provided on the socket body 1 around the jack 3, and a second sealing structure, such as a deformed part 5 or a spiked part 4, is sleeved on the terminal 2. When the terminal 2 and the jack 3 are mated, the first sealing structure is in close contact with the second sealing structure to completely isolate the internal terminal 2 from the external refrigerant, realizing the sealed connection between the terminal 2 and the socket body 1.

[0051] In this embodiment, three jacks 3 are provided on the socket body 1, and correspondingly, three terminal posts 2 are also provided. The three terminal posts 2 are fixedly installed through a wiring board 16. For the cooperation between the three jacks 3 and the terminal posts 2, the first sealing structure and the second sealing structure in any embodiment of the present disclosure are provided to achieve the sealed connection between the terminal post 2 and the socket body 1.

[0052] In some embodiments, the first sealing structure is provided with a spike portion 4 extending towards the second sealing structure, and the second sealing structure is provided with a deformation portion 5 that can be pierced by the spike portion 4 to achieve circumferential sealing; or, the second sealing structure is provided with a spike portion 4 extending towards the first sealing structure, and the first sealing structure is provided with a deformation portion 5 that can be pierced by the spike portion 4 to achieve circumferential sealing.

[0053] In this embodiment, the sealing structure is designed as the spike portion 4 and the deformation portion 5, which are arranged opposite to each other. When the terminal post 2 is matched with the jack 3, the spike portion 4 can pierce into the deformation portion 5 or cause the deformation portion 5 to be extruded and deformed. Since the deformation portion 5 has a certain extrusion force, after the spike portion 4 pierces in, it can closely fit the surface of the spike portion 4, thereby forming a non-planar sealing structure with a better sealing effect than the planar sealing, completely isolating the internal terminal post 2 from the external refrigerant, and achieving the sealed connection between the terminal post 2 and the socket body.

[0054] In some embodiments, the spike portion 4 includes a first spike structure 6 and a second spike structure 7. The first spike structure 6 and the second spike structure 7 are concentrically arranged around the axis of the jack 3 or the terminal post 2, and the first spike structure 6 is arranged on the outer periphery of the second spike structure 7 away from the axis.

[0055] In this embodiment, preferably, a two-layer spike structure with circumferential concentricity is adopted. Through simulation and experiments, when the spike portion 4 is made into three layers or more, the mutual stress between the spike portion 4 and the deformation portion 5 becomes larger, which will affect the service life of the deformation portion 5. And the experiments show that too many spike portions 4 not only fail to play a sealing role, but also damage the structure of the deformation portion 5, resulting in a decline in its own mechanical properties; when the spike portion 4 is one layer, the complete sealing effect cannot be achieved. Therefore, it is best to make the spike portion 4 into two layers.

[0056] In some embodiments, both the first spike structure 6 and the second spike structure 7 are inclined towards the axis of the jack 3 or the terminal post 2, and the inclination angle of the second spike structure 7 is greater than that of the first spike structure 6. Experiments prove that when the inclination angle of the inner spike structure is greater than that of the outer spike structure, it can better ensure the better stiffness of the spike portion 4 itself and also ensure a better sealing and insulating effect.

[0057] In some embodiments, when the terminal 2 is inserted into the jack 3, the distance from the sharp corner of the first spike structure 6 to the side surface of the terminal 2 is L1, and the distance from the sharp corner of the second spike structure 7 to the side surface of the terminal 2 is L2, where L1>0 and the value range of L2 / L1 is 0.3 to 0.45. When the sizes of the first spike structure 6 and the second spike structure 7 meet the above numerical range, it is possible to achieve the best sealing and insulating effect while ensuring the firmness of the spike part 4 itself, and the structure can also be optimized to reduce unnecessary material waste.

[0058] In some embodiments, the first spike structure 6 includes a first side surface 8 and a second side surface 9. The first side surface 8 faces the axis of the jack 3 or the terminal 2, and the second side surface 9 faces away from the axis of the jack 3 or the terminal 2. The first side surface 8 and the second side surface 9 intersect at the end to form a spike shape that can pierce into the deformed part 5.

[0059] and / or,

[0060] The second spike structure 7 includes a third side surface 10 and a fourth side surface 11. The third side surface 10 faces the axis of the jack 3 or the terminal 2, and the fourth side surface 11 faces away from the axis of the jack 3 or the terminal 2. The third side surface 10 and the fourth side surface 11 intersect at the end to form a spike shape that can pierce into the deformed part 5.

[0061] In some embodiments, when the first side surface 8 and the fourth side surface 11 are included and the first sealing structure includes the spike part 4, the first sealing structure includes an annular sealing structure body 15. The first spike structure 6 and the second spike structure 7 are arranged on the sealing structure body 15. The first side surface 8 of the first spike structure 6 intersects the outer peripheral wall of the sealing structure body 15 at a first inflection point 12, and the fourth side surface 11 of the second spike structure 7 intersects the inner peripheral wall of the sealing structure body 15 at a second inflection point 13, satisfying:

[0062] The distance from the first inflection point 12 to the side surface of the terminal 2 is L3, and the distance from the second inflection point 13 to the side surface of the terminal 2 is L4, where the value range of L3 / L4 is 2 to 2.15. Preferably, L3 / L4 = 2.1;

[0063] and / or,

[0064] The distance between the sharp corner of the first spike structure 6 and the first inflection point 12 along the axis of the socket 3 or the terminal 2 is H1, and the distance between the sharp corner of the second spike structure 7 and the second inflection point 13 along the axis of the socket 3 or the terminal 2 is H2. The value range of H1 / H2 is 0.73 to 0.76. Preferably, H1 / H2 = 0.76.

[0065] When the sizes of the first spike structure 6 and the second spike structure 7 meet the above numerical range, it is possible to achieve the best sealing and insulation effect while ensuring the firmness of the spike part 4 itself, and the structure can also be optimized to reduce unnecessary material waste.

[0066] In some embodiments, when the second side 9, the third side 10, and the fourth side 11 are included, the angle between the second side 9 and the cross-section of the socket 3 or the terminal 2 is θ1, the angle between the third side 10 and the cross-section of the socket 3 or the terminal 2 is θ2, and the angle between the fourth side 11 and the cross-section of the socket 3 or the terminal 2 is θ3, satisfying:

[0067] θ3 > θ2, and the value range of θ2 / θ1 is 0.54 to 0.85. Preferably, θ2 / θ1 = 0.58;

[0068] and / or,

[0069] 76° ≤ θ1 ≤ 83°, 45° ≤ θ2 ≤ 65°, 65° ≤ θ3 ≤ 70°.

[0070] When the angles of the second side 9, the third side 10, and the fourth side 11 meet the above numerical range, the stiffness of the spike part 4 is optimal, the best sealing and insulation effect can be achieved, the structure can also be optimized, and unnecessary material waste can be reduced.

[0071] In some embodiments, when the first side 8 and the third side 10 are included, the first side 8 and the third side 10 are arc-shaped surfaces. The arc radius corresponding to the first side 8 is R1, and the arc radius corresponding to the second side 9 is R2. The value range of R1 / R2 is 0.8 to 0.89.

[0072] When the radian of the first side 8 and the second side 9 meets the above numerical range, the stiffness of the spike part 4 is optimal, the best sealing and insulation effect can be achieved, the structure can also be optimized, and unnecessary material waste can be reduced.

[0073] In some embodiments, when the first side surface 8 is included, the first side surface 8 is an arc surface, the arc radius corresponding to the first side surface 8 is R1, and the distance between the sharp angle of the first spike structure 6 and the first inflection point 12 along the axis direction of the jack 3 or the terminal 2 is H1, satisfying R1 > H1;

[0074] and / or,

[0075] When the third side surface 10 is included, the third side surface 10 is an arc surface, the arc radius corresponding to the third side surface 10 is R2, and the distance between the sharp angle of the second spike structure 7 and the second inflection point 13 along the axis direction of the jack 3 or the terminal 2 is H2, satisfying R2 > H2.

[0076] When the sizes of the first spike structure 6 and the second spike structure 7 meet the above numerical ranges, the stiffness of the spike portion 4 is optimal, which can achieve the best sealing and insulating effect, and can also optimize the structure and reduce unnecessary material waste.

[0077] Verified by experiments, the natural frequency can reflect the stiffness of an object. The higher the frequency, the higher the stiffness. When the size of the first sealing structure in this embodiment meets the above numerical ranges, the stiffness of the sharp structure will increase by about 27%, and at the same time, it has good insertion performance and the best sealing and insulating effect.

[0078] In some embodiments, when the first side surface 8 and the second side surface 9 are included, the first side surface 8 is an arc surface and the second side surface 9 is a plane, that is, the first spike structure 6 has a shape with an outer arc surface and an inner plane;

[0079] and / or,

[0080] When the third side surface 10 and the fourth side surface 11 are included, the third side surface 10 is an arc surface and the fourth side surface 11 is a plane, that is, the second spike structure 7 has a shape with an outer arc surface and an inner plane.

[0081] Thus, the first spike structure 6 and the second spike structure 7 can ensure the optimal stiffness, can achieve the best sealing and insulating effect, and can also optimize the structure and reduce unnecessary material waste.

[0082] At the same time, the deformation portion 5 functions to cooperate with the spike portion 4 for sealing. According to the following dimensions, the deformation portion 5 can closely fit the spike portion 4 of the present disclosure and achieve the best sealing effect.

[0083] In some embodiments, an arc-shaped groove 14 concave axially is provided on the end face of the deformation part 5 facing the spike part 4. The radius of the arc-shaped groove 14 is D1. When the terminal 2 is inserted into the jack 3, when the distance from the sharp angle of the first spike structure 6 to the side face of the terminal 2 is L1 and the distance from the sharp angle of the second spike structure 7 to the side face of the terminal 2 is L2, the value range of L3 / D1 is less than 0.83, and the value range of L2 / D1 is less than 0.49.

[0084] In some embodiments, when the second sealing structure includes a deformation part 5, the deformation part 5 is made of a material resistant to fluorine and easy to magnetize, such as a rubber magnet material. When there is current passing through the terminal 2 during operation, a magnetic field is formed to magnetize the deformation part 5, so that the deformation part 5 tightly attracts the terminal 2. When the cooperation between the deformation part 5 and the terminal 2 is not tight or it becomes loose after long-term operation, it can still achieve the sealing effect.

[0085] According to Figure 8 the comparison result of the insulation resistance between the related technology shown and the present disclosure, the insulation resistance of the compressor using the compressor terminal assembly of the present disclosure has increased by about 1.9 times; according to Figure 9 the comparison of the natural frequencies between the other dimensions shown and the preferred dimensions of the present disclosure, when the preferred dimensions of the compressor terminal assembly of the present disclosure are adopted, the natural frequency of the sealing structure has increased by 27%. The natural frequency can reflect the stiffness of an object. The higher the frequency, the higher the stiffness, that is, the stiffness of the sealing structure, such as the spike part, has increased by 27%.

[0086] Therefore, the compressor terminal 2 of the embodiments of the present disclosure can improve the overall insulation performance of the compressor, meet higher requirements of customers; increase the operation reliability of the compressor, making the overall system operate stably; increase the assembly stability of the socket, and it is not easy to fall off in a bumpy operation environment.

[0088] A refrigeration device adopts the above-mentioned compressor terminal assembly.

[0089] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned advantageous ways can be freely combined and superimposed.

[0090] The above are only the preferred embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure. The above is only the preferred implementation manner of the present disclosure. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present disclosure, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present disclosure.
