[0002] In the related art, the circuit board of the valve assembly is used to control the valve component to open or close the flow channel. The circuit board in the valve assembly and the valve component are electrically connected through the plug and the connector through installation and matching. In the actual manufacturing process, due to the manufacturing tolerance of the plug and the connector, the plug is difficult to insert into the connector when there is a deviation in the thickness of the plug and the spatial width of the corresponding position of the connector or the installation position. Summary of the invention

[0003] The purpose of the present invention is to solve at least one of the problems in the background technology and to provide a valve assembly.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A valve assembly comprises a valve component and a circuit board. The valve component comprises a connecting joint, which is electrically connected to the circuit board. The connecting joint comprises a main body, an elastic part, and a contact part. The main body, the elastic part, and the contact part are integrally arranged or the elastic part is connected to at least one of the main body and the contact part. The valve component comprises an electrical connection part, which is electrically connected to the main body and / or the contact part. An installation space is present between the main body and the contact part, at least a portion of the installation space is located between the main body and the contact part, at least a portion of the electrical connection part is located in the installation space, and the contact part and / or the main body can be displaced at least along the width direction of the installation space as the elastic part is elastically deformed.

[0006] In the valve assembly of the above technical solution, when the power connection part is assembled into the installation space, the contact part and / or the main body part can be displaced at least along the width direction of the installation space as the elastic part deforms elastically, so that when there is a thickness deviation or a position deviation in the power connection part, the power connection part can also extend into the connecting joint.

[0007] The present invention also describes an assembly method of a valve assembly, wherein the valve assembly comprises a valve component and at least two connecting joints, wherein the two electrical connection parts are defined as a first electrical connection part and a second electrical connection part, and the two connecting joints are defined as a first connecting joint and a second connecting joint;

[0008] When the first power connection portion is inserted into the first installation space, the contact portion and / or the body portion of the first connection connector can be displaced at least once along the width direction of the first installation space;

[0009] When the second power connection portion is inserted into the second installation space, the contact portion and / or the body portion of the first connection connector can at least undergo a second displacement along the width direction of the first installation space;

[0010] The primary displacement and the secondary displacement can be performed simultaneously or successively.

[0011] In the assembly method of the valve assembly of the above technical solution, the contact portion and / or the main body portion can undergo a primary displacement to compensate for the installation deviation between the contact portion and the connecting joint caused by the processing thickness deviation or position deviation of the electrical connection portion, and can also undergo a secondary displacement to further compensate for the installation deviation caused by the deviation in the distance between different electrical connection portions and the distance between different connecting joints.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Other embodiments obtained by technical personnel in the field without creative work all belong to the protection scope of the present invention. In addition, it should be understood that the following words indicating orientation or position relationship such as "up", "down", "left", "right", "longitudinal", "lateral", "inside", "outside", "vertical", "horizontal", "top", "bottom", etc. are only based on the orientation or position relationship shown in the drawings, only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0033] like Figure 1-Figure 16 As shown, a valve assembly 100 of the present embodiment includes a box body 1, a valve component 2, and a circuit board 3. At least a portion of the valve component 2 is located in the box body 1. The valve component 2 has an electrical connection portion 21. The valve assembly 100 includes a connecting joint 4. The connecting joint 4 is electrically connected to the circuit board 3. The connecting joint 4 includes a main body portion 41, an elastic portion 42, and a contact portion 43. The main body portion 41, the elastic portion 42, and the contact portion 43 are integrally arranged or the elastic portion 42 is connected to at least one of the main body portion 41 and the contact portion 43. There is an installation space 5 between the main body portion 41 and the contact portion 43. At least a portion of the installation space 5 is located between the main body portion 41 and the contact portion 43. At least a portion of the electrical connection portion 21 is located in the installation space 5. The electrical connection portion 21 is electrically connected to the main body portion 41 and / or the contact portion 43. The contact portion 43 and / or the main body portion 41 can be displaced at least along the width direction of the installation space 5 as the elastic portion 42 is elastically deformed.

[0034] In one embodiment, when the power connection portion 21 extends into the installation space 5, the power connection portion 21 contacts the contact portion 43 or the main body portion 41, and causes the contact portion 43 or the main body portion 41 to be displaced, so that the installation space 5 between the contact portion 43 and the main body portion 41 is adapted to the width of the power connection portion 21, and even if the thickness of the power connection portion 21 is greater than the original width of the installation space 5, the power connection portion 21 can still extend into the installation space 5, so that the power connection portion 21 and the connecting connector 4 are assembled.

[0035] The power connection portion 21 may cause the contact portion 43 to be displaced along the width direction of the installation space 5 , or may cause the body portion 41 to be displaced along the width direction of the installation space 5 , or the contact portion 43 and the body portion 41 may be displaced together.

[0036] In one embodiment, the original thickness of the installation space 5 is smaller than the width of the power connection portion 21 , so that after the power connection portion 21 extends into the installation space 5 , the contact portion 43 and the main body portion 41 tend to restore their original state, so that the power connection portion can be clamped by the contact portion 43 and the main body portion 41 , thereby increasing the installation firmness of the power connection portion 21 and the connecting connector 4 and the electrical connection stability.

[0037] In one embodiment, when the power connection part 21 deviates from the original position of the installation space 5, during the installation of the power connection part 21, the power connection part 21 contacts the contact part 43 or the main body 41, and causes one of them to be displaced. After the power connection part 21 is installed, the displaced contact part 43 or the main body 41 has a tendency to restore its original state under the action of the elastic part 42, so that it is tightly against the power connection part 21, making the electrical connection with the power connection part more stable.

[0038] In one embodiment, at least one of the contact portion 43 and the body portion 41 can be made of a material that has both electrical conductivity and reversible deformation capability, such as a copper sheet, an iron sheet, or an alloy. The electrical connection between the electrical connection portion 21 and at least one of the contact portion 43 and the body portion 41 can be achieved by contacting and connecting the electrical connection portion 21 with the connection connector 4, thereby achieving electrical connection between the valve component and the circuit board 3.

[0039] In another embodiment, the contact portion 43 and the main body portion 41 are made of a material that has no deformation ability or a weak deformation ability. In this case, a component with reversible deformation such as a spring can be connected to the back of at least one of the contact portion 43 and the main body portion 41, so that the contact portion 43 or the main body portion 41 is displaced to match the power connection portion 21; in this case, the spring is connected to at least one of the contact portion 43 and the main body portion 41 as an elastic portion 42. When the power connection portion 21 squeezes the contact portion 43 and / or the main body portion 41, the spring can be deformed, and then the contact portion 43 and / or the main body portion 41 can be displaced, so that the installation space 5 changes to adapt to the installation and matching of the power connection portion 21.

[0040] In one embodiment, the main body 41, the elastic part 42, and the contact part 43 are integrally formed. For example, they can be integrally formed with an elastic thin copper plate or other conductive metal materials such as iron, silver, or titanium, or they can be integrally formed with elastic nickel-titanium alloy or nickel-iron alloy and other conductive elastic alloys. The main body 41, the elastic part 42, and the contact part 43 can be formed by stamping and bending, or by mold injection. The main body 41, the elastic part 42, and the contact part 43 are three parts of the integral part, and the elastic part 42 is located between the main body 41 and the contact part 43.

[0041] In another embodiment, the main body 41, the elastic part 42, and the contact part 43 are separate parts, and the elastic part 42 connects the main body 41 and the contact part 43, which can be connected by welding or screw connection. Of course, in some embodiments, the main body 41 and the elastic part 42 are integrally formed and then connected to the contact part 43, or the elastic part 42 and the contact part 43 are integrally formed and then connected to the main body 41, or the elastic part 42 is connected to one of the main body 41 or the contact part 43.

[0042] In one embodiment, the stator and rotor of the valve component 2, and the power connection part 21 are integrated or connected with the stator. When the circuit board 3 energizes the stator through the connection joint 4, the stator generates a magnetic field, and the rotor rotates under the action of the magnetic field, thereby enabling the valve to be opened or closed, thereby achieving the control of the fluid flow. The present invention aims to solve the installation matching error between the power connection part 21 and the connection joint 4, and therefore, the technical means for the stator and the rotor to open or close the valve are not described in detail.

[0043] In one embodiment, the elastic portion 42 includes a first connecting segment 421 and a second connecting segment 422 that are connected or integrally arranged, the first connecting segment 421 is integral or connected to the contact portion, and the second connecting segment 422 is integral or connected to the main body portion 41, and at least a portion of the first connecting segment 421 and / or the second connecting segment 422 can undergo elastic deformation along the width direction of the installation space 5.

[0044] The first connecting section 421 and the second connecting section 422 can be integrally provided or separately connected. The first connecting section 421 and the second connecting section 422 correspond to the contact portion 43 and the body portion 41 respectively, so as to achieve displacement of the contact portion 43 or the body portion 41 so that the installation space 5 can match the power connection portion 21.

[0045] In one embodiment, the elastic portion 42 includes a fixing section 423, and the fixing section 423 is integral with or connected to the first connecting section 421 and the second connecting section 422. When the fixing section 423, the first connecting section 421, and the second connecting section 422 are integral, both ends of the fixing section 423 have fixing members 424, and the connecting connector 4 is fixed to the circuit board 3 via the fixing section 44. At this time, although the fixing section 423, the first connecting section 421, and the second connecting section 422 have elastic deformation capabilities due to their integral arrangement, both ends of the fixing section 423 have fixing members 424 fixed to the circuit board 3, and therefore, the fixing section 423 does not actually undergo significant deformation, such as Fig.13 Of course, the fixing member 424 can also be connected to both ends of the fixing section 423.

[0046] In another embodiment, the fixing member 424 may also cover the fixing section 423. In this case, the first connecting section 421 and the second connecting section 422 are respectively located at two end sides of the fixing member 424. Fig.14 shown.

[0047] In one embodiment, Figure 7 As shown, the main body 41 has a first plane portion 411, and the power connection portion 21 has a second plane portion 211 facing the first plane portion 411. The two surfaces of the first plane portion 411 and the second plane portion 211 that are oppositely arranged are parallel, and at least a portion of the first plane portion 411 is in contact with and electrically connected to at least a portion of the second plane portion 211.

[0048] Furthermore, the first plane portion 411 is parallel to and in contact with the second plane portion 211, that is, the main body portion 41 and the power connection portion 21 are in at least surface contact. Compared with point contact connection or line contact connection, the arrangement of the first plane portion 411 and the second plane portion 211 ensures sufficient contact area between the main body portion 41 and the power connection portion 21, so that the main body portion 41 and the power connection portion 21 have a larger current electrical connection capability.

[0049] In one embodiment, Figure 7 As shown, the contact portion 43 has a third plane portion 431, and the power connection portion 21 has a fourth plane portion 212 facing the third plane portion 431. The two oppositely disposed surfaces of the third plane portion 431 and the fourth plane portion 212 are parallel, and at least a portion of the third plane portion 411 is in contact with and electrically connected to at least a portion of the fourth plane portion 212.

[0050] Furthermore, the third plane portion 431 is in contact with the fourth plane portion 212 , that is, the contact portion 43 and the power connection portion 21 are in at least surface contact, ensuring sufficient contact area between the contact portion 43 and the power connection portion 21 , so that the contact portion 43 and the power connection portion 21 have a relatively large current electrical connection capability.

[0051] In one embodiment, the power connection portion 21 includes a plug, and the second plane portion 211 and the fourth plane portion 212 are located on both sides of the plug. When the power connection portion 21 does not extend into the installation space 5, the distance between the first plane portion 411 of the body portion 41 and the third plane portion 431 of the contact portion 43 is not greater than the thickness of the power connection portion 21. The plug is made of a material with deformation and conductivity such as a copper sheet. During the installation of the plug and the connection connector 4, the body portion 41 or the contact portion 43 may be displaced, or the plug may be displaced or deformed.

[0052] When the distance between the first plane portion 411 of the main body portion 41 and the third plane portion 431 of the contact portion 43 is smaller than the thickness of the power connection portion 21, the elastic portion 42 will be deformed when the power connection portion 21 extends into the installation space 5, thereby matching the installation space 5 with the power connection portion 21. At this time, the first plane portion 411 is in elastic contact with the second plane portion 211, and the third plane portion 431 is in elastic contact with the fourth plane portion 212. At this time, the power connection portion 21 is also subjected to the clamping force of the connecting connector 4, and is not easy to be separated from the connecting connector 4.

[0053] When the distance between the first plane portion 411 of the body portion 41 and the third plane portion 431 of the contact portion 43 is just equal to the thickness of the power connection portion 21, when the power connection portion 21 is aligned with the installation space 5 and can just extend into the installation space 5, the elastic portion 42 does not undergo elastic deformation, at which time the first plane portion 411 just contacts the second plane portion 211, and the third plane portion 431 just contacts the fourth plane portion 212. When the power connection portion 21 is not aligned with the installation space 5, and the power connection portion 21 is offset along its own thickness direction, the extension of the power connection portion 21 into the installation space 5 still causes the elastic portion 42 to undergo elastic deformation, and the body portion 41 or the contact portion 43 is offset through the elastic portion 42, so that the power connection portion 21 can extend into the installation space 5, and at this time the power connection portion 21 is in elastic contact with one of the body portion 41 or the contact portion 43, and has a distance therefrom.

[0054] In one embodiment, there are two elastic parts 42, which are respectively located on both sides of the main body 41, and each elastic part 42 is connected to a contact part 43. The two elastic parts 42 and the contact part 43 form two claw-like structures, which can firmly lock or limit the power connection part 21 within the installation space 5 to prevent the power connection part 21 from tilting or leaving the installation space 5. Of course, in other embodiments, the number of elastic parts 42 can also be 1 or 3 or more.

[0055] In one embodiment, the cross section of the elastic portion 42 is in the shape of an arc as a whole, and there is a gap between the end of the power connection portion 21 and the inner wall of the elastic portion 42. At least part of the arc-shaped elastic portion 42 can be elastically deformed along the width direction of the installation space 5, so that the contact portion 43 and / or the main body portion 41 can be displaced along the width direction of the installation space 5. The elastic portion 42, which has an arc-shaped cross section as a whole, has a rebound force after deformation, and can firmly fasten or limit the power connection portion 21 within the installation space 5. The arcs of the two elastic portions 42 are arranged opposite to each other, and the installation space 5 is wrapped between the two arcs, so that the power connection portion 21 can be easily extended into the installation space 5 to avoid interference with the elastic portion 42. In other embodiments, the cross section of the elastic portion 42 is in the shape of a polygon with a notch as a whole, which can also achieve the functions of deformation and fastening or limiting the power connection portion 21.

[0056] There is a distance between the end of the power connection part 21 and the inner wall of the elastic part 42, that is, along the length direction of the power connection part 21, the power connection part 21 has a position deviation space, and the inner wall of the elastic part 42 has a position deviation restriction on the power connection part 21 in the length direction of the power connection part 21, so that the connecting joint 4 meets the installation condition of the power connection part 21 deviating from its own length direction. Furthermore, the projections of the two contact parts 43 on the plane where the power connection part 21 is located are both located within the space where the power connection part 21 is located, so that the two contact parts 43 can always play a role in tightening or limiting the power connection part 21 at the same time, thereby increasing the connection stability between the power connection part 21 and the connecting joint 4. Figure 6 shown.

[0057] In one embodiment, the connection joint 4 includes an inclined portion 46, which is provided at one end of the body portion 41 away from the circuit board 3, and the inclined portion 46 is inclined in a direction away from the body portion 41. Specifically, one end of the body portion 41 is connected to the circuit board 3, and the other end thereof is connected to the inclined portion 46, the inclined portion 46 is inclined outward, and the power connection portion 21 extends into the installation space 5 from the inclined portion 46. The inclined portion 46 guides the installation of the power connection portion 21, and can guide the power connection portion 21 that is deviated in position along the thickness direction of the power connection portion 21 so that it can smoothly extend into the installation space 5.

[0058] In one embodiment, the power connection portion 21 is a plug made of a conductive and elastic material such as a thin copper sheet or a thin iron sheet. When the power connection portion 21 extends into the installation space 5 along the inclined portion 46, the power connection portion 21 is deformed so as to be able to extend into the installation space 5; or the connecting joint 4 is more easily deformed than the power connection portion 21. When the power connection portion 21 extends into the installation space 5 along the inclined portion 46, the connecting joint 4 is deformed and makes the installation space 5 face the power connection portion 21, so that the power connection portion 21 can extend into the installation space 5.

[0059] In one embodiment, the elastic portion 42 has a guide section 45 at one end away from the circuit board 3. The guide section 45 is similar to the inclined portion 46 and serves as an installation guide for the connecting portion 21. Furthermore, the guide section 45 and the inclined portion 46 are arranged opposite to each other, and the guide section 45 serves as a guide for the position deviation of the connecting portion 21 in another direction relative to the inclined portion 46. The guide section 45 and the inclined portion 46 meet the installation condition that the connecting portion 21 is offset in position along its own thickness direction.

[0060] In one embodiment, the circuit board 3 has a clearance hole 31, which is opposite to the installation space 5. The power connection part 21 can be inserted into the clearance hole 31. The clearance hole 31 allows the power connection part 21 to have an excessive installation margin in the vertical direction. After the power connection part 21 is inserted into the installation space 5, it can continue to extend upward into the clearance hole 31, thereby preventing the power connection part 21 from extending too long into the installation space 5 and causing damage such as collision or wear between the power connection part 21 and the circuit board 3.

[0061] Along the length direction of the power connection part 21, there is a distance between the end of the power connection part 21 and the inner wall of the elastic part 42, which meets the installation condition of the power connection part 21 with position deviation in its length direction; the setting of the guide section 45 and the inclined section meets the installation condition of the power connection part 21 with position deviation in its thickness direction; and the setting of the clearance hole 31 solves the problem caused by the installation position deviation of the power connection part 21 in its installation height direction.

[0062] In one embodiment, the valve assembly 100 includes at least two valve components 2, each valve component 2 has one or at least two power connection parts 21, the valve assembly 100 includes at least two connecting joints 4, the connecting joints 4 correspond one-to-one to the power connection parts 21, the power connection parts 21 correspond one-to-one to the connecting joints 4, and the valve assembly includes a circuit board 3, and at least two connecting joints 4 are connected to the circuit board 3.

[0063] The valve assembly 100 can be applied to a thermal management system, wherein the thermal management system can be a vehicle thermal management system, such as a new energy vehicle thermal management system. The valve assembly 100 integrates at least two valve components 2, and the valve assembly 100 can drive the valve component 2 to move. The valve component 2 is connected to an external flow channel component, and the flow channel component has a flow channel. Under the control of the circuit board 3, the valve component 2 can realize the opening and closing of the flow channel. For example, when the circuit board 3 controls the valve component 2 to realize the connection of the flow channel, the valve component 2 can be directly connected or throttled to connect the flow channel. It can be understood that the direct connection does not change or tends not to change the pressure of the working fluid before and after flowing through the valve component 2, such as the pressure loss range is less than 1%, and the throttling connection means that the pressure of the working fluid before flowing through the valve component 2 is greater than the pressure after flowing through the valve component 2.

[0064] At least two valve components 2 are integrated into the box body 1, and any valve component 2 has one or at least two electrical connection parts 21, and the number of connecting joints 4 is at least two. When multiple connecting joints 4 are connected to the circuit board 3, there are installation errors in the connecting joints 4 at different positions. Especially when there are multiple connecting joints 4, each installation error easily makes it more difficult to connect the connecting joint 4 with the electrical connection part 21 of the valve component 2 perfectly. However, through the structure of the connecting joint 4 unique to the present application, the size of the installation space 5 is changed through the elastic part 42 to compensate for the installation error.

[0065] In one embodiment, the connection joint 4 has a plurality of fixing portions 44, the fixing portions 44 are fixedly connected to the circuit board 3, and the plurality of fixing portions 44 are evenly distributed at one end of the connection joint 4 facing the circuit board 3. The fixing portion 44 includes a connecting section 441 and a bending section 442, the connecting section 441 is connected to the main body 41 or the elastic portion 42, or the main body 41 and the elastic portion 42 are respectively connected with the connecting section 441, and the bending section 442 is connected to the circuit board 3 by soldering or the like, the bending section 442 faces the circuit board 3, the bending section 412 is close to or attached to the circuit board 3 and then fixedly connected by soldering or the like, and the bending section 442 increases the connection area between the fixing portion 44 and the circuit board 3, so that the connection joint 4 is firmly fixed to the circuit board 3. In one embodiment, the elastic portion 42 occupies most of the connecting joint 4, and the fixed portion 44 is evenly distributed at one end of the elastic portion 42 facing the circuit board 3. The connecting section 441 of the fixed portion 44 is connected to the elastic portion 42, and the bending section 442 of the fixed portion 44 is soldered to the circuit board 3. At this time, the fixed portion 44 is the same as the fixing part 424 of the fixed section 423.

[0066] In one embodiment, the main body 41 has a bending portion 412, which is located at one end of the first plane portion 411 close to the circuit board 3, and the bending portion 412 has the same height as the bending section 442. The bending portion 412 is close to or attached to the circuit board 3 and then fixedly connected by soldering or the like. The bending portion 412 and the bending section 442 together fix the connection connector 4 to the circuit board 3.

[0067] In another embodiment, the circuit board 3 is provided with a first opening 32 for the fixing portion 44 to extend into. In this case, the bending section 442 is not required, and the fixing portion 44 can be a straight rod structure. After the fixing portion 44 extends into the first opening 32 , it is fixed by soldering.

[0068] In one embodiment, the circuit board 3 is provided with a second opening 33 corresponding to the main body 41 , a portion of the main body 41 extends into the second opening 33 and is then fixed by soldering or the like, thereby connecting the connector 4 to the circuit board 3 .

[0069] Furthermore, the main body 41 has a protrusion 413, and the second opening 33 corresponds to the protrusion 413. At least a portion of the protrusion 413 extends into the second opening 33, and the width of the protrusion 413 extending into the second opening 33 is the same as the width of the fixing portion 44 extending into the first opening 32, thereby making the connecting connector 4 and the circuit board 3 firmly connected, and the force of the connection between the two is more balanced.

[0070] The connection connector 4 is fixed to the circuit board 3 by the fixing portion 44 or by the main body 41 . Either one or both methods can be used.

[0071] like Figure 1-Figure 16As shown, an embodiment also describes an assembly method of a valve assembly, wherein the valve assembly at least comprises a valve component 2 and two connecting joints 4, the valve component 2 at least comprises two electrical connection parts 21, the two electrical connection parts 21 are defined as a first electrical connection part 201 and a second electrical connection part 202, and the two connecting joints 4 are defined as a first connecting joint 401 and a second connecting joint 402;

[0072] When the first power connection portion 201 is inserted into the first installation space 501, the contact portion 43 and / or the body portion 41 of the first connection connector 401 can be displaced at least once along the width direction of the first installation space 501;

[0073] When the second power connection portion 202 is inserted into the second installation space 502, the contact portion 43 and / or the body portion 41 of the first connection connector 401 can at least be displaced twice along the width direction of the first installation space 501;

[0074] The primary displacement and the secondary displacement can be performed simultaneously or successively.

[0075] In the assembly method of the valve assembly of the above technical solution, the contact portion 43 and / or the main body portion 41 can undergo a single displacement to compensate for the installation deviation between the power connection portion 21 and the connecting joint 4 caused by the processing thickness deviation, and can also undergo a secondary displacement to further compensate for the installation deviation caused by the deviation in the distance between different power connection portions 21 and the distance between different connecting joints 4.

[0076] Specifically, the valve assembly has a circuit board, a circuit board 3 is connected to at least two connecting joints 4, and a valve component 2 has at least two power connection parts 21, and the power connection parts 21 correspond one-to-one to the connecting joints 4. When the valve component 2 is electrically connected to the circuit board 3, the one-to-one corresponding power connection parts 21 need to be connected to the connecting joints 4.

[0077] During the process of inserting the first power connection portion 201 into the first installation space 501, due to the processing error between the first power connection portion 201 and the first installation space 501, the first power connection portion 201 occupies the first installation space 501 and pushes the corresponding contact portion 43 and / or the body portion 41 so that the contact portion 43 and / or the body portion 41 is displaced relative to the first power connection portion 201 along the width direction of the first installation space 501, so that the first installation space 501 is changed and adapted to the first power connection portion 201.

[0078] Since there is a deviation between the distance between the second power connection portion 202 and the first power connection portion 201 and the distance between the first installation space 501 and the second installation space 502, the installation of different power connections and the installation spaces corresponding thereto will also produce installation deviations. Therefore, during the process of inserting the second power connection portion 202 into the second installation space 502, by moving the positions of the first power connection portion 201 and the second power connection portion 202 as a whole, the contact portion 43 and / or the body portion 41 corresponding to the first power connection portion 201 can be adjusted in real time to cause a secondary displacement, thereby enabling the first power connection portion 201 and the second power connection portion 202 to be inserted into the first installation space 501 and the second installation space 502, respectively, thereby compensating for the distance deviation between the multiple power connection portions 21 and the distance between the multiple installation spaces 5.

[0079] Furthermore, the contact portion 43 and / or the main body portion 41 of the first connecting joint 401 can be displaced at least along the width direction of the installation space 5 as the elastic portion 42 of the first connecting joint 401 is elastically deformed, and the elastic portion 42 is connected to at least one of the main body portion 41 and the contact portion 43, or the main body portion 41, the elastic portion 42, and the contact portion 43 are integrally arranged.

[0080] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and inventive concept of the present invention by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
