Description

Technical Field

[0001] This application belongs to the field of vehicle lighting technology, and particularly relates to an electrical connection structure, vehicle lighting, and vehicle. Background Technology

[0002] In vehicle lighting systems, light sources emit light through optical components to achieve functions such as illumination, signaling, and ambient lighting. The light source is typically mounted on a circuit board and electrically connected to the lighting harness via connectors on the circuit board. Currently, the most common solution involves placing board-side connectors on the circuit board and connecting wire-side connectors to the lighting harness. The wire-side connectors are inserted into the board-side connectors, causing the terminals inside the wire-side connectors to make contact with the pins of the board-side connectors, thus achieving electrical connection. However, this method requires separate connectors on both the circuit board and the lighting harness, resulting in higher product costs. Utility Model Content

[0012] Optionally, the terminal portion is made of a conductive material; the terminal portion contacts the battery core of the wire harness, and the terminal portion contacts the board end terminal in the mounting groove.

[0013] Optionally, the board-end electrical connection portion is exposed copper arranged on the circuit board, and the terminal portion and / or the battery cell of the wire harness passes through the second opening and contacts the exposed copper.

[0014] Optionally, the terminal portion is made of a conductive material; an elastic contact piece is formed in the terminal portion, the elastic contact piece contacts the exposed copper and the elastic contact piece is pressed tightly against the exposed copper by its own elasticity.

Detailed Implementation

[0053] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0054] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0055] This application provides an electrical connection structure for vehicle lighting, comprising a wire-end plug-in portion 8 integrally formed with an optical component, a board-end electrical connection portion disposed on a circuit board 4, and a wire harness 7. The wire-end plug-in portion 8 includes a through mounting groove 9, which includes a first opening 10 and a second opening 11 facing away from each other. The relative position of the circuit board 4 and the optical component is fixed, and the second opening 11 of the board-end electrical connection portion and the wire-end plug-in portion 8 are correspondingly arranged. The wire harness 7 includes a battery cell 13 and a terminal portion 14 disposed at one end of the battery cell 13. The terminal portion 14 is connected to the first opening 10 of the mounting groove 9, and the battery cell 13 is directly or indirectly electrically connected to the board-end electrical connection portion. Because the relative position of the circuit board 4 and the optical component is fixed, and the second opening 11 of the board-end electrical connection portion and the wire-end plug-in portion 8 are correspondingly arranged, when the terminal portion 14 in the wire harness 7 is connected to the first opening 10 of the mounting groove 9 in the wire-end plug-in portion 8, the battery cell 13 of the wire harness 7 can be directly or indirectly electrically connected to the board-end electrical connection portion. Therefore, in the electrical connection structure provided by this application, the wire end connector 8 is integrally formed with the optical component, eliminating the need for an additional separate wire end connector 6 (such as...). Figure 1 As shown in the figure, this reduces product costs.

[0056] Wherein, the direct electrical connection between the battery cell 13 of the wire harness 7 and the board end electrical connection part means that the battery cell 13 in the wire harness 7 directly contacts the conductive part in the board end electrical connection part, thereby achieving electrical connection; the indirect electrical connection between the battery cell 13 of the wire harness 7 and the board end electrical connection part means that the wire harness 7 contacts another conductive component, which in turn contacts the conductive part in the board end electrical connection part, thereby achieving electrical connection.

[0057] This application also provides a vehicle lighting fixture, which includes an optical component, a circuit board 4, and the aforementioned electrical connection structure. The optical component may include an optical part and a mounting part 3, with a wire terminal connector 8 integrally formed with the optical part or the mounting part 3. The optical part may be a reflector 1 or a condenser 2. Therefore, in the vehicle lighting fixture provided by this application, the wire terminal connector 8 is integrally formed with the optical component, eliminating the need for a separate wire terminal connector 6 (such as...). Figure 1 As shown in the figure, this reduces product costs.

[0058] This application also provides a vehicle including the aforementioned vehicle lighting fixture. Therefore, in the vehicle provided by this application, the wire connector 8 is integrally formed with the optical component, eliminating the need for a separate wire connector 6 (such as...). Figure 1 As shown in the figure, this reduces product costs.

[0059] Based on the above-described electrical connection structure, vehicle lights, and vehicle, this application will be described below with reference to different specific embodiments.

[0060] Example 1

[0061] See Figures 2 to 8 The electrical connection structure provided in this embodiment includes a wire-end plug-in portion 8 integrally formed with the optical component, a board-end electrical connection portion disposed on the circuit board 4, and a wire harness 7. The wire-end plug-in portion 8 includes a mounting groove 9 extending along the plug-in direction, and the mounting groove 9 includes a first opening 10 and a second opening 11 facing away from each other. The relative position of the circuit board 4 and the optical component is fixed, and the second opening 11 of the board-end electrical connection portion and the wire-end plug-in portion 8 are correspondingly disposed. The wire harness 7 includes a battery cell 13 and a terminal portion 14 disposed at one end of the battery cell 13. The terminal portion 14 is connected to the first opening 10 of the mounting groove 9, and the battery cell 13 is directly or indirectly electrically connected to the board-end electrical connection portion.

[0062] In some specific implementations of this embodiment, the terminal portion 14 may include an extension portion 15 extending from the housing of the terminal portion 14. The end of the extension portion 15 away from the housing is a free end. The wire end insertion portion 8 includes a slot 16, and the extension portion 15 is engaged with the slot 16. That is, the extension portion 15 can be a barbed structure, and the slot 16 can be a corresponding barbed limiting groove. When the terminal portion 14 is inserted into the mounting groove 9 from the first opening 10, the end of the extension portion 15 away from the housing is a free end, so the extension portion 15 can undergo elastic deformation. When the end of the extension portion 15 away from the housing reaches the position of the slot 16 (i.e., when the barbed structure enters the barbed limiting groove), the free end of the extension portion 15 returns to its original position, thereby engaging the extension portion 15 with the slot 16 (see [reference]). Figure 7 This prevents the terminal portion 14 from exiting the mounting slot 9, thus fixing the terminal portion 14 to the mounting slot 9.

[0063] In some specific implementations of this embodiment, the board-end electrical connection part can be a board-end connector 12 mounted on the circuit board 4. The board-end connector 12 has a board-end interface 17 and a board-end terminal 18 located in the board-end interface 17. The second opening 11 is inserted into the board-end interface 17, and the board-end terminal 18 is directly or indirectly electrically connected to the battery cell 13 of the wire harness 7 in the mounting groove 9.

[0064] Specifically, the terminal portion 14 can be made entirely of a conductive material. The terminal portion 14 contacts the battery cell 13 of the wire harness 7 and contacts the board-end terminal 18 in the mounting groove 9, thereby allowing the battery cell 13 in the wire harness 7 to be electrically connected to the board-end terminal 18 through the terminal portion 14.

[0065] In practical implementation, the number of wire harnesses 7 is generally multiple. These multiple wire harnesses 7 can be connected in a ribbon cable at one end of the terminal section 14 to prevent incorrect installation of each wire harness 7. Multiple mounting slots 9 are arranged side-by-side on the wire terminal connector 8, each corresponding to one of the multiple wire harnesses 7. The board-end connector 12 has multiple board-end interfaces 17, each containing a board-end terminal 18. These multiple board-end interfaces 17 correspond one-to-one with the multiple mounting slots 9.

[0066] This embodiment also provides a vehicle lighting fixture, including the aforementioned electrical connection structure, circuit board 4, and optical components. The optical components may include an optical section and a mounting section 3, with the wire-end connector 8 integrally formed with the optical section or the mounting section 3. The optical section and the mounting section 3 may be integrally formed or independent of each other. In this embodiment, the optical section may be a reflector 1, which is integrally formed with the mounting section 3; however, this application is not intended to limit the scope of the invention.

[0067] In some specific implementations of this embodiment, the vehicle lighting fixture may further include a radiator 5. The circuit board 4 can be mounted on the radiator 5. The relative positions between the radiator 5 and the mounting portion 3 are fixed. The positioning method between the radiator 5 and the mounting portion 3 is not limited; for example, it can be positioned by providing corresponding positioning surfaces on the radiator 5 and the mounting portion 3 respectively, or by providing corresponding positioning pins and positioning pin holes on the radiator 5 and the mounting portion 3 respectively, etc. The fixing method between the radiator 5 and the mounting portion 3 is also not limited; for example, it can be fixed by threaded fasteners or welding, etc.

[0068] During installation, the terminal portions 14 on the multiple wire harnesses 7 are sequentially inserted into the corresponding mounting slots 9 on the wire end plug-in portion 8, which is integrally formed with the optical component. The extension portion 15 in the terminal portion 14 engages with the slot 16, thereby fixing the terminal portion 14 in the mounting slot 9 of the wire end plug-in portion 8. Then, the optical component is installed with the circuit board 4, heat sink 5, and other parts. The second opening 11 of the mounting slot 9 on the mounting part 3 can be first inserted into the board end plug-in interface 17 on the circuit board 4. The terminal portion 14 in the mounting slot 9 contacts the board end terminal 18 in the board end plug-in interface 17 to achieve electrical connection. Then, the mounting part 3 and the circuit board 4 are fixed.

[0069] In this embodiment, the wire connector 8 is integrated onto the optical component (i.e., the wire connector 8 and the optical component are integrally formed), eliminating the need to fabricate a separate wire connector 6 (such as...). Figure 1 (As shown in the diagram), which reduces costs. Moreover, the multiple wire harnesses 7 use ribbon cables at one end of the terminal section 14, which can prevent incorrect assembly of each wire harness 7 without adding parts.

[0070] Example 2

[0071] See Figures 9 to 12 and cooperate Figures 4 to 6 as well as Figure 8 The electrical connection structure of this embodiment is basically the same as that of Embodiment 1; the difference from Embodiment 1 is that the optical component of the optical assembly in this embodiment is a condenser 2. This application is not intended to limit this, and other optical components besides the reflector 1 and the condenser 2 are also within the scope of protection of this application.

[0072] Example 3

[0073] See Figures 13 to 19 The electrical connection structure provided in this embodiment includes a wire-end plug-in portion 8 integrally formed with the optical component, a board-end electrical connection portion disposed on the circuit board 4, and a wire harness 7. The wire-end plug-in portion 8 includes a mounting groove 9 extending along the plug-in direction, and the mounting groove 9 includes a first opening 10 and a second opening 11 facing away from each other. The relative position of the circuit board 4 and the optical component is fixed, and the second opening 11 of the board-end electrical connection portion and the wire-end plug-in portion 8 are correspondingly disposed. The wire harness 7 includes a battery cell 13 and a terminal portion 14 disposed at one end of the battery cell 13. The terminal portion 14 is connected to the first opening 10 of the mounting groove 9, and the battery cell 13 is directly or indirectly electrically connected to the board-end electrical connection portion.

[0074] In some specific implementations of this embodiment, the terminal portion 14 may include an extension portion 15 extending from the housing of the terminal portion 14. The end of the extension portion 15 away from the housing is a free end. The wire end insertion portion 8 includes a slot 16, and the extension portion 15 is engaged with the slot 16. That is, the extension portion 15 can be a barbed structure, and the slot 16 can be a corresponding barbed limiting groove. When the terminal portion 14 is inserted into the mounting groove 9 from the first opening 10, the end of the extension portion 15 away from the housing is a free end, so the extension portion 15 can undergo elastic deformation. When the end of the extension portion 15 away from the housing reaches the position of the slot 16 (i.e., when the barbed structure enters the barbed limiting groove), the free end of the extension portion 15 returns to its original position, thereby engaging the extension portion 15 with the slot 16 (see [reference]). Figure 19 This prevents the terminal portion 14 from exiting the mounting slot 9, thus fixing the terminal portion 14 to the mounting slot 9.

[0075] In some specific implementations of this embodiment, the board-end electrical connection portion can be exposed copper 19 arranged on the circuit board 4 for contact conduction (e.g., Figure 16 As shown), the exposed copper 19 can be a trace layer. The terminal portion 14 passes through the second opening 11 and contacts the exposed copper 19. Specifically, the terminal portion 14 can be made entirely of a conductive material, and an elastic contact piece 20 is formed in the terminal portion 14. The elastic contact piece 20 contacts the exposed copper 19 and uses its own elasticity to press against the exposed copper 19, thereby enabling the exposed copper 19 to maintain a reliable electrical connection with the terminal portion 14 (specifically the elastic contact piece 20).

[0076] In practical implementation, the number of wire harnesses 7 is generally multiple. These multiple wire harnesses 7 can be connected in a ribbon cable at one end of the terminal section 14 to prevent incorrect installation of each wire harness 7. Multiple mounting slots 9 are arranged side-by-side on the wire terminal connector 8, each corresponding to one of the multiple wire harnesses 7. Multiple exposed copper 19s are provided on the circuit board 4, and their arrangement and spacing correspond one-to-one with the mounting slots 9 on the wire terminal connector 8.

[0077] This embodiment also provides a vehicle lighting fixture, including the aforementioned electrical connection structure, circuit board 4, and optical components. The optical components may include an optical section and a mounting section 3, with the wire-end connector 8 integrally formed with the optical section or the mounting section 3. The optical section and the mounting section 3 may be integrally formed or independent of each other. In this embodiment, the optical section may be a reflector 1, which is integrally formed with the mounting section 3; however, this application is not intended to limit the scope of the invention.

[0078] In some specific implementations of this embodiment, the vehicle lighting fixture may further include a radiator 5. The circuit board 4 can be mounted on the radiator 5. The relative positions between the radiator 5 and the mounting portion 3 are fixed. The positioning method between the radiator 5 and the mounting portion 3 is not limited; for example, it can be positioned by providing corresponding positioning surfaces on the radiator 5 and the mounting portion 3 respectively, or by providing corresponding positioning pins and positioning pin holes on the radiator 5 and the mounting portion 3 respectively, etc. The fixing method between the radiator 5 and the mounting portion 3 is also not limited; for example, it can be fixed by threaded fasteners or welding, etc.

[0079] During installation, the terminal portions 14 on the multiple wire harnesses 7 are sequentially inserted into the corresponding mounting slots 9 on the wire end plug-in portion 8, which is integrally formed with the optical components. The extension portion 15 in the terminal portion 14 engages with the slot 16 to fix the terminal portion 14 in the mounting slot 9 of the wire end plug-in portion 8. Then, the wire end plug-in portion 8 is installed with components such as the circuit board 4 and the heat sink 5. The terminal portion 14 in the mounting slot 9 on the wire end plug-in portion 8 abuts against the corresponding exposed copper 19 on the circuit board 4 to achieve electrical connection. The elastic contact piece 20 formed in the terminal portion 14 can ensure that it always has reliable contact with the exposed copper 19 on the circuit board 4.

[0080] In this embodiment, the wire connector 8 is integrated onto the optical component (i.e., the wire connector 8 and the optical component are integrally formed), eliminating the need to fabricate a separate wire connector 6 (such as...). Figure 1 As shown in the diagram, this reduces costs. Furthermore, by using several exposed copper contacts 19 on the circuit board 4 instead of board-end connectors 12, the cost of board-end connectors 12 is saved, further reducing costs. The design of forming elastic contact pieces 20 in the terminal portion 14 of the wire harness 7 ensures reliable contact between the terminal portion 14 (specifically, the elastic contact pieces 20 formed in the terminal portion 14) and the exposed copper contacts 19 on the circuit board 4, forming a reliable electrical connection. In this embodiment, multiple wire harnesses 7 use ribbon cables at one end of the terminal portion 14, enabling mis-assembly prevention for each wire harness 7 without adding components.

[0081] Example 4

[0082] See Figures 20 to 24 and cooperate Figure 17 and Figure 18 The electrical connection structure of this embodiment is basically the same as that of embodiment 3; the difference from embodiment 3 is that the optical component of the optical assembly in this embodiment is a condenser 2. This application is not intended to limit this application, and other optical components besides the reflector 1 and the condenser 2 are also within the scope of protection of this application.

[0083] Example 5

[0084] See Figures 25 to 30 and cooperate Figure 16 The electrical connection structure provided in this embodiment includes a wire-end plug-in portion 8 integrally formed with the optical component, a board-end electrical connection portion disposed on the circuit board 4, and a wire harness 7. The wire-end plug-in portion 8 includes a mounting groove 9 extending along the plug-in direction, and the mounting groove 9 includes a first opening 10 and a second opening 11 facing away from each other. The relative position of the circuit board 4 and the optical component is fixed, and the second opening 11 of the board-end electrical connection portion and the wire-end plug-in portion 8 are correspondingly disposed. The wire harness 7 includes a battery cell 13 and a terminal portion 14 disposed at one end of the battery cell 13. The terminal portion 14 is connected to the first opening 10 of the mounting groove 9, and the battery cell 13 is directly or indirectly electrically connected to the board-end electrical connection portion.

[0085] In some specific implementations of this embodiment, the terminal portion 14 may include an extension portion 15 extending from the housing of the terminal portion 14. The end of the extension portion 15 away from the housing is a free end. The wire end insertion portion 8 includes a slot 16, and the extension portion 15 is engaged with the slot 16. That is, the extension portion 15 can be a barbed structure, and the slot 16 can be a corresponding barbed limiting groove. When the terminal portion 14 is inserted into the mounting groove 9 from the first opening 10, since the end of the extension portion 15 away from the housing is a free end, the extension portion 15 can undergo elastic deformation. When the end of the extension portion 15 away from the housing reaches the position of the slot 16 (i.e., when the barbed structure enters the barbed limiting groove), the free end of the extension portion 15 returns to its original position, thereby engaging the extension portion 15 with the slot 16 (see [reference]). Figure 30 This prevents the terminal portion 14 from exiting the mounting slot 9, thus fixing the terminal portion 14 to the mounting slot 9.

[0086] In some specific implementations of this embodiment, the number of wire harnesses 7 is generally multiple, and each wire harness 7 has a corresponding terminal portion 14. Preferably, the terminal portions 14 of the multiple wire harnesses 7 can be integrally formed and arranged in a row, so that the multiple wire harnesses 7 can be arranged in sequence, thereby achieving the prevention of incorrect assembly of each wire harness 7. Specifically, the housing of the terminal portion 14 may include a retaining portion 21 and a mounting portion 22, the mounting portion 22 and the retaining portion 21 are interconnected and integrally formed (see...). Figures 27 to 29 The encapsulation portion 21 wraps around the rubber insulation layer outside the corresponding battery cell 13, and the encapsulation portion 21 tightly wraps and presses the rubber insulation layer outside the corresponding battery cell 13, thus achieving a fixed connection between the encapsulation portion 21 and the battery cell 13, that is, achieving a fixed connection between the terminal portion 14 and the battery cell 13. In some specific implementations of this embodiment, the mounting portions 22 in the multiple terminal portions 14 are interconnected and integrally formed, and the encapsulation portions 21 in the multiple terminal portions 14 are independent.

[0087] In some specific implementations of this embodiment, the mounting portion 22 extends with the aforementioned extension portion 15. The mounting portion 22 can be fixed within the mounting groove 9 by the snap-fit ​​connection between the extension portion 15 and the slot 16, thus achieving a fixed connection between the terminal portion 14 and the mounting groove 9. The terminal portion 14 can be made of a conductive material or an insulating material; when the terminal portion 14 is made of a conductive material, it does not contact the battery cell 13.

[0088] In some specific implementations of this embodiment, the wire connector 8 includes a mounting groove 9 and multiple slots 16. The shape of the mounting portion 22 in the integrally formed multiple terminal portions 14 is adapted to the shape of the mounting groove 9. The integrally formed multiple terminal portions 14 extend into the mounting groove 9 from the first opening 10 (the wrapping portion 21 enters the mounting groove 9 first, and the mounting portion 22 enters the mounting groove 9 later) and are installed in the mounting groove 9. The multiple slots 16 correspond one-to-one with the multiple terminal portions 14, and the extension portion 15 on each terminal portion 14 is respectively engaged with the corresponding slot 16, thereby realizing the fixed installation of the integrally formed multiple terminal portions 14 in the mounting groove 9.

[0089] The board-end electrical connection portion can be exposed copper 19 arranged on the circuit board 4 for contact and conduction, and the exposed copper 19 is a trace layer. After multiple integrally manufactured terminal portions 14 are fixedly installed in the mounting slot 9, the battery cell 13 in the wire harness 7 extends out of the terminal portion 14 and passes through the second opening 11 to contact the exposed copper 19, thereby realizing the electrical connection between the battery cell 13 and the exposed copper 19. Multiple exposed copper 19s can be provided on the circuit board 4, and multiple exposed copper 19s correspond one-to-one with multiple wire harnesses 7.

[0090] This embodiment also provides a vehicle lighting fixture, including the aforementioned electrical connection structure, circuit board 4, and optical components. The optical components may include an optical section and a mounting section 3, with the wire-end connector 8 integrally formed with the optical section or the mounting section 3. The optical section and the mounting section 3 may be integrally formed or independent of each other. In this embodiment, the optical section may be a reflector 1, which is integrally formed with the mounting section 3; however, this application is not intended to limit the scope of the invention.

[0091] In some specific implementations of this embodiment, the vehicle lighting fixture may further include a radiator 5. The circuit board 4 can be mounted on the radiator 5. The relative positions between the radiator 5 and the mounting portion 3 are fixed. The positioning method between the radiator 5 and the mounting portion 3 is not limited; for example, it can be positioned by providing corresponding positioning surfaces on the radiator 5 and the mounting portion 3 respectively, or by providing corresponding positioning pins and positioning pin holes on the radiator 5 and the mounting portion 3 respectively, etc. The fixing method between the radiator 5 and the mounting portion 3 is also not limited; for example, it can be fixed by threaded fasteners or welding, etc.

[0092] During installation, the multiple terminal parts 14, which are integrally formed, are inserted into the corresponding mounting slots 9 on the wire end plug part 8, which is integrally formed with the optical component; then the wire end plug part 8 is installed with the circuit board 4, heat sink 5 and other parts.

[0093] In this embodiment, the wire connector 8 is integrated onto the optical component (i.e., the wire connector 8 and the optical component are integrally formed), eliminating the need to fabricate a separate wire connector 6 (such as...). Figure 1 (As shown in the diagram), which reduces costs. Furthermore, the structure of the terminal portion 14 in this embodiment reduces material and manufacturing costs compared to the aforementioned terminal portion 14 structure, further reducing costs. The use of several exposed copper 19s for contact conduction on the circuit board 4 instead of the board-end connectors 12 saves on the cost of the board-end connectors 12, thereby further reducing costs. Moreover, the battery cell 13 in the wire harness 7 protrudes from the terminal portion 14 and abuts against the corresponding exposed copper 19 on the circuit board 4 to achieve electrical connection. The contact area between the battery cell 13 and the exposed copper 19 is larger than the line contact area between the terminal portion 14 and the board-end terminal 18 in Embodiment 1, resulting in lower contact thermal resistance and lower heat loss.

[0094] Example 6

[0095] See Figures 31 to 34 and cooperate Figures 27 to 29 as well as Figure 23 The electrical connection structure of this embodiment is basically the same as that of embodiment 5; the difference from embodiment 5 is that the optical component of the optical assembly in this embodiment is a condenser 2. This application is not intended to limit this application, and other optical components besides the reflector 1 and the condenser 2 are also within the scope of protection of this application.

[0096] Furthermore, this application also provides a vehicle that includes the vehicle lighting fixtures provided in any of the foregoing embodiments. Therefore, in the vehicle provided by this application, the wire terminal connector 8 is integrally formed with the optical component, eliminating the need for a separate wire terminal connector 6 (such as...). Figure 1 As shown in the figure, this reduces product costs.

[0097] The above is merely an illustrative description of several embodiments provided in this application. Features in each embodiment may be omitted or added, and features in multiple embodiments may be combined or substituted with each other. All of the above variations are within the protection scope of this application.

[0098] The embodiments of this application have been described in detail above with reference to the accompanying drawings, but this application is not limited to the above embodiments. Even if various changes are made to this application, if these changes fall within the scope of the claims of this application and their equivalents, they shall still fall within the protection scope of this application.
