Abstract
Description
Technical Field
[0001] This application relates to the field of automotive technology, and in particular to a wiring connection structure and a vehicle. Background Technology
[0002] With the rapid development of new energy electrification and intelligentization, flexible flat cables (FFC) are often used in automotive wiring to make electrical connections between various electronic devices.
[0003] To enable electrical connections between two or more electronic devices, an FFC (Flexible Connection Control) is implemented using a branching mechanism. For example, an FFC consists of a main trunk and two branch lines, both of which are electrically connected to the main trunk. This allows for electrical connections between the electronic devices on the main trunk and the electronic devices on the two branch lines.
[0004] Currently, the connection between two cables (such as a main line and a branch line) is generally achieved through a cable connector. This connector is typically attached to one end of one cable, while the other end of the cable is directly connected to the connector, thus establishing an electrical connection between the two cables. However, this connection method is relatively complex, unsuitable for some environments (such as a vehicle environment), and costly. Utility Model Content
[0005] This application provides a wiring connection structure and a vehicle. In this wiring connection structure, the first and second wirings are connected by a crimping plate that passes through and presses them together. This connection method is simple and low-cost. Furthermore, the crimping plate is small in size, making it suitable for a wider range of working environments.
[0006] In a first aspect, this application provides a ribbon cable connection structure, including a first insulating layer and a second insulating layer, and a conductor layer disposed between the first insulating layer and the second insulating layer; wherein, the first end of the first ribbon cable overlaps with the first end of the second ribbon cable, and the conductor layer of the first ribbon cable at the overlapping position is in direct contact with the conductor layer of the first ribbon cable; a crimping piece penetrates through the conductor layer in direct contact between the first ribbon cable and the second ribbon cable, and presses the conductor layer in direct contact between the first ribbon cable and the second ribbon cable.
[0007] In this structure, the first and second ribbon cables are connected by a crimping tab that passes through and presses them together, eliminating the need for additional ribbon cable connectors. Because the crimping tab is simple in structure and low in cost, this connection method is straightforward, resulting in a lower overall cost and applicability to a wider range of working environments. Furthermore, the crimping tab passes through both the first and second ribbon cables, preventing them from easily shifting and ensuring a stable connection.
[0008] In addition, the conductor layers at the overlapping positions of the first and second rows of wires are in direct contact, which allows for direct conductivity through the conductor layers, thereby ensuring the conductivity stability between the first and second rows of wires.
[0009] One possible design is that both the first and second ribbon cables are formed using a hot-pressing process. Since this process is relatively mature, this design can guarantee the quality of both the first and second ribbon cables.
[0010] One possible design is that the conductor layer at the first end of the first ribbon cable does not have a first insulating layer and / or a second insulating layer, and the conductor layer at the first end of the second ribbon cable also does not have a first insulating layer and / or a second insulating layer. This design allows direct contact between the conductor layers of the first and second ribbon cables at their overlapping positions.
[0011] One possible design is that the crimping tab is made of a conductive material. This design allows the first and second rows of wires to conduct electricity through the crimping tab, further ensuring the conductivity stability between the first and second rows of wires.
[0012] One possible design is that the crimping sheet includes a pressure plate and crimping wings arranged perpendicularly to the pressure plate; wherein the crimping wings bend and tighten after penetrating the conductor layer in direct contact between the first and second rows of wires, and together with the pressure plate, press the conductor layer in direct contact between the first and second rows of wires.
[0013] One possible design is that the crimping wing is located on the same surface of the pressure plate.
[0014] One possible design is that the number of crimping wings is at least two, and the at least two crimping wings are arranged opposite each other on both sides of the same surface of the pressure plate.
[0015] One possible design is that the press sheet is a one-piece molded structure.
[0016] One possible design also includes a first connector and a second connector, with the second end of the first ribbon cable connected to the first connector and the second end of the second ribbon cable connected to the second connector. It is understood that the first and second connectors are used for connection to an electronic device.
[0017] Secondly, this application also provides a vehicle comprising at least two electronic devices and the wiring connection structure described in the first aspect above; wherein the wiring connection structure is connected between the at least two electronic devices.
[0018] In some embodiments, the vehicle includes a new energy vehicle, a hybrid vehicle, a range-extended electric vehicle, or a gasoline vehicle. The dimming glass design of this application can be applied to vehicles with different power types to reduce overall vehicle costs and ensure the user's driving experience.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.
[0028] FFC (Flexible Fabric Charge) cables are widely used in various wiring applications requiring lightweight designs due to their flexibility, ability to be bent and folded freely, and thinness. For example, FFC cables are used in automotive wiring harnesses to connect various electronic devices.
[0029] To enable electrical connections between two or more electronic devices, an FFC (Flexible Connection Control) is implemented using a branching mechanism. For example, an FFC consists of a main trunk and two branch lines, both of which are electrically connected to the main trunk. This allows for electrical connections between the electronic devices on the main trunk and the electronic devices on the two branch lines.
[0030] Currently, the connection between two ribbon cables (such as a main line and a branch line) is generally achieved through a ribbon cable connector. This connector typically connects to one end of one ribbon cable, while the other end connects directly to the connector, thus establishing an electrical connection. For example, the connector may have a clamping tab; bending the clamping tab presses the ribbon cable end against the connector to achieve the connection. However, ribbon cables are relatively fragile and can only withstand limited tensile force. Once connected, the connector is prone to breakage under external pulling force, leading to electrical connection failure. Furthermore, this connection method is complex, unsuitable for certain environments (such as a vehicle environment), and costly.
[0031] Therefore, there is an urgent need for a ribbon cable connection structure to solve the above problems.
[0032] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.
[0033] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more” unless the context clearly indicates otherwise.
[0034] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.
[0035] This application provides a ribbon cable connection structure, wherein the structure includes a first ribbon cable, a second ribbon cable, and a crimping piece. To better illustrate the structure of this application, the ribbon cable and the crimping piece are described below.
[0036] In some embodiments, the first and second ribbon cables can be FFC ribbon cables formed using a thermoforming process. FFC ribbon cables generally have a three-layer composite structure: the top and bottom layers are insulating layers, and the middle layer is a conductor layer (or core layer). The core layer typically contains multiple parallel and spaced-apart flat copper wires (for ease of description, this application uses a single flat copper wire as an example). Please refer to... Figure 1 , Figure 1 This is a schematic diagram of an FFC cable provided in an embodiment of this application. The FFC cable includes a conductor layer 1, a first insulating layer 2, and a second insulating layer 3. The conductor layer 1 is disposed between the first insulating layer 2 and the second insulating layer 3. That is, the first insulating layer 2 and the second insulating layer 3 enclose the conductor layer 1 to prevent leakage, damage, etc. in the FFC cable.
[0037] One possible design, considering the need for connection between the first and second ribbon cables, is as follows: the conductor layer 1 at the first end of the first ribbon cable does not have a first insulating layer 2 and / or a second insulating layer 3, and the conductor layer 1 at the first end of the second ribbon cable also does not have a first insulating layer 2 and / or a second insulating layer 3. For example, please refer to [reference needed for the first ribbon cable]. Figure 2 , Figure 2 This is a schematic diagram of a first ribbon cable provided in an embodiment of this application. Figure 2 In Figure a, the conductor layer 1 of the first end of the first ribbon cable (the shaded part protruding on the left end in the figure) does not have a first insulating layer 2 and a second insulating layer 3 (or in other words, the left conductor layer 1 is not wrapped by the first insulating layer 2 and the second insulating layer 3), while the remaining conductor layers 1 are still placed between the first insulating layer 2 and the second insulating layer 3 (or in other words, the right conductor layer 1 is wrapped by the first insulating layer 2 and the second insulating layer 3). Figure 2 In Figure b, the conductor layer 1 at the first end of the first ribbon cable does not have a first insulating layer 2, but has a second insulating layer 3. The remaining conductor layers 1 are still disposed between the first insulating layer 2 and the second insulating layer 3. Figure 2 In Figure c, the conductor layer 1 at the first end of the first ribbon cable does not have a second insulating layer 3, but it does have a first insulating layer 2. The remaining conductor layers 1 are still located between the first insulating layer 2 and the second insulating layer 3. This design is to achieve direct contact between the conductor layers 1 at the overlapping positions of the first and second ribbon cables. A detailed description is provided below. It can be understood that the design of the second ribbon cable is the same as that of the first ribbon cable; a detailed description can be found above, and will not be repeated here.
[0038] It should be noted that the embodiments of this application only use FFC cable as an example, and there is no limitation on the type of cable.
[0039] Figure 3 This is a schematic diagram of the structure of a crimping piece 30 provided in an embodiment of this application. (See attached diagram.) Figure 3 The crimping plate 30 includes a pressure plate 31 and crimping wings 32 arranged perpendicularly to the pressure plate.
[0040] Optionally, the crimping wing 32 is disposed on the same surface of the pressure plate 31. In other words, the crimping wings 32 point in the same direction.
[0041] Optionally, the number of crimping wings 32 is at least two. Figure 2 (Example shown in the figure 4), at least two crimping wings 32 are disposed opposite each other on both sides of the same surface of the pressure plate.
[0042] In this embodiment, the pressing sheet 30 is an integrally formed structure, which can ensure the reliability and stability of the pressing sheet 30.
[0043] Optionally, the crimping tab 30 can be made of a conductive material (or a metal material), or it can be made of a non-conductive material (such as plastic). The preferred option is that the crimping tab 30 is made of a conductive material, so that the first and second rows of wires can conduct electricity through the crimping tab 30.
[0044] The connection structure of the first row of wires, the second row of wires, and the crimping plate is described below.
[0045] Figure 4 This is a schematic diagram of a ribbon cable connection structure provided in an embodiment of this application, with reference to... Figure 4 The ribbon cable connection structure includes a first ribbon cable 10, a second ribbon cable 20, and a crimping piece 30. The first end of the first ribbon cable 10 (left end in the diagram) overlaps with the first end of the second ribbon cable 20 (right end in the diagram). Based on the above... Figure 2 The first ribbon cable 10 has a first insulating layer 2 at its first end, but a second insulating layer 3 is provided. The remaining conductor layers 1 are still located between the first insulating layer 2 and the second insulating layer 3. Similarly, the second ribbon cable 20 has a first insulating layer 2 at its first end (the shaded area on the right), but a second insulating layer 3 is not provided. The remaining conductor layers 1 are still located between the first insulating layer 2 and the second insulating layer 3. Therefore, the conductor layers 1 at the overlapping positions of the first ribbon cable 10 and the second ribbon cable 20 are in direct contact. In other words, the conductor layers 1 of the first ribbon cable 10 and the second ribbon cable 20 are directly overlapping and in contact.
[0046] The crimping tab 30 penetrates the conductor layer 1 where the first ribbon cable 10 and the second ribbon cable 20 are in direct contact (i.e., overlapping position) and presses the conductor layer 1 where the first ribbon cable 10 and the second ribbon cable 20 are in direct contact. Specifically, the crimping wings 32 of the crimping tab 30 penetrate the conductor layer 1 where the first ribbon cable 10 and the second ribbon cable 20 are in direct contact and then bend and tighten, and together with the pressure plate 31, press the conductor layer 1 of the overlapping part of the first ribbon cable 10 and the second ribbon cable 20.
[0047] Optionally, the crimping piece 30 can penetrate from bottom to top (as shown in the figure) or from top to bottom; this embodiment of the application does not limit this. Figure 3 For example, the crimping wing 32 of the crimping tab 30 passes through the second insulating layer 3 at the first end of the first ribbon cable 10, the conductor layer 1 at the first end of the first ribbon cable 10, the conductor layer 1 at the first end of the second ribbon cable 20, and the first insulating layer 2 at the first end of the second ribbon cable 20 from bottom to top. After passing through all the layers, the crimping wing 32 bends and tightens, thereby pressing the conductor layer 1 of the overlapping portion of the first ribbon cable 10 and the second ribbon cable 20 together with the pressure plate 31.
[0048] In summary, the first ribbon cable 10 and the second ribbon cable 20 are connected by a crimping tab 30, eliminating the need for an additional ribbon cable connector. Because the crimping tab 30 has a simple structure and low cost, this connection method is straightforward, resulting in a lower overall cost and applicability to a wider range of working environments. Furthermore, the crimping tab 30 penetrates both the first and second ribbon cables 10 and 20, preventing easy displacement and ensuring connection stability. Additionally, the connection point between the first and second ribbon cables 10 and 20 is directly connected by a conductor layer, allowing direct conductivity and ensuring stable conductivity between them.
[0049] In some embodiments, there are multiple second ribbon cables 20. For ease of description, two second ribbon cables 20 are used as an example. Figure 5 This is a schematic diagram of another ribbon cable connection structure provided in the embodiments of this application, referred to... Figure 5 The ribbon cable connection structure includes a first ribbon cable 10, two second ribbon cables 20, and a crimping piece 30. The first end of the first ribbon cable 10 (left end in the diagram) and the first ends of the two second ribbon cables 20 (right ends in the diagram) are directly overlapped by conductor layers. Specifically, the conductor layer 1 at the first end of the first ribbon cable 10 does not have a first insulating layer 2 and a second insulating layer 3; the remaining conductor layers 1 are still located between the first insulating layer 2 and the second insulating layer 3. The first end (shaded area on the right) of one second ribbon cable 20 (the upper second ribbon cable 20 in the diagram) does not have a second insulating layer 3, but has a first insulating layer 2; the remaining conductor layers 1 are still located between the first insulating layer 2 and the second insulating layer 3. The first end (shaded area on the right) of the other second ribbon cable 20 (the lower second ribbon cable 20 in the diagram) does not have a first insulating layer 2, but has a second insulating layer 3; the remaining conductor layers 1 are still located between the first insulating layer 2 and the second insulating layer 3. Based on this, the conductor layer 1 at the overlapping position of the first ribbon cable 10 and the two second ribbon cables 20 are in direct contact. That is, the conductor layer 1 of the first ribbon cable 10 and the conductor layer 1 of the two second ribbon cables 20 are directly overlapped and in contact.
[0050] The crimping tab 30 penetrates the conductor layer 1 where the first ribbon cable 10 and the second ribbon cable 20 are in direct contact (i.e., overlapping position) and presses the conductor layer 1 where the first ribbon cable 10 and the second ribbon cable 20 are in direct contact. Specifically, the crimping wings 32 of the crimping tab 30 penetrate the conductor layer 1 where the first ribbon cable 10 and the second ribbon cable 20 are in direct contact and then bend and tighten, and together with the pressure plate 31, press the conductor layer 1 of the overlapping part of the first ribbon cable 10 and the second ribbon cable 20.
[0051] The crimping wing 32 of the crimping tab 30 passes through, from bottom to top, the second insulating layer 3 at the first end of the lower second ribbon cable 20, the conductor layer 1 at the first end of the lower second ribbon cable 20, the conductor layer 1 at the first end of the first ribbon cable 10, the conductor layer 1 at the first end of the upper second ribbon cable 20, and the first insulating layer 2 at the first end of the upper second ribbon cable 20. After passing through completely, the crimping wing 32 bends and tightens, thereby pressing the conductor layer 1 of the first ribbon cable 10 and the overlapping portion of the two second ribbon cables 20 together with the pressure plate 31. In this embodiment, each second ribbon cable 20 includes a separate insulating layer, which avoids interference between multiple second ribbon cables 20.
[0052] In some embodiments, the conductor layers of the plurality of second rows of wires 20 may be disposed within the same insulating layer. Figure 6 This is a schematic diagram of another ribbon cable connection structure provided in the embodiments of this application, with reference to... Figure 6 . Figure 6 The connection structure is the same as the above Figure 5 Similar to other embodiments, this application will not repeat the details here. In this embodiment, multiple second rows of wires 20 share an insulating layer, which allows for better conductivity between the multiple second rows of wires 20.
[0053] In some embodiments, the ribbon cable connection structure further includes a first connector and a second connector. The first and second connectors are used for connection to an electronic device. The first and second connectors can optionally be used to connect the same electronic device or different electronic devices; this application is not limited to this. For example, the first connector is a connector for a display, and the second connector is a connector for a controller. To enable electrical connection between the display and the controller, the second end of the first ribbon cable 10 (e.g., ...) can be connected to the second connector. Figure 2 The right end of the middle cable is connected to the first connector, and the second end of the second cable (such as...) Figure 2 The left end is connected to the second connector to achieve this.
[0054] It is understandable that, since the conductor layer of a ribbon cable generally contains multiple parallel and spaced wires, the multiple wires in the first ribbon cable 10 and the second ribbon cable 20 are connected one-to-one via crimp tabs 30. For example, a crimp tab 30 may include a pair of crimping wings 32, and multiple crimp tabs 30 may be used to achieve a one-to-one connection between multiple wires; or, a crimp tab 30 may include multiple pairs of crimping wings 32, with each pair of crimping wings 32 corresponding to a different wire. Considering that the connection method for each wire is the same, this application uses a single flat copper wire as an example for description, and will not elaborate on the connection of multiple wires.
[0055] Based on the above description, this application also provides a vehicle, which includes the above-described wiring connection structure and at least two electronic devices (such as controllers, displays, etc.). The wiring connection structure connects the at least two electronic devices, thereby enabling electrical connection between the at least two electronic devices.
[0056] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
