Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a multi-functional wiring board for vehicles. Background Technology

[0002] In vehicle electrical systems, especially in commercial vehicles, special vehicles, or automotive modifications, there is often a need to provide stable and reliable power interfaces for additional electrical equipment (such as lights, audio systems, and navigation systems). Traditional solutions often use direct wire stripping connections, ordinary terminal blocks, or simple splitters. These methods have significant drawbacks: First, exposed wiring connections are prone to loosening and detachment due to continuous vibrations during vehicle operation, leading to poor contact or even short circuits, posing safety hazards. Second, the lack of integrated overcurrent protection mechanisms usually requires the addition of a fuse box on the main line, increasing wiring complexity and potential failure points. Third, traditional wiring methods make it difficult to centralize and standardize power supply for multiple electrical devices, resulting in messy wiring harnesses that are inconvenient for installation, maintenance, and management. Utility Model Content

[0003] In response, this utility model provides a multi-functional terminal block for vehicles that integrates power distribution, provides a stable connection, and has protective functions.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides a multi-functional terminal block for vehicles, including an insulating base and a conductive bar; the insulating base has multiple hollow plugs integrally formed on its surface; the conductive bar includes a positive conductive bar and a negative conductive bar, which are injection molded inside the insulating base and each has a positive plug and a negative plug extending into each plug; the insulating base is provided with a fuse access position, and the positive conductive bar has a break at the fuse access position, with fuse connection feet on both sides of the break.

[0006] Preferably, the conductive busbar further includes a ground conductive busbar, which is injection molded inside the insulating base and has a grounding pin extending into the plug.

[0007] Preferably, the grounding busbar has an external pin at its end, and the insulating base has a connection port for the external pin to extend into.

[0008] Preferably, the insulating base has a sleeve surrounding the fuse connection foot at the fuse input position, and the sleeve is equipped with a protective cover.

[0009] Preferably, the edge of the insulating base is provided with a fixing plate, and the fixing plate is provided with fixing holes.

[0010] Preferably, the positive and negative conductive busbars are connected to terminals, and the terminals include a wiring screw fixed to the insulating base and connected to the corresponding conductive busbar, and a wire clamping nut screwed onto the wiring screw.

[0011] Preferably, a sealing device is detachably provided at the insertion tube.

[0012] Preferably, the sealing device includes a sealing cap and a sealing ring disposed on the sealing cap. The sealing cap is provided with a first buckle, and the outer side of the insert is provided with a second buckle. After the sealing cap is inserted into the insert, the sealing ring seals the gap between the sealing cap and the inner wall of the insert, and the second buckle engages with the first buckle.

[0013] The positive effects of this utility model are as follows: This multi-functional junction box, by setting multiple sockets on the insulating base and setting corresponding pins in each socket for each conductive bar, allows one junction box to provide power interfaces for multiple electrical devices simultaneously. This solves the cumbersome problem of needing to lay multiple independent terminals in traditional wiring methods. It not only simplifies the wiring layout inside the vehicle and saves installation space, but also makes power distribution more centralized and orderly. Power can be quickly obtained simply by inserting the plugs of electrical devices with different functions into the corresponding sockets, improving ease of use. Furthermore, the conductive bar is injection-molded into the insulating base to form a single unit, ensuring reliable fixing and preventing loosening, detachment, and poor contact caused by continuous vibration under harsh road conditions. In addition, due to the fuse access point and fuse connection pins, in actual use, the fuse can be connected between two fuse connection pins and connected in series in the positive circuit, providing circuit protection and eliminating the need for an external fuse box.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0023] The structure of the vehicle multi-functional wiring board of this utility model embodiment is as follows: Figures 1 to 5 As shown, it includes an insulating base 1 and a conductive bar; the insulating base 1 has multiple hollow inserts 11 integrally formed on its surface; the conductive bar includes a positive conductive bar 2 and a negative conductive bar 3, the positive conductive bar 2 and the negative conductive bar 3 are injection molded inside the insulating base 1 and each has a positive plug 21 and a negative plug 31 extending into each insert 11; the insulating base 1 is provided with a fuse access position 12, the positive conductive bar 2 has a break 22 formed at the fuse access position 12, and fuse connection feet 2 are provided on both sides of the break 22. 3; During use, each functional plug is inserted into the socket 11 and connected to the positive terminal 21 and the negative terminal 31 to achieve circuit conduction; and due to the setting of the fuse access position 12 and the fuse connection pin 23, in actual use, the fuse unit can be connected between the two fuse connection pins 23 and connected in series in the positive circuit to play a circuit protection role; in addition, the injection molding process makes the conductive busbar and the insulating base 1 firmly combined into a whole, avoiding the problem of loose wiring, detachment or poor contact caused by continuous vibration of the vehicle under bad road conditions.

[0024] In a preferred embodiment, the conductive busbar further includes a grounding conductive busbar 4, which is injection molded inside the insulating base 1 and has a grounding pin 41 extending into the plug tube 11. The introduction of the grounding conductive busbar 4 provides a grounding path, which can effectively prevent safety hazards caused by leakage or short circuit, improve the safety performance of the terminal block, and ensure the stable operation of the vehicle's electrical system.

[0025] like Figure 3 As shown, the grounding conductor 4 has an external pin 42 at its end, and the insulating base 1 has a connection socket 13 for the external pin 42 to extend into. The connection socket 13 is for the plug of the external grounding wire to be plugged in. This design facilitates the connection of the external grounding wire by plugging in, and improves the ease of operation.

[0026] like Figure 2 and Figure 3 As shown, a sleeve 14 is provided on the insulating base 1 around the fuse connection foot 23 at the fuse access position 12. The sleeve 14 is equipped with a protective cover (not shown in the figure). When the protective cover is fitted on the sleeve 14, it can protect the fuse connection foot 23 and the installed fuse unit from dust and water. When replacing the fuse unit, the protective cover can be removed.

[0027] In some embodiments, the edge of the insulating base 1 is provided with a fixing plate 15, and the fixing plate 15 is provided with a fixing hole 151. When installing the terminal block, screws are used to pass through the fixing hole 151 and fix it to the vehicle body, so that the terminal block is firmly installed in a specific position of the vehicle, preventing it from shifting or loosening due to vibration during driving, and improving the overall stability of the terminal block.

[0028] For example, the positive electrode conductive bus 2 and the negative electrode conductive bus 3 are connected to terminal blocks 5. The terminal blocks 5 are used to connect external wires. The terminal blocks 5 include a terminal screw 51 fixed to the insulating base 1 and connected to the corresponding conductive bus, and a wire clamping nut 52 screwed onto the terminal screw 51. The external wires are connected to the terminal screw 51 by being clamped by the wire clamping nut 52.

[0029] In some embodiments, a sealing device 6 is detachably provided at the plug 11. By providing the sealing device 6, when the corresponding power interface is idle, the sealing device 6 is installed to close the opening of the plug 11, which can effectively prevent moisture, dust and other contaminants from entering the interior of the plug 11 and protect the plug pins from corrosion or short circuit. When in use, the sealing device 6 can be removed from the plug 11.

[0030] For details, please refer to Figure 4As shown, the sealing device 6 includes a sealing cover 61 and a sealing ring 62 disposed on the sealing cover 61. The sealing cover 61 is provided with a first buckle 63, and the outer side of the insert 11 is provided with a second buckle 16. After the sealing cover 61 is inserted into the insert 11, the sealing ring 62 seals the gap between the sealing cover 61 and the inner wall of the insert, effectively isolating external contaminants. The second buckle 16 and the first buckle 63 form a snap-fit, thus ensuring that the sealing cover 61 is reliably installed on the insert 11. The arrangement of the first buckle 63 and the second buckle 16 makes the sealing device 6 easy to install and disassemble.

[0031] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
