Description

Technical Field

[0001] This utility model belongs to the field of fuse box technology, and in particular relates to a fuse box that is easy to wire and install. Background Technology

[0002] In automotive electrical systems, fuse boxes are used to safely and orderly distribute electrical energy from the battery and engine to various electrical devices and to provide circuit protection. In order to isolate the risk of interference between other devices on the same circuit, branch fuse boxes are usually used to connect the devices to the circuit, thereby preventing the failure of the device from affecting other functions of the car. However, due to the limited installation space inside the car, the installation location and wiring method of fuse boxes are restricted, making it impossible to flexibly arrange the in-vehicle circuits.

[0003] This invention designs a fuse box that is easy to wire and install, thus solving the above problems. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A fuse box for easy wiring and installation includes a base. A first busbar, a second busbar, a first bolt, a second bolt, and a third bolt are installed inside the base. One end of the first busbar is connected to the first bolt. A fuse slot is provided inside the base, and a fuse is installed in the fuse slot. The other end of the first busbar extends into the fuse slot and connects to the fuse. The middle of the second busbar extends into the fuse slot and connects to the fuse. Both ends of the second busbar are connected to the second bolt and the third bolt, respectively. A fuse assembly connected to the third bolt is installed inside the base. The central axis of the first bolt is inclined along the bottom surface of the base, and the central axis of the second bolt is perpendicular to the bottom surface of the base. A top cover is installed on the base.

[0005] As a preferred embodiment, the second busbar and the fuse assembly are secured to the base by snap-fit.

[0006] As a preferred embodiment, the second bolt is connected to the first nut, and the third bolt is connected to the second nut.

[0007] As a preferred option, the base is provided with an unused slot.

[0008] As a preferred option, the top cover is fixed to the base by a snap-fit ​​mechanism, and the top cover covers the upper part of the base.

[0009] As a preferred option, the base is provided with a waist hole.

[0010] Compared with existing technologies, the advantages of this utility model are: 1. This utility model has a three-way wiring function, with the terminals being a first bolt, a second bolt, and a fuse assembly. The fuse assembly is in the form of a connector. The first bolt and the second bolt are located in different positions inside the base, and the first bolt and the second bolt are set at different angles inside the base. This reduces the vertical space requirement, allows the wiring harness to be laid out flat, and allows for more natural and gentle bending and routing, reducing mechanical stress at the wire connection points. Therefore, the fuse box can be installed in a smaller space, improving the flexibility of the overall vehicle layout.

[0011] 2. This utility model allows for the selection of female terminals for output lines based on requirements, facilitating wiring. Furthermore, depending on the different terminals, this fuse box can be configured with different fuse amperage ratings, with another terminal serving as a backup. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0017] A fuse box that is easy to install and wire, such as Figures 1 to 3 As shown, the device includes a base 1, in which a first busbar 2, a second busbar 3, a first bolt 4, a second bolt 5, and a third bolt 6 are installed. One end of the first busbar 2 is connected to the first bolt 4. A safety slot 14 is provided in the base 1, and a safety piece 7 is installed in the safety slot 14. The other end of the first busbar 2 extends into the safety slot 14 and is connected to the safety piece 7. The middle of the second busbar 3 extends into the safety slot 14 and is connected to the safety piece 7. The two ends of the second busbar 3 are connected to the second bolt 5 and the third bolt 6, respectively. A safety assembly 8 connected to the third bolt 6 is installed in the base 1. The central axis of the first bolt 4 is inclined along the bottom surface of the base 1. The central axis of the second bolt 5 is perpendicular to the bottom surface of the base 1. A top cover 9 is installed on the base 1.

[0018] This fuse box has a three-way output function, with the terminals being the first bolt 4, the second bolt 5, and the fuse assembly 8. The fuse assembly 8 is in the form of a connector. The first bolt 4 and the second bolt 5 are located in different positions inside the base 1, and the first bolt 4 and the second bolt 5 are set at different angles inside the base 1. For example, the first bolt 4 is set at an angle of 45° relative to the bottom surface of the base 1, which can reduce the vertical space requirement. The wiring harness can bend and run at a more natural and gentle angle, reducing the mechanical stress at the connection of the wire ends. Therefore, the fuse box can be installed in a smaller space, improving the flexibility of the overall vehicle layout. In addition, the female terminal can be selected according to the needs of the wiring to facilitate wiring. Depending on the different terminals, this fuse box can be selected with different fuse amperage ratings, and another terminal is used as a spare.

[0019] The second busbar 3 and the fuse assembly 8 are fixed in the base 1 by snap-fit. The second bolt 5 is connected to the first nut 10, and the third bolt 6 is connected to the second nut 11. The first nut 10 is used to fix the connection between the second busbar 3 and the second bolt 5, and the second nut 11 is used to fix the connection between the second busbar 3, the fuse assembly 8, and the third bolt 6.

[0020] The first busbar 2, the first bolt 4, the second bolt 5, and the third bolt 6 are all integrally injection molded with the base 1. That is, in the injection molding process of the base 1, the first busbar 2, the first bolt 4, the second bolt 5, and the third bolt 6 are placed in designated positions within the mold of the base 1. After the base 1 is injection molded within the mold, the first busbar 2, the first bolt 4, the second bolt 5, and the third bolt 6 are fixed within the base 1, making the installation connection between the components more secure and stable.

[0021] The base 1 has a spare slot 12. The spare slot 12 is used to place spare fuses.

[0022] The top cover 9 is fixed to the base 1 by a snap-fit, and the top cover 9 covers the upper end of the base 1.

[0023] The base 1 is provided with a waist hole 13. A washer is provided in the waist hole 13. The base 1 can be installed on sheet metal through the waist hole 13 and bolt fasteners. The installation distance can be adjusted within the range of the waist hole 13.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
