Description

Technical Field

[0001] This utility model relates to the field of automotive fuse box technology, specifically to an automotive fuse box. Background Technology

[0002] Automotive fuse boxes are primarily used to install automotive fuses to protect various electrical components in a vehicle. The inside of a fuse box is filled with metal conductors. Water or humid air is conductive; if water flows into the fuse box, it can create an unexpected conductive path between conductors of different voltages, causing a short circuit. A short circuit generates a huge instantaneous current that can lead to a vehicle fire. Current fuse boxes are not very waterproof. When a car is in a humid coastal area, salty air can easily enter the fuse box, eventually causing a short circuit in the internal metal conductors. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art that when a car is in a humid coastal area, salty air can easily enter the fuse box, which over time causes a short circuit in the metal conductor inside the fuse box, thereby providing a car fuse box with good sealing performance.

[0004] Therefore, this utility model provides an automotive fuse box, including a base and a cover plate covering the base. The base has multiple receiving slots for accommodating metal conductors. A plug-in structure is provided between the base and the cover plate.

A plug-in structure 4 is provided between the base 1 and the cover plate 2. The plug-in structure 4 includes a plug plate 41 disposed on one of the base 1 or the cover plate 2 and a slot 42 disposed on the other and adapted to the plug plate 41. A sealing gasket 5 is provided in the slot 42. The cover plate 2 is also provided with a wrapping plate 21 that wraps around the plug-in structure 4.

[0027] The specific improvements mentioned above are as follows: Figures 1-3 As shown, the base 1 has multiple receiving slots 3 for accommodating metal, and a metal conductor is inserted into each receiving slot 3. A waterproofing insertion mechanism is provided between the base 1 and the cover plate 2. A sealing gasket 5 is provided inside the insertion structure 4 to enhance the sealing function. To further enhance the waterproof and moisture-proof performance, a wrapping plate 21 is provided on the side of the cover plate 2. The wrapping plate 21 wraps around the outside of the insertion structure 4, thereby effectively preventing rainwater and moisture in the air from entering the housing through the insertion structure 4 and contacting the metal conductor. Through this structural design, three waterproof barriers can be achieved. The wrapping plate 21 can initially block water from entering, the setting of the plug and slot 42 can provide a second waterproof effect, and the setting of the sealing gasket 5 can provide a third waterproof effect. In this way, water and even water vapor suspended in the air can be effectively blocked from the outside, improving the waterproof effect of the entire fuse box.

[0028] Based on the above embodiments: the insert plate 41 is disposed on one side of the cover plate 2, the slot 42 is disposed on one side of the base 1, the base 1 is provided with an extension wall 11 disposed on the side wall of the slot 42, and the wrapping plate 21 and the insert plate 41 are arranged in an "n" shape to form a wrapping groove 22 that wraps the extension wall 11.

A space is left between the extension wall 11 and the slot 42 for the insert plate 41 to be inserted. After the insert plate 41 is inserted into the slot 42, it will abut against the sealing rib 6 on the sealing gasket 5, thereby improving the connection sealing between the slot 42 and the insert block.

[0033] Based on the above embodiments: the metal conductor includes male and female terminals that can be inserted into each other, the receiving groove 3 is used for external metal conductors to pass through, the receiving groove 3 includes a first insertion end 31 for inserting the male terminal and a second insertion end 32 for inserting the female terminal, the first insertion end 31 is provided with a first abutting post 33 that can abut against the male terminal, and the second insertion end 32 is provided with a second abutting post 34 that can abut against the female terminal.

[0034] The specific improvements mentioned above are as follows: Figure 5 As shown, the metal conductor includes male and female terminals that can be interlocked (contact resistance between male and female terminals ≤1.5mΩ ≤2.0mΩ 10A, DC load rated current 25A, ambient temperature insulation resistance ≥100MΩ). The receiving groove 3 includes a first insertion end 31 for inserting the male terminal and a second insertion end 32 for inserting the female terminal. The first insertion end 31 is provided with a first abutting post 33 that can abut against the male terminal, and the second insertion end 32 is provided with a first abutting post 33 that can abut against the female terminal. During the connection process, the male terminal is inserted from the first insertion end 31 until it abuts against the first abutment post 33, and the female terminal is simultaneously inserted from the second insertion end 32 until it abuts against the second abutment post 34. At the same time, the male and female terminals are connected. The first abutment post 33 and the second abutment post 34 are designed to prevent damage to the terminals caused by excessive force during the connection process.

[0036] The specific improvements mentioned above are as follows: Figure 1 and Figure 2The fastening block 7 and the fastening ring 71 ensure a stable connection between the base 1 and the cover plate 2.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
