Description

Technical Field

[0001] This utility model relates to an automotive fuse, specifically a flat plug-in automotive fuse. Background Technology

[0002] A flat-panel pluggable automotive fuse is a type of automotive fuse designed to fit securely in the circuit like a sturdy shield, offering vibration resistance and preventing loosening. These fuses are commonly used in automotive circuits and cover a wide current range, from 60A to 350A.

[0003] In existing flat plug-in automotive fuses, the conductive metal strip inside is usually fixed to the housing. While this provides a basic fixing effect, the conductive metal strip is constantly in motion as the car moves. Over time, a slight resonance will occur between the conductive metal strip and the housing, causing the gap between the conductive metal strip and the housing to gradually increase, ultimately increasing the risk of damage to the car's internal circuitry. Utility Model Content

[0004] The purpose of this invention is to provide a flat pluggable automotive fuse, in which two sets of clamping components are used to clamp two conductive metal sheets respectively. The pressure-bearing airbag can prevent the conductive metal sheets from being damaged by pressure, and can maintain good vibration resistance during use, effectively protecting the circuit.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flat pluggable automotive fuse, comprising a housing and a main body disposed on the housing, and a clamping assembly disposed on the housing. The housing includes an upper housing and a lower housing fixed to the upper housing. Two mounting slots are provided on the opposite side of the upper and lower housings. The main body includes two conductive metal sheets and a molten material connected between the two conductive metal sheets. The two conductive metal sheets are respectively disposed in the two mounting slots. Terminals are connected to both conductive metal sheets. The clamping assembly includes a fixing cap and a screw threaded into the fixing cap. An inner pressure block is fixed at the bottom of the screw. A pressure-bearing airbag is disposed below the inner pressure block. The pressure-bearing airbag wraps around the outside of the conductive metal sheets and is in contact with the conductive metal sheets.

[0006] Preferably, a central groove is provided between the two mounting grooves, the melt is placed in the central groove, and the pressure-bearing airbag is tightly fitted to the inner wall of the mounting groove.

[0007] Preferably, four top grooves are provided on the upper end face of the upper shell, and bolts are installed in each of the four top grooves, with all four bolts driven into the lower shell.

[0008] Preferably, the fixing cap is fixed inside the upper housing, and a knob is connected to the end of the screw away from the inner pressure block.

[0009] Preferably, the inner pressure block is pressed onto the upper end face of the conductive metal sheet, and both ends of the inner pressure block are provided with matching grooves.

[0010] Preferably, the pressure-bearing airbag includes a bottom airbag and side airbags respectively disposed at both ends of the bottom airbag, and a top airbag block is disposed at the end of each side airbag away from the bottom airbag.

[0011] Preferably, the pressure-bearing airbag has an internally hollow cavity structure, and the pressure value inside the pressure-bearing airbag is greater than one standard atmosphere.

[0012] Preferably, the bottom bladder is bonded and fixed to the inner wall of the mounting groove, and the side bladders at both ends of the bottom bladder are symmetrically arranged.

[0013] Preferably, there are two sets of clamping components, and the two sets of clamping components are symmetrical about both ends of the housing. The two sets of clamping components are used to limit the two conductive metal sheets respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention features two sets of clamping components on the upper housing. These components are used to clamp two conductive metal sheets, while the presence of a pressure-bearing airbag prevents the conductive metal sheets from being damaged by pressure. This ensures that the conductive metal sheets maintain good vibration resistance during use, allowing the flat plug-in automotive fuse to function even when the car is under vibration for extended periods, thus guaranteeing the safety of the car's electrical circuits.

[0027] Please see Figure 1One embodiment of this utility model is a flat pluggable automotive fuse, which includes a housing 1 and a main body 2 disposed on the housing 1. Two sets of clamping components 3 are also disposed on the housing 1, and the two sets of clamping components 3 are symmetrical about the two ends of the housing 1.

[0028] Please see Figure 2 The outer casing 1 includes an upper casing 11 and a lower casing 12 fixed to the upper casing 11. Four top grooves 113 are provided on the upper end face of the upper casing 11. The clamping assembly 3 includes a fixing cap 31 and a screw 32 threadedly installed in the fixing cap 31. The fixing cap 31 is fixed inside the upper casing 11. A knob 33 is connected to the top of the screw 32. The knob 33 is used for hand gripping.

[0029] Please see Figure 3 The main body 2 includes two conductive metal sheets 21 and a melt 22 connected between the two conductive metal sheets 21. Two sets of clamping components 3 are used to limit the two conductive metal sheets 21 respectively. Terminals 23 are connected to both conductive metal sheets 21.

[0030] Please see Figure 4 Bolts 13 are installed in each of the four top grooves 113, and the four bolts 13 are driven into the lower housing 12, so that the upper housing 11 is fixed to the lower housing 12 as one unit by the four bolts 13.

[0031] Please see Figure 5 Two mounting grooves 111 are provided on the opposite side of the upper housing 11 and the lower housing 12. Two conductive metal sheets 21 are respectively disposed in the two mounting grooves 111. A central groove 112 is provided between the two mounting grooves 111. The melt 22 is disposed in the central groove 112. An inner pressure block 34 is fixed at the bottom of the screw 32. The inner pressure block 34 is pressed against the upper end face of the conductive metal sheet 21. A pressure-bearing airbag 35 is provided below the inner pressure block 34. Both the inner pressure block 34 and the pressure-bearing airbag 35 are disposed in the mounting grooves 111. The pressure-bearing airbag 35 wraps around the outside of the conductive metal sheet 21 and is in close contact with the conductive metal sheet 21.

When the two top bladder blocks 353 are respectively inserted into the two matching grooves 341, the inner pressure block 34 and the pressure-bearing airbag 35 completely wrap the conductive metal sheet 21. At the same time, the inner pressure block 34 and the pressure-bearing airbag 35 exert pressure on the conductive metal sheet 21 and fix the conductive metal sheet 21, thereby greatly reducing the vibration of the conductive metal sheet 21.
