Safety device

Abstract

The invention discloses a safety device which comprises an upper cover and a shell, and one side of the upper cover is rotatably connected with one side of the shell. The side surface of the upper cover is provided with a vertical surface facing downwards, the vertical surface, away from the rotating connecting position, of the upper cover is provided with a clamping hole, a limiting clamp is arranged in the clamping hole, the limiting clamp is provided with a locking rod facing the outer side of the upper cover, and the locking rod is located below the vertical surface. The shell comprises a protective shell, a boss protruding outwards is arranged above the protective shell, a clamping groove is formed in the side, corresponding to the clamping hole, of the boss, the limiting clamp can be clamped in the clamping groove, and the locking rod is used for fastening the clamping groove and the limiting clamp. An assembling part and a conducting piece are further arranged in the shell, and the conducting piece is fixed to the assembling part and used for being connected with a power input wire. According to the invention, whether the power input of the fuse conduction sheet is normal or not can be measured without pulling out the fuse conduction sheet from the base so that unnecessary damage to the fuse is avoided, and unnecessary losses caused by replacement of the fuse by a user to subsequent vehicle recovery are reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, and more specifically, to a safety device. Background technique [0002] The number of fuses on the car is very large, basically every control circuit will have an insurance, the insurance has the difference between fast-melting and slow-melting, the conductive piece of the fast-melting fuse is exposed at the top of the fuse, and the conductive piece of the slow-melting fuse Inside the safe case, not exposed. If a power circuit does not work, to check whether the power supply of the fuse is provided, you can pull out the fuse from the base and measure whether the connecting piece on the base of the fuse is powered on to determine whether the fuse has power and provide for subsequent checks. Direction, because the conductive piece of the fast-acting fuse is exposed, it is not necessary to pull out the fuse from the base to measure whether the power supply of the fuse is normal, while the slow...

If a power circuit does not work, to check whether the power supply of the fuse is provided, you can pull out the fuse from the base and measure whether the connecting piece on the base of the fuse is powered on to determine whether the fuse has power and provide for subsequent checks. Direction, because the conductive piece of the fast-acting fuse is exposed, it is not necessary to pull out the fuse from the base to measure whether the power supply of the fuse is normal, while the slow-melt fuse needs to be pulled out from the base to measure because the conductive piece is not exposed. , and because the number of insurance and relays on the insurance base is relatively large and the arrangement is relatively dense, it is easy to cause damage to the insurance when improperly operated, and it is necessary to replace the insurance to cause unnecessary losses to subsequent vehicle recovery
