Fuse holder in the material, structure, wiring and the introduction of the difference

Fuse material is mainly made of aluminum antimony alloy and other low-melting alloy.Fuse must be easy to melt the wire, in order to fuse in time when the current is large, play a protective role, so usually lead antimony wire.

Structure of fuse:

General fuse consists of three parts:

It is melt part, it is the core of fuse, fuse to cut off the role of the current, the same type, the same specification of fuse melt, material to the same, geometric size to the same, resistance value as far as possible small and consistent, the most important is the fuse characteristics to be consistent, household fuse commonly made of lead antimony alloy;

The second is the electrode part, usually has two, it is the melt and the circuit connection important part, it must have the good conductivity, should not produce the obvious installation contact resistance;

Part three is stents, the fuse melts is generally fine soft, the role of stents is to melt and make three parts fixed rigid overall ease of installation, use, it must have good mechanical strength, insulation, heat resistance and flame retardant, in use should not produce the phenomenon such as fracture, deformation, combustion and short circuit.

So how does the fuse holder work?

Methods;Fire (101) is introduced into the power cord to a socket, the zero line of the two line pressing screw socket on the left side of the screw, wire joint insurance first side, the other side of the insurance wire connected to the outlet line pressing on the right side screw (above average household to choose four square with lines or 2.5 square copper wire) and on the right side of the connection screw press with a piece of not less than 0.75 square copper core of receiving switch, switch another connection of the screw can be connected to the lamp, the lamp will need to be directly connected to the zero line

The following introduces the difference between temperature fuse and current fuse:

Temperature fuses can sense the overheating of electrical and electronic products during abnormal operation, thus cutting off the circuit to avoid fire.Commonly used: hair dryer, electric iron, electric rice cooker, electric stove, transformer, electric motor, water dispenser, coffee pot, etc., the temperature fuse cannot be used again after operation, only once under the fusing temperature.

Also known as current fuses or fuses, IEC127 defines fuse as a "fuse-link" made of a silver-copper alloy with a high resistivity and a low melting point.When the current is abnormally raised to a certain height and certain heat, the fuse will fuse itself to cut off the current, so as to protect the safe operation of the circuit.

Similarities: both are too hot to fuse

Different points: temperature fuse when the temperature is high, but the current is not necessarily high;When the current fuse is blown, the temperature is high, so is the current.

Huizhou HINEW Electric Appliance Co., Ltd. was founded in 2000, specializing in the development and production of electronic components such as fuse box,safety tube seat, fuse base, automobile fuse box, switch, socket, thermostat, etc.This company has sales department,technical department,injection department, mold department, hardware department, assembly department QC and other departments.
