Abstract
The invention discloses an automobile fuse with indication. The automobile fuse is characterized by comprising package, terminals and an indication device, wherein the package is a cuboid, the terminals are two pins which are led from a bottom surface of the cuboid and are symmetric to each other in a left-right way, an upper cavity and a lower cavity are arranged in the cuboid between inner ends of the terminals and are partitioned by a partition plate, a fuse wire is arranged in the lower cavity and is connected with the two terminals, the indication device is provided with a light emitting diode and a resistor in the upper cavity, a negative electrode of the light emitting diode is connected with one end of the resistor, the other end of the resistor is connected with one of the terminals, and a positive electrode of the light emitting diode is connected with the other terminal. After a post-stage short-circuit load fuse wire is burnt out, a voltage between the two terminals rises, a current passes through the light emitting diode under a current-limiting effect of the resistor to give out light, and the fact that the fuse is burnt out and which fuse is burnt one is easy to judge; and due to the arrangement of the upper cavity and the lower cavity, the indication device cannot be affected by spraying when the fuse wire is burnt out.
Description
Technical field
The present invention relates to a kind of various for motor vehicle insurances, more particularly to a kind of with the car insurance for indicating.
Background technology
Automobile is huge as vehicles recoverable amount, and the composition of automobile is related to various electric appliance circuits, in order to ensure each circuit
Circuit will not be burnt in overload, Arming Assembly during Automobile Design, is designed with, each line powering is by Arming Assembly on car
It is each to insure branch out, when insurance back-end component appearance exception causes electric current excessive and produces overload, to insurable just
Can fuse and avoid fault coverage and loss from spreading expansion, as interior space is limited, safety box is difficult to arrange excessive, and insures number
Amount is again more, thus insurance arrange all compare comparatively dense, if having that fuse melting and concrete which fuse melting all do not have clearly
Indicate, it is determined that and position it is relatively difficult, still await technology solution.
The content of the invention
In order to solve the above problems, the invention provides a kind of with the car insurance for indicating.
The technical solution used in the present invention is：A kind of car insurance with instruction, it is characterised in that including encapsulation, terminal
And instruction device, cuboid is encapsulated as, terminal is to draw symmetrical two feet by the bottom surface of cuboid, between terminal the inner
Rectangular to be provided with the epicoele and cavity of resorption separated by dividing plate in vivo, lower intracavity is provided with the electric fuse of connection two-terminal, and instruction device exists
Upper intracavity is provided with light emitting diode and resistance, light emitting diode negative pole and the connection of resistance one end, the resistance other end and a terminal
Connection, light emitting diode positive pole are connected with another terminal.
Further, on the terminal being connected with light emitting diode positive pole and/or the terminal side packing is provided with labelling.
Further, the light emitting diode is located at upper intracavity vacantly, is encapsulated as transparent or semitransparent.
Further, the light emitting diode is embedded in encapsulation, is exposed on encapsulation.
Further, described terminal the inner is provided with through hole.
The terminal that the present invention is connected with light emitting diode positive pole when using is connected with power supply positive pole, and another terminal is electricity
Source cathode output end provides power supply for circuit below, and during normal work, between two-terminal, voltage is very low, less than light emitting diode
Conducting voltage, light emitting diode do not light, and after rear class short circuit overload blown fuse, between two-terminal, voltage is raised, in resistance
Under metering function, light emitting diode has electric current by luminous, it is easy to judge fuse melting and which fuse melting, upper and lower two-chamber
Sputtering when arranging blown fuse does not interfere with instruction device.
Description of the drawings
Fig. 1 is embodiment of the present invention integral perspective schematic diagram.
Fig. 2 is embodiment of the present invention cross-sectional schematic.
Reference:1 encapsulation；2 terminals；3 epicoeles；4 cavity of resorptions；5 electric fuses；6 light emitting diodes；7 resistance.
Specific embodiment
The embodiment of the present invention as shown in Figure 1, 2, should be provided with encapsulation 1, terminal 2 with the car insurance for indicating and indicate dress
Putting, being encapsulated as cuboid, terminal is symmetrical two feet to be drawn by the bottom surface of cuboid, rectangular internal between terminal the inner
The epicoele 3 and cavity of resorption 4 separated by dividing plate is provided with, lower intracavity is provided with the electric fuse 5 of connection two-terminal, and instruction device is in upper intracavity
Light emitting diode 6 and resistance 7, light emitting diode negative pole and the connection of resistance one end are provided with, the resistance other end is connected with a terminal,
Light emitting diode positive pole is connected with another terminal, constitutes loop, and when rear class short circuit blown fuse, resistance limits electric current and exists
1 to 5 milliampere, lumination of light emitting diode, the present embodiment light emitting diode is embedded in encapsulation, expose on encapsulation, work as encapsulation
For transparent or semitransparent, light emitting diode also can appear instruction light hanging in epicoele when luminous.
The terminal that the present invention is connected with light emitting diode positive pole when using is connected with power supply positive pole, and another terminal is electricity
Source cathode output end provides power supply for circuit below, and during normal work, between two-terminal, voltage is very low, less than light emitting diode
Conducting voltage, light emitting diode do not light, and after rear class short circuit overload blown fuse, between two-terminal, voltage is raised, in resistance
Under metering function, light emitting diode has electric current by luminous, it is easy to judge fuse melting and which fuse melting, upper and lower two-chamber
Sputtering when arranging blown fuse does not interfere with instruction device.
During enforcement, labelling can be set on the terminal being connected with light emitting diode positive pole and/or on the terminal side packing, can
It is anti-inserted to prevent, it is also possible to which that do two-terminal one is wider than another, and two jack of socket is adapted to width terminal respectively, can be with
Preferably prevent anti-inserted；Through hole can be provided with terminal the inner, encapsulation is provided with the locating dowel for probeing into through hole so as to connect with encapsulation
Connect more stable firm.
It is only present pre-ferred embodiments in sum, all equivalent modifications done according to the application and prior art addition are equal
It is considered as the technology of the present invention category.
