Abstract
The utility model provides a multi-function circuit protector, which belongs to the technical field of electric supply and is composed of a power supply line, an insulation tube, a mercury ball, a metal sheet switch knob, an indicating light, etc. The utility model can replace traditional fuse and knife switch and combine three functions of circuit safety, short circuit indication and switch. When the electric circuit brings about overload short circuit, the utility model can cut off the power automatically and cut off the electricity supply, and the indicating light brightens to indicate. After the defective circuit is repaired, the switch knob is twisted, and then the electric supply to the electric appliances is recovered. The utility model has the advantages of convenient use and material saving, avoid the trouble of fuse replacement of the traditional knife switch.
Description
The multifunctional circuit safeties belong to for using electrical domain, relate in particular to for the switch safeties with electric line.
Current all is to adopt fuse to prick to be connected with circuit on ceramics seat for the safeties that use with electrical domain, or fuse pricks on knife switch, when circuit is short-circuited or during the voltage overload, and blown fuse and work to protect electrical appliance.The shortcoming of this safeties is: needing to change fuse after blown fuse, not only bothered but also wasted metal material, is to meet this thing for the family that lacks electricity consumption general knowledge to feel a delicacy about especially again, at a loss as to what to do.
The purpose of this utility model is at above-mentioned shortcoming, provides a kind of without fuse, and has the circuit safeties of insurance, warning, the multi-functional combination of switch.
The utility model is realized in the following way: utilize the mercury focus low, the principle of expanded by heating.Adopt the connecting terminal of mercury as live wire, two connecting terminals promptly are set on a live wire, on two connecting terminals live wire is inserted turn-knob switch both sides respectively, again a live wire is received electrical appliance, one is inserted indicator light.Zero line inserts an end of a joint carbon rod, at the carbon rod other end zero line is received indicator light and electrical appliance.During normal electricity consumption; mercury bead is on a connecting terminal; electrical appliance gets electric work; when being short-circuited or overloading, connecting terminal heating, past another connecting terminal of mercury bead expanded by heating jumping; the outage of electrical appliance circuit; electrical appliance does not have electricity and is protected, and it is shinny to indicate (warning) circuit for lamp to connect, and indication does not have with electric line.After overhauling handy electric line, turn round turn-knob switch, electrical appliance gets electric resuming work, and connects that to show that lamp does not have electricity not shinny, and said process repeats.The switch turn-knob is provided with close stance, and turn-knob is turned round close stance, and electricity all must not be electric with device and indicator light, and realized this device purpose.
Advantage of the present utility model: this device has replaced fuse with mercury bead, has avoided the traditional insurance device to change the trouble of fuse, and is extremely easy to use; Save metal material simultaneously.Can protect in addition the safety of electrical appliance, can indicate with the electric line internal short-circuit again, open circuit and whether external circuit has electricity, and have the function of switch.
Describe the utility model in detail below in conjunction with accompanying drawing:
Description of drawings, this accompanying drawing are this structure drawing of device.
Zero line in the accompanying drawing (1) inserts carbon rod (3), from carbon rod (3) zero line (1) is inserted indicator light (13) and electrical appliance.Make the middle part with a heat-resistant insulation tube (4) and make progress little curvedly, an amount of mercury bead (5) is placed in the insulated tube (4), every of insulated tube (4) be provided with respectively two sheet metals spaced intermediate (6),
, (7),
With live wire (2) receive sheet metal (6) and
On, again from gold plaque (7)
Two live wires (2) are received switch turn-knob (8).Switch turn-knob (8) be provided with 8 contact positions (a) (b) (c) (d) (e) (f) (g) (h), per 4 contact positions, front and back are connected.Establish input spring contact strip (9) and delivery spring contact (10) respectively in the contact position of switch turn-knob (8) (b) with (d), from the sheet metal (7) of insulated tube (4) live wire (2) is inserted spring input contact (9), live wire (2) is connected to electrical appliance from delivery spring contact (10).Establish delivery spring contact (12) and input spring contact strip (11) respectively in the contact position of switch turn-knob (8) (e) with (g), from the sheet metal (7) of insulated tube (4) live wire (2) is inserted input spring contact strip (11), from delivery spring contact (12) live wire (2) is inserted indicator light again.
The course of work: the normal input of electricity is being arranged, when mercury bead (5) is in insulated tube (4) right-hand member, mercury bead (5) is connected sheet metal (6) and (7), positive electricity promptly feeds the input spring contact strip (9) of switch turn-knob (8), (a) (b) (c) (d) contact the position electric, be transported to electrical appliance through delivery spring contact (10); Negative electricity is transported to electrical appliance and indicator light (13) through carbon rod (3), and at this moment, electrical appliance gets electric operate as normal, and indicator light (13) does not have positive electricity and be not shinny.If take place under excess load, the short-circuit conditions, sheet metal (6) (7) heating in the insulated tube (4), mercury bead (5) promptly generate heat to expanding and jumps left end toward insulated tube (4), and sheet metal (6) (7) disconnection makes the electrical appliance must not positive electricity and do not work.Mercury bead (5) is with sheet metal
Connect, (e) of switch turn-knob (8) (f) (g) (h) contact the position electric, positive electricity enters indicator light (13) through delivery spring contact (12), the electricity consumption line short is indicated in the shinny warning of indicator light (13).After short circuit line is overhauled, switch turn-knob (8) to be turned right turn round, contact position (h) is connected with delivery spring contact (10), and electrical appliance gets electric work, and delivery spring contact (12) must not electricity, indicator light (13) is not shinny.When overload once more, short circuit phenomenon, mercury bead (5) is jumped toward right-hand member from insulated tube (4) left end, delivery spring contact (10) must not electricity, whole promptly do not have with electric line.And (a) (b) (c) (d) contact position electric, delivery spring contact (12) contact electricly with (a), so indicator light (13) gets electric indication.After having overhauled fault, switch turn-knob (8) is turned left turn round again, delivery spring contact (10) electric, electrical appliance also electric work.Above-mentioned working procedure is back and forth carried out.Room in the middle of switch turn-knob (8) is placed, indicator light (13) and electrical appliance all must not be electric, and promptly whole circuit is closed.
